the   stembark of mammea africana is used traditionally for the treatment of stomach pains. the present study was designed to evaluate the effects of ethanolic stembark extract of mammea africana on experimentally induced diarrhoea and ulcer . the extract ( 30 – 90mg/kg) was administered orally in rats 30 minutes to one hour before the induction of diarrhoeal and ulcer using different experimen...

a field experiment was conducted during 2009-2011 at the aligarh muslim university agricultural research farm, india, to evaluate the efficacious nature of some oil-seed cakes such as neem cake and castor cake, a botanical calotropis procera and phosphate solubilizing bacteria (psb) pseudomonas fluorescens singly and in various combinations, on the growth and productivity of trigonella plant. g...

CASTOR (the CERN Advanced STORage system) is used to store the custodial copy of all of the physics data collected from the CERN experiments, both past and present. CASTOR is a hierarchical storage management system that has a disk-based front-end and a tape-based back-end. The software responsible for controlling the tape back-end has been redesigned and redeveloped over the last year and was ...

Three DNA buoyant density species (nuclear, 1.692 g cm(-3); mitochondria 1.705 g cm(-3); and proplastid, 1.713 g cm(-3)) can be detected in extracts from castor bean endosperm. No other buoyant density species can be identified. DNA extracts from sucrose density gradient purified glyoxysomes exhibit varying amounts of each of the three identified DNAs but no other distinguishable DNA species. R...

Silver nanoparticles were fabricated by ablation of a pure silver plate immersed in castor oil. A Nd:YAG-pulsed Q-switch laser with 1064-nm wavelength and 10-Hz frequency was used to ablate the plate for 10 minutes. The sample was characterized by ultraviolet-visible, atomic absorption, Fourier transform-infrared spectroscopies, and transmission electron microscopy. The results of the fabricate...

this study was carried out to determine the effect of seed growing regions and loading speed on some mechanical properties of castor seed. these properties are used to design and improve related machines such as expeller that are used for extraction of oil from castor seed. mechanical properties of castor seed were expressed in terms of rupture force and energy, bio-yield force, apparent modulu...

The purpose of this study was to determine if continued monitoring and removal of beavers {Castor canadensis) from previously controlled beaver damage sites resulted in less additional damage than not monitoring such sites. Beavers were removed from 34 sites in nine southeast Texas counties from August 1996 through March 1997. Sixteen sites subsequently were monitored monthly and, if beavers ha...

We developed nine new nuclear dinucleotide microsatellite loci for Castor canadensis. All loci were polymorphic, except for one. The number of alleles ranged from two to four and from five to 12 in populations from Arizona and Wisconsin, respectively. Average heterozygosity ranged from 0.13 to 0.86 per locus. Since cross-species amplification in Castor fiber was successful only in four loci, we...
