Pengaruh Sudut Serang Aerofoil Terhadap Distribusi Tekanan dan Gaya Angkat
Authors: Wibowo Heri
Published: December 2017

The aerofoils are used to get the lifting force on the design of plane’s wings. The lifting force is caused by difference air velocity on upper and lower aerofoil which the magnitude depend on attack angle of aerofoil and air velocity exist surrounding. This experiment aims to show the force vector (pressure distribute) on the aerofoil. The aerofoil is attached by air with konstant velocity. The research procedure is done by change the attack angle of aerofoil on five formation. The surface of aerofoil is connected with pressure gage which disperse at 11 point of measurement. The result shows that magnitude of force vector is depended on attack angle of aerofoil. Increasing angle of aerofoil until boundary angle will be followed by increasing air velocity on the point of measurement and finally increase force vector. Upper boundary angle will be followed by decreasing air velocity and finally decrease force vector.Aerofoil digunakan untuk mendapatkan gaya angkat pada desain sayap pesawat. Gaya angkat disebabkan oleh perbedaan kecepatan udara pada aerofoil atas dan bawah yang besarnya tergantung pada sudut serang aerofoil dan kecepatan udara yang ada disekitarnya. Eksperimen ini bertujuan untuk menampilkan vektor gaya (distribusi tekanan) pada aerofoil. Aerofoil dilekatkan pada udara dengan kecepatan konstan. Prosedur penelitian dilakukan dengan cara mengubah sudut serang aerofoil pada lima formasi. Permukaan aerofoil dihubungkan dengan alat ukur tekanan yang tersebar pada 11 titik pengukuran. Hasil menunjukkan bahwa besarnya vektor gaya bergantung pada sudut serang aerofoil. Sudut aerofoil yang meningkat hingga sudut batas akan diikuti dengan peningkatan kecepatan udara pada titik pengukuran dan akhirnya meningkatkan vektor gaya. Sudut batas atas akan diikuti oleh penurunan kecepatan udara pada titik pengukuran dan akhirnya menurunkan vektor gaya.

The Educational Role of Philosophy (with a new commentary by Phillip Cam)
Authors: Lipman Mat
Published: December 2017

The history of the relationship between philosophy and education has been a long and troubled one. In part, this stemmed from the problematic nature of philosophy itself, but this difficulty was compounded by controversy as to the age at which training in philosophy should begin. Although Socrates seemed indifferent to whether he conversed philosophically with young or old, his pupil, Plato, was inclined to restrict philosophy to mature students, on the grounds that it made the younger ones unduly contentious. Since philosophers in those days had the reputation of being ‘friends of wisdom,’ and since being a friend of wisdom seemed to require extensive experience, it came to be taken for granted, generation after generation, that philosophy was not for the young. It has sometimes been made available, on a limited basis, at the secondary school level, but almost never to students in the lower grades. To the suggestion that this prevented children from having access to ideas, theories and abstract concepts, the stock response was that children were mired in the ‘concrete’ level of experience and had no interest in abstractions. To the report that very young children almost invariably greeted opportunities to discuss philosophy with joy and delight, the standard reply was that this proved that the children could not be doing philosophy, since the study of philosophy is a serious and difficult matter. The recent career of philosophy in elementary and secondary education has been a matter of overcoming precisely these objection and misconceptions. Unfortunately, a listing of the advantages to be derived by the young from the study of philosophy—its strengthening of reasoning and judgment, its fostering of concept-formation skills, its clarification of values and ideals—is likely to obscure the intrinsic satisfactions that children derive from their classroom communities of philosophical inquiry. But even here there are signs of change, and a new appreciation of the educational possibilities of philosophy is at last beginning to surface in the schools.
Democratic Pedagogy
Authors: Burgh Gilbert
Published: December 2017

