ARSENIC IN TROPICAL SURFACE ENVIRONMENTS Geochemical processes that govern weathering conditions of auriferous deposits in the Iron Quadrangle, Minas Gerais, Brazil were studied through X-Ray Diffraction analysis, Scanning Electronic Microscopy, and chemical analysis of groundwater collected in mines. Natural oxidation of arsenopyrite in quartz-arsenopyrite veins (without carbonates) promotes the formation of scorodite, while the oxidation of arsenopyrite in veins of…

to think about the EU in terms of treaties and enlargements. The first treaty within the Union was the Treaty of Rome in 1957. In fact, there was a prior treaty which isn’t considered, the Treaty of Paris: Treaty of Paris & Treaty of Rome – 1950’s: Coal and Steel, this community was the 1st and has lasted for 50 years, next came EURATOM (to study atomic energy) and the EEC (European Economic Community). In Paris we dealt with one community (Coal and Steel), and in the Treaty of…

by different kinds of anthropogenic activities. The exposure to two or more chemicals may result in biological reponses quantitatively or qualitatively different from that expected from the action of the chemicals alone (Rand et al., 1995). In Brazil, as in other developing countries, criteria for the classification of water courses are exclusively based on physical and chemical factors (CONAMA, 1992) and chemical analyses are normally restricted to identification of a limited range…

independent) to quantify the stress or strain at a point. For this case, the variable is normally expressed in a matrix format with three rows and three columns. To summarize this discussion, in a three-dimensional Cartesian coordinate system, scalar, vector, and matrix variables can thus be written as follows: 3 mass density scalar ¼ r displacement vector ¼ u ¼ ue1 þ ve2 þ we3 2 3 sx txy txz 6 7 stress matrix ¼ [s] ¼ 4 tyx sy tyz 5 tzx tzy sz where e1 , e2 , e3 are…

heat transfer coefficient of a circular, hot gas jet at T∞ directed normal to a circular plate at Ts of radius ro. FIND: Heat transfer rate to the plate by convection. SCHEMATIC: ASSUMPTIONS: (1) Steady-state conditions, (2) Flow is axisymmetric about the plate, (3) For h(r), a and b are constants and n ≠ -2. ANALYSIS: The convective heat transfer rate to the plate follows from Newton’s law of cooling q conv = ∫ dq conv = ∫ h ( r ) ⋅ dA ⋅ ( T∞ − Ts ). A A The local heat transfer…
