The current study focused on the formulation, physicochemical characterization, and antibacterial susceptibility testing of inhalable spray dried powders containing ciprofloxacin (CIP) polymyxin B sulfate (PMB). CIP nanosuspensions with an average particle diameter 435.9 ± 9.3 nm were initially obtained using wet-milling protocol subsequently co-spray PMB solutions to yield dry powders. Powder ...

the spray characteristics of the fuel greatly influence emissions from diesel engines. spray development plays a vital role in improving the combustion and emission characteristics of fuel because it directly affects the air- fuel mixture formation. the spray characteristics of fuel mainly depend on fuel injection process, fuel density, fuel viscosity, ambient pressure and temperature. among th...

the influence of ammonium nitrate (amn) on antagonism of sodium bicarbonate (nahco3) in spray tank of glyphosate (roundup®, 41% sl) and nicosulfuron (cruse®, 4% sc) on barnyard-grass [echinochloa crus-galli (l.) p. beauv.] and velvetleaf (abutilon theophrasti medicus.) control were examined in greenhouse studies as a factorial arrangement of treatments 6×2 based on a completely randomized desig...

Long-term impacts of alternative citrus nitrogen and water management practices implemented at grower cooperator sites on the Central Florida Ridge were modeled using the nitrogen component of the Leaching Estimation and Chemistry Model (LEACHN). A bromide tracer test was conducted at one representative cooperator site to parameterize and validate the model. Following validation, 50-year simula...

piroxicam, an anti-inflammatory drug, exhibits poor water solubility and flow properties, poor dissolution and poor wetting. consequently, the aim of this study was to improve the dissolution of piroxicam. microparticles containing piroxicam were produced by spray drying, using isopropyl alcohol and water in the ratio of 40:60 v/v as solvent system, and spray chilling technology by melting the ...
