emitted from the MRI scanner to different areas of the body which results in the protons to fall out of their original position in the body. This is why gradient field coils are used and important in the use of MRI scanners because it serves as a way to set different frequencies for the magnetic field . Without the use of these coils‚ it will be difficult to distinguish through the

form quick sand. Upon this sand bed is a concrete slab with many coil springs and shock absorbers and then a second concrete slab. The structure to be protected is placed on the second concrete slab. In the event of an earthquake‚ the sand bed acts to slow the propagation of seismic waves‚ and spreading them evenly throughout the area of the sand bed. As the seismic waves propagate through the sand‚ it has slowed enough for the coil springs to absorb the rest. The concrete slabs should be of a thickness

S. Having adequate knowledge about crops’ behaviours and characteristics is very essential for the farmers / producers most especially in the field of production. Three examples of specific aspects of crop behaviour that a farmer / producer must know are the plants’ life cycle‚ mode of production‚ and also its growth habit. The plant life cycle begins with a seed. This seed will sprout and produce a tiny immature plant (seedling) which will further mature. This maturation would result to reproduce

At what point is a parent legally bound to take her sick child to a physician instead of treating him with home remedies gleaned off the Internet? That’s the question confronting an Alberta judge who must soon decide if a mother’s withholding of professional medical care from her 7-year-old son‚ who eventually died from an acute bacterial infection‚ was criminal negligence or simply a well-intentioned but misguided decision. It’s the second time this year Alberta parents have landed in court because

increasing. How will we ever stop the highly growing population of Mosquitos? People have used various instruments to control the Mosquito Problems in homes. One of the most popular are the baygon coils which are mostly used. These coils can kill mosquitos yet the active ingredients in these coils like allethrin‚ pynamin forte‚ prothrin and pyrethrin‚ can cause harm to humans when inhaled. It also has an ozone- depleting ingredient. Some even uses insecticide sprays which kills mosquitos but

processes which use a form of wireless energy transfer‚ the ability to provide electrical energy to remote objects without wires using oscillating magnetic fields. The idea of wireless electricity has been around since the early days of the Tesla coil. But thanks to a group of MIT scientists‚ "WiTricity" (as these scientists call it) is now one step closer to practical reality. Demonstrating the ability to power a 60-watt light bulb from a power source seven feet away without wires might not seem

Is your hair then positively or negatively charged? How about the comb? -The hair becomes positively charged and the comb becomes negatively charged; since‚ the electrons went from your hair to the comb and the more electrons there is makes an object more negative. 18)
