Economic Order Quantity A lot of companies worries about two things when deciding how to manage their inventory. First, is how much theyshould order? Second, how often should they order. The Economic Order Quantity, EOQ, determines the appropriate amount and frequency to order and hold inventory. Is the amount of inventory to be ordered at one time for purposes of minimizing annual inventory cost. The EOQ formula is: where: Q= the EOQ order quantity. This is the variable we want to optimize. All the other variables are fixed quantities. D= the annual demand of product in quantity per unit time. Also forecasted monthly usage. S= the product order cost. Cost per order event (not per unit) C=Unit cost. H= Holding cost per unit as a fraction of product cost. An example: The demand for Klabitz?s is 50 per week. The order cost is $30 (regardless of the size of the order), and the holding cost is $6 per Klabitz per week. Plugging in these figures into equation 1; the EOQ formula we get: The greater the Q, the order cost would decrease due to less orders placed. On the other hand, if Q increases, the holding cost would increase due to higher inventory levels. The graph is: From the graphic we can see that while the holding cost increases with quantity ordered, the ordering costs decreases. At the same time it can also be seen that purchase order cost is constant as it is not a function of the quantity but of cost alone. The point where the lines cut and where the line starts going down is the EOQ. From the graph Total cost TC = Purchase cost + Carrying cost + Ordering cost Purchase cost = D.C where D = annual demand in units, C = Cost per unit Ordering cost = [D/Q] * S where D = annual demand in units; Q = EOQ and S = order cost or set-up cost So the important thing here is that the total cost, is the minimal cost that you can have when the inventory tends to be cero, with the purpose of finding the minimal cost. EOQ whole model bases in founding the point, where the costs of ordering a product and the cost to maintain the product in the inventory are equal.

Jamie Oliver Essay Essays

Jamie Oliver Essay Essays Jamie Oliver Essay Essay Jamie Oliver Essay Essay Jamie Oliver is a chef who has made a number of television programmes for Channel 4; in most of these programmes he is cooking and instructing the audience, although he is sometimes part of documentaries about food, for example in schools. His style of speech is very different to many of his contemporaries: he uses his distinctive style to present himself as a down to earth, friendly TV chef. Oliver is the only person talking in this transcript because he is cooking and explaining his actions for the TV show. The fact that he is cooking while talking means that there are numerous pauses in the transcript, for example ayou wanna coat the bottom (3) of the pana. The three second pause indicates that he is demonstrating this action on the programme; it is important in his role as a TV chef that he doesnat just sit and talk through a recipe because viewers want to see the recipes being made and they also want to be entertained and kept interested by Oliver moving around in the kitchen. Other pauses suggest that, although this programme is probably scripted to some degree, Oliver is not reading from an autocue but retains an element of spontaneity to his speech. The pauses at the start of the transcript, aI got a pan (. ) er the right size pan about (. ) sort of seven inchesa, are indicators of this spontaneity, as is the non-fluent aera. Although sometimes a sign of nervousness, in this case I think the pauses help Oliver to appear normal, like his viewers, so they are more likely to attempt his recipes and, of course, buy his books. Jamie Oliveras Esturary accent and his accompanying use of London slang are also distinctive features of his talk. Words such as achivvya and asquigglea are colloquial and are not words we expect to hear on a cooking programme. We are used to words from the cooking semantic field such as awhiska, abakea, astira but Oliveras language use again makes him seem very normal, approachable and relaxed. As well as specifically accented words such as the dropping of the aha in aorriblea, Oliveras elisions agonnaa, awannaa and akindaa demonstrate his relaxed tone. As well as using these to build a successful TV persona, Oliver could be using this informal language because he is concentrating more on the actual cooking and explaining the key details of the recipe

