INTRODUCTION The mosquito Aedes aegypti, vector of dengue, chikungunya and yellow fever viruses, is an important target of vector control programs in tropical countries. Most mosquito surveillance programs are still based on the traditional household larval surveys, despite the availability of new trapping devices. We report the results of a multicentric entomological survey using four types of...
Climate scientists have concluded that the air temperature of earth’s surface warmed to 0.6 during the 20th century, and that warming induced by increasing concentrations of greenhouse gases accompanied by changes in the precipitation and hydrologic cycle. Monthly, seasonal and annual precipitation trends of meteorological stations have been analyzed and interpolated in the northern part of Ira...
Annuals are an important component part of plant communities in arid and semiarid grassland ecosystems. Although it is well known that precipitation has a significant impact on productivity and species richness of community or perennials, nevertheless, due to lack of measurements, especially long-term experiment data, there is little information on how quantity and patterns of precipitation aff...
the effect of drought on the seed yield and some associated characteristics of common been under normal and drought stress conditions and determination of durable genotypes to drought were studied by planting 32 genotypes in two separate augmented designs in normal and stress conditions. these genotypes were evaluated in randomized complete block design with 3 replications in the field of facul...

Background Perfusion dyssynchrony analysis provides a novel insight into the evaluation of myocardial ischaemia due to coronary artery disease (CAD). Perfusion dyssynchrony indices measure differences in the temporal distribution of the wash-in of contrast agents across the left ventricular wall. In a previous 2D study the temporal dyssynchrony of LV perfusion was measured using four indices va...
to perform stability analysis and study g*e interaction, eight commercial sugar beet varieties were evaluated in eight major sugar beet producing areas of karaj, mashad, miandoab, esfahan, shiraz, kermanshah, moghan and hamadan in three years using a randomized complete block design with four replications. the evaluated varieties were br1, 7233, pp.8, ic, 7233-p29, pp22, h5505 and 41rt. having ...
Extended Abstract Introduction and Objective: Drought stress as one of the most important abiotic stress is the main limiting factor of oilseed rape cultivation in arid and semi-arid climates. Therefore, the identification of drought tolerant genotypes is the essential programs in these regions. One of the appropriate methods to identify drought tolerant genotypes is the use of stress toleranc...
