wheat straw, as an animal feed source, is of a low nutritional value, which can be enriched through a process of urea treatment. this process is the rewetting of the straw to the point of increasing its moisture content up to 30-50 percent using urea solution. the conventional method of treatment is a laborious, tedious and time consuming task. to facilitate this process some of these operation...
changes of hydrodynamic parameters in microchannel branches affect the suspended biological samples in blood. to prevent denaturation and hemolysis, we have numerically investigated the effect of divergence angle on shear rate and velocity at branch entrance (discharge rate), under electroosmotic flow. in such flow, hydrodynamic properties are also affected by zeta potential at the microchannel...
The present study investigated the effect of operating parameters of a laboratory spray dryer on powder characteristics, in order to optimise the production of trehalose and raffinose powders, intended to be used as carriers of biomolecules for inhalation. The sugars were spray dried from 80:20 methanol:n-butyl acetate (v/v) solutions using a Büchi Mini Spray dryer B-290. A 2(4) factorial desig...
The most common approach to generating dense optical ow elds embeds the intensity constancy constraint within a multi-resolution framework using a Laplacian pyramid. Such a framework, in which motion estimates at one scale are used to seed more accurate estimation at ner resolutions, has the potential ability to capture large motions, reducing the likelihood of aliasing. This approach, however,...
Electro-osmotic pumping (EOP) theory and its characteristics (transport numbers, brine concentration, current density, current efficiency, electro-osmotic coefficients, etc.) of Selemion AMV and CMV ion-exchange membranes were studied. The brine concentration increased with increase in current density and feed water concentration. Current efficiency was nearly constant in a wide range of curren...
A preceding study analysed how the topology of network motifs affects the overall rate of the underlying biochemical processes. Surprisingly, it was shown that topologically non-isomorphic motifs can still be isodynamic in the sense that they exhibit the exact same performance rate. Because of the high prevalence of feed-forward functional modules in biological networks, one may hypothesize tha...
A spraying evaporation system applied to brine disposal is reported, which is mainly used for disposing the brine with concentration more than 100,000 mg/L. A computational fluid dynamics (CFD) simulation has been carried out to study the brine droplet evaporation and diffusion process in high temperature air flow. A discrete-phase model in spraying evaporation system is developed and a simulat...
This investigation was carried out to determine the effect of feeding strategies on growth performance, biochemical parameters, and hematological indices in male rainbow trout (Oncorhynchus mykiss) broodstocks. For this purpose, 45 broodstocks with 475.55 ± 54.24 g (mean ± S.D) were divided into three treatments and fed at satiation, restricted feeding (50% of satiation limit), and starvation...
This research presents an experimental analysis of a counter flow spray drying process using water and skim milk as feed. The study was performed by examining the droplet size distribution sprays temperature profiles in dryer. influence air inlet temperature, mass rate, feed on temperatures dryer evaluated. evaporation deposition zones were found to be highly dependent size. obtained results sh...
Rapid, in situ, and label-free chemical analysis in microfluidic devices is highly desirable. FT-IR spectroscopic imaging has previously been shown to be a powerful tool to visualize the distribution of different chemicals in flows in a microfluidic device at near video rate imaging speed without tracers or dyes. This paper demonstrates the possibility of using this imaging technology to captur...
