Series-Parallel Circuit - Essay Example Rather, it contains elements of both. The current exits the bottom of the battery, splits up to travel through R3 and R4, rejoins, then splits up again to travel through R1 and R2, then rejoins again to return to the top of the battery. There exists more than one path for current to travel (not series), yet there are more than two sets of electrically common points in the circuit (not parallel). Because the circuit is a combination of both series and parallel, we cannot simply apply the rules for voltage, current, and resistance. For instance, if the above circuit were simple series, we could just add up R1 through R4 to arrive at a total resistance, solve for total current, and then solve for all voltage drops. Likewise, if the above circuit were simple parallel, we could just solve for branch currents, add up branch currents to figure the total current, and then calculate total resistance from total voltage and total current. However, this circuit's solution will be more complex. To calculate the different values for series-parallel combination circuits, we'll have to be careful how and where we apply the different rules for series and parallel. Ohm's Law, of course, still works just the same for determining values. And then, we become able to identify which parts of the circuit are series and which parts are parallel, we can...

And then, we become able to identify which parts of the circuit are series and which parts are parallel, we can analyze it in stages, approaching each part one at a time, using the appropriate rules to determine the relationships of voltage, current, and resistance Note: The rules of series and parallel circuits must be applied selectively to circuits containing both types of interconnections. Technique Analysis The goal of series-parallel resistor circuit analysis is to be able to determine all voltage drops, currents, and power dissipations in a circuit. The general strategy to accomplish this goal is as follows. Step 1: Assess which resistors in a circuit are connected together in simple series or simple parallel. Step 2: Re-draw the circuit, replacing each of those series or parallel resistor combinations identified in step 1 with a single, equivalent-value resistor. Step 3: Repeat steps 1 and 2 until the entire circuit is reduced to one equivalent resistor. Step 4: Calculate total current from total voltage and total resistance (I=E/R). Step 5: Taking total voltage and total current values, go back to last step in the circuit reduction process and insert those values where applicable. Step 6: From known

Approaches for Improving Disaster and Emergency Preparedness Planning Processes and Procedures in a System - Research Paper Example The paper primarily focuses on planning processes and procedures in a system-based framework. Emergencies often occur because of lack of proper systems or failure of the existing systems to limit, control and prevent the circumstances that trigger incidences that cause disasters. Emergencies are common in any given area: in schools, churches, towns, offices and roads. One of the characteristics of emergencies is that they are not predictable; they hit any time when people are not expecting them. This unpredictability character has forced the stakeholders of areas prone to emergencies and disasters to prepare mitigation mechanisms that they can apply to limit the adversities associated with unforeseen circumstances. The purpose of this research paper is to help people to understand the critical aspects of disaster preparedness and emergency mitigation measures. Emergencies that organizations and people predict and prepare for in advance have lesser adversities than those that are unpr epared for or in terms of planning. It is crucial for the citizens to understand the processes and procedures for mitigating disasters and emergencies in their environments. ... A disaster results in significant physical damage, destruction, loss of life and drastic change in ecosystems (Arthur, 2007). Disasters are tragic events arising from undesirable events such as catastrophic accidents, explosions, earthquakes, fires, and floods. An emergency constitutes a situation that poses an immediate danger to property, health, environment, and life (Karagiannis, Piatyszek & Flaus, 2013). Emergencies require urgent intervention to act as countermeasures for preventing the worsening of the risk. Emergency preparedness is a long-term program involving activities whose aims are to strengthen the capacity and capability of a community to manage efficiently all types of emergencies and ensure an orderly transition from relief through recovery and sustainable development. Most countries have set government emergency services to respond to emergencies; these agencies are responsible for planning and managing emergencies. Emergencies and disasters can cause both mild and devastating damage. The preparedness and planning for these disasters and emergencies is of paramount necessity at all times. A system-based framework is a structure of operation where several independent units are interrelated to work together towards achievement of a common goal. A system-based framework is characterized by environment, feedback, boundaries, controls, inputs and outputs (Sommer & Nja, 2012). Disaster and emergency preparedness approaches are necessary in a system-based framework to a countermeasure the adversities of the risks. Statement of the Problem Major emergencies and disasters do not respect national borders and never occur at convenient times. The intensity of human suffering caused by these events are huge, and affect many aspects of peopleÃ¢â¬â¢s lives such as

