an Red-wood" in English, and as " Rohun" in the Vernacular. It is common in Central India. The wood is of a red colour, strong, heavy and durable and well adapted for building purposes and for making articles of furniture ; it is not readily attacked by white ants. The bark, according to Ainslie, is "of a dingy red colour, and has a pleasant bitter taste, with a slight degree of austerity." (A ...

Associations between root diseases and bark beetles (Scolytidae) constitute some of the most serious pest complexes affecting forests in North America and elsewhere. The interactive functioning of these pests derives from the following relationships: 1) root diseases predispose trees to bark beetle infestation by lowering resistance, and perhaps increasing attractiveness, of trees to the attack...

Cordia rothii Roem. & Schult. bark has reputation of being effective in heart ailments in Saurashtra region of Gujarat. The investigation was undertaken to study the microscopy, chemical constituents and pharmacological actions of Cordia rothii Roem. & Schult. bark. Phytochemical analysis of different bark extracts revealed the presence of alkaloids, glycoalkaloids, coumarins and inorganic salt...

Extracts of S. asoca bark and pure compounds isolated from the bark were tested for properties that might inhibit the conversion of arachidonic acid by the PGH2 synthetase. They were assayed spectrophotometrically with adrenaline as cofactor. Methanol- and ethyl acetate extracts inhibited the conversion. The observed inhibition was confirmed in an oxygraphic assay. Two procyanidin dimers from t...

Commercially available controls for reducing worker exposure to paint overspray were evaluated in six autobody shops and a spray-painting equipment manufacturer's test facility. Engineering control measures included spray-painting booths, vehicle preparation stations, and spray-painting guns. The controls were evaluated by measuring particulate overspray concentrations in the worker's breathing...

Droplet transport processes that occur in fuel sprays and spray flames were examined using laser velocimetry, phase Doppler interferometry, and laser sheet beam photography. Droplet size and velocity (axial and radial) distributions were obtained in a swirl-stabilized, pressure-atomized kerosene spray under nonburning and burning conditions. The results show that the introduction of swirl to th...

Charged particulate spray systems are common in many industrial and manufacturing processes. Using externally applied electromagnetic fields – the dynamics of these particulate sprays can be altered to achieve improved functionality and access to spray-sites that are hard to reach. With such an alteration the spray-particulate dynamics can become non-intuitive – thereby motivating a physically ...

A cross-sectional study was conducted in 25 spray painters and 35 control subjects to evaluate neurobehavioral function, and thyroid and reproductive hormones profile. This study indicated higher prevalence of psychological and neurological symptoms, and clinical findings among spray painters when compared with controls. Levels of TSH were significantly (p<0.01) elevated in spray painters over ...

There are many ways to reduce diesel engine exhaust emissions. However, NOx emission is difficult to reduce because the hydrocarbon (HC) concentration in a diesel engine is not sufficient for NOx conversion. Therefore, in order to create stoichiometric conditions in the De-NOx catalyst, a secondary injection system is designed to inject liquid HC into the exhaust pipe. The atomization and distr...

arterial blood gas (abg) sampling is a painful procedure with no perfect technique for quelling the discomfort. an ideal local anesthesia should be rapid, easy to learn, inexpensive, and noninvasive. this study was aimed to compare pain levels from abg sampling performed with vapocoolant spray in comparison to placebo. we hypothesized that pretreatment with the vapocoolant would reduce the pain...
