S.transition to IFRS Appreciate exercises gained from late business outrages. Segment 1 †THE IMPORTANCE OF Ethics is a significant piece of your bookkeeping instruction and it will assume an inexorably significant job in all parts of your expert life. This module is proposed to give you a review of the investigation of morals. It is a beginning stage for the conversation of morals that will proceed all through the entirety of your bookkeeping examines. We will start with a meaning of morals and afterward survey some moral hypotheses that give a system to creating moral principles for bookkeeping understudies and experts. At long last, we will talk about why morals is critical to you as you get ready for a vocation in bookkeeping. Meaning OF ETHICS What precisely is morals? As per Webster’s Dictionary morals is â€Å"a discipline managing great and abhorrent and moral obligation, and with moral standards and practice. † Accounting morals fundamentally includes applying moral standards to bookkeeping and business choices. Business morals is a progressively broad type of applied morals that relates moral standards to business circumstances. Business morals looks at conduct toward the outside world considering moral standards and business codes of morals. Moral Decisions in Accounting | 1 Simply put, morals is making the best choice. It is difficult to characterize morals since morals can be distinctive for various individuals. You have your very own qualities and these qualities are significant in the choices you make. At the point when you are ready to go you will be required to follow sets of accepted rules that are built up by your organization and by any expert affiliations that you have a place with. Keeping the moral norms of these associations is significant, however you ought to continually bring your very own qualities into your plan of action. Moral THEORIES Philosophers have created numerous speculations to give a structure to settling on moral business choices. These speculations give a perspective to creating implicit rules for organizations and expert affiliations. Most moral codes in business depend on the accompanying good hypotheses: Rights hypothesis. The ethical decision is the decision that best ensures and regards the ethical privileges of those associated with a choice. This hypothesis proposes that people have a respect that depends on their human instinct and their capacity to uninhibitedly pick what they do with their lives. Along these lines they reserve an option to be treated as finishes and not just as intends to different closures. Utilitarian hypothesis. The moral activity is the activity that gives the most great or does the least damage. The moral business activity is the one that delivers the best great and does minimal damage for all who are affected†business partners, for example, clients, representatives, investors, the network, and the earth. Basic great hypothesis. The connections of society are the premise of moral thinking and regard and empathy for others is the reason for moral choices. This hypothesis tends to the regular conditions that are critical to the government assistance of everybody. Temperance hypothesis. Moral activities ought to be reliable with perfect temperances that accommodate the full advancement of humankind. Genuineness, fortitude, sympathy, liberality, resilience, love, loyalty, honesty, reasonableness, poise, and reasonability are instances of temperances. Decency hypothesis. Moral activities treat every person genuinely dependent on some standard that is solid. We may pay individuals progressively, in light of the trouble of their work or the more noteworthy sum that they add to an organization. Significance OF ETHICS Information gave by bookkeepers and evaluators is depended upon by individuals who settle on choices about organizations and associations. For instance, in the event that you are thinking about purchasing stock in an organization you need precise and solid data whereupon you can base your choice. Moneylenders, for example, banks and monetary establishments need solid data to decide whether they will advance cash to organizations. Government offices, for example, the Internal Revenue Service gather charges dependent on the budgetary data gave by organizations. Individuals depend on the bookkeepers who get ready budgetary reports. Information on morals will assist you with making great choices that will give appropriate data to the individuals who depend on you. With legitimate data, better choices will be made. 2 | Ethical Decisions in Accounting Business choices can influence numerous individuals or partners. For instance, when you settle on a choice for your organization it can influence the proprietors and workers of the organization, banks who give assets to the organization, clients of the organization, and individuals in the network where the organization is found. Notwithstanding the impact of your choice on the benefits of the organization, your choice may likewise have other non-money related elements that effectsly affect partners. Imagine a scenario in which you were thinking about two elective tasks for your organization: (1) a venture that would make huge benefit for your organization and furthermore dirty nature with unsafe synthetic concoctions; (2) another undertaking that would procure less benefit yet would have no negative impacts on the earth and would not hurt any partners. Which venture would you pick? Ought to non-monetary elements go into the choice procedure? In the event that you consider factors that are not financial just in nature, at that point how would you measure them? Regularly, the most significant factors in a choice are the ones that can't be effectively estimated. Since certain things can't be estimated effectively, in any case, doesn't imply