Extended Abstract Introduction: Seed germination is one of the most important factors which determine the success of failure of crop establishment. In the absence of other environmental limiting factors such as moisture, temperature would determine the rate and overall seed germination. This research was conducted to investigate the effect of temperature regimes on seed germination, quantify t...
Senescence is a factor limiting the marketing of most flowers and considerable effort has been applied using various treatments to increase longevity of flowers. Accordingly, a factorial experiment based on completely randomized design with two miniature carnation cultivars (Aragon and Erueka), two temperatures (2 and 4 ° C), 13 treatments (control treatment and various concentrations of amino-...
two different dual phase steels were prepared from low carbon manganese steel after the eliminationof the banding using the direct quenching (dq) and the step quenching (sq) procedures. different heattreatments resulted in different martensite morphologies, microstructures and mechanical properties. theheat treatments were designed in such a way to obtain a 0.25 volume fraction of martensite (v...
a cause for breakage of rice kernels during the whitening process could be assumed to be due to the produced heat. it is partly because of abrasion and friction of grains produced by contact against themselves and/or against cone and concave. in this study the effect of different temperatures of brown rice on rice kernels' breakage during the whitening process was investigated. khazar cult...
in order to evaluate the response of russian knapweed seeds to cardinal temperatures a factorial experiment was conducted base on completely randomized design with 3 replications. russian knapweed seeds (collected from irrigated and rainfed wheat fields), and germination temperatures (constant temperatures of 10, 15, 20, 25, 30 and 35° c) were used as first and second levels of the experiment. ...
a prediction of maximum monthly rainfall is indispensable for management of agriculture and for management of water resources. previous studies have demonstrated that see surface temperatures affect rainfall in their surrounding regions. in this study the relationship between sea surface temperatures of persian gulf and that of red sea, and maximum monthly rainfalls recorded at illam meteorolog...
Background: Fatigue is an important inhibiting factor in human performance, so with rising aerobic power could be overcome individual fatigue. Based on the importance of maximum oxygen consumption at fatigue threshold, the purpose of this study was to evaluate changes in temperature of the maximum rate of oxygen consumption and time to exhaustion in workers of spinning factory. Methods: In thi...
Background and Objectives: Food wastes are sometimes valuable; of which, seeds are significantly important. Grape seeds, as byproduct of grape processing, contain valuable substances for the production of advanced oils as well as feeds. Therefore, the major aim of this study was to assess moisture sorption isotherms of black grape seeds at various conditions. Materials and Methods: Moisture so...
chloritoid is crystallised with chlorite, white mica and garnet in chlorite zone metapelites ofthe regional metamorphic rocks of the sanandaj-sirjan metamorphic belt in southern iran. chemistry ofcoexisting minerals is studied using microprobe analysis. application of the chlorite-chloritoidgeothermometry gives temperatures of 515°c and 557°c. the chlorite-garnet fe-mg exchangegeothermometer in...
