NM Spectra

Nuclear magnetic resonance (NM) spectroscopy is one of the most powerful and versatile techniques available to determine the arrangement of atoms in the structure of a molecule. Organic molecules composed principally of hydrogen and carbon atoms can be analyzed using techniques of proton (1H) and carbon-13 (13C) NM spectroscopy. The basic interpretation of the NM spectra for a molecule observes several properties including the strength and intensity of the magnetic field used to produce a peak, the interaction of the atom with atoms around it and the effects of neighboring atoms on spectra themselves. Analysis of the relative location of a peak in an NM spectrum (called the chemical shift) and the splitting of that peak can provide significant information about the structure of a molecule. More detailed information about molecular structure can be determined through 2-dimensional techniques where the NM pulses producing a magnetic field are combined…

Quantum mechanics is a theory that has emerged in the study of both chemistry and physics and has been received with a lot of enthusiasm. Nobel laureate physicist Philip Anderson goes as far as naming quantum mechanics the greatest invention of the last 2000 years, describing its impact saying,

The quantum theory forces a revision of our mode of thinking, which is far more profound than Newtonian mechanics or the Copernican revolution or relativity... It tells us that we really completely know the rules of the game which all these particles and quanta are playing, so that if we are clever enough we can understand everything about ourselves and our world. In other words, there is no "why" question about our everyday world that the quantum theory can't answer for is - Why is the sky blue? Why is glass transparent? What holds DNA together? Why does the sun shine?…

Bias of Authors Regarding America Dropping the Atom Bomb on Japan

This paper examines what has been written about the dropping of the atom bomb on Japan, following the attack on Pearl Harbor. The writer details several articles and explores where the writer is coming from and what may have led to a particular slant on a story regarding the bomb. There were six sources used to complete this paper.


The atom bomb was dropped on Japan to make a statement to the world. It was not just that the U.S. wanted Japan to understand attacking Pearl Harbor was wrong, but Japan was the example the United States made for the world. The message was loud and clear that if the U.S. is attacked the enemy will be hit back ten fold and then some. In addition to it being…

The Golgi receives new proteins and lipids from the ER, finishes them up, addresses them and sends them to their final destination. In this way, the Golgi could be the postal service of the city. Lysosomes get rid of unusable waste within the cell and recycles those materials that can be reused, making it the recycling and garbage center of the city. Mitochondria are where ATP, the main energy molecule, is made. It could be considered the city's power plant. Then we have the cell's cytoskeleton, which gives the cell its shape, strength and its ability to move. It can be looked at as the roadways and bridges of the city.

What are the steps of scientific method? What good is it? Does it prove anything? What's a variable? What a control vs. An experimental factor? What makes a good experiment?

Steps of scientific method:

Ask a question

Do background research

Construct a hypothesis

Test your hypothesis

Analyze your data

f. Communicate your results

The scientific method is good because it allows other scientists to repeat your experiment and all researchers to use the same method of investigation.

A variable is the thing in an experiment which varies from subject to subject.

A control in an experiment is the thing that remains the same. Experimental factors are the factors that are being tested and are changing.

e. Good data and accurate experimentation make a good experiment.

The Tacoma Narrows Bridge collapsed on November 7, 1940. Incredibly, the whole collapse was caught on tape. atching the tape, it is clear that the bridge collapsed from instability caused by enormous waves moving with periodic motion through the structure of the bridge. It is not clear, however, what caused this wave motion in the first place, or what caused it to get progressively worse until it destroyed the bridge. The cause of the collapse of the bridge continues to be a subject of debate among engineers.

" (Avogadro)

His most well-known contribution to the field of chemistry was the statement titled; the Avogadro constant or Avogadro number. Avogadro stated that "a mole equals 6.022 x 1023." (American) It also states that equal volumes of gases, at the same temperature and pressure have the same amount of molecules.

