The effect of high methoxy apple pectin, a carbohydrate gelling agent, on the intestinal absorption of glucose, water, and sodium was studied in man. The effect of intraluminal fibre was evaluated in 22 healthy volunteers by the intestinal perfusion technique under an occlusive balloon. The test solutions (NaCl 130 mM, KCl 5 mM, glucose or mannitol 30 mM, PEG 4000 5 g/l) were perfused just beyo...

Clean drinking water for the municipality of “Rey” with population of over one million remains a critical and serious problem. In particular, Rey’s continued water demands has caused a substantially high drop in its local groundwater level. With running this study, we can appropriately predict the quality of groundwater in Rey. In this study, we have considered presence of nit...

Using a constant perfusion technique, sodium and bicarbonate absorption was studied in human subjects. The following observations were made on sodium absorption from saline solution: (a) the rate of sodium absorption is markedly influenced by bulk water flow, (b) when net water flow is zero, sodium absorption is zero if there are no concentration gradients between plasma and lumen that favor ne...

Separation of low boiling gas mixtures is widely concerned in process industries. Now their separations heavily rely upon energy-intensive cryogenic processes. Here, we report a pseudo-absorption process for separating low boiling gas mixtures near normal temperature. In this process, absorption-membrane-adsorption is integrated by suspending suitable porous ZIF material in suitable solvent and...

TO THE EDITOR: All published comparisons of local sweat sampling techniques (e.g., filter paper, gauze, skin scraping, pipette, rubber glove, or arm bag collections) versus the whole body wash down method have reported that local samples contained higher electrolyte concentrations (4). The present paper by Weschler (5) provides a hypothetical mechanism for these findings [i.e., sweat leaches el...

throughout the present research, squash (cucurbita pepo) slices (0.4 cm thickness and 4 cm diameter) were blanched in a steam chamber for 4 min. following cooling to room temperature, the squash slices were dehydrated by use of a hotair dryer, under air temperature of 60°c up to moisture content of 0.1065 kg h2o per kg d.m. squash slices of specified weights were rehydrated by immersion in dist...

PURPOSE The aim of this study was to compare the bonding strength, flexural strength, elastic modulus, water absorption and the expansion after water storage of new self-adhesive resin cements to commercially available dental cements. METHODS Two types (hand-mix and auto-mix) of new self-adhesive resin cements (SAC-H and SAC-A, Kuraray Medical), one conventional resin cement (Panavia F2.0), t...

groundwater quality in nour coastal plain in mazandaran province of iran is assessed by measuring physicochemical parameters including total dissolved solid, electrical conductivity, ph, total hardness, major cation and anion compositions and nitrate pollution. for this purpose, fifty groundwater samples were collected in july 2012. the hydrochemical types, ca–hco3 and mg–hco3 dominate in all s...

the influence of flour content and immersion time in water on the creep behavior of composites made from high density polyethylene (hdpe) waste and mdf (medium density fiberboard) flour was investigated. mixing was carried out by a twin screw extruder and the sample was manufactured by flat hot press. firstly, the modulus of elasticity and bending strength of various mdf flour-polyethylene comp...

A model for exchange of water from the atmosphere to condensing CO2 caps is developed. The rate of water condensation in the caps is assumed to be proportional to the meridional heat flux. It follows that the amount of water condensed in the caps varies inversely with the amount of CO2 condensed. The seasonal phase of the release of water from the caps is not consistent with observed variations...
