Abstract. We report measurements of electron spin echo envelope modulation (ESEEM) performed at millikelvin temperatures in a custom-built high-sensitivity spectrometer based on superconducting micro-resonators. The high quality factor and small mode volume (down to 0.2 pL) of the resonator allow to probe a small number of spins, down to 5 ⋅ 102. We measure 2-pulse ESEEM on two systems: erbium ions coupled to 183W nuclei in a natural-abundance CaWO4 crystal, and bismuth donors coupled to residual 29Si nuclei in a silicon substrate that was isotopically enriched in the 28Si isotope. We also measure 3- and 5-pulse ESEEM for the bismuth donors in silicon. Quantitative agreement is obtained for both the hyperfine coupling strength of proximal nuclei, and the nuclear spin concentration.
The three-dimensional life cycle of potential vorticity cutoffs: A global
ERA-interim climatology (1979–2017)
Authors: Portmann Raphael , Sprenger Michael , Wernli Heini
Published: July 2020

Abstract. The aim of this study is to explore the nature of potential vorticity (PV) cutoff life cycles. While climatological frequencies of such upper-level cyclonic vortices are well known, their life cycle and in particular their three-dimensional evolution is poorly understood. To address this gap, a method is introduced that allows tracking PV cutoffs as three-dimensional objects. As it is based on isentropic air parcel trajectories, the detailed evolution of the cutoffs on isentropic surfaces, including their associated cross-tropopause mass fluxes, can be analyzed. The novel method is applied to the ERA-interim dataset for the years 1979–2017 and the first global climatology of PV cutoffs is presented that is independent of the selection of a vertical level and identifies and tracks PV cutoffs as three-dimensonal features. More than 40 000 PV cutoff life cycles are identified and analyzed in the almost 40-year data set. Known frequency maxima of PV cutoffs are confirmed and, additionally, bands in subtropical areas in the summer hemispheres and a circumpolar band around Antarctica are identified. A detailed investigation of PV cutoff life cycles in different genesis regions reveals that PV cutoff genesis occurs as a result of distinct Rossby wave breaking scenarios. In addition, there is a remarkable regional variability of PV cutoff mobility, lifetimes and vertical evolution. This regional variability of PV cutoff behaviour can to some extent be explained by differences in cross-tropopause mass fluxes and the varying frequencies of different lysis scenarios on isentropic surfaces, i.e. diabatic decay and reabsorption to the stratospheric reservoir. It is found that, on a global average, reabsorption occurs about as frequently as diabatic decay, but on higher isentropic levels. Further, the temporal link between PV cutoffs and associated surface cyclones is investigated. Novel insights are that (i) the frequency and characteristics of this link strongly depend on the region, and (ii) PV cutoffs are frequently involved in surface cyclogenesis a few days after their formation. PV cutoffs forming from similar Rossby wave breaking scenarios in different regions also show remarkable similarities in other characteristics of their life cycle. Based on that, a classification of PV cutoff life cycles into three types is proposed: Type I forms from anticyclonic Rossby wave breaking equatorward of the jet stream, Type II is the result of anticyclonic Rossby wave breaking followed by cyclonic Rossby wave breaking between the polar and the subtropical jets, and Type III forms from cyclonic wave breaking in the storm track regions. While diabatic decay is particularly frequent for Types I and II, reabsorption dominates for the Type III life cycle.
The flow past a flatback airfoil with flow control devices: benchmarking numerical simulations against wind tunnel data
Authors: Papadakis George , Manolesos Marinos
Published: July 2020

Abstract. As wind turbines grow larger, the use of flatback
airfoils has become standard practice for the root region of the blades.
Flatback profiles provide higher lift and reduced sensitivity to soiling at
significantly higher drag values. A number of flow control devices have been
proposed to improve the performance of flatback profiles. In the present
study, the flow past a flatback airfoil at a chord Reynolds number of
1.5×106 with and without trailing edge flow control devices
is considered. Two different numerical approaches are applied, unsteady
Reynolds-Averaged Navier Stokes (RANS) simulations and detached eddy
simulations (DES). The computational predictions are compared against wind
tunnel measurements to assess the suitability of each method. The effect of
each flow control device on the flow is examined based on the DES results on
the finer mesh. Results agree well with the experimental findings and show
that a newly proposed flap device outperforms traditional solutions for
flatback airfoils. In terms of numerical modelling, the more expensive DES
approach is more suitable if the wake frequencies are of interest, but the
simplest 2D RANS simulations can provide acceptable load predictions.

