1. Avaliação de impactos da cadeia produtiva em aeroportos : o caso de Congonhas
Over time, the business grossed airport beyond its traditional functions, such as transporting passengers and cargo, commercial functions, with the inclusion of shopping malls, cinemas, food courts, among others. Thus, several developments aids such as logistics companies, car rental, travel agencies and even residential neighborhoods, occupied in a disorder

2. EXPERIMENTAL EVALUATION OF TRANSPORT PARAMETERS IN SHALES / AVALIAÇÃO EXPERIMENTAL DOS PARÂMETROS DE TRANSPORTE EM FOLHELHOS
The majority of the problems related to wellbore stability occur when argillaceous rocks, such as shales, are drilled. Such problems are believed, in general, to be caused by the physical-chemical interaction between drilling fluids and the referred rocks. This dissertation focuses on the experimental study of the behavior of shales exposed to different sali

3. Simulação numérica da separação de misturas CH4/He e CO2/He em colunas de adsorção em leito fixo
Methane and carbon dioxide gases are part of natural gas composition and methane is in bigger proportion. Both gases are pollutants which methane is the most responsible by the greenhouse effect and carbon dioxide in turn by pipelines oxidation in natural gas transporting. The separation of CO2 from natural gas promotes an increase in calorific power of the

4. DETERMINAÇÃO DE ELEMENTOS MENORES E TRAÇO EM ROCHAS POR LA-ICPMS: PROGRESSOS NA UTILIZAÇÃO DE VIDROS BORATOS COMO ALVOS / DETERMINATION OF MINOR AND TRACE ELEMENTS IN ROCK SAMPLES BY LA-ICPMS: PROGRESS IN THE UTILIZATION OF BORATE GLASSES AS TARGETS
The present master dissertation is a continuation of a research study developed by Leite (2006) aiming at the multielemental analysis of rock samples (basalts, obsidians and shale) by inductively coupled plasma mass spectrometry (ICPMS), in combination with laser ablation (LA) and using borate glass as analytical targets. As in the former work, the experimen

5. Análise crítica do ensaio NACE TM-0172 para verificação da agressividade de derivados de petróleo. / Critical analysis of the NACE TM-0172 test to verify the corrosive properties of distillate fuels.
Before transporting distillate fuels by pipelines, their corrosive properties are verified by the NACE TM-0172 test ?Determining Corrosive Properties of Cargoes in Petroleum Product Pipelines? (NACE, 2001). This test, being based on a visual evaluation, has as its goal, neither the determination of the corrosion rate nor the verification of the corrosion typ

6. Investigation of the Calcium-Transporting ATPases at the Endoplasmic Reticulum and Plasma Membrane of Red Beet (Beta vulgaris).
Calcium-transporting ATPases were compared in endoplasmic reticulum (ER)- and plasma membrane-enriched fractions of red beet (Beta vulgaris L.) storage tissue by measuring 45Ca uptake and calcium-dependent phosphoenzyme formation. The plasma membrane fraction was prepared by aqueous two-phase partitioning of a microsomal fraction and collecting the upper pha

7. Expression cloning of a rat liver Na(+)-independent organic anion transporter.
Using expression cloning in Xenopus laevis oocytes, we have isolated a cDNA encoding a rat liver organic anion-transporting polypeptide (oatp). The cloned oatp mediated Na(+)-independent uptake of sulfobromophthalein (BSP) which was Cl(-)-dependent in the presence of bovine serum albumin (BSA) at low BSP concentrations (e.g., 2 microM). Addition of increasin

8. Characterization of a gene encoding a Ca(2+)-ATPase-like protein in the plastid envelope.
By screening an Arabidopsis expression library with an antiserum against chloroplast envelope proteins, we have isolated a partial cDNA with an open reading frame that encodes a polypeptide similar to P-type cation-transporting ATPases. The corresponding genomic clone was isolated and the complete coding sequence was deduced after identification and mapping

9. Immunolocalization of the mercurial-insensitive water channel and glycerol intrinsic protein in epithelial cell plasma membranes.
Two water channel homologs were cloned recently from rat kidney, mercurial-insensitive water channel (MIWC) and glycerol intrinsic protein (GLIP). Polyclonal antibodies were raised against synthetic C-terminal peptides and purified by affinity chromatography. MIWC and GLIP antibodies recognized proteins in rat kidney with an apparent molecular mass of 30 and

10. Continuous amperometric monitoring of glucose in a brittle diabetic chimpanzee with a miniature subcutaneous electrode
The performance of an amperometric biosensor, consisting of a subcutaneously implanted miniature (0.29 mm diameter, 5 × 10−4 cm2 mass transporting area), 90 s 10–90% rise/decay time glucose electrode, and an on-the-skin electrocardiogram Ag/AgCl electrode was tested in an unconstrained, naturally diabetic, brittle, type I, insulin-dependent chimpanzee.

11. Rod phototransduction modulated by bicarbonate in the frog retina: roles of carbonic anhydrase and bicarbonate exchange.
1. Effects on rod phototransduction following manipulation of retinal CO2-HCO3- and H+ fluxes were studied in dark-adapted retinas of the frog and the tiger salamander. 2. Rod photoresponses to brief flashes of light were recorded from the isolated sensory retina as electroretinogram mass receptor potentials and from isolated rods by the suction-pipette tech
