Da bancada ao Bureau: análise do desenvolvimento da biotecnologia no Nordeste Brasileiro sob o enfoque de Sistema Regional de Inovação

The starting point of the present work consisted of investigating the development of biotechnology in the Northeast region of Brazil from the perspective of a Regional Innovation System (RIS). The theoretical framework adopted relied on the approaches and concepts presented by the Neo-Schumpeterian perspective. This framework was chosen because, by means of the Innovation System concept, this literature allows us to analyze the relationships and configurations of actors, as well as the role of the state and of social, science and technology, and economic policies in the studied region. The analysis considered four selected dimensions: physical infrastructure, human capital, scientific production, and funding. These variables were chosen because they allow us to verify the possibilities and limitations of developing a biotechnology RIS in the Northeast of Brazil, and these elements would help in answering the question behind this dissertation. The location of the physical infrastructure was determined by means of bibliographic and documental research and interviews with heads of institutions that do biotechnology research. Regarding human capital, the analysis focused on resource training in biotechnology, highlighting graduate courses and research groups in the area. To measure knowledge production, we delimited scientific collaboration among researchers in the field of biotechnology as the focus of this category. For the funding dimension, information was gathered from reports available at the websites of national and state funding agencies. The data was analyzed through method triangulation, involving quantitative and qualitative research stages. To back the analyses, we revisited the integration policies in the area of Science, Technology and Innovation. Our analysis has shown that these policies play a crucial role in the development of biotechnology in the region being studied. The data revealed that the physical infrastructure is concentrated in only three states (Bahia, Ceará, and Pernambuco). In this regard, the Northeast Biotechnology Network (Renorbio) stands out as a strategic actor, enabling states with poor infrastructure to develop research through partnerships with institutions located in another state. We have also verified that the practices involving human resource training and knowledge production are factors that enable the emergence of a regional system for biotechnology in the studied region. As limitations, we have verified the low immersion level of regional actors, the heterogeneity of socioeconomic indicators, the lack of financial resources, and a low innovation culture in the business sector. Overall, we have concluded that the development of a Regional Innovation System in Biotechnology, based on the current regional dynamics, depends on an effective change in the behavior of the social agents involved, both in the national and regional dimensions as well as in the public and private spheres

Desenvolvimento de um protótipo para análise dinâmica da dureza de superfícies metálicas

In this paper we developed a prototype for dynamic and quantitative analysis of the hardness of metal surfaces by penetration tests. It consists of a micro-indenter which is driven by a gear system driven by three-rectified. The sample to be tested is placed on a table that contains a load cell that measures the deformation in the sample during the penetration of micro-indenter. With this prototype it is possible to measure the elastic deformation of the material obtained by calculating the depth of penetration in the sample from the difference of turns between the start of load application to the application of the load test and return the indenter until the complete termination of load application. To determine the hardness was used to measure the depth of plastic deformation. We used 7 types of steel trade to test the apparatus. There was a dispersion of less than 10% for five measurements made on each sample and a good agreement with the values of firmness provided by the manufacturers.

Estudo exploratório das percepções de irmãos e figuras parentais sobre o comportamento lúdico de pessoas com perturbação do espectro do autismo

