The association between meteorologic temperature and sudden infant death syndrome was investigated in the 1982-1983 North Carolina birth cohort. Maximum daily temperatures recorded at weather stations in the subject's county of residence for each day of the first year of life were entered into hazards models as time-dependent covariates. Risk ratios for a maximum temperature of < or = 53 degree...

  To predict growth and yield, it is needed to study sub-models of phenology, dry matter production and partitioning, leaf area variations and soil water balance. In the present study, for predicting yield of maize under Isfahan conditions, parameters of the sub-models in the aforementioned model were estimated using data of planting dates between 1988 and 2004 in Isfahan region and data of oth...

net-screen covered greenhouses operating on natural ventilation are used as a sustainable approach for closed-field cultivation of fruits and vegetables and to eliminate insect passage and the subsequent production damage. the objective of this work was to develop a real-time assessment framework for evaluating air-temperature inside an insect-proof net-screen greenhouse in tropical lowlands of...

Introduction According to geographical location of Iran and relatively high elevation of most of its areas above sea-level, occurrence of frosts has many negative effects on different sections, such as agricultural, transportation and energy. Frosts are generally related to displacement and movement of cold anticyclones from northern latitudes to Iran. Wide range of synoptic characteristics is...
