SUMMARY IE-Kb (Intron Exon-Knowledge base) illustrates the intron-exon dynamics in eukaryotic genes. We have developed three different knowledge sets, namely 'Non-redundant ExInt', 'Non-redundant Pfam-ExInt complement' and 'Non-redundant GenBank eukaryotic subdivisional sets' to understand this phenomenon. Statistical analysis is performed on each knowledge set and the results are made availabl...

We propose a theory for axial segregation of suspensions of non-neutrally buoyant particles in a rotating cylinder. The cylinder is oriented in the horizontal plane, so that any axial forces must arise from interparticle interactions. We show that the hydrodynamic interaction between pairs of particles produces a relative motion in the axial direction, independent of the gravitational force. If...

Abstract Rainfall-induced slope instabilities are ubiquitous in nature, but simulation of this type hazards with centrifuge modelling still poses difficulties. In paper, we introduce a rainfall device for initiating failure medium-sized centrifuge. This system is simple, robust and affordable. An array perforated hoses placed close above the model surface to generate raindrops. The intensity de...

dans cet article, l'auteur tudie la creation d'une voie ferre interurbaine, de la banlieue ou urbaine, et essaie de d6terminer le nombre optimal de stations pour une longueur donnee de la ligne; compte tenue d'une repartion du trafic, ie long de la ligne en question qui est suppose etre connue. le critere d'optimalisation est le temps total perdu par l'ensemble des usag...

dans cet article i' intervalle entre deux trains successifs a ete etudie en fonction de leur vitesses dans deux cas differents. dans ie premier cas ,on suppose que la vitesse des deux trains a une valeur constante, et on etudie les variations de l'intervalle minimum en fonction de la vitesse on determine la vitesse optimale et on etudie les variations de l'intervalle minimum en f...

The research method is included Quasi Experimental Design form Nonequivalent Control Group Design. Based on results testing hypothesis post-test data for experimental control classes calculation t test In...

background: molecules expressed on the surface of infected erythrocytes (ie) with plasmodium falci-parum play important roles in malaria pathogenesis and immune evasion. some of these molecules are specific adhesive ligands mediating adhesion of ie to the vascular endothelium. in the current study, the antigens exposed on the surface of ie with different isolates and various binding subpopulati...

BACKGROUND Consensus on whether physical condition affects the risk of gravity-induced loss of consciousness (G-LOC) has not been reached, and most previous studies about the issue did not include well-experienced aviators. We compared the physical conditions of well-experienced young aviators according to the occurrence of G-LOC during human centrifuge training. METHODS Among 361 young male ...

Internally cured (IC) concrete is frequently produced in North America using pre-wetted lightweight aggregate (LWA). One important aspect associated with the production of quality IC concrete is the accurate determination of the moisture content, including absorbed moisture and surface moisture of the LWA. Knowledge of the moisture content enables aggregate moisture corrections to be made for t...

Porous silicon (PSi) is an innovative inorganic material that has been recently developed for various drug delivery systems. For example, hydrophilic and hydrophobic PSi microparticles have been utilized to improve the dissolution rate of poorly soluble drugs and to sustain peptide delivery. Previously, the well-plate method has been demonstrated to be a suitable in vitro dissolution method for...
