Filtration Centrifugation Free Essays

FILTRATION â€Å"Filtration might be characterized as a procedure of division of solids from a liquid by going the equivalent through a permeable medium that holds the solids, however permits the liquid to go through. † The suspension to be separated is known as slurry. The permeable medium used to hold the solids is known as channel medium. We will compose a custom paper test on Filtration Centrifugation or then again any comparative theme just for you Request Now The aggregated solids on the channel are alluded to as channel cake, while the reasonable fluid going through the channel is filtrate. At the point when solids are available in a low fixation I. e. , not surpassing 1. 0% w/v, the procedure of its partition from fluid is called ‘clarification’. Procedure of filtration: The filtration activity is appeared beneath in the figure * The pores of the channel medium are littler than the size of the particles to be isolated. * Filter mechanism (for eg: channel paper or muslin material) is set on a help (a strainer). * When slurry (feed) is ignored the channel medium, the liquid moves through the channel medium by uprightness of a weight differential over the channel. * Gravity is following up on the fluid section. In this way, solids are caught on the outside of the channel medium Figure 1: filtration Once the primer layer of particles is stored, further filtration is realized wherein the channel medium serves just as a help. * The channel will work effectively simply after an underlying store. * After a specific purpose of time, the opposition offered by the channel cake is high that basically filtration is halted. Thus, a positive weight is applied on the channel cake (upstream) or negative weight (attractions) is applied underne ath the channel medium (downstream). Variables influencing the pace of filtration: The pace of filtration which relies upon different components can be composed as: Rate of filtration = Area of channel X Pressure contrast Viscosity X Resistance of cake and channel The pace of filtration relies upon the accompanying variables: 1. Weight: * The pace of filtration of fluid is straightforwardly relative to the weight distinction between the ‘filter medium’ and ‘filter cake’. * Thus, the pace of filtration can be expanded by applying pressure on the fluid being separated or by diminishing the weight underneath the channel. 2. Consistency: * The pace of filtration is conversely relative to the thickness of the fluid experiencing filtration. Fluids which are gooey get sifted gradually in contrast with fluids with low thickness. * Reduction of thickness of a fluid by raising the temperature is much of the time done so as to quicken filtration. eg: syrups are all the more immediately sifted when hot and cold. 3. Surface territory of channel media: * The pace of filtration is legitimately corresponding to the surface region of channel media. * Pleating the channel paper or utilizing a fluted pipe expands the powerful surface territory of channel paper for filtration. Channel press likewise takes a shot at a similar guideline. 4. Temperature of fluid to be sifted: Temperature assumes a significant job in the pace of filtration. * Viscosity is decreased by an ascent in temperature and the filtration of thick oils, syrups and so on is regularly quickened by sifting them while they are as yet hot. 5. Molecule size: * The pace of filtration is straightforwardly corresponding to the molecule size of the strong to be expelled. * It is simpler to channel a fluid having coarse particles than that having finely separated particles on the grounds that coarse sifting medium can be utilized to channel fluid having coarse and henceforth it expands the pace of filtration. Along these lines before filtration, some technique ought to be embrac ed to agglomerate the finely isolated particles into coarse particles or to expand the molecule size by precipitation. 6. Pore size of channel media: * The pace of filtration is straightforwardly relative to the pore size of the channel media. * The fluid having coarse particles requires a coarse sifting media to evacuate them. Along these lines, the pace of filtration is expanded when a coarse channel medium is utilized for filtration. 7. Thickness of cake: * The pace of filtration is conversely corresponding to the thickness of the channel cake framed during the procedure of filtration. As the filtration procedure continues, the strong particles begin keeping on the channel medium, and accordingly, it expands the thickness of the cake and diminishes the pace of filtration. 8. Nature of the strong material: * The pace of filtration is straightforwardly relative to the porosity of the channel cake. * The porosity of the channel cake relies upon the idea of the strong particles to be expelled from the fluid. * Filter helps are some of the time added to the separating fluid to make a permeable cake Theories of filtration The progression of a fluid careful a channel adheres to the fundamental guidelines that oversee the progression of any fluid through the medium contribution obstruction. The pace of stream might be communicated as: Driving power Rate = â€â€â€â€â€â€â€ (condition 1) Resistance The pace of filtration might be communicated as volume (lit) per unit time (dv/dt). The main impetus is the weight differential between the upstream and downstream of the channel. The opposition isn't consistent. It increments with an expansion in the testimony of solids on the channel medium. Accordingly filtration is anything but a consistent state. The pace of stream will be most prominent toward the start of the filtration procedure, since the opposition is least. When the channel cake is framed, its surface goes about as channel medium and solids constantly store adding to the thickness of the cake. The protection from stream is identified with a few factors as referenced beneath. Length of vessels Resistance to development = â€â€â€â€â€â€â€â€â€â€â€â€â€â€â€â€â€â€â€â€ Poiseuille’s Equation: Poiseuille’s thought about that filtration is like the smooth out progression of a fluid under tension through vessels. Poiseuille’s condition is ? pr4 V = â€â€â€â€â€â€ 8L? Where, V= pace of stream, I. e. , volume of fluid streaming in unit time, m3/s(1/s) p = pressure contrast over the channel, dad r = range of the fine in the channel bed, m L = thickness of the channel cake (narrow length), m = consistency of filtrate, dad s If the cake is made out of a massive mass of particles and the fluid moves through the interstices (relate to an assortment of slim cylinders), at that point the progression of fluids through these might be communicated by poiseulle’s condition. Darcy’s Equation: Poiseuille’s law expect that the vessels found in the channel are exceptionally sporadic and nonuniform. Consequently, if the length of a hairlike is taken as the thickness of the bed, revision factor for range is applied so the rate condition is fir mly approximated and rearranged. The factor affecting the pace of filtration has been joined into a condition by Darcy, which is: KA P V = â€â€â€â€â€â€â€ ? L Where, K = penetrability coefficient of the cake, m2 A = surface territory of the permeable bed (channel medium), m2 p = pressure contrast over the channel, dad L = thickness of the channel cake (fine length), m ? = consistency of filtrate, dad s The term K relies upon the qualities of the cake, for example, porosity, surface region and compressibility. Porousness might be characterized quantitatively as the stream pace of a fluid of unit consistency over a unit region of cake having unit thickness under a tension inclination of solidarity. This model relates not exclusively to channel beds or cakes yet additionally applies to different kinds of profundity channel. Hardware is substantial for fluids moving through sand, glass dabs and different permeable media. Darcy’s condition is additionally changed by including qualities of K by Kozeny-Carman. Kozeny-Carman Equation: Poiseuille’s condition is made appropriate to permeable bed, in view of a hairlike sort structure by including extra boundaries. In this manner the resultant condition, which is generally utilized for filtration is Konzeny-Carman condition. A p ? 3 ?S2 KL (1-? )2 V = â€â€ â€â€- â€â€â€ Where, ? = porosity of the cake (bed) S = explicit surface region of the particles containing the cake, m2/m3 K = Konzeny steady p = pressure contrast over the channel, dad L = thickness of the channel cake (slender length), m ? = thickness of filtrate, dad s The Konzeny steady is typically taken as 5. The impact of compressibility of the cake on stream rate can be acknowledged from condition (1), since the stream rate is relative to ? 3/(1-? )2. A 10 percent change in porosity can create just about 3-overlay change motel V. Impediments of Kozeny Carman condition: Kozeny Carman condition doesn't assess the way that the profundity of the granular bed is lesser than the real way navigated by the liquid. The genuine way isn't straight all through the bed, however it is twisted or convoluted Mechanisms of filtration: The system whereby particles are held by a channel is critical just in the underlying phases of filtration. A portion of the systems are: Straining: Similar to sieving I. e. , the particles of bigger size can't go through the littler pore size of the channel medium. Impingement: Solids having energy move along the way of smooth out stream and strike (encroach) the channel medium. Consequently, the solids are held on the channel medium. Ensnarement: Particles become weaved (trapped) in the mass of filaments (of fabric with a fine furry surface or permeable felt) because of littler size of particles than the pore size. In this way the solids are held on the channel medium. Alluring powers: Solids are held on the channel medium because of appealing powers among particles and channel medium, as in the event of electrostatic