Artigo 1: As pessoas com Perturbação do Espectro do Autismo (PEA) têm dificuldades sociais que impactam o desenvolvimento do comportamento lúdico (Naber et al., 2008). Os profissionais atentam pouco ao papel dos irmãos na família mas esta realidade pode influenciar a relação fraterna e carece de investigação. Este estudo analisou as percepções de 11 irmãos (5-12 anos) com desenvolvimento típico de pessoas com PEA (≥3 anos) sobre a interacção lúdica e identificou as suas necessidades a respeito da mesma. Foram conduzidas duas entrevistas: a Entrevista da Percepção dos Irmãos Acerca da Interacção Lúdica (EPI) junto dos irmãos para obter as percepções e a Entrevista para Recolha de Dados dos Participantes (ERDP) junto de uma figura parental para recolher dados sociodemográficos; os instrumentos foram elaborados pela equipa de investigação e submetidos a um estudo-piloto e validação por peritagem. Os dados sociodemográficos foram tratados no SPSS® 22 e as percepções foram submetidas a análise de conteúdo no MAXqda® 10 e sujeitas a validação. Os resultados obtidos indicam que as percepções sobre a interacção lúdica são predominantemente positivas e parecem conduzir ao interesse em aprender para satisfazer as necessidades existentes. As expectativas dos irmãos e a funcionalidade da comunicação constituem factores emergentes, bem como a ligação entre figuras e conteúdos de interesse na aprendizagem. Artigo 2: A relação fraterna exerce influência no sistema familiar e por isso deve ser feito um investimento no seu estudo. Entre pessoas com Perturbação do Espectro do Autismo (PEA) e os seus irmãos com desenvolvimento típico a interacção social pode apresentar desafios acrescidos e causar impacto na interacção lúdica. Este trabalho objectivou comparar as percepções de 11 irmãos e pais de pessoas com PEA (≥3 anos) acerca da interacção lúdica e eventuais necessidades para a melhorar, procurando diferenças e explorando factores emergentes. Foram elaboradas três entrevistas semi-estruturadas, testadas num estudo-piloto e submetidas à validação por expertise. Os irmãos responderam a uma entrevista de 31 questões referente às suas percepções acerca de tópicos relevantes na literatura. Os pais participaram numa entrevista com 35 questões com o mesmo objectivo e uma entrevista de 39 questões para recolher dados sociodemográficos. Os dados sociodemográficos foram analisados descritivamente e as percepções foram submetidas a análise de conteúdo. Os resultados foram interpretados em função da convergência e divergência dos relatos dos dois grupos de participantes e reforçam que existe uma tendência de divergência nas percepções dos dois grupos. As diferenças encontradas entre os grupos apontam para vários aspectos que devem ser tidos em conta na intervenção psicomotora junto das famílias de pessoas com PEA.

Contributos da avaliação exterrna em dois agrupamentos do Alentejo

O presente trabalho de investigação teve como ponto de partida a questão "O contrato de autonomia representa ou não uma mais-valia no processo de desenvolvimento da organização escola?'; assumindo esta o eixo central deste trabalho: "Contributos da Avaliação Externa em dois Agrupamentos do Alentejo'’. Neste sentido, foram definidas algumas hipóteses de trabalho: em termos de visão/estratégia procurámos verificar se uma liderança forte, com objetivos definidos e hierarquizados, apresentando uma nova forma de gerir o currículo, provocará na escola uma maior aptidão para atingir as metas estabelecidas; quanto à motivação/empenho, se os órgãos de gestão da escola assumirem o processo de decisão e se responsabilizarem pelo mesmo, este facto constituirá uma mais-valia para a escola de modo a alcançar as metas propostas; no que concerne ao campo da inovação, procurámos constatar se a escola procura novos caminhos, novas soluções, facto esse que motivará o seu reconhecimento pela excelência; por último as parcerias e projetos, ou seja verificar se a existência de parcerias cativas e outras formas de associação favorecem o projeto de autonomia da escola. No que concerne ao estudo empírico, optámos por uma metodologia que privilegiou o estudo qualitativo dos dados apurados. Após apresentação dos dados recolhidos, da respetiva análise e interpretação, emitimos as nossas conclusões, entre as quais o facto da avaliação externa ter sido um facto de mudança na vida dos dois agrupamentos. Quer seja como fator de mudança e motivação para o crescimento do agrupamento como um todo, quer seja como fator de união de um agrupamento, trazendo à luz do dia as virtudes e os constrangimentos, encontrando soluções e caminhos através de um projeto de autonomia que se tornou um símbolo de todos. ABSTRACT: This work of investigation had as a starting point whether the question "The autonomy of schools becomes or not a better value in the development of the school organization?" being in the central issue of this thesis - "The contribution of externa! evaluation in two school groups from Alentejo". ln this sense, some hypothesis were defined: concerning vision/strategy we dryed to verify if a strong leadership with defined and hierarchyed objectives demonstrating new ways of managing the curriculum makes the school more capable of reaching the pre-established goals; concerning motivation/commitment, if the school management assumes the process of decision and take responsibility for it, will this be a best value for the school, in order to achieve their goal; relating to innovation, we try to establish if the school demands new ways, new solutions, bringing recognition "par excellence"; finally partnerships and projects, which intends to verify if the existence of active partnerships and others forms of association, would benefit the autonomy of the school. ln what concerns the empirical study we decided to choose a methodology which benefited the qualitative of gathered data. After the presentation of the collected results, its analysis and interpretation, we came to the conclusion, among others, that the external evaluation had been a drive for change in the two school groups. Whether as a factor of change and motivation for the development of the whole group, as well as a factor of union, bringing up the virtues and the mistakes, finding solutions and new ways through a project of autonomy which became a reference for everyone.

