in this study, sio2 nanoparticles were successfully synthesized via sol-gel precipitation method and the effects of different parameters such as temperature, ethanol, ammonia and tetraethylorthosilicate (teos) contents based on water were investigated in a systematic way applying taguchi experimental design method. it was found that, among all the investigated parameters, ethanol as a co-solven...

We deployed autonomous particle-sensing SOLOPC floats more than eight times during five cruises, amassing almost 400 profiles of particle size (d490 mm) and abundance between the ocean surface and 100 m. The profiles consistently had subsurface maxima in particle volume. The median (by volume) equivalent spherical diameter for the particle distribution was 0.4–0.8 mm and increased with depth in...

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...

Complete diets for laying hens are usually offered in meal form. This form initially promotes the hens’ natural feed intake behavior and allows them to satisfy their pecking behavior. At same time, it can also cause difficulties, because consists of different particles is not a homogeneous unit. A mixture essential ensure that each hen flock meet its nutritional needs. If exhibits wide particle...

in suspension polymerization, particle size distribution of polymer is the outcome of dynamic equilibrium between the break up and coalescence phenomena. the rates of break up and coalescence and consequently polymerization stability depend on several parameters, the most important of which are type and concentration of stabilizer. in this study, the effects of type and concentration of stabili...

A study was designed to collect a database of Iowa feedlot rations for determination of effective neutral detergent fiber (NDF) in complete diets from fiber analysis and particle size determination of individual feed ingredients and compare this with particle size determination of mixed wet rations. Seventy-one beef finishing total mixed rations were collected by ISU Extension Beef Field Specia...
