Entropy generation of MHD flow of sodium alginate (C6H9NAO7) fluid in thermal engineering

In this paper, impacts of magnetic field and porosity on the entropy generation of sodium-alginate (C6H9NaO7) fluid are studied. C6H9NaO7 is taken over a moving and heated vertical wall. Heat transfer is due to free convection. Initially, the problem is formulated in the form of PDEs along with physical conditions and then written in non-dimensional form. Problem is solved via Laplace transform and expression in analytical form is established for temperature and velocity field. The related relations for entropy generation and Bejan number and entropy generation are also examined. Nusselt number and Skin-friction are calculated and plotted in graphs. For numerical computations, a finite difference scheme is used using MATLAB software. The results in tables and graphs are discussed for embedded parameters. It is found that the magnetic field and porosity have strong influence on velocity, entropy generation and Bejan number. For greater Hartman number, entropy generation magnitude is greater compared to the Bejan number, conversely, this variation in Bejan number is more efficient. The porosity effect showed that if the medium is more porous, the entropy generation can decreases 50% when porosity increase from Ka = 1 to Ka = 2, however the Bejan number increases.

The Effect of Electric Energy Accumulation by Hydrated ZrO2 – Nanoparticles

The dimensional effect of the accumulation of an electric charge with a density of up to 270 μF/g by the system of compacted zirconium dioxide nanoparticles during exposure in an electric field (5000 V/m) under normal physical conditions is determined. Based on a qualitative complex analysis of the forms of appearance of the effect, it is shown that the place of localization of different charge carriers is the surface of nanoparticles. The supposed mechanism of this effect is considered using the theory of dispersed systems, the band theory, and the theory of contact phenomena in semiconductors. It was concluded that this mechanism is due to the phenomenon of localization of electron-type charge nanoparticles in the near-surface zone of the material in contact with the adsorption ion atmosphere. This effect is relevant for modern nanoelectronics, microsystem technology, and printed electronics.

How Do Avalanche Dogs (and Their Handlers) Cope with Physical Exercise? Heart Rate Changes during Endurance in a Snowy Environment

This study aimed to assess the heart rate (HR) responses of avalanche SAR dogs and handlers under working field conditions. Thirteen SAR units (dogs and handlers) performed an exercise (Endurance) consisting of approximately 5.5 km of rough tracks through deep snow, at an altitude of 1991–2250 m.a.s.l. The exercise was repeated twice for each of the two different tracks. Both handlers and dogs were equipped with a global positioning satellite/heart rate (GPS/HR) system (Polar®). Multivariable models were used to evaluate the effects of environmental (i.e., gradient, altitude, track, and time) and intrinsic (i.e., speed, repetition, and breed) factors on changes from baseline HR (Δ%HR). The dog’s Δ%HR was greater in the flat and uphill compared with downhill, and increased progressively as the speed increased (p < 0.001). Moreover, it rose at altitudes above 2100 m.a.s.l. and peaked after 30 min of the Endurance activity (p < 0.01). These findings indicated that HR monitors could be a valuable tool to contribute to the evaluation of avalanche dogs’ fitness in their real working environment. In contrast, the lack of correlation between the dogs’ and handlers’ HR changes suggests that handlers might not perceive the physical conditions of their dog in real-time. Thus, implementing protocols to monitor avalanche SAR dogs’ fitness using a GPS/HR monitoring system could help handlers to tailor the training and workload and to detect the risk factors for physical distress of working dogs.

