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 ...

Abstract. To study sea-derived gaseous amines, ammonia, and primary particulate aminium ions in the marine atmosphere of China's marginal seas, an onboard URG-9000D Ambient Ion Monitor-Ion Chromatograph (AIM-IC, Thermo Fisher) was set up on front deck R/V Dongfanghong-3 to semi-continuously measure spatiotemporal variations concentrations atmospheric trimethylamine (TMAgas), dimethylamine (DMAg...

The ability of photochemical models to predict observed coastal chlorine levels and their corresponding effect on ozone formation is explored. Current sea-spray generation functions, a comprehensive gas-phase chlorine chemistry mechanism, and several heterogeneous/multiphase chemical reactions considered key processes leading to reactive chlorine formation are added to an airshed model of the S...

The standard model for dealing with turbulence and air-sea interactions has three components: (1) The ocean surface can be characterized by its temperature and aerodynamic roughness. (2) Given (1) we can use the wind speed and air temperature/humidity to determine the air sea fluxes. All relevant properties of the profiles of the mean and turbulent fields in the surface layer can them be comput...

The macro characteristics and configurations of induced shock waves of the supersonic sprays are investigated by experimental methods. Visualization study of spray shape is carried out with the high-speed camera. The macro characteristics including spray tip penetration, velocity of spray tip and spray angle are analyzed. The configurations of shock waves are investigated by Schlieren technique...

BACKGROUND Spray boom systems, an alternative to the predominantly-used spray guns, have the potential to considerably improve crop protection management in glasshouses. Based on earlier experiments, the further optimization of the deposits of a medium spray quality extended range flat fan nozzle type using easy adjustable spray boom settings was examined. Using mineral chelate tracers and wate...

Significant progress has been made in the area of upper ocean responses and air-sea interactions during the passage of tropical cyclones (TC) since the first edition published in 1992. In terms of the upper ocean impacts on intensity, considerable attention has focused on the three-dimensional cold wake structure and the negative feedback due to ocean mixed layer cooling by shear-induced vertic...