Fresh Water Distillate Pump

New Water Distillate Pump Presentation . There was MOD vessel on the port and this vessel required a new water for the 50 group on the boat. So I need to make a framework to deliver new water on that transport. In any case, the issue is that the boat is at port and there is part of waste present in the port ocean water, for example, natural waste which contain essentially trash ,untreated sewage which can release straightforwardly or by implication in the sea.treaces of substantial metals additionally present mercury,cadmium,,chromium these overwhelming metals are risky to wellbeing and furthermore to the environment.heavy metals, for example, zinc and lead may causes consumption .close to of these there was sone anthropogenic wellspring of waste present which are recorded beneath. Mining effluents Residential effluents Mechanical effluents Transportation exercises including those of mechanized vessels and kayaks. Manures pesticides Climatic sources, for example, gas flaring, cremation of residential waste masculine trash. Oil enterprises exercises. As indicated by uk water guideline the perctange of some substantial metals must be at sure level Figuring Before picking any generator I need to figure the water which satisfy the necessity of 50 people. In a boat one individual can MAXIUM 600 to 800 liters for every day. An individual can utilize the new water for washing garments, washing utensils, wash room, drinking, cooking, washing, and so forth. On the off chance that we figure the new water for the 50 people is㠢â‚ ¬Ã¢ ¦Ã£ ¢Ã¢â€š ¬Ã¢ ¦Ã£ ¢Ã¢â€š ¬Ã¢ ¦! 800*50= 40000 liters for every day so I need to picked a framework which is skilled for the creation of minim 40000 liter for each day Kinds OF FREH WATER GENERATOR in a productive motor, just about portion of the warmth in the fuel is changed over into helpful work a portion of the Heat vitality is lost in the cooling frameworks and fumes gas. be that as it may, a portion of the warmth lost is recuperated . the Modern profoundly pressure charged motors have a lot of vitality in rummage air cooling wateer and this can be give as the wellspring of warming to the bunkering .an other wellspring of warmth is coat water cooling and it likewise contain significant measure of warmth and this warmth can be recuperated in the new water evaporator framework which work at the weight giving a comparing immersion temperature fo water bring down the coat water entering in to the warming medium .gasses broke up when water is warmed to its immersion temperature. There are two techniques for creating new water, 1.Reverse Osmosis 2. refining. is commonly utilized were enormous amounts of generally low quality water is required. Run of the mill instances of water delivered are; Treatment Absolute Hardness Calcium Hardness Silica Sodium Chloride TDS Ocean Water 250 200 14 15000 15000 Evaporator Turn around Osmosis 20 5 After Demineraliser 0 Follow . Refining The most usually use freshwater age is evaporative refining, which utilizes motor coat cooling water or steam heat from fumes or gas terminated boilers to dissipate ocean water, which is then dense into new water. Vanishing distillers comes in two fundamental structures, 1.multistage glimmer 2 multi impact evaporators. Straightforward single impact evaporator The framework above shows an evaporator normally warmed by Main Engine Jacket water with intends to flexibly steam when the motor is closed down Single and multi stage tube refining was one of the early kinds of new water age. It utilizes heat going through lowered curls or cylinder groups submerged in ocean water to deliver the distillate, which when dense turns into the new water. Single Stage Flash Evaporator streak evapourator it comprise of two sections 1.condensor 2.evaporator by and large the warming technique utilized is primary motor warmth or by warming oil ordinarily the water bubbles at 100 degree. In any case, in the freshwater generator the water inside the framework generally bubbled at 60 to 70 degree. By utilizing ejector or edecutor.basically an elective plan to the shell evaporator is the blaze evaporator were warming happens remotely, the hot salt water enters the low weight chamber into a weir where a portion of the water flashes off. Water flooding the weir is either out or given to a subsequent stage. Multi stage units with each stage kept up at a lower pressure permit improved effectiveness and high yields. to check the level of salt salinoemetre is utilized. its is critical to utilize salinometere in such a case that the level of salt in water turned out to be high then it can recognize it and raised the alert Multi Stage Flash Evaporator streak stream diagramr in this procedure we utilize two dissipation organizes so as to show signs of improvement ordinary multi stage streak framework depends on preheating of a pressurized ocean water stream, or all the more ordinarily a reuse saline solution stream to which the feed ocean water is included the stream is warmed in the warmth input area salt water warmer. Twofold stage FWG is like the single stage FWG, the main distinction being that the entire single stage process is rehashed twice in 2-phase generator From here the reuse stream is passed into