The influence of non-verbal body language on sport performance in professional tennis
Authors: Martínez-Gallego Rafael , Carrillo Molina David 
Published: May 2021

The main objective of this study was to analyse the relationship between players´ non-verbal body language and their performance in sport. The sample consists of a total of 477 actions from 40 players competing in the ATP Tour. All actions were taken from tie-breaks in official tournaments. The categories that were analyzed were previous performance, dominant non-verbal body language, submissive non-verbal body language, and performance later on. Results show how the players´ non verbal body language impacts on their performance later on. Thus, we can conclude that following dominant non-verbal body language, the probabilities of better performance in the next point are greater than following submissive non-verbal body language. Therefore, it is important to train these aspects as an extra tool to improve players´ performance.

THE EFFECT OF BETA - ARRESTIN 1 TRANSFECTION ON PROLIFERATION AND TEMOZOLOMIDE TREATMENT RESPONSE IN HGG CELLS
Authors: Horescu Cristina , Artene Stefan-Alexandru 
Published: May 2021

While several studies have indicated a major role of the ?-arrestin family in the development of several types of cancer, little to no information is available on its influence in malignant gliomas.
In our study we transfected an established high-grade glioma cell line, 11 HGG with a ?-1 arrestin plasmid in order to observe how ?-1 overexpression influences proliferation and response to standard of care treatment. After 24h, the transfected cells presented a drop in proliferation when compared to untransfected cells. In terms of treatment response, transfected cells presented a markedly elevated cytotoxic effect when compared to untransfected cells. However, after 48h and 72h transfected cells presented only a minor increase in proliferation while treatments responses to TMZ were modestly influenced by ?-1 arrestin overexpression.

ABSTRACTThe task of a Christian Religious Education teacher is not just to teach and prepare teaching materials, but a teacher is required to be able to create active, creative learning interactions and be able to design fun learning. Christian religious education teachers are not only tasked with transferring factual and conceptual knowledge to their students but Christian religious education teachers must think about how students can receive messages in their teaching and learning process. One of the reasons the learning process did not go as expected by the teacher was due to the inaccurate selection of teaching methods in the teaching and learning process. It cannot be denied that teaching methods also affect the ability of students to absorb learning material. Learning will be fun if the Christian Religious Education teacher chooses and uses various teaching methods in their teaching assignments. The research approach used is a descriptive approach, namely methods and research procedures that are Research Library by utilizing information sources from books and journals. This study aims to describe the implications of Christian religious education teaching methods for Christian religion teachers.Keywords: Christian Religion Teachers, Christian Religious Education, Teaching Methods.

Living on the Other Side: A socio-legal analysis of family law and migration in Morocco
In our research project ‘Living on the Other Side’, we aim to understand how (ir)regular migrants from the Middle East and West/Central Africa deal with the legal and formal aspect of their lives in Morocco by focusing on major life events, such as marriage, divorce, birth and death. Life does not simply stand still when residing in a foreign country – people continue to marry, divorce, have children and die. However, there is little empirical knowledge on what migrants actually do when faced with such events. Registering major life events secures a migrant’s legal identity and protects their human rights. Having a legal identity, most likely, influences the daily lives of migrants. A migrant, who does not formally exist in the eyes of the state, might not be able to access basic services, like health care and education. From a legal pluralist perspective, we aim to investigate how migration and family law intersect by conducting online and offline ethnographic fieldwork.
Technical and biological causes of periapical surgery: Retrospective analysis of 301 apical surgical cases
Authors: Ekici Ömer 
Published: May 2021

Aim: Endodontic surgery is a treatment for persistent peri-radicular pathological conditions that do not improve after endodontic treatment. The aim of this study was to evaluate the quality of endodontic treatment, technical error types seen in root canals and the periapical condition of the teeth in patients undergoing periapical surgery, and thus to analyze the reasons leading to periapical surgery.
Methodology: Clinical and radiographic data of 301 periapical surgery cases were retrospectively evaluated in this study. The causes of periapical surgery were classified into technical and biological reasons.
Results: In this study, 51.8 % of periapical surgery cases were related to biological factors and 48.2 % were related to technical factors. Maxillary anterior teeth were the most common teeth undergoing apical surgery with a rate of 66,8 %. The most common technical reasons were non-homogeneous filling (15,6 %), underfilling (12,0 %) and overfilling (9,6 %). The most common biological reasons were cysts (30,2 %), traumas (16,6 %) and apical abscess (5,0 %). 37.5% of cases undergoing periapical surgery, the diameter of the cystic lesion was 10mm or more.
Conclusion: The number of cases of apical periodontitis is increasing in the community due to insufficiently filled root canals. Increasing the quality of root canal treatments applied by dentists will reduce the need for periapical surgery by reducing the incidence of apical periodontitis.