Authors: Castellano García Manuel
Published: July 2020

Finalizar la guerra de Sucesión española fue una ardua tarea diplomática. Después de casi una década de conflicto y varios fracasos diplomáticos, fue esencial la apertura en el verano de 1710 de un canal bilateral y secreto a través de la cual Francia y Gran Bretaña, actuando al margen de sus respectivos aliados, llegaron a una serie de acuerdos preliminares clave para lograr la conclusión del conflicto. El objetivo de este artículo es aclarar dicho proceso de negociación mediante el examen de la delicada estructura en la que se concibieron los contactos secretos franco-británicos y ofrecer una visión global de una compleja negociación que definió de manera decisiva los acuerdos firmados en Utrecht.

Vibrio parahaemolyticus is a potentially pathogenic bacterium that occurs naturally in estuarine environments worldwide. This research aimed to investigate the occurrence of Vibrio parahaemolyticus in estuarine environments and determine the virulence profile in aquaculture environment by molecular techniques and conventional microbiological methods. The analysis included 64 samples of water (n=32) and sediment (n=32) collected in estuaries. The samples yielded 64 strains suspected to be V. parahaemolyticus. The isolates were submitted to biochemical identification using a dichotomous key and PCR for the detection of the species-specific gene tl. Virulence was assessed by testing for urea hydrolysis and ?-hemolysis in erythrocytes (Kanagawa phenomenon) and simultaneous detection of the genes tdh and trh. All but one of the isolates (63/64) were confirmed to be V. parahaemolyticus by genotypic detection of tl. The genes tdh and trh were detected in 57 and 19 isolates, respectively. The Kanagawa test was positive for 51 isolates. Only one isolate was positive for urease. The incidence of tdh/trh-positivity was very high in strains isolated from the environment. The present study demonstrates that the necessity to improve the knowledge of the ecology and pathogeny of V. parahaemolyticus.

Lagochilascariasis, described for the first time in 1909, is caused by a helminth nematode within the Lagochilascaris genus, and Ascarididae family, which mainly affects the underprivileged, especially among rural populations. Brazil presents more than 75% of the cases worldwide, mostly in the Amazon region, where the illness is considered emergent. The main clinical manifestation in humans is the appearance of subcutaneous purulent lesions normally found around the neck, mastoid and middle ear regions, the originating form is a painless granulomatous reaction that may have a chronic course and lead to death. Considering the paucity of reports on this helminthiasis, a bibliographic study was performed with the intent of consolidating information found systemized as etiology, epidemiology, pathogeny, clinical aspects, diagnostic, treatment, prophylaxis and control, as well as guiding health professionals in the resolution of human lagochilasacariasis cases. The present review reinforces the need for further studies on the subject, with a view to increasing the appropriate management of the disease and learning from it, to improve control, based on adequate knowledge of its natural cycle, as well as health education of the population.KEY WORDS: Emerging diseases; human lagochilasacariasis; infectious diseases.
Bilingual phonology in dichotic perception: A case study of Malayalam and English voicing
Authors: Mandal Sayantan , Best Catherine T. , Shaw Jason , Cutler Anne
Published: July 2020

