(Universidade Federal do Pará, 2013-11-06) SANTOS, Mateus Silva dos; OLIVEIRA, Dênio Ramam Carvalho de; http://lattes.cnpq.br/1324105476558186
The recovery and strengthening of reinforced concrete structures are increasingly common in Brazil, mainly due to the aging of structures built in the 60s and 70s of the twentieth century, which are close to reaching their lifetime. Added to this, factors such as the use of concrete with low strength, execution failures, improper use and lack of maintenance. Due to these factors that society should endeavor to enhance and / or restore these buildings, thus avoiding demolition of the same and even avoid fatal acidentes. This paper presents a case study that aims to recover a building that is abandoned for nearly two decades in the city of Rio Branco, Acre State. Currently, there are various techniques for strengthening reinforced concrete structure. Such as reinforcement through reinforced concrete jacketing, supplemented or enhanced with added armor, enhanced with application of metal sheets and profiles, reinforcing pillars reinforced with carbon fiber (PRCF), among other. In this work, the method adopted for recovery was enhanced by reinforced concrete jacketing. And for a better understanding of the methodology adopted work also presents details of the enhanced configuration adopted, constructive detail and executive procedures of the method adopted. In addition, the wrappers showing the active and resistant efforts before and after the booster.

(2013-03) PEREIRA, Patrícia Magalhães; LEMOS, Vanda Porpino; RODRIGUES, E.; FAIAL, Kelson do Carmo Freitas
Clay sediments from the municipalities Assis Brazil (Acre), were leached with solutions of sulfuric acid, humic acid and urea, to evaluate the retention capacity of molybdate in these materials and to investigate the feasibility of the adsorption processes at solid-solution interfaces. The materials were characterized from data of XRD, FTIR spectra, surface charge and chemical composition. The Langmuir isotherm models, Freundlich and Sips were used to fit the experimental data of adsorption. The minerals identified in the clay sediments were smectite, kaolinite, illite, quartz, albite, calcite and microclineo. The chemical modification leads amorphization of the modified sample with sulfuric acid and delamination along the plane 001 of the modified sample with urea. The settings defined by mathematical parameters (KL,Kf) of the adsorption isotherms, evaluation Ce vs. qe, pH vs. Qe, Qmax (sips) and Kd, indicated that the S10H15 sample is more efficient in the adsorption MoO42- ,with com qMax = 6.83 mg.

Análise espacial dos sítios monumentais do leste da Amazônia ocidental
(Universidade Federal do Pará, 2014-08-19) BARBOSA, Antonia Damasceno; SCHAAN, Denise Pahl; http://lattes.cnpq.br/9087840228167206
This study aimed to analyze the geometric enclosures located in the eastern state of Acre, using geoprocessing tools and considering environmental and cultural factors that could have influenced the decisions of social groups on the location and morphology of these archaeological sites. The approach of landscape archaeology was used, as well as GIS as an analytical tool. From the survey data of 419 geometric enclosures in eastern Acre State, the research investigated cultural patterns related to the morphology and configuration, location and orientation of sites, using statistical and methods of spatial analysis. The study concluded that patterned building techniques were used in the construction of the enclosures and their location took into account the proximity of water sources, soil types and elevation. Morphological characteristics were associated with the size and location of sites. The survey also found that most of the enclosures was constructed to mark the winter or summer solstice. Considerations were also made on the state of conservation of sites and challenges to the management of this heritage.

