Authors: Mohamed Ali Wagdy , Mohamed Ali Khater , Elfeky Ehab Z. , Saleh Mohamed
Published: October 2018

The performance of Differential Evolution is significantly affected by the mutation scheme, which attracts many researchers to develop and enhance the mutation scheme in DE. In this article, the authors introduce an enhanced DE algorithm (EDDE) that utilizes the information given by good individuals and bad individuals in the population. The new mutation scheme maintains effectively the exploration/exploitation balance. Numerical experiments are conducted on 24 test problems presented in CEC'2006, and five constrained engineering problems from the literature for verifying and analyzing the performance of EDDE. The presented algorithm showed competitiveness in some cases and superiority in other cases in terms of robustness, efficiency and quality the of the results.
Bounded, Multidimensional, Integrated Memetic Evolution for Character Recognition Based on Predictive Elimination Theory and Optimization Techniques
Authors: Welekar Rashmi , Thakur Nileshsingh V.
Published: October 2018

This article describes how inspired by the natural process of evolution in genetic algorithms, memetic algorithms (MAs) are a category of cultural evolution phenomenon. The very concept of MA has been discussed in the last few years and is adding newer dimensions to MA and computational skills of algorithms. There are many optimization algorithms which fully exploit the problem under consideration. This article presents a heuristic approach for an improvised algorithm which takes into consideration various optimization parameters in isolation and tries to integrate the self-learning technique of MA. A general structure of MA according to this article should be perfectly in-line with brain activities which are neurotically tested and given maximum emphasis on local search and context-based predictive approaches rather than mathematically computing every event and taking or picking solutions based on results of certain formula. This article goes one step beyond the conventional set of the variety of problem domains, ranging from discrete optimization, continuous optimization, constrained optimization and multi objective optimization in which MAs have been successfully implemented. These optimization techniques must be processed using outcomes of predictive optimization and using a method of elimination to make the search set smaller and smaller as we progress deeper into the search. There is a scarcity of literature and also lack of availability of comprehensive reviews on MAs. The proposed technique is a better approach for solving combinatorial optimization problems. This article gives an overview of various domains and problem types in which MA can be used. Apart from this, the problem of character recognition using predictive optimization and implementation of elimination theory MA is discussed.

Authors: Markovitz Harvey B , Long Mary M. , Fain Deborah , Sandler Dennis
Published: October 2018

A mixed-methods design was used to investigate the skills required for college graduates of sales and marketing programs to be successful. Opinions were sought from campus recruiters, sales and marketing executives, and recent alumni. Online job postings and course syllabi were also examined to identify skills that are both sought and taught. While there are specific skill sets for each discipline, a problem-solving, analytical mindset will go a long way towards landing an entry level job. The curricula must satisfy the needs of both marketing and sales executives, bridging the silos that often exist in university programs between the two disciplines. Recommendations for curriculum development are discussed.

Authors: Singh Ardhendu Shekhar , Shree Sonal , Parahoo Sanjai K
Published: October 2018

The investigation of relationship between teaching and research has flourished for several decades. Teachers' knowledge and their experiences in conducting research studies are collectively expected to enrich the learning process of students. Relevance and applicability of concepts has the potential to augment learners' interest in discussing and absorbing the ideas. Learning can be fulfilling in an environment where teachers propel curiosity amongst students and are in interactive mode through a two-way channel of discussion. It is in this light that this pilot study examines the case teaching method with respect to usage of self-authored cases by the instructor, and compares it with the resultant impact on teaching as well as students' learning when taught with cases authored by others. Participants of the study were students of MBA program in a private university of India. The responses revealed that the two types of teaching materials had impact on areas like clarity, communication, complexity, linking with other topic, preparedness, energy level, and comprehensiveness.

