Adventures Of Huck Finn And History Essays - English-language Films

Adventures Of Huck Finn And History The world in which we live in now is much less oppressive than say the world lived in the middle of the 1800's. Up until the Civil War, the South depended on their ?peculiar institution' of slavery, in order to be productive a successful. Most people believed slavery was not wrong, but those who thought otherwise seldom tried to alter it. In general if surrounded by oppressive environment, one does not usually try to make a difference in that world. This is because people are afraid to defend what is right against a whole mass of people who believe otherwise. Huck Finn in The Adventures of Huckleberry Finn, Billy Budd in Billy Budd, and Frederick Douglass in his autobiography all portray individuals who because of their good, innocent qualities go up against the oppression in their society. Living in an oppressive society does not always draw you to do the wrong thing you are still capable of generating change, whether it be for a certain individual or against a whole mass of people. Billy Budd starts off on the ship the "Rights of Man", Melville obviously showing his intent in the naming of the first ship. This shows that on this ship where Billy wanted to be and chose to be he had rights. That he and the other crew had choices of what to do and how to be. Then along comes the British navy and decides that they are going to take Billy aboard their ship "Power of War". This is when Billy is brought into an oppressive society. This is the navy and wartime during which rules must be followed as well as a lifestyle that must be followed. Billy is a poor innocent boy with a childish stutter. This stutter shows Billy's humane side, a flaw, as well as leading you to the thinking that he has the innocence of a child. This stutter is connected to innocence because of its childish qualities. When most children begin speaking they have some sort of stutter, which usually goes away. The stutter parallels innocence because it is showing that you are just learning how to talk and don't really comprehend the correct way to make sounds, as you grow older you learn and the stutter disappears. Like innocence you are born with it, but as you grow older you usually are not portrayed as innocent any longer. Billy is like the premature kid who still has both his stutter and his innocence. Billy is introduced to many people aboard his new ship and is confronted by John Claggart. In this movie Claggart is the one who Billy must actually go up against. Being in an oppressive society and Claggart being the master Billy is forced to listen to Claggart. Although he tries to avoid him he is nevertheless confronted by him. Claggart and Billy are totally opposite in character. Claggart is an evil man who is out to get Billy whereas Billy is a sweet innocent young man who tries to help others. It is these two opposite traits that eventually lead to the death of both of these men. Billy tries to avoid Claggart because he has heard of his evil and does not want to deal with it. It is until he hears of Claggart's accusations that he is involved in a mutiny that he confronts him leading to the deathblow, which Billy delivers to Claggart. Captain Vere now holds a court to determine Billy's consequences. Captain Vere is torn here between doing the right thing morally and doing the right thing legally, and in the end he realizes he has sworn to uphold the law and does just that. Billy did indeed kill a higher officer and according to the laws must be sentenced death. On the other hand, Billy was sticking up for himself. Captain Vere's legal side wins the battle; Billy is condemned and hanged. Billy's hanging meant a lot. It tore the officers among themselves, most saying Billy was justified in his actions therefore should not be punished to the extent of death. This makes a difference in the whole issue of oppression aboard this ship. We now know that the officers, while usually acting inhumane, actually do have a humane side and are capable of being in touch with that side when needed. Billy changes the society by killing Claggart because now no one aboard the ship will have to deal with his evilness again, although Billy and his goodness