Avogadro's number really means the number of molecules in a mole. His number is essential in chemistry because it calculates the amount of pure substances in stoichiometric relationships. It also determines how much heavier a simple molecule of one gas is than that of another. This number is also very large 6.0221367x10^23. However, Avogadro only hypothesized this and he was not responsible for calculating it, Loschmidt was. (Furtsch)

Even though, Avogadro was not fully responsible for the discovery of the mole, he did solve many controversies and gathered enough research for other scientists, like Loschmidt, to calculate. His curiosity…

To -179 C, mean that ethynyl's highly reactive status is necessary to perform the chemical process that results in the creation of triacetylene and the polyynes that serve as ultraviolet radiation shields and appear as haze from a distance (About that, 2009, Scientific Blogging). Saturn is otherwise too cold to have the heat to propel chemical reactions, in the absence of reactive molecules like ethynyl.

The modeling techniques used by the scientists to reproduce this process involved crossed molecular beam machines to "collide supersonic gaseous beams of ethynyl and diacetylene molecules," and a mass spectrometer measurement of the reaction (About that, 2009, Scientific Blogging). Analysis confirmed that the results of the collision yielded triacetylene, plus a single hydrogen atom. Later computations also confirmed the spectrometer's analysis of the distribution of electrons in…

abundant elements that occur in living organisms are as follows: carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorous. These and all elements are made up of atoms, which are the primary units of matter. Molecules are groups of atoms that are covalently bonded. Covalent bonds occur when two atoms share one or more pairs of electrons. This is different from ionic bonds, which arise when an electrical attraction between two oppositely charged ions takes place. Elements are substances that cannot be chemically dissected into simpler kinds of matter. Compounds, however, are atoms of two or more elements that are united by chemical bonds.

The parts of an atom include protons, neutrons, and electrons. These are all called subatomic particles. Protons, which are part of the nucleus of an atom, have positive electrical charges. Neutrons, which are also part of the nucleus of an atom, and as the name indicates, are neutral…

, 2006). he proponents of the theory utilizing this method argue that open-ended questions require children productive use of information they already know, unaided by an external representation of the earth (e.g. globe or any other 3-D model). Using this method, superficial (memorization-based) knowledge is eliminated. his enables the experimenters to find out whether children fully understand the information they know (Vosniadou, Skopeliti, & Ikospentaki, 2005).

Using the forced-question method, on the other hand, results in less ambiguous answers. When an external 3-D model of the earth accompanies this style, more scientifically correct responses are obtained because the model gives a cue (Panagiotaki, et al., 2006). However, most of the forced questions used by the proponents of the second theory are biased towards a spherical model of the earth (Panagiotaki, et al., 2006). So in the end, the results may not be truly representative of what children do know if…

That being said, it may never be too early to expose children to situations where she might begin to explore the dual representation nature of the globe. Even if a child hasn't reached an age where she understands that the earth is in fact a sphere, parents and teachers can lay the groundwork by talking about it in class or going to science exhibits and museums. Callanan et al. (2002) reviewed some strategies for effective parent-child conversations about representational objects, but unfortunately, most are applicable to concrete, rather then abstract concepts. However, they brought into focus the importance of social interaction within which children experience representational objects.

By integrating the social context of the globe-earth link and the theories on children's earth concepts, a likely overall interpretation about children's understanding of the earth could be this: Children can be trained to learn scientifically correct understanding of the earth using the globe as an external model and by giving them fragments of information when opportunities arise, to help them develop their own coherent and non-literal interpretation.

Finally, the lessons learned from the earth-globe research findings can be applied to other abstract concepts in science like atoms, gravity, and evolution. With modern technology and advances in computer-aided design, it is possible to create interesting models of an atom or a visual representation of gravity and evolution in museum or exhibit settings. Children can explore these models while teachers or parents engage them by providing simple information that focus on a particular aspect that the child is interested in. At home, parents and children can look at science picture books or videos and label the objects they see represented on the pages or videotape. In other words, there are various opportunities and many accessible representational objects that can be used to lay the groundwork for children to build a coherent understanding of abstract principles.

living things are characterized by the following seven characteristics namely mobility, respiration, excretion, sensitivity or response to external stimulus, growth, feeding, and reproduction. Though there may be variations between animal and plant kingdom (ex, plants take in carbon dioxide and prepare their own food), these characteristics are commonly observed among all living things.

iology is a very broad field that encompasses the study of characteristics of living things. It includes botany, zoology and all other sub-disciplines that range from microbiology to evolution and ecology.

