Multi-Objective Optimisation of Laser Deposition of Metal Matrix Composites for Surface Coating Using Principal Component Analysis
Authors: Farayibi Peter Kayode
Published: December 2018

Laser deposition is an advanced manufacturing technology capable of enhancing service life of engineering components by hard-facing their functional surfaces. There are quite a number of parameters involved in the process and also desirable output characteristics. These output characteristics are often independently optimised and which may lead to poor outcome for other characteristics, hence the need for multi-objective optimisation of all the output characteristics. In this study, a laser deposition of Ti-6Al-4V wire and tungsten carbide powder was made on a Ti-6Al-4V substrate with a view to achieve a metallurgical bonded metal matrix composite on the substrate. Single clads were deposited with a desire to optimise the composite clad characteristics (height, width and reinforcement fraction) for the purpose of surface coating. Processing parameters (laser power, traverse speed, wire feed rate, powder feed rate) were varied, the experiment was planned using Taguchi method and output characteristics were analysed using principal component analysis approach. The results indicated that the parameters required for optimised clad height, width, and reinforcement fraction necessary for surface coating is laser power of 1800 W, traverse speed of 200 mm/min, wire feed rate 700 mm/min and powder feed rate of 30 g/min. The powder feed rate was found to most significantly contribute 43.99%, followed by traverse speed 39.77%, laser power 15.87% with wire feed rate having the least contribution towards the multi-objective optimisation. Confirmation results showed that clad width and reinforcement fraction were significantly improved by the optimised parameters. The multi-objective optimisation procedure is a useful tool necessary to identify the process factors required to enhance output characteristics in laser processing.

Published: December 2018

The objective of this study was to evaluate the water quality of Carahá River in Lages (Brazil), using the concept of pollutant load and comparing the results with the water quality index. Thirteen points along the river were selected and eight collections were carried out over a period of 16 months. The parameters analysed were those required for the calculation of the water quality index (WQI). Flow measurements were also carried out, which enabled the calculation of the polluting load. The results showed that the WQI score ranges between 24.95 at the source and peaks at 40 at the outlet. The water classification, therefore, ranges from “very bad” to “bad”. The calculation of the pollutant load showed a constant disposal of contaminants into the river, which demonstrates that the quality of the water is continuously degraded. This information could not be obtained by analysing only the WQI, which presented a nearly constant quality at point 4 and beyond. The use of the calculation of pollutant load for Carahá River is, therefore, a tool for assessment of pollution that can provide more appropriate information for the water resources management.

Published: December 2018

In this study, baker’s yeast-MnO2 composites, produced by direct oxidation of yeast with KMnO4 under acidic conditions, were used as biosorbent to remove the triphenylmethane dye Malachite green (MG) from an aqueous solution. Parameters that influence the adsorption process, such as pH, contact time, temperature, initial dye concentration and biosorbent dosage, were evaluated in batch experiments. The optimum removal of MG was found to be  86.7 mg g-1 at pH 10, 1.0 g L-1 of biomass dosage and 45°C. The kinetic data of dye removal was better described by the pseudo-second-order model. The adsorption process followed the Langmuir isotherm model and the maximum biosorption capacity was estimated to be  243.9 mg g-1 (at 25°C). The negative values of ∆G° and the positive value of ∆H° indicated that the MG biosorption onto yeast-MnO2 composites is spontaneous and endothermic. Fourier transform infrared spectroscopy (FTIR) indicated that the nano-MnO2 particles deposited on yeast-MnO2 composites surface facilitated the MG adsorption. It was concluded that baker’s yeast-MnO2 composites have potential for application as adsorbent for removal of MG from aqueous solution.
Identification Key for the Chagas Disease Vectors of Five Brazilian States, Based on Cytogenetic Data
Authors: Borsatto Kelly Cristine , Vilela Azeredo-Oliveira Maria Tercília , Alevi Kaio Cesar Chaboli
Published: December 2018

Chagas disease is a public health problem caused by the protozoan Trypanosoma cruzi that affects about 8 million people worldwide. The main form of transmission of T. cruzi is vectorial, through triatomines feces contaminated with the parasite. All species are considered as potential vectors of T. cruzi. The main identification keys of these vectors are based only on morphological characters. However, there are very similar or even same species (cryptic species) that may lead to wrong classification of the vectors. Therefore, we developed an identification key using cytogenetic data, to aid and help the correct classification of triatomines. From the cytogenetic characters, identification keys were created for the five Brazilian states (Alagoas, Amapá, Ceará, Roraima, and Santa Catarina). These data are important because the correct classification of triatomines helps directly the activity of the vector control programs.

