PERCEPÇÃO DE ESTUDANTES SOBRE SAÚDE, ALIMENTAÇÃO E ATIVIDADE FÍSICA APÓS INTERVENÇÃO COM A METODOLOGIA DA PROBLEMATIZAÇÃO
Authors: Peres Caroline Vargas , Lara Simone , Copetti Jaqueline , Lanes Karoline Goulart , Soares Max Castelhano
Published: June 2018

Nesse trabalho optou-se por abordar temas em saúde, através de metodologias ativas, utilizando a Metodologia da Problematização (MP), uma vez que essa ferramenta propicia ao aluno a valorização da realidade que o cerca, fazendo-o refletir sobre ela. Foram selecionadas duas turmas do 7º ano do Ensino Fundamental, no qual em uma delas trabalhou-se os temas em saúde através de aula expositiva, e a outra, os temas foram abordados pela MP. O instrumento de coleta de dados utilizado foi o Questionário de Percepção de Hábitos Saudáveis, aplicado antes e pós intervenção. Assim, foi possível constatar que houve mudança de percepção nos dois grupos de estudantes após a intervenção, porém na comparação inter-grupos, os estudantes do grupo da MP apresentaram maior conhecimento nos domínios avaliados, quando comparados aos estudantes que participaram da aula expositiva. Com isso, evidencia-se que a MP foi mais eficiente para promover conhecimento sobre as temáticas em saúde, do que as aulas expositivas.
CONTRIBUIÇÕES DA ECONOMIA PARA A ALFABETIZAÇÃO CIENTÍFICA: UMA PROPOSTA PARA A EDUCAÇÃO BÁSICA
Authors: Franzoni Patricia , Del Pino José Claudio , Conceição Oliveira Eniz
Published: June 2018

A Ciência faz parte do cotidiano e saber ciências tornou-se uma condição necessária para que a sociedade possa participar de maneira mais eficiente nos processos de tomada de decisão. É imprescindível que o ensino de ciências garanta a alfabetização científica para os alunos e apresente o conhecimento científico como uma das possibilidades de interpretação do real, sem deixar de levar em consideração outras formas de conhecimento na leitura do mundo. Deste modo, propõe-se uma discussão sobre alfabetização científica e sua importância no ensino de ciências, estabelecendo relações entre economia, tecnologia, sociedade e meio-ambiente. O professor deve desenvolver uma postura dialógica em suas aulas, promovendo debates, trazendo também situações/problemas presentes no nosso cotidiano. Conclui-se que o ensino de ciências não deve se restringir apenas a transmissão de conhecimentos é preciso que se estabeleçam relações entre teoria e prática para se alcançar a alfabetização científica. É importante destacar que a introdução da economia na educação básica, em uma perspectiva de CTS (Ciência, Tecnologia e Sociedade) pode contribuir para alfabetização científica, através do caráter interdisciplinar da ciência, formando pessoas melhor orientadas a respeito da realidade sócio-econômica, o que se reflete nos indicadores de qualidade da educação e no desenvolvimento econômico do país.Palavras-chave: Alfabetização Científica.

Dysfunctional VGSCs are associated with clinical sensory symptoms, such as hyperpselaphesia, parosphresia, and so on.

Conclusion:

This short review highlights the recent advances in the study of VGSCs in sensory information processing and discusses the potential role of VGSCs to serve as pharmacological targets for the treatment of sensory system diseases.
Oxidative Stress: Major Threat in Traumatic Brain Injury
Authors: Khatri Nidhi , Thakur Manisha , Pareek Vikas , Kumar Sandeep , Sharma Sunil , Datusalia Ashok Kumar
Published: June 2018

Background & Objective:

Traumatic Brain Injury (TBI) is one of the major causes of mortality
and morbidity worldwide. It represents mild, moderate and severe effects of physical assault to
brain which may cause sequential, primary or secondary ramifications. Primary injury can be due to
the first physical hit, blow or jolt to one of the brain compartments. The primary injury is then followed
by secondary injury which leads to biochemical, cellular, and physiological changes like blood
brain barrier disruption, inflammation, excitotoxicity, necrosis, apoptosis, mitochondrial dysfunction
and generation of oxidative stress. Apart from this, there is also an immediate increase in glutamate at
the synapses following severe TBI. Excessive glutamate at synapses in turn activates corresponding
NMDA and AMPA receptors that facilitate excessive calcium influx into the neuronal cells. This leads
to the generation of oxidative stress which further leads to mitochondrial dysfunction, lipid peroxidation
and oxidation of proteins and DNA. As a consequence, neuronal cell death takes place and ultimately
people start facing some serious disabilies.

