Logística Reversa das Embalagens Vazias de Agrotóxicos: Conscientizar para Fomentar um Agronegócio Sustentável
Authors: Souza Jaqueline Aparecida Boni , Souza Júnior Ivo Pereira de , Vieira Silvia Cristina
Published: June 2017

O Brasil está entre os maiores consumidores mundiais de agrotóxicos o que pode reverberar interferências diretas ao meio ambiente. O uso de agrotóxicos na agricultura brasileira corrobora com a farta produtividade. Contudo, tende a reverberar ações antrópicas com efeitos ambientais nocivos. Para minimizar impactos do agronegócio, o modelo nacional de devolução das embalagens vazias de agrotóxicos tornou-se referência mundial em sustentabilidade. Esse artigo tem como objetivo geral identificar fatores de conscientização sustentável no agronegócio, quanto à logística reversa das embalagens vazias de agrotóxicos no Brasil. De maneira específica, objetiva-se pontuar a importância do profissional engenheiro agrônomo, neste processo de educação ambiental informal sobre a prática da devolução correta das embalagens vazias de agrotóxicos. A atual pesquisa buscou trazer elementos existentes na legislação e a relevância da conscientização dos atores por meio do papel do engenheiro agrônomo, neste processo de educação ambiental informal. Este ensaio segue a linha de pesquisa qualitativa, ancorado em revisão bibliográfica e documental com aporte da legislação sobre a Logística Reversa das Embalagens Vazias de Agrotóxicos em harmonia com a Política Nacional de Resíduos Sólidos. Foram observadas diversas contribuições de sucesso para conscientização do manejo sustentável dos agrotóxicos como o Programa Sistema Campo Limpo do Instituto Nacional de Processamento de Embalagens Vazias complementado pela atuação profissional de engenheiros agrônomos. Contudo, ainda ocorre a necessidade de uma maior atenção para o assunto, notou-se baixo potencial de coalizão visando efetivar melhor desenvoltura nas relações entre a rede de responsabilidade compartilhada para promover a logística reversa das embalagens de agrotóxicos. PALAVRAS-CHAVE: Logística reversa. Agrotóxico. Sustentabilidade.
O potencial educativo das praças como espaço educador sustentável
Authors: Amaral Gabriel Buffon do , Santos Ricardo Miranda dos
Published: June 2017

Compreendemos que um espaço educador é aquele que desenvolve a capacidade da sociedade em tornar-se também sustentável. O ambiente escolar em si, é, frequentemente, objeto de estudos por este enfoque na aplicação prática de projetos de educação ambiental. Todavia, outros espaços além da escola também podem ser alvo destes projetos e, atualmente, vêm ganhando espaço no campo teórico por demonstrarem seu potencial educacional e de conscientização social. Dentre eles, uma em especial ganha destaque, as praças. Isto se deve ao espaço privilegiado que a praça proporciona a seus usuários, com convivência entre várias gerações, seja por meio da prática de esporte, ou até mesmo pelo lazer propiciado. Esta transposição do espaço escolar possibilita que o estudante aguce seu olhar para o mundo, incentivando a curiosidade para a pesquisa e aprendizado sobre o meio ambiente. Atualmente, para despertar a curiosidade ambiental, não podemos nos prender aos limites dos espaços formais da sala de aula. Assim, sob o enfoque de tentar entender se há a formação, ou não, de um espaço educador sustentável na praça pública Marcílio Augusto Pinto – MAP, em Iguatemi/MS, o presente estudo, por meio da observação, diagnóstico dos equipamentos urbanos/paisagísticos, entrevista com seus frequentadores e confrontação destes com o referencial teórico levantado, identificou que o ambiente específico do estudo (Praça Marcílio Augusto Pinto) demonstrou um baixo potencial educativo na situação em que se encontra.  PALAVRAS-CHAVE: Espaço Educador. Educação Ambiental. Praça.
A Imagem como Fantasma em Os Cus de Judas, de Antônio Lobo Antunes
Authors: Junior Norival Bottos
Published: June 2017

