Report of cyclone efficiency method

Report of cyclone efficiency method Abstract:   Ã‚  Ã‚  Ã‚  Ã‚  This report is concerned about cyclone efficiency. The method cyclone is used to remove particles from gaseous waste streams in the experiment. Based on the literature search, more knowledge has been known about particle collecting and particle sizing. Qualitative method is used to describe the particle size distribution using the ELPI device. The cyclone efficiency results are analyzed with graphs and discussion. Comments on the most appropriate methods of control of particles of the size are given at last in the section of discussion. Introduction: Background: Air pollution is man-made harmful materials and particulars in the air, which produce disadvantageous effects to peoples health. It is a big problem, however, public was not focused on air pollution until 1969. Before that time, the air pollution increased dramatically. We impossibly solve the air pollution problems by blowing away the poisonous air and the particles in the air. The most important thing is whether we could control them by reducing pollutant emissions. Air pollution problem is not a single problem, but a series of related problems. The overall air problem basically includes the following form, emissions, transport, dilution, and modification in the atmosphere, which effects on people, property, and the environment. We are unlikely to find a good and easy way to solve all these problems. Instead, we will have to make some steps to achieve the goals such as doing some research on particulate removal from gaseous waste streams so that we can improve the air quality. Name of Technology: Cyclones This type of technology is a part of the group of air pollution controls collectively referred to as pre-cleaners, because they are oftentimes used to reduce the inlet loading of particulate matter (PM) to downstream collection devices by removing larger, abrasive particles. Cyclones are also referred to as cyclone collectors, cyclone separators, centrifugal separators, and inertial separators. In applications where many small cyclones are operating in parallel, the entire system is called a multiple tube cyclone, multi-cyclone, or multi-clone. Type of Technology: Removals of PM by centrifugal and inertial forces are induced by forcing particulate-laden gas to change direction. Applicable Pollutants: Cyclones are used to control PM, and primarily PM greater than 10 micrometers (Fm) in aerodynamic diameter. However, there are high efficiency cyclones designed to be effective for PM less than or equal to 10 Fm and less than or equal to 2.5 Fm in aerodynamic diameter (PM10 and PM2.5). Although cyclones may be used to collect particles larger than 200 Fm, gravity settling chambers or simple momentum separators is usually satisfactory and less subject to abrasion. Achievable Emission Limits/Reductions: The collection efficiency of cyclones varies as a function of particle size and cyclone design. Cyclone efficiency generally increases with particle size and/or density, inlet duct velocity, cyclone body length, number of gas revolutions in the cyclone, ratio of cyclone body diameter to gas exit diameter, dust loading, and smoothness of the cyclone inner wall. Cyclone efficiency will decrease with increases in gas viscosity, body diameter, gas exit diameter, gas inlet duct area, and gas density. A common factor contributing to decreased control efficiencies in cyclones is leakage of air into the dust outlet. Control efficiency ranges for single cyclones are often based on three classifications of cyclone, i.e., conventional, high-efficiency, and high-throughput. The control efficiency range for conventional single cyclones is estimated to be 70 to 90 percent for PM, 30 to 90 percent for PM10, and 0 to 40 percent for PM2.5. High efficiency single cyclones are designed to achieve higher control of smaller particles than conventional cyclones. Summary: This experiment is focused on the sizing of airborne dust or sprays and with one specific method of particulate removal from gas streams (a cyclone). Our major aims are to assess possible dust hazards when handling powders, the efficiency of filters and other arresters and assess the properties of aerosol. Literature Search: Control of primary particulates:   Ã‚  Ã‚  Ã‚  Ã‚  Most of the fine particles in the air are secondary particles. Many of the primary particles are more toxic than most secondary particles. Though primary particles are generally larger than secondary particles, many primary particles are small enough to be respirable and are thus of health concern.   Ã‚  Ã‚  Ã‚  Ã‚  The first three kinds of control devices are gravity settlers, cyclone separators, and electrostatic precipitators. All function is driving the particles to a solid wall, where they adhere to each other to form agglomerates that can be removed from the collection device and disposed of. Choosing a Collector: Gravity settling chambers, cyclones, and ESPs work by driving the particles to a solid wall where they form agglomerates that can be collected. These three devices have similar design equations. Filters and scrubbers divide the flow. They have different design equations from wall collection devices and from each other. Both surface and depth filters are used for particle collection. Surface filters are used to collect most of the particles in a heavily laden gas stream. Depth filters are mostly used for the final cleanup of air or gas that must be very clean or for fine liquid drops, which coalesce on them and then drop off. To collect small particles, a scrubber must have a very large relative velocity between the gas being cleaned and the liquid drops. For this reason co-flow scrubbers are most often used. The venture scrubber is the most widely used type of co-flow scrubber. Particle Size Analysis: In many powder and material processing operations, particle size and size distribution play an important role in determining the bulk properties. Describing the size distribution of the particles which make up a powder is therefore central in characterizing the powder. In a number of industrial applications, a single number will be required to characterize the particle size. This can only be done accurately and easily with a mono-sized distribution of spheres or cubes. Real particles with shapes which require more than one dimension to describe and real powders with particles in a range of sizes mean that in practice the identification of single number to describe the size of the particles is far from straightforward. Separation of Particles from a Gas: Gas Cyclones Gas Cyclones Description: Cyclones are extensively used for removing particles from gas stream. The most common type of cyclone is the reverse flow type. Inlet gas is brought tangentially into the cylindrical section and a strong vortex is created inside the cyclone body. Particles in the gas are subjected to centrifugal forces which move them radially outwards, against the inward flow of gas and towards the inside surface of the cyclone on which the solids separate. The direction of flow of the vortex reverses near the bottom of the cylindrical section and the gas leaves the cyclone via the outlet in the top. The solids at the wall of the cyclone are pushed downwards by the outer vortex and out of the solids exit. Gravity has little effect on the operation of the cyclone. Efficiency of Separation:   Ã‚  Ã‚  Ã‚  Ã‚  Consider a cyclone to which the solids mass flow rate is M, the mass flow discharged from the solids exit orifice is Mc (known as the fine product). The total material balance on the solids over this cyclone may be written: Total: M=Mf+Mc and the ‘component material balance for each particle size x (assuming no breakage or growth or particles within the cyclone) is: Component: M (dF/dx) = Mf (dFf/dx) + Mc (dFc/dx) where, dF/dx, dFf /dx and dFc/dx are the differential frequency size distributions by mass (i.e. mass fraction of size x) for the feed, fine product and coarse product respectively. F, Ff and Fc are the cumulative frequency size distributions by mass (mass fraction less than size x) for the feed, fine product and coarse product respectively. Experimental:   Ã‚  Ã‚  Ã‚  Ã‚  Remove and reweigh the filter and the hopper. Calculate the efficiency of cyclone. The instrument EPLI which is widely used for determining near real-time measurements was used to do this experiment. It can measure particles within the size range 30nm up to 10um on the basis of