Solar radiation homogenizers are multi-mirror devices that try to reshape the solar distribution coming from a concentrator, so that, after passing through homogenizer, light flux becomes as much evenly distributed possible. The optical behavior of these multi-reflective is complex and still ill-understood. geometry concentrator defines features concentrated then characteristics particular homo...

2 From its very genesis APV has maintained an impeccable reputation for excellence worldwide. That standard is perpetuated in the field of homogenization and high pressure pumps. It's a tradition that dates back to our invention of the homogenizer in the early 1900's. That desire to excel in saving our customers is demonstrated today through innovative design, precision, engineering, quality ma...

among 14,102 patients admitted in teaching hospitals of the isfahan medical school, whose records were studied, 2,122 or 15.4% of patients had high blood pressure. the most common reason for blood pressure in this group was diseases of the kidney and for those, glomerolonephritis and pilonephrititis were important causes. among patients under 30 years old, high blood pressure was twice as commo...

Cellulose nanofibrils were prepared by mechanical fibrillation of never-dried beech pulp and bacterial cellulose. To facilitate the separation of individual fibrils, one part of the wood pulp was surface-carboxylated by a catalytic oxidation using (2,2,6,6-tetramethylpiperidin-1-yl)oxyl (TEMPO) as a catalyst. After fibrillation by a high pressure homogenizer, the obtained aqueous fibril dispers...

The droplet deformation in dispersing units of high-pressure homogenizers (HPH) is examined experimentally and numerically. Due to the small size common homogenizer nozzles, visual analysis transient generation usually not possible. Therefore, a scaled setup was used. determined quantitatively by using shadow imaging technique. It shown that influence stresses on droplets caused laminar extensi...
