Engineering Is A Dynamic And Diverse Field Of Study

Engineering is a dynamic and diverse field of study that opens many doors to exciting careers throughout the world. The first question students normally ask when considering engineering as a career is what do engineers do? which can be considered an unanswerable question as Engineers perform a multitude of jobs. Perhaps a more appropriate question would be what do engineers learn? which can be answered with much more ease. Engineering students in different departments won t take all the same courses, for example, a chemical engineering student will be taking chemistry courses while an electrical engineering student will be taking electrical courses. However, every discipline overlaps with another, which can be seen on the engineering disciplines tree. In addition, some courses are required to be taken by every engineering student no matter the faculty they re in. There is also an option for engineering students to achieve an additional degree such as a business degree, but this requi res the student to be enrolled in supplementary courses. It is nearly impossible to give an exact job description of a chemical engineer as there is an array of different employment options. Chemical engineering specialises in the conversion of raw materials into consumer products. The chemical engineering program teaches students how to complete tasks that include the design and use chemical reactors. Chemical reactors manipulate a chemical reaction to its maximum efficiency in order toShow MoreRelatedStatement of Purpose996 Words   |  4 Pagesprinciples, methodologies, tools and practices in the field of finance.

Overview of Biomedical Engineering as a Career Path

â€Å"Choose a job you love, and you will never have to work a day in your life.† (Confucius) According to the Whitaker Foundation, biomedical engineering has existed for centuries, perhaps even thousands of years. â€Å"In 1816, modesty prevented French physician Rene Laennec from placing his ear next to a young woman’s bare chest, so he rolled up a newspaper and listened through it, triggering the idea for his invention that led to today’s ubiquitous stethoscope.†(The Whitaker Foundation). â€Å"Biomedical engineering achievements range from early devices, such as crutches, platform shoes, wooden teeth, and the ever-changing cache of instruments in a doctor’s black bag, to more modern marvels, including pacemakers, the heart-lung machine, dialysis†¦show more content†¦According to the Canadian Medical and Biological Engineering Society, biomedical engineers should have the following characteristics: the ability to think analytically and solve problems, the ability to visualize complex processes and equipment, a willingness to improve their knowledge and skills on an ongoing basis, and the ability to work effectively with people from various disciplines and educational backgrounds. Biomedical engineers should have a strong interest in medicine and engineering.(Canadian Medical). They should also have a great amplitude in science and mathematics. (Canadian Medical).

Character Formation Education Instructors -Myassignmenthelp.Com

Question: Discuss About The Character Formation Education Instructors? Answer: Introduction This can be stated that assigning each and every employee with their own personal laptops will really be a good and helpful idea. This will be beneficial both to the employees of all the branches of the company and also the managers. The managers will be able to track the performance and the activities of the employees (Coverdale-Jones, 2017). This will also make the shift timings much more flexible. Even during the off days or on any holidays or if there are any such emergency the managers and the employees can stay in contact with one another. Often there is the need for consulting with the employees of all the different branches together. There can also be the need for some kind of board meetings that requires the presence of all the members. So, it often becomes a problem to assemble all of them together at the same time. So, if the employees are having a laptop of their own they can easily stay in proper contact with each other. They can also talk to the concerned authorities who might be located in some other branch. The hierarchies can also stay in proper contact with the employees through emails and other internet websites as well. This will help in increasing the overall production of the company.

