Monitoramento por dgps e análise dos processos erosivos da linha de costa na praia de Pirangi do Norte - Parnamirim / RN

Through out the course of a steady increase in search and recovery of space in the coastal zone, there is also an expanding concern about the erosion processes of this area. The main problem in coastal areas is that urbanization occurs in a disorderly fashion and unsustainable, further aggravating the problems of coastal dynamics. The study area of this work is located on the southern coast of Pirangi do Norte beach to about 20km south of Natal, capital of Rio Grande do Norte in the Parnamirim City. This area has the length of approximately 1km, divided into three sections (Western, Central and Eastern) with a morphology consisting of a tableland at the top, sea cliffs in the West and Central parts and sand dunes in the Eastern section, both vegetated, and a coastal plain on the inferior part associated with the presence of beach rocks. This study aimed to analyze the erosion processes operating in the excerpt of Pirangi do Norte beach and assess the feasibility of their monitoring making use of DGPS (Global Positioning System Differential mode). During the work it was carried out a physical description of the area through photo-interpretation and site survey after measurement of the shoreline in the period between November 2004 and November 2009 and beach profiles between August 2005 and July 2006. The analysis of the results of the annual surveys showed the occurrence of variations of the shoreline along the stretch traveled. Sites are identified in advancement coast from the sea and it was verified in loco the presence of erosion with deposition of materials on the lower part of the coastal bluff, the former position of the shoreline, showing a false notion of advancing it. This leads to the conclusion that the data collected in a survey of the shoreline should always be accompanied by photographic records of the local area and with the highest rate of erosion, thus avoiding the mistake of treating the deposit materials as evidence of progress coast. At the end of the study, after a review of various works to mitigate the erosion in the coastal zone, it is recommended to the area of study the adoption of an artificial feeding of the beach, aiming the minimization of the erosive effects of the tides. Moreover, it is suggested that even the continuity of monitoring, maintenance of existing vegetation and control of the occupation on the edge of sea cliffs

A doença como ponto de mutação :os processos de significação em mulheres portadores de lúpus eritematoso sistêmico

Systemic lupus erythematous (SLE) is a chronic and auto-immune disease that can affect several systems of one´s body, including the nervous system, causing several clinical evidences, which can put in risk the person´s life. Although the illness could manifest itself at any age or sex, studies indicate higher incidence among women. Its etiology points to the combination of genetic, hormonal and environmental factors. Due to the disease´s complexity, it is evident that it affects all the person´s life as a whole and not only its organic dimension. It is believed that the signification attributed to all the process of sickening influences its treatment, as well as the person´s capacity to cope with the difficulties and implicit profits involved in the process.In this study, eight women who were affected by SLE were interviewed, with the aim of examining carefully the processes of signification as well as the generation of meanings which permeate these women´s sickening processes. The analysis of their speeches evidences distinct forms of giving meaning to the process, regardless of the time of the diagnosis. The fact that the disease is incurable was shocking to all the participants, and it demanded changes in their lives, in order to detain a relative control of their condition. The majority of the participants were able to deal with these modifications, since strategies have been created to face the difficulties and thus to preserve their social life, without damaging their health. However, some of the participants did not obtain strenght to cope with the disease, eventually developing a depressive state. It is observed that not only SLE has innumerable ways of manifestation, but the experience of the illness is very subjective and dynamic. There are also several ways of expressing this experience, according to the implications in the social, cultural and economic context where the participants are inserted. This ratifies the necessity of a interdisciplinary approach to embrace SLE complexity. (310 words, 1.610 characters)

O desempenho terminológico dos descritores em Ciência da Informação do Vocabulário Controlado do SIBi/USP nos processos de indexação manual, automática e semi-automática

The terminological performance of the descriptors representing the Information Science domain in the SIBI/USP Controlled Vocabulary was evaluated in manual, automatic and semi-automatic indexing processes. It can be concluded that, in order to have a better performance (i.e., to adequately represent the content of the corpus), current Information Science descriptors of the SIBi/USP Controlled Vocabulary must be extended and put into context by means of terminological definitions so that information needs of users are fulfilled.