The aim of our study was to describe the clinical features, the etiologies, and the factors associated with poor outcome of encephalitis in French Guiana. Our study was retrospective, including all cases of encephalitis hospitalized in the Cayenne General Hospital, from January 2007 to July 2017. Patients were included through the 2013 encephalitis consortium criteria and the outcome was evaluated using the Glasgow outcome scale at 3 months from the diagnosis of encephalitis. We included 108 patients, giving an approximate incidence rate of four cases/100,000 inhabitants/year. The origin of the encephalitis was diagnosed in 81 cases (75%), and 72 of them (66.7%) were from an infectious origin. The most common infectious causes were Cryptococcus sp. (18.5%) independently of the immune status, Toxoplasma gondii (13.9%), and Streptococcus pneumoniae (5.5%). In the follow-up, 48 patients (46.6%) had poor outcome. Independent risk factors associated with poor outcome at 3 months were “coming from inside area of the region” (P = 0.036, odds ratio [OR] = 4.19; CI 95% = 1.09–16.06), need for mechanical ventilation (P = 0.002, OR = 5.92; CI 95% = 1.95–17.95), and age ≥ 65 years (P = 0.049, OR = 3.99; CI 95% = 1.01–15.89). The most identified cause of encephalitis in French Guiana was Cryptococcus. The shape of the local epidemiology highlights the original infectious situation with some local specific pathogens.

Published: December 2018

We compared the impact of annual and semiannual mass drug administration (MDA) on the prevalence of Brugia timori and Wuchereria bancrofti in Flores Island. Two villages (Paga, B. timori only; Lewomada, co-endemic) received annual MDA with diethylcarbamazine/albendazole and a larger village (Pruda, co-endemic) received semiannual MDA. Infection parameters (microfilariae [Mf], antibodies to recombinant filarial antigen BmR1 [Brugia Rapid (BR)], and a test for W. bancrofti antigenemia [immunochromatographic test (ICT)]) were assessed before and after treatment. The crude Mf prevalence in Pruda decreased after five semiannual treatments from 14.2% to 1.2%, whereas the Mf prevalence in the other two villages decreased after three annual treatments from 3.9% to 0% and from 5% to 0.3%, respectively. ICT positivity prevalence in Pruda and Lewomada decreased from 22.9% and 6.5% to 7% and 0.8%, respectively, whereas BR antibody prevalence in Pruda, Lewomada, and Paga decreased from 28.9%, 31.7%, and 12.5% to 3.6%, 4.1%, and 1.8%, respectively. Logistic regression analysis indicated that that Mf, BR, and ICT prevalence decreased significantly over time and that for the Mf and ICT outcomes the semiannual treatment had higher odds of positivity. Model-adjusted prevalence estimates revealed that apparent differences in treatment effectiveness were driven by differences in baseline prevalence and that adjusted prevalence declined more rapidly in the semiannual treatment group. We conclude that in this setting, annual MDA was sufficient to reduce Mf prevalence to less than 1% in areas with low to moderate baseline prevalence. Semiannual MDA was useful for rapidly reducing Mf prevalence in an area with higher baseline endemicity.

O documento audiovisual é um material que integra a imagem em movimento e o som em sua essência. Constata-se que esse tipo documental está cada vez mais presente nas relações interpessoais e, concomitantemente, nas unidades de informação. O documento audiovisual em foco nesta pesquisa é o filme de ficção. Desse modo, questiona-se: como a Ciência da Informação está tratando a temática desses materiais? Assim, foi feito um levantamento bibliométrico em base de dados com o objetivo de analisar a literatura a respeito dos modos de tratamento temático de filmes de ficção no âmbito da Ciência da Informação e, também, entender como vem ocorrendo o tratamento temático desses materiais. O método é documental e bibliométrico. Como resultados destacam-se a baixa incidência de estudos que abordam a temática; a influência do Cinema enquanto disciplina nos processos de indexação de audiovisual e a presença de um campo vasto para o desenvolvimento de pesquisas.