that we ought not think about them in our choices. That is the primary concern about the significance of morals in accountingâ€an mindfulness that morals is a significant piece of business choices. We frequently utilize the money saving advantage choice model to assess business ventures. We list the expenses on one side and the advantages on the opposite side and the more noteworthy number regularly chooses the task. On the off chance that the advantages are more noteworthy than the costs we acknowledge the task; if the expenses surpass the advantages the undertaking is dismissed. Where does morals fit into the procedure? More Profit Less Profit Ethical issues merit a spot in the costbenefit model. It is actually very simple†you consider the potential expenses and advantages of moral issues and spot them on the scale alongside different expenses and advantages. Since moral issues frequently are troublesome or difficult to quantify doesn't imply that they are not significant or that they ought not be considered in the choice. A progressively moral choice is probably going to result if moral components are in any event brought into the image when settling on business choices. Once more, familiarity with the moral ramifications of business choices is the way to great business choices. Not all choices utilize the money saving advantage model. A few choices include picking various approaches, for example, recording bookkeeping exchanges when various choices are accessible under proper accounting rules. You should pick the right activity as indicated by the conditions in question, and not founded exclusively on the measure of benefit your organization can make. As the U. S. advances toward receiving universal bookkeeping guidelines, the bookkeeping direction will be founded more on standards than on explicit principles. The utilization of judgment will probably assume an increasingly unmistakable job in settling on bookkeeping decisions and moral standards will play a much progressively significant job in business choices. Moral Decisions in Accounting | 3 DISCUSSION QUESTIONS 1. Before long you will move on from school and find a new line of work. What moral implicit rules will you need to follow? By what means will your own qualities influence your business choices? What punishments are there for inability to adhere to moral guidelines? 2. Take a gander at the moral guidelines of the AICPA or the IMA remembered for segment 4 of this module. What standards will manage you in settling on bookkeeping decisions? Area 2 †THE HISTORY OF ETHICS IN ACCOUNTING In the wake of later, prominent bookkeeping outrages, you may believe that morals is a moderately new point to the field of bookkeeping. All things considered, morals has been a significant piece of bookkeeping since techniques for keeping monetary records picked up force in the thirteenth century. A code of morals currently applies to all bookkeeping experts and morals has become a basic element of bookkeeping training. BRIEF HISTORY OF ETHICS IN ACCOUNTING Luca Pacioli, an Italian mathematician and Franciscan minister, depicted a technique for keeping money related records in 1494 when he distributed his first book Summa de Arithmetica, Geometria, Proportioni, et Proportionalita (interpreted â€Å"everything about number-crunching, geome

Hello! I would like to schedule a meeting with Senator Markey.

“Hello! I would like to schedule a meeting with Senator Markey.” A little over a month ago, the American Astronomical Society posted the following announcement: I originally became a AAS member in order to present my research at AAS conferences, and membership turns out to provide valuable access to new opportunities. In this case, I realized that the dates were during my spring break, said heck yeah, and applied. On Valentines Day, I got a message saying that Id been accepted, and within a week received a whole bunch of homework. Book your travel Get to know your group Schedule meetings with your senators and representatives My group consists of myself, a PhD student from Georgia, and a solar astrophysicist at Harvard. The AAS has a whole website on how to contact and schedule meetings with representatives, so I read through that in order to get myself from Zero Knowledge to Some Knowledge.  My fellow Massachusetts resident and I divided up the labor so that Im in charge of scheduling meetings with Senator Ed Markey and Representative Michael Capuano, and shes in charge of getting hold of Senator Elizabeth Warren and Representative Katherine Clark. Now, Im normally very happy to pick up the phone and call whoever, but something about calling a Senators office and requesting a personal meeting with him (or one of his science/tech staffers) freaked me out. This afternoon, I drank a cappuccino and in a fit of (possibly caffeine-boosted) confidence resolved to finally make the call. It rang twice, and then, Man: Senator Markeys office, how may I help you? Me: Um. [suddenly completely unable to speak English] Me: Um, yes, hello. May I please speak with Senator Markeys scheduler? Man: Whos calling, please? Me: Oh, yes, um, hello. [thinking: DARN, I already said that!] Im SenatorI mean, no, sorry. Im a constituent of Senator Markeys, living in Cambridge. [thinking: did I really just almost say that Im Senator Markey?] Im going to be in Washington DC on Mach 26th to represent the American Astronomical Society as part of the Congressional Visits D- Man: Okay, the scheduler is currently out of her office, but Ill transfer you to her voicemail. Me: Okay, thank you! I left a message, and am in the middle of composing a follow-up e-mail. Phew. Definitely not a smooth start to my science research advocacy career, but sometimes the hardest part is just picking up the phone for the first time, and Im already over that mental hurdle.

