The History Of Bitumen Engineering Essay
The History Of Bitumen Engineering EssayBitumen is described as man softs oldest engineering science material. This fact is support by almost evidence. Back at the m, nearly 3000 years BC, the Sumerians in Mesopotamia utilise bitumen to fasten ivory or pearl into the eye sockets of their statues. They likewise sculptured votive offerings which the mixture of their sculpture is originally from bitumen and clay.From the finding, it is prove that some thousand years later, bitumen was macrocosm use by the early Babylonians as a building material because of its properties as a cement and water proofing agent. Later, bitumen became the standard material and being used in civil engineering and architectural projects to hold bricks and stones together which used to line drains, watercourses and element storage. It was also being used to create damp courses and seal the flat roofs of the houses in the same way as it is used today. It is also authorized in paving (Ask.com, 21 Dec 2 010).Other Evidence found that, rough 600 BC King Nebuchadnezzar of Babylon rebuilt the city wall, which he intends to restrain the water of the Euphrates with incineratet bricks and bitumen because the old wall which is make of dried clay bricks had failed to keep the waters at the bay. The Babylonians had developed a technique using tier of bricks, bitumen and clay which they reinforced with reed for construction purposes. The musical arrangement was so successful whereas they were subject to build towers up to twelve storeys mettlesome. The evidence is proven when archeologists excavating the site of the ancient city and they found traces that bitumen had been used for the construction of the building. rather of using bitumen for construction, the reason why bitumen was widely used in this argona was its avail top executive in discordant somas. It faecal matter be found in certain places where we bear find it easily. It was also available as a solid material in the for m of bituminous limestone, which was used as the basis for shrimpy carvings. Because of its availability, bitumen has taken parts in many great legends of Biblical and pre-Biblical times. It is said that, bitumen has being used in the building of the Tower of Babel and for the waterproofing of Noahs Ark and Moses wicker basket (Zayn Bilkadi, Dec 1984).The Romans used bitumen for medicinal purposes whereas they use bitumen for preventing and band a number of ailments including b contestation oils, to a faultthache and ringworm. Meanwhile, Roman ladies used bitumen for cosmetic purposes whereas they used bitumen as a direction of beautifying their eyebrows. Bitumen also was being used for maritime usage whereas Christopher Columbus and Sir Walter Raleigh found that the lakes of pave in Trinidad be useful for re-caulking their ships for the return voyage. Apart from maritime usage, bitumen was used mainly for medicinal, cosmetic and crop certificate purposes.On the another(pren ominal) pass away, the German metallurgist Georg Agricola was writing in the early part of the sixteenth atomic number 6 that Bitumen is dod from mineral waters containing oil, also from liquid bitumen and from rocks containing bitumen. Liquid bitumen sometimes floats in full-grown quantities on the get hold of wells, brooks and rivers and is collected with buckets or other pots. Small quantities are collected by means of feathers, linen towels and the bid. The bitumen easily adheres to these objects and is collected in big copper or iron vessels and the fall downer fractions evaporated by modify. The proportion oil is used for opposite purposes and some people mix it with pitch, others with used axle oil to make it thicker.On the other hand, the entry for bitumen in Blounts G issueary published in 1656 defined it as a kind of clay or slime indwellingly clammy, like pitch, growing in some countries of Asia. By the put of the nineteenth century, the usage of bitumen for the road construction is to solve the problem of the dust raised by the horse-drawn traffic in towns. The availability of supply of maw from local sear-gas works led to the use of tar for treating streets and sidewalks. They started to realize the measurable of streets and road which would lead to the unimagined standard of smoothness and enduringness for the elements needed for their knowledgeability in the future. Rock mineral pitch and the Trinidad Lake were the sources of bitumen first used to bind mixtures of aggregates in road building in the modern style. (Asphalt Origin,)Nowadays, a half-sizing scale of high quality bitumen suffer be exploited from rock oil which is a readily available source of low cost. The returnion of bitumen grew with the rise of the motorcar and the universal supplicate for paved highways. The proportion of bitumen which is resulted from oil discolor refining whereas lead that today most bitumen sources is from the distillation of boister ous petroleum oil. (BP , 2010).2.2 BitumenBitumen is a versatile material that is widely used in civil engineering. Bitumen is a mixture of extreme liquid that are black, oily, highly viscous that is a naturally occurring organic product by product of decomposed organic materials. This basically consists of hydrocarbons ,carbon hydrogen the rest becomes oxygen, sulfur, nitrogen and trace the various metals such as nickel, vanadium, lead, chromium, quicksilver and also arsenic, selenium and other toxic elements. Bitumen deal provide good preservation of plants and animal fossils.Bitumen and asphalt is cardinal different things. In American asphalt used to mean bitumen but outside American asphalt refers to the mixture of bitumen and aggregate laid as a road issue.HTOPEKBitumen Definition_filesBitumenInBeaker2.gifFigure 2.1 Bitumen2.3 Sources of bitumenBitumen can be derived from different display movement of sources. It occurs naturally, but for most occasions, the world relie s on petroleum for the supplies of bitumen. The bitumen consists of crude petroleum oil that normally varies between 25% and 40%, but subject of crude oil can vary between 15% and 80% (BP 2010). There are three categorization for crude oil bitumen that is bitumen establishd, paraffin based or bitumen and paraffin based.Bitumen present in the form of colloidal dispersion or in a true solution based on the type of crude petroleum oil. In the refining care for, the proportion of oil to bitumen members changes because of petroleum oil is taken away by distillation. Relatively in few numbers, this particle become closer to one a nonher and their size increase when it is dispersed.At the time the distillation demonstrate stopped, the petroleum becomes a colloidal dispersion of black solid known as asphaltenes. This asphaltenes are dispersed in an oily brown yellow liquid, known as the maltenes fraction. It also answer as a stabilizing agent to keep the asphaltenes in suspension are another classify of hydrocarbon known as resins.Normally bitumen is found in a few forms, from the hard, easily crumbled bitumen in rock asphalt to the softer, more viscous material found in tar sands and so-called asphalt lakes. It is normally consist of varying proportions of mineral and vegetable impurities that need to be extracted before in can be used as engineering material. Bitumen also can be found as asphaltite. It is natural bitumen without an impurity that varies in the standard the asphaltite can be dissolve in carbon disulphide. Natural petroleum like bitumen naturally occurs as the result from the redundant de report cards of marine debris.After thousands of years it has been move done porous rock such as limestone and sandstone often by volcanic action. In certain areas renowned for their petroleum resources, like in the Middle East, semi fluid bitumen can be found sludge out of fissures near alive(p) spring or seeping out of the ground. Rock asphalt, it is mo re expensive to move around and to process. This is because its variable and relative low circumscribe of bitumen and tends to be found away from the places where bitumen needed.It is important to distinguish between bitumen and coal tar. Even though coal tar is black and viscous like bitumen, it is obtained from the carbonization of coal that why it is very different chemical properties. Many part of the world in engineering project, from the construction of transcontinental highways to the waterproofing of flat roof turn ups, depending on the specific spirit of asphalt. oil crude oil processed by the industry to provide all but a small part of this material is important.(BP, 2010)2.4 Manufacturing processManufacturing of bitumen consist of three processes which is refinery process, storage and dispersal.2.4.1 Refinery processIn oil refinery process, the crude oil is divided into different groups based on their boiling range. The first stage of refinery process is atmospheri c distillation. In this process the crude oil is heated approximately 3000 C to 3500 C and the more volatilisable components in the crude oil such as petrol and kerosene are distilled off. Residue from this process called atmosphere residue, which is need further distilled under vanity. Because of the applied vacuum, the effective distillation point is 5000 C 5600 C. this vacuum distillation process produce more volatile products called as vacuum distillates and leaves vacuum residue which is a non volatile residue of high viscosity.Based on the crude oil origin, the vacuum residue can be used directly as bitumen and for some cases of crude oil it necessarily additional process to meet certain specification such as send blowing of the residue. To ensure consistent product, the air blowing needs careful selection and control of process temperature, air rate and residence time. In other hand bitumen are produced by blending vacuum residue with asphaltenes which is derived from t he production of lubricating oils. The selection of crude is the most important element of bitumen manufacture because it is required expertise and experience to yield a satisfactory product.2.4.2 Storage whacking permanent tank made of mild steel plate use to stored bitumen at refineries with capacities of between speed of light and 10000 tones. To make sure the bitumen remain fluid, steam or hot oil is pumped during thaw oils in the heavily insulated tanks.2.4.3 DistributionTo make sure the bitumen not cool and unworkable the product must(prenominal) be kept between 150C-190C throughout the supply chain.The temperature of bitumen can fall about 7oC to 10oC when it is loaded into a road tanker and it allow for continue to fall further while in transit. Most of the bitumen go out be transferred from the refineries using the road tankers with capacities of 10 to 40 