limited information is available on water and nitrogen (n) management of sugarcane (saccharum officinarum l.) in khuzestan, southwestern iran, where this crop is currently and extensively grown under heavy irrigation and n fertilization. therefore, a field experiment was conducted from september 2000 to march 2002 at the research department of karoon agro-industry in khuzestan to determine the ...

Our work in the last year focused on improving the sorting of semiconducting carbon nanotubes and the enhancement of the conductivity and transparency of carbon based electrodes. The active layer of our carbon solar cell is based on semiconducting single-walled carbon nanotubes; the highly selective sorting of small diameter carbon nanotube is essential for photovoltaic applications. Ideally, t...

Mid-infrared laser ablation of water-rich targets at the maximum of the 2.94 mm absorption band is a two-step process initiated by phase explosion followed by recoil pressure induced material ejection. Particulates and/or droplets ejected by this high temperature high pressure process can be ionized for mass spectrometry by charged droplets from an electrospray. In order to gauge the internal e...

in the last decades, rice yields in south asian countries grew tremendously in one hand and a noticeable yield fluctuation on the other. the objective of this study was to examine the rice yield distributions, estimate yield risks at country level, and compare risks between five countries namely afghanistan, bangladesh, nepal, sri lanka, and pakistan. anderson darling (ad) test was applied to t...