The ideas contained in this paper were first formulated as part of a chapter in my doctoral dissertation, which was completed in 1997.  Some years later I added to my initial thoughts, scribbled some notes, and presented them at the 12th Annual Philosophy in Schools Conference, held in Brisbane in 2002. This presentation surfaced as a paper in Critical & Creative Thinking: the Australasian Journal of Philosophy in Schools (Burgh 2003a). Soon thereafter I revised the paper (Burgh 2003b) and it appeared in abridged form in the Asia-Pacific Philosophy Education Network for Democracy (APPEND) Philosophy Series, Volume 4: Philosophy, Democracy and Education, edited by Philip Cam. It was once again revised, but also expanded, and appeared in Chapter 5 of Ethics and the community of inquiry: Education for deliberative democracy, a collaborative authorship with Terri Field and Mark Freakley (2006). Some sections have been further revised and appear in other publications (Burgh 2009, 2010; Burgh & Yorshansky 2011). These revisions would suggest that my thoughts on these matters are constantly changing. To some degree this is true, but each time the changes have built on previous ideas rather than new ideas replacing old ones. I welcomed the invitation to revise the original paper, which includes sections not included in later versions. However, with almost 11 years passing since the original publication, I found myself deleting sections and replacing others. Subsequently, this paper is a culmination of all the revisions and incorporates ideas from each.
Kung Fu as critical thinking: An ethnographic analysis
Authors: Habimana Olivier , Stambach Amy
Published: December 2017

This paper offers an alternative view of critical thinking beyond that which stresses student-centered instruction. It draws on participant-observation and interview data collected from a Kung Fu course held at the University of Rwanda to highlight how students use Kung Fu to make decisions in other domains of their lives. Analysis suggests that direct instructional modes facilitate students’ independent reasoning and their approaches to problem solving. In exploring how Rwandan students apply Kung Fu, the paper questions whether critical thinking and student-centered activities necessarily go hand-in-hand.
Philosophy for Children and the ‘whole child’
Authors: Lamb Winifred
Published: December 2017

The notion of educating the ‘whole child’ invites suspicion because of the value-laden assumptions carried by such a goal. I argue that the intuitive appeal of the notion reflects the meaning of education but that the goal is also implicit in P4C in its respect for wholeness in content, rationale and practices whereby the learner is honoured and engaged. In this paper, I focus on the senior high school curriculum in which the rich resources of philosophy can speak to the broad range of students’ questions and concerns: intellectual, existential and social, addressing (and challenging) their ‘whole’ persons with its legacy of wisdom.
Book review - Identity and personhood: Confusions and clarifications across disciplines
Authors: D'Olimpio Laura
Published: December 2017

Splitter commences this book by telling the reader that it was a pedagogical incident that led him to write it. Presenting a philosophical seminar series on the topic of ‘identity’ to bright undergraduate students in America from a range of disciplines heightened his realisation that we don’t all use the word in the same way to refer to the same thing. We wouldn’t normally think too much about it, assuming that identity, especially one’s own, is an obvious, assumed entity. However, it is not, really, the closer you examine the concept. Which is precisely what Splitter goes on to do.
Cultural DeCoding: A humanities program for gifted and talented high school students seeking university entrance
Authors: D'Olimpio Laura , McCarthy Angela , Pedersen Annette
Published: December 2017

This article details Cultural DeCoding, a humanities based high school extension program for gifted and talented Year 11 and 12 students in Western Australia. The brainchild of Dr Annette Pedersen (UWA & John XXIII College) and Dr Angela McCarthy (UNDA), the program runs for four days across the summer holidays before the start of the school term. The program fills a gap that exists in the education of gifted and talented secondary students who are interested in the humanities. It is comprised of sessions run by academics who facilitate discussion and activities based on their area of research and teaching expertise. The group is deliberately kept small in order to give students a chance to engage deeply and respectfully with like-minded others. The intention is to give these students an experience of what university will be like, and to have a chance to think philosophically; namely, critically, creatively and morally, in collaboration with others.