Resumo: o presente artigo procura investigar as imagens de resistência do horror no romance ‘Os Cus de Judas’, de Antonio Lobo Antunes, que narra a experiência traumática da guerra em Angola no período em que Portugal encerrava sua fase de exploração colonial. Dentre os vários temas propostos neste romance escolheu-se o problema do sintoma como ocultamento de certas imagens que retornam muito tempo depois na condição de fantasmas à consciência do narrador inominado, depois de muitos anos de inexplicável silêncio. Utilizaremos o aporte teórico de Giorgio Agamben e Georges Didi-Huberman sobre o caráter fantasmático das imagens do horror da guerra, ou seja, tentar alcançar o objeto perdido, mesmo sabendo, de antemão, que se trata de uma tarefa impossível, eis a relação que os dois filósofos estabelecem entre o que está perdido de maneira irremediável e o fantasma imagético da perda, o fantasmático pode ser percebido como um modo de sublimação.

An Evaluation of Corporate Governance Disclosure in Ghanaian and Nigerian Banks
Authors: Araniyar C. Isukul , John J. Chizea
Published: June 2017

Corporate governance disclosure has become the buzz word for countries in developing economies, with the spate of corporate governance failures and the need to prevent a continuation of this trend. There has been the call for developing countries to enhance and improve on corporate governance disclosure practices. This study examines corporate governance disclosure in Ghanaian and Nigerian Banks using the un-weighted disclosure index technique. This research analyses corporate governance disclosure practices in the annual reports of 10 listed banks in Ghanaian and Nigerian banks in the year 2014. The findings of the research reveal that Ghanaian and Nigerian banks comply with several codes and principles of corporate governance disclosure: with Ghanaian banks having a lower level of disclosure than their Nigerian counterparts. On closer inspection, both Ghanaian and Nigerian banks have poor scores in voluntary corporate governance disclosure. Ghanaian banks tend to be worse off, as the level of variation in levels of corporate governance disclosure is higher than Nigerian banks. In comparison, Nigerian banks on the average tend to have better voluntary disclosure practices than Ghanaian banks. Also, Ghanaian and Nigerian banks include some elements of corporate social responsibility reporting in their annual reports. The research recommends that policymakers and regulators should devise policies targeted at enhancing voluntary corporate governance disclosure and increasing board diversity in the boardrooms.
The One Abutment–One Time Protocol: A Systematic Review and Meta‐Analysis
Authors: Atieh Momen A. , Tawse‐Smith Andrew , Alsabeeha Nabeel H.M. , Ma Sunyoung , Duncan Warwick J.
Published: June 2017

Background: The use of definitive abutments (DAs) at time of implant placement has been introduced to overcome limitations of dis/reconnection of healing/provisional abutments (PAs). With little and inconsistent information in the literature regarding the effectiveness of using DAs, the aim of this systematic review is to examine marginal bone and soft tissue level changes, technical and biologic complications, and implant failure rate associated with use of DAs and PAs.

Methods: This systematic review was prepared according to guidelines of the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses statement. MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and online trial registers were searched for studies comparing use of DAs and PAs. The Cochrane Collaboration risk of bias tool was used to assess selected studies, and meta‐analyses were performed using statistical software.

Results: A total of 1,124 citations were identified. Of these, seven trials with 363 dental implants in 262 participants were included in the analysis. Pooled estimates for marginal bone level changes showed significant differences between the two prosthetic techniques in favor of using DAs. No significant differences were found in soft tissue level changes, technical and biologic complications, or implant failure rate.

