Physiological, morphological characteristics and blood profile of female elite Brazilian soccer players according to position

The main goal of this study was to identify the performance parameters and blood profile found among female soccer players. The second aim was to examine if there were any systematic differences between players assigned to different playing positions. Thirty-six players (age: 23.7 ± 3.5 y; weight: 61.9 ± 5.7 kg; height: 165.7± 6.2 cm) underwent a set of laboratory tests (cardiopulmonary exercise test, skinfold measurements, Wingate test, sit-and-reach test, and blood biochemical tests). The following results were verified: maximal oxygen uptake (53±3.9 mL.kg-1.min-1), second ventilatory threshold (11.5 ± 0.8 km.h-1), body fat (14.1 ± 2.9%), Wingate anaerobic test (peak power: 9.5 ± 0.8 w.kg-1; mean power: 7.3 ± 0.4 w.kg-1 and fatigue index: 55.5 ± 4.9%), flexibility test [sit-and-reach] (18.1 ± 2.9 cm) and biochemical parameters of blood (Hb:13.9 ± 0.3 g.dL-1; iron: 85.2 ± 12.6 µ.dL-1; calcium: 9.2±0.5 mg.dL-1; total cholesterol: 204.7 ± 34.7 mg.dL-1; HDL-c: 50.7± 3.6 mg.dL-1; LDL-c: 125.8± 23.3 mg.dL-1; triglycerides: 96.8±18.5 mg.dL-1). In conclusion, the current results indicate that present elite players' physiological characteristics are similar to those previously shown, despite the rapid changes of the female soccer game worldwide. However, data showed that different playing positions had different physiological and anthropometrics differences.

The offer of corporate social responsibility and business ethics courses in university accounting undergraduate programs: A comparative analysis among administrative sciences

Business failures in the 1980s, in the United States, have prompted the undergraduate programs of Business Administration, Public Administration, Foreign Trade, Accounting and Auditing, Economics, Finance, Management and Leadership, Human Talent Management, Transportation Management, Business Management, Marketing, International Business and Tourism to strengthen the techniques and processes of education of the future professionals, based on the teaching of social responsibility and ethics. Hence, the main purpose of this research is to analyze the presence of subjects related to Business Ethics and Corporate Social Responsibility (CSR) at Universities and Polytechnic Schools that are within the National Public and Private classification, and which receive allocations and revenues from the State in Ecuador. For this purpose, null hypotheses (Ho) and alternative hypotheses (H1) have been proposed, obtaining significant statistical evidence in the analysis of 89 curricula of administrative science programs. The analysis shows that the offer of the 47 studied subjects of social responsibility, and 75 of ethics does not depend on whether the university is public or private to receive allocations and revenues from the State, but it does depend on the type of program or degree that is being offered. These higher education subjects are important to help, the future professional, remember his or her correct behavior, commitment, and actions in the company, in society, and in the environment.

Challenges in doctoral supervision in South African universities

This article addresses the challenges encountered by doctoral supervisors as they interact with their doctoral students in the contexts of South African universities. In a qualitative study of seven doctoral (PhD) supervisors and six PhD students, data was collected using interviews to examine the challenges supervisors experience as they supervise doctoral students. The PhD students were included in this study in because their responses would confirm or refute supervisor's views/opinions that emanated from their experiences in a social, cultural, and political context. Data analysis showed that doctoral supervisors experienced multiple challenges including overworking, time, and a set of academic characteristics of PhD students. Overall, the results of this study suggest that certain aspects among doctoral students who have completed doctorates in South African context, and their supervisors in different parts of the world would provide a starting point in the understanding of the implications of these aspects and their effect on the selection of doctoral students and the ongoing research in doctoral supervision in the South African context. doctoral supervision.

Effect of body movements in the venous blood flow and lymphatic circulation

The studies of ballistocardiography about the effect of cardiovascular activity in body motion raised the author interest in the research of the influence of body movements in the circulatory flow in venous and lymphatic vessels. These effects follow Sir Isaac Newton laws. With the body movement, the one-way valve structure of these vessels will cause a mobilization of venous blood and lymph to the proximal side. A model was built to demonstrate the effect of oscillatory movement in a liquid flow in a system of one-way valve. There was a rise of the liquid with difference in level that ranged from 9 cm up to 34 cm, depending on the amplitude and frequency. The model tried to mimic a segment of vein with its valve, and evaluate the effectiveness of oscillatory movements in the progression of the liquid, In a preliminary study, to assess the effect of oscillatory movements on leg swelling, this movements was applied in a clinical cases. There was regression of the oedema and circumference on the leg, by oscillatory movements, that was correlated with increase in lymphatic and venous drainage. Venous stasis is a predisposing factor of venous thromboembolism. How we extrapolate from the experimental model, the oscillatory movements of the legs improving venous circulation may contribute to the prophylaxis of venous thromboembolism. In conclusion, it is of interest to study its application in some situations of venous thromboembolism risk.

