The Potential Role of the Software Industry in Supporting Economic Development
Authors: Kamel Sherif H.
Published: October 2018

Emerging information technologies provide a solid and promising platform to support economic development. In that respect, the information and communication technology sector has been one of Egypt's strongest economic sectors with increasing prospects for job creation, productivity, scalability, impact, and growth. One of the subsets of ICT, the software industry, is gradually becoming more visible, stronger, and mature in terms of output and impact both locally and beyond. Software is arguably the best entry platform for developing nations, like Egypt, into the global ICT production complex. Local companies and startups in the software development space have started their operations over the last decade trying to capture a segment of the regional and global market opportunities. This chapter assesses the developments in the software industry in Egypt and the potential role it can play as a contributor to economic development through the establishment of an export-oriented outsourcing software industry capitalizing on one of Egypt's primary resources, human capital.
Reconstructive Architectural and Urban Digital Modelling
Authors: Spallone Roberta
Published: October 2018

The digital reconstruction of architectural and urban complexes, which were demolished, transformed, or have been only theoretically conceived, remaining “on paper,” is now a tool of considerable heuristic value, allowing to preserve, interpret, and create new images of cultural heritages that no longer exist in their original shape or never reached a material construction. The tools, methods, and techniques of representation (graphical analysis, two and three-dimensional modeling, animation, prototyping) should be carefully chosen, case by case, in order to interpret properly the basic data and create original interpretations, using as research sources and ideas not only the archival drawings and any surviving vestiges but also the autobiographical writings and the more inspired analysis developed by the architecture critics. The examination of several international case studies and also some experiences personally conducted highlights the different strategies used for the preservation of the memory of such heritage.
Local Search Strategy Embedded ABC and Its Application in Cost Optimization Model of Project Time Schedule
Authors: Sharma Tarun K. , Rajpurohit Jitendra
Published: October 2018

This article describes how artificial bee colony (ABC) is a promising metaheuristic algorithm, modeled on the intelligent forging behavior of honey bees. ABC takes its inspiration from natural honey bees. In ABC the colony of bees is generally alienated into three groups namely scout, employed and onlooker bees that participates in getting optimal food sources (solutions). With an edge over similar metaheuristic algorithms in solving optimization problems ABC suffers with bad exploitation (local search) capability, however excels in exploration (global search) capability. In order to balance both the aforesaid capabilities, this article embeds the local search strategy in the basic structure of ABC. The proposed scheme is named as LS-ABC. The efficiency of the proposed scheme has been tested and simulated results are compared with state-of-art algorithms over 12 benchmark functions. Also, LS-ABC has been validated to solve cost optimization model of project time schedule. The simulated results are compared with state-of-art algorithms.
Using Experiential Client-Based Projects in Sport Sales Courses
Authors: Pierce David
Published: October 2018

Sales has gradually gained traction in the sport management programs over the past 15 years. This article examines the extent to which client-based experiential projects are used in sport sales courses and determines if teaching practices are different in client-based and non-client-based courses. Online survey responses were received from 36 of 85 sport management programs that offer a sport sales course. Results indicated that 58.3% of sport sales courses utilized a client-based experiential sales project. The sports properties that partner with sales classes the most are college athletics, minor league teams, and Big Five professional sports teams. Clients provided students with leads in 55% of the projects. The most popular organizational model was the independent model, which was employed by 70% of the courses engaging in a client-based project, followed by the on-campus and in-venues models. Client-based courses were more likely to use mock sales calls, guest speakers, and the Sales Huddle game. Implications for teaching client-based experiential courses are addressed.