Conclusions: Within the limitations of this review, DAs appear to be a viable alternative to PAs at time of implant placement. However, favorable changes in peri‐implant marginal bone level associated with use of DAs should be viewed with caution as its clinical significance is still uncertain.
APROXIMACIÓN CONCEPTUAL Y PRÁCTICA A LOS MODELOS DE ECUACIONES ESTRUCTURALES
Authors: Medrano Leonardo Adrián , Muñoz-Navarro Roger
Published: June 2017

En el presente trabajo se expone una aproximación conceptual y práctica a los Modelos de Ecuaciones Estructurales o Structural Equation Modeling (SEM). Los SEM están considerados entre las herramientas más potentes para el estudio de relaciones causales en datos no experimentales. Son una combinación del análisis factorial y la regresión múltiple y están compuestos por dos componentes: el modelo de medida y el modelo estructural. El modelo de medida describe la relación existente entre una serie de variables observables; mientras que en el modelo estructural se especifican las relaciones hipotetizadas entre las variables, es decir, se describen las relaciones entre las variables latentes mediante el uso de flechas. Llevar a cabo un SEM involucra cinco etapas: 1) Especificación del Modelo; 2) Identificación del Modelo; 3) Estimación del Modelo; 4) Evaluación del Modelo y 5) Re-especificación del Modelo. El presente artículo provee una serie de guías de “buenas prácticas” para realizar análisis SEM, con ejemplos utilizando el programa AMOS.

Authors: Melo Fiallos Diego Fernando , Silva Chávez Judith Alexandra , Indacochea Mendoza Luis Rene , Núñez Campaña Jorge Humberto
Published: June 2017

En el presente artículo se hace un análisis sobre la implementación de tecnologías de información y comunicación en la educación superior con el objetivo de aportar conocimiento sobre las tendencias en su apropiación social. Para ello se ha hecho una revisión de documentos de política pública y literatura científica, que contienen las directrices planteadas por organismos internacionales en las cuales se presentan diferentes alternativas para orientar el proceso de integración de las tecnologías en la formación. Seguidamente se comentan algunos estudios acerca de problemáticas surgidas en el proceso de apropiación tecnológica sin un cambio en el proceso de enseñanza - aprendizaje, para lo cual se discute la teoría de aprendizaje conectivista como posible marco de referencia. Las conclusiones apuntan a centrar la atención en los procesos de aprendizaje más que a la inversión en equipamientos, subrayando la importancia de las tecnologías en la educación, en el contexto de la cuarta revolución industrial en la era digital.

The Role of Respiration in Estimation of Net Carbon Cycle: Coupling Soil Carbon Dynamics and Canopy Turnover in a Novel Version of 3D-CMCC Forest Ecosystem Model
Authors: Marconi Sergio , Chiti Tommaso , Nole Angelo , Valentini Riccardo , Collalti Alessio
Published: June 2017

Understanding the dynamics of Organic Carbon mineralization is fundamental in forecasting biosphere to atmosphere Net Carbon Ecosystem Exchange (NEE). With this perspective, we developed 3D-CMCC-PSM, a new version of the hybrid Process Based Model 3D‐CMCC FEM where also heterotrophic respiration (Rh) is explicitly simulated. The aim was to quantify NEE as a forward problem, by subtracting Ecosystem Respiration (Reco) to Gross Primary Productivity (GPP). To do so, we developed a simplification of the Soil Carbon dynamics routine proposed in DNDC [1]. The method calculates decomposition as a function of soil moisture, temperature, state of the organic compartments, and relative abundance of microbial pools. Given the pulse dynamics of soil respiration, we introduced modifications in some of the principal constitutive relations involved in phenology and littering sub-routines. We quantified the model structure related uncertainty in NEE, by running our training simulations over 1000 random parameter-sets extracted from parameters distributions expected from literature. 3D-CMCC-PSM predictability was tested on independent time series for 6 Fluxnet sites. The model resulted in daily and monthly estimations highly consistent with the observed time series. It showed lower predictability in Mediterranean ecosystems, suggesting that it may need further improvements in addressing evapotranspiration and water dynamics.
An Exploratory Assessment of Significant Tourism Sustainability Indicators for a Montane-Based Route in the Drakensberg Mountains
Authors: Mutana Sarudzai , Mukwada Geoffrey
Published: June 2017

