Szárnyakkal megkapni és repülve elengedni… avagy biológia tehetségek támogatása a gimnáziumunkban
Authors: Horváthné Hidegh Anikó
Published: September 2019

Discovering, teaching and supporting talents are of high priority in every human community as their future can be greatly influenced by their way of thinking, activities, and works. Teachers have been paying attention to talented children ever since schools exist. We teachers and the schools have to carry the biggest responsibility. In 2008 the Hungarian Parliament voted uniformly for initiating the National Talent Program which was a breakthrough in supporting talents in Hungary. The beginner teachers at that time support their younger colleagues nowadays with their own profession of faith rising to the occasion. Teams of subject teachers and talent groups have been created where they share good practices with each other. The Arany János Primary and Secondary School in Százhalombatta is a complex and multifaceted institution whose talent program was started by the introduction of the Zsolnai method in 1986. Its profile has expanded and changed in the more and more permissive educational environment. In 2001 we started teaching Science (Biology and Chemistry) at an advanced level for the 9th-grade students in our eight-year-long secondary education. In 2014 the National Core Curriculum was modified and obligatory framework curriculum was introduced. Since then only Biology is taught in phasing out system. In addition to the compulsory lessons, we put great emphasis on extra-curricular activities that contribute to talent support. In my article, I would like to present the development of our institution and the proven teaching practices in the field of our biological education.
Nyelvtanulási módszerek és technikák speciális nevelési igényű gyerekek számára
Authors: Klein Ágnes
Published: September 2019

We can read about the problem in several forums and it is one of the most researched neural disorders. In June 2018, the WHO Diagnosis Classification System displayed ICD-11 (The International Statistical Classification of Diseases and Related Health Problems) as a learning disorder that includes reading, writing and counting difficulties. We are not talking about the disorder of intellectual development, but rather as a result of the disruption of perception, movement and sensory integration. This can also occur as a result of genetic but environmentalinduced developmental disorders. In this paper, we will review the difficulties of reading, writing and counting which causes the difficulties of performance and how it occurs in children when learning a foreign language, and how we can help them with the process.

Authors: Martino Ardigo
Published: September 2019

Os processos migratórios e das políticas de proteção à saúde do migrante é na atualidade um problema global a ser enfrentado pelos Estados Nacionais. As crises humanitárias ou sociais, geradas precisam ser observadas a partir da compreensão de uma produção vinculada aos fatos políticos, e processos específicos que não necessariamente tem a ver com os migrantes, mas sim com os países de destino. Portanto, para analisar a saúde dos migrantes e entender o papel da saúde das migrações, seja no contexto Italiano, Europeu ou Brasileiro, é necessário analisar o contexto político e social onde os processos migratórios estão se realizando e os determinantes sociais que esses processos vão gerando.
The Process of European Integration as Historical Phenomena
Authors: Martynov Andrii
Published: September 2019

The purpose of the article is to highlight the structure of the historical process of European integration. Historical phenomenon of the process of European integration is considered as a historiosophical example of unevenness and not the linearity of development. The Great French Revolution set two opposite trends: the development of sovereign national powers while simultaneously spreading universal cosmopolitan ideas. Two world wars weakened Europe’s influence on world history. The idea of “Eurocentrism” turned to the background. The process of European integration has recreated Europe’s influence on the world-historical process. An interdisciplinary methodological approach to the study of European integration considers it an anonymous socio-historical process. The history of Europe demonstrates the various stages of the development of a liberal rational-market project, which is an integral result of the interaction of different social interests. An alternative is the project of ideocratic, focused on the priority of democratic values, human rights, which are the foundation of European modern civilization. The history of European integration of 1957-1990 was a process of overcoming the ideological split of the continent to the East and West in the Cold War. The Maastricht Treaty actually became a watershed in the transition to a postmodern model of European integration. The experience of developing the European integration process has fixed the following main integration-political strategies: federative community; linear expansion and cooperation of the Union of European Peoples; dual strategy: expansion and deepening of integration; d) flexibility and differentiation of “Europe of Nations”; creation of an integration core of Europe and a strategy of many speeds in the process of European integration, (g) intergovernmental cooperation strategy, sectoral integration, (i) the Directorate of the great powers, Europe of flexible geography, or concentric circles. Therefore, from the point of view of the historical process, the crisis of European integration is structural rather than systemic.
The future of skin toxicology testing – Three-dimensional bioprinting meets microfluidics
Authors: Ng Wei Long , Yeong Wai Yee
Published: September 2019

