13. Lixiviado de aterros sanitários brasileiros: estudo de remoção do nitrogênio amoniacal por processo de arraste com ar ("stripping") / Sanitary landfill leachate in Brazil: evaluation of ammonia nitrogen removal by air stripping process
Sanitary landfills are considered as the most appropriate way for final disposal of municipal solid wastes in Brazil, in the technical and economical point of view. Open dumps have been progressively substituted by well engineered and operated landfills. However, landfills still present environmental risks due to the gas emission and leachate production. Gas

14. Qualidade da água e distribuição espacial de foraminíferos bentônicos em estuários das Baías Norte e Sul da Ilha de Santa Catarina (Brasil)
Watersheds with different characteristics lead to different rates of biogeochemical elements that contribute in estuarine systems. Thus, this study investigated the contribution of drainage on the nutrients as well as the responses of benthic foraminifera, with focus on estuarine region of six major systems that discharge in the North and South bays of Santa

15. Dredging, transport and final disposition of the river bed sediments - case study: Rio Tietês Gutter - Phase II. / Dragagem, transporte e disposição final de sedimento de leito de rio - estudo de caso: Calha do Rio Tietê - Fase II.
As obras de Ampliação da Calha do Rio Tietê fazem parte de medidas estruturais que visaram ao aumento da capacidade de vazão para o controle das enchentes na RMSP. A regularidade da capacidade de vazão dependerá, dentre outras ações, de dragagens de manutenção e retirada do material dragado, cuja destinação é bastante problemática. O objetivo d

16. BARRAMENTOS NATURAIS NO VALE DO RIO PERUAÃU: CONSEQÃÃNCIAS ECOLÃGICAS E AMBIENTAIS DE EVENTOS PRETÃRITOS E FUTUROS. / Natural barring in the PeruaÃu River Valley: ecological and environmental consequences of past and future events.
Fossil assemblage found in caves record important environmental information concerning the recent past of the surrounding area. In the karstic canyon of the PeruaÃu River, Cavernas do PeruaÃu National Park, Minas Gerais - Brazil, organic deposits suggests the occurrence of major floods resulting from natural barring in the river bed.

17. Sediment yield in watersheds under different geo-environmental contexts: measured and modelling / ProduÃÃo de Sedimentos em Bacias HidrogrÃficas Sob Diferentes Contextos Geoambientais: Medida e Modelagem.
Sediment yield assessment is necessary in watersheds when it is desired to improve the quality of analysis, contributing for a consistent evaluation of water availability and, therefore, high-quality water resources management. The general objective was to evaluate the sediment yield in watersheds under different geo-environmental contexts. Three small basin

18. Neutralização de drenagem ácida de minas com escória de aciaria elétrica do forno-panela
The acid mine drainage (AMD) is formed when certain sulfide minerals are exposed to oxidizing conditions. The AMD is commonly associated with coal mining, especially in coal waste deposits that contain high pyrite (FeS2) concentration. The neutralization of AMD using alkaline materials, like limestone and steel slag is one of the useful remediation technique

19. Assessment of changes in the drainage network of hydrographic sub-basins fo the medium course of the Capivari river basin (SP): scale 1:25.000 - subsidy for integrated planning / Avaliação das alterações na rede de drenagem de sub-bacias hidrográficas da porção média da bacia do rio Capivari (SP): escala 1:25.000 - subsídio para o planejamento integrado
This work used the drainage as a geoindicator to the changes that have taken place during 23 years (1972 to 1995) in the physical environment of three hydrographic sub-basins within the Monte Mor municipal boundaries, located in the medium course of the Capivari river hydrographic basin. The methodological approach comprises a complete characterization of th

20. The blood supply of the islets of Langerhans in the Mongolian gerbil.
Ink injection studies and point counting have been used to follow and quantify the development of vascularity in the islets of Langerhans of the Mongolian gerbil. Vascularization is essentially a postnatal event in this species. Initially, islet capillaries form part of the general capillary bed of the gland, but subsequently they develop a direct arteriolar

21. Adhesive Tape: Potential Source of Nosocomial Bacteria
During a 7-day period, a variety of bacteria, including opportunistic ones, were recovered from 23 rolls of adhesive tape being used in a 16-bed intensive care unit. All rolls of tape were sterile when received from the manufacturer. Mixed flora was recovered from a total of 15 rolls, whereas eight rolls yielded pure cultures. Organisms recovered included St

22. Atypical cotton-wool spots.
Atypical cotton-wool spots in four selected cases of diabetic retinopathy are discussed. The most striking characteristic distinguishing them from typical cotton-wool spots is their size, which ranges from about 2 to 4 disc diameters. They develop after stenosis or a complete obstruction of a first order arteriole at the point at which it emerges from the pa

23. The nursing position after operation and the work of breathing
Patients after operation are often nursed with the foot of the bed raised in order to facilitate drainage of blood from the legs and of secretions from the trachea. Measurements of the changes in lung volume, of the oxygen cost of breathing, and of the movements of the rib cage and abdomen in the sitting, supine, and 15 degree head-down positions have been m

24. Denervated splenopancreatic flap for chronic pancreatitis.
Various surgical procedures have addressed the disabling pain of chronic pancreatitis. Pain control must be weighed against the surgical morbidity and metabolic consequences of operation. Although ductal drainage works well for patients with dilated ducts, a new procedure was devised to avoid the diabetic morbidity of near-total pancreatectomy or pancreatico