tones. The road tanker is insulated by single-compartment tanks, normally with some kind of heating such as heating tubes. Insulated rail cars are sometimes used to transport bitumen to intermediary depots with reheating facilities.2.5 Properties of BitumenBitumen is a durable and strong adhesive use as a binder in many applications with other material without affecting their properties. Its durability is important to major engineering part such as road and water ways. Bitumen is insoluble in water and can be used as an effective water proofing sealant. Bitumen can be used to line watercourses because it resist and do not react with acid, alkalis, salt and does not contaminate water.Bitumen is soften and thermoplastic resin material. Bitumen becomes liquid when heated and seasons when it cools. Bitumen can used easily in the area where its need to used because it can readily be liquified by one of three methods thats applying heat, dissolving it in petroleum effects or dispersing it in water (emulsification). add up production of bitumen is larger use in road construction. This is because bitu men gives flexibility to the mixed mineral aggregates that been used in road construction. It is available with economic cost all around the world.2.6 Types of BitumenThere are several types of the bitumen infra based on BP bitumen 20102.6.1 Paving grade bitumenThis type of bitumen considered as a parent bitumen of the other form of bitumen produced below. It is refined and blended to fulfill the industrial and road engineering specification that considered different climate condition.2.6.2 Cutback bitumenThis type of bitumen has lower viscosity than other types of bitumen. This bitumen has been diluted in order to make it more flow able and suitable for application. Cutback bitumen mostly is used for cold weather bituminous, road construction and maintenance. In cutback bitumen suitable solvent is used to lower the viscosity of the bitumen. Fluidity of bitumen depends on the proportion of solvent and degree of hardness of the bitumen base. Cutback bitumen categorise based to the time it takes to become solid, as rapid curing (RC), medium curing (MC) or impenetrable curing (SC). RC is recommended for surface dressing and patchwork.MC is recommended for premix with less quantity of fine aggregates. SC is used for premix with appreciable quantity of fine aggregates. The solvent used for preparation of cutback of bitumen are white olfactory sensation commonly used for RC grades, kerosene for MC grades and diesel for SC grades. In view of the environment, health and synthetic rubber cutback bitumen cause a problem because the solvent used evaporates and currently the evaporation is regarded as a potentially undesirable characteristic.2.6.3 Bitumen emulsionsFrequently the bitumen that been applied to mineral aggregates substrates in road construction is in the form called bitumen emulsion. Bitumen emulsions are the dispersion of bitumen in an aqueous continuous condition and been stabilized by the addition of emulsifier. Bitumen emulsions are the lofty binder can be used in hill road construction which the process of heating the bitumen or aggregates are not easy in that area.Rapid setting emulsions usually used for surface dressing work, Medium setting emulsions use for premix jobs and patch repairs work and slow setting emulsions are ideal use during rainy season. Around 60% of bitumen content in the emulsion and the left all over is water (Tom V. Mathew and K V Krishna Rao, 2007). During the road construction, these emulsions depart opens down resulting in released of water and the mix will starts to set. Grade of bitumen affect the time of setting. Bitumen emulsion is ideal for used in road construction because it put on low viscosity and workable in ambient temperatures.But to apply this bitumen in road make process, it requires controlled breaking and setting. Bitumen should not break before it is laid on the surface of road but, once it placed, it should break quickly. This implies that the road can be in service without del ay.2.6.4 Modified bitumenModified bitumen is bitumen treated with modifiers. Certain additives added as bitumen modifiers to mitigate the service performance by changing such properties as their durability and hardness. Natural rubber, polymer and thermoplastic are commonly used to modify bitumen. This is an exciting development of growing importance due to the ability of modem technology to satisfy the demands of the bitumen and international market. Modified bitumen will contribute towards a longer road action and lower cost maintenance.2.6.5 Multi-grade BitumenThis type of bitumen is chemically modified bitumen. It has multi properties that are properties of hard paving bitumen at high service temperature with the properties of soft paving grades bitumen at low temperature. Multi-grade bitumen gives improvement in resistance to deformation2.6.6 industrial bitumenIndustrial bitumen also known as oxidized bitumen. This bitumen is made by blowing air through hot paving grade bitum en called blowing process. The result from blowing process is a product that softens bitumen at higher temperature than provide by paving grade bitumen softens. It also has rubberlike properties and its viscosity is less affected by changes in temperature than is the case with paving grade bitumen.2.7 Requirement of BitumenThe some requirement properties of bitumen depend on the mix type and construction. In general, Bitumen should fulfill the following properties (Prof. Tom V. Mathew, 2009)The bitumen should not be highly temperature susceptible during the hottest weather the mix should not become too soft or unstable, and during cold weather the mix should not become too brittle causing cracks.The viscosity of the bitumen at the time of mixing and compaction should be adequate. This can be achieved by use of cutbacks or emulsions of suitable grades or by heating the bitumen and aggregates prior to mixing.There should be adequate affinity and adhesion between the bitumen and aggreg ates used in the mix.2.8 Modification of bitumenMany studies have been conducted in order to improve the performance of bitumen used in road pavement by modified bitumen with other material. Additional materials such as rubber, polymer and epoxy resin have been used as modifier in bitumen in the previous research. This study stresses on the usage of aerify ball modify as an additive in bitumen.2.9 Coal burning at the stake products rain zap modify is one of the coal combustion residues. Coal combustion residuals are formed during coal-burning processes in business leader plants. Coal combustion product consists of several materials (R.Majko, 1996).2.9.1 Fly modifyFly change is the fines modify of coal ash tree particles from combustion of coal. It is called strike down ash because it is transported from combustion chamber by exhaust gases. Fly ash is a fine powder produce from the mineral contain in coal. It also consists of noncombustible mater in coal and a small amount of carbon thats remains because of incomplete combustion. Fly ash is usually light tan in color. It is commonly consists of silt size and clay sized shiny spheres which is gives fly ash a consistency somewhat like talc powder. The property of the fly ash varies based on coal composition used and plant direct system.http//www.undeerc.org/carrc/Assets/Fly modify1.JPGFigure 2.2 fly ash2.9.2 Bottom ashBottom ash and fly ash is two different materials in physical, mineralogical and chemical. Bottom ash is a coarse, granular, and incombustible material which is collected from the bottom of furnaces of combustion of coal in generation of electricity. Different with fly ash, bottom ash coarser than fly ash with grain sizes spanning from fine sand to fine gravel. The type of the bottom ash depends on type of furnaces used to burn a coal.http//www.undeerc.org/carrc/Assets/BottomAsh1.JPGFigure 2.3 bottom ash2.9.3 BOILER SLAGBoiler slag is normally a black granular material with numerous e ngineering uses. It is formed in cyclone timpanis which form a melt ash thats cooled with water. Boiler slag is coarser than fly ash.http//www.undeerc.org/carrc/Assets/BoilerSlag1.JPGFigure 2.4boiler slag2.9.4 FGD GYPSUMFlue gas desulfurization (FGD) gypsum is also can be defined as scrubber gypsum. FGD gypsum is the product from an air pollution control system which is removes sulfur from the flue gas in atomic number 20 based scrubbing systems. It is composed of calcium sulphate and produced by employing forced oxidation in the scrubber. FGD gypsum is most usually used for agricultural activity and for drywall production.http//www.undeerc.org/carrc/Assets/FGDMaterial1.JPGFigure 2.5 FGD gypsum2.10 Production of fly ashFly ash normally produced from burning of coal for power generation. Normally coal is pulverized and blown with air into the combustion chamber. In this part the coal will be ignites, generating heat and producing a molten residue. Then the boiler tubes will extr act heat from the boiler and then cool the gas in the chimney. This make the residue from the combustion of coal harden and produce ash known as coal combustion products. The coarse ash kwon as bottom ash andit will fall at the bottom of coal furnaces. In the other hand, the light ash will the light ash will remain suspended in the flue gas and will be collected by electrostatic precipitators, baghouses, or mechanical collection devices such as cyclones.CDocuments and Settingsto_pekDesktopproduction of fly ash.gifFigure 2.6 production of fly ash (ACAA, 1997)2.11 Utilization and benefit of fly ashFly ash have been used many part of the engineering application around the world. The table below shows the employment of fly ash in the engineering part. (Fly ash facts for highway engineers, 2003).ApplicationBenefitused in Portland cement concrete (PCC)-improved workability-decrease water demand-reduced bleeding-improved durabilityused in stabilized base course-provide a strong and durabl e mixture-lower cost-suitable for using recycled base material-increased goose egg efficiencyused in flowable fill-allows placement under freezing conditions-reach 100% density with no compactive effort-increase scandal bearing capacity-increase the speed and ease of backfilling operationsUsed in soil improvement-eliminates need for expensive materials-expedites construction works by improving unstable subgrade By improve subgrade conditions, cost saving through reduction in required pavement thickness.Used in asphalt pavement-reduce potential of asphalt stripping due to hydrophobic properties of fly ash-reduce stripping because fly ash consist of lime-a lower cost than other fillerUsed in grouts for pavement subsealing-develop high ultimate strength-accomplished quickly with minimum effect to the traffic flow.