Low back pain (LBP) in adolescent athletes may lead to a significant lost playing time and thus reduce their performance and compromise their career. The aim of our study was to determine the one-year prevalence of LBP and its associated factors in adolescent athletes. Methods: A cross-sectional study including adolescent athletes from a Tunisian athletics club. LBP prevalence and circumstances were noticed. Training characteristics and flexibility of the lumbar spine and lower extremities were ...

Electricity is transmitted from the generating stations to the distribution center and consumers through transmission lines, to ensure that energy reaches consumers in the required form and quality, and losses along transmission lines must be minimized. In this project, losses were analyzed and reduced in the East network sector (66 kV) using a modern compensator Static VAR (Volt-Ampere Reactive) Compensator (SVC) and electrical network simulation in the NEPLAN program to validate its validity. ...

The distinction between the concepts of a Necessary Condition and a Sufficient Condition is a fundamental element of mathematics. This issue certainly applies to physics which has a mathematical structure. However, this work shows that sometimes physical textbooks ignore this distinction. An analysis of the conserved 4-current of the Noether theorem proves that this issue is extremely important. The analysis uses the dimension of the Lagrangian density and the corresponding dimensi...

This study highlights the of wood chip on the physical and mechanical characteristics of concrete. The objective is to promote iroko wood chip in the construction sector. The aim is to incorporate chip into concrete and to study its influence on the physico-mechanical properties of concrete. To conduct this study, the materials used were first characterized. Secondly the concrete was formulated and the concrete specimens were poured. Finally, the physical and mechanical characterizations of conc...

This paper attempts to express the golden ratio numbers with nucleotide bases (A T, G, C and U) as regards to Quantum Perspective Model. At first, if you take the exact value of golden ratio numbers after the comma, you can convert these decimal base numbers to binary number base system. Secondly, after converting process of these numbers, you should sequence these numbers as decimal number base system again. Thirdly, sum these decimal base numbers respectively. Fourthly, total adding processes ...

Many marketing and economic studies have discussed the main determinants of the price in the market. However, to the best of our knowledge, few studies have addressed how the price could be determined in second-hand shopping. Studies have concluded that the duration of ownership has a significant positive relationship with the value of the object. This paper argues that such a relationship depends on the experience of using the object (either positive or negative). It argues that ownership durat...

Japan’s animation industry has developed in the past half century. Toei Animation, which was established in 1956 and symbolizes the beginning of the Japanese animation industry, put forward the goal of becoming the Disney of the East at the beginning of its development, showing its ambition to challenge the Western Disney with the image of the East under the perspective of the East-West dichotomy. This paper takes this East-West perspective as a clue and discusses the characteristics that Japane...

Development of drug-resistant lines in rodent malaria parasites left us a deep impression on antidrug specificity of antimalarial drug-resistant lines, which is similar to antigen-induced antibody. Based on this comparison, “specific antidrug substance” was proposed to explain antidrug specificity of drug-resistant lines. If “specific antidrug substance” refers to a protein that is quite like antibody, the concept of “specific antidrug substance” is wrong because no such protein has been discove...

The resource potential of the Triassic Yanchang Formation’s Chang 6 reservoir in the southeastern part of the Ordos Basin’s slope is large, whereas it is poor levels of exploration, and reservoir evaluation is not perfect enough, so that, limiting future exploration in this area. It is underpinned by core of detailed observations and descriptions of the Chang 6 reservoir system, typical samples of various sample, oil-bearing properties, and sedimentary structures were collected, and further anal...

Introduction: Intrapericardial teratoma is a rare tumor usually diagnosed in newborns, generally affecting children under one year old. We report a case in an infant revealed by cardiac tamponade. Observation: This is a male newborn, 3 weeks old, with no notion of parental consanguinity. The pregnancy was followed with 4 prenatal consultations, no particularities on the assessments carried out, no ultrasound done, and was born vaginally after 37 SA 3 days. He shows good psychomotor development...