Conclusion:

In the present review we provide extensive overview of the role of reactive oxygen species
(ROS)-induced oxidative stress and its fatal effects on brain after TBI.
Principles of Designing Girls Schools; Promoting Cognitive Development of Iranian Children (Case Study: Primary Schools of Girls in Rasht)
Authors: Talebsafa Mahsa
Published: June 2018

Studies have shown that promoting and cultivating the cognitive development in children aged 7 to 11 is of significance due to their puberty age.Any evaluation in Iran's schooling system is usually bounded by content materials and is less addressed by the significance of the Physical Space of the Educational Environment.In educational settings, the quality of architectural space by affecting the sensory, intellectual and perceptual cognitions can play an essential role in the educational performance. School setting like other educational space can change the formation of behaviors and even the attitude, cognitive development and children's creativity. The child from the actual environment that is marvelously complex would unlimitedly enter into a relationship that is continually developmental and are connected to other relations. These relationships get more complicated due to physical and moral development. The overall changes regularly affect the personality and development of the children, and the educator has to guide and lead them. Nevertheless, it is unfortunately ignored to be in focus. Schools must be provided with appropriate conditions wherein children find the opportunity to develop both physically and mentally.Based on the studies conducted in Iranian schools, the useful elements on children development particularly the cognitive one in the educational setting is not grave. The primary research question in this study is what principles feature in designing female schools to promote the cognitive development and what physical elements can elevate the constitutes of cognitive development.The attempt in this study is to find out the practical elements in forming the physics of schools to promote the cognitive development. Both qualitative and quantitative methods are used. The research design is descriptive. Results were found in a survey-based format. The questionnaire is used as the research instrument. The samples were selected from teachers of female primary schools via interview and questionnaire. The validity and reliability of each were checked hence. Based on the results of the needs and probable obstacles, the case study was conducted with data analysis for further understanding of the subject.

Published: June 2018

A qualitative research case study was conducted over two summers with caretakers and children. The aim was studying how ethnobotanical content-based environmental education (EE) in English classes can impact psychological ownership (PO) of plants. The objectives were to study reactions to classroom scenarios. Subjects were selected through purposive sampling, and data through notes, observation, and recording. The second summer, a questionnaire was integrated into the lesson. Results showed that caretakers hinder children’s enthusiasm about disliked plants. However, they also change their perspectives with EE. Impact on PO increased from traditional teacher-centered lessons, more with crafts, and the most with ingestion. eISSN: 2398-4287 © 2018.

Authors: Avdija Avdi S.
Published: June 2018

Stress is a very common and unavoidable emotional strain among college students. The full domain of college stress has multiple dimensions, each with a unique perspective. The current study examines the unidimensionality and reliability of a 48-items standardized scale designed to measure perceived college stress among students. This Perceived Stress Inventory (PSI) consists of five subscales; each measuring a unique aspect of college stress. To test of unidimensionality and reliability of PSI, factor analysis and psychometric properties were examined. The analyses are based on the data that were collected from 302 college students. The results of this study show that the all five subscales of the Perceived Stress Inventory (PSI) are reliable and each of them is unidimensional.

