Evolució de la línia de costa a dues platges encaixades: Es Domingos Grans i Es Domingos Petits (2002-2019)
No full text[cat] S’analitza l’evolució de la línia de costa i la variabilitat espacial de dues platges encaixades
micromareals i d’ambient poc energètic (mitjana d’onatge = 0’71 m Hs) del llevant de Mallorca
(Es Domingos Grans i Es Domingos Petits). S’han utilitzat orto-fotos de 2002 fins a 2019, per
digitalitzar 7 línies de costa a cada platja. Mitjançant l’eina DSAS s’han calculat les taxes de
canvi de la línia de costa, i els canvis en la superfície de la platja seca. Els resultats obtinguts
indiquen que les dues platges presenten una correlació lineal positiva alta (R2=0’86) en la
seva evolució, per tant tenen un comportament morfo dinàmic similar. El paràmetre Shoreline
Change Envelope determina una variabilitat de línia de costa de 36 m (Es Domingos Petits) i
25 m (Es Domingos Grans), la variabilitat és major a n’Es Domingos Petits ja que està
exposada als onatges més septentrionals, més freqüents. L’àrea d’estudi presenta una
tendència general d’acreció amb indicadors mitjans de Linear Regression Rate elevats (1’19
m any-1 a 1’23 m any-1). La superfície de platja seca d’ambdues platges (2019) és superior al
seu estat inicial, encara que durant els 18 anys estudiats, hi ha hagut dos períodes erosius
on aquesta s’ha reduït (2011-2012 i 2012-2015). A més, observant l’estat inicial de les platges
(2002) i les dades d’onatges màxims dels mesos anteriors, es podria que els temporals
extrems tenen certa relació amb els episodis d’erosió.[eng] This work deals with the coastline evolution and spatial variability of two microtidal low energy
(mean wave = 0.71 m Hs) pocket beaches in the east coast of Mallorca (Es Domingos Grans
and Es Domingos Petits). Orthophotos from 2002 to 2019, were analyzed to digitalize seven
shorelines for each beach. With the use of DSAS tool, the rates of change throughout coastline
were able to be calculated, as well as the changes in the surface of the subaerial beach. The
results obtained indicate that the two beaches have a high positive linear correlation (R2=0.86)
in their evolution, thus resulting in similar morpho-dynamic behavior. The Shoreline Change
Envelope parameter determines a variability of 36 m (Es Domingos Petits) and 25 m (Es
Domingos Grans), the variability is greater in Es Domingos Petits since it is exposed to more
northern and frequent waves. The study area shows a general tendency to increase with
medium Linear Regression Rate indicators (1.19 m any-1 to 1.23 m any-1). The area of
subaerial beach of both sites (2019) is higher than its initial status, although during the 18
years studied, there have been two periods of erosion in this area (2011-2012 and 2012-
2015). Moreover, observing the initial status of the beaches (2002) and the maximum data
from the previous months, it is possible that the extreme seasons are closely related to the
episodes of erosion
Entre o extraordinário e o cotidiano: os processos decisórios dos agricultores assentados: um estudo de caso do Assentamento Domingos Carvalho (Rio Negrinho/SC)
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias. Programa de Pós-Graduação em Agroecossistemas.Ao serem assentados numa determinada área, os agricultores beneficiários do processo de reforma agrária se vêem na contingência de estabelecer novas relações com o meio que passam a ocupar e reestruturar seus sistemas produtivos. Na definição e conformação desses sistemas, diversos fatores influenciam e direcionam os processos decisórios associados a eles. A presente dissertação tem por objetivo discutir e apontar alguns desses fatores cuja influência é mais marcante. Para tanto, parte-se da análise do Assentamento Domingos Carvalho, localizado no município de Rio Negrinho/SC. A pesquisa foi realizada por meio de observação participante e de entrevistas semi-estruturadas com os assentados, técnicos do Incra, do Icepa, do Projeto Lumiar e um membro da Coordenação Estadual do MST. A análise das informações obtidas aponta as questões internas, inerentes aos próprios assentados (especialmente a trajetória de vida e as perspectivas