Valorization of an Industrial Organosolv-Sugarcane Bagasse Lignin: Characterization and Use as a Matrix in Biobased Composites Reinforced With Sisal Fibers

In the present study, the main focus was the characterization and application of the by-product lignin isolated through an industrial organosolv acid hydrolysis process from sugarcane bagasse, aiming at the production of bioethanol. The sugarcane lignin was characterized and used to prepare phenolic-type resins. The analysis confirmed that the industrial sugarcane lignin is of HGS type, with a high proportion of the less substituted aromatic ring p-hydroxyphenyl units, which favors further reaction with formaldehyde. The lignin-formaldehyde resins were used to produce biobased composites reinforced with different proportions of randomly distributed sisal fibers. The presence of lignin moieties in both the fiber and matrix increases their mutual affinity, as confirmed by SEM images, which showed good adhesion at the biocomposite fiber/matrix interface. This in turn allowed good load transference from the matrix to the fiber, leading to biobased composites with good impact strength (near 500 J m(-1) for a 40 wt% sisal fiber-reinforced composite). The study demonstrates that sugarcane bagasse lignin obtained from a bioethanol plant can be used without excessive purification in the preparation of lignocellulosic fiber-reinforced biobased composites displaying high mechanical properties.

Sixteen compounds were identified, representing 91.4% of the total oil. The major components were safrole (58.4%), dodecanoic acid (13.7%) and alpha-terpineol (8.4%). Oxygenated monoterpenoids were the main group of compounds.

ANALYSIS & STUDY OF AI TECHNIQUES FORAUTOMATIC CONDITION MONITORING OFRAILWAY TRACK INFRASTRUCTURE : Artificial Intelligence Techniques

Since the last decade the problem of surface inspection has been receiving great attention from the scientific community, the quality control and the maintenance of products are key points in several industrial applications.The railway associations spent much money to check the railway infrastructure. The railway infrastructure is a particular field in which the periodical surface inspection can help the operator to prevent critical situations. The maintenance and monitoring of this infrastructure is an important aspect for railway association.That is why the surface inspection of railway also makes importance to the railroad authority to investigate track components, identify problems and finding out the way that how to solve these problems. In railway industry, usually the problems find in railway sleepers, overhead, fastener, rail head, switching and crossing and in ballast section as well. In this thesis work, I have reviewed some research papers based on AI techniques together with NDT techniques which are able to collect data from the test object without making any damage. The research works which I have reviewed and demonstrated that by adopting the AI based system, it is almost possible to solve all the problems and this system is very much reliable and efficient for diagnose problems of this transportation domain. I have reviewed solutions provided by different companies based on AI techniques, their products and reviewed some white papers provided by some of those companies. AI based techniques likemachine vision, stereo vision, laser based techniques and neural network are used in most cases to solve the problems which are performed by the railway engineers.The problems in railway handled by the AI based techniques performed by NDT approach which is a very broad, interdisciplinary field that plays a critical role in assuring that structural components and systems perform their function in a reliable and cost effective fashion. The NDT approach ensures the uniformity, quality and serviceability of materials without causing any damage of that materials is being tested. This testing methods use some way to test product like, Visual and Optical testing, Radiography, Magnetic particle testing, Ultrasonic testing, Penetrate testing, electro mechanic testing and acoustic emission testing etc. The inspection procedure has done periodically because of better maintenance. This inspection procedure done by the railway engineers manually with the aid of AI based techniques.The main idea of thesis work is to demonstrate how the problems can be reduced of thistransportation area based on the works done by different researchers and companies. And I have also provided some ideas and comments according to those works and trying to provide some proposal to use better inspection method where it is needed.The scope of this thesis work is automatic interpretation of data from NDT, with the goal of detecting flaws accurately and efficiently. AI techniques such as neural networks, machine vision, knowledge-based systems and fuzzy logic were applied to a wide spectrum of problems in this area. Another scope is to provide an insight into possible research methods concerning railway sleeper, fastener, ballast and overhead inspection by automatic interpretation of data.In this thesis work, I have discussed about problems which are arise in railway sleepers,fastener, and overhead and ballasted track. For this reason I have reviewed some research papers related with these areas and demonstrated how their systems works and the results of those systems. After all the demonstrations were taking place of the advantages of using AI techniques in contrast with those manual systems exist previously.This work aims to summarize the findings of a large number of research papers deploying artificial intelligence (AI) techniques for the automatic interpretation of data from nondestructive testing (NDT). Problems in rail transport domain are mainly discussed in this work. The overall work of this paper goes to the inspection of railway sleepers, fastener, ballast and overhead.

