Full textLa osmosis inversa (OI) es la tecnología de membrana que proporciona el nivel más fino de separación y una de las tecnologías más prometedoras para superar el problema de la escasez mundial de agua limpia. El mercado de membranas de RO está dominado por las membranas de material compuesto de película fina (TFC) de poliamida. Cuando se operan a altas temperaturas (max 45°C) y alta presión (máximo 82 bar), pueden sufrir compactación, lo que resulta en una reducción de la producción de permeado (> 30%), que tiene que ser compensado con un aumento de la presión de alimentación para satisfacer los parámetros de diseño. Esto acaba resultando en un aumento en el coste del agua producida y una reducción sustancial de la vida útil del producto. El objetivo de este estudio fue obtener una comprensión fundamental de los fenómenos de compactación y su implicación en el mecanismo de transporte. Con este fin se llevaron a cabo una serie de análisis, con el objetivo de caracterizar: (1) la modificación de la morfología y el espesor de cada capa en la membrana, a partir de imágenes de sección transversal, como resultado de la alta temperatura y la presión de operación (2) el contenido químico de poliamida después de la operación del proceso (3) la parte de la pérdida de flujo de permeabilidad debido a la compactación de la capa de poliamida y la capa de soporte, por separado, y su contribución a la pérdida total de flujo de membrana mediante la aplicación del modelo de resistencia en serie, y (4) el tamaño de poro (el volumen agujero libre) de la capa de poliamida seca e hidratada. En total, 11 técnicas diferentes se aplicaron en un intento de revelar la información completa. Se identificaron varias observaciones que podrían atribuirse a la pérdida de permeabilidad de la membrana después de la operación. Además, los resultados indican que hay una parte considerable (~50%) de la resistencia extra causante la perdida de flujo que procede de la capa de poliamida, lo que conduce a cambios irreversibles en el rendimiento de la membrana. La causa raíz de estas observaciones podría ser los cambios en la estructura de poliamida, que más probablemente se produce durante la operación en las condiciones combinadas de alta presión y alta temperatura.
Reverse osmosis (RO) is the finest level of membrane-technology available and one of the most promising technologies to overcome the problem of global clean water scarcity. The RO membrane market is dominated by thin-film composite (TFC) polyamide membranes. When operated at high temperature (max 45˚C) and high pressure (max 82 bar) membranes can suffer compaction, which results in reduced permeate production (>30%) so that the feed pressure has to be increased to meet the design parameters. Ultimately these translate into an increase in the cost of the water produced and substantially lower membrane product life-time. The objective of this study was to gain fundamental understanding on the compaction phenomena and its implication to the transport mechanism. With that purpose a series of analyses were conducted with the aim of characterizing: (1) the membrane morphology and thickness of each layer in the membrane from cross sectional images as a result of high temperature and pressure operation (2) the polyamide chemical content after process operation (3) the portions of permeability flow loss due to compaction of the polyamide and support layer, separately, and their contribution to the total membrane flow loss by applying the series resistance model, and (4) the pore size (free-volume hole size) of the polyamide layer in dry and swollen hydrated state. In total 11 different techniques were applied attempting to reveal complete information. Several observations were identified that might be attributed to the permeability loss of the membrane after the operation. Moreover the results indicated that there is a sizable portion (~50%) of added resistance coming from the polyamide layer to the total flow loss of the entire composite membrane, which leads to irreversible changes in the membrane performance. The root cause for these observations might be the changes in the polyamide structure that most probably occurs during the operation at combined conditions of high pressure and high temperature.

Full textThe purpose of this paper is to analyze environmental sustainability reporting with focus lying on climaterelated factors. Three listed companies in Sweden and Germany are reviewed with the help of content analysis of the entities annual and sustainability reports and the specification takes place in a comparison between the environmental reporting of each company. In this essay there has been a usage of both quantitative and qualitative research strategies and takes its premise in an abductive approach. Through content analysis and quantification of qualitative data the empirical base has been collected from companies in the pharmaceutical, business system and electronics industries. By combining three theories, specifically the legitimacy, stakeholder and harmonization theory the possibility of qualitative analysis and well-founded conclusions together with guidelines on further research are made possible. The essay concludes that the German companies are marginally better in terms of sustainability reporting and that industry practice is essential when it comes to accounting for climate- related sustainability factors

