Biomedical Engineering

Biomedical engineering is the study of medical systems and the products used to treat patients. This is used in hospitals and labs by bioreactors. Scientists use this type of engineering to develop fake skin cells for people who have been in a fire, had a deep cut, or a amputation. To maximize the chance of a safe, clean, and bacteria-free cut. Scientists have made a pair of socks that control and monitor diabetic feet and prevent amputations for the patient. It helps cleanse the wound and alcohol is placed in the sock. Fake human tissue is made in labs and some people have it to cover up burns or deep wounds. This fake tissue is 3D printed and it replicates someone's cells and produces them. This replaces stem cells in the body and also helps the body heal faster and more properly. Patients who have had a side of their body burned have to stay in the hospital for up to six months sometimes even longer depends on the degree of the burn. he fake skin was made for people to help them heal faster and it has saved people from getting amputations. This synthetic skins breaths, operates blood flow and heals just like normal skin. They are made out of salt water and organic fibers, some prosthetics even have this synthetic skin on them to blend in with someone like it's their real arm. This skin helps in research as well, scientists inject diseases into it to see the reactions to tell if it's safe for humans. It can replace tumor cells once its out, the skin can be placed in the spot to help heal. Regulating protein count and fibers in the body and seeks signs of cancer. Artificial organs are being made in labs to help people who will die without a transplant and who doesn't have time to wait on doctors to find a doner. Organs-on-a-chip are used to test drugs and help researchers understand how the organ works. The tubes have a vacuum chamber which goes inside the organ and stretches the membrane and expands which can collect up to 50,000 cells. These organs are man-made and people who need transplants can go with the artificial organs instead of waiting for the plane to get there. It's used to pump blood through the body to keep all the cells alive, it decreases the impeller axis shift to help blood flow to the brain. If the organs takes too long, it can lead to infections then it will most likely spread throughout the body to other organs. The other organs would need a transplant as well unless the proper treatment is available at the time. Prosthetics are being made more efficient than ever. Biomedical engineers have made many life enhancing technologies for people who don't have their limbs anymore. There are more prosthetics a than arms and legs, there are fingers, racing blade leg, and even eyes. Approximately 1,000,000 people are deaf in the United States. There are now ears made out of the fake tissue cells and natural rubber that matches the patient's skin tone. They look just like a real ear and it has a hearing aid in the center of it to help the patient hear. It helps as a appearance and aesthetics just like a fake eye, it's hard to tell that the ear is fake. Implants are available as well, the prosthetic is made from a silicone mold of the patient's ear to fit them just right. A very small amount of spirit gum is applied at the base and the middle of the ear to get it to stay attached to the patients face. Farmers use pesticides to keep bugs and animals away that might eat their crops. If an animal eats a part of the crops then the farmer just lost that profit. Farmers want to do everything they can to keep their crops from bugs. Some pesticides are illegal in the U.S, they are toxic and sometimes they can release toxic fumes into the air that we breathe. Pesticides do more than harm pests, they can be dangerous for the human who consumes them. The symptoms of pesticides are nausea, vomiting, stomach cramps, headaches, dizziness, and even death if the poison is in your bloodstream for too long. They also damage the richness of the soil, so by farmers using pesticides on their crops they are hurting their sales in the long run. The soil will lose its nutrients from the poisoning and then water erosion happens which washes away the soil particles making it just plain dirt. Adding more soil to the dirt will not help out the nutrients, it can't compensate for the loss of nutrients in the topsoil. Farmers using GMOs to help their farm animals grow larger so they can sell more product is not illegal. Many farmers use them and GMOs allow them to place unnatural chemicals that make the food taste better so consumers will buy more of their product. Farmers are altering genetic material to produce artificial organisms. GMOs can be used in plants just like animals, in plants it helps them grow faster to produce more to sell. It helps the food the plants make taste better by altering its DNA. The DNA is extracted from sweet alyssum which plant grows the fastest. Scientist take that trait and create GMOs for their plants so they can grow faster. GMOs aren't dangerous to humans unless there are pesticides used on the plants to keep the bugs away. Scientists cross-breed these organisms in labs with bacteria and virus genes. A bonus to genetically altered food is longer shelf life, they are better for the consumer, and it takes less land to grow more food. Biomedical technology helps scientists find cure for diseases like smallpox, rinderpest, polio, yaws, and malaria. Biomedical engineering helps scientists understand how to cure diseases and create a cure for a disease unknown to mankind faster. Biomedical engineers are now closer than ever before to finding a cure for cancer, reporters say it will take about another five to ten years before they actually finish and perfect the cure. They are trying to use heat radiation to kill the cancerous cell through the body without Chemo or an incision. Another widespread disease that affected a lot of people across the world is malaria. Malaria is a plasmodium parasite transmitted by the bit of a mosquito. This disease started from Sub-Saharan countries in Africa, its hot there so the bugs are abundant. Mosquitos traveled from that area to all across the world carrying the disease. The cure was developed by Charles Louis Lavern on November 6, 1880. Back then, there wasn't many cures for disease just medicine to help control it. That was a long time ago and thanks to biomedical engineering, scientists can develop cures much faster and efficient such as someone taken the cure will most likely never get that disease again. Biomedical engineering helps healthcare. It produces more accurate equipment used in hospitals and on animals. Healthcare is so much more advanced now than it used to be, when babies or animals get their shots there didn't used to be any back then. They would just have to go without them and that's why disease was so rapidly growing, because there wasn't many cures but now everything is different. Even simple procedures like getting a cut or a burn required special attention and days of preparation to get better. Now they just give out stitches and anti-bacterial cream to clean it. All of us as a nation have came so far and within time, scientists will discover more and more treatments and cures. There are cures now using antimicrobials to kill microorganisms to stop their growth and to stop the spreading throughout the body. They are injecting good organisms into the body to kill off bad organisms that make someone sick. The earliest type of microorganisms were Penicillin, Salvarsan, and Prontosil and they were one of the biggest scientific advantages of all time. This was a new level of medical care, Pharmacists could only progress and discover more medicines. There are now antimicrobials in hand soaps and Hand Sanitizers which is available on the go. Agents such as bacteria, mildew, and mold that are used to make the organisms in the medicine. The helpful microbes come into contact with the surface and penetrate the cell blocking the harmful microbe to kill off and to limit the cell from growing and spreading from another part of the body. Anti Microorganisms work in the way similar of insecticides and fungicides because of how they disinfect, sanitize, and protect against infections. Peptidoglycan layers act as a spine to a cell and it allows in nutrients to enter the cell like acids and sugars. Vitamins can not enter the cell so the bacteria trapped in the cell must make its own. Cell manipulation is alter genetic human cells

