Effect of Physical Education Programme and Game Specific Exercises on Selected Health Related Physical Fitness and Physiological Variables among College Level Volleyball Players

The purpose of the study was to find out the effect of physical education programme and game specific exercises on selected health related physical fitness and physiological variables of men volleyball players. To achieve this purpose of the study sixty men volleyball players were selected studying Bachelor’s degree in the Department of Physical Education, Bharathidasan University, Tiruchirapalli TamiNadu, India at randomly. They were divided into three equal groups of each fifteen players as physical education programme group (Group I), game specific exercises training group (Group II) and act as control group (Group III). Group I and II were underwent their respective training programme for three days per week for six weeks who did not underwent any special training programme a part from their regular physical education curriculum. The following physical and physiological variables such as muscular endurance, flexibility, resting pulse rate and breath holding time were selected as criterion variables. All the subjects of three groups were tested on selected criterion variables at prior to and immediately after the training programme as pre and post test selected. Analysis of covariance (ANCOVA) was used to find out the significant difference if any, among the groups on each selected criterion variables separately. In all the cases, .05 level of confidence was fixed to test the significance, which was considered as an appropriate. There was a significant difference among physical education programme training group, game specific exercises training group and control group on physical and physiological variables among muscular endurance, flexibility, resting pulse rate and breath holding time

Effects of Selected Yogic Practices and Physical Exercises on Selected Motor Ability Components and Physiological Variables for High School Boys

The purpose of the study was to examine the effects of selected yogic practices and physical exercises on selected motor ability components and physiological variables for high school boys. For the study 100 student’s age ranging from 12 to 15 were selected for a 6 weeks yogic practices and physical exercises. The experimental design used for this study was a random group design. The selected subjects were divided into four groups of 25 each, namely Control Group (Group A), Physical Exercise Group (Group B), Yogic Practice Group (Group C) and Physical Exercise and Yogic Practice Group (Group D). The experimental groups (Groups B, C&D) underwent training for a period of six weeks whereas the control group maintained their routine activities and no special training was given. The subjects of the four groups were tested using standardized tests and procedures on selected motor ability components and physiological variables before and after the training period to find out the effects of the training. The data pertaining to selected motor ability components and physiological variables were analyzed by ANCOVA at P<0.05 and it concluded that experimental group showed improvement than control group

The crossfield current-driven ion acoustic instability in a two-ion plasma.

Thesis (M.Sc.)-University of Durban-Westville, 1987.The behaviour of the crossfield current-driven ion acoustic instability in a plasma containing two ion species is theoretically examined. In our model the electrons are assumed to be hot and the ions cold, i.e. Tₑ »Tᵢ (~ 0), where both ion species are given the same temperature. The length and time scales are such that the electrons are magnetized and the ions unmagnetized. The linearised Vlasov equation is used to set up a dispersion relation for electrostatic waves for Maxwellian equilibrium velocity distributions of the electrons and ions. For the ion acoustic wave, a study is made of the dependence of the critical electron drift velocity (Vͨₒ) required to excite an instability on several parameters. The parameters include light ion fraction, heavy to light ion mass ratio, magnetic field strength and the propagation angle. In general the maximum value of Vͨₒ is found to be smaller than that for an unmagnetized plasma. Approximate analytic solutions of the dispersion relation are used to make comparisons with solutions from the full dispersion relation. The effect of drifts due to inhomogeneities in external magnetic field, perpendicular electron temperature and electron density on the growth rate of the ion acoustic instability are investigated in the ion rest frame. Finally, in a reference frame in which the electrons are stationary, both ion species are given external drifts. The effects of the ion drift velocities (both equal and unequal), electron to ion temperature ratio, light ion fraction, and heavy to light ion mass ratio on the growth rate of the ion acoustic instability are then studied

Do Web 2.0 social media impact transnational social advocacy? : a study of South African civil society and Greenpeace.

Ph.D. University of KwaZulu-Natal, Durban 2012.This study focuses on how civil society organisations deploy Web 2.0 technologies for transnational social advocacy, the context of this technology use, and the effect of this adoption in achieving organisational goals. It analyses the effectiveness of these technologies in an attempt to understand the strategic intent in deploying these social media services. The reciprocal impact of this technology adoption on civil society organisations’ roles, structure, and orientation was also investigated. The technologies targeted for study are those commonly described as Web 2.0 social media including social networking sites, blogs, podcasts and wikis amongst others. While the literature points to many studies relating to the use of the Internet for advocacy it also suggests that emerging technologies have not been studied in any detail. In particular there are no recent studies that investigate Web 2.0 technologies. These studies have the potential to provide new perspectives to current theoretical frameworks. This study is designed as part case study and part exploratory. The research adopts an interdisciplinary approach using both qualitative and quantitative methods. A survey of South African civil society organisations painted a picture of the extent of adoption of Web 2.0 social services across South African civil society, and detailed the reasons, and the benefits - both perceived and actual - of such adoption. The global environmental justice organisation, Greenpeace is used as a case study. The organisation’s major goal is to advocate for changes in environmental policy and behaviour, has been at the forefront of environmental issues since its inception, and has used the mass media as an effective campaigning tool. The key findings that emerged in the South African context was that of a sector that has a low-level of knowledge of social media services and an accompanying low level of adoption. This is partly explained by factors at a national level including macro-economic policies, and a low level of Internet penetration and ICT readiness. Using Greenpeace as a case study revealed that while social media-led activism is increasingly being seen as strategic, there is a level of organisational introspection that is required to precisely determine how traditional CSOs can exploit social media while maintaining their core values and traditions. Social media is not a panacea for the issues confronting activism in an increasingly connected world, but rather is seen as complementing traditional advocacy with its ability to coordinate, synchronise and document campaigns

Spherically symmetric cosmological solutions.