Full textWine is known for its favorable biochemical properties such as antioxidant, anticarcinogenic and anti-inflamatory properties. Many of these properties can be assigned to flavonoids and resveratrol. Wine is known to contain high amounts of interferences, such as proteins and lipids complicating analysis of flavonoids and other compounds of interest. Turbulent Flow Chromatography (TFC) on-line coupled to Liquid Chromatography Mass Spectrometry (LC-MS) was used to analyze flavonoids present in different types of wines. The TFC sample pretreatment is based on the fast removal of high molecular weight compounds and the removal of low molecular weight polar interferences. After the sample pretreatment, the TFC column is on-line coupled to LC-MS and a gradient is started to elute the trapped compounds and separate these in the LC-MS. The method proved to be fast, non-laborious, robust and sensitive. The feasibility of the method was tested on several red, white and rosé wines. Interday and intraday precision for all wines and concentrations were calculated to be < 12% and < 18%, respectively. The method proved to be linear for all investigated compounds and matrices in the range of 0.05 to 2 mg L-1 (r2 > 0.99). Moreover resveratrol showed also linearity (r2 > 0.99) in higher range (1 to 50 mg L-1). The LOD for the compounds in red wine ranged from 0.004 to 0.022 mg L-1, in white wine ranged from 0.002 to 0.021 mg L-1 and in rosé wine ranged from 0.003 to 0.034 mg L-1. Quantitation of resveratrol was possible using standard addition procedure, since resveratrol was present in the sample. Red wine showed a higher amount of resveratrol (4 mg L-1), compared to rosé and white wine which was 10-fold lower. Moreover, the different red wines contained also different amounts of resveratrol. The presented method may be an useful tool to study other analytes in difficult matrices, such as compounds of interest in food, drinks and biological samples.
O vinho é conhecido por suas propriedades bioquímicas benéficas como antioxidante, anticarcinogênico e antiinflamatório. Muitas destas propriedades podem ser atribuídas aos flavonóides e ao resveratrol. No vinho encontra-se uma grande quantidade de interferentes, como proteínas e lipídios, que dificultam a análise de flavonóides. Cromatografia de Fluxo Turbulento (TFC, do inglês Turbulent Flow Chromatography) acoplada on-line ao LC-MS foi utilizado para analisar flavonóides e resveratrol presentes em diferentes tipos de vinho. O preparo das amostras é baseado na remoção de compostos com alta massa molar de compostos de baixa massa molar utilizando TFC. Após o preparo das amostras a coluna de TFC é colocada on-line com o LC-MS e um gradiente é iniciado para realizar a eluição dos compostos retidos nos poros da fase estacionária da coluna de TFC e a separação dos mesmos nos sistema LC-MS. O procedimento provou ser rápido, não laborioso, robusto e sensível. A aplicação do método foi realizada com diferentes amostras de vinho tinto, branco e rosé. A precisão interdia e intradia para todos os vinhos e concentrações estudadas foram < 12 % e < 18%, respectivamente. O método provou ser linear para todos os compostos e matrizes estudadas no intervalo de 0,05 a 2 mg L-1 (r2 > 0,99). O resveratrol também mostrou linearidade (r2 > 0,99) quando utilizouse intervalo de concentração maior (1 a 50 mg L-1). O LOD obtido para os compostos em vinho tinto foi de 0,004 a 0,022 mg L-1, em vinho branco de 0,002 a 0,021 mg L-1 e em vinho rosé de 0,003 a 0,034 mg L-1. A quantificação do resveratrol foi possível utilizando-se curva de adição padrão. O vinho tinto apresentou maiores concentrações de resveratrol (4 mg L-1), quando comparado com os vinhos branco e rosé, que foram cerca de 12 vezes menores. Além disso as diferentes amostras de vinho tinto apresentaram diferentes concentrações de resveratrol. O procedimento desenvolvido pode ser uma poderosa ferramenta no estudo de outros analitos em matrizes complexas, como por exemplo compostos de interesse em alimentos, bebidas e amostras biológicas.