Listeners often experience cocktail-party situations, encountering multiple ongoing conversations while tracking just one. Capturing the words spoken under such conditions requires selective attention and processing, which involves using phonetic details to discern phonological structure. How do bilinguals accomplish this in L1-L2 competition? We addressed that question using a dichotic listening task with fluent Malayalam-English bilinguals, in which they were presented with synchronized nonce words, one in each language in separate ears, with competing onsets of a labial stop (Malayalam) and a labial fricative (English), both voiced or both voiceless. They were required to attend to the Malayalam or the English item, in separate blocks, and report the initial consonant they heard. We found that perceptual intrusions from the unattended to the attended language were influenced by voicing, with more intrusions on voiced than voiceless trials. This result supports our proposal for the feature specification of consonants in Malayalam-English bilinguals, which makes use of privative features, underspecification and the “standard approach” to laryngeal features, as against “laryngeal realism”. Given this representational account, we observe that intrusions result from phonetic properties in the unattended signal being assimilated to the closest matching phonological category in the attended language, and are more likely for segments with a greater number of phonological feature specifications.
Linguistics in the Framework of Three-Dimensional Logo: Letter, Note, Numeral
Authors: Grigoryevich Antipenko Leonid
Published: July 2020

The task of the article is return prosody to linguistics, to turn linguistics to speech, to voice content. For this, linguistics rises to the logo. It is shown that the logo as such is divided into three hypostases: the verbal logo, the musical logo (melos) and mathematical logo. The results of objectifications (Entӓusserung, Gegenstӓndlichkeit in German) of these components are expressed respectively by letters, notes and numerals. Each of the three components has two aspects that the author calls styles. The verbal logo has a prosaic and poetic style; musical logo has vocal (voice) and musical-instrumental style; mathematical logo has a logical style and a historical style.  Martin Heidegger showed that the logo is inextricable linked with time. The projection of time on the created images  ̶  verbal and poetic (letters), musical (notes), mathematical (numеrals)  ̶  allows you to fill them with life, to give them a natural look. Thus, orientation to the logos leads the linguist to a wider understanding of the subject of linguistics in comparison with the previous, narrowed version of its interpretation.
Antibacterial Potential of Star Anise (Illicium verum Hook. f.) Against Food Pathogen Bacteria
Authors: EVELINE EVELINE , NOVITA AGUSTIN
Published: July 2020

Star anise (Illicium verum Hook. f.) is commonly used as spice and flavor enhancer in food. Previous research revealed the presence of active compound which could inhibit bacterial growth. Thus, in order to apply star anise as natural antibacterial agent in food product, a further research concerning antibacterial activity and stability of star anise was conducted. Crude extract of star anise was obtained using ethanol and acetone with maceration method for 3 days, then diluted to 10, 20, 30, 40, and 50% (w/v). Well diffusion was conducted against three food spoilage bacteria (Staphylococcus aureus, Escherichia coli, and Bacillus cereus). Extract from ethanol with 30% concentration was selected as the best extract in which inhibit more than 6 mm inhibition zone with MIC and MBC value: 1.59% and 6.36% (S. aureus), 1.04% and 4.18% (E. coli), and 0.59% and 2.39% (B. cereus). This selected extract was used to test the extract stability against 4 levels of heating temperature (60, 70, 80, and 90°C) for 2 levels of heating time (15 and 30 minutes), and 4 levels of pH (4, 5, 6, and 7). Based on our results, different heating treatment and pH caused extract instability. Star anise extract was more stable at 60°C for 15 minutes heating treatment and pH 4, which resulting the lowest inhibition zone reduction compared to control extract. Star anise extract was categorized as low toxic compound (LC50 = 212.09 ppm). Terpenoids (anethole, 2,6-dimethyl-6-(4-methyl-3-pentenyl)-2-norpinene, β-caryophyllene, β-bisabolene) was founded as major antibacterial compound in star anise extract; fatty acid (6-octadecenoic acid, hexadecanoic acid, stearic acid) and benzaldehyde (4-anisaldehyde, p-allylanisole) were also founded as minor compound.
Constructions of Dense Lattices of Full Diversity
Authors: Andrade A. A. , Ferrari A. J. , Interlando J. C. , Araujo R. R.
Published: July 2020

A lattice construction using Z-submodules of rings of integers of number ﬁelds is presented. The construction yields rotated versions of the laminated lattices A_n for n = 2,3,4,5,6, which are the densest lattices in their respective dimensions. The sphere packing density of a lattice is a function of its packing radius, which in turn can be directly calculated from the minimum squared Euclidean norm of the lattice. Norms in a lattice that is realized by a totally real number ﬁeld can be calculated by the trace form of the ﬁeld restricted to its ring of integers. Thus, in the present work, we also present the trace form of the maximal real subﬁeld of a cyclotomic ﬁeld. Our focus is on totally real number ﬁelds since their associated lattices have full diversity. Along with high packing density, the full diversity feature is desirable in lattices that are used for signal transmission over both Gaussian and Rayleigh fading channels.

