Geologia e Mineralogia do Pegmatito Estanífero Cascavel, Mina Bom Futuro, Rondônia

A mina Bom Futuro situa-se na região centro-norte de Rondônia e inclui dois morros denominados de Palanqueta e Bom Futuro e as áreas aplainadas adjacentes. As principais lavras de extração de cassiterita ocorrem nos placeres circunvizinhos ao morro Bom Futuro, bem como nos depósitos primários situados no próprio morro. Esses depósitos primários restringem-se aos corpos de pegmatito formados em pelo menos dois eventos distintos. O pegmatito Cascavel pertence ao evento mais antigo e é composto por uma lente principal e um enxame de diques, veios e vênulas com atitude geral NNW/35oENE. Os corpos são maciços ou zonados, sendo que na lente principal foram reconhecidas três zonas distintas, sob a forma de leitos subparalelos entre si e com as paredes da lente. Do muro para o teto tem-se: zona do quartzo e topázio, zona do feldspato alcalino e Li-mica e zona granítica. Os minerais principais do pegmatito Cascavel são quartzo, feldspato alcalino (microclínio pertítico), topázio e Li-mica e os minerais subordinados ou acessórios são cassiterita, sulfetos (esfalerita, calcopirita, pirita, galena e estanita), zircão, monazita, wolframita, uraninita, columbita-tantalita e rutilo niobífero. O pegmatito Cascavel é do tipo complexo e pode ser incluído na família LCT dos pegmatitos a elemento-raro. O pegmatito Cascavel é de natureza subvulcânica e mostra relações espacial e temporal com os granitos peraluminosos tardios da Suíte Intrusiva Granitos Últimos de Rondônia.

Evolução temporal das definições de síndrome do desconforto respiratório agudo

OBJECTIVE: to review the evolution of acute respiratory distress syndrome (ARDS) definitions and present the current definition for the syndrome. DATA SOURCE: a literature review and selection of the most relevant articles on ARDS definitions was performed using the MEDLINE®/PubMed® Resource Guide database (last ten years), in addition to including the most important articles (classic articles) that described the disease evolution. DATA SYNTHESIS: the review included the following subjects: introduction; importance of definition; description of the first diagnostic criterion and subsequently used definitions, such as acute lung injury score; definition by the American-European Consensus Conference, and its limitations; description of the definition by Delphi, and its problems; accuracy of the aforementioned definitions; description of most recent definition (the Berlin definition), and its limitations; and practical importance of the new definition. CONCLUSIONS: ARDS is a serious disease that remains an ongoing diagnostic and therapeutic challenge. The evolution of definitions used to describe the disease shows that studies are needed to validate the current definition, especially in pediatrics, where the data are very scarce.

Resenha: Um pouco do legado das formulações de Clausewitz sobre a guerra e a política

Carl von Clausewitz (1780-1831) foi um generalprussiano que teve como um de seus principaislegados uma obra clássica, “Da guerra”, umareferência obrigatória sobre o fenômeno bélico.Escrita provavelmente entre 1812 e 1831, foipublicada postumamente graças ao esforço de suamulher Marie von Clausewitz (ARON, 1986a); foi oprincipal resultado de experiência e enormeelaboração de vasta obra do general prussiano,soldado do exército prussiano desde 1792 ecombatente nas guerras napoleônicas semprecontrariamente à França comandada por NapoleãoBonaparte. mesmo quando a Prússia se aliou aNapoleão após ser derrotada. Naquele momento,Clausewitz renunciou à sua patente como oficial noexército prussiano e se alistou no exército russo;desempenhou papel importante na retirada daPrússia da aliança pró-França quando o GrandArmée napoleônico bateu em retirada em suamalsucedida campanha na Rússia. Reintegrado aoexército prussiano e à sua patente, Clausewitzparticipou de teatros de operações secundários nasações decisivas até a derrota definitiva deNapoleão; suas convicções antinapoleônicas lhecustaram desconfiança e um preço muito caro: apartir de então, sua ascensão até o generalatorenderam-lhe posições secundárias eadministrativas sem comando de tropas, dentreelas, a direção da Academia Militar de Berlim. Nofinal deste contexto foi escrita “Da guerra”.

Previsão do comportamento de estruturas de contenção atirantadas utilizando o software FTOOL

Population growth, together with the gradual social ascent in Brazil, reflects at the growing need for better use of urban spaces. In this context, the amount of new buildings to meet the demand in property market, the needs for creating new roads and highways, among others, make the use of geotechnical works and, more specifically, retaining walls, more and more common. One of the simplest solutions for underground works is the use of retaining structures using tie back walls for soil support, therefore, the present work deals with this kind of structures. This paper proposes the use of FTOOL software testing in predicting deformations in tie back walls, by comparing simulations of the presented model to a real and measured deformation case in Guabirotuba Formation (PR). The results showed the importance of defining the parameters such as stiffness and curtain geometry, as well as the definition of representative loads acting on it. Also, it was pointed out that the passive response of the steel rods depends on the horizontal displacement of the wall. The study concluded that the program generates very representative results when compared to field data and seems to be a promising tool for tie back structures displacement predictions

