−The purpose of this investigation was to enhance the dissolution rate of loratadine using polyethylene glycol 6000 (PEG) solid dispersions (SDs). The solubility behavior of loratadine in the presence of polyethylene glycol 4000 and polyethylene glycol 6000 in water showed linear increase with increasing concentrations of PEG, indicating AL type solubility diagrams. SDs of loratadine with PEG 6...

Selective catalytic reduction (SCR) technique has been widely used for the abatement of the nitrogen oxides (NOX) emissions from diesel engines for decades. The urea-water solution (UWS) spray over the exhaust gases of diesel engines is one of the important methods used for exhaust after-treatment systems. The urea water solution is extensively injected in the upstream of the catalyst to genera...

The current study investigates capillary-fed boiling of water from porous sintered powder wicks used in emerging high-effective-conductivity vapor chamber heat spreaders intended for management of hot spots with heat fluxes exceeding 500 W cm . Characterization of 1 mm thick wicks composed of 100 lm sintered copper particles is performed in a test facility which replicates the capillary feeding...

© Appl. Rheol. 15 (2005) 390–397 Abstract: We report on the design and implementation of an evaporation blocker for cone-plate and plate-plate geometries. In addition to minimizing sample evaporation by trapping the saturated vapor inside a sample chamber, an important feature of the evaporation blocker is the suppression of solvent transport through condensation. Validation tests with DI-water...

the aim of this study was to prepare liposomes of acyclovir (acy) by thin layer evaporation (tle) and reverse phase evaporation (rev) methods. twenty-seven batches of liposomes from each method were prepared using technique of three variables at three levels (33) factorial design. drug/lipid (molar ratio), hydration volume and hydration time were considered three independent variables in tle me...

effect of seed priming on germination and seedling growth of sesame investigated under controlled conditions. the primed seeds with znso4 had the maximum germination percentage whereas the highest germination rate was observed in hydro-primed seeds. the treated seeds with peg showed the best growth of the seedlings and rootlet. the complementary field experiment was conducted to evaluate the ef...

We propose a simple scheme to estimate surface evaporation over large heterogeneous areas using remote sensing observations. Our approach is based on a relationship between easily measured surface parameters (e.g. radiometric surface temperature) and a surrogate for effective surface resistance. Preliminary results, using remotely sensed data sets from AVHRR NOAA-14 over the Southern Great Plai...

Hawking evaporation of black holes in the early Universe is expected to copiously produce all kinds particles, regardless their charges under Standard Model gauge group. For this reason, any fundamental particle, known or otherwise, could be produced during hole lifetime. This certainly includes dark matter (DM) particles. paper improves upon previous calculations DM production from primordial ...