A Constituição Brasileira, no artigo 207, expõe que as universidades devem obedecer ao princípio de indissociabilidade entre ensino, pesquisa e extensão. (BRASIL, 1988). Assim sendo, a Extensão Universitária denota prática acadêmica que estabeleça uma postura da Universidade na sociedade em que se insere. Seu papel é baseado em um processo interdisciplinar, educativo, cultural, científico e político, por meio do qual se promove uma interação que transforma não apenas a Universidade, mas também os setores sociais com os quais ela interage. Os objetivos desse estudo foram: (1) descrever o trabalho realizado e a experiência adquirida dentro de um projeto de extensão universitária da área de saúde intitulado “Ambulatório de Odontologia Oncológica”, criado no primeiro semestre de 2014; (2) expor a importância do atendimento odontológico promovido pelo referido projeto no Núcleo de Odontologia Hospitalar e na Clínica Médica II do Hospital Universitário da Universidade Federal de Santa Catarina (HU/UFSC). Do ponto de vista de serviço, conclui-se que os atendimentos odontológicos promovidos pelo projeto de extensão Ambulatório de Odontologia Oncológica – Onco-hematologia são essenciais para a atenção integral do paciente oncológico, permite uma atuação interdisciplinar dos profissionais da saúde envolvidos, além da formação técnico-científica adicional que alunos de graduação extensionistas do projeto, podem adquirir.
Avaliação da evolução do índice geral de cursos - IGC das instituições de ensino superior de Santa Catarina

Published: December 2018

A competitividade no setor de ensino faz com que as IES necessitem estar atentas à qualidade do serviço que oferecem, objetivando a manutenção e conquista de novos alunos, parceiros ou investidores. Para muitos alunos, a imagem da instituição e sua qualidade percebida são os principais critérios na escolha de uma IES e isso é transmitido, muitas vezes, através da mídia que publica rankings. Como a maioria dos rankings e indicadores levam em conta o conceito IGC os gestores de IES devem estar atentos a ele, procurando estratégias para melhorá-lo, pois serão os responsáveis por transmitir a qualidade da IES e dos cursos. Desta forma, este trabalho busca avaliar a evolução do IGC nas IES de Santa Catarina no período de 2007 a 2014; avaliando se há diferença na qualidade entre IES públicas e privadas, bem como entre as modalidades de organização acadêmica, a saber, Universidade, Centro Universitário, Faculdade e Instituto Federal, com o intuito de verificar se a divulgação de tais indicadores serve, realmente, como incentivador da melhoria da qualidade das IES, tal como proposto pelo MEC. Através dos dados disponíveis no sistema e-MEC e com o auxílio de testes estatísticos é possível concluir que (1) a evolução do IGC não foi significativa no período analisado; (2) as universidades possuem IGC superior às faculdades em apenas três períodos analisados; (3) as IES públicas possuem IGC superior das IES privadas.

O objetivo do presente estudo descritivo é compreender os significados e as características da gestão para os coordenadores de curso superior de uma universidade federal de Minas Gerais. Para tanto, foram utilizados como base os ensinamentos de Henry Mintzberg (2010). Para a coleta de dados foram realizadas entrevistas semi-estruturadas e para a sistematização dos resultados a técnica análise de conteúdo. Verificou-se que os coordenadores compreendem a gestão de curso superior como o ato de gerenciar o seu projeto pedagógico, como a articulação existente entre os alunos e a administração superior da universidade e como o processo burocrático e de organização que envolve o curso. Dentre as características observadas, ritmo acelerado, no qual as atividades são variadas e desenvolvidas de forma fragmentada. Enfrentam desafios ao lidar com a falta de recursos materiais e humanos e com a falta de uma política de capacitação para o cargo. Também de conciliar as atividades de gestor com as demais atividades da carreira docente, sem que se observe uma política de incentivo. Conclui-se que embora o coordenador esteja gerindo a formação do profissional do futuro, se encontra solto numa estrutura burocrática e política, reagindo às ações e não agindo estrategicamente.