Avifauna do estado do Acre: composição, distribuição geográfica e conservação
(Universidade Federal do Pará, 2009) SILVA, Edson Guilherme da; SILVA, José Maria Cardoso da; http://lattes.cnpq.br/6929517840401044
The Brazilian state of Acre borders Peru and Bolivia, and is located in the lowlands of the southwestern Amazon basin, close to the foothills of the Andes, in a region considered to be biologically megadiverse. Despite this, the region is still relatively poorly‐known in scientific terms, and is considered to be a priority for further biological surveys. With the aim of contributing to the understanding of the bird fauna of southwestern Amazonia, the principal objective of the present study was to evaluate these three questions: (a) How many and which bird species are found in Acre? (b) How are the species distributed in the state? and (c) What is the conservation status of the resident species? These questions were evaluated through a number of different approaches: (a) a comprehensive review of the literature; (b) field surveys over a two‐year period, including the recording and collection of voucher specimens; (c) production of distribution maps for each taxon (including species and subspecies); (d) distribution of the taxa among the state’s three major interfluvia or subregions (east, central, and west); (e) identification of zones of contact and hybridization, based on the distribution of parapatric species within the state; (f) estimation of the potential distribution of the taxa within the state of Acre, based on the extrapolation of the area occupied by that of each ecological unit (phytophysionomy) in which they were recorded; (g) assessment of the conservation goals for each resident taxon; and (h) a gap analysis, based on the overlap of the potential distribution maps with the state’s protected areas. The gap analysis was conducted with reference to three different scenarios: (a) inclusion of all the protected areas; (b) inclusion of only the fully‐protected area exclusive sustainable‐use units and indigenous reservations; and (c) including fully‐protected and sustainable‐use units, but excluding indigenous reservations. The literature review and surveys (historical and current fieldwork) began in August, 2005, and continued until December, 2007. At the end of this period, a total of 7.141 records of birds had been accumulated for the whole of the state of Acre. Of these, 4.623 are of museum specimens, 2.295 (49,6%) of which were collected during the present study. The presence of 655 biological species was confirmed for Acre, distributed among 73 families and 23 orders. One direct result of the study was the addition of five new species to the list of Brazilian birds. Fifty‐nine migratory species were also recorded, including 30 (50,8%) Nearctic and 18 (30,5%) austral migrants, as well as 11 (18,6%) considered to be intratropical migrants. Forty‐four of the species recorded in the study are endemic to the Inambari endemism center. Of the 556 taxa of forest birds resident in Acre, 405 (72,8%) are found in all three subregions, 56 (10,0%) were recorded only in the western subregion, 30 (5.3%) in the eastern subregion, whereas only three (0,5%) were exclusive to the central area. At least six pairs of sister taxa have an allopatric distribution in the state, while 15 sets of taxa present a parapatric distribution. Two zones of secondary contact (east‐west) and two possible hybrid zones (east‐west) were identified within the state. The gap analysis revealed that, under scenario (a), 87,1% of the taxa were fully protected (100% conservation target), and 12% were considered intermediate, that is, partially protected, whereas only 0.8% were completely unprotected. In scenario (b), by contrast, only 0,6% of the taxa were fully protected, 97.6% were partially protected, and 1,8% were totally unprotected. In the third scenario (c), 73,5% of taxa were fully protected, 25,5% partially protected, and only 0,8% completely unprotected. The principal conclusions reached in the present study were: (a) the Brazilian state of Acre has an extremely rich bird fauna, although the number of species recorded should still increase as new surveys are conducted; (b) the Purus and Juruá rivers do not constitute physical barriers to the dispersal of most bird species resident in Acre; (c) the existence of zones of secondary contact not related to the state’s principal river systems supports the conclusion that factors other than physical barriers determine the present‐day pattern of distribution of some of the resident bird taxa in Acre; (d) that the number of “gap” and “partial gap” bird species in Acre is very low when the full protected area network is considered, although this number increases with the exclusion of indigenous reservations, and in particular, sustainable‐use conservation units; and (e) the only species completely unprotected by the state’s conservation network are those restricted to the campina and campinarana ecosystems of western Acre, which indicates a clear need for the establishment of one or more conservation units in this region with the specific aim of protecting this distinct type of ecosystem.

Beneficiamento local da produção extrativista e agroflorestal: o caso da Cooperativa Agroextrativista de Xapuri – CAEX
(2000-12) MICHELOTTI, Fernando
The main purpose of this paper is to elucidate the difficulties faced by Cooperativa Agroextrativista de Xapuri (Xapuri Agroextrativist Cooperative) to achieve its economical viability. Created in 1988 by the rubber tapers from Xapuri (Acre/Brazil), its case study provides an interesting example of an attempt to establish a local agro-extrativist production processing project. This project aimed to aggregate value by processing its members´ Brazil nuts production. The economical return of this iniciative, however, turned out to be less than the expected. Most of the studies dealing with the evaluation of these poor economical results identified as the main causes isolated socioeconomical factors happening in the production and comercialization process. Using conceptual framework of the evolutionary economy,this study pursues the identification of others structural problems as the primary causes leading to this bad economical return.