Published: July 2020

Background: Male breast cancer (MBC) is an infrequent disease and a scarcely researched topic. Since the incidence of male breast cancer is increasing and so far, management advices have been concluded from results of trials in female patients, there has been a growing interest in this field of research. Objectives: In this study, we aimed to evaluate the general, radiological and pathological features of MBC patients. Patients and Methods: We retrospectively reviewed the medical records of MBC patients who had been referred to breast clinic, Shahid Motahari in Shiraz, Iran, between 2005 and 2018. Data regarding general characteristics of patients such as demographic information, age, and also past history of any cancer, family history of breast cancer, mammogram and ultrasound findings, stage, size and location of tumor, histopathology of tumor, metastasis, treatment modalities and follow-up time were attained by reviewing medical records. Results: Fifty-one patients with MBC were included with the mean age of 58.4 years. Invasive ductal carcinoma was the most prevalent pathologic type. By use of the Kaplan Meier survival estimate, survival probability of patients for each time interval after diagnosis was calculated. There was a decline over time until about 85 months after diagnosis when it reached a plateau state above 50%. Age, human epidermal growth factor receptor 2 (HER2) and metastasis showed to lower the survival time by increasing the hazard ratio. Only 13 patients had mammography and 22 had an ultrasound, which are less than 50% of the total number of patients. Conclusions: This study showed that there is still unfulfilled need to evaluate MBC in order to find the best management guidelines such as screening in high risk populations, diagnosis, treatment, and follow-up. Risk factor evaluation, survival time, and diagnostic radiologic modalities have not been well assessed in MBC so far.
Ingenio ilustrado: Agustín de Betancourt por Javier Rui Wamba
Authors: Rui Wamba Javier
Published: July 2020

"El ingeniero nace; pero, sobre todo, se hace. Y la curiosidad intelectual suele ser un estímulo esencial en su formación, en la búsqueda de conocimientos que serán los fundamentos de sus actividades futuras. Es el afán de conocimiento el que impulsó a Agustín de Betancourt, excepcional personaje, a dejar su isla natal, Tenerife, e iniciar un peregrinaje sin retorno. En Madrid, su primera parada, simultaneó el aprendizaje de Ciencias con los de dibujo y otras disciplinas artísticas. Estudió después Ingeniería, en la prestigiosa y exigente École des Ingénieurs des Ponts et Chaussées, viviendo durante más de cinco años en el París prerrevolucionario de aquellos agitados tiempos. Más adelante, residió tres años en la Inglaterra efervescente que alumbró la Revolución Industrial. De allá nos trajo la máquina de vapor de Watt y la convicción de que dicho artefacto transformaría el mundo. En la desconcertada España de la época, colaboró estrechamente con los Condes de Floridablanca y de Aranda. Creó el Gabinete de Máquinas del Retiro y promovió la construcción de infraestructuras esenciales. En 1802 logró hacer realidad un sueño nacido en Francia: fundó la Escuela de Ingenieros de Caminos y Canales siguiendo el modelo de la École francesa. Las turbulencias políticas anunciaban tiempos poco propicios para las ideas progresistas e ilustradas. La desastrosa monarquía restaurada se apresuró a cerrar Universidades y, en el modesto edificio de la Escuela de Caminos y Canales, se estableció otra de Tauromaquia. Toreros en lugar de ingenieros. Aquél no era el país que Agustín de Betancourt deseaba para todos. Tenía cincuenta años cuando atraído como otras ilustres personalidades europeas por el zar Alejandro I, se trasladó con su familia a San Petersburgo, llegando a pronto el equivalente a Ministro de Obras Públicas del Zar. Creó sin dilación una Escuela de Ingenieros para formar altos funcionarios."

