The densities of aqueous solutions of d -glucose were measured at temperatures from (293.15 to 433.15) K and pressures from (0.10 to 50.00) MPa using a vibrating-tube densimeter. Apparent molar volumes Vφ,m and partial molar volumes at infinite dilu

The potential benefits of teacher leadership are widely acknowledged; however, the conceptualization of this construct is in need of theoretical development and analytic clarification. The purpose of this mixed methodology study was to operationalize

Although lesson study is increasingly adopted in the United States (U.S.), the impact of lesson study on teacher learning is uncertain. This study presents a theoretically grounded set of codes to systematically document the various aspects of teache

Ambitious efforts are taking place to implement a new vision for science education in the United States, in both Next Generation Science Standards (NGSS)-adopted states and those states creating their own, often related, standards. In-service and pre

Middle school has been documented as the period in which a drop in students’ science interest and achievement occurs. This trend indicates a lack of motivation for learning science; however, little is known about how different aspects of motivation

This study investigates a watershed influenced by acid mine drainage emanating from the former Leona Heights Sulfur Mine, located in Oakland, California. The primary factors that temporally controlled the magnitude of iron photoreduction included ini

An excess molar volume (Vex)-explicit virial equation, and two empirical Vex expressions developed from experimentally determined densities, were used to calculate excess Gibbs free energies (Gex) and activity-composition (a-X) relations for CO2-H2O

Densities of pure CO2 and CO2-H2O mixtures were experimentally determined at 400°C, 10–100 MPa. The data were obtained with a custom-designed high-pressure, high-temperature vibrating-tube densimeter. Conservative estimates of accuracy are P, ± 0

Densities ρ of pure CO2, CH4, and {(1 −x)CO2+xCH4}, {(1 −x)CO2+xN2} and {(1 −x)CH4+xN2} were measured at the pressures (19.94, 29.94, 39.94, 59.93, 79.93, and 99.93) MPa andT= 673.15 K. The measurements were made with a custom-designed, high-p