Dinâmica do carbono dissolvido no Rio Acre: variações espaciais e sazonais
(Universidade Federal do Pará, 2007) SOUSA, Eliete dos Santos; SALIMON, Cleber Ibraim; http://lattes.cnpq.br/4353834821288043; FIGUEIREDO, Ricardo de Oliveira; http://lattes.cnpq.br/2388049759708934
The main objective of this study was to study the dissolved carbon dynamics along a reach of the Acre River, evaluating the influence of Rio Branco city urban area and of the discharge from three of its tributaries (Riozinho do Rola, igarapé Judia and igarapé São Francisco), as well as the influence of hydrological seasonal changes. Samples were taken monthly, between December 2006 and September 2007, at five sites in Acre River and one site at the tributaries mouths. Each sample consisted of 1 liter of river/tributary water, which was submitted to filtering and aliquots withdrawn for dissolved organic carbon (DOC), dissolved inorganic carbon (DIC) and major ions (Ca2+, Mg2+, K+, Na+, NH4 +, HCO3 -, Cl-, SO4 2-, NO3 -, NO2 -, e PO4 3-) analysis. Electrical conductivity, pH, dissolved oxygen and water temperature measurements were also made. Mean annual pH in Acre River varied from 6.46 to 6.54 between sites and electrical conductivity presented mean values from 69.93 to 77.84 μS cm-1. In the tributaries, the mean annual pH ranged from 6.10 to 6.51 and electrical conductivity presented annual means from 54.08 and 153.03 μS cm-1. Na+ and Ca2+ were the dominant cations for both Acre River and its tributaries, while main anions were Cland SO4 2-. The mean annual DOC concentration in Acre River ranged from 4.62 to 5.17 mg l-1, with no significant difference among sampling sites. The tributaries’ mean annual DOC concentrations varied from 3.55 to 6.55 mg l-1. The concentrations were significantly higher in the high water period, with averages that ranged from 6.26 to 6.39 mg l-1 in Acre River sites. igarapé São Francisco was the only tributary that did not present differences between the seasons. Mean annual DIC concentration in Acre River ranged from 527.91 to 598.18 μM, with no significant difference among sampling sites. The higher concentrations were observed in the dry season, ranging from 816.31 to 998.52 μM. Mean annual DIC concentration in the tributaries ranged from 248.54 to 986.50 μM. Mean annual CO2 partial pressure (pCO2) in Acre River sites ranged from 3559 and 4059 ppm, with no significant differences among sites and with higher values in high waters. Based on these results, we conclude that the dissolved carbon dynamics in Acre River have not presented significant variations due to the tributaries discharge or due to the sewage discarded. On the other hand, hydrological seasonal changes are the most important drivers for changes in carbon dynamics.

Estrutura e impacto da expansão da agroindústria canavieira sobre o mercado de terras no estado do Acre, Amazônia ocidental – Brasil
(Universidade Federal do Pará, 2015-05-11) GOMES, Elói Biquer Silva Rosa; CAVALCANTI, Francisco Carlos da Silveira; http://lattes.cnpq.br/3017141149020182
This study deals with the question of the market of rural land in the Brazilian Amazon, for which was selected a specific region (the Lower Acre) as a case study. The choice of this area is due to the fact that it is developing and expanding heavily the agricultural activities with emphasis on the production of sugar cane in this region. This thesis aims to study the impact of the expansion of sugarcane on the market of rural land in the Region of Low Acre in the period 2007 to 2013. We analyzed the impact on the variation in land prices, the effects on the land use of the main food crops (rice, beans, corn and cassava) and the fluctuations of the price of ethanol practiced in the state of Acre. We used for this study the analytical database of UNICA, IBGE, FNP/Agrianual - which is a database that provides information on selling price of land for crops, pastures and prices of leases by states and regions in Brazil. The study allows us to conclude that in spite of the progress of the area occupied by the cultivation of sugar cane in the region, there has been a reduction of land occupation specifically for crops of beans and rice, but, on the other hand, there has been a considerable increase in the plantation areas of cassava and maize. The situation is quite worrying when it comes to the market of rural land in the region, especially after the start of agricultural activities of planting of sugar cane. There was a considerable enhancement of agricultural land, in the first years of the activities of the plantation. The prices in the region of Low Acre became to be one of the most expensive in the country, only behind the State of Amapá. The land designated for the pasture had higher valuations. This occurred because the areas of pasture are strongly linked to the activities of the plant of alcohol in the region. The agribusiness leased land that was reserved for pasture and the ranchers began to acquire/look for new areas for the creation of cattle. This increased demand for new land meant that they valorize above the national average. Consequently, this process has a major impact on the environment, affecting mainly the deforestation. The study showed that there was an increase in the rates of deforestation not only in the region, but throughout the State of Acre, including in areas such as environmental conservation, Extractive Reserves and indigenous lands. And finally, this study allows us to conclude that the hypothesis that the local production of ethanol would tend to influence the reduction in the price of alcohol in the State has not been confirmed. Paradoxically, even with the entry into operation of the plant (already more than three years), Acre continues to be State with the highest price of ethanol in the country, and the prospect is that even the increase of production in the upcoming years should not result in reduction of the price of ethanol because the trend is that the scenario in the domestic and international markets will remain turbulent in the coming years.

