Solubilization technology At present, most of the methods for improving the solubility of drugs on the market are mainly drug solubilization methods, including ?pH adjustment method: suitable for some weakly acidic and weakly basic drugs, by adjusting the pH value to increase the solubility of the drug; ...
Following 20-min runs, with an equivalent distance of 500 m travelled by water particles, a number of statistically significant changes in the stormwater chemistry were observed: (i) pH of all the simulated stormwaters increased in the concrete pipe (from 7.0–7.3 to 8.1–9.3), (ii) turbidity decreased in two stormwaters with sediments (SW2 and SW3) in concrete and ...
A pH simulator consisting of an efficient numerical solver of a system of nine nonlinear equations was constructed and implemented in the modeling software MATLAB. The pH simulator was integrated in a granular biofilm model and used to simulate the pH profiles within granules performing the ...
The experiments were conducted using NaHCO3 buffered synthetic water samples with different characteristics (i.e. pH, phosphate, stagnation time) simulating with water distribution systems. The results showed that Fe(II) ions significantly reduced HAAs formation in different reaction systems at a 95% confidence level. In control water systems, ...
The cements were evaluated regarding the pH-variation in simulated body fluid (SBF). Further, the biocompatibility of the cement with human mesenchymal stem cells (MSC) was studied in vitro and eventual inflammation properties studied in vivo, after subcutaneous material injections in rats. A larger pH decrease was seen for the conventional ...
In vitro studies were used to determine the effects of simulated gastric fluid (SGF) and bile salts on the viability of free and encapsulated phage. Free phage Felix O1 was found to be extremely sensitive to acidic environments and was not detectable after a 5-min exposure to pHs below 3.7. In contrast, the number of microencapsulated phage decreased by 0.67 log ...
The precipitation of heavy metals from the simulated wastewater was investigated under varing conditions of pH, temperature, and heavy metal concentrations. ...