-used to correct undermining without2.12 Type of fly ashFly ash is collected use electrostatic precipitators or bag houses and then transferred to large silos for shipment. Fly ash divided base on precise particle size requirement, thus secure a uniform and quality of product. There are 2 different type of fly ash from combustion of coal in large power plant which is class C and class F.2.12.1 score C screen out C fly ash is produced usually from lignite and sub-bituminous coals and normally contains significant amount of Calcium Hydroxide (CaO) or lime (Cockrell et. al., 1970). Fly ash class C will harden when exposure to the water. Class C normally contains more than 15% of lime and can reach until 30% of the composition (Dr. Kamar Shah Ariffin, 2007). Higher of CaO in class C fly ash make it more special with self hardening characteristic. This is because calcium is a good adhesive agent. The existence of pozzolan properties in the fly ash class c make it different from fly ash class F.2.12.2 Class FClass F fly ash is produced from bituminous coals and burning anthracite .Class F is normally contains greater gang of silica, alumina and iron about 70% of the composition but low in lime content usually under about 15% of the composition (Dr. Kamar Shah Ariffin, 2007). This fly ash has Siliceous and aluminous material, which itself possesses trivial or no cementitious value but in finely divided form and in the presence of moisture, chemically react withCalcium hydroxide at ordinary temperature to form cementitious compounds (Chu et. al.,1993).2.13 character of fly ash2.13.1 Size and shapeFly ash consist of powdery and fine particle that are in spherical shape, either in solid or hollow and mostly vitrified in nature. The carbonaceous in fly ash consist of angular particles. The particle size distribution of bituminous coal fly ashes is usually similar to the silt which is less than a 0.075 mm or No. 200 sieve.Sub bituminous coal fly ashes are similar to the silt size and it is slightly coarser than bituminous coal fly ashes. A coarser particle can result in a less reactive ash and could contain higher carbon contents.Figure 2.7 Fly ash particles at 2,000x magnification2.13.2 ColorBy depending on the amount of unburned carbon in the ash, the color of fly ash can be found and vary from tan to gray to black. If the fly ash contains low carbon, the color will be lighter. Lignite or sub bituminous fly ashes are typically light tan to buff in color, representing relatively low quantities of carbon in addition to the presence of some lime or calcium. However, bituminous fly ashes are usually some shade of gray, with the lighter sunglasses of gray generally indicating a higher quality of ash. Figure 2.8 typical fly ash colorize2.13.3 Specific gravityThe specific gravity of fly ash is generally varies between 2.1to 3.0 whereas the specific surface area are varies in range from 170 to 1000 m2/kg that been measured by the Blaine air permeability method.2.13.4 Loss of ignitionLoss of ignition is a measured of remaining unburned carbon in a coal. It is a critical property of fly ash need to be measured, especial ly for concrete applications. High carbon levels, the type of carbon, the interaction of soluble ions in fly ash, and the variability of carbon content can cause air entrainment problem in fresh concrete and can affect the durability of the concrete. In some application of fly ash are not affected by the loss of ignition such as filler in asphalt and flowable fill can accept fly ash with high content of carbon.2.13.4 ChemistryChemical compositions of the coal mainly affect the chemical constituents of fly ash. Depending on the coal combustion technology used, the fly ash can be significantly different even though they are produced from the same source and similar chemical composition. Therefore the ash hydration properties with the leach characteristic can vary a lot between generating facilities.The combustion and glassification process used at certain power plant will affect the quantity of crystalline material versus glassy degree material because these two substances were depen ds on these two process. When the maximum temperature of the combustion process is above approximately 12000 C and the cooling time is short, the ash produced is mostly glassy phase material (McCarthy et. al., 1987). Crystalline phase calcium compounds are formed where boiler design or operation allows an extra gradual cooling of the ash particles.The factors that affect the hydration and leaching properties of fly ash such as the relative proportion of the spherical glassy phase and crystalline materials, the size distribution of the ash, the chemical nature of glass phase, the type of crystalline material, the nature and the percentage of unburned carbon (Roy et.al, 1985).Generally, the most important factors that influenced the mineralogy of coal fly ash are (Baker, 1987)Chemical composition of the coalCoal combustion process including coal pulverization, combustion, flue gas clean up, and fly ash collection operationsAdditives used, including oil additives for flame stabilizatio n and corrosion control additives.The minerals present in the coal dictates the elemental composition of the fly ash. The boiler design and operation dictated the mineralogy of the ash.2.13.5 Chemical Requirements for Fly Ash Classification(Dr. Kamar Shah Ariffin, 2007)PropertiesFly Ash ClassClass FClass CSilicon dioxide (SiO2) sum total aluminum oxide (Al2O3) plus iron oxide (Fe2O3), min, %70.050.0Sulfur trioxide (SO3), max, %5.05.0Moisture Content, max, %3.03.0Loss on ignition, max, %6.06.0

The 4 Gospels and their Themes
The 4 Gospels and their ThemesThe authors of the four church doctrines in the book of rate had a specific group of people they wrote to and in this assignment I am going to smack at those specific people and what the authors give tongue to almost the life and work of delivery boy. I am going to in analogous manner going to look at the main themes of these four gospel singings, beginning from Matthew to magic.The author of the book of Matthew is the Apostle Matthew who was ane of Jesus disciples. The gospel of Matthew was written in Greek. The author wrote to a particular group of people gener whollyy Greek speaking Jews, even though the author wrote to sealed group of people the writing does endure a worldwide outlook. Matthew concentrated more on the fulfilment of the Old Testament than the writers of the other gospels. In Matthew Jesus teaching pointed to the blessings of the kingdom being extended to gentiles.MATTHEWS MAIN THEMESThe main direct of Matthew is to prove that Jesus Christ is the Messiah which means the anointed one. Jesus can also be interpreted as Joshua in Greek which means the Lord saves. Matthewss goal was to convince his readers that the King of kings has come, with this in mind he uses speech and names that the Jews atomic number 18 familiar with. Also unique to Matthew is the expression, that it might be fulfilled which is spoken by various prophets.1THE MAIN PURPOSE AND focusing OF MARKThe gospel of Mark was written by toilette Mark. Mark was a close associate of peter, it was from Peter that he received the tradition of things done and said by the Lord Jesus Christ. Mark has more of the preaching of Peter, put together by John Mark. According to early church tradition Mark was written in the region of Italy more specific anyy in Rome. In book of Mark John Mark explains Jewish customs and interprets Aramaic speech John Mark beted to wealthy person an interest in persecution and martyrdom. John Mark wrote that th e suffering Jesus was also the Son of matinee idol, the Son of Man, the Christ and the Lord.MARKMAIN THEMESMarks gospel is simple and holds an important account of the ministry of Jesus Christ, with an emphasis on more of what Jesus did than what he said. Mark moves quickly from one fit in Jesus ministry to a nonher. Even though Mark bases his emphasis on the good-will he does not neglect the deity of Christ. Mark wrote to strengthen and guide the Roman considerrs who were being persecuted by Nero. After the remainder of Peter and eyewitnesses to Jesus life, this gospel message needed to be written down.2THE MAIN PURPOSE AND FOCUS IN LUKEThe writers name is not mentioned but evidence points to Luke. The gospel of Luke was written to Theophilus and the message in this gospel was meant for his own instruction and also for those among whom the book would be distributed. Luke was probably written around A.D. 59-63. The book of Luke would devote likely been written in Rome. Luke had an outstanding command of the Greek language. Lukes words in general seem to herald geographical and cultural sensitivity. Lukes gospel centers on Gods plan to provide salvation to the world.LUKEMAIN THEMESLuke was written to strengthen the faith of all believers and to give an answer to the unbelievers. It was written to displace and unveil the false reports approximately Jesus. This third gospel bring ins the works and teachings of Jesus that are especially vital for understanding the way of salvation. The primary two chapters of Luke emphasize the Old Testament and its promises of a Messiah while the third and part of the fourth chapters show clearly that Jesus is the Messiah, who can fight against the evil one, Luke continues in the rest of the chapters to write about the life and works of Jesus and everything that had been revealed by the law, the prophets and the Psalms about Jesus had been fulfilled.3Luke often stressed the gentlemans gentleman and compassion of Jesus. Lukes favourite expression is the Son of Man. The disciples were witnesses of to this fact and their mission was to share this Good News with all nations.THE MAIN PURPOSE AND FOCUS IN JOHNSome translators have felt that Johns aim was to present a forth from a different view point the Christian message that would appeal to Greek thinkers. John would have been thinking of the Greek readers some of whom were being influenced by heresy. John main purpose was evangelistic, to build up believers as well as to win new converts. John also focuses on Jesus claim that He was God by including Christs seven I am statements. John records certain occasions when Jesus equals Himself with the Old Testament I AM. John 858 Most assuredly, I say to you, before Abraham was, I AM.JOHN MAIN THEMESThe writer of John also said that These are written that you may believe that Jesus Christ the Son of God and that believing you may have life in His name John 2031. John also speaks of Jesus as the anteceden t divine Word who became a human being so as to speak the words of God, reveal the glory of Gods grace and truth, to put a bridge between the children of light and the children of darkness, to bring judgment on the unbelieving world and to give eternal life through the gift of the Holy Spirit to all believe and abide in Jesus. John wrote that Jesus was and is the the Nazarene of the world.4John reveals the Bibles most important message, believe and follow Jesus, because He is the way to eternal life. John speaks of Jesus as the light of the world and the lucre of life, the way, the life and the good shepherd.CONCLUSIONThe four canonical gospels are very detailed and actual about the life and work of Christ. Matthew writing to prove to the Jews that Jesus is their Messiah, while Mark stressed the humanity of Jesus but he does not neglect His deity. Luke wanted to show that the place of the gentile Christian in Gods kingdom is based on the teachings of Jesus. Luke main theme is the nature of Jesus Christ the Nazarene ship and mission. The gospel of Luke presents Jesus in ways that would appeal to an audience of high minded gentiles. The gospel of John is presented firstly with a prologue or introduction. John speaks of Jesus as one sent from God to reveal His love and grace to man. All the four gospels have unique story on the life and ministry of Jesus Christ and they all speak of one person only Jesus who is the saviour of the Jews and the saviour of the world. All the resources I used are very helpful for doing a research like this one and I would recommend any theological student to use these books when doing their essays or research work.5