Geração de processos WS-BPEL com base em um algoritmo de reescrita de regras

Web services are computational solutions designed according to the principles of Service Oriented Computing. Web services can be built upon pre-existing services available on the Internet by using composition languages. We propose a method to generate WS-BPEL processes from abstract specifications provided with high-level control-flow information. The proposed method allows the composition designer to concentrate on high-level specifi- cations, in order to increase productivity and generate specifications that are independent of specific web services. We consider service orchestrations, that is compositions where a central process coordinates all the operations of the application. The process of generating compositions is based on a rule rewriting algorithm, which has been extended to support basic control-flow information.We created a prototype of the extended refinement method and performed experiments over simple case studies

Metodologia integrada para mapeamento de falhas: uma proposta de utilização conjunta do mapeamento de processos com as técnicas FTA, FMEA e a análise crítica de especialistas

As falhas representam não conformidades nas atividades produtivas, de tal modo que pesquisas para seu controle e prevenção são, no mínimo, desejáveis. Na literatura sobre o assunto, observa-se uma gama variada de técnicas, porém, quase sempre, usadas isoladamente e, em poucos casos, no setor de serviços. Observando essa lacuna, propõe-se uma metodologia de Mapeamento de Falhas que integra diferentes abordagens que se complementam, aproveitando-se o potencial e o benefício de cada técnica para análise e controle de falhas. Para a consecução dessa proposta, efetuou-se uma pesquisa bibliográfica para conceituação e entendimento das técnicas utilizadas, um estudo e análise de integração dessas técnicas e, por fim, um exemplo real de aplicação em processo notarial de serviço, tema este ainda não explorado na literatura pertinente e, portanto, bastante auspicioso. Como resultado, observa-se uma ferramenta que permite uma visualização completa e objetiva das atividades desencadeadas pelos processos, seus pontos críticos e suas potenciais falhas, podendo ser aplicada com propriedade em empresas de prestação de serviços.

Floculação de leveduras por Lactobacillus fermentum em processos industriais de fermentação alcoólica avaliada por técnica fotométrica

Na produção de álcool por fermentação com leveduras, a floculação manifesta-se como um mecanismo natural de agregação de células. Essa condição pode ser induzida por vários fatores, entre eles, a interação entre bactérias floculentas como Lactobacillus fermentum e as leveduras. Esse fato torna-se prejudicial para o processo, pois tanto nas unidades que se utilizam do sistema de recuperação de células por centrifugação, como nas que não o utilizam, ocorrem perdas excessivas de fermento, em conseqüência dos problemas operacionais decorrentes da floculação, comprometendo seriamente o desempenho industrial. No presente trabalho, avaliou-se a floculação em vinho proveniente de fermentação experimental, sob duas condições de pH de fermento tratado utilizadas como inóculo e temperaturas de fermentação, não se observando diferenças significativas entre elas. Com este estudo, pôde-se ainda avaliar a capacidade de dispersão dos flocos em três condições de pH no tratamento do fermento em fase industrial, mostrando diferenças altamente significativas entre elas. A maior capacidade de dispersão no tratamento do fermento é desejável para o controle da floculação industrial, permitindo a sua centrifugação, com conseqüente separação das bactérias contaminantes do fermento. Essas constatações tornaram-se possíveis pelo emprego da técnica usual de determinação da floculação por espectrofotometria, modificada pela desfloculação prévia das amostras de vinho e fermento, o que conferiu maior estabilidade nas leituras.

Análise geoambiental da região de marília, SP: Suscetibilidade a processos erosivos frente ao histórico de ocupação da área

The study area comprises the western portion of the Marília Plateau, State of São Paulo, southeastern Brazil. The geological substrate encompasses Cretaceous sedimentary rocks of the Bauru Group and local Neocenozoic units like colluvium aprons, fluvial terrace deposits, in situ regoliths, and modern alluvial deposits. In a geomorphologic sense, the study area might be characterized as showing two main pediplanes, viz. P1 Surface (upper) and P2 Surface (lower), both surfaces are presently under dissecation processes. After the 1920's the expansion of the railroad system fostered the removal of the natural vegetation, which in turn was followed by the introduction of coffee, peanut, corn and cotton crops. This intense exploitation was conducted without respect to the soil carrying capacity and its natural susceptibility to erosional processes, including an aggressive form known as voçoroca. As a result, the study shows that the most susceptible material includes colluvium aprons, in situ regoliths, and colluvium-alluvium or alluvium deposits. The most critical situation is in the P2 Surface context, near the bottom of the Marília Plateau scarpment, where surface runoff can be very strong. Another point of active erosion is represented by the exposed walls of gullies and voçorocas, mainly in fluvial reaches subjected to talweg lowering. In a general sense, this study shows current evidence of erosional stability due to the ìntroduction of pastures as a predominant type of land occupation and to a series of erosion control procedures. Among these actions are terrace implantation, construction of small pits for runoff control, natural or induced reforestation by land owners. Despite these efforts, some erosion points remain chiefly in steeper country roads and trail stretches, in areas of concentration of cattle tracks (e.g., near cattle ponds), gullies or voçorocas exposed walls, and badly planned urbanization. The permanence of these erosion points demonstrates the necessity of a continuous monitoring of surface dynamics as well as a rapid and effective intervining measures of erosion and/or silting control.