Finger print as a crime fighting technology Essay

Finger print as a crime fighting technology - Essay Example (Cowger, p56) Fingerprinting has turned out an important and useful biotechnological application as there are several benefits of DNA fingerprinting. It helps the medical scientists in the identification of the organisms causing different diseases. With the help of DNA fingerprinting the paternity of a person could be established so the babies could be identified even if their parents were switched at birth time. Along with that DNA fingerprinting also helps in criminal investigations (Grew, p566). The investigators can take any skin tissue, blood drop or semen from the crime place and then use to decide weather any particular person was present at that place or not. Moreover DNA fingerprinting also helps in the identification of a body when it is decomposed or now available complete due to any incident (Beavan, p98). The use of fingerprinting is getting popular for different purposes due to variety of advantages offered by this technology however there are some negative aspects of t his application as well. There are some technical difficulties associated with DNA fingerprinting for example there is possibility that any error can occurred in the hybridization and probing process. In this way the investigation of a crime or paternity identification could be misguided however there are little chances for errors in this test. The probability determination and population genetics are the other problems related with DNA fingerprinting (Belkum, p122). An important application of the latest technology of fingerprint is its efficient use for fighting against the crime. It has been evolved as an important crime fighting technique as it helps the investigators in finding out the potential suspect of the crime by telling about the people present at the crime scene. There are several developments in the field of fingerprint that have allowed the investigators and crime fighters to refine their efforts in the field of crime fighting and investigation. For instance, the poli ce now commonly use the automated license place recognition camera for finding the stolen vehicles (Scheibert, et al, p1503). There are certain techniques within the fingerprinting technology that allow reaching the suspects in different ways. For instance, the brain fingerprinting technique is also used for meaning the suspect electrical brainwaves. In this method, the police make the suspect wear a headband embedded with electric sensor and the different images are shown to him on the computer screen. It is based upon the belief that the brain reacts in specific manner towards specific type of information and the brain activity and response towards certain pictures of the crime scene could help finding out his involvement in the crime (Cowger, p56). Due to the increased use of fingerprint for the crime prevention it has become a common practice in most of the countries of the world that the people are required to give their fingerprints at several locations like shopping mall, air ports and other public places. It allows maintaining the record of the fingerprints of the people visited at particular place during that time and later these fingerprints could be used to match with the fingerprints found at any crime scenes. These fingerprints also allow sorting out the people involved in any crime committed earlier. In this way, the fingerprinting technology allows fast recognition of the crime suspects. The most important use of fingerprinting te

Book review,William Shawcross,Deliver Us From Evil Essay

Book review,William Shawcross,Deliver Us From Evil - Essay Example Unlimited powers, aided by astonishing schineitif and technological achievements have rendered the task or peace more difficult. A small mistake by the decision making authority could result in enormous losses to humanity. The war of push-buttons is unimaginably calamitous than the war of weapons that were used by the war-machine during the I and II World Wars. William Showcross shows the great duress under which Kofi Annan functioned. Failure of men like Kofi Annan is the failure of UN, as Showcross puts it succinctly. The purpose of the book, broadly speaking, is to highlight why UN fails in its avowed objectives of establishing peace in the troubled regions. For example, about Iraq, he writes, when United States and Britain did bombings for four days, in 1998, Annan made a short statement, â€Å"This is a sad day for the United Nations, and for the world—it is also a very sad day for me personally.†(Showcross, p. 33) Showcross has highlighted in the book, how the Secretary General, has to work under very difficult circumstances, will be squarely blamed by the suffering people, for allegedly taking sides with the super powers like USA, UK and USSR. Another war will result in total destruction of the world. But regional conflicts are on the rise, threaten world peace, and the unexpected conflagrations can not be ruled out. T herefore, the legal arguments for humanitarian intervention, is necessitated and the world leaders have no other option but to pursue it vigorously. The book highlights the lack of international intelligence system to facilitate the global converge and public education required to mobilize and sustain multi-national peacekeeping operations. From the financial perspective, UN peace keeping operations depend upon the funding by the contributing nations. Whether they will provide the incremental assistance required during the big peace-keeping operations

