1. Evaluation methods of management of residues in building sites OS civil construction: proposal bassed on building companies of the city of Natal/RN / Método de avaliação do gerenciamento de resíduos em canteiro de obras da construção civil : proposta baseada em empresas construtoras da cidade de Natal-RN
According to great concern between the developed industrial activities and resultant impacts over the environment, an association of several factors have occurred, procedures to the efficient management of the rotation between economical development and the environment have been improved. A research in field have been realized inside building sites of compan

2. 66Ga como padrão de calibração de raios de altas energias para detectores HPGe / Ga66 as a standard for high energy gamma rays
This work involves the study of the peak efficiency and response function of HPGe detectors for gamma rays in the energy range of 2 to 5 MeV, somewhat above the energy range of the available calibration sources for gamma spectroscopy. It is part of a high energy (up to 20MeV) -ray project to obtain intensity of rays from photo nuclear reactions produced with

3. Aspects of the time-space variation of the phytoplankton biomass and production and related parameters in Santos Estuary and Bay / Aspectos da variação espacial e temporal da biomassa e produção fitoplanctônica e parâmetros correlatos no estuário e baía de Santos
The relationship between time-space variations of phytoplankton biomass and primary productivity and the variability in physical and chemical characteristics of the water column was investigated by monthly samplings of temperature, salinity, inorganic nutrients, seston and phytoplankton biomass in 4 oceanographic stations in Santos Bay and 3 stations in Sant

4. AplicaÃÃo de um modelo paramÃtrico para a estimativa do transporte de sedimentos arenosos na Bacia de Campos / Application of a parametric model to assess the sandy sediment transport in the Campos Basin
Studies about sediment transport processes that occur in the Campos Basin are of great importance, since they can contribute for example to improve the comprehension of how the sedimentary deposits, that are potential oil reservoirs, take form or to provide elements that can help to understand the changes in marine bed forms on areas where submarine pipeline

5. ESTUDOS GENÉTICOS SOBRE A VIRULÊNCIA DE Escherichia coli ENTEROAGREGATIVA ATÍPICA / Genetic studies on the virulence of atypical enteroaggregative Escherichia coli.
Escherichia coli enteroaggregative (EAEC) is emerging as a significant diarrheal pathogen. EAEC is defined by its characteristic stacked brick aggregative adherence (AA) pattern of adherence to HEp-2 cells. Most EAEC strains harbor a 60 to 65-MDa virulence plasmid (pAA). A 1-Kb fragment of pAA, referred to as the AA probe or CVD432, has been widely used for

6. VOLTAGE STABILITY REINFORCEMENT ON ELETRIC POWER SYSTEMS / REFORÇO DAS CONDIÇÕES DE ESTABILIDADE DE TENSÃO NA OPERAÇÃO DO SISTEMA ELÉTRICO
As the electric power transmission networks became more interconnected, the thermal limits of lines and transformers restrict less the power transmission. Similarly, the use of static systems of reactive power compensation increases the power transmission capacity in systems whereas before they were limited by problems of angular stability. Actually, transmi

7. ANÁLISE DE DESEMPENHO DA TÉCNICA DE MULTIGRID EM PROBLEMAS DE FENÔMENOS DE TRANSPORTE / ANÁLISIS DEL DESEMPEÑO DE LA TÉCNICA MULTIGRID EN PROBLEMAS DE FENÓMENOS DE TRANSPORTE / PERFORMANCE ANALYSIS OF THE MULTIGRID TECHNIQUE FOR TRANSPORT PHENOMENA PROBLEMS
The numerical solution of fluid flows problems with heat transfer requires the solution of a set of coupled non- linear partial differencial equations. The major computational effort in solving these equations is due to the solution of the algebraic systems resultant from the discretization of the conservation equations. The convergence rate of iterative met

8. Transpiration, a prerequisite for long-distance transport of minerals in plants?
The major “benefit” alleged to accrue from transpiration (the evaporative loss of water from plant surfaces) is that it is essential for the long-distance transport of mineral ions, but the possible interrelation between these two processes has rarely been tested. Transpiration was experimentally dissociated from mineral supply by growing sunflowers (Hel

9. NMR studies of 5-hydroxytryptamine transport through large unilamellar vesicle membranes.
Nuclear magnetic resonance techniques developed to study membrane permeability in closed membrane systems have been used to investigate transport of 5-hydroxytryptamine across the phospholipid membranes of large unilamellar vesicles. The vesicles, modeling the 5-hydroxytryptamine storage organelles of blood platelets, contained a high internal level of ATP b

10. Transgenic mouse models of lipoprotein metabolism and atherosclerosis.
Lipoprotein transport genes have either been added to the germ line of mice by transgenic techniques or knocked out by homologous recombination in embryonic stem cells. The resultant over- or underexpression of these genes has resulted in new insights about how these genes function in the body and their role in lipoprotein metabolism. Either singly or in com

11. Structural and functional analysis of cloned DNA containing genes responsible for branched-chain amino acid transport in Escherichia coli.
The four genes encoding the components of the high-affinity branched-chain amino acid transport systems in Escherichia coli (livH, livG, livJ, and livK) have been cloned into lambda phage and subsequently into the plasmid vector pACYC184. The presence of the four structural genes and their accompanying regulatory regions on the resultant plasmid, pOXI, was c

12. Detergent-enabled transport of proteins and nucleic acids through hydrophobic solvents.
It is demonstrated that proteins and nucleic acids can be transported through hydrophobic organic solvents (liquid membranes) via nonspecific complex formation with detergents, whereas no macromolecule transport is observed without the latter. A protein (or a nucleic acid) first interacts with an oppositely charged detergent due to hydrophobic ion pairing in