the primary phase of a progression of glimmer chambers. Here the weight is discharged, allowing a bit of the saline solution stream to glimmer to frame without salt fume which is dense to give the new water. In gathering the fume emits its inactive warmth to the reuse brackish water stream. From the primary stage the glimmering brackish water stream is passed to the second stage which is kept at a somewhat lower pressure more fume flashes off. Simil arly the blazing salt water stream goes to the following stage, etc through the plant with a segment of the fume blazing off at each stage. A warmth balance shows that the warmth provided in the saline solution radiator must be dismissed. This is done in the last two phases of the plant which are cooled by an ocean water stream which hence goes to squander. Current Developments. Huge Multi-impact Alfa laval evaporator In 1990 Alfa-Laval Desalt presented its D-TU idea a ME desalination framework dependent on tube type distillers, by utilizing the vanishing under vacuum with the rising film standard. This is thath implies the internal surfaces of the cylinder are constantly secured with an at that point film of the feed water . warming medium is flows outwardly of the cylinders in the warmth exchangerss.and The vacuum is made by water ejectors associated with every impact. A controlled measure of ocean water is directed to the base of every one of the impact. where it is blends in with the saline solution from the past impact and into the cylinders in the warmth exchanger, where it is warmed. The produced fumes enter a separator where the salt water beads from the wet fume are isolated. The dry fume go through the separator to the accompanying impact where they consolidate. The rest of the ocean water which has been changed over to saline solution, streams to the following impact as feed water. The saline solution is taken out and released over the edge. The inactive warmth in the fumes from the past impact is utilized as a warming medium in the accompanying impacts. The procedure proceeds until the last impact where the produced fumes consolidate cooled via ocean water. The condensate fumes stream starting with one impact then onto the next, and are held in a gathering tank as refined water. On the off chance that a low temperature evaporator is to be utilized for local purposes certain limitations apply. Activity isn't permitted inside 25 miles of the coast or 50 miles of an estuary. Chromate coat water treatment should never be utilized. The condensate must be treated so as to devastate microscopic organisms. Care must be taken if synthetic compounds are utilized to restrain marine development in pipe work. Fume Compression The kettle area is at first loaded up with new water. At the point when the framework is working feed water is provided by means of the level control valve. Hot steam is made in the heater which disregards into the fundamental area. Here the steam is blended in with a brackish water shower. A portion of the steam is consolidated and a portion of the saline solution splash is flashed off. The consolidated steam disregards to the fume segment by means of a scrubber. Stream of fume happens because of the activity of the blower which builds the fume pressure increaseing its immersion temperature. Switch Osmosis Assimilation depicts the procedure whereby a liquid will go from an increasingly thick to a less thick arrangement through a semi-penetrable film. It is critical to the water retention procedures of plants. RO is a procedure which utilizes a semi porous layer which holds both salt and pollutions from ocean water while permitting water atoms to pass. Filtration of up to 90% is conceivable along these lines making the created water unsatisfactory for kettle feed moving forward without any more molding. Improved quality is conceivable utilizing a two or more pass framework. outline indicating osmotic headThe material paper goes about as the semi-porous layer and permits the water atoms to pass yet not the bigger salt particles. Turn around assimilation is the procedure whereby a weight more noteworthy than the osmotic head pressure is applied to an answer of high thickness. Liquid is constrained from the high thickness side to the less thick side. For desalination plants the weight is applied to the ocean water and the water is constrained through the semi-porous layer. The semi penetrable film which is commonly made of polyamide layer sheets enclosed by a winding structure around a punctured cylinder taking after a freely wound latrine roll. Structure of the cartridges is in this way with the end goal that the ocean water feed ignores the layer sheets so the washing activity keeps the surfaces away from stores. A dosing synthetic is likewise infused to help the activity. Make up of layer The two layers fixed on the external three edges, encase permeable under-layer through which the pervade spirals to focal gathering tube Schematic of RO plant Pressurized feed water goes lengthways through the cylindrical winding injury layer component. Freshwater penetrate goes through the film layers as coordinated along a winding shower inot a focal punctured cylinder, while salt water is released out the finish of the layer eleme