Einsteins Theory of Relativity

Einsteins theory of relativity is a famous theory, but its little understood. The theory of relativity refers to two different elements of the same theory: general relativity and special relativity. The theory of special relativity was introduced first  and was later considered to be a special case of the more comprehensive theory of general relativity. General relativity is a  theory of gravitation  that  Albert Einstein developed by  between 1907 and 1915, with contributions from many others after 1915. Theory of Relativity Concepts Einsteins theory of relativity includes the interworking of several different concepts, which include: Einsteins Theory of Special Relativity - localized behavior of objects in inertial frames of reference, generally only relevant at speeds very near the speed of lightLorentz Transformations - the transformation equations used to calculate the coordinate changes under special relativityEinsteins Theory of General Relativity - the more comprehensive theory, which treats gravity as a geometric phenomenon of a curved spacetime coordinate system, which also includes noninertial (i.e. accelerating) frames of referenceFundamental Principles of Relativity What Is Relativity? Classical relativity (defined initially by Galileo Galilei and refined by Sir Isaac Newton) involves a simple transformation between a moving object and an observer in another inertial frame of reference. If you are walking in a moving train, and someone stationary on the ground is watching, your speed relative to the observer will be the sum of your speed relative to the train and the trains speed relative to the observer. Youre in one inertial frame of reference, the train itself (and anyone sitting still on it) are in another, and the observer is in still another. The problem with this is that light was believed, in the majority of the 1800s, to propagate as a wave through a universal substance known as the ether, which would have counted as a separate frame of reference (similar to the train in the above example). The famed Michelson-Morley experiment, however, had failed to detect Earths motion relative to the ether and no one could explain why. Something was wrong with the classical interpretation of relativity as it applied to light ... and so the field was ripe for a new interpretation when Einstein came along. Introduction  to  Special Relativity In 1905,  Albert Einstein  published (among other things) a paper called  On the Electrodynamics of Moving Bodies  in the journal  Annalen der Physik. The paper presented the theory of  special relativity, based  on  two postulates: Einsteins Postulates Principle of Relativity (First Postulate):  The laws of physics are the same for all inertial reference frames. Principle of Constancy of the Speed of Light (Second Postulate):  Light always propagates through a vacuum (i.e. empty space or free space) at a definite  velocity, c, which is independent of the state of motion of the emitting body. Actually, the paper presents a more formal, mathematical formulation of the postulates. The phrasing of the postulates  are  slightly different from textbook to  textbook  because of translation issues, from mathematical German to comprehensible English. The second postulate is often mistakenly written to include that the speed of light in a vacuum is  c  in all frames of reference. This is actually a derived result of the two postulates, rather than part of the second postulate itself. The first postulate is pretty much common sense. The second postulate, however, was the revolution. Einstein had already introduced the  photon theory of light  in his paper on the  photoelectric effect  (which rendered the ether  unnecessary). The second postulate, therefore, was a consequence of massless photons moving at the velocity  c  in a vacuum. The ether no longer had a special role as an absolute inertial frame of reference, so it was not only unnecessary but qualitatively useless under special relativity. As for the paper itself, the goal was to reconcile Maxwells equations for electricity and magnetism with the motion of electrons near the speed of light. The result of Einsteins paper was to introduce new coordinate transformations, called  Lorentz transformations, between inertial frames of reference. At slow speeds, these transformations were essentially identical to the classical model, but at high speeds, near the speed of light, they produced radically different results. Effects of Special Relativity Special relativity yields several consequences from applying Lorentz transformations at high velocities (near the speed of light). Among them are: Time dilation (including the popular twin paradox)Length contractionVelocity transformationRelativistic velocity additionRelativistic doppler effectSimultaneity clock synchronizationRelativistic momentumRelativistic kinetic energyRelativistic massRelativistic total energy In addition, simple algebraic manipulations of the above concepts yield two significant results that deserve individual mention. Mass-Energy Relationship