This paper assesses the use the Global Sustainable Tourism Criteria (GSTC) indicators for monitoring tourism along a mountainous route. The study was carried out along a mountain route in the Drakensberg Mountains of South Africa. A survey was carried out among tourism businesses, local communities and local government officials located along the Maluti Route, which passes though the eastern part of the Free State Province of South Africa. This study constitutes the first assessment in which the GSTC indicators are applied in the assessment of the sustainability of route tourism in South Africa. The study first evaluated the importance of each indicator by considering the level of application in tourism business organisations before examining the perceptions of local community members and local government officials regarding the applicability of the indicators in the assessment of tourism sustainability. The results suggest that there is a general appreciation of tourism sustainability among tourism business operators although shortcomings were evident on environmental and socio-economic indicators. In conclusion, the paper suggests ways through which tourism sustainability could be enhanced among different players along the Maluti Route.
The Social Representation of Feminism within the On-line Movement “Women Against Feminism”
Authors: Crusmac Oana
Published: June 2017

The present paper aims to analyse the social representation of feminism within the “Women Against Feminism” (WAF) on-line movement that is based on a shared blog which gained significant coverage in the U.S. and U.K. media since the summer of 2014. Using the method of quantitative content analysis and the insights provided by social representations theory, the paper will disclose what lies behind the concept of ‘feminism’ for the group embracing the WAF movement and also aims to find whether the members of this on-line community can be described as postfeminists. The article will conclude that the social representation of feminism within the WAF on-line movement is not based on a lack of information, but rather on a stereotypical understanding of the concept and on a non-nuanced perspective upon the history of feminism and its current developments (in particular the difference between post-feminism and third wave feminism). Moreover, similar arguments raised against feminism have been also drawn in the past, WAF sharing similar arguments with the ‘80s media backlash against feminsim.
THE IMPACT OF INTERNAL FACTORS ON SMALL BUSINESS SUCCESS: A CASE OF SMALL ENTERPRISES UNDER THE FELDA SCHEME
Authors: Khadijah Mohamad Radzi  , Mohammad Nazri Mohd Nor  , Suhana Mohezar Ali
Published: June 2017

This study attempts to identify the antecedents of business success in the Malaysian perspective, with particular reference to small businesses under the Federal Land Development Authority (FELDA) scheme. Cross sectional data were collected from 199 small businesses operating under the (FELDA) scheme via questionnaire. The data collected were analysed using partial least square method. The empirical results indicated that only entrepreneurial competency and technology usage are related to successes of small businesses. However, this study found insufficient empirical evidence to support the relationship between marketing capability, financial resources, knowledge sharing, and business success. As this study was confined to the small businesses under the FELDA scheme, this provides valuable findings by uncovering the differences among the critical success factors due to the different reasons for formation of the small businesses. The insights gained from this study could facilitate industry practitioners to develop comprehensive business strategies and effective institutional policies to maintain the global competitiveness of small businesses under the FELDA scheme.
IDENTIFYING THE ANTECEDENTS FOR RELATIONSHIP QUALITY MODEL AND ITS OUTCOMES FOR PRIORITY BANKING CUSTOMERS IN INDONESIA
Authors: Syafrizal  , Nabsiah Abdul Wahid  , Ishak Ismail
Published: June 2017

Indonesian banks have started to focus on finding the right relationship quality model to be applied to their day-to-day operation, particularly for their priority banking customers (PBC) who contribute the most to their profitable growth. This study investigates firstly, whether positive emotional expression (PEE) acts as the antecedent to relationship quality (satisfaction and trust); and secondly, whether relationship quality (RQ) leads to wordof- mouth (WOM) and share-of-purchase (SOP) as its positive outcomes. Results from a survey carried out on 338 priority banking customers in Jakarta, Indonesia found that indeed PEE acts as the antecedent to RQ while RQ is positively linked to the WOM and SOP outcomes. These findings suggest that PEE, WOM, and SOP are variables that must be considered by Indonesian banks when they strategise to enhance the relationship quality of their priority banking customers.
Na+,K+-ATPase as a Target for Treatment of Tissue Fibrosis
Authors: Orlov Sergei N. , La Jennifer , Smolyaninova Larisa V. , Dulin Nickolai O.
Published: June 2017