The graphic records performed during the design process had major changes in their techniques, instruments and purposes after the appearance of digital tools. Studies on architectural design methodology make clear its complexity as well as the graphical representation mechanisms that assist and record these processes. Computer graphics has not eliminated the instruments and analogue techniques, but added up to them. Today there are a variety of graphical tools to support design process blending analog and digital resources. This diversity is beneficial, but for the efficient exploitation of its potential, requires technical, instrumental and conceptual knowledge that exceed the limits of Geometry, architectural drawing and computer graphics. It is observed in academic circles some deficiencies in the orientation of use of new features in addition to the separation between education / design practice and its relation to the reality of the project. Studies shows the relevance and importance of analog features in the design process as well as defend the coexistence between them and digital resources. The impact of the use of digital instruments simultaneously occurred in professional practice and in architecture schools and, within these, it is observed that the students develop their own procedures to explore this range of options. Aiming to give an overview of these students practice, this dissertation evaluated the analog production, from 2009 to 2014, observed in the discipline Trabalho Final de Graduação (TFG) at the University of Fortaleza in the moments of conceptual design and the presentation of projects. In order to that end, there was a first evaluation of the curricular grade that formed these students and then the drawings produced during professor's orientation and presentations of the TFGs. It was initially made a quantitative survey and a qualitative overview of all work that was deepened through five case studies. The evaluated material shows great attention given to specific drawings during the design process with emphasis on plants and perspectives. The drawings demonstrate technical deficiencies in the graphic execution and little relation to the constructed reality. Digital instruments help the analog designs. The contents of the drawing disciplines do not address this type of hybrid technique. Thus, it is revealed three basic techniques: analog, digital and hybrid. The collected data can help in didactical decisions of design disciplines / drawing, the actual TFG and the interrelation of them. As a result of this study, It is evident that the use of freehand drawing remains relevant in academic circles, but also that it can not be treated in a conservative manner or disconnected from the digital systems way. In addition, it was concluded that we must define and assume, within academic curriculum, a particular drawing for the architect considering all analog and digital technological possibilities
Os registros gráficos executados durante o projeto passaram por grandes mudanças em suas técnicas, instrumentos e finalidades depois do aparecimento dos meios digitais. Os estudos sobre metodologia projetual deixam clara a sua complexidade, assim como a dos mecanismos de representação gráfica, que auxiliam e registram esses processos. A computação gráfica não eliminou os instrumentos nem as técnicas analógicas, mas somou-se a elas. Hoje há considerável variedade de ferramentas gráficas para subsidiar a reflexão e o registro do projeto que misturam recursos analógicos e digitais. Essa diversidade é benéfica, mas, para a exploração eficiente das suas potencialidades, requer conhecimentos técnicos, instrumentais e conceituais que ultrapassam os limites da Geometria, do desenho técnico arquitetônico e da computação gráfica. Observam-se no meio acadêmico algumas deficiências na orientação do uso dos novos recursos, além da separação entre o ensino/prática do desenho e sua relação com a realidade do projeto. Os estudos comprovam a pertinência e importância dos recursos analógicos no projeto, além de defenderem a convivência entre eles e os recursos digitais. A repercussão do emprego dos instrumentos digitais ocorreu simultaneamente na prática profissional e nas escolas de Arquitetura e, dentro destas, observa-se que os discentes desenvolvem procedimentos próprios para explorar essa gama de opções. Com o objetivo de traçar um panorama dessas práticas discentes, esta dissertação avaliou a produção analógica, de 2009 e 2014, observada na disciplina Trabalho Final de Graduação (TFG) da Universidade de Fortaleza nos momentos de concepção e de apresentação dos projetos. Para tanto, primeiramente, foi avaliada a matriz curricular que formou esses alunos e, em seguida o material gráfico produzido nas orientações e apresentações dos TFGs. Para esse último, foram feitos, inicialmente, um levantamento quantitativo e uma análise geral qualitativa de todos os trabalhos, tendo sido esta aprofundada por meio de cinco estudos de caso. O material avaliado revela grande atenção dispensada a desenhos específicos durante o processo projetual, destacando-se as plantas e as perspectivas. Os desenhos demonstram deficiências técnicas na execução gráfica e pouca relação com a realidade construída. Constatam-se instrumentos digitais como auxiliares dos desenhos analógicos, mas também verifica-se que os conteúdos das disciplinas de desenho não tratam desse tipo de técnica híbrida. Dessa forma, revelam-se três tipos básicos de técnicas: analógica, digital e híbrida. Os dados explicitam pontos norteadores de decisões didáticas das disciplinas de projeto, de desenho, do próprio TFG e da inter-relação delas. Como resultado deste estudo, fica evidente que o uso do desenho à mão livre continua pertinente no meio acadêmico, mas também que ele não pode ser tratado de maneira conservadora ou atrelada a processos anteriores ao uso dos sistemas digitais. Além disso, conclui-se ser preciso definir e assumir, dentro dos currículos acadêmicos, um desenho específico para o arquiteto, levando em consideração todas as possibilidades tecnológicas, analógicas e digitais.

Full textExperience has shown that, steel or reinforced concrete shells structures, exposed to severe environmental attacks such as corrosion, or to cyclic load-induced stresses greater than design stresses, or to accidental overloads, are hence subject to damage. The serious deterioration of materials, coupled to design errors or/and to accidental overload can lead to catastrophic failures; or at least, because of the propagation of the damage, to diminution of the structure’s lifetime. It is now of a fairly common practice to repair structures as it is non- expensive and non obstructive upgrading procedure. One of the common techniques for repairing and strengthening steel shells is to weld rings, stringers or local steel reinforcement. Carbon fiber reinforced polymer (CFRP) has established a strong position as an effective mean for the repair and rehabilitation of infrastructures. Composite materials, thanks to their high strength, high stiffness, resistance to corrosion and low weight, can be of great interest in civil engineering structures (generally concrete beams). Their use is particularly interesting, especially in order to increase the structural performance, but also because of the ease to forming, the speed of installation, the optimization possibility (direction’s reinforcement choice) and the multifunctional (strength, anti-corrosion, tightness). However, the use of CFRP in the repair and reinforcement of steel or concrete shells is a new concept that has the potential to improve the way we repair shells. In our studies we show the benefits of using CFRP for the reinforcement of shells submitted to axial compression or combined loads like internal pressure, axial compression and bending. A large experimental and numerical study is carried out on steel cylindrical shells reinforced with the CFRP at different radius to thickness ratio. We show that the load capacity can be enhanced more than 50%. Numerical simulations are also conducted using finite element approach

Full textSquamous cell carcinoma raises a great interest regarding carcinogenesis and its proliferative pathways, due to the high incidence and poor prognosis. The broad genetic and proteic profiles contribute to this poor prognosis. The present study aims to better comprehend the role played by pAkt, key protein for the development of many neoplasms. Cell lines derived from oral squamous cell carcinoma (HaCat, HN6, HN19, HN30 and HN31) were induced with 10ng/ml EGF and 5ng/ml TGF β . The expressions of pAkt, cyclin D1, Bad, caspase-3 and PTEN were analyzed through immunofluorescence, western-blot and immunoprecipitation. Results showed higher pAkt and cyclin D1 expression after EGF treatment, as well as a decrease in Bad and PTEN levels, except for HN31. Immunoprecipitation revealed that pAkt prevents apoptosis through Bad direct inactivation. However, TGF β treatment revealed different results, from what expected for this tumor supressor. pAkt expression revealed to be increased in all cells lines, but stable for HN19 and HN31. HaCat exhibited decreased levels of caspase-3 and Bad, which were unaltered in HN6, augmented in HN30. HN31 revealed only Bad increased levels, and no alterations in HN19. These findings suggest the crucial role played by EGF stimulation in the studied cell lines, and a good candidate to be targeted by chemotherapeutical approaches. TGF β treatment showed discrepancies, revealing diverse behaviors in the different cell lines. An exhisting relation between TGF β receptors and pAkt pathway may not be discharged, requiring further studies. The low occurrence of apoptosis reinforces this possibility, showing how important is Akt and related pathways for neoplastic progression, and its possible relation to cellular events not described to date.

