A science column - Essay ExampleWe aim to charge our cell phones whenever they are exhausted of energy/power. This we have to do by using galvanizingity and we wonder how electricity and the cell phones are related to such that we are able to communicate with people far away from us once the twain have been fused together. Sometimes, we have magnets which attract original things such s iron materials and other types of magnetic materials. We wonder where such force of attraction is originating from inside the magnet, just a piece of steel or iron. All these fascinations are the results of certain discoveries made some time back in the history of science and have been integrated over time to bring in some ways which actually make life easier and convenient. The relationship between electricity and magnetism can be traced back to the times of the superior scientists who contributed so much to the development of electricity ad electric discoveries such as Michael Faraday and Ampe re. This paper will look at the integration between the two laws create by Michael Faraday and Ampere to explain the relationship between electricity and magnetism. Michael Faraday substantial a law which tried to explain this relationship by design a connecting line between electric transfers and magnetism. The laws can be defined in terms of electromotive force (emf), the force believed to be the driving force of an electric current, as Faraday notes. The law states that A time- changing magnetic flux though a closed circuit induces an emf in the circuit. (Sadiku) Faradays electromagnetic generality can be divided into two laws which are however related to each other and tries to explain the flow and the induction of magnetism in a substance. The first law states that whenever a conductor is placed in a varying magnetic field, an emf is induced which is called the induced emf, if the circuit is closed, current is likewise induced which is called the induced current. (Sadiku) The second law states that the induced emf is equal to the rate of change of flux linkages whereby the flux linkage is the product of the number of turns of the coils n and the flux associate with it. (Sadiku). According to this law, the number of turns in the coil will then determine the amount of current flowing through the wire and wickedness versa as shown in the diagram. This emf only last as long as the magnetic current within the circuit continues to change. In this way Faraday developed a law which describes the electromagnetic induction whereby, an electric field is usually induced or created by a changing magnetic field. When current flows in a solenoid wounded around a magnetic material, the material becomes magnetized and this creates the potential difference. It is this difference which keeps the current flowing from one point to another. The emf developed is the force that works against the electric potential commonly referred to as the voltage. The common voltage in dry cells is 1.5 and has the electric potential moving from the positive electrode t

A Culture of Safety Essay Example | Topics and Well Written Essays - 1250 words

A Culture of Safety - Essay ExampleHowever, as management models have continued to evolve, people have recognized that an erroneousness apprise only be prevented if it is known. This is the basis of the just culture in nursing, which acts as a bridge between the traditional approach and a berth in which no one bears the responsibility of errors. The just culture enables an organization as well as its employees to learn from mistakes and create a system that minimizes chances of error. This newspaper explores the just culture in a nursing setting and its impact on the safety of the patients. The Role of the Nurse in refering Potential and Real Threats forbearing safety is the core mission of every healthcare institution. Nurses have a role in ensuring that the patients in a hospital setting are catered to adequately to ensure their safety. They are obligated to identify, whenever possible, the risks that patients face while in the health institution. One way of identifying threat s against the health of a patient would be to open the confabulation channels in the hospital. This would enable a nurse to report to the administration about a threat to the safety of the patients. Previously, the punitive system in such a setting inhibited such reporting and nurses only identified threats which they would not be able to hide. The just culture enables a nurse to identify a risk which may have occurred due to an error and report the threat in the appropriate manner. This increases patient safety as adequate measures can be taken to remedy the situation. This role of the nurse is, therefore, in line with the just culture as proposed by Reason (American Nurses Association, 2010). Steps in Minimizing or Eliminating Threats Rules and Regulations Following instructions that are set by the organization should be a priority for all nurses. Managers, according to Lazarus (2011), must put systems in office staff that will enable the nurses to carry out their roles in the institution effectively. These systems are part of the rules that are set by the nursing leadership to provide upper limit efficacy at the work trust. Nurses should therefore adhere to these set rules and regulations, in order to minimize the chances of errors happening at the work place. Most of the systems in place are tested and tried, meaning they have been found to reduce the number of errors that people can make at the work place. Although human errors do occur, a continuous improvement of the system, as proposed in the just culture will lead to the system achieving maximum efficiency. Acting with regard to these rules will minimize or even eliminate the chances of error. Nurses should only act contrary to these rules when there is evidence that acting according to them presents a threat to the patient (Lazarus, 2011). Attending Seminars Seminars and other meetings organise by the institution to sensitize employees in patient safety are a valuable resource to nurses. Policie s that are proposed and passed during these meeting have an effect on the performance of the nurses, and it is therefore important that nurses attend these meetings. This way, they will be conversant with the rules and regulations, as well as contribute to the development of these policies such that the rules will in addition be in favor of the nurses. Patient safety can be maximized through such meetings since the stakeholders agree on the most effective means of achieving that goal. Nurses loosely deal with patients directly and are obligated to ensure the safety of the patient. By attending these seminars, they increase their knowledge and learn how to incorporate the new policies with their expertise. This is an important grimace for the safety of the patient and nurses should take this measure to minimize threats to

