Theoretical models indicate the possibility of diagnosing presence and conductivity hydraulic fractures in reservoirs permeability order milli Darcy by means an acoustic TV set, which is a cylindrical probe length several meters with generator impulse signals pressure sensors. It suggested to generate signal fluid, filling gap between body outer wall borehole. supposed that generated fluid loca...

The aim of this study was to determine aztreonam (ATM) membrane permeability using Calu-3 cells and its plasma and pulmonary epithelial lining fluid (ELF) pharmacokinetics in rats after intratracheal nebulization and intravenous administration (15 mg · kg(-1)). ATM exhibits low Calu-3 permeability (0.07 ± 0.02 × 10(-6) cm · s(-1)), and a high area under the ELF/unbound plasma concentration time...

results gelatin films exhibited good tensile strength and elongation at break, water solubility, swelling, and water vapor permeability. incorporation of tam into the gelatin films caused a significant decrease in tensile strength and swelling, and a significant increase in elongation at break, water solubility, water vapor permeability and whiteness of the films. gelatin films exhibited low an...

the topical delivery of non-steroidal anti-inflammatory drugs (nsaids) such as ibuprofen has been explored as a potential method of avoiding the first pass effects and the gastric irritation, which may occur when used orally. ibuprofen is formulated into many topical preparations to reduce the adverse effects and simultaneously avoid the hepatic first-pass metabolism as well. however, it is dif...

Over 90% of the global hydrate resources are stored in very-low-permeability clayey silt reservoirs. The low permeability significantly restricts efficiency gas and water flow into production well. To enhance low-permeability reservoirs, high-pressure rotating jets (HPRWJ) technology is proposed to construct near wellbore artificial fractures (NWAFs) HPRWJ avoid risks hydraulic fracturing as we...