Evolution is the branch of biology that deals with the study of natural development of living organisms and the changes in them over time. Evolution refers to the heritable changes that occur in a population over a period of time. All the diversity that is observed currently in plant and animal kingdom can be ascribed to evolution over a long period of time.

I think your insight that Walt Whitman's "Song of Myself" is not about egotism is very apt. In fact, Whitman's poem is the very opposite of egotism. You write: "Song of Myself" seems "to focus specifically on himself, as Whitman begins by declaring, 'I celebrate myself, and sing myself' but America for Whitman is about more than simply the glorification of the individual. He also understands the significance of the nation's history as he explains, 'My tongue, every atom of my blood, formed from this soil, this air, Born here of parents born here from parents the same, and their parents the same.'" Whitman believes that America is a nation which frees individuals to express themselves, and celebrating himself is, by extension, celebrating America.

Similar phenomena can be argued regarding "interviewer bias" where the race, gender, words, appearance, or other factors such as behavior of the interviewer may have an effect on the interviewee. Some wording effects may be understood in certain ways due to the experience or cultural background of the respondent, for instance, and he may misinterpret or misunderstand them. Wording effects can be reciprocal too with the interviewer misunderstanding words or tone of the respondent. All of these (and other factors) may serve to corrupt the study

Alternative theories, based on the Heisenberg Uncertainty Principle, would be best followed up, if matter is the stuff which one wants to transport. The Heisenberg Principle states that it is impossible to know where any part of a physical object is at any point in time. Therefore, to know where every atom of our body is at any given time is impossible. If your blood is moving through your veins, then the atomic particles which make up your blood are moving rapidly from one part of your body to another and it is impossible to know at any particular moment where one of these atoms may…

This information is utilized to create new products and substances that are used on a regular basis. For example, chemists could use the COSY process to understand how to create a new kind of raincoat that will be even more water resistant. To determine this, the protons inside the molecules of the raincoat would have to be examined through the COSY process. This will identify the peaks inside the protons and what specific attributes are similar to other compounds. Once this happens, is when scientists can use this as a way to create specific attributes that they are looking for (i.e. A raincoat that is more waterproof). This is significant, because it is showing how the contribution of the COSY methodology allows chemists to create new compounds with specific attributes. ("Thomaston," 2006)

Symmetry in Inorganic Chemistry

Molecules are often classified in terms of their symmetry. All molecules that have the same basic shape share a number of common properties. Classification of molecules by symmetry is based upon the presence of symmetry "elements," such as mirror planes and rotational axes, and corresponding symmetry "operations" such as reflection through such a plane and rotation about such an axis, shared by all molecules in a given "point" group. A symmetry operation is a real or imagined change that can be made to the molecule that leaves it in an indistinguishable position from the initial position. For example, if a benzene molecule were rotated by 60, 120, 180, 240 or 300 degrees about it's principle axis of rotation, the molecule will be left in an identical configuration with respect to the initial one. Any molecule said to have C2v symmetry (or to "belong" to the C2v…

Mixture and a Compound

Three main terms are usually used in the field of chemistry. These are element, compound and a mixture. These three will be the element of key discussion in the paper.

There is a great difference between a mixture and a compound. A compound is formed from two elements that combine together chemically by sharing electrons. The physical and chemical properties of the constituent elements are different in the beginning in their individual states from the physical and chemical properties of the final compound. Thereby the final chemical as well as physical properties of the compound are determined by the elements. On the other hand, a mixture may have many constituent compounds, or elements that are mixed (Bettelheim, Brown, Campbell, and Farrell, 2008, p. 45). The constituent elements of the compound cannot be separated physically but in the case of mixture, the constituents can…

Leaves digest the sunlight, produce nutrients, live, grow, die, and fall to the ground. The wind bears aloft the leaves, scatters them over earth and sea. The tide moves them, pushes them up into rivers where at last they settle into the mud. Salmon swim upstream; lay their eggs on the muddy bottoms of lakes and rivers. A powerful grizzly bear nuzzles the icy water of a mountain brook. His great paw sweeps into the water and catches a darting salmon. Men come; establish a city on the banks of the stream.

