Effects of Combined Physiotherapy Hold Relax and Glucosamine to the Decrease of COMP through Pain reduction, Increase Muscle Strength and addition of Osteoarthritis of the Knee Joint ROM

The purpose of this study was to determine the effect of a combination of administration Hold Relax (HR) and glucosamine in reducing the levels of COMP through decreased pain, increased muscle strength, and the addition of Osteoarthritis (OA) of the knee joint ROM. This study is a quasi-experimental design with two groups of pre and posttest controlled group design, in which subjects were divided into two groups: Group 1 was given 3 times the treatment of HR within a day and glucosamine one capsule per day for 1 week and Group 2 was given 6 HR treatment time within a day and glucosamine once daily for 2 weeks. Measurements were performed before and after treatment for the time specified by the respective groups to determine the value of the Range of Motion (ROM), VAS, MMT and COMP levels (serum).These results indicate that there is a significant difference in pain reduction (95% confidence level) between the two groups in which the average reduction in pain was higher than Group 2 Group 1. Likewise with measurements of muscle strength showed that there were significant differences (level 95%) between the two groups in which the average increase in muscle strength higher than Group 2 Group 1. In the measurement result ROM, there is a significant (95% confidence level) between the two groups in which the average addition of ROM in Group 2 higher than group 1. Based on the value of COMP, there is a significant difference (95% confidence level) between the two groups in which the average reduction in the levels of COMP in Group 2 was higher than group 1. The result of Pearson correlation test showed that there is a significant correlation between the increase in ROM with a decrease in pain (r = 0.636 or 63.6%). There is also a significant correlation between increased ROM with decreased levels of COMP (r = 0573 or 57.3%). Likewise, there is a significant correlation between reduced levels of COMP with a decrease in pain (r = 0402 or 40.2%). From these results it can be concluded that the combination of physiotherapy HR and glucosamine is effective in towards decreased levels of COMP through decreased pain, increased muscle strength, increase ROM at osteoarthritis knee joint, where the provision of physiotherapy HR 6 times within a day and glucosamine once per day in two weeks more effective than the combination of HR administration physiotherapy 3 times within a day and glucosamine once per day in one week

The incorporation of fixed cost and multilevel capacities into the discrete and continuous single source capacitated facility location problem

In this study we investigate the single source location problem with the presence of several possible capacities and the opening (fixed) cost of a facility that is depended on the capacity used and the area where the facility is located. Mathematical models of the problem for both the discrete and the continuous cases using the Rectilinear and Euclidean distances are produced. Our aim is to find the optimal number of open facilities, their corresponding locations, and their respective capacities alongside the assignment of the customers to the open facilities in order to minimise the total fixed and transportation costs. For relatively large problems, two solution methods are proposed namely an iterative matheuristic approach and VNS-based matheuristic technique. Dataset from the literature is adapted to assess our proposed methods. To assess the performance of the proposed solution methods, the exact method is first applied to small size instances where optimal solutions can be identified or lower and upper bounds can be recorded. Results obtained by the proposed solution methods are also reported for the larger instances

Exergetic and exergoeconomic analysis of an Aircraft Jet Engine (AJE)

3rd International Energy, Exergy and Environment Symposium (IEEES-3) -- JUL 01-05, 2007 -- Univ Evora, Evora, PORTUGALWOS: 000261709300006This study deals with energy, exergy and exergoeconomic analysis of an Aircraft Jet Engine (AJE) as named J69-T25A used on T-37B/C model training aircrafts. In the analyses, the engine data measured in the engine test cell at First Air Supply and Maintenance Center of Turkish Air Forces are used. Quantitative exergy and exergoeconomic cost balance equations are derived for each components of the engine and the overall J69-T25A engine. Exergy destructions within the engine components are investigated to determine thermodynamic inefficiencies. Cost balances and auxiliary equations are also applied to each components of the engine for observing cost formation. Additionally, exergy cost rate and unit exergy cost rate of each products of the engine are accounted

Estimating and statistically analyzing the global solar radiation potential over big cities in Turkey

WOS: 000251627000004This study develops empirical models in order to estimate the monthly average daily global solar radiation on a horizontal surface (H). The seven big cities considered in the model have 33.4% of Turkey's population and are as follows: Izmir in the Aegean Sea, Samsun in the Black Sea, Ankara in the Central Anatolia, Van in the East Anatolia, Istanbul in the Marmara, Antalya in the Mediterranen Sea, and Urfa in the Southeast Anatolia Region of Turkey. The developed models were analyzed using the seven statistical analyzing methods such as the mean percentage error (MPE), mean absulate percentage error (MAPE), sum of squares of relative error (SSRE), relative standard error (RSE), mean bias error (MBE), root mean square error (RMSE) and correlation coefficient (R). It may be concluded that the present models estimate the values of H, reasonably well for the cities studied and possibly elsewhere with similar climatic conditions

Exergoeconomic analysis of a combined heat and power (CHP) system

WOS: 000254458000001This study deals with exergoeconomic analysis of a combined heat and power (CHP) system along its main components installed in Eskisehir City of Turkey. Quantitative exergy cost balance for each component and the whole CHP system is considered, while exergy cost generation within the system is determined. The exergetic efficiency of the CHP system is obtained to be 38.33% with 51 475.90 kW electrical power and the maximum exergy consumption between the components of the CHP system is found to be 51 878.82 kW in the combustion chamber. On the other hand, the exergoeconomic analysis results indicate that the unit exergy cost of electrical power produced by the CHP system accounts for 18.51 US$ GW(-1). This study demonstrates that exergoeconomic analysis can provide extra information than exergy analysis, and the results from exergoeconomic analysis provide cost-based information, suggesting potential locations for the CHP system improvement.
