13. INVESTIGAÇÃO DA SUPRESSÃO DE FLUORESCÊNCIA DE SORO ALBUMINA BOVINA E HUMANA POR COMPLEXO DE RUTÊNIO
The binding of [RuCl2(L)] (L = N,N-bis(7-methyl-2-pyridylmethylene)-1,3-diiminopropane) to bovine and human serum albumin was investigated by the fluorescence quenching technique. The comparison of the quenching effect of serum albumin fluorescence by ruthenium complex allowed the estimation of subdomain IB in BSA and subdomain IIA in HSA as the binding site

14. One hundred cases of sui treatment that failed: a prospective observational study on the behavior of patients after surgical failure
Objectives Determine what happens to patients after unsuccessful SUI operations and to explore the reasons why these patients change doctors. Materials and Methods One hundred consecutive failed patients treated for SUI were interviewed about the exams requested after persistence of the incontinence as well as the reasons they abandoned their primary do

15. Gap Dependent Bifurcation Behavior of a Nano-Beam Subjected to a Nonlinear Electrostatic Pressure
This paper presents a study on the gap dependent bifurcation behavior of an electro statically-actuated nano-beam. The sizedependent behavior of the beam was taken into account by applying the couple stress theory. Two small and large gap distance regimes have been considered in which the intermolecular vdW and Casimir forces are dominant, respectively. It h

16. Short-term stability of estuarine benthic assemblages: are storms pattern-defining events?
Storms, associated with strong winds and heavy rains, are often the most severe physical disturbances in shallow coastal areas causing instability to sedimentary environments. We hypothesized herein that if storms influence short-term assemblage structure of macrofauna, then assemblages should change after storms, while remaining relatively stable over calm

17. Temporal variation in the composition of ant assemblages (Hymenoptera, Formicidae) on trees in the Pantanal floodplain, Mato Grosso do Sul, Brazil
Temporal variation in the composition of ant assemblages (Hymenoptera, Formicidae) on trees in the Pantanal floodplain, Mato Grosso do Sul, Brazil. In this paper we investigate how seasonal flooding influences the composition of assemblages of ants foraging on trees in the Pantanal of Mato Grosso do Sul. During the flood in the Pantanal, a large area is cove

18. Jornal Correio Paulistano - constituição e mudança do gênero anúncio de emprego (1854 a 1900) sob a perspectiva crítico-discursiva / Newspaper Correio Paulistano - Constitution and change in Job Advertisements genre (from 1854 to 1900) under a critical-discursive perspective
The aim of this thesis is to present a diachronic analysis of the speech genre job advertisements published in the newspaper Correio Paulistano from 1854 to 1900. Based on the perspective of Mikhail Bakhtin, we will emphasize their constitutive aspects and their relative stability, because speech genres are the product of a dialogic tension between two force

19. NANOCOLORAÇÃO DE LIGAS DE ALUMÍNIO / NANOCOLORING OF ALUMINUM ALLOYS
The use of aluminum becomes increasing because of the lightness of this metal and its high corrosion resistance. The anodization of the aluminum is now a well known and is widely used to increase the durability of the metal. This electrochemical technique forces the growth of oxide layer. The anodized layer has the peculiarity of having the nanotubes which a

20. A procedure for the parametric identification of viscoelastic dampers accounting for preload
Passive vibration isolators are usually made of viscoelastic materials. These materials have non-linear characteristics that change their dynamical properties with temperature, frequency and strain level. The vibration isolator's mathematical modeling and optimal design require the prior knowledge of the stiffness and damping of the applied viscoelastic mate

21. Wear of double crown systems: electroplated vs. casted female part
OBJECTIVES: The wear of telescopic crowns is a common problem often reducing the patient's satisfaction with the denture and resulting in a renewal of the denture. The study aims to compare the wear behavior of conical crowns using electroplated copings (group E ) with standard telescopic crowns with cast female parts (group C). MATERIAL AND METHODS: 10 coni

22. Cementum, apical morphology and hypercementosis: a probable adaptive response of the periodontal support tissues and potential orthodontic implications
Information about orthodontic movement of teeth with hypercementosis is scarce. As cementum deposition continues to occur, cementum is expected to change the shape of the root and apex over time, but this has not yet been demonstrated. Nor has it ever been established whether it increases or decreases the prevalence of root resorption during orthodontic trea

23. Os determinantes das fusões e aquisições no varejo de móveis e eletrodomésticos do Brasil (2004-2010).
O presente trabalho tem como principal objetivo identificar os determinantes das fusões e aquisições ocorridas no varejo de móveis e eletrodomésticos do Brasil no período de 2004 2010. Visando alcançá-lo, foi construído um modelo analítico a partir de uma adaptação do paradigma Estrutura-Conduta-Desempenho, às forças de mudança de Weston &Weav

24. Evolução e ecologia de tricomas em Bignonieae (Bignoniaceae): estruturas morfológicas de defesa anti-herbivoria? / Evolution and ecology of trichomes in Bignonieae (Bignoniaceae): morphological structures of anti-herbivory defense?
This thesis focused on the evolutionary-ecology of trichomes in the tribe Bignonieae (Bignoniaceae), and in the potential defensive role of these structures against herbivores. More specifically, we characterized four trichome morphotypes found in vegetative plant parts of representatives of the Bignonieae, as well as studied the macro-evolutionary patterns