Defining Relevant Product Markets for Pharmaceuticals

To identify the relevant product markets for Swedish pharmaceuticals, a spatial econometrics approach is employed. First, we calculate Moran’s Is for different market definitions and then we use a spatial Durbin model to determine the effect of price changes on quantity sold off own and competing products. As expected, the results show that competition is strongest between close substitutes; however, the relevant product markets for Swedish pharmaceuticals extend beyond close substitutes down to products included in the same class on the four-digit level of the Anatomic Therapeutic Chemical system as defined by the World Health Organization. The spatial regression model further indicates that increases in the price of a product significantly lower the quantity sold of that product and in the same time increase the quantity sold of competing products. For close substitutes (products belonging to the same class on the seven-digit level of the Anatomic Therapeutic Chemical system), as well as for products that, without being close substitutes, belong to the same therapeutic/pharmacological/chemical subgroup (the same class on the five-digit level of the Anatomic Therapeutic Chemical system), a significant change towards increased competition is also visible after 1 July 2009 when the latest policy changes with regards to pharmaceuticals have been implemented in Sweden.

Extended local labor markets due to high speed trains : Visualization of estimations in the Swedish national travel demand forecasting tool, SAMPERS

Wider economic benefits resulting from extended geographical mobility is one argument for investments in high-speed rail. More specifically, the argument for high-speed trains in Sweden has been that they can help to further spatially extend labor market regions which in turn has a positive effect on growth and development. In this paper the aim is to cartographically visualize the potential size of the labor markets in areas that could be affected by possible future high-speed trains. The visualization is based on the forecasts of labor mobility with public transport made by the Swedish national mobility transport forecasting tool, SAMPERS, for two alternative high-speed rail scenarios. The analysis, not surprisingly, suggests that the largest impact of high-speed trains results in the area where the future high speed rail tracks are planned to be built. This expected effect on local labor market regions of high-speed trains could mean that possible regional economic development effects also are to be expected in this area. However, the results, in general, from the SAMPERS forecasts indicaterelatively small increases in local labor market potentials.

Predicting entry of Swedish wholesale firms into local markets

Applying microeconomic theory, we develop a forecasting model for firm entry into local markets and test this model using data from the Swedish wholesale industry. The empirical analysis is based on directly estimating the profit function of wholesale firms. As in previous entry studies, profits are assumed to depend on firm- and location-specific factors,and the profit equation is estimated using panel data econometric techniques. Using the residuals from the profit equation estimations, we identify local markets in Sweden where firm profits are abnormally high given the level of all independent variables included in the profit function. From microeconomic theory, we then know that these local markets should have higher net entry than other markets, all else being equal, and we investigate this in a second step,also using a panel data econometric model. The results of estimating the net-entry equation indicate that four of five estimated models have more net entry in high-return municipalities, but the estimated parameter is only statistically significant at conventional levels in one of our estimated models.

Design industrial como fonte de vantagem estratégica: estudo de caso na indústria moveleira

This research was based on the lack of academic investigations which recognize industrial design as an strategic advantages source. It was chosen to adopt a wide approach, not common in administration researches, through which aspects frequently ignored by most of the strategy and marketing literature could be recognized. The investigation took place at a big brazilian company, from the furniture industry, more specifically from the office furniture segment. Two product development cases were selected: one of them classified by the company as an example of success and the other as a failure case. It is an exploratory study. Some important topics were identified, and they may be developed in future researches: the existence of intra-organizational conflicts between marketing and engineering; the big companies' power over market configuration, and the State influence over local markets dinamics.