Questions: 1. Describe the process of coronary artery atheroma formation: a.Factors that trigger endothelial inflammation b.How high and low density lipoproteins contribute to atheroma formation c.The role of macrophages in it. 2. You are asked to document Mr. Marconi's neurovascular observations (left wrist) during the admission assessment. Discuss the following about this assessment: a. List the 5 parts of this assessment. b.Explain how each of these assessments evaluates Mr Marconis left wrist injury. Answers: (1). Atheroma is the cause for several cardiovascular disorders like heart attack, peripheral vascular disease, angina, etc. They are like small lumps with patchy appearance. This is also known as hardening' of the blood vesicles especially the arteries. a) There are several factors that trigger the inflammation in the endothelial regions such as, oxidized lipoproteins (Libby, 2012). This oxidized low-density lipoproteins or the LDL binds the proteoglycan, involving oxidative modifications. b) Dyslipidemia, which includes very low-density lipoproteins and high-density lipoproteins activating the inflammatory purposes of the vascular epithelial cells; hypertension; diabetes; obesity; infections, etc. These modified lipids carry out alterations in the artery wall triggering the antigen-specific immune responses, hence causing inflammations responsible for the expression of chemokines and proinflammatory cytokinins (Libby, 2012). c) The macrophages play important roles in the coronary artery atheroma formation. After the changes in the peripheral monocytes of the blood, the macrophages integrate some modified lipoproteins with the scavenger pathway. As a result, it transforms into foam like cell which is in a lipid-rich condition providing an important features for the coronary artery atheroma formation with a symptom of lesion expansion and inflammation (Moore et al., 2013). (2). a) Marconi is a patient of 76 years and was admitted to the hospital in the emergency. The 5ps of neurovascular conditions of Mr. Marconi's left wrist after the fall in the bathroom includes 1) Pain which determines the severity and amount of the present pain. 2) Pallor which observes the tissue colour of the distal part. The bluish colour of the tissue indicates the venous stasis. 3) Pulselessness which indicates the extreme of distal pulse and capillary access. 4) Paresthesia which accounts for the numbness or any abnormal sensations in the wrist. 5) Paraplegia is the motion assess. b) Due to the injury in the left wrist resulting in loss of sensation the symptoms may include loss of sensation, numbness, dysaesthesia, etc. He swelling may cause fracture or muscular sprain. It may cause hypertension, as a result of which the patient was suffering from chest pain, exhaustion, etc. If the left wrist appears to be tight and shiny, the compartment syndrome is included as a vital injury (Gui et al., 2012).

