A new species of Pseudopaludicola Miranda-Ribeiro (Leiuperinae: Leptodactylidae: Anura) from the Cerrado of southeastern Brazil with a distinctive advertisement call pattern

A new species of Pseudopaludicola is described from the Cerrado of southeastern Brazil. The new taxon is diagnosed from the P. pusilla species group by the absence of either T-shaped terminal phalanges or toe tips expanded, and promptly distinguished from all (13) recognized taxa currently assigned to Pseudopaludicola by possessing isolated (instead of regular call series), long (117-187 ms) and non-pulsed advertisement calls.

Intervention Based Exclusively on Stage- Matched Printed EducationalMaterials Regarding Healthy Eating Does Not Result in Changes to Adolescents' Dietary Behavior

Purpose. To assess the impact of a six-month stage-based intervention on fruit and vegetable intake, regarding perceived benefits and barriers, and self-efficacy among adolescents. Design. Randomized treatment-control, pre-post design. Subjects/ Setting. Schools were randomized between control and experimental groups. 860 adolescents from ten public schools in Bras ' ilia, Federal District, Brazil were evaluated at baseline; 771 (81%) completed the study. Intervention. Experimental group received monthly magazines and newsletters aimed at promotion of healthy eating. Measures. Self-reported fruit and vegetable intake, stages of change, self-efficacy and decisional balance scores were evaluated at baseline and post-intervention in both groups. Analysis. The effectiveness of the intervention was evaluated using the analysis of covariance model (ANCOVA) and repeated measurement analysis by means of weighted least squares. Comparison between the proportions of adolescents who advanced through the stages during the intervention was performed using the Mantel-Haenszel chi-square test. Results. After adjusting for sex and age, study variables showed no modifications through the proposed intervention. There was no statistical difference in participant mobility in the intervention and control groups between the stages of change, throughout the study. Conclusion. A nutritional intervention based exclusively on distribution of stage-matched printed educational materials was insufficient to change adolescents' dietary behavior.

Energy harvesting from piezoelectric devices embedded in a 3D printed wing

This thesis work has been carried out at Clarkson University in Potsdam NY, USA and involved the design of a low elongation wing, consisting of parts made by polylactide (PLA) using the fused deposition model (FDM) technology of Rapid Prototyping, then assembled together in a thin aluminum spar. The aim of the research is to evaluate the feasibility of collecting electrical energy by converting mechanical energy from the vibration of the wing flutter. With this aim piezoelectric stripes were glued in the inner part of the wing, as well as on the aluminum spar, as monomorphic configuration. During the phases of the project, particular attention was given to the geometry and the materials used, in order to trigger the flutter for low flow velocity. The CAD software SolidWorks® was used for the design of the wing and then the drawings were sent to the Clarkson machine shop in order to to produce the parts required by the wing assembly. FEM simulations were performed, using software MSC NASTRAN/PATRAN®, to evaluate the stiffness of the whole wing as well as the natural vibration modes of the structure. These data, in a first approximation, were used to predict the flutter speed. Finally, experimental tests in the Clarkson wind tunnel facility were carried out in order to validate the results obtained from FEM analysis. The power collected by the piezoelectrics under flutter condition was addressed by tuning the resistors downstream the electronic circuit of the piezoelectrics.

Printed Narrative: The Festival Books for Archduke Ernest of Austria from Brussels and Antwerp 1594

Workshop „The Narrative in Eastern and Western Art“, Graduate School of Letters, Kyoto, 2-5 December 2013 Abstract by Ivo Raband, University of Berne Printed Narrative: The Festival Books for Ernest of Austria from Brussels and Antwerp 1594 During the early modern period the medium of the festival book became increasingly more important as an object of ‘political narration’ throughout Europe. Focusing on Netherlandish examples from the sixteenth and seventeenth centuries, my talk will focus on the festival books printed for the Joyous Entries of Archduke Ernest of Austria (1553–1595). Ernest was appointed Governor General of the Netherlands by King Philipp II in 1593, being the first Habsburg Prince to reside in Brussels since 30 years. In Brussels and Antwerp, the Archduke was greeted with the traditional Blijde Imkomst, Joyous Entry, which dates back to the fourteenth century and was a necessity to actually become the sovereign of Brabant and Antwerp and to uphold the privileges of the cities. Decorated with ephemeral triumphal arches, stages, and tableaux vivants, both cities welcomed Ernest and, at the same time, demonstrated their civic self-assurance and negotiated their statuses. In honor of these events of civic power, the city magistrates commissioned festival books. These books combine a Latin text with a description of the events and the ephemeral structures, including circa 30 engravings and etchings. Being the only visual manifestation of the Joyous Entries, the books became important representational objects. The prints featured in festival books will be my point of departure for discussing the importance of narrative political prints and the concept of the early modern festival book as a ‘political object’. By comparing the prints from Ernest’s entries with others from the period between 1549 and 1635, I will show how the prints became as important as the event itself. Thus, I want to pose the question of whether it would have been possible to substitute a printed version of the event for the actual ceremony.
