1. SYNTHESIS, CHARACTERIZATION, ADSORPTION AND THERMODYNAMIC STUDIES OF PURE AND BINARY CO2-N2 MIXTURES ON OXYGEN ENRICHED NANOSTRUCTURED CARBON ADSORBENTS
Abstract Oxygen enriched porous carbons have been synthesized by a nanocasting technique using mesoporous zeolite as template and epoxy resin as precursor. Characterization results show the effect of the nanocasting technique on the development of heterogeneous surface, high basicity, and high surface area of 686.37 m2g-1, beneficial for CO2 adsorption. Pure

2. Flexure Based Energy Dissipating Device in Self-Centering Braces
Abstract Self-centering braces, in the current stage of development can accommodate large deformation and force levels. However, there is still a need for improvement of the energy dissipation mechanisms commonly incorporated in these braces. Yield based energy dissipation systems can overcome some of the problems faced with friction-based devices, such as s

3. AVALIAÇÃO DO PERFIL DE LIBERAÇÃO DO FÁRMACO IBUPROFENO EM MEMBRANAS SIMÉTRICAS E ASSIMÉTRICAS DE ACETATO DE CELULOSE: EFEITO DA MORFOLOGIA
Cellulose derivatives still receive special attention in today biomedical applications due to their biocompatibility, ability to form resistant membranes and compatibility with various bioactive agents. In this work, cellulose acetate (CA) was used to prepare membranes with different morphologies aiming to evaluate the release profile of the drug ibuprofen (

4. O Efeito da Assimetria de Informação Entre o Regulador e os Bancos no Requerimento de Capital Para Risco Operacional
Resumo Em meio às discussões sobre o novo modelo padronizado (SMA) para requerimento de capital para risco operacional e a possível extinção dos modelos internos (AMA), este estudo analisa os efeitos da assimetria de informação (forte característica do risco operacional) nas interações entre o regulador e o banco quanto à adoção de modelos inter

6. Analysis of the global second-order effects on irregular reinforced concrete structures using the natural period of vibration
Resumo O parâmetro χT, recentemente apresentado na literatura técnica, permite utilizar o período natural de vibração da estrutura para estimar os efeitos globais de segunda ordem em pórticos de concreto armado. Esse parâmetro foi desenvolvido a partir da observação de que os efeitos de segunda ordem e o período natural de vibração dependem esse

7. Demographic, clinical and lifestyle predictors for severity of erectile dysfunction and biomarkers level in Malaysian patients
The incidence of erectile dysfunction (ED) is rising worldwide and its prevalence is one of the main health concerns that affect overall men well-being in Malaysia. The cluster of demographic, clinical and lifestyle factors may have contributed to the severity of ED and changes in biomarkers level; nevertheless these have not been studied extensively. This c

8. Asymmetric bioreduction of β-ketoesters derivatives by Kluyveromyces marxianus: influence of molecular structure on the conversion and enantiomeric excess
ABSTRACT This study presents the bioreduction of six β-ketoesters by whole cells of Kluyveromyces marxianus and molecular investigation of a series of 13 β-ketoesters by hologram quantitative structure-activity relationship (HQSAR) in order to relate with conversion and enantiomeric excess of β-stereogenic-hydroxyesters obtained by the same methodology.

9. Valuing flexibility in electro-intensive industries: the case of an aluminum smelter
Abstract Electro-intensive industries account for a significant proportion of the total industrial electricity consumption, and these industries usually possess co-generation assets, which can supply at least part of their energy needs. However, due to price uncertainty, it may be optimal for the firm to temporarily suspend production and sell the available

10. Fluctuating asymmetry of and herbivory on Poincianella pyramidalis (Tul.) L.P. Queiroz (Fabaceae) in pasture and secondary tropical dry forest
Plants subjected to stressful environments tend to be more asymmetric with reduced defenses and are therefore more vulnerable to herbivory. This study investigates the relationship between herbivory and fluctuating asymmetry (FA) in Poincianella pyramidalis in two contrasting habitat types in the Brazilian caatinga (shrublands). We tested the following hypot

11. Simulação de um alimentador Venturi em trecho ascendente no transporte pneumático de sólidos
The radial and axial distributions of coarse solids when fed directly in a riser are unknown, despite this type of feeding is very important for drying and preheating of solids during conveying. In this context, this thesis focused on studying the diluted conveying of coarse solids in a riser that was fed by a Venturi feeder in vertical orientation. Experime

12. Evaluation of microbiological and biomimetic models in stereoselective metabolism of risperidone by high-performance liquid chromatography / Avaliação de modelos microbiológicos e modelos biomiméticos no metabolismo estereosseletivo da risperidona por cromatografia líquida de alta eficiência
Risperidone is an atypical antipsychotic drug. Its metabolism yields in two hydroxylated chiral metabolites, 7-hydroxyrisperidone (7-RispOH) and 9-hydroxyrisperidone (9-RispOH). The 9-RispOH metabolite presents the same pharmacologic activity of the parent drug risperidone. This led this drug to be marketed as drug under the generic name paliperidone. Studie