Einstein was able to show that mass and energy were related, through the famous formula  Emc2. This relationship was proven most dramatically to the world when nuclear bombs released the energy of mass in Hiroshima and Nagasaki at the end of World War II. Speed of Light No object with mass can accelerate to precisely the speed of light. A massless object, like a photon, can move at the speed of light. (A photon doesnt actually accelerate, though, since it  always  moves exactly at  the speed of light.) But for a physical object, the speed of light is a limit. The  kinetic energy  at the speed of light goes to infinity, so it can never be reached by acceleration. Some have pointed out that an object could in theory move at greater than the speed of light, so long as it did not accelerate to reach that speed. So far no physical entities have ever displayed that property, however. Adopting Special Relativity In 1908,  Max Planck  applied the term theory of relativity to describe these concepts, because of the key role relativity played in them. At the time, of course, the term applied only to special relativity, because there was not yet any general relativity. Einsteins relativity was not immediately embraced by physicists as a  whole  because it seemed so theoretical and counterintuitive. When he received his 1921 Nobel Prize, it was specifically for his solution to the  photoelectric effect  and for his contributions to Theoretical Physics. Relativity was still too controversial to be specifically referenced. Over time, however, the predictions of special relativity have been shown to be true. For example, clocks flown around the world have been shown to slow down by the duration predicted by the theory. Origins of Lorentz Transformations Albert Einstein  didnt create the coordinate transformations needed for special relativity. He didnt have  to because the Lorentz transformations that he needed already existed. Einstein was a master at taking previous work and adapting it to new situations, and he did so with the Lorentz transformations just as he had used Plancks 1900 solution to the  ultraviolet catastrophe  in  black body radiation  to craft his solution to the  photoelectric effect, and thus develop the  photon theory of light. The transformations were actually first published by Joseph Larmor in 1897. A slightly different version had been published a decade earlier by Woldemar Voigt, but his version had a square in the time dilation equation. Still, both versions of the equation were shown to be invariant under Maxwells equation. The mathematician and physicist Hendrik Antoon Lorentz proposed the idea of a local time to explain relative simultaneity in 1895, though, and began working independently on similar transformations to explain the null result  in  the Michelson-Morley experiment. He published his coordinate transformations in 1899, apparently still unaware of Larmors publication, and added time dilation in 1904. In 1905, Henri Poincare modified the algebraic formulations and attributed them to Lorentz with the name Lorentz transformations, thus changing Larmors chance at immortality in this regard. Poincares formulation of the transformation was, essentially, identical to that which Einstein would use. The transformations apply to a four-dimensional coordinate system, with three spatial coordinates (x,  y,   z) and  one-time  coordinate (t). The new coordinates are denoted with an apostrophe, pronounced prime, such that  x is pronounced  x-prime. In the example below, the velocity is in the  xx direction, with velocity  u: x (  x  -  ut  ) / sqrt ( 1 -  u2  /  c2  )y   y z   z t {  t  - (  u  /  c2  )  x  } / sqrt ( 1 -  u2  /  c2  ) The transformations are provided primarily for demonstration purposes. Specific applications of them will be dealt with separately. The term 1/sqrt (1 -  u2/c2) so frequently appears in relativity that it is denoted with the Greek symbol  gamma  in some representations. It should be noted that in the cases when  u  Ã‚  c, the denominator collapses to essentially the sqrt(1), which is just 1.  Gamma  just becomes 1 in these cases. Similarly,  the  u/c2  term also becomes very small. Therefore, both dilation of space and time are non-existent to any significant level at speeds much slower than the speed of light in a vacuum. Consequences of the Transformations Special relativity yields several consequences from applying Lorentz transformations at high velocities (near the speed of light). Among them are: Time dilation  (including the popular Twin Paradox)Length contractionVelocity transformationRelativistic velocity additionRelativistic doppler effectSimultaneity clock synchronizationRelativistic momentumRelativistic kinetic energyRelativistic massRelativistic total energy Lorentz Einstein Controversy Some people point out that most of the actual work for the special relativity had already been done by the time Einstein presented it. The concepts of dilation and simultaneity for moving bodies were already in place and the mathematics had already been developed by Lorentz Poincare. Some go so far