their aerodynamic diameter. In this experiment, two kinds of particles, MgO, and fly ash particles were measured by the demonstrator. And four groups of data were obtained in this experiment, the first two groups are for fly ash particles and the second two groups are for MgO. Results: During operation particles are drawn through a charger where they will receive a charge, before passing into the impactor which contains a number of stages, each one connected to a multi-channel electrometer. Depending on the aerodynamic size of the particles they will be impacted on the different stages. The current values obtained from the different stages are converted to a size distribution, a graph of which is shown in Figure 1. Three kinds of particle have different peak value of number concentration. The peak value of MgO is around 2000 particles/cm3, fly ash particle is about 1500 particles/cm3, and Atmospheric particle is above 2500 particles/cm3. The peak of fly ash particles is lower than MgO particles. Discussion: It can be seen from Figure 1 that there are clearly overlapping size distributions present in the sample of Atmospheric particles, MgO particles and fly ash particles. Real samples always contain particles with more than one source. Atmospheric dust might for example contain pollen as well as pollutants. The size distribution will then have two peak values. In this experiment, fly ash particles can be found a bit larger than MgO particles. And the color of fly ash is darker than MgO, MgO is white. In addition, it can be seen in figure 1 that the start point of MgO particles is much higher than fly ash particles. Because of influence of the distribution and size, the cyclone efficiency of fly ash particles is a little bit higher than MgO particles in average. From Figure 1, it also can be seen that the number concentration of MgO particles firstly reach its peek value, and then the fly ash particles get its peak. Atmospheric particles obtain its peak value at almost the same time as fly ash particles. In the other hand, the distribution of the total number of MgO and fly ash particles is different, it can be seen from Figure 1 that as the diameter of MgO increase, the total number firstly increase, then go down, and then go up again. But the curve of fly ash does not have this phenomenon. Its curve only has one wave crest and compared with MgO, the number concentration of fly ash first get the value 0. In addition, it is worthy to note that the atmospheric particles curve almost has the same shape as fly ashs curve. The only big difference is that the atmospheric particles curve has a much higher peak value of number concentration. In the experiment, the particles escaping from the cyclone in the process might lose, which could influence the cyclone efficiency. Also, from this experiment, it can be found that there are some advantages of using cyclone method to calculate the efficiency. The first one is that temperature and pressure limitations are only dependent on the materials of construction; the second one, dry collection and disposal; and the third one is relatively small space requirements. However, there are some disadvantages of using cyclone. Firstly, it is unable to handle sticky or tacky materials. Secondly, high efficiency units might experience high pressure drops. In the industry, cyclone is normally for relatively big particles, and ESP or fabric filter is for smaller particles. Because in the atmosphere the toxic particles are generally smaller than fine particles, ESP and fabric filter should be used more than other instrument. The electrostatic precipitator (ESP) is like a gravity settler or centrifugal separator, but electrostatic force drives the particles to the wall. It is effective on much smaller particles than the previous two devices.

The Collection of Intelligence Information in the Current World

â€Å"So much information is now available on the Internet (even if some of it is inaccurate) that intelligence collection in the traditional sense is now no longer necessary†. Do you agree? What kinds of information might or might not be available? As a decision-maker would you agree to give up intelligence sources? Introduction Governments â€Å"run â€Å" on information. They need to be constantly aware of what is occurring around them, and how this could affect their interests, in order to take the right decisions at the right time.However not all the information they need is publicly available, which is why intelligence agencies were created with the objective of collecting, analysing and using confidential information, obtained secretly, to advise decision-makers. The collection process takes place after certain tasks have been assigned by the decision-makers, and consists of acquiring the necessary information which will then be treated at a later stage of the intelli gence cycle.Traditionally, the collecting process of such agencies comes from either human intelligence, meaning information directly transmitted from a trustworthy person to an intelligence officer, or technical intelligence, which uses technology and machines to obtain this information. Today, however, the collection process of all information-seeking organizations has been transformed with the Internet. It is the largest, fastest-expanding source of information worldwide, where anybody on any point of the globe can post or have access to information.The impact of the Internet on Intelligence agencies is undoubtable, and it has become a major component of open-source intelligence (OSINT, the process of acquiring information from public sources to be treated and put in use for intelligence purposes). It provides information which is cheaper, more accessible, more timely and easier to disseminate in a shorter time. This has lead some people to believe that: â€Å"So much informatio n is now available on the Internet (even if some of it is inaccurate) that intelligence collection in the traditional sense is now no onger necessary†. Has the Internet revolutionized the information collection process to the point of making the traditional methods obsolete? In this paper, I will defend the view that it has not, thus disagreeing with the statement above[1]. I will discuss that information available on the Internet is no replacement to information collected in the traditional sense, both theoretically (I) and in practice (II), even though it is a useful instrument which can also be used to guide decision-makers (III).I) The theoretical distinction between information available on the Internet and traditional intelligence collection In 2005, General Michael Hayden, from the US Open Source Centre, stated that â€Å"just because information is stolen, it does not make it better†[2]. This is true, however, what if the information was â€Å"stolen† bec ause it was not available anywhere else? One must not confuse the terms information and intelligence. Information is made up of the facts agencies seek; intelligence is the process of acquiring and making use of confidential information which responds to the government's interests.Of course, if this information was available on the Internet, no rational organization would prefer to spend more money, more resources and a greater effort on high-risk operations, which is what information collection implies in the intelligence domain. The problem is that the information intelligence agencies seek is voluntarily hidden by the entity that controls it, which is why it is confidential, and for obvious reasons not posted on the Internet. Moreover, the more people that have a piece of information, the harder it is to have control over it, which incites organizations detaining information to keep it to themselves.By definition, intelligence information is therefore unavailable elsewhere. Conse quently, the information on the Internet has a different content to information coming from intelligence, hence it cannot replace it. Furthermore, the definition of intelligence does not only regard the content of the information, it also concerns how the information is collected. According to David Chuter’s definition, intelligence means that the entity from which information is obtained does not want you to have it, and does not realize you have acquired it.On the contrary, the person posting information on the Internet wants you to have access to it and is aware anybody could acquire it. [3] Therefore, in both aspects of the definition of intelligence, there is a clear distinction between information coming from