Contributions of ammonia-oxidizing bacteria and archaea to nitrification in forest soils

Creator:

Lu, Xinda

Abstract:

Prior to 2005, ammonia oxidation, the first step of nitrification, was thought mediated mainly by ammonia-oxidizing bacteria (AOB). However, the discovery of Thaumarchaeota carrying the genes coding for the ammonia monooxygenase (AMO) enzyme led to the discovery that ammonia-oxidizing archaea (AOA) also contribute to nitrification. Despite the uptick in studies...

Relationship of inbreeding to heterosis in swine

Creator:

Liu, Lillian Ling-Ling

Abstract:

Records of 889 litters of three populations of swine farrowed between 1962 and 1973 were analyzed by least squares procedures. Estimates were obtained for the effects of age and inbreeding of dam, inbreeding of litter, inbreeding of dam's dam and inbreeding of the sire of the litter on litter size...

Friction losses for water flowing in non-circular ducts

Creator:

Mohandes, Abdolhosein

Abstract:

Friction factors were measured for water flowing in ducts made up of two rods held between two flat plates. Three rod diameters of 0.50, 1.00 and 1.50 inches were used. The spacings between rods varied from 0.0 to 0.32 inch. It was found that the concept of hydraulic diameter was...

ASIC for real time data authentication

Creator:

Anjum, Vaseem

Abstract:

Authentication is a means of developing an electronic signature that works like a written signature. It assumes that your data is publicly known but nevertheless ensures that the message is not tampered with and that you have an audit trail. This project discusses the techniques and concepts used to design...