Authors: Shahrabi Saeid , Ehsanpour Ali , Heidary Somayyeh , Shahjahani Mohammad , Maleki Behzad Masumeh
Published: October 2018

Myeloproliferative neoplasms (MPNs) are clonal stem cell disorders characterized by the presence of JAK2V617F mutation. Thrombohemorrhagic as well as autoimmune or inflammatory phenomena are common clinical outcomes of these disorders. Recent studies have shown that abnormality in frequency and function of blood cells manifested by an alteration in CD markers’ expression patterns play a key role in these complications. So, there may be a relationship between CD markers’ expressions and prognosis of JAK2V617F positive MPNs. Therefore, in this review, we have focused on these abnormalities from the perspective of changing expressions of CD markers and assessment of the relationship between these changes with prognosis of JAK2V617F positive MPNs. It can be stated that the abnormal expression of a large number of CD markers can be used as a prognostic biomarker for clinical outcomes including thrombohememorrhagic events, as well as autoimmune and leukemic transformation in JAK2V617F positive MPNs. Considering the possible role of CD markers’ expressions in JAK2V617F MPNs prognosis, further studies are needed to confirm the relationship between the expression of CD markers with prognosis to be able to find an appropriate therapeutic approach via targeting CD markers.

Authors: Nazir Muhammad Ashraf , Izhar Faisal , Tariq Kalsoom , Anjum Khalid Mehmood , Sohail Zaid Bin , Almas Khalid
Published: October 2018

Objective: To evaluate dentists' opinions about the need for a practice management course in the undergraduate dental program. Materials and Methods: This cross-sectional study was conducted in 2017 on practicing dentists in Lahore, Pakistan. A self-administered pilot-tested questionnaire was distributed among 588 dentists using a convenience sampling method to obtain their responses about the need for a practice management course. Descriptive statistics and bivariate and multivariate logistic regression analyses were performed. Results: About 83.8% of 588 dentists completed the questionnaires. There were 36.7% of males and 63.3% of females (mean age 26.22 ± 4.8 years). The principles of patient management (94.1%), time management skills (90.3%), and teamwork (89.2%) were the most commonly agreed topics of the practice management course. The least agreed topics included office design (59.2%), health-care systems (60.9%), and inventory systems (69%). Most participants (74.4%) thought that a practice management course is required to successfully manage a dental practice, and 63% recommended to include the course in the dental curriculum. Multivariate logistic regression showed that dentists working in private clinic (odds ratio (OR): 3.35, P = 0.001), dentists with graduation within ≤ past 5 years (OR: 3.64, P = 0.001), and dentists who attended a practice management course (OR: 3.12, P = 0.001) were more likely to agree to the need of a practice management course to successfully run a dental office. Conclusion: Most dentists believed that a practice management course is required for a successful dental practice. The development and implementation of such a course should be based on the feedback from dentists to ensure evidence-based approaches.

Published: October 2018

This clinical report describes an 8-year follow-up evaluation using different thicknesses of porcelain laminate veneers of diastema and malformed anterior teeth. Minimally invasive treatment with no preparation or minimal reduction options could be considered and chosen based on the characteristics of each case. Laminate veneers with or without reduction can offer an excellent result regarding esthetics and function. Despite its failure without reduction, this treatment is indicated because it can be applied regardless of the structure of the teeth. At first, no tooth preparation with rotatory instruments was performed, and porcelain laminates of minimum thickness were made for the four maxillary anterior teeth. After 6 years, the adhesive interfaces were stained, and the patient was unsatisfied with the esthetics of her smile. Therefore, at that time, the professional decided to prepare the anterior teeth for porcelain laminate veneers. Diastema closure and/or correction of malformed anterior teeth using porcelain laminate veneers is a viable option for the clinician because it restores esthetic harmony. The patient was very pleased with the new laminate veneers.

