14. O instituto de coimbra e a análise química de águas minerais em portugal na segunda metade do Século XIX
O Instituto, journal published by the Institute of Coimbra (IC), an academic society founded in this city in 1852, contains many articles on hydrology and chemical analysis of water for human consumption, written by well-known Portuguese chemists and physicians. Based on these papers, we analyse the evolution of hydrology in Portugal throughout the second ha

15. Controle na distribuição das lateritas e saprolitos de alto teor no depósito de níquel laterítico do Jacaré, Distrito de Carajás, Brasil
The Jacaré world class nickel lateritic deposit (495Mt @ 1,19% Ni) is positioned about 52 Km NNE straight line from São Félix do Xingu/PA State - Carajás Mineral Province. The deposit occurs in essentially dunitic and gabbroic rocks magmatically layered with subordinated peridotites and pyroxenites levels. The saprolitic zones host the main Ni ores and t

16. Modeling the potential distribution of the invasive golden mussel Limnoperna fortunei in the Upper Paraguay River system using limnological variables.
The invasive golden mussel, Limnoperna fortunei (Dunker, 1857), was introduced into the La Plata River estuary and quickly expanded upstream to the North, into the Paraguay and Paraná rivers. An ecological niche modeling approach, based on limnological variables, was used to predict the expansion of the golden mussel in the Paraguay River and its tributarie

17. Evolução magmática, alteração hidrotermal e gênese da mineralização de ouro e cobre do Palito, Província Aurífera do Tapajós (PA) / Magmatic evolution, hydrothermal alteration and geneseis of gold-copper mineralization at Palito, Tapajós Gold Province (PA)
The Palito porphyry type copper-gold deposit is located in the central region of the Amazonian craton, in the Tapajós Gold Province (TGP), in an area that is dominated by intermediate to felsic granitic and volcanic rocks of late Paleoproterozoic age. Three lithotypes make up this deposit. The Palito Granite, with porphyritic features, is the host rock for

18. Estudo da remoção de manganês de efluentes de mineração utilizando cal, calcário e dióxido de manganês / Study of manganese removal from mining effluent using lime, limestone and manganese dioxide
Manganese is a common component of acid mine drainage (AMD). Due to its high solubility over a wide pH range, it is notoriously difficult to remove it from contaminated waters. The AMD that occurs in Mineral Industrial Complex of Poços de Caldas (CIPC) which belongs to the Nuclear Industries of Brazil (INB), is due to the great amount of su

19. Evaluation of the impact of induction motors in electrical distribution networks and a regulation proposal to their access to low voltage networks. / Águas minerais em São Paulo.
This work as aim to draw a brief panorama of Drinking Waters that are explored in the state of São Paulo. Through this work will be studied the importance of the exploration of Drinking Waters for the São Paulo state and for the whole country. Several changes occurred in the Market of Mineral Water that in 1980 it was practically unknown. This dissertation

20. Estudo geoquímico da disposição de lodo de estação de tratamento de água em área degradada
This survey determined the physical and chemical properties of the gravel place where urban sludge from Rio Descoberto's Water Treatment Plant is disposed. Physical, chemical and biological analysis of the soil samples (n=54), sludge samples (n=2), chemical coagulant (n=20) and samples from superficial waters (n=9) and water table (n=60) were performed. As r

21. Estudo da especiação de arsênio inorgânico e determinação de arsênio total no monitoramento ambiental da qualidade de águas subterrâneas
This work reports an alternative, fast and robust method, for the determination of total As, As(III) and As(V) by HG-AAS without the use of prereductants. The method is based on the different rates of arsine formation of the inorganic As species and the effect of As(III) in the signal obtained for total As. Groundwater and mineral spiked waters were used to

23. Construction and evaluation of microsystems for flow analysis / Construção e avaliação de microssistemas para analise em fluxo
This work describes the construction, characterization and application of microsystems for flow analysis. Laser ablation was employed for the development of a system in poly(methylmethacrylate), whose channels, with rectangular cross sections measuring 200 mm width by 4,5 mm depth, were sealed with an adhesive plastic film. This device supported flow rates u

24. ECONOMIC ANALYSIS OF THE MARKET FOR MINERAL WATER / AnÃlise econÃmica do mercado de Ãgua mineral
The dissertation is proposing to submit a descriptive analysis on the market of mineral waters. The approach of the subject is done, initially, through a brief history of his downing and panoramas of the world and national market. Through the data of total volume sold per thousand liters, the total amount sold in millions of real (Brazilian money), market sh
