High resolution seismic stratigraphy and Mass Transport Deposits of the proximal continental margin, offshore Quarteira, South Portugal: Preliminary Results.

More than 300 nautical miles of multichannel seismic reflection data were acquired in the scope of the ASTARTE project (Assessment Strategy and Risk Reduction for Tsunamis in Europe), off Quarteira, Algarve, South Portugal. The main goal of this very high resolution multichannel seismic survey was to obtain high-resolution images of the sedimentary record to try to discern the existence of high energy events, possibly tsunami backwash deposits associated with large magnitude earthquakes generated at the Africa-Eurasia plate boundary This seismic dataset was processed at the Instituto Português do Mar e da Atmosfera (IPMA), with the SeisSpace PROMAX Seismic Processing software. A tailor-made processing flow was applied, focusing in the removal of the seafloor multiple and in the enhancement of the superficial layers. A sparker source, using with 300 J of energy and a fire rate of 0,5 s was used onboard Xunauta, an 18 m long vessel. The preliminary seismostratigraphic interpretation of the Algarve ASTARTE seismic dataset allowed the identification of a complex sequence seismic units of progradational and agradational bodies as well as Mass Transported Deposits (MTD). The MTD package of sediments has a very complex internal structure, 20m of thickness, is apparently spatially controlled by an escarpment probably associated to past sea level low stands. The MTD covers across an area, approximately parallel to an ancient coastline, with >30 km (length) x 5 km (across).This work was developed as part of the project ASTARTE (603839 FP7) supported by the grant agreement No 603839 of the European Union’s Seventh.

Geografia portuguesa, trópicos e colonialismo tardio: proposta e resultados de um dossier

[Excerto] Apesar de alguns estudos parcelares publicados nos últimos anos, ainda não foi realizada uma leitura abrangente da Geografia portuguesa que permita compreender o papel do discurso geográfico em «situação colonial» e a forma como este mesmo discurso parece ter sido revalorizado à medida que se agravou o clima internacional em torno da política colonial portuguesa, a partir de meados da década de 1950 (Pimenta et al., 2011; Oliveira e Paiva, 2019; Sarmento, 2019). A teoria pós-colonial ensina-nos que a colonização não só transformou o mundo colonizado, como também transformou profundamente as sociedades colonizadoras, colocando assim a questão do colonialismo no cerne da modernidade europeia (Driver, 2006; Butlin, 2009). Isto significa que partimos para este dossier assumindo como propósito fundamental reunir um conjunto de análises críticas sobre alguns dos mais representativos discursos e práticas da Geografia portuguesa da época sobre o «mundo tropical». Fazendo-o, propomo-nos contribuir para a renovação epistemológica da própria disciplina, que, em nosso entender – e em linha com Driver (2006), Bruneau (2008), Jazeel (2014), Clayton e Kumar (2019) e Clayton (2020) –, ainda não refletiu suficientemente sobre este momento muito complexo da sua história.A pesquisa para este artigo foi financiada pela Fundação para a Ciência e a Tecnologia, I.P. (Portugal), no âmbito do projecto “RegRural - Regular o Rural Colonial: Aldeamento de Guerra no Colonialismo Português Tardio” (ref.ª EXPL/GES-URB/1284/2021), Centro de Estudos Sociais/Universidade de Coimbra

TytoTagus Project: Common Barn Owl post-fledging dispersal and survival in the Tagus Valley, Portugal

The Tagus Estuary hosts a high concentration of juvenile Common Barn Owls (Tyto alba) during the post-fledging dispersal period with more than 15 owls/km detected along roads in the south floodplain of Vila Franca de Xira (SF). The Tyto Tagus project examined the origin of these birds with six re-sightings of 136 colour-ringed nestlings (2006–2008) and subsequently (2009-2012) with 41 VHF radio-marked juveniles from three areas: 16 in Benavente, 13 in the SF and 12 in Coruche. Five re-sightings were of colour-ringed juveniles from nests in Benavente (11 km away. Juvenile Common Barn Owls mainly roosted in trees along roadsides and riparian areas but also in forest patches (i.e., in mixed stands of cork oak (Quercus suber) and pine (Pinus spp.), montados and pine forests) adjacent to open agricultural areas. Between 7.3% and 43.9% of the owls survived the post-fledging dispersal period. Future studies should assess the impact of road mortality near the SF and consider the use of new technologies to track juveniles until they nest

Cytogenetic and molecular characterization of almond trees treated with plant biostimulants or boron-based fertilizers

Almond is highly produced in the NE of Portugal, where late frosts during flowering, low precipitation, and high tempera- ture in summer affect productivity and quality. Despite the use of late-flowering cultivars, plant biostimulants (PBs) and boron-based fertilizers can also be used to improve cell division, vegetative growth, photoassimilates rate, and nutritional status. PBs are widely used in some food crops, but the evaluation of their effects is still scarce. We treated three-year- old almond trees of cv. ‘Vairo,’ growing in a rainfed orchard in the NE of Portugal, with four individual treatments: two PBs (based on seaweed extract and free amino acids) and two boron-based fertilizers (applied on soil and leaves). Three monthly applications of seaweed extract (AN), free amino acids (AA), and boron ethanolamine (BE) were made. A single application of boron on the soil (BS) was made. Leaf samples were collected in treated and untreated (control) trees in cytogenetic and molecular analyses through the summer of 2019. The mitotic cell cycle analysis was performed to prepare mesophyll dividing cells stained with silver nitrate, and the molecular stability was assessed with five marker systems. This work aimed to extrapolate which individual treatment conferred higher mitotic cell cycle regularity and molecular stability. The cytogenetic and molecular data achieved in the cv. ‘Vairo,’ under the edaphoclimatic conditions studied, revealed that the individual treatments AA, BE, or BS induced higher leaf mitotic indexes, regular mitosis, and molecular stability, which might increase the photosynthetic area and production.This research was funded by national funds provided by the FCT/MCTES (“Fundação para a Ciência e a Tecnologia/ Ministério da Ciência, Tecnologia e Ensino Superior”) to the research units CIMO (UIDB/00690/2020) and CITAB (UIDB/04033/2020).

