Esophageal cancer (EC) is one of the most common cancers in China. The purpose this study was to investigate updated incidence rates and risk factors EC Nan'ao Island, where rate chronically highest southern To calculate annual rate, data on 338 cases from Cancer Registry system diagnosed during 2005-2011 were collected. A case-control conducted explore factors. One hundred twenty-five alive patients 250 controls enrolled into study. pre-test questionnaire demography, dietary factors,...
As urban areas experience economic growth and expansion, the development scale intensity of commercial complexes have notably increased. Integrating aboveground underground spaces enhances vitality latter, thereby improving land efficiency. However, these encounter challenges, including disconnections in design, leading to poor continuity suboptimal outcomes. Existing research predominantly discusses individual factors influencing space integration, lacking a comprehensive assessment...
Biomass waste in agricultural and forestry production has low value, large volume, disordered texture, high water content, recycling costs, disturbing its biomass treatment. In terms of mainstream treatment methods, incineration directly releases carbon dioxide, dust, other pollutants, while landfills produce dioxide methane with stronger greenhouse effects. response to this problem—taking pollution reduction, sequestration, the resource utilization as purpose—a mode in-situ, harmlessness,...
In this study, we determine the associated number of zeros for Abelian integrals in four classes quadratic reversible centers genus one.
