Lamotrigine is a substituted asymmetric triazine. It is a white to pale cream-coloured powder. It is slightly soluble in ethanol and chloroform, and very slightly soluble in water. The pKa of lamotrigine at 25°C is 5.7. Each Lamictal Dispersible/Chewable tablet also contains calcium carbonate, hydroxypropyl cellulose, aluminium magnesium silicate, sodium starch glycollate, povidone, saccharin s...

in this study the effects of plant growth regulators including; ga3 (0 and 50 mg/l) and ethephon (0 and 500 mg/l) were studied on the quality properties of two grape cultivars (perlette and yaghuti). at the harvest time, some physicochemical characteristics such as fruit cluster weight, fruit diameter, length, volume and l/d ratio, flesh firmness, fresh weight, ta, ph, tss and fruit color were ...

The molecular weight of the major glycoprotein from the human erythrocyte membrane is 29,000, of which 55% is carbohydrate and 45% is protein. The binding of sodium dodecyl sulfate to this glycoprotein is anomalous when compared to water soluble proteins and leads to migration rates in sodium dodecyl sulfate-polyacrylamide gels that cannot be interpreted in terms of molecular weight. Anomalous ...

effluent from ro (reverse osmosis) systems during recovery gradually becomes concentrated and supersaturated with soluble salts such as calcium carbonate (caco3), calcium sulfate (caso4), barium sulfate (baso4) and silica (sio2). thus we were looking for procedures to prevent precipitation of soluble salts on the membrane surface and decrease membrane permeability. therefore, recovery could be ...

Famotidine is a white to pale yellow crystalline compound that is freely soluble in glacial acetic acid, slightly soluble in methanol, very slightly soluble in water, and practically insoluble in ethanol. Each tablet for oral administration contains either 20 mg or 40 mg of famotidine and the following inactive ingredients: hydroxypropyl cellulose, hypromellose, iron oxides, magnesium stearate,...

to investigate the effect of salicylic acid (sa) on salinity tolerance of two sugar beet cultivars, this experiment was conducted as split factorial based on a randomized complete block design with three replications during growing seasons of 2012 and 2013 in research farm of shahid chamran university. the studied factors were three levels of sa (0 mm, 0.5 mm and 1 mm), two levels of salinity (...
