Temperature change in the future, which is very important in terms of agriculture, development and health, can be one of the consequences of climate change and global warming. Knowing how it can be a significant help to the agricultural sector and development issues and managerschr(chr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39')))39chr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39')...
The main objective of this study was to reveal the impact of nine climate indices on temperature changes and climate oscillations in Golestan Province along the southern coast of the Caspian Sea. Climate indices data from across the Atlantic-Eurasian sector were collected from the NCEP/NCAR, the Climate Prediction Centre (CPC) and the Climatic Research Unit (CRU) over a period of 40 years (1971...
radiation input from the sun is the source of energy for the earth’s climate system (hartmann, 1994). most of the solar radiation absorbed at the surface, the rest is absorbed by the atmosphere. the global temperature profile of the atmosphere reflects a balance between the radiative, convective, and dynamical heating/cooling of the surface-atmosphere system. understanding of the climate change...
BACKGROUND The purpose of this study was to evaluate the effects of benzalkonium (BAK)-free travoprost monotherapy administered for 3 years on intraocular pressure and visual field performance. METHODS The intraocular pressure of 76 patients with normal tension glaucoma was monitored every 1-3 months. A Humphrey visual field test was performed every 6 months after treatment and compared with ...
2 " Greenhouse gases are accumulating in Earth's atmosphere as a result of human activities, causing surface air temperatures and subsurface ocean temperatures to rise. From the Kyoto Protocol to domestic policies to restrict carbon emissions to proposed taxes on fuel and coal derivatives, national and international governments have embraced the call to combat global warming. 1 There remains li...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
abstract in the present research solution of chalcopyrite in sulfuric acid in hydrometallurgy method using electrochemistry with cyclic voltammetry technique has been investigated. the value of maximum reduction peak current of copper ions represents the measure of solubility. in this research different parameters temperature, potential, potential exert time, chalcopyrite concentration, sulfur...
The climate change in Shandong Peninsula, China was analyzed in this paper by the non-parametric Mann-Kendall test, Accumulated Difference Curve and Order Cluster Analysis methods, based upon the datas of annual mean, maximum and minimum temperature and annual precipitation, precipitation from June to September over the past 50 years. Results obtained showed a number of observations: 1) The ann...
Mehrgerd region of Semirom county has faced the water shortage for several years. The emergence of drought has led to a decline in water resources in recent years; and there are various reasons for climate change and increased consumption in order to reduce water resources. The present study aimed to investigate the process of temperature and precipitation variations and its possible effects on...