Application of RFID Technology

Application of RFID Technology The discovery of Radio Frequency Identification (RFID) technology was initially met with skepticism. Skeptics were not convinced of the practicability if its implementation and argued that its use was limited. However, it is so much part of life today that it is impossible to imagine life without it.Advertising We will write a custom essay sample on Application of RFID Technology specifically for you for only $16.05 $11/page Learn More RFID technology utilizes radio waves to locate objects. It uses a system of unique codes placed on an object, which are transmitted as radio waves to an electronic identifier. An object can be read beyond its physical visibility range. RFID has three basic components namely: the tag placed on the object, the antenna reader and the computer software. The antenna emits a radio signal, which in turn activates the reading of the transporter tag. The transporter tag has a silicon chip with special encoded message, containing object data. The reader decodes this data and passes it to the computer software for interpretation. RFID is intended to enable the transmission of data from a mobile device, the transporter tag (see Fig. 1). The silicon chip in the transporter tag contains object such as the exact place of location, the date of manufacture, the color of the product, the price, or any other relevant information. Currently RFID is being used to track physical assets, identification of persons, tracking animals, in supply chains, in retail stores, as a mode of payment and in security controls (Association for Automatic Identification and Mobility, 2011). The purpose of this paper is to explain he modern uses of RFID technology and how it affects living. RFID has been found to be more advantageous than the Universal Product Code (UPC) system it replaced. Its range of operation is wider than the UPC. RFID readers can communicate with multiple tags, which do not need to be within sight, at the same time. Most importantly, these tags can store more information about the product than UPC (Umar, Einitz, Imunovic, Andeep, and Ranzon, 2009). One of the most prominent uses of RFID technology is in the food industry. It replaced the less effective Universal Product Code. To begin with, it is used in management of food supply chains. Electronic tags are placed on food items that help in identification during transportation and storage. Such reputable companies like Wal-Mart, uses RFID chips to track its products as they enter its supply and distribution chain. The British Telecommunications company has an innovative way of using RFID. It has created an online tracking system of food products called BT foodnet. This system reduces the cost and the time used on recalling substandard food products (Umar et al, 2009).Advertising Looking for essay on other technology? Let's see if we can help you! Get your first paper with 15% OFF Learn More Other than the supply chain managem ent, Umar et al (2009), explain that RFID is also useful in monitoring temperatures of sensitive food products. The attachment of RFID transporter tags allows for the recording of the temperature of food products and as a result, it becomes easier to evaluate their shelf life. The tags have visual display mechanism that indicates the status of the food item. For example if the item is beyond its shelf life the transporter, tag blinks red. Other RFID tags are a bit complicated and can read and store about 13000 temperature readings in a single instance. These tags can transmit the data for a distance of up to 100 meters. Lastly, this technology has also been useful in maintenance of food safety standards. In transportation and storage of perishable goods like meat and fruits, RFID tags are combined with thermometers that read the storage temperatures. This helps in determining whether the company meets safe food handling standards. It is also used to monitor and determine the ripenin g rates of horticultural products in transit (Umar et al, 2009). RFID has found easy application in mobile phone technology. Mobile phones are equipped with an RFID tag that gets is power form the device’s battery. This tag is supported by the mobile phone operating system, the software in use in the mobile phone device and the mobile phone hardware. Using the RFID technology, the mobile phone acts as the link between all mobile phone solution providers. The transporter tags are used to relay information to these solution providers, and can support and facilitate many inter-service transactions. Mobile phone operating systems have been developed in such a way that they are able to support reader tags used in mobile devices. The current mobile industry is linked with its widespread popularity in its games. The invention of Radio Frequency Identification have necessitated the games industries visualizing on how to design new games that will enable interactions of the virtual an d real worlds, where users can interact with objects that are in transits or stationary. The Radio Frequency Identification does not only mean the interaction of objectives, but also entails the use of other short-range communications such as the Bluetooth or WiFi. These require a source of power and thus can only operate using a passive tag or barcode. Formerly cell phones had an on board camera to decode the code on the camera or from an online database.Advertising We will write a custom essay sample on Application of RFID Technology specifically for you for only $16.05 $11/page Learn More Thus, the existence of Radio Frequency Identification offers an alternative faster solution in mobile games and cameras as their tags can be accessed at a rate of up to 424 kbits/s, while the former barcodes used image capture and processing that is slow as it takes some seconds. Apart from its use in the game industry, the Radio Frequency Identification has found its a pplication as a credit card through a technology referred as Near- Field –communication. This mode of mobile phone payment is currently in its trial in US, Finland, Germany among others. The difference is that with NFC communication is two ways rather than one as in the case with Radio Frequency Identification credit card chips. This makes this new technology more advanced and secure. This occurs when an induced current flows in wire of the coil of NCF when one passes close or in a magnetic field that. Thus, when a mobile phone that is equipped with a NCF passes nearby a NCF- payment station that is producing electromagnetic field and that contain a coil of conductor inside makes an electric current that jumps in between the two coils to be generated. Through this process the user can use his/her mobile phone to transact as if he was using his/her credit card. Nokia 6131 is an example of NFC integrated phone. With such a phone apart from making mobile payments an user can loc k or unlock the door of your office (Layton, 2011). RFID has also proved invaluable technology to apply in hospitals. It is very efficient in management and administration of hospital operations. Gradually it has found acceptance as a solution that will reduce wastages in hospitals. Hospitals use RFID to monitor patient’s actual location, location of special medical equipment and management of patient information among many other functions. In management of patient’s information doctors can scan patient’s mobile tags and access their medical history. Hospital staff can also use the technology on patients before they arrive in hospital by encoding the patients name, condition and location. This makes it easer for hospital personnel to anticipate the arrival of such patients and to locate their movement within the hospital.Advertising Looking for essay on other technology? Let's see if we can help you! Get your first paper with 15% OFF Learn More RFID has replaced bar code technology, which was prone will errors that were too costly to hospitals. RFID has been found to be more useful than just improving the efficiency of manual tasks. It has not only been effectively used in tracking of special care patients that would pose a threat to the public, but also identify and isolate patients with specific ailments in big crowded hospitals. This was found effective in Asia in management of Severe Acute Respiratory Syndrome (SARs) outbreak. The Taiwanese government collaborated with Taipei Medical University Hospital (TMUH) in developing a system of patient tags, field readers and generators that identified the location of SARs victims. Patient’s tags had thermometers that would read patients temperatures. It became easier to identify, isolate and give urgent attention to these patients. Because of the potential of the RFID radio waves to interferer with the functioning of sophisticated medical equipment, the Washington Hospi tal Centre developed the ultra-wideband (UWB) frequency, which operates on lower strength signal, and therefore not powerful enough to interfere with these equipments (Chao, 2007). The use of RFID technology has not been without challenges. To begin with, it is such an expensive undertaking for any company that intends to implement this strategy. Most companies do not see the business sense of installing the whole system that supports the use of RFID, arguing that it has no return on investment. A considerable proportion of these gadgets are not reliable enough. The system also generates very huge amounts of data that most companies cannot manage, even with the help of RFID. Companies need qualified personnel to implement and run, which adds to cost of dong business. There are also privacy issues on the use of this technology, which may violate individual freedoms and liberties. Lastly, the system is prone to abuse. Fake tags can be used instead of genuine ones, thus evading detecti on of counterfeit goods (Attaran, 2009). Fig. 1: RFID technology. Source: Association for Automatic Identification and Mobility In conclusion, RFID technology is very useful in efficiency improvement in modern business practice. Not only does It provided real time information of objects but also creatively used management of complex situations such as identification and isolation of object that pose a threat. RFID has been embraced with considerable enthusiasm as it has more use than the traditional UPC. However, there are notable hindrances for its use, such as hacking, privacy issues, and cost implications, among others. Despite this, it is still being creatively used and its benefits far outweigh the demerits. References List Association for automatic identification and mobility. RFID / what is RFID?. Web.

Life Learning Essay Example | Topics and Well Written Essays - 2250 words

Life Learning - Essay Example Even so, there are some lessons and experiences that one must undergo before becoming a leader. Based on the Kolb-Fry model, one has to undergo an effective learning process that sees one go through the stages of a concrete experience, observation and reflection of the experience, analysis and conclusion, which eventually results in new experiences. Through such experiences, undergoes enough tests to gain leadership traits. While leadership may be inbuilt, at times it involves intensive training before one acquires desired leadership qualities. Through training, one understands the need to inspire and empower others. This lies under psychological leadership in which a person reads the psychology of followers and understands exactly how to direct them to realize organizational objectives. The number of natural born leaders is very few in the current society. I have experienced several leadership mishaps in the organizations I have worked in over the years. To enhance effectiveness in leadership, it is essential for one to train them in lieu to the setting they find themselves at that time. Great leadership is about one’s actions, and not about what they know about leadership. Naturally, I am an outgoing, generous, and carefree person. I am smart can learn anything fast, and have a great memory. I have always had a lot of friends at home, school and work. I have always been a leader and I understa nd how to take on a task and complete with quality. People look up to me at my workplace, and I have been the motivator in the departments I have worked at. Leadership training is at times ineffective. Naturally, leaders are not trained; they are developed. I learnt that it is nearly impossible for a person to tell another on how to lead. Developing a leader is easier and much more effective than training a leader. That is the reason as to why most leadership training programs are ineffective. Sometimes one is just not born

Computational Biology The Serine Protease Active Site Essay - 1

Computational Biology The Serine Protease Active Site - Essay Example Chymotrypsin belongs to the trypsin family of serine proteases and is usually secreted in inactive form (zymogen) in the small intestine. The structure of chymotrypsin was elucidated via the X-ray crystallography.Below is the structure of chymotrypsinogen (see Error: Reference source not found) The active site is the catalytic unit of an enzyme. The determination of the three-dimensional structure of chymotrypsin by X-ray crystallography was the basis of greater insight into the mechanism of action of serine proteases. The Swiss-PDB Viewer software available at http://spdbv.vital-it.ch/disclaim.html was used to manipulate the coordinates of chymotrypsin and subtilisin serine proteases retrieved from the protein data bank (PDB available at www.rcsb.org). The catalytic site of most srine peptidaeses including chymotrypsin is composed of a catalytic traid of serine, histidine and aspartic acid residues. The ezyme the experimnt dealt with are are serine proteases and they have been known to exhibit similar spatial arrangements. However, the residues of the enzymes may adopt different order in the amino acid sequence. Catalytic triad is composed of Ser195 on one side and Asp102 and His57 on the other side inside the active site cleft. An extensive hydrogen bonding network exists in the triad for instance NÃŽ ´1-H of His57 and OÃŽ ´1 of Asp102 and also between OH of Ser195 and the NÃŽ µ2-H of His57. However in the event that His57 is protonated the latter bond is lost (Hedstrom, 2002). Figure 8: The positions of the backbone nitrogens are shown; the residues are Ser195 and Gly193 and the distances from these nitrogens to the peptide carbonyl oxygen. This brings the two residues closer for interactions to occur The catalytic triad in subtilisin contains residues 32, 64 and 221; the oxyanion hole comprises the side chain of Asn155 and the backbone NH of Ser 221; the mouth of the specificity