intelligence and from the Internet, and because of their difference in nature, one cannot replace the other. However, in practice, this theoretical distinction is blurred due to the fact that anybody can post on the Internet, including holders of confidential infor mation.They could, for example, want to harm the person or organization they work for by making such information public through the Internet. II) In practice, the Internet is no replacement to traditional information collection The Commandant of the Marine Corps in 1988, General Alfred Gray Jr. , said that â€Å"most of the intelligence which needs to be known could be obtained via open-source information†[4], which the Internet is a major source of. Undoubtedly, with the huge amount of information available on the Internet, this must be true.There are examples of confidential information been publicly made available through the internet, such as the major Wikileaks information release on confidential subjects- the war in Afghanistan and in Iraq, amongst others. We could then ask ourselves: what if confidential information has been canalized through the Internet and we no longer need intelligence to retrieve it? The information intelligence agencies search for must be importa nt and useful, or it would be irrelevant to the governments that need it. This means it must go through numerous filters and a high discrimination process.The Internet, while it may provide useful facts, has such an enormous amount of information that it impedes this selection process from being efficient. John McLaughlin, a former deputy CIA director, says â€Å"In the Cold War, we struggled to get data. Today, the problem is that there is too much data–more than we can handle. â€Å"[5] This can result in an information overload, meaning huge amounts of time and effort to be used to scan the information and select which is actually important. The difficulties in collecting information from the Internet go further than the quantitative issue.Because the information available on the Internet is what the person publishing it wants others to see, it can be dangerous because depending on this person's interests the information could be contradictory, misleading or even false, hampering the whole intelligence cycle. To avoid this, and as with any information collection, the source must be considered trustworthy, and this is always a difficult matter. On the Internet it is even more so: information is often anonymous, and meta-data (such as the circumstances surrounding the piece of information or the motivations of the person providing it) is extremely limited.Just like Jorge Luis Borges illustrates in his short story The Library of Babel, if one cannot tell what is true from what is false, the information is useless. Consequently, further sources are needed to prove the truthfulness of information and avoid being mislead. This means returning to traditional intelligence collection methods, in which case the Internet cannot be considered a source of information in itself. It can be seen, however, as inspiration for a further investigation.Moreover, the immensity of information available on the Internet incites certain types of behaviour in the information collectors, linked to their subjectiveness, that are also counter-productive for information collection. Political pressure is a potential source of error because it encourages agents to search in a certain direction, which the Internet, with its near-infinite information, is sure to justify. Firstly, it must be noted that not all information an agency looks for is necessarily available, however, the large amounts of information available on the Internet encourage people to believe such information exists.Secondly, misleading sources can exaggerate and create non-existent threats, which is sometimes what intelligence agencies are looking for in order to justify their utility. Thirdly, it is part of human behaviour to struggle to admit you are wrong, especially after investing effort in trying to prove the opposite. Once again, of all the information available on the Internet, that which proves you are in the right direction is likely to be picked, and the rest avoided, encouraging wish-fulfilment behaviour and confirmation bias.With these practical issues concerning information collected from the Internet, it can therefore be considered dangerous for it to be considered a source of information in itself. Nevertheless, it should not altogether be denied a role in information collection. The usefulness of the Internet and its place in the decision-making process If not a trustworthy source by itself, the Internet certainly contributes to a better information collection. Firstly, it directly facilitates the collection of open-source information which is then used for intelligence purposes.Such is the case, for example, with radio or television broadcasts which are now available online. In this example, it means monitors no longer have to be near the broadcast source, nor is complex equipment needed (antennas†¦ ) to obtain these broadcasts. [6] The Internet has an incredible logistical advantage, providing cheaper sources in real time all around the globe. O pen-source information is useful in providing complementary information to the confidential one. It helps determine the context and the circumstances in which the information is transmitted; it serves to â€Å"fill in the gaps†.This is essential, seen as a piece of information taken out of context makes no sense or cannot be used efficiently. Intelligence failures often come from an inability to understand â€Å"the bigger picture† or the general context of a given situation. For example, during the Vietnam war, the strategic concept of the conflict was misunderstood: the US believed it was mainly a Soviet-Chinese supported conflict and ignored the major influence of Vietnamese communists and nationalists. Moreover, information coming from he Internet is in real-time, so it can help those who collect the information assimilate new situations which arise from social or economic change for instance, and to do so quickly. It is therefore important source of collateral inf ormation, which enhances traditional information collection and enables it to be understood and interpreted. From a decision-maker's point of view, most confidential information is not available on the Internet (despite some examples which today are still very limited), which signifies traditional intelligence sources of information can by no means be given up on.The Internet is however an essential tool which must be integrated in the collection process, and in the other stages of the intelligence cycle, in order for the information provided to be pertinent. It can also serve as inspiration for further investigation, as long as its potential dangers are understood, for it is easy for decision-makers, who are under political power, to get carried away by misleading available on the Internet. Conclusion In summary, on one hand, most of the information available on the Internet is not the one which interests intelligence services because they seek mainly confidential information.On th e other hand, some of the information on the Internet hampers information collection because it can be misleading, contradictory, or even false and can lead to counter-productive behaviour from the intelligence agents. Consequently, the information available is not always the one intelligence services are looking for. In addition, there is a theoretical distinction linked to the fact information coming from intelligence must be unavailable elsewhere, which means information from the Internet cannot replace traditional intelligence.This does not imply the Internet should be avoided by intelligence services, on the contrary, it can provide essential information in complement to that obtained by intelligence services. It simply means the dangers of the Internet should be kept in the mind of decision-makers who must find the balance between these two sources of information. ———————– [1] Only the collection stage of the intelligence cycle will be discussed concerning the impact of the Internet, as this is what the statement points to. [2]http://www. usnews. om/news/national/articles/2008/09/12/spy-agencies-turn-to-newspapers-npr-and-wikipedia-for-information. [3]According to this definition, open-source intelligence is not a actually a source of intelligence, the concept open-source information in use for intelligence purposes is therefore more appropriate.

