effectiveness of furfural as an organic inhibitor in 5 percent hydrochloric acid which is used in acid pickling of steel was evaluated. lungmuir, frumkin and flory-huggins isotherms [1, 2] were used to determine the parameters of effective adsorption, free energy and entropy of adsorption. furfural indicated an inhibition less than 17 percent in concentrations of 0.001 mole per liter for a dura...

BACKGROUND Betaine, beetroot juice, and supplemental nitrate have recently been reported to improve certain aspects of exercise performance, which may be mechanistically linked to increased nitric oxide. The purpose of the present study was to investigate the effect of betaine supplementation on plasma nitrate/nitrite, a surrogate marker or nitric oxide, in exercise-trained men. METHODS We us...

Copyright © 2006 Massachusetts Medical Society. A 53-year-old woman with asthma and multilobar pneumonia is admitted with respiratory failure. She is intubated and treated with antibiotics, albuterol, and methylprednisolone. A random blood glucose measurement obtained on admission shows a level of 183 mg per deciliter (10.2 mmol per liter). After 3 hours in the intensive care unit, she has a ca...

Apparently large exposures of the general public to the radioactive decay products of radon-222 present in indoor air have led to systematical appraisal of monitoring data from U.S. single-family homes; several ways of aggregating data were used that take into account differences in sample selection and season of measurements. The resulting distribution of annual-average radon-222 concentration...

Ten metabolites of Fusarium species (butenolide, diacetoxyscirpenol, equisetin, fusaric acid, gibberellic acid, moniliformin, NRRL 6227 peptide, T-2 toxin, vomitoxin, and zearalenone) were added to the drinking water of mice to determine whether they were consumed or refused. Of the 10, only the trichothecenes--diacetoxyscirpenol, T-2 toxin, and vomitoxin--were refused. Refusal of 2 mg of the t...

The amount of extracellular polysaccharide produced by eight species of green and blue-green algae ranges from 174 milligrams per liter to 557 milligrams per liter. Most of the polymers are composed of four monosaccharides: a hexose, a pentose, a methyl pentose, and uronic acid. The production of excessive amounts of these photosynthetic end products will undoubtedly influence the effective rec...
