A while back I remember reading a bizarre article about a woman who ran a business, The Snuggery where the owner of the business, Jacqueline, provides individuals with private therapeutic (non-sexual) snuggling sessions that are meant to have many psychological and physical health benefits. In the article it explained how simple affectionate touch and physical contact with others can have a positive effect on our physical and mental health by decreasing anxiety, stress, and depression, while…

The Mayak Cohorts is a study of workers who lived in a closed city of Ozyorsk in Russia. It benefites from a stable population. In addition to that excellent dose records have been kept. Regular medicals occur with smoking and alcohol data recorded. 3 Cohorts were set up ; plant workers; residents living near the Techa river; offspring of the local Techa river population. ICRP Update It was necessary to update ICRP 60 to ICRP 103 as the Life Span Study had an extra 10 plus years of follow up.…

COMPOSITION OF UNIVERSE As we know, the Universe comprises of space, time and everything perceived to exist physically including all forms of matter and energy and interaction going on between them. Space and time are two basic correlates of universe. In these correlates there is matter and energy scattered around. There is interaction going on between matters, energies and between matter and energy on account of endless processes. These processes are governed by universal laws as explained in…

creates less collateral damage usually seen in external beam radiotherapy. Protocol for both of the radiation therapies is 3,500 to 4,000 centigrays (cGy) of radiation. A Gray is defined by the International System of Units (SI) by the absorption of one joule of radiation energy by one kilogram of matter. For that reason, the protocol allows for 35-40 Grays of radiation. (Bascom Palmer Eye Institute, University of Miami School of…

The Deflation Effects on a Soccer Ball How could a ball affect a game? How could the speed it is moving at affects how it is received. Can the way to control the ball be affected by how stiff or hard the ball is. Can the air pressure of the ball affect the bounce of the ball. Can the little thing about a soccer ball affect such a large game of soccer. The pounds per square inch, or PSI, of a soccer ball can affect a lot of things but it does not give an advantage to any team over another since…

Both diesel engines and gasoline engines are internal combustion engines, which means they are designed to make mechanical energy by converting chemical energy available in fuel. Rotary motion is required to turn the wheels of a car forward. So to make this rotary motion, pistons connected to a crankshaft move in an up and down motion to create the rotary motion. Through a series of small combustions or explosions, diesel engines and gasoline engines convert fuel into energy. Diesel and…

consumption, which currently generates more than a third of America’s electricity. A transition to renewable energy can be difficult for numerous reasons. First we can simple evaluate the scale. The global use of fossil energies were about 1x10^18 joules in 2012, that’s 20 times greater than it was in the 1890s, as coal overtook wood. Generating this much energy with any new source is intimidating, and a significant amount of it will derive from the United…

The energy that gets dissipated is proportionally equivalent to kTln2 joules of energy for one bit of information loss, where k=1.38 x 10-23 J/K is Boltzmann constant and T being the absolute temperature. C H Bennett [2], proposed that the joules of energy will not be dissipated from the system if the operations are performed using reversible logic and the system can reproduce the inputs from the observed…

can be used for Nuclear Fission as you could find out the total amount of energy in joules that is inside the the reactor. Remember Fission bursts into two daughter cells and also creates energy, this is where the equation comes in and calculates it. In Nuclear Fusion energy is given off when two small high energy nuclei combine/collide, the equation could then be used here to work out the total energy in joules. Fossil fuel power and Nuclear power plants both give out an enormous amount of…

enough energy to reach the speed of light. In 1905, Einstein, using his special theory of relativity showed that mass is actually just another form of energy and that in fact, they are equivalent. Equation E=mc2, (E=the energy released by an object in joules, m= the change in mass of an object in kg, c= the speed of light which is 3x108m.s-1. Outline the discovery of the expansion of the Universe by Hubble, & its earlier prediction by Friedmann Friedmann proved mathematically that the universe…
