Gas Turbine Performance Enhancement for Naval Ship Propulsion using Wave Rotors
Authors: Fatsis A , Al Balushi A S N
Published: December 2019

The propulsion demands of high speed naval vessels often rely on gas turbines fitted in small engine rooms, producing significant amounts of power achieving thus high performance requirements. Gas turbines can be used either to provide purely mechanical propulsion, or alternatively to generate electricity, which is subsequently used by electric drives to propel the ship. However, the thermal efficiencies of gas turbines are lower than those of Diesel engines of similar power, in addition to the fact that all gas turbines are less efficient as the ambient temperature rises, particularly for aero-derivative engines. In the context of improving the performance of existing marine gas turbines with minimum modifications to their baseline configuration, this article is proposing engine’s performance enhancement by integrating a pressure wave supercharger (or wave rotor), while keeping the compressor, combustion chamber and turbine entry temperature of the baseline engine unchanged. Thermodynamic cycle analysis for two-shaft gas turbine engines configurations with and without heat exchanger to recuperate the waste heat from the exhaust gases, typical for marine propulsion is performed for the baseline engines, as well as for the topped with four-port wave rotor engines, at design point conditions and their performances are compared accordingly. Important benefits are obtained for four-port wave rotor-topped engines in comparison to the self-standing baseline engines for the whole range of engine’s operation. It is found that the higher the turbine inlet temperature is, the more the benefit gain of the wave rotor topped engine is attained in terms of efficiency and specific power. It is also concluded that the integration of wave rotor particularly favours engines operating at low compressor pressure ratios and high turbine inlet temperatures. The effect of variation of the most important parameters on performance of the topped engine is investigated. It is concluded that wave rotor topping of marine gas turbines can lead to fuel savings and power increase.

Este artículo se propone narrar una parte de nuestra experiencia vivida a lo largo de varios semestres tratando de enseñar ideas fundamentales de la teoría del cálculo. Nos proponemos explicar cómo ha ido cambiando nuestra mentalidad didáctica y matemática al ser testigos de las dificultades conceptuales de los estudiantes –y vivirlas con ellos– cuando son confrontados con situaciones que generan una tensión entre sus intuiciones y el rigor aritmético propio del análisis. Las atmósferas vividas en el salón de clases, las tensiones entre los intentos de enseñar y los profundos obstáculos para el aprendizaje nos indican la existencia de una fisura epistémica al intentar transitar de una manera de entender sensorio-motriz a otra de rigor aritmético.

Published: December 2019

A soldagem a laser é amplamente utilizada na indústria automotiva, pois apresenta qualidade no acabamento, aporte de energia e redução da zona afetada pelo calor. No entanto, a limitação quanto à espessura do cordão de solda, instabilidade no foco do laser e a dificuldade em guiá-lo para a região de soldagem exigem sistemas robotizados de alta precisão para a aplicação de maneira adequada. O processo na unidade fabril em questão é totalmente robotizado, porém, apresentou instabilidade durante a soldagem, resultando em falhas no cordão e desgaste prematuro dos bicos de soldagem. Este trabalho, por meio da metodologia DMAIC, estabeleceu a correlação entre as falhas no cordão de solda, troca excessiva dos bicos e cast do arame de soldagem. Foi determinada a causa raiz do problema e propôs-se soluções viáveis, as quais foram implementadas. A partir dessas ações na empresa automotiva, foi possível reduzir o consumo de bicos em 60% durante o processo de soldagem, permitindo manter o índice de falhas abaixo de 0,6 a cada mil unidades inspecionadas.Palavras-chave: DMAIC. Soldagem a Laser. Indústria Automotiva.ABSTRACTLaser welding is widely used in the automotive industry, because it offers quality in finishing, energy supply and reduction of the heat affected zone. However, limiting the thickness of the weld bead, instability in the focus of the laser and the difficulty in guiding it to the welding region, requires high-precision robotic systems for proper application. The process in the industry in question is totally robotized, but it showed instability during welding, resulting in cord failure and premature wear of the welding nozzles. This work, through the DMAIC methodology, established the correlation between weld bead failures, excessive nozzle exchange and cast welding wire. The root cause of the problem was determined and viable solutions were proposed and implemented. From these actions in the automotive industry it was possible to reduce the nozzle consumption by 60% during the welding process, allowing to keep the failure rate below 0.6 per thousand inspected units.Keywords: DMAIC.