Erupted Material Essay Example for Free

Erupted Material Essay Another way of classifying volcanoes is by the composition of material erupted (lava), since this affects the shape of the volcano. Lava can be broadly classified into 4 different compositions (Cas Wright, 1987): * If the erupted magma contains a high percentage (63%) of silica, the lava is called felsic. * Felsic lavas (dacites or rhyolites) tend to be highly viscous (not very fluid) and are erupted as domes or short, stubby flows. Viscous lavas tend to formstratovolcanoes or lava domes. Lassen Peak in California is an example of a volcano formed from felsic lava and is actually a large lava dome. * Because siliceous magmas are so viscous, they tend to trap volatiles (gases) that are present, which cause the magma to erupt catastrophically, eventually forming stratovolcanoes. Pyroclastic flows (ignimbrites) are highly hazardous products of such volcanoes, since they are composed of molten volcanic ash too heavy to go up into the atmosphere, so they hug the volcanos slopes and travel far from their vents during large eruptions. Temperatures as high as 1,200 Â °C are known to occur in pyroclastic flows, which will incinerate everything flammable in their path and thick layers of hot pyroclastic flow deposits can be laid down, often up to many meters thick. Alaskas Valley of Ten Thousand Smokes, formed by the eruption of Novarupta near Katmai in 1912, is an example of a thick pyroclastic flow or ignimbrite deposit. Volcanic ash that is light enough to be erupted high into the Earths atmosphere may travel many kilometres before it falls back to ground as a tuff. If the erupted magma contains 52–63% silica, the lava is of intermediate composition. * These andesitic volcanoes generally only occur above subduction zones (e. g. Mount Merapi in Indonesia). * Andesitic lava is typically formed at convergent boundary margins of tectonic plates, by several processes: * Hydration melting of peridotite and fractional crystallization Sarychev Peak eruption, Matua Island, oblique satellite view * Melting of subducted slab containing sediments[citation needed] * Magma mixing between felsic rhyolitic and mafic basaltic magmas in an intermediate reservoir prior to emplacement or lava flow. If the erupted magma contains 45% silica, the lava is called mafic (because it contains higher percentages of magnesium (Mg) and iron (Fe)) orbasaltic. These lavas are usually much less viscous than rhyolitic lavas, depending on their eruption temperature; they also tend to be hotter than felsic lavas. Mafic lavas occur in a wide range of settings: * At mid-ocean ridges, where two oceanic plates are pulling apart, basaltic lava erupts as pillows to fill the gap; * Shield volcanoes (e. g. the Hawaiian Islands, including Mauna Loa and Kilauea), on both oceanic and continental crust; * As continental flood basalts.

The Effects of Transmissible Spongiform Encephalopathies on Humans Essa

The Effects of Transmissible Spongiform Encephalopathies on Humans Abstract Humans have to deal with many different diseases and the ones most disliked are the ones with no cures. Like cancer, transmissible spongiform encephalopathies have no cure, but they are more rare. These diseases are prion diseases which cause the brain to deteriorate. Prions are proteins that sometimes behave like viruses, which mean that they should have some form of nucleic acid, but since they don’t, they cause abnormalities. The nervous system contains many normal prions, but when an abnormal prion comes along, it transforms all the normal prions into abnormal ones. Bovine spongiform encephalopathy is found in cattle, but it can be transmitted to humans. The Creutzfeldt-Jakob disease affects the elderly for reasons unknown, while Kuru affects those who practice cannibalism. Scrapie is found only in sheep and the Chronic Wasting Disease is found in deer and elk. As of right now, Kuru and Scrapie are not known to infect humans. Prion diseases affect many animals, such as cattle, sheep, deer, elk and humans. All mammals have prions, which are proteins that are found abundantly in the nervous system. The brain contains the most prions and is therefore dominantly affected by disease. The prion disease found in cattle is called bovine spongiform encephalopathy, or mad cow disease. Humans contract this disease by eating infected cows. The elderly usually contract the Creutzfeldt-Jakob disease for reasons unknown, and Kuru, which is extremely rare nowadays, is contracted by cannibalism. Scrapie infects sheep and the Chronic Wasting Disease infects deer and elk. Though there is no link to either Scrapie or Chronic Wasting Disease infecting humans, it is ... ...missible Spongiform Encephalopathies 6 References †¢ American Veterinary Medical Association.

