Published: December 2020

Este artigo de revisão traz pela primeira vez para a literatura brasileira discussões mais aprofundadas sobre as características físico-químicas dos produtos da pirólise de pneus inservíveis e suas aplicações. As propriedades físico-químicas e distribuições dos produtos, resultantes da pirólise (sólido - char, gasoso – syngas e líquido - óleo pirolítico), foram discutidas, com relação às variações das condições de pirólise. Na revisão é mostrado que as interações das variáveis do processo de pirólise também influenciam na ocorrência de reações secundárias, as quais interferem na distribuição dos produtos. Os produtos gasosos e líquidos, obtidos da pirólise de pneus inservíveis, foram apresentados como uma valiosa fonte de combustível para a geração de calor e energia elétrica. O sólido pirolítico, além da utilização como combustível sólido, tem potencial para a recuperação de negro de fumo e utilização como adsorvente, após processo de ativação. Atualmente, o produto líquido de pirólise tem recebido maior atenção dos pesquisadores, dada a sua flexibilidade em termos de armazenamento e transporte, seu alto conteúdo energético, sua possibilidade de recuperação dos hidrocarbonetos e propriedades como combustível alternativo em motores de combustão interna.

Published: December 2020

In this study merchant vessel accidents which occured between 2001 and 2016 in the sectors of Türkeli, Kandilli, Kadıköy, Marmara which constitutes Istanbul Strait region under Istanbul Vessel Traffic Services scope have been examined. Data was obtained from database of Ministry of Transport and Infrastructure Main Search and Rescue Coordination Center, and after data cleansing process, 535 vessel accidents which involve merchant cargo vessels of above 500 grosston have been analyzed. Merchant cargo vessel accidents which were taken place in the specified sectors have been examined with CHAID (Chi-square Automatic Interaction Detector) Decision Tree method. CHAID Decision Tree method is one of the most common used decision tree algorithms in extracting meaningful rules from big datasets and for classification. Through conducting CHAID Decision Tree method for merchant vessel accidents relationship between accident type (collision/contact, grounding and other) and vessel factors (vessel type, Length overall (LOA), vessel gross tonnage, vessel age, flag, loading condition), time factors (accident time, season of accident) and other factors (sector where accident occured, pilot on board or not) has been analyzed. Accident occuring sector, pilot on board/not, vessel type and accident time have been found as the most important input variables. Based on the result of the Decision Tree method applied to the data set, it was observed that the accidents occurring in the Kadıköy sector were collision / contact with 86% probability, the accidents occurring in the Kandilli or Marmara sectors were collision / contact with 48% probability and in the Türkeli sector, both collision / contact and other accident types had 36% occurring probability.

Authors: Söyler Nazlı , İpar Mehmet Sedat , Kocatepe Demet
Published: December 2020

Genetically modified organisms (GMO), or transgenic products, are products formed by changing the gene sequence of the organism, or by transferring a new gene to the organism and giving it a feature that it does not have. The use of these products in the production of vaccines and drugs, in organ transplants and in the treatment of diseases, ensuring the resistance of plants to pests, long shelf life and increasing food quality are positive; allergic reactions, toxic effects, and damage to ecological diversity are negative effects. In the rese-arch, it was aimed to measure the awareness levels of the personnel about GMOs and their effects on human health. In this context, the universe of the research is composed of all public hospitals in Sinop province, and the sample is composed of personnel working in Sinop Atatürk and Gerze State Hospital. The data of the research were obtained through the questionnaire form created and by the face-to-face interview technique and random sampling method. In this context, data obtained from a total of 312 hospital employees were analyzed with the SPSS 21 package program. As a result of the analysis, it has been determined that the level of social awareness of the participants in GMO foods and their awareness about the presence and harm of GMOs in foods is high. In addition, it was determined that there were differences in terms of gender and marital status of participants according to their perception level of research dimensions.

Authors: Karslı Barış
Published: December 2020

The present study evaluated the effect of extraction techniques (ultrasound-assisted extraction (U) and shaking water bath extrac-tion (WB)), solvents (etha-nol, acetone and distilled water) and concentration (2.5% and 5%) on total phe-nolic content (TPC), anti-bacterial and antioxidant activities of extracts ob-tained from feijoa leaves, peel and pulp. The antibac-terial activity of feijoa ex-tracts were tested in vitro against 6 pathogens bacteria by the disc diffusion method and the antioxidant activity was evaluated by 2,2 diphe-nyl-1-picrylhydrazyl radical assay. The results indicated that leaves and peel extracts exhibited stronger antibac-terial activity than that of pulp. In generally, WB-A5%, WB-W5%, U-A5% and U-W 5% extracted with acetone (A) and water (W) at 5% concentration from feijoa leaves, peel and pulp showed more antibacterial activity against all tested pathogen bacteria. The leaves, peel, and pulp ex-tracts had high antioxidant activity with 85.78-90.82%, 89.86-91.60%, and 81.49-91.31%, respectively. Peel extracts had slightly higher antioxidant activity than leaves and pulp extracts. TPC of leaves, peel, and pulp extracts were in the range of 488.99-554.00, 349.17-517, and 115.64-345.46 mg gallic acid equivalents (GAE)/100 g of extract. The overall findings suggested that different part of feijoa (especially leaves and peel) could be used as a natural antibacterial and an-tioxidant for functional foods.