IP Addressing and Subnetting Essay Example | Topics and Well Written Essays - 1250 words

IP Addressing and Subnetting - Essay ExampleThese identifiers are the one referred to as the profit communications protocols which are numerical figures that identifies a device connected to a network. IP conducting therefore means assigning these figures to a device so that it can be identified. On the other hand a sub network, also known as subnet is a sub division of an IP network, which makes sub netting to be the division of an IP network (Blank 2004). There exists two main versions of internet protocol which include internet protocol version 4 (IPv4) and internet protocol version 6 (IPv6).since these versions contain an endless pools of numbers, for IPv4, this pool of numbers is 32 bits written as (232) and contains 4,294,967,296 IPv4 addresses, where bits refer to a digit in the form of binary star system which is use in storing information. For IPv6 version, it has 128-bits written as (2128) containing 340,282,366,920,938,463,374,607,431,768,211,456 IPv6 addresses. These two versions are assign to a given network in different sizes. The size assigned is shown after an oblique, and it reflects the number of IP addresses contained in it. The lower the number after the oblique the more the number of addresses the protocol size has (Groth 2005). Since an internet protocol is do up of 32 binary bits, they are subdivided into network and host sections. The network portion identifies the particular network that it is connected to whereas the host portion identifies a node, be it a computer, on the local area network (LAN). This is aided by the use of subnet mask, which is described as a 32 binary bits combination that is these octets used to show which section or portion of an IP address refers to a subnet and the other tat refers to the host. The 32 binary bits are subdivided onto octets where octet holds 8 bits qualification a total of four octets. These octets are then turned into decimals and separated by a period. This is why an IP address is expr essed in decimal with dots in between. The number of decimal in each octet ranges from 0-255 decimals or 00000000-11111111 binary (Groth 2005). As indicated above, a subnet mask helps to know which section of the internet protocol identifies a given network and the section of the IP that identifies the nodes. If we have a network with a natural mask of 255.0.0.0 which has not been sub netted, it would have an address close to 8.20.15.1255.0.0.0.converting these addresses and masks to binary numbers, and we would have 8.20.15.1 = 00001000.00010100.00001111.00000001 255.0.0.0 = 11111111.00000000.00000000.00000000 There different types of IP addressing and each have their own features. One of the forms includes the unicast. This is the most used concept of internet protocol addressing for both IPv4 and IPv6.it is used to refer to a single venter and a single receiver which could be used for sending and receiving. A unicast address is normally for a single host. Different devices have different unique unicast addresses, each with a different unique purpose. This means that for a person to data to numerous unicast addresses, he is required to send it many times to each recipient. The second type of IP address is the broadcast. Only IPv4 implements the broadcast addressing since IPv6 replaces broadcast with multicast addressing. For the IPv4, it is with ease to send data to all hosts. In the IPv4 address the address 255.255.255.255 is used to broadcast. The third type of addressing is the multicast addressing. Multicast address is linked with a group of recipient. For IPv4 addresses, given addresses 224.0.0.0

State-Supported Terrorism Assignment Example | Topics and Well Written Essays - 750 words

State-Supported Terrorism - Assignment ExampleThese are the nations that pose a threat to the US National Security, although Saudi Arabia and Pakistan also hap under the same list of passive sponsorships but regardless to their betivities they are excluded out deliberately.In article 3 the writer, Daniel Byman has identified the states that are passively sponsoring terrorist organizations nearly the world. The states that are prominently known for their support are Saudi Arabia, Pakistan, Iran, and Lebanon. These states in order to strengthen their security jeopardize the National Security of US and soak up societies into the darkest propensities. It is a widely known fact that 9/11 was orchestrated with the help of Saudi Arabia of which funding transactions were traced evidently displaying Saudi Arabias inexplicit terrorist sponsorship for destroying US security. Likewise, Pakistan is held responsible for the Talibanization within the country, as the members of its intelligence ISI are in full support of Al-Qaeda. These countries which are referred to as non-state actors stay at the corner, some whitethorn as well agree on fighting terrorism becoming invaluable allies for the time being. The enigma is not with their attitude of doing something instead its their attitude of doing nothing at all about the prevailing threats to the national security.One way these states react to these problems is that they offer a middle ground to the problem to safeguard their own security they shift their problem to others by offering the terrorists to stay and get arrested or leave which moves them to other countries where they perform acts of terrorism. These terrorist groups often act as governments partners and not as their agents, although they openly deny the accusations it is evident with the size of their training setups, their methods of recruitments and funding.

