Injection of sulfate ions into the cement matrix with water by wet spraying due to high moist in environment is reason deterioration acceleration and durability decrease time. The effects introduction redispersible polymers (RP) calcium formate on increasing decreasing effect caused were studied. Vinyl-acetate/versatate, vinyl-acrylic copolymer mixed nine separate mixtures at a concentration ad...

An investigation of the natural products chemistry of the brown alga Sargassum asperifolium from the red sea yielded a new steroidal metabolite, 24-vinyl cholest-4-ene-24-ol-3-one, saringosterone (3), a known steroidal metabolite, 24-vinyl cholest-5-ene-3b,24-diol, saringosterol (4), and known diterpene with a hydroazulene skeleton, dictyone (1). The identification of the isolated metabolites w...

   Repeated oral administration of mexazolam, an anti-anxiety agent, may cause adverse effects such as gastric disturbance, drowsiness, and ataxia due to transiently high blood levels. Transdermal administration would avoid the systemic side effects and gastric disorders after oral administration. We have developed a matrix using ethylene-vinyl acetate (EVA), a heat-processible and flexible mat...
