Biomedicine pre study - Essay Example The remaining portion of the cell except the nucleus or the knuckled region is the cytoplasm and consists of cytosol and various organelles essential for the functioning of the cell. Ribosomes are simple organelles in which protein synthesis occurs (Kent, 2000). The cell wall of plant cell is made up of cellulose while that of animal cell is made up of phospholipids. Such a cell wall allows the plant to take in large amounts of water through osmosis without being destroyed. Plant cells synthesise energy by means of photosynthesis during which sunlight is converted to energy. For this purpose, plant cells have chloroplasts which have their own DNA and which direct the work of chloroplasts, These organelles are absent in animal cells and animal cells synthesise energy through metabolism of the food they take. Another major difference is the presence single large vacuole in the plant cells. Animal cells have small multiple vacuoles. Also, plant cells have a regular shape and the shape of animal cells varies greatly (Kent, 2000). DNA and RNA are the structures in the cell which carry inherited traits. Inheritance mainly occurs due to meiosis. In this type of cell division, the genome of the diploid germ cell which has long segments of DNA organized in chromosomes undergoes two rounds of cell division resulting in four haploid cells. During division, replication of DNA occurs. Each of the four haploid cells contains one complete set of chromosomes which is half of the genetic content of the original cell. The haploid cells act as gametes and fuse with gametes of the partner. One gamete fuses with only one gamete of the partner . This is known as fertilization and this leads to a new diploid cell or zygote. Thus chromosomes of each parent undergo recombination in a homologous manner during the process of meiosis and thus each zygote inherits DNA from both parents (Kent, 2000). The four most

Consumer Math Essay Example | Topics and Well Written Essays - 250 words

Consumer Math - Essay Example The value of the annuity after five years will be the sum of all the deposits plus the interest earned over a period of five years. Another example where an annuity can be applied in one’s personal finances is when one plans for one’s retirement fund. An individual may decide to put in $2,000 at the end of each year for the next 20 years into an IRA. If the IRA promises a return of 12 percent per year compounded annually, the individual will get a certain amount from the IRA after 20 years. In making investments, annuities are very relevant. Several options are presented to individuals who want to make an investment. One such example is deciding whether to make a lump sum deposit or a periodic deposit for several years. If the interest rates are equal and the maturity date is the same, one has to decide which alternative will be more profitable. The examples presented above are just some applications of consumer math, specifically annuities. Indeed, it is essential for every individual to understand the concepts covered by consumer math because it has a huge impact on one’s personal finances. Chatham Central Schools. (n.d.).

Systems and Cultural Investigation Essay Example | Topics and Well Written Essays - 1250 words

Systems and Cultural Investigation - Essay Example This paper seeks to analyze the cultural systems that exist in healthcare organizations The term system is a set of interrelated, interacting or interdependent elements that may be used to work together in a certain work environment to perform a particular task that is required by the systems aim. Systems can be improved all the time but before it is improved one must consider knowing how its products are created, the reasons why they are created and how they can be improved. Many systems work under some set of principles so as to help us understand how they behave, for example, the whole system may have one or more of the defining functions. Each part of the system can affect the characters and behaviors of the whole system. Also, it is equally important to note that behaviors and properties of just one part of the system can be very dependent on the behavior of the other parts of the system. Each part of the system may necessarily but may be insufficient to operate alone so as to carry out fully the defining role of the whole system. Healthcare system is often very cumbersome and opaque to their users including patients, nurses, and even the physicians. It best described as complex adaptive systems because they are collections of the individuals who are very free to act in various ways that are unpredictable. The boundaries of the organization can be very fuzzy since membership changes and providers of the services can simultaneously be members of other sub-systems. Given the complexity of these sub-systems, the action of the individual teams are much interconnected so that the action of one sub-system can change the whole context of the other sub-systems. Microsystem may change over time so that it can respond to the needs of their patients, staff members and the external pressure from the surrounding environment. They try to coexist properly with other

