climate change is defined as long term and irreversible changes in the climatic behaviorof a region. many studies have been conducted in different regions of the world on climatechange. the results of these studies show considerable changes in climatic factors especiallyin precipitation and temperature. in this research, the trend of changes in annual and seasonalrainfall and temperature in 24 ...
nitric oxide (no) is a small molecule synthesized by most of mammalian cells with diverse biological activities including vasodilatation, host defense and wound healing. impaired wound healing is a common occurrence among diabetics and patients receiving glucocorticoid therapy. on the other hand the application of laser in biomedical area have been increased. thus, the current studies were desi...
introduction: air temperature as an important climatic factor can influence variability and distribution of other climatic parameters. therefore, tracking the changes in air temperature is a popular procedure in climate change studies.. according to the national academy in the last decade, global temperature has raised 0.4 to 0.8⁰c. instrumental records show that, with the exception of 1998, th...
in this research,the authors conducted a study comparing two groups of male and female english language learners studying in a elt institute,in terms of their performance on their achievement test including listening comprehension,vocabulary,grammar,and reading comprehension and found no significant difference between the group except in listening comprehension part of the test in which the f...
Trend Analysis of the Streamflow in the Lighvan River hydrometric Stations (Upstream and Downstream)
In recent years, rivers flows have significantly decreased due to regional or global climate change and human activities especially in the arid and semi-arid regions. In this study, the effect of climate change and human activities on the runoff responses was examined using hydrologic model simulation in the Lighvan basin located in the northwest of Iran. For determination of hydrologic model M...
Considering the vast application of sea surface temperature in climatic and oceanic investigations, this parameter was studied in Oman Sea from 1986 to 2015. The SST was surveyed using trend analysis and Global and local Moran’s I spatial autocorrelation. In trend analysis, the Mann-Kendall test was used to determine the trend of SST changes and the Sen's Estimator method was used to examine th...
Background and purpose: Human health is affected by a variety of human and natural phenomena that surround the environment. Atmospheric pollutants and thermal comfort conditions concern the quality of surrounding air. Given the influential role of lakes on the climatic conditions of their surrounding environment, the effect of different scenarios of Maharlu Lake in the southeastern part of Shir...
analysis of the spatial and temporal trends of precipitation and temperature are pertinent for future development and sustainable management of water resources in a given region. in this paper, we present a study concerning the climatic behavior of two principal observables variables, viz. monthly temperature (maximum and minimum) and mean precipitations obtained from the measurements carried o...
