The need of a better adaptation of crops to drought is an issue of increasing urgency. However, enhancing the tolerance of maize has, therefore, proved to be somewhat elusive in terms of plant breeding. In that context, proper phenotyping remains as one of the main factors limiting breeding advance. Topics covered by this review include the conceptual framework for identifying secondary traits ...

Global food security largely depends on the crop yield increase, so study of yield-limiting factors potato (the second bread) is a pressing issue today. This determines contribution agroecological factors, namely, bioclimatic variables, soil indicators, and landscape diversity, to variation in yields. Conducted Polissya Forest-steppe zones Ukraine during 1991–2017, this has not only addressed r...

The relatively low levels of transfection that can be achieved by current gene delivery systems have limited the therapeutic utility of gene transfer. This is especially true for non-viral gene delivery systems, where the levels of gene expression achieved are usually well below the levels achieved by viral gene transfer systems. Previous work from our laboratory describes an enhanced dual prom...

In this study, qualitative land suitability evaluation was made for research station of East Azarbaijan, for tomato, potato, onion and bean. The study was done using Simple Limitation Method (SLM), Limitation Method regarding Number and Intensity (LMNI) and Parametric Methods (PM) such as the square root and the Storie methods. The results from different methods indicated that the most importan...

drought is one on the most important factors limiting the productivity of spring chickpea in drylands of iran. sixtym genotypes of chickpea from icarda's germplasm accessions, as well as one drought susceptible check (ilc 3279), were sown in spring of 2010 at two locations, sanandaj and maragheh, in the western highlands of iran for one year. the experiment in each location was laid out in a ra...

Each year in the past three decades has seen hundreds of thousands of runners register to run a major marathon. Of those who attempt to race over the marathon distance of 26 miles and 385 yards (42.195 kilometers), more than two-fifths experience severe and performance-limiting depletion of physiologic carbohydrate reserves (a phenomenon known as 'hitting the wall'), and thousands drop out befo...

INTRODUCTION: Rapid urbanization and population expansion, coupled with sustained income growth and the emergence of an urban African middle class are triggering an increase in the consumption of animal protein in developing countries. The sustained increase in the consumption of animal proteins creates a host of new development opportunities to synergistically link smallholder livestock produc...

There are many approaches to computational simulation of turbulence. These include field computations based on Navier Stokes Equations, various forms of discrete simulation involving particles and vortices or vortex sheets, and phenomenological approaches such as large eddy simulation. Turbulence is striking because of the large range of scales encountered, which in computational terms means th...