A missão institucional de uma organização, se bem elaborada constitui-se como uma importante ferramenta de apoio à gestão estratégica das instituições. Nesse sentido, o presente trabalho tem como objetivo analisar o status quo da missão institucional das Instituições Federais de Ensino Superior (IFES) brasileiras, a partir dos elementos propostos por Pearce (1982) e Pearce e David (1987). Para tanto a trajetória metodológica adotada divide-se em três partes: Revisão de literatura; Coleta de dados e; análise dos resultados. O estudo assume caráter descritivo com abordagem qualitativa do problema e utilização de fonte secundária de pesquisa. Os resultados evidenciam que, adotados os estudos de Pearce (1982) e Pearce e David (1987), nenhuma das IFES brasileiras possui efetividade integral da missão institucional. Os elementos que foram identificados com maior frequência foram “Referencia ao produto ou serviço” e “Compromisso com o desenvolvimento sustentável (econômico/social/ambiental)”, ao passo que os elementos que se referem a “filosofia e valores da organização” e “imagem da organização” são pouco lembrados nas declarações de missão. Da análise comparativa do status quo da missão das IFES, por região do país, concluí-se que as regiões sul e sudeste concentram as universidades que possuem as missões institucionais mais efetivas e que elementos como referência a corpo funcional e outros stakeholders não são contemplados em nenhuma das instituições.
As fontes de energia e algumas inter-relações CTS concebidas por licenciandos da área de Ciências Naturais
Authors: Ramos Tiago Clarimundo , Fernandes Sobrinho Marcos
Published: December 2018

A ficção do crescimento ilimitado em um planeta finito tem se mostrado insustentável. Nesse sentido, torna-se relevante que sejam acordadas ações conjuntas de controle mais efetivo das atividades econômicas, especialmente para evitar degradação ainda maior da biosfera. É diante dessa problemática e à luz de aportes da educação Ciência-Tecnologia-Sociedade (CTS) que, neste estudo, dispõe-se a responder como licenciandos da área de Ciências Naturais concebem a questão da exploração de diferentes fontes na matriz energética. Em consonância com esse questionamento, objetiva-se analisar os conhecimentos sobre fontes de energia, bem como as inter-relações CTS concebidas por um grupo de 16 sujeitos participantes da pesquisa. Além de identificar certo desconhecimento por parte dos licenciandos em relação à participação das fontes de energia em diferentes matrizes (nacionais e mundiais), com necessidade de esclarecimentos a respeito de determinados fenômenos básicos (como chuva ácida), constatou-se um predomínio de concepções de inter-relações CTS que endossam os mitos da superioridade do modelo de decisões tecnocráticas, da perspectiva salvacionista/redentora atribuída à Ciência e Tecnologia, do determinismo tecnológico e do crescimento econômico ilimitado. Espera-se que este estudo sirva para despertar educadores, sobretudo da área de Ciências Naturais, a fim de minimizarem essas lacunas na formação de professores.

Introduction

The aim of the work was to determine the features of the influence of psychophysiological indices on the result in running for short distances of an elite sportswoman with visual impairments.

Methods

The study involved a high-qualified athlete specializing in short-distance running and long jump. Psychophysiological testing of the athlete took place with appropriate optical lenses. Individual characteristics of the psychophysiological state and results in running at 60 m, 80 m, 100 m, 120 m, 150 m, and 200 m during 5 months of 2015 were analysed. Parameters characteristic for determining the psychophysiological state, typological characteristics of the nervous system, indicators of the nervous system working capacity, and attention indicators were analysed with the help of computer programs for psychophysiological testing. On the basis of the results in running and psychophysiological indicators, a factor analysis was carried out with the main components method with Varimax rotation, and multiple regression analysis by the linear model type in a step-by-step method.

Results

Four factors were identified in the individual structure of psychophysiological functions and effectiveness in running for short distances. Compensatory mechanisms of visual deficiency were identified maintaining high speed in short-distance running as psychophysiological functions, expressed as indicators characteristic of sprinters and specific indicators (efficiency, strength of the nervous system).

Conclusions

On the basis of mathematical models, the strengths of the athlete were highlighted, which tend to develop and also compensate for the inadequacy of the visual analyser.
Radar target simulator with complex-valued delay line modeling based on standard radar components
Authors: Diewald Andreas R. , Steins Manuel , Müller Simon
Published: December 2018

Abstract. With increasing radar activities in the automotive, industrial and private
sector, there is a need to test radar sensors in their environment. A radar
target simulator can help testing radar systems repeatably. In this paper,
the authors present a concept of low-cost hardware for radar target
simulation. The theoretical foundations are derived and analyzed. An
implementation of a demonstrator operating in the 24 GHz ISM band is shown
for which the dynamical range simulation was implemented in a FPGA with fast
sampling ADCs and DACs. By using a FIR filtering approach a fine
discretization of the range could be reached which will furthermore allow an
inherent and automatic Doppler simulation by moving the target.
Modelling confluence dynamics in large sand-bed braided rivers
Authors: Yang Haiyan , Liu Zhenhuan
Published: December 2018