Philosophy in Schools: An introduction for philosophers and teachers edited by Sara Goering, Nicholas J Shudak and Thomas E Wartenberg (2013). (Routledge Studies in Contemporary Philosophy) Taylor & Francis, New York, NY. ISBN: 9780415640633. The edited collection Philosophy in Schools: An introduction for philosophers and teachers is exactly that; an introduction to the central ideas of the Philosophy in Schools movement, with tips and strategies as to how to implement Philosophy for Children (P4C) in your classroom or educational space. With 25 chapters, this handy edition includes the writings of 31 academics and well known practitioners of P4C worldwide. While all the voices contributing to this volume are positive and optimistic as they exalt the benefits of P4C, the diversity comes in the form of the various ways in which the numerous authors have practiced philosophy with participants of different ages, cultural and socio-economic backgrounds. There is a mix of theory and pedagogy, with a focus on the pragmatic reality of doing philosophy with young people.
Book review - 40 lessons to get children thinking: Philosophical thought adventures across the curriculum
Authors: Sprod Tim
Published: December 2017

Peter Worley’s latest book provides a wealth of interesting and engaging lessons based around the pedagogy of philosophical discussions in the classroom. The book’s subtitle references the curriculum, and indeed the book contains ‘thought adventures’ to deepen and enliven learning in many of the subjects taught in schools. While the curriculum in question is pretty clearly the National Curriculum in England, none of the lessons are so closely tied to the details of that curriculum that they could not be used in other countries.

Published: December 2017

Prevalence of hypertension in Indonesia  has reached 25.8%; Yogyakarta is the third largest prevalence in Indonesia, and hypertension in Seyegan sub-district is ranked first most diagnosed. Hypertension can lead to an increased risk of cardiovascular diseases such as heart attacks and strokes. Knowledge related to hypertension of residents, especially youth is still quite low. Youth is provided with education and training on how to measure blood pressure and basic knowledge related to hypertension. The education was done by discussion using Focus Group Discussion (FGD) method, then youth made program to overcome hypertension problem. Conducted blood pressure screening and interviews about the lifestyle of residents to determine the cause of hypertension. Blood pressure screening and interviews were analyzed by chi square or fisher, increased youth knowledge from pre-test and post-test analyzed with kolmogorov-smirnov and analyzed by paired T test with 95% confidence level. There was no significant effect between BMI, education and exercise on blood pressure, but there was a significant influence between smoking and consumption of foods high in salt and fat to blood pressure. The results of pre-test and post-test showed an increase in youth knowledge from the beginning only 5.27 to 7.37 with p-value 0.000 (p <0.05). Provision of education to youth increases the level of knowledge related to hypertension.
Knowth passage-grave in Ireland: An instrument of precision astronomy?
Authors: Prendergast Kate
Published: December 2017

Knowth is one of three large monuments at the Neolithic complex in the bend of the River Boyne in County Meath, Ireland. The others are Newgrange and Dowth. All three have obvious solar alignments but whereas the alignment to the winter solstice sunrise at Newgrange has been extensively researched and interpreted, little has been attempted regarding the way that astronomy functions at Knowth and Dowth. This paper treats the evidence for solar and lunar alignments at Knowth.

Knowth has two internal passages with entrances at the east and west. The paper draws on new surveys as well as interpretations of the evidence at Knowth that includes rock art engraved on kerbstones around the circumference. Particular engravings on kerbstone K52 are interpreted as depicting astronomical cycles. It is argued that, while Knowth’s passages function in relation to the equinoxes, they are not internally orientated to match exactly the equinoctial directions. Rather, it seems that they may have been constructed and used to facilitate the harmonisation of the solar and lunar cycles - much in the same way as does the equinoctial Judeo-Christian festival of Easter. The paper concludes by suggesting that like Newgrange, Knowth may be an astronomical instrument that enabled its builders and users to construct accurate calendars and counting systems, which in turn facilitated calculated planning and was a fundamental structuring principle for their ritual lives and cosmological beliefs.
ÍNDICE DE BEM-ESTAR ECONÔMICO: UMA PROPOSTA PARA OS ESTADOS BRASILEIROS
Authors: Vidigal Cláudia Bueno Rocha , Kassouf Ana Lucia , Vidigal Vinícius Gonçalves
Published: December 2017

O presente artigo tem por objetivo a construção de um Índice de Bem-Estar Econômico (IBEE) para as unidades da federação brasileira, considerando os anos de 2002 e 2008. Especificamente, busca-se verificar os níveis de bem-estar econômico e de seus subcomponentes, além de compará-los entre os estados brasileiros. O índice proposto foi composto por quatro dimensões distintas: “Fluxos de consumo”, “Riqueza real – Legado intergeracional”, “Equidade” e “Seguridade econômica”. Os principais resultados demonstraram que, independentemente da ponderação utilizada, Santa Catarina foi o estado brasileiro que apresentou o maior bem-estar econômico em relação aos demais. Por outro lado, Alagoas foi o estado com pior desempenho, ocupando a última posição do ranking em todas as análises. Considerando a necessidade de construção de uma medida sintética de bem-estar econômico e tendo em vista a relevância de indicadores para subsidiar a implementação e monitoramento de políticas públicas, o IBEE apresenta-se como um índice capaz de mensurar de maneira mais adequada os distintos aspectos associados a um padrão de vida decente.