On being the youngest Essay Example for Free

On being the youngest Essay I hate being the baby! Thats a common statement one hears all too often. Im the youngest one in my family,and the only girl among two brothers at that. Quite a number of my friends are the eldest among their siblings, and from what Ive heard from them, their little sisters and brothers are probably just a few years away from the friendly neighbourhood psychiatrist. What with all the abuse, its a miracle how they avoid becoming physically and emotionally retarded. ( sorry guys, I just had to stand up for those poor kids! ). However, I firmly believe that every cloud has a silver lining, even if its not always visible. Being the youngest, we do gain a few vital skills to survive in this dog eat dog world. In the process of getting pinched, slapped, punched, and kicked around by our older siblings, we develop a strong retaliation mindset that keeps us from being obliterated by our demented siblings. You decapitated my Tropical Swimsuit Barbie ? Look, your Hot Wheels were so hot, they melted! Undoubtedly, my brothers have suffered the wrath of my active self-defence mechanism more than once. Even if I fail to get back at them physically (Im just a gentle, innocent girl, okay? ), I generally make sure they pay by spiriting away their beloved possessions. Its amazing how many nooks and crannies one can find in a standard double- storeyed house. Sure, its mean, petty, spiteful and selfish, but hey, who ever said anything about being an angel? Once, I remember grabbing hold of a handful of my brothers beloved computer games and throwing them over the gate onto the path of an incoming car. I got a pretty good hiding for it, but ahhh, the satisfying sound of cds cracking under pressure out-weighed the punishment by about a hundred times. As the youngest, we are the worker ants around the house. That is, when our parents are not in. As a result, we acquire very important characteristics such as being responsible, efficient, hardworking, etc. Theres this really misguided notion that the queen bees are always the responsible ones. All they do is to order us around, belting out commands like a drill sergeant. Being the only girl in the household during my mums absence, I get ample preparation for a future married life (or as one would think, a future career as a house-maid ). Being the youngest too means that my brothers become deaf to any kind- hearted suggestions I have to increase their work efficiency. (eg. Why dont you just get your lazy butt off the floor? ) With all the practice we get, most of us have the persuading skills of a politician. I find this especially useful when Im short of pocket money. After a few minutes of manja-ing, my purse would be filled to the brim again! (Like magic! ) I guess this is a privilege available only to us. Somehow, older siblings who act manja are not generally accepted by society. Those who have the audacity to do so are usually met with the curt dont-pretend-to-be-cute reply. Still, not everything we gain by being the youngest is good. Havent you noticed? The youngest one is almost always the fattest. Sadly, Im a living testament to this. While both my brothers are lean, slim and thin, Ive always been kind of chubby my whole life. The last cookie left? Let your sis have it lar. The last piece of pizza? Give your sis All this food stuffing has left its mark on me physically. (Sigh) Well, I guess you just cant have your cake and eat it too literally. All in all, I think life was intended to be a bed of roses for us young ones. Unfortunately though, a few durian husks got in the mix. However, at the end of the day, what really matters is having a family that loves you and cares for you, regardless of whether youre the eldest, the youngest, the in betweens, or even the only child.

