In the beginning of 1973 in the USSR the study of possibility of LJE designing was conducted. The reflector, located in the tail of the rocket prototype, concentrated the obtained radiation in air and ensured micro-burst that the reactive thrust was created. The successful results of different models of the reflectors tests, which were at the same time the laser light receivers, had been obtained. One should note that all experiments pointed out above were conducted with the use of electric discharge CO2- lasers with power up to 10 kW, while for the injection into orbit of different highly and technologically effective equipment (global network connections, Internet, photo-monitoring of Earth surface, debris cleaning) the radiated power substantially higher is required. Thus, for example, for SC launching with the weight 1000 kg the laser with power not less than 15 MW is necessary [1,2].

Objective: This descriptive study was conducted in order to determine body image perception and life satisfaction of individuals undergoing hemodialysis treatment. Material and methods: The population of the study consisted of individuals who were treated in hemodialysis units in the city center of Kırşehir. Patients. The study was conducted with 135 patients. Questionnaire, multidimensional body-self relations questionnaire, and satisfaction with life scale were used as data collection tool. Results: According to study results, total mean scores of MBSRQ were significantly low in individuals who were older than 65, illiterate, had an extended family, were unemployed, had low income, suffered from disease and underwent hemodialysis treatment for 10 years and longer, had arteriovenous fistula in vascular insertion site, had body mass index within the class of morbid obese, and had no planned transplantation. SWLS mean scores of individuals, who were in the age group of 25-34 years, high school graduate, employed, described their income status as very high, had CRF for 6-12 months, underwent hemodialysis for 6-12 months, were waiting for renal transplantation, were significantly high. As a result of the correlation analysis made between body image and life satisfaction, it was determined that there was a positive, quite significant correlation Conclusion: As a result, it was determined that hemodialysis patients were affected by body image and life satisfaction negatively due to many factors and the total score of body image scale was very low.

From the energy involved in a physical or chemical process, part of it cannot be utilised as work. Entropy S is the thermodynamic quantity that is the measure of this energy where the concept of entropy was first introduced by Rudolf Clausius (1822-1888) in 1865. Entropy is also a basic and general conception that deals with “order” (low entropy) and “disorder” (high entropy) of all systems in the universe from human body and up to the star systems. With the development of science entropy deviates from treatment of subjects related to heat and work and currently it is used also to analyse knowledge as well as in economics. 

The natural ferromagnetic resonance (NFMR) in cast glass-coated amorphous magnetic microwires has been studied theoretically and experimentally. The NFMR reveals large residual stresses appearing in the microwire core in the course of casting. These stresses, together with the magnetostriction, deteRmine the magnetoelastic anisotropy. Beside the residual internal stresses, the NFMR frequency is influenced by external stresses applied to the microwire or to the composite containing the latter (the so-called stress effect). The dependence of the NFMR frequency on the deformation of the microwires is proposed to be used in the distant diagnostics of dangerous deformations of critical infrastructure objects such as bridges, dams, wind turbine towers, skyscrapers, stack-furnaces, embankments, etc. To this end, fragments of magnetic microwires will be embedded in the bulk of concrete structures or fixed on their surface during construction or after it by means of coating with a special concrete-adhesive plaster. Further, these structures are periodically irradiated with microwaves from a radar at frequencies close to the original NFMR, and the presence of latent dangerous deformations of the concrete structure is judged by the NFMR frequency shift.

Introduction: Physical activity (PA) directly affects Health-related quality of life. The aim of the study was to establish the relationship between physical activity levels of physiotherapists and their physical activity promotion strategies. in Hebron/West Bank. Method: The study relied on cross-section, which included 150 PTs distributed over 42 centers of Hebron areas in Palestine country. The questionnaire is based on Likert scale items pentagonal level, which included several aspects of Health-related quality of life. Statistical analysis was used to test the associations between different categorical variables (p < 0.05). Results: of total 150 participants, most of them were male 56%, their ages ranged from 25-30 years (46%), and holding bachelor’s degrees 78%. About 60% of them are in good physical health. Most participants feel vitality, depression, quit, have energy, and are happy in the most of the time. In addition, most of them believe their health is similar to that of the members of the surrounding community. The study showed there is no relationship between general health and age except in the age group over 40 years, and females are the most exposed group. In addition, there is an influence relationship between physical and psychological with age, and this effect also includes females more than males. Conclusion: Physical functioning of most of the participants was good, while most of the participants had problems with their work and the major effect was on the female category.