Abstract. Confluences are key morphological nodes in braided rivers where flow converges, creating complex flow patterns and rapid bed deformation. Field survey and laboratory experimental studies have been carried out to investigate the morphodynamic features in individual confluences, but few have investigated the evolution process of confluences in large braided rivers. In the current study a physics-based numerical model was applied to simulate a large lowland braided river dominated by suspended sediment transport, and analyzed the morphologic changes at confluences and their controlling factors. It was found that the confluences in large braided rivers exhibit some dynamic processes and geometric characteristics that are similar to those observed in individual confluences arising from two tributaries. However, they also show some unique characteristics that are result from the influence of the overall braided pattern and especially of neighboring upstream channels.
Velocity response of Petermann Glacier, northwest Greenland, to past and future calving events
Authors: Hill Emily A. , Gudmundsson G. Hilmar , Carr J. Rachel , Stokes Chris R.
Published: December 2018

Abstract. Dynamic ice discharge from outlet glaciers across the Greenland Ice Sheet has
increased since the beginning of the 21st century. Calving from floating ice
tongues that buttress these outlets can accelerate ice flow and discharge of
grounded ice. However, little is known about the dynamic impact of ice tongue
loss in Greenland compared to ice shelf collapse in Antarctica. The rapidly
flowing (∼1000 m a−1) Petermann Glacier in northwest Greenland
has one of the ice sheet's last remaining ice tongues, but it lost
∼50 %–60 % (∼40 km in length) of this tongue via two large
calving events in 2010 and 2012. The glacier showed a limited velocity
response to these calving events, but it is unclear how sensitive it is to
future ice tongue loss. Here, we use an ice flow model (Úa) to assess the
instantaneous velocity response of Petermann Glacier to past and future
calving events. Our results confirm that the glacier was dynamically
insensitive to large calving events in 2010 and 2012 (<10 % annual
acceleration). We then simulate the future loss of similarly sized sections
to the 2012 calving event (∼8 km long) of the ice tongue back to the
grounding line. We conclude that thin, soft sections of the ice tongue
>12 km away from the grounding line provide little frontal buttressing,
and removing them is unlikely to significantly increase ice velocity or
discharge. However, once calving removes ice within 12 km of the grounding
line, loss of these thicker and stiffer sections of ice tongue could perturb
stresses at the grounding line enough to substantially increase inland flow
speeds (∼900 m a−1), grounded ice discharge, and Petermann
Glacier's contribution to global sea level rise.

Tras la revisión de los referentes teóricos que existen para el abordaje arteterapéutico con familias, este trabajo parte de una investigación en la que se han analizado los resultados de 3 años de trabajo de campo en esta área, logrando identificar diferentes elementos de la intervención clínica y del setting en Arteterapia Familiar. El objetivo del presente trabajo es ofrecer una propuesta teórica acerca de los aspectos contratrasferenciales y vinculares en el trabajo arteterapéutico y sus implicaciones en la intervención familiar. Para lograr dicho objetivo se han integrado dos paradigmas: el vínculo triangular arteterapéutico con una perspectiva psicodinámica y las relaciones familiares desde los fundamentos de la terapia sistémica. En lo referente a la intervención con familias, se ha diseñado un modelo teórico que permite adaptar los objetivos terapéuticos a las necesidades específicas de cada caso. Esta propuesta metodológica tiene como finalidad principal que los miembros puedan explorar nuevos sistemas de relación y de colaboración más funcionales a través del proceso creativo compartido, además de desarrollar su expresión emocional utilizando el lenguaje visual como una vía de comunicación intrafamiliar.
Vulnerabilidad, ruptura social y arteterapia
Authors: Mayo Eva
Published: December 2018