The Journey To Becoming A Nurse Nursing Essay

The Journey To Becoming A Nurse Nursing Essay My intellectual interests, academic and, professional objectives encouraged me to pick my field of study in healthcare, to be specific, the profession of nursing. During adolescence, children are encouraged to consider various majors and future career options. Some mature fast and realize their goals during early adolescence, some realize it mid-adolescence and, others late. I was uncertain about my career path during my early stages. However, my passion for the medical field was and still is firm. I come from a family made up physicians, pharmacists, nurses, laboratory technicians, and physician assistants; this, of course, influenced my familiarity with science majors.   With such an interest in mind, I began volunteering in hospitals at a young age, where I was surrounded by patients who approached me for assistance. I was able to assist the patients to the doctors office and always tried to have a conversation with the patient. In such an occurrence, I embraced the feeling of n eed and comfort from those whom I have helped. One notable experience that I have had was caring for my grandmother, who was difficult to cope with due to her massive mood swings and impatience. I knew she trusted and depended on me as she clutched my hands for guidance. At that time I knew I want to definitely take part in medical field. Therefore, I decided to take up field in health care profession after undergraduate studies. Passion, determination, and patience are important key terms to succeed in a health care profession: these characteristics work to my advantage. During my academic life, I continued exploring majors that would fit my goal. After much discussion with my college advisors, I came across Letters, Arts and Sciences at Abington College. As I researched further into the degree, I was sure I wanted to do LASAB. This is my chance to challenge myself by creating my own major that will help me fulfill my requirements for post- graduate studies, in nursing career. This academic helped me to find the way to the right career path that will introduce me to the healthcare world where it ______ me to earn a masters degree after finishing my bachelors. Over the course of my undergraduate studies, I have taken many courses that have helped me grasp the phenomena of science and patient care. College opened a new chapter in my life, a chapter filled with science. I comprehend with the facts and theories of the human body and admire the discoveries of new cause of illness and treatments which becomes a great advantage to the world as a whole. College life has made a great input in my life by helping me enter adulthood and gradually learning to cope with stress, manage time, and make responsible decisions for myself. The four core areas of the Letters, Arts, and Sciences major are Research Methods/ Projects Critical Analysis Communication Skills Theory/ Application Skills The courses that I have chosen to apply to these core requirements will fulfill the requirement for this degree and will benefit me in my planner Nursing career. The skills I gained from these courses are fundamental to becoming successful in a health care profession. Research is a process of study or examination of a subject from different points of view.  I have selected Microbiology 107; Elementary Microbiology Laboratory, and Chemistry 111 and 113; Experimental Chemistry to the Research Methods/ Projects to fulfill the core requirement. Microbiology 107: Elementary Microbiology Laboratory gave me an introduction about microbes. I learned the importance and the proper handling of microorganisms through demonstrations and working on each experiment. The lab has also helped me to identify and count bacteria, effects of chemical and physical agents on microorganisms. This course has helped me learn the importance of controlling microbial growth on peoples bodies and how failure to do so can lead to the spread of disease, especially in the hospital setting. Chemistry 111 and 113: Experimental Chemistry introduced me to chemicals and challenging experiments. It helped me better understand how to interpret data about various experiments that dealt with introductory chemistry. I learned to write a formal laboratory report, interpretation of data using statistics, and an appreciation for what instruments can do. Each of these courses will help me focus on areas that are relevant in the medical field. International Studies 100 fulfills to the Critical Analysis core requirement.  I believe it is important to be able to understand people and their background/culture, especially when working in the health-care profession. There is a great chance of meeting people from different diversity in my field. As a health care professional, I must learn and know about patients cultures while I treat them. This course has given me a basic understanding of the many cultures and their global issues, such as financial crisis, racism, health issues, and human rights issues. This course helped me to connect with different cultures, their domestic issues, and responses to human rights violations. In a hospital setting, health care professionals are faced with patients that have many different issues and one main issue would be race. Health-care professionals must understand that all come from different culture with different issues; therefore, we should not be judged by the race because we are all humans. We must treat people equally. We will be able to connect to patients better and help them deal with their illnesses better if we are knowledgeable about their culture. The course will help me to understand everyone better.   