The present study attempts to introduce a method of statistical downscaling with a synoptic view. The precipitation data of Golestan Province has been used for the years 1971 to 2010. Employing multivariable regression, this study models the precipitation gauges in the station scale, by making use of 26 predicting components of model HadCM3, on the basis of two A2 and B2 scenarios. However, the...

The purification procedure of Clostridium perfringens type A enterotoxin has been improved. The cell sonic extract was precipitated twice with ammonium sulfate, first 40% saturated to concentrate the enterotoxin and then 15% saturated. The two precipitations were followed by gel filtration on Sephadex G-100. The enterotoxin appeared to be homogeneous on 7% polyacrylamide gel electrophoresis aft...

Description: BOTOX COSMETIC (Botulinum Toxin Type A) Purified Neurotoxin Complex is a sterile, vacuum-dried purified botulinum toxin type A, produced from fermentation of Hall strain Clostridium botulinum type A grown in a medium containing casein hydrolysate, glucose and yeast extract. It is purified from the culture solution by dialysis and a series of acid precipitations to a complex consist...

Stromatolites are the oldest recognized fossil recordings of life on Earth. Therefore, their study them represents one most interesting topic that investigates physio-chemical environmental conditions (formations and precipitations) at which stromatolites formed. This work deals with rare earth elements (REEs) geochemical characteristics redox-sensitive trace behavior newly formed in Salda Lake...

Abstract The nanometer-scale (nano-scale) microstructural evolution in an additively manufactured Re-free Ni-based superalloy, with single crystal compositions, is investigated through field emission scanning electron microscopy, transmission and atom probe tomography. We find that nano-scale primary ?? precipitation occurs the fine as-built microstructure, leading to exceptional microhardness ...

NDT is mainly discussed as an engineering technology to detect, classify and size material imperfections, called material defects. Lattice defects and microstructure inhomogeneities like vacancies, dissolved atoms dislocations and precipitations are normally not discussed as defects but they are influence parameters which mainly predict the macroscopic properties, the physical properties as wel...

The water resources of Côte d’Ivoire are very much used for water drinking supply of populations, breeding and also for the agriculture. But the abundance of this resource knew disturbances as from the years 1968 to 1970. These upheavals resulted in a fall of precipitat ions of 12.4% to 31.4% and flows which varied from 31.40% to 55.4%. The projections carried out on the hydro-climate parameter...

Abstract The Precipitations conditions having special attention in the last decade due to their impact on human health, ecosystems and other aspects such as agriculture, hydrology. ECMWF ERA-Interim 15-hourly (00 15 UTC) total precipitations a 1° x grid covering Iraq, from 29° N 38° 39° W 48° E, with of 10 by cells, was used. At each point, extremes were defined those events which above 90 th p...

A technique was developed for algal toxicity assays. Algal communities obtained from several sewage treatment plants and surface waters were the test specimens. The toxicant used was zinc acetate The techniques that were developed are relatively simple, rapid, and precise. Algal responses to toxicants were measured by changes in oxygen production, and two types of responses were observed. The v...
