The object of research is the mode movement granules mineral fertilizers obtained in towers. subject effect physical and chemical properties granules, their size initial hydrodynamic parameters on speed tower. fertilizer industry characterized by high requirements for production fertilizers, which makes it promising to use granulation plants large unit capacity, tower production. resulting prod...

Previous in vitro studies have suggested that surfactant protein A (SP-A) may play a role in pulmonary surfactant homeostasis by mediating surfactant secretion and clearance. However, mice made deficient in SP-A [SP-A (-/-) animals] have relatively normal levels of surfactant compared with wild-type SP-A (+/+) animals. We hypothesize that SP-A may play a role in surfactant homeostasis after acu...

nf-κb pathway is a link between inflammation and cancer and is involved in cellular responses to different stimuli. gastrointestinal lumen is exposed to many inflammatory agents such as foods, free radicals and bacterial or viral antigens. the aim of the present study was to evaluate the possible role of nf-κb1in gastric adenocarcinoma. to detect the relative level of nf-κb1transcript, total rn...

The key feature of respiratory distress syndrome (RDS) is the insufficient production of surfactant in the lungs of preterm infants. As a result, researchers have looked into the possibility of surfactant replacement therapy as a means of preventing and treating RDS. We sought to identify the role of surfactant in the prevention and management of RDS, comparing the various types, doses, and mod...

core flooding experiments were conducted with the objective of evaluating near miscible surfactant alternating co2 injection and the effect of surfactant concentrations on gas-oil and water displacements in porous media. the core samples were provided from a low permeability mixed wet oil reservoir at 156 °f and 1900 psia. in addition, very few studies of surfactant adsorption on carbonate mine...

in this research, effect of bicomponent mixed surfactant was studied on drop interface coalescence phenomenon in ambient temperature. first basic chemical system was water and toluene and 0.01 gr of sodium dodecyle sulfate (sds) and the second basic system was water and toluene and 0.01 gr of cethyl trimethy amonium bromide (ctab). various weight fractions of second surfactant including 2-hepta...

the topical delivery of non-steroidal anti-inflammatory drugs (nsaids) such as ibuprofen has been explored as a potential method of avoiding the first pass effects and the gastric irritation, which may occur when used orally. ibuprofen is formulated into many topical preparations to reduce the adverse effects and simultaneously avoid the hepatic first-pass metabolism as well. however, it is dif...

based on the {s+, i-} pathway, the concentration of surfactant and surface charge density of silanolate groups control the phase transition from lamellar, to hexagonal through cubic form. the high surface charge density of silanolate groups was observed for the lamellar phase. with decrease of molar concentration of surfactant on the gel, the yield of reaction decreases and the stability of mes...

Result: Specific IgE antibodies were detected in 29/42 (69%) of all the subjects. The sensitization rate was highest for pollen while results for other allergen groups are as follows: pollen 86/127 (66.9%), animal dander 29/127 (22.8%), HDM 11/127 (8.6%) and moulds 2/127 (1.6%). Among allergenic pollen, mixed grasses were the most common cause of sensitization 14/127 (11.0%). Sensitization rate...