I apply INART001, Integrative Arts into the core requirement of communications skills. This course helped me to develop critical perception, knowledge, and judgments through examining the basic arts through communication. Communication is very important and this course helped me to communicate in both art and non- art situations. When one thinks of the health care, a complex array of professions come into mind. In order for all these professions to provide the best possible care for their patients, communication between them is vital. For example, suppose a patient has a penicillin allergy and the doctor ordered a medication that is a penicillin derivative. In that case, the pharmacist calls the doctor and a new medication is prescribed. This course helped me communicate in simple way that others will understand and gave me more confident. During my internship at the hospital, I noticed that communication is very important and presenting a simple communication will help the patie nt understand the nurse better. On the other side, Integrative arts such as art, music, dance or drama introduced as Art therapy in health care. This therapy was used to help child survivors of Hurricane Katrina overcome mental traumas and people with schizophrenia BBC news.   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  I place Anthropology 45, Cultural anthropology to the core requirement of Theory/Application skills. As I mentioned earlier, it is important to be able to understand people when working in the health-care profession. All societies have rules, standards, conventions and beliefs. Studying anthropology allowed me to understand how social culture work. As a health care professional, it is important to understand the society, government, religion and their culture. This course focused on human culture; I learned to appreciate cultural diversity. An in-depth knowledge into the human culture is especially important in todays health care, especially in a diverse country like the United States. Take, for example, the culture of Jehovahs Witnesses. This denomination prohibits blood transfusions for their believers. Respecting their wishes, hospitals now have bloodless surgeries where newer techniques have been developed that do not require blood transfusions, even for m ajor invasive surgeries like coronary artery bypass graft. Also in this day, a healthcare provider sees patients from various countries and various cultures. Something considered elementary in a culture might be considered taboo in another. For example, in the American society women have the same rights as men and considered capable to make their own decisions, as where in some cultures, its the man who makes the decisions in the family. In cases like this a healthcare provider must respect the differences and work with their patient to provide what is the best possible care for their female patients. Therefore, I must understand the rules and beliefs of other cultures so I can understand the patients better.   Everyday people face many different types of problems. It could be physical, emotional or mental stress. As a health care professional, it is important to understand the reasons for those problems and assisting the exact treatment Psychology is the science that enables me to connect to an individual through the mind to understand and deal with the mental processes and behavior of individual human beings. I have chosen five 400 level courses from three areas that relate to my theme. Those are Kinesiology 445: Alcohol and Drug Education, Psychology 470: Abnormal Psychology, Psychology 424: Applied Social psychology, Counselor Education 401: Foundations of Chemical Dependency Counseling, and Biology 495. Kinesiology 445: Alcohol and Drug Education helped me to understand and learn more about many types of drugs and alcohol uses not only in the American society but worldwide. Moreover, it has taught the drug physiology, drug-related health effects and issues related to social and psychological effects of drug use and abuse. Alcohol and Drug can affect peoples lives so fast. I did a research paper about Alcohol and drug, as part of the research I surveyed twenty neighbors and 80% of them addicted to alcohol and drugs. Most of them were addicted due to stress but some of them started out as a fun hobby. Many people find Alcohol and Drug as a solution to their problems. Therefore, I will definitely come across many patients that are addicted to alcohol and drugs. I am sure I am able to use the fundamental information from this course and apply it to the patients I might come across in my professional field. Another challenging course was Psychology 470: Abnormal Psychology has taught me the understanding of types of abnormal experience and behavior personality, as well as mental and psychotic disorders that impact multiple areas of a human life that might not be able to be diagnosed on a personal basis.  