Published: October 2018

Objective: The aim of this study was to analyze the osteogenic differentiation of rat GMSCs cultured in PRF for bone remodeling. Materials and Methods: GMSCs were isolated from the lower gingival tissue of four healthy, 250 g, 1-month old, male rats (Rattus norvegicus) cut into small fragments, cultured for 2 weeks, and subsequently passaged every 4–5 days. GMSCs isolated in passage 3 were characterized by CD34, CD45, CD44, CD73, CD90, and CD105 using fluorescein isothiocyanate immunocytochemistry (ICC) examination. GMSCs in passage 3–5 cultured in five M24 plates (N = 108; n = 6/group) for 7, 14, and 21 days with three different mediums as follows: Control (−) group: α-Modified Eagle Medium; Control (+) group: High-dose glucose Dulbecco's Modified Eagle's Medium (DMEM-HG) + osteogenic medium; and treatment group: DMEM-HG + osteogenic medium + PRF. GMSCs were osteogenic differentiation cultured in vitro in three different mediums by bone alkaline phosphatase (BALP) and osteocalcin (OSC) marker using ICC monoclonal antibody. Statistical Analysis Used: The one-way analysis of variance was performed (P < 0.05) based on Shapiro–Wilk and Levene's tests (P > 0.05). Results: GMSCs were shown to present + CD44, +CD73, +CD90, +CD105 and − CD34, − and CD45 expression as MSCs markers. The treatment group showed the highest BALP expression (16.00 ± 1.732) on day 7, while OSC expression (13.67 ± 2.309) on day 21 showed the statistically significant difference between groups (P < 0.05). Conclusion: GMSCs cultured in PRF demonstrated potential osteogenic differentiation ability capable of accelerating in vitro bone remodeling by enhancing BALP and OSC expression.

Published: October 2018

Objective: This in situ study evaluated the influence of 10% carbamide peroxide (CP) in combination with different thickeners on physical characteristics of enamel. Materials and Methods: Eighty-four bovine blocks of enamel and dentin (4 mm × 4 mm × 2.5 mm) were divided into seven groups (n = 12), fixed in palatal intraoral devices, and submitted to different treatments: CP + carbopol (FGM), CP + carbopol + glycerin (ultradent), CP + natrosol (experimental gel), carbopol, carbopol + glycerin, and natrosol, without treatment (control group). The physical properties tested were color (ΔE), roughness (Ra), and Knoop microhardness (KHN). Statistical Analysis Used: Data were submitted to ANOVA, Tukey's, and Dunnett's tests (α = 0.05). Results: all groups presented significant color variation, except carbopol. For microhardness, all bleached groups did not differ from control. Roughness increased in all bleached groups when compared to the control group, but CP + natrosol presented statistical lower results than CP + carbopol. Conclusion: Replacement of carbopol by natrosol caused less change on roughness surface, at the same time yielding an effective whitening result.

Authors: Shehadat Saaid Al , Gorduysus Mehmet Omer , Hamid Suzina Sheikh Abdul , Abdullah Nurul Asma , Samsudin Abdul Rani , Ahmad Azlina
Published: October 2018

Objective: The objective of this study was to evaluate and compare the two scanning electron microscope (SEM) preparation protocols and determine the better SEM preparation technique to study stem cells on human amniotic membrane (hAM) scaffold. Materials and Methods: Formaldehyde-based protocol and glutaraldehyde-based protocol were compared to evaluate the quality of SEM images for stem cells cultured on hAM scaffold. Results: The results suggested that formaldehyde-based protocol is better than glutaraldehyde-based protocol in terms of showing clearer topography of the membrane as well as the boarders of the cells. To provide intact surface of the SEM sample and avoid possible ruptures of the hAM or the thin cell layer, it is recommended to perform the dehydration step using graded alcohol concentrations of 20%, 30%, 40%, 50%, 60%, 70%, 80%, and 90%, one time for each and twice in 100% for 10 min each. Gold sputter-coating step is not recommended as it does not improve the image quality. Conclusions: To obtain clear SEM images, it is recommended to run a preliminary study to determine the better chemicals and conditions of sample preparation even when following preexisting protocols.