Myofibroblast activation is a critical process in the pathogenesis of tissue fibrosis accounting for 45% of all deaths. No effective therapies are available for the treatment of fibrotic diseases. We focus our mini-review on recent data showing that cardiotonic steroids (CTS) that are known as potent inhibitors of Na+,K+-ATPase affect myofibroblast differentiation in a cell type-specific manner. In cultured human lung fibroblasts (HLF), epithelial cells, and cancer-associated fibroblasts, CTS blocked myofibroblast differentiation triggered by profibrotic cytokine TGF-β. In contrast, in the absence of TGF-β, CTS augmented myofibroblast differentiation of cultured cardiac fibroblasts. The cell type-specific action of CTS in myofibroblast differentiation is consistent with data obtained in in vivo studies. Thus, infusion of ouabain via osmotic mini-pumps attenuated the development of lung fibrosis in bleomycintreated mice, whereas marinobufagenin stimulated renal and cardiac fibrosis in rats with experimental renal injury. In TGF-β-treated HLF, suppression of myofibroblast differentiation by ouabain is mediated by elevation of the [Na+]i/[K+]i ratio and is accompanied by upregulation of cyclooxygenase COX-2 and downregulation of TGF-β receptor TGFBR2. Augmented expression of COX-2 is abolished by inhibition of Na+/Ca2+ exchanger, suggesting a key role of [Ca2+]i-mediated signaling. What is the relative impact in tissue fibrosis of [Na+]i,[K+]iindependent signaling documented in several types of CTS-treated cells? Do the different conformational transitions of Na+,K+-ATPase α1 subunit in the presence of ouabain and marinobufagenin contribute to their distinct involvement in myofibroblast differentiation? Additional experiments should be done to answer these questions and to develop novel pharmacological approaches for the treatment of fibrosis-related disorders.
Musical Expectancy in Squat Sonification for People Who Struggle with Physical Activity
Authors: Newbold Joseph W. , Bianchi-Berthouze Nadia , Gold Nicolas E.
Published: June 2017

Physical activity is important for a healthy lifestyle. However, it can be hard to stay engaged with exercise and this can often lead to avoidance. Sonification has been used to support physical activity through the optimisation/correction of movement. Though previous work has shown how sonification can improve movement execution and motivation, the specific mechanisms of motivation have yet to be investigated in the context of challenging exercises. We investigate the role of music expectancy as a way to leverage people’s implicit and embodied understanding of music within move- ment sonification to provide information on technique while also motivating continuation of movement and rewarding its completion. The paper presents two studies showing how this musically-informed sonification can be used to support the squat movement. The results show how musical expectancy impacted people’s perception of their own movement, in terms of reward, motivation and movement behaviour and the way in which they moved.
Participatory Design Research Methodologies: A Case Study in Dancer Sonification
Authors: Landry Steven , Jeon Myounghoon
Published: June 2017

Given that embodied interaction is widespread in Human-Computer Interaction, interests on the importance of body movements and emotions are gradually increasing. The present paper describes our process of designing and testing a dancer sonification system using a participatory design research methodology. The end goal of the dancer sonification project is to have dancers generate aesthetically pleasing music in real-time based on their dance gestures, instead of dancing to prerecorded music. The generated music should reflect both the kinetic activities and affective contents of the dancer’s movement. To accomplish these goals, expert dancers and musicians were recruited as domain experts in affective gesture and auditory communication. Much of the dancer sonification literature focuses exclusively on describing the final performance piece or the techniques used to process motion data into auditory control parameters. This paper focuses on the methods we used to identify, select, and test the most appropriate motion to sound mappings for a dancer sonification system.