Um estudo sobre a migração de japoneses para a Amazônia peruana e sua continuação para a Amazônia brasileira
(Universidade Federal do Pará, 2014-05-29) SILVA NETO, Francisco Rodrigues da; ARAGÓN VACA, Luis Eduardo; http://lattes.cnpq.br/2713210031909963
The arrival of Japanese immigrants to Peru, aboard the ship Sakura Maru, in 1899, to work on the farms of the Peruvian coast, coincides with the heydays of rubber exploitation in the Amazon, which made this region attractive to migrants who did not remain in these farms. In the same year of the arrival of the ship Sakura Maru, 91 of these immigrants moved to the current department of Madre de Dios south of the Peruvian Amazon. After the cycle of exploitation of rubber, many Japanese immigrants remained in the Amazon and in Madre de Dios they settled around Puerto Maldonado, emerging a thriving Japanese community that remains up today. At the time of rubber exploitation some Japanese migrated to the current state of Acre (Brazil), called Peru kudari (those that descended from Peru), but few settled, spreading themselves, after the collapse of the rubber economy, to other places of Brazil and other countries. Thus, this thesis aims to demonstrate that migration of Japanese to the department of Madre de Dios in the Peruvian Amazon, and the emergence and consolidation of a Japanese community in Puerto Maldonado (capital of this department), were caused by three main factors: 1 ) a continuous policy in favor of Japanese immigration to Peru during the first decades of the twentieth century aimed to provide labor to the farms of sugar cane and cotton of the coast; 2) Involvement of Japanese immigrants in economic activities during the expansion of rubber exploitation in the Peruvian Amazon; and 3) Strengthening of these activities after the collapse of the rubber economy to ensure the supply of products required for the remaining population, including replacing of products imported or supplied by large companies. These factors were not found among Japanese who moved to Acre (Brazil), thus not getting the setting of Japanese communities that remained until today. The sources used in this study were composed of literature on international migration, data from the Peruvian and Brazilian censuses, newspapers of the time, diplomatic documents, and provincial reports, among others. The thesis is a study of historical demography using quantitative and qualitative data, in the quest to understand the historical process of the research object, in order to explain the developments that occurred in the communities of Japanese immigrants both in Madre de Dios (Peru) and Acre (Brazil).