Desde la vulnerabilidad social hasta la exclusión social la persona hace frente a un proceso de continuas rupturas y problemáticas difíciles, cuando no imposibles, de superar en soledad. Ante la pérdida del vinculo social y familiar, soporte emocional y factor de protección fundamental para sobrellevar la desventaja social, una intervención social capacitadora y reparadora es esencial. Con este artículo, se realiza una aproximación a las oportunidades que ofrece el arteterapia en el ámbito social para una intervención preventiva, en el marco de la tendencia de trabajo interdisciplinar que se viene siguiendo en el contexto de los servicios sociales. De la confluencia de los objetivos propios de la intervención social y el arteterapia, encontramos estrategias que mejoran la vida de las personas. Les proporcionan bienestar y les facilitan movilizar los recursos propios para el afrontamiento de las rupturas, que en sus distintas dimensiones, personal, social, económico y cultural, resultan ser experiencias traumáticas que se suceden en sus trayectorias vitales.
"Beyond control". Una investigación sobre procesos de creación cinematográfica participativa con menores migrantes no acompañados en Sicilia
Authors: Digrandi Chiara
Published: December 2018

El artículo muestra los resultados de la investigación "Beyond control" que indaga cómo procesos de creación cinematográfica participativa pueden ser un instrumento de expresión para un grupo de menores migrantes no acompañados que han vivido experiencias traumáticas. La experiencia ha sido desarrollada en la Casa de la Cultura de Scicli (Ragusa, Italia). El objetivo de la investigación ha sido explorar cómo los participantes se expresan a través la creación colectiva de películas y qué impacto tiene este proceso en ellos. Los resultados son tres películas: "The surviving migrants", "My mistake" y "Jealous love", realizadas por un grupo de chicos, un grupo de chicas y un grupo mixto. A través de procesos de creación cinematográfica participativa, los participantes han adquirido una especie de "dirección" sobre eventos y situaciones "fuera de control" que pertenecen a su pasado, presente y futuro; usando el poder de las imágenes, han expresado temas relacionados con sus historias de vida. La creación de las películas ha sido una oportunidad para contarse, para sentirse capaces y ganar confianza en sí mismos, para "ser vistos" y sentirse reconocidos por una comunidad más amplia contribuyendo, de tal forma, a la curación de los traumas vividos.
Digital technologies and Social Relations of Age, Gender and Class among Seniors: An Intersectional Approach
Authors: Bourdeloie Hélène
Published: December 2018

A good deal of research uses the sociology of domination to study inequalities in digital technology usage as these often stem from deep-cut social divides. Bourdieu’s theory of domination has been widely employed to demonstrate that the social world is stratified according to a principle of legitimacy: the social hierarchy holds good because those who are dominated do not challenge this order. Yet, in the digital era – which is a destabilising factor for traditional hierarchies – this type of theory comes up against certain limits due to its static premises. For this reason, our study adopted an intersectional approach, as this is more able to take into account the power relations between individuals and, more specifically, the forms of resistance that drive individuals. A field study conducted with French people over the age of 60 served as the basis for this theoretical analysis. The study shows that the seniors’ differentiated relationships with ICTs correlate strongly with their age group, gender and class. When these analytical categories are combined, patterns emerge – patterns that are not only specific but which also reflect a process of negotiation with the dominant norms.
On Malaysian House Price Growth: The Effects of Market Sentiments
Authors: Cheong Calvin W. H. , Ngui Lisa L. H. , Beatrice Shella Georgina
Published: December 2018

This paper examines the factors that drive the recent exponential growth in Malaysian house prices. We first construct a sentiment index for the housing market in Malaysia guided by the methods employed by Baker and Wurgler (2006). Preliminary analyses of our bias-free sentiment index indicate a strong correlation with overall market confidence which attests to the reliability of our index. The results also show contemporaneous sentiment to strongly influence future housing market returns especially in the short-term. Contrary to the literature, our results suggest that it is property developer behaviour that drive sentiments and property prices. The study contributes to the literature by providing an easily generalizable method of constructing a housing market sentiment index in other countries that holistically accounts for essential housing market elements that are otherwise ignored in confidence indices. This study also contributes to practice as it provides evidence to policy-makers who wish to cool property markets may want to design interventions that are targeted at property developers instead of home-buyers or speculators.

Na paciente em questão, foi realizado o manejo cirúrgico da fratura com auxílio de miniplacas e parafusos do sistema 2.0mm em um acesso intraoral. No acompanhamento pós-operatório observou-se material de osteossíntese e odontossíntese em posição, fratura adequadamente reduzida e ausência de sinais de deslocamento dos cotos fraturados. Considerações finais: o uso do sistema de fixação interna rígida está indicado em casos de fraturas desfavoráveis de mandíbula uma vez que apresenta resultados satisfatórios referentes a estabilização e cicatrização óssea. A redução e fixação com auxílio de miniplacas e parafusos tendem a evitar o deslocamento dos cotos fraturados e formação de pseudoartrose.