La cientificidad de las ciencias de la información: fundamentación filosófica o resolución de problemas
Authors: Melogno Pablo
Published: June 2017

Se presenta una discusión acerca de las condiciones de cientificidad de las ciencias de la información a partir de las ideas de Thomas Kuhn. Se realiza una revisión de las diferentes acepciones del concepto de paradigma, y de las diferencias señaladas por Kuhn entre las ciencias naturales y las ciencias sociales. Se revisa la perspectiva kuhniana de que las diferencias entre ambos tipos de disciplinas están dadas por la ausencia de debates acerca de los fundamentos y la naturaleza disciplinar en las ciencias naturales, y la ausencia de tradiciones consolidadas de resolución de problemas en las ciencias sociales. En función de esto, se busca establecer que las estrategias de fundamentación filosófica de una disciplina no son definitorias para determinar su carácter científico, en cuanto la condición fundamental para la consolidación paradigmática radica en la conformación de una tradición exitosa de resolución de problemas, y en la asunción de elementos metodológicos y teóricos que no se someten a cuestionamiento.
Portales educativos españoles: revisión y análisis del uso de servicios Web 2.0
Authors: Martínez Méndez Francisco Javier , López Carreño Rosana
Published: June 2017

La nueva forma de construir sitios web coloca al usu-rio en un lugar mucho más protagónico, de manera que puede participar de forma más activa. La Web se entiende ahora como la plataforma sobre la que se desa-rrollan las aplicaciones y a través de la cual los usuarios interaccionan con ella, porque las necesidades de los usuarios van más allá de la mera consulta de documentos publicados por otros autores, ahora sienten interés en editar ellos mismos sus documentos, bien de forma individual (un blog, por ejemplo) o de forma colectiva (una wiki, por ejemplo). Este nuevo paradigma se co-noce con el nombre de web 2.0 e incorpora una serie de ideas y servicios que le otorgan al usuario mayor capacidad de participación, las cuales pueden ser aprovechadas de forma muy interesante por las comunidades educativas, bien de forma personal o bien apoyándose en los recursos que disponen para ello las comunidades autónomas españolas en la Web, donde desarrollan y mantienen portales que comienzan a integrar productos y servicios 2.0, que ofrecen al usuario mayor participación y personalización de su espacio personal. El objetivo de este estudio es revisar la presencia y uso de estos productos y servicios en este tipo de portales. Los resultados obtenidos nos muestran que se ha iniciado el proceso de adaptación e implementación hacia los portales educativos 2.0 pero que aún queda mucho camino por recorrer. Asimismo, y como era previsible, se han detectado grandes diferencias entre unos portales y otros en cuanto a su grado de desarrollo.

Időszakos vagy megosztott idejű tulajdonlás a közös tulajdon speciális esete új szabályként került a román polgári törvénykönyvbe 2011. október elsejétől.

A tulajdonjog részjogosítványai nem feltétlenül egyformán és egyidejűleg gyakorolhatók. A tulajdon részjogosítványai közül a birtoklás annak ellenére folyamatosnak tekinthető, hogy egymást követő időszakok, szünetek vannak az ingóságok használatában.

Külön fejezetben kerül bemutatásra az időszakos tulajdon fogalma, meghatározása.

Az időszakos tulajdon több módon is keletkezhet, így megállapodással vagy végrendeleti örökléssel. Bemutatásra kerül, hogyan gyakorolhatja a tulajdonos ebben a tulajdonosi formában a tulajdoni részjogosítványokat. A polgári perrel kapcsolatos szabályok körében ismerhetjük meg a jogviták elrendezési lehetőségeit, így a társtulajdonos kérheti a közös tulajdon megszüntetését, de pénzbeli kompenzációt is követelhet a társtulajdonostól.
Az online személyiségi jogsértések a bírói gyakorlatban
Authors: Pádár Henrietta
Published: June 2017

This essay examines the judicial practice of infringements of personality rights in the online media. The purpose is to evaluate the effectiveness of the protection of legal regulation.

The new media law that came into force in 2011 does not include specific measure for online media products, so it is up to the judicial practice to find a solution to tackle the problems brought forth by the differences of online and print press.

Being a legal area where the legal development activity of the judicial practice plays a significant role due to the broad framework of regulation, the joint interpretation of legislation and the practice is necessary to evaluate. Thus the evaluation of the effectiveness of the protection of personality rights is only possible with the joint examination of legal environment and judicial practice.

The starting point is the observation of the characteristics of online media and the comparison with print media through elements that can be relevant in a lawsuit.

