We disseminate the results of our research both to the scientific community through scholarly publications and to the public through exhibits, electronic media, and public lectures. We strive to maximize their availability to the scientific community, and we use specimens from these collections to best effect in our own research and exhibits. The Department of Mineral Sciences also offers postdoctoral and predoctoral fellowship opporunities. In the Division of Volcanology and Petrology, researchers study the entire solid planet, from the core to the crust, and try to understand the processes that have shaped our world.
The aim of this study was to investigate the effect of chromium on enzymatic activity of sorghum genotypes grown under polluted conditions.
Two weeks after sowing, seedlings of grown plants were irrigated with eight levels of chromium Cr VI concentrations 0, 2. Samples of plants were taken three times at 8th, 12th, and 15th days after chromium application to measure the enzymatic activity, namely, malate dehydrogenase, alcohol dehydrogenase and glutamate dehydrogenase.
The results revealed that the level of enzyme activity increased significantly with increase in chromium concentration.
Also the rate of increase in enzymatic activity, depend mainly on genotype and age of the plant. These findings suggest that, the activity of antioxidant enzymes of sorghum play a significant role in plant defense system.
Qazi, Raza Ur Rehman Abstract: In this study focus was on Personal Computer technology utilization. According to Davis, "A key purpose of TAM is to provide a basis for tracing the impact of external factors on internal beliefs, attitudes, and intentions" .
These two variables determine the usage and acceptance of a system . This study will test all the paths of original TAM, along with new factors perceived personal utility incorporated in the extended model developed by Dr.
Qazi, Raza Ur Rehman . Factors like organizational culture, individual factors including level of education and duration of training as external factors were also tested. Furthermore, in this study data are collected from employees both male and female who have used the Personal Computer technology at work for at least one year.
The results of this study indicated an overall positive association between all the constructs of the factors being tested except the association between the level of education and the actual computer use at job.
Similarly negative association was found between organizational culture and actual use of PC at job.

Rocks Research Paper At a granular level, rocks are composed of grains of minerals, which, in turn, are homogeneous solids formed from a chemical compound that is arranged in an orderly manner.
Feldspar — Feldspar is a rock-forming mineral. It is important industrially in making glass, ceramics, enamelware and soaps. It is also used in making bonding material for abrasive wheels, cements, fertilizer, tarred roofing materials and as a sizing or filler in textiles and paper.
