Neurological glutamate receptors bind a variety of artificial ligands, both agonistic and antagonistic, in addition to glutamate. Studying their small molecule binding properties increases our understanding of the central nervous system and a variety of associated pathologies. The large, oligomeric multidomain membrane protein contains a large and flexible ligand binding domains which undergoes...

Continuous hydrogen photo-production under sulfur deprivation was studied in the Chlamydomonas reinhardtii pgr5 pgrl1 double mutant and respective single mutants. Under medium light conditions, the pgr5 exhibited the highest performance and produced about eight times more hydrogen than the wild type, making pgr5 one of the most efficient hydrogen producer reported so far. The pgr5 pgrl1 double ...

Natural ageing has a major influence on the properties of paper, while light, heat, and humidity are environmental influences that most disrupt stability paper. This research focuses changes in straw-containing papers caused by accelerated ageing. The were made laboratory mixing straw pulp with recycled fibers different weight ratios artificially aged dry-heat treatment (thermal oxidation) UV r...

We present an empirical method for estimating the underlying redshift distribution N(z) of galaxy photometric samples from photometric observables. The method does not rely on photometric redshift (photo-z) estimates for individual galaxies, which typically suffer from biases. Instead, it assigns weights to galaxies in a spectroscopic subsample such that the weighted distributions of photometri...

In this work the performance of a wavelength division multiple access (WDMA) system with direct detection receiver is investigated. For this purpose, the probability of error in a WDMA network with OOK modulation considering crosstalk, ISI, photo detector noise and thermal noise is calculated and the effect of each on system performance is investigated. The system performance in presence of PIN...

A capillary electrophoresis method was used for assay of some degradation products of carvedilol. The optimized parameters were as; running buffer 80 mM acetate dissolved in methanol/ethanol mixture (65:35 v/v), applied voltage of 19 kV, temperature is 20 ºC and the wavelength range of 200-350 nm. The results indicate that the proposed CE method could effectively separate carvedilol from its de...

Paraloid-Mg(OH)2 nanocomposites were synthesized via sonochemical method. Nanostructures were characterized by XRD and SEM. Thermal stability behavior of paraloid filled with magnesium hydroxide was investigated by thermogravimetric analysis (TGA). The influence of Mg(OH)2 nanostructures on the flame retardancy of the paraloid matrix was studied using UL-94 analysis. Our r...