A PRODUTIVIDADE DA ESCOLA IMPRODUTIVA 30 ANOS DEPOIS: REGRESSÃO SOCIAL E HEGEMONIA ÀS AVESSAS
Authors: Frigotto Gaudêncio
Published: June 2018

No presente texto, busco revisitar, trinta anos depois, o livro A produtividade da escola improdutiva: um (re)exame da relação entre educação e estrutura econômico-social capitalista, destacando a concepção teórica e metodológica centrada no materialismo histórico. A partir deste referencial, aprofundado ao longo de três décadas, sublinho as mudanças na base material e política das relações sociais capitalistas e seu caráter regressivo em todas as esferas da sociedade e cujo preço recai na perda de direitos da classe trabalhadora. No campo educativo, surgem novas noções – sociedade do conhecimento, qualidade total, formação por competências, empregabilidade – que radicalizam o caráter ideológico da noção de capital humano, mascarando a regressão social e educacional subjacente. Nas considerações finais, como interpelação mais aguda do balanço das três décadas, sublinho o desafio no campo da esquerda brasileira, que atua na educação, mas não só com uma melhor compreensão e concretização da relação entre a produção teórica e a ação política.
PEDAGOGIA DAS COMPETÊNCIAS PARA A EDUCAÇÃO PROFISSIONALIZANTE DE NÍVEL SUPERIOR: SÍNTESE, CONCEITO E CRÍTICA
Authors: Santos José
Published: June 2018

O artigo apresenta uma análise teórica sintética sobre a relação existente entre as Diretrizes Curriculares Nacionais Gerais para a Educação Profissional de Nível Tecnológico e alguns autores que se dedicam teórica e empiricamente sobre a “pedagogia das competências” no ensino superior. Do ponto de vista teórico, a comunicação põe em debate a produção acadêmica acerca do paradigma da qualificação e o seu deslocamento discursivo sobre a categoria da competência. A partir desse contexto, e embasado na relação trabalho e educação dentro da tradição marxista, o artigo se debruça especialmente sobre as apropriações acerca do conceito de pedagogia das competências, para considerar, mesmo que de forma abreviada, a existência de interesses capitalistas em demandar para o ensino superior não universitário uma determinada pedagogia, afinada com interesses mercantis.

OS (RE) SIGNIFICADOS DA INFORMALIDADE NO MUNDO DO TRABALHO CONTEMPORÂNEO
Authors: Weil Andreza , Nogueira Marinez
Published: June 2018

A compreensão sobre a dinâmica do mundo do trabalho contemporâneo perpassa um olhar sobre as diversas formas de exploração que se apresentam no atual contexto. Os novos modelos de gestão, impulsionados pela reestruturação produtiva, reconfiguram as relações de trabalho e tem como resultado um alto índice de desemprego. Neste cenário, a Informalidade se apresenta como alternativa para muitos trabalhadores. O que se verifica é que este fenômeno vem ganhando espaço no mundo do trabalho com outras roupagens que em geral tem ocultado o caráter da precarização. Este artigo busca analisar abordagens teóricas acerca da Informalidade e suas particularidades no cenário contemporâneo.
POLÍTICAS PÚBLICAS DE QUALIFICAÇÃO, TRABALHO E RENDA NO GOVERNO LULA: UMA ANÁLISE DOS PROGRAMAS VOLTADOS PARA A JUVENTUDE
Authors: Magalhães Jonas Emanuel
Published: June 2018

O artigo aqui apresentado faz um balanço crítico dos programas de qualificação, trabalho e renda e da Política Nacional de Juventude no governo Lula. Traçando o seu histórico, vê-se que o horizonte colocado para a juventude converge para uma perspectiva de adequação ao modelo econômico vigente, em que a garantia do emprego é substituída pela promessa de empregabilidade. Neste contexto, a inserção produtiva dos jovens no mercado de trabalho dependeria da ampliação do seu capital social, do seu empreendedorismo e do investimento nas competências que o mercado valoriza. Por outro lado, reconhece-se que, no governo Lula, inaugura-se um novo marco para as políticas voltadas para a juventude, a partir do surgimento de espaços institucionais em que se fortalece a disputa pela ampliação de direitos para a população jovem, especialmente aquela em maior situação de vulnerabilidade social.
A TENDÊNCIA PRAGMATISTA E O SEU CARÁTER INSTRUMENTAL: INFLEXÕES TEÓRICAS PRESENTES NA ÁREA DE EDUCAÇÃO

Crystallization Kinetics Of Coconut Oil Based On Gompertz Model
Authors: Mursalin Mursalin
Published: June 2018