Published: December 2019

A camada de cobre alcalino confere proteção ao zamac nos processos químicos posteriores, enquanto que a camada de cobre ácido confere nivelamento bem como a camada de níquel que confere brilho e proteção à peça. Neste sentido, esse trabalho tem por objetivo avaliar a influência dos parâmetros do processo de eletrodeposição das camadas de cobre e níquel na resistência à corrosão do zamac 5. Para tanto, camadas de cobre foram eletrodepositadas em amostras de zamac, com aplicação de 2V por 30 minutos e de 1V por 5 minutos + 2V por 40 minutos. Em cima desses depósitos, camadas de cobre ácido foram eletrodepositadas com aplicação de 2V por 30 minutos. Por último, sobre as camadas de cobre foram eletrodepositadas camadas de níquel com aplicação de 4V por 8 minutos e 4V por 20 minutos. O zamac sem e com revestimentos foi avaliado por Microscopia Eletrônica de Varredura (MEV), e quanto ao desempenho corrosivo por testes eletroquímicos (polarização). Os resultados mostraram que a diferença de tensão aplicada na eletrodeposição (1V e 2V) e o aumento de tempo (5min. e 40 min.), possibilitaram a obtenção de uma camada de cobre alcalino mais homogênea e uniforme e consequentemente mais resistente à corrosão do zamac em relação à camada de cobre alcalino com voltagem e tempo constante (2V por 30 min.). Palavras-chave: Corrosão. Eletrodeposição. Zamac. Cobre. Cristais. Porosidade.ABSTRACTThe alkaline copper layer provides zamac protection for subsequent chemical processes, while the acidic copper layer imparts leveling and the nickel layer imparts luster and protection to the part. In this sense, this work has the objective of evaluating the influence of the parameters of the electrodeposition process of copper and nickel layers on the resistance to the corrosion of zamac 5. For this, copper layers were electrodeposited in zamac samples, applying 2V by 30 minutes and 1V for 5 minutes + 2V for 40 minutes. On top of these deposits, layers of acid copper were electrodeposited with 2V application for 30 minutes. Finally, on the copper layers were electrodeposited layers of nickel with application of 4V for 8 minutes and 4V for 20 minutes. Zamac without and with coatings was evaluated by Scanning Electron Microscopy (SEM), and for the corrosive performance by electrochemical tests (polarization). The results showed that the voltage difference applied in the electrodeposition (1V and 2V) and the increase of time (5min and 40min) allowed to obtain a more homogeneous and uniform alkaline copper layer and consequently more corrosion resistant zamac in relation to the alkaline copper layer with voltage and constant time (2V for 30 min.).Keywords: Corrosion.

Design Pattern Evaluation on A RESTful API Wrapper: A Case Study of Software Integration with An Internet Payment Gateway using Model-Driven Architecture
Authors: Manik Lindung Parningotan
Published: December 2019

A proper use of design patterns has proven to be very useful in the development of robust applications over time. In this paper, the design patterns are introduced in the early stage of the software development where model-driven architecture is used as the engineering approach. A RESTful internet payment gateway API (Application Programming Interface) wrapper is selected as the case study. At the beginning, Platform Independent Model (PIM) is created as the domain model. After that, the PIM is transformed into the Platform Specific Model (PSM). Before converting the PSM into the source code, three design patterns such as builder, observer, and factory pattern are added into the model. To evaluate the impacts of implementation, static analysis is used to examine the generated code before and after adding the design patterns. The result shows that the design decision increases cohesion, complexity, coupling, inheritance, and size metrics of the source codes.

