The electrical conductivity and density of the low-melting CaCl2-NaCl-Al2O3 systems at 550°C~800°C ranges were respectively measured by the Continuously Varying Cell Constant Technique, ac-techniques and Archimedes method. The materials were applied as the electrolyte for the direct electrochemical reduction solid Al2O3 at 550°C ~800°C. The materials were composed of 71wt.%~87wt.%CaCl2 (corresp...

Four novel anion-nonionic surfactants were synthesized using cashew phenol as raw material. The four structures were characterized by IR and elemental analysis. Their surface activities were investigated. Their critical micelle concentrations (CMC) are 9.30 × 10 mol/L, 8.50 × 10 mol/L, 8.10 × 10 mol/L and 7.71 × 10 mol/L respectively, and the corresponding surface tensions at CMC are 28.38 mN/m...

PURPOSE The primary purpose of this study is to propose a method for the simultaneous quantitative three-dimensional (3D) mapping of conductivity and susceptibility using double-echo ultrashort echo time (UTE) imaging. The secondary purpose is to investigate the changes of these properties over time during in vitro hematoma evolution in blood samples. METHODS The first and second set of echo ...

Sodium measurement during hemodialysis treatment is important to preserve the patient from clinical events related to hypo- or hyper-natremia Usually, sodium measurement is performed through laboratory equipment which is typically expensive, and requires manual intervention. We propose a new method, based on conductivity measurement after treatment of dialysate solution through ion-exchange res...

The conductivity of human erythrocyte cells dispersed in various uni-univalent electrolyte solutions (NaCl, KCl, LiCl, CsCl; 0.15 M) have been measured in the frequency range from 10 KHz to 100 MHz at five temperatures between 5 and 45 degrees C. The results were analyzed in the light of the theory of conductivity polarization of a suspension of ellipsoidal particles-covered with two confocal s...

objective: studies have demonstrates that physical properties of denture base affect patient satisfaction and acceptance. thermal conductivity is among the most important properties of denture base influencing the sense of taste and gingival health. the conventionally used acrylic resin has a low coefficient of thermal conductivity. this study aimed to improve the thermal conductivity of acryli...

In a two-bottle test, Sprague-Dawley rats preferentially consume a greater amount of hypotonic and isotonic NaCl solutions relative to water, whereas inbred Fischer 344 (F344) rats fail to prefer NaCl solutions at any concentration relative to water. To determine whether taste contributes to this strain difference, we measured the integrated neural responses of the chorda tympani nerve to a con...
