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...

Schools are working to improve achievement through the examination of instructional practice and the use of instructional technology. This article provides informed commentary on the state of school reform and the need for continuous improvement, instructional improvement and instructional technology improvement. It also presents advocacy for the use of a continuous improvement system called le...

Under the Clinical Laboratory Improvement Act of 1967 the Health Care Financing Administration's proficiency-testing requirement applies to approximately 12,000 hospital, reference, and large-clinic laboratories in the United States. The Wisconsin State Laboratory of Hygiene is approved by the Health Care Financing Administration to provide proficiency testing in all specialties and subspecialt...

Traditional quality-control methods are effective for detecting systematic error caused by deterioration of reagents or instruments, but ineffective for detecting sporadic error, which is more likely to occur in low-volume testing environments. Decentralized testing performed by individuals without formal laboratory training has a high potential for sporadic errors. New methods for validating t...

Drastic genetic changes have occurred in many commercial broiler lines during the last years with regard to performance. This genetic improvement needs a corresponding adjustment of our knowledge about amino acid nutrition in broilers. Additionally, today broiler feed formulators are not only focused on minimising the costs. They also have to take into consideration environmental issues and the...