Published: December 2019

A Estratégia Saúde da Família (ESF) possibilita, por meio da articulação de olhares e saberes dos diferentes profissionais da equipe multiprofissional, o desenvolvimento de ações que ultrapassam a racionalidade da assistência curativa, centradas na resolução imediata de problemas de saúde individuais. Este estudo teve como objetivo geral descrever o trabalho da equipe multiprofissional da ESF, relatando as potencialidades, os principais desafios e dificuldades do trabalho multiprofissional na Atenção Primária. A metodologia se deu por meio de uma revisão integrativa de literatura, que se baseia em cinco etapas, indo desde a seleção de artigos até a síntese do conhecimento dos artigos analisados. Percebe-se que os processos de trabalho entre os profissionais da equipe multiprofissional, passaram por grandes mudanças desde o início da estratégia, a qual ultrapassa a racionalidade da assistência curativa e hoje tem como foco os modelos de assistência à saúde, através do desenvolvimento da tecnologia leve. Quanto aos desafios, conclui-se que a multiprofissionalidade por si não é condição suficiente para garantir a recomposição dos trabalhos. Observou-se a falta de infraestrutura, inadequação e insuficiência de recursos necessários para a realização do trabalho, hierarquização no trabalho em equipe, deficiência quanto ao apoio institucional e valorização profissional. Assim, torna-se fundamental reconhecer a importância das relações interpessoais e da comunicação para reestruturação das práticas assistenciais de trabalho em saúde.

Published: December 2019

O trabalho é componente fundamental na construção da identidade do sujeito. Isso se confirma e solidifica na docência, ou seja, nas relações diárias do professor com a sociedade, a instituição e os alunos. O docente é um trabalhador essencial para a sociedade, na medida em que está inserido no processo ensino-aprendizagem e é responsável pela criação de vínculos sociais, confirmando o seu papel de destaque na sociedade. O presente artigo propõe-se a identificar as doenças/disfunções ocupacionais que acometem professores e que estejam relacionadas às condições de trabalho e à dinâmica das práticas docentes, mostrando uma relação de causa e consequência. Realizou-se uma revisão bibliográfica nas bases de dados Scielo, Lilacs e Pubmed, utilizando os descritores: doenças ocupacionais, docentes, saúde do trabalhador, condições de trabalho e estresse ocupacional, em concordância com os Descritores em Ciências da Saúde (DeCS) da BVS, sendo possível conhecer como o trabalho docente expõe este profissional ao adoecimento, principalmente aos distúrbios osteomusculares, da voz e psíquicos. Observou-se que a classe docente tem sido submetida às novas exigências decorrentes do ritmo acelerado na produção tecnológica, e isso tem contribuído para alterações nas relações que se desenvolvem no ambiente de trabalho, e, com isto, supõe-se que professores tem desenvolvido problemas de saúde, muitas vezes se afastando das atividades laborais, o que acarreta elevado custo econômico às instituições e à seguridade social. Conclui-se, dessa forma, que há fatores relacionados ao trabalho docente que podem ser causas de adoecimento, ainda mais quando associado a estilo de vida inapropriado.

Authors: Subramaniam S. Muruga , Ishii Kazuhiko , Sheng Chen Jui , Nakatomi Hirofumi , Takai Keisuke , Saito Nobuhito
Published: December 2019

Background:

Spinal arteriovenous fistulas (AVFs) are vascular lesions that often pose significant surgical challenges. This is particularly true for those located close to the anterior spinal artery. Here, we analyzed the surgical options for treating an anterior perimedullary AVF (pAVFs).

Case Description:

A 66-year-old male with the right lower extremity weakness was diagnosed with a spinal dural AVF at the L1 level. It was initially treated with open surgery followed by CyberKnife radiosurgery at another institution. Five years later, he presented with a persistent pAVF fistula now involving the T11 level; the major feeder originated on the left at the T7–T8 level (e.g., involving a left-sided “duplicated” anterior spinal artery). Utilizing a three-dimensional (3D) computer tomography (CT) guided approach; he underwent a left-sided posterolateral T10–T12 laminectomy, sufficient to allow for 30–40° of anterior spinal cord rotation. This was performed under neurophysiological monitoring without any significant changes. Surgery included indocyanine green video angiography, temporary feeder clipping, and complete occlusion of the AVF, followed by complete clipping/resection as confirmed on postoperative magnetic resonance imaging.