A competitividade internacional de firmas transnacionais na nova geografia econômica das nações em processo de integração político-econômica regional: uma análise longitudinal de empresas globais em macrorregiões supranacionais

Devido ao fenômeno da globalização, alguns aspectos em Economia Internacional e Política têm sido amplamente debatidos entre os estudiosos de Negócios Internacionais, dada a extensão do seu impacto sobre a competitividade operacional e estratégica das empresas multinacionais. Em conjunto com a realidade mais regional da maioria dos acordos preferenciais de comércio e de investimentos – que promovem uma integração regional mais profunda dos mercados, ao contrário do teórico mercado "global" – as abordagens teóricas mais globalizantes em estratégia de negócios internacionais têm sido mais questionadas. Enquanto alguns estudiosos, como Pankaj Ghemawat, (2007), propõem abordagens para a chamada "semi-globalização"; outros, por exemplo, com Alan Rugman e Alain Verbeke (inter alias 2004, 2007), por outro lado, defendem abordagens regionalistas mais restritas em negócios internacionais e estratégia de empresas internacionais. Tais posições sobre o desempenho das empresas transnacionais, no entanto, não foram amplamente testadas, deixando, assim, outras questões relevantes sem soluções. Assim sendo, identificou-se um espaço na literatura quanto à questão de as regiões – em vez de países individualmente considerados – serem ou não relevantes ao desempenho global das empresas multinacionais e em que medida. Nesse sentido, foi utilizada uma metodologia quantitativa longitudinal a fim de avaliar a evidência histórica da repercussão de presença em regiões selecionadas e/ou países sobre o desempenho das empresas transnacionais. Foram coletados dados no Compustat Global (2009) com vistas a uma análise econométrica de dados em painel. Nossos resultados consistem, brevemente, em três aspectos. Em primeiro lugar, quando ambas as variáveis (país e região) são simultaneamente consideradas influentes sobre o desempenho, existe significância estatística. Em segundo lugar, ao contrastar ambas as variáveis (país e região) entre si, em relação ao maior nível de impacto no desempenho, ainda que tenhamos encontrado relevância estatística para os países individualmente considerados, suspeitou-se de algum problema nos dados brutos. Em terceiro lugar, ao assumir uma correlação positiva entre o desempenho da empresa multinacional e do número de regiões geográficas onde essas corporações possuem operações significativas, foi encontrada significância estatística. Nossa conclusão, portanto, consiste no fato de que, dado que a maioria dos países são signatários de pelo menos um acordo de integração regional, as regiões devem ser o foco principal dos negócios internacionais e estratégia corporativa internacional, tanto nos propósitos teóricos (tendo em vista as conclusões desta pesquisa e a literatura sobre o assunto), quanto nos aspectos práticos (em vez de da customização da gestão e da estratégia para cada país individual).

Biodiesel do dendê: um estudo de viabilidade econômico financeira no Estado do Pará

O objetivo deste estudo é analisar três modelos de operação de uma usina de extração de óleo de palma, de óleo de palmiste, e de biodiesel, respectivamente, em conjunto com a produção de dendê pela agricultura familiar, visando o fornecimento exclusivo de matéria-prima para a indústria através da parceria com Programa Nacional da Agricultura Familiar. O projeto consiste na construção de uma usina de grande porte, a partir de investimentos de fontes públicas e privadas voltados à construção do complexo industrial e ao financiamento da implantação do cultivo de dendê pelos agricultores. Foram construídos quatro cenários, onde foram analisados os indicadores de performance econômico-financeira de avaliação do arranjo produtivo da indústria e da parte agrícola. Esses cenários visam a tomada de decisões de investimentos, através da utilização dos indicadores econômico-financeiros clássicos para avaliação da viabilidade do dendê como matéria-prima para o complexo industrial da usina. Entre os indicadores utilizados neste trabalho podemos citar como principais: o VPL (Valor Presente Líquido) e a TIR (Taxa Interna de Retorno), e indicadores secundários utilizados como suporte para as análises, tais como Payback Descontado, TIRM (Taxa Interna de Retorno Modificada), dentre outros. Além de indicadores sociais, como geração de renda para as famílias de agricultores, com o objetivo principal de criar valor monetário, gerar emprego e renda e pagar os recursos dos investidores púbicos. A implantação do dendezal está fundamentada no Zoneamento Agroecológico do dendê e será executada em áreas degradas por pastagens para garantir a sustentabilidade, contribuir para a recuperação ambiental através do sequestro de carbono e diminuir a pressão sobre as florestas nativas. Consequentemente, espera-se que o projeto contribua para evitar o avanço do desmatamento na região da Amazônia legal. Para tanto, foram realizadas visitas às plantações de dendê e à usina da Biopalma. Também foram realizadas visitas à Embrapa Ocidental na cidade de Manaus e Embrapa na Cidade de Campinas. Foi proposto um modelo de análise econômica financeira baseado em implantação de uma usina de grande porte para a produção de Biodiesel no Estado do Pará. O estudo apresentou, dentre suas limitações, o fato de ser complexo e amplo. A inexistência de projetos de usina grande envergadura totalmente implantados e funcionando com emprego de tecnologia e capital intensivo, como também a impossibilidade de se realizar esta pesquisa de amplo espectro sem um número consideravelmente maior de organizações envolvidas. Como resultado, os indicadores economicos analisados mostram que há viabilidade do projeto em três dos quatro cenários construídos, demonstrando que o capital dos investidores públicos, privados e do agricultor familiar serão remunerados utilizando às taxas de juros, prazos, condições do mercado de capitais. O objetivo é atrair investimentos para a produção de biodiesel, implantação de empreendimentos agrícolas, indústriais, geração emprego e renda para Agricultura Familiar na cadeia produtiva do dendê.