as to call Einstein a plagiarist. There is some validity to these charges. Certainly, the revolution of Einstein was built on the shoulders of a lot of other work, and Einstein got far more credit for his role than those who did the grunt work. At the same time, it must be considered that Einstein took these basic concepts and mounted them on a theoretical framework which made them not merely mathematical tricks to save a dying theory (i.e. the ether), but rather fundamental aspects of nature in their own right. It is unclear that Larmor, Lorentz, or Poincare intended so bold a move, and history has rewarded Einstein for this insight boldness. Evolution of General Relativity In  Albert Einsteins  1905 theory (special relativity), he showed that among inertial frames of reference there was no preferred frame. The development of general relativity came about, in part, as an attempt to show that this was true among non-inertial (i.e. accelerating) frames of reference as well. In 1907, Einstein published his first article on gravitational effects on  light  under special relativity. In this paper, Einstein outlined his equivalence principle, which stated that observing an experiment on the Earth (with gravitational acceleration  g) would be identical to observing an experiment in a rocket ship that moved at a speed of  g. The equivalence principle can be formulated as: we [...] assume the complete physical equivalence of a gravitational field and a corresponding acceleration of the reference system. as Einstein said or, alternately, as one  Modern Physics  book presents it: There is no local experiment that can be done to distinguish between the effects of a uniform gravitational field in a nonaccelerating inertial frame and the effects of a uniformly accelerating (noninertial) reference frame. A second article on the subject appeared in 1911, and by 1912 Einstein was actively working to conceive of a general  theory of relativity  that would explain special relativity, but would also explain gravitation as a geometric phenomenon. In 1915, Einstein published a set of differential equations known as the  Einstein field equations. Einsteins  general relativity  depicted the universe as a geometric system of three spatial and one time dimensions. The presence of mass, energy, and momentum (collectively quantified as  mass-energy density  or  stress-energy) resulted in a bending of this space-time coordinate system. Gravity, therefore, was movement along the simplest or least-energetic route along this curved space-time. The Math of General Relativity In the simplest possible terms, and stripping away the complex mathematics, Einstein found the following relationship between the curvature of space-time and mass-energy density: (curvature of space-time) (mass-energy density) * 8  pi G  /  c4 The equation shows a direct, constant proportion. The gravitational constant,  G, comes from  Newtons law of gravity, while the dependence upon the speed of light,  c, is expected from the theory of special relativity. In a case of zero (or near zero) mass-energy density (i.e. empty space), space-time is flat. Classical gravitation is a special case of gravitys manifestation in a relatively weak  gravitational field, where the  c4  term (a very big denominator) and  G  (a very small numerator) make the curvature correction small. Again, Einstein didnt pull this out of a hat. He worked heavily with Riemannian geometry (a non-Euclidean geometry developed by mathematician Bernhard Riemann years earlier), though the resulting space was a 4-dimensional Lorentzian manifold rather than a strictly Riemannian geometry. Still, Riemanns work was essential for Einsteins own field equations to be complete. What Does General Relativity Mean? For an analogy to general relativity, consider that you stretched out a  bed sheet  or piece of elastic flat, attaching the corners firmly to some secured posts. Now you begin placing things of various weights on the sheet. Where you place something very light, the sheet will curve downward under the weight of it a little bit. If you put something heavy, however, the curvature would be even greater. Assume theres a heavy object sitting on the sheet and you place a second, lighter, object on the sheet. The curvature created by the heavier object will cause the lighter object to slip along the curve toward it, trying to reach a point of equilibrium where it no longer moves. (In this case, of course, there are other considerations -- a ball will roll further than a cube would slide, due to frictional effects and such.) This is similar to how general relativity explains gravity. The curvature of a light object doesnt affect the heavy object much, but the curvature created by the heavy object is what keeps us from floating off into space. The curvature created by the Earth keeps the moon in orbit, but at the same  time, the curvature created by the moon is enough to affect the tides. Proving General Relativity All of the findings of special relativity also support general relativity, since the theories are consistent. General relativity