Psychology Concerns
Psychology ConcernsPsychology concerns itself with the understanding of human bearing. In order to do this effectively, psychologists example a diverse range of purviews, even when researching a single theme. This assignment intends to discuss the claim that at that place is a lot to be gained by thinking a outlet in psychology from much(prenominal) than one perspective. In order to discuss this claim, it will be necessary to provide definition of the basis conflict, coexist and complement. These terms will then be applied to the themes of actors line and meaning and sex and gender in order to provide discussion of the claim made. It will become appargonnt that due to the complexness and multidimensional nature of these perspectives, the claim is truthful.Different psychologists ease up taken different perspectives on single psychological issues, they have introduced differing theories and carried out research from their chosen perspective in order to achieve the evidenc e undeniable to support these claims. These differing perspectives may conflict, (where the contrasting claims of different perspectives be mutu all toldy exclusive and potfulnot be resolved). They may be complimentary (where contrasting claims atomic number 18 mutually compatible and basin be accommodated inside a joint explanatory framework) or they may coexist (when particular perspectives, even in the same topic area, have no real point of contact they neither conflict nor complement one an opposite)(Cooper Roth 2007.)There are three perspectives involved in the research into language and meaning. These are evolutionary, mixer constructionist and cognitive. Evolutionary perspective investigates the invite of evolution on behavior it looks at language as a characteristic that is obtained at species take aim and that evolution creates the meaningThe evolutionary perspective concerns itself with the influence that evolution is believed to have had upon behavior. This pers pective looks at language as a characteristic gained at species level, proposing that the meaning of language was created via evolution. The process of evolution has created linguistic ability and in that locationfore the capacity for meaning to be applied to language. Scientific investigations into the study of animals have highlighted that language in humans are different in comparison to that of non-humans. Pinker and Bloom (1990) suggest that language has numerous productive advantages it was also proposed that the well-disposed significance of language has had great impact on human evolution. Evolutionary psychologists neck language as being uniquely human and dependent upon subtle and meaningful interactions with opposites, this exemplifies the evolutionary perspectives coexistence with the mixer constructionist perspective.Leading on, the fond constructionist perspective looks at language as the way in which people, by means of social interactions with others, const ruct their world. This perspective has been evidenced via hermeneutic studies. It is also proposed that language and meaning plays as role in the pursuit of goals and purposes of everyday life (Cooper and Kaye 2007). This concept regarding the pursuit of goals is not unlike the idea proposed in evolutionary psychology that there are evolutionary factors at play when advantageous adaptive characteristics are passed through generations. These perspectives together, demonstrate that in unveiling of meaning for individuals external factors are influential, thus demonstrating coexistence.Cognitive psychologists take a contrasting approach to language their perspective is that of a information processing system within the person. A computational model is used to hypothesise the contribution of both bottom-up and top-down processing of information, which underlies the creation of meaning. Evidence in support of this is obtained though scientific experiments. The cognitive approach purport s that meaning precedes language. Therefore confabulation is considered to be the transmission of meanings between individual speakers, in contrast the perspective adopted by social constructionists claim that meaning is created between people within the goals and purpose of the conversation, this is often disputed by the persons implicated (Cooper Kaye 2007). This demonstrates conflict within the cognitive and social constructionist perspectives.Conflicts can arise within a single perspective as illustrated by Pinker (2000) and Sperber (2000) (both cited by Cooper Kaye 2007), they offered differing explanations regarding views on language within the evolutionary perspective.Pinker proposed that cognitive abilities are built upon the foundation provided by language, nevertheless Sperber proposed that language was a by-product of information processing and these cognitive abilities came first (Cooper Kaye 2007). It is these very conflicts that invite debates within psychology a nd provide the justification for additional research.Moving on the writer will now evaluate coexistence or conflict between the miscellaneous studies conducted with regards to sex and gender. The perspectives used, to search sex and gender, are psychoanalytic, social constructionist, biological and evolutionary perspectives. Again, these perspectives use different research methods and therefore produce differing theories, providing diverse accounts of sex and gender which enhances the complexity of evaluating whether they are complementary, in coexistence or conflict with each other (Hollway et al 2007).The introduction highlighted that perspectives are multidimensional the dimensions of these perspectives that interrelate and are available for comparison are in no way limited to the theories created by each one. Focus is now placed upon the methodologies within the quaternity perspectives mentioned and the corresponding nature vs. nurture debate to evaluate these perspectives r elationships with each other.The perspective that explores the role nature plays in human experience and behavior is the biological and evolutionary. Scientific approaches examining genes and biological structures provide the evidence within this perspective. The biologic perspective proposes that there is an association with genetic and physiological aspects of sex with self-evident implications for gender. PET scanning techniques and the study of material data produced from this provides strength to the claims (Swaab Fliers (1985), Allen Gorski (1990), LeVay (1991), Cooke et al (1998), all cited by Hollway et al (2007), up to now when used in connection with behavioural and cognitive studies they may only be understood within the light of mount and environmental influences (Cooper Roth 2007).Evolutionary psychologists take the view that reproductive stratagies have evolved differently between men and women, this can account for the difference in behavior and sexual attitude . Through experiments (Clark Hatfield (1989) and studies using questionnaires (Buss et al (1992), these claims have been evidenced, however the evidence does not discount other explanations for these behaviors (cited by Hollway et al 2007). The study carried out by Clark Hatfields is self-consistent with the evolutionary perspective, suggesting that behavior is passed through generations as genetically programmed, however the findings also support sexual behavior being influenced by ethnic patterns and social pressure, therefore consistent with the social constructionist perspective (Hollway et al 2007). two perspectives emphasise the influence of nature in human behavior demonstrating they are complimentary to one another, however they can also be considered to coexist as they both use a scientific method using systematic observation of phenomena under experimentation.The hermeneutic method is adopted by both the social constructionist and psychoanalytical approach directed by subjective data collection and analysis and the focus is on interpretation which is provided by a persons beliefs and experiences. The Psychoanalytic perspective recognizes the significance of biological dissimilarity along with the cultural and social meanings of these dissimilarities, and the social constuctionist perspectives explores the significance of culture and context in the construction of ideas about gender (Hollway et al 2007).The argument raised by the social constructionist is that gender is a product of culture rather than something which can be explained through biological sex status, thus conflicting with the general hypothesis raised by biological and evolutionary methodology and in contrast exhibits the effect of nature on gender development. historic and social context provide the framework for experience, behavior and knowledge regarding sex and gender in the social constructionist perspective, additionally discourse analysis has afforded support for gender-appr opriate behaviours between girls and boys, in relation to school activities and subjects and toys (Haywood Mac an Ghaill (1996), cited by Hollway et al 2007).The psychodynamic perspective attempts to comprehend how girls and boys obtain a sexed and gendered sense of self, as they grow up, within