Published: October 2018

Objective: Chronic periodontitis (CP) is a common inflammatory disease that causes destruction to the supporting tissues of the teeth. Many treatment modalities tried to stop the disease progression. Platelet-rich plasma (PRP) is one of the regenerative methods that used in adjunct to conventional periodontal treatment. The aim of this study was to evaluate the anti-inflammatory effect of PRP by monitoring the lymphocyte count before and after its application to the periodontal pocket. Materials and Methods: Twenty patients, with CP and a pocket depth equal to or deeper than 4 mm, subjected to scaling, root planing, and PRP injection into the pocket. The lymphocyte count measured before and after 1 month from PRP application. Clinical periodontal parameters were taken during two visits (1 month apart), with customized stent fabrication. Results: All clinical periodontal parameters showed a reduction in their value following 1 month of PRP application. . There was a noticeable reduction in lymphocyte count from (mean 2.47 ± 0.91) to (mean 1.94 ± 0.77). Conclusion: In addition to its traditional uses, PRP has a great role in the periodontal treatment by its anti-inflammatory effect.

Published: October 2018

Artemisinin resistance, presently confined to Southeast Asia and associated with mutations in the Plasmodium falciparum K13 (PfK13) propeller domain, represents a serious threat to global malaria control. This study aimed to provide baseline information for future artemisinin resistance surveillance, by analyzing the PfK13 propeller domain in P. falciparum field isolates collected from the Brazilian Amazon Basin between 1984 and 2011. A total of 152 P. falciparum mono-infections were assessed, of which 118 (78%) were collected before and 34 (22%) after the introduction of artemisinin-based combination therapy (ACT) in 2006. An 849-base pair fragment encoding the PfK13 propeller was amplified by nested polymerase chain reaction and sequenced in both directions. The sequences were compared with the reference sequence of P. falciparum 3D7. All samples showed wild-type sequences, thus, no mutations were observed. The results are in agreement with other recent reports and do not provide evidence for presence of PfK13 propeller domain polymorphisms associated with artemisinin resistance among P. falciparum field isolates in the Brazilian Amazon Basin neither before nor after the implementation of ACT.

Published: October 2018

Single crystals of potassium hydrogen phthalate (KAP) are grown by solution growth technique. Linear optical constants are evaluated from UV/VIS/NIR spectrum. The Z scan technique is used to elucidate the third order nonlinearity in the material. The results indicate that the compound exhibits reverse saturable absorption (RSA) and self-defocusing performance. The second harmonic generation (SHG) efficiency of the crystal evaluated by Kurtz and Perry technique is compared with that of the standard KDP crystal. Attempt is made to correlate the SHG efficiency with the crystalline perfection in the material.

On the information content in linear horizontal delay gradients estimated from space geodesy observations
Authors: Elgered Gunnar , Ning Tong , Forkman Peter , Haas Rüdiger
Published: October 2018

Abstract. We assess the quality of estimated linear horizontal gradients in the atmospheric propagation delay above ground-based stations receiving signals from the Global Positioning System (GPS). Gradients are estimated from 11 years of observations from five sites in Sweden. Comparing these gradients with the corresponding ones from the European Centre for Medium-Range Weather Forecasts (ECMWF) analyses show that GPS gradients confirm known seasonal effects both in the hydrostatic and the wet components. The two GPS sites equipped with microwave absorbing material below the antenna in general show higher correlation coefficients with the ECMWF gradients compared to the other three sites. We also estimated gradients using GPS data from two collocated antenna installations at the Onsala Space Observatory. Correlation coefficients for the east and the north wet gradients from GPS can for specific months reach up to 0.8 when compared to simultaneously estimated wet gradients from microwave radiometry. Based on the four years of results we note a strong seasonal dependence, from 0.3 during months with smaller gradients to 0.8 during months with larger gradients, typically during the warmer, and more humid, part of the year. Finally, a case study using a 15 days long continuous Very Long Baseline Interferometry (VLBI) campaign was carried out. The comparison of the gradients estimated from VLBI and GPS data indicates that a homogeneous sampling of the sky is a critical parameter.
Integration of Remote Sense and Geographic Information Systems in Geological Faults Detection in Crete Island, Greece
Authors: Elhag Mohamed , Alshamsi Dalal
Published: October 2018