Psychology and Language Essay

Language is a form of communication that allows humans to express emotion, opinions, thoughts, and beliefs. Language is communicated through sounds, gestures, and symbols. It is a developed system for communicating in a society. Languages will vary from one culture to the next and will take on different forms. Languages do not have to be spoken but can be expressed through hand gestures and written symbols. The lexicon is the vocabulary contained within the language. It is the knowledge of the words contained in the language. It is a compilation of all words known, understood, and expressed by the individual. The language is compiled and understood by others contained in the same culture and supports how the language is expressed. Key Features of Language The key features of language are semanticity, arbitrariness, displacement, and productivity. An expression of language occurs when an individual expresses a sound or makes a gesture. The information being sent will be received by the listener or observer. Language is used to gain the attention of another individual through speaking or using hand gestures. Key features of language are the mode of communication that will be used (Hyde, 1998). How a language is expressed is the mode of communication such as speech and hand gestures. The next key feature is broadcasting the message and then rapid fading of the message. The message will fade and then cannot be heard. The next feature is interchangeability. This is the ability to both receive and send the message. Total feedback is occurs when the speaker can hear his own speech and can monitor the language performance as they go and specialization involves producing the speech through the specialized body parts adapted for this role (Hyde, 1998). Semanticity is another key feature of language. It matches the communication with its specific meaning. It involves the primary similarities in all languages. For example all elements on the periodic table are universal but the way the mineral or metal will be expressed by language will differ. In one language water may be expressed as agua but will still have the same meaning in another language even if the word is expressed differently. Arbitrariness is when a sound is emitted with specific direction. The communication or noise it just expressed and no one to interpret the message or no meaning for the expression of the language. If a monkey shrieks while sailing through the trees this is an arbitrary sound. It is a noise that has no destination or it is not focused towards someone else. Displacement is when a speaker expresses a language concerning something that is not present. It expresses things from the past, present or future or things that are physically separated from the communication. For example displacement is when an individual is talking about another country that is far away or a past experience that he recalls into the conversation. Productivity is the ability to express a language or communication that is understandable to others. It is productive to be capable of learning, processing, and emitting a learned language. Traditional transmission is the ability of the human being to learn a language in order to communicate. Humans are born with the necessary physical and mental tools to express a language but that language must first be learned. Children are able to express needs with by communicating by crying but they will need to learn the language to express in words or gestures what they need. Dual of patterning is a feature of language that involves the ability to develop patterns of language and the creation of new forms of the language. Four Levels of Language The four levels of language structure and processing include the sounds emitted or the phonetics and phonology, the meaning, syntax, and utterances. In general phonology is concerned with describing rules used to combine sounds into permissible sequences (Debajuoti, 2000). The sound is produced and then perceived. This is the basics fundaments of language. It is the ability to understand the language and perceive the differences. Changes in the sound that is emitted could change the communication or how the sound is perceived. Different ranges in sound can be applied differently in different languages or cultures. For example yelling in one language could be considered an expression of anger whereas in other languages or cultures it could be an expression of joy. The meaning of the language or the lexicon studies the relationship to the language and the words. It involves the derivation and inflections involved in the language. It represents the multiple meaning behind the words and the ambiguity of the structuring of the language. Syntax involves the forming of sentences within a language. It is how the language is pieced together in proper grammatical sequences. The utterance is when the language is expressed through sounds and in some cases through learned gestures. This expression of the language can involve nonverbal expressions, gestures, and facial expressions. The utterance is the text of the language and how the words are linked together and what is said. Language Processing in Cognitive Psychology The role of language processing in cognitive psychology involves perceiving the information, producing a response, reasoning, judging, conceptualizing, and imagining. A language uses symbols, which are sounds, gestures, or written characters that represent objects, actions, events, and ideas (Debajuoti, 2000). These processes help the individual to plan, apply, and problem solve. Language develops from many cognitive processes such as memory and learning. Language helps to determine how people will think. It is influenced by thought. How we perceive or process information helps to determine the ability to form a language. Human thought processes are closely linked to language and the cognitive process. Language is learned or input into the brain through the cognitive process. Humans commonly use mental representations such as concepts, prototypes, and cognitive schemas. Cultural differences and variations in language can change the perception or how the information in processed. How the information is acquired, stored, processed. The brain contains the human capacity to recognize and learn a language. Human learn through their environment, memory, modeling, and gaining knowledge. Cognition then stores, process, and interprets the information to form a language.

