The objective of this experiment was to analyze genotype × environment (GE) interaction for grain yield of 20 durum wheat genotypes to identify the yield stability and adaptability of genotypes using GGE biplot method as well as some univariate stability statistics. The genotypes were evaluated in three rainfed stations of Sararood (Kermanshah), Maragheh and Shirvan, Iran under both rainfed and...

Topography in East Nusa Tenggara Province dominate by dryland and slope land. In the farmers develop farming system of maize as a staple crop. Dryland potential for food crop Bali reach 645,891 ha but have low fertile productivity maize. Productivity only 2.7 ton/ha. This is lower if compare with average national level result research. The objective research to get specific technology cultivati...

A large number of vegetation indices have been developed and widely applied in terrestrial ecosystem research in the recent decades. However, a certain limitation was observed while applying these indices in research in dry areas due to their low sensitivity to low vegetation cover. In this context, the objectives of this study are to develop a new vegetation index, namely, the Generalized Diff...

extended abstractintroductionsiberian high-pressure is one of the most important systems in climatology, which has been focused by all climatologists because of its influence area and expansion zone.unique features of this system including the expansion zone,the intensity of central pressure,which sometimes amounts to more than1075hp pressure at its core,its temperature and moisture characteris...

An advection–diffusion model of fluvial processes was used to analyze the stratigraphic expression avulsions in terminal river systems and understand their control on basin-fill architecture. The initial boundary conditions runs (i.e., catchment area, smoothed topographic surface, grain-size distribution sediment supply rates) were extracted from modern Rio Colorado dryland system Altiplano Bas...

The spatio-temporal variability of trends in vegetation greenness in dryland areas is a well-documented phenomenon in remote sensing studies at global to regional scales. The underlying causes differ, however, and are often not well understood. Here, we analyzed the trends in vegetation greenness for a semi-arid area in northeastern Brazil (NEB) and examined the relationships between those dyna...

triploidy in grass carp, ctenopharyngodon idella valenciennes, 1844, was induced on fertilized eggs to compare cold and heat shocks. two simplified methods explained for verification of triploidy in grass carp. the cold shock (7 ?c) was given in three treatments for 30 min starting 2.0, 2.5 and 4.0 min after fertilization. in cold shock, the start point (2.0 min after fertilization) showed the ...

BACKGROUND Mild cold exposure increases energy expenditure and can influence energy balance, but at the same time it does not increase appetite and energy intake. OBJECTIVE To quantify dermal insulative cold response, we assessed thermal comfort and skin temperatures changes by infrared thermography. METHODS We exposed healthy volunteers to either a single episode of environmental mild cold...