Abstract. Fracture systems are of great importance in the field of structural geology. Faults commonly afford easy passage to groundwater and fluids such as hydrothermal fluids and magmas (mineral entrapment over the years) or even contribute in earthquake hazard monitoring. For a geologist, it is not always easy to discern such morphotectonic structures at close range (i.e. heavy overgrowth of vegetation). Both remote sensing techniques and spatial modeling (GIS) permit the recognition and better understanding of the brittle tectonics in an area. This study was an effort to delineate the tectonic structures (i.e. fault system) on the Crete Islands by combining Sentinel-2 satellite data and spatial data. For the enhancement and better discrimination of photolineaments primarily recognized on satellite imagery, a variety of enhancement techniques have been applied. The evaluation of a photolineament as a potential fracture zone was based on several factors; the DEM of the study area, the shaded relief, the slopes, and corresponding aspects, the drainage network, the geology and general observations on vegetative coverage appearance. The application of these methods revealed several fracture zones, which we recommend being certified by field investigations. Fault-mapping results may be used for a variety of purposes. Indicative places of large concentration of groundwater are of vital importance for subsequent exploitation by areas of need. Furthermore, because the well-known Anatolian fault zone extends over the Northern part of Crete, the present work may provide useful information for further analysis by geophysicists and seismologists.
Unravelling the impacts of precipitation, temperature and land-cover change for extreme drought over the North American High Plains
Authors: Hein Annette , Condon Laura , Maxwell Reed
Published: October 2018

Abstract. Drought is a natural disaster that may become more common in the future under climate change. It involves changes to temperature, precipitation, and/or land cover, but the relative contributions of each of these factors to overall drought severity is not clear. Here we apply a high-resolution integrated hydrologic model of the High Plains to explore the individual importance of each of these factors and the feedbacks between them. The model was constructed using ParFlow-CLM, which represents surface and subsurface processes in detail with physically based equations. Numerical experiments were run to perturb vegetation, precipitation and temperature separately and in combination. Results show that decreased precipitation caused larger anomalies in evapotranspiration, soil moisture, stream flow and water table levels than did increased temperature or disturbed land cover. However, these factors are not linearly additive when applied in combination; some effects of multi-factor runs came from interactions between temperature, precipitation and land cover. Spatial scale was important in characterizing impacts, as unpredictable and nonlinear impacts at small scales aggregate to predictable, linear large scale behaviour.

Un estudio de la relación entre la empatía y la creatividad en alumnos de Colombia y sus implicaciones educativas
Authors: López-Fernández Verónica , Arias-Castro Cristian , González Restrepo Karen , García Santana Katerine
Published: October 2018

La importancia de las variables cognitivas y emocionales en el aprendizaje es innegable. El presente trabajo busca analizar la relación entre las variables de empatía y creatividad en una muestra de 65 estudiantes colombianos (12,72± 1,57 años, distribuidos en rango entre los 10 y 16 años) en función de la edad y el género. Se empleó un diseño descriptivo y correlacional, así como uno cuasi-experimental en base a los objetivos del análisis. Los resultados muestran que existe correlación estadísticamente significativa y negativa entre la edad y la dimensión cognitiva de la empatía, al igual que ésta con la creatividad. Además, existe correlación significativa y positiva entre la edad y la creatividad y la edad y empatía afectiva. Por otra parte, los análisis de las correlaciones aislando los grupos en función del género reflejan mayor empatía afectiva en el género femenino que en el masculino. Atendiendo a las correlaciones separando los rangos de edad, se apreció que en los estudiantes de mayor edad (14-16 años) existe correlación estadísticamente significativa y positiva entre la creatividad y la empatía cognitiva. En cuanto a las comparaciones entre grupos de muestras independientes, se encontró que la empatía cognitiva es mayor en el grupo de 10 a 13 años, y que la empatía global es mayor en el género femenino. Se discuten los resultados encontrados en este estudio y las implicaciones educativas.
"Yo no me quedo dao": el alumnado ante la violencia escolar
Authors: Pacheco-Salazar Berenice , López-Yáñez Julián
Published: October 2018