A COMPARATIVE CLINICAL TRIAL ON EGG YOLK BASTI & VIDARIKANDADI GRANULES IN CHILDHOOD KARSHYA

In this modern era of changing lifestyles, people and children cannot follow the rules of Dincharya and Ritucharya. Children have insufficient nutrients due to irregular food habits, which are triggering factors that cause childhood Karshya, resulting in mental and physical conditions that will not adequately develop. Biological and mentally healthy children are vital parts of a well-developed Nation, and this can be done by supplying nutritional requirements. The research was conducted in Bal Rog OPD, SAC and Hospital Lucknow. In this clinical trial total of 50 patients were selected and divided into group A and group B, having 25 in each group. Group A was treated with Egg Yolk Basti, and group B was treated with Vidarikandadi Granules for three months. In group A, 14 (56%) patients were relieved, 7 (28.0%) patients were moderately improved, 3 (12.0%) patients were mildly improved, and one patient did not show any response. In group B, 13 (52%) patients were relieved, 8 (32.0%) patients were moderately improved, 3 (12.0%) patients were mildly improved, and one patient did not show any response. This study indicates that Egg Yolk Basti and Vidarikandadi Granules can be effective in childhood Karshya.

Floatation Therapy for Physical Conditions

The clinical effectiveness of floatation therapy for the treatment of physical conditions remains uncertain. One randomized controlled trial was identified that evaluated floatation-restricted environmental stimulation therapy (REST) compared with placebo and waitlist control groups for the treatment of patients with chronic pain. The trial reported no significant differences between the 3 treatment groups on any of the outcomes measured including those related to pain, medication use, quality of life, sleep impairment, anxiety, or depression. One guideline was identified that states that there is insufficient evidence to recommend for or against the use of sensory deprivation tanks in patients with symptoms attributed to mild traumatic brain injury. The cost-effectiveness of floatation therapy for the treatment of physical condition is unknown as no relevant economic evaluations were identified.

Analysis of Accessibility to Family Health Centers in Antalya Using GIS

Family health centers in Turkey started to be implemented for the first time in Düzce in 2004 years within the scope of Law No. 5258. While determining the physical conditions of the places where family health centers are built, the first item in the regulation is that the building should be easily accessible. This situation shows the importance of the subject in terms of accessibility. While determining the features of the places where FHCs will be made, environmental characteristics are also taken into consideration. Environmental features are effective in determining the FHCs location in different ways. These impacts are divided into two groups: the physical features that pavements, roads and parks can include, and the social, cultural and institutional features of neighborhoods that include local social ties and collective activities. From this point of view, the importance of the location of family health centers relative to roads and houses is understood. The aim of this study is to examine the accessibility of Family Health Centers in Konyaaltı, Antalya, on a neighborhood basis using Geographic Information Systems. Konyaaltı has 21 Family Health Centers. As a result of the analyses, it was determined that most of the neighborhoods had problems in terms of accessibility, while a very few of them did not experience problems in terms of accessibility. In terms of the total number of buildings, the ratio of buildings that are 500 meters walking distance from any family health center by using highways is 35.56%. With these rates, 3,634 of the 10,2018 buildings remain within the limits of the regulation. Finally; suggestions were made to increase accessibility to these areas.

Coaching Clinic Basic Movements and Dominant Physical Conditions for Athletes at Gemilang Raya FC

Basic movements and dominant physical conditions are often still a problem for soccer players in supporting the strategies and tactics of a coach in building attacks or in defense, especially at Football Club Gemilang Raya Kuningan. Some players still have shortcomings in carrying out correct and accurate basic movements and do not yet know the physical procedural requirements that a professional soccer player must possess. Based on the problems faced, the STKIP Muhammadiyah Kuningan Service Team carried out activities to overcome the problems faced by partners. Community service activities aim to improve the abilities and skills of Football Club Gemilang Raya Kuningan athletes in performing basic movements and knowing the dominant physical condition. The activity was carried out at the Gemilang Raya Kuningan Football Club and was attended by 20 players. The method used is a coaching clinic which consists of 2 sessions. The material provided consists of understanding basic movements and dominant physical conditions, practice on basic movements and dominant physical conditions. The results of the activity to the community showed an increase in the abilities and skills of Football Club Gemilang Raya Kuningan players regarding basic movements and dominant physical conditions.