Seldom can a single person be identified as the architect of relevant social initiatives. Agustín de Betancourt would be one of them. An exceptional and transcendent character, who still influences us today, because of the intellectual infrastructures that he created and his contribution to the configuration of a strong and competent, effective and honest Administration model are still felt. Its genes shape our present and have shaped our collective for more than 200 years, giving it personality and coherence.
Arquitectura e ingeniería

La historia de la tecnología da cuenta como los ingenieros y los arquitectos han ido moldeando su relación de trabajo a través de un largo proceso que tras el conflicto original del siglo XIX y el período de idealización del movimiento moderno tendió a una inevitable confluencia. Desde la segunda mitad del siglo XX muchos son los ejemplos de esta fructífera relación que nos lleva a subrayar el aspecto colectivo de la construcción que no será posible concebir a partir de entonces de manera individual. La aparición de perfiles de ingenieros próximos al diseño, o de arquitectos con solvencia técnica suficiente ayudan a difuminar ese límite que un visionario como Le Corbusier anticipó en su famoso dibujo publicado en el prefacio del libro “Precisiones respecto a un estado actual de la arquitectura y el urbanismo” en 1960. Los casos de Rice y Piano, Utzon y Waschmann, Kommendant y Kahn o incluso ya en la final del siglo XIX, Adler y Sulivan son ejemplos de estas parejas que no pueden desvincularse para entender su obra.

The history of technology accounts for how engineers and architects have shaped their working relationship through a long process that after the original conflict of the 19th century and the period of idealization of the modern movement tended to an inevitable confluence. Since the second half of the 20th century, there are many examples of this fruitful relationship that leads us to underline the collective aspect of construction that it will not be possible to conceive individually from then on. The appearance of profiles of engineers close to design, or of architects with sufficient technical solvency help to blur that limit that a visionary like Le Corbusier anticipated in his famous drawing published in the preface of the book “Precisions regarding a current state of architecture and urbanism ”in 1960. The cases of Rice and Piano, Utzon and Waschmann, Kommendant and Kahn or even as late as the end of the 19th century, Adler and Sulivan are examples of these couples that cannot be separated to understand their work.

El derecho a la vivienda en el casco antiguo de Barcelona
Authors: Feu Fontaiña Pablo
Published: July 2020

En el casco antiguo de Barcelona la vivienda está sufriendo una profunda mutación:

está pasando de ser un derecho a ser un negocio y eso está comportando la

mutación del propio modelo de ciudad. Lo más grave es que este fenómeno está

provocando la proliferación de prácticas abusivas contrarias a ley que vulneran

abiertamente el legítimo ejercicio de ese derecho. Para entender la dimensión del

problema, es necesario acotar primero cuál es el alcance del derecho a la vivienda.

En este artículo se hace un enfoque a la problemática del derecho a la vivienda

comprendiéndolo desde la normativa vigente y su aplicación y se proponen unas

soluciones que podrían coadyuvar a garantizar este derecho en un territorio tan

complejo como lo es la Ciutat Vella de Barcelona.

In the old city center of Barcelona, housing is experiencing a serious mutation. Residence

is no longer a right, instead is becoming a business. This transformation causes

evident mutations in the city’s particular model. Abusive practices related to the violation

of this right are persistent. In order to understand correctly the dimension of the

problem, it is necessary to first define the scope of the right to housing.

This article focuses on the issue of the right to housing by understanding it from the

current legislation and its application, also proposes solutions that could help to guarantee

this right in a convoluted territory as Ciutat Vella.
Sentido y significado del casco antiguo contemporáneo: el uso residencial como función a conservar
Authors: Ordóñez León Andrea
Published: July 2020

El presente artículo puntualiza en identificar el significado del casco antiguo

en la ciudad contemporánea y las nuevas perspectivas para abordarlo.

