This paper provides a specific application of the Environmental Kuznets curve is a hypothetical relationship between various indicators of environmental degradation and income per capita. In the early stages of economic growth degradation and pollution increases, but beyond some level of income per capita it tends to reverse, so that at high economic growth leads to environmental improvement. T...
Microbial cellulases find applications in various industries and constitute a major group of the industrial enzymes. Recently, there is resurgence in utilization of biomass for fuel production employing cellulases and hence forth in obtaining better yields and novel activities. Improving the economics of such processes will involve cost reduction in cellulase production which may be achieved by...
The aim of this project was to optimise selection indices for efficient lean meat growth. Traditionally, genetic improvement of lean meat growth and feed efficiency has been based on ad libitum feeding. However, selection for lean meat growth and feed conversion ratio under ad libitum feeding has led to a reduction in feed intake in modern genotypes to the extent that feed intake is often not s...
Chemiluminescent immunoassay (CLIA) has been applied in different fields, including environmental monitoring, clinical diagnosis, food safety and pharmaceutical analysis, as a promising approach for selective, sensitive, rapid and simple analysis. It is often necessary to detect a large number of complicated or low-abundance samples. However, traditional methods need great consumption of time, ...
Pig breeders have successfully selected for higher litter size, reduced backfat and improved growth rate (Hermesch, 2006). These outcomes imply that modern sows have higher nutrient demands in comparison to sows of 20 years ago. For example, genetic improvement of litter size has been 0.10 to 0.20 piglets per year in maternal lines. This implies that sows need to eat 50 to 100 grams more feed p...