Product placement in movies: a cross cultural study between Brazil and the USA

The broader objective of this study undertaking can briefly be articulated in particulate aims as follows: to measure the attitudes of consumers regarding the brand displayed by this strategy as well as to highlight recall, recognition and purchase intentions generated by product placement on consumers. In addition, check the differences and similarities between the behavior of Brazilian and American consumers caused by the influence of product placements. The study was undertaken targeting consumer audience in Brazil and the U.S. A rang3 modeling set ups were performed in order to realign study instruments and hypothesis towards the research objectives. This study gave focus on the following hypothesized models. H1: Consumers / Participants who viewed the brands / products in the movie have a higher brand / product recall compared to the consumers / participants who did not view the brands / products in the movie. H2: US Consumers / Participants are able to recognize and recall brands / products which appear in the background of the movie than Brazil. H3: Consumers / participants from USA are more accepting of product placements compared to their counterparts in Brazil. H4: There are discernible similarities in consumer / participant brand attitudes and purchase intentions in consumers / participants from USA and Brazil in spite of the fact that their country of origin is different. Cronbach’s Alpha Coefficient ensured the reliability of survey instruments. The study involved the use of the Structural Equation Modeling (SEM) for the hypothesis testing. This study used the Confirmatory Factor Analysis (CFA) to assess both the convergent and discriminant validities instead of using the Exploratory Factor Analysis (EFA) or the Principal Component Analysis (PCA). This reinforced for the use of the regression Chi Square and T statistical tests in further. Only hypothesis H3 was rejected, the rest were not. T test provided insight findings on specific subgroup significant differences. In the SEM testing, the error variance for product placement attitudes was negative for both the groups. On this The Heywood Case came in handy to fix negative values. The researcher used both quantitative and qualitative approach where closed ended questionnaires and interviews respectively were used to collect primary data. The results were additionally provided with tabulations. It can be concluded that, product placement varies markedly in the U.S. from Brazil based on the influence a range of factors provided in the study. However, there are elements of convergence probably driven by the convergence in technology. In order, product placement to become more competitive in the promotional marketing, there will be the need for researchers to extend focus from the traditional variables and add knowledge on the conventional marketplace factors that is the sell-ability of the product placement technologies and strategies.

The influence of the supply chain agents on the new product development's performance: an analysis based on the multi-group moderation