The concepts of energy and matter are slightly more intuitively understood, but before reading the passage a class discussion that attempts to define tese terms would also be useful.

After reading the passage once, the question of what substances are elements could be put to the class. No doubt some substances such as water will be listed that are basic compounds, and not true elements. These answers can then be used to illustrate the interaction of atoms and elements to create other substances that are not pure elements. At the same time, this will help illustrate the way different elements can form different substances depending on atomic structure. This in turn leads into Fermi and the splitting of an atom.

When this portion is reached, students can be asked what the parts of an atom are. Students can also be asked to explain how magnets work; this discussion will take…

Management Strategy to Utilize Meta-Analysis Technique for Nuclear Energy and Waste Disposal and Create Social Sustainability

This research proposal explores the link between public perceptions of nuclear power, how those perceptions are formed, and what influence those opinions have on energy policy. These issues are important in light of two realities. First, nuclear energy is declining in its share of global energy. Second, nuclear energy offers what might well be the best solution to climate change. Given the threat posed by climate change, it makes sense that nuclear power would be increasing in share, not decreasing. This esearch proposal seeks to look at some of the issues facing nuclear power, and how it can overcome these issues to increase share going forward.

"Buckyballs" are the roundest and most symmetrical large molecule that is known. They are geodesic domes with the same essential symmetry -- C60 the third major form of pure carbon and graphite and diamond the other two. Buckyballs can come in any sizes and other atoms can often get trapped inside them. Chemists at Yale University, in fact, managed to trap helium and neon inside buckyballs and it was the first time chemists ever observed helium and neon inside a compound of any kind (232). Buckyballs can be manufactured as well to fit a certain size requirement (232).

In the "Chemistry in Action" about trans-forming fats, we learn that when oil is converted into a solid fat, some of the double bonds are converted to single bonds by adding hydrogen. This is the process known as hydrogenation and it is easier with cis double bonds and thus the remaining double bonds are chiefly in the trans configuration. Studies have shown that these trans fats because they are so unnatural can be very bad for our health and can lead to high cholesterol, heart disease, and diabetes (230). Because trans fats are now known to be detrimental to a person's health, manufacturers have been required since January 1, 2006 to label the trans fat content in food products (238).

The direct selling strategy will be a website that will include a product configuration application. A distribution partner portal will also be created which gives distributors and dealers the ability to customize the Liberta Ultralight in quantity for their customers as well. The use of channel strategies to actively promote the use of mass customization as a product differentiator will also be accomplished through intensive dealer and channel training (Swiercz, Lydon, 388). Finally the use of an integrated Partner Relationship Management (PRM) system that will give channel partners the flexibility to provide resellers with support on a 24/7 basis will also be created. The intent is to create enough support for channel strategies so they can produce up to 60 -- 70% of overall revenue for the product line.

Mixtures are composition of two or more substances which are not chemically combined and do not exist in fixed proportions to each other. For instance when you take two components, an iron and Sulphur powder, the two when mixed together can be separated by physical means since they are not chemically combined i.e. with the use, of a magnet. Mixtures have the following characteristics which differentiates it from compounds. They include; mixtures can be disintegrated by the use of a physical method, the substance which form the mixture normally retain their properties, mixtures do not have a sharp melting point, they also have no fixed composition, and lastly a mixture…

Radiation can be described as energy that is in the form of streams or waves of particles. Numerous types of radiation surround us. When most individuals hear the term radiation, the thing that comes to their mind is nuclear power, radioactivity, and atomic energy. Radiation, however, has several other forms. Visible light and sound are some familiar kinds of radiation. Other kinds of radiation include television and radio signals, infrared radiation (some type of heat energy), and ultraviolet radiation (responsible for suntans). The earth together with occupants are always subjected to radiation produced by the sun, stars as well as other galactic sources and from the radioactive substances found on the earth’s crust. Here on earth, being exposed to radiation is unavoidable as a result of the radioactive materials present in the air, water, and also within the body. Radiation cannot be seen, but it occurs in form if…

Beta particles are identical to electrons according to all measures that have been conducted in this regard, rendered distinct only by the fact that they are emitted from radioactive substances (Bodner, 2011). Other types of radiation also exist, but alpha and beta particles are the primary drivers of basic nuclear reactions (Bodner, 2011; Loveland et al., 2006). adioactive decay -- the result on the source substance of emitting of radioactive particles -- occurs at an exponentially decreasing rate over terms known as the "half life," which is the amount of time it takes for one-half of a quantity of a given radioactive element to transition to a lighter element through its loss of alpha particles (with incidental beta particle emission, as well, though this does not fundamentally change the element) (Carpi, 2003).