A Review Of Controlled Release Fertilizers Biology Essay

A Review Of Controlled Release Fertilizers Biology Essay In general, plants must be supplied with nutrients during the whole vegetation period. In horticulture this is achieved by applying quickly soluble fertilizer once to twice a week, for example. This kind of fertilizer application is very labour-intensive and requires considerable specialist knowledge, so as to select the correct rate of application, appropriate time of application and correct composition for the particular plants to ensure optimum plant production. With the use of slow or controlled release fertilizers the full amount of nutrients necessary for the whole vegetation period can be applied at the time of planting or at the earliest stages of plant growth, in the form of a nutrient pool Also, about half of the applied fertilizers, depending on the method of application and soil condition, is lost to the environment, which results in the contamination of water [1].This kind of environmental concerns of feeding crops with traditional fertilizers has led to developing Slow Release Fertilizers (SRFs) or Controlled Release Fertilizers (CRFs). SRFs or CRFs are easy and safe to use. They reduce risk of incorrect fertilizer application; they are labour saving; and minimize nutrient losses by leaching or fixation. The idea of producing SRFs was developed from 1963 by encapsulation of fertilizers by waxes. After that, these products have been commercialized. There are lots of SRF and CRF brands; market leader in controlled release fertilizers is Scotts Professional with key brands such as Osmocote Exact, Sierrablen and Osmoform. SunGro Company is also producing controlled release fertilizers with brand name of Multicoate. AGLUKON is also another commercialized SRF product [2-4]. Like lots of scientific fields, agriculture industry has been over shadowed by nanotechnology. Applications of nanotechnology in agriculture includes agriculture crop improvement, nanobiotechnology analysis of gene expression and regulation soil management, plant disease diagnostics, efficient pesticides and fertilizers, water management, bioprocessing, post harvest technology, monitoring the identity and quality of agricultural produce and precision agriculture[5]. Efficient pesticides and fertilizers in terms of Nano-composite based slow release fertilizers are developing in current decades. Using nanoparticles as reinforcing or cementing agent of polymer coatings has been the only feature of nano particles which is used in preparing slow release fertilizers [6,7]. Fertilizers Fertilizers are applied to soil to promote plant growth. They contain some beneficial nutrients including macronutrients and micronutrients. Macronutrients are nitrogen, phosphorus, and potassium which are added to soil in quantities from0.2% to 4.0% (on a dry matter weight basis) and are more essential than micronutrients. Micronutrients are elements which are applied to soil in much smaller amounts, ranging from 5 to 200 ppm, or less than 0.02% dry weigh. These elements could be sulfur (S), boron (B), copper (Cu), iron (Fe), manganese (Mn), molybdenum (Mo), zinc (Zn)[8,9]. 2.2. Types of fertilizers Fertilizers would be categorized from source of being and also from release properties points of view. All fertilizers could be organic or synthetic from source of being point of view. Organic fertilizers are naturally occurred including seaweed, worm casting, manure, slurry, peat, humic acid, guano and brassin. They provide slow release of nutrient as they need soils bacteria to be broken down to needed elements. Also, they may improve the biodiversity of soil by supplying organic matters and micronutrients for organisms. Organic fertilizers are cheaper and safer than synthetic fertilizers [9,10]. The main synthetic or mineral fertilizers are urea, ammonium sulphate, ammonium phosphate, phosphate rock, potassium chloride, super phosphates, calcium ammonium nitrate, potassium sulphate and NPK, PK and PK compound fertilizers. The most important drawbacks of synthetic fertilizer is their long term sustainability. Also, they are more expensive in contrast to organic fertilizers [10]. Also, fertilizers can be categorized into ordinary and controlled release fertilizers from release properties points of view. Drawbacks of non- controlled release fertilizers Ordinary fertilizers leach to soil very quickly and most of them are not used by the plants. According to figures about 40-70% of nitrogen, 80-90% of phosphorous, and 50-70% of the applied normal fertilizer is lost to environment and cannot be used by plants[11]. This rapid leaching will cause burning of plants and growing in spurts. Also, the lost elements will make some serious problems for our environment. Eutrophication, Blue baby syndrome, soil acidification, persistent organic pollutants, heavy metal accumulation, atmospheric effects are environmental concerns of ordinary fertilizers. Another result of quick leaching of fertilizer is repeating the application of fertilizers which will increase the costs[8,12,13]. Slow or controlled release fertilizers Slow release fertilizers or controlled release fertilizers are coated in a substance that enables a slow release time and eliminates need for constant fertilization and higher efficiency rate than soluble fertilizers [14]. The interest in these materials is for one or more of the following reasons: Availability of nutrients during the hole growing-season; reduced nutrient loss via leaching and run-off; reduced cost and labor outlay in crop production; reduced chemical and biological immobilization reactions in soil which cause plant unavailable forms; reduction of rapid nitrification and nitrogen loss through ammonia volatilization and denitrification; reduced seed or damage from high local concentrations of salts; reduced leaf burn from heavy rates of surface-applied fertilizers; better seasonal distribution of growth and better acclimatization in home or display environment; improved storage and handling of fertilizer materials[15]. Differences between slow and controlled release fertilizers Although there is no a special difference in general function of CRF and SRF, but it should be mentioned that they are manufactured by different materials and techniques with different properties. In slow release fertilizers elements are present in the fertilizers in a chemical form, which is not available to plants and they will be converted by physiochemical effects or microorganisms activities into nutrient forms in the soil. But in controlled release fertilizers elements are packed in coated granules and are released through the coating over a certain period of time. Also, in SRFs nutrients available period is affected by a lot of factors such as water content of soil, Ph, temperature, microorganisms activity, aeration. However, the longevity of CRF depends on coating thickness and temperature of soil. Only coating method is effective in changing pattern of nutrients release and a fixed coating thickness control nutrients release. In CRFs declared release time refers to soil temp erature of 20-21 oC. Higher temperatures accelerate the element release and lower temperatures make it longer [4,16]. SRFs are chemically prepared slow released. Some kinds of SRFs are Urea Aldehydes (UA) and Chelated Micronutrients(CM). Common type of UAs is urea formaldehyde which is high nitrogen fertilizer. Starting release rate of UAs is high but it dies off slowly for 3 years. This kind of fertilizer depends on microorganisms to break it down for plant use. CMs are substances that hold firmly together iron, manganese, zinc, and copper. They slowly releases over a long period of time [17]. 