Knowledge of when critical crop stages occur and how the environment affects them should provide useful information for crop management decisions and crop production models. This research evaluated two sources of data for predicting dates of silking and physiological maturityof corn (Zea mays L.). Initial evaluations were conducted using data of an adapted corn hybrid grown on a Typic Agriaquol...

This study analyses potential associations between day-to-day variations in common ragweed pollen counts in the southern Hungarian district of Szeged and meteorological variables using adapted factor analysis. The database includes ten years (1997-2006) worth of data on daily common ragweed pollen ratios (value on the given day per value on the day before) and daily differences (value on the gi...

Moniliophthora Pod Rot (MPR) caused by the fungus Moniliophthora roreri (Cif.) Evans et al., is one of the main limiting factors of cocoa production in Latin America. Currently insufficient information on the biology and epidemiology of the pathogen limits the development of efficient management options to control MPR. This research aims to elucidate MPR development through the following daily ...

abstract introduction: heat stress risk assessment, as a harmful agent at workplace, is essential for controlling heat strain and heat stress effectively. this study is concerned with the relationship between physiological strain index (psi) and wet bulb globe temperature index (wbgt) in women in the climate chamber . methods: this experimental study was carried out on 36 healthy females in sit...

BACKGROUND Airborne allergens, pollutants, and climatic changes are known to influence the symptoms of asthma patients. OBJECTIVE To correlate airborne fungal spore and pollen concentrations, meteorological data, and airborne pollutants with asthma and rhinitis symptoms to develop predictive models for asthma severity. METHODS Patients from the Tulsa community participated in this study fro...

within the climate change debate and its probable impacts on water resources systems, design and operation of management plans based on the assumption of stationary hydrology may cause serious challenge to accurately predict future supplies. therefore this case study is trying to assess trend in hydroclimatic variables of karkheh rivers upstream by applying modified mann-kendall trend test on l...