Importance of the Tutor in Electra When delving into a novel, drama or other character-based text, analysts often focus their search around the supposed "major characters" who seem to most directly affect the work. In considering Electra, however, just as valuable as Orestes, Clytemnestra or Electra herself is a somewhat minor character, the Tutor. This attendant of Orestes emerges only three times and is on stage for less than twenty percent of the spoken lines, yet his role in driving the plot is as great as any. If Aristotle, one of the true masters of ancient thought, is correct in saying "The Plot, then, is the first principle, and, as it were, the soul of a tragedy," then the Tutor can truly be considered one of the most significant characters in the entire drama. Ã Ã Ã The relationship between the Tutor and Aristotle's conception of tragedy can be carried further, for in his Poetics Aristotle claims, "Tragedy is an imitation of an action that is complete and whole...A whole that has a beginning, a middle, and an end." If this is believed, the Tutor's appearances become an even better match for the tragic form. His three presentations on stage are quite auspicious numerically, and geometrically they form a nearly perfect spread from beginning to middle to end. With each of these appearances the Tutor sets in motion some critical aspect of the plot, thus making himself an agent of another of Aristotle's notions: "But most important of all is the structure of the incidents. For Tragedy is an imitation, not of men, but of an action and of life, and life consists in action." The Tutor truly drives the action of this play, functioning as a glue to hold the plot together and as a catalyst to keep it moving forward. Ã Ã Ã ... ...alls him "the only one I found / Remaining loyal at our father's murder"(1351-1352). Such an idea brings the true depth of the Tutor into the open: he is perhaps the most steadfast character in the entire drama, the one who committed himself to Orestes' cause not out of familial obligation but simply out of loyalty. The Tutor sets this play in motion, propels it in the middle and then continues it towards its end. Such a purposeful nature contrasts greatly with Electra's, and without the Tutor's influence this may have simply been a fifteen hundred line saga of her personal woes. Though traditional analysis makes the Tutor's role seem secondary, it is deceptively important, yet another deception that is quite appropriate for such an individual. Works Cited: Euripides.

My desire to pursue a career in health care is greatly influenced by its unlimited opportunities for career development and the desire to impact another personÃ¢â¬â¢s life positively. As a kid, I always had a burning desire to become a nurse or a medical doctor but my parentsÃ¢â¬â¢ influence and their perception of the engineering profession while in Nigeria lured me away. I trained and practiced as a Materials Engineer back in Nigeria, where I worked as a research and development officer for five years. However, coming to the United States created the turning point in my life. I searched for engineering jobs unsuccessfully for many months, and none was forthcoming despite availability of many job openings in nursing and healthcare related fields. In order to confirm my readiness to pursue nursing as a career, I entered a Practical Nursing program at the Wilbur Wright College in Chicago. At this time, I was still driving cab to support myself, while I dropped it completely upon graduation and passing LPN board examination. A couple of years after becoming a LPN, I applied to DePaul UniversityÃ¢â¬â¢s Master entry program to further my education, and thereby became a full-fledged RN. My dogged persistence paid off. In one way it deterred me from getting stuck to cab driving, despite a very good tax free Ã¢â¬â income. On the other, it allows me to envision my future as a great nurse. My insatiable appetite for knowledge coupled with compassion and commitment to nursing shape my desire to pursue a DNP in nurse anesthesia. Clinical rotations in OR as a close observer during an open Heart Surgery at the IMMC, while a student at the DePaul University also afforded me opportunity to see administration anesthetic drugs by a CRNA. In concretizing my interest to purse a DNP in Nurse Anesthesia, nothing can be more absolute than witnessing the births of our three children and the joy that they have brought in to my life. I saw firsthand as the nurse anesthetist administered the epidural anesthesia to assuage my wifeÃ¢â¬â¢s labor pains. I am interested in becoming a nurse anesthetist because of the fervor that I have for it as a profession, the potential that I posses and the life experiences that have made me the person that I am today. These experiences have strengthened my resolve not only to do the utmost that I can by practicing the profession of nursing but also to help in improving the delivery of quality nursing care and overall image of nursing in general. The values and goals presented in the School Mission are a perfect fit for my ultimate career goals. The entirety of my life has been a challenge and the fact that I am applying to a great school such as the NorthShore School of Nurse Anesthesia is a further proof beyond doubt that coming from the humble roots that I was born in to, I can only be on the path to great success at this juncture. I have been engaged in nursing care of critically ill patients for 7years and I have consistently received outstanding evaluations these past years. With strong backgrounds in sciences, mathematics, computers coupled with good communication and interpersonal skills gained from work experience and college involvement, I believe I have all it takes to be successful in this profession. I have also learnt that patience, perceptiveness, honesty, trustworthiness and ability to work as a team member are essential in fostering effective working relationship. I work well as a team-member as well as independently on my own initiatives, using good judgment and overlook personal preferences where the good of all is concerned. At the present time, I am a member of the American Association of Critical-Care Nurses (AACN) and I also participate in various continue education activities that seek to increase my knowledge and overall clinical skills. My short-term professional goals include passing successfully certification examination for Adult Critical care, also known as the CCRN certification by October this year. I hope to set enough fund aside to augment my tuition for the School of Nurse Anesthesia. I also plan to attend a Medical Spanish class, in order to hone my Spanish language proficiency. It is also in my plan to work part time upon the start of the program in order to keep my clinical skills up-to-date. My long term goal is to successfully graduate from the NorthShore School of Nurse Anesthesia and pass the Nurse Anesthesia Board Examination. After passing the exam, I hope to join the American Association of Nurse Anesthetists (AANA) and other relevant professional associations for networking opportunities, mentoring and support systems. All the goals enumerated above are designed to help crystallize my future plans. I intend to be a successful nurse anesthetist and a well rounded professional. There is too much at stake to fail and to whom much is given, much is expected. I intend to be a shining example to my children and to my community. My DNP project would focus on the effect of anesthetic agents on the intra-operative respiratory Care of obese and COPD patients. Besides finding this profession endlessly interesting and rewarding, I cherish the opportunity to make a positive difference in myÃ patientsÃ¢â¬â¢ day-to-day lives. My experience has a nurse has taught me that helping someone attain their utmost in good health transcends the patientsÃ¢â¬â¢ ethnic background or what social class they belong to. It is amazing how irrelevant the sex or race of an individual is when they come in to the emergency room with a broken arm or had been in a vehicle accident. I am thrilled at the possibilities of learning and practicing that lay ahead of me as a professional in one of the greatest and most noble profession known to man. I intend to take up the challenge and use my expertise to help as many people as possible irrespective of their age, class, race or religious belief. I look forward to the opportunity to start t he Nurse AnesthetistÃ¢â¬â¢s program at the NorthShore School of Nurse Anesthesia, and I accept the challenge, knowing fully well that it is a nail that would help in holding my future together.

