Esta Dissertação de Mestrado em Serviço Social tem como objetivo fazer uma reflexão sobre a prática interdisciplinar entre assistentes e psicólogos que atuam nos Centros de Referência de Assistência Social do município de Abaetetuba. O Município está localizado á aproximadamente 80 km da capital do Estado do Pará e tem aproximadamente 139.000 habitantes, conforme o último censo IBGE. Desde 2005 vem implementando as diretrizes da Política Nacional de Assistência Social de 2004. A Nova Política Nacional de Assistência Social, por meio de suas diretrizes e principais objetivos visa a consolidação dos processos de descentralização da gestão. Institui um novo modelo organização dos serviços socioassistenciais, unificando conceitos e procedimentos em todo território nacional através do Sistema Único de Assistência Social que, por sua vez, estabelece padrões para a execução dos serviços, para a qualidade no atendimento, e define indicadores de avaliação e resultado. A interdisciplinaridade ainda é considerada um conceito em construção, entretanto nesta realidade configura-se como uma relação de reciprocidade de mutualidade que pressupõe uma atitude diferente a ser assumida frente aos problemas de conhecimento, isto é substituir a concepção fragmentária pela unitária do ser humano. Esta atitude, não poderá ser preconceituosa, mas aberta onde todo conhecimento torna-se importante, pode ser fundamentada na intersubjetividade e interação entre os saberes, mas não pode estar desligada do contexto onde ela ocorre. A atuação prática interdisciplinar no Centro de Referência de Assistência Social, bem como em outros programas projetos e serviços desta política é incentivada, mas na realidade do município aqui pesquisado observou-se que existem muitos obstáculos e desafios para o exercício desta prática. Desde o não cumprimento das normatizações que regulamentam a Política de Assistência Social até a superação das condições precárias nas relações de trabalho, tanto no que diz respeito ao vínculo, quanto às condições físicas e materiais dos espaços, passando pela necessidade de implementação de gestão voltada a qualificação e valorização dos recursos humanos inseridos no SUAS.

This completion of course work has as its object of study the Bauxite Province of Paragominas regarded as the richest Amazon bauxite province and whose genesis is related to laterization processes responsible for the formation of mineral deposits of the Rondon Alumina Project, designed to assess areas in the southeast of Pará State, for mineral resources exploration of bauxite, which is the main source of aluminum in the country. Located in the region of Rondon do Pará - PA, the study area is geologically inserted in Lithostratigraphic Unit called Cobertura Laterítica Matura (Mature Lateritic Cover), formed by alteration of paleotropics Cretaceous siliciclastic rocks, and its geomorphology corresponds to a broad plateau with displays of representative profiles of the processes that acted in the region. In this context, the present research aims to characterize the geological evolution of the laterite profile, with detailed studies in the area, geological description of the formations from the bauxite surfaces, and mineralogical composition litochemical of different horizons that were correlated and deployed in an evolutionary model compatible with its traits. The data collected during the analysis subsidized metalogenetic understanding of the processes that acted in the enrichment of aluminum and iron as well as the redistribution of the latter modified profile. The results and information were embodied in the form of geological characterization of the different constituents of mineral associations of bauxite horizons, similarities or differences in both textural and structural aspects, in order to propose a evolutionary model with retaken of gibbsitization processes

Climate variability and therefore the rainfall is often cited today, in times to speak of "global change", "global warming", "anthropogenic disasters," among other terms related to climate issues, which may cause floods and disasters that affect entire regions. In this sense, the seasonal rainfall and its extremes in the basin of Ivaí river, which has a drainage area of approximately 36 000 km2, covering a length of 680 km, located in the State of Paraná between coordinates 22 º 54'S 25 ° 44'S and 55 44'W to 52 º 42'W, were analyzed. Influence of rainfall for the man occupation is undeniably important, not less important is the role that this issue poses to the climate abiotic and biotic environment, because the dynamic relations between the fauna and flora is directly related to the availability of water in system (in this case, rain). The methodological procedures used during the research focused on statistical analysis of rainfall series daily, monthly and yearly, provided by the Superintendence of Water Resources Development and Environmental Protection Agency - SUDERHSA, an agency linked to the government of Parana. The analysis period chosen was from 1975 to 2005, with 38 stations for data collection, distributed evenly across the search area. The standard rainfall in the basin is explained mainly by convective processes in the summer (wet season) and front system causing more homogeneous rainfall over the basin (dry season). What is well marked is the occurrence of maximum rainfall in the years 1983 and 1997 (El Niño) and minimal in the years 1977, 1985 and 1988 (La Niña). Finally, although the study area have undergone a significant change in your landscape for over thirty years, this study indicates no significant interference in rainfall.

Two of the major problems caused by construction activity are the production of construction and demolition waste (CDW) and the exploitation of mineral resources, causing big impacts on the environment. Therefore, the recycling has been shown as an alternative to mitigate the harmful effects of waste on the urban environment and prevent the exploitation of new raw materials. This course work aims to study the behavior of recycled aggregates from Vale do Paraíba in concrete and mortar. Initially, it presents the definitions of recycled aggregates according to CONAMA Resolution No. 307/2002, the aggregate settings for concrete and mortar (such as the grain size, its origin and density, and the characterization parameters according to ABNT), and the definition of ACI method of concrete mix design. Afterwards, it presents the characterization of materials separated by assays. After that, it shows the theoretical concrete proportioning applying the ACI method and experimental concrete proportioning. Then, the analysis of results is performed to finally conclude that the materials provided can't be used to replace natural aggregates because they cannot have the same performance. With the studies, it could be observed that the recycled aggregate presents a great complexity and diversity in origin, therefore the form how the material should be handled requires great care

The U.S. Geological Survey (USGS) is committed to providing the Nation with credible scientific information that helps to enhance and protect the overall quality of life and that facilitates effective management of water, biological, energy, and mineral resources (http://www.usgs.gov/). Information on the Nation’s water resources is critical to ensuring long-term availability of water that is safe for drinking and recreation and is suitable for industry, irrigation, and fish and wildlife. Population growth and increasing demands for water make the availability of that water, now measured in terms of quantity and quality, even more essential to the long-term sustainability of our communities and ecosystems. The USGS implemented the National Water-Quality Assessment (NAWQA) Program in 1991 to support national, regional, State, and local information needs and decisions related to water-quality management and policy (http://water.usgs.gov/nawqa). The NAWQA Program is designed to answer: What is the condition of our Nation’s streams and ground water? How are conditions changing over time? How do natural features and human activities affect the quality of streams and ground water, and where are those effects most pronounced? By combining information on water chemistry, physical characteristics, stream habitat, and aquatic life, the NAWQA Program aims to provide science-based insights for current and emerging water issues and priorities. From 1991-2001, the NAWQA Program completed interdisciplinary assessments and established a baseline understanding of water-quality conditions in 51 of the Nation’s river basins and aquifers, referred to as Study Units (http://water.usgs.gov/nawqa/studyu.html).
