Published: March 2019

A Ciência acadêmica e escolar, muitas vezes, encontra-se compartimentada na forma de disciplinas. Na Universidade essa divisão é bem evidente, com poucas mudanças ao longo
dos  anos.  Entretanto,  na  atualidade,  novos questionamentos  acerca  dessa  organização universitária na forma de disciplinas e saberes disciplinares começam a surgir, tais como: Como construir um conhecimento não-disciplinar? Porém, esse questionamento apesar da importância está longe de se aproximar de suas considerações finais, uma  vez que,
ainda  são  diversas  as  dificuldades  para  o  estabelecimento  de  atividades  e  práticas interdisciplinares  que  unam  os  saberes  produzidos  isoladamente  nas  disciplinas  na
resolução  dos  problemas  da  sociedade.  Continuamos  com  a  antiga  prática  da compartimentação  ou  ênfase  nos  saberes  disciplinares.  O  artigo  em  foco  aborda  as
possibilidades  de  estabelecimento  de  propostas interdisciplinar  no  interior  das universidades,  tendo  como  objetivo  geral  enumerar  e  discorrer  sobre  as  iniciativas
voltadas  para  o  fortalecimento  da  prática  interdisciplinar  na  Universidade  Federal  do Cariri, notadamente nos Campis de Icó e Brejo Santo.

Authors: FERNANDES MARIA APARECIDA
Published: March 2019

Em uma sociedade cada vez mais capitalista, que faz uso dos recursos naturais desordenadamente, torna-se urgente a implantação da educação ambiental para a conquista de novos valores na busca de um desenvolvimento sustentável. Educação essa, que deve ser um processo contínuo de aprendizagem, demonstrando as diversas formas de existência e suas diferentes interligações, explicando a interdependência entre todas as formas de vidas existentes, ensinando valores e ações capazes de contribuírem para a transformação humana na busca da preservação ecológica. Os caminhos a percorrer para construir essa sociedade humana a partir de uma cultura ética e sustentável são os mais diversos possíveis, porém é a educação que nos indica o caminho para assumir conscientemente os princípios fundamentais para o exercício de práticas de cidadania com responsabilidade socioambiental. Nesse contexto, a escola atua como instrumento socializador e colaborador na formação de sujeitos, buscando a construção do saber, da dignidade e do próprio ser humano, ou seja, ensina para a vida. Entre as modalidades de ensino, o ensino básico deve ser visto como uma fase ideal para o ensino e a prática da educação ambiental, pois objetiva desenvolver o educando e assegurar-lhe a formação comum indispensável para o exercício da cidadania, visando identificar-lhe como parte integrante da natureza.

Published: March 2019

: As mudanças nos padrões organizacionais, que primam por políticas de certificação ambiental cada vez mais rígida, visando à preservação do meio ambiente, esquecem-se da educação para o consumo. A expansão do consumo alcança patamares maiores a cada ano, sendo impossível desvincular a prática do consumo do cotidiano dos jovens. Entretanto deve-se compreender a prática de consumir não como nociva, mas passiva de adequação ao cenário atual de escassez de recursos primários. Buscou-se compreender de que forma a Cultura das mídias impacta nas decisões pertinentes ao consumo de bens e serviços relacionados ao público infantojuvenil e qual a percepção desses indivíduos em relação as implicações ao meio ambiente. É neste contexto, que se apresenta o objetivo geral desta pesquisa: verificar a influência da mídia e da escola formal na construção do consumidor infantil e sua conscientização ambiental. Para tanto lançou-se mão de metodologia bibliográfica, exploratória e descritiva, com método quantitativo a partir da aplicação de um questionário misto com 194 estudantes de escolas públicas e privadas. Aponta-se como principal resultado o fato de que a escola se torna ferramenta fundamental na educação dos consumidores que se encontram imersos em teias ilusórias tecidas pela publicidade e reforçadas pelos grupos sociais e seus símbolos. O esclarecimento e direcionamento desse público jovem deve ocorrer dentro da escola, a qual necessita desenvolver nos alunos uma visão holística dos indivíduos e do meio em que vivem, sendo possível a formação de consciência e atitudes preconizadas na avaliação de ações críticas, em prol da sustentabilidade ambiental.