also explains all of the phenomena of classical mechanics, as they too are consistent. In addition, several findings support the unique predictions of general relativity: Precession of perihelion of MercuryGravitational deflection of starlightUniversal expansion (in the form of a  cosmological constant)Delay of radar echoesHawking radiation from black holes Fundamental Principles of Relativity General Principle of Relativity:  The laws of physics must be identical for all observers, regardless of whether or not they are accelerated.Principle of General Covariance:  The laws of physics must take the same form in all coordinate systems.Inertial Motion is Geodesic Motion:  The world lines of particles unaffected by forces (i.e. inertial motion) are timelike or null geodesic of spacetime. (This means the tangent vector is either negative or zero.)Local Lorentz Invariance:  The rules of special relativity apply locally for all inertial observers.Spacetime Curvature:  As described by Einsteins field equations, the curvature of spacetime in response to mass, energy, and momentum results in gravitational influences being viewed as a form of inertial motion. The equivalence principle, which  Albert Einstein  used as a starting point for general relativity, proves to be a consequence of these principles. General Relativity the Cosmological Constant In 1922, scientists discovered that application of Einsteins field equations to cosmology resulted in an expansion of the universe. Einstein, believing in a static universe (and therefore thinking his equations were in error), added a  cosmological constant  to the field equations, which allowed for static solutions. Edwin Hubble, in 1929, discovered that there was redshift from distant stars, which implied they were moving with respect to the Earth. The universe, it seemed, was expanding. Einstein removed the cosmological constant from his equations, calling it the biggest blunder of his career. In the 1990s, interest in the cosmological constant returned in the form of  dark energy. Solutions to  quantum field theories  have resulted in a huge amount of energy in the quantum vacuum of space, resulting in an accelerated expansion of the universe. General Relativity and Quantum Mechanics When physicists attempt to apply quantum field theory to the  gravitational field, things get very messy. In mathematical terms, the physical quantities involve diverge, or result in infinity. Gravitational fields under general relativity require an infinite number of correction, or renormalization, constants to adapt them into solvable equations. Attempts to solve this renormalization problem lie at the heart of the theories of  quantum gravity. Quantum gravity theories typically work backward, predicting a theory and then testing it rather than actually attempting to determine the infinite constants needed. Its an old trick in physics, but so far none of the theories have been adequately proven. Assorted Other Controversies The major problem with general relativity, which has been otherwise highly successful, is its overall incompatibility with quantum mechanics. A large chunk of theoretical physics is devoted toward trying to reconcile the two concepts: one which predicts macroscopic phenomena across space and one which predicts microscopic phenomena, often within spaces smaller than an atom. In addition, there is some concern with Einsteins very notion of spacetime. What is spacetime? Does it physically exist? Some have predicted a quantum foam that spreads throughout the universe. Recent attempts at  string theory  (and its subsidiaries) use this or other quantum depictions of spacetime. A recent article in New Scientist magazine predicts that spactime may be a quantum  superfluid  and that the entire universe may rotate on an axis. Some people have pointed out that if spacetime exists as a physical substance, it would act as a universal frame of reference, just as the ether had. Anti-relativists are thrilled at this prospect, while others see it as an unscientific attempt to discredit Einstein by resurrecting a century-dead concept. Certain issues with black hole singularities, where the spacetime curvature approaches infinity, have also cast doubts on whether general relativity accurately depicts the universe. It is hard to know for sure, however, since  black holes  can only be studied from afar at present. As it stands now, general relativity is so successful that its hard to imagine it will be harmed much by these inconsistencies and controversies until a phenomena comes up which actually contradicts the very predictions of the theory. Quotes About Relativity Spacetime grips mass, telling it how to move, and mass grips spacetime, telling it how to curve — John Archibald Wheeler.The theory appeared to me then, and still does, the greatest feat of human thinking about nature, the most amazing combination of philosophical penetration, physical intuition, and mathematical skill. But its connections with experience were slender. It appealed to me like a great work of art, to be enjoyed and admired from a distance. — Max Born