A stunning young woman entered and shyly took a seat. She stammered and bit her lip as she tried to relate her story. Finally the detective assured her it would be best to begin at the beginning. Miss Wonderly said that she was concerned for her seventeen-year-old sister, who had run off with an older man named Thursby. She had arranged a meeting with Thursby for that evening, and now wanted to hire a detective to follow him from the meeting - straight to her sister, she hoped. Spade gave his partner, Miles Archer, the details of Miss Wonderly's case. She paid them two hundred dollars, and left with the agreement that Archer would tail Thursby that evening. That night Spade was awakened by a phone call: Archer had been murdered. Spaae rushed to the scene. According to the police ' Archer was shot with a British-made Webley revolver. Spade phoned his secretary and asked her to call Iva, his partner's wife, to break the bad news. Then he returned to his apartment. Sam had just "drunk his third glass Of Bicardi and was lighting his fifth cigarette" when the doorbell rang. It was the police; Lieutenants Dundy and Polhaus wanted to question Sam about the death of yet another man. Thursby, it turned out, had been shot outside his hotel shortly after Spade left the Archer murder scene. Considering the circumstances of Archer's death, the police reasoned Spade must have shot Thursby out of revenge. However, Spade refused to give the cops any information about the case. The next morning the detective had a visitor waiting for him at his office. Effie had tried to keep Iva Archer away, but she had come anyway. Sam was unhappy to see Iva, but still he kissed her. Then Iva asked him point-blank if he had shot her husband so he could marry her. Spade laughed and shook his head. After Iva had left, Spade took a taxi to the hotel where Miss Wonderly was staying, only to find that she had mysteriously checked out, leaving no forwarding address. Back at the office, Effie informed her boss that Miss Wonderly had called to ask him to meet her at a new hotel. Arriving at the hotel, "Miss Wonderly" confessed that her real name was Brigid O'Shaughnessy and that her story the day before was just that - "all a story." Spade also admitted that neither he nor Archer had bought her tale, but had indeed "believed the two hundred dollars." Brigid explained that she could not reveal the complete story of why Spade had been hired, but did say that she had earlier met Thursby in Hong Kong and feared that he would betray her. Then she announced that Tliursby had been Archer's killer; he had shot Archer with the Webley he kept in his overcoat. Sam agreed to continue working on the case. When Spade returned to his office, a gangster, Joel Cairo, was waiting to ask about the connection between the two murders. He confessed his interest was more than mere curiosity; it seemed that Cairo was searching for a missing black metallic bird - a falcon - and that, in some way, Thursby had been connected with the falcon's disappearance. Cairo was prepared to pav five thousand dollars for the statuette's return. Spade told him that when lie could get his hands on the bird, Cairo would be contacted. That evening, as Spade left his apartment to meet Brigid, he noticed a young punk following him. Spade quickly lost the tail and went to Brigid's hotel. Brigid became visibly upset on hearing of Cairo and the money he had offered for the "bird"; she believed that Spade intended to double-cross her, and before she would tell him anything more than what lie already knew, she would have to speak with Cairo herself. They decided to meet with the two-bit thug later that night at Sam's apartment. There, Brigid admitted that though she had no idea why the falcon was so important, she did know where it was hidden. But they would have to wait a

The attitude of American public towards GM food Research Paper

The attitude of American public towards GM food - Research Paper Example GMO food production has identified seven main areas which concern the human safety test in the consumption of the foods and include the study of the DNA and the nutritional contents which are introduced in the new food product and the analysis of the chemical composition of the plant parts as well as the allergens. The human safety test also includes the estimate of the toxicological or nutritional problems which may be encountered by the consumer and the risk of transferring microorganisms in the gene transfer process (Weise, 44). The use of genetically modified (GM) ingredients in food production has attracted a lot of controversy. Public attitude towards these products has being highly negative in most of the developing countries especially Japan and some European countries. The consumer negative attitude in these countries has being attributed to the skepticism on the unknown health and environmental effects of the GMO foods (Tait 4). The negative attributes of the GMO foods has being identified as the spre4ad of the pest resistance herbicide, body allergic responses and the herbicide tolerance on the wildlife plants and the consequent toxicity of the wildlife. However, the full benefits of biotechnology will only be realized when the producers consider the GMO foods to be safe to their health and beneficial. Although many public attitudes towards the GMO foods have been done in the recent past, the public attitudes towards biotechnology seem to be sharply different between countries and the time of the study (Knowledge 5). The consumer attitudes towards biotechnology have been surveyed in Europe and USA over the past decades. From the global perspective, GMO foods have been one of the contentious issues in the society due to economical and technical benefits which are offset by the human health and the environmental impact (Nikki 34). The increase in multinational corporations and economic power of the GMO manufacturing companies has impacted the quality o f the GMO foods and threatened the traditional farming in rural societies in most of the rural developed countries. This paper will review the attitudes of the American public towards the GMO foods over the recent years. Studies in US have indicated that consumers have positive attitude towards the GMO foods compared with consumers in Europe and Japan. For instance, a study carried out by Daniel and Mark in 2001 indicated that 70 percent of the respondents were willing to pay a higher price for GMO foods (Heslop 214). In the US, the consumer makes the decision to purchase the GMO foods based on the uncertainties and the probabilities which are assigned to the consumer risk of the consumption of the GMO foods. The consumption of the foods results to certain payoff utilities which the consumers perceive to receive from the consumption (Macilwain 54). The perceived risks from the consumption of the GMO foods are derived from the future costs which the consumer expects to incur from the decision to consume GMO foods and carry probabilities which are different from one consumer to the other. The perceived risk stems from one of the following sources with the first one being the influence of the media in the