2.4.2. Types of CRFs 2.4.2.1. Sulfur Coated (SC) Elemental sulfur when is oxidized to its sulfate form would be one of the nutrients which is essential for some plants and is normally blended with other fertilizers. Using sulfur coating is also another way to provide sulfur simultaneously with making slow release properties for a core granular fertilizer. As the sulfur containing materials like polysulfides or lingosulfonate are brittle and also give a low wetting of defects they are normally mixed with waxes or plasticizers. Many formulas are available for SCs. Their release time is generally 3-4 months. SDs are released by microorganisms [18-22] 2.4.2.2. Wax coated (WC) One of the methods of reducing fertilizer release rate is dispersing granular fertilizers with molten wax and then cooling the mixture below the melting point of the wax [23]. Paraffin is one of the most used wax as a coating for fertilizers. Paraffin  wax   is a white, tasteless, odorless, waxy solid, with a typical melting point between about 47  °C and 64  °[24]. Other types of waxes are synthetic oil based, petroleum or mineral waxes. Waxes are normally used by an additive or a tackifiere agent to make a good sealing properties [25,26] 2.4.2.3. Polymer Coated (PC) Polymer-coated fertilizers (PCF) represent the most technically advanced controlled released fertilizers. They include a water-soluble fertilizer core and one or more than one layers of polymer. There are large varieties of polymers to coat the core fertilizer also the coatings layer could be the same one or different. In PC fertilizers release of nutrients will happen by diffusion through a semi permeable polymer membrane. Water penetrates the coating and dissolves the core. Release rate can be controlled by varying the composition and thickness of the coating. In addition, pressure builds up can cause cracks to form, from which fertilizer passes into the soil [27, 28]. 2.5. Review of preparation methods of different polymer coated CRFs 2.5.1. Sole Polymer coated One type of polymer coated CRFs is the one which the fertilizer core which could be N, P, K OR NPK compound, is just coated with one or more than one layer of polymer coating. In this case the polymer could be solvent based or water-based. The application process starts with dissolving the polymer in a organic solvent or water. After dissolving the coating will be sprayed onto the fertilizer in a coating drum or fluid bed [29]. Benefits of polymer coated CRFs are as follow; uniform and defect free coating will surround fertilizer; the coating will be very tough and durable which is resistant against mechanical breakdown; they are biologically inactive so they will not breakdown by soil microbes. In most cases except for degradable polymers release of fertilizers will be happen by diffusion through polymer coat rather than through defects. In some other coated fertilizers like sulfur coatings there should be a flaw in coating to make release of fertilizer. There are lots of examples for polymers which have been used in literatures as coating for fertilizers, some of them are as follow; dicyclopentadien[30],Urea and urethane based [31-36], epoxy based [ 37-39], polyvinylidene chloride-based latex[29] carboxyl-carrying ethylene polymers[40], biodegradable starch based[41], urea formaldehyde[42]. However, polymer coated fertilizers have some week points. About solvent-based coatings using large amount of organic solvents like toluene or xylene will lead to environmental concerns. These solvents are volatile and releasing them to environment makes some hazards for human health. Also, polymer coatings are more expensive than sulfur coatings; the process and equipments are also more complex than equipments used for other coatings. 2.5.2. Sulfur-polymer coated One of most common coated fertilizers are the ones in which core fertilizer is covered by a layer of sulfur coating and a layer of polymer. The polymer layer can be primer or outer layer; means that sulfur layer in some researches has been the first layer and in some others the outer layer. Sulfur Using coating is a suggested method to remove drawbacks of sulfur coated CRFs. One of these drawbacks is very fast release of fertilizer in first few days after application. The other one is brittleness of sulfur coatings which may lead to some fractures during handling or storage and losing the fertilizer into soil. Another problem is that sulfur coatings have a high surface tension with water and cannot provide enough wetting for a good diffusion [19, 29, 38, 21]. The most common method for applying the sulfur coating is spray. Molten sulfur compound will be sprayed over a pre-polymer coated fertilizer granule [38,43]. 2.5.3. Wax-polymer coated There are lots of researches focusing on making controlled release fertilizers using Wax-polymer coatings. Wax layer has three major benefits; one is that they are applied over the polymer layer for decreasing the fracture probability of coating and the other one is for decreasing the amount of polymer and avoiding consuming more polymers to make the process cost effective. Also, they can eliminate imperfection of granules surface to make a good surface coating. Most common waxes which have been used in state of the art is C30 alpha-olefin and paraffin. Other petroleum products like lubricants and bitumen or natural products like canola oil, soybean oil, coconut oil and palm oil, also have been used. After melting the wax it will be applied by mixing with polymer coated fertilizer. Normally the polymer is thermoset to avoid any damages of polymer by the wax in its melting point. The wax normally should have drop melting point from 50 to 120 °C. Wax is normally about 0.2% to 10 % by weight of fertilizer [25, 38, 44, 45]. 2.5.4. Filler- polymer coated As mentioned before, despite lots of advantages of polymer coating to make slow release properties when such polymers are used as a sole coating material the ultimate product would be expensive as you have to consume large amount of polymer. Using mineral or organic fillers is one way to avoid using large amount of polymer. Also, in some researches fillers play the role of detackifier, to prevent adherence of coated granules to each other, and strengthening agent [46]. Fillers may be used either as a mixture with polymer to make a nano-composite polymer [47] or as a separate layer. The most common method is second one in which the filler will be added and mixed with polymer coated granules before drying the granules. Most common used fillers are some very fine(less than 20 microns) inert inorganic materials like clay, diatomaceous earth, bentonite, kaolin, gypsum powdered limestone, talc, barium sulfate. Some other fillers like waste cellulosic materials also have used as filler in combination with polymer.[47-51] 2.6. Techniques coating application According to studies have been done; encapsulation methods of fertilizers can be divided into three methods including in-situ, spray and mixing. 