Homework Answers
a) Hot water bags :
It is generally used for relieving pain by providing warmth while in bed but can also be used to provide heat to any specific part of the body. Modern hot water bags are generally made up of rubber.
Advantages : could remain in the bed. Rubber could withstand sufficient heat.
Disadvantages : faulty rubber may not withstand very high heat and could melt. Hot water could leak through the stopper.
b) Electric heating pad :
It is generally used to relieve pain by providing warmth to any part of the body. It functions by the use of electric current. It is mainly used by the physiotherapists.
Advantages : can be used dry because it does not requires hot water. There is no chance of water leakage.
Disadvantages : sometimes can cause overheating and electric shocks.
c) Hot packs :
It is also generally used by physiotherapist to relieve the pain. They are applied over the exposed area that needs treatment
Advantages : decreases pain, relaxes tight muscles, and increases blood circulation.
Disadvantages : could not be used in areas of altered sensitivity and persons who are sensitive to heat.
d) Warm moist compresses :
It is generally used to remove the dirt and debris from eyes. They also relieves pain and plays a significant role in dry eye syndrome.
Advantages : promotes quick healing, reduce inflammation and causes vasodilation.
Disadvantages : Very high heat can damage the eyes.
e) Sitz bath :
It is used to relieve pain in the lower part of the body. In this method, the person sits in water up to the level of his hip.
Advantages : relieves congestion, pain, and swelling in the lower half of the body.
Disadvantages : sometimes can cause palpitations and dizziness.
f) Warm soaks :
It relieves pain, swelling, and promotes blood circulation by immersing a part of the body in warm solution. It is also used to clean the wounds.
Disadvantages : sometimes high heat can damage the skin.

Recently there have been many research groups looking at the use of metallic nanoparticles for cancer treatment. For example, one can imagine injecting magnetic nanoparticles into a tumor, heating them with infra-red radiation and having the hot nanoparticles kill the tumor. This has advantages in that one doesn’t have to use toxic chemicals throughout the body. But will it work? Suppose our nanoparticle has a radius of 3 nm. a) Use the viscosity of water to estimate the diffusion constant...

Food Microbiology Purpose To utilize the process of fermentation to make yogurt To describe organisms responsible for food borne illnesses and summarize a recent outbreak Introduction Microorganisms have been used for centuries for food preservation and to improve or change its taste. Evidence exists that yogurt, which is milk fermented by bacteria, has been around for over 4000 years. Today, many of the foods we eat are the result of microorganisms acting on foods for a specific and desired effect....

Principles of Inorganic Chemistry! Week 5 Effect of Temperature on Solubility of a Salt In this experiment, you will study the effect of changing temperature on the amount of solute that will dissolve in a given amount of water. Water solubility is an important physical property in chemistry, and is often expressed as the mass of solute that dissolves in 100 g of water at a certain temperature. In this experiment, you will completely dissolve different quantities of potassium nitrate,...