The Decline Of The Demise Of Fatherhood - 1316 Words

The Decline of Fatherhood The decline of fatherhood is the most basic, and unexpected social norm of our time. This major problem can be captured in a single statistic. In 30 years, from 1960 to 1990, the percentage of children living away from their biological father had doubled from 17% to 36%. At the turn of the century nearly 50% of children were living without their father in the household. Few researchers predicted this trend it is not widely talked about, but this simple fact has led to some of the biggest social problems that plague America today; crime and delinquency, teenage pregnancy, deteriorated educational achievement, depression, substance abuse, and children and women living in poverty. Even as calamity unfolds our views†¦show more content†¦Father involvement in schools is associated with the higher likelihood of a student getting mostly A’s. This was true for fathers in biological parent families, for stepfathers, and for fathers heading single-parent families. (Nord) The ch ildren have a harder time scoring on tests related to mathematics, reading, critical thinking when no father is present. When fathers are involved in a child s academics they are 40% less likely to repeat a grade and more likely to enjoy school and be involved in extracurricular activities. (Nord) It has been shown that kids with highly involved fathers have increased mental dexterity, increased empathy, less stereotyped sex role beliefs and greater self discipline (Abramovitch) Research also shows that when children experience high father involvement are more curious and better with problem solving. A fathers involvement seems to foster a childrens confidence to explore the world around them and to solve problems.(Pruett) When talking about dropouts, we see that 71% of them are fatherless. When we look at the total population, 19% of kids drop out of highschool. (Nord) Children from father absent homes are more likely to skip from school, more likely to be excluded from school, mo re likely to leave school at age 16, and less likely to attain academic and professional qualifications

Iago´s Facade in William Shakespeare´s Othello - 520 Words

â€Å"I am not what I am† (I i 71). In Shakespeare’s Othello no phrase describes the villainous Iago better than this. Iago hides behind the faà §ade of a loyal soldier while secretly manipulating the world around him not only for personal gain but also in order to ruin the lives of those he feels have wronged him. Even those close to Iago, such as his loyal servant Roderigo, who think they know him, are being deceived. Throughout the play Iago shows his ability to manipulate people based on their good traits, one key example being Othello. Iago ruins Othello’s life by abusing his sense of trust and exploiting his forceful nature. Iago abuses Othello’s trusting inclination in order both further his personal rank and ruin the lives of those he feels have wronged him. Trusting by nature, Othello initially refuses to see anything but the best in people, including Iago. Iago exploits this by making Othello believe things that are completely false. In Othello’s view Iago would not lie to him because he had no reason to and had never done so before. Iago does this because he feels he has been wronged when told that â€Å"[Cassio]†¦ must his lieutenant be†¦ and I his Moorship’s ancient† (I i 35).

string(116) " machines require pans under them, which need to be vacuumed regularly, and the waste oils pose a disposal problem\." Nephron technology makes a difference Engr Maliha Maisha Rahman Bannichi Enterprise limited Literature Review:TBN: In short, a TBN (total base number) measures the amount of active additive left in a sample of oil. The TBN of a used oil can aid the user in determining how much reserve additive the oil has left to neutralize acids. The lower the TBN reading, the less active additive the oil has left. We will write a custom essay sample on Nephron Technology for Lube Oil or any similar topic only for you Order Now Oil’s function is to lubricate, clean, and cool the engine. Additives are added to the oil to enhance those functions. Viscosity: Technically, viscosity is defined as resistance to flow. Commonly though, we think of it as an oil’s thickness. To be more specific, it is the thickness of an oil at a given temperature. The viscosity of an oil could be reported at any temperature, but to standardize things, most laboratories report either a low temp (100F or 40C) or a high temp (210F or 100C) and stick with either SUS or cSt. The standardized temperature reading allows us to compare apples to apples for judging the thickness of the oil. Single Grade ; Multi Grade Viscosity: today since most gas- or diesel-engine manufacturers recommend multi-grades. At operating temperature, a straight weight performs just as well as a multi-viscosity oil, and there is nothing wrong with using a straight weight. It’s just a simpler form of oil. Some diesel fleets still use straight weights, as do about half the piston aircraft operators. The difference between multi-grade and straight-weight oil is simply the addition of a viscosity improving (VI) additive. The most common grade of automotive oil in use today is the 5W/30, which is a mineral oil refined with VI additives that leave it reading as an SAE 5W viscosity when cold, yet an SAE 30W when hot (210F). The advantage to the multi-weight is that when starting the engine, the multi-viscosity oil (with its thickness of an SAE 5W when cold), allows the engine to spin over more easily. The most common diesel use oil is 15W/40. It is an SAE 15W oil with a VI additive that leaves it the thickness of an SAE 40 weight at operating temperature. What makes an oil a diesel-use oil (rather than automotive-use) is the level of additives used. Diesels require heavier levels of dispersant and anti-wear additives. These heavier additive levels are objectionable for automotive engines since they may interfere with the emission controls andated by the EPA. Need To Choose the Proper Viscosity: We are seeing that trend for newer engines, for which the recommended grade is getting progressively lighter. The common 10W/30 has become a 5W/30, and some manufacturers even recommend 5W/20 oil. On the other hand, we can’t see (in oil analysis) where it hurts anything to run heavier 10W/30s or even 10W/4 0s in modern automotive engines. The heavier oils provide more bearing film, and that’s important at the lower end. If your oil is too light, the bearing metals can increase. If the oil is too heavy, the upper end metals can increase. The trick is to find the right viscosity for your particular engine, which is why we suggest following the manufacturer’s recommendation. Changes in Viscosity/Adding additives? Then the Result Comes: Adding anything foreign to your oil