Abstract

The paper emphasizes the relevance of university extension programs in professional training within graduate education institutions, focusing on participation in a prison education extension project. The study aimed to investigate the contributions of extension programs to the development and mobilization of professional knowledge during the initial training of a Mathematics teacher, based on Maurice Tardif's framework on teacher knowledge. The roles assigned to Brazilian university extension programs and their potential in teacher education are discussed. Using the (auto)biographical method, we analyzed the contributions of extension activities to the initial training of a Mathematics teacher. The results revealed that extension programs foster the mobilization of diverse teaching knowledge in various contexts and moments, constituting a significant formative experience. Furthermore, the study highlighted its role in shaping the extension participant's professional identity, transforming the "personal self" into the "professional self". [ABSTRACT FROM AUTHOR]

15. ANÁLISE DAS TENSÕES NODAIS NOS ENSAIOS DE BLÉVOT E FRÉMY.

Author

DELALIBERA, R. G., SILVA, J. C. G., GIONGO, J. S., and SILVA, A. A. S.

Abstract

For design of pile caps, strut and tie models are often adopted and have ample experimental support. Current norms present resistance limits different from the formulations proposed by the studies of Blévot and Frémy (1967), presenting conservative values. Thus, in order to analyze the behavior of the stresses in the nodal regions, an analytical analysis of the pile caps tested by Blévot and Frémy (1967) was carried out using the limits presented by the French researchers and those recommended by the main standard codes, in addition to other limits proposed by other researchers. With the results found, divergences in the results were observed. [ABSTRACT FROM AUTHOR]

Abstract

The equatorial cold tongue in the Pacific Ocean has been intensely studied during the last decades as it plays an important role in air--sea interactions and climate issues. Recently, Warner et al. revealed gravity currents apparently originating in tropical instability waves. Both phenomena have strong dissipation rates and were considered to play a significant role in cascading energy from the mesoscale to smaller horizontal scales, as well as to vertical scales less than 1 m. Here, we present Sentinel-3 satellite observations of internal solitary waves (ISWs) in the Pacific cold tongue near the equator, in a zonal band stretching from 2108 to 2658E, away from any steep bottom topography. Within this band these waves propagate in multiple directions. Some of the waves' characteristics, such as the distance between wave crests, crest lengths, and time scales, are estimated from satellite observations. In total we identify 116 ISW trains during one full year (2020), with typical distances between crests of 1500 m and crest lengths of hundreds of kilometers. These ISW trains appear to be generated by buoyant gravity currents having sharp fronts detectable in thermal infrared satellite images. A 2D numerical model confirms that resonantly generated nonlinear internal waves with amplitudes of O(10) m may be continuously initiated at the fronts of advancing gravity currents.

Abstract

In this study, the scattering mechanisms associated to internal waves (IWs) are investigated at L-band. IWs represent key geophysical factors for sea-air heat exchange and play a paramount role in the biological primary production and in the understanding of the evolution of climate ecosystem. In addition, a better understanding of IWs microwave scattering mechanisms can improve the modeling capability and, therefore, can boost the development on advanced synthetic aperture radar (SAR)-based added-value products to mitigate the risk for offshore drilling operations and aquaculture activities associated to IWs. The analysis of L-band multi-polarization SAR scattering of IWs under the influence of surface current straining is performed using a meaningful full-polarimetric Advanced Land Observing Satellite Phased Array type L-band 1 SAR data set collected over IWs observed under different imaging and wind conditions. Time and space co-located ancillary information is also available. Experimental results demonstrate that the non-polarized scattering mechanisms constitute a significant contribution to the total IW backscattering, especially in the case of surface current gradients owing to IWs (about 48–57%). It is also found that the non-polarized scattering contribution associated to IW concentrates along the wave crests, i.e. it is at least 60% larger than the one observed along the wave troughs. In addition, considering the IW traveling directions relative to that of the wind, the non-polarized scattering contribution associated to IWs is more remarkable at upwind direction while it is less significant at down/crosswind directions. The non-polarized scattering mechanisms also calls for a modulation induced by IWs which is much more significant,i.e. at least three times, that the one that characterizes the polarized scattering mechanism.