Homework - Coursework Example 1964). Understanding of electrical stress and electrical strength help avoid discharges in electrical appliances which cause insulation failure. The discharges result from high working voltage and can be reduced by reducing the working voltages. For optimum design of electrical appliances, knowledge on the tendency to increase voltage stress is necessary. Proper selection of insulation material for reliability and economic purposes is done in relation to corona discharges and dielectric strength. High voltage engineers must know the field intensities in different media that are under electric stress. This helps in economical and efficient choosing of insulators to ensure reliable operation of the equipment and the correct electrode configurations. Thickness of the insulating material. A material’s electric strength increases at a rate less than that of a linear increase in its thickness. This means the electric strength for a thicker sample is lower than for a thin sample. Therefore increasing the thickness will greatly affect the electric strength of the insulating material (Malik et al 1998). Duration of voltage transients and operation frequency. When operating frequency increases, the electric strength is reduced. The electric strength of a solid material increases fast and nearly reaches its intrinsic breakdown strength if voltages are applied for short periods, in the order of 10 nS. Humidity. Humidity can reduce the electrical strength of an insulating material. The failures are accelerated if there is a difference in the humidity of the testing environment and that of the environment of operation. Temperature. dielectric constant property of an insulating material can be greatly affected by temperature changes. This will in turn interfere with the signal integrity and result to unstable performance For insulators, for example, polyimide, their electrical

Of Mice and Men Essay Example for Free

Of Mice and Men Essay Through considering the roles of characters in the John Steinbeck novel Of Mice and Men I believe that the role of Curley’s wife is significant in the novel. Many aspects of her personality make her so important; other characters opinions on her also form a close judgment towards her from the beginning. I will be analysing her language and the way she communicates with the dominant males surrounding her at the ranch. I will look at how Steinbeck portrays her role in the novel and the impact that has on the reader and how they might perceive her character. When introduced it is clear that she is attention seeking and very much a flirt. Steinbeck describes her by saying, â€Å"She had full rouged lips† and that she was â€Å"heavily made up† and wearing â€Å"a cotton house dress with little red mules, on the insteps which were little bouquets of red ostrich feathers†. It becomes clear that she wasn’t just looking for Curley so she told George and Lennie, but attention from the many men who worked on the ranch. The fact that she was made up also implies that she has a lot of time on her hands and is somewhat bored. Steinbeck portrays her in this part of the novel as a flirt when she’s talking to the men, â€Å"She put her hands back and leaned against the door frame so that her body was thrown forward†. Furthermore, she tries her hardest to make conversation with the men, despite the fact they weren’t interested in speaking to her, she asks, â€Å"you’re the new fellas that just come, ain’t ya? George seemed reluctant to speak to her, he later referred to her as a â€Å"tramp† and â€Å"jail bait† what’s more he snapped at her when she was in the bunk house saying, â€Å"well he ain’t now† suggesting he just wants the conversation to end and for her to go. The introduction of Curley’s wife is an important part of her role, as the reader can easily draw a conclusion about her. Later on in the novel, when she is wit h Lennie in the barn, she says â€Å"go on feel right here† as she entices him to touch her soft hair. She should have known the consequence of what would happen, because she had already unveiled the dead puppy that Lennie had petted too hard, as he liked to pet nice, soft things. Obviously this slipped her mind when asking him to feel her hair, as she was focused on all the attention she craved. A key aspect to look at when analysing this particular character is that the writer, John Steinbeck, calls her â€Å"Curley’s wife† throughout the novel. Not giving her an individual and personal name indicates a lack of authority and that she is owned by Curley and doesn’t have her own independence. Curley’s wife herself also proclaims to being trapped and having regrets about the way her life could have been. In the final chapter when talking to Lennie in the barn she says, â€Å"I can’t talk to nobody but Curley. Else he gets made. † She also confides in him saying, â€Å"I get awful lonely† Steinbeck tries to paint the reader a picture of how much she despises the way her life is. She tells Lennie about how she could have been a star; how she was spotted and could have been â€Å"in the movies† it’s as if Curley is to blame for the terrible life she seems to lead. She tells him, â€Å"I coulda made somethin’ of myself†. It also becomes very clear that she is in the barn to talk about herself only, when Lennie tries to change the subject and move on to talking about himself being able to â€Å"tend the rabbits† she quickly interrupts and continues to talk about her own ambitions and problems. When she is unsure that Lennie has his full attention on her, she abruptly demands, â€Å"You listenin’? † she then goes onto say â€Å"I don’t like Curley he ain’t a nice fella†. Unusual as it is for a woman to talk of her husband this way, Steinbeck wants the reader to sympathise with her in a way. She didn’t want a life like this as she tells Lennie, and this may be why she acts in a way that draws attention. Before Curley’s wife is introduced properly in the novel, there is conversation about her between Candy, George and Lennie. Candy says, â€Å"Yeah purdy but well she got the eye†. Already we can draw a small conclusion the she doesn’t have the best reputation and the men on the ranch are wary of her flirtatious nature. George warns Lennie to stay away from her; he says fiercely to Lennie, â€Å"You don’t even take a look at that bitch† George acts a little distrustful of Lennie and suspicious that Curley’s wife could end up getting him into trouble. She seems to be aware that the men on the ranch are cautious of her, she says, â€Å"Ain’t I gotta right to talk to nobody? Whatta they think I am anyways? † when she’s talking to Lennie in the barn. She may be flirting to draw attention to herself, however the fact that she may be a little too flirt doesn’t cross her mind, and she is asking Lennie for assurance here and doesn’t quite know what she does wrong. In conclusion, I agree that Curley’s wife plays a huge part in the novel, affecting other characters around her and the opinion they have on her, whether it be good or bad. I can decide upon the fact she is after attention, but not just for vanity and self worth, she is lonely and unhappy with her life she lives along side Curley, she doesn’t like the way he treats her and so confides and gets close to other men on the ranch. John Steinbeck gives her an automatically inferior role as he names her just â€Å"Curley’s wife† and gives a clear understanding of her personality before she is even introduced in the novel.

