Some studies show that a saline solution restores moisture to dry nasal passages and sinuses, and curbs inflammation of mucous membranes. If you use a Neti pot or a small squirt bottle for saline irrigation regularly, it can help to thin mucus, give you less postnasal drip, and cleanse your nasal passages of bacteria. What types can I use? You can buy an over-the-counter saline solution or make one at home. Most over-the-counter saline nasal sprays are isotonic, which means the solution is the same saline concentration as in your body. Hypertonic versions have a higher concentration of salt than whatâs in your body. Both types can help clear mucus. Saline sprays also help keep the cilia in your nose healthy.
We define human factors as: the study of all thefactors that make it easier to do the work in theright way. Another definition of human factors is the study ofthe interrelationship between humans, the toolsand equipment they use in the workplace, and theenvironment in which they work [1]. One can apply Human factors knowledge towherever humans work.
The textbook definition for R Factor is: the quantity determined by the temperature difference, at steady state, between two defined surfaces of a material or construction that induces a unit heat flow through a unit area.he C factor stands for Thermal Conductance Factor. The C factor, like the K factor, is a rate of heat transfer through a material. The lower the C factor, the better the insulating properties of the material. It is the quantity of heat that passes through a foot of insulation material.