Authors: Bogutskaya N.G. , Naseka A.M. , Golovanova I.V.
Published: December 2020

The purpose of this paper is giving an extensive overview of the cranial skeleton of Gymnocorymbus ternetzi (Boulenger, 1895) in a form of a formalized scheme that reflect its Bauplan (German for building plan, blueprint; plural: baupläne or bauplaene), a term in biology referring to the common new and original [homologous] properties of the members of a systematic group [taxon]). Each element of the Bauplan can be described by a set of parameters, i.e., size, shape, structure, material composition and position. Though Bauplan is undoubtedly an abstraction, it is a necessary abstraction to be used in phylogenetic analysis with preference to "ingroup" and "outgroup" comparisons.The cranial osteology of black tetra Gymnocorymbus ternetzi (Boulenger, 1895) is described based on the study of larvae, juvenile and adult specimens. Provided are Latin terms and some English equivalents as well remarks on origin, homology and terminology for each cranial bone discussed.

The aim of this study is to investigate the effects of 6-week core strength exercises on TSH (thyroid stimulating hormone), T3 (triiodothyronine) and T4 (thyroxine) levels in men who exercise regularly. A total of 24 healthy volunteers were included in the study with an average age of 20-22 years. Before the study, individuals were randomly divided into two groups as control (n: 12) and core exercise (n: 12) groups. While no application was made to the control group, a program consisting of core exercises suitable for their levels was applied to the core exercise group for 6 weeks, 3 days a week. Blood samples were taken from the forearm veins for analysis of TSH (mlU/L), T3 (pg/ml) and T4 (ng/dl) values from all individuals between 09:00 and 10:00 in the morning before and one day after the exercise application. In the analysis of the data obtained, a statistically significant difference was found in the TSH and T4 values of the exercise group in favor of the post-test (p<0.05). In the statistical analysis of the control and experimental groups, a significant difference was found between the groups in favor of the experimental group (p<0.05). At the end of the study, we can say that core strength exercises applied to men cause changes in thyroid metabolism.

Published: December 2020

Microwave imaging provides an alternative method for breast cancer screening and the diagnosis of cerebrovascular accidents. Before a surgical operation, the performance of microwave imaging systems should be evaluated on anatomically detailed anthropomorphic phantoms. This paper puts forward the advances in the development of breast phantoms based on 3D printing structures filled with liquid solutions that mimic biological tissues in terms of complex permittivity in a wide microwave frequency band. In this paper; four different experimental scenarios were created, and measurements were performed, and although there are many vector network analyzers on the market, the miniVNA used in this study has been shown to have potential in many biomedical applications such as portable computer-based breast cancer detection studies. We especially investigated the reproducibility of a particular mixture and the ability of some mixes to mimic various breast tissues. Afterwards, the images similar to the experimentally created scenarios were obtained by implementing the inverse radon transform to the obtained data.
Accuracy Analysis of Point Velocities Determined by Different Software Packages and GNSS Measurement Processing Methods

Published: December 2020

The paper analyzes the geodynamic network of the City of Zagreb for periodic campaigns carried out from 2006 to 2009 which were processed by different software packages. The first computations and processing results were obtained by using the scientific software Gamit/Globk and indicate the ongoing tectonic activity of the area. In this paper, all calculations were performed by using the scientific software Bernese. Processing strategies and applied error models in the Gamit and Bernese solution are analyzed. The results of the previous analyses show the need to perform GNSS measurements at intervals of up to one year, which is necessary for understanding the mechanism of the structural frame of the wider Zagreb area. The research and analysis performed in this paper indicate certain uncertainties in determining the velocities from periodic one-year GNSS measurements. When periodic GNSS observations are analyzed at time intervals shorter than 2.5 years, annual signals can cause significant errors in determining point velocities. The accuracy of determining velocities between annual time intervals depends on a number of factors: noise level in GNSS measurements, measurement sessions quantity and applied computation strategies. Previously, the time series analysis of observations was a key procedure in the context of geodynamic and geokinematic research and the FODITS algorithm was used for the analysis. A noise analysis on the daily time series of coordinates was performed for the purpose of understanding all influences on geodynamic points. Moreover, a correlation between the time series of observations was determined in order to estimate the final velocity uncertainty error. The purpose of this paper is to demonstrate the applicability of the methods and procedures used to determine the coordinates and velocities of points that can be reliably used for geodynamic and geokinematic analyses and consequently, timely responses to various geophysical phenomena due to earthquakes or other natural phenomena.