Justiça, Cordel e Democracia:
Authors: Cruzes Maria Soledade Soares
Published: December 2017

No Estado liberal, o acesso à justiça pautava-se numa ótica individualista e, paradoxalmente,inacessível a determinados atores sociais. Por outro lado, na conjuntura democrática, perpassa por umaabordagem tanto individual quanto coletiva, social e comunitária. A Literatura de Cordel, tão difundida nonordeste brasileiro, é escrita em forma rimada, métrica, regionalizada e em linguagem democraticamenteacessível, com textos publicados em livretos. É nesse contexto que se apresenta o problema central dapesquisa: em que medida é possível analisar a democratização do acesso à justiça no Brasil à luz da literaturanordestina de Cordel? Trabalha-se com a hipótese de que é possível utilizar da Literatura de Cordel parainvocar análise crítica de obstáculos ao acesso democrático à justiça, como a burocracia, a morosidade, aseletividade, a educação e o formalismo linguístico. Trata-se de pesquisa bibliográfica, de cunho exploratório,desenvolvida por meio da análise interdisciplinar e crítica de folhetos de Literatura de Cordel, textos legislativos,constitucionais e obras relacionadas à linguagem, leitura, educação e Direito.
Escola técnica, conhecimento integrado e politecnia
Authors: Rocha Ione Dos Santos , De Almeida José Rubens Mascarenhas
Published: December 2017

O artigo aqui apresentado objetiva discutir a trajetória das escolas técnicas brasileiras diante da proposição de ensino integrado da legislação vigente e aprofunda a discussão acerca da politecnia como proposta de superação da dualidade entre trabalho intelectual e manual.  A partir deste objetivo, são analisadas as contradições, desde o surgimento à distribuição, das instituições públicas de ensino técnico e a trajetória do estabelecimento desta rede de ensino até a atualidade, retratando a apropriação política da educação como mecanismo de promoção das demandas econômicas. Nesse sentido, o debate acerca do conceito de politecnia, que corresponde a uma concepção de educação mais profunda a partir da apropriação da tecnologia como conhecimento e produção social, é um desafio dos cursos técnicos integrados em vigor nas escolas atuais.
O produtivismo acadêmico como expressão da precarização do trabalho docente
Authors: De Mello Fábio Mansano , Santos Alves Ana Elizabeth
Published: December 2017

O presente artigo tem por escopo apontar os limites da qualificação do trabalho docente, que está cada vez mais precarizado por meio da intensificação, rotinização e do controle ao qual o mesmo é submetido pelo metabolismo capitalista. Num primeiro momento refletimos sobre os conceitos de desqualificação e precarização do trabalho, passando pela ideia da proletarização docente; em seguida, demonstramos como o produtivismo acadêmico é uma expressão concreta da sanha capitalista em potencializar o lucro e consolidar a educação superior como uma rentável mercadoria.

Indicators influencing performance and stability in GCC banking sector
Authors: Alharthi Majed
Published: December 2017