Análise comparativa entre as propriedades do gesso obtido de rejeito da produção de sal e gesso comerciais

The environmental impacts, caused by the solid residues generation, are an often quoted concern nowadays. Some of these residues, which are originated from different human activities, can be fully reused, reducing the effects of the poor waste management on the environment. During the salt production process, the first formed crystals are discarded as industrial waste. This is mainly made of gypsum that is a calcium sulfate dihydrate (CaSO4.2H2O). The gypsum in question may go through a calcination process due to the plaster (CaSO4.0,5H2O) production and then the application on the cement industry. Considering the necessity of development and application for these industrial wastes, this paper aims to analyze the plaster, called Salgesso, from the gypsum that was generated during the salt production, and its use viability on the civil construction industry in order to create environmental and economical benefits. For characterization, the following experiments were performed: X-ray Fluorescence (XRF), X-ray Diffraction (XRD), thermal analysis (TG/DTG) and Scanning Electron Microscopy (SEM) with EDS. The following tests were also performed to obtain the mechanical characteristics: Thinness Modulus, Unit Mass, Setting Time and Compressive Resistance. Three commercial plasters used on civil construction were taken as references. All of these tests were performed according to the current standards. It was noticed that although there were some conflicting findings between the salt and commercial plasters in all of the studied properties, the Salgesso has its values within the standard limits. However, there is the possibility to improve them by doing a more effective calcination process. Three commercial plasters, used in construction, were used as reference material. All tests were performed according to standards in force. It was observed that although some tests present conflicting findings between the salt and gypsum plasters commercial properties in all of the studied Salgesso have values within the limits imposed by the standard, but can be improved simply by calcination process more effective

Desenvolvimento de um sistema Inteligente para a análise de cartas dinamométricas no método de elevação por bombeio mecânico

The artificial lifting of oil is needed when the pressure of the reservoir is not high enough so that the fluid contained in it can reach the surface spontaneously. Thus the increase in energy supplies artificial or additional fluid integral to the well to come to the surface. The rod pump is the artificial lift method most used in the world and the dynamometer card (surface and down-hole) is the best tool for the analysis of a well equipped with such method. A computational method using Artificial Neural Networks MLP was and developed using pre-established patterns, based on its geometry, the downhole card are used for training the network and then the network provides the knowledge for classification of new cards, allows the fails diagnose in the system and operation conditions of the lifting system. These routines could be integrated to a supervisory system that collects the cards to be analyzed

Uma metodologia para a análise do desempenho sustentável dos postos de revenda de combustível na cidade de Natal/RN, com o uso de data envelopment analysis-DEA

The increasing use of fossil fuels in line with cities demographic explosion carries out to huge environmental impact in society. For mitigate these social impacts, regulatory requirements have positively influenced the environmental consciousness of society, as well as, the strategic behavior of businesses. Along with this environmental awareness, the regulatory organs have conquered and formulated new laws to control potentially polluting activities, mostly in the gas stations sector. Seeking for increasing market competitiveness, this sector needs to quickly respond to internal and external pressures, adapting to the new standards required in a strategic way to get the Green Badge . Gas stations have incorporated new strategies to attract and retain new customers whom present increasingly social demand. In the social dimension, these projects help the local economy by generating jobs and income distribution. In this survey, the present research aims to align the social, economic and environmental dimensions to set the sustainable performance indicators at Gas Stations sector in the city of Natal/RN. The Sustainable Balanced Scorecard (SBSC) framework was create with a set of indicators for mapping the production process of gas stations. This mapping aimed at identifying operational inefficiencies through multidimensional indicators. To carry out this research, was developed a system for evaluating the sustainability performance with application of Data Envelopment Analysis (DEA) through a quantitative method approach to detect system s efficiency level. In order to understand the systemic complexity, sub organizational processes were analyzed by the technique Network Data Envelopment Analysis (NDEA) figuring their micro activities to identify and diagnose the real causes of overall inefficiency. The sample size comprised 33 Gas stations and the conceptual model included 15 indicators distributed in the three dimensions of sustainability: social, environmental and economic. These three dimensions were measured by means of classical models DEA-CCR input oriented. To unify performance score of individual dimensions, was designed a unique grouping index based upon two means: arithmetic and weighted. After this, another analysis was performed to measure the four perspectives of SBSC: learning and growth, internal processes, customers, and financial, unifying, by averaging the performance scores. NDEA results showed that no company was assessed with excellence in sustainability performance. Some NDEA higher efficiency Gas Stations proved to be inefficient under certain perspectives of SBSC. In the sequence, a comparative sustainable performance and assessment analyzes among the gas station was done, enabling entrepreneurs evaluate their performance in the market competitors. Diagnoses were also obtained to support the decision making of entrepreneurs in improving the management of organizational resources and promote guidelines the regulators. Finally, the average index of sustainable performance was 69.42%, representing the efforts of the environmental suitability of the Gas station. This results point out a significant awareness of this segment, but it still needs further action to enhance sustainability in the long term

