Errors resulting from theseapproximations will be analyzed in this paper. This paper will show that these approximationsare not very accurate at all ranges of temperatures and pressures.

passage throughan atmospheric pressure argon plasma, operated at 1 kW or less power. Specifically, irregularlyshaped particles of gamma-alumina with an average diameter of 11 mu m were converted to smaller(ca. 4 mu m) spherical particles primarily consisting of delta- and alpha- (corundum) phases. Alsonotable was the finding that modifications of the particles, such as changes in surface area, correlateto applied plasma energy. The plasma torch was operated with an argon flow rate of 5 slpm, powerof between 400 and 1000 W, and average particle residence time in the plasma of 0.1 s.

terminology“multidisciplinary engineering programs” is defined as the set of engineering programs with oneof the following program titles (and a few slight variations): Engineering (including GeneralEngineering), Engineering Physics, and Engineering Science(s). An important characteristic thatthese programs have in common is that they do not have “program criteria” that supplement the“general criteria” that apply to the accreditation criteria for all other engineering programs. Thisnew role for ASEE means, among other things, that ASEE now has membership on the ABETEngineering Accreditation Commission (EAC) and is responsible for recruiting andrecommending Program Evaluators (PEVs) to ABET for accreditation visits for multidisciplinaryengineering

This project would benefit both small and large scalechicken farms by reducing cost of operation, manual labor, and increasing productivity. IntroductionBy the 1900’s, an average chicken farm was an extension of the family kitchen. Most ofthe chicken farms were usually owned and operated by families and had no automation.Very few sold poultry products. Chickens were used for the same purpose as they arenow which includes meat, eggs, and money.

There is little chance that this need in new electricity generation plantswill be satisfied.