Physics of Microwaves Essay - 981 Words

Physics of Microwaves Microwaves are used in our everyday lives but most most people dont realize that physics plays a large and important part in the simple household item. Whenever we heat our food we are oblivious to the forces that cause such a thing to occur and we dont fully understand what happens in front of our eyes and how our food really gets heated in such a simple and efficient way. The first thing people need to understand is that microwaves are actually electromagnetic waves. Wavelengths and frequencies range from 300 MHz up to 300 GHz but, the average microwaves at home or restaurants operate at frequencies of about 2.45 GHz. Microwaves consist of a waveguide, magnetron, fan, power supply and a turntable with the†¦show more content†¦Microwaves have to have a source and that source is the device known as the magnetron. The magnetron is basically an electric field existing in the gap os the device. Magnetrons also consist of a cylindrical cathode running throu gh the centre and the outside of the tube, formed by several cavities acting as anode and takes shape. With all this it allows the electric field to exist at the center. Perpendicular to the electric field is where the parallel to the tube length is where the permanent electric field. Located in the cathode, electrons are stripped into the electric field due to the thermionic emission which is high temperatures in the cathode exciting the electrons to make it be released. Once this is done they are accelerated to the anode, the outside of the tube, because of the forces applied to them from the electric field. Another force is also applied to them as they are on their way which is the magnetic field and this curves their motion. With their curved motion the places where there are excess negative charges in the anode is where the electrons are pushed towards. Negatives charges are then pushed back and around the cavity creating an oscillation of electric and magnetic fields caused by the moving electrons and charges. The waves emitted from the magnetron are faced towards the spinning propellor that is made of metal.

Moreover, the human digestive system cannot digest certain plant proteins, and this can lead to stomach problems.

Factors that influence on food choices Food choices are influenced by many factors, age, gender, friends, family, cultural background and where we live. Although the main purpose of food is to nourish the body, food means far more than that to many people. It can represent much of who and what we are. People bond and foster relationships around the dinner table and at celebrations with special meals and foods, such as birthday cake. Some people express their creative side by serving dinner guests, as well as expressing their awareness and appreciation for others. Some people also use food to help them cope with stress by overeating or depriving themselves. Food may also be used as a reward for accomplishing a specific goal. Consequently, what people eat can reveal much about who they are socially, politically and religiously. Factors influencing food preferences include: Taste, *texture* *and* *appearance*. Economics – The cost of food affects what we eat. Our early experiences with food – Food preferences begin early in life and change as we are exposed to new people and places. As children, our choices were in the hands of our parents. However, as we get older, our experiences with new people and places increase, thereby broadening our food preferences and choices. Habits – Most of what we eat from a particular core group of foods. About one hundred items account for 75 percent of the foods most people eat. Having a narrow range of food choices provides us with security. For example, going to a particular fast-food restaurant provides common expectations and experiences. Many people also have the cooking habits of our mothers or grandmothers. Culture – Religious rules can affect food choices. For example, Hindus do not eat beef, and some Jewish people do not eat pork. The region that people are from can also affect eating behaviors. Swedish people would not eat an ear of corn, because it is considered food for hogs. In Russia, we don’t normally eat insects, but many other cultures regard them as preferred foods. Culture can also dictate the times to eat and what to eat at certain meals. Advertising – To capture the interest of the consumer, food producers spend billions of dollars each year on advertising and packaging, both for food bought in grocery stores and restaurants. The power of persuasion is very strong, and so food producers and restaurants try to make their products as appealing as possible to consumers, even if that means making false claims. Social factors – Social changes have a big effect on the food industry. Our fast-paced society demands drive-through restaurants. Gas stations now have convenience stores and restaurants attached to them, so people can do one-stop shopping. Malls also cater to their customers with food courts offering a wide variety of foods.

