13. Produção de forragem verde em sistema hidropônico usando esgoto tratado
In the urban areas of the cities a larger problem of destiny of effluents of the treatment stations is verified due to the junction of the sewages in great volumes. This way the hidroponic cultive becomes important, for your intensive characteristic, as alternative of reuse. This work presents as objective the improvement of the relation hidric-nutritious of

14. Modeling heat and mass transfer in the heat treatment step of yerba maté processing
The aim of this research was to estimate the leaf and twig temperature and moisture content of yerba maté branches (Ilex paraguariensis Saint Hilaire) during heat treatment, carried out in a rotary kiln dryer. These variables had to be estimated (modeling the heat and mass transfer) due to the difficulty of experimental measurement in the dryer. For modelin

16. THE PORT OF SALVADOR: ANALYSIS OF THE CURRENT REALITY, ITS NECESSITIES AND COMPARISONS AFTER LAW 8.630/93 / O PORTO DE SALVADOR: ANÁLISE DA REALIDADE ATUAL, SUAS NECESSIDADES E COMPARAÇÕES PÓS LEI 8.630/93
The follow document has the main objective to make a complete analysis of the current port situation of the main port of the Brazilian northeast region, since the implementation of the law 8.630 dated of February, 25th, 1993, known as the law of modernization of the ports, until the current days. It makes a analysis of the port, the law 8.630 and of the publ

17. APERFEIÇOAMENTO E APLICAÇÕES DE UMA METODOLOGIA PARA ANÁLISE DE ESPECIAÇÃO DE ARSÊNIO POR ELETROFORESE CAPILAR COM DETECTOR DE ICPMS / IMPROVEMENTS AND APPLICATIONS OF A METHODOLOGY FOR THE SPECIATION ANALYSIS OF ARSENIC USING CAPILLARY ELECTROPHORESIS WITH ICPMS DETECTOR
Capillary electrophoresis (CE) is a well established separation technique for the study of elemental speciation, however, its low electroosmotic flow nL min(-1) restricts its application in many studies in which low detection limits are required. For this reason, the study of CE coupling (hyphenation) to more sensitive detectors is of great relevance. This w

18. Comparative study of the performance of patients with Alzheimer´s disease and vascular dementia in neuropsychological tests / "Estudo comparativo do desempenho em testes neuropsicológicos de pacientes com diagnóstico de doença de Alzheimer e demência vascular"
A doença de Alzheimer (DA) e a demência vascular (DV), especialmente a sua forma subcortical, são responsáveis pela maioria dos quadros de demência em idosos, nem sempre facilmente diferenciadas do ponto de vista clínico. O objetivo do estudo foi comparar o desempenho de pacientes com DA e com DV em uma bateria breve de testes cognitivos (Mini-exame do

19. Análise da fluidodinâmica de calor em leito de jorro com alimentação contínua de sólidos pela base.
The objective of this work was to develop a theoretical and experimental study of fluid dynamics and heat transfer in a spouted bed with draft tube, which operates in continuous mode with particles feed through the bottom of the bed. This arrangement was chosen in order to maintain axial symmetry inside the bed. The chosen model was a steady-state model with

20. Estudo experimental do secador pneumatico vertical
This work is related with studies on the performance of a vertical pneumatic dryer on a well instrumented pilot plant. Experiences were rea1ized with sand particles with a mean diameter of 0.46mm and 0.55mm and glass spheres with a mean diameter of 0.24mm, in a drying tube with 4m high and an inside diameter of 5.25cm, aiming the determination of the air hum

21. Glutamate Transport in Escherichia coli K-12: Nonidentity of Carriers Mediating Entry and Exit
The exit of glutamate from Escherichia coli K-12 cells preloaded with the radioactive amino acid and its relation to the reaction of entry were studied. Experiments with cells preloaded to different intracellular concentrations of radioactive glutamate confirmed our earlier conclusion that glutamate exit was a first-order reaction. l-Glutamate, competitive i

22. Fission yeast Clp1p phosphatase affects G2/M transition and mitotic exit through Cdc25p inactivation
The Cdc14 family of phosphatases specifically reverses proline-directed phosphorylation events. In Saccharomyces cerevisiae, Cdc14p promotes Cdk1p inactivation at mitotic exit by reversing Cdk1p-dependent phosphorylations. Cdk1p is a proline-directed kinase whose activity is required in all eukaryotes for the transit into mitosis. At mitotic commitment, Cdk1

23. Modeling the fission yeast cell cycle: Quantized cycle times in wee1− cdc25Δ mutant cells
A detailed mathematical model for the fission yeast mitotic cycle is developed based on positive and negative feedback loops by which Cdc13/Cdc2 kinase activates and inactivates itself. Positive feedbacks are created by Cdc13/Cdc2-dependent phosphorylation of specific substrates: inactivating its negative regulators (Rum1, Ste9 and Wee1/Mik1) and activating

24. Dual mode of degradation of Cdc25 A phosphatase
The Cdc25 dual-specificity phosphatases control progression through the eukaryotic cell division cycle by activating cyclin-dependent kinases. Cdc25 A regulates entry into S-phase by dephosphorylating Cdk2, it cooperates with activated oncogenes in inducing transformation and is overexpressed in several human tumors. DNA damage or DNA replication blocks ind