Major Theological Divisions in the Islamic World Research Paper

Major Theological Divisions in the Moslem World - Research Paper ExampleThe purpose of this paper is to establish the origins and evolution of the major divisions in Islam, and identify their ideologies and historical significance until the period of the Mongol Conquests. The paper argues that the major divisions of Islam were caused by struggles for power and authority, and evolved over a long period of snip starting in the eighth century after the death of Prophet Muhammad. The major Islamic divisions include Sunni, Shiite, Wahhabis, and Suffis.As the discussion stresses Prophet Muhammad had predicted in his vox populi time that the Islamic religion would divide into seventy-three sects, which would all go to hell except himself and his true followers. The Islam divisions ar now up to 150. The first Islamic group which was a successor of Prophet Muhammad was formed immediately after the death of the prophet in the seventh century. This division is known as the Sunni Muslims. S unni Muslims are the majority of Muslims in the world, and they follow the four Khalifs who succeeded Prophet Muhammad Hanifa, Hannibal, Malik and Shafi. This group has evolved to pursue their religion alongside secular societies. Ansary suggests that they have followed the three Islamic sources of law namely, Hadith, ledger and Muslim consensus. They consider themselves as those who have been saved by Allah hence deriving the title of Najiyah.

Cultural Differences Study Of Brazil, China, And Nigeria Essay

Cultural Differences Study Of Brazil, China, And Nigeria - Essay ExampleThis can be a big challenge given the presence of numerous languages from Chinese mandarin orange tree to Brazilian Portuguese, the best way to deal with this is to have an all inclusive mode of communication that can be understood across the board and makes certain(predicate) all the stakeholders understand what is expected of them.Considering the opportunities and the challenges that have been outlined earlier in this report it is important for the company to adapt to the cultural needs of these countries. These three countries all(prenominal) have their own way of doing business and the best approach should not be a general approach. In China and Nigeria, there exist handed-down values that maintain the hierarchal system and all these factors have to be considered when coming up with a management system that fits all these different cultures. At the main office, the workers have a lot of freedom and freely interact with their superiors. The opportunities are an indication that the company should expand to these areas to take advantage of these factors, however, the challenges should also be considered and ways to tackle them clearly established. This is because they may prevent the growth of the business in these markets if they are not properly dealt with at the beginning. This process should be interpreted as a learning process and should be done carefully so that all the expected results are achieved. There should be different approaches to add for these three different cultures because people in these countries react differently to information.

Censoring Pleas for Help Essay Example for Free

illegalize Pleas for Help EssayIn Dwight Lees essay, Censoring Pleas for Help, the Georgia-based economics professor notes the strange contradiction among popular opposition to censorship and widespread support of price controls. Lees primary list with this political dissonance is that it is not only ethically inconsistent, but reflects an oversight of how markets ease give-up the ghost economic needs, particularly with regards to the sudden needs which emerge in the wake of natural disasters.Much of the support for price controls stems from fear of price gouging, which is essentially occurs when suppliers attempt to take advantage of sudden demand by natural elevation prices to maximize profit during the period of demand. Lee notes that in his home state, there exists a price gouging law which is designed to prevent such a station from happening by forbidding suppliers from charging more for their goods than they did the day before a disaster strikes. Lee notes that buil ding contractors and construction supplies from several states had poured into Atlanta immediately aft(prenominal) it suffered massive tornado damage. Can anyone seriously believe that this help would have poured in from far away if the price gouging law had been perfectly enforced, or that the help was not reduced by the enforcement that had occurred? (Lee 1999)The crux of Lees argument is that price controls are essentially a form of economic censorship which restricts the faculty of prices to communicate market demands. To that end, he argues that prices are better understood as the most efficient means by which markets, such as disaster victims, communicate their need for help in the form of resources and supplies.This is not to devalue the contributions and assistance that some have provided for free, but the economic distinction made above between humanitarian aid and supply-demand response is not a trivial one. While those who provide supplies for free are to be commended, it is important to recognize the potential mistake in relying on altruism and humanitarian sensitivity as the primary forces driving resource redistribution.Such a view presumes that humanitarian aid is an accusatory force that responds to the needs of disaster victims efficiently. In effect, Lees argument is that while high prices should not be raised to wildly disproportionate levels, allowing them to waver free of price controls ensures that they can communicate needs more efficiently, for high prices insure that pleas for help will be met with a quick and effective response. complemental to his point, Lee observes that price controls censor this economic communication and effectively disrupt the ability of customers to express their needs. He notes that in Charleston, price controls prevented a local computer ironware store from legally being able to sell generators at a higher price nor could the locals communicate their demand to outside suppliers of generators. The result was that one hardware store owner sold one of only two generators in his possession to a friend, at the expense of groceries with a greater demand in the form of thousands of dollars worth of food that needed refrigeration.Simply put, humanitarian aid relies on the initiative of those with the resources and the sense of philanthropy to contribute to disaster relief, which is all salutary and good, but does not compare to the efficacy of free moving prices in expressing the demands that emerge in the wake of a natural disaster. As far as economics are concerned, price controls merely censor the ability of these sudden emergent markets to communicate those demands.Works CitedLee, Dwight R. Censoring Pleas for Help.