Se presentan los resultados de un estudio descriptivo con diseño cualitativo, que buscó identificar las estrategias que ponen en marcha los estudiantes para el abordaje de la violencia escolar. Fue realizado en dos centros educativos de enseñanza primaria en República Dominicana, a partir de una muestra de 604 estudiantes desde quinto hasta octavo grado. Se utilizaron tres técnicas de levantamiento de información: talleres lúdicos-creativos, grupos focales y observación no participante, lo cual implicó una inmersión de cuatro meses en cada centro educativo. Los resultados de la investigación destacan que la principal manera en la que el estudiantado responde ante un episodio de violencia escolar, es reaccionar y defenderse ejerciendo violencia, es decir, “no quedarse dao”. También, pero en menor proporción, buscan ayuda ante personas adultas o delatan el hecho ante las autoridades escolares. Los hallazgos y conclusiones son de relevancia para el diseño e implementación de programas de atención y erradicación de la violencia escolar.

RAZÃO ALUNO/PROFESSOR E CARGA HORÁRIA EM ENSINO DE GRADUAÇÃO NA REGIONAL JATAÍ DA UFG – ANÁLISES PRELIMINARES
Authors: Benite-Ribeiro Sandra Aparecida , Inocêncio Ana Carolina Gondim
Published: October 2018

No presente estudo, com o intuito de avaliar se o quantitativo de docentes é suficiente para a consolidação dos cursos de graduação da Universidade Federal de Goiás, Regional Jataí, foram analisadas as relações entre carga horária dos docentes no ensino de graduação, a carga horária dos Projetos Pedagógicos dos Cursos (PPCs) e o número de vagas autorizadas pelo Ministério da Educação (MEC). Ressaltamos que somente a carga horária de aulas na graduação foi considerada, de forma que os componentes curriculares ministrados nos cursos de pós-graduação, atividades administrativas e acadêmicas, de pesquisa e de extensão não foram computadas. Pela análise da carga horária dos PPCs, seriam necessários 502 docentes no total, para que houvesse esta consolidação, ou seja, seria necessária a contratação de mais 181 professores. Entretanto, pela avaliação da razão entre alunos e docentes, essa ficaria abaixo da razão preconizada pelo MEC. Neste sentido, uma possível solução seria a adequação das cargas horárias dos PPCs ao mínimo exigido pelo MEC, ação esta que contribuiria para amenizar os problemas de cargas horárias excessivas nos cursos de graduação e dos docentes. Apesar desta estratégia, supomos que ainda assim haverá necessidade de obtenção de mais códigos de vagas, mas que só poderão ser devidamente contabilizados e distribuídos após a adequação dos PPCs.

Os dados do Programa foram obtidos do Sistema Integrado de Gestão Acadêmica (SIGAA) – Módulo Stricto Sensu e organizados utilizando-se o programa Excel 2013 da Microsoft®, versão for Windows 10, o que permitiu a montagem de quadros e gráficos para as análises descritivas. Foram incluídos documentos e portarias sobre o referido tema e conteúdos de sites de instituição de ensino superior e técnico pública e privada. Foram excluídos os sites comerciais, blogs e páginas de rede social que relatavam sobre o assunto. O número de programas de MP vem crescendo significativamente no Brasil e, acredita-se que o fato esteja relacionado a aplicação de metodologias de pesquisa que buscam solucionar problemas do cotidiano profissional, bem como sua aplicação prática imediata que estimulam e aumentam a procura determinado o crescimento desta modalidade de pós-graduação. Dos mais de 500 programas de Mestrado Profissional apenas 37 encontram-se no Centro-oeste, e destes, mais de 80% são ofertados em instituições públicas de ensino e apenas dois em Jataí. Observa-se que é indispensável a criação de programas de MP na UFG Regional Jataí, devido à demanda regional, alto número de professores titulados e com perfil profissionalizante convalidando recursos humanos para a abertura destes programas, bem como a proximidade da instituição com outros órgãos públicos e instituições privadas locais e regionais. Portanto, este diagnóstico indica a oferta de programas nas diversas áreas do conhecimento como ciências, tecnologia, saúde e educação.

