It refers to any women's clothing that meets the requirements of Sharia, and in Western societies - the traditional Islamic headscarf for women. Wearing of hijab by a woman is one of the main provisions of the Islamic statute - Sharia. Some governments encourage and even oblige the women to wear the hijab, some prohibit. Continue reading...

Sample and ethics

It is very important that ethics be the key influence in any research. In this study, attractiveness is conceptually defined following the manner Hellstrom and Tekle followed. For instance, a person is attractive if he scores five on the Likert scale thus if they were to take part in a beauty contest for men or women in their age bracket. In the study the researcher used a 7-point scale instead of the conventional 5-point scale for the provision of better variance in the results.
The researcher sampled 30 women from the total population. All the women sampled were to Continue reading...

Question 1: (Metallic Materials)

Recrystallization:
This is the process of growth of grain fragments in an alloy when it’s being worked on. This affects materials properties and services while in use.
Examples such as steel’s properties are affected such that there is reduction in strength and hardness of the material and this affects its applications and behavior in service. Other materials such as copper are affected in the same way.

Hot or cold working:

Hot or cold working involves hardening of materials and also and also heating the material. Iron is an example and is affected by hot working where it can be cast in Continue reading...

Is the Multiculturalism good or bad for women?

Abstract:
Multicultural world is what we have today. Nowadays, there is a huge wave of immigrants all over the world every year. Many women are integrating into the absolutely another culture, because of many reasons, in most cases, because of better work placements, higher education, high social worth of women's labor in law-full enfranchisement and activity for the wife, annulment of special criminal regulations affecting women, franchise for women. Big percent of those immigrants are political refugees. Countries that easily accept immigrants and have special immigration policies are becoming or already are multicultural.

They were pants that flare out from the knee with curved hems creating a circle from 18 to 26 inches around. While these pants were usually denim, they were seen in all colors and fabrics on both men and women. Sonny and Cher wore them; Lenny Kracitz and Elvis Presley did, too. They were bell bottoms.
Fashion changes as culture changes and when a culture is static, the styles of the young tend to imitate the clothing of the previous generation. But when social structure is in upheaval, fashion reflects the attitude of drifting from the excepted norm in Continue reading...

The term “chemical warfare” has many definitions, but they all essentially mean a type of military tactic that involves using chemical agents to incapacitate or kill the enemy 1. The use of chemicals such as phosgene, chlorine, and mustard gas in World War I initiated the use of a weapon not seen before on any battlefield 2. The toxins were used in addition to more traditional strategies involving hand-carried weapons, artillery, bombs, and so on. But the introduction of chemical warfare was an innovative method of removing men from the engagement; the topic of this paper is the use Continue reading...
