The objective of this study was to determine the prevalence of common mental disorders and the association with social support in a community located in the Zona da Mata, a sugar cane plantation area in the State of Pernambuco, Brazil. A household survey was carried out and the Self-Reporting Questionnaire (SRQ-20), the Medical Outcomes Study, and socioeconomic questions were administered to al...

Coarse Particles and Dust Storm Mortality In a paper titled "Episodes of High Coarse Partide Concentrations Are Not Associated with Increased Mortality," Schwartz et al. (1) concluded that "coarse particles from windblown dust are not associated with mortality risk." The authors seem to have overlooked the medical literature on the health effects of the historic U.S. dust storms of the dust bow...

Uptake of sucrose and hexoses by cotton (Gossypium hirsutum L.) hypocotyl segments from free space was shown to be an active, carrier-mediated process. Separate carriers existed for hexoses and sucrose. Accumulated sugars appeared in both soluble and insoluble fractions of the tissue. At optimum temperature and pH, sucrose uptake rate versus concentration was fit by a rectangular hyperbola with...

We show that strictly abnormal geodesics arise in graded nilpotent Lie groups. We construct such a group, for which some Carnot geodesics are strictly abnormal and, in fact, not normal in any subgroup. In the 2-step case we also prove that these geodesics are always smooth. Our main technique is based on the equations for the normal and abnormal curves, that we derive (for any Lie group) explic...

introduction crop productivity is highly constrained by water and nitrogen limitations in many areas of the world (kalra et al., 2007). therefore, there is a need to investigate more on nitrogen and water management to achieve higher production as well as quality. irrigated sugar beet in the cropping systems of khorasan province in northeastern of iran accounts for about 34% of the land area un...

background: diabetes is the most common metabolic disorder which is required to be taken under control. according to some studies, the impact of self-regulation on health has been considered as a monitoring strategy to achieve individual’s goals. objectives: this study, which was performed in 2012, aimed at determining the consequences of self-regulation on controlling type 2 diabetes. patients...