2.6.1. In situ This method includes formation of fluid dispersion of the soluble fertilizer in a solvent and mixing the prepared solution with monomers of a polymer. Polymerization will happen and depend on the method; granules or particles of fertilizers will form. Ni et al [52] have developed a double-coated urea fertilizer. For preparation of poly (N-vinyl-pyrrolidone) hydrogels containing urea (PCU), the monomer and a solution of urea in N-vinyl-pyrrolidone were mixed together. The polymerization was carried out at 65à ¢- ¦C for 3 h. The resulting samples were vacuum-dried, milled, screened and stored. After that first coating was dried sample and some amounts of urea were mixed with sodium alginate (SA) solution. Mixed solution was then added drop wise into 5% (w/w) CaCl2 aqueous solution and stirred constantly. The drops immediately turned into granules (about 4mm in diameter) because the SA in the drop was crosslinked by Ca2+ at once. The granules were filtered and dried in oven at 70à ¢- ¦ C. Then the granules were added to ethylcellulose ethanol solution. Multiple EC coatings were prepared by immersion of the previously coated granules into the Ethylcellulose (EC) solution repeatedly. Thus, EC-coated urea granules with different coating thickness were obtained. Hanafi et al [53], have coated a compound fertilizer by polyvinyl chloride (PVC), polyacrylamide (PA), natural rubber (NR), and polylactic acid (PLA) using in situ method. For encapsulation of compound fertilizer with polyacrylamide the granules were added to the solution mixture of monomers. Then the polymerization reaction will start in existence of fertilizers. The thickness of the coating layer on the compound fertilizer granules, determined by SEM, gave PVC compound coated fertilizer the highest value of 3.04 lm, and the lowest was obtained by PA (2.04  µm). Variation in the characteristics of the polymers would be utilized in producing CR compound fertilizer that fit the requirements of growing plants. Hudson et al [38] used epoxy to coat the fertilizer. In this research the urea granules were charged to a pan and warmed to 95 °C. Then the hydrogenated tallaw amine, 2-amino ethyl peperazine and bisphenol A diglycidyl ether were mixed and were added to the granules; meanwhile polymerization happened and prepared mixture was agitated till the fertilizer granules dried. 2.6.2. Spray method This method is most common method for coating the fertilizer granules in state of the art[. Usually, the solution of polymer in a suitable solvent is sprayed on the granule of fertilizer and then the granules are dried to remove the solvent through evaporation. The treatment is repeated as often as necessary until the desired coating percentage is reached. Lan et al [54] have used Chitosan and poly(acrylic acid-co-acrylamide) as biodegradable polymers to coat the NPK fertilizer. The NPK was compound fertilizer granules with about 2 mm in diameter. It was placed in a rotary drum and then the Chitson powder which was dissolved in epoxy-aceton solution was sprayed over the fertilizer. After drying the coating , Chitson coated granules were added to a flask equipped with a mechanical mixer. Carbon tetracholoride, polyethylene glycoloctyl phenyl ether, sorbite anhydride monostearic acid ester, solution of acrylic acid acrylamide , N,N- methylenebisacrylamide and ammonium persulfate was slowly added to the flask. After mixing the coated granules were dried in oven. This product with good controlled-release and water-retention capacity, being degradable in soil and environment-friendly, could be especially useful in agricultural and horticultural applications. Tomaszewska et al [55] have used spray technique for encapsulation of fertilizers. In order to improve the properties of coatings, the granules of previously coated fertilizer (wet method) were sprayed with a polymer solution or pure solvent (N,N dimethylformamide). Concentration of the polymer in solutions used for spraying was in the range of 13-17 wt%. Measurements of thickness, porosity of prepared coatings and microphotographic observation of the coatings were taken. Ma et al [56] have developed a method for encapsulation of fertilizer with a self assembled coating. The fertilizer granules were heated in a rotary drum to 75 °C for 10 minutes. Then the self assembling amphiphilic molecules (N,N-bisaminoethyl eleostearate) were sprayed over the fertilizer. After 20 minutes aliphatic isocyanates were sprayed over fertilizer. This process was repeated once again. The fertilizer kept for drying in the 75 °C for 20 minutes. Dai et al [57], have developed a controlled release fertilizer using a water soluble resin as a coating. The granular compound fertilizer was coated in fluidized bed. Lan et al [58], prepared a double-coated slow-release NPK compound fertilizer with superabsorbent and water-retention properties (DSFSW), whose inner coating was chitosan (CTS), and the outer coating was crosslinked poly(acrylic acid)/diatomite-containing urea (PAADU). This prepared product not only has slow-release property but also could absorb a large amount of water and preserve the soil moisture at the same time. In addition, the outer coating (PAADU) could protect the inner coating (CTS) from mechanical damage. These were significant advantages over the normal slow release or controlled-release fertilizers, which generally have only a slow-release property. The results indicated that the DSFSW could be found an application in agriculture and horticulture, especially in drought-prone regions where the availability of water is insufficient. At first the outer coating containing urea diatomite (PAADU) was prepared. The NPK compound fertilizer granule was placed into a rotary drum, and the Chitosan powder was stuck on the granules by means of epoxy dissolved in acetone. The adhesive was applied by spraying at regular time intervals. The process was finished until compact and homogeneous coating formed on fertilizer granule. The coated granules were dried to a constant mass at room temperature for 6 h. Then the CTS-coated NPK compound fertilizer granules were obtained. CTS-coated NPK compound fertilizer granules were dipped in water and then were immediately placed on PAADU powder and shaken. In this manner, PAADU could adhere to the surface of CTS-coated NPK compound fertilizer and form the outer coating. The surface of the product was crosslinked by spraying methanol solution of epoxy chloropropane and then dried in a 70  °C oven to obtain the final product, i.e., the double-coated slow-release NPK compound fertilizer with superabsorbent and water-retention. Hansen et al [36], encapsulate the granular fertilizer with the epoxy resin using spray method. In this research not coated fertilizer was placed in a rotating drum and pre heated to 250 ° F. A rapid drying solution of copolymers dicyclopentadiene and a modified vegetable oil were applied over fertilizer using spray in a thin stream of resin. Simultaneously hot air was passed through drum. Next monomers of second resin including a mixture of epoxidized soybean oil and polyester curing agent were applied over prepared granules. The solvent was a mixture of xylol and Cellosolve acetate. Hansen et al [39] also have used the above mentioned method for encapsulation of fertilizer with polyurethane. First of all the preheated fertilizer was coated by a synthetic drying oil. After drying the coating for a few minutes fertilizer were dusted by clay. Then Urethane solution in xylene and Cellosolve acetate were applied using spray. 2.6.3.Simple mixing In this method granules are simply mixed with the coating at its melting point or with a solution of polymer in a suitable solvent. Tomaszewska et al [59] used this method for coating the granular NPK fertilizer with polysulfone (PSF), cellulose acetate (CA) and polyacrylonitrile (PAN). The coating solutions were prepared by the dissolution of the solid polymer in adequate solvent. The NPK fertilizer was successively added to adequate polymer solution, and was covered by a thin layer of the solution. Subsequently, granules were dropped into water, where the gelation process takes place. The coated granules were removed from the precipitation bath and then dried to a constant mass. The multiple coatings were prepared by immersion of the single coated fertilizer into adequate polymer solution, then into water and drying. Hon [47] has prepared the coated granules by mixing method. After melting the thermoplastic polymer by heating, the cellulosic additive has been added to melt resin. Then after allowing the temperature to drop, for avoiding the fertilizer damage, the granules or powder fertilizer has been mixed with the prepared mixture using a Brabender Mixer. Markusch et al[60] just has mixed the fertilizer pellets with at first, a diluted polyol and then with a diluted isocyantae to make a polyurethane coating. Then the feretilizer were placed in oven for drying. 