Thermoelectric generators

As the world is changing and developing with every passing day, the requirements of power are also increasing. There is a shift in utilizing the electrical energy as much as possible and for this reason, many countries have already made policies for completely ruling out the machines which don’t run on electricity. Apart from electricity, there are other forms of energy that can be used to convert that form into a more desirable form. For example, in a plant where the smoke comes out of the chimneys or in a car, the smoke carries a large amount of thermal energy with it. This energy is nothing but a waste and reduction in the efficiency of the systems. If somehow, this energy could be recovered, the efficiency can be increased. Thermoelectric generators serve for this purpose. Thermos electric generators get the heat and using the principle of heat conduction and p and n type materials, the heat can be directly converted into the electricity. There are many materials available in the market for p and n type but in our case, we chose silicon germanium which is also one of the most commonly used. First of all, a single module of thermoelectric generator will be made using p and n type material, as well as using conductive material and some ceramic substance. Then, the entire assembly will be made and this assembly will be exported to Ansys where custom materials will be added and applied on to the geometry. After performing analysis on full model, a comparative study will be presented in which the effect of material of conductive plate on to the voltage difference will be studied

Overview of the change in the organization of the education system in Gabon

The question of change in the organization is at the heart of the concerns of public policy managers. This article proposes to analyze the management of organizations in the educational system in Gabon. We have examined what is said and what is best done in the field in an attempt to identify this consideration by the theorists of change. As pointed out by several authors, particularly those who have investigated this issue, change is a stakeholder in the management of organizations. At the end of this literature review, we found that Gabon is not the only country to be confronted with the problem of change management in its education system. In conducting an education reform, it must take into account the balance of power within the organization. In order for the organization to achieve its goal, communication must become a permanent feature of human resources management. Thus, changing the education system is a titanic but achievable undertaking. The competence of the managers, the piloting mode and the management of human resources are determining factors in the process of change.

Behaviors of Yahisuli’s Parents in Early Childhood Immunization in 2018

This descriptive cross-sectional study aims to determine factors associated with Yahisuli's parents' behaviors in early childhood immunization in 2018. To collect data, we used a questionnaire administered to a non-probability convenience sample of 96 parents of children 0-11 months of age. Descriptive analysis allowed us to compare our results with previous work. We recorded an average age of 32.8 years and a male/female sex ratio of 1.3. More than 95% of the parents went to school, of which 58.5% have a high school education. The birth rank of the last child ranged from 3 to 5 with a sex ratio of 1.3 in favor of males. Nearly 15% of children have not been fully vaccinated. In this work, 55 out of 96 parents bring their children to a health facility to be vaccinated to ensure their protection (76.4%) and prevention against infectious diseases (47.3%). On the other hand, 42% do not adhere to vaccination because of ignorance, fear due to children's incessant crying after vaccination, adverse post-immunization events. When it came to vaccines, several misunderstandings were raised. These corroborate rumors observed under other skies. Thus, a descriptive and analytical study on the epidemiological surveillance of adverse effects of vaccines is indispensable in the province of Tshopo.

Sexual dimorphism of viscerocranium-A logistic model

Introduction: Sex estimates are generally based on the evaluation of qualitative and quantitative aspects of anatomic structures, however, the latter has better reproducibility and reliability. Objective: Aiming to evaluate the viscerocranium as a tool for sexual prediction and verify the possibility of creation of a logistic regression model for sexual prediction. Materials and Methods: 167 craniums - 100 male and 67 female between 22 and 85 years old from a Brazilian university´s Biobank - were evaluated. Results: It was observed that of the measures carried out were presented as sexually dimorphic, except for the measures of the right frontozygomatic point – right zygion; left frontozygomatic point – left zygion. Besides, it was possible to create a logistic regression model Sex = [logits/Sex = -24.5 + (0.20 * Nasion - Naso spine) + (0.18 * Right zygion - Naso spine)]. Conclusion: It was concluded that the measures of the viscerocranium present themselves as a factor of sexual dimorphism and the quantitative method developed was 81.4% accurate.

Middle East’s circular economy expectations for the next ten years

This study provides an overview of waste management through circular economy in Middle East. Waste management has become a worldwide problem since humans are wasting resources as well as raw materials. This is the biggest problem faced by the humans on Earth that is getting attention of government representatives from all over the world. Recently, Middle East has also showed concerns regarding the amount of waste produced. Thus, several government representatives of Middle East have voiced their opinions and have taken an initiative to adopt this model. This article is based on the adoption of the model of circular economy in the countries of Middle East. This article explains the challenges that Middle East needs to be aware of for successful implementation of this model.

Placing greater emphasis on vocational education in Kenya

Kenya, like other countries in the Sub Sahara Africa (SSA), Technical, vocational education, and training (TVET) is believed to be an obvious remedy to youth employment across the region. As we view TVET in this way, the perception in many if not all the countries across SSA is that TVET is a salvation for the intellectually incapable or those with less or no aspiration for better paying jobs. For the elite and middle class, TVET is in reality not for their children, as it seems almost ‘useless’. Interestingly, even with such perceptions, Kenya and other SSA countries have continued to ‘embrace’ TVET in their education systems but with little investment towards those TVET programmes. In 2018, there was a shift in policy in Kenya with TVET receiving more attention, and as a result attracting a larger budget allocation. The government slashed fees for students in technical and vocational education institutions, and raised public funding in its latest bid to grow the critical skills base needed to achieve the country’s economic ambitions. To support this policy, the government agreed to give an annual bursary of US$300 for every student who joins the technical institutions (University World News, 2018). The students will access the funding through the Higher Education Loans Board (HELB), the agency that disburses loans to university students on behalf of the government. This policy comes as a result of the World bank warning regarding a widening disconnect between labour market skills needs and the graduates of higher education institutions. This paper provides an overview of the state of TVET in Kenya, challenges and possible recommendations to support the new TVET reforms towards making it more attractive for learners in Kenya.
