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

| | | An Overview: Conflict is inevitable among humans. When two or more social entities (i.e.‚ individuals‚ groups‚ organizations‚ and nations) come in contact with one another in attaining their objectives‚ their relationships may become incompatible or inconsistent. Relationships among such entities may become inconsistent when two or more of them desire a similar resource that is in short

Physics assignment Aim To determine which 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

Examine the role of one human activity in causing climate change The earth is becoming hotter as the world is becoming more developing. Climate does change from time to time‚ but human activity increases the frequency and devastation of the change. This essay will concentrate on how industrialization contributes to the increased production of greenhouse gases and discuss how this in turn influences climate change. Since the industrialization becomes worldwide‚ every country tries to find its way

Children that have been met with this adversity can all too often feel unloved‚ unworthy‚ insecure‚ rejection‚ have very low self-esteem and a lack of trust in the adult world. (Lowenthal‚ 1999). Caregivers can provide these young children with the care‚ stability and nurturance they need to recover from such events

He favored resistance through the mind mostly‚ writing his first work called A Narrative of the Life of Frederick Douglass‚ an American Slave in the year 1853‚ which would only contribute to his fight against slavery in the Americas. Frederick Douglass wrote about the treatment of slaves and himself in his narrative. As a result of studying