can change its viscosity. Some types of after-market oil additives cause a quite high viscosity at operating temperature. While an additive might improve bearing wear, it can often cause poorer upper-end wear. We don’t recommend any type of after-market additives. Other changes to viscosity can result from contamination of the oil. Moisture and fuel can both cause the viscosity to increase or decrease, depending on the contaminant and how long it has been present in the oil. Antifreeze often increases an oil’s viscosity. Exposure to excessive heat (leaving the oil in use too long, engine overheating) can also increase viscosity. When your oil’s viscosity comes back as either lower or higher than the â€Å"Should Be† range, something is causing it. If the high/low viscosity is hurting wear, the key is to find out what it is and repair your engine or adjust your driving habits accordingly, to correct the viscosity and optimize your engine’s efficiency. If you decide to use a different viscosity oil than what the manufacturer recommends, you might want to use oil analysis while you are experimenting. Your wear data doesn’t lie. People selling oils and additives may be sincere, but they don’t have to live with the results. They simply smile a lot on the way to the bank. MoistureProblems: Industrial oils run â€Å"cold† compared to other (such as automotive-use) oils, and they tend to accumulate moisture. The moisture comes from humidity in the air, or in some cases, it’s directly introduced to the oil from coolants and related systems. Moisture affects the lubricity of the oil, decreasing its effectiveness. Moisture in the oil can cause a variety of problems, such as poorly running hydraulic rams, machine sizing, and chatter. Another negative effect of moisture in oil is acidity. Oil, by its molecular nature, cannot become an acid. But there is always a little moisture present in oils operating at relatively cool temperatures, and that moisture can turn acidic. Acids in a machine’s oil sump will corrosively attack internal parts not only the metallic parts, but the seals as well. Corroded valves become ineffective. Many headaches in a machine’s operation can be directly attributed to oil condition. Though oils do not respond to the pH test, there is a neutralization test called Total Acid Number (TAN) that can easily spot oil that is becoming problematic. AbrasionProblems Industrial oil becomes abrasive from wear metals, abrasive dirt, and particle contamination. The most serious result of abrasive oil is the detrimental effect it has on seals. Machine seals are lubricated by the system’s oil, and they will last a long time if the oils are maintained effectively. If they are not maintained properly, the seals will degrade and cause leakage. Leaking machines require pans under them, which need to be vacuumed regularly, and the waste oils pose a disposal problem. You read "Nephron Technology for Lube Oil" in category "Essay examples" Fresh oil is purchased needlessly, running up maintenance costs. Machines that leak oil also run the risk of being run low on oil and having improper oils used as replacement. All these expensive problems can be eliminated by keeping machine oils in serviceable condition. WhatAboutFilteringOil? Many industrial operations hire filtration companies to filter insolubles and abrasive contaminants from their oil. Some plants operate their own filtration equipment. Filtering oil that’s currently in use is a good idea, and it helps companies avoid needlessly purchasing virgin oil products, but it has limits. Oil that is filtered too many times can contain damaged additives. If the additives are damaged, the oil can’t function effectively: the oil loses lubricity and becomes oxidized. There is a point at which the additives either need to be restored or the oil needs to be replaced, and oil analysis is useful in determining this point. It can also help to rate the effectiveness of a company’s filtration program. Not all wear metals and abrasive contaminants can be filtered out of the oil; they tend to accumulate and eventually reach levels that leave the oil unserviceable. A test known as the ISO Cleanliness Code (also called a â€Å"Particle Count†) can be used to rate the cleanliness of an oil sample. This test also shows the effectiveness of the machine’s in-line oil filtration. Insolubles test : The insolubles test measures the total insoluble materials in an oil sample, that is, all solid or liquid materials that are not soluble (won’t mix) in oil. Virgin oil shouldn’t have any insoluble materials in it. When it occasionally does, the most we normally find is a trace level. The insolubles in virgin oil are from the normal oxidation process of the oil, which leaves free carbon in suspension when oxygen forms with hydrogen (oil is a hydrocarbon). The insolubles test is a centrifuge method. A measured volume of oil is mixed with a heated solvent, agitated, and spun at high speed. Insoluble materials collect at the bottom of a tapered glass tube and can then be quantified. The insolubles test is a fair measure of how fast the oil is oxidizing and receiving contaminants, and how effectively the system’s oil filtration is functioning. Industrial oil normally contains very low insolubles due to the few and relatively mild heat cycles the oil experiences (heat cycles accelerate the oil’s normal tendency to oxidize). Further, oil filtration on industrial machines may filter particles as small as 2 to 10 microns, keeping the oil pristine for a very long time, often years. Automotive and aircraft oils however, suffer the most difficult environmental problems of all types of oils we analyze. They regularly receive blow-by products from the combustion process. They suffer extreme heat cycles. Any contaminant in the oil will accelerate the oxidation process, causing insoluble materials to increase. Engine oil needs to be changed regularly due to all of the above. Excessive insolubles can form in an engine oil if the oil: is running hot, is receiving more than a normal amount of contamination, is suffering more (or more severe) heat cycles than is normal, is being run longer than a typical use cycle, or, on the other side of the coin, if oil filtration is marginal or relatively ineffective. If we found no contamination in your oil and your change intervals are normal, we often mention a problem at oil filtration as a possible cause of higher insolubles. Insolubles may be forming because your oil change interval is too long for the condition of the engine. Your oil filter may be inferior. It is possible the oil filter bypass valve has relived if the filter is becoming restricted. The filter system bypass may also open upon unusually cold starts when the oil is too thick to pass through the filter media. Once the bypass relieves, the filter is effectively out of the system.

