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...

Pothole formation and development may be influenced by joint sets and other heterogeneities within bedrock, as well as by hydraulics. Previous research indicates that most potholes found in rivers of the mountainous Spanish Central System exhibit preferred orientations associated with dominant joints and correlate more strongly with variations in substrate resistance than with hydraulics. Weath...

AVS2 is a new generation video coding standard developed by the AVS working group. Compared with the first generation AVS video coding standard, known as AVS1, AVS2 significantly improves coding performance by using many new coding technologies, e.g., adaptive block partition and two level transform coding. Moreover, for scene video, e.g. surveillance video and conference vid⁃ eo, AVS2 provided...

We present a model of early lexical acquisition. Successful word learning builds on pre-existing, self-organising categorisation capacities and through joint attentional events between the infant and the caregiver. Our model successfully accounts for the emergence of a lexical constraint, taxonomic responding, as well as a steep increase in the rate of acquisition of words, without any need for...

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 ...

Antioxidants for facial skin care would be better formulated in a topical form because the active substances will interact longer with skin. Indonesia is known its wealth of natural ingredients that are useful as antioxidants. Research related to has been widely carried out and good content The antioxidant herbal plants secondary metabolites, namely flavonoids, alkaloids, phenolic compounds, ca...

Five field populations of Musca domestica L. collected in poultry farms were bioassayed in order to detect possible resistance to the larvicide cyromazine in Brazil. The concentrations used were 0, 0.5, 0.1, 0.2, 0.4, 1, 2, 4 and 8 ppm. Three populations (Petrópolis, RJ, Montes Claros, MG and Promissão, SP) were resistant, while the other two populations (Ibiuna, SP and Monte Mor, SP) were more...

Introduction: Peripheral intravenous (IV) cannulation are routine procedures in emergency department (ED) admissions. Vapocoolant sprays have a potential advantage over other topical agents.We aimed to see how effective vapocoolant spray was reducing pain during versus control group this study. Materials and Methods: This is prospective, randomized study consisting of patients who were admitted...