Pedagogy of the Oppressed Chapter 2 Reflection Essay Example

Pedagogy of the Oppressed Chapter 2 Reflection Paper Pedagogy of the Oppressed, falls into the political philosophy genre. After I read Chapter 2 of Pedagogy of the Oppressed, my first thought was about the reservation boarding school system. Indian schooling started with missionaries and teachers in missionary schools were at least as interested in salvation as in education. According to many observers, the discipline of the schools usually included getting Indians to dress, speak, and act like white people. Native Americans serve as perfect â€Å"containers† and â€Å"receptacles† for teachers of that time. (Freire 4) Many teachers that teach in Tribal communities often use the concept of â€Å"the teacher know everything and the students know nothing†. (Freire 8) This semester I had a teacher that said, â€Å"I’m going to teach you as though you know nothing†. This goes to show that teachers, even in current times are obsessed with their authority over students. The â€Å"banking system† only works to the extent of students being able to regurgitate what the teacher tells the student. The students do not learn when they are told to memorize items, just so the student can get a good test grade. I have experienced this during my academic career. I personally retain more information when teachers communicate and tell me why I need to learn what I need to learn. â€Å"’Four times four is sixteen; the capital of Para is Belem. The students records, memorizes, and repeats these phrases without perceiving what four times four really means, or realizing the true significance of â€Å"capital† in the affirmation ‘the capital of Para is Belem,’ that is, what Belem means for Para and what Para means for Brazil. † This type of teaching is taught everywhere. I feel as though it is worse for Tribal communities, and I’m only saying that because the high school drop out rate is higher among Native Americans th an other ethnicities. Not to mention, in the university level, the graduation rate is lower.

This reading was fairly difficult. I am not used to reading such complex writings.

This is the first time I have ever read something of this magnitude, I enjoyed it. I felt as though it challenged me to break out of my comfort zone. Bibliography Freire, Paulo.