The cooling rate and temperature of crystallization has been proven to be very influential on the rate of crystal formation oil. Oil crystallization kinetics can be measured by monitoring changes in the solid fat content(SFC) of oil during cooling process.  In this study, SFC measuredusing pulsed Nuclear Magnetic Resonance (pNMR). Four levels of cooling rates and temperature crystallization studied. Crystallization kinetics parameters were measured by applying the model of Gompertz. Gompertz model used to explain the induction time, the increase in the maximum rate of crystallization and the crystalline polymorphic. Crystallization was done by heating the oil at a temperature of 70°C for 10 minutes prior to rapid cooling to 29°C. Then, rate of cooling from 29°C to the crystallization temperature (critical cooling rate) was set below 2°C/minutes. During the process, the oil was stirred at 15 rpm. Solid fraction was measured periodically since the crystallization temperature was reached until maximum solid fraction was achieved.  The results showed that the Gompertzmodel able to quantitatively describe the crystallization kinetics of coconut oil. Lower critical cooling rate reduces the induction time of crystallization but accelerate the maximum increase rate of crystallization. Crystallization temperature has a negative correlation with the induction time and the maximum increase rate of crystallization. In the crystallization of coconut oil, critical cooling rate and crystallization temperature are only influence on the thermodynamics and kinetics of crystallization but not on its polymorphic formation.

Effects of hall currents with heat and mass transfer on the peristaltic transport of a Casson fluid through a porous medium in a vertical circular cylinder
Authors: El-Dabe Nabil , Moatimid Galal , Mohamed Mona , Mohamed Yasmeen
Published: June 2018

In the current paper, the peristaltic transport of a non-Newtonian fluid obeying a Casson model with heat and mass transfer inside a vertical circular cylinder is studied. The considered system is affected by a strong horizontal uniform magnetic field together with the heat radiation and the Hall current. The problem is modulated mathematically by a system of PDE that describe the basic behavior of the fluid motion. The boundary value problem is analytically solved with the appropriate boundary conditions in accordance with the special case, in the absence of the Eckert number. The solutions are obtained in terms of the modified Bessel function of the first kind. Again, in the general case, the system is solved by means of the homotopy perturbation and then numerically through the Runge-Kutta Merson with a shooting technique. A comparison is done between these two methods. Therefore, the velocity, temperature and concentration distributions are obtained. A set of diagrams are plotted to illustrate the influence of the various physical parameters in the forgoing distributions. Finally, the trapping phenomenon is also discussed.

Authors: Guedri Kamel , Oreijah Mowffaq , Bouzid Abdessattar , Nasr Abdelaziz , Al-Ghamdi Abdulmajeed
Published: June 2018

In this paper, 3-D heterogeneous medium, containing small inhomogeneous zones, subjected to a short-pulse laser has been examined by solving the transient radiative transfer equation. Both curved-line advection method and STEP schemes of the FTn finite volume method have been applied. The curved-line advection method predictions proved that a decrease of the false scattering and ray effects are obtained. In fact, there was a good agreement between the curved-line advection method and the Monte Carlo method. However, the STEP results are slightly mismatching the predictions of the aforementioned reference method. Then, the effects of the absorption coefficient, the size, the number and the position of inhomogeneous zone on the transmittance and reflectance signals have been analyzed. The predictions showed that the increase of the size of the inhomogeneity reduces the intensity of radiation. For both homogenous and heterogonous medium, the change of the detector position varies both the broadening of the signal pulse-width and the time with peak reflectance and/or transmittance. That is can be explained by the effects of the distance and the medium property between the laser-incident source and the detector position. Thus, these both parameters are the main factors for determining the peak position and the pulse broadening. Finally, the effects of the absorption coefficient in the inhomogeneity zone on the absolute values of logarithmic slope has been discussed. The results proved that the absolute values of logarithmic slope may be a perfect indicator for detecting any abnormal absorbing zones in the medium.