de futuro) como predisponentes ou mesmo, em alguns casos, condicionantes para a adoção de um determinado sistema agrícola. A ausência dos atores sociais externos ao assentamento em momentos cruciais do processo de desenvolvimento, foi um fator que estimulou o abandono de atividades "novas" (como a olericultura e a bovinocultura de leite) e o retorno àquelas "tradicionais" (principalmente o milho e o feijão), cujo itinerário técnico é de domínio dos agricultores. A motivação para a adoção desses cultivos ultrapassa razões meramente objetivas e utilitaristas, estando baseada também numa valorização simbólica e subjetiva atribuída a eles

Domingos Antunes Portugal: un jurista barroco
No full textDomingos Antunes fue un jurista portugués del Barroco. Defensor de la «Restauraçâo» portuguesa tras su independencia de Castilla en 1640, fue un autor que supo servirse de todos los fundamentos de la ciencia que había recibido. Utilizando una institución típica del derecho privado, como es la donación, se introduce en el complejo mundo de las ideas políticas; su obra nos conduce a la paradoja de poder hablar de la existencia de una escuela portuguesa del Derecho Internacional a raíz de la labor de este jurista que fue esencialmente civilista. Domingos Antunes fue un ejemplo de simbiosis de las culturas española y portuguesa que caminaron juntas... (Ver más) en tiempos de una convivencia muy difícil

Design for healthcare in current and future cities: Exploring assessment tools and methods for evaluating sustainability and inclusion in healthcare complex infrastructures
No full textGiven the pressing demand for hospitals to embody innovation and adaptability, it is significant that the majority of these institutions already reached the end of their estimated optimal lifespan. This situation prompts a critical inquiry into how to integrate both the physical, organizational, and social qualities of the healthcare environment and how to analyze the data collected within hospitals, to achieve the objective of creating sustainable cities. This paper explores the development and application of evidence-based tools in healthcare-built environments, focusing on enhancing quality, sustainability, and user-centered experiences. Specifically, it describes the methodological evolution of two innovative tools developed within research projects, specifically focusing on the assessment of sustainability and inclusion criteria in complex infrastructures for health. Based on different methodological steps, these tools provide comprehensive data collection and reliable analysis due to their development and criteria elicitation methods including Systematic Literature Review, Assessment Tool Review, Best Practices Analysis as well as Weighting Approach with multiple criteria analysis to support decision-making, emphasizing a collaborative, multidisciplinary approach to address future healthcare challenges. The findings highlight the implications of such tools in influencing policy, advocating for a holistic view in healthcare design and operation to better meet diverse user needs and therefore contribute to the sustainable design of current and future cities
A comparison of 3D poly(e-caprolactone) tissue engineering scaffolds produced with conventional and additive manufacturing techniques by means of quantitative analysis of SR m-CT images
No full textThe technique used to produce a 3D tissue engineering (TE) scaffold is of fundamental
importance in order to guarantee its proper morphological characteristics. An accurate assessment of the resulting structural properties is therefore crucial in order to evaluate the effectiveness of the produced scaffold. Synchrotron radiation (SR) computed microtomography (m-CT) combined with further image analysis seems to be one of the most effective techniques to this aim. However, a quantitative assessment of the morphological parameters directly from the reconstructed images
is a non trivial task. This study considers two different poly(e-caprolactone) (PCL) scaffolds fabricated with a conventional technique (Solvent Casting Particulate Leaching, SCPL) and an additive manufacturing (AM) technique (BioCell Printing), respectively. With the first technique it is possible
