The formulation of hydrophobic drugs for oral drug delivery is challenging due to poor solubility, poor dissolution and poor wetting of these drugs. Consequently, the aim of this study was to improve the dissolution of a model poorly water soluble drug, ibuprofen. Microparticles containing ibuprofen were produced by spray drying and spray chilling technology in the absence/presence of a ...

total of 270 quail fertile eggs were set in hatchery. experimental groups including: negative control (neither received probiotic treatment nor challenged by salmonella), positive control (challenged by salmonella but not probiotic treatment) and 7 in hatchery administration methods: in ovo injection, spray, oral gavage, cloacal drinking (cloacal inoculation), cloacal drinking – in ovo injectio...

BACKGROUND Steinernema carpocapsae Weiser, an entomopathogenic nematode (EPN), is a potential biological control agent for the cabbage moth (Mamestra brassicae L.). This research aimed to identify a suitable spray application technique, and to determine whether yeast extract added to an EPN spray has an attracting and/or a feeding stimulant effect on M. brassicae. The biological control capabil...

OBJECTIVE To investigate the influence of maintenance spray on resin bonding to dentin. MATERIALS AND METHODS The crown of extracted, caries-free human molars was transversally sectioned with a model trimmer to prepare the dentin surfaces from mid-coronal sound dentin, and then uniformly abraded with #600 silicon carbide paper. The dentin surfaces were randomly divided into three groups: oil-...

A theoretical and experimental study of the dense-spray region of pressure-atomized nonevaporating sprays is described, emphasizing effects of ambient gas density in the atomization breakup regime. Mean liquid volume fraction distributions were measured for 9.5 mm diameter water jets in still air at pressures of 1-8 atm. Mixing was strongly affected by the gaslliquid density ratio and the degre...

The objective of this study is taken to realize pesticide precision spray of fruit trees and the other crops and reduce the deposition losses outside the canopy when the real time sensing technology was used in the pesticide target spray. In this paper the Pesticide solution deposition distribution experiments were conducted with two different volume median diameter (VMD) hollow cone nozzles fi...

Screwworm flies, Cochliomyia hominivorax (Coquerel), were fed on honey and spray dried egg product; honey, molasses, and spray dried egg product; honey and spray dried meat protein; as well as on a control diet of honey and horsemeat, which is the standard diet used for screwworm adult colony in the mass-rearing facility. In general, the weight of eggs laid by females fed on the diet of spray d...

A method to aim toward crop-rows was put forward for spray control in this article. At first, the image of crops captured by a CCD camera was passed on computer, then crops were segmented from background by obtaining H value and its binary image was obtained by means of OSTU. Finally, the center line of crop-row was regressed by Hough transform after the binary image was morphologically eroded....

BACKGROUND Untreated immunization pain causes undue distress and contributes to underimmunization through physician, and possibly parental, resistance to multiple simultaneous injections. OBJECTIVE To compare the efficacies of two pain management methods in reducing immediate immunization injection pain and distress in school-aged children. DESIGN A randomized, controlled clinical trial of ...

effects of drought stress and chemical treatments was studied on growth and developmental traits of four barley cultivars using a split- split plot design (rcbd) in agricultural research farm, kerman university in 2013-14. main plots consisted of irrigation (control and drought stress after flowering), sub-plots consisted of four barley cultivars (ʻnosratʼ, ʻafsalʼ, ʻyousofʼ and ʻuh12 lineʼ) an...
