The physical properties of glass and polymer materials PMC
Majority of plastic materials are opaque and the surface reflection of light off the plastic determines amount of gloss on the surface. The crystalline nature of a polymer determines their optical properties.The use of photolithography in printing integrated circuits has orchestrated improvement in the transmission glasses for the ultraviolet (UV) region (Malik and Raina 2004). This is done to enhance the physical properties of the material and to acquire an effective product in the

The last five years have seen a major push for the use of 3Tesla in clinical settings
These reactions are explained with Larmour frequency equations (James, 1998, pp1-31; Machann et., 2008, pp63-70).These nuclei momentums align either parallel or anti parallel with the surrounding magnetic field based on the law of quantum physics. Hence, this creates energy difference among the spins that in turn allows transition in between the states. Nucleus consumes energy and goes into excitement phase and further resting or relaxation phase. This relaxation period is important for

Submarine Volcano
(Palande, 2011)This debris is either piled-up around the volcanic vent or settles down along the seafloor. (Topinka, 2003) Eventually the piling up emerges above the surface of the ocean in the form of volcanic islands, some of which can be seen in the south Pacific and the north Atlantic oceans.) (Crouse 2012).In the deeper part of the ocean, volcanic activity pretty much resembles the volcanoes on land terms of shape and flows (Topinka, 2003). They are seen to be slightly steeper as the water

Magnetic Resonance Instrumentation :Phased Array Coils: What are the Pros and Cons
The overall time from scanning to image reconstruction is still lower compared to alternatives. The report tells us how the process can be further improved by improving technologies tied to image processing, to improve image quality and image reconstruction times.The overall picture one has from the discussion on parallel imaging is this: parallel imaging techniques using phased array coils are highly flexible. They also have high SNR characteristics. Essentially, parallel imaging can allow for

Explain some of the things in common between todays hybrid cars (like the Prius) and a futuristic maglev train (with specific attention to electromagnetic propulsion and braking)
Similarly, they perceive that a hybrid car model is unsafe, as the driver has no control of the car. They argue that with the car using two sources of power, the fossil fuel powered engine and the generator/motor power, the driver has little control of the car. Similarly, the fact that the maglev train has no engine and acts on an electromagnetic field around the tracks and the walls makes them relatively prone to accidents or braking failures. Others point out that the fields in some instances

Note: This is 2 separate papers on geology. (each paper 2 pages)
According to Ralph & Cheryl, (2001), the difference between a thrust fault and a reverse fault is that a reverse fault usually has a steeper dip of more than thirty degrees. These two faults form inside divisions of the crust that are experiencing compression. A convergent plate boundary is usually a region of major reverse and thrust faults; however these two faults also crop up in other settings where the crust is being compressed (Ralph & Cheryl, 2001).In a strike-slip fault, the rock blocks

Comparative Critical Review
According to Tipler and Gene (297), whenever the internal energy of a system increases it results to an elevation in temperature leading to the alteration of matter’s state such as solids melt to liquid whereas liquid into gas. Tipler and Gene state that a cooked potato usually undergoes some changes; this is due to the rapid exchange of joules in and of the potato such that while 100 joules of energy go into the potato, similarly 90 joules come out (Tipler & Gene, 2007, p.

It was released at the speed of about 3000 feet per second but did not pass through the concrete that was placed underneath and neither did it penetrate the ballistic skin recreated in the lab. The latter was a skull covered by gel that mimicked human skin, so it was slightly reliable; this was necessary for safety reasons and also to enhance the repeatability of their actions.The results were measured using a high speed camera, visual observation and determination of terminal velocity of the

Brain eating amoeba
Furthermore, pharmaceutical firms are especially reluctant to fund expensive research, which is unlikely to yield returns since its very low demand.From a business point of view, this might sound logical but taking to account some of the isolated cases and the potential for more infection albeit small, one is forced to question the morality of such reasoning. Take the case of Hally a 9-year-old Kansas girls who died after a case of the amoeba. It is suspected she had been infected after

Electron microscopy
After focusing the beams by the condenser lens, the highly concentrated electron beam then strikes in a different chamber that is sealed by a carefully prepared known as O-rings. The specimen prepared is what the beam of light passes through in order to magnify it. The varying levels of material density also play a vital role in the magnification process since the beam is also made of particles. This is what influences the lightness or the darkness of the final image that is viewed by the

Relationship between Einstein and Dostoevsky, how science is related to art
Emanating from his work, is summed up in a quote attributed to the scientist, with regard to how Dostoevsky, according to Einstein, is able to provide more to Einstein in comparison to any scientist, and in particular more than what Gauss had given him. This is not a trivial quote, and can be construed as a recognition from Einstein that what Dostoevsky gave him in terms of a vision from the arts is more than what science had been able to provide him up until that point in his life. Here then

The answers for this comparison of movement takes the structure where xm is the abundancy of the swaying, and φ is the stage steady of the wavering. Both xm and φ are constants dictated by the starting condition (intial uprooting and speed) at time t=0 when one starts watching the oscillatory movement.Longitudinal waves are waves whose energy transfer is in the same direction as the displacements in the medium in which they propagate. In addition, they can have one or many pulses. They have

The vibrations associated with the earthquakes makes the rocks underground to break. This leads to release of lots of energy from beneath the ground. This energy is very strong and is capable of causing massive destructions to the landscape itself, infrastructure, structures as well as property (Brumbaugh, 2010). Moreover, the energy released from the underground following the incidences of earthquake can sometimes result to massive loss of lives.In most instances, the energy from the

Rock and soil in saudi arabia
The rock around which crude oil is formed is known as the reservoir rock. From here, crude oil accumulated towards the earths surface and gets trapped beneath the impermeable rock to form an oil reservoir. Saudi Arabia, unlike other countries where oil is extracted, is predominantly a desert region. This means that the oil tanks are trapped under layers of sandy soils where the impermeable rock is. In Saudi Arabia, most oil deposits are associated with sandstones as well as limestone with

Below the water table, all spore spaces are saturated with water. This zone is known as phreatic zone. There is a substrate that slight porosity and allows little transmission of ground water. This substrate is called an aquitard. Aquifers have diverse features depending on the geology, and the structure of the substrate as well as the topography in which they happen. Aquifers that contain a high amount of water are situated in sedimentary geologic formations. Crystalline rocks that are

Global Warming
Plants play an enormous role in maintaining the worlds temperature. Plants use the carbon dioxide in the air and convert it into stored energy. When plant absorbs carbon dioxide, they release oxygen. The oxygen the combines with hydrogen to form water that precipitates as rain. Cutting down plants destabilizes the balance by increasing the level of carbon dioxide. The excess carbon dioxide becomes trapped in the air. Trapped carbon dioxide creates an insulation for the suns rays, thus increases
