37. Investigation of the Interaction of 2-(2'-Hydroxyphenyl)-benzoxazoles and their Derivatives with B-DNA by Docking and Molecular Dynamics
In this work we carried out a study covering conformational analysis, docking calculations and molecular dynamics (MD) simulations of six excited state intramolecular proton transfer (ESIPT)-fluorescent 2-(2'-hydroxyphenyl)-benzoxazoles, interacting with the Dickerson-Drew (d(CGCGAATTCGCG)2) dodecamer in B-DNA conformation. In the analysis of the molecular d

38. Subjective time perception is affected by different durations of exposure to abstract paintings that represent human movement
Time perception can be affected by real emotional pictures of people that evoke different levels of arousal. Figurative artwork images of body postures that imply movement with different intensities and evoke different levels of arousal can modulate the perception of time. The present study investigated whether abstract paintings that represent motion in dif

39. Hardware embedded fiber sensor interrogation system using intensive digital signal processing
The description of an interrogation system for fiber Bragg grating sensors is reported. The full implementation in hardware of the required signal processing is proposed and made publicly available. The hardware description is implemented in a field programmable gate array (FPGA) development kit and the processing units allow one to control an optoelectronic

40. Three theories for reconciling the linearity of egocentric distance perception with distortion of shape on the ground plane
The focus here is on the paradoxical finding that whereas visually perceived egocentric distance is proportional to physical distance out to at least 20 m under full-cue viewing, there are large distortions of shape within the same range, reflecting a large anisotropy of depth and frontal extents on the ground plane. Three theories of visual space perception

41. Measurement of ethanol subsidies and associated economic distortions: an analysis of Brazilian and U.S. policies
Este estudo tem por objetivos medir os valores dos subsídios equivalentes das políticas de apoio ao etanol nos Estados Unidos e no Brasil e estimar a magnitude das distorções econômicas por eles causadas. Para o período entre 2002 e 2011, os valores anuais médios destes subsídios foram de US$7,2 bilhões nos Estados Unidos e US$2,1 bilhões no Brasil

42. Laboratory animal: biological reagent or living being?
The duties of humans toward non-human animals and their rights in society have been debated for a long time. However, a discussion on the terminology used for the identification of laboratory animals is usually not considered, although the employment of inadequate terminology may generate disastrous consequences for the animals before, during, and after the

43. Accuracy of face castings employing thermoplastic custom trays for facial molding
AIM: To evaluate the dimensional stability of a new facial molding technique using thermoplastic custom molding tray. METHODS: The designs established demarcation of facial anthropometrics landmarks, making linear measurements with a digital caliper. Facial molding was carried out using thermoplastic custom trays, constructing a facial plaster cast with the

44. Fatigue analysis and life prediction of composite highway bridge decks under traffic loading
Steel and composite (steel-concrete) highway bridges are currently subjected to dynamic actions of variable magnitude due to convoy of vehicles crossing on the deck pavement. These dynamic actions can generate the nucleation of fractures or even their propagation on the bridge deck structure. Proper consideration of all of the aspects mentioned pointed our t

45. Estudo de distorções em soldagem com uso de técnicas numéricas e de otimização / Study of distortion in welding by using numerical and optimization techniques
The occurrence of distortions of structures is common during welding. Such distortions are more severe in the case of large structures, such as shipbuilding. Since distortions can increase manufacturing costs and time during shipbuilding, a thorough study of causes and consequences of distortions is necessary. Therefore, this work aims to study the distortio

46. Justiça na escola e regulação institucional em redes de ensino do estado de São Paulo / Justice in school and institutional regulation in the elementary educational system of the State of Sao Paulo
This dissertation aims to contribute to the debate on principles and ways to make elementary schools fairer by reducing educational inequalities. It studies school practices and the implementation of educational policies in fairer municipal elementary school systems in São Paulo State. Fairer municipal elementary school systems are defined according to Dube

47. Optimized microlens-array geometry for Hartmann-Shack wavefront sensor: design, fabrication and test
The Hartmann-Shack (H-S) wavefront sensor is now deployed in many different fields, from astronomy to industrial inspection, where the quality of optical media or components can be measured by the distortions (wavefront aberrations) they impart on a wavefront transmitted or reflected by them. In ophthalmology, this sensor is a core component of major aberrom

48. Measuring bacterial cells size with AFM
Atomic Force Microscopy (AFM) can be used to obtain high-resolution topographical images of bacteria revealing surface details and cell integrity. During scanning however, the interactions between the AFM probe and the membrane results in distortion of the images. Such distortions or artifacts are the result of geometrical effects related to bacterial cell h