Full textThis research analyses the production of the conservation territory under influences of various actors located at different scales of power and management. From the approaches Territorialization – Desterritorialization – Reterritorialization, we analyze the transition of Chimanimani as a community area, formed by several communities, whose identity is enshrined in the various sacred sites of area, to a conservation area, which resulted in (re)structuring space to answer conservation and ecotourism. Transformations that occurred and are occurring in Chimanimani are part of an overall process, begun in the late 80’s with the introduction o Economic Rehabilitation Programs. These changes submitted the place to the global and moved the command of the area for other scales of power and management. These transformations which Chimanimani are involved implicated a transition of the agriculture as the survival base for the ecotourism. The dependence on ecotourism as the activity that better reconcile the exploration of natural resources in an area of conservation does not seem to find a framework in the dynamics of tourism in Mozambique, which is preferably tourism “Sun and sand”. How to boost tourism in conservation areas is a challenge for the Mozambican reality, whose conditions make it difficult to ecotourism development in remote areas far from the coastal region. In this dilemma, it is proposed Social Tourism as a possibility for the development of tourism in conservation areas.

Full textThis study aims to investigate the knowledge mobilized by students who have already studied the Fundamental Theorem of Calculus (FTC) regarding the concepts of differentiation and integration and its relationship. The FTC is one of the most important topic in any Calculus course according to Segadas (1998). The intention of the study is to evaluate if the mobilization of these concepts occurred in the proper manner for specific questions resolution where necessarily they have to be applied. The research was based on Douady s (1987) theoretical beliefs of the tool-object dialectic and change of frameworks. As support the study was carried through Segadas (1998) research on the understanding of the FTC by students at the end of the course of Calculus. A pilot-questionnaire was applied to students of a Computer Science course in a private University of São Paulo city. In this first inquiry we perceive the participant students had not received the FTC related content in the deep required for our research in this course. Thus we have decide restructure the questionnaire and apply it to a different group of students in the Mathematics Bachelors course where the FTC content was teach deeper due to greater teaching load in the same university. The research found the majority of the students have found difficulties to solve problems where the simple visualization of graphs would solve it without developing extensive algorithms. This findings shows the students obstacles to understand the FTC are related to an incomplete mobilization of differentiation, integration and continuity concepts since to solve the given questions they have only partially used these knowledge. Such fact is probably associated the students habits who do not tend to focus their attention to the conceptual aspects of the theorem but only memorizing the procedures algorithm without reflecting on its applicability. The theoretical fundamentals used revealed an efficient tool in the analysis of the protocols who led us to these conclusions
Este estudo teve por objetivo investigar os conhecimentos mobilizados por alunos que já haviam estudado o Teorema Fundamental do Cálculo (TFC) relativamente aos conceitos de derivada e integral e sua interelação. O TFC, segundo Segadas (1998), é um dos tópicos mais importantes em qualquer curso de Cálculo. Pretendemos com o trabalho avaliar se a mobilização desses conceitos se deu de forma adequada na resolução de questões específicas em que a aplicação desses conceitos era necessária. A pesquisa fundamentou-se nos pressupostos teóricos da dialética ferramenta-objeto e jogos de quadros de Douady (1987). Teve como base a pesquisa realizada por Segadas (1998) sobre a compreensão do TFC pelos alunos ao final do curso de Cálculo. Foi aplicado um questionáriopiloto a alunos do curso da Ciência da Computação de uma universidade particular da cidade de São Paulo. Percebemos nessa primeira investigação que alunos que participaram do estudo piloto não haviam recebido o conteúdo relativo ao TFC com a profundidade requerida pela nossa pesquisa. Reestruturamos o questionário e reaplicamos a um grupo alunos do curso de Licenciatura em Matemática desta mesma universidade, onde esta disciplina é ministrada com maior carga horária. Verificamos que a maioria dos alunos encontrou dificuldades para solucionar problemas em que a simples visualização de gráficos faria com que não necessitassem desenvolver longos algoritmos. Este resultado demonstra que os obstáculos dos estudantes para compreender o TFC estão relacionados com uma incompleta mobilização das noções de derivada, integral e continuidade, uma vez que utilizaram apenas parcialmente esses conhecimentos para a solução das questões apresentadas. Tal fato está provavelmente associado aos hábitos dos estudantes, que tendem a não focar atenção aos aspectos conceituais do teorema, apenas memorizando o algoritmo dos procedimentos sem refletir sobre a sua aplicabilidade. A fundamentação teórica mostrou-se uma ferramenta eficaz na análise dos protocolos que nos conduziram a essas conclusões

