water productivity increase is one of the water management solutions in agriculture and increasing its efficiency. the accurate determination of plants water requirement and the accurate value estimate of evapotranspiration is essential for improving water productivity in irrigation network that it can help to improve water management in agriculture. in this research such climatic elements as t...

The aim of this study was evaluate the behavioral responses of rainbow trout (Oncorhynchus mykiss) exposed to changes in temperature and ammonia. For this purpose were placed separately 8 rainbow trout (average weight of 6±2g, length 5±2 cm) in the treatment and control groups with four replicates in five-liter tanks (cross-sections 7 cm, height 4 cm) Each the tanks have a water inlet and outle...

in suspension polymerization, particle size distribution of polymer is the outcome of dynamic equilibrium between the break up and coalescence phenomena. the rates of break up and coalescence and consequently polymerization stability depend on several parameters, the most important of which are type and concentration of stabilizer. in this study, the effects of type and concentration of stabili...

To study the effect of climatic factors on Taverniera glabra species distribution in Iran rangelands, climatic variables were selected and factors affecting species distribution were evaluated using factor analysis. Then a spatial distribution map was prepared for all these factors throughout Iran. Factor analysis showed that 9 factors included: temperature, relative humidity, winter precipitat...

A study was conducted to determine the effects of water temperature and rations size on growth performance, feed utilization and carcass biochemical composition of juvenile Benni. Six treatments representing a combination of two water temperature (24 and 28 °C) and three feeding rations (1%, 3% and 5%) were tested with three replicates. Each replicate was stocked with 12 fish (30.66±0.81 g aver...

We consider the relation between the Boltzmann temperature and the Lagrange multipliers associated with energy average in the nonextensive thermostatistics. In Tsallis’ canonical ensemble, the Boltzmann temperature depends on energy through the probability distribution unless q = 1. It is shown that the so-called ’physical temperature’ introduced in [Phys. Lett. A 281 (2001) 126] is nothing but...