The above equation can also be utilized to calculate conduction loss from a human body to ambient air. For example, for a 1.5 tall man wearing dry, insulating clothing, the rate of conductive heat loss on a cold day (ambient temperature at 0oC, normal skin temperature at 37oC) can be calculated as 178W. For the same person wearing wet clothing, however, the equivalent rate is 2,565W. This significant difference in heat losses explains the onset of hypothermia when someone is exposed to ice-cold water or rain (Forinash, 2010). Conduction takes place on a microscopic level as particles of kinetic energy are transferred between two different systems (Abbott, et al., 2005). When atoms and/or molecules heat up, vibrate, or move rapidly, some of their energy gets transferred to other atoms and molecules that are in close proximity. In other words, heat is transferred to the surrounding particles and away from the…

His writings point at the fact that every bit of matter is eternal and thinks. Moreover, the reasoning that there is a common source for all the thought in the universe is impossible since it has always been equally distributed all over the world.

Nuclear Energy
Nuclear energy is an energy source that has zero emissions, propels our society into the future, and provides electricity around-the-clock. Nuclear energy comes from the splitting of atoms inside a reactor through a process known as fission to heat water into steam, turn a turbine, and generate electricity. Atoms are tiny particles that make up every object in the universe. These atoms have enormous energy in the bonds that hold them together. Nuclear fission will split the atoms into smaller atoms, in essence, releasing energy. Nuclear power plants make use of nuclear fission for the production of electricity. Nuclear energy is considered to be environmentally safe because it causes zero emissions and this is beneficial to the environment as it reduces the carbon footprint (Brook & Bradshaw, 2015). However, nuclear power plants do produce radioactive nuclear waste that must be stored safely to ensure there is no…

Describe the difference between a mixture and a compound

The standard definition of a mixture is a substance in which two or more separate components are mixed together, but no chemical reaction occurs. Also, there is no fixed ratio of substances necessary for the mixture to take place. In the case of a compound, the atoms of the different, separate component substances are bonded together, thus creating an entirely new substance. A fixed ratio is usually required for the chemical transformation to take place and the compound to result. A mixture can be easily separated into two component parts, a compound…

or, to put it another way, "chemistry carried out with the primary object of investigating the workings of nature is what we now call physical chemistry" (Laidler, 5). This has made the distinction between physics and chemistry at this frontier very difficult to define. This fuzzy distinction is also one of the things that makes the discipline of physical chemistry so interesting -- it cannot deny the complete interweaving of scientific disciplines.

Physics and chemistry lay out the foundation and explain the mechanisms of all other sciences, and the field of physical chemistry is the closest unification of these two sciences. All biological and astronomical processes only occur because of reactions and interactions at the molecular and atomic level, and physical chemistry attempts to explain these underlying principles (Laidler, 9). Though the nature of energy and matter is still not fully understood, physical chemistry is approaching better and better explanations…

Differences between scientific models and religious myths

There are several approaches toward s the creation issue, some of them are scientific and others are religious. All the approaches are postulates towards the search for the cradle of man. They may therefore be divided into scientific models and religious myths. Although people view these theories and models from different perspectives, they too have their similarities. Therefore this paper will contain an in depth study of the two different ideologies that is from the religious view on creation and the scientific view of creation. The types of theories that will be discussed here will be the big bang theory which will be a scientific view and the creation theory which is based from the religious point-of-view. An in depth look into the evolution theory will be looked at.