Este estudo buscou verificar a influencia dos agentes da cadeia de suprimentos no desempenho do desenvolvimento de novos produtos quando os agentes são analisados em conjunto. A motivação desta pesquisa veio de estudos que alertaram para a consideração da integração da cadeia de suprimentos como um constructo multidimensional, englobando o envolvimento da manufatura, fornecedores e clientes no desenvolvimento de novos produtos; e devido à falta de informação sobre as influencias individuais destes agentes no desenvolvimento de novos produtos. Sob essas considerações, buscou-se construir um modelo analítico baseado na Teoria do Capital Social e Capacidade Absortiva, construir hipóteses a partir da revisão da literatura e conectar constructos como cooperação, envolvimento do fornecedor no desenvolvimento de novos produtos (DNP), envolvimento do cliente no DNP, envolvimento da manufatura no DNP, antecipação de novas tecnologias, melhoria contínua, desempenho operacional do DNP, desempenho de mercado do NPD e desempenho de negócio do DNP. Para testar as hipóteses foram consideradas três variáveis moderadoras, tais como turbulência ambiental (baixa, média e alta), indústria (eletrônicos, maquinários e equipamentos de transporte) e localização (América, Europa e Ásia). Para testar o modelo foram usados dados do projeto High Performance Manufacturing que contém 339 empresas das indústrias de eletrônicos, maquinários e equipamentos de transporte, localizadas em onze países. As hipóteses foram testadas por meio da Análise Fatorial Confirmatória (AFC) incluindo a moderação muti-grupo para as três variáveis moderadoras mencionadas anteriormente. Os principais resultados apontaram que as hipóteses relacionadas com cooperação foram confirmadas em ambientes de média turbulência, enquanto as hipóteses relacionadas ao desempenho no DNP foram confirmadas em ambientes de baixa turbulência ambiental e em países asiáticos. Adicionalmente, sob as mesmas condições, fornecedores, clientes e manufatura influenciam diferentemente no desempenho de novos produtos. Assim, o envolvimento de fornecedores influencia diretamente no desempenho operacional e indiretamente no desempenho de mercado e de negócio em baixos níveis de turbulência ambiental, na indústria de equipamentos de transporte em países da Americanos e Europeus. De igual forma, o envolvimento do cliente influenciou diretamente no desempenho operacional e indiretamente no desempenho de mercado e do negócio em médio nível de turbulência ambiental, na indústria de maquinários e em países Asiáticos. Fornecedores e clientes não influenciam diretamente no desempenho de mercado e do negócio e não influenciam indiretamente no desempenho operacional. O envolvimento da manufatura não influenciou nenhum tipo de desempenho do desenvolvimento de novos produtos em todos os cenários testados.

Understanding e-government technology transfer: evidence from the transfer of a patent management system from EPO to INPI

Drawing upon Brazilian experience, this research explores some of the key issues to be addressed in using e-government technical cooperation designed to enhance service provision of Patent Offices in developing countries. While the development of software applications is often seen merely as a technical engineering exercise, localization and adaptation are context bounded matters that are characterized by many entanglements of human and non-humans. In this work, technical, legal and policy implications of technical cooperation are also discussed in a complex and dynamic implementation environment characterized by the influence of powerful hidden agendas associated with the arena of intellectual property (IP), which are shaped by recent technological, economic and social developments in our current knowledge-based economy. This research employs two different theoretical lenses to examine the same case, which consists of transfer of a Patent Management System (PMS) from the European Patent Office (EPO) to the Brazilian Patent Office that is locally named ‘Instituto Nacional da Propriedade Industrial’ (INPI). Fundamentally, we have opted for a multi-paper thesis comprising an introduction, three scientific articles and a concluding chapter that discusses and compares the insights obtained from each article. The first article is dedicated to present an extensive literature review on e-government and technology transfer. This review allowed the proposition on an integrative meta-model of e-government technology transfer, which is named E-government Transfer Model (ETM). Subsequently, in the second article, we present Actor-Network Theory (ANT) as a framework for understanding the processes of transferring e-government technologies from Patent Offices in developed countries to Patent Offices in developing countries. Overall, ANT is seen as having a potentially wide area of application and being a promising theoretical vehicle in IS research to carry out a social analysis of messy and heterogeneous processes that drive technical change. Drawing particularly on the works of Bruno Latour, Michel Callon and John Law, this work applies this theory to a longitudinal study of the management information systems supporting the Brazilian Patent Office restructuration plan that involved the implementation of a European Patent Management System in Brazil. Based upon the ANT elements, we follow the actors to identify and understand patterns of group formation associated with the technical cooperation between the Brazilian Patent Office (INPI) and the European Patent Office (EPO). Therefore, this research explores the intricate relationships and interactions between human and non-human actors in their attempts to construct various network alliances, thereby demonstrating that technologies embodies compromise. Finally, the third article applies ETM model as a heuristic frame to examine the same case previously studied from an ANT perspective. We have found evidence that ETM has strong heuristic qualities that can guide practitioners who are engaged in the transfer of e-government systems from developed to developing countries. The successful implementation of e-government projects in developing countries is important to stimulate economic growth and, as a result, we need to understand the processes through which such projects are being implemented and succeed. Here, we attempt to improve understanding on the development and stabilization of a complex social-technical system in the arena of intellectual property. Our preliminary findings suggest that e-government technology transfer is an inherently political process and that successful outcomes require continuous incremental actions and improvisations to address the ongoing issues as they emerge.