Mikrovyučování jako prostor pro implementaci vrstevnického hodnocení do přípravy studentů učitelství
Authors: Rokos Lukáš 
Published: May 2021

Příspěvek propojuje dva fenomény přípravy studentů učitelství. Jedním z nich je užití mikrovyučování při oborových didaktikách a druhým je užití vrstevnického hodnocení. V rámci mikrovyučování při didaktice přírodopisu a biologie si 66 studentů učitelství navzájem hodnotilo svůj výkon. Nástrojem, který jim k tomu pomáhal, byl strukturovaný hodnoticí formulář obsahující pět škálových položek a tři otevřené položky. Ukázalo se, že studenti učitelství nemají problém hodnotit na škálových položkách, ale slovní zpětnou vazbu poskytují již méně ochotně. Z analýzy poskytnutých zpětných vazeb bylo zjištěno, že nejčastěji se hodnotitelé zaměřili na jazykový projev studenta, způsob aktivizace a probuzení zájmu žáka o učivo. Dále si všímali vhodnosti navržené aktivity k věku žáků. Pozitivním zjištěním byl fakt, že se ve zpětné vazbě nijak neprojevovaly osobní vztahy mezi studenty. Komentáře s formativním charakterem se ve zpětné vazbě příliš často nevyskytovaly, ale v případě, že hodnotitel poskytl formativní zpětnou vazbu, tak byla správná a poskytovala hodnocenému studentovi důležitou informaci.
Developments in the IMS VPP Formulations
Authors: Claughton Andrew 
Published: May 2021

The paper describes the improvements made to the aerodynamic and hydrodynamic force models of the Offshore Racing Council (ORC) International Measurement System (IMS) sailing yacht velocity prediction program (VPP) since 1990. The paper explains the mechanisms of the force modeling used in the IMS VPP to provide a framework within which the modifications and revisions to the VPP are described. The major revisions fall into three categories.
1) The hydrodynamic model, where a revised formulation for residuary resistance and characteristic length has been introduced, which includes modifications to both the residuary and viscous resistance components. Revisions to the drag due to heel and induced drag formulations are described that more accurately reflect the behavior observed from towing tank tests.
2) The added resistance in waves module was introduced to assist with the equitable handicapping of diverse bull types and construction methods, which affect the behavior of sailing yachts in waves. The mechanism by which the sea state is charaterised and the added resistance calculated is described.
3) The aerodynamic force model, which derives complete rig lift and drag coefficients from standard sail types is described. The behavior of the VPP force model is compared with wind tunnel test results, and the recent additions of coefficient sets for a range of different sail types is described. Finally the components of a more detailed model of hull and rig windage are outlined.
The Effect of Bow Steepness and Flare on the Resistance of Sailing Yachts in Calm Water and Waves
Authors: Keuning J. A. , Onnink R. , Damman A. 
Published: May 2021

In this paper some results are presented of two studies carried out at the Ship hydromechanics Department of the Delft University of Technology: one, on the influence of an increase of stem steepness of a sailing yacht, and another, which was largely carried out by T.J.E. Tincelin as part of his master thesis at Delft University of Technology, on the effect of above waterline bow flare are presented.
To investigate the influence of bow steepness a model of the Delft Systematic Yacht Hull Series (DSYHS) has been used as a parent model of a new small subseries with two additional derivatives each with increased bow steepness. The influence on both the calm water resistance and the added resistance in head waves has been investigated.
To investigate the influence of bow flare, two models of a typical "Open 60" design have been used: one "normal" and one with almost no flare in the bowsections. These have been tested in calm water and in both head- and following­waves to investigate the effects of this difference in bow shape on the calm water resistance, on added resistance in waves, and on the relative motions at the bow. The results are presented and some comparisons with calculations made. Also some general conclusions with respect to resistance, performance and safety are drawn.