Aim: The purpose of this study is to assess the experiences of postgraduate students during wet-lab training with the aim of improving the course content and introducing evidence-based and student-centered changes. Methodology: The study made use of a cross-sectional design and data were collected using the qualitative research approach. Information was elicited from all the Senior Registrars who participated in the training through in-depth interviews. Result: All the postgraduate students who participated in the training were satisfied with the course content and the method of delivery appropriated during the training. They also found it relevant to their practice. However, certain shortcomings were observed such as high cost of training, poor standard of equipment/tools, tight work schedule and short training duration. Conclusion: Hands-on training plays an important role in enhancing the quality of care and high performance in health-care service delivery. The shortcomings and suggestions for improving future trainings as reported by the residents should be addressed in order to maximize the gains of the hands-on training experience

This study was carried out to investigate the rotational structure of even-even 166Hf isotopes using the phenomenological fitting, Sood’s semi-empirical formula. The rotational energies from the calculated values were compared to the experimental spectrum. The result shows that in 166Hf, calculated energies fit the experimental values to a remarkable degree of accuracy.

Introduction: Contact of health care workers and patient at health facility lead to the transmission of pathogenic organisms to each other. Hospital acquired infection prevention is standardized guide lines contain multitude protocols needed to be implemented by health care workers to reduce hospital acquired infections. Objective: To assess health care workers knowledge, attitude and practice towards hospital acquired infection prevention at Dessie referral hospital. Method: Institutional based cross sectional study was conducted among health care workers. The subjects were selected by proportional allocation in each respective department and simple random sampling method was employed. Statistical package for social sciences (SPSS) was used to analyze the data and presented in frequency tables and graph. Results: 191 study subjects were participated in the study which gives a response rate of 90.5% from 211 total sample sizes. The study subjects had given their response according to self-administered questioner. The result indicates that 86.4%, 76.4% and 77% of respondents had good knowledge and favorable attitude and poor practice towards hospital acquired infection prevention respectively. Conclusion: Even though the majority of the health care workers had good knowledge and favorable attitude, more than two third of them had poor practice towards hospital acquired infection prevention. Therefore health workers should strictly follow hospital acquired infection prevention guidelines. Improving sustainable supplies like personal protective equipment, water supply and hand washing facilities at patient care site is vital to correct the poor practice of infection prevention.

The measurement of the natural ionizing radiation in the Federal University of Technology Owerri, Nigeria was carried out using a well calibrated Digital Geiger Muller counter models GCA – 04w. Measurements were taken randomly in thirty (30) diff erent locations outside the building and thirty (30) locations inside diff erent buildings in the University. Results obtained for outdoor Dose rate ranges from 0.07 μSv/hr to 0.23 μSv/hr with a mean value of 0.144 μSv/hr. While the result for the indoor dose rate ranges from 0.08 μSv/hr to 0.21 μSv/hr with a mean of 0.14 μSv/hr. The highest value recorded for the outdoor radiation is from the university front gate which is .023μSv/hr. While the highest value recorded inside the buildings is from the School of Agriculture and Agricultural Technology (SAAT) which is 0.21 μSv/hr. All these values are lower than the world safely limits of 0.247 μSv/hr. This shows that the risk of ionizing radiation on the staff and students of the Federal University of Technology is minimal.

Background: The argument on whether extracorporeal shock-wave therapy (ESWT) is beneficial in short- term intervention in adults with plantar fasciitis. It is important and necessary to conduct a meta-analysis to make a comparatively more reliable and overall assessment of the outcomes of ESWT in the less than 6 months. Methods: We conducted a systematic review and meta-analysis of randomized control trials from MEDLINE, EMBASE and CINAHL databases from 2000 to 2020. Randomized trials that evaluated extracorporeal shock wave therapy used to treat plantar heel pain were included. Trials comparing an extra corporeal shock wave therapy with control/placebo were considered for inclusion in the review. We independently applied the inclusion and exclusion criteria to each identified randomized controlled trial, extracted data and assessed the methodological quality of each trial. Results: Four studies involving 645 patients were included. 3 RCTs (n = 605) permitted a pooled estimate of effectiveness based on overall success rate and composite score of visual analogue scales for pain at follow-up 1 (12 weeks). The pooled data showed no significant heterogeneity at the three-month follow-up (p - value of chi-square = 0.61, p = 0.74 and I2 = 0%). The shock wave group had a better success rate than the control group at the three-month follow-up (OR = 2.26, 95% CI = 1.62-3.15, p - < 0.00001). For reduction of pain the pooled data showed no significant heterogeneity (p - value of chi-Square 0.28 and I2 22%). There were significant differences between the ESWT and control groups for all follow-up visits (random-effect model, three trials, MD = 15.14, 95% CI = 13.86 to 16.42, < 0.00001 at three-month). Conclusion: A meta-analysis of data from three randomized-controlled trials that included a total of 605 patients was statistically significant in favor of extracorporeal shock wave therapy at follow-up 1(12 weeks).