Full textThis work shows and discusses didactic and pedagogical dimensions of the Undergraduate Final Work (TFG) of some Brazilian courses in architecture and urbanism, especially studying the process of design. Products and processes of TFG are taken as an object of study, in order to discuss principles and values of the architectural and educational field which, linked to qualification criteria of excellence considered, are present on the TFG and, broadly, in the formation of the architect and the urban planner. Also, this work aims to discuss the frameworks from which students make their decisions, showing important guidelines for teaching and learning of architecture and urbanism in the contemporary context. This is a qualitative research, with former students and teachers in six courses in architecture and urbanism of the cities of São Paulo and Belo Horizonte. The object of study is here approached from the theoretical fields of education, architecture and urbanism, under the perspective of the sociology of culture and the sociology of education. Research indicates that the TFG is one of the most intense moments of learning in courses. This is due to its potential for disciplinary integration and to the greater autonomy given to the student who is, in fact, the protagonist of the processes. This is also due to the teacher-student relationship established from this autonomy and to the methodologies underlying the continuous questioning of the processes, both didactic and pedagogical as project methodologies. However, despite the critical and reflective view of these methodologies, principles and values that circulate through the processes remain connected to the practices and thoughts associated with Modern architecture, particularly the ideals of rationality, functionality and architecture\'s artistry and the notion of the architect creator, with universal and deterministic views. Also, the TFG shows the teaching and learning in architecture and urbanism, especially in the project area, as a place of production and reproduction of thoughts and modes of operation that have long marked the profession in the social imaginary. Such thoughts and modes of operation do not consider the diversity and heterogeneity and, indeed, they give the architect and urbanist limited scope for professional action, especially in the face of demands and constraints of contemporary Brazilian context.

Full textTulbaghia violacea Harv. (wild garlic) has been used in traditional medicine in Southern Africa for the treatment of various ailments. Despite the widespread use and popularity of this medicinal plant as a herbal medicine, there is contradictory evidence regarding the safety and toxicity of the plant. The phytochemical profiling of the plant has also been neglected in research. The determination of chemical constituents present in plant material as well as the potential toxicity found in plants are preliminary steps necessary for the discovery and development of novel therapeutic agents with improved efficacy. The aim of this study was to evaluate the cytotoxic and genotoxic potential of crude extracts from the leaves, stems and roots of T. violacea. This was performed in vitro using aqueous and ethanol extracts of the leaves, stems and roots. The aim of the study was achieved by three major objectives; (1) to identify the active phytocompounds present in the leaves, stems and roots, (2) to assess the cytotoxicity using the MTT (3-(4, 5-dimethylthiazolyl-2)-2, 5-diphenyltetrazolium bromide) cell proliferation assay, and (3) to evaluate the genotoxic potential of the leaf, stem and root water extracts using the Allium cepa assay. A total of 14 phytochemicals were each extracted separately with distilled water and 70% ethanol by maceration from the leaves, stem and roots of T. violacea. The results of the qualitative phytochemical analysis showed that pharmacologically active compounds such as tannins, terpenoids, flavonoids, saponins, proteins, steroids, cardiac glycosides, phenols and coumarins were present in some organs of T. violacea. However, phlobatannins, leucoanthocyanins, alkaloids, carbohydrates and anthocyanins were absent in all plant parts. Overall, the leaves of the plant contained more active compounds than those present in the stems and roots when both water and 70% ethanol were used as the extractants. The quantitative phytochemical analysis for the Total Flavonoids Content (TFC) and Total Phenolic Contents (TPC) was also assessed. The water (0.027 mg/g) and 70% ethanol (0.053 mg/g) were most effective in extracting flavonoids from the leaves while the least amounts were obtained from the stems and roots. This observation was similar to the TFC were the water extracts of the leaves were the most effective in extracting phenols followed by the stems and roots. The MTT assay was conducted using two cell lines RAW 264.7 and C2C12. The experiment was conducted in triplicates for the leaf, stem and root extracts (water and ethanol) of T. violacea. The experimental design employed a 23 factorial design where three independent variables (concentration, incubation time and type of extracts) were selected using two levels for each variable (high (+) and low (-)). The results illustrated that both the water and ethanol vi extracts only showed a significant reduction in the number of viable cells at the concentration higher than 250 μg/ml treatment for both RAW 264.7 and C2C12 cells. The ethanol extracts from the leaves, stems and roots were found to be toxic towards the RAW 264.7 cells even at lower concentrations at both 24 and 48 h incubation periods (% cell viability < 50%). The water extracts were non-toxic to RAW 264.7 cells except for the water stem extract which showed toxicity after 48 h incubation (IC50 = 9.475 (4.061 to 23.39)). For the C2C12 cells, the lowest potent toxic concentration was 250 μg/ml for the ethanol extract of the stem after 48 h incubation. Overall, the T. violacea plant extracts were non-toxic as percentage cell viability greater than 50% was noted for both extraction solvents in all the plant parts of T. violacea. No cytotoxic activity was observed in all T. violacea plant parts with the C2C12 cell line (IC50 > 30 μg/ml). For the Allium cepa assay, only the water crude extracts of the leaves, stems and roots of T. violacea were used. A similar trend of potent genotoxic activity in the water stem extracts compared to the leaf and root extracts at the concentration ranges studied. Similar to the MTT assay, it is clear from the study that at higher concentrations, the water crude extracts from the leaves, stems and roots of T. violacea is toxic. From this study, it can be concluded that the extraction of compounds using water is more efficient than using ethanol. Overall, the T. violacea leaf extracts extracted the most phytocompounds and showed the highest percentage of viable cells as well as desirable IC50 values. However, preparation of herbal remedies using T. violacea plant extracts should be done with caution due to their possible genotoxic and cytotoxic potential at higher concentrations. This study raises a need to further conduct in vivo cytogenetic studies to ascertain the possible toxic effects of T. violacea crude extracts.

