AN INVESTIGATION OF THE EFFECT OF COORDINATIVE ABILITY TRAINING PROGRAM ON ATTENTION, VERTICAL JUMP, AGILITY AND REACTION TIME PERFORMANCE OF U-12 TENNIS PLAYERS

The aim of this study was to investigate the effects of coordinative ability training combined with basic tennis training on attention, vertical jump, agility and reaction time of tennis players. A total of 24 tennis players (10 girls-14 boys) voluntarily participated in the study. The experimental group participated in coordinative ability training with basic tennis training for 12 weeks, while the control group only participated in basic tennis training. As a result, a statistically significant difference was found in the vertical jump, agility and attention values of the experimental group, while no significant difference was found in reaction time (p>0.05). As a result, it can be said that coordinative ability training has an effect on jumping, agility and attention

What are the determinants of economic growth in Muslim countries?

Muslim countries are generally considered economically behind the non-Muslim countries, culturally conservative, authoritarian, and misogynistic. Although the Muslim population, as a whole, comprises an enormous economic potential, many Muslims in the world contend with poverty and illiteracy. Furthermore, economic disparity among Muslim nations is widening. This article examines the reasons behind economic inequalities among Muslim countries and explores whether Islam hinders economic growth or not. On the contrary to general belief that Islam hinders economic growth, this study showed that Islam by itself has no effect on economic prosperity in Muslim Countries. Using cross-country regression, this empirical research displayed that the adaptation of technology and scientific innovations, investment to human capital, human development, and economic freedom are significant and necessary for economic growth in Islamic countries

Influences of oak utilization on the medium density fiberboard properties

Softwoods are the basic and traditional raw materials for medium-density fiberboard production. However, sustainable consumption of wood material in the production of wood-based products requires material variety. Therefore, the usability of hardwood species in the production and its effects on the board properties should be of interest. Considering this, the influence of oak utilization percentages (30 %, 50 %, 70 %, and 100 %) on the physical (density, thickness swelling-TS 2 and 24 h) and mechanical (modulus of rupture, modulus of elasticity, internal bonding, screw holding resistance, and Janka hardness) properties of medium density fiberboard was evaluated in this study. Boards were factory-made instead of laboratory-made using Quercus petraea (oak), Fagus orientalis (beech), and Pinus sylvester (Scots pine) fibers. According to the results, the modulus of rupture, modulus of elasticity, and Janka hardness values were increased when medium-density fiberboard was produced using only oak fiber. On the contrary, thickness swelling, screw-holding resistance, and internal bonding properties were decreased

On well-posedness of piecewise affine bimodal dynamical systems

Çamlıbel, Mehmet Kanat (Dogus Author) -- Conference full title: 19th International Symposium on Mathematical Theory of Networks and Systems – MTNS 2010, 5–9 July, 2010, Budapest, Hungary.The theory of differential inclusions provides certain sufficient conditons for the uniqueness of Filippov solutions such as one-sided Lipschitzian property or maximal monotone condition. When applied to piecewise affine dynamical systems, these conditions impose rather strong conditions. In this paper, we provide less restrictive conditions for uniqueness of Filippov solutions for the bimodal piecewise affine systems