Conclusion:

Utilizing a 3D CT image, a ventral pulmonary arteriovenous malformation was excised utilizing a left-sided posterolateral approach allowing for 30–40° of cord rotation.
Egy új törvényi tényállás szükségességéről
Authors: Szabó Zsolt Tibor
Published: December 2019

A Büntető Törvénykönyvről szóló 2012. évi C. törvény (a továbbiakban: Btk.) 420. § (1) bekezdésében foglalt törvényi tényállás az egyedüli az egész büntető kódexben, amelynek diszpozíciójában tényállási elemként szerepel a közbeszerzési eljárás. Ennek ellenére, a közbeszerzési eljáráshoz további, olyan büntetni rendelt tényállások is társíthatók, amelyek szükségszerűen megvalósulnak, befejezetté válnak stádiumtani szempontból, ha az állami közpénzek pályáztatás során történő kiosztásakor megjelenik a felek közötti bűnös kapcsolat.

A teljesség igénye nélküli vizsgált, eljárásbeli magatartásokból kitűnik, hogy egy nem tisztességes közbeszerzési eljárás alapja valamely korrupciós bűncselekmény elkövetése; majd a lezárt közbeszerzési eljárás után, a ne bis in idem elvének sérelme nélkül válik tényállásszerűvé a versenyt korlátozó megállapodás bűntette, azaz a Btk. 420. § (1) bekezdésében rögzített tényállás nem azonos a közbeszerzési korrupció fogalmával. Ennek igazolására felvázolom, hogy mit értek közbeszerzési korrupció alatt.

Tanulmányomban arra törekszem elsődlegesen, hogy alátámasszam, a hivatkozott deliktum nem képes betölteni azt a jogalkotói célt, hogy a közbeszerzési korrupciót visszaszorítsa; másodlagosan egy új törvényi tényállás szükségességének okaira is kitérek.
A társadalmi közfelelősség kérdései Nagy-Britanniában és Magyarországon

Published: December 2019

A társadalmi felelősségvállalás jelentős fejlődésen ment át az elmúlt években. A koncepció szépen lassan az élet minden területére, személyes életünkbe, a gazdasági szférába és végül a közszférába is sikeresen utat tört magának. Jelenleg számos állam küzd bizonyítottan problémákkal a közszférában, és a társadalmi közfelelősség egyike azoknak az irányvonalaknak, amelyek mentén egy átfogó közigazgatási reformot el lehetne indítani. A tanulmányban a társadalmi közfelelősség brit és magyar megoldásait vizsgáljuk meg. Az Egyesült Királyság példája habár előttünk áll, nem biztos, hogy az alapvető jogrendszerbeli és gondolkodásmódbeli különbségek miatt a többi európai ország számára ugyanaz lesz a megfelelő út a PSR megvalósítása felé, ami az angolszász királyságban működőképes.
Religious Education as Small ‘i’ Indoctrination: How European Countries Struggle with a Secular Approach to Religion in Schools
Authors: Alberts Wanda
Published: December 2019

This article critically reviews the European religious education landscape and argues that a religious notion of religion prevails in most models, not only in confessional RE but also in integrative models and even in so-called alternative subjects that are compulsory for pupils who do not take part in confessional RE. Thus, schools in Europe provide hardly any chance for pupils to acquire a secular perspective on religion and religious diversity, based on a non-theological study of religion. Furthermore, the explicitly or implicitly religious character, particularly of integrative approaches or obligatory alternative subjects to confessional RE, is frequently hidden or played down. Building on analyses of separative (Germany) and integrative (Norway, England) models of RE, the article argues that carefully distinguishing between religious and secular approaches to religion in school is a serious human right’s issue, not least because only secular approaches may be compulsory. The predominant religious framing of religion – that is always linked to confirming the exceptional position of Christianity among the religions in RE – in combination with an actual lack of secular alternatives creates a climate of what may be called ‘small ‘i’ indoctrination’, i.e., an unquestioned discursive hegemony of a particular (Christian) notion of religion as a frame of reference for almost all education about religion, which is, furthermore, often represented as if it constituted not a particular religious view of religion, but a kind of universal perspective on religion. This results in highly problematic conceptualisations, both of religion in general and individual religions – most visibly in stereotyping ‘other’ religions, that are not complemented with an unbiased secular perspective. Thus, the subject matter religion is widely exempted from the secular approach to education in European schools, while a particular religious perspective on religion is promoted, even in models that are designed for all pupils of a religiously heterogeneous class.
A regulação estatal para incentivar o primeiro emprego dos jovens no Brasil: elementos para o desenvolvimento econômico
Authors: Maciel Lucas Pires , Rossignoli Marisa
Published: December 2019

