OBJECTIVE To investigate the relationship between the increase of body mass index and the prevalence and severity of asthma in adolescents from Santa Maria, in southern Brazil, and surrounding regions. METHOD A cross-sectional, observational, population-based study was carried out with 4,010 schoolchildren aged 13 and 14 years, without any gender restrictions, who answered the written questio...

The mean global increase in thermal radiation received at the surface of the earth as a consequence of a doubling of the atmospheric carbon dioxide content is calculated to be 2.28 watts per square meter. Multiplying this forcing function by the atmosphere's surface air temperature response function, which has recently been determined by three independent experimental analyses to have a mean gl...

BACKGROUND Vasodilators are considered to be contraindicated in patients with severe aortic stenosis because of concern that they may precipitate life-threatening hypotension. However, vasodilators such as nitroprusside may improve myocardial performance if peripheral vasoconstriction is contributing to afterload. METHODS We determined the response to intravenous nitroprusside in 25 patients ...

Semi-dwarf genes have been used to alleviate lodging and increase harvest index in barley. The present study was conducted determine the effect of widely sdw1.d allele on agronomic characters. transferred from cv. Triumph Tokak 157/37 using marker assisted backcross breeding, a near-isogenic line developed. Parents + near isogenic were evaluated three rainfed, fall-planted seven spring-planted ...

The research was carried out to determine the yield, yield components, quality, and stability of bread wheat (Triticum aestivum L.) genotypes in heat-stressed water-limited environments for two years. ANOVA GGE biplot analysis were applied differences relationships investigated traits belonging 10 different varieties. While grain (GY) is associated with thousand-grain weight (TGW) test (TW); pr...

The rapidly growing world energy use has already raised concerns over energy resources and greenhouse gas (GHG) emissions. Since the global contribution from residential buildings towards energy consumption, has steadily increased between 20% and 40% and as large openings have considerable energy and heat loss in dwellings, this paper establishes a coefficient of heat loss and air infiltration ...

Twenty hybrids were produced using five CMS lines viz., BRRI3A, BRRI9A, IR73328A, BRRI10A and IR78355A and four restorers viz., BRRI12R, BRRI13R, BRRI14R and BRRI15R following line x tester mating design to find out the best combination (s) in respect of their combining ability effects among the parents and hybrids at BRRI, Gazipur, Bangladesh from July 2008 to May 2009. Data were recorded from...