This is the main reason why this system was selected for this experiment. Those particles of the lube oil that do deteriorate via oxidation are so small when using the filtration system of the nephron system that they can be disregarded. The particles of lube oil that is lost when using lube oil are those that are oxidized, evaporated or destroyed by high temperature. In other words, the ratio of molecules with large molecular weight grows as time passes using the lube oil. This is because the molecules which are smaller are more susceptible to heat and are therefore lost more easily. The oil begins to resemble the properties of the high grade naturally occurring lube oil in such location as bright stock. The actual burning proof load of this oil is approximately 25% better than that of new oil. For these reasons it is natural to use nephron system. The more time proceeds it gets more viscous.

Question: Desceibe about the digital comics: Creating a pathway for autistic children to connect through a superhero narrative. Answer: Introduction Autism Spectrum Disorder (ASD) or autism is a complex developmental disability. It is detected in childhood and impairs the communication ability of an individual (Thompson, 2013). It is characterized by certain set of behaviors and is called as spectrum condition that affect each child differently and to a varying degree. In United Kingdom autism occurs in every 1 in 68 births (ADDM autism prevalence report, 2014). It has been estimated by autism society that the US cost for autism annually is $90 billion. Autistic children face bewildering and irrational challenges in the world. They are expected to cope with this challenges which results in high level of anxiety, stress and behaviors. Dealing with such behavior becomes difficult for people around them and offers a significant challenge to the health care service providers, educators, and other professionals such as social workers, language therapists (Park et al., 2012). Some of such behaviors include difficulty with executive fun ctioning, poor motor skills and sensory sensitivities, difficulty making eye contact, delayed learning of language, persistent fixation on particular object, lack of ability to socialize with peers, distorted speech and language. It implies the need of a practical approach to understand the behavior of the autistic children and provide necessary support (Radley et al., 2015). According to Burn Durran, (2007), children do not outgrow autism but it is treatable through early diagnosis and intervention. Recently there is an increasing popularity of superhero narratives representing the both the embodied and social experiences of autistic children such as the Super, Circling Normal. These emerging tools have the ability to breach the wall of ignorance build up around the children with autism and generate greater public awareness of such disabilities. The unique characteristics of these comic strips are to promote the rights of autism children, demonstrate the impact of autism on the fa milies and empower children to become successful in their environment. In this assignment we will deal with how digital comics acts as a pathway for autistic children to relate with their cognitive disability and breaks the confining cultural framework through which some people are overlooked and other are seen. Further, the paper also discusses the Piagets theory of cognitive development and children learning. It explains how this theory can help teachers to tackle autistic children and improve their learning skills. A thorough literature review is performed to support the facts in the paper and lastly conclusion is drawn based on the discussion. Cognitive models of autism Autism mainly consists of three primary symptoms which involve behavioral, social and communication aspects. Several theories have been developed to explain the dilemma related to cognitive dysfunction of autism (Park et al., 2012). The mind deficit theory refers to the ability of children for imagination, beliefs, desires, and emotions and makes other mental states. Autistic children have a cognitive deficit as they cannot understand others thoughts (Locke, 2005). As per the executive functioning theory children mind involve in planning, impulse control, mental flexibility, inhibition, working memory and monitoring of action. Autistic children have executive dysfunction which is reflected in their repetitive and restricted behavior. Their poor social connection appears to be defect in cognitive shifting an important factor of executive function (Cohn, 2013). The persistency in particular behavior and focusing on specific parts of the objects seen in autistic children can be explaine d through weak central coherence theory which refers to inability of the child to see broader side of things or context (Simmons et al., 2014). According to Piagets two factor theory related to figurative and operative functions, autistic children have a defect in sensory motor neurons resulting in arrest of operative functions while having normal figurative functions (Marion et al., 2016). Thus higher-level of figurative, social skills fail to develop completely due to this arrest in children. However, no cognitive theory so far could provide a complete picture of autism development and has only explained the static cognitive impairment (Hall, 2012). How does superhero narratives connect with autistic children Comics are an art form of communicating various messages in an artistic way using outlandish fantasy and absurd characters (Gresh Weinberg, 2003). Since the last couple of centuries they have been playing an important role in the life of children and have been embraced by academia as well (Saraceni, 2000). Recently comics are developed with characters playing the role depicting particular disability. The advent of digital comics have has revolutions this art work. With the growing demand of tablets and smartphones, usage as well as desktop screen reading comics are increasing released in digital format (Rutter Schopler, 2012). For example, the Marvel comics offer a subscription service for users to read online comics from Marvels history. According to the survey reports Schreibman et al., (2015) most girls get bored with princess movies but never with superhero narratives. Most of these girls have in their opinion that a superhero will always win in a fight against a princess. Superheroes are highly engrossed in the childhood culture. According to Radley et al., (2014) the most common thing about superheroes right from masked villain to caped crusader that all the children love irrespective of being autistic is their power. It is their power to fly, read minds, shoot fire, throw cars and fighting skills. According to the research conducted by Justin Martin the psychology professor at Whitworth University, it is not just the power that makes attract these kids towards superheroes rather the pursuit of justice (Wood, 2015). Gardner, (2013) demonstrated that justice is the first thing that shrine when looking at superheroes. Kids mostly like the superheroes self-sacrifice and hope in the face of insurmountable odds. As p er martin, the powerful impetus for change for young autistic children is the unique origin of each superhero story. For example, Peter Parker receiving unique powers after being bitten by radioactive spider and later uses these powers for personal benefits and turning into Spider-Man. He further sinks in the message that great power brings along a great responsibility. Piaget, (2013) studied attitudes of kids towards superhero comics and learned from a 7 year old girl that she personally preferred Scarlet Witch because of her moral arc. Superheroes such Batman, Spider-Man and Superman are extremely popular among children irrespective of their growth environment (Wilson, 2005). Curiosity and imagination are the key aspects of growth of every child and they imitate adults and talk to strangers in order to show their fascination with things that are beyond their realm of possibilities. Children need their moral imagination to be healthy and refined for decision-making. The components of this moral imagination are the ability to view ones life as narrative and utilization of moral perception (Burn Durran, 2007). The story of Guardians of the Galaxy has inspired the autistic children to be like a superhero in the movie (Inhelder et al., 2014). Children with autism who cannot do metaphors can relate themselves with Drax the Destroyer in the movie who