Hidatidose policística no Estado do Acre: contribuição para o diagnóstico, tratamento e prognóstico dos pacientes
(Universidade Federal do Pará, 2010-06) SIQUEIRA, Nilton Ghiotti de; PÓVOA, Marinete Marins; http://lattes.cnpq.br/2256328599939923
The echinococcosis is a zoonosis whose etiological agents are nematodes of the genus Echinococcus. There are five species of Echinococcus, two of them, E. oligarthrus (Diesing, 1863) and E. vogeli (Rausch & Bernstein, 1972) only occur in neotropical areas. The echinococcosis by E. vogeli causes multiple hydatid cysts, mainly in the liver of intermediate hosts, of which one is the human being. The lack of knowledge about the disease makes the diagnosis is delayed or even misleading. The lack of systematic information on treatment is also difficult to assess the results and prognosis of patients with peritoneal and hepatic lesions caused by E. vogeli. Here we describe the clinical features of patients, we propose a radiological classification protocol used in the classification of alveolar echinococcosis (E. multilocularis "PNM" Classification, Kern et al., 2006), which was also suitable for polycystic echinococcosis (E. vogeli) and describe a therapeutic option for the treatment of hydatid disease which previously had only been used for cases of cystic echinococcosis (E. granulosus, PAIR-Puncture, Aspiration, Injection, Reaspiration, Brunnetti et al., 2001). A prospective cohort study was initiated in 1999 and by 2009 included 60 patients. We describe the main symptoms and signs: pain in upper abdomen (65%) and hepatomegaly (60%) and patients were classified according to the "PNM" classification and submitted to three therapeutic modalities: (i) chemotherapy with albendazole at a dose of 10mg/kg/day, (ii) surgical removal of cysts or (iii) percutaneous puncture of the cysts- PAIR. After exclusion of two cases, due to inadequacy of the research protocol, the groups were distributed as follows: treatment with albendazole: n = 28 (48.3%, 28/58), surgical therapy: n = 25 (52.1%; 25/58) and PAIR: n = 5 (8.1%, 5 / 58). The results were stratified according to outcome of therapy: "Cure", represented by the disappearance of lesions after clinical or surgical treatment, "clinical improvement", defined as asymptomatic patients without weight loss and physiological functions preserved, "No Improvement" included patients who remained symptomatic, "Death" and "No Information", the monitoring did not allow a conclusion about the outcome. The three treatment groups together demonstrade lethality rate of 15.5% (9 / 58), "no improvement" 1.7% (1 / 58), "clinical improvement" in 40.0% (23/58) and "cure "in 32.8% (19/58). Regarding the outcome "death", there was no difference between therapies with albendazole or surgical treatment with 4 (14.2%) and 3 (12%) deaths respectively, but in the first group, albendazole, the outcome "cure" was 4.3% (1 / 23) and "clinical improvement" 74.0% (17/23), whereas in the "surgery" to "cure" represented 71.0% (17/24) and "clinical improvement" 16.7 (4 / 24). Therapy "PAIR" was associated with a lethality rate of 40% (2 / 5), cure in 20% (fifth) and clinical improvement in 40% (2 / 5). The "PNM" classification was useful to indicate such therapy in cases of polycystic hydatid disease. In conclusion, in the series studied surgical therapy has better results in the clinical therapy on the outcomes "cure" and "clinical improvement". The treatment for PAIR needs further studies.

ICB/PPGBAIP Estudo da ocorrência e perfil de suscetibilidade aos antimicrobianos de Staphylococcus aureus isolados de pacientes e profissionais de saúde na Unidade de Terapia Intensiva de hospital público de Rio Branco-AC
(Universidade Federal do Pará, 2011-02-07) LAVIOLA GARCÊZ, Poliana Torres; LOUREIRO, Edvaldo Carlos Brito; http://lattes.cnpq.br/2685418720563351
The nosocomial infection is a serious public health problem worldwide, mainly in patients admitted to the Intensive Care Unit, which are subject to greater risk due to the severity of clinical symptoms, constant use of broad spectrum antibiotics and frequency of use of invasive procedures. Staphylococcus aureus is a major pathogen that colonizes healthy individuals and is also responsible for infections in hospitalized patients. This study aimed to identify the resistance profile, main sites affected by infection and possible risk factors associated with infection or colonization by S. aureus isolated from patients and healthcare professionals from the Intensive Care Unit of Hospital Emergency and Emergency, Rio Branco (HUERB) – Acre. We developed a cross-sectional study, conducted between January to August 2009. To search for carriers, biological samples were collected from microbiota of patients and professionals and professionals hand washing. For a survey of cases of patients with nosocomial infection were collected biological samples from sites suspected of being affected, 72 hours from the date of admission until discharge, transfer or death. Of the 62 patients enrolled in the study, 19.3% were carriers and 6.4% developed nosocomial infections by S. aureus, and 35 professionals, 28.6% were carriers of S. aureus. It was the second most bacterial species isolated from patients, and was the fifth most isolated from cases of nosocomial infection. There was no statistical evidence for the variable state of coma, use of invasive procedures and state of carrier patient are considered risk factors for acquiring nosocomial S. aureus in this study. The anatomical sites affected by IH by S. aureus were the respiratory tract ( n=2), followed by blood (n=1). The sample catheter tip was responsible for one insulated. One (1.6%) patient developed IH by MRSA, and 5 (8,1%) patients and 2 ( 5.7%) professionals were MRSA carriers, low occurrence as it relates to the results of the rest of Brazil and world. We also emphasize the incidence of MRSA over MSSA and low antomicrobial resistance of MRSA demonstrating that the UTI-HUERB, the IH S. aureus does not constitute a public health problem. There were no isolates of S. aureus resistant to vancomicina, wich can be considered a therapeutic option for cases of IH by MRSA. It is worth emphasizing the importance of this study in Acre State, for being the first of its kind in the UTI, involving S. aureus and MRSA.