The main objective of this study is to identify the factors that can impact on the profitability and stability of GCC banks, using data from the period 2005-2014, to achieve GCC Vision 2030. The profitability indicators are: return on assets (ROA), return on equity (ROE), and net interest margin (NIM). In terms of stability, this can be presented through z-score and capital ratio. The statistical regressions in this study are generalised least squares (GLS) and generalised method of moments (GMM). Using both statistical indicators (GLS and GMM) is highly limited in previous studies. The main results for profitability show that stable banks are typically more profitable than instable banks. Moreover, there is a significant and positive correlation between capital ratio and profits – larger banks obtained higher returns. To achieve GCC Vision 2030, GCC banks may benefit from concentrating on lending services. Furthermore, attracting foreign direct investments can enhance banks’ profits. In contrast, outflow remittances badly affect ROA and ROE. As for the findings of stability, z-score and capital ratio impacted each other significantly and positively. Additionally, larger banks were found to be more risky when compared to smaller banks, and lending services support stability with lower insolvency risks. Finally, ROA significantly and strongly affects both stability indicators (z-score and capital ratio). Using the foreign direct investment (FDI) as an independent variable is a contribution to the performance and stability studies in banking. The result indicates that more FDI leads to better profitability in banking sector. In addition, examining the effects of outflow remittances on performance and stability adds to the knowledge. The outflow remittances decreased ROA and ROE but improve NIM significantly. In general, Islamic banks could achieve more profits (with higher insolvency risks) than conventional banks, and are found to be well-capitalised compared to conventional banks

Published: December 2017

É imprescindível conhecer a percepção e satisfação de pacientes quanto à alimentação hospitalar para evitar a redução da ingestão alimentar e consequente depleção do estado nutricional. O objetivo do presente artigo foi analisar o grau de satisfação e a percepção sensorial e extrassensorial dos pacientes em relação à alimentação em um hospital filantrópico localizado no Centro-Oeste do Estado do Paraná. Trata-se de um estudo transversal, exploratório, com abordagens quantitativa e qualitativa. Para a coleta de dados, foram utilizados os seguintes instrumentos: análise documental de prontuários, entrevista semi-estruturada e enquete de satisfação acerca das refeições do hospital. Os resultados mostraram satisfação com o horário em que as refeições são servidas, a temperatura e a quantidade de comida e insatisfação com o sabor e consistência das refeições. Conclui-se que, de modo geral, há satisfação com as refeições servidas, no entanto, as percepções dos pacientes, indicam insatisfação com aspectos que não puderam ser percebidos quantitativamente, como o ambiente, a aparência e a textura da comida servida.

Dynamika rozwoju agroturystyki zależy w dużym stopniu od działań marketin­gowych, w tym promocji usług. Wielu właścicieli gospodarstw agroturystycznych wykorzystuje witryny internetowe do prezentacji swojej oferty i dotarcia z nią do szerszego grona odbiorców. Takie atrybuty witryny jak: użyteczność, funkcjonalność, interaktywność i wydajność są często postrzegane jako obietnica wysokiej jakości oferty, z której klient rozważa skorzystać. Celem pracy był pomiar wydajności witryn internetowych gospodarstw agroturystycznych. Badania miały charakter pilotażowy i zostały wykonane w zbiorze 100 witryn internetowych, których adresy pozyskano w wyszukiwarki Google oraz jednego z ogólnopolskich katalogów. Testy wy­dajności wykonano za pomocą wybranych aplikacji internetowych. Ponadto wytypowano strony o skrajnych parametrach, które poddano szczegółowej analizie. W konkluzji wykazano, że witry­ny internetowe gospodarstw agroturystycznych charakteryzowały się zadowalającym stopniem wydajności, co nie zawsze jednak korespondowało z ich efektywnością i jakością wykonania.
Tendencje na rynku mięsa wieprzowego na świecie i w Polsce w latach 2000-2016
Authors: Stańko Stanisław , Mikuła Aneta
Published: December 2017

Opracowanie przedstawia zmiany na rynku wieprzowiny na świecie i w Polsce w latach 2000-2016. Analizowano zmiany u największych jej producentów i konsumentów, a także eksporterów i importerów. Do głównych światowych producentów wieprzowiny należą: Chiny, kraje UE, USA, Brazylia, Rosja i Wietnam, które w 2016 r. skupiały 88,2% światowej produkcji. U głównych światowych producentów wieprzowiny (z wyjątkiem Chin) wzrost konsumpcji był wolniejszy niż produkcji, co spowodowało zwiększenie ich możliwości eks­portowych. W latach 2000-2016 tempo wzrostu handlu międzynarodowego było szybsze niż produkcji, co skutkowało wzrostem udziału eksportu w zagospodarowaniu produkcji. Źródła światowego eksportu wieprzowiny charakteryzowały się znaczną i rosnącą koncentracją. W 2016 r. z krajów UE pochodziło 37,6% eksportu, z USA 28,5%, z Kanady 15,9% i z Brazylii 10%. (92% ogółu eksportu). Światowy import wieprzowiny charakteryzował się znacznie więk­szym rozproszeniem niż eksport. Ceny wieprzowiny wykazały tendencję wzrostową. W kraju występowała tendencja spadkowa w produkcji, a wzrostowa w konsumpcji, co spowodowało, że od 2008 r. Polska jest importerem netto wieprzowiny

