In a double-blind group sequential trial the efficiency of an oxytocin nasal spray in enhancing lactation was studied during the first five days after delivery in women who had given birth prematurely. The cumulative volume of breast milk obtained between the second and fifth days after delivery was 3.5 times greater in primiparas given oxytocin than in primiparas given placebo. There was no si...

Ipratropium bromide is a white to off-white crystalline substance. It is freely soluble in lower alcohols and water, existing in an ionized state in aqueous solutions, and relatively insoluble in non-polar media. Ipratropium bromide nasal solution, 0.06% is a metereddose, manual pump spray unit which delivers 42 mcg ipratropium bromide (on an anhydrous basis) per spray (70 mcL) in an isotonic, ...

The present study investigated the effect of operating parameters of a laboratory spray dryer on powder characteristics, in order to optimise the production of trehalose and raffinose powders, intended to be used as carriers of biomolecules for inhalation. The sugars were spray dried from 80:20 methanol:n-butyl acetate (v/v) solutions using a Büchi Mini Spray dryer B-290. A 2(4) factorial desig...

rotary atomizers are commonly used in spray dryers to atomize feed. one destructive effect of wheel rotation is the creation of a vacuum inside the wheel that conducts hot air from the chamber into the wheel and can lead to atomizer blockage and an explosion. the present work determined the air-pumping characteristics of a rotary atomizer with a 50 mm wheel diameter. the vacuum pressure and pow...

To help understand the complex fuel spray combustion phenomena in modern diesel engine using high injection pressure, a fuel injection test bench and a constant volume combustion chamber were developed and demonstrated in this study for diesel spray diagnostics. Both facilities are significant when linking between spray injection and combustion dynamics and engine performance. This link is impo...

This study describes methods developed for reliable quantification of sizeand element-specific release of engineered nanoparticles (ENP) from consumer spray products. A modified glove box setup was designed to allow controlled spray experiments in a particle-minimized environment. Time dependence of the particle size distribution in a size range of 10–500 nm and ENP release rates were studied u...

the increase of cell temperature with increased irradiance is probably the mostsignificant disadvantage of using photovoltaic modules equipped with booster reflectors. the aimof this study is to investigate the possibility of improving the performance of a photovoltaic waterpumping system by using a booster reflector and to keep the temperature of pv panels at a lowlevel by cooling pv panels wi...

Numerous drift reduction adjuvants and spray deposition aids are available to applicators of crop production and protection chemicals. Performance of many of the newly introduced drift control adjuvants has not been well documented for aerial application. Since there are no product labeling or efficacy regulations for these adjuvants, applicators must rely on experience or information in the te...