The Leadership of Pres Kennedy and Johnson

Kennedy wasn†t in office for very long, his actions in and out of the whitehouse are legendary. When President Kennedy took the oath of office in 1960 he wasted no time in cleaning up America. Several bills were enacted in President Kennedy†s tenor. A lot of the major ones had to do with crime control. A lot of President Kennedy†s bills were targeted at organized crime. Bill S1653 was singed into action on September 13 1961. This was an interstate travel bill. The bill made it a crime to travel or use any facilities in interstate commerce with intent to conduct violent crimes to further illegal gambling, liquor, narcotics, or prostitution business. This bill had a major effect shutting down a lot of â€Å"speakeasy†s† which took care of gambling, and betting. Customs got a lot tighter which had a great impact on the running of liquor to foreign countries such as Canada and Mexico. A lot of drug pushers were arrested and many Bordellos† were also shut down. The senate passed Bill S1653 on July 28 and House on Aug 21. This was one of many anti-crime Bills that President Kennedy would enact throughout his term. A lot of his primary goals were oriented towards organized crime. Another one of President Kennedy†s crime Bills to be passed in 1961 having to do with crime was Bill S1656. This Bill made it a crime for anyone in the betting business to knowingly use a wire communication facility to transmit in interstate commerce any bets or wager information. Also it made it a crime to be caught with any betting paraphernalia such as parley sheets or wager stubs. This authorized a lot of wire-tapping and surveillance. Bill S1656 was passed by the Senate on July 28 and by the house on August 21 and was signed September 13. One other bill passed in 1961 by President Kennedy was the Fugitive felon act. This act made it a federal crime to cross boarders to avoid being prosecuted or remanded into custody after committing a violent crime or avoid giving testimony on a crime. This act was strongly enforced by local law enforcement agencies. The Federal firearms act of 1961 was a major bill passed for President Kennedy in 1961. This act prohibited the shipment of firearms in interstate and foreign lands to people under inditment for certain crimes. Not all of President Kennedy†s bills were directed towards the Mob and other such crime syndicates. President Kennedy also lobbied for the 1961 juvenile delinquency and youth offences control act. This act provided programs of federal assistance to state and local agencies to control delinquencies. It also authorized sections of health, education, and welfare to make grants for projects to improve methods of control, treatment and prevention of delinquency and to establish personal training programs. This bill was mainly focused at gang members, drug addicts, and first time offenders under the age of eighteen. In 1962 President Kennedy continued his onslaught on organized crime. One of his first acts was to enact an anti-crime bill that put a stop to interstate travel of gambling machines. Bill S1658 broadened on the 1951 ban on interstate travel of gambling machines to include shipments to points in the U.S. through foreign commerce and any machines including roulette wheels. Roulette wheels were included simply for the fact that they are a machine that is wagered upon were the course of action can result in the transfer of currency and or property. This bill was ironically called the Gambling Devices act of 1962. The Senate passed this bill by voice vote on July 27, 1961 and by the House June 29. This Bill was then signed into law October 18, 1962. Another bill that was going through congress was the eighth in a package of anti-crime bills proposed in 1962. Only two of the bills actually got anywhere. They were bills S1658 (the gambling machine bill) and bill S1655. This bill allowed the granting of court immunity to certain witnesses in labor-management racketeering cases. The Senate passed this in 1961. After president Kennedy was assassinated on November twenty-second, 1963, Vice-president Johnson was sworn into office at 2:38 PM later that day. President Johnson picked up where his predecessor left off. This led to the creation of a presidential committee on youth crime and juvenile delinquency with major stress on major cities such as New York, New Haven, San Francisco, and Cleveland. Other provisions to this act that differed from the first are setting up detoxification centers for drug abusers. One of his major acts was appealing to congress for drug laws and punishment. In 1964 a bill went through congress stating that there wasn†t â€Å"adequate means for detecting illegal diversions (of psychotoxic drugs) from legitimate channels. The reason for this bill was to make the non-legit licensed drug pushing a federal crime. One of the problems was that for the bill to be effective the regulation of such drugs had to cover intrastate as well as interstate