B Cell–Intrinsic STING Signaling Triggers Cell Activation, Synergizes with B Cell Receptor Signals, and Promotes Antibody Responses
Authors: Walker Melissa M. , Crute Bergren W. , Cambier John C. , Getahun Andrew
Published: October 2018

Generation of protective immune responses requires coordinated stimulation of innate and adaptive immune responses. An important mediator of innate immunity is stimulator of IFN genes (STING, MPYS, MITA), a ubiquitously but differentially expressed adaptor molecule that functions in the relay of signals initiated by sensing of cytosolic DNA and bacterial cyclic dinucleotides (CDNs). Whereas systemic expression of STING is required for CDN-aided mucosal Ab responses, its function in B cells in particular is unclear. In this study, we show that B cells can be directly activated by CDNs in a STING-dependent manner in vitro and in vivo. Direct activation of B cells by CDNs results in upregulation of costimulatory molecules and cytokine production and this can be accompanied by caspase-dependent cell death. CDN-induced cytokine production by B cells and other cell types also contributes to activation and immune responses. Type I IFN is primarily responsible for this indirect stimulation although other cytokines may contribute. BCR and STING signaling pathways act synergistically to promote Ab responses independent of type I IFN. B cell expression of STING is required for optimal in vivo IgG and mucosal IgA Ab responses induced by T cell–dependent Ags and cyclic-di-GMP but plays no discernable role in Ab responses in which alum is used as an adjuvant. Thus, STING functions autonomously in B cells responding to CDNs, and its activation synergizes with Ag receptor signals to promote B cell activation.

Low-dose IL-2 represents an immunotherapy to selectively expand regulatory T cells (Tregs) to promote tolerance in patients with autoimmunity. In this article, we show that a fusion protein (FP) of mouse IL-2 and mouse IL-2Rα (CD25), joined by a noncleavable linker, has greater in vivo efficacy than rIL-2 at Treg expansion and control of autoimmunity. Biochemical and functional studies support a model in which IL-2 interacts with CD25 in the context of this FP in trans to form inactive head-to-tail dimers that slowly dissociate into an active monomer. In vitro, IL-2/CD25 has low sp. act. However, in vivo IL-2/CD25 is long lived to persistently and selectively stimulate Tregs. In female NOD mice, IL-2/CD25 administration increased Tregs within the pancreas and reduced the instance of spontaneous diabetes. Thus, IL-2/CD25 represents a distinct class of IL-2 FPs with the potential for clinical development for use in autoimmunity or other disorders of an overactive immune response.
Effect of adhesive mode and chlorhexidine on microtensile strength of universal bonding agent to sound and caries-affected dentins
Authors: Lima Joyce Figueiredo Macedo de , Wajngarten Danielle , Islam Fariya , Clifford Johanna , Botta Ana Carolina
Published: October 2018

Objective: The main objective of this study is to assess the effect of the adhesive mode and chlorhexidine (CHX) on the microtensile strength of a universal bonding agent to sound and caries-affected dentins. Materials and Methods: Six intact third molars and six decayed third molars were sectioned to obtain two middle dentin specimens per tooth. Prime and Bond Elect Universal (Dentsply) was applied to specimens in two different modes: Etch-and-rinse (ER, phosphoric acid for 15s) and self-etch (SE, no phosphoric acid). 2% CHX (Cavity Cleanser, Bisco) was applied to both dentins for 30 s. Specimens were randomly assigned into eight groups (n = 3) according to the treatments applied to sound and caries-affected dentins: SE; ER; SE + CHX; and ER + CHX. All specimens were restored with TPH Spectra High Viscosity (Dentsply) composite resin and sectioned to obtain specimens of 0.8 ± 0.1 mm2. The microtensile bond strength test was conducted at 1 mm/min. The data were statistically analyzed by ANOVA and multiple comparisons' test (α = 0.05). Results: There was no significant difference between sound dentin and caries-affected dentin (P = 0.132). The highest bond strength was obtained with the application of the ER (31.81MPa). SE + CHX promoted the lowest bond strength with no statistical difference to ER + CHX (P > 0.05). Conclusions: ER mode for the universal bonding agent yielded the highest bond strength to sound and caries-affected dentins. CHX reduced the bond strength to both dentins regardless the application of phosphoric acid. Clinical Significance: The universal bonding agent increased the bond strength to sound and caries-affected dentins when applied by the ER mode.
Precise geometry of the anterior chamber of the eye by means of OCT imaging.