The investigation of the judicial practice focuses on the infringement of personality law and the process of press correction, considering that these are the most frequently occurring legal actions in lawsuits.

This paper examines insider trading regulation regulations from the viewpoint of agency costs. An overview is given regarding the different definitions of insider trading in jurisprudence which helps establishing the essence of this behaviour. The author also aims to give an insight to the agency problem and agency costs which arise in a business organisation with separate ownership and management. Only through that can be the effects of insider trading demonstrated on agency costs. The article aims to give a balanced overview by enumerating reasons whether insider trading increases or decreases agency costs. If it raises agency costs then prohibition is justified. If it decreases agency costs, e.g. it serves as a more efficient compensation mechanism, then allowing insider trading might be more beneficial.

Achieving an estimation of viscosity in crude oil binary mixtures is often difficult because the relationship of viscosity, to the fraction of each crude oil, and many other parameters and constants is comply.  This relationship can be expressed by mathematical models with different variables. Besides the known models for predicting the viscosity of crude oil mixtures, the petroleum industry demands other models which give accurate predictions. In this work, two new empirical models have been developed for the calculation of the viscosity of binary crude oil blends. Two techniques—least square (LS) and genetic algorithm (GA)—were used to determine the parameters of the proposed models. Dynamic viscosity of 12 sets of crude oil blends at 298.15 K and 25 different shear rates were measured, resulting in 300 sets of binary data. Moreover, 700 sets of kinematic viscosity binary data were collected from literature sources and used along with 200 of the 300 sets of experimental binary data with a wide range of American Petroleum Institute (API) gravity (9.89–41.2) and viscosity (1.054–165,860 cSt) to examine existing available models as well as the newly developed models in this study. The remaining 100 experimental data points which were not used in the regression process were used for validating the models. The results in terms of the absolute average relative deviation (AARD%) were 33.546 and 14.195 for the LS method and 13.113 and 13.672 for the GA method for proposed models one and two, respectively. The results of statistical parameters based on the GA and LS methods showed that the GA is a superior method for new model parameter estimation as compared with the traditional LS technique. The GA-based models developed in this study provided the highest accuracy for viscosity calculation of the crude oil blends over all existing models in the literature.

Nigeria has abundant supplies of biomass resources and agro-forestry residues (waste), including sawdust, whose potentials are yet to be fully utilized for economic advantage. This study was undertaken to investigate the properties of paperboard briquettes produced from a mixture of shredded waste paper (pulp) and sawdust using starch as binder. The paperboard briquettes were produced manually by compressing soaked mixtures of pulp and sawdust in a wooden mould (28 cm x 28 cm x 1 cm) with a compressive load of 26 kg in the mixing ratios (by weight) 100:0, 70:30, 50:50, 70:30, and 0:100 of pulp to sawdust, respectively. The compressed mixtures were sun dried for three days to ensure proper drying and free from moisture. Density, compressive and tensile tests were carried out on the test samples. The results showed that mass and density of the paperboard increased with increased amount of the sawdust in the mixture. Test results showed that compressive strength decreases as the sawdust content increases. Sample A, which is 100% paper, had a compressive strength of 5215 kPa, while Sample E, which is 100% sawdust, had a compressive strength of 22.02 kPa. It was also observed that sample B, which is 70% pulp and 30% sawdust, had the highest tensile strength of 0.629 kPa. However, the tensile strength reduces as the sawdust ratio in the mixture increases. The tensile strength of sample E (100% sawdust) could not be determined because the sample failed to bind properly. It was concluded that paperboard briquettes can be produced using paper and sawdust, which are generally considered wastes.

Published: June 2017

A modified differential evolution algorithm (MDE) has been used for solving different process related design problems (namely calculation of the NRTL and Two-Suffix Margules activity coefficient models parameters in 20 ternary extraction systems including different ionic liquids and reactor network design problem). The obtained results, in terms of root mean square deviations (rmsd) for these models are satisfactory, with the overall values of 0.0023 and 0.0170 for 169 tie-lines for NRTL and Two-Suffix Margules models, respectively. The results showed that the MDE algorithm results in better solutions compared to the previous work based on genetic algorithm (GA) for correlating liquid-liquid equilibrium (LLE) data in these systems. MDE also outperformed DE algorithm when tested on reactor network design problem with respect to convergence and speed.