Published: December 2020

This paper presents an application of the finite volume method to ideal plastic metal flow in extrusion technology. Governing equations for the mass and momentum balance are used in an integral form. Solution domains in the cases considered are discretized with a Cartesian numerical mesh with computational points placed at the center of each control volume. After discretization of the governing equations, the resulting system of nonlinear algebraic equations is solved by an iterative procedure, using a segregated algorithm approach. Resulting stress fields are obtained from the Levy-Mises equations. The experimental results and numerical calculations are in good agreement.
Londres 2012 año olímpico invita a preguntar: ¿por qué una cátedra olímpica?
Authors: García Forero José Antonio
Published: December 2020

La realización de los Juegos Olímpicos (J.J.O.O.) de Londres 2012 invita a estudiar la historia del olimpismo, a lo que se dedica, someramente, este artículo. En la antigüedad, como en la época moderna, los juegos se celebran cada cuatro años. En la época antigua, se prohibían las guerras para celebrar los juegos, mientras que en la actualidad, se suspendieron los juegos para perpetrar las guerras. Para mantener vivo el espíritu olímpico, el Comité Olímpico Internacional (COI) creó la Academia Olímpica Internacional (AOI) y ésta, a las Academias Olímpicas Nacionales (AON) que, a su vez, crearon las Cátedras de Estudios Olímpicos (CEO), que abarcan en detalle los acontecimientos olímpicos y se detienen en la definición clásica de los J.J.O.O., que corresponde a una convocatoria para competir en deportes aprobados, a nivel internacional. La Universidad de Ciencias Aplicadas y Ambientales U.D.C.A, como líder de las CEO en Colombia, orienta y profundiza en el olimpismo con la filosofía de sus creadores.
Aportes de la mujer en la transformación de los estereotipos socio-culturales del deporte colombiano
Authors: Lucumí Balanta Yanet
Published: December 2020

La participación de la mujer en el deporte colombiano se ha visto enmarcada en diferentes estereotipos socio-culturales que, a lo largo de la historia, se han transformando, incentivando a la mujer para vincularse en los diversos rol del deporte, como en la administración, integrando equipos médico-científicos y como deportista, entre otros. La mujer, al participar en los Juegos Olímpicos, demuestra su potencialidad, su empoderamiento e interés deportivo, contradiciendo los imaginarios colectivos negativos que la señalaban como el sexo débil. Entonces, la pregunta de investigación es: ¿Qué aporta la mujer al deporte colombiano y cómo contribuye a la transformación de los estereotipos socio-culturales, con su participación en los Juegos Olímpicos? La mujer deportista olímpica colombiana aporta con su participación en los Juegos Olímpicos, demostrando con resultados deportivos que es capaz de sobrepasar todos los obstáculos que se le presenten, en la consecución de sus metas deportivas (sueños olímpicos) y, con ello, transforma los estereotipos creados, demostrando que sí está interesada en el deporte, ejecutándolo, a nivel deportivo, obteniendo medallas y ocupando posiciones significativas y en otras actividades de tipo administrativas, sociales y culturales, convirtiéndola en ejemplo a seguir.

Con el objetivo de identificar los métodos de entrenamiento en las capacidades físicas de la fuerza y de resistencia que fueron empleados por los entrenadores con sus deportistas en los Juegos Sudamericanos Medellín 2010, en función de características como: nivel educativo, experiencia deportiva y los procesos desarrollados con los deportistas, se ejecutó un estudio descriptivo-cuantitativo de corte transversal. La muestra intencional estuvo conformada por 93 técnicos (86 hombres y 7 mujeres), provenientes de 13 países, en 28 modalidades deportivas. El estudio, se realizó en la ciudad de Medellín (Colombia), durante marzo de 2010. Se encontró, que el 85,4% de los técnicos tienen formación universitaria y su mayor experiencia como técnicos es a nivel olímpico. Los resultados hallados describen que los métodos más utilizados para el desarrollo de la resistencia fueron el interválico (24,7%), repeticiones (21,3%) y continuo variado (19,7%). Para la fuerza fue el pesista con 65,7%; ocho de cada diez entrenadores son profesionales y presentan buena experiencia a nivel internacional. Por lo tanto, se concluye que no existe una homogenización en la utilización de un método en particular para el desarrollo de la fuerza y de la resistencia.