Published: October 2018

Nowadays medicine highly relies on non-invasive optical diagnostic methods. The likewise situation is in the case of ophthalmology, especially in diagnosis of anterior segment eye diseases, where optical coherence tomography (OCT) plays inestimable role. OCT devices can do fast, painless measurements of the anterior segment of the eye. Nonetheless it should be remembered that the OCT images are burdened with an optical distortion and they doesn’t reflect the true geometry of the eye. This study presents an algorithm for correcting the distortion in OCT images and reflecting true parameters of the anterior segment of the eye. Full Text: PDF ReferencesA. Podoleanu, I.

Critical success factors influencing performance outcome of joint venture construction projects in South Africa: Comparison of first and second order models
Authors: Mba Marie Francoise Bekale , Agumba Justus Ngala
Published: October 2018

Joint ventures (JVs) have become increasingly common, because of the complexity and challenges associated with the delivery of construction projects globally and in South Africa. However, it has been established that JV projects have experienced unsatisfactory performance leading to clients’ dissatisfaction. The purpose of this paper is therefore to determine the critical success factors (CSFs) influencing the performance of JV construction projects in South Africa. A positivist philosophy position was adopted using a structured questionnaire survey administered to the construction professionals. Prior to the main study, a content validity of the questionnaire was achieved using a pilot study. The data was collected from 115 conveniently sampled respondents, and analysed using principal component analysis and multiple regression analysis. The exploratory factor analysis revealed two empirical models to be tested; namely the first and second order factor models. The result of the first order model revealed that, management control influenced achievement of project objective of JV, whereas, the second order model established that understanding of contractual agreement, which was explained by six components of CSFs influenced achievement of project objective. It is suggested that stakeholders who prefer to be involved in JV projects should acquire good understanding of the contractual agreement in managing JV projects in order to successfully achieve the project objectives. This study adds to the discourse and literature on CSFs of JVs. It provides new empirical evidence of the CSFs that influence project performance outcome of JV in the context of South Africa which can also be replicated in other countries globally. However, the study may not be generalised because of the geographical setting and respondents.
Work practices of onsite construction crews and their influence on productivity
Authors: Loganathan Santhosh , Forsythe Perry , Kalidindi Satyanarayana N
Published: October 2018

The nature of construction work processes allow crews and workers to follow their own practices in how they plan, organise and coordinate work. However, there is little research into the nature of crew work practices. This paper aims to unveil the influence of onsite crew work practices on productivity. An exploratory case study investigated work practices on a residential project involving two separate crews (of 18 and 23 workers) engaged in rebar placement for 112 columns each, which included a high-performing and an average-performing crew. A triangulated mixed methods approach to data gathering utilised site observations, individual and group interviews, and time measured work studies, to assess productivity of the crews. The findings indicate that the high-performing crew achieved 44% higher productivity than the average-performing crew and this manifested across specific tasks including rebar cutting, bending, stirrup fabrication and tieing. Five broad work practices were observed to significantly influence the above productivity differences: work preparation and execution strategy; group formation and stability; avoiding duplication of tasks; crew social cohesion; and internal and external leadership practices. These five practices are proposed as dimensions that can be used to measure crew productivity in ongoing research. In-depth understanding of crew based work practices will enable training of foremen and work crews in such practices to systematically develop high-performing crews.
Autoethnography and Theory Testing
Authors: Livesey Peter Vincent , Runeson Goran
Published: October 2018

One of the problems in construction management research is how to harvest the living experience of people working in the profession. Surveys and interviews are the common methods, but they have obvious problems, not only with defining terminology and targeting the appropriate populations but also with the knowledge of the respondents and their willingness to reflect. Autoethnography, in its conventional form, overcomes most of these problems, but creates a new set of problems, particularly in terms of our ability to generalise and verify the results. What is argued here is that autoethnography can be applied analytically and rigorously so that it can be used for theory testing and theory building. The approach is illustrated by a case study, in which professional experience in the construction industry is integrated into the conventional scientific method.