Over the years, the field of toxicology testing has evolved tremendously from the use of animal models to the adaptation of in vitro testing models. In this perspective article, we aim to bridge the gap between the regulatory authorities who performed the testing and approval of new chemicals and the scientists who designed and fabricated these in vitro testing models. An in-depth discussion of existing toxicology testing guidelines for skin tissue models (definition, testing models, principle, and limitations) is first presented to have a good understanding of the stringent requirements that are necessary during the testing process. Next, the ideal requirements of toxicology testing platform (in terms of fabrication, testing, and screening process) are then discussed. We envisioned that the integration of three-dimensional bioprinting within miniaturized microfluidics platform would bring about a paradigm shift in the field of toxicology testing; providing standardization in the fabrication process, accurate, and rapid deposition of test chemicals, real-time monitoring, and high throughput screening for more efficient skin toxicology testing.

Authors: BORANDAĞ Emin
Published: September 2019

In this study, which was carried out using a combination of machine learning and sound processing methods, a speaker recognition system and application were developed using real-time Mel Frequency Cepstral Coefficients (MFCC) features and Markov chain model classifier. A sound sample was taken from each speaker for the training of the system and these sound samples were processed in Fast Fourier Transform and MFCC feature extraction algorithms. The MFCC features were clustered using the k-means clustering algorithm. A Markov chain model was created for each speaker by using the outputs obtained after clustering. By deducting the characteristic features of the voice of the speaker, the person who was talking in the society and how long and at which time intervals they spoke during the conversation was determined in real time with high accuracy.
THE NOTION OF ANIMISM: SOME VIEWS FROM PROPHETIC TRADITION AND WESTERN ANTHROPOLOGIST PERSPECTIVES
Authors: Nasir Khairulnazrin , ISuliaman Ishak , Usman Abur Hamdi
Published: September 2019

Purpose of Study: The prophetic tradition (al-Sunnah) as the second authentic source for Muslims includes guidance that touches all aspects of life, from economics, politics, laws, anthropology, etc. Some Western anthropologists stressed on debating the notion of animism which is a belief that everything exists in the universe has soul, spirit and must be respected. In fact, animism had been revered by all religions, and this theory was introduced by Edward Burnett Tylor (1832-1917) in the 19th century.

Methodology: This article discusses on animism from the perspectives of prophetic traditions and Western Anthropologist. By applying content analysis method, this article found that both parties have some similarities and differences. In lieu of this, Islam concluded that animism or the belief in the power of invisible spirits of people’s ancestors and the spirits of nature to influence the fortunes of humans on earth are blasphemous and deviant. While in view of Anthropologist, animism puts more emphasis on the uniqueness of each individual soul. Animists see themselves on roughly equal footing with other animals, plants, and natural forces, and subsequently, have a moral imperative to treat these agents with respect.

Implications/Applications: The implications for this kind of studies will open to discussions about anthropology through multi background and methods of data collection.

OBRA LITERÁRIA CHUVA BRANCA E COMUNIDADE DO TREME: UMA BREVE REFLEXÃO ACERCA DAS EXPRESSÕES IDIOMÁTICAS UTILIZADAS NESSES ESPAÇOS
Authors: Souza Livia Regina Fernandes , Silva Tabita Fernandes da
Published: September 2019