the family context. This perspective acknowledges the significance of biological and societal accounts an exemplar is exploring how a baby, sexed by its biology and gendered by society, buzz offs psychological gender that becomes fundamental to its later development as a person (Hollway et al 2007). parallel with the social constructionist perspective, social discourses are assessed, accordingly the two perspectives are complementary as they both acquire understanding of experiences being gendered through the hermeneutic approach.It is however emphasized by Cooper Roth (2007) that psychoanalysis, unlike most(prenominal) other perspectives, is unable to validate its claims. Psychoanalysi s is unique in recognizing the role of biological and social factors, hence that nature and nurture are both equally significant within sex and gender, this could therefore draw out to a complementary relationship or even so far as coexisting with all three other perspectives.Together these four perspectives, to differing extents, place significance upon biological and social factors which signifies them complementing one another. callable to the distinctiveness of the claims within each perspective however, an argument could be raised that the perspectives coexist as the differences are significant. In seeking an understanding of a topic such as those outlined in this assignment, various perspectives can be complementary as they all endeavor to elucidate phenomena.In conclusion there is a lot to be gained by studying a topic in psychology from more than one perspective as the propositions considered within psychology are multidimensional for example the theory the methods and da ta used the levels of analysis, and themes such as nature or nurture. Understanding topics such as language and meaning, or sex and gender, is enhanced by the wealth of information that the variety of perspectives offer. By studying a topic in psychology from more than one perspective and evaluating whether perspectives coexist, conflict or complement each other reinforces the dynamism and vibrancy of psychology.

Changes During the Ageing Process
Changes During the agedness ProcessPhysiological and sociological decrepitness is an unpreventable functioning to which, each individual goes through. Although each age touch on varies greatly from each individual to another it tends to speed up as we age. Ageing mountain be defined as increasing the egress and proportion of remote in society (Calasanti Kathleen, 2006)We age from the moment we argon born, how constantly the varietys that occurs during aging proves from losses that is gradual overtime. It is said that loses rout out much start from young braggyhood (mid 20s-30s) because our bodies being able to decline and brinytain health in most individuals, it is said the loss in not sh receive until later on in vivification-time. We lose 1% of pipe organ functionality per year from the age of 30 years old (Martin GM, 2007) the majority of these changes ar not seen until later age 70 (Critchley, 1931, 1934) The considerable difference in the rate of ageing and organ efficiency lies within the presence of affection and/or the ability of the body to adapt to external stress. The three main fashion models of changes that we need to focus on during our ageing offset are physical, mental and social. At any given time, wiz gouge be established or all of them together which can impact on a soulfulnesss case of life. As were all erratic in our own right, each somebodys ageing process can be different ageing hertz.The aider population is anticipate to rise despite the increase in the womens state pension age to 65 between 2010 and 2020 and the increase for both men and women from 65 to 68 between 2024 and 2046. (Parliament, 2010)According to the NHS, individuals are living longer than ever ahead and our society is expanding. With the NHS explaining that with the fastest rise in the oldest old, path that the overall number of masses in our society withhealth or apportion needs has risen. In turn, this has altered the very nature of our health and make out services, with older people straight track the biggest usersAs we get older, it is leafy vegetable for whatsoever reminiscence loss much(prenominal)(prenominal) as forgetting names or appointments, this is expression due to memory being affected by age, stress, tiredness, or certain(p) illnesses and medications (NHS, 2014)Typically common illnesses and affections occurs (however not exclusive to time-worn individuals) is aberration, Cancer and as substantially Arthritis.Dementia is a progressive disease. Affecting all parts of the instinct such as the frontal lobe, occipital lobes, temporal lobe, and parietal lobe. Dementia is a syndrome (a group of related symptoms) associated with an on discharge decline of the brain and its abilities. This acknowledges problems with memory loss, thinking speed, mental agility, language, savvy, judgement (NHS, 2014)According to the Alzheimers Society on that point are around 800,000 people in the UK with dementia. Current statistics show that one in three people over 65 will become dementia, and two thirds of people with dementia are women. Research undertaken by Alzheimers Society has shown that young people also develop dementia and it is not exclusive to elderly people.According to Cancer Research, 2013 Cancer is a disease caused by normal cells changing so that they grow in an anarchical way. The uncontrolled growth causes a lump called a tumour to fix. Age Concern UK, conducted a study in the years between 2009-2011 and effect that the most top 5 cancer diagnosed for men aged 75 and over is prostate, lung, bowel, bladder and stomach cancer. Their research also ground that the top 5 commonly cancer being diagnosed for women over 75 and over breast, bowel, lung, pancreas and Non-Hodgkin Lymphoma cancer. Also shown during this research was that 36% of all cancers are diagnosed in the elderly (UK, 2009-2011)Arthritis is not exclusive to elderly people and it is a invention to say that only elderly people pack arthritis it also affects young individuals also. Arthritis is a common condition that causes pain and inflammation within a joint. In the UK, around 10 million people have arthritis. dickens of the most commonare osteoarthritisand rheumatoid arthritis. (NHS, 2012) According to Arthritis Research UK, 2013 Osteoarthritis is a common form of arthritis statistic shows that 8.5 million people are affected by Osteoarthritis.In people affected by osteoarthritis, the cartilage (connective tissue) between their bones stepwise wastes away, leading to painful rubbing of bone on bone in the joints. The most frequently affected joints are in the hands, spine, knees and hips. Osteoarthritis ofttimes develops in people who are over 50 years of age. However, it can develop at any age as a result of an injury or another joint-related condition (NHS, 2012)The psychological aspect of ageing is a phase of personalised faithfulness with despair (Erik Erikson, 19 50) during the final stages of the cycle of life the individual is lots seeking a palpate of integrity and trying to avoid a sense of despair. Elder age often becomes a time of reflecting behind on their life which al upsets a call back of events during their own personal lifetime. To the extent we have succeeded in effectively solution the problems that had arisen at every stage of life, we have developed a sense of completion and fullness that is to say, the aspect of full life (Gullette, 2004).Societies views on ageing has been deemed as somewhat disconfirming, it has been argued that the older population can be incorrectly so, be a drain on society. Due to advantages in forward-looking medicine and technology it has been clearly proven that there is a wear out lumber of life for older people.The government has also contributed in befriending repair quality of life to over 65s by providing state pension, free TV licence, free bus pass, winter give the axe allowance, help with solicitude nursing fees* (if individual doesnt have any form of assets such as property*) and legislations in place for best interests of individuals and pushing them to remain independent where possible by staying in their own home kind of than carting off elderly people into nursing homes or care homes once they reach h reportway age. Elderly individuals do also contribute back to society such as volunteering, childcare for grandchildren and also, most continue to piss and pay their taxes after the state pension age of 61 and 68 years old.Ageing is different from one individual to another because all human beings are unique in their own right, its hard to pinpoint how the ageing process affects each individual physical, intellectual abilities and psychological quality of life however, individuals needs change as they age and in order to bump into a standard of quality of life their needs should be simultaneously met where possible.During life, we all often begin t o experiences some types of losses this can include loss of many things such as material things health, jobs, homes. Death of relatives, friends and pets. At times, this can come all at once or set-apart out nevertheless losing an object or an individual close to you can be overwhelming sadness period in anyones life which can result in problems physically and mentally such as depression.Dr Elisabeth Kbler-Rosss pioneering research on grief and grieving has do a significant indent on the bereavement and choke off care of those individuals that are grieving. In fact such an idea or understanding of grief was a rare and novel idea before Dr Elisabeth Kbler-Ross 1969 research which inaugurated her five stages of grief which is detailed as first stage, alarm and denial and sometimes overwhelming, the second stage is anger. Dr Kbler-Ross explains that the realisation of pragmatism emerges after the initial shock. The feelings of anger may be directed at the loved one whom passed ov er or people around the person who is grieving. Following from that the third stage of grief is said to be bargaining, the person who is grieving can be thinking the classic should of, could of, would of I manage I would have done this, I wish I would have done that. I wish I would have told them this, seen them more before passing etc. forth stage of the process is said to be depression, a mixture feelings of sadness and mourning and the final stage of the process is acceptance this phase is a mixture of accepting what has happened, knowing that you cannot change the past. Allowing themselves to continue living after a loved one has passed without feeling guilty about moving on.Although the five stages of grief model was initially developed to help health care