Debaryomyces hanseniZopf isolated from the fructoplane of apples were found to be effective as biocontrol agent against rot of papaya caused by Ulocladium. chartarum(Pr.) Simm. The ability of D. hansenii to prevent infection of U. chartarum was lost when the antagonist cells were killed by autoclaving. Cell free culture filtrates of antagonist were unable to prevent disease incidence. Efficacy ...

To the Editor, The Indian Medical Gazette. Sir,?Dr. Brahmachari advises the use of sodium chloride in making up antimony solutions for injection, ' and Drs. Napier and Muir state that the use of sodium chloride does not matter much and their injections can be given without sodium chloride. I have recently noticed in my kala-azar centres that while using scale preparation of sodium antimony tart...

The enhancing effect of sodium chloride addition on the adsorption of paraquat onto activated carbon was discussed from the standpoints of equilibrium amount adsorbed and adsorption rate in vitro. The amount of paraquat adsorbed was increased by the addition of sodium chloride. The amount adsorbed with 0.1% addition was about five times greater than that in sodium chloride-free solution at an e...

The rates of oxidation of Fe(II) by H(2)O(2) in the presence of sodium perchlorate, sodium nitrate, sodium chloride and sodium sulfate salts (0-1M) have been compared in the study. Experiments were carried out in a batch reactor, in the dark, at pH <3, 25+/-0.5 degrees C and at controlled ionic strength (< or =1M). The experimental results showed that the rates of oxidation of Fe(II) in the pre...

Irrigating wounds with tap water does not increase colonisation, but controlled studies are required for further evidence. Microbial colonisation was assessed in skin wounds, before and after irrigation with tap water, and was compared with irrigation using 0·9% sodium chloride sterile solution. The study included 120 subjects with chronic, traumatic, vascular, pressure or neuropathic wounds. A...

We study the Lax-Friedrichs scheme, approximating the scalar, genuinely nonlinear conservation law u, + fx(u) = 0, where /(h) is, say, strictly convex, /> ¿„ > 0. We show that the divided differences of the numerical solution at time t do not exceed 2(/¿,)-1. This one-sided Lipschitz boundedness is in complete agreement with the corresponding estimate one has in the differential case; in partic...

abstract various resistances to salinity are due to plants genetically variations, and selection on the basis of one factor will not be a suitable criterion in measurement of resistance to salinity, therefore in choosing resistant varieties, it is necessary to notice to a set of resistant indexes to salinity, creating changes in physiology, anatomy and morphology of plant species. this research...

Microbial fuel cell represents an emerging technology to attain electrical energy from wastewater. There are several alternative methods available for wastewater treatment; Microbial fuel cell is one of them, which generates green energy from wastewater for making a contribution to renewable sources of energy. This study states the performance of microbial fuel cell with different parameters i....

We used in vivo perfusion of the lower intestine (colon plus coprodeum) to examine the osmoregulatory role of that organ in glaucous-winged gulls (Larus glaucescens Naum.) drinking sea water and fresh water. The area of the lower intestine was small, 0-59 cm 100g~' body mass. Its electrolyte and water transport rates were unaffected by salt water acclimation. Sodium and chloride were always rea...