Influência do método de síntese no processo de pilarização com titânio de uma esmectita da região amazônica
(2006-12) GUERRA, Denis de Jesus Lima; LEMOS, Vanda Porpino; ANGÉLICA, Rômulo Simões; AIROLDI, Claudio
Smectite clays of the State of Acre, Brazil, were used for the pillarization process. The natural and pillarized matrices were characterized by X-ray diffraction, Fourier transform infrared spectroscopy (FTIR), thermal analysis, scanning electron microscopy, energy dispersive spectroscopy and textural analysis. The titanium pillarized solutions Ti(OC2H5)4 and TiCl4 were analyzed by FTIR. The intercalation ion was obtained by reacting Ti(OC2H5)4 with HCl (HCl/Ti ~ 1) and TiCl4 with ethanol (Ti/clay ~ 25 mmol Ti/g). The notronite intercalation was carried out using two methods: with dropwise hydrochloric acid in titanium ethoxide solution, and using titanium tetrachloride, kept under vigorous stirring at 25 °C for 3 h and calcination at 450 °C and 600 °C. The X-ray diffraction results of the pillarization process show an increase (15.30 Å to 18.76 Å) in the basal spacing of the natural clay and in the specific surface area (44.37 m2/g to 188.72 m2/g) The thermal stability of the natural clay was improved by the pillarization procedure.

Inquérito com paracoccidiodina em cinco cidades do Estado do Acre
(Universidade Federal do Pará, 2011-09-30) FIGUEIREDO, Mediã Barbosa; ISHAK, Ricardo; http://lattes.cnpq.br/5621101706909450
Paracoccidioidomycosis constitutes an important public health problem in Latin America. In Brazil, this disease is less frequent in North and Northeast regions, predominating the endemic areas in the Southeast. Despite the physiographic conditions of the North region favoring the development of Paracoccidioides brasiliensis, even so, the case reports are scarce. Perhaps this is due to the little consideration of deep mycoses about the differential diagnosis of chronic medical conditions, justified by the fact that the region is not considered endemic. With the objective of describing the prevalence of paracoccidioidomycosis in five cities of Acre, a cross-sectional population-based study was conducted, through a survey with the paracoccidioidin intradermal. The reading of the intradermal test was performed within 24 and 48 hours, being considered reactors the people with hardened areas of 5mm or more in diameter. Four hundred thirty-nine (439) people were studied and paracoccidiodomycosis-infection in the 48-hour reading was 41.2%. The findings of this study indicate that P. brasiliensis infection causes a considerable number of people in the study area to get infected, and therefore future clinical-epidemiological and mycological studies should better clarify the natural history of mycosis in this region.