Published: December 2017

W artykule przedstawiono ocenę motywowania pracowników wykonawczych w spółkach hodowlanych należących do Agencji Nieruchomości Rolnych. W ocenie tej sku­piono się na określeniu stopnia zaspokojenia oczekiwań pracowników, rozpoznaniu hierarchii ważności podstawowych motywów pracy oraz ocenie umiejętności kadry kierowniczej dotyczących motywowania pracowników. Z przeprowadzonych badań wynika, że gros ocze­kiwań pracowników nie było w pełni zaspokajanych. W największym stopniu dotyczyło to oczekiwań związanych z podwyżką wynagrodzeń oraz awansem. Najważniejszymi motywami wykonywania pracy okazały się wysokość wynagrodzenia oraz pewność posiadania pracy. Umiejętności kadry kierowniczej dotyczące motywowania pracowników były na średnim poziomie. W motywowaniu pracowników kadra kierownicza zbyt mało wagi przywiązywała do indywidualnego rozwoju zawodowego poszczególnych pracowników.

Authors: Zhao Yijun , Feng Dongdong , Sun Shaozeng , Luan Jiyi , Che Hongwei
Published: December 2017

The cyclonic gasification technology could realize self-separation of syngas and residual carbon, simplifying the purification system. In cyclone pyrolysis-suspension combustion system, bottom air was fed into carbon-rich area of gasifier. Due to the high height/diameter ratio and uneven temperature distribution in cyclone gasifier, the primary/secondary/bottom air rates were 30%, 20%, and 50%, respectively. Effects of gasification intensity and air equivalent ratio on rice husk gasification performance were explored. The results show that for cyclone pyrolysis-suspension combustion, the optimum gasification intensity is 885.24 kg/m2h. Strengthening the subregion of air supplement could cause a gradual increasing of temperature along the axis of gasifier. The syngas yield was independent of gasification intensity, but increased from 0.98 Nm3/kg at ER = 0.23 to 1.38 Nm3/kg at ER = 0.32. At ER = 0.26~0.29, the gasification performance is best, with gas heat value of 4.99~5.37 MJ/Nm3, cold gasification efficiency of 48.25~49.67% and tar content of 5.38~5.75 g/Nm3.
Investigation on drag coefficient of supercirtical water cross-flow past cylinder biomass particel at low Reynolds numbers
Authors: Wu Zhen-Qun , Jin Hui , Ren Yi-Fei , Guo Lie-Jin
Published: December 2017

The supercritical water gasification of biomass technology is a promising approach for the efficient and clean conversion of wet-biomass to hydrogen-rich gas production. Many of the biomass materials are of rodlike shape and gasified in supercritical water fluidized bed. So the particle-fluid two-phase flow behaviors insider supercritical water fluidized bed are of great importance. Constrained by the extreme operating condition, numerical methods, such as the Euler-Euler method and Euler-Lagrange method, are used to study the flow behaviors inside the supercritical water fluidized bed. As the accuracy of these methods are depended on the drag force model and there is little investigation on that at supercritical condition, this work is focused on the drag coefficient of cylinder biomass particle with different ratio of length to diameter. The simulated results show that there is no differ- ence for the drag coefficient of a certain particle at different condition when the Reynolds number is same. The variation tendency of the pressure and viscous drag coefficient with Reynolds number and the ratio of length to diameter is also given in this paper.