Population And Region of South and East Asia Essay

Population And Region of South and East Asia - Essay Example Nearly every mainland is made up of river valleys, highlands, coastal plains and mountainous regions. The increasing human population in the region has encroached on the tropical forests due to increasing demand for settlement and cultivation land. Although large forest lands still exist, much of the frontier has been taken up by human settlement. The settlement patterns in the region as originally influenced by natural water sources such as freshwater lakes and rivers because they were a source of food as well as a medium of transportation. Environmental factors The people of the region have greatly affected the environmental conditions in the region. Majority of the region is located within the humid tropics with the climate being determined as monsoonal. The region has attracted a number of animals such as the orangutan, the Sumatran rhino, Asian elephant, and Malayan tapir. The region has three major species of tiger namely the Malayan tiger, Sumatran tiger, and the Indochinese t iger. Some unique species of animals are found in this region such as the Komodo dragon which has been regarded as the largest living species of lizards (United Arab Emirates News Agency). Due to the surging population in the region, some of the animals in the region have been described as the endangered species due to their diminishing chances of survival. The people have destroyed the natural habitats of the animals such as the tiger and elephants besides hunting them for their precious skin and other body parts.

Technically, Neil deGrasse Tyson is an astrophysicist, and a science communicator regularly seen as the host of special science occasions. The scientific community has heaped numerous academic and honorary degrees to this 56-year-old Tyson. When we talk about Neil deGrasse Tyson, we are talking about a hardcore scientist and a prime-time badass scientist. Neil deGrasse Tyson was born in October 1958, in Manhattan, New York City, United States of America. His father, Cyril deGrasse Tyson, was a sociologist while his mother, Sunchita Feliciano, was a gerontologist. At the age of nine, Neil visited the Hayden Planetarium, the largest planetarium in the world. After returning from his visit, Neil developed an enhanced passion for astronomy. He attended Bronx High School of Science and actively participated in writing and editing the school’s physical sciences magazine (Marne, 19). Neil possessed not only a great passion for astronomy but he was also an excellent communicator. Surprisingly, he had started giving astronomy lectures at the age of fifteen. In the midst of his teenage lectures, Neil deGrasse Tyson was discovered by the iconic astrophysicist Dr. Carl Sagan. Sagan invited him to join an undergraduate degree program at Cornell University but Neil opted to pursue his degree at Harvard University, where he graduated in 1980 with a Bachelor of Arts in Physics (Marne, 25). After receiving the Bachelor’s degree, Neil deGrasse Tyson became distracted by extracurricular activities like wrestling and dancing. Three years later, Neil proceeded to earn the Master of Arts in Astronomy and Master of Philosophy in Astrophysics from the University of Texas and Colombia University respectively and finally received a PhD of Astrophysics in 1991. Technically, Neil deGrasse Tyson completed his academic journey in 1991, and commenced his career in science. In 1992, Neil

Using Wiki spaces opened another broader era of knowledge for our minds through the course of computer sciences. We prepared lesson plans by including the application, which was extremely content specific and collaborative in every aspect. This lesson plan was made at the end of many sessions and classes and it served the purpose of depicting our understanding of the content that we were taught in the class.