Published: December 2018

Objetivo: relatar o caso de um paciente idoso portador de defeito ósseo de Stafne. Relato de caso: paciente dosexo masculino, 74 anos de idade, foi atendido na Clínica de Odontologia da União Metropolitana de Educaçãoe Cultura, e, após realização de radiografia panorâmica, foi evidenciada uma imagem sugestiva do defeito,sendo o paciente orientado a realizar a tomografia computadorizada fan beam para a confirmação diagnóstica.Considerações finais: o defeito ósseo de Stafne é definido como uma depressão lingual na mandíbula,de forma arredondada ou ovoide, que varia de 1 a 3 cm em diâmetro, com margens ósseas muito densas e bem definidas. Apresenta-se, radiograficamente, como uma imagem radiolúcida, circunscrita e unilocular na região posterior da mandíbula, abaixo do canal mandibular. É geralmente detectado em exames radiográficos de rotina, como a radiografia panorâmica, e a confirmação do diagnóstico geralmente é obtida pela realização da tomografia computadorizada fan beam ou de cone beam, por conta da obtenção de imagens que possibilitam a avaliação tridimensional, descartando, assim, outros tipos de lesões. Por se tratar de uma variação anatômica, a conduta é proservar o caso.
High School Students’ Perceptions of Nontraditional Music Classes
Authors: Kelly Steven Nelson , Veronee Kenna
Published: December 2018

This examination was an investigation of high school music students’ perceptions of nontraditional music classes. The specific questions were: (a) What nontraditional music courses were offered at participants’ schools?; (b) What were the participants’ perceived values of specific nontraditional music courses?; and (c) In which nontraditional music courses would participants enroll if offered at their schools? Findings showed participants would take nontraditional music courses if they were offered and perceived these courses as having musical value. However, curricular offerings selected most and perceived as having the highest value appeared to be common, perhaps more familiar, courses (e.g., music theory). As reported in the study, courses offered most frequently included Advanced Placement Music Theory, Music Theater, and Piano/Keyboard. Participants gave the highest values to Music Theory, Advanced Placement Music Theory, and Music Composition/Arranging. Courses participants indicated they would enroll in most were Music Composition/Arranging, Advanced Placement Music Theory, and Music Theory.

Nurses play significant roles in health promotion and health education about healthy lifestyle practices and are considered role models of healthy lifestyle behaviours. It is unclear if their knowledge of healthy lifestyle choices translate to practice. This study assessed the lifestyle behaviours of primary healthcare professional nurses in the Eastern Cape Province, South Africa. This descriptive, cross-sectional study involved 203 purposively selected primary healthcare nurses in Eastern Cape Province, South Africa. We utilised the WHO STEPwise questionnaire to assess the lifestyle behaviour (smoking, alcohol use and physical activity) of the nurses. Descriptive and inferential statistics were carried out at a significance level of p<0.05. The participants’ mean age was 45.17 (Standard Deviation±11.26) years. Of all the participants, 27% had ever taken alcohol, and 18% currently use alcohol. Only 8% had ever smoked and of these, 3% currently smoke. Of all the participants, 33% do not engage in physical activities, and only 29% of them met the WHO recommendation for being active. Most of them were aware of the benefits of physical activities. Majority of the participants cited lack of time (74%) and lack of commitment (63%) as barriers to physical activity and few of them cited health challenges (3.9%). Among the primary health care professional nurses in this setting, we found a high prevalence of alcohol use and low prevalence of smoking and physical activity among primary health care nurses in this setting. There is a need to implement effective workplace strategies and wellness programmes that will foster healthy lifestyle practices among the nurses.
Fiscal Policy Tools and Economic Growth in Jordan: Evidence from Time-Series Models
Authors: Mugableh Mohamed Ibrahim
Published: December 2018