Background/Aim. New and improved definition of dry eye disease (DED) emphasized that hiperosmolarity and inflammation with initial tear film instability play etiological role. The aim of this study was to explore relation of some commonly used clinical tests to dry eye disease (DED) related inflammation measured by conjunctival scraping cytology. Methods. We examined 100 subjects, 80 of them having DED. We performed Schirmer without anesthesia (Schirmer I), Fluorescein Tear Break Up Time (FTBUT), Rose Bengal (RB), Lid Parallel Conjunctival Folds (LIPCOF), Tear Meniscus Height (TMH) and Tear Ferning (TF) and compared the values to scraping scores of tarsal conjunctiva. Results. FTBUT had the best sensitivity (93.6%). The highest specificity was found with RB (93.2%), but it was also high with Schirmer I, TF and FTBUT (respectively 89.8%, 84.5%, 78.0%). RB and FTBUT had the highest correlation with conjunctival scraping score (r = 0.707, p < 0.001; r = -0.507, p < 0.001). Conclusion. In our study, FTBUT, though often used in many combinations of the DED tests, showed a remarkably high sensitivity and specificity on its own, as well as good correlation with DED related inflammation detected with conjunctival scraping cytology.
Formation mechanisms of pores and spatters during laser deep penetration welding
Authors: Volpp Joerg
Published: December 2017

During laser deep penetration welding process, defects cannot be completely avoided yet. Due to the dynamic process, especially process pores and spatters occur. Keyhole dynamics are assumed to be responsible for the initiation of both pores and spatters. However, it is not completely clear yet how spatters and pores are formed. A semianalytical model of a keyhole is used to simulate dynamic keyhole properties of laser beam welding of aluminum. These are related to characteristics of spatters and pores occurring during laser deep penetration welding recorded using high-speed-imaging technique and x-ray analysis, respectively. Correlations of keyhole shapes and pore formation show that the volume underneath a keyhole collapse can be sufficient to capture the gas that is necessary for the formation of a pore and a keyhole expansion is not necessarily needed to produce the pores found in the weld seam. Calculated keyhole wall fluctuations are found to be not sufficient to detach spatters from the keyhole wall without additional forces from the melt pool.

A number of experimental investigations on fibre reinforced polymer (FRP), with the aim of understanding their behaviour when applied as strengthening of reinforced concrete elements, are available in the literature but very few information is available on strengthening real-scale elements with cementitious composites. In particular design code formulations are scanty or non-existent.In this study the behaviour of four precast pre-stressed TT beams taken from an existing industrial building was investigated. One of them was considered as control unstrengthened TT beam, whereas the others were strengthened with different techniques, namely with FRP laminates (glued with epoxy resin), carbon fibres with cementitious matrix and steel fibres with cementitious matrix. Each material involved in this study was also mechanically characterized to obtain the main physical properties. Adequate specimens were obtained from the existing TT beam to characterize the concrete and the reinforcing steel bars.
Criterio columna fuerte viga débil en edificios de baja altura
Authors: Barros Cabezas José , Santa María Hernán
Published: December 2017

En la presente investigación se plantea que, para edificios de pórticos de hormigón armado de dos pisos o menos, la revisión del criterio “columna fuerte-viga débil” realizada siguiendo las recomendaciones de la Norma Ecuatoriana de la Construcción (NEC 2011), aplicando una simplificación, es más adecuada que la metodología que propone el código ACI 318-11, en términos de optimización de materiales (específicamente, acero de refuerzo longitudinal), manteniendo una seguridad y desempeño estructural muy similares.Para demostrar esto, se realiza lo siguiente: primero, un diseño de un edificio con cada una de las normas antes mencionadas con el objetivo de comparar las cantidades de acero de refuerzo longitudinal requeridas, y luego análisis no lineales estáticos (pushover) y dinámicos (tiempo historia), con el objetivo de revisar las formas de falla para cada diseño y la probabilidad de colapso correspondiente al sismo máximo considerado (MCE por sus siglas en inglés) definido por la norma ASCE/SEI 7-10, siguiendo las recomendaciones de modelaje numérico y análisis propuestos en la metodología FEMA P-695.Se demuestra que la reducción de cantidades de acero de refuerzo que se logra utilizando los criterios de la norma NEC con una modificación, no afecta de manera significativa el desempeño de estas estructuras, manteniendo la probabilidad de colapso dentro de los límites sugeridos en la metodología FEMA P-695.
Evaluation of collapse mechanisms in masonry buildings: critical overview and case histories
Authors: Di Tommaso Angelo , Casacci Susanna
Published: December 2017

