ABSTRACT- In this study, effect of deficit irrigation with different salinity levels and planting methods (in-furrow and on-ridge) on nutrient and toxic ions uptake by rapeseed was investigated in a two-year experiment. The experiment was conducted at Research Station, located in the College of Agriculture, Shiraz University, I.R. of Iran. Results indicated that an increase in water stress leve...

Objective(s): Noise-induced hearing loss (NIHL) is the major cause of acquired hearing loss.  Celecoxib, a cyclooxygenase-2 (COX-2) inhibitor, is a non- steroidal anti- inflammatory drug (NSAID) with known antioxidant and antineoplastic activity. Therefore, we monitored the extent of temporary noise- induced threshold shifts (TTS) and cochlear damage caused by high level 4- kHz noise exposure t...

Field microplot experiments were conducted from 1987 to 1992 to determine the relationship between fresh weight leaf yield of shade tobacco (Nicotiana tabacum) and initial density of Globodera tabacum tabacum (encysted J2 per cm(3) soil). Initial nematode densities of 0.1 to 1,097 J2/cm(3) soil were negatively correlated with leaf yield, total shoot weight, and normalized plant height 5 to 6 we...

the yield loss simulation (yls) and the macros liq.csm models were used to simulate the effect of stem borer damage at a detillering rate of 5, 15, 30, 60% at vegetative, panicle initiation and grain filing stages, on yield of rice cultivar?s ratna. this stem borer damage during vegetative and panicle initiation stages was not simulated appropriately by both the models. relatively macros simula...

the performance of different yield loss models from an exponential family was evaluated in safflower-redroot pigweed systems in two field experiments conducted during 2007 and 2008 growing seasons at the research field of agricultural college of shiraz university, iran. the yield loss of safflower was recorded as relative yield loss in experimental plots laid out in split plot design with three...

Introduction: Sensorineural hearing loss (SNHL) is a probable complication of coronary artery bypass graft (CABG) Surgery, that may be due to embolism, perfusion failure and consumption of ototoxic drugs. Since the incidence of SNHL after CABG is different according to the various reports, the present study was designed to study hearing threshold change after CABG surgery. Method: In this cross...

introduction: occupational exposure to excessive noise is commonly encountered in a large number of industries in iran. this study evaluated the hearing threshold and hearing loss in meybod tile factory workers. methods: this cross-sectional study included 371 tile factoryworkers during summer and autumn of 2005. current noise exposure was estimated using sound level meter .a specially formatte...