A inserção do jovem no mercado de trabalho é temática relevante, tanto no aspecto de desenvolvimento econômico e social, como na gestão empresarial. O presente trabalho objetivou discutir formas para incentivar as empresas à contratação de jovens de 15 a 24 anos de idade para o seu primeiro emprego formal. A metodologia utilizada foi a revisão bibliográfica com uso do método dedutivo e análise de dados primários obtidos na Pesquisa Nacional por Amostra de Domicílios - PNAD. Como resultado verifica-se a necessidade do estimulo por meio de políticas públicas uma vez que o desemprego entre os mais jovens tem sido alto, reflexo muitas vezes da falta de experiência em função da dificuldade do primeiro emprego, o uso de políticas públicas tende a reduzir o desemprego que na faixa de 18 a 24 anos encontrava-se em 25,8% no terceiro trimestre de 2018 e criar condições para que as empresas contratem. Conclui-se assim sobre a necessidade de política específica.

Contribuição social sobre o lucro: diferenciação ou sobrecarga?
Authors: Afonso José Roberto Rodrigues , Szelbracikowski Daniel Corrêa , Correia Neto Celso
Published: December 2019

A contribuição para seguridade social exigida dos empregadores sobre seus lucros foi prevista pela Constituição de 1988, além do imposto de renda das pessoas jurídicas. Desde que iniciada a sua cobrança, foi exigida de instituições financeiras alíquota superior a dos demais contribuintes. A diferenciação por atividade foi contemplada por emenda constitucional mas surgem dúvidas sobre que justifica tal tratamento desigual. A ampliação das atividades sujeitas a maior alíquota e como esta foi seguida e expressivamente majorada se questiona a fronteira entre diferenciação e sobrecarga.
Situação jurídica: a supressão da autoridade parental por ordem judicial e o posterior exercício (i)legal de direitos e deveres perante os filhos
Authors: Zuin Mattos do Amaral Ana Cláudia Corrêa , Ciola de Castro Paulo Roberto , Vasconcellos Nayara Rangel
Published: December 2019

Explicita-se a evolução da noção clássica de relação jurídica, associada aos sujeitos de direito, à situação jurídica, referente aos centros ou núcleos de direitos e interesses. Empreende-se um exame casuístico, no qual o restabelecimento do poder parental é pleiteado pela genitora, mesmo não havendo amparo no direito objetivo nesse sentido. Referida apuração causal ocorre sob a perspectiva de disposições normativas afetas ao direito das famílias, expondo-se pessoas como núcleos de interesses, em face de decisões judiciais. A partir do método científico dedutivo, reunindo-se conceitos doutrinários, demonstra-se que o reconhecimento da existência do núcleo de interesses permite o restabelecimento da autoridade parental, materializando-se a situação fática existente, mesmo em detrimento de ordem judicial anterior que extinguiu o poder parental.
Do paradigma da complexidade à produção normativa processual democrática
Authors: Moller Gabriela Samrsla , Dos Santos Paulo Junior Trindade , Gracioli André Antônio
Published: December 2019

Do paradigma da complexidade à produção normativa processual democrática inicia pelo estudo do paradigma da complexidade, no qual impera uma racionalidade reflexiva-aberta que pressupõe a transdisciplinariedade, ainda não assimilada pelo Direito, além do estudo da possibilidade de o Judiciário se tornar a porta de entrada para a assunção de tal paradigma pela ciência jurídica. O problema pode ser encontrado no paradigma da complexidade oriundo de um mundo global cada vez mais plural, no qual o Direito, ainda preso no paradigma mecanicista, não se abre à transdisciplinariedade. A hipótese é a possibilidade de internalização de tal paradigma pelo renovado papel do Judiciário, em que o processo é legitimado democraticamente e assume a função de formulação e concretização de direitos, sejam eles promessas constitucionais reprimidas ou novas demandas. Os objetivos são a preocupação em abordar o paradigma da complexidade e sua racionalidade aberta-reflexiva e, em seguida, apresentar o Judiciário e o Processo como elementos para adequar o Direito a tal paradigma. A metodologia utilizada é a bibliográfica. Com isso, busca-se analisar a relação entre a nova racionalidade e Processo, reflexão que se faz necessária ao Direito, dado que o antigo paradigma da ciência, fundado na unicidade e especialização de disciplinas e que culmina na Lei e no Código, vem a ser renovado pelo paradigma da complexidade.