As expressões idiomáticas se fazem presentes quando termos ou frases assumem um significado diferente de quando são analisados por uma perspectiva isolada, isto é, a interpretação é captada de forma global pela soma das palavras. Devido a estas características, o estudo desses elementos linguísticos se torna cada vez mais difícil, uma vez que a língua possui suas variações e especificidades. Considerando que a obra Chuva Branca (1968) é caracterizada por sua grande abordagem lexical, assim como a comunidade do Treme em Bragança/Pará, este trabalho promoverá uma reflexão acerca dos fatores que contribuem para que algumas expressões idiomáticas estejam presentes nos espaços supracitados, ainda que o tempo e a realidade sejam distintas. É de grande valia ressaltar que este artigo faz parte de uma pesquisa maior que está sendo desenvolvida por meio de uma análise minuciosa e sistematizada dos principais aspectos lexicais da obra e da comunidade, tendo como base a lexicologia e a tradução cultural. Assim, este trabalho destacará pontos relevantes acerca do território amazonense, dando ênfase à cultura e aos hábitos populacionais que influenciaram e influenciam consideravelmente os aspectos linguísticos de um povo, nesse caso, os ribeirinhos.

Violencia de género y discriminación arbitraria en una universidad privada chilena: una exploración inicial
Authors: Sandoval Obando Eduardo , Peña Juan Carlos
Published: September 2019

Los desafíos que enfrentan las Universidades Chilenas en materia de prevención de la violencia de género y discriminación arbitraria develan la necesidad de poner en funcionamiento políticas efectivas que resguarden los derechos fundamentales de sus integrantes. Este trabajo analiza los discursos aportados por los integrantes de una Universidad Privada Chilena, en torno a la violencia de género. Metodológicamente, utiliza un enfoque mixto, procediendo al diseño y envío de una encuesta semiestructurada en línea. El instrumento es respondido por 635 personas, equivalente al 9,35 % del universo muestral. Para la interpretación de los datos, se recurre al análisis estadístico descriptivo y al análisis de contenido, mediante el SPSS Statistics 23.0 y Atlas Ti 6.2. Los resultados evidencian que las mujeres muestran un mayor grado de participación (76,5 %) que los hombres (23,5 %), puesto que ellas son quienes reportan mayormente episodios de violencia psicológica (18 %) y de género (6 %). Asimismo, un 78 % de los participantes declara no conocer a fondo la Política de Denuncia de Casos de Acoso Sexual, Laboral y Discriminación Arbitraria. Además, los participantes manifiestan interés en potenciar las áreas de sensibilización y prevención (33 %) así como el de educación y capacitación (26 %), integrando transversalmente la perspectiva de género en los procesos formativos institucionales. Finalmente, el androcentrismo universitario y la perspectiva de género pendiente emergen como categorías que requieren un análisis profundo y cualitativamente complejo en el ámbito universitario local, lo que favorecería la construcción de una educación no sexista e inclusiva para todos/as.

Determination of Kinetic Order of Reaction for its Duration in the Study of Solvation Factor Effect on Cyclohexene Hydrocarbomethoxylation Catalyzed by Palladium-Phosphine Systems
Authors: Sevostyanova N.T. , Batashev S.A.
Published: September 2019

The purpose of the study was to investigate homogeneous catalytic reaction of cyclohexene hydrocarbomethoxylation leading to the methyl cyclohexanecarboxylate formation. Pd(PPh3)2Cl2 and Pd(OAc)2 which were promoted by free PPh3 and p-toluenesulfonic acid were used as catalytic precursors. In the temperature range 358--393 K, we studied the methanol concentration effect on the value of kinetic order of the reaction with respect to cyclohexene for the duration of the reaction. Findings of research show that the kinetic order increased from 1 to 10 with temperature increase and methanol concentration rise. We compared the kinetic order values for the duration of the reaction and the concentration order with respect to cyclohexene, which is equal to 1, set for the initial rate region. Based on this comparison, it was suggested that the formation of inactive palladium complexes is progressed by the action of excess methanol at elevated temperatures. We found that the regularities of methanol effect on the cyclohexene hydrocarbomethoxylation rate for the duration of the reaction were agreed with the regularities discovered for the initial rate region. With consideration of the data about enthalpy change in the ligand exchange reactions between the palladium complexes with participation of CH3OH, СО and PPh3, we draw the conclusion about the dominant contribution of specific solvation to the catalyst deactivation in the conditions of high methanol concentrations
A Theoretical Study of Light Soliton Produced by Semiconductor Quantum Dot Waveguides and Propagation in Optical Fibers
Authors: Swami O.P. , Kumar V. , Suthar B. , Nagar A.K.
Published: September 2019