La música como modelo de inclusión social en espacios educativos con alumnado gitano e inmigrante
Authors: Aparicio Gervás Jesús María , León Guerrero María Montserrat
Published: October 2018

Violencia, racismo, xenofobia y absentismo escolar, son algunos de los prejuicios y estereotipos que aparecen entre el alumnado de numerosos centros educativos ubicados en zonas urbanas marginales con mayoría de población inmigrante y gitana. La investigación tiene como objetivo el desarrollo y aplicación de un proyecto de educación intercultural sustentado en la formación musical y avalado por diferentes experiencias realizadas en contextos de similares características. Partimos de la hipótesis de que la formación musical incide muy positivamente en la génesis de actitudes y valores de respeto y tolerancia, como así ha ocurrido en las experiencias aplicadas en Venezuela, Estados Unidos, Reino Unido, Brasil, por poner algunos ejemplos. Metodológicamente se plantea desde una perspectiva cualitativa utilizando el método etnográfico y las técnicas de la entrevista en profundidad y la observación participante. La experiencia ha generado la reducción del absentismo escolar, la superación de prejuicios y estereotipos y ha permitido la construcción de espacios comunes de convivencia e inclusión escolar, favoreciendo complementariamente el éxito escolar de este tipo de alumnado.
Desarrollo de una escala de actitudes hacia el bienestar animal para estudiantes de Educación Primaria
Authors: Mazas Gil Beatriz , Fernández Manzanal Rosario
Published: October 2018

El significado de bienestar animal está adquiriendo gran difusión en nuestra sociedad. En este trabajo hemos desarrollado y validado una escala de actitud hacia el bienestar animal que contempla aspectos como el maltrato de los animales por placer o por desconocimiento, el empleo de animales para el ocio, las situaciones en las que se hallan los animales de granja o el abandono de mascotas. Con este instrumento se ha medido la actitud entre los estudiantes de Primaria y se han obtenido resultados que animan a incluir algunos contenidos relacionados con el bienestar de los animales en las clases de ciencias. De entre las conclusiones más relevantes de esta exploración podemos extraer que a medida que aumentan los cursos, la actitud hacia el bienestar animal es poco a poco más desfavorable, y también que la actitud menos favorable hacia el bienestar animal siempre surge en el componente 2, que trata sobre el ocio con animales. Palabras clave: Bienestar animal, escala de actitudes, estudiantes, Educación Primaria

Authors: Vílchez Mª Pilar , Sánchez-Romero Elisa Isabel , Reche Cristina , De Francisco Cristina
Published: October 2018

En este trabajo se presenta un programa para el desarrollo moral en personas con discapacidad intelectual a través de actividades predeportivas realizadas en un contexto educativo dirigido a su inserción sociolaboral. El programa diseñado se basa en la teoría del desarrollo moral de Kohlberg con el fin de aumentar la competencia moral del alumnado trabajando distintos valores combinando tareas motrices con la discusión de dilemas morales en actividades deportivas. Participaron 23 estudiantes (11 hombres y 12 mujeres) con edades comprendidas entre los 21 y los 31 años (M=25.96; D.T.=3.15) en un diseño pretest-postest con grupo de control. El sistema de evaluación utilizado fue la adaptación al español para discapacidad intelectual del Test de Competencia Moral (MCT). El grupo que recibe el programa de predeporte y desarrollo de valores reflejó un aumento en la competencia moral, aunque no llegó a ser estadísticamente significativa. Los resultados alientan a seguir investigando en esta línea en pro del desarrollo moral y condición física de estas personas.
Ignorancia inconsciente en las representaciones de la investigación durante el proceso de titulación universitaria
Authors: Veintimilla Gregory , Fontaines-Ruiz Tomas , Tusa Jumbo Fernanda
Published: October 2018