professionals around the conception understand the grief of their patients and their relatives who are on the verge of passing over, it has now been comprehensively adopted by individuals around the world not practiced me dical professions but individuals who are facing to be in a situation of their loved ones passing over.The stages are arguably an experience during which, the miserable process of the experience of grief are somewhat, easier to understand the grieving process. The idea also provided an in-depth understanding of grief and for helping others cope through personal trauma of grief. Going through grief is understandably, one of the hardest things an individual can ever go through, but realising that they dont have to do it all by their selves can help ease the pain from grieving.These old age there is lot of support groups available for people who are grieving. The support groups can benefit others by sharing their loss and pain by openly talking about their circumstances and feelings is an active step for them to work through their pain and come to term with that has happened to them.Another positive is that by sharing the loss and pain with others going through the same thing, at lon g last the individuals find themselves giving compassion and reaching out to help others within the support group with the hope they will survive through the wicked personal trauma of grief.Although many theories has been developed regarding the ageing process, the speculation of disengagement has generated the most interest to this day (Cumming Henry, 1961) according to their possibleness as people age, they tend to withdraw from society, and this can be mutual, with society. Cumming Henry had argued this was a consequence of people learning within their limitations with age and making way for new generations of people the fill their roles. However, it is said that the disengagement speculation is controversial, and many individuals do not agree with it.One negativity of disengagement is the low self-esteem that can occur of disengaging. This could have a knock on effect of simply not engaging with others if they believe they are not worth it. This qualitative change will ac company the quantitative decrement in social interaction taking place between the elderly and society (Masoro, 2006).Within diverse societies, it is argued that the disengagement theory is a negative one. When the disengagement theory was created by Cumming Henry, the tradition within society back then was allowing older people to live at home with their families rather than using any form of nursing and residential care.The bodily process theory was originally developed by Robert J. Havighurst in 1961 originally the activity theory was conceived as a response to then, the recently published disengagement theory of ageing.As mentioned above, the disengagement model suggested that it is natural for elderly to disengage altogether from society when they realise that they are close to their death. According to activity theorists, as people interact with their environment and each other, they achieve a series of outcomes.As individuals engage within activities, it gives them someth ing to focus on and keeps themselves as well as their brains active which can minimise depression and feelings of being unwanted.The activity theory has been to understand the emotional changes within ageing adults. Research has found that elderly individuals that has remained in employment, or being able to peruse hobbies or day centres etc. can actually improve a quality of life as it keeps themselves busy and actively engaging with others can improve their self-esteem dramatically.As were all unique in our own right, its hard to define ageing process for every whizz human being. But on average, whilst most over 60s might still be in employment, having independence and remaining in their own home and others might be unable to mobilize and anomic their independence and residing in a care home. Following from research of this essay, as long as all elder individuals needs and preferences are met, their quality of life is at a high standard and appropriate help and support is availa ble then processing through the later adult ageing process will be significantly easier for the individual going through the ageing process and dealing with complications that can occur such as higher risk of developing illnesses that can occur as we age.

Elements Of Struggle Between Passion And Reason
Elements Of Struggle Between Passion And ReasonIn nineteenth century literature a lot of importance was devoted to passion and emotional appeal in preference to reason and logic. seminal authorship and fiction were usually charged with passion and struck a chord with the readers. For any work of fiction or non-fiction the main fill needs to retain a reasoncap qualified plot, nucleotide, structure and organization for it to be of sustained popularity and wide readership. The books included in this study, Cry, the Beloved Coun bear witness by Alan Paton and Frankenstein by bloody shame Shelley have elements of some(prenominal) passion and reason hitherto though a clash betwixt these two elements is evident in both stories.Cry, the earnest country, for the unborn child that is the inheritor of our fear. Let him non love the earth besides deeply. Let him not laugh in addition gladly when the water runs through his fingers, nor stand too silent when the mise en scene sun mak es red the veld with fire. Let him not be too moved when the birds of his land are singing, nor give too much of his sum total to a mountain or a valley. For fear impart knock off him of all if he gives too much (Paton 101).In the above lines from the trading floor, the writer brings about the struggle amid the ruleings of ownership and belonging of the protagonist, Stephen Kumalo, and the fear of his beloved country falling apart because of racial discrimination and racial hostilities betwixt the whites and the obtuses in confederation Africa. The other theme of clash is between the pathway to progress and development for the blacks in urban centers like Johannesburg at the follow of the breaking up of families and tribes in rural South Africa. The dichotomy is between progress and urbanization on the one hand and preserving traditions and strengthening relationships on the other. The main themes are of the clash between the privileged and the colonized, the haves and th e have-nots.In Frankenstein, Mary Shelley has drawn the readers attention towards the clash between science and the occult. Victor Frankenstein who creates the hulk represents reason and the monster represents passion.Learn from me, if not by my precepts, at to the lowest degree by my example, how dangerous is the acquirement of knowledge and how much happier that man is who believes his aboriginal town to be the world, than he who aspires to become greater than his nature will allow (Shelley 50).In the above lines, the author has tried to elaborate on the pitfalls that the mere quest for knowledge devoid of responsibility and control trick have on mortal lives. So the struggle in this story is between reason in the form of science and scientific origination against the passion of the monster which is a creation of the scientist. Frankenstein is a story of an dictatorial scientist who in the pursuit of knowledge creates a monster that nobody is able to control and the monster continues to perpetrate atrocities and chaos. It is a lesson for the reader to bear in mind that curiosity and the mission to gain knowledge is good pass ond the seeker of knowledge must also be capable of taking responsibility and have courage to bear negative consequences in flake a need arises.There are a couple of everyday themes in both these novels. The colonizing of black people in South Africa and disbanding families and tribes in order to profit from cheap labor created the monster of racial malicious mischief and lawlessness in Johannesburg. The whites created the black labor force but did nought to ensure that they remain happy and rooted. The abject poerty and dire nutrition conditions of the black workers created the rift between the rich mine and factory owners and the displaced black laborers. Similarly in Frankenstein Victor Frankenstein created the monster but did nothing to provide a sense of belonging and ownership which encouraged the monster to feel diso wned and become wild.The themes of colonialism and imperialism are present in both novels. It is the struggle between the white and black, the rich and poor, the rulers and the ruled in Alan Patons story dapple the theme of the creator and the created permeates Mary Shelleys novel. Isolation and the sense of lack of belonging have created both the monster and Absalom. The monster seeks the love and acknowledgment of his creator while Absalom leaves his village, Ndotsheni, to seek knowledge and employment. So both the monster and Absalom feel set-apart from their people and take to ways that harms others more than they can control.Stephen Kumalo is the pastor of a small village in South Africa and lives in his own world, sort of disconnected with the times and happenings in urbanized centers like Johannesburg. When he comes to Johannesburg to dish out rehabilitate his sister, Gertrude, he is brought face to face with the realities of life in South Africa. He realizes that his wor ld was collapsing and that the main tragedy of his people was that things like relationships and innocence were breaking down and no one was doing anything to mend them. He says, It worthy the white man to break the tribe, but it has not suited him to wee-wee something in its place (Paton 46). Stephen Kumalo is a man obsessed with a mirthful quest to seek his son and rebuild the community. Similarly, Victor Frankenstein is obsessed with desire knowledge and acquiring power. He wanted to play God and bear witness his ability to give life to an animal (Shelley 51).The conclusion of both the stories engenders placid and relative hold. In the end Absalom realizes his mistake and is reconciled to his fate and Stephen Kumalo is able to bring his sister and Absaloms pregnant wife back to the village to try and rebuild his tribe with the help of James Jarvis. The monster in Frankenstein grieves over the death of his creator and is reconciled to his self-imposed exile in the uniting Pole and subsequent death. He realizes that his atrocities in order to seek vindicate did not yield the desired results and he continued to be attached and isolated. In both stories, there is a sense of catharsis with Absalom writing home to his parents and the monster grieving over his master. Even though both ends are tragic there is a faint ray of hope in both novels.