Authors: Loureiro Caroline Vitor , Gorayeb Adryane
Published: March 2019

O crescimento e expansão do setor turístico ocorreu no litoral cearense em áreas dotadas de elevado potencial paisagístico e já ocupadas por comunidades tradicionais pesqueiras e marisqueiras. Como mecanismo de resistência algumas comunidades optaram por associar suas atividades econômicas ao Turismo Comunitário.  O Turismo Comunitário ou Turismo de Base Comunitária (TBC) é uma atividade que se contrapõe ao turismo de massa. Este serviço oferta práticas turísticas que aproximam o turista da cultura e ecossistemas da área receptora, atendendo à uma nova demanda turística que anseia por essa imersão nas atividades locais. Em seus princípios o TBC não substitui as atividades econômicas já existente, ao contrário vem apresentar uma alternativa, mantendo as práticas tradicionais. Diante desse contexto, esse artigo objetiva analisar o desenvolvimento do Turismo Comunitário na zona costeira cearense e avaliar seus benefícios para a economia da comunidade receptora, bem como verificar se recebem apoio ou orientação, e as dificuldades enfrentadas. Para a realização do estudo foram visitadas três comunidades inseridas nas práticas do Turismo Comunitário: Tatajuba localizada no município de Camocim, Curral Velho, localizada no município de Acaraú e Prainha do Canto Verde, localizada no município de Beberibe.

Published: March 2019

Disponibilidade de água e energia elétrica representa condição fundamental ao desenvolvimento econômico e social de qualquer país, sobretudo naqueles em que há dependência entre aqueles elementos e prevalece a hidroeletricidade, como no caso do Brasil. Associado ao aquecimento global, as práticas de uso irracional dos recursos hídricos tem provocado eventos de escassez e crises de desabastecimento jamais vistos. Neste contexto, faz-se necessário conscientizar a população quanto a importância do uso sustentável da água e da energia elétrica a fim de se garantir segurança no abastecimento e mudanças de hábitos que promovam o uso racional daqueles recursos. O ambiente escolar representa espaço propício a reflexão e implementação de tais propostas, sendo este o escopo do presente trabalho. Percebeu-se o interesse dos discentes quanto a temática assim como a necessidade de se aprofundar a discussão dentro das unidades escolares, onde certamente seus frequentadores atuarão como agentes multiplicadores junto aos familiares, vizinhos e comunidade em geral. Foram avaliadas as diferentes percepções dos estudantes dos anos finais dos ensino fundamental e anos finais do ensino médio de uma escola pública de Divinópolis MG, a partir deste diagnóstico desenvolvido um sítio na web que permite a replicação da proposta a qualquer unidade escolar de ensino fundamental ou médio interessada no tema.

Recolección de hongos comestibles silvestres y estrategias para el reconocimiento de especies tóxicas entre los tsotsiles de Chamula, Chiapas, México
Authors: Ruan-Soto Felipe
Published: March 2019

ResumenAntecedentes: En los Altos de Chiapas, los hongos comestibles silvestres son un recurso apreciado, sobre todo por la población indígena tsotsil y tseltal. Sin embargo, en años recientes se ha hecho visible la ocurrencia de intoxicaciones por consumo de hongos. Objetivos: Se describen y analizan las prácticas de recolecta que tienen los tsotsiles de Chamula, cómo han ido cambiando con el tiempo, así como las estrategias para identificar especies comestibles y tóxicas.Método: El estudio se llevó a cabo en Chamula, Chiapas, zona montañosa de bosques templados con población maya tsotsil. Partiendo de un enfoque etnográfico y a través de métodos cualitativos, se realizaron entrevistas no estructuradas y semiestructuradas, así como recolectas de ejemplares fúngicos. Resultados: Antiguamente la recolecta de hongos era una práctica común. Alrededor de 21 especies se enunciaron como comestibles, la mayoría ectomicorrizógenas. Actualmente existe la percepción de que la recolecta no es una práctica frecuente por distintos factores como la disminución de la cobertura forestal o el abandono de estas prácticas de aprovechamiento. Se mencionaron distintas estrategias para reconocer los hongos comestibles.Conclusiones: Aunque la recolecta de hongos subsiste entre los tsotsiles de Chamula, existe un riesgo de salud por la pérdida de conocimientos tradicionales.