In this paper, the propagation of light soliton is studied in nonlinear optical fiber. We propose the external excitation of SQD waveguides through an optical source that allows the generation of solitary waves that are propagated through a non-linear optical fiber. The soliton formation is studied theoretically from the non-linear interaction between the external optical excitation and SQDs, considering SQDs as a quantum system of three energy levels. In this study, the Fourier Split-Step (FSS) method is used to solve numerically continuous nonlinear Schrodinger equation (NLSE) to evolution of the soliton pulse emitted by the SQDs inside an optical fiber with real physical parameters. The effect of SQDs density and electric field on the pulse width is also studied. Phase plane portraits are drawn for the stability of soliton in fiber and SQDs using software Matcont.

Published: September 2019

We demonstrate that the dynamics of tax competitiveness in the EU has gained a new higher level. The shift in the tax competition can be noted after new countries have joined the EU. Both positive and negative effects of tax competitiveness are discussed in the paper and the question of trade-off between the strong tax competitiveness of a country and magnitude of its tax revenue is raised. Evaluation of chosen countries using multiple criteria decision aid methods (MCDA) shed more light on the opposition of two groups of countries, the old and new members of the EU, provided more details on the both the present state and dynamics of tax competitiveness in the. The evaluation methodology can be successfully used for monitoring the current state of tax competitiveness of each member country. Prominence of the multiple criteria evaluation TOPSIS method of MCDA evaluation is described.

Keywords: Competitiveness of countries, tax system, tax competition, tax revenues, multiple criteria evaluation, TOPSIS.
The Good Egg by J., J., and P. Oswald
Authors: Gordon Tara
Published: September 2019

John, Jory and Pete Oswald. The Good Egg. HarperCollins Children’s Books, 2019.

This imaginative picture book by bestselling creators Jory John and Pete Oswald uses beautiful illustrations and humour to tackle social and emotional skills. The Good Egg is the counterpart to the duo’s book The Bad Seed.

As the title suggests, the main character of this book is a good egg, “A verrrrrry good egg.”

The beginning of the book shows how the good egg stands apart from the rest of the rowdy dozen in his carton by trying to do good deeds—he’s rescuing a cat when we first meet him.

But as the story progresses, we see that the good egg is trying so hard to be good, while everyone around him is rotten, that he reaches a breaking point. The good egg literally begins to crack from all of the self-imposed pressure. Deciding that it is in his best interest to leave the carton, the good egg embarks on a journey of self-care, and self-reflection.

On his journey, the good egg finds peace by taking walks, reading, writing in his journal, and just breathing. Eventually, the good egg starts to feel like himself again. At the same time, he realizes that he is lonely without his friends. He learns that even though the other eggs aren’t perfect, he doesn’t have to be either. The good egg decides that it is much better to be with those you love than to be alone, so he returns to his carton.

The detailed and expressive illustrations by Oswald bring the characters in The Good Egg to life, making them relatable to kids. The story flows nicely with just the right amount of words, making it a good read-aloud, and useful for class and family discussions on topics like perfectionism, self-care, and accepting yourself and others as they are. It is one of those picture books that gives kids an opportunity to put themselves in someone else’s shoes and to empathize. Overall, The Good Egg reminds us of the importance of balance and self-care, and accepting those we love, even if they are a bit rotten sometimes.