As the evolution of the end users' needs toward multimedia applications, an important feature of the third generation mobile networks like UMTS attempts to support efficiently multiple applications of different qualities of service. In the Radio Access Network, the RLC/MAC layer has also been designed to accommodate simultaneously mixed services through establishing multiple bearers. Thus, a major issue is the rate adaptation of these bearers. Moreover, third generation radio interface provides procedures to the rate adaptation in the lower layers such as PHY, MAC or RLC layer. In the paper, we focus on MAC layer and propose five scheduling methods in terms of different considerations. The five methods are strict priority method, partially dynamic priority method, dynamic priority method, probability priority method and load measurement based priority method. Our simulations show that load measurement based priority method can maintain better fairness and achieve better performance than the other four methods. Furthermore, the computation time of the load measurement based priority method is one of the smallest of the five methods.

Abstract The existences of the non-profit organizations (NPOs) are getting more and more important. However, the malpractices of NPOs, such as the illegally great wealth transfer, misuse of donations and improper political activities, have gradually emerged. In order to ensure the donations used properly and establish the better goverance mechanisms, an evaluation of nonprofit governance is needed to solve the problems. Based on the governance, the purpose of this study was to evaluate if Taiwan Fund for Children and Families (TFCF) had met its mission and goal on the expense of the child welfare. It could be divided into self-discipline (internal corporate governance) and other-discipline (external corporate governance). The internal corporate governance means the controlling mechanisms regulated by the organization. The external corporate governance means the controlling mechanisms commanded by the government or other legislations. The results of this study were as follows: 1. From the internal governance assessment, TFCF was honored by the Ministry of the Interior for Excellence in the integration of the administration, business and financial activities. As for the accountability of the finance, it was noted that TFCF was rated 100 points in 2011 from the assessment made by the Ministry of Interior. It had motivated TFCF to promote welfare services for more needed children. 2. From the external governance assessment, TFCF’s achievement rate of tax-exempt nonprofit had reached a high record year by year. And the children and youth services also had been well supported by the government. In addition, the Ministry of the Interior would entrust the professional accountants in the middle of every year for the audit of fundraising programs implemented in the previous year to check if they were implemented according to the Charity Donations Act. They always turned to good results. Keyword:governance mechanisms, nonprofit organizations, sustainable development

Abstract N-acylamino acid racemase (NAAAR) catalyzes the racemization of optically pure D-Nα-acylamino acids and L-Nα-acylamino acids. In this study, an NAAAR assay system has been developed in which the N-acetyl-D-methionine was used as substrate. Coupled with the catalytic reactions of L-aminoacylase, L-amino acid oxidase, and peroxidase, the color development at 520 nm was detected to determine the enzyme activity. Besides, Chiral HPLC can also detect the product of the NAAAR catalytic reaction directly. Thermoactinomyces sp. TFC-333 is a wild-type strain, which may produce NAAAR. In order to get sufficient cells for NAAAR purification efficiently, the growth condition of the bacteria should be revealed and applied for large-scale fermentation. TSB medium containing 1 % glucose can be a suitable medium for cell growth and NAAAR production. The wet weight of cells harvested from 60 l of production medium by continuous centrifugation was about 550 g. The cells were suspended and disintegrated in Tris buffer to get lysate. After heat treatment, the nucleic acid in the lysate was precipitated by protamine sulfate, and some protein was precipitated and removed by ammonium sulfate fractionation at 40 % saturation. The supernatant obtained after centrifugation was loaded on a hydrophobic interaction column, the active fractions were collected and dialyzed against Tris buffer. The dialyzed fraction was applied on an ion-exchange column for further purification. The acive fractions were assayed by Chiral HPLC to comfirm that it did contain NAAAR activity. After the ion-exchange chromatography, the purification fold of NAAAR was 3.24, the recovery rate was about 0.02 %, and the specific activity was 11.6234 mU/mg.

