The optimal planning of condition-based maintenance strategy based on the degradation process is of great concerned in the past few years. A lifetime delayed degradation process with heterogenous degr...
Accelerated Degradation Testing (ADT) provides an efficient experimental approach to collect lifetime-related data for the reliability assessment of highly reliable products under normal use stress. R...
The totality of RNA molecules in an organism at any one time is the product of a delicate dance. Genes must be “turned on,” or expressed, in order to turn DNA into RNA and then that RNA into proteins ...
Poly(β-hydroxyalkanoates), PHAs, are thermoplastic polyesters, which have potential for use as biodegradable plastics. The material properties of PHAs depend upon their chemical structure. Pseudomonas...
Microbes, traditionally characterized by their capacity to decompose cellulose anaerobically, were examined for the ability to degrade the chemically-related polymer, chitin. Our results suggest that ...
This research examined the environmental fate of two polycyclic aromatic hydrocarbons (PAHs), naphthalene and phenanthrene, under in situ, sulfate-reducing conditions, and the composition of the micro...
Actinomycetes have been used with enormous success in industrial processes; however, little is known about biofilm development by these filamentous microbes, and the presence of community development ...
The Veleta cirque is located at the foot of the Veleta peak, one of the highest summits of the Sierra Nevada National Park (southern Spain). This cirque was the source of a glacier valley during the Q...
Genomic analysis and physiological experiments conducted on the lignocellulosic biomass degrading bacterium C. phytofermentans, indicates that it can degrade and utilize a wide-range of carbohydrates ...
Immature or incompletely assembled proteins that do not fold correctly are retained in the endoplasmic reticulum (ER) by quality control factors. Terminally misfolded glycoproteins are eventually sort...
Protein degradation by ATP dependent proteases is a universally conserved process. Recognition of substrates by such proteases commonly occurs via direct interaction or with the aid of a regulatory ad...
This experiment was performed to investigate the effects of exogenous xylanase supplementation on performance, nutrient digestibility and the degradation of non-starch polysaccharides (NSP) in differe...
An in vitro fermentation was conducted to determine the effects of hainanmycin on protein degradation and populations of ammonia-producing bacteria. The substrates (DM basis) for in vitro fermentation...
A series of in vitro studies were carried out to determine i) the effects of enzyme and formaldehyde treatment on the degradation characteristics of carbohydrate and protein sources and on the synchro...
In many respects, river basins are extremely convenient natural resources management units and hence calls for an integrated approach in case of transboundary nature. Environmental resources in Kagera...
