Molecular analysis of bacterial community dynamics during bioaugmentation studies in a soil column and at a field test site

Creator:

Li, Jun

Abstract:

1,1,1-Tricholorethane (1,1,1-TCA), a widely used industrial solvents, is one of the most common subsurface contaminants. Transformation processes in the subsurface can result in the production of 1,1-dichioroethane (1,1-DCA) and 1,1- dichioroethene (l,1-DCE) from 1,1,1-TCA contamination, resulting in plumes of mixed chlorinated aliphatic hydrocarbons (CAHs). A butane-utilizing microorganism, strain 1 83BP,...

Preparing sustained release dosage forms of nifedipine by hot-melt coating method

Creator:

Le, Hang Thi

Abstract:

A nifedipine sustained release dosage form was prepared by using hot-melt batch coating. Substrates are sugar beads, mesh size 30-35. Stearic acid, Acid Triglyceride, and carnauba wax were coating agents used to make single layer coated beads and multiple layer coated beads containing nifedipine. Dissolution of nifedipine from the beads...

New configurations of bandpass filters in single and multilayer environment

Creator:

Gururajan, Kala

Abstract:

Mobile and telecommunication industry has experienced tremendous growth in the recent past. Miniaturization and increased functionality have become necessary for all passive components in the system. Bandpass filters are critical passive components in any communication system and the existing designs in the crucial 1-10 GHz bandwidth suffer many drawbacks. For...