El objetivo del estudio fue analizar las representaciones sociales de la investigación que tienen los estudiantes universitarios matriculados en el proceso de titulación en la Universidad Técnica de Machala con la finalidad de detectar los sentidos errados que testimonien el desconocimiento aprendido. La metódica de investigación fue cualitativa. Se trabajó con 140 estudiantes matriculados en el proceso de titulación de la precitada universidad, de los cuales el 40% eran del sexo femenino y el 60% masculino. La distribución por unidades académicas fue la siguiente: 36% pertenece a ciencias empresariales, 50% a ciencias sociales, 8% ingeniería civil, 4% ciencias agropecuarias y el 2% a ciencias químicas y de la salud. La selección fue a través de un muestreo opinático intencional. Se aplicó un cuestionario sobre representaciones de la investigación, mediante formulario digital. Como estrategia de validez se empleó la triangulación de investigadores y la devolución de los hallazgos a los informantes. Se identificó que la ignorancia inconsciente está enraizada en la normatividad metodológica como condicionante ontológico y gnoseológico de la investigación, develándose como síntomas los siguientes: asepsia ideológica de la investigación, Reduccionismo del saber y negación de lo múltiple, transferencia acrítica del método, el experto como actor de la investigación. Se concluyó la conformación de la ignorancia inconsciente nace de la adopción y legitimación acrítica del método, que sostiene que investigar es una consecuencia del método y de la presencia de sus actores, hecho que contradice la noción constructiva, ideológica e interaccional de la investigación. La rigidez de estos conceptos, hace que el objeto de estudio sea forzado a entrar en el canon metódico como garantía de cientificidad.
Inversión educativa y contracción del Estado del Bienestar: un análisis del contexto autonómico tras la crisis sistémica de 2008
Authors: Sánchez Villar Juan Mª
Published: October 2018

En España, el estallido de la crisis sistémica de 2008 y su prolongada duración han supuesto desafíos adicionales para el mantenimiento del Estado del Bienestar y, particularmente, para la educación, el Servicio Público Fundamental que más afectado se ha visto por la aplicación de políticas de contracción presupuestaria durante este período. El presente trabajo explora cómo se ha comportado la inversión educativa en las distintas regiones españolas a lo largo de los últimos años, y trata de conocer más acerca del papel que han jugado las distintas administraciones en la asignación de recursos a esta partida. Para ello, esta investigación ha conformado dos bloques de CC.AA. de acuerdo con la incidencia económica de la crisis y ha efectuado un análisis longitudinal y comparativo a partir de diversos indicadores. Los resultados revelan que la voluntad política ha sido fundamental a la hora de determinar las pautas de inversión educativa y que, además, las diferencias entre distintos colores políticos son reducidas. Las implicaciones de estos resultados abren la puerta a una interpretación más amplia acerca de la importancia y necesidad de redefinición de la educación como vector de generación de capital social en España, así como a un debate político más profundo sobre su financiación en el marco del actual Estado del Bienestar.
Análisis de "serious games" anti-"bullying": recursos lúdicos para promover habilidades prosociales en escolares
Authors: Del Moral Pérez María Esther , Villalustre Martínez Lourdes
Published: October 2018

La investigación se adscribe al Personal and Social Learning & Ethics (PSLE) que propugna la implementación de serious games (SG) para fomentar aprendizajes personales y sociales desde una perspectiva ética. Estudia la potencialidad educativa de una muestra de SG anti-bullying online gratuitos (N=10) —promovidos por instituciones educativas internacionales—, orientados a desarrollar habilidades prosociales en escolares. Para ello, se utiliza una metodología cualitativa centrada en el análisis de contenido que sirve para identificar las estrategias que adoptan: 1) aspectos psico-lúdicos e interactivos que priman (tipología de agresiones expuestas, teoría del aprendizaje subyacente y estrategias lúdicas adoptadas); y, 2) grado en que promueven distintas habilidades (analíticas, metacognitivas y prosociales). Así, se constata que la mayoría de estos juegos recrea simulaciones de agresiones verbales y físicas a víctimas y daños a sus pertenencias, ciberbullying, amenazas, chantajes, humillaciones, etc., invitando al jugador a asumir roles para identificarse con la víctima o con amigos de ésta, y a protagonizar situaciones críticas. Sus mecánicas de juego ayudan a: discriminar actitudes y conductas negativas, reconocer los sentimientos propios y ajenos, favorecer la empatía para conectar con otros, tomar decisiones y resolver conflictos asertivamente. Sin embargo, adolecen de dinámicas que estimulen la comunicación (capacidad negociadora, escucha activa y asertividad). Este trabajo ofrece a los docentes de primaria 10 atractivas aplicaciones interactivas de carácter lúdico —simuladores o juegos de rol— que pueden integrarse como recursos didácticos en programas preventivos del maltrato entre iguales. Si bien requieren diseñar actividades que activen de forma complementaria habilidades ligadas a la comunicación interpersonal, e inviten al alumnado explícitamente a la reflexión y análisis crítico de sus actos, para favorecer el respeto y el entendimiento mutuo. También se presenta un instrumento para sistematizar el análisis de contenido y potencial didáctico de serious games anti-bullying.