Highly recommended: 4 stars out of 4Reviewer: Tara GordonTara Gordon is a University of Alberta SLIS student with a lifelong passion for children’s books. Outside of school, Tara enjoys spending time with her husband and two children.
Failure Analysis of fractured Fixing Bolts of a Mobile Elevating Work Platform using Finite Element Methods
Authors: Choi DongHoon , Kim Jae-Hoon
Published: September 2019

Mobile elevating work platforms (MEWPs) consist of a work platform, extending structure, and chassis, and are used to move persons to working positions. MEWPs are useful but are composed of pieces of equipment, and accidents do occur owing to equipment defects. Among these defects, accidents caused by the fracture of bolts fixed to the extension structure and swing system are increasing. This paper presents a failure analysis of the fixing bolts of MEWP. Standard procedure for failure analysis was employed in this investigation. Visual inspection, chemical analysis, tensile strength measurement, and finite element analysis (FEA) were used to analyze the failure of the fixing bolts. Using this failure analysis approach, we found the root cause of failure and proposed a means for solving this type of failure in the future. First, the chemical composition of the fixing bolt is obtained by a spectroscopy chemical analysis method, which determined that the chemical composition matched the required standard. The tensile test showed that the tensile and yield strengths were within the required capacity. The stress analysis was carried out at five different boom angles, and it was determined that the fixing bolt of MEWP can withstand the loads at all the boom angles. The outcomes of the fatigue analysis revealed that the fixing bolt fails before reaching the design requirements. The results of the fatigue analysis showed primarily that the failure of the fixing bolt was due to fatigue. A visual inspection of the fractured section of the fixing bolt also confirmed the fatigue failure. We propose a method to prevent failure of the fixing bolt of the MEWP from four different standpoints: the manufacturer, safety certification authority, safety inspection agency, and owner.
Some Questions and Answers About the Role of Hox Temporal Collinearity in Vertebrate Axial Patterning
Authors: Durston A.J.Durston
Published: September 2019

The vertebrate anterior-posterior (A-P = craniocaudal) axis is evidently made by a timing mechanism. Evidence has accumulated that tentatively identifies the A-P timer as being or involving Hox temporal collinearity. Here, I focus on the two current competing models based on this premise. Common features and points of dissent are examined and a common model is distilled from what remains. This is an attempt to make sense of the literature.

The research sets to examine the influence of Problem Based Learning (PBL), critical thinking ability, and collaboration toward learning outcome of Christian Junior High School (SMPK) Stelamaris Biudukfoho. Quasi experiment using non-equivalent control group design is employed in this research. The first and the second experiment group are selected based on assignment random sampling. There are 60 subjects at the eighth grade of Junior High School in the academic year of 2018/2019. The researchers apply test to measure critical thinking ability and learning outcome, whereas questionnaire is employed to measure collaboration of the students. The data analysis is three-way analysis of variance. The results reveal that there is significant differentiation of learning outcome between a group using PBL and a group using conventional method, between the students with high and low critical thinking ability, between the students with high and low collaboration. In addition, there is significant interaction of learning model, critical thinking ability, and collaboration toward students’ learning outcome. It means that students’ learning outcome depends on the learning model, critical thinking ability, and collaboration of the students
Modeling of Matrix/Fracture Transfer with Nonuniform-Block Distributions in Low-Permeability Fractured Reservoirs
Authors: Ding Didier–Yu
Published: September 2019

Unconventional shale–gas and tight oil reservoirs are commonly naturally fractured, and developing these kinds of reservoirs requires stimulation by means of hydraulic fracturing to create conductive fluid–flow paths through open–fracture networks for practical exploitation. The presence of the multiscale–fracture network, including hydraulic fractures, stimulated and nonstimulated natural fractures, and microfractures, increases the complexity of the reservoir simulation. The matrix–block sizes are not uniform and can vary in a very wide range, from several tens of centimeters to meters. In such a reservoir, the matrix provides most of the pore volume for storage but makes only a small contribution to the global flow; the fracture supplies the flow, but with negligible contributions to reservoir porosity. The hydrocarbon is mainly produced from matrix/fracture interaction. So, it is essential to accurately model the matrix/fracture transfers with a reservoir simulator.