charles schulz :: essays research papers

Perseverance and failure cannot coexist. Failure happens when you quit. When all is said and done, perseverance, commonly referred to as "stick-to-itiveness," is the ultimate success insurance. Nothing can take its place. -Charles Schulz Charles Schulz has persevered through most of his life to ensure that Americans can laugh when they receive the news paper every morning. He worked every day through cancer and wars and even the death of his parents. In a career that spanned nearly 50 years, Schulz drew more than 18,250 "Peanuts" comic strips, which expressed a droll philosophy through his trademark characters, including the hapless, angst-ridden Charlie Brown; Snoopy, a romantic, self-deluded beagle; piano-playing Schroeder; security-blanket toting Linus; and self-centered Lucy. No adult was ever pictured, though the garbled voice of a teacher or parent occasionally resonated in the background. In the beginning "Peanuts" debuted in 1950 and went on to be the most widely read comic strip in the world, with an audience of 355 million in 75 countries. It ran in 2,600 newspapers and was published in 21 languages, including Serbo-Croatian, Chinese, and Tlingit. In a tribute to Schulz, President Clinton said, "For 50 years his keen eye, his good and generous heart, and his active brush and pen have given life to the most memorable cast of characters to ever enliven our daily papers." Schulz died the night before his last strip ran in Sunday papers. In his swan song, he included a signed farewell: "I have been grateful over the years for the loyalty of our editors and the wonderful support and love expressed to me by fans of the comic strip." Born to draw Schulz was born on Nov. 26, 1922, in Minneapolis. He knew from an early age that he was destined to draw comics. As a child, he always had pen in hand. Schulz used the pen for illustrating, not homework, as he flunked several courses in high school. At age 15, Ripley's Believe It or Not accepted a drawing of his dog, Spike, "a hunting dog that eats pins, tacks, and razor blades." He served in World War II in France and Germany. After the war, he dabbled in comics, freelancing for several newspapers and magazines. He drew "Li'l Folks," the predecessor to "Peanuts," for the St. Paul (Minn.) Pioneer Press. In 1950 the United Feature Syndicate began running the strip as "Peanuts," a name Schulz despised. It took several years for the strip to catch on, but when it did, the fire rapidly spread.