El análisis de la evolución de la ideas que han contribuido a la construcción

del concepto “centro histórico” y como se han traducido en la concepción de

estos espacios a través del tiempo, permiten identificar un cambio de paradigma

que surge con la globalización, fenómeno cuyos efectos están produciendo

profundos cambios en el sentido de los cascos antiguos; el mercado aprovechando

sus valores, los está convirtiendo en lugares de ocio y consumo.

A partir de estas reflexiones se plantea un nuevo enfoque para la recuperación

de estos territorios. Si la residencia es la función primaria de la ciudad, y esta

se encuentra amenazada, ¿por qué no pensar en un camino para mantener

el casco antiguo como lugar para vivir?, ya no a partir de la conservación de

sus valores formales o estéticos sino desde la observación de las calidades y

deficiencias de los ambientes habitados y los aspectos que el uso cotidiano

imprime en estos lugares.

This paper proposes the meaning of the historic city center in the contemporary

city and the new perspectives to approach it.The evolution of the ideas that have

contributed to the construction of the concept “historic city center” and how these

have been translated in the conception of these spaces, allows to identify a paradigm

shift that begins with globalization, whose effects are producing profound

changes in the sense of the old city cores, the market is taking advantage of its

values to turn them into places of leisure and consumption.

From these reflections a new approach for the recovery of these territories is proposed.

If the residence is the city´s primary function, and this is threatened, why not

think in a way to maintain the old town as a place to live, analyzing the qualities

and deficiencies of the inhabited environments and the aspects that the daily use

prints in these places.
Re-imaginar el centro para cambiar la vida: Ciutat Vella como obra del habitar a través del pensamiento de Henri Lefebvre
Authors: Jiménez-Pacheco Pedro
Published: July 2020

En el marco de su investigación doctoral acerca del “espacio radical humano” como propuesta teórico y crítica para superar la transición hacia el post-neoliberalismo urbano, el autor se pregunta si conviene seguir la vía de la rehabilitación del casco

antiguo para recuperar la vida, o si habrían otros principios urbanos que permitan reinventar el espacio histórico para cambiar el curso de las relaciones hacia una nueva vida social. En este sentido, la teoría completa del espacio social y crítica

de la vida cotidiana de Henri Lefebvre es un faro que ilumina ese puerto. Se parte de un marco crítico que consiste en un repaso estadístico hasta la actualidad para introducir el proceso de neoliberalización urbana y crisis de la centralidad en Barcelona.

Así, las ideas de Lefebvre permiten al autor: ordenar el análisis del fenómeno urbano y restituir el nivel del habitar; situar en el medio, la relación de dos proyectos lefebvrianos esenciales –la evolución de la crítica de la vida cotidiana traducida en el espacio-tiempo social– y finalmente, plantear un relato que problematiza y revela las posibilidades de un nuevo espacio en el centro histórico. Las conjunciones articulan un discurso emancipador de

In the framework of his doctoral research on “human radical space” as a theoretical and critical proposal to overcome the transition to urban post-neoliberalism, the author wonders

whether it is appropriate to follow the way of rehabilitation of the old town to recover life, or if there would be another urban principles that allow to reinvent the historical space to change the course of the relations towards a new social life. In this sense, the complete theory of social space and critique of everyday life of Henri Lefebvre is a beacon that illuminates that port. It starts from a critical frame that consists of a statistical review up to the present to introduce the process of urban neoliberalization and crisis of centrality in Barcelona.

Thus, Lefebvre’s ideas allow the author: to order the analysis of the urban phenomenon and restore the level of dwelling; to place in the middle, the relation of two essential Lefebvrian projects –the evolution of the critique of everyday life translated into social space-time– and finally, expose an essay that problematizes and reveals the possibilities of a new space in the historical centre. The conjunctions articulate an emancipatory discourse of a concrete urban reality in the old towns of the contemporary city.
Proyectar la residencia en el casco antiguo contemporáneo: los orígenes de la intervención de regeneración en la Ciutat Vella de Barcelona
Authors: Serra i Amengual Pere
Published: July 2020

El reciente proceso de regeneración de Ciutat Vella, materializado entre 1986 y 2004, se fundamenta en un modelo de centro histórico residencial social, fiel al papel que historicamente ha jugado el casco antiguo de Barcelona. Este proceso requirió un consenso institucional y social sin precedentes, y la creación de instrumentos específicos para gestionarlo.

