Question 1: Explain the key difference between irritation and allergic contact dermatitis.
Contact dermatitis refers to a condition in which the skin becomes sore, red or inflamed after direct contact with a foreign substance. There are two types that include irritant and allergic contact dermatitis.
Irritant dermatitis occurs after a body comes into contact with acid or alkaline material. It can also be caused by other materials such as a soap detergent, fabric softeners, solvents and any other chemical that get into contact with the body. The irritation is usually confined to the specific area that the body came ...

There are various ions that are responsible for the acidic or basic nature of a substance. The hydrogen ions and hydroxide ions are both responsible for the acidic and basic nature of substance respectively. A neutral substance contains equal number of hydrogen ions (H+) as well as hydroxide ions (OH-) An acid is substance that dissolve and donate hydrogen ions leading to more number of hydrogen ions in a solution. A substance that dissolves water and release hydroxide ions is considered a base. A base has more number of hydroxide ions as compared to hydrogen ions hence basic.
Alkalinity ( ...

INFRARED SPECTROPHOTOMETRY AND ORGANIC CHEMISTRY

Infrared Spectrophotometry and Organic Chemistry
Infrared (IF) Spectrophotometry is designed to determine the sample by measuring infrared radiation absorption of wavenumbers within the region of 4,000-400 cm-1 at different wavenumbers, as it passes through the sample. This technique employs the property that the IF absorption spectrum of the material is typical of its chemical structure. IR spectra are demonstrated in charts drawn via plotting on the abscissa and the absorbances or transmittances on the ordinate. Except when indicated, when the spectrum of the sample is the same in the intensity of absorption at a similar wavenumber to the ...

Introduction
The Human Papilloma virus (HPV) is an extremely common group of viruses that are found worldwide. There are more than 100 types of HPV worldwide. 13 types of HPV are associated with cancer. They are also termed as high risk type. (WHO, 2013). HPV is transmitted through sexual contact. More than 90% of cases are infected shortly after sexual activity. Cervical cancer is associated with HPV infection that are acquired through sexual contact. 70% of cervical cancer cases are caused by two types of HPV. HPV 16 and HPV 18 are the two strains associated with cervical ...