Thesis (Ph.D.)-University of Natal, Durban, 1996.This thesis examines the role of shear in inhomogeneous spherically symmetric spacetimes in the field of general relativity. The Einstein field equations are derived for a perfect fluid source in comoving coordinates. By assuming a barotropic equation of state, two classes of nonaccelerating solutions are obtained for the Einstein field equations. The first class has equation of state p = ⅓µ and the second class, with equation of state p = µ, generalises the models of Van den Bergh and Wils (1985). For a particular choice of a metric potential a new class of solutions is found which is expressible in terms of elliptic functions of the first and third kind in general. A class of nonexpanding cosmological models is briefly studied. The method of Lie symmetries of differential equations generates a self-similar variable which reduces the field and conservation equations to a system of ordinary differential equations. The behaviour of the gravitational field in this case is governed by a Riccati equation which is solved in general. Another class of solutions is obtained by making an ad hoc choice for one of the gravitational potentials. It is demonstrated that for a stiff fluid a particular case of the generalised Emden-Fowler equation arises

Coronary artery height differences and their effect on fractional flow reserve

Background: Fractional flow reserve (FFR) uses pressure-based measurements to assess the severityof a coronary stenosis. Distal pressure (Pd) is often at a different vertical height to that of the proximalaortic pressure (Pa). The difference in pressure between Pd and Pa due to hydrostatic pressure, mayimpact FFR calculation.Methods: One hundred computed tomography coronary angiographies were used to measure heightdifferences between the coronary ostia and points in the coronary tree. Mean heights were used to calculate the hydrostatic pressure effect in each artery, using a correction factor of 0.8 mmHg/cm. Thiswas tested in a simulation of intermediate coronary stenosis to give the “corrected FFR” (cFFR) andpercentage of values, which crossed a threshold of 0.8.Results: The mean height from coronary ostium to distal left anterior descending (LAD) was +5.26 cm,distal circumflex (Cx) –3.35 cm, distal right coronary artery-posterior left ventricular artery (RCA-PLV)–5.74 cm and distal RCA-posterior descending artery (PDA) +1.83 cm. For LAD, correction resulted in a mean change in FFR of +0.042, –0.027 in the Cx, –0.046 in the PLV and +0.015 in the PDA. Using 200 random FFR values between 0.75 and 0.85, the resulting cFFR crossed the clinical treatmentthreshold of 0.8 in 43% of LAD, 27% of Cx, 47% of PLV and 15% of PDA cases.Conclusions: There are significant vertical height differences between the distal artery (Pd) and its point of normalization (Pa). This is likely to have a modest effect on FFR, and correcting for this results in a proportion of values crossing treatment thresholds. Operators should be mindful of this phenomenon when interpreting FFR values

Impact of point-of-care pre-procedure creatinine and eGFR testing in patients with ST segment elevation myocardial infarction undergoing primary PCI: The pilot STATCREAT study

Background: Contrast-induced acute kidney injury (CI-AKI) is a recognised complication during primary PCI that affects short and long term prognosis. The aim of this study was to assess the impact of point-of-care (POC) pre-PPCI creatinine and eGFR testing in STEMI patients. Methods 160 STEMI patients (STATCREAT group) with pre-procedure POC testing of Cr and eGFR were compared with 294 consecutive retrospective STEMI patients (control group). Patients were further divided into subjects with or without pre-existing CKD. Results: The incidence of CI-AKI in the whole population was 14.5% and not different between the two overall groups. For patients with pre-procedure CKD, contrast dose was significantly reduced in the STATCREAT group (124.6 ml vs. 152.3 ml, p = 0.015). The incidence of CI-AKI was 5.9% (n = 2) in the STATCREAT group compared with 17.9% (n = 10) in the control group (p = 0.12). There was no difference in the number of lesions treated (1.118 vs. 1.196, p = 0.643) or stents used (1.176 vs. 1.250, p = 0.78). For non-CKD patients, there was no significant difference in contrast dose (172.4 ml vs. 158.4 ml, p = 0.067), CI-AKI incidence (16.7% vs. 13.4%, p = 0.4), treated lesions (1.167 vs. 1.164, p = 1.0) or stents used (1.214 vs. 1.168, p = 0.611) between the two groups. Conclusions: Pre-PPCI point-of-care renal function testing did not reduce the incidence of CI-AKI in the overall group of STEMI patients. In patients with CKD, contrast dose was significantly reduced, but a numerical reduction in CI-AKI was not found to be statistically significant. No significant differences were found in the non-CKD group
