in drought stress condition, it is important to estimate the n and k requirement of sugar beet. a drought-tolerant sugar beet genotype, bp karaj, was evaluated in split plot factorial design based on a randomized complete block design with four replications at motahari research station, karaj, iran for three years. main plots were allocated to irrigation treatments including normal irrigation (...

A new mite species of the genus Nothrholaspis Berlese, Nothrholaspis saboorii Babaeian & Joharchi sp. nov., is described and illustrated from specimens collected from soil in the Karaj region of Iran. An identification key for the known species of Nothrholaspis is presented.

for evaluation of drought tolerance of sugar beet genotypes by assessment of the drought tolerance indices under mild and severe stresses, furrow irrigated field experiments were carried out at zarghan research station in 2002 and 2004, and at motahari research station (located inkaraj) in 2002, 2003, and 2004. the experimental design was split plot, with a randomized complete block arrangement...

BACKGROUND It is clear that tobacco smoking and substance abuse have negative consequences on adolescent and youth's health. Tobacco smoking especially hookah smoking has increased worldwide especially among university students. This study aimed to determine the prevalence of risk-taking behaviors such as cigarette smoking, hookah smoking, alcohol use, and drug abuse and its predictors in stude...

Flexible Dual-TCP/UDP Streaming Protocol with Bitstream Prioritization (FDSP-BP) is a new method for streaming H.264-encoded High-definition (HD) video over wireless networks. This paper presents a novel technique to adaptively modify the Bitstream prioritization (BP) parameter based on network conditions. This technique selects the maximum BP value that satisfies the Transmission Control Proto...

The Tibetan Plateau (TP) is primarily influenced by the northern hemispheric middle latitude Westerlies and the Indian summer monsoon (ISM). The extent, long-distance effects and potential long-term changes of these two atmospheric circulations are not yet fully understood. Here, we analyse modern airborne pollen in a transition zone of seasonally alternating dominance of the Westerlies and the...