BIRDS AND SUSTAINABLE MANAGEMENT IN MEDITERRANEAN RIPARIAN AREAS: Bird studies in the RIPIDURABLE project

RIPIDURABLE is an INTERREG IIIC European Program involving 10 partners from Portugal, Spain, France and Greece. Scientists, technicians and local/regional authorities worked together to integrate knowledge, knowhow and practice, towards a rational conservation management of riparian zones. Birds can be used to characterize ecosystems, to monitor environmental changes or to assess results of restoration measures. We have conducted field surveys in order to assess breeding bird communities associated to riparian galleries in several watercourses, including issues as the relation with natural vegetation profiles, the influence of the surrounding matrix, the evolution with time or with habitat degradation, the effects of rehabilitation measures, and/or the importance of riparian galleries as ecological corridors for birds. Surveys at different space and time scales were carried out using standardised point count methods, on 8 watercourses in Portugal and France. We focused on different aspects of riparian breeding bird community variation: along a decreasing gradient of vegetal complexity (Tagus Basin), along an upstream-downstream gradient (Allier), with different surrounding landscapes (Sado, Guadiana and Tagus Basin), with time (Alcáçovas at a 10 years interval, Allier at 16 years interval), with management status (Vidourle), with time & management status (Rhône delta at a 12 years intervals), before & after river rehabilitation (Gandum). In addition we studied the dispersal of Barn Owls from upper Tagus Estuary along riparian corridors (TytoTagus Project), and also the importance of riparian habitats of the Guadiana basin on the autumn migration of trans-Saharan birds across the Iberian Peninsula. The RIPIDURABLE project offered the opportunity for further research currently included in national programs such as the Plan Loire Grandeur Nature which allows long term studies on riparian birds. Herein we briefly present some of the preliminary results of the bird studies carried out by partners from Portugal and France

Translucency and color differences of polycrystalline ceramic materials before and after layering

Objective: To evaluate the transmittance (%T) and color difference (∆E*) of six zirconia core materials compared to alumina, over eight colored substrates before and after ceramic application. Methods: Experimental groups (n=5) of standardized disk-shaped cores of alumina, white zirconia, medium-colored zirconia, Ice Translucent, and Prettau (white and D3 colored) were veneered to a uniform thickness to convenient color by layering. Their %T and ∆E* over eight different substrates were determined before and after glazing. Data were analyzed with Kruskal-Wallis and Mann-Whitney tests (α<0.05). Results: %T and ∆E* values were significantly different (p<0.001) before and after ceramic application for all materials. Regarding %T, Prettau white zirconia was the most affected, overpassing alumina. Colored zirconia cores decreased %T equally. In terms of ∆E*, zirconia materials initially performed high above the clinically acceptable threshold but were under it after ceramics application. White zirconia was the only material to perform below the clinical perceptibility threshold. Alumina initially performed under the clinically acceptable threshold for two substrates, but after ceramic application, only performed under the clinical perceptibility threshold over four. Substrates influenced ∆E* values of all core materials but were only evident on three of them. Conclusions: Core materials influenced %T and ∆E* values. Colored zirconia cores showed less %T than white cores and both less than alumina before and after ceramic application. After ceramic application, all materials performed under the clinically acceptable threshold over all the substrates. Substrates have more influence on ∆E* values before ceramic application

Determination of the Drag Coefficient of an Autonomous Solar Lighting Column Using Wind Tunnel Simulation and Computational Analysis

The Sun is the largest source of energy available and many studies for the development of technologies capable of harnessing this energy are constantly being conducted. Among the technologies developed are photovoltaic solar panels that have many applications and among them are the autonomous solar lighting columns that have been growing in popularity especially in urban and industrial environments. These columns are installed in open regions and have their structure exposed to the mechanical actions imposed by the wind, so they need to be correctly designed to support them. There are aerodynamic variables that must be determined for the design of these columns, especially the drag coefficient, a property linked to the geometry&nbsp; of a body, which represents its interaction with a flowing fluid. Due to the complexity of determining these variables, experimental methods are constantly used to obtain these values. Classically, wind tunnel simulations are used for this purpose, but they can be expensive and difficult to perform. Fluid dynamic computational analysis has been widely applied to replace physical analysis. In this work, the drag coefficient of an autonomous solar lighting column is determined by wind tunnel simulations and computational analysis. With the obtained results, a comparison is made to verify&nbsp; the fidelity of the data obtained by computational means when compared to those obtained through the wind tunnel simulations. Keywords: Drag coefficient, Wind tunnel simulations, Computational Fluid Dynamic analysis, Autonomous solar lighting column
