BACKGROUND Desflurane is known to produce high concentrations of carbon monoxide (CO) in desiccated sodalime or Baralyme (Allied Healthcare Products, St. Louis, MO). Desiccated absorbents without strong bases like potassium hydroxide or sodium hydroxide are reported to produce less or no CO at all. The purpose of this study is to compare the concentration of CO in an anesthesia circuit for desf...

During the last half-century, CO2 concentration in world’s atmosphere has increased from 310 p.p.m. to over 380 This is due widespread usage of fossil fuels as a main source energy. Modeling forecasts have shown that this trend will continue rise and reducing emissions challenging task for multi-stakeholders, including research institutions. The UN Climate Change Conference Glasgow (COP26) stre...

In the absorption step of the fluorescent treponemal antibody-absorption (FTA-ABS) test (USPHS, 1969) sorbent is used to circumvrent so-called natural antiTreponema pallidum (Tp) reactivity present in a significant proportion of presumed nonsyphilitic individuals (Hunter, Norins, Falcone, and Stout, 1968). It has been postulated that the natural reactivity may be stimulated by nonpathogenic, sa...

We demonstrate Ni–N/C is an effective electrocatalyst for the direct conversion of captured CO 2 in monoethanol amine-based aqueous absorbents showing high faradaic efficiency (78%) and its selectivity maintained various amine solvents.

introduction ensiling is one of the common preserving methods for forage or other organic materials. in this method, organic matters were preserved by proving an aerobic condition and then by reducing the ph with increasing acids production (mainly lactic acid). some circumstances like enough soluble carbohydrates, low buffering capacity and appropriate dry matter concentration are needed in en...