In this research, polyamide thin-film composite (TFC) membranes were fabricated by interfacial polymerization, and applied to pervaporative dehydration. To explore the relationship between the pervaporation performance and the properties of polyamide TFC membranes, such as morphology, chemical properties, hydrophilicity, surface roughness, and free volume properties, the membranes were characterized by SEM, XPS, ATR-FTIR, WCA, AFM, and VMSPB. Properties of various modified polyacrylonitrile (mPAN) membrane supports were measured; these supports were obtained by hydrolyzing asymmetric PAN membranes, as a result of immersing them in NaOH solution at different lengths of time. Results showed that the size and amount of pores on the mPAN membrane surface were decreased with the hydrolysis time, but there was practically no change in the macrovoids structure. From VMSPB results, S and R parameters and o-Ps annihilation lifetime (τ3) and intensity (I3) of mPAN membranes were reduced with the hydrolysis time, especially the R parameter and I3. Quenching and inhibition effects on formation and annihilation of positronium occurred in the mPAN membranes with longer hydrolysis time, due to their higher oxygen atomic concentration, which was associated with higher electron affinity, resulting in the decrease in R parameter and I3. Results demonstrated the effect of specific chemical environments on the free volume properties, and illustrated the relationship between chemical structure and positron data for the mPAN membranes. For the pervaporation performance in separating 90 wt% aqueous ethanol solution at 25oC, the permeation flux was reduced and the concentration of water in permeate improved with the hydrolysis time. To improve the pervaporation performance, novel TFC membranes were prepared by interfacial polymerization using new acyl chloride monomers, NTAC and TBAC, with the use of an mPAN membrane support at an optimal hydrolysis time. The effect of the monomer structure on chemical properties, microstructure, and pervaporation performance was investigated. Experimental data indicated that compared with the TETA-NTAC/mPAN membrane, the TETA-TBAC/mPAN membrane had a thinner polyamide layer with a denser structure, a rougher and lower degree of cross-linking surface. A possible reason was that the denser polyamide film formed on the mPAN membrane support, as a result of the TETA monomer reaction with the TBAC monomer, which had a higher reactivity with TETA due to the higher affinity between TETA and TBAC monomers, compared with NTAC, restricted the diffusion of the TETA monomer into the organic phase solution, resulting in a smaller thickness of the polyamide layer. The thicker and higher cross-linking polyamide layer of TETA-NTAC/mPAN membrane was the dominating factor affecting the membrane resistance during pervaporation, and caused a higher permeation flux (537 g/m2-h) and a higher concentration of water in permeate (98.2 wt%), despite its larger free volume size and higher free volume concentration. The mechanism of polyamide formation during interfacial polymerization is an important fundamental knowledge for understanding the properties of the polyamide layer of TFC membranes. Polyamide/PTFE TFC membranes were fabricated by interfacial polymerization using a porous PTFE membrane support with a hydrophilic or a hydrophobic surface. The polyamide layer surface at initial or final stages of interfacial polymerization could be controlled by the procedures of interfacial polymerization during the preparation of polyamide/PTFE TFC membranes. We found that growth of the polyamide film was affected by the surface property of the PTFE support. In the case of a hydrophobic PTFE membrane support, the growth direction of the polyamide film was inward, resulting in a thinner polyamide layer with a smoother surface, a higher cross-linking degree, and a less hydrophilic surface, which was formed at the initial stage of interfacial polymerization. On the other hand, the growth direction of the polyamide film on a hydrophilic PTFE membrane support was outward, leading to a thicker polyamide layer with a rougher surface, a lower cross-linking degree, and a more hydrophilic surface, which was formed at the final stage of interfacial polymerization. The differences in free volume properties of the polyamide formed at initial and final stages of interfacial polymerization were shown by means of VMSPB; results showed that the free volume size of the polyamide formed at the initial stage was larger than that at the final stage of interfacial polymerization. For the pervaporation in separating a 70 wt% aqueous IPA solution at 25oC, the polyamide/hydrophilic PTFE TFC membrane exhibited a higher performance than the TFC polyamide/hydrophobic PTFE membrane. Incorporating a novel inorganic layered material, graphene oxide (GO), into the polyamide layer of TFC membranes could increase the tortuosity and permeation routes of permeants, resulting in improving the pervaporation performance in dehydrating aqueous alcohol solutions. Results indicated that the GO with an exfoliated structure was dispersed in the polyamide layer, and the hydrogen bonding interaction between GO and polyamide inhibited the motion of the polyamide chain, resulting in decreasing the free volume of polyamide. For dehydrating a 70 wt% aqueous isopropanol solution at 70oC, permeation flux, concentration of water in permeate, and PSI of the resulting membrane with an optimal GO content in the polyamide layer were determined as 10396 g/m2-h, 99.0 wt%, and 2.40 ×106, respectively. The superior pervaporation performance showed potential for commercialization purposes. This research correlated the relationships between membrane characteristics and performance by means of analyzing the fundamental properties of the multilayered structure of TFC membranes, which were prepared by interfacial polymerization. Results showed excellent performance during the pervaporative dehydration. Understanding the relationships would then furnish significant information about the areas of membrane structure design and membrane performance prediction.

Mechanical manufacturing of the machine tool industry starts with the complicated professional arrangement of machinery planning, controller, motor selection, diverse metal plate and fitting process, PLC (Programmable Logic Controller), and human machine interface developing based on the need of machining parts. It produces the machining equipment with uniqueness and peculiarity to present sophisticated machining technique. There are two main parts in manufacture of the machine tool, machinery and electrical control. Machinery designers with excellent drawing skills and machinery analysis capability manage to draw down 2D and 3D by computer assist in machinery part. On the other hand, Electrical control engineers with professional programming and circuit planning abilities take charge to execute circuit diagram by computer-aided program. The computer software contrives designs and diagrams from the two parts. It can store up related data to develop much more multivariable and sophisticated machine tool design case. Nonetheless, mechanical material list, metal plate diagrams,3D composite diagrams related to the machinery part, electrical control material list, circuit diagram, PLC program, and other related information. Those machinery file gradually increases after more designed and produced machine tools by years.Those archives are all intangible assets in most companies and must to be systematically integrated. The new developed machine tools or coincidental orders can be used by the reference in the future. Therefore, they need to be managed variously by a safe platform with systematization and science. This dissertation will conduct the information security in original Total File Guard(TFG) in consequence and adapt Product Data Management(PDM) system for processing the function of archives control. The researcher hope the management of machine tool manufacturing could be more efficient and popularize the resource application and sharing.