Authors: Rehman Khalil , Saba Noor , Zehra Iffat , Malik Muhammad , Bilal Sardar
Published: June 2018

The features of Casson liquid when flow field is thermally stratified are offered in this article. The flow is taken through an inclined cylinder with both MHD fluid and thermal radiations assumptions. A mathematical model is constructed in terms of differential equations via fundamental laws. Since the resultant system is non-linear so a self-coded computational algorithm is implemented to report numerical solution. The obtain observations in this regard are presented by way of both tabular and graphical trends. It is noticed that the Casson fluid temperature is decreasing function of thermal stratification parameter while opposite trend is observed via thermal radiation parameter. Moreover, the cylindrical geometry admits enlarged variations towards involved physical parameters as compared to flat surface.

Authors: Tsukamoto Masanori , Hirokawa Jun , Yokoyama Takeshi
Published: June 2018

Retained foreign bodies sometimes occur in various surgical procedures and can lead to severe complications. Foreign bodies in the oral and maxillofacial region are not rare because of the use of many small items and the natural communication with the outside environment in some areas. We experienced a case of foreign body in the nasal cavity, which was discovered 1 year later at a second operation for hardware removal after maxillofacial surgery. A small, soft material is usually placed between the nasal endotracheal tube and nostril to avoid nasal pressure ulcer at the ala of nose after prolonged anesthesia after our group's experiencing some cases of this complication. The foreign body was found in the pharynx during induction of a second anesthesia. Attention should be directed to not leaving any materials in the patient after surgery. In addition to the normal counts of sponges, needles, etc, other small nonsurgical materials used should be recorded by medical staff to help ensure nothing is retained in the patient.

Authors: Goetz Stephen , Pritts Benjamin , DDS Bryant Cornelius.
Published: June 2018

Sugammadex is a novel drug capable of reversing paralysis induced by the common steroidal nondepolarizing neuromuscular blocking drugs, rocuronium and vecuronium. Reversal is complete at any depth of blockade dependent on the dose of sugammadex administered. This allows rocuronium to be used as a rescue agent in scenarios where succinylcholine is contraindicated. Sugammadex is considered a safe drug with minimal side effects compared with traditional reversal with neostigmine and glycopyrrolate. This article features a case report where succinylcholine was undesirable and rapid reversal of paralysis with sugammadex was used during general anesthesia for dentistry.
True Allergy to Amide Local Anesthetics: A Review and Case Presentation
Authors: Bina Babak , Hersh Elliot V. , Hilario Micael , Alvarez Kenia , McLaughlin Bradford
Published: June 2018

Adverse reactions to local anesthetics are usually a reaction to epinephrine, vasovagal syncope, or overdose toxicity. Allergic reactions to local anesthetics are often attributed to additives such as metabisulfite or methylparaben. True allergic reactions to amide local anesthetics are extremely rare but have been documented. Patients with true allergy to amide local anesthetics present a challenge to the dental practitioner in providing adequate care with appropriate intraoperative pain management. Often, these patients may be treated under general anesthesia. We report a case of a 43-year-old female patient that presented to NYU Lutheran Medical Center Dental Clinic with a documented history of allergy to amide local anesthetics. This case report reviews the use of 1% diphenhydramine with 1:100,000 epinephrine as an alternative local anesthetic and reviews the relevant literature.

Published: June 2018

Intravenous sedation (IVS) is commonly used to complete dental treatment for uncooperative pediatric patients. Propofol (PRO) is widely used for IVS because of its short context sensitive half-time and amnestic effect. However, administering PRO to patients who have a history of egg anaphylaxis is still somewhat controversial. The evidence that supports the potential risks for allergic reactions following PRO use in patients with egg allergies is limited with some anesthesiologists recommending against its use in these patients. Alternative drug regimens for procedural sedation in this population are therefore desirable. Dexmedetomidine (DEX), a selective α-2 agonist, has antianxiety and sedative properties and has been widely used not only for procedural sedation with mild inhibitory effects on respiration but also during minor surgeries for its analgesic effect. In this paper, we describe the successful administration of a combination of DEX and low-dose midazolam (MDZ) for sedation in an uncooperative pediatric patient. Both DEX and MDZ have been reported as safe and useful sedatives for dental treatment, and their combination may provide a helpful option for IVS of pediatric patients for whom PRO is not preferred.
Investigations on laser welding of dissimilar joints of steel and aluminum using a high-power diode laser
Authors: Lahdo Rabi , Springer André , Meier Oliver , Kaierle Stefan , Overmeyer Ludger
Published: June 2018

