Geography and economics

The Ghana is an African country located on the western side of Africa. The neighbor countries are Burkina Faso, Togo, the Atlantic Ocean, and Cote d’Ivoire. It has a population of nearly 18,100, 703 and a population density may be of 197 people per square mile. The Ghana’s area is 92,098 square miles and the official language is English. The capital city is Accra has around 1, 673,000 residents. There are the physical statistics, which is to be considered.

The great strengths of the country are its natural resources. And also, they are very rich. The big export is Cocoa, which totally accounts for 15% of the world's supply. And also the gold production, now a days, it's exported as more as one million fine ounces. Ghana is also supplying bauxite, diamonds, coffee, rice, cassava, timber and rubber. After 1983, the economy has steadily grown. By the economic recovery policies intact, the economy has raised 5% a year since 1983. Tourism development also grows within Ghana. The Tourist rates are also increasing. With these cash crops, costly goods, and economic restructuring, one would wonder why they need assistance at all.

Infrared (IR) emission is electromagnetic emission of a wavelength longer than that of noticeable light, but shorter than that of radio waves. The name means "below red" (from the Latin infra, "below"), red being the color of detectable light of longest wavelength. Infrared radiation spans three instructions of magnitude and has wavelengths between about 750 nm and 1 mm.
These divisions are suitable by the different human response to this radiation: near infrared is the area closest in wavelength to the radiation detectable by the human eye, mid and far infrared are gradually further from the visible regime. Other definitions follow different physical mechanisms (emission peaks, vs. bands, water absorption) and the newest follow technical reasons (The common silicon detectors are sensitive to about 1,050 nm, while Inga As sensitivity starts around 950 nm and ends between 1,700 and 2,600 nm, depending on the specific configuration). Unfortunately the international standards for these specifications are not currently obtainable.
The boundary between visible and infrared light is not precisely defined. The human eye is markedly less responsive to light above 700 nm wavelength, so longer frequencies make irrelevant contributions to scenes illuminated by common light sources. But particularly strong light (e.g., from lasers, or from bright daylight with the visible light removed by colored gels [1]) can be detected up to approximately 780 nm, and will be apparent as red light. The onset of infrared is defined (according to different standards) at different values typically between 700 nm and 780 nm.

Affirmative Action

Affirmative Action: Mend it or End it
The act of hiring the minority groups in order to "balance out" the employment pool and therefore end discrimination in the workplace is called affirmative action. And too in many businesses and college campuses today use affirmative action to hire or accept new recruits based on affirmative action laws. This law causes people from the majority to lose to women and minority races, regardless of qualifications. This form of the reverse discrimination that makes distinctions based on race or gender is not beneficial to the American society whether it is constituted through a government law, program, or policy.
The Affirmative action has a contradiction with the policies it supports. Thus means that "the solution to the problem of racism and discrimination that affirmative action employs is more discrimination" Instead of curing racism in USA, the affirmative action promotes reverse discrimination by allowing minorities to feel as if they need standards to be lowered for them in order for opportunities to become available to them. The law is undervalued with the notion that "women are inherently weaker and less intelligent than white males because standards are lowered.