2.7. Special equipment for application of polymer coating Typical physical method for encapsulating fertilizers are spray coating, spray drying, pan coating, rotary disk atomization. Special equipments for these methods are rotary drum, pan or ribbon or paddle mixer, fluidized. Fluidized bed and rotary drums are the most important equipments [87, 88] Polymers used as coating for CRFs A broad range of polymers has been used in fertilizer coating. These polymers could be thermoset, thermoplastic or biodegradable. Some of common thermoset polymers are urethane resin, epoxy resin, alkyd resin, unsaturated polyester resin, phenol resin, urea resin, melamine resin, phenol resin, silicon resin. Among them, urethane resin urethane is very common used.[36,61] Thermoplastic resins are not very common used in art because of some problems. As mentioned before a very preferable method of applying polymers is spraying the dissolved polymer over granules. Either some of thermoplastic resins are not soluble in a solvent or make a very viscose solution which is not suitable for spraying. Polyolefine is used in art for coating the fertilizer granules [47,62]. Biopolymers, dispose in bioactive environments, degrade by the enzymatic action of microorganisms such as bacteria, fungi, and algae and their polymer chains may also be broken down by non enzymatic processes such as chemical hydrolysis. Non-biodegradable polymers are not environmental friendly. Due to environmental concerns there are some trends of replacing non-bio with bio degradable polymers as coating material from 1970s. But it should be mentioned that they are expensive yet and not very cost effective. Also, in production process durability of polymer should be adjusted with release time of fertilizer. Among natural and synthetic biopolymers starch and cellulose based polymers, chitosan (a linear  polysaccharide),poly lactic acid and poly(ÃŽÂ µ-caprolactone) due to low cost and abundance are some of used biopolymers in fertilizer industry[41,52,58,63-69] 2.5. Coating thickness Generally, polymer coatings are applied in a thickness which is suitable to make a desired controlled release property. Thickness could be related to characteristic of polymer and also it depends on existed porosity of polymer surface. If water vapor transmission rate of coating material is 0.01 to 20, coating thickness would be 1 to 100 microns. Preferred coating thickness is 1 to 50 microns. Coating process could be repeated more than one layer to get desired nutrient release [49]. 2.6. Investigation of release behavior of CRFs Release mechanism for different coatings is different. Thick encapsulated granules like sulfur coating will allow the nutrient to release when a flaw or rupture appears on the coating surface. In this case, rupture will happen because of permeation of water into coating and inside osmotic pressure. Also, biodegradable polymers will release nutrients while destroying by soil microbes activity. Polymer coatings or combination of different coatings will happen by diffusion of water through walls porosities. In this case release rate of can be controlled by the particle size of coated granules, thickness of coating and permeability of coating surface. Also, altering the chemical composition of fertilizer core and the coating will change permeability of coating; means that even basic or acidic environment will change the permeability. In some researches when the coating has been starch-vinyl, increasing size of encapsulated granules has led to slowing down the nutrient release [70, 71]. There are some standard test methods for measurement of controlled release properties. According To European standard the standard release time of N during 24 h should be 15% of total core nutrient. Also, release rate for 15 day should be 75% of total nutrients. Also American and Japanese standards say that the initial release shouldnt be more than 40% of total nutrient. According to European standards for measuring the release rate encapsulated fertilizer should be immersed in pure water at 25  °C (room temperature) in incubated state [72, 73]. For example Detrick et all[43] have investigated the release behavior of their product by immersion of 20 g of encapsulated granules for 8 h in water. After filtration of solid they dried the solid. Evaporation of water was done at 100  °C for 8 hours. Also, Ma et all [31] placed 14 g of granules in wire mesh holder into a jar with 300 ml water at 23  °C and agitated ir by an orbital shaker. Then, the adequate water was taken for elemental analysis.. Locquenghien et al [40] for investigation the slow release effect of fertilizer some amounts of fertilizer were continuously extracted with water. For this purpose the granules were arranged in layer in a cylindrical vessel field with water. Water was passed through this layer and its Nitrogen content was analyzed. 2.8. Commercial CRFs in world and Malaysia Urea-formaldehydes are oldest slow release products which were produced in 1936 and then were commercialized in 1970s. These products were known as Ureaform, Bluchip, Nitroform Methex and Nutralene. After that Tennessee Valley introduced sulfur coated urea technology in1960s.Polymer coated fertilizers were produced as early as 1970 in Japan. Most important commercialized polymer coated CRFs are Osmocote, Nutricote [74] Osmocote CRFs are NPK granules coated by a thermoset copolymer of dicyclopentadiene and a glycerol ester (linseed oil) dissolved in an aliphatic hydrocarbon solvent. The Osmocote CRFs are normally used for ornamental horticulture production like greenhouses, nurseries , citrus , and strawberry production[75]. Nutricote prills are encapsulated by thermoplastic resins likeas polyolefins, polyvinylidene chloride. The process of Nuricote involves dissolving polymer in fast-drying chlorinated hydrocarbon solvents and then applying the solution to a variety of nutrient substrates including urea, potassium sulfate, diammonium phosphate, ammonium nitrate and potassium chloride. Blendin the polymer with talc and ethylene-vinyl acetate has been done to obtain desired release rate[76] Sierra, Lesco and polyon are some other commercialaized CRFs in the world. In Malaysia two brands named Greenfeed[77] and KAMILA[78] has developed slow release fertilizer. Greenfeed contains Zeolite which helps to release nutrients when it is in contact with soil. KAMILA is specially formulated for oil plantation industry. 2.9. Tracing nano-technology features in fertilizer industry Reviewing literature shows that researches which have used nano-technology features in fertilizer industry are very rare. The main benefits of nanoparticles in these researches are using them as reservoir of fertilizer or as filler [79,80]. Solid nano-particles, have large surface areas and their reactivity is much more greater than that of micrometer size materials. Also, their surfaces and interfaces provide an active substrate for physical, chemical, and biological reactions [80]. Two published researches have done using nano-particles. One has used nano-clay as carrier of metal-urea complex; urea intercalated clay without any coating has been developed as slow release fertilizer[79]. In other one, a nanocomposite of nano particle, fertilizer and polymer has been granulated and developed as slow release fertilizer. The production method involves mixing monomers, adding nano particle, which could be nano clay, nano bentonite, nano kaolin, polymerization and then granulating the mixture. In this research nano particle just work as good and effective filler [81]. Making polymer-nano-particle composites is something common in industries. Lots of researches have been done in this area, but researches around using nano-particle as reservoir for fertilizer have been done rarely. For more study here, we will review the researches have been done. 2.9.1. Interc