Published: May 2021

Los problemas de bajo rendimiento académico y rezago son recurrentes en instituciones educativas de nivel superior, especialmente al inicio de los estudios universitarios. En el contexto local, análisis diagnósticos han mostrado altos índices de reprobación y bajo rendimiento académico. En este trabajo, se utilizaron datos sociodemográficos y resultados de exámenes de admisión de 415 alumnos de las carreras del área de computación de la Universidad Autónoma de Yucatán (México), inscritos entre 2016 y 2019. El objetivo es generar modelos predictivos de riesgo académico, empleando métodos de la minería de datos educativa, que sirvan como herramientas de detección temprana de condiciones de riesgo académico y faciliten el despliegue de estrategias de intervención educativa. Se siguieron las etapas del Proceso de Extracción de Conocimiento en Bases de Datos, concretamente, se aplicaron técnicas de clasificación para el análisis, obtención y validación de los modelos. Los resultados muestran que el mejor modelo corresponde al algoritmo LMT, con un valor de precisión de 75.42% y un 0.805 para el área bajo la curva ROC. Se logró identificar a los mejores atributos predictores, particularmente las pruebas del examen de ingreso a licenciatura fueron muy significativas. Se propone el desarrollo de herramientas informáticas para la detección precoz de riesgo académico y estrategias de intervención educativa oportuna.
The problems of poor academic performance and lag are recurrent in higher-level educational institutions, especially at the beginning of university studies. The early detection of academic risk conditions enables the implementation of educational intervention measures to address factors of poor school performance, associated with the particular contexts of the students. The purpose of this study was to generate predictive models of academic risk, using educational data mining methods, specifically classification or prediction techniques, for the analysis, obtaining and validation of the models. The data used correspond to admission exam results and sociodemographic data of 415 students of the computer science majors at the Autonomous University of Yucatán (Mexico), enrolled between 2016 and 2019. The results show that the best model corresponding to the algorithm of LMT classification, with a precision value of 75.42% and 0.805 for the area under the ROC curve. It was possible to identify the best predictive attributes, particularly the bachelor entrance exam tests were very significant. The development of computer tools for the early detection of academic risk and strategies for timely educational intervention is proposed.
Hospital-based case control study and animal study on the relationship between nonylphenol exposure and depression

Published: May 2021

Objectives
The aim of this work is to explore the association between chronic exposure to nonylphenol (NP), a representative environmental endocrine disruptor (EED), and the risk of depression and its potential mechanism.

Methods
A hospital-based case control study was conducted from August to December 2018. Forty-one patients with confirmed depression and 47 healthy volunteers were recruited. In vitro, 20 rats were randomly divided into the control group (corn oil) and NP exposure group (n = 10 per group), which were gavaged at a dose of 4 mg/kg w/day for 180 days.

Results
The depressed patient group had higher Zung Self-Rating Depression Scale (SDS) (P < 0.001) and Self-Rating Anxiety Scale (SAS) (P < 0.001) scores than the healthy group. The serum NP level (P = 0.009) in the depressed group was higher than that in the healthy group, and the BDNF level (P = 0.001) was lower. The serum levels of monoamine neurotransmitters dopamine (DA) (P = 0.070), epinephrine (E) (P = 0.001), and noradrenaline (NE) (P = 0.000) were lower than those in the healthy group. In the sucrose preference test, the sucrose preference time for the exposure group of rats was lower than that of the control group (P < 0.001). In the forced swim test, a longer resting time was measured for the exposure group of rats as compared to the control group (P < 0.05). The level of NP (P < 0.001) in the brain tissue of the NP exposure group was higher than that in the control group, and the serum level of brain-derived neurotrophic factor (BDNF) (P = 0.004) was lower. Histopathological examination of the brain biopsies illustrated that the neuronal cells and nuclei in the hippocampus of the exposed group exhibited slight shrinkage.

Conclusion
Chronic exposure to NP at environmental doses will result in the accumulation of NP in the brain and blood, and induction of depression, which might be associated with the alterations in the expression levels of BDNF and monoamine neurotransmitters.

Mushroom cultivation is one of the most important steps in diversification of agriculture. Milky mushroom (Calocybeindica) is a tropical edible mushroom, popular because of its good nutritive value and it can be cultivated commercially on large scale. Generally, by creating controlled environment in rooms mushroom cultivation is taken up, In traditional method it is typical to manage the atmospheric temperature and humidity in desired range, which can be maintained easily in greenhouse by automatic control system.Cultivation of milky mushroom in greenhouse was taken up in controlled environment under three different conditions of controlled temperature and relative humidity (RH). The experimental conditions are 28°C and 79% RH, 24°C and 84% RH and 32°C and 72%RH. The yield obtained was found maximum at 24°C temperature and 84% relative humidity when compared with the other two greenhouse environment conditions. The yield from the mushroom cultivation under controlled environmental conditions in greenhouse was found to be high when compared with the conventional practice. It was concluded that, the mushroom cultivation yields high under controlled greenhouse conditions and also economical compared to the conventional method.
