Al2O3-SiO2 diphasic gel was synthesized by sol gel route from aluminium nitrate and silicic acid following aqueous phase colloidal interaction. The precursor gel powder was thoroughly characterized by chemical analysis, measurement of surface area and bulk density measurement. The gel powder was further characterized by thermogravimetry, XRD diffraction stud...

An X-ray diffraction line will broaden considerably when steels change into martensitic structure on quenching. The results presented in this paper show that X-ray diffraction technique can be employed for a rapid and nondestructive measurement of hardness of hardened steel. Measurement on various quenched and tempered steels showed that the breadth of its diffraction peak increased with increa...

background & aim: although cold and heat have been recommended for labor pain relief, comparison of them and intermittent change in cold and heat therapy has been less considered. this study compared the effects of separate and intermittent heat and cold on labor pain relief and some birth outcomes . methods & materials : this was a randomized clinical trial. ninety-six parturient women were ra...

In this paper, the innovative intelligent fuzzy weighted input estimation method (FWIEM) can be applied to the inverse heat transfer conduction problem (IHCP) to estimate the unknown time-varying heat flux efficiently as presented. The feasibility of this method can be verified by adopting the temperature measurement experiment. We would like to focus attention on the heat flux estimation to th...

Metallized plastic sheeting (m.p.s.) was used in 14 neurosurgical patients and changes in body heat content during surgery compared with those of 14 control patients. All patients, except three in the study group and one in the control group, lost heat by the end of the operation. There was, however, a statistically significant reduction in heat loss in the patients wrapped in m.p.s. Measuremen...

conclusions the results suggest that the msfc could be used as a simple tool to detect the negative effects of heat in patients with ms. results in the ms group the average msfc scores were -0.48 (sd 0.79) at baseline, -0.99 (sd 1.97) during heat exposure and -0.68 (sd 1.58) after a one-hour delay. the average msfc scores of the hc group were 0.58 (sd 0.42) at baseline, 0.66 (sd 0.43) during he...

This study investigates the capacity of granular activated carbon (GAC) for the storage of methane through the equilibrium adsorption. An experimental apparatus consist of a dual adsorption vessel was set up for the measurement of equilibrium adsorption of methane on GAC using volumetric technique (pressure decay). Experimental isotherms of methane adsorption were determined by the measurement ...
