PURPOSE This retrospective study was conducted to estimate the effects of climate factors and air pollution on asthma exacerbations using a case-crossover analysis. METHODS Patients who visited the emergency department (ED) of 2 university hospitals in Chuncheon for asthma exacerbations from January 1, 2006, to December 31, 2011, were enrolled. Daily average data for meteorological factors (t...

A Poisson regression between the observed climatology of tropical cyclogenesis (TCG) and largescale climate variables is used to construct a TCG index. The regression methodology is objective and provides a framework for the selection of the climate variables in the index. Broadly following earlier work, four climate variables appear in the index: low-level absolute vorticity, relative humidity...

temperature profile during the salting process play an important role in cheese quality since microbial and enzymatic activities, are thereby affected. in this work a three dimensional model was developed for heat transfer in the ultrafilterated cheese by using numerical solution of fourier's second law with finite difference method (explicit scheme) as a function of internal variable (che...

wheat (triticum aestivum) is one of the major crops in the world and iran. any plan for improvement of wheat yield requires sufficient information on different stages of crop life cycle and the effects of meteorological parameters. the purpose of this study was developing suitable regression models for prediction the length of pheonological stage of winter wheat in three different regions of ir...

abstract evapotranspiration as one of the important elements in agriculture has a considerable role in water resource management. therefore, using a more exact estimation method is an essential step of agricultural development, especially in arid semi-arid area. in this research, in order to exact estimate of garlic evapotranspiration using lysimeteric data, an artificial neural network (ann) m...
