an experiment was conducted in order to evaluate the effects of humic acid spraying on  grain yield and yield components of wheat, in agricultural research and natural resources center of tehran province, in 2010-11. a split-plot layout within randomized complete block design with three replications were used. main plots were three irrigation treatments contains of normal irrigation, non-irriga...

introduction: pomegranate (punica granatum l.) belong to punicaceae family is native to iran and grown extensively in arid and semi-arid regions worldwide. pomegranate is also important in human medicine and its components have a wide range of clinical applications. cracking causes a major fruit loss, which is a serious commercial loss to farmers. fruit cracking, seems to be a problem that less...

For the first time lactic acid was applied as an efficient and green catalyst for the one-pot three-component synthesis of amidoalkyl naphthols via the condensation between arylaldehydes, 2-naphthol and amides or urea under thermal solvent-free conditions in good to excellent yields. We have demonestrated a mild and efficient eco-friendly tandem synthesis of amidoalkyl naphthols using lactic ac...

in order to evaluate row spacing and microelements spraying on yield and some morphological traits ofpeppermint, a split plot experiment was conducted based on randomized complete block design with fourreplications in sari agricultural sciences and natural resources university during 2010-2011. threelevels of row spacing (50 × 10, 50 × 20 and 50 × 30 cm) and two levels of microelements (no spra...

abstract- a real-time, site-specific, machine-vision based, inter-row patch herbicide application system was developed and evaluated. the image resolution was 640 × 480 pixels covering a total area of 350 mm x 240 mm of a field composed of four quadrants of 350 mm x 60 mm each. the image frames were processed by labview® and matlab®. the developed algorithm, based on weed coverage ratio and seg...

-Frequent toxicant analyses are essential for good quality data in long-term continuous-flow tests. Due to the time consuming and costly chemical analyses, exposure levels are measured at best on a daily basis. These infrequent determinations may not detect variability in toxicant concentrations that could result in test failures. To minimize repetitive testing and improve data quality, a dye t...

The detection of structural changes in time series from industrial processes monitoring is of great interest. We investigate the limits and possibilities of two recently developed methods, one for the off-line detection of changed volatilities [Wied et al., 2011] and one for the on-line detection of changes in the course of the time series [Borowski and Fried, 2011]. The investigation is carrie...
