The forms of the quanitative relationship between temperature and the responses of animals to light might be expected to differ according to the aspect of reaction which is measured as index of excitation. Thus in the clam Mya (Hecht, 1919-20, a) the primary photic excitation process for siphon retraction has a very low temperature coefficient such as is characteristic of photochemical changes,...
The main problem when treating industrial wastewater is the removal of dyes. Some of the physical and chemical treatment techniques were effective but they might result in the production of toxic by-products and could also be the cause of a secondary pollution problem due to excessive chemical use. In order to overcome the drawbacks, the present work has focused on the biodegradation of dyes us...
The most common building material utilized worldwide is concrete. Concrete with higher compressive strength becoming more and in demand as the trend toward using it widely for high rise buildings. Experimental study of glass fiber (GF) reinforced concrete incorporating micro silica was investigated this study. prepared by M40 mix. GF 12 mm length aspect ratio 857 used. Four volume fractions 0%,...
Objective of this study is to determine whether there are significant changes in maximum temperature trends between the current (1981-2010) and future (2011-2099) periods. To this end, statistical downscaling is used to project future changes in the maximum temperatures according to A2 and B2 scenarios of HADCM3 in the 7 selected stations of Iran. The possibilities of an accelerating trend are ...
In this essay, we investigated the effects of climate change on the rivers of selected basins of Guilan province, one of the northern provinces of Iran for the period 2020 to 2050 under three climate scenarios: RCP2.6, RCP4.5, RCP8.5. For this purpose, rainfall and temperature data from 45 climate data stations and 20 hydrometric stations from 1983 to 2013 were used. The average precipitatio...
Climate change has important effects on earth environment and human life. Therefor, investigation and study of climate change is very essential. This study investigated rainfall, temperature, relative humidity and wind variability by analyzing data for annual and monthly climatic factors collected at 13 synoptic stations (industrial cities of Iran) by using Mann-Kendall test. The results of mon...
We give an optimal wait free implementation of an increment register An increment register is a concurrent object consisting of an integer valued register with an increment operation that atomically increments the register and returns the previous value We implement this register in a synchronous message passing model with crash failures In our implementation an increment operation halts in O l...
Fluctuations in the meteorological variables such as: temperature, precipitation, is one of the atmospheric circulation characteristics. Meanwhile, the sharp decrease of precipitation and dry periods caused by that has many negative effects on water resources. Climatic fluctuating in a region has severe effect on soil and water resources. Nowadays, generally it has been accepted that any change...