A Revised Model for Magneto Convection in Binary Nanofluids
Authors: Sharma Jyoti , Gupta Urvashi , Shukla Shushant
Published: March 2019

The paper presents double-diffusive nanofluid convection under magnetic field using more realistic revised model in which boundaries are assumed to have zero nanoparticle flux. The nanofluid layer includes the nano scale effects (Brownian motion and thermophoresis) and solutal effects (Dufour and Soret). Impact of different parameters is analyzed using normal mode technique and interpreted graphically with the help of the software Mathematica. Complex expressions for oscillatory motions are solved using approximations to confirm their non-existence and onset of convection is established as stationary. Binary nanofluids are found to be much less stable than regular fluids. Higher conductivity of metallic nanofluids makes them less stable as compared to non-metallic nanofluids.

Authors: Mbock Koumbe , Magloire Etoua Remy , Minsili Lezin Seba , Richard Okpwe Mbarga
Published: March 2019

The optimal design of a twenty-five bar space truss commonly involves multiple loading conditions acting on 4 node elements in the linear elastic model. In this paper, we describe the behavior of the truss system with our experimental loading conditions on five node elements subject to minimum displacement and stresses that are used to formulate the constrained nonlinear optimization problem. Numerical computations are developed with the objective of mass minimization and the best structural design is selected by applying the interior point method with the guidance of Matlab Optimization Toolbox. Our numerical results show the optimal values of cross-sectional areas, material densities, and internal forces which satisfy the minimum weight design. These results provide the appropriate mass to the experimental data and allow substantial changes in size, shape, and topology.

Asset Distribution and Peerless Selection Approach for LTE based Multifarious VANET Networks
Authors: Arora Arjun , Rakesh Nitin , Mishra K. K.
Published: March 2019

Vehicular ad-hoc networks (VANET) over the past decade have been always part of research and enthusiasts, bringing in a lot of attention towards them. But with the tremendous swell in the imposition for mobile data VANETs are struggling to meet up. Vehicle to Vehicle (V2V) type of transmission is considered a very successful methodology for assuming trustworthy communication amongst vehicles participating in such communications. In the case of multifarious networks also considering the typical cellular network in which cellular links co-exist with V2V communication by making use of the same resources available in a given spectrum, resulting in a complex scenario. Therefore, it is a challenging issue to tackle with asset distribution and peerless selection. In this paper, a scheme is proposed which shows that peerless selection approach and asset distribution can be used as mixed user utility maximization with consideration of a joint network with the delay in transmission and reduction in power. To minimize the complicacy of computation a distributed algorithm is proposed which boils down towards a near-perfect solution by making use of the Lagrangian technique. The numerical analysis shows the extraordinary gains in throughput can be achieved specially with larger networks. The throughput of the network is also improved because of reduction in power.
Dominant Pole Based Approximation for Discrete Time System
Authors: Richa  , Kumar Awadhesh
Published: March 2019

This paper presents an effective procedure for model order reduction of discrete time control system. The exact model derived from complex dynamic systems proves to be very complicated for analysis, control and design. This necessity brings about using a tool known as model order reduction technique or model simplification. A novel mixed method has been implemented in this paper for reducing the order of the large scale dynamic discrete system. Dominant pole based pole clustering method has been used to derive the coefficients of denominator polynomial while Padé approximation has been applied to obtain the coefficients of numerator polynomial of the reduced order model. The proposed method is quite simple and able to generate a stable reduced order model from high order stable discrete systems. The dominancy of poles has been decided by values of the ratio of residue to its pole. The pole is considered dominant which have larger ratio value. An illustrative example has been considered to show the various reduction steps. The result obtained confirms the effectiveness of the approach.

Authors: Chopra Garima , Ram Mangey
Published: March 2019

The goal of the present study is to investigate the availability and the reliability of the system, which has two dissimilar units in the parallel network under copula. Other key parameters, such as mean time to failure (MTTF) and expected profit are also evaluated. Simultaneous malfunctioning of units, common cause failure and human fault are the causes of system breakdown. The present mathematical model is examined under the assumption that each failure rate is constant and is exponentially distributed. The system undergoes repair in the completely failed state as well as in degraded state. In the case of complete failure, the system is repaired by two repair facilities and that are tackled by utilizing Gumbel-Hougaard family copula. The present system has been studied by applying the concepts of probability theory, supplementary variable technique and Laplace transformation.