Collective security during the interwar period Essay

The term ‘collective security’ can be defined as a security agreement in which all states cooperate directly, collectively, and and every state accepts that the security of one is in the concern of all. In other words, when one of the states part of this agreement violates the rights to freedom of other nations, all other member states will have to join forces to restore peace, penalizing the aggressor state. This model is based on participation and compulsoriness. An agressor state is about to meet a united opposition of the entire world community. The concept of collective security is based on the consent of all or the majority of states to act against any state that unlawfully violates peace. The main idea of collective security is the assumption that no state will want to change the power and order of world community, and if so, all other states will act together against the aggressor state in order to reestablish the global equilibrium. An ideal collective security organization assumes a very high degree of congruent interest among its members. 1 Interstate rivalry and power politics and effectively elliminated.2 As a legal form of states’ cooperation, a collective security system differs from any traditional alliance. The alliance is the way in which a state gets benefits in the event of a conflict after an agreement with another state or several states involved to a predetermined level to maintain their common interest. Alliances form because weak states band together against great powers in order to survive in an anarchic international system.3 The alliance pattern involves the decision to change or maintain the balance of power at local, regional or global level. In general, an alliance has on the other side another alliance with opposite purposes. It is, therefore, a structure of bloc against bloc. Arising from the need to find a way to avoid the outbreak of a new world war, collective security represented, in the interwar period, at least for some countries in Europe, almost the only option of foreign  policy that seemed viable to defend the national interests. The term ‘League of Nations’ (Society of Nations) existed since 1908, when Là ©on Bourgeois4 proposed a new system of organizing international relations. The idea was taken up and supported by groups and associations in France, Great Britain and United States of America, where presidents Roosevelt and Taft supported the formula of a security system in which aggressors automatically received economic and military sanctions from the international community. In June 1915, a League for strengthening peace, supported by Taft, was in favour for a Society of Nations based on collective security and strengthening international law. President Woodrow Wilson is the one who, on 27th of May 1916 marked for the first time, in concrete, institutional terms, the project of such an organization. In 1920, the League of Nations formally established, with the entry into force of the Covenant of the League of Nations, ratified by 42 states in 1919. The organization was meant to include all countries and to resist aggression in all parts of the globe.5 While all members participated in the General Assembly, the League Council was established to guide the operation of the organization. 6 The authority of the League was never seriously questioned, until the early 1930s, when a series of events proved its ineffectiveness. The League of Nations was concieved as a tool for maintaining international peace and security and for promoting interstate cooperation. The main mean by which the League was to ensure peacekeeping was a collective security system, at least in Europe, based on the principle ‘all for one’. According to this principle, all states should have been engaged in mutual guarantee of international peace and security. This concept was included in both League of Nations Covenant and peace treaties. The problem of creating a collective security system specifically concerned the small and medium states. With no ability of defending themselves in the face of possible aggression coming from great powers, the system of collective security was the only defending solution. Hence, the small and medium states were the most active in terms of supporting the Society of Nations’ efforts of peacekkeping. Their position towards this problem proved to be crucial both on the prospects of the forum in Geneva , as in peace prospects. The League of Nations represented a start in the process of democratization and evolution of international life, in the direction of establishing a new system in which  all states can find a place and role, a tribune for expressing their positions, under the aegis of general principles of international law. There were obtained achievements in different fields, of interstate cooperation, there were tested some mechanisms of peacekeeping, there were made efforts for promoting economic development in the spirit of interdependence, which was more and more obvious at an international level. Contrary to all these positive elements, the League of Nations was ultimately a failure and couldn’t fulfill its key objectives: prevent another war by creating a security system based on collective guarantees, resolving conflicts by peaceful means and eliminating economic crises by promoting openness in international trade relations, according to the requirements of globalization. The general crisis in 1929 – 1923 which had devastating effects on the economic, political and moral field and the rise of the totalitarian regimes opened the door for the World War II, which ended, at the same time, the attempt of a League of Nations in building a world of peace, security and prosperity. The League of Nations ceased to function with the beginning of World War II, although the formal decision to dissolve the League was adopted after the entry into force of the UN Charter on April 18, 1946. The United Nations, like the League, emerged in the wake of a devastating war.7 Romania in the League of Nations In order to better understand how the system of collective security works, I chose to talk about what meant to Romania the membership in the League of Nations and the benefits it enjoyed through this status. Romania, one of the 32 founding members of the League of Nations, contributed, under the aegis of this organization, at creating a general security system throughout Europe and especially in South Eastern Europe. Romania’s main purpose was keeping the territorial status-quo, which implicitly meant the integration of Greater Romania. Regarding the benefits of being part of the League, an advantage would be the prestige of being a member, as Nicolae Titulescu said: â€Å"Allow me to express my deep gratitude for the great honor you have done to my country and to me, personally, by handing, through your votes, the great dignity of being President of the 11th Assembly of League of  Nations†.8 The benefits arose from correlating the membership with the fact that Romani a had emerged victorious from the Great War, won enough territories to unite Romanians under one state and needed protection because these territories were an inportant target for the neighbours also. Aditionally, the League united the world’s most influential states and declared a forum for discussion in the spirit of arbitration, consensus and justice. Therefore, the member states were seen from the outside as being driven by the same values. Accepting Romania in the League of Nations meant the acknowledgement that it agreed with the principles of the organization. The League of Nation’s main goal was ensuring peace. From my point of view, all nations that were members of the League, believed in democracy and freedom, but the political leadership had not always reflected these ideals. When the political leadership tended to war, the only barriers were those related to methods and not to ideals. The benefit that Romania had being a member of League of Nations was one of prestige, because joining the organization meant a statement of principles that corresponded to those of the civilized world. Therefore, being a member of the League indicated that the state was inte grated in the world’s civilized nations and that’s what Romania wanted. Joining the League of Nations meant for the Romanian people the end of the period in which was threatened by the Great Powers and could not develop because of that. Once it joined the Society of Nations, Romania acceeded all the international organisms related to the League. Among these, the one that brought the most benefits to Romania was International Labour Organization. A very good study of that time’s ideas regarding the International Labour Organization was made by Grigore Trancu-IaÅŸi9, in a conference form, shown in ‘Romania’s foreign policy, 19 public lectures organized by the Romanian Social Institute’. The author identified the principles of this organization as needed to be urgently implemented by its members. The principles could be regarded as ‘left’, but were more like ideas that approached the society to social justice. The League recognized the idea that its supreme ideal was that peace cannot happen where there is no social justice. The International Labour Organization ensured bringing social justice through the prospect of working conditions. Romania, as a member of the Organization, registerd benefits in the social justice and had the right of decision over these measures. This paper aims to analyze what  collective security meant for the society in the inter-war period and, particularly, what meant to Romania and the effects of being in a collective security organization. Romania had multiple benefits generated by its membership in the League of Nations, even though this organization failed on its supreme mission. Romania’s benefits from being a member of the League related to international prestige, good relations with the neighbours, social justice and the most important, international power increase.

Colorado is known for its beauty, breathtaking views, healthy living, active life-style, its mountains, and superior skiing resorts. Colorado has the highest elevation out of any state! Over 1,000 Rocky Mountain peaks reach over 10,000 feet high and 54 tower above 14,000 feet (America, 2017).
