A novel mechanical method, for studying acutely isolated maturing Drosophila central neurons, has been developed. Electrophysiological experiments have been carried out to assess the quality of these acutely dissociated neurons. The mechanically dissociated Drosophila central neurons were divided into three categories depending on their size and morphological features. Four types of whole-cell ...
The enzyme, aryl acylamidase, was characterized in propanil-susceptible and propanil-resistant barnyardgrass with respect to kinetic parameters, the effects of inhibitors, and the levels of activity in darkand light-grown tissues. The enzyme reaction in the resistant tissue preparation proceeded linearly with time over a 5 h time course, while activity in the susceptible tissue preparation was ...
We report the preparation and new insight into photophysical properties of luminescent hydroxypyridonate complexes [M(III)L](-) (M = Eu or Sm) of the versatile 3,4,3-LI(1,2-HOPO) ligand (L). We report the crystal structure of this ligand with Eu(III) as well as insights into the coordination behavior and geometry in solution by using magnetic circular dichroism. In addition TD-DFT calculations ...
A set of Au/C catalysts for the gas phase hydrochlorination of acetylene to vinyl chloride monomer were prepared using a range of strong acids as impregnating solvents and varying the preparation drying temperature. The most active catalyst is the material prepared using aqua regia as solvent with an intermediate drying temperature of 140 C. The effects of the catalyst preparation parameters on...
This work aims to study the photodegradation of Direct Blue 199 dye. The investigation was performed using titanium dioxide-based films immobilized on a polymethyl methacrylate (PMMA) polymer, by a promising low coast technique. The characterization of the films by X-ray diffractometry, fourier transform infrared spectroscopy, scanning electron microscopy, UV-Visible transmittance, and fluo...
Methods for preparation of nanocomposites modified detonation nanodiamonds (DND) with metallic palladium have been developed and their catalytic activity in the Suzuki-Miyaura cross-coupling reaction various media has studied. regeneration palladium-containing from mixture developed. The high is confirmed by kinetic analysis based on results chromatographic comparable to literature data about s...
In this note, we prove the generic Kobayashi volume measure hyperbolicity of singular directed varieties (X,V ), as soon as the canonical sheaf KV of V is big in the sense of Demailly.
In this study, the main objective is the preparation and the characterization of a modified Algerian bentonite based adsorbent by intercalation with hexadecyltrimethylammonium bromide (HDTMA). Natural and modified bentonites were characterized using thermogravimetric analysis (TGA), X-ray diffraction (XRD) and infrared spectroscopy (FTIR). The X-ray results indicate that the geometry of the int...
Toxicity has occurred in workers exposed to nickel dust or nickel carbonyl formed in refining. Increased risk of nasal and lung cancers was linked to occupational nickel exposure before current workplace safety standards were set. Activated carbon with nano holes used for removing contaminants in environment. The purpose of this work is preparation a new nano-absorber, GZ-BAKI-TAC-Ni-88, for th...
In this study, buccal mucoadhesive tablets of meloxicam were formulated for drug delivery as an alternative route. Direct compression method was applied for the preparation of tablets. Also, different polymers, including hydroxypropyl methyl cellulose (HPMC) 1000, 4000, and 10000, as well as carbopol 934p and carbopol 971p were used as the mucoadhesive polymer and retardant polymer. Thirteen fo...
