Desenvolvimento da síntese total do (±)-ácido jasmônico visando aplicação em escala industrial
(Universidade Federal de São Carlos, 2013-05-29) Secatto, Marcelo; Brocksom, Timothy John; https://lattes.cnpq.br/7055452150201902; https://lattes.cnpq.br/6774582267909796
Jasmonic acid is a plant hormone that helps in the partition of nitrogen and acts mainly in defense against pathogens. It was first isolated in 1962 from the essential oil of Jasminum grandiflorum, but we know that it can be found in more than two hundred species of plants, including ferns, mosses and fungi. Jasmonic acid is formed biosynthetically from linolenic acid and is obtained by enzymatic steps including cyclization and reduction. It has a cyclopentanone structure with has two stereogenic centers, that gives four possible stereoisomers in the R or S absolute configuration. Natural ocurring (2R, 3R)-jasmonic acid is shown in the figure below. In the literature there is some racemic and enantioselective synthetic routes to obtain jasmonic acid and its methyl ester, characterized for having different steps, starting from chiral precursors of relevant cost and a wide range of yields. The objective of this work is the exploration of a racemic synthesis route that is summed up in a few steps aiming high yields, envisaging application in industrial scale, that encompass social trends to develop sustainable culture plantations, with reduced use of pesticides.
Terapia ocupacional social: diálogos com a Política Nacional de Assistência Social
(Universidade Federal de São Carlos, 2013-05-29) Vianna, Eduardo Ewerton Sousa; Barros, Denise Dias; https://lattes.cnpq.br/6607056840278610; https://lattes.cnpq.br/7314334659415304
The 1988 Brazilian Constitution introduces social welfare as a social security policy and a citizen s right. This way the promulgation of the Organic Law of Social Welfare in 1993 and the creation of a decentralized public system led to the approval of the Social Welfare National Policy (SWNP), whose management is undertaken by the Unified Social Welfare System (USWS). The National Counsil of Welfare, supported by the Ministry of Social Development and Hunger Alleviation (MSD), proposed the debate process for the definition of Social Welfare workers (DPDSWW) and also to help on the definition of the teams that would become responsible for organizing and providing social assistance services. Occupational therapists and other professional groups were included in this process; in the outcome occupation therapy was ratified as an integral part of the USWS. This study aims to contribute to the debate on occupational therapy in USWS by describing mobilizations and arguments for the recognition of its contribution and importance in this context, during the participation of the professional group in the DPDSWW. This is a study which took form with the data collected in the documentary research on the regulatory frameworks of SWNP and USWS, and also with correspondences taken from the online discussion forum of National Workgroup on Occupational Social Therapy (GNTOSOCIAL, in Portuguese) which is organized and coordinated by the Brazilian Association of Occupational Therapists (ABRATO, in Portuguese). Interviews (with three of the protagonists) and questionnaires (performed with nine occupational therapists from GNTOSOCIAL) complemented this data. We were able to identify which occupational therapists and institutions have participated in DPDSWW and how they have worked. We verified that ABRATO organized associations, the METUIA Project, occupational therapists and teachers around the GNTOSOCIAL discussion forum. A national movement was constructed from this list for the participation of the professional group in DPDSWW. This group faced constraints on being present in all regions and participating in debates, seeking consensus and earning new subscriptions to their cause. GNTOSOCIAL s participation was crucial for the outcome of the DPDSWW, as acting foundations for occupational therapists in social warfare were brought to debate. We found that new challenges are being faced by occupational therapists after DPDSWW. However, the modification of curricular guidelines seems urgent, as it should emphasize subjects regarding social occupational therapy and ensure students gain experience from the social welfare network, with qualified tutors in the social field. Research and postgraduate training are important for social occupational therapy when it comes to individuals skill development, their own knowledge and services, which are offered by several social policies.
Geração de dados espaciais vagos baseada em modelos exatos
(Universidade Federal de São Carlos, 2013-05-29) Proença, Fernando Roberto; Ciferri, Ricardo Rodrigues; https://lattes.cnpq.br/8382221522817502; https://lattes.cnpq.br/6047196867054522
Geographic information systems with the aid of spatial databases store and manage crisp spatial data (or exact spatial data), whose shapes (boundaries) are well defined and have a precise location in space. However, several spatial data do not have precisely known boundaries or have an uncertain location in space, which are called vague spatial data. The boundaries of a given vague spatial data may shrink or extend, therefore, may have a minimum and maximum extension. Clouds of pollution, deforestation, fire outbreaks, route of an airplane, habitats of plants and animals are examples of vague spatial data. In the literature, there are currently vague spatial data models, such as Egg-Yolk, QMM and VASA. However, according to our knowledge, they focus only on the formal aspect of the model definition. Thus, real or synthetic vague spatial data is not available for use. The main objective of this master thesis is the development of algorithms for the generation of synthetic vague spatial data based on the crisp models of spatial data vague Egg-Yolk, QMM and VASA. It was also implemented a tool, called VagueDataGeneration, to assist in the process of generation such data. For both the algorithms and the tool, the user is able to set the properties related to the data type of model, such as size, shape, volume, complexity, location and spatial distribution. By using the proposed algorithms and the VagueDataGeneration tool, researchers can generate large samples of vague spatial data, enabling new research, such as testing indexes for vague spatial data or evaluating query processing over data warehouses that store vague spatial data. The validation of the vague spatial data generation was conducted using a case study with data from vague rural phenomena.