Lightweight construction is currently of high interest, not only for the automotive sector, but also for the maritime industry, due to various benefits. On the one hand, CO2 emissions can be reduced as a result of lower fuel consumption, and on the other hand a higher speed can be achieved, especially for yachts. Hence, hybrid joints of steel and aluminum parts are in great demand for yachts. Presently, these parts are joined using explosive welding adapters, which are complex, time-consuming, and costly to manufacture. For efficient manufacturing of such adapters, a high-power laser welding process is predestined. Aluminum alloy EN AW-6082 (t = 8 mm) and steel S355 (t = 5 mm) are welded in a lap joint configuration using a diode laser with a laser beam power of 10.4 kW. The challenge of welding this dissimilar material combination is the formation of hard and brittle intermetallic compounds within the weld seam, which may lead to cracks and negative effects on mechanical properties of the joint. To meet the required mechanical properties, the mixing ratio of the intermetallic compounds can be limited, as determined in the context of the presented welding process development. Using suitable mixing ratios, the weld seam quality can be increased as shown in metallography analysis, hardness tests, and tensile shear tests. Among other things, the welded samples provide a shear force of approximately 9 kN.
A Survey on Cryptographic Algorithms Using Fractal Structures
Authors: Aswal Sneh Lata , Negi Ashish
Published: June 2018

Data security has become an important issue in recent times. Confidential data needs to be protected from unauthorized users. Various image encryption techniques have been proposed for the secure transmission of images to protect the authenticity, integrity and confidentiality of images. Fractal images can be used as a strong key for the encryption due to the random and chaotic nature of fractals. The infinite boundaries of fractals provide highly complex structure that leads to confusion and it becomes a tedious task for an unauthenticated user to crack the exact secret fractal key. In this paper, a review of various techniques used for image encryption using fractal geometry has been illustrated. All these techniques have their own advantages and disadvantages in terms of execution time, key generation time and Peak Signal to Noise Ratio.

Published: June 2018

Recently construction companies and real state of SMEs sector of Dubai, reported that they have a combine shortfall of skilled staff of up to 500,000.  In addition to that, recently tourism industry of UAE, one of the most dominating service sectors also reported the severe shortage of qualified hospitality staffs. The shortage of workforce in the industry is one of the major causes of unfair distribution of work load and also an unjust compensation and reward system in the overall industry.  The supply and demand of workforces is also one of the crucial predictor factors for job satisfaction and may lead to quit their job or to migration.While examining the various factors that may affect employee’s intention to leave, many research findings confirmed that job satisfaction caused the highest variance on to leaving intention.  To get the deeper analysis of the job satisfaction and its impact on employee’s intention to leave, many researchers argued that there were many facets of job satisfaction that may cause the leaving intentions and therefore job satisfaction has been considered a variables composed of multiple factors. It is evident that there are many studies had been conducted to examine the relationship between job satisfaction and employees leaving intentions. However, not many studies on the same line have been fully addressed in small and medium size firms in UAE working setting and also most of the studies sampling strategies had focused in industries in developed economies.  Therefore, it is believed to be a gap in the literature in the context of the job satisfaction and intent to leave in SMEs.

A Novel STATCOM Based on Flying Capacitor Modular Multilevel Converter
Authors: Rao T. Sanjeeva , Sowjanya T.
Published: June 2018

A new static synchronous compensator (STATCOM) based on Flying Capacitor modular multilevel converter (DCM2C) is proposed in this thesis. In this converter topology the capacitor voltage is clamped by using a low power rating diode in each sub-module (SM). The quantity of voltage sensors is significantly reduced and is free from the number of voltage levels. Furthermore the voltage balancing control method becomes very simple and the capacitor voltage balance speed is fast. Based on the structure of MMC the DCM2C-STATCOM has the capability of Var compensation and negative sequence current compensation. The topology characteristics and compensation control method of DCM2C-STATCOM are investigated in this thesis. That the capacitor voltage of the proposed DCM2C-STATCOM can be well balanced and the Var and negative-sequence current compensation are effective.
Typology of Technology Platform Goals in Diversified Companies
Authors: Schuh Guenther , Ryschka Simon
Published: June 2018