Objetivou-se comparar o grau de incapacidade física, os sítios corporais afetados, as deficiências e incapacidades presentes e os nervos acometidos no diagnóstico e na alta em pacientes com hanseníase.  Trata-se de um estudo desenvolvido entre 2009 e 2014 em centro de referência para hanseníase na Paraíba. Envolveu 414 prontuários, utilizando formulário estruturado. Os dados foram analisados através de técnicas de estatística descritiva (frequência absoluta e percentagem) e inferencial (Teste de Wilcoxon e Mcnemar). Nota-se decréscimo do acometimento dos sítios corporais (nariz p=0,000), das deficiências (ressecamento p=0,002 e ferida p=0,000 no nariz e úlcera p=0,004 nos pés) e da quantidade de nervos afetados (p=0,000) entre o diagnóstico e a alta por cura. Na análise dos anos 2009-2014 observa-se redução da quantidade de pacientes apresentando grau de incapacidade física 2. Conclui-se, portanto, que mesmo após a alta os pacientes estão propícios a desenvolver ou agravar incapacidades físicas, necessitando de acompanhamento periódico.
Tot (aan) het einde ((aan) toe): The internal syntax of a Dutch complex PP
Authors: Broekhuis Hans , den Dikken Marcel
Published: October 2018

The topic of this paper is the internal syntax of the extraordinarily rich palette of Dutch expressions corresponding to English (right) up to the end, featuring six subtly different surface outputs, differing with respect to the number of adpositional elements, the number of occurrences of a particular adpositional element (“doubling”), and the linear order of the various subconstituents of the complex PP. The paper proposes a maximally integrated syntax for these adpositional phrases, and in the process addresses the details of phrasal and head-movement operations taking place within the complex PP. In closing, the paper briefly examines the properties of the antonym of (right) up to the end, viz., (right) from the beginning (on), and signals clear similarities and striking differences between the two.

Objetivou-se com esse trabalho avaliar as alterações microbiológicas e físicas da carne bovina inoculada com a bactéria Escherichia coli sob a ação de ácidos orgânicos como agentes sanitizantes. O experimento foi em esquema fatorial 3X3, sendo três tratamentos e três períodos de avaliação. Os tratamentos foram: Tratamento 1: controle (utilização de água destilada para sanitização superficial da carne), Tratamento 2: aplicação por spray, de solução de 1,0 % de ácido lático e Tratamento 3: aplicação por spray, de solução contendo 1,0 % de ácido acético. As amostras foram submetidas às avaliações de contagem de total de aeróbios mesófilos, coliformes e físico-quimicamente, nos tempos 0, 7 e 14 dias de estocagem sob refrigeração. Em relação às características físico-químicas, não foram observadas diferenças significativas (P>0,05) para as interações entre os tratamentos e os tempos. Aos 14 dias de armazenamento, as amostras apresentavam menores valores Aa e CRA e maiores contagens de coliformes (P<0,05). A utilização de ácido lático foi eficiente na redução da contagem de aeróbios mesófilos (P<0,05). Para pH, a utilização de ácido acético resultou em menores valores de pH aos 14 dias. Para cor, as amostras tratadas com ácido lático estavam mais claras e a utilização de ácido acético propiciou menor escurecimento (P<0,05). A utilização de ácidos orgânicos foi eficiente na redução da contagem total bacteriana o que pode ter propiciado menor escurecimento das amostras.