Published: March 2019

Mobile commerce (M-commerce) being the subset of e-commerce, signifies a new field of business opportunity. The future of mobile commerce depends on how the mobile users’ intend to adopt this new technology induced business model. With the success of e-commerce in India, there is a huge potential for m-commerce growth. As m-commerce technologies grow and mature, it is the users’ experience and adoption of m-commerce that will drive its growth. The users’ acceptance of m-commerce depends upon various factors, which influence his/her behaviour towards m-commerce. The current research is an effort to identify such antecedents that affects behavioural intention of mobile users towards m-commerce. A survey was conducted among 150 internet mobile users in Chandigarh city using structured self-administered questionnaire to identify such factors. The results show that perceived enjoyment and perceived usefulness are the most important factors followed by trust and perceived cost, which affects mobile users’ behaviour intention to use m-commerce. Perceived ease of use and social influence was not found to have significant influence on mobile users’ behaviour intention. The findings of this research show strong empirical base for all marketers and strategists who are looking to take full advantage of the strength of m-commerce.

Utilization of Symmetric Switching Functions in the Symbolic Reliability Analysis of Multi-State k-out-of-n Systems
Authors: Rushdi Ali Muhammad Ali
Published: March 2019

Symmetric switching functions (SSFs) play a prominent role in the reliability analysis of a binary k-out-of-n: G system, which is a dichotomous system that is successful if and only if at least k out of its n components are successful. The aim of this paper is to extend the utility of SSFs to the reliability analysis of a multi-state k-out-of-n: G system, which is a multi-state system whose multi-valued success is greater than or equal to a certain value j (lying between 1 (the lowest output level) and M (the highest output level)) whenever at least km components are in state m or above for all m such that 1 ≤ m ≤ j. This paper is devoted to the analysis of non-repairable multi-state k-out-of-n: G systems with independent non-identical components. The paper utilizes algebraic techniques of multiple-valued logic (together with known properties of SSFs) to evaluate each of the multiple levels of the system output as an individual binary or propositional function of the system multi-valued inputs. The formula of each of these levels is then written as a probability–ready expression, thereby allowing its immediate conversion, on a one-to-one basis, into a probability or expected value. The symbolic reliability analysis of a commodity-supply system (which serves as a standard gold example of a multi-state k-out-of-n: G system) is completed successfully herein, yielding results that have been checked symbolically, and also were shown to agree numerically with those obtained earlier.

Authors: Vaid Mandeep Kaur , Arora Geeta
Published: March 2019

In this paper, a numerical technique is presented to approximate the solution of a singular perturbed delay differential equation. The continual emerge of singular perturbed delay differential equations in a mathematical model of real life applications trigger the researchers for the numerical treatment of these equations. The numerical technique is based on trigonometric cubic B-spline functions in which derivatives are approximated as a linear sum of basis functions. The obtained matrix system is solved by using the Thomas Algorithm.

Authors: Dey Debasish
Published: March 2019

An unsteady mixed convective flow of micro-polar fluid in a porous medium has been considered in presence of transverse magnetic field, Dufour effects and radiation. Effects of radiation absorption and heat source/sink are taken into account. The Buoyancy force leads to free convection and oscillatory free stream velocity is responsible for forced convection. Partial differential equations governed by conservation principles of mass, momentum and energy are solved analytically using perturbation scheme. Effects of various parameters on the governing fluid motion are shown graphically and numerically in tabular form.

Published: March 2019

Assembly operation occupies major stake in the manufacturing process to obtain the final product. In order to obtain an assembly sequence for a given product, the product should be free of clashes between the parts. To know the clash between the parts, many researchers are followed mathematical models to generate contact data information of the product. These methods will consume much time and search space to extract the information from the product. Current research focuses on developing an automatic algorithm to generate the clash analysis report using macros CATIA V5 R17. In this method, it will not only generate the clash analysis report but also generate a contact information matrix between the parts of the assembly. The developed methodology is implemented on various industrial products to extract the clash information of the product.