Women in the Civil Rights Movement Essay Example For Students

Women in the Civil Rights Movement Essay When I think about the Civil Rights Movement of the 1960s, the first person that comes to mind is Dr. Martin Luther King, Jr., whom for me and many others was the embodiment of the Civil Rights Movement. My knowledge of the Civil Rights Movement in the 1950s and 1960s has been limited to Dr. Martin Luther King, Jr. and Malcolm X. I dont think that this limitation has anything to do with information not being documented, but for the fact that society tends to place an individual, particularly a male, upon a platform and focus upon that one person as being the significant leader of the cause. I do not necessarily disagree with this approach, but unfortunately, many people become excluded and unrecognized for their contributions for the same cause. Just as many have the conception that the Civil Rights Movement in itself began in the 1960s. On the contrary, that was far from the beginning of the fight for freedom by African Americans. The fight for freedom and equality began when the first slaves were shipped to this country, there was always a will to be free and a struggle to obtain that freedom. We will write a custom essay on Women in the Civil Rights Movement specifically for you for only $16.38 $13.9/page Order now For the purposes of this discussion, I will focus on another group that may have been somewhat overlooked within the Civil Rights Movement. The Women in the Civil Rights Movement Essay of the 1950s and 1960s, who were not only contributors, but supported, worked extremely hard, and dedicated their lives in the fight for equal rights in this country. Without the women that were involved in Civil Rights Movement, Dr. King would not have been able to accomplish as much as he did. African American women played a more significant leadership role in the Civil Rights Movement than what chroniclers typically acknowledge. (Lisa Crumrine Klionsky, News UC Davis). Besides the more visible black male leaders of the Civil Rights Movement, both black and white women played important and key roles in the struggle for racial equality. Womens experiences in the Civil Rights Movement can tell us a lot about the lives of ordinary and extraordinary women and their ability to access and be denied power in a movement for black liberation that was based on the idea of equality. There was an inherent contradiction within the movement for although many women were doing much of the organizing work; they still remained largely invisible while the men shone in the spotlight. Women of all different social classes and racial backgrounds participated in many different capacities throughout the Civil Rights Movement. Women that were involved in the movement could be found working behind the scenes or in the trenches along side the men helping to bring about social change throughout the movement. They could be found putting their bodies on the line in protest at s egregated lunch counters, on buses for Freedom Rides travelling throughout the segregated South, as well as working door-to-door on voter registration drives throughout the South. (University of Florida: The Role of Women in the Civil Rights Movement). Traditionally, women have played a role in the growth and development of children, and children are still strongly influenced by women, but, little emphasis has been placed on where, when, why and how women have assisted in shaping this country. Based on Charles Payne study of the Civil Rights Movement, women involved in the Civil Rights Movement canvassed more than men, showed up more often at mass meetings and demonstrations, and frequently attempted to register to vote. (Crawford, Rouse and Woods, p. 2). Because sexism and racism intersected, women involved in the Civil Rights Movement had to not only have the strength to stand up for the rights of African-Americans, but also to be able to stand up to the sometimes one-sided views of the men involved in the movement. .uf71e6b5e0253dd119266af661ba190cc , .uf71e6b5e0253dd119266af661ba190cc .postImageUrl , .uf71e6b5e0253dd119266af661ba190cc .centered-text-area { min-height: 80px; position: relative; } .uf71e6b5e0253dd119266af661ba190cc , .uf71e6b5e0253dd119266af661ba190cc:hover , .uf71e6b5e0253dd119266af661ba190cc:visited , .uf71e6b5e0253dd119266af661ba190cc:active { border:0!important; } .uf71e6b5e0253dd119266af661ba190cc .clearfix:after { content: ""; display: table; clear: both; } .uf71e6b5e0253dd119266af661ba190cc { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .uf71e6b5e0253dd119266af661ba190cc:active , .uf71e6b5e0253dd119266af661ba190cc:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .uf71e6b5e0253dd119266af661ba190cc .centered-text-area { width: 100%; position: relative ; } .uf71e6b5e0253dd119266af661ba190cc .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .uf71e6b5e0253dd119266af661ba190cc .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .uf71e6b5e0253dd119266af661ba190cc .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .uf71e6b5e0253dd119266af661ba190cc:hover .ctaButton { background-color: #34495E!important; } .uf71e6b5e0253dd119266af661ba190cc .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .uf71e6b5e0253dd119266af661ba190cc .uf71e6b5e0253dd119266af661ba190cc-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .uf71e6b5e0253dd119266af661ba190cc:after { content: ""; display: block; clear: both; } READ: Wuthering Heights (784 words) Essay There are several women who were leaders, who had the strength and courage to fight and advocate for freedom and equality.