Mercury in fish and sediment of Purus River, Acre State, Amazon
(Universidade Federal do Pará, 2016-09) CASTRO, Nathália Santos Serrão de; BRAGA, Camila Margalho; TRINDADE, Paulo Arthur de Abreu; GIARRIZZO, Tommaso; LIMA, Marcelo de Oliveira
Core subject: To quantify the Hg content of sediment and fish collected along the Purus River (Acre State, Amazon) in order to identify if those samples could be a potential route of Hg exposure to the population of Manoel Urbano (a riverside community). Methods: The total mercury (THg) was quantified using the Cold Vapor Atomic Absorption technique. Results: We collected 06 samples of sediment and 264 samples of fish. The Hg in sediments ranged between 0.038 and 0.065 µg.g–1.The results indicate that sediment is in agreement with “uncontaminated” Amazonian rivers. The carnivorous species presented the highest level of Hg on muscle (mean 0.927 µg/g–1), followed by piscivorous (mean 0.873 µg.g–1), planktophagus (mean 0.566 µg.g–1), omnivorous (mean 0.533 µg.g–1) and detritivorous (mean 0.176 µg/g–1). Fourty four percent (44%) of the total species collected presented mean levels of THg on muscle, a percentage greater than the threshold recommended by WHO. Conclusion: Some species may be a route for Hg exposure. The sediment is within the normality. The authors suggest that other factors, such as culture and society, should be considered for future researches in order to promote the population healths.

Nutrientes (K, P, Ca, Na, Mg e Fe) em sedimentos (solos aluviais) e cultivares (feijão e milho) de praias e barrancos de rios de água branca: a bacia do purus no estado do Acre, Brasil
(2009) MARTINS, Milta Mariane da Mata; COSTA, Marcondes Lima da
The present research highlights the macronutrient abundance in the sediments of beaches and cliffs and cultivates in the river Purus and flowing, southwest of Amazon. The concentrations found in leaves and bean seeds and corn leaves reflect the mineralogical and chemical nature of those rich sediments in K2O and Na2O, which are formed by smectite, illite and K-feldspar. The factors of transfer of the elements in the corn leaves and bean (Ca>K>Na) and bean seeds (Na>K>Ca) demonstrate that the nutrient needs of the cultivate were found appropriately in the sediments (soils) of the beaches and cliffs.

Políticas de integração na fronteira trinacional Brasil, Peru e Bolívia
(Universidade Federal do Pará, 2012-05-28) OLIVEIRA, Maria do Socorro Soares de; SIMONIAN, Ligia Terezinha Lopes; http://lattes.cnpq.br/6620574987436911
International borders are highly complex spaces, characterized by great diversity of ethnicities and multinational identities. In the South western Amazon there is a strategic geopolitical area, formed by the trinational frontier between Acre (Brazil), Madre de Dios (Peru) and Pando (Bolivia). Despite legitimate national security concerns, justifying the creation of a special territory along the international boundary, there is no systematic policy addressing regional specificities, from either an economic or citizenship standpoint. The physical integration of Brazil, as a core issue regarding both the national interest and the fight against illicit activities, attaches a new strategic role to international boundaries. Interest for boundaries is gaining a new momentum out of these issues, making cross-border relations a priority in international relations. Indeed, the search for new meaning to the Brazil’s interactions with its neighboring countries, has been redirecting the action of the Brazilian State, with reflections on South America’s geopolitics. The aim of this study is to analyze regional integration policies and actions in the context of the development process taking place in a trans-frontier area under the trinational jurisdiction of Brazil, Peru and Bolivia.

This study aimed to demonstrate the design and verification of calculating the NBR 6118 (ABNT, 2007) with their geometric characteristics, encasing armor, armor, and buckling resistance of the compression pillars centered pillars of reinforced concrete, with the major bibliographic techniques for structural reinforcement of concrete columns for old buildings, identifying the main methodologies and techniques used in Brazil and presenting the strengths and weaknesses of each technique: concrete jacketing, steel profiles, steel plate glued, blanket / carbon cloth , aramid and glass and polymers reinforced with carbon fiber (CFRP). The pillars with increased rectangular cross section, with added frame and concrete, being the most common and practical technique presents difficulties in ancient works, usually due to architectural need to remain as true to its original form. Justifying the need for knowledge of the various techniques described in this work structural reinforcement with increased resilience, without any substantial increase in the cross section of the pillars and objective analysis of the proposed enhancement through the design calculations, program - PDOP 2.0 and parameters for calculating the NBR 6118 (ABNT, 2007). The results obtained by comparative analysis of reinforcement performed in the case study "revitalization of the old house" - with respect to the analysis of rectangular pillars subjected to bending oblique shear and torsional as the NBR 6118 (ABNT, 2007) using the program optimized design of columns - PDOP 2.0 - indicated that the reinforcement technique was studied efficient because all reinforced parts had a greater bearing capacity than the original pillar without strengthening.