also cannot comprehend metaphors. Superhero comics with characters playing the role of an autistic individual or having any other disability help autistic children to reflec t on their life experiences, and allow them to decide the important factors of their life (Autism Society, 2016). The autistic children enjoy comics because they can relate themselves with the characters in the story, which allows them to reconstruct their identity. Therefore, superheroes can be a great moral-teaching tool for teachers and parents (Wilson, 2005). Children believing in a just world are known to find learning a positive experience, trust their teachers and succeed in school. Martin believes that superhero narratives are more desired among autistic children for whom the world appears to be filled with terror. Among these children, superhero narratives become a personal treasure. Autistic children watching Batman helping the city of Gotham and neighbors on the street learn empathy and tend to make positive connections around them (Autism Speak, 2016). These superhero narratives also introduce these children with interpersonal superpowers such as differentiating between right and wrong, truth and lies and other emotions (Bainbridge, 2015). Therefore, the justice factor emphasized by the superheroes and its relationship with childrens beliefs in just world has been recognized to serve as an educational function for autistic children t o enhance their moral development. Digital comics are a source of motivation for impressionable young audience and teach autistic children who have low self-esteem and confidence that they too can be heroes (Martin, 2007). It demonstrates the world that anything can be done by having a right mindset and a pure heart. It sends a message that heroic mindset does not pay heed to perceived flaws, poor medical condition and disability (Burn Durran, 2007). These digital comics illustrate that in order to be a hero one does not need to mould their true nature to appear in certain way rather can be a true self. The superhero comics act as a tool to instill belief among these children in that just world (Rubin Livesay, 2006). Superheroes fill a void in the life of autistic children by instilling a hope even in darkest hour. These believe act as a catalyst for change on a micro-level and in addition, it have a trickledown effect on the kids and adults. Various characters in superhero narratives such as (Seth in Circling Norma l or Drax in Guardians of Galaxy) have a given a confidence to millions of mentally challenged children that they can uphold responsibility and wield great power (Bainbridge, 2015). These children too can now indulge in fantasy like other normal kids and dream of themselves developing and showing heroic spirit. Autistic children relating themselves with superhero characters in comic movie and stories indicate the positive power of superhero movies in enhancing personal attachment where kids can take a piece of action to their home calling their own (NAS, 2016). Recently, it has been observed that superheroes not only appeal and connect with kids in comics rather their ability has seeped into the classroom as well. Some researchers have found success in creating social skills training for autistic children using superhero themes and is highlighted in (Wilson, 2005). According to Piaget, (2015), most autistic children have trouble relating socially with their peers and simply teaching such social skills is not enough for them. It implies that a program that resonates with autistic children is required to be developed. Therefore, superheroes was recognized as a sticky factor that is difficult for autistic children to get out of their head. Hence, Jenson the professor of educational psychology at Utah University and his team have developed a superheroes social skills program for teaching autistic children. This multimedia program uses different characters such as Scooter, Iron Man, to teach different lessons. The results of this program were fo und effective. Educators of autistic children are geared towards their moral development through powerful comic characters rather than focusing on the test scores (Bainbridge, 2015). The aim of developing such classroom is to foster positivity and practicality in children and help them lead one such life as depicted in superhero narratives. Teachers can use a childs fascination with superheroes to explain them the way of behaving inside and outside the classroom. Park et al., (2012) suggested that educators can monitor students superhero play and use the characters in the play to help students differentiate between the negative and positive behavior, cooperation and the ways of conflict resolution. However, teachers must lay little emphasize upon the dark side of these superheroes and instill in minds of children that violence is used as last resort. For example, Spider-Man responds only to situation that are morally important and use violence only when they recognize that not appre hending the villains may harm well being of others. Therefore, it is the responsibility of the educators to facilitate development of autistic children using superhero tool (Inhelder et al., 2012). Burn Durran, (2007) highlighted a fact that the influence of superhero comics on autistic children has larger implications for society. For example Comics such as The Ride Together has well demonstrated that how autism becomes part of the familys collective identity. In this comic story, Paul and Judy Karsaik describes their experiences of growing up with their brother, who is autistic. In one of the comic strip Paul narrated that how their autistic brother loudly applauded and behaved unusually while watching a movie and how he was embarrassed. In Circling Normal Montague-Reyes has based her strips about Seth who was diagnosed with autism at age of two and depicted his emotional experiences such as aggression, anxiety. Similarly, X-Men has motivated large number of children as he demonstrated love and acceptance through his work towards uniting humans despite their individual differences by internalizing his professors teaching (Gresh Weinberg, 2003). These comic strips have addre ssed the debate topic whether to accept or normalize children (Locke, 2005). These comics help autistic children to meet the standards set by their adults being inspired by the mighty image of superhero coming out victorious from unfortunate of circumstances (Rubin Livesay, 2006). The comic strip conversation has been recognized to improve the autistic childrens social skills and reduce the signs of loneliness. Autistic children fail to express their thoughts as a result of which they experience isolation from others. These comics give them a sigh of relief making them believe that their behavior is normal and assure them that they can also live happy life (Rutter Schopler, 2012). The literature review has showed that autistic children are more engaged with friends and peers after applying superheroes social skills programs or interventions (Radley, Hanglein, Arak, 2016). This has further led to positive outcomes and improved language skills. These comics play an important role a s they have become a form of academic studies which aims to incorporate the fullness of experience of autistic children (Burn Durran, 2007). The comics are powerful in demonstrating the emotional, social, motor, sensory, and cognitive factors affecting an individual, therefore, avoiding the person being reduced to stereotype of one particular facet of his or her identity. These superhero narratives assist society to accept such people and embrace them inspite of the differences (Rutter Schopler, 2012). Teaching programs in classrooms include assigning children with roles of different superhero characters to play help resolve various conflicts when for example, assigning same superhero character to two children, and debated over team goals (Piaget, 2013). When individual roles are assigned to the children, it helps them to resolve issues of gender equity, for example some girls preferred X-Men than other superheroes (McLoud, 2000). The reason behind such preferences being the fact that the unlike other superhero groups, X-Men group represents female members (Rubin Livesay, 2006). These superheroes are agents of social change as they fight for justice and equality. Use of superheroes in social skills training program for autistic children by Jenson has helped such children to perform their work even when others disagree with them. They