2. OWNERSHIP STRUCTURE AND INTERNATIONALIZATION: AGENCY PROBLEMS AND DELISTING IN BRAZIL
ABSTRACT Purpose: This study aimed to analyze determinants related with the delisting of Brazilian companies, through the analysis of the problems of agencies coming from structures of property/control and the internationalization of organizations. Originality/value: The present work seeks to fill the existing gap of more detailed studies related to the de

3. A quantitative relationship between Tgs and chain segment structures of polystyrenes
Abstract The glass transition temperature (Tg) is a fundamental characteristic of an amorphous polymer. A quantitative structure-property relationship (QSPR) based on error back-propagation artificial neural network (ANN) was constructed to predict Tgs of 107 polystyrenes. Stepwise multiple linear regression (MLR) analysis was adopted to select an optimal su

4. An Active Search Method for Finding Objects with Near-Optimal Property Values within a Given Set
This paper proposes an active search method aimed at finding objects with optimal or near-optimal y-property values, on the basis of x-variables obtained by indirect, less costly methods. The proposed method progresses in a sequential manner, starting from a small subset of objects with known y-values. At each iteration, the K-nearest neighbour regression te

5. PREDICTING THE BOILING POINT OF PCDD/Fs BY THE QSPR METHOD BASED ON THE MOLECULAR DISTANCE-EDGE VECTOR INDEX
The quantitative structure property relationship (QSPR) for the boiling point (Tb) of polychlorinated dibenzo-p-dioxins and polychlorinated dibenzofurans (PCDD/Fs) was investigated. The molecular distance-edge vector (MDEV) index was used as the structural descriptor. The quantitative relationship between the MDEV index and Tb was modeled by using multivaria

6. Hot corrosion behavior of monel 400 and AISI 304 dissimilar weldments exposed in the molten salt environment containing Na2SO4 + 60% V2O5 at 600 °C
This research work investigates the use of pulsed current for joining two dissimilar metals Monel 400 and AISI 304 using Pulsed Current Gas Tungsten Arc welding using three different filler metals such as ER309L, ERNiCu-7 and ERNiCrFe-3. Microstructure observations showed the presence of Partially Melted Zone (PMZ) at the heat affected zone (HAZ) of all the

7. Interactions of chitosan/genipin hydrogels during drug delivery: a QSPR approach
A hydrogel comprised of chitosan crosslinked using the low-toxicity crosslinker genipin was prepared, and the absorption of glibenclamide by the hydrogel was investigated. Optimized structures and their molecular electrostatic potentials were calculated using the AM1 method, and the results were used to evaluate the molecular interactions between the three c

8. Planejamento de inibidores baseado em fragmentos moleculares para a enzima gliceraldeído-3-fosfato desidrogenase de Trypanosoma cruzi / Design of inhibitors through fragment-based drug discovery for the enzyme glyceraldehyde-3-phosphate dehydrogenase from Trypanosoma cruzi
Chagas disease is a parasitic illness endemic in Latin America caused by the trypanosomatid parasite Trypanosoma cruzi that spreads around the world due to people migration. Nowadays, Benznidazole and Nifurtimox (banned in Brazil), are used for the treatment of this disease but causes severe side effects to patients. Recently, three new molecules have reache

9. Relação entre a estrutura molecular e as propriedades de absorção de multi-fótons em compostos orgânicos π-conjugados / Structure-property relationship for multiphoton absorption process in π-conjugated organic compounds
Nesta tese estudamos a relação entre as propriedades de absorção de multi-fótons e a estrutura molecular de três classes distintas de compostos orgânicos π-conjugados: derivados de vitamina A, complexos de platina acetilada e compostos quirais. Materiais orgânicos emergiram nas últimas décadas como candidatos para aplicações em dispositivos fo

10. Química supramolecular de fármacos antirretrovirais inibidores nucleosídeos de transcriptase reversa: novas formas cristalinas e alteração de propriedades de estado sólido / Supramolecular chemistry of antiretroviral nucleoside reverse transcriptase inhibitor drugs
Solid state properties are directly related to drug performance. Among all physical and chemical properties dependent on the crystal phase of a drug, stability and solubility are the main ones that alter its bioavailability. In this way, molecular crystal engineering is a strategy to improve solid state properties of drugs related to their efficacies. In thi

11. A desigualdade social no nordeste metropolitano : análise do período 1981 a 2008 / The inequality in Northeast metropolitan : analysis of the period 1981 to 2008
This paper analyzes the evolution, between 1981 and 2008, of social inequality in metropolitan areas of Salvador, Recife and Fortaleza. First of all, the main structural causes of social inequality in Brazil are discussed: the land property concentration, the structure of labor market, social policies and regional question. The national overview supports the

12. Structure, morphology and magnetism of an ultra-thin [NiO/CoO]/PtCo bilayer with perpendicular exchange bias
Electronic and magnetic properties of nanoscale materials are closely related to the atomic arrangement at the interface shared by different chemical elements. A very precise knowledge of the surface/interface structure is then essential to properly interpret the new properties coming out. Of a particular interest is the relationship between structure, morph
