1. Effects of miniemulsion operation conditions on the immobilization of BSA onto PMMA nanoparticles
Abstract Polymer nanoparticles have been widely used in many biomedical applications, constituting a major incentive for immobilization of proteins. Poly(methyl methacrylate) nanoparticles were synthesized through miniemulsion polymerizations and used as supports for bovine serum albumin immobilization. Particularly, the effects of surfactant type (anionic s

2. Population Changes of Eubacteria, Sulfate-Reducing Bacteria and Methanogenic Archaea in an Anaerobic Reactor Processing Ethanol Distillery Vinasse
Abstract The microbiological characterization by molecular techniques (DGGE and quantitative PCR) of Archaea, Bacteria domain and sulfate-reducing bacteria (SRB) from a laboratory scale Up-flow Anaerobic Sludge Blanket (UASB) processing sugar cane vinasse was performed during the operational phase with increasing organic loads. The organic load removal effic

3. Síntese e caracterização de nanocompósitos de poliestireno/hidroxissal lamelar
Polystyrene/layered hydroxide salt (LHS) modified with sodium dodecyl sulfate was synthesized by in situ polymerization. The materials synthesized were characterized by gravimetry, X-ray diffraction (XRD), thermogravimetry analyses (TGA), differential scanning calorimetry (DSC) and the flammability test (FT). XRD demonstrated that synthesized nanocomposites

4. The effect of acute magnesium loading on the maximal exercise performance of stable chronic obstructive pulmonary disease patients
OBJECTIVE: The potential influence of magnesium on exercise performance is a subject of increasing interest. Magnesium has been shown to have bronchodilatatory properties in asthma and chronic obstructive pulmonary disease patients. The aim of this study was to investigate the effects of acute magnesium IV loading on the aerobic exercise performance of stabl

5. Aplicação de reatores anaeróbios para remoção de sulfato de águas de drenagem ácida de minas / Sem título traduzido.
O presente trabalho teve, por objetivo principal, analisar a remoção de sulfato em águas de drenagem ácida de minas em dois tipos de reatores anaeróbios, um com crescimento granular (UASB) e outro com biomassa aderida (RAHLF). Estudos anteriores publicados na literatura apresentam resultados positivos quanto ao tratamento anaeróbio de drenagem ácida d

6. Efeito da adição de carga e extensor nas propriedades do adesivo uréia-formaldeído e dos compensados de pinus e paricá / Effect of the addition of filler and extender on urea- formaldehyde adhesives and on pinus and paricá plywood properties
The objective of this study was to evaluate the effect of the addition of extender (wheat flour) and filler (babaçu flour) on urea-formaldehyde adhesive properties and on quality of plywood manufactured with Pinus elliottii e Schizolobium amazonicum (paricá) veneers. Ninety six three-layer plywood were produced, being forty eight produced with Pinus elliot

7. Variação da qualidade da água do escoamento superficial de duas bacias de drenagem de Natal/RN - Brasil
The urban drainage is one of the powers of environmental sanitation and its scope is the quantitative and qualitative aspects. In decision making of managers and the engineering aspects of design are almost always taken into account only the quantitative aspects. However, the waters of the runoff have the highest concentrations of pollutants at the beginning

8. Bioquimica e biomecanica dos tendões flexores digitais de frangos
Tendons have function of transmitting tension forces from musc1e to bones. The tendinous connective tissue changes their mechanical and structure properties in response to stress alteration as a phenomenon of functional adaptation and optimal operation. The peculiar characteristic of connective tissue is the presence of collagen in the extracellular matrix,

10. Enhanced Reduction of Helicobacter pylori Load in Precolonized Mice Treated with Combined Famotidine and Urease-Binding Polysaccharides
The present study investigated the effect of a model urease-binding polysaccharide in combination with a histamine H2 receptor antagonist on Helicobacter pylori colonization in vivo. Euthymic hairless mice were treated daily with dextran sulfate via drinking water and/or famotidine via intragastric gavage starting at 1 week postchallenge with a CagA+ VacA+ (

11. Removal of methanethiol, dimethyl sulfide, dimethyl disulfide, and hydrogen sulfide from contaminated air by Thiobacillus thioparus TK-m.
Methanethiol, dimethyl sulfide, dimethyl disulfide, and hydrogen sulfide were efficiently removed from contaminated air by Thiobacillus thioparus TK-m and oxidized to sulfate stoichiometrically. More than 99.99% of dimethyl sulfide was removed when the load was less than 4.0 g of dimethyl sulfide per g (dry cell weight) per day.

12. An in vivo microperfusion study of distal tubule bicarbonate reabsorption in normal and ammonium chloride rats.
For many years it has been thought that distal nephron hydrogen ion secretion can be importantly modulated by factors such as sodium delivery, sodium avidity, and potassium stores. Free flow micropuncture studies have also indicated that the rate of bicarbonate delivery may also alter the rate of bicarbonate reabsorption. The present studies were undertaken
