Using 15-yr data from the European Centre for Medium-Range Weather Forecasts Re-Analysis (ERA15), the authors found that rapid southeastward expansion of the rainy area from the western Amazon to southeastern Brazil is a result of midlatitude cold air intrusions. During austral spring, as the large-scale thermodynamic structure over Amazonia becomes destabilized, the incursions of extratropical...
pishgam was selected from the progeny of a cross between barakat iranian bread wheat cultivar and chinese 90-zhong 87 winter-habit ( bkt/90-zhong 87) in 1995. the f1 generation seeds were planted in karaj station in 1995-96 cropping season. selected-bulk method was applied to segregating generations from f2 to f5 generations for characters such as winter hardiness, plant height, straw strength,...
Understanding the patterns of spatial and temporal distribution in threshold habitats of highly migratory and endangered species is important for understanding their habitat requirements and recovery trends. Herein, we present new data about the distribution of humpback whales (Megaptera novaeangliae) in neritic waters off the northern coast of Peru: an area that constitutes a transitional path...
AIM Present study aimed to evaluate the different episodes of clinical mastitis (CM) and influence of duration of treatment and seasonality on the occurrence of different episodes of CM in crossbred cows. MATERIALS AND METHODS A total of 1194 lactation data of crossbred CM cows were collected from mastitis treatment record from 2002 to 2012. Data of CM cows were classified into types of episo...
the indian riverine buffaloes are more susceptible to variations in the environment. these variations affect seminal plasma proteins, which in turn affect fertility. this study was conducted to evaluate variations in the indian bubalus bubalis seminal plasma protein profile using two-dimensional polyacrylamide gel electrophoresis (2d-page) during winter and summer seasons, and its relation with...
Considering that habitat use by amphibians is related both with climate and environmental features, we tested the hypothesis that anuran assemblages found in different phytophysiognomies and in different seasons vary in structure. Additionally, we searched for species which can be indicators of habitat and seasons. The study was conducted in the Pampa biome, southern Brazil. Sampling was done t...
Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous; some of them have been paid more attention due to their carcinogenic and mutagenic properties. Atmospheric deposition is an important process for air-surface exchange of polycyclic aromatic hydrocarbons (PAHs). A yearround bulk (wet plus dry) deposition sampling campaign in mountain, plain, and basin sites was conducted in Chengdu Economic...
BACKGROUND The effect of seasons on health outcomes is a reflection on the status of public health and the state of development in a given society. Evidence shows that in Sub-Saharan Africa, most infectious diseases flourish during the wet months of the year; while human activities in a context of constrained choices in life exacerbate the effects of seasons on human health. The paper argues th...
background and purpose: today, by increasing different pollutants, the continuous monitoring of surface waters is essential. dorudzan dam is one of the main sources of surface water in fars province, iran; hence, the current study investigated the quality of dorudzan reservoir for drinking and irrigation consumptions. materials and methods: in this study, various physicochemical parameters [ph...
The purpose was to test the effect of eccentric strength training and flexibility training on the incidence of hamstring strains in soccer. Hamstring strains and player exposure were registered prospectively during four consecutive soccer seasons (1999-2002) for 17-30 elite soccer teams from Iceland and Norway. The first two seasons were used as baseline, while intervention programs consisting ...