The most common disorders are Schizophrenia, Bipolar Disorder, Eating disorder, Autistic Disorder, Borderline personality disorder and Obsessive-Compulsive Disorder. This course is mostly focused on the identification, treatment and understanding of abnormal behavior and psychopathology. It taught me the different diagnoses of types of behaviors, and it will definitely help me in my health profession, especially if I decided work on psychiatric department. Psychology 424: Applied Social psychology, gave me an overview of social psychological theories and research methods to field settings and to the study of social issues. It taught me how to conduct a survey and analyze a report based on a study. It has also helped me to understand the social life and how psychology applied to social life every day. Especially in health care settings, I must apply social psychology to understand social and practical problems thats happening around us. I must be motivated , making sense of my co-workers, social perceptions, and understanding the bias order for me to perform a satisfaction job that will draws a general impression for my characteristic such as intelligence. Counselor Education 401: Foundations of Chemical Dependency Counseling introduced me to the concept related to drug and alcohol dependency, diagnosis and assessment, its prevention, counseling and treatment of dependencies. It has helped me to understand how to deal with that are addicted to various types of drugs like cocaine, heroin, and methamphetamines. A person becomes chemically dependent due to several factors such as environment, psychological, or genetic. Health care provide residential, outpatient, extended, and aftercare treatments for someone who is chemically dependent. On the other side, Twelve-Step meetings are available for those who interested in self-help recovery. I was assigned to attend a Twelve-Step meeting for Alcoholics Anonymous(AA). The stores that I heard during the meetings were depressing because they were so addicted to alcohol and regret their past. This meeting is part of the treatment to be sober. Chemical dependency is chronic and can be fatal. Somet imes, chemical dependency affects health care professionals and co-workers are aware of the signs and symptoms. I have selected Nutrition 251, Sociology 035, and Biology 110 to full fill the humanities and the social science area. Nutrition 251, Introductory Principles of Nutrition, is a course that gave me more knowledge on principles of nutrition. This course broadens my knowledge about the physiological functions and food sources that related to human growth. It helped me to focus on my nutrition better and stay healthier. Especially in healthcare, it is important to make sure the patient is getting the right amount of nutrition. If the patients nutrition is imbalanced, it can cause diarrhea and risk of infection. Therefore all the knowledge that I learned from this class about nutrition will help me to provide a better nutrition life style to my patients. Sociology 035, is the study of aging in older people. The common beliefs, aspects of aging, how economy and family influence the aging process. The course helped me to be more kind, warm and practical with people .A nurse must be kind, sympathetic and compassionate because when I work with patients it will give me better knowledge on how to deal with everyone. I have compared facts that I learned from this class with my parents and grandparents behavior, which helped me understand them better. For example, as my grandparent get old, the chances of them listening to their kids are rare. Even if they are right or wrong , they want the kids to accept it. Once the kids get married and leave the house, the parents starting a new life where they are bonding more to each other. Thats something I have noticed in my grandparents life. All the knowledge that I acquired from this course will help me understand older peoples relation to others and how they would accept the world to live their li fe. Biology 110, Basic Concepts and Biodiversity, taught me the foundation of the basic concept of evolution. It gave me an understanding of living organisms, how genetic processes provide continuity between generations and how evolutionary processes take place. This course includes both lecture and lab. It is the study of living organisms; all life depends on certain physiological and chemical functions. To work in healthcare you must have a basic understanding of the underlying principles of life. These courses that I have listed above are important in my future education that I plan on focusing on after graduation. In health care, it is critical that students understand any individuals different characteristics and behaviors before I respond to patients symptoms. As a capstone course: BIOL 495, I have an internship, at Temples Jeanes Hospital in North East Philadelphia a. As an intern at the hospital, I have been assigned to the same day surgery unit department with patients. This opportunity will also allow me to work with professional staff and patients. It is my duty to go to each patient to check on them to make sure they are doing great because they are recovering from the surgery. Sometimes they would ask juice/water and some of them might need to use the rest room so it is my responsibility to take care of them. Meanwhile, I go with the nurses to each patients room when they go over the surgery procedures and learn how pre admission is done on a patient. I will be attending to the needs of patients that are undergoing different procedures and an opportunity to interact with surgeons, physician assistants, and nurses. It also will be hands on experience with all the skills and materials that I have learned in the courses that I have lis ted in this proposal   In conclusion, I feel that my education has shaped my life to what is today and these courses listed have gave me a better understanding about medical issues happening in this world. Health care profession is not a relaxing profession but demanding and stressful occupation, yet I am ready to face the various situations I may be in and become stronger and wiser in my profession and as a person. It is also a profession where every day I am guaranteed to touch a life or be touched by the lives of others. Letters, Arts, and Sciences at Abington will help me reach my goals after my undergraduate education is complete.

