BACKGROUND The purpose of this study was to examine retinal recovery processes to pographically by the application of three flash sequences with specific interstimulus intervals. METHODS Twelve healthy subjects underwent multifocal electroretinography with a light-emitting diode stimulator. Every flash sequence consisted of three flashes with 25 msec between the first and the second flash and...

the reaction kinetics of the isomerization 3,4-dichlorobutene-1 to 1,4-dichlorobutene-2 was investigated by using gas-liquid chromatography method in the presence of fe2o3/mgo as solid catalyst in the temperature range 25-55°c. fe2o3/mgo has been prepared by the support saturation method, tested in the isomerization of 3, 4-dichlorobutene-1 into 1, 4-dichlorobutene-2. this catalyst shows a high...

the kinetics and mechanism of the reaction of 5-nitro-1h-benzo[d] imidazole to produce 6-nitro-1h-benzo[d] imidazole was studied by employing hybrid meta-density functional theory. mpwblk/6-31+g** level calculations were carried out to obtain energies and optimize the geometries of all stationary points along the pes, and determine the harmonic vibrational frequencies. two transition states (ts...

The static recrystallization/grain growth kinetics of the AZ31 (Mg-3Al-1Zn, wt%) alloy were investigated employing Vickers microhardness and electron backscatter diffraction (EBSD) measurements. was subject to a hot-rolling for 70% thickness reduction then annealed at various temperatures (150°C, 250°C, 350°C) from 5 min 24 h. First, recrystallization analysed by means Johnson-Mehl-Avrami-Kolmo...

Bioleaching was used to mobilize Cu, Zn and Ni from waste printed circuit boards (WPCBs) and eliminate hazardous metal species from these wastes. Pulp density (PD) and medium culture are two effective factors which have been optimized in this paper. The bacteria Acidithiobacillus ferrooxidans (A. ferrooxidans) and Acidithiobacillus thiooxidans (A. thiooxidans) and their mixture were grown and a...

The ability to recover up-to-date architectural information from existing software artifacts is key to effective software maintenance, reengineering and reuse. Although architecture recovery can be facilitated with the help of current reverse engineering techniques and tools, many issues remain to be properly addressed, particularly regarding recovery of runtime abstractions (e.g., clients, ser...
