Nutrient loading into rivers is generally increased by human-induced land-use changes and can lead to increased surface water pollution. Understanding the extent to which land-use patterns influence nutrient loading is critical to the development of best-management practices aimed at water-quality improvement. In this study, we investigated total nitrogen (total N) concentration as a function o...

Driven by rising income and urban population growth, China has experienced rapid urban expansion since the 1980s. Urbanization can have positive effects on the urban environment; however, improvement of urban environment quality, especially its divergence between relatively developed and undeveloped cities in China, is currently a rather rudimentary and subjective issue. This study analyzed urb...

Enzymes are one of the most important biomolecules which has a wide range of applications in industrial as well as biomedical field. They are important due to their many useful properties. Their development, to a great extent, has been possible due to the availability of microbial sources. Microorganisms are of much attention because they can be produced economically and are amenable to genetic...

At the last Pig Genetics Workshop two papers described aspects of the lost potential in pig production at the commercial level. Black (2000) estimated that slower growth, reduced efficiency of feed use and fatter carcases decreased the profitability of pig enterprises by as much as 25%. Walters (2000) estimated that successful progress had been achieved in backfat reduction but that there were ...