How does a permanent magnet work? :: essays research papers

Some materials have a feature known as ferromagnetism. The prefix "ferro" refers to Iron, which is one such material. Ferromagnetic materials have the ability to "remember" the magnetic fields they have been subjected to. An atom consists of a number of negatively charged electrons, orbiting around a positively charged nucleus. These electrons also possess a quantity known as spin, which is roughly analogous to a spinning top. The combination of orbital and spin motions is called the angular momentum of the electron. Angular momentum is perhaps most easily understood in the case of the Earth: The earth spins about a central axis, which means it at has an angular momentum around that axis. The planets also have an angular momentum as they revolve about the sun. Now, the angular momentum of an electron is a vector quantity, meaning it has direction. The motion of the electron produces a current, which in turn generates a tiny magnetic field in the direction given by the angular momentum. Thus an atom can behave like a dipole, meaning "two poles". The direction of the orbital and spin angular momentum of the electron determine the direction of the magnetic field for the electron and the entire atom, thus giving it "north" and "south" poles. Different atoms have different arrangements of electrons into their orbits, and thus have different angular momenta and dipolar properties. A ferromagnetic material is composed of many microscopic magnets known as domains. Each domain is a region of the magnet, consisting of numerous atomic dipoles, all pointing in the same direction. A strong magnetic field will align the domains of a ferromagnet, or in other words, magnetize it. Once the magnetic field is removed, the domains will remain aligned, resulting in a permanent magnet. This effect is known as hysteresis. Few materials are actually ferromagnetic; however, all substances have a diamagnetic nature. Diamagnetism means that the molecules within a substance will align themselves to an external magnetic field. The external magnetic field induces currents within the material, which in turn result in an internal magnetic field in the opposite direction. This effect is usually quite small and disappears when the external magnetic field is removed. Some materials are paramagnetic. This is the case when the orbital and spin motions of the electrons in a material do not fully cancel each other, so that the individual atoms act like magnetic dipoles.

Essential Components of Effective Marketing Information System Essay

A marketing information system (MIS) is intended to bring together disparate items of data into a coherent body of information. An MIS is, as will shortly be seen, more than raw data or information suitable for the purposes of decision making. An MIS also provides methods for interpreting the information the MIS provides. Moreover, as Kotler’s1 definition says, an MIS is more than a system of data collection or a set of information technologies: A marketing information system is a continuing and interacting structure of people, equipment and procedures to gather, sort, analyse, evaluate, and distribute pertinent, timely and accurate information for use by marketing decision makers to improve their marketing planning, implementation, and control†. Figure below describes the major components of an MIS, the environmental factors monitored by the system and the types of marketing decision which the MIS seeks to underpin. The marketing information systems and its subsystems The explanation of this model of an MIS begins with a description of each of its four main constituent parts: the internal reporting systems, marketing research system, marketing intelligence system and marketing models. It is suggested that whilst the MIS varies in its degree of sophistication – with many in the industrialised countries being computerised and few in the developing countries being so – a fully fledged MIS should have these components, the methods (and technologies) of collection, storing, retrieving and processing data notwithstanding. Internal reporting systems: All enterprises which have been in operation for any period of time nave a wealth of information. However, this information often remains under-utilised because it is compartmentalised, either in the form of an individual entrepreneur or in the functional departments of larger businesses. That is, information is usually categorised according to its nature so that there are, for example, financial, production, manpower, marketing, stockholding and logistical data. Often the entrepreneur, or various personnel working in the functional departments holding these pieces of data, do not see how it could help decision makers in other functional areas. Similarly, decision makers can fail to appreciate how information from other functional areas might help them and therefore do not request it. The internal records that are of immediate value to marketing decisions are: orders received, stockholdings and sales invoices. These are but a few of the internal records that can be used by marketing managers, but even this small set of records is capable of generating a great deal of information.