In recent years the approach to the analysis of seismic vulnerability of masonry buildings considers as crucial the evaluation of potential local mechanisms. The “fracture” lines depicted on the wall (when it is “compact”) can show its labile condition of equilibrium and point out the potential kinematic of relative motion among blocks. The analytical evaluation of kinematics, linear and non-linear, presents some aspects that could be analysed with criticism.Among the techniques to contrast the potential mechanisms some very effective ones could be considered: plating with composites (covered by plaster) or reinforced re-pointing.Basic criteria to apply it and analytical procedures to determine the level of upgrading are considered in detail.This paper will analyse some of these aspects with reference to actual cases of study (Pavarotti theatre and San Barnaba Church in Modena, and campanile in Reno Centese, Ferrara, Italy).

Case studies on strengthening of concrete and masonry structures
Authors: Nanni Antonio , Prota Andrea
Published: December 2017

This paper presents a number of case studies related to the strengthening of concrete and masonry structures damaged by the April 6, 2009, Mw 6.3 earthquake that struck the Italian city of L’Aquila and surrounding localities. After a brief overview of the existing challenges in buildings constructed prior to 1972 when the first building code addressing seismic construction was enacted in Italy, the paper describes interventions using technologies that can be considered innovative in that they are not addressed in the majority of the current building codes worldwide. The following strengthening methods are described: a) fiber-reinforced polymer (FRP) composites in the forms of manual lay-up, procured laminates and spikes; b) steel-reinforced polymer (SRP) lay-up and spikes; and, c) fabricreinforced cementitious matrix (FRCM). The paper concludes with a description of how the deployment of innovation for construction takes place in the United States. This example is intended to identify challenges to innovation and a possible method to overcome them.

Uso de amortiguador de masa sintonizada en ingeniería estructural: edificio parque Araucano en Santiago de Chile
Authors: Breschi Leopoldo , Castillo Arturo
Published: December 2017

La aplicación de Amortiguador de maza sintonizada en ingeniería mecánica es de uso corriente y larga data. Para este tipo de aplicaciones, las solicitaciones son de frecuencias constantes y conocidas. Sin embargo su aplicación en estructuras ha comenzado hace pocos años, bajo el concepto general de protección sísmica.El diseño de un Amortiguador de Masa Sintonizada para un edificio conlleva la dificultad práctica de sintonizar éste apropiadamente al periodo fundamental de la estructura. A través de la incorporación de amortiguamiento adicional, es posible ampliar el rango de frecuencias de sintonía y por ende hacer más efectivo el uso de un AMS.Por otro lado, las excitaciones a las que se verá sometida la estructura son inciertas en cuanto a su distribución de frecuencias, esto conlleva la posibilidad cierta de generar un efecto contraproducente, ya que las respuestas pueden incluso ser peores con el uso del AMS. La incorporación de mayor amortiguamiento pese a que disminuye la eficiencia especialmente en el período fundamental, produce una mejor respuesta para todo el rango de frecuencias de dichas excitaciones.El siguiente trabajo muestra en términos teóricos y prácticos la aplicación de este concepto en un edificio construido el año 2006 en Santiago de Chile, sometido a los efectos del sismo de magnitud 8,8 Mw e intensidad VIII de la región del Maule el año 2010.
Os camponeses russos sob o olhar da intelligentsia revolucionária
Authors: Arbex Junior José
Published: December 2017

No verão de 1874, milhares de estudantes abandonaram os bancos das salas de aula das universidades de Moscou e São Petersburgo para irem ao encontro dos camponeses russos. Inspirados pelas teorias românticas de autores como Herzen e Tchernichevski, por debates mantidos por publicações da intelligentsia russa como a Vpieriod, de Lavrov; Nabat, de Tkatchov; Narodnoe Delo, de Bakunin; Otietchestvienniie Zapiski, de Mikhailovski; jovens universitários lançaram a campanha “ir ao povo” para trabalhar, comer e vestir-se como os muzhiki russos. O intuito desses militantes era transformar a realidade russa por meio de uma “atividade social” (fortalecer as comunas rurais e criar cooperativas, por exemplo) e não através da “prática política” de Estado (luta por reformas políticas do regime czarista).