to produce scaffolds with random, non-regular, rounded pore geometry. The AM technique instead is able to produce scaffolds with square-shaped interconnected pores of regular dimension. Therefore, the final morphology of the AM scaffolds can be predicted and the resulting model can
be used for the validation of the applied imaging and image analysis protocols. It is here reported a SR m-CT image analysis approach that is able to effectively and accurately reveal the differences
in the pore- and throat-size distributions as well as connectivity of both AM and SCPL scaffolds

Plakortis spinalis sp. nov.: MNRJ 8597, Sapata Cave, Fernando de Noronha Archipelago, Brazil. Diagnosis. Plakortis thinly encrusting, light brown in vivo, with a tangential ectosomal skeleton disorganized or vaguely reticulate, and a disorganized choanosomal skeleton. Both ectosomal and subectosomal lacunae are absent. Spicules are smooth diods and tuberculate microrhabds, together with siliceous spheres; triods are absent. Description. Shape thinly encrusting, up to 4.5 by 3.0 cm wide and 0.5 cm thick (Fig. 2 A, B). Color in vivo light brown with dark patches and light brown to yellowish-cream internally; it becomes all light brown or grayishcream in alcohol. Surface smooth but irregular, uneven. Oscules circular or elliptical, 1–3 mm in diameter, with a slightly elevated rim in vivo and contracted in preserved specimens. Consistency firm, cartilaginous to compressible. Skeleton. Tangential ectosomal skeleton disorganized, but vaguely reticulated in parts of some specimens (Fig. 2 C). Both ectosomal and subectosomal lacunae are absent. Ectosome and choanosome undifferentiated. Choanosomal skeleton disorganized, with few traces of reticulation (Fig. 2 D). Spicules. Diods thin, sinuous, smooth, with rounded or sharp ends. The central bent varies from slightly to strongly marked, some very irregular (Fig. 2 E): 28-55 - 76 / 1-1.9 - 3 µm (n= 80). Microrhabds slightly sinuous, irregular, and typically tuberculate (Fig. 2 F): 1-6.2 - 18 / 0.5-2.4 -3.0 µm (n= 80). Spheres smooth, ovoid and flattened are common (Fig. 2 F): 1-6.2 - 35 µm in diameter (n= 80). Triods absent. Habitat and ecology. Specimens were collected between 4 and 13 m depth on vertical walls, always on hard substrate. Small calcareous sponges were observed growing on their surface. Distribution. Endemic from São Pedro e São Paulo Archipelago, NE Brazil (Fig. 1). Taxonomic remarks. Plakortis petrupaulensis sp. nov. belongs to the group of Plakortis with microrhabds, which also includes P. microrhabdifera, P. lita de Laubenfels 1954, P. hooperi Muricy 2011 and P. m y r a e Ereskovsky, Lavrov & Willenz 2013. The new species is mostly similar to P. microrhabdifera in the brown color, smooth surface, disorganized choanosomal skeleton and absence of triods. They differ by the larger size of diods (50–101 µm long), a double tangential ectosomal reticulation, and the presence of non-tuberculate microrhabds in P. microrhabdifera (cf. Moraes & Muricy 2003). Plakortis hooperi is distinguished by a lighter color, presence of subectosomal lacunae and triods, larger diod size (79–148 µm) and absence of tubercles in microrhabds (Muricy 2011). Plakortis lita differs from P. petrupaulensis sp. nov. by its dark color (dark brown or black), slimy surface, reticulate tangential ectosomal skeleton, non-tuberculate microrhabds, and presence of triods (de Laubenfels 1954; Muricy 2011). Plakortis myrae differs from the new species by the presence of triods, larger diods (66–119 µm) and smooth microrhabds. The new species differs from all other species of Plakortis by the presence of tuberculate microrhabds. Etymology. The name petrupaulensis refers to the type locality of the species, São Pedro e São Paulo Archipelago, in NE Brazil.Published as part of Domingos, Celso, Moraes, Fernando & Muricy, Guilherme, 2013, Four new species of Plakinidae (Porifera: Homoscleromorpha) from Brazil, pp. 530-544 in Zootaxa 3718 (6) on page 533, DOI: 10.11646/zootaxa.3718.6.2, http://zenodo.org/record/21889