The significance of technology platforms as networks of technological knowledge is growing in diversified companies. The reason is that technology platforms support diversified companies to handle the conflicting priorities of individualized innovations and generating synergies. Hence, the success of diversified companies can be significantly affected by the systematic design of technology platforms. Key prerequisite for such a systematic platform design is the consistent description of the various technology platform goals. In practice however, companies find it difficult to consistently describe the various technology platform goals due to a lack of methodology. As a consequence, a misalignment between the platform goals and the platform design is noticeable, leading to unsustainable technology platform concepts. Therefore, the authors introduce in this paper an approach to consistently describe technology platform goals in diversified companies. This is done by synthesizing the various variables into a single, unified typology that allows to express complicated relationships among the various variables without resorting to oversimplification. The development of the typology is performed by using a combined deductive and inductive approach on the basis of existing literature as well as knowledge about technology platforms in industrial practice. With the assistance of the typology, diversified companies are able to consistently describe their technology platform goals and design sustainable technology platform concepts.

The objective of this study is to propose a model for the management of risks in the process of access to external sources of technological innovation, as part of a managerial model for open innovation. Taguchi method was used, and data was collected by observation. Empirical evidences were verified, demonstrating the influence and significance of open innovation factors, such as: partnership between companies and universities, the risk of lack of investment in R&D, internal and external, and the absence of intellectual property to maximize the results regarding innovation. Overall, the results demonstrate that technological companies should be open on a day-to-day basis, and have tolerance for a combination of probabilistic risks, as for example, condition to obtain the best results with innovation and to access the external sources of innovation with less associated risk.

Published: June 2018

In today’s world, Social Networking website like Twitter, Facebook , Tumbler, etc. plays a very significant role. Twitter is a micro-blogging platform which provides a tremendous amount of data which can be used for various application of sentiment Analysis like predictions, review, elections, marketing, etc Sentiment Analysis is a process of extracting information from large amount of data, and classifies them into different classes called sentiments. Python is simple yet powerful, high-level, interpreted and dynamic programming language, which is well known for its functionality of processing natural language data by using NLTK (Natural Language Toolkit). NLTK is a library of python, which provides a base for building programs and classification of data. NLTK also provide graphical demonstration for representing various results or trends and it also provide sample data to train and test various classifier respectively. Sentiment classification aims to automatically predict sentiment polarity of users publishing sentiment data. Although traditional classification algorithm can be used to train sentiment classifiers from manually labelled text data, the labelling work can be time-consuming and expensive. Meanwhile, users often use some different words when they express sentiment in different domains. If we directly apply a classifier trained in one domain to other domains, the performance will be very low due to the difference between these domains. In this work, we develop a general solution to sentiment classification when we do not have any labels in target domain but have some labelled data in a different domain, regarded as source domain.
Finite Time Thermodynamic Analysis of a Real Vapour Absorption Refrigeration System with and without Heat Leak
Authors: Khatwani Sanjay , Maheshwari Govind
Published: June 2018

This article presents finite time thermodynamic analysis of a real vapour absorption refrigeration system taking into account both external as well as internal irreversibility. The complete VAR model is assumed to be consisting of two sub-systems. One sub-system (generator-absorber assembly) is assumed as an irreversible heat engine cycle whereas another sub-system (evaporator-condenser assembly) is assumed as an irreversible refrigeration cycle. This study analyzes the effect of presence of heat leak on performance of irreversible (real) vapour absorption refrigeration (VAR) system. This is achieved by adding a heat leakage term into an irreversible model of VAR system. Overall coefficient of performance (COP) of the VAR system is optimized with respect to source/sink side heat exchanger areas using Langrangian multiplier method. Furthermore, the effects of the variations in the cycle parameters on performance deviation of the VAR system are compared with and without heat leak. Results show that effect of rate of heat leak is significant along with the other irreversibilities variations on performance deviation of the VAR system.
