abstract temperature is the most important environmental factor that affects flowering and fruiting. the temperatures induce reproduction and cause damaging to tree or its crop.this paper analyzed daily minimum temperatures 0.0oc, and maximum temperatures 12.5 oc from october 1 to may 31 at nine sites in olive producing and cultivating regions, and one control station, using thermal adaptabilit...

Climate change due to increasing the concentration of greenhouse gases (especially CO2) in the atmosphere causes changes in the rainfall regime, runoff rate, wind speed and solar radiation of atmosphere. In the present research, the maximum and minimum temperature parameters were simulated during the base period of 1979-2088 and two future periods of 1979-2070 and 2070-2090 using daily ...

In order to reduce wear in gudgeon pin, bush and piston boss lubrication is done. Oil used in national engine species was 10W40 with dynamic viscosity 5.5 mPa.s at 140 °C (the working temperature). In order to complete investigation the oil film hydrodynamics analysis in small end of connecting rod, a real full model engine with four cylinders has been simulated by AVL EXCITE5.1 software. In...

Climate change, with effects on temperature and rainfall, has a great influence on dry period. Therefore, it is very important to study this phenomenon in the analysis of dry period length. In this study, we used GFDL-ESM2M and four RCP scenarios to simulate precipitation, maximum and minimum temperature and used CCT with statistical methods to downscale the results. The data used in this study...

In this experiment six healthy adult dairy Jersey cattles and eight calves (aged 4-6 months) were selected to measure temperature of different body skin sites, rectal temperature, respiration and heart rates during summer and winter. Body sites maximum and minimum temperature in calves during summer belonged to the ear, forehead, right flank, abdomen (38.4-38.9 ˚C) and carpus (32 ˚C). This was ...