industrial revolution :: essays research papers

The impact that The Industrial Revolution had on Europe and England was big, it practically changed the economy for years. There were many individuals that had a big impact and there are many acts, rights, and processes devised to produced the most making for the higher classes. Most of the individuals that are involved had invented something that would change a certain company. This whole industrial revolution started small. In fact, it started out with tiny little village entrepreneurs. Entrepreneurs were tiny company’s that would make hand made stuff and sell this profit that is produced. This soon led to more money, which led to more employees, which also led to more entrepreneurs, and it spread ideas. This got people really thinking. One man named Robert Owen a young utopian socialist of Britain who became the manager of his own cotton mill at the age of nineteen. He then developed community farming and had the town of New Lanmark, Scotland living and working for him. He provided proper housing, basic education, and an inexpensive company store for the workers. In fact, he made a very good deal with his employees, that benefited them and he still made a good profit from it. He forbid young children to work in his mills, and he decreased hours and increased wages. One of this man’s supporter’s is Charles Fourier He favored ideal comm unities and that all work should be shared and that the higher class would benefit of the joint labor according to the needs of the lower class. This man boosted the economy tremendously, because he spread his idea of community farming and farmers and entrepreneurs were beginning to use it more often and they were making good profit. However, some entrepreneurship leaders got to greedy and wanted more money so they made deals that basically only benefited them and they built self-centered industries. These deals included lowering the age of working ability, which led to less education, which led to lower wages. The working conditions were horrible and if you lost an arm or any sort of limb they were fired and another child was hired in replace of them. Men like Karl Marx and Friedrich Engles joined together in 1848 to produce the Communist Manifesto. This was a pamphlet that was intended for the workers.

Assignment: Negotiation Plan Daily Dairy Company Essay

The Dairy Company is proud to be one of the most successful companies in the country that provide milk-based products to Australian customers as well as oversea. As we look at the future of the company, it is necessary to restructure the company body frame, strengthen employer-employee relation, the main endowment factor of our company. It is important to come to the satisfactory agreement that could benefit both parties. Dairy Company Goals: 1. The agreement upon the appreciation in salary is to be indicated during the life of the agreement. 2. Training module to be provided to employees 3. Develop an efficient hours roster 4. Maximize the duration of the agreement 5. Consultative Committee structure and confidential information Dairy Company Strategies Daily Dairy is very well aware of the important of employees, the undeniable part which largely contribute to company’s benefit. The company feels that it must develop a solid agreement to benefit every single contributor, but it also wishes to remain flexible and open to new changes and to the variation of demanding market. An integrative agreement is much needed. †Most negotiators would prefer to be involved in the more integrative approach to bargaining, which is a good choice as the research generally suggests that the integrative approach yields better results† (Walton and McKersies’s 1965) 1. The agreement upon the appreciation in salary is to be indicated during the life of the agreement. As the recession coming up, the prediction of 10 to 20% of employees will be cut down to reduce expenses and raise a significant amount to capital. A part of the surplus amount e contributed to the capital will be added to the current salary. The purpose of this appreciation is to enhance the life standard of each individual, furthermore  improve the productivity of employees and production line of Daily Dairy in general. The appreciated proportion will be determined by the proved contribution towards improved productivity of each individual performance. The total amount increase benefiting employees is predicted to be 5% rising from 65%-35% between company and workers to 60%-40%. As the disappointing productivity in recently month, employment diminishing is inevitable but to encourage these employees by adding more shared benefit, we believe it could improve the general production line. We believe that the agreeable rates can be determined by reasonable flexibility from both sides and are prepared to offer several concessions of our own. Fell stated in his Clear-cut compromise strategy that â€Å"the split different between what you and other party want, so both get something, and neither of you gets all that you wanted†. (Fells,R.E 2012). 2. Training module to be provided to employees Training opportunities are already given for potential employees. The quantity can go up or down depend on the availability of vacancies. However, we agree to give more training opportunities to employees for contingency problems, and upcoming expansion. As we have stated above, the salary appreciation is counted based on individual performance. Workers will be paid upon the contribution of their work, not for the skills they hold. 3. Develop an efficient hour’s roster We believe that in order to achieve productivity, efficiency rosters are much needed for each individual. A pattern has been build up to achieve efficiency from both company and employees. In this pattern, both parties specify their requirements, limitations and thus come to an agreeable terms. For this instance, Daily Dairy required each employee to fulfill 38 hours per week with an optional of working overtime. Alternatively, employees can state their preferred working time, number of overtime hours. Agree to these terms, Daily Dairy will make sure providing the best possible roster to each individual, and employees are obligate to fulfill what has been agreed upon. In return, we need employee to be flexible to new roster in the time of increased demand; seven day notice will be given to any changes in roster. By optimal the employee rosters in ordinary business day, we satisfied their needs thus we can expected improved in productivity. Furthermore, in the time of need, we also can expect the same productivity from employee regarding the changes in roster. It’s the win-win situation that Daily Dairy wants to achieve. â€Å"the win-win situations exist where some value are created that did not exist, or seem to exist when the parties first started negotiating†.(Fells,R.E 2012). 4. The duration of the agreement The longer the duration of the agreement the better off for our company. At first, Daily Dairy can avoid dissipating both human and money resources on these repeatable problems and focus on more pressing matter. Secondly, with a predictable fixed in labor cost, we can achieve more stability and further benefit toward company, money in general. In short-run, wages could not reflect the price-level change (inflation rate), so worker are actually work under wages. In short, while the labor expenses are fixed, our profit is variant, the different will benefit us in the long run. We want to achieves 4 years agreement. Thus we should make the initial offer and it should be higher than 4 years. â€Å"A first offer tends to become an anchor for the negotiations, so going first has aan advantage ( Galinsky & Mussweiler 2001; Magee, Galinsky & Gruendeld 2007) 5. Committee structure and confidential information Employees are the main skeleton which structures the appearance of company. With this in mind, we want to build a most effective joint workplace committee that enables the possibility to have a mutual understanding between company and workers. With a consultative role, committees can provide management with worker viewpoint before decisions about the workplace are made. Recognizing that the current industry is very competitive and maintaining secrecy about Daily Dairy’s strategic information is the most important, confidentiality information must be kept safe from outside world which includes committee. â€Å"The trust required in these specific situations is separate from whether the other negotiators are inherently trust worthy† (Fells,R.E 2012). The benefit returns is not worth the risk. Conclusion We have showed our reciprocity in some matter and also in some we stand a firm ground but after all, we believe that these concessions show our good faith and will enhance a mutually beneficial relationship between our company and employees. We hope this agreement would result in a significant amount of productivity growth, and would also serve to strengthen our infrastructure and our mutual benefit as a whole. References Fell,R.E.

