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...

background acoustic trauma is an injury to the hearing mechanisms in the inner ear due to excessive noise. this injury is the most prevalent cause of sensorineural hearing loss in humans, especially from occupational exposure. previous studies have shown the essential role of free radical formation in the inner ear hearing loss caused by acoustic trauma. objectives this study was performed to d...

In this study, we estimate yield losses and economic damage of two major crops (winter wheat and rabi rice) due to surface ozone (O3) exposure using hourly O3 concentrations for the period 2002-2007 in India. This study estimates crop yield losses according to two indices of O3 exposure: 7-h seasonal daytime (0900-1600 hours) mean measured O3 concentration (M7) and AOT40 (accumulation exposure ...

0018-9251188/1100-0678 $1.00 (C 1988 IEEE Ordered statistics (OS) constant false alarm rate (CFAR) algorithm, introduced by Rohling [ I ] , is a CFAR technique with special immunity to interfering targets. CFAR usually suffers some detection loss due to the adaptive threshold concept. Furthermore, the presence of strong returns among the cells used to determine the background noise or clutter (...

Rising levels and spread in IDDQ values render single threshold IDDQ testing obsolete for highperformance chips for deep sub-micron technologies. Increased inter-die and intra-die variations cause unacceptable yield loss with a single pass/fail limit. Use of spatial information to estimate fault-free IDDQ is investigated. Flush delay information is used to refine this estimate under varying pro...

considering the extent of salinity in soils of iran, abiotic stresses such as salinity are serious threat to agricultural production, yield and essential oil of medicinal plants. recognition of threshold for salt tolerance and determining the slope of yield loss in medicinal plants has an important role in the selection of suitable lands for their cultivation. the effect of salinity stress on s...