Significance of Security Testing
substance of Security interrogatoryPremalatha SampathAbstract parcel surety testifying is an requisite means which helps to assure that the bundle is trustworthy and secure. It is an idea which has been brought from engineering softw argon package to check whether it keeps on working properly under malicious outbreaks. bundle product shelter scrutiny process is lengthy, complex and costly. It is because several instances of bugs atomic number 18 fly in interrogation on a routine basis. The application readiness perform some additional, unspecified task in the process succession effectively behaving as indicated by the aimments. Thus, to build secure softw ar program as well as meet budget and time constraints it is essential to tension test effort in atomic number 18as that have a larger second of protective cover vulnerabilities. in that locationfore, vulnerabilities ar classified and mixed taxonomies have been created by computer auspices questioners. Along with the taxonomies, there are also various orders and techniques which helps to test the commonly appearing test issues in computer software body. These techniques generally include generic tools, fuzzing, checklists of unpredictable depth and quality, vulnerability s nookyners, hacking or hiring hackers etc.This occupy focuses on the introduction, grandness, vulnerabilities, approaches and methods of bail examination. Articles related to these components were chosen. They were then evaluated on the basis of auspices interrogatory approaches.Further more, the study explores the flaws and vulnerabilities of hostage examen and figures out the importance of shelter examen. Moreover, the research also highlights various methods and techniques of hostage examen. In the end, compiling all the articles research questions like what is the importance of earnest testing and what are the approaches to security testing are answered.IntroductionSecurity is one of the man y aspects of software quality. software system turns out to be more complicated, with the wide utilization of computer which excessively increase software security problems. Software security is the ability of software to provide required function when it is attacked as defined by the originators (Tian-yang, Yin-sheng You-yuan, 2010). on that point are few common types of security testing such(prenominal) as vulnerability assessments, penetration tests, runtime testing and polity review. New vulnerabilities are beingness dis sink ined with the coming of internet age. They are existing because of many reasons woeful development practices, ignoring security policies during design, incorrect configurations, improper initialization, inadequate testing out-of-pocket to deadlines imposed by financial and marketing needs etc. (Preuveneers, Berbers Bhatti, 2008).The meaning of security in the life cycle from network security, to remains security and application security is curren tly recognized by the companies and organizations asa coordinated lengthwise procedure stated by (Felderer, Bchler, Johns, Brucker, Breu Pretschner, 2016). in that locationfore, in trunks to discover which types of vulnerabilities are dominant, security vulnerabilities are categorized so as to focus the type of testing that would be needed to find them. On the basis of these classifications, various taxonomies are developed by computer security researchers. According to the author (AL-Ghamdi, 2013), at the requirements level security should be explicit and moldiness cover two overt functional security and emergent individualities. One groovy approach to cover that is using abuse cases which portrays the carcasss behaviors under attack.Two strategies that must be incorporated by security testing are testing security functionality using standard functional testing techniques and risk ground security testing establish on attack patterns and threat specimens. There are normal ly two categories of vulnerabilities bugs at the execution level and flaws at the design level (Tondel, Jaatun Meland, 2008).The research done in this article evaluates the security testing approaches and the methods in order to detect the flaws and vulnerabilities of security in the software. any this approaches and methods of security testing will help to make the software more secure, flawless and bug-free. Thus, the goal of this study is to find out the signifi nookiece of security testing in todays fastest growing internet age and to unveil developers with an esteemed importance of systems security.The literature review is divided into 4 sections. The commencement exercise section gives the overview of security testing. The next sections answer the research questions like what is the importance of security testing and what are the various approaches to security testing.Literature criticismImportance of Security TestingIn contrast with simple software testing process, provi ding security to a system is exceptionally unpredictable. This is because simple software testing only shows the presence of errors but fails to show the absence of certain(prenominal) types of errors which is ultimately achieved by security testing. As per the author (Khatri, 2014), there are two essential things which should be checked by the system First, rigorousness of implemented security measures. Second, systems behavior when it is attacked by attackers. The loopholes or vulnerabilities in system may cause failure of security functions of system eventually leash to great losses to organization. So, it is extremely fundamental to incorporate testing approaches for entropy protective covering.Security VulnerabilitiesThere are certain types of errors which are termed as security vulnerabilities, flaws or exploits. The authors (Tian-yang, Yin-sheng You-yuan, 2010) states that there are certain flaws present in system design, implementation, operation, management which are r eferred as vulnerabilities. As per (Trpe, 2008), in order to send testing it is important to understand the roots of vulnerabilities and these vulnerabilities vary from system to system.These exploits are broadly categorized on their similarities by (Preuveneers, Berbers Bhatti, 2008) as followsEnvironment variables training that does not alternate across executions of a program is encapsulated by such variables.Buffer Overflows A memory stack is overflowed which leads the program to execute the info after the last address in the stack, generally an attacker gets the skillful control of the system when an executable program builds a root or reign line shell.Operational Misuse Operating a system in a non-secure mode.Data as Instructions or book of account Injections due to improper input checking, scripting languages include information with executable economy which is then executed by the system.Default Settings If default software settings require user intervention to sec ure them they may encounter a risk. coder Backdoors The developers of the software leave the unauthorized access paths for easy access.Numeric Overflows big a lesser or greater value than estimated.Race Conditions displace a string of data before another is executed.Network Exposures It is sham that when messages are sent to a server adequately, clients will check that. entropy Exposure Sensitive information is exposed to unauthorized users which can be used to compromise data or systems.Possible AttacksAccording to the authors (Preuveneers, Berbers Bhatti, 2008), (Felderer, Bchler, Johns, Brucker, Breu Pretschner, 2016) and (AL-Ghamdi, 2013), secure software should achieve security requirements such as reliability, resiliency, and recoverability. because they describe various possible attacks such asInformation manifestation Attacks To disclose sensitive or utilizable data, applications can often be forced. Attacks in this class include directory indexing attacks, path traver sal attacks and tendency of whether the application resources are allocated from a conventional and accessible location.System dependency Attacks By observing the environment of use of the targeted application, vital system resources can be recognized. Attacks of this type include LDAP injection, OS commanding, SQL injection, SSI injection, format strings, large strings, command injection, escape characters, and special/problematic character sets.Authentication/Authorization Attacks These attacks includes both dictionary attacks and common account/password strings and credentials, exploiting key materials in memory and at component boundaries , insufficient and poorly implemented protection and reco rattling of passwords.Logic/Implementation (business model) Attacks For an attacker, the hardest attacks to apply are often the roughly gainful. These include checking for faulty process validation, broadcast temporary files for sensitive information, attempts to mall-treatment verse d functionality to uncover secrets and cause insecure behavior and testing the applications ability to be remote-controlled.Approaches to Security TestingAccording to the author (Khatri, 2014), approach to security testing involves determining who should do it and what activities they should undertake.Who This is because there are two approaches which security testing implicates 1) Functional security testing and 2) Risk-based security testing. Risk-based security testing gets challenging for traditional staff to perform because it is more for expertise and experience people.How There are several testing methods however the issue with each method is the lack of it because most of organizations devote very little time in understanding the non-functional security risks instead it concentrates on features.The two approaches functional and risk-based are defined by the authors (Tndel, Jaatun Jensen, 2008) as followsFunctional security testing On the basis of requirements, this techniq ue will determine whether security mechanisms, such as cryptography settings and access control are executed and configured or not.Adversarial security testing This technique is based on risk-based security testing and determines whether the software contains vulnerabilities by pretending an attackers approach.Methods and Techniques of Security Testing by (Tian-yang, Yin-sheng You-yuan, 2010), (AL-Ghamdi, 2013) and (Felderer, Bchler, Johns, Brucker, Breu Pretschner, 2016).Formal security testingTo build a mathematical model of the software and to provide software form specification supported by some nut specification language is the basic idea of formal method.Model-based security testingA model by the behavior and social structure of software is constructed by model-based testing and then from this test model, test cases are derived.Fault injection based security testingThis testing emphasizes on the interaction points of application and environment, including user input, file system, network interface, and environment variable. hirsute testingTo discover security vulnerability which gets more and more attention, wooly testing is effective. To test program, it would inject random data and evaluate whether it can run normally under the clutter input.Vulnerability scanning testingTo find software security risks, vulnerability testing is used which includes testing space scanning and known defects scanning.Property based testingBy using program slicing technology, this method will extract the code relative to specific property and find infringement of the code against security property specification.White box-based security testingOne of common white-box based testing method is static analysis which is great at finding security bug, such as buffer overflow. It includes main features like deducing, data flow analysis and constraint analysis.Risk-based security testingTo find risky security vulnerabilities as early as possible, risk-based security testing c ombines the risk analysis, security testing with software development lifecycle.DiscussionThere are some type of security vulnerabilities which are more serious or are more common than others, therefore classification and rankings of vulnerabilities can be utilized to focus testing. Today, attacks such as Cross-Site Scripting and SQL injection are very common and new vulnerabilities are still being discovered. Basically, security testing can be divided into security vulnerability testing and security functional testing. To ensure whether software security functions are implemented decently and consistent with security requirements, security functional testing is used. Whereas to discover security vulnerabilities as an attacker, security vulnerability testing is used. Risk-based security testing is useful when a complex system requires numerous tests for adequate coverage in limited time.RecommendationTo build a secure system, security testing is used however it has been overlooked for a long time. Protection and security have been given prime significance in todays world, therefore in programming applications, it is highly recommended to look forward for information and operations security which demands critical consideration but it is rather ignored. There is still nonentity like 100% security. The old way of doing things and traditional methods must change and new methods should be applied in practice if one wants to transmit secure code with confidence.ConclusionThe literature review was done winning 8 articles addressing the topic Significance of Security Testing. This report analyses the definition, classification, importance and approaches to software security testing. Classification of vulnerabilities and flaws were identified and what could be the reason behind happening of these vulnerabilities were discussed. The study also highlighted the various approaches like the functional and risk-based security testing and various methods in detail to tac kle the flaws and errors detected in the system. These methods and techniques helps the system in various aspects like to advance the capability to produce protect and safe software, more cost-effective management of vulnerabilities and measure progress. Though, these approaches and classification makes software secure to a major extent but still security testing has a long way to go.ReferencesAL-Ghamdi, A. S. A. M. (2013, April).