commerce. The reason congress had to do this was because the drugs themselves do not come with labels stating their origins, and because of the manor that the drugs are held and or consumed a placing of their origin could be very taxing. For example because of foreign commerce certain drugs from for example Columbia might be treated more or less over say Peru. On August fifteenth 1964 congress passed bill number S 2628 by voice vote. There was no objection to the bill. The narcotics bill passed through congress and was eventually signed by President Johnson. On a related note the previous bill was the only directly involved narcotics bill in 1964. Around the same time that the narcotics bill was going through congress, the Senate Juvenile Delinquency Subcommittee filed a report on August 31. The report basically stated that the Narcotics Control Act of 1956 wasn†t working. The committee stated that â€Å"it failed in its initial determent purpose.† To help solve the problem the subcommittee recommended passage of several legislative measures. One of the bills was S 2628 this bill stated that instead of sentencing addicts, the way to handle them was to set up hospitals and detoxification centers. This was the new way to handle drug abusers. In 1965 President Johnson began to take a look at an increase in Mafia action that has been on a steady incline since 1961. In 1965 several bills were formed to combat organized crime. Senator†s John L McClellen (DArk) and Senator Frank J Lausche (D Ohio) submitted four bills in a package on June 24. The bills were as follows: 2187: Made it illegal to be involved in Mafia or any â€Å"secret society† that made their living by committing criminal activity. 2188: Made it a crime to obstruct federal procedures or investigations by attempting to bribe officials involved or witnesses. 2189: Legalized certain wire-tapping by federal agents for violation of federal law. 2190: Permitted witness in federal grand jury investigation to be compelled to testify and provide that they could be granted immunity from prosecution based on their compelled testimony. In early August of 1965, President Johnson urged for the enactment of the Law Enforcement Assistance Act of 1965 to supplement federal law training to local law enforcement officers as the FBI had conducted in the past. The purpose of the act was to provide training programs and demonstration projects in police work to update and improve the standards of local law enforcement personnel. The house passed on August 2, bill HR 8207 which authorized an appropriation of ten million dollars to implement the act in fiscal 1966. In 1967 the Omnibus District of Columbia Crime bill was passed which provided for warrentless arrests for minor misdemeanors and issuance of summons. In addition President Johnson also established a Federal Judiciary center to improve the operation of the federal judiciary and for protecting witnesses and informants from such enemy†s like the mob or other syndicated crime organizations. The Safe Streets and Crime Control act was passed to provide money for research and education for many ordinary street crimes. This set up the pathway for local organizations such as neighborhood watch. An Addition to that act was to focus again on juvenile crime. Thus the Juvenile Bill of 1967 was adopted. This bill also provided more money to develop and improve existing facilities regarding juvenile crimes. The money that was given went to: A. Appoint the Commission on crime and delinquency to do research on crime in the U.S. B. Appoint the Commission on law enforcement and administration of justice. A major contribution to the growing violence in America was guns. President Kennedy didn†t touch much on gun control. Neither did President Johnson until 1968. In 1968 President Johnson signed the gun control act. This act stated that a better control of interstate traffic in firearms was needed. This bill enabled support to federal, state and local law enforcement officials in their fight against violence and crime. President Johnson wasn†t only interested in fighting injustices on earth. Also in 1968 he signed an agreement between the U.S. and USSR banning nuclear weapons in outerspace. In conclusion President Kennedy and President Johnson both did a lot for crime control. A lot of the bills and act in which they personally oversaw are still in use today. Both had a lot to say and put their words into action. A lot of attention may have been swayed during the Johnson administration due to Vietnam. But President Johnson didn†t allow this to focus here at home as well. A lot has been done to prevent crime. A lot still needs to be done. With a little faith our presidents will continue to sign bills that will keep our streets safe and take care of crime in America. It isn†t very easy to get a bill to become a law. Most proposed bills never leave the floor before they are thrown out. Only the bills that have strong effects and are truly needed become laws in America.