Published: March 2019

The present study is an attempt to elucidate mixed convection flow in a shear driven enclosure incorporating silver nanofluid with a square cylindrical heat source placed at several locations. The simplicity from the point of view of computational expense has been achieved by carrying out 2-D simulations using the finite volume method. The effects of the change in heat source locations are studied observing the isotherms and average Nusselt number with respect to the concentration of silver in the nanofluid (0%, 1%, 3%, and 5%) and Richardson number (0.01, 0.1, 1 and 10) as decisive parameters. Prandtl number and Grashof number have been fixed to 6.2 and 104 respectively. The investigation is undertaken for five different locations of the square cylindrical heater. The study shows that maximum heat dissipation at higher Reynolds number occurs when the heater is placed near the bottom right corner of the enclosure; whereas in case of low Reynolds number, the heater when placed near the top left a corner of the enclosure yields maximum heat transfer. The investigation also yields a positive correlation between average Nusselt number with increasing silver concentration.

Published: March 2019

Meta-heuristic algorithms are used to get optimal solutions in different engineering branches. Here four types of meta-heuristics algorithms are used such as evolutionary algorithms, swarm-based algorithms, physics based algorithms and human based algorithms respectively. Swarm based meta-heuristic algorithms are given more effective result in optimization problem issues and these are generated global optimal solution. Existing swarm intelligence techniques are suffered with poor exploitation and exploration in given search space. Therefore, in this paper Hybrid Artificial Grasshopper Optimization (HAGOA) meta-heuristic algorithm is proposed to improve the exploitation and exploration in given search space. HAGOA is inherited Salp swarm behaviors. HAGOA performs balancing in exploitation and exploration search space. It is capable to make chain system between exploitation and exploration phases. The efficiency of HAGOA meta-heuristic algorithm will analyze using 19 benchmarks functions from F1 to F19. In this paper, HAGOA algorithm is performed efficiency analyze test with Artificial Grasshopper optimization (AGOA), Hybrid Artificial Bee Colony with Salp (HABCS), Modified Artificial Bee Colony (MABC), and Modify Particle Swarm Optimization (MPSO) swarm based meta-heuristic algorithms using uni-modal and multi-modal functions in MATLAB. Comparison results are shown that HAGOA meta-heuristic algorithm is performed better efficiency than other swarm intelligence algorithms on the basics of high exploitation, high exploration, and high convergence rate. It also performed perfect balancing between exploitation and exploration in given search space.

This paper deals with a batch arrival that customers arrive to the system according to a compound Poisson process. The customer’s behavior is incorporated according to which loss with a certain probability and the server begins to provide a service only when a queue size minimum say ‘a’ and maximum service capacity is ‘b’. Once the server completes the service, the unsatisfied customers may get the same service under Bernoulli schedule is termed as instantaneous Bernoulli feedback. The occurrence of negative customer cause the server to fail and removes a group of customers or an amount of work if present upon its arrival. As soon as the failure instant, the service channel send to the two delays of verification, the first verification delay starts before the repair process and the second verification delay begins after the repair process. We use the generating function method to derive the stationary queue size distribution. Some important performance measures such as different states of the system and the expected length of the queue explicitly. Some important special cases and numerical examples are determined.

Published: March 2019

In recent years, Sentimental Analysis is used in all online product firms. The number of users using the particular product has increased which makes the industry to improvise the characteristics of the product. These days, many users who are using websites, blogs, online shopping tends to review the products they used. These reviews were taken into consideration by other users during their search for products. Hence the industry has found the root of delivering the correct product searched by the user based on the reviews of the users using the concept of sentimental analysis. Sentimental Analysis is the concept of data analysis where the collections of reviews are taken into consideration, and those reviews are analyzed, processed and recommended to the user. The reviews given are longer and which consist of a few paragraphs of content. In this paper, the dataset is collected from the official product sites. Initially, these reviews must be pre-processed in order to remove the unwanted data’s such as stop words, be verbs, punctuations, and conjunctions. Once, the pre-processing is over the trained dataset is classified using Naive Bayes and SVM algorithm. These existing algorithms provided the accuracy which is not worth enough. Hence, an ensemble approach has been applied to enhance the accuracy of the given reviews. An ensemble is a classification approach by combining two or more algorithms and calculate the mode value based on the vote reference for every algorithm which is used. In this paper, Naive Bayes, SVM, and Ensemble algorithm are combined. We proposed an Ensemble method that helps in providing better accuracy than the current existing algorithm. Once the accuracy is calculated, based on the reviews, the particular product is recommended for the user.