Leaking waste containers ( ethics ) Essay Example | Topics and Well Written Essays - 1000 words

Leaking waste containers ( ethics ) - Essay Example As a result the methods adopted by Tom Treehorn, could very well result in problems for the ABC Company. Environmental agencies are very much particular about the methods, which are adopted by the companies in disposal of the chemical wastes and they take tough action against erring companies. Hence Scott should warn Tom that if he does not follow the company ethics and rules of waste disposal, the matter could be brought to the notice of his superiors, since it could adversely affect the interests of ABC Company. 2. Should Scott inform Tom that he will not interfere with Tom’s plan? But he will not help him with it either. Answer: Scott very well knows that Tom is really not serious about preventing environmental problems that will be caused by ABC, if chemical wastes are not disposed properly and is only looking at ways by his workload is lessened and also finding ways to profit him. Scott being the Engineer of ABC and being given the responsibility of inspecting the warehou se, should never agree to Tom’s plan because it will affect his company. Being an employee to the ABC Company he would be taking the wrong decision by allowing Tom to dispose the chemical waste, by adopting his own time tested ways, which are very much against the rules, set by the Environmental Protection Agency. Thus Scot should never tell Tom that, he will not interfere with his way of disposing the chemical waste nor should he be given the assurance that Scott will not interfere in such matters. 3. Should Scot advise Tom not to go ahead with his plan? But not interfere if Tom insists on going ahead anyway? Answer: Scott being the Engineer of the ABC Company has got the authority to tell Tom regarding the best methods, which are to be adopted by companies in dealing with the disposal of the chemical wastes. Since it is a very serious matter that can undermine the ABC Company’s interest, future and also at the same time result in severe forms of penalties from the En vironmental Protection Agency and closure of the company operations, he should really advise Tom not to go ahead with his plan for the chemical waste disposal. Even after all this advise being given by Scott to Tom to follow the company norms, Tom still insists in going ahead with his plans of the chemical waste disposal, then Scott has to interfere and inform Tom’s superior and also the top management of the ABC company, since this could in the future become a serious issue for ABC. 4. Should Scott say nothing and help Tom with his plan? And why? Answer: If Scot says nothing to Tom’s stated plans for the chemical waste disposal of the ABC Company and allows him to go forward as per his own plan, then it will show that Scott is not a good employee of ABC. Scott being the Engineer is being entrusted with the duty of the warehouse inspection and to find out defects that are existing within it and take corrective actions to rectify the faults. If he decides to agree to To m’s plans, then he will be endangering not only his employment as Engineer within ABC but also the whole company’s future, since if the Environmental Protection Agency comes to know the illegal methods of chemical waste disposal adopted by Tom, then they could take severe action against the ABC Company. Hence Scott should not help Tom in going ahead with his plans but has to strictly warn Tom regarding the future adverse impacts, which his

Article Review (human resource management) Example | Topics and Well Written Essays - 500 words

Review (human resource management) - Article Example e, the best performing companies are in a league of organizations that have shifted their focus from development and expansion of facilities to personal development. These include McDonald’s, General Electric, American Express, among others. In a survey carried out by Chief Executive Magazine involving more than 300 global firms, almost all respondents ranked identifying and finding the right leaders as the biggest challenge, with prospects of demand for leadership increasing to the future (Maxwell, 2006). This implies that companies in addition to experiencing challenges in creating a pipeline of leaders within their operations have also to develop new skills and capabilities in accordance with business transformations, investing in leading technologies, and globalizing their operations, in addition to entering into new challenging partnerships. Sam Palmisano, President and CEO of IBM explained that the biggest challenge for companies in embracing globalization, and the main aspect that drives businesses in the current sophisticated market is and has been obtaining and retaining a supply of â€Å"high value skills† (Palmisano, 2006). This explains the strategic decisions by leading companies such as MacDonald’s to review development of the leading 200 managers in ensuring their talents are in tandem with the current market dynamics, and finding ways of imparting more skills to make them more competitive; this puts them in line with the current management demands in a highly dynamic global market. On the other hand, maintaining a high degree of strategic, cultural, and internal fit within an organization ensures such an organization has a perfect system of practices; an organization must not only focus on talent management, but has also to take interests in â€Å"organization learning and knowledge management† (Evans, Pucik & Barsoux, 2002). Therefore, companies will always attain a competitive advantage not only in designing best pr actices, but because
