A variety of different isoforms of voltage-sensitive Na+ channels have now been identified. The recent three-dimensional analysis of Na+ channels has unveiled a unique and unexpected structure of the Na+ channel protein. Na+ channels can be classified into two categories on the basis of their amino acid sequence, Nav1 isoforms currently comprising nine highly homologous clones and Nax that poss...

The removal of the non-steroidal anti-inflammatory drug (NSAID) Naproxen (NAX) in water by hydroxyl radicals (•OH) was performed electrochemical advanced oxidation processes either with Pt or BDD anodes and a 3D carbon felt cathode. degradation NAX (•OH vs electrolysis time) well fitted to pseudo-first-order reaction rate kinetic. detected intermediates (aromatic compounds carboxylic acids) wer...

The spin-lattice relaxation time T\ of 2 , N a N M R in dehydrated zeolite NaY has been measured from 26 to 300 K. The magnetization recovery curve is not single-exponential at all measured temperatures and 1 increases in proportion to the square of temperature above 200 K. The result is analyzed with a theory of the Raman process based on covalency. The value of T\ is compared with that of NaX...

Herein, optimization of zeolite NaA/NaX synthesis conditions in order to obtain the final product with high surface area and pore volume was investigated. An optimal condition 5 days aging time crystallization 9 h co-addition cetyltrimethylammonium bromide (CTAB) heptane. All those provided mixed phase between NaA NaX, addition organic phases improved synthesized zeolite. The role CTAB heptane ...

Sulfur-containing organic and inorganic compounds are the main harmful component of natural gas oil, as well products their processing. Since sulfur have acidic properties, content leads to corrosion technological parts in production processes. The hydrogen sulfide transported should not exceed 20 mg/m3. In Uzbekistan, motor vehicles run mainly on liquefied gas. Sulfur corrode cylinders, result...
