the objective of this study is to investigate of climate change in gorgan river-gharesoo basin and these impacts of this phenomenon on regional land use change, as well as provide guidance on the effective management and conservation of natural land area. analysis of climate data including rainfall, average temperature and relative humidity of nine synoptic stations in this area from east to we...

kermanshah station as station coordinates 34 degrees 21 minutes north latitude and 47 degrees9 minutes east longitude has been extreme temperature fluctuations and predict for the analysis of kermanshah and their relationship with the nao is considered to carry out this study, data relating to the maximum annual absolute maximum temperature.. رnowadays one of the most important discussions in t...

The objective of our study was to establish whether rectal temperature recordings in humans could be replaced by a non-invasive skin temperature sensor combined with a heat flux sensor (Double Sensor) located at the forehead to monitor core body temperature changes due to circadian rhythms. Rectal and Double Sensor data were collected continuously for 24h in seven men undertaking strict head-do...

the variation in climatic variables like temperature, humidity and radiations were recognized as the potential hazards in the growth and production of all domestic livestock species. thermal environment is a major factor that can negatively affect both production and reproduction in dairy animals, especially in animals of high genetic merit. among the stressors, heat stress has been of major co...

in this study chemical method of dissolution-precipitation was applied to produce amorphous silica nanoparticles from rice straw ash (rsa), the waste material of rice cultivation. the morphology, particle size, structure and area of specific surface of synthesized amorphous silica nanoparticles were evaluated using transmission electron microscopy (tem), x-ray diffraction analysis (xrd) and bet...

Lack of reliable long-term precipitation record from northern Tibetan Plateau has constrained the understanding of precipitation variation in this region. An ice core drilled from the Puruogangri Ice Field on central Tibetan Plateau in the year 2000 helped reveal the precipitation variations since AD 1600. Analysis of the annual accumulation 5 data presented precipitation changes from AD 1600, ...

introduction today, with the increasing population and the need for strategic and industrial crops the farmers are simulated to grow these kinds of crops. thus, this subject has now been caused the inappropriate use of land and natural resources. on the other hand, the natural environment resources have limited the ability to use its resources and the climate change intensifies this limit abili...

in this paper trends of precipitation and stream flow are analyzed in the atrak river basin in the north khorasan province. normal score linear regression, mann-kendall, and seasonal kendall trend tests were adopted. three precipitation variables and two stream flow variables including total precipitation, maximum daily precipitation, and number of rainy days, mean discharge and peak discharge ...

over the coming decades, global change will have an impact on food and water security and there are strong indications that developing countries will bear the brunt of adverse consequences from climate change. agricultural sector is the most vulnerable to climate change, because of its dependence on water and temperature conditions. consequently, it is important to understand the impacts of cli...