This paper examines equilibrium relationships and dynamic causality analyses between economic growth and fiscal policy tools in Jordan for the (1978-2017) period. It employs autoregressive distributed lag and vector error correction models. The results suggest that there is evidence of a co-integration and causal relationships between economic growth and fiscal policy instruments. General government expenditures have long-run positive impact on economic growth, implying that general government expenditures improve economic growth. Moreover, total tax rates have long-run negative impact on economic growth, implying that a tax cut stimulates economic growth. These results are broadly consistent with similar studies carried out for other developing economies. 
A Business Failure Index Using Rank Transformation
Authors: Restaino Marialuisa , Bisogno Marco
Published: December 2018

The global financial crisis entails a renewed attention from financial institutions, academics, and practitioners to corporate distress analysis and its forecasting. This study aims to propose a model for predicting default risk based on a business failure index using rank transformation. The procedure suggested is able to capture firms’ financial difficulties and forecast bankruptcy through the construction of a failure index based on some relevant financial ratios. By means of the estimation of failure probability, it allows to classify and predict business distress in time to take mitigating action. This procedure is evaluated by some accuracy measures on a sample of Italian manufacturing firms, and is found to be a suitable instrument for preventing financial distress.
Notes on the evolution of the ammonite families Aulacostephanidae and Cardioceratidae and the stratigraphy of the uppermost Oxfordian and lowermost Kimmeridgian in the Staffin Bay sections (Isle of Skye, Northern Scotland)
Authors: WIERZBOWSKI Andrzej , MATYJA Bronisław A. , WRIGHT John
Published: December 2018

Detailed study of all the ammonite collections gathered by the authors in the Staffin Bay sections has resulted in minor changes
in the distribution of ammonite taxa, and slight modification of the position of the Oxfordian/Kimmeridgian boundary. Most significant is
the discovery of Pictonia (Triozites) cf. seminudata which results in the placing of the stage boundary 0.16 m below the level formerly
proposed. This study discusses the evolution of the Subboreal family Aulacostephanidae, and the Boreal family Cardioceratidae, indicating
changes in the patterns of individual development in the evolution of both families in terms of heterochrony. The Oxfordian/
Kimmeridgian boundary interval shows major morphological changes in both ammonite families which were released from phylogenetic
constraints by heterochrony, closely related to changes in environmental conditions.
Dinoflagellate cyst assemblages across the Oxfordian/Kimmeridgian boundary (Upper Jurassic) at Flodigarry, Staffin Bay, Isle of Skye, Scotland – a proposed GSSP for the base of the Kimmeridgian
Authors: BARSKI Marcin
Published: December 2018

Examination of seven ammonite-calibrated palynological samples across the Oxfordian/Kimmeridgian boundary in the Flodigarry sections at Staffin Bay, Isle of Skye, northern Scotland, has revealed dinoflagellate cyst assemblages in general terms in line with previous contributions. The sparse occurrence of Emmetrocysta sarjeantii, Perisseiasphaeridium pannosum and Senoniasphaera jurassica slightly above the proposed Oxfordian/Kimmeridgian boundary may be used as a palynological approximation of the base of the Kimmeridgian. The high abundance of tests resembling modern zygnemataceous chlorophycean alga Spirogyra in two samples above the Oxfordian/Kimmeridgian boundary horizon is probably associated with increased eutrophication and possible association with ‟green tides”. This bloom is proposed as a palynofloral proxy event for the boundary in the Flodigarry section. According to previous studies, various eutrophication events may have a correlation potential in Subboreal Europe.
Silent sinus syndrome associated with natural childbirth
Authors: Sobolewska Aleksandra , Clarós Pedro
Published: December 2018

Spontaneous, painless enophthalmos, hypoglobus with orbital floor resorption and maxillary sinus collapse on the ipsilateral side is recognised as a rare condition known as the silent sinus syndrome. This paper aimed to present an unusual association of natural childbirth and the onset of orbital floor displacement caused by silent sinus syndrome. We wanted to present a case of a 31-year-old woman presented with a 3-month history of painless, progressive right enophthalmos otherwise utterly asymptomatic who developed symptoms shortly after natural childbirth. That association have never been presented before in literature. We also wanted to discuss the pregnancy-related nasal congestion. We present our experience with these case treated with a single-stage procedure, focusing on the advantages of this one-step approach.

Published: December 2018

Inflammation of the periapical tissue may lead to the development of complications involving cooperation between many medical specialists. The cutaneous fistula is a rare complication of chronic alveolus inflammation being diagnostic and therapeutic challenge due to unspecific symptoms. The correct diagnostic protocol may influence correct diagnosis, localization of the primary site of inflammation and the appropriate treatment.