Explain the problems of religious language. (30) Some words used within religious language may be viewed as contradictory to our inherent beliefs and logical view as human beings one example of this would be the story of the Ã¢â¬Ëvirgin MaryÃ¢â¬â¢ as there is no logical explanation to how she gave birth. Many of the words used in religious language are also metaphysical and have no physical representation therefore it is very hard for us as humans to fully comprehend the ideas they are expressing. An example of this is Ã¢â¬ËGod is timelessÃ¢â¬â¢ as we as humans live in a world where time is very much present so humansÃ¢â¬â¢ attempting to understand the phrase causes problems as it is outside of our past experiences. Many of the metaphysical questions within religious language can be problematic as it can not be answered through science or our logic for example Ã¢â¬Ëwhy were we created? Ã¢â¬â¢ or Ã¢â¬Ëhow did we get here? Ã¢â¬â¢. Some scholars argue that our human language is not enough to describe religion thus we are doing God an injustice by attempting to explain it in human language, and that we should not expect that applying worldly language to religion to be adequate for our understanding of it. Similarly some argue that we should not even attempt to understand language hence why synagogues have no pictures of God. It may be argued that by giving God human-esk characteristics we are athromorphising god. Another key factor to religious language causing problems is that it is very difficult to interpret whether something should be taken literally or non-literally one example of this is God turning water into wine some interpreters may view it in its literal form whilst others may state that he turned a simple resource into something much more complex. Even if somebodies interpretation is completely correct there is still no real way of proving this. Something else which also causes confusion within religious language is the same words having different contexts for example Ã¢â¬ËspiritÃ¢â¬â¢ one context is alcohol the other is God (the holy SPIRIT) these are to very different things and would cause great confusion if interpreted incorrectly. Another inherent problem of religious language is the argument that Russell put forward when he stated we should not believe a statement which has no evidence to back itself up with and religious texts offer very little of this evidence. Ayer also stated that Ã¢â¬Ëif it is not analytical and cannot be tested, then best to call it cognitively meaningfulnessÃ¢â¬â¢ this ideology would be problematic for religious believers as religion cannot be tested.
