Why is contrast medium used in certain diagnostic tests?
Contrast is typically a dye that helps to outline organs or blood vessels. Flouroscopy, MRIs, or CAT scans can see much of the body structures without contrast, but to obtain more detailed images a physician may order the tests to be done "with contrast". Other types of contrast material may be barium (ex. a "barium swallow" or upper GI with contrast shows the esophagus and stomach) or radioactive (ex. for thyroid testing).
What material is useful for making molds because it has a low melting point?
waxWax
A material used for electrial wiring must have High viscosity low malleability or high conductivity?
If a material is going to be used for electrical wiring, it must have high conductivity. Conductivity is a noun.
What material is used to make bags?
Plastic. Of course they're made out of plastic, The type of plastic is polyethylene. From the low melting point (195F) they are most likely made out of low density polyethylene.
What is hocm?
HOCM is an acronym for several different things such as Hypertrophic Cardiomyopathy and Hypertrophic Obstructive Cardiomyopathy. It also stands for High Osmolar Contrast Medium and High Osmolality Contrast Medium.
What is the difference between high and low contrast?
The difference is that high contrast has more black and low contrast has more white.
What requires a high contrast setting?
Some lenses are very low in quality and therefor low in contrast! That's right, the lens is responsible for how much contrast your picture will naturally have. Catadiopric Telephoto Lenses are known to have very low contrast, so boosting your contrast on your camera helps a lot!