Published: October 2018

O curso de formação à docência é obrigatório para todos os docentes ingressantes na Universidade Federal da Goiás, que não comprovem experiência prévia no ensino superior. No decorrer dos anos, de 2001 a 2016, muitas alterações foram feitas no modelo do curso com o intuito de melhor atender às necessidades e reinvindicações dos docentes da Regional Jataí (REJ). Assim, o presente estudo teve como objetivos apresentar os modelos de cursos realizados neste período e analisar as críticas dos docentes desta Regional, de forma a fornecer subsídios para a estruturação dos cursos ou de programas de formação de docentes da futura Universidade Federal de Jataí. Os dados foram obtidos dos arquivos da Pró-Reitoria de Graduação e da Coordenação de Graduação da REJ, utilizando-se como instrumento de análise a matriz SWOT e o instrumento de avaliação institucional do MEC. A partir das análises documentais observamos que os modelos mais antigos de cursos, realizados somente com aulas expositivas por docentes externos à Regional Jataí não atendia os anseios dos docentes desta regional, que reagiam com críticas extremamente negativas. Somente a partir do ano de 2015, quando houve maior autonomia da Coordenação de Graduação para a organização do curso e maior participação dos docentes da REJ na execução do curso que críticas construtivas começaram a surgir. Em 2016, quando a Coordenação de Graduação e os docentes locais assumiram o curso e propuseram um modelo mais aplicado ao dia a dia do docente e com atividades práticas, as críticas foram majoritariamente positivas. Assim, concluímos que a avaliação crítica do docente é de grande valia no processo de construção de estratégias e de modelos para formação para a docência no ensino superior. Concluímos também que o processo de formação do docente na REJ satisfaz aos critérios de avaliação do MEC.

Published: October 2018

Este estudo tem como objetivo apresentar um cenário da Monitoria Acadêmica na Regional Jataí e refletir sobre ações administrativas e pedagógicas que permitam fortalecer o Programa e consequentemente o processo de ensino-aprendizagem na Instituição. Inicialmente foi realizada uma revisão sobre a legislação referente aos Programas de Monitoria Acadêmica no Brasil e no âmbito na Universidade Federal de Goiás, buscando avaliar a adequação da Regional ao que a legislação determina. A metodologia adotada na realização dos trabalhos de Diagnóstico parcial constou de levantamento/coleta de dados na Coordenação de Graduação e nas Coordenações de Curso, além de avaliação dos Relatórios Finais de monitores. Foi possível identificar que o Programa de Monitoria Acadêmica da Regional Jataí vem passando por importantes mudanças desde 2015. O principal avanço foi a criação da Comissão Regional de Monitoria, que pôde discutir critérios locais para a divisão de bolsas, respaldado pela Resolução CEPEC Nº 1418 de 2016. O Programa tem ocupado papel importante na melhoria do processo ensino-aprendizagem, contudo é necessário que sejam discutidas estratégias de avaliação e acompanhamento das atividades a fim de assegurar o cumprimento dos objetivos do programa. A adoção de estratégias de ensino-aprendizagem e a ampliação de possibilidade para que a participação dos discentes seja estimulada, são medidas fundamentais para o fortalecimento da monitoria acadêmica.

A common cicada pathogen occurring in bamboo forests of southern China is described as a new species, Tolypocladium dujiaolongae. The previously unknown anamorphic state was obtained from discharged ascospores. Based on its morphological characteristics and a molecular analysis
of the internal transcribed spacer rDNA sequence, we found that the asexual features of T. dujiaolongae are similar to those of Tolypocladium species. The typical characteristics of the fungus are described. The fruiting bodies formed on artificial culture media
were identical to those of natural specimens, strongly supporting the idea that the isolated strain is the asexual stage of T. dujiaolongae. Our results indicate that there is no relationship between Tolypocladium dujiaolongae and the famous traditional Chinese medicine
Isaria cicadae.

