BACKGROUND Physical activity is essential for optimal physical and psychological health but substantial declines in children's activity levels have occurred in New Zealand and internationally. Children's independent mobility (i.e., outdoor play and traveling to destinations unsupervised), an integral component of physical activity in childhood, has also declined radically in recent decades. Saf...

With the increasing storage capacity of computers, it became evident that the use of a hierarchical le system no longer ts the interests of the user, i.e., with this kind of le system the user cannot nd a le in an easy, quick and intuitive way. For this reason, the concept of Semantic File System became quite popular. This is a system for storing and organizing information, that allows associat...

Team handball is an Olympic sport played professionally in many European countries. Nevertheless, a scientific knowledge regarding women's elite team handball demands is limited. Thus, the purpose of this article was to review a series of studies (n = 33) on physical characteristics, physiological attributes, physical attributes, throwing velocity, and on-court performances of women's team hand...

Physics-Based Simulations for Fluid Mixtures Dongwoon Lee Doctor of Philosophy Graduate Department of Computer Science University of Toronto 2007 We develop a physics-based particle method to simulate various fluid mixture effects. A particle method is chosen over a grid-based method because we believe a particle method is more intuitive and better suited for handling physical and chemical inte...

When quantum mechanics was being established in the mid 1920’s, Paul A. M Dirac did not seek a visualizable model of the electron or other quantum mechanical objects. But a number of the quantitative physical properties of the electron described by the Dirac equation are of a spatial or temporal nature that can lend themselves to visualizable physical modeling. A recently proposed superluminal ...

Textbooks play a crucial role in English language teaching and learning. One of the methods for selecting the most appropriate textbook for a particular educational purpose is comparing two or several similar textbooks with each other. Textbook evaluation can provide useful information about the strengths and weaknesses of textbooks and can lead to the selection of the most suitable materials f...

The aim of this study was to identify the tactile dimensions in the discrimination of light-weight wool fabrics. The participants judged the overall similarity between 21 light-weight wool fabrics using free sorting tasks. The fabrics were evaluated using active touch with limited exploratory procedure. Multidimensional scaling (MDS) was used to generate the perceptual space, revealing one dime...