Un centro histórico en el que a finales del siglo XX se promocionan más de 3.000 viviendas protegidas y se rehabilitan más de 30.000 viviendas privadas, no es un caso frecuente. Este impulso público está marcado por múltiples experiencias proyectuales que han servido para experimentar soluciones arquitectónicas, han consolidado un modelo de respeto a la trama histórica, y fundamentado en el proyecto urbano integral sobre el espacio público.

Este modelo residencial social ha sido útil para normalizar y estabilizar la población y la

pirámide de edades. Sin embargo el crecimiento del turismo y de la gentrificación, ponen

de relieve el déficit de un patrimonio público de vivienda de alquiler que permita intervenir

más activamente en los esfuerzos por mantener, en el futuro, este carácter residencial.

The recent process of Ciutat Vella’s regeneration, materialized between 1986 and

2004, is based on a model of historical social residential center, faithful to the

historical role of the old part of the city. This process required unprecedented institutional

and social consensus, and the creation of specific instruments to manage it.

At the end of the 20th century more than 3,000 protected homes are promoted

and more than 30 000 private homes are rehabilitated, it is not a frequent case.

This public impulse is marked by multiple project experiences that have served to

experiment with architectural solutions, have consolidated a model of respect for the

historical fabric, and based on the comprehensive urban project on public space.

This social residential model has been useful for normalizing and stabilizing the

population and the age pyramid. However, the growth of tourism and gentrification

highlights the deficit of a public housing rental property that allows a more active

involvement in efforts to maintain this residential character in the future.
Observar y documentar para planificar, proyectar y gestionar: la gestión de las transformaciones territoriales en América Latina
Authors: Llop Torné Carles Joan
Published: July 2020

El creciente proceso de urbanización mundial y la concentración demográfica y de recursos en las ciudades, demanda un nivel cada vez más alto de conocimiento, eficiencia en la organización, y acierto de proyecto y gestión de la ciudad por parte de los gobiernos. Las ciudades representan el lugar estratégico de articulación de las estructuras sociales, de modo que la habitabilidad tienda a desarrollarse a través de directrices sostenibles, base del proyecto de investigación colaborativa que se presenta.La figura de los gestores públicos, con capacidad innovadora y un nivel elevado de formación transversal, basada en conocimientos pluridisciplinares, debe ser muy tenida en cuenta para monitorear los nuevos proyectos urbanos y territoriales. Es en esta línea en la que el equipo de investigadores constituye un espacio de investigación, basado en el learning by doing, partiendo de las situaciones específicas de las ciudades y profundiza sobre una reflexión, que establece analogías, contraposiciones, y transmisión de experiencia del proyecto y gestión de ciudad entre diferentes contextos. Un enfoque de investigación está encaminado hacia la práctica profesional desde una visión renovada de los retos urbanos y disciplinares. Las líneas de investigación que se describen abordan temas claves del proyecto y la gestión urbana. Así mismo, la participación en redes de ciudades internacionales (y específicamente latinoamericanas) busca crear una base de intercambio de conocimiento y colaboración en el marco de la globalización de carácter estable y duradero.

The growing process of global urbanization and the concentration of population and resources in cities, demands an increasingly high level of knowledge, efficiency in the organization, and success in the project and management of the city by governments. Cities represent the strategic place of articulation of social structures, so that habitability tends to develop through sustainable guidelines, the basis of the collaborative research project presented. The figure of public managers, with innovative capacity and a high level of transversal training, based on multidisciplinary knowledge, must be taken into account to monitor new urban and territorial projects. It is in this line that the team of researchers constitutes a research space, based on learning by doing, based on the specific situations of the cities and deepens on a reflection, which establishes analogies, counterpositions, and transmission of project experience and city management between different contexts. A research approach is aimed at professional practice from a renewed vision of urban and disciplinary challenges. The lines of research described address key issues of the project and urban management. Likewise, participation in networks of international cities (and specifically Latin American) seeks to create a base for knowledge exchange and collaboration within the framework of globalization of a stable and lasting nature.
La vivienda de nuevo: indagaciones urbanísticas sobre las tramas residenciales de la ciudad contemporánea
Authors: Peremiquel Lluch Francisco
Published: July 2020