TRANSIENT MODEL OF A STATIC EVAPORATOR FOR AN AIR-WATER HEAT PUMP

Published: October 2018

The increasing demand of electric energy in Brazil, allied to the great consumption in rush hour, has stimulated the study of water heating systems that substitute the electric shower. One of these equipments, the solar collector, is the most viable, with the best cost-benefits relation, because Brazil is a tropical country. A heat pump can be used as a support to solar collectors in places where the climatic conditions and/or the lack of available area of solar collection limit the use of the system. One way to improve this heat pump would be the substitution of its conventional evaporator for a static evaporator. This evaporator is constituted of a metallic plate with conformed canals, inside of which the coil is fixed through which the refrigerator cooling of the heat pump flows. The objective of this paper is the development of a mathematical model in transient regimen to simulate the static evaporator operation of an air-water heat pump. Some simulations had been carried through, that had allowed testing geometric parameters of the system, materials for the pipes and plates and different weather conditions. These computational tests had indicated that the model represents a good tool to project static evaporators.
INFLUENCE OF THE MODEL SIZE IN THE NUMERICAL DETERMINATION OF THE AVERAGE THERMAL STRESSES IN AN MMC COMPOSITE

Published: October 2018

In previous works the authors discussed some issues related to a specific metallic matrix composites (MMC), the Aluminum matrix reinforced with SiC particles (Al+SiC) which has a metal matrix (powder) mixed with ceramic particles. These materials have some advantages when used as a structural material such as their high strength and good conformability. Their properties depend, among others, on the volumetric ratio, the  particles size and distribution besides the matrix microstructure itself. Some of them are obtained at elevated temperature what produces a thermal stress state in the material. The Al+SiC is one of the later. The powder mix is extruded at 600oC and it is used at 20oC. Several numerical analyses were performed considering the random distribution of the particles and a non-linear behavior in the aluminum matrix. The results showed strong influence of the aluminum elastic-plastic behavior in the composite thermal stress distribution due to its manufacturing process. However, one issue remained: the size of the model. It represents the central portion of a Al+SiC bar which is only about 10 times the size of a single particle (~10L). The present work investigates, always numerically, the influence of the model size on the thermal stress distribution. It considers 2 sets of non-linear analyses with random distributed particles: one with 20 models with size of 20L each one, the other set with another 20 models with size 40L. This approach allows a view of the results tendency compared with the 10L ones. As done before, the modeled volumetric ratio has a very tight range of values with its average very near to the value in an actual Al+SiC composite. It is showed that the first model size was already enough to get good results without sacrificing neither the computer nor the analyst time.
THEORETICAL ASSESSMENT OF A STIRLING ENGINE 'AMAZON' BY USING PROSA AND MATHCAD

Published: October 2018

This study describes how to build a prototype Stirling engine named Amazon, focusing on how to apply it to generate electric power in remote areas, with an expected power of 8 kW. Such engine was assessed theoretically by using two different computer software, i.e. PROSA and 'a model to simulate Stirling engines by the theory of Schmidt', which was formulated in Mathcad. The results from Mathcad software were on average 6.8% higher than the results from PROSA software. Such fact occurs since Mathcad does not consider the losses in a real system. Hence, the PROSA is generally more accurate in its results. Modeling performed in Mathcad presents higher values for partial loads and similar values for the project operating point.
NATURAL CONVECTION IN RECTANGULAR CAVITIES WITH DIFFERENT ASPECT RATIOS

Published: October 2018

Natural convection in closed cavities has been extensively studied in recent decades. This spontaneous method of heat transfer has a wide range of applications in engineering. In the present work, natural convection was numerically analyzed in a rectangular cavity heated on one of the sides and cooled on the opposite side. Temperatures of the heated wall and of the cooled wall were assumed to be constant. The objective of these studies was to determine the effects of the aspect ratio and the Rayleigh number on flow behavior and heat transfer in the cavity. In the simulations, the Rayleigh number drastically influenced the flow profile and heat transfer inside de cavity, as well as the thickness of the thermal boundary layer. It was also verified that the Nusselt number is strongly dependent on the L/D (Length/Height) ratio, and that this dimensionless variable increases with the increase of the W/L. The simulation of natural convection problems in the CFD Studio satisfactorily described the studied situations.
