Prediction of Upper Body Strength By Using Grip Strength Test in Division II American College Football Players’ Grip Strength

The purpose of this study was to investigate if the grip strength could be used to predict upper body strength of college football players through comparing dominant grip strength and upper body strength of col­lege football players. Forty-one Division II National Col­legiate Athletic Association football players (24 defen­sive players and 17 offensive players) participated in the present study. A grip strength dynamometer was used to measure grip strength of football players and the one-repetition maximum (1RM) bench press was used to measure participants’ upper body strength. Each play­er had undergone a minimum of eight weeks of heavy resistance training during the winter off-season con­ditioning program prior to measurement. None of the participants had a serious pre-existing injury that could hinder their performance throughout the study, and participants in the study had the ability to understand and perform bench press and grip strength tests. The Pearson product-moment coefficients of correlation and a simple regression were computed to determine relationship between 1RM bench press and grip strength. One-way analyses of variance (ANOVA) were conducted to test the differences in upper body and grip strength among offensive and defensive college football players and their player positions by using their relative strength. Notably, strength scores were divided by body weights to express bench press and grip strength relative to weight. The results of this study showed that grip strength test did not predict the upper body strength of college foot­ball players when we used the 1RM bench press strength test as a standard test to measure upper body strength of players (β = .248, p = .118)

The Performance of the Higher-Order Radiation Condition Method for the Penetrable Cylinder

We have considered the scattering of a plane wave by a penetrable acoustic circular cylinder. The boundary conditions are continuity of the total pressure and the total velocity. The wave speed and density of the target are different from that of the surrounding medium. We investigated the performance of higher-order SRCs up to L4 operator in two dimensions. We assume that in the rectangular Cartesian system of axes, (x,y,z), the z axis coincides with the axis of the cylinder and an incident wave propagates in a direction perpendicular to the z axis. All the field quantities are then independent of z. Numerical results are added to present the change of the module of the total field and the magnitude of the far field with respect to θ

Beyond mean-field approach to heavy-ion reactions around the Coulomb barrier

Dissipation and fluctuations of one-body observables in heavy-ion reactions around the Coulomb barrier are investigated with a microscopic stochastic mean-field approach. By projecting the stochastic mean-field dynamics on a suitable collective path, transport coefficients associated with the relative distance between colliding nuclei and a fragment mass are extracted. Although microscopic mean-field approach is know to underestimate the variance of fragment mass distribution, the description of the variance is much improved by the stochastic mean-field method. While fluctuations are consistent with the empirical (semiclassical) analysis of the experimental data, concerning mean values of macroscopic variables the semiclassical description breaks down below the Coulomb barrier.Comment: 6 pages, 6 figures.

Open Access to Digitized Cultural Heritage: A Model Proposal for Turkey

Cultural values, which are homogenized by the effect of globalization, have endangered nations with the risk of losing their local cultures. Sensibility of conservation and acknowledging cultural properties with the society they belonged to, has increased the efforts to protect cultural heritage products with a sustainable understanding and make them massively accessible. Unhindered access to cultural heritage products can be provided by cultural memory institutions, such as libraries, archives and museums, which open up their digital doors and increase their visibility on the web. The aim of this study is to propose a model that will lead to open access to digitized cultural heritage - in the case of Turkey. The model, which is expected to guide the legal, technical, administrative and financial processes of open access to cultural heritage, is thought to contribute to the discovery of cultural heritage products at universal level, the development of creativity in the individual and social context and the adoption of standard approaches in cultural heritage management

Use of caffeic acid phenethyl ester and cortisone may prevent proliferative vitreoretinopathy.

PURPOSE: To investigate whether caffeic acid phenethyl ester (CAPE) and cortisone prevent proliferative vitreoretinopathy (PVR). METHODS: Twenty pigmented rabbits were used in this study. All rabbits except controls received an intravitreal injection of 0.15 ml (75,000 U) of platelet-rich plasma into their left eye. The animals were divided into four groups: group I was treated with intraperitoneal injection of 0.5 ml (15 micromol/kg) of CAPE for 3 days, group II received 0.15 ml (4 mg/kg) of intravitreal cortisone, group III received nothing (blank group), and group IV (control group) received only 1 ml of 1% ethanol intraperitoneally daily for 3 days. Proliferative changes were graded in a masked fashion by indirect ophthalmoscopy for a 15-day follow-up period. The malondialdehyde (MDA), reduced glutathione (GSH) and total nitrite (NO) levels were measured in the vitreous humor. RESULTS: The grades of PVR were B-C in group I, and C-D in group II. The PVR grade in the control group was C-D. The mean MDA level in group I (4.0+/-0.8 micromol/l) was significantly lower than in the blank group (6.0 micromol/l) (p < 0.05). The mean GSH level in group I (71.0+/-11.2 micromol/l) was significantly different than in the blank group (p < 0.05). The MDA and GSH levels in group II were 4.7+/-0.6 micromol/l and 53.8+/-7.8 micromol/l, respectively. Both these levels were not significantly different from the blank group (p > 0.05). The NO levels in both treatment groups were significantly lower than in the blank group (p < 0.001). CONCLUSION: These findings suggest an inhibitory effect of CAPE on PVR. The inhibitory effect was supported by lower MDA and NO with higher GSH levels in treatment groups than in the blank group. There was no detected significant effect of cortisone for preventing PVR experimentally
