Abstract This study aims to determine the effect of activator-binder ratio on water absorption ambient-cured geopolymer concrete. Class F fly ash from Mpanau power plant was used as precursor. raw material activated by a mixture sodium silicate and hydroxide solution, with an 0,45; 0,50; 0,55; 0,60. Five percent replacement slaked lime added achieve ambient curing. The test specimen for is made...

1. Strontium absorption was studied in vivo with loops of ileum in rachitic chicks and found to be increased by vitamin D(3), bile salts and sodium lauryl sulphate. 2. Bile salts and sodium lauryl sulphate rendered strontium soluble in butanol-benzene (1:1, v/v). 3. Bile was not concerned in the absorption of iron in rats from its water-soluble form, ferrous sulphate. 4. Ligation of the bile du...

Salt-sensitive hypertension is common in people of African origin, and may be caused by increased transepithelial sodium absorption. The pH of nasal secretions is negatively correlated with the difference in Na(+) concentration between nasal secretions and plasma, and may be a marker of transepithelial sodium absorption. Nasal pH was measured using a probe sited under the inferior turbinate. Me...

The utilization of used polystyrene as adhesive material for emulsion polymer asphalt has been carried out. Polystyrene foam was dissolved in toluene at the ratio 30:70 mL, then solution mixed with aquadest ratios 90: 10 70: 30 50: 50 and 10: 90 mL. Then added mL Sodium Dodecyl Sulfate concentrations 10%, 20%, 30%. most stable latex 200 g sand aggregate volume 20 40 mixture pressed into a hotpr...

High intestinal sodium absorption is one mechanism of hypertension and constipation. The sodium-proton-exchanger subtype 3 (NHE3) is an important mediator of sodium absorption in the gut. SAR218034 (SAR) is an orally nonabsorbable specific NHE3 inhibitor. The effect of SAR (1 mg/kg per day in chow) on feces sodium excretion, systolic blood pressure via tail cuff, and gene expression of NHE3 in ...

The normal gut is adapted to intermittent feeding with complex macromolecular substrates of low sodium content. The high permeability of the upper small intestine to sodium, together with sodium rich saliva and pancreaticobiliary secretions results in large sodium fluxes into the lumen. These substantial sodium influxes are matched by equally large effluxes from the ileum and proximal colon, wh...

There is compelling evidence that the presence of actively transported sugars or amino acids in the mucosal solution increases sodium absorption and the transmural electrical potential difference across a variety of in vitro and in vivo preparations of small intestine. The mechanism(s) underlying these effects is, however, unsettled. One possibility invokes a direct interaction between sodium a...

the types of scion-rootstock compound and level of salinity affect on growth characteristics and concentration of nutrition elements of almond leaves and roots. in order to evaluate the effect of salinity stress on vegetative traits and concentration of nutrition elements of leaves and roots almond genotypes, a experiment was carried out with two factors; cultivar in four levels including ‘shah...