This research is motivated by the importance of the ability to understand students' mathematical concepts. Alternative learning to improve these abilities is a learning model of contextual teaching and learning. The purpose of this study was to determine the effect of contextual teaching and learning on the ability to understand mathematical concepts in terms of student motivation. The research design used in this study is Quasi Experimental Design with factorial 2 × 3. Sampling using Cluster Random Sampling technique. The population in this study were all seventh grade students in Bawang 1 State Middle School. The data in this study were obtained from the results of the posttest ability to understand mathematical concepts and student motivation questionnaires. Data processing is done by using the same two-way cell anava calculation followed by the Scheffe 'test and regression test to know the magnitude of the effect. Conclusions from the results of processing the data are 1) The ability to understand mathematical concepts in set material using the contextual teaching and learning learning model provides the ability to understand mathematical concepts that are the same as students with conventional learning models. 2) Students with high motivation have the ability to understand mathematical concepts better than students with low motivation, and students with moderate motivation have the ability to understand the same mathematical concepts as students who have low motivation. 3) There is no difference in students' ability to understand concepts between students who are given a contextual teaching and learning model and conventional on the level of student motivation. 4) Motivation of learning affects the ability to understand students' mathematical concepts in students given the model of contextual teaching and learning. Learning motivation can be used as an alternative to the affective aspect in measuring the ability to understand students' mathematical concepts, especially in set material because motivation affects the ability to understand mathematical concepts of class VII students.

In this study, it is aimed to examine this research from a wide perspective and to emphasize the importance of more specific studies on the subject.

In this research, national and international studies on self-harm behavior were compiled.

Self-injurious behavior is frequently encountered as an advanced behavioral problem. (Şipal, 2010) Self-injurious behavior is that a person can harm one's own tissues in such a way as to cause severe acts without the will to die consciously. Self-injurious behavior is associated with many psychiatric disorders. In addition, deliberate self-harm behavior should be separated from suicide attempts. Self-injurious behavior usually begins in adolescence. “In the community sample studies, it was found that self-injurious behavior was seen in 1/3 and 1/2 of adolescents (Lloyd-Richardson et al. 2007, Yates et al. 2008). self-injurious behavior typically begins in adolescence and often occurs impulsively; adolescents and young adulthood (Claassen et al. 2006) (Bildik, Somer, Basay, Basay, &Ozbaran, 2012). According to the results of the study, identity confusion and low self-esteem symptoms were found to be significantly more frequent in adolescents with self-injurious behavior (Akdemir, Zeki, Unal, Kara, & Cetin, 2013). It is observed that traumas experienced in the past are related to deliberate self-harm behavior. There are many reasons for self-harm behavior. One of them is abuse. If the trauma experienced is remembered, self-harm behavior arises in order to replace the high level of anxiety with physical pain. Miller and Favazza investigated the reasons for self-mutilation and listed the factors that caused self-mutilation as follows: To have a sense of relaxation; Suppressing emotional pain; Moving away from the feeling of emptiness to show their experiences.(Aksoy, Ögel, 2003). However, in individuals who frequently repeat the act of self-harm, feelings of embarrassment, guilt, regret, and desire for social isolation may also be exacerbated by the stimulation of other negative emotions. (Gratz, 2003) It has been suggested that there may be many biological factors under self-harm behavior. Some of them are opiate system disorder, hypersensitivity of dopamine receptors, decrease in the amount of serotonin. There are psychodynamic opinions about self-harm behavior. Emerson (1913) and Fenichel (1945) stated that self-harm behavior is a substitute for masturbation and is equivalent. Then, behaviorists related to self-harm behavior started to study. According to the behavioral approach, self-harm behavior was later learned and considered as a sense of self-protection against the difficulties of life.

 Intentional self-harm behavior is difficult to explain, but in recent years it has attracted attention by researchers (Chapman, Gratz, & Brown, 2006). In line with the literature review on the subject, it is seen that the studies on this subject need to be more detailed and more specialized case groups should be examined.
