Through a modeling approach, we investigated weather factors that affect the summer incidence of Tomato spotted wilt virus (TSWV), a virus vectored exclusively by thrips, in cultivated tobacco. Aspects of thrips and plant biology that affect disease spread were treated as functions of weather, leading to a model of disease incidence informed by thrips and plant biology, and dependent on weather...
Disturbances of the space environment are a critical aspect of Space Weather and of the NSF Geospace Environment Modeling (GEM) program. Other than for the the stormtime ring current, which forms within the inner magnetosphere, the primary space weather disturbances occur within the plasma sheet of the magnetotail and couple along magnetic field lines to the auroral ionosphere. At the time of i...
the importance of writing as a complex skill in applied linguistics has drawn the attention of many researchers to evaluate textbooks in order to help learners gain self-sufficiency and autonomy in the field of language use and communication. investigations have shown that developments in textbooks evaluation can promote the quality of pedagogies and consequently the learning. this study attemp...
the application of e-learning systems - as one of the solutions to the issue of anywhere and anytime learning – is increasingly spreading in the area of education. content management - one of the most important parts of any e-learning system- is in the concern of tutors and teachers through which they can obtain means and paths to achieve the goals of the course and learning objectives. e-learn...
During the last two decades, forest condition in Germany and in some other parts of Europe has stabilized,1 because the emission of harmful pollutants and their deposition in the forests was lowered substantially.2 The still enduring deposition of nitrogen compounds in a typical size between 16 and 20 kg/(ha*a) in German forests exceeds natural levels and must be evaluated as a potential danger...
conclusions the results showed that, compared to participants with normal weights, physiological and thermal perceptual responses were higher in overweight participants. therefore, overweight individuals should avoid hot/dry weather conditions to decrease the amount of heat strain. results in both groups, oral temperature, heart rate, and thermal perceptual responses increased during heat expos...

Introduction and Background: The agricultural sector is one of the most important economic sectors due to extensive interaction with the environment, the greatest impact of climate change takes effect. The agricultural sector affects climate change and affects climate change. Climate change, on the one hand, affects agricultural performance and, on the other hand, affects the price of produ...
This paper provides a general overview of climatic extremes, how they may be defined and what they represent both in statistical and in physical terms, as well as the impacts they are capable of generating. A particular case study, namely the heat wave that affected many parts of Europe from June-August 2003, will be discussed in some detail. The final part of the paper will investigate, on the...
