Experts agree that computers and computing play an important role in education. Since the 1980s there has been a debate about gender as it relates to computers and education. However, results regarding gender differences concerning computer use in education are not consistent. In particular there is little work done in China on this issue. Therefore, the overall goal of this paper is to demonst...

This paper describes the process of the formative evaluation of an acoustics computer-aided learning (CAL) package. The CAL package, entitled “Waves: Analysis and Synthesis”, is a multimedia-rich learning support package for students on sound-related undergraduate courses. The evaluation took place over a two-month period in the School of Acoustics and Electronic Engineering at the University o...

A Compact Aerosol Lidar (CAL) was built in the Science Directorate at NASA Langley for the purposes of aerosol and cloud profiling. The aircraft lidar system uses a Nd:YAG pulsed laser operating at 1064-nm and 532-nm wavelengths, with an additional photon counting channel at 532-nm. Measurements made in the Norfolk-Virginia Beach region showed complex regional aerosol distributions. Comparisons...

BACKGROUND An aerosol foam formulation of fixed combination calcipotriene 0.005% (as hydrate; Cal) plus betamethasone dipropionate 0.064% (BD) was developed to improve psoriasis treatment. OBJECTIVES To compare the efficacy and safety of Cal/BD aerosol foam with Cal/BD ointment after 4 weeks. METHODS In this Phase II, multicenter, investigator-blind, 4-week trial, adult patients with psoria...

In assessing the nutritional status of populations, it is becoming increasingly common to measure not only the total food intake but also the energy expenditure of groups of individuals. I t is often difficult to compare the results obtained by different authors in such studies of energy expenditure because of the diverse ways in which these results may be expressed. The metabolic cost of a per...

Complete dentures rest on basal seat area which is primarily oral mucosa and residual alveolar ridge .The oral mucosa on which complete dentures are fabricated is displacable and compressible. This factor was described by Hanau as ‘resiliency and like effect’, Realeff Effect. Realeff plays an important role In all the steps of compete denture fabrication as in primary impression , border mouldi...

BACKGROUND The biocompatibility of two forms of calcined mesoporous silica particles, labeled as MCM41-cal and SBA15-cal, with fetal blood mononuclear cells was assessed in vitro. METHODS AND RESULTS Fetal mononuclear cells were isolated from umbilical cord blood and exposed to 0.5 mg/mL of MCM41-cal or SBA15-cal for several hours. Transmission electron micrographs confirmed the presence of p...

The contribution of heat shock protein 72 (HSP72) to the protection of cardiac function was examined in rats with chronic heat failure (CHF) following coronary artery ligation (CAL). The CAL animals revealed functional deterioration without low cardiac output 2 wk after CAL and with low cardiac output 8 wk after CAL, suggesting that CHF had developed by 8 wk after CAL. The hearts isolated from ...