For the fluid–flow simulation in shale–gas and tight oil reservoirs, dual–porosity models are widely used. In a commonly used dual–porosity–reservoir simulator, fractures are homogenized from a discrete–fracture network, and a shape factor based on the homogenized–matrix–block size is applied to model the matrix/fracture transfer. Even for the embedded discrete–fracture model (EDFM), the matrix/fracture interaction is also commonly modeled using the dual–porosity concept with a constant shape factor (or matrix/fracture transmissibility). However, in real cases, the discrete–fracture networks are very complex and nonuniformly distributed. It is difficult to determine an equivalent shape factor to compute matrix/fracture transfer in a multiple–block system. So, a dual–porosity approach might not be accurate for the simulation of shale-gas and tight oil reservoirs because of the presence of complex multiscale–fracture networks.

In this paper, we study the multiple–interacting–continua (MINC) method for flow modeling in fractured reservoirs. MINC is commonly considered as an improvement of the dual–porosity model. However, a standard MINC approach, using transmissibilities derived from the MINC proximity function, cannot always correctly handle the matrix/fracture transfers when the matrix–block sizes are not uniformly distributed. To overcome this insufficiency, some new approaches for the MINC subdivision and the transmissibility computations are presented in this paper. Several examples are presented to show that using the new approaches significantly improves the dual–porosity model and the standard MINC method for nonuniform–block–size distributions.

It has been demonstrated that the Gaussian-mixture-model (GMM) fitting method can construct a GMM that more accurately approximates the posterior probability density function (PDF) by conditioning reservoir models to production data. However, the number of degrees of freedom (DOFs) for all unknown GMM parameters might become huge for large-scale history-matching problems. A new formulation of GMM fitting with a reduced number of DOFs is proposed in this paper to save memory use and reduce computational cost. The performance of the new method is benchmarked against other methods using test problems with different numbers of uncertain parameters. The new method performs more efficiently than the full-rank GMM fitting formulation, reducing the memory use and computational cost by a factor of 5 to 10. Although it is less efficient than the simple GMM approximation dependent on local linearization (L-GMM), it achieves much higher accuracy, reducing the error by a factor of 20 to 600. Finally, the new method together with the parallelized acceptance/rejection (A/R) algorithm is applied to a synthetic history-matching problem for demonstration.

Water is considered the ‘oil of space’ with applications ranging from fuel production to colony consumption. Recent findings suggested the presence of water-ice in the Permanently shadowed craters on Lunar poles. This water present on the Moon and other planetary bodies can significantly bring down the cost of space exploration, fueling the colonization of the solar system. With low-resolution orbital data available, the next step is to drill and analyze samples from the Moon.

An extensive review of drilling systems designed by NASA was conducted focusing on the effect of different planetary environments on the drill design. Inspired by this and the drilling systems developed in the petroleum industry, an auger based rotary drilling rig was designed and fabricated with an extensive high-frequency data acquisition system, measuring all essential drilling parameters. Several analog rocks were cast with regolith simulant grout to replicate different subsurface geotechnical properties in the Lunar polar craters. The drill was tested on samples with different geotechnical properties to account for the varying properties expected in the Lunar poles.

Application of the drilling engineering concepts has resulted in the development of a robust drilling system capable of replicating drilling process for different planetary environments like the Moon and Mars. Using the data acquisition system on the rig, an advanced machine learning algorithm capable of processing and analyzing the real-time high-frequency drilling data to estimate a sample's geotechnical properties and water content was created. The evolving algorithm was developed based on initial drilling tests on homogenous and heterogeneous analogs. It was tested on samples with varying heterogeneity to estimate the geotechnical properties and the water content accurately. With some modifications, this algorithm can be applied in the Lunar and Martian missions to estimate the geotechnical properties in real-time, without the need to analyze the subsurface samples on the surface. This can result in a cost-effective exploration of water-ice resources on the Moon and Mars, kickstarting the space resources industry and the human colonization on those planetary bodies. The expertise of the drilling engineers in designing and executing wells in extreme terrestrial environments can help create significantly effective drilling systems for extraterrestrial environments.

This work details the design considerations to drill on the Moon and other planetary bodies focusing specifically on the application of drilling data to evaluate geotechnical properties and water content at Lunar polar conditions. The techniques developed here might pay a vital role in understanding the extent and composition of water-ice on the Moon, leading to efficient colonization of the solar system.
