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 ...

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...
