This study deals with the development and assessment of rubberised one-part alkali-activated concrete. An experimental programme, focusing on optimising material proportions for high flowability compressive strength, is firstly described. includes varying aluminosilicate precursors, binder-to-aggregate ratio, activator dosage, admixture quantity to find an optimum mix design stable strength up ...

Introducing an interaction parameter γ, we implement modifier interaction and the mixed-alkali effect into bond constraint theory and apply this extension for simplistic property prediction on ternary phosphate glasses. The severity of the mixed-alkali effect results from the interplay of two simultaneous contributions: bond constraints on the modifier species soften and stiffen with decreasing...

the measurement of anti-streptokinase antibodies can distinguish the patients who may benefit from streptokinase and those who should be treated with some other thrombolytic regimen. neutralising titration test is a commonly used classical assay for measuring anti-streptokinase antibodies and in this assay the ability of anti-streptokinase antibodies in patients' sera in preventing the lytic ef...

Purpose To investigate the effect of naringenin eye drops in corneal neovascularization induced by alkali (1 N NaOH) burn in mice. Methods Corneal neovascularization in the right eye of male Swiss mice was induced by alkali. Treatment with naringenin eye drops (0.08-80 μg; 8 μL of 0.01-10 g/L solution) or vehicle (saline) started 2 days before corneal neovascularization was induced and was pe...

PURPOSE To investigate the effect of netrin-1 on alkali burn-induced corneal inflammation and neovascularization. METHODS The expression of netrin-1 and its receptors UNC5A, UNC5B, UNC5C, UNC5D, adenosine 2b receptor (A2BAR), deleted in colorectal cancer (DCC), and neogenin in normal and alkali-burned rat cornea were determined by RT-PCR and/or Western blot analysis, or immunostaining. Topica...

Addition of Li, Na, K and Cs to a 1.5 wt% Rh/Al,O, catalyst resulted in a decrease of the hydrocarbon formation rate, while the methanol formation rate was almost unaffected. The overall result is an increased oxygenate selectivity at a decreased total activity. The oxo-selectivity increased in the order unpromoted < Li < Na< K < Cs. The results suggest that the main role of the alkali promoter...

The effects of non-steroidal anti-inflammatory drugs and prostaglandins E(2) and F(2alpha) on the secretory and electrical activity of isolated rabbit fundic mucosa have been studied. Spontaneous acid secretion was inhibited by serosal side application of sodium thiocyanate (6x10(-2)M) and the resulting alkali secretion measured by pH stat tiration. Serosal side application of indomethacin (10(...

Previous work reported from JPL has included characterization of eleetrode kinetics and alkali atom transport from electrodes including MO) W, WRhX, WPtX(Mn), in sodium AMTEC cells and vapor exposure cells; and Mo in potassium vapor exposure cells. [Williams, cl al., 1990a, 1991, 1992] These studies were generally performed in cells with small area electrodes (about 1 to 5 cm2), and device geom...