Lagow et al. reported the synthesis of a terminally capped linear acetylenic carbon with alternating single and triple binds, claiming it to be a stable sp carbon allotrope (1994), a subject of debate as the classification of acetylenic carbon as an allotrope continues to be determined, and the stability of such a compound is in question. The proposed structure and stability of a linear sp carbon of such a proposed length and with alternating single and triple bonds is disputed by Hirsch et al. Thus, the stability of long-chain carbon allotropes and the characterization of the linear sp carbon synthesized by Lagow et al., given its terminal end design, remains in question as to the…

Magnetic esonance Imaging

History of MI

The Magnetic esonance Imaging (MI) was first tested in Budapest Hungry in 1882. Later in 1937, Professor Isidor abi of Columbia University assembled a Nuclear Magnetic esonance. This tool was effective because it could absorb and emit radio waves after exposure to a strong magnetic field. Professor Carr Herman produced one-dimensional MI imaging processor in 1952. The nuclear powered NM was instrumental in experiments developed to detect the presence of tumors in normal cells. However, the technology was fully adopted in 1973 when Lauterbur Paul successfully produced the first NM image (Lauterbur, 1973). Previously, Damadian created the NM imaging machine in 1972, but not until 1973 did Lauterbur apply it for imaging. Following the success, Peter Mansfield developed an arithmetical methodology that was vital in integrating the concept to real-time problems.

Before the emergence of this concept, magnetic scans took hours to process. However,…

The Greeks believe that the soul is an essential part of the body since it gives it life. The soul thinks, feels, and chooses[footnoteRef:1]. The interaction between the body and soul influences one another giving rise to the concept of dualism. They also view the soul as a simple form without any parts. Plato postulated that the soul is separated from the body and while the body degenerates, the soul leaves to form another life at death[footnoteRef:2]. Contrastingly, Aristotle considered the soul as a ‘form’ that cannot exist without the body. The following study explicates Aquinas’s views of the soul whilst appreciating the contribution given by Plato and Aristotle on the topic. [1: Terrance, W.

Another lesson learned by the fusion research has been its impact on the development of future nuclear weapons vs. existing test ban treaties. It would be possible with successful nuclear fusion results to test weapons without an actual above or below ground explosion due to the nature of the science. The question is raised whether that would be a violation of the nuclear test ban treaties. Also, the potential power of these weapons is mind-boggling -- perhaps 100x existing nuclear weapons. They make the atomic and hydrogen bombs look like firecrackers in comparison.

The mere thought of pure fusion weapons has given pause for thought, and the development of even minor successes in this field cause lessons to be learned about the future control and management of fusion devices.

At almost an hour after the Big Bang, all nuclear material has bonded, yet the temperatures is "still too high for protons and electrons to bind together" to form atoms. From this point on to about 700,000 years later, the temperature has dropped sufficiently and allows electrons and protons to bind together to create atoms of hydrogen. Therefore, as free electrons "are bound up in atoms, the primary cross-section leading to the scattering of photons is removed" which allows the universe to alter from being opaque to transparent, thus allowing photons of light to travel freely in this newly-created universe ("The Hot Big Bang" 2007, Internet).

Epicurus' philosophy is a profound testimony of how science and rational observation can provide a moral guide for humanity. For example, the fact that everything is made up of the same basic matter acts as a reminder that it is necessary to treat the environment with respect, as both human beings and the world are made up of the same basic atomic essence, and their material essence obeys the same properties. People might object that it is easy to use Epicurean philosophy to justify living for pleasure. But Epicurus actually obeyed a moderate diet and lifestyle. Yes, technically one is morally free under Epicurean philosophy to seek pleasure by sitting in bed all day, drinking beer and eating doughnuts. But really, Epicurus would note, that goes completely against his philosophy of true happiness as tranquility and simplicity. hat will make you truly happy?

Radiometric Dating

In 1896, French physicist, Henry Becquerel discovered the natural radioactive decay of uranium, opening new vistas in science (Time pp). Roughly a decade later, in 1905, British physicist Lord Rutherford, "after defining the structure of the atom," first suggested the use of radioactivity as a tool for measuring geologic time (Time pp). Then, in 1907, radiochemist B.B. Boltwood, a professor at Yale University, published a list of geologic ages based on radioactivity, and although his "ages" have since been revised, they do show correctly that the duration of geologic time "would be measured in terms of hundreds-to-thousands of millions of years" (Time pp). The next forty years saw a great deal of research concerning the nature and behavior of atoms, thus, leading to the development of nuclear fission and fusion as energy sources, however, a byproduct of this research has been the development and the on-going refinement of…