Authors: Gannibal Philipp B. , Lawrence Daniel P.
Published: October 2018

Morphological examination of phylogenetically unexamined species of the superseded genus Ulocladium allowed for the inclusion of additional species in Alternaria sect. Pseudoulocladium (2 spp.; total spp. = 6), A. sect. Ulocladioides (3 spp.; total
spp. = 20), and A. sect. Ulocladium (1 sp.; total spp. = 4). Eight new combinations and four replacement names are established to bring nomenclature in accordance with modern Alternaria taxonomy.
ORGANIC RANKINE CYCLE ASSOCIATED WITH AN ABSORPTION CHILLER FOR BIOMASS APPLICATIONS

Published: October 2018

The main goal of this work is to develop a calculation process, based on the second law of thermodynamic, for evaluating the potential of a small Organic Rankine Cycle (ORC) cogeneration (electrical and cooling power) plant using biomass as fuel. Two different configurations and several organic working fluids are presented and assessed. A mathematical model has been developed to find thermodynamically suitable fluids for ORC in biomass cogeneration plants. The main results show that, the family of alkylbenzenes has higher exergetic efficiencies found to be around 16% almost 5 percent higher efficiency than the cycles that use siloxanes as working fluids; in spite of their lower cooling power capacity. The results demonstrate that the cycle efficiency is more dependent on the thermodynamic properties of the working fluids than on the system configuration.
PARTICLE SIZE DISTRIBUTION CORRECTION METHOD USING A SIMULATED ANNEALING TECHNIQUE
Authors: Diógenes A. N. , Santos L. O. E. dos , Fernandes C. P.
Published: October 2018

The procedure for obtaining the particle size distribution by visual inspection of a sample involves stereological errors, given the cut of the sample. A cut particle, supposedly spherical, with radius R, will be counted as a circular particle with radius r, r≤R. The difference between r and R depends on how far from the center of the sphere the cut was performed. This introduces errors when the extrapolation of the properties from two to three dimensions during the analysis of a sample. The usual method is to correct the distribution by probabilistic functions, which have large errors. This paper presents a method to reduce the error inherent to this problem. The method is to compute a simulation of the preparation process in a sample whose structure can be described by non-penetrating spheres of various diameters which meet a known probability distribution function, for example, a log-logistic function, or even a constant function. For each distribution radius, a number of spheres is generated and virtually cut, generating a bi-dimensional (2D) distribution. The 2D curves of the spheres distribution obtained in this simulation are compared with that obtained by the experimental procedure and then the parameters of the threedimensional distribution function are adjusted until the 2D curves are similar to the experimental one using the optimization method Simulated Annealing for the curve-fitting. In future this method will be applied to the analysis of the oil reservoir rocks.
DRYING AND BURNING CHARACTERISTICS OF IPÊ BRANCO WOOD CYLINDERS
Authors: Castro A. , Costa F. S.
Published: October 2018

This work presents the drying and burning characteristics of Ipê Branco (Tabebuia rosco-alba) wood cylinders. The drying, self-ignition, flaming and smoldering phases under a constant heat flux are analysed. The effects of moisture content on characteristic times, mass evolution and consumption rates are described. The Ipê Branco cylinders presented flaming only for moisture contents equal or below 40% on dry basis.  It is verified that the moisture content influences significantly the drying and flaming phases of the burning process of the Ipê Branco cylinders, however there is  no significant effect  on smoldering rates
IMPLEMENTATION OF ENO AND WENO SCHEMES FOR FINITE VOLUME UNSTRUCTURED GRID SOLUTIONS OF COMPRESSIBLE AERODYNAMIC FLOWS
Authors: Wolf W. R. , Azevedo J. L. F.
Published: October 2018

In this work the essentially non-oscillatory schemes (ENO) and the weighted essentially non-oscillatory schemes (WENO) are implemented in a cell centered finite volume context on unstructured meshes. The 2-D Euler equations will be considered to represent the flows of interest. The ENO and WENO schemes have been developed with the purpose of accurately capturing discontinuities appearing in problems governed by hyperbolic conservation laws. In the high Mach number aerodynamic studies of interest in the present paper, these discontinuities are mainly represented by shock waves and contact discontinuities. The entire reconstruction process of ENO and WENO schemes is described in detail for linear polynomials and, therefore, second-order of accuracy. An extension to higher orders of accuracy is presented in the paper in a straightforward manner and applications for compressible flows are shown. These applications compare the accuracy of the schemes with some related data that appear in the references cited in this paper or that come from analytical solutions.