The Worlds Largest Gypsum Crystals, Naica, Mexico Essays

The Worlds Largest Gypsum Crystals, Naica, Mexico Essays The Worlds Largest Gypsum Crystals, Naica, Mexico Essay The Worlds Largest Gypsum Crystals, Naica, Mexico Essay Research Paper The Worlds Largest Gypsum Crystals A mile below one of Mexicos most important lead and silver mines, and a few miles above the earths magma lies a magnificent Geological Wonder. It Is Known As â€Å"The Cave Of Crystals. It contains the largest gypsum crystals known in the world to date. The cave was discovered in 2000 by two brothers drilling 1000 feet below the ground while working for Penoles mining company (Garcia-Ruiz et al. ). Man and mining have had a negative impact on the crystals, and should be held accountable for the future fate of this geological wonder. We must prevent its destruction, and benefit from the knowledge that science can gain studding this unique treasure. Cave mineralogy is a fairly new field of study that will continue to grow and earn a prestigious place in the larger scientific community. This find is the most important geological discovery made in our lifetime. This phenomenon merits a description. Growing up from the floor, the enormous crystals mirror columns of light, perfectly transparent and luminous. Among the giants is a prismatic shaped crystal measuring 11 m long. Many perfectly formed shards up to a meter in size sparkle and shimmer across the ceiling and walls. It is a magical place, described as a surreal fantasy world (London, 25). [pic] In Northern Mexico, about 100km, southeast of the city Chihuahua lies the Naica Mine. It has been operated by the Penoles mining company since 1952. They are the largest producers of lead and silver in Mexico, along with the production of zinc. The opening to the mine is on the North side of the Sierra de Naica, which according to scientific data lies above three known faults, the Gibraltar, Naica and the Montana. These faults still control the rise of thermal fluids. Hydrothermal circulation is responsible for the location of mineral deposits. Many years ago, tectonic stressors created cavities inside the aquifer; one of these caves today is called â€Å"The cave of crystals. † It is famous for the gypsum giants (Forti, 135). This discovery holds many secrets that will be exposed by science. The geological process that dictated the unique environment from which these giants materialized consisted of the natural pairing of two diverse fluids filling into the cave. One being from the deep, (phreatic), and the other from the shallow or (epi-phreatic) and vadose levels. These hydrothermal fluids, which are directly connected to the origin of the caves and mines, have been functioning as they are today for over twenty five million years. Over time, with these two chemicals overlapping and mixing with one another, we end up with an overabundance, referred to as â€Å"super-saturation† (Fricker, Garofalo, and Gunther, 620) This formed the perfect nursery required to develop these gorgeous gargantuans. A 2011 Journal printed a paper entitled â€Å"Role of Fluid Inclusion Analysis in Understanding Giagintic Selenite Crystal Growth in a Deep Karst Cave. â€Å"The paper offered a recent study of fluid inclusion has shown that the crystals were formed within a small margin of temperature. The solubility of gypsum and anhydrite are the same at just under 54 °C. These crystals grow at low supersaturation and from low salinity solutions. The analysis data shows that dissolution of anhydrite formed during hydrothermal mineralization produces a growth solution consistent with that of oxygen and sulfur isotopic compositions of gypsum crystals. This study puts forth that the huge crystals were created by a self-feeding system, fueled by a solution-mediated anhydrite-gypsum phase transition (Garcia-Ruiz, 327-330). Man and mining have had a negative impact on these wondrous crystals. Based on the current research and data available concerning the growth of crystals, the oldest Naica mine crystals date back about 400,000 years. This date is not exact. Scientists measure present day rate of growth to determine the precise age of a crystal. Unfortunately, these caves were dewatered by the mining industry in 1985. This lowering of the water table stopped the accretion process. The supersaturated water that fed the crystals was no longer available (Badino et al. 124). Man has put an end to this amazing geological environment that has existed for somewhere around four hundred thousand years. According to the International Journal of Speleology, the temperature inside the cave has drastically decreased. The main part of the mine has been connected to the cave and this creates air circulation. The cave temp drops 0. 6 degrees C. per year. The dew point was met in 2005 and a condensation process started. â€Å"At this location the giant gypsum crystals started to rapidly dissolve and new mineral phases began to precipitate† (Badino, 126). Once again, we have evidence of damage being done by mankind. The International Journal of Speleology states that upon analysis secondary minerals that appeared after the dewatering of the crystals the evolution of new speleothems seems to be due to the fluids contained in the crystals themselves. The Journal states: â€Å"Thus, for the first time, the fundamental role played by evaporationcondensation processes have been applied not only to the shape of speleothems, but also to the control of their mineral composition† (Badino et al. 125). There is much to be learned by the scientific community by studying this unique environment. Members of the Suttle Laboratory of Marine Virology and Microbiology were permitted in December, 2009, to take water samples from several different locations inside the mine. The temperatures inside the cave reach as high as 40 C and a relative humidity between 90 and 100%. As a result chemo autotrophic microbes, at present, ( because of their isolation) and their viruses may be related to those which dwelled on our earth at a much earlier time, or even possibly on other planets. It is hypothesized they exist and thrive in this ecosystem. The researchers from the team explained that â€Å"by working with these samples. We hope to gain insight into what types of microbial assemblages inhabit this very unique environment† (Suttle). In 1997 The National Speleological Society published a book titled â€Å"Cave Minerals of the World. The demands made by the Nomenclatures and Classification Commission on New Minerals and by the International Mineralogical Association were met. In 2011 and up-to-date list added 319 cave minerals. Mineralogy has achieved a rapid growth over the last 10 years. This is mostly due to progress in analytical facilities and new technology. The study of speleothems can teach us about quaternary climate change, and show us the difference between many speleogenetic routes and passages. Minerals can also lead us to understand and re-create landscape evolution. New minerals hold valuable information for the fields of the Earth sciences, and many other disciplines of study. They will answer many questions in the future (ONAC et al. ). According to the University of South Florida, Department of Geology, and other experts in the field â€Å"The result of cave mineral studies, when integrating stable isotope analysis with other microanalytical techniques, can be reassembled to test and improve conceptual ideas in mineral precipitation and to quantify geochemical processes associated with it† (ONAC et al. 4). Important discoveries have been made at the mines in Naica. Here are a few examples: Sulfates- Alpersite and Antlerite- Naica mine, Mexico. Cave at 150m. Silicates- Hectorite- â€Å"Cueva de las Espadas, Naica, Mexico. † Grientite- â€Å"Cueva de los Velas, Naica, Mexico† (ONAC et al. 34-36). There is no reason to assume that the most recent discovery, the â€Å"Cave of Crystals† has nothing to offer. This magnif icent find holds the interest of geologists, microbiologists, Earth scientists and many other allied professionals. They should be permitted, no, encouraged, to learn all they can before the cave returns back to its underwater existence, and is lost to us forever. The traditional study of minerals did not include much direct interest in the cave environment. Cave mineralogy is a field relatively new to science. This inattention stemmed from the fact that 90% of minerals found in caves are composed of aragonite and calcite (Bogdan and Forti, 80). Cave minerals known as speleothems are secondary deposits. Many of them have little or nothing to do with the actual cave itself. They were carried or transported as the existing cave was being filled or by corrosion after-the-fact. (Bogdan and Forti,79-80). Entering the 19th century, less than 10 scientific papers were published, detailing around 10 minerals, only including four different caves. Progress was made. By the 20th century 50 cave minerals were known and 250 papers have been published. The 60s brought with them 700 scientific papers on the subject, and some 80 described cave minerals. The third millennium brought about nearly 5000 papers published about 300 cave minerals and their environments were detailed. Today we average 2 to 3 new mineral each year (Bogdan and Forti, 81). Many of these minerals are new to science. Their surprise wealth is the result of separate forces working together. Percolating water causes the leaching of sediment and rocks before entering the cave. (Leaching releases solid-state radionuclides or contaminants into the liquid state. ) Another factor is high hydrogen sulfide solutions or hydrothermal liquid interplay with the cave sediments and the base rock. The same chemical compounds can form totally different product specimens. In other words completely different results can form from the same exact chemical compounds. The type of reaction that is undergone is the determining factor of the formation that is left behind (Bogdan and Forti,80). A variety of reactions take place in the cave environment. The key factors are: pH, Eh, changes in humidity and temperature, the chemistry of the solution and the presence or lack thereof microorganisms. Some common cave reaction types are: segregation and sublimation- processes result in phase transition. The key mechanism is temperature. Geochemical processes: oxidation/reduction, hydration/dehydration and double replacement these key mechanisms seem to be the concentration of acids (Bogdan and Forti,82). The cave of crystals should be left unharmed and be studied by the scientific community. It holds many answers that will benefit us in many ways. It should then be returned to the state in which we found it. This unique treasure and its knowledge are worth more to mankind than the ore produced by the mine. For the time being the caves should be open for geologists to study while there is a chance, as there is much to be learned.