Viabilidade do aproveitamento de resíduos de madeira para produção de móveis

The need to use waste from wood processing industry grows due to environmental demands imposed by laws, so like the need to introduce more competitive products in the market (it means better quality and acceptable cost) who must submit by the rational use of raw material, usually turning waste to sub products, what adds higher value for that. To this research, specific case from Ribon Company, located on Camaçari, Bahia-Brazil, has been studied. It is a treated wood producer. Bulk of monthly wood logs there is 70 m3. Its yield is 71,43%, where bulk of generated waste is monthly 20m3. As an exploitation way from generated waste, it has been suggested some options like: erosion protection to specific areas, a wildlife shelter as an henhouse etc, recreational articles, coal, linings, treadmills. However this research will give focus to the furniture design made of waste. As a conclusion, there is very much need to assign new utilizations to that sub used materials, since there is significant amount to increase company’s productive yield

A experiência da saúde coletiva na formação profissional: retrato da extensão universitária

The guidelines of National Curriculum for Dental courses highlights the necessity in providing for the professional the ability to analyze and assess community’s problems and needs, and to create solutions for the society. The continuing education may be considered a useful tool for the teaching and learning because it favors the diversification of learning environments, which allows the insertion of undergraduate and graduate students into the real scenarios. This current study aimed to assess the Public Health projects and programs of the UNESP – Araçatuba Dental School, by describing the interaction experiences between faculty and health services in the professional career development. Historical, documentary and descriptive searches were performed based on the faculty archives such as official documents, reports, databases from the Pro-rector of continuing education and published papers in the period between 1964 and 2011. The following experiences were noted: the Extra-Muro Dental Service (SEMO), established in 1964, that focused in providing dental treatment to the rural population, highlighted the social inclusion of discriminated society groups since that time. In 1972, this service was expanded to several specific populations living in the urban areas. In the '60s, many educational campaigns were performed as homemade water filter and construction of wells and septic tanks which demonstrate the concern with the determinants of healthdisease process. At that time, the campaign of fluoridation of public water supplies in several counties started as Araçatuba, Birigui, Penápolis, Guararapes, Valparaíso and so on. The Campaign of “Good Teeth” from the '70s became wider over time and it was transformed in the "Oral Health Education Program" and it was continuously developed in all public schools of Araçatuba and some neighboring towns, benefiting children aged from 6 to 10 years-old. Several epidemiological studies of caries, periodontal diseases, malocclusion and fluorosis were conducted in cooperation with local governments, and counted with the participation of undergraduate and graduate students. Pereira Barreto – SP was the precursor city in Brazil to carry out fluorosis study. Currently, 12 projects of Public Health from the Institution of Higher Education in the Pro-rector of continuing education are being developed. The concern in qualifying the human resources in health is confirmed with the development of training courses and workshops for professionals, highlighting the training for people enrolled in the Family Health program; Community Health Agent training - Solidarity University, and Municipal Health Counselors training. The Graduate Program in Social and Preventive Dentistry, created in 1993, has an important role to train several professionals for the Unified Health System, and provides education to create researchers, professors and administrators, and enucleates research groups in several Brazilian states. In all activities showed herein, a dynamic participation of undergraduate and graduate students has been observed, and several books, guidelines, articles, brochures and booklets have been published as a result of the continuing education activities.. It was concluded that different projects and programs have been developed by the Public Health of UNESP –Araçatuba Dental School, which allow the exchange of experience between the university and health services, and benefit all participants enrolled in these activities.

Mapeamento de ocorrências de eventos perigosos no município de Santos SP: integração com dados de vulnerabilidade socioambiental

This study is based on the mapping of occurrences associated with social vulnerability and natural risks, which refer to the resilience of populations and territories, regarding natural hazards associated with the functioning of natural systems (eg, earthquakes, flood, mass movements). According to UNISDR (2014), the state of São Paulo is a reference in working with Urban Resilience and Disaster in the Resilient Cities Campaign (2014), considering the high investment in Risk Areas Mapping and Public Education Campaigns implemented by the Civil Defense. Thus, this study aims to mapping the occurrence of events related to Tree Falls, Erosion, Landslides, Irregular Housing, Rocky Blocks Falls, Wall Falls, Unroofing and Irregular Construction, attended by the Civil Defense in the city of Santos, São Paulo State, from 2011 to 2014. Thereafter, correlated analyzes to the Environmental Vulnerabilities were generated. The Environmental Vulnerability databases used in this dissertation compose the results of the CNPQ Project - Environmental Vulnerability Mapping of the State of Sao Paulo - Brazil: a methodological contribution of Freitas (2013) and Bortolettoet al (2014), with information collected from the 2010 Census (IBGE, 2010), on a census sectors scale. The adopted methodological procedure involves document analysis followed by data integration in Geographic Information System, through algorithms analysis and mapscrossing.The results obtained in Maps of Social and Environmental Vulnerability Occurrences presented areas of High or Very High Vulnerability. The main variables obtained with such characteristics are Irregular Housing, Landslides and Rocky Blocks Falls, which was associated with hilly terrain formations, with slopes above 30%. To the areas of Medium, Low and Very Low Vulnerability were associated the variables Tree Falls, Wall Falls, Erosion, Unroofing and Irregular Construction, which are spatially distributed without an...
