The chair-side work posture of dental hygienists has long been a concern because of health-related problems potentially caused or exacerbated by poor posture. The purpose of this study was to investigate if using magnification loupes improved dental hygiene students' posture during provision of treatment. The treatment chosen was hand-scaling, and the effect of the timing of introduction of the...

Declaration I declare that the work described in this dissertation is, except where otherwise stated, entirely my own work and has not been submitted as an exercise for a degree at this or any other university.

This study tested whether warnings can result in a better working posture with respect to RSI prevention compared with an educational brochure. By using a warning, the information provision on how to prevent RSI can be shorter and only interrupts with the task at hand for a short time. Five conditions were created to compare the effects on position adjustments of a warning displayed on the comp...

In the crystal structure of the title molecular salt, 3C2H5N4(+)·HPO4(2-)·H2PO4(-)·3H2O, the phosphate-based framework is built upon layers parallel to (010) made up from the H2PO4(-) and HPO4(2-) anions and water mol-ecules, which are inter-connected through O-H⋯O hydrogen bonds. The organic cations are located between the phosphate-water layers and are connected to them via N-H⋯O hydrogen bon...

Purpose: To develop ampicillin trihydrate-loaded chitosan nanoparticles by modified ionic gelation method and evaluate their antimicrobial activity. Methods: Ampicillin trihydrate-loaded chitosan nanoparticles were prepared by ionic gelation method with the aid of sonication. Parameters such as the zeta potential, polydispersity, particle size, entrapment efficiency and in vitro drug release of...

Individuals often receive judgements from others based on their clothing and their posture. While both of these factors have been found to influence judgements of competency independently, their relative importance in impression formation is yet to be investigated. We address this by examining interactive effects of posture and clothing on four competency measures: confidence, professionalism, ...

Phase change materials (PCM) have been widely used in Thermal Energy Storage (TES) Systems. Considering the energy efficiency and use of domestic hot water, melting temperature range phase is considered to be optimal 50–60 °C. The most commonly sodium acetate trihydrate-based material, which has advantages high latent heat low price, but its supercooling, thermal conductivity, separation affect...
