1. Amortecimento superficial nos sistemas de micro-drenagem em regiões de baixa declividade. / Peak flow reduction for micro-drainagem systems applied to flat areas.
O presente trabalho desenvolve uma proposta para a avaliação da redução da vazão de pico do hidrograma do método racional, no contexto de bacias hidrográficas topograficamente planas. Entendem-se como planas aquelas localidades, cujas declividades médias características e/ou projetadas são inferiores a 0,5%. Pretende-se também neste trabalho apres

2. O papel ecológico da neblina e a absorção foliar de água em três espécies lenhosas de Matas Nebulares, SP - Brasil / The ecological role of fog and foliar water uptake in three woody species from Southeastern Brazilian Cloud Forest
Fog deposition is an important water source in several terrestrial ecosystems. Fog water intercepted by the plants can run off to the soil or be absorbed by the leaves. However, very little is known about the ecological role of fog and the mechanisms and structures involved in foliar water uptake by woody species in tropical environments. In this context, we

3. MudanÃas climÃticas e impactos na demanda de Ãgua para irrigaÃÃo na Bacia do Jaguaribe / Climate change and irrigation water demand impacts on Jaguaribe basin
Climate change has a potential to impact hydrological cycle processes such as rainfall that affects run off temperature and air humidity which are related to evaporation river flow and plant evapotranspiration They may also affect water availability and crop water requirement The purpose of this research was to assess climate change impacts on irrigation wat

4. Critical rains, planning and run-off management using geografic information system on Presidente Bernardes - Cubatão Refinery (RPBC) / Precipitações criticas, planejamento e gerenciamento das drenagens superficiais utilizando sistemas de informações geograficas : Refinaria Presidente Bernardes - Cubatão (RPBC)
The increase on the rains intensity veryfied on last decades has requested the conveyances over than their capacity, showing deficiencies on old designed systems. At the same time, society has the crying need of water resources conservation, justified by the water s scarcity. In an oil refinery this subject is particularly important because of the great amou

5. Acquired aortic regurgitation following occlusion of the persistent arterial duct: an echocardiographic assessment.
OBJECTIVE: To document the development of aortic regurgitation following occlusion of a patent arterial duct. DESIGN: Case series involving nine children referred for surgical ligation of an isolated patent arterial duct. SETTING: Academic referral centre. METHODS: A preoperative transthoracic and transoesophageal echocardiogram was performed in theatre to l

6. Fluid shear stress induces endothelial transforming growth factor beta-1 transcription and production. Modulation by potassium channel blockade.
The endothelium has the capacity to modulate vascular structure in response to hemodynamic stimuli. We tested the hypothesis that exposure of the endothelium to increased laminar shear stress induces the expression of TGF beta 1 via a signal transduction pathway modulated by K+ channel currents. Although TGF beta 1 is normally secreted in a latent, inactive

7. Philanthropy and hospital financing.
OBJECTIVE. This study explores the relationships among donations to not-for-profit hospitals, the returns provided by these hospitals, and fund-raising efforts. It tests a model of hospital behavior and addresses an earlier debate regarding the supply price of donations. DATA SOURCES. The main data source is the California Office of Statewide Health Planning

8. Pathology of hearts after aortocoronary saphenous vein bypass grafting for coronary artery disease, studied by post-mortem coronary angiography.
A detailed pathological study was made in 10 patients dying up to 13 months after aortocoronary saphenous vein bypass grafting for coronary atherosclerosis. The coronary arteries and vein grafts were investigated by injection with a radio-opaque mass, radiography, dissection, and histology. The report is to some extent historical since the patients died duri