Symbols, the Mind, and the Animal State

In Chapter 7 of Maps of Time, David Christian (2011) discusses how human language is built not only of "icons" and "indices," which are types of recognition, correlation, and communication that many organisms from bacteria to dogs can use, but primarily of symbols -- a more complex and higher-order level of communication (p. 172). This is only part of a larger discussion on the development of human history, however it is worthy of consideration simply as its own advancement and unique feature. An understanding of how language is a definitive feature of humanity, and of the implications of a division between man and nature, creates valuable insights for understanding human development.

As explained by Christian (2011), certain associations can be made by many organisms between similar or concurrent experiences in a way that might appear to be symbolic learning or communication,…

Fuel Cells in Green Engineering

The energy tomorrow is beginning to be available today. Fuel cells, which just a very few years ago were a pipe dream, are becoming g a reality, and they are used in areas ranging from space exploration to toy motivation (Joy). The promise of the fuel cell can be seen in the fact that they use the most abundant source of energy on the planet, Hydrogen atoms (Birch). They are also being seen as the energy savior because they emit a common, non-toxic waste which can also be utilized as a saving grace around the globe, water (Joy; Patturaja). A fuel that uses the most abundant element on the planet and emits clean, pure water does seem like science fiction, but there are already being used with it as a motive force.

The space shuttle has always been powered by hydrogen fuel cells (Joy). Although…

What if Ice did not Float?

This is an interesting question that confounded people for many years. In letters between correspondents in different regions of Arabia, the question was bandied, and answered. The thought was that when water froze in a container that it did contract. Thus the void where the water had been formed a vacuum and the heavier air in the outside of the flask caused the water container to implode because of the vacuum that was formed. However, one of the correspondents, the one writing the original query to a more learned colleague, found that the flasks broke out, not in as was indicated in the original explanation. The more experienced of the two did have an explanation of this,

But it is more metaphysical than scientific. He said frozen water creates a space between itself and the container, and that this space desires to be…

Robotics: How Close Are e to Creating a Bionic Man?

hile the creation of a 'bionic man' similar to the Six Million Dollar Man of the 70s television series or the gun-slinging robot of estworld may still be the realm of popular sci-fi, technology has developed to a stage where we are closer to such a possibility than ever before. Some of these technologies include robotics, the development of organic polymers that could be used as artificial muscles, nano-technology, and artificial intelligence (AI). In this paper we will review the latest developments in the relevant technologies to find how close we are to developing a 'bionic man.'

Apart from the availability of the required technology, one of the factors that would eventually determine if (or how soon) we are able to develop a bionic man is -- the urgency or need for such a development. This is because technology does…

Stalin, Mao and broken promises are examined and put together in a story of history. There were eight sources used to complete this paper.

Currently the world is focused on disarming itself from a nuclear standpoint. America has invaded Iraq on the pretext of forcing the nation to stop nuclear technological advancement and while this is going on North Korea is gearing up its formerly defunct nuclear program. It seems that the world is working to reverse a technology that for many years was the race of success. Two of the largest areas in the world spent years competing with each other for power, and they believed that power was going to be found in nuclear technology. China and the former USS…

Polymer Analysis (Kevlar)

Brief History of Kevlar Development

In response to innovations in military armaments, the search for improved body armor for military and law enforcement personnel has been the focus of intense research for several decades. One of the resulting products of this research, Kevlar, is the closest humans have come to matching the tensile strength of spider silk is five times stronger per weight than steel and is best known for its use in bulletproof vests (Ehrenfeld, 2000). Kevlar shares something in common with matches, COBOL, antifungal antibiotics, pulsars, vitamin A, Cepheid variable stars, radium, and mobile genes, in that all of these were discovered or invented by women (Brownlow, Jacobi & ogers, 2000). Kevlar was developed at DuPont by a team comprised of Stephanie Kwolek, Herbert Blades, and Paul W. Morgan. In 1978, Kwolek also produced from aramids the first polymeric liquid crystals (Stevens & Kauffman, 2004).…