US Economy & Outsourcing essays

US Economy & Outsourcing essays The United States Economy and Outsourcing Outsourcing is an agreement to have work done for a company by people not employed by that particular company. Outsourcing is a trend in corporations that is especially found today in the information technology field. In certain businesses, the whole information management of a company is outsourced. Outsourcing varies from large contract, large companies doing work for small companies and vice verse, to small contract, hiring substitute workers. Outsourcing does not necessarily take place internationally; it can be a domestic matter, although my topic deals with sending jobs overseas. The reason outsourcing has expanded these past few years is because it helps the economy in the long run. It prevents high labor costs in businesses, which allows companies to make more profit and create more jobs. Yet there is much debate over sending jobs to low-wage nations such as China, Romania and especially India. Many employees in the United States have lost their jobs to workers in these foreign countries. These unemployed Americans are asserting that outsourcing is only assisting the large corporations, but not helping the economy. They are arguing that it gives more money to the management at the top and dismissing workers at the bottom. What the jobless are missing is the big picture in the U.S. market. Companies are able to save a minimum of twenty to thirty percent through outsourcing. The money conserved is put back into jobs, stock dividends and profit sharing. Outsourcing does not automatically succeed in every situation. Some Dell customers have complained about la nguage barriers and delays for certain call centers. Delays are inevitable and likewise found for American help services. Language difficulties, on the other hand, can be a major issue. India, which is the top nation for outsourcing, has an elaborate schooling system that teaches English as one of the primary languages. When corpo...

Using the Adjective Lackadaisical

Using the Adjective Lackadaisical Using the Adjective Lackadaisical Using the Adjective Lackadaisical By Maeve Maddox One of my mothers favorite words was lackadaisical. Example: Dont vote for her to head the committee. Shes too lackadaisical to get anything done. Some people use lackadaisical as a synonym for lazy, but thats not quite what the word means. This headline indicates the difference: FCC: Lazy Or Just Lackadaisical? Lazy implies the deliberate avoidance of work in order to spare oneself effort. Lackadaisical implies lack of purpose. The lazy person has a purpose. The lackadaisical person is content to let things happen. The adjective lackadaisical derives ultimately from the word lack in the Middle English sense of loss, failure, reproach, shame. When people were overcome by the sadness, unfairness, or futility of life, they would put the back of their hands to their foreheads and exclaim Ah, lack! Ah, lack became the word alack. Then came the expression Alack the day! On a day, alack the day! †¨Love, whose month was ever May,†¨ Spied a blossom passing fair,†¨ Playing in the wanton air†¦ Shakespeare, Loves Perjuries Alack the day contracted to the interjection lackaday: Ah, lack-a-day! its a troublesome world! Lack-a-day became lack-a-daisy: The carpenter..said ‘lack-a-daisy!’ when he saw that the old theatre was pulled down. The whimsical adjective lackadaisical derives from the exclamation lackadaisy. The OED gives this definition of lackadaisical: Resembling one who is given to crying ‘Lackaday!’; full of vapid feeling or sentiment; affectedly languishing. Said of persons, their behaviour, manners, and utterances. Merriam-Webster defines lackadaisical this way: lacking life, spirit, or zest : devoid of energy or purpose These examples from the web indicate that lackadaisical is now used most often to mean lack of energy or purpose: Having a lackadaisical selling effort is nothing to be proud of Cleveland police remain too lackadaisical in handling sex crimes Lackadaisical play irks White Sox manager Ozzie Guillen Giuliani: Obama has lackadaisical attitude toward war, Gulf oil crisis Why are todays teenagers so careless and lackadaisical?

Tesco in India Essay Example | Topics and Well Written Essays - 2000 words - 4

Tesco in India - Essay Example This paper illustrates that Tesco is the second largest retail chain after the United States giant Walmart and is the leading retail chain in the United Kingdom. The company is involved in offering both food and non-food products to its customers. Tesco with the proposal to open multi-store in India is the first international retailer interested in penetrating the Indian market after the resolution pass by the Indian government to allow foreign investment in the multi-brand retail in 2012. The government of India has revealed its positive approach towards this initiative of Tesco. If the application is approved by the government of India, Tesco intends to enter the country in 50-50 partnerships with the Indias Tata group. Tata group owes Trent Hypermarket Limited, that majority operates Star Bazaar and Star Daily in the western region of India namely Maharashtra and its neighboring state of Karnataka. Culture is defined as a complex set of knowledge, beliefs, perceptions, morals, att itudes, customs and any other capabilities or habit acquired by an individual as a member of society. Correspondingly, cross-culture represents the differences between the countries in terms of culture acquired by the people of the respective country. Schein regarded culture as the key source of organizational culture. Accordingly, culture affects the business in every stage of organizational operations. It is thus argued that understanding culture is of prior importance for the business particularly those intending to or operating in the foreign market. Moreover, it has been noted that corporate culture can impose serious constraints on strategy and act as an impeding factor in the course of achieving the business objectives. It is thus crucial for Tesco to identify the differences in the UK and Indian culture for deriving considerable understanding regarding the cultural issues that may affect the business process of the proposed joint venture.

Healthy People 2020 Assignment Example | Topics and Well Written Essays - 1250 words

Healthy People 2020 - Assignment Example Unlike many other neighboring residential areas, Sunnyside still boasts of mom and pop businesses. The boundaries of Sunnyside roughly correspond to those of 11104 Zip Code. It is an area of nearly one half square mile. By 2014, Sunnyside had a total population of about 29,000 people (NYC Department of Health and Mental Hygiene, 2015a). Majority of the Sunnyside dwellers are first time mums and small families. This is basically because most of the houses in the area were initially built to accommodate small families. The initial houses were one to two bedroom units. It is however, worth pointing out that in some areas, developers have demolished the old houses and put up residential house that can accommodate large families. The residential buildings and units have gardens that are used for family gatherings, social events and as play areas for the young ones. Sunnyside neighborhood is best known for the Sunnyside Gardens Historic District. This is one of the first planned communities in the entire United States of America. It was built between 1924 and 1929 (Haller, 2015). The Sunnyside Gardens Historic District appears more like an old English town with gabled brick town houses. The area also boasts of verdant court yards as well as several pathways that weave between the buildings and residential house. The houses that were built during the 1924 planning period have been maintained with renovations being done on regular basis to ensure that they are in good condition for use by the Sunnyside dwellers. According to Haller (2015), the bike lanes and the Sunnyside gardens in the area has made it very attractive to small families and parents who are having their first children. The bike lanes are well kept and maintained. The lighting system in the various lanes and pathways has been perfectly done making it appear as a modern residential area yet it way planned