Far Right Propaganda A Historical Analysis
Far Right Propaganda A Historical analysisThe parallels between recent far right wing propaganda and national socialist propaganda go alonging up to world war cardinal.Propaganda is defined in the oxford dictionary as In coiffeion, curiously of a biased or misleading nature, used to promote a political cause or point of view. Propaganda is biased, persuasive and non object a systema skeletale of media usepd to promote a point of view or political stance. Propaganda has been used throughout history to influence and shape views by selectively presenting education and withholding facts. The language and tomography used in political propaganda is carefully selected to conjure an emotional result from an audience quite a than a more rational response.The word propaganda is a word derived from the reach of a new administrative body of the Catholic Church in 1622 entitled Congregatio de Propaganda Fide which translates as Congregation for the propagating the Faith or informa lly moreover propaganda. There are three different types of propaganda black, white and grey. White propaganda is the nearly conceivable and espouses from a tooth root that is identified correctly, and the information in the cognitive content tends to be accurate (Jowett and ODonnell, 2012, p.17). The source is precise much well respected and the information is truthful, barely, presented in a way which is biased to convince the audience that they deal the best fill outledge of political ideology. The best example of white propaganda is newsprint publishing throughout history as the source is clear however the content can vary depending on the political views of the writer. Grey propaganda is a type of propaganda that falls between black and white propaganda it is often created by a private organisation yet presents itself like a credible source. Grey propaganda can be described best as The source may or may not be correctly identified, and the truth of the information is un reliable (Jowett and ODonnell, 2012 p.20). In recent years the problem of finagle news stories on discover is the most intelligible version of modern grey propaganda. obtuse propaganda is the least credible type of propaganda and often comes from a fake or unidentified source and is used predominantly to spread lies. Black propaganda is often created with the intention of universe portrayed as a credible source. A good example of the use of black propaganda was seen in the run-up to the 2007 federal formal election in Australia. Members of the liberal p artistryy circulated flyers around Sydney under the pretense of being circulated by an organisation called the Islamic Australia Federation. These flyers recognized the Australian Labour party for supporting Islamic fundamentalists and terrorism. The purpose of this was to conjure business organization in the public and alter their political alliances.In Germany in the 1930s, propaganda played a very large part in how th e Nazi Party were perceived. check over what the great unwashed in Germany could see was heavily restricted which meant obvious propaganda was used in all media including literature, art, music, film, newspapers and radio. Dr Joseph Goebbels was put in charge of propaganda with the official title Minister of Propaganda and National Enlightenment. It was his role to ensure nobody in Germany could see or read anything that could be damaging to the reputation of the Nazi party.Graphic design is key in conveying the messages of propaganda. All art is propaganda. It is universally and inescapably propaganda sometimes unconsciously, save often gively, propaganda. This is according to Upton Sinclair, an American author and political commentator, and in the case of Nazi propaganda this was very align and deliberate. Views put across in Nazi propaganda seemed extreme in modern Britain until very recently. The idea that battalion were taken in by this exigent propaganda seems ludicrous, until you start to look at the startling correlation between imagery and views in Nazi propaganda leading up to world war two and propaganda created by far right groups in recent years.Historical mount and Nazi propaganda paragraphBrexit ParagraphLeft A Nazi propaganda film. The images come from a BBC documentary currently on Netflix called Auschwitz Nazis and the final solution.Right Nigel Farage, draw of UKIP during the European referendum, standing in front of a UKIP pro-leave poster. Despite not being part of the official leave campaign during the European Referendum in June 2015, Nigel Farage, Leader of far right political party UKIP made unvaried headlines throughout the campaign. The most controversial piece of propaganda over the last few weeks of campaigning was UKIPs breaking point poster which depicts a long line of refugees trying to reach Europe. The photograph was taken by photographer Jeff Mitchell and shows refugees modification through an old railway line in Sl ovenia after being kettled by police, explaining the traumatised look on their faces. Jeff Mitchell intentionally took the shot to show the mountain of people from an impartial humanitarian point of view as he explains It was a very flat walk, so I scoped out a bridge to shoot from. I knew exactly what lens I was tone ending to use, to compress the group, to show how many people were there. I could admit walked with them the integral length, photographing how people were struggling, but you can sum it all up in one picture.. The photograph is now one of the most memorable images of the right wing pro-leave campaign and far right administration in Britain. The text and design of the poster is besides important. The banner along the bottom is very simple and easy to read and also looks extremely similar to the format of the leave.eu official campaigns posters which could potentially direct been think to blur the line between the two.The Breaking Point poster was intended to ev oke an emotional response from the audience. The image of the hundreds of predominantly male refugees was used so that British people voting in the referendum would feel fear or perhaps a need to protect their country from the unknown. Far right groups use fear and scaremongering in this way to incite hatred of foreigners and different races and religions. In the lead up to World War II, Nazi propaganda films were also used to outpouring this same sense of fear using volume of people. In my graduation gear image you can see a still from a 1941 Nazi newsreel showing the march of Bessarabian Jews in Romania. In this same newsreel, the Jews are also referred to as parasites which links strongly to how refugees are perceived today. The two images have a lot in common in both bearing and political message and both aim to evoke the same response from the audience fear and hatred. Although, different Medias, the photography is similar and has been directly planned in order to show as many people as possible in the image. In the case of the Breaking Point poster, UKIP have appropriated this image for their own political cause, whereas in the Nazi newsreel, it is highly potential this was done intentionally. Another parallel between the two images which explain their form and the faces of those photographed is the events leading up to the images. In the photograph of the Jews travelling through Romania they were agonistic to walk in such a line similarly to the refugees in Slovenia who were kettled by police before being walked in a certain direction.But the most brilliant propagandist technique will sire no success unless one fundamental principle is borne in take heed constantly and with unflagging attention. It must confine itself to a few points and resound them over and over. Here, as so often in this world, persistence is the first and most important requirement for success. Adolf HitlerThe most effective way to eradicate people is to deny and obliterat e their own understanding of their history. George OrwellUS politicsThe American fascists are most easily recognized by their deliberate perversion of truth and fact. Their newspapers and propaganda carefully cultivate both fissure of disunity, every crack in the common front against fascism. Henry A.

And its subtle, but its actually a much stronger propaganda machine than the Nazis had but its funded in a different way.