tend to align themselves with the prosocial behavior demonstrated by their superheroes (Inhelder, Sinclair Bovet, 2014). Conclusively, superhero nar ratives are creating a pathway for academic, moral and social development of autistic children. Educators must understand as to why a particular child fascinate about a specific superhero character and use this fascination to foster their growth and similar behavior in them (Burn Durran, 2007). It implies for the teachers that they should incorporate favorite superhero character of children into play activities and lessons to facilitate their learning process and ensure that the influence is positive and educational (Piaget, 2015). Various schools have used Manga to teach chemistry and biology to the students and results showed that children have found these strategy interesting and has improved the learning of complex subject (Radley, Hanglein Arak, 2016). Educators can incorporate the Piagets theory of children learning to improve learning outcomes of autistic children. As per Piagets experimental observations with children of different age, it is necessary that a teacher should mainly focus on the thinking process of an autistic child (Burn Durran, 2007). While checking answers teachers must analyze that what thought process made a student to reach particular answer. According to Piagets experiences with children, positive learning outcomes are built on their cognitive functions and such experiences can be provided to the students only when the teacher appreciates childrens basis of reaching a conclusion (Piaget, 2013). Piaget emphasize on providing an environment with conditions of inventions for children rather than giving them a readymade knowledge (Martin, 2007). This will ensure promotion of childrens self initiate and active involvement spontaneously. Further most teachers in UK and US intend to speed up the development and le arning process (Rubin Livesay, 2006). However, in piagetian classroom, children have a window for true cognitive understanding. It implies for the teachers that premature teaching should be avoided as it only leads to superficial acceptance of the adult formulas. Further, education programs based on Piagets theory includes acceptance of the individual differences in developmental progress (Tatalovic, 2009). Teachers must take into account that each child has different rate of cognitive development and therefore arrange classroom activities accordingly including small groups of people rather than involving the total class. Further, the teacher must regularly assess the progress of individual child in terms of their previous course of development. Educators must avoid taking into consideration the normative standards provided by the performance of same age peers (Inhelder, Sinclair Bovet, 2014). Therefore, keeping in view the theories of Piaget, some of the promising strategies for teaching autistic children include teaching plan that is abstract, concrete and well structured as autistic children cannot handle complex stuff (Martin, 2007). Teachers should focus on scaffold language support by segregating children according to language level and use more simple language while teaching lesson (Rubin Livesay, 2006). Teachers should ensure developing a fun and nurturing classroom environment that will increase self-motivation by fostering self-esteem and confidence. More classrooms in US for autistics are decorated with colorful funny pictures that most children fascinate about. These also include comic story superheroes to motivate them (Wilson, 2005). The strategies also include increasing social initiations, use of role-play and modeling to teach social skills. It also includes use of behavior charts, and reinforce particular behavior with stars to reduce other interfering b ehaviors (Wilson, 2005). As per the Piagets theory children need to interact with materials and people around them to suffice their curiosity (Tatalovic, 2009). These strategies also include promotion of skill generalization by promoting peer involvement, involving parents and multiple trainers. Children should be allowed to practice skills in a natural setting providing multiple opportunities (Tatalovic, 2009). There must be regular evaluating system to track the progress and provide students with home assignments in addition to practical sessions (Burn Durran, 2007). The Social skills training program by Jenson utilize similar strategies and have come with positive outcomes. The key aspect of these interventions is the need to focus on one-on-one direct teaching by truly creating a social situation involving interaction with varied people. According to Thompson, (2013) partnership and cooperation can be encouraged by involving children in group activities (Schreibman et al., 2015 ). The most important aspect of teaching social skills to autistic children is to promote childrens learning by explaining the relevance of a particular skill. This will help children stuck in learning a skill (Park et al., 2012). The sum of these strategies is also called as Pivotal Response Treatment (Park et al., 2012). Schreibman et al., (2015) highlighted that the social story method is effective for helping a child with autism to understand, respond and meet the expected needs. The stories of superheroes or any other comic strip conversation help children to learn and behave appropriately and have significantly improved their inclusion in classroom activities. Further, teachers support the autistic children to communicate through computer or typewriter. Overall the autistic children need learning environment that is conducive to the unique needs of children and it has been observed recently that incorporating superhero narratives in every stage of child development have helped to enhance the learning experience of autistic children and invigorate the educators working in such supportive learning environment. Conclusion The correct approach for dealing with autistic children is still a mystery for the teachers and physicians. Learning the autism and teaching theories may help care providers to deduce correct approach and steps for building up the knowledge for autistic children. Digital comics are useful in being an empathetic representation of autism where they can highlight both the values of difference and the ordinariness of aberration. Comics promote social change by advocating for human rights for people with autism. Colorful comics representing autism spectrum allow family members to develop strategies to help their autistic kids to strive to be successful in their environment and in life. Superhero narratives are creating a pathway for academic, moral and social development of autistic children. Comics are excellent in conveying the experiences of the disability in a lived context because of the ability to depict both the spatial and temporal relationships simultaneously. Majority of childre n and adults embraces comics as they provide a means to realize our own life by seeing into experiences of the characters by the use of thought bubbles, jagged lines for demonstrating anxiety, sound effects and relative fullness. Comic books superheroes characters are efficient in raising public awareness about disability issues. Consequently, it leads to personal empowerment, promote cultural understanding, and raise activism across cultures. Diverse modes of communication are required to understand autism that will assist humanities scholars involved in the studies of disability to incorporate different perspectives in their work. Studies of comics paint a picture of multiple embodied and cognitive style of living. They emphasize the importance of nonverbal form of expression, for example some comics portray the powerful communicativeness of silence. The literature review implies for the teachers that it is not difficult to teach the students with autism or convey their messages. Educators, therapists and the general practioners can use the theories of Piagets cognitive development and the various aspects of superhero narratives to develop an effective teaching plan to meet their educational and development needs. The speech and language therapists too can use some of these components to enhance their language skills. The effectiveness of media teaching has been explored by several researchers and thereby it is recommended to all the educators, therapists and teachers of autistic children for keeping latest technology and childrens fascination in mind while delivering any services.
