Photosynthesis is the basic process influencing crop productivity. It can be inhibited by drought. Seven sour cherry genotypes were challenged by drought to assess their photosynthetic efficiency in such conditions. All together with relative water content (RWC) as indicator of plant water status, maximum quantum yield of photosystem II (Fv/Fm) and chlorophyll content (Chl a+b) differentiated i...

In most prokaryotes Asn-tRNA and Gln-tRNA are formed by amidation of aspartate and glutamate mischarged onto tRNA and tRNA, respectively. Coexistence in the organism of mischarged Asp-tRNA and Glu-tRNA and the homologous Asn-tRNA and Gln-tRNA does not, however, lead to erroneous incorporation of Asp and Glu into proteins, since EF-Tu discriminates the misacylated tRNAs from the correctly charge...

The gustatory and olfactory systems are the only two systems in which stimuli act directly on the receptor. There are five taste categories which have been identified as gustatory stimuli: sweet, salty, bitter, sour, and umami (MSG). Bitter and sour are known as aversive stimuli and help mammals avoid toxic and spoiled foods. Although both are similar in that they are aversive, they work throug...

Blind sour e separation (BSS) de omposes a multidimensional time series into a set of sour es, ea h with a one-dimensional time ourse and a xed spatial distribution. For EEG and MEG, the former orresponds to the simultaneously separated and temporally overlapping signals for ontinuous non-averaged data; the latter orresponds to the set of attenuations from the sour es to the sensors. These sens...

Abstra t | In this work, we investigate the joint sour ehannel oding issue of transmitting non-uniform independent and identi ally distributed (i.i.d.) sour es over additive white Gaussian noise (AWGN) hannels via Turbo odes. The sour e redundan y in the form of non-uniformity is exploited in the Turbo de oder via a modi ed extrinsi information. In ontrast to previous work, non-systemati re urs...

Background: Combustion of fossil fuels contributes to sulfur dioxide (SO2) emissions. To deal with this issue, the government of Iran has appointed the oil refineries to upgrade their installations and produce high quality fuels. Thus, this study investigated the status of SO2 emissions in Iran and the capability of advanced technologies to control SO2 emissions. Methods: The status of SO2 em...