Antiscalant has been developed to reducing the fouling layer of water treatment processes for many years, major solving the fouling problem of membrane and extending the membrane life time. The purpose of this study is to synthesize new antiscalants for the purification of steel industrial wastewater and to explore the antifouling efficiency of antiscalant in the RO TFC process. Based on the phosphonate (PBTC), incorporate the inorganic, chelating agents, surfactants and polymers were testes by using the cross flow RO unit. The performance of antiscalants were evaluated by permeation flux, membrane contact angle and functional group of scaling layer on membranes. The results showed that at PBTC 2mg/L, feeding the ferric chloride, aluminum chloride, zinc chloride and sodium silicate to the steelmaking wastewater, forming precipitant which to alter the surface roughness of membrane due to the change of water alkalinity. The fatty amine surfactant produced organic fouling on membrane due to adsorption on the membrane surface. PEG 400 with PBTC reacted with the soluble protein produce precipitant which to alter the surface roughness of membrane and permeation flux. Polyethyleneimine has strong cationic charge, can with dissolved organic matter to form smaller floc and less deposition was observed on surface of membrane. Antiscalant F7 contained phosphonate and polyoxyethylene nonionic surfactant to form Ca-phosphonate complexes, it can provide a strong hydrogen bonding with organic material and effective decreased the accumulation of biomass on the surface of membrane. It was found that the permeation flux of the antiscalant F7 is higher than commercial antiscalant ( G company supplied) over 2% .

To improve the pervaporation performance of polyamide thin-film composite (TFC) membranes prepared by interfacial polymerization between 1,2-bis(2-aminoethoxy)ethane (BAE) monomer and 1,3,5-benzenetricarbonyl trichloride (TMC) monomer, graphene oxide (GO) were added into the BAE monomer solution to prepare polyamide-GO/mPAN composite membranes. The synthesized GO was characterized by FT-IR, XRD, AFM and XPS, and the results showed that GO was single layer sheet with hydrophilic functional group such as –COOH groups. Surface and cross-section morphologies of TFC membranes were observed by SEM. In order to further realize the effect of GO content on polyamide layer structure, the positron annihilation spectroscopy (PAS) coupled with a variable monoenergy slow positron beam (VMSPB) is utilized to detect the depth profile of multilayer structure through the polyamide-GO/mPAN composite membrane to correlate with pervaporation performance. It was found that GO content altered pervaporation mechanism of polyamide-GO/mPAN TFC membranes, so that the separation performance improved. On the other hand, the thickness of polyamide layer decreased with increasing GO content. In addition, GO were distributed in the polyamide layer by the interfacial polymerization process from the results of doppler-broadened energy spectrum (DBES) results. The effect of GO concentration on the pervaporation mechanism through polyamide-GO/mPAN composite membrane were diffusion control. The effects of operating condition of pervaporation process, such as the operating temperature, feed concentration, permeate pressure, and feed component, were also investigated. From the results of the pervaporation separation experiments, the polyamide-150ppmGO/mPAN had excellent performance of 90wt% aqueous ethanol solution, which is a permeation flux of 545 g/m2 h and a water concentration in permeate of 97.1 wt%.

Human beings are one of paratenic hosts of Toxocara canis. When people accidentally got infection by T. canis embryonated eggs, T. canis larvae may migrate in the body thus leading to visceral larva migrans. Some studies have indicated that enhanced expression of transforming growth factor-β1(TGF-β1) were found during larval invasion of small intestine, liver, muscle, and brain of T. canis-infected mice. Substantial studies have indicated that TGF-β1 play an important role in kidney injury and fibrosis. Since TGF-β1 is supposed a deleterious cytokine in toxocariasis, we hypothesize that inhibition of TGF-β1 expression will benefit to reduce the severity of the kidney injury. Present study intends to explore the role of TGF-β1 in damage of T. canis-infected mice kidney. Kidney damage associated biomarkers (KDAB) including TGF-β1, proliferating cell nuclear antigen (PCNA), connective tissue growth factor (CTGF), endothelin-1 (ET-1), and alpha smooth muscle actin (α-SMA) in the kidney were assessed by inhibition of TGF-β1 expression using peptide inhibitor (LSKL) via peritoneal injection twice (2.5μg/g-weight) per day. The techniques of immunohistochemistry and western blotting were utilized to insight into the molecular pathogenesis of TGF-β1 involved in regulation of those KDAB involved in kidney damage in toxocariasis. Results indicated that when TGF-β1 expression was reduced, the kidney injury was lessened in LSKL-treated mice as supposedly due to reduced PCNA, CTGF, α-SMA and ET-1 expressions as compared to those in SLLK-treated or infection mice.
