Solid lipid nanoparticles of atovaquone (ATQ-SLN) were prepared by high shearhomogenization method using tripalmitin, trilaurin, and Compritol 888 ATO as the lipidmatrices and Phospholipon 90H, Tween 80, and poloxamer 188 as the surfactants. Optimizationof the formulations was conducted using 6 sets of 24 full-factorial design based on fourindependent variables that were the number of homogeniz...

A study of the kinetic analysis of total lead from spent Car battery ash by hydrochloric acidleaching has been examined. The physico-chemical analysis of the ash powder was carried outby the Inductively Coupled Plasma-Mass Spectrometry (ICP-MS) and X–ray diffraction (XRD).The effects of the acid concentration, temperature and particle size on the rate of battery ashdissolution have been investi...

‎The problem of two-phase MHD boundary layer flow, heat and mass transfer over a stretching sheet with fluid-particle suspension and thermal radiation has been studied. The effect of mass transfer in dusty fluid over a stretching sheet is considered for the first time. The governing equations are reduced to a set of non-linear ordinary differential equations under suitable similarity transforma...

The nanoparticle transportation and Brownian diffusion in planar jet flow is simulated via large eddy simulation in this work. To thorough compare the Brownian diffusion with different particle size, we computed three particle diameter dp = 1 nm, 10 nm and 50 nm in one simulation process simultaneously. The numerical results showed that at the flow developing stage, the particle mass concentrat...

The suspended particle assemblage in complex coastal waters is a mixture of living phytoplankton, other autochthonous matter, and materials of terrestrial origin. The characterization of suspended particles is important for understanding regional primary productivity and rates of carbon sequestration, the fate of anthropogenic materials released to the coastal environment, as well as its effect...

In this study, alkaline colloidal silica was prepared by titration of an alkaline solution such as sodium silicate with silicic acid in constant range of pH  .This constant range of pH was achieved by using concentrated soduim silicate solutions as pH adjusting solutions during titration.The sodium silicate solutions  having a variety of...

AIM Recent data suggests that LDL particle concentration, as determined by Nuclear Magnetic Resonance (NMR) spectroscopy, may be associated with cardiovascular risk. We sought to determine the effect of randomization to pravastatin therapy on LDL particle concentration-NMR, among a primary prevention population. METHODS AND RESULTS LDL particle concentration-NMR, LDL size-NMR, and standard ch...

In this paper airflow, nano-and micro-particle motions in an aerodynamic particle beam focusing system consisting of several lenses, a nozzle and the downstream chamber, was studied. A three-dimensional numerical simulation for the system was presented and the compressible airflow and thermal conditions in the aerodynamic lens system were evaluated. Dilute particle concentration was assumed so ...

in this study the effects of mesolites from moghueieh region and their particles size on performance, blood biochemical parameters and nutrient digestibility in broiler chickens were evaluated. the experiment was conducted on a completely randomized design with three treatments: without mesolite (control) and with fine particle mesolite (passed of 1 mm sieve and stay in 0.225 mm sieve) or large...