The Impact of Afterschool Programs within California High Schools Research Paper

The Impact of Afterschool Programs within California High Schools - Research Paper Example This report declares that in the study of the impact of after school programs within California high schools, the variables were debate, church, track, football, baseball, basketball, swim team, lacrosse, soccer, karate, volleyball, tennis, cheerleading, gymnastics, dance, no after school activities, students’ academics and community involvement. Variables are the factors or elements which make up a given argument as they act on each other in various ways. They are the determinants of how a given phenomenon shall turn out to be. There are different types of variables. Generally speaking, there are the dependent variables and the independent variables. The independent variables are those which do not change regardless. This paper makes a conclusion that doctors and psychologists concur that indeed at the high school age, the students have a young body and brain all of which are growing at a very fast rate. There are very many changes that are taking place in the body of the students at this point in time and putting too much stress on them is a recipe for disaster. In this regard, considering the fact that the academic content in high schools is one of the toughest and nerve racking, it is very recommended that a way is devised for taking the stress away from the students. There is no better way than engaging the students in after school programs on a daily basis. It is a source of comfort that is effective in the restoration of sanity to the young minds of the high school students. In the study of the impact of after school programs within California high schools, the variables were debate, church, track, football, baseball, basketball, swim team, lacrosse, soccer, karate, volleyball, tennis, chee rleading, gymnastics, dance, no after school activities, students’ academics and community involvement. Variables are the factors or elements which make up a given argument as they act on each other in various ways. They are the determinants of how a given phenomenon shall turn out to be. There are different types of variables. Generally speaking, there are the dependent variables and the independent variables. The independent variables are those which do not change regardless. They are not affected by any other factors or variables. They are usually factors which are either permanent or are changed by supernatural factors. In this case, they are the students’ academics and community involvement which are always invariable. On the other hand, dependent variables are those which rely on other variables so as to act in a given fashion. They cannot stand on their own as changes which occur on other factors would alter them to behave
