There are two categories of the power techniques (Tesla and Childress, 2010). These power techniques include radiative and non-radiative. The non-radiative techniques apply the mechanism where the power is transmitted or transferred over very short distances through the magnetic fields by use of inductive coupling techniques between the wire coils. The application of this technology is applied in chargers of toothbrush, smart cards, RFID tags, and the chargers of the medical devices that are implanted such as the cardiac peacemakers and the inductive charging and powering of vehicles. The primary focus is come up with a wireless system that can recharge the handheld gadgets and mobile devices like digital music players, cell phones, and portable computers, which are tethered, to a plug on the wall. The radiative technique is also referred to as the power beaming where the power is transferred by the mechanism of the beams of radiation of the electromagnetic. This aspect applies to the microwaves and laser beams. The technique can transmit energy to longer distances as compared to the non-radiative technique. The energy should always be aimed at the receiver. The applications that are proposed for this technique are in the use of solar power satellites and can be utilized in the drone aircraft that are wireless powered. A crucial issue that is associated with the wireless systems of the power is the limiting the peoples exposure and the living things that might come into the path of the radiation. The radiation contains potentially harmful effects. Many engineers and designers have faced significant challenges that have involved the power. Some of the challenges are the continuity of the power supply, optimizing the sensor locations, battery recharging

The Effects of Smoking on the Developing Fetus Essay -- Health Medical

The Effects of Smoking on the Developing Fetus The exposure of the fetus to nicotine during development has several effects. The most well known result of smoking is low birth weight of the infant. There are also some studies that reveal nicotine as a drug that can affect the brain of the developing fetus. Nicotine also has direct effects on the neurotransmitter systems in the CNS and may cause a decrease in cell growth which could result in mental impairment. The correlation between maternal smoking and low birth weight has been strongly established. Nicotine affects the placental function by inducing the release of norepinephrine and epinephrine into the maternal blood, which causes decreased blood flow to the placenta (1). The decreased blood flow causes a decrease in delivery of oxygen and nutrients to the fetus. This may have an effect on cell growth and development. High levels of carboxyhemoglobin are present in the blood of the mother and the fetus. This may decrease the capacity of the blood to transport oxygen and fetal hypoxia is the result (2). Fetal hypoxia and ischemia are major contributors to developmental defects, but nicotine has been implicated, in various studies, to have a direct affect on fetal development (3). Several studies suggest that nicotine interferes with cell acquisition and development in various brain regions. The developing nervous system seems to be more vulnerable to nicotine exposure than the rest of the body (4). This is important since nicotine readily crosses the placental barrier and fetal blood concentrations are equal to or above that of the mother (1). DNA can be used as a index for measuring cell acquisition. An experiment on rats by Lichtensteiger et. al. reported that DN... ...r.

Lord of the Flies: The end of innocence Essay

Lord of the Flies. ‘The end of innocence and the darkness of man’s heart.’ Do you agree that these are the central concerns of Golding’s novel? Please justify your answer making close reference to the text. In his novel, Lord of the Flies, Golding raises the issue of ‘the end of innocence and the darkness of man’s heart’ in his portrayal of certain characters. However, he contrasts such characters with those who possess the human spirit, that is, a humanity and decency that can survive the most extreme circumstances. By contrasting characters of Jack and Ralph, Golding raises the theme of good versus evil, loss of innocence, the struggle for power and his central concern seems to be that there is a thin veneer between civilised man and the savage. Though Ralph turns out to be a good leader because of his moral principles, initially the boys choose him over Jack because of his appearance: â€Å"you could see now that he could have made a boxer†. However, as leader, Ralph is faced with adult problems which force him to lose his innocence and develop as a character. For example, Ralph reveals Piggy’s name to the others after Piggy had asked him not to, but he experiences empathy towards him: â€Å"Ralph, looking with more understanding at Piggy, saw that he was hurt and crushed. This causes him to mature and treat Piggy with more respect. Ralph attempts to maintain order among the boys by constructing a set of rules. For example, the fact that one must be holding the conch to speak. The conch represents a sense of order and democracy among the boys and Golding describes it as ‘precious’ and ‘valuable’ yet ‘fragile’. The fact that the rules get ignored gives a sense that Ralph is losing power and the boys are gradually deteriorating into savages. The idea of the loss of order is reinforced by Golding when Ralph notices that the conch is â€Å"losing its shine.† By the end of the novel, Ralph is the only one not to degenerate into a savage and retains his dignity. This is demonstrated when Samneric wanted to wear paint but Ralph refused to wear it: â€Å"we won’t wear paint because we’re not savages.† His fight for good against evil leads him into a situation quite beyond him because the standards he represents are crushed in a world run by Jack’s kind of rules. Jack epitomizes the corrupt dictator in society. From the very beginning he is illustrated as a sinister character through Golding’s use of diction such as ‘dark’, ‘shadow’ and ‘evil’. He also shows malice towards Piggy, shutting him up when he’s got the conch: â€Å"Shut up’ fatty!† this shows his disregard of the rules which pushes him to savagery. On the expedition around the island he found a piglet. Jack was on the point of killing it when he realized the â€Å"enormity the downward stroke would be† and let it get away, but afterwards he said, â€Å"Next time there would be no mercy† which is a turning point for Jack as he is now prepared to kill. The image of the pig can be linked to the character, Piggy, and Jack’s determination to kill the pig foreshadows his murder of Piggy. This is ironic since Jack was introduced as a choirboy and it reveals that we are all capable of evil. Unlike Ralph, Jack degenerates as a character, becoming an â€Å"ape-like† savage with a lust for killing. He attempts to assert his power and abolish the order when he tries to eliminate the need for the conch: â€Å"We don’t need the conch anymore.† After he becomes chief, he abuses his power. For instance, he makes his seat into a ‘throne’ and he takes Piggy’s glasses by force: â€Å"You came around like a thief and stole Piggy’s glasses.† He also managed to corrupt the others through his use of paint: â€Å"the mask compelled them† and the reward of meat. Golding’s central concern seems to be that there is a thin veneer between civilised man and the savage. He shows us that â€Å"the end of innocence and the darkness of man’s heart† is not applicable to everyone in the novel, for example, Ralph, Piggy and Simon are good characters, who possess the human spirit, in that their humanity and decency survive under the most extreme conditions. By contrasting characters, such as Ralph and Jack, Golding raises themes of good versus evil, loss of innocence and the struggle for power.

