A study at Dartmouth College of the English Wikipedia noted that, contrary to usual social expectations, anonymous editors were some of Wikipedia's most productive contributors of valid content.
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.
Detailed analysis is presented in the analysis section.The Scientific Revolution and the Enlightenment - (7) It was believed that God had created the universe for man, and that he had given the central position in his creation to man, giving people a profound sense of security however Copernicus theory took away man’s central position in the universe.
Overview of the Milliennium Ecosystem Assessment.
On this page: What is the Millennium Ecosystem Assessment (MA)? What are the main findings of the MA? Intro duction. Thomas Kuhn coined the modern definition of the word “paradigm” in The Structure of Scientific Revolutions, published in A paradigm, according to Kuhn's definition, is a conceptual model that explains a set of scientific observations, which creates a framework to fit the observations.

The detection of partial discharge by analyzing the components of SF6 gas in gas-insulated switchgears is important to the diagnosis and assessment of the operational state of power equipment. The contribution of different biofuels to reducing fossil-fuel consumption varies widely when the fossil energy used as an input in their production is also taken into account.
The fossil energy balance of a biofuel depends on factors such as feedstock characteristics, production location, agricultural practices and the source of energy used for the conversion process.