Published: June 2017

Many regions in the world have recently experienced more frequent and intensive disasters such as flash floods and persistent droughts. The Sultanate of Oman is no exception to this. We analyzed twodecade long daily precipitation records in three major cities, namely, Sohar, Muscat and Salalah, mainly focusing on extremes. A set of climate indices defined in the RClimDex software package was used. Moreover, annual maximum 1-day precipitations in three study areas were analyzed using the Generalized Extreme Value (GEV) distribution function.  Results showed significant changes in the precipitation regime in recent years. The annual total precipitation in Sohar and Salalah decreased, while that in Muscat shows statistically week increasing trend. However, all indices analyzed indicate enhanced extreme precipitation toward 2010 in Muscat and Salalah. As a result, the contribution from extreme events to the annual total rainfall steadily increases in both study areas. A clear conclusion could not be made based on selected indices for Sohar due to consistent drier years occurred from 1999 to 2005. Frequency analysis indicates that the annual the maximum 1-day rainfall estimated in Sohar and Muscat for 5 and 10 year return periods are approximately same (70 mm/day and 108 mm/day, respectively) but about two-fold greater than that in Salalah (29 mm/day and 60 mm/day, respectively).
Performance of Cement-Based Patch Repair Materials in Plain and Reinforced Concrete Members
Authors: Al-Saidy A.H.
Published: June 2017

Structural elements such as beams, slabs, and columns may require strengthening or repair during their service life. Different repair materials (RMs) are available and it is usually difficult to choose the best ones, especially when considering the cost of such materials. This paper presents the results of an experimental investigation of patch RMs on plain concrete prisms as well as on reinforced concrete beams. Three cement-based RMs available in the market with different mechanical properties and an ordinary Portland cement (OPC) mix produced in the lab were used in the study. Damage was induced in prisms/beams and then repaired using different materials. The experimental work included assessment of the flexural strength of damaged/repaired plain concrete prisms; slant shear (bond) strength between the concrete and the RM; axial strength of damaged/repaired plain concrete prisms and bond of the repair materials in damaged/repaired reinforced concrete beams loaded to failure. The test results showed that all RMs performed well in restoring the strength of damaged plain concrete. Compatibility of the RMs with substrate concrete was found to be more important in the behavior than superior mechanical properties of the RMs. No difference was noted in the behavior between the RMs in repairing reinforced concrete beams at the tension side.
Reactive Power based Model Reference Neural Learning Adaptive System for Speed Estimation in Sensor-less Induction Motor Drives

Published: June 2017

In this paper, a novel reactive power based model reference neural learning adaptive system (RP-MRNLAS) is proposed. The model reference adaptive system (MRAS) based speed estimation is one of the most popular methods used for sensor-less controlled induction motor drives. In conventional MRAS, the error adaptation is done using a Proportional-integral-(PI). The non-linear mapping capability of a neural network (NN) and the powerful learning algorithms have increased the applications of NN in power electronics and drives. Thus, a neural learning algorithm is used for the adaptation mechanism in MRAS and is often referred to as a model reference neural learning adaptive system (MRNLAS). In MRNLAS, the error between the reference and neural learning adaptive models is back propagated to adjust the weights of the neural network for rotor speed estimation. The two different methods of MRNLAS are flux based (RF-MRNLAS) and reactive power based (RP-MRNLAS). The reactive power- based methods are simple and free from integral equations as compared to flux based methods. The advantage of the reactive power based method and the NN learning algorithms are exploited in this work to yield a RPMRNLAS. The performance of the proposed RP-MRNLAS is analyzed extensively. The proposed RP-MRNLAS is compared in terms of accuracy and integrator drift problems with popular rotor flux-based MRNLAS for the same system and validated through Matlab/Simulink. The superiority of the RP- MRNLAS technique is demonstrated