Desenvolvimento de metodologias analíticas alternativas por cromatografia gasosa para análise de biodiesel

Since the beginning of the National Program for Production and Use of Biodiesel in Brazil, in 2004, different raw materials were evaluated for biodiesel production, trying to combine the agricultural diversity of the country to the desire to reduce production coasts. To determine the chemical composition of biodiesel produced from common vegetables oils, international methods have been used widely in Brazil. However, for analyzing biodiesel samples produced from some alternative raw materials analytical problems have been detected. That was the case of biodiesel from castor oil. Due the need to overcome these problems, new methodologies were developed using different chromatographic columns, standards and quantitative methods. The priority was simplifying the equipment configuration, realizing faster analyses, reducing the costs and facilitating the routine of biodiesel research and production laboratories. For quantifying free glycerin, the ethylene glycol was used in instead of 1,2,4-butanetriol, without loss of quality results. The ethylene glycol is a cheaper and easier standard. For methanol analyses the headspace was not used and the cost of the equipment used was lower. A detailed determination of the esters helped the deeper knowledge of the biodiesel composition. The report of the experiments and conclusions of the research that resulted in the development of alternative methods for quality control of the composition of the biodiesel produced in Brazil, a country with considerable variability of species in agriculture, are the goals of this thesis and are reported in the following pages

Mensuração do ativo imobilizado autárquico: convergência entre o POCAL e as IPSAS

No âmbito da New Public Management, a contabilidade pública, a nível mundial, tem vindo a sofrer diversas reformas. Em Portugal a reforma iniciou-se nos anos 90, atingindo o seu ponto alto com a publicação do POCP em 1997, sendo em 1999 publicado o POCAL com aplicação à Administração Local. Cerca de 17 anos após a sua aprovação verifica-se que o sistema atualmente em vigor não produz informação com a qualidade desejável e adequada às necessidades dos diferentes utilizadores. A crise económico-financeira mundial dos últimos anos – na qual Portugal se encontra envolvido - bem como o ambiente de globalização vêm acentuar a necessidade da qualidade da informação financeira e a necessidade da adoção de princípios e procedimentos semelhantes nas diferentes entidades públicas. A divergência entre os normativos nacionais e internacionais leva a que não haja harmonização contabilística, prejudicando a comparabilidade das demonstrações financeiras entre os países, e também entre as entidades dos diferentes subsetores da Administração Pública. Deste modo, torna-se essencial a harmonização das normas contabilísticas, nomeadamente entre os Estados Membros da UE e, dentro dos próprios países, entre os diversos setores. Em 2012, com a criação de um comité de normalização contabilística público, iniciaram-se os trabalhos técnicos com vista à aprovação de um único Sistema de Normalização Contabilística-Administrações Públicas (SNC-AP) adaptado às normas internacionais de contabilidade específicas para o setor público (IPSAS) e às leis nacionais em que estas matérias são reguladas. Considerando a iminência da adoção das IPSAS em Portugal, neste estudo, procura-se fazer uma análise comparativa entre as normas portuguesas (nomeadamente o POCAL e o CIBE) e as normas internacionais (nomeadamente a IPSAS 16, “Propriedades de Investimento”, a IPSAS 17, “Ativos Fixos Tangíveis” e a IPSAS 31, “Ativos Intangíveis”), de forma a contribuir para o conhecimento sobre as alterações esperadas nos critérios de mensuração dos bens do ativo imobilizado das autarquias locais, identificando as situações omissas e os principais pontos de convergência e de divergência entre os diferentes normativos.
