in order to assess the performance of two soybean cultivars produced in two regions including karaj and moghan to drought stress at reproductive stages and also the impact of drought stress on yield and its components, oil and protein percent, an experiment was conducted as a split factorial based on complete randomized block design in three replications in agriculture faculty of tarbiat modare...

Blue light is known to induce suppression of stem elongation. To avoid the complication of blue-light-induced transformation of phytochrome we have adapted the procedure of measuring blue-light-induced suppression of stem elongation in Pisum sativum L. var Alaska grown under continuous red light. The resulting fluence-response curve for suppression of epicotyl elongation measured twenty-four ho...

To develop the organic Rankine-vapor compression ice maker driven by solar energy, a thermodynamic model was developed and the effects of generation temperature, condensation temperature, and working fluid types on the system performance were analyzed. The results show that the cooling power per square meter collector and ice production per square meter collector per day depend largely on gener...

We describe the design and performance of a bright, full-color, video-input display monitor that can produce image luminances as high as 50,000 cd/m2 for images 15 x 10 deg in size. We have constructed this device by rearranging the components of a commercially available projection television. Our display device allows an experimenter to evaluate human visual responses to complex spectro-spatio...

The Call Set up Success Rate is one of the most important Key performance Indicators (KPIs) used by all mobile operators. However there is no standard measurement possible for this parameter. Therefore the different operators can measure it differently. In this paper, a definition of a real Call Set up Success Rate, possibility of its implementation using the current technologies in GSM and dif...

Previous studies have found an increase in peripheral target localization errors in normally sighted older adults. These results have been interpreted as indicative of a constriction of the "useful field of view". In the present study, we parametrically manipulated masking, distractors and stimulus luminance and examined the relationships between peripheral target localization and age. We found...

the objective of this study was evaluation of salt tolerance of elite forage sorghum lines in laboratory and field conditions. salinity treatments were 5, 10, 15, 20, 25, 30 decisimens per meter in laboratory and distilled water as control. lines were kfs1, kfs2, kfs3, kfs4, mfs1, mfs2 and lfs56. the lines also cultivated in saline and non saline field conditions during 2004-2005. electrical co...

this research was conducted on determination of better planting distance and better amount of nitrogen and phosphorus for hybrid rice (bahar 1). planting distance were used in this experiment, include 30×15, 30×20 and 30×25 cm as main factor. and also nitrogen fertilizer was used, include four levels, 65, 95, 125 and 155 k/ha and phosphorus fertilizer used include tow levels, 50 and 100 k/ha as...

to study response of bread wheat cv. sardari to row spacing and seeding rate and to determine the desirable seed density under cold rain-fed conditions a two-year study (2008 and 2009) was carried out in qamloo research station located in kurdistan. a strip plot design with three replications was used. four rows spacing including 15, 17.5, 20 and 25 cm as horizontal factor and four seeding rate...