How to Write and Format a Business Case Study

Business case studies are teaching tools that are used by many business schools, colleges, universities, and corporate training programs. This method of teaching is known as the case method. Most business case studies are written by educators, executives or heavily educated business consultants. However, there are times when students are asked to conduct and write their own business case studies. For example, students may be asked to create a case study as a final assignment or group project. Student-created case studies may even be used as a teaching tool or a basis for class discussion. Writing a Business Case Study When you write a case study, you must write with the reader in mind. The case study should be set up so that the reader is forced to analyze situations, draw conclusions, and make recommendations based on their predictions. If you arent overly familiar with case studies, you may be wondering how to best organize your writing. To help you get started, lets take a look at the most common ways to structure and format a business case study.   Case Study Structure and Format Although every business case study is a little different, there are a few elements that every case study has in common. Every case study has an original title. Titles vary but usually include the name of the company as well as a little info about the case scenario in ten words or less. Examples of real case study titles include Design Thinking and Innovation at Apple and Starbucks: Delivering Customer Service. All cases are written with a learning objective in mind. The objective might be designed to impart knowledge, build a skill, challenge the learner, or develop an ability. After reading and analyzing the case, the student should know about something or be able to do something. An example objective might look like this: After analyzing the case study, the student will be able to demonstrate knowledge of approaches to marketing segmentation, differentiate between potential core customer bases and recommend a brand positioning strategy for XYZs newest product. Most case studies assume a story-like format. They often have a protagonist with an important goal or decision to make. The narrative is usually weaved throughout the study, which also includes sufficient background information about the company, situation, and essential people or elements. There should be enough detail to allow the reader to form an educated assumption and make an informed decision about the questions (usually two to five questions) presented in the case. The Case Study Protagonist Case studies should have a protagonist that needs to make a decision. This forces the case reader to assume the role of the protagonist and make choices from a particular perspective. An example of a case study protagonist is a branding manager who has two months to decide on a positioning strategy for a new product that could financially make or break the company. When writing the case, it is important to ensure that your protagonist is  developed and compelling enough to engage the reader.   The Case Study Narrative/Situation The narrative of a case study starts with an introduction to the protagonist, her role and responsibilities, and the situation/scenario that she is facing. Information is provided on the decisions the protagonist needs to make. Details include challenges and constraints related to the decision (such as a deadline) as well as any biases the protagonist might have. The next section offers up background information on the company and its business model, industry and competitors. The case study then covers challenges and issues faced by the protagonist as well as the consequences associated with the decision that the protagonist needs to make. Exhibits and extra documents, like financial statements, might be included in the case study to help students reach a decision about the best course of action.   The Deciding Point The conclusion of a case study returns to the main question or problem that must be analyzed and solved by the protagonist. Case study readers are expected to step into the role of the protagonist and answer the question or questions presented in the case studies. In most cases, there are multiple ways to answer the case question, which allows for classroom discussion and debate.
