slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. maximum glucose yield ...

long term monitoring programme on brine shrimp ( artemia sp.) is being carried out by the environment agency, abu dhabi, united arab emirates (ead) with the prime purpose of understanding the population dynamics, ecology and habitat requirements of artemia at al wathba lake, situated within al wathba wetland reserve, which is an artificial wetland near abu dhabi city. the present study, being a...

Interactions between proteins are orchestrated in a precise and time-dependent manner, underlying cellular function. The binding affinity, defined as the strength of these interactions, is translated into physico-chemical terms in the dissociation constant (K(d)), the latter being an experimental measure that determines whether an interaction will be formed in solution or not. Predicting bindin...

Membrane proteins play important roles in the biological process and accurate discrimination of membrane proteins from non-membrane proteins/globular ones would help to locate them in the genome sequences. However, the structural biology of membrane protein is limited due to the physiochemical complexities in determining its three dimensional structures. Thus the requirement of predicting membr...

Intrinsic disorder (ID) is a widespread phenomenon found especially in signaling and regulation-related eukaryotic proteins. The functional importance of flexible disordered regions often resides in their ability to allow proteins to bind different partners. The incidence and location of intrinsic disorder in 369 human single-pass transmembrane receptors with the type I topology was assessed ba...

A multivariate analysis method called co-inertia analysis was used to determine the main relationships between two data tables having identical rows. This method is available in the ADE multivariate analysis package for Macintosh micro-computers. It was applied to two data sets, one containing the amino-acid composition of 999 E. coli proteins, and the other the values of 402 physico-chemical p...
