To understand the drought response mechanisms of dry matter partitioning maize, pot experiments under conditions were conducted during vegetative and reproductive growth periods maize. The aim was to calculate allometric relationships between weight different organs their responses drought. Results showed that roots, above-ground plant, total biomass gradually increased with maize approaching m...

An improved method of banking the donor material at low temperature is described, entailing the immersion of the cornea with an attached rim of sclera in medium containing dimethyl sulphoxide. The storage temperature is that of liquid nitrogen (1960 C.) instead of that of solid carbon dioxide (79° C.), as formerly used. Though the results with deep-frozen donor material were superior to those w...

Recent developments in climate change have increased the frequency of dust storms in the Middle East. Dust storms significantly influence the performances of solar energy harvesting systems, particularly (photovoltaic) PV systems. The characteristics of the dust and the mud formed from this dust are examined using various analytical tools, including optical, scanning electron, and atomic force ...

OBJECTIVES The C282Y allele is the major cause of hemochromatosis as a result of excessive iron absorption. The mutation arose in continental Europe no earlier than 6,000 years ago, coinciding with the arrival of the Neolithic agricultural revolution. Here we hypothesize that this new Neolithic diet, which originated in the sunny warm and dry climates of the Middle East, was carried by migratin...
