OBJECTIVE To assess health-related quality of life in sugarcane cutters. METHODS Longitudinal study conducted in a sugar and ethanol plant located in the western region of the State of São Paulo (Southeastern Brazil) from April (pre-harvest) to October (harvest) 2010. A total of 44 sugarcane cutters, smokers and non-smokers, was evaluated in three periods: pre-harvest, at the end of the third...

OBJECTIVE Evaluate the impact of stress on sugar cane cutters and the prevalence of physical and psychological symptoms before and after harvest. METHODS We studied 114 sugarcane cutters and 109 urban workers in the pre-harvest and 102 sugar cane cutters and 81 urban workers in the post-harvest period in the city of Mendonça, SP, Southeastern Brazil, in 2009. Data analysis was based on the fr...

—Since European colonization and subsequent commercialization of Appalachian medicinal and edible plants, millions of kilograms of plant material have been extracted from our forests, with little effort to manage these species as natural resources. Roots and rhizomes of black cohosh, a native Appalachian forest herb, are extensively harvested for treatment of menopausal symptoms. As nearly all ...

Forest harvest alters natural nutrient cycles, which is reflected in stream water run-off from harvested catchments. Nitrate is an essential nutrient for plant growth, but increased concentrations in rivers, lakes, and oceans have contributed to eutrophication and anoxic conditions. Based on a literature review, we assessed the impact of three different harvest methods—clearcut, patchcut, and s...

Knowledge about recruitment in a population can be critical when making conservation decisions, particularly for harvested species. Harvest can affect population demography in complex ways and this may be particularly true for cooperatively breeding species whose successful reproduction is often linked with complex social dynamics. We currently have a poor understanding of how harvest affects r...

In this research the exclusive decay of                         is calculated by QCD factorization (QCDF) method and final state interaction (FSI). First, the  decay is calculated via QCDF method. The result that is found by using the QCDF method is less than the experimental result. So FSI is considered to solve the decay. For this decay, via the exchange of mesons are chosen for the intermedi...
