ABSTRACT COOKSON‚ EDWARD JAMES. Development of the Metal Foam Electrical Resistance Heater. (Under the Direction of Dr. Albert Shih.) This thesis presents a novel concept using a radial heating element made from porous Fe-Cr-Al metal foam in an air heater. Electrical resistance heating has been used extensively to convert the electrical energy into thermal energy. An analytic heat transfer model is first developed to estimate dimensions of the heating element. Four prototype Fe-Cr-Al metal

Gang Resistance Education and Training Gang Resistance Education and Training (G.R.E.A.T) is a national program that educates elementary and middle school children how to avoid becoming a gang member. The program is instructed by police officers and is part classroom instruction and other learning activities. “The goal of the GREAT program is to teach youth how to set goals for themselves‚ how to resist peer pressure‚ how to resolve conflicts‚ and how gangs can affect the quality of their lives

What is peaceful resistance? We have seen many examples in history up even to today‚ in my case‚ even close to home. Peaceful resistance and non-violent protests is the practice of achieving goals through symbolic protests‚ civil disobedience‚ and noncooperation. The real question is with deaths of many great leaders and people throughout history with this "peaceful protest" is it a good thing? If you look at the outcomes‚ the positives outweigh the negatives. If colonial Indians hadn’t spoken-out

Task To investigate how the resistance of a wire is affected by the length of the wire. Theory What is resistance? Resistance is a force which opposes the flow of an electric current around a circuit so that energy is required to push the charged particles around the circuit. The circuit itself can resist the flow of particles if the wires are either very thin or very long. e.g. The filament across an electric light bulb. How is it measured? The resistance of a length of wire is calculated

factors affect the resistance of a conductor‚ and the mathematical relationship that exists between these variables. Hypothesis Copper wires would be a better conductor than nichrome wires because it would yield less resistance when they have same cross-sectional area‚ length and temperature. Resistance would be increased when length wires increased. Resistance would be increased when cross-sectional area of wires decreased. Resistivity of wires is a factor of affecting the resistance.

Consequently‚ victims of this ugly facet of human nature are left to decide between two main methods of response: violent retaliation or amicable appeals to the government. Aggression is at times viewed as a

Their organization has defined oppression as confining minorities to the lower limit and outer edge in political‚ social‚ and economic aspects of life (Martin). The first strategy of resistance their organization should try to incorporate is education. Lawrence Blum‚ a philosophical writer for racial resistance‚ highlights three big points in his essay "Three Educational Values For a Multicultural Society." He states that the problems in our society can only be overcome by first educating our

There are many tactics to get a point across. Some will use violent ways and others will choose to do peaceful resistance. Peaceful resistance positively impacts a free society.

There were many resistances from slaves‚ violent and non-violent‚ during the period of slavery in the BWI. Violent resistance was in the form of revolts and rebellions and non-violent resistance included actions such as suicide‚ poisoning‚ avoiding work and maroonage. However‚ there were three violent resistances which stood out. These three were Bussa Rebellion in Barbados (Easter 1816)‚ Demerara Revolt in Guyana (August 1823) and the Sam Sharp Rebellion in Jamaica (December 1831). These rebellious

British indirect rule. The British would take steps to prevent this from happening. Methods Africans used to protest Colonial rule during the first decades of the 20th century included a religious opposition‚ a radical confrontation‚ and a political resistance. The religious opposition to colonial regulation was focused around the Watchtower Movement in Central Africa. At the turn of the 20th century‚ a hut tax was being imposed in Zambia by the British which increased Africans’ feeling of animosity