Desde la perspectiva urbanística, la vivienda y el espacio urbano residencial, el estudio de las tramas, la habitabilidad del espacio exterior, próximo y cotidiano, parece que no tiene la atención investigadora que merece. La ciudad como unidad delimitada y reconocible, ha desaparecido. Es una periferia inmensa, compuesta de fragmentos urbanos diversos, con diferentes niveles de urbanidad y urbanización, muchos de ellos vulnerables. A menudo, las deficiencias urbanas fomentan la degradación física y social del tejido, produciendo grandes desequilibrios. La aproximación morfológica confía en la forma, la geometría y la medida, como respuesta a los retos urbanos. La sostenibilidad se juega en la medida y geometría optimizada de las cosas urbanas. La calidad de la forma es la que permite la pervivencia en el tiempo y aporta la flexibilidad necesaria para la adaptación al cambio. El programa urbano es hoy genérico, con poca atención al lugar, al momento histórico o a la morfología resultante, y presta más atención a la viabilidad que a la sostenibilidad futura. De lo que se trata es de plantear un cambio de paradigma: un programa urbano orientado hacia un desarrollo duradero.

From the urban perspective, housing and residential urban space, the study of the plots, the habitability of outer space, close and daily, it seems that it does not have the research attention it deserves.The city as a delimited and recognizable unit has disappeared. It is an immense periphery, composed of diverse urban fragments, with different levels of urbanity and urbanization, many of them vulnerable. Often, urban deficiencies encourage the physical and social degradation of tissue, producing large imbalances.The morphological approach relies on form, geometry and measurement, as a response to urban challenges. Sustainability is played in the measure and optimized geometry of urban things. The quality of the form is what allows the survival in time and provides the necessary flexibility to adapt to change. The urban program is now generic, with little attention to the place, to the historical moment or to the resulting morphology, and pays more attention to viability than to future sustainability. The aim is to propose a paradigm shift: an urban program oriented towards lasting development.
Stuck in the middle. A geographical appraisal of the oldest insectivores – and a marsupial – from the Vallès-Penedès Basin (early Miocene, Catalonia, Spain)

The Vallès-Penedès Basin in Catalonia (NE Spain) forms a biogeographically important connection between central Europe and the Iberian Peninsula. Whereas this is well documented for the late middle and early late Miocene, the early Miocene sequence has received far less attention. New excavations yielded micromammal assemblages from the Ramblian and early Aragonian. Among the euliphotyhplans and metatherian studied, we recognize seven non-soricid species (Amphiperatherium frequens von Meyer, 1846, Galerix symeonidisi Doukas, 1986 and Galerix remmerti van den Hoek Ostende, 2003, Desmanodon daamsi van den Hoek Ostende, 1997, Heterosorex neumayrianus Schlosser, 1887, Chainodus sp., Plesiodimylus sp.) and six species of shrews (Paenelimnoecus sp., Miosorex sp., cf. Clapasorex, cf. Oligosorex, cf. Florinia sp. and Soricinae indet.). They confirm the intermediate position of the Vallès-Penedès also at the time of the older faunas, but show that differences with the Iberian inland were less pronounced. These differences can be explained by higher humidity in the coastal region, as indicated by the presence of dimylids. The differences between this coastal area and inland basin confirm the potential of coastal regions as migration corridors.
Características biométricas e Índices de condição da ostra-do-mangue Crassostrea rhizophorae (Guilding, 1828) do estuário do rio Ipojuca, PE, Brasil
Authors: SANTANA Lucas L.S. , MEDEIROS Carmen
Published: July 2020

Filtradores sésseis e bioacumuladores, as ostras são bons indicadores da saúde dos estuários. Alteração das características morfológicas de suas conchas e da relação peso de sua carne para o volume de sua concha, etc. refletem a qualidade do ambiente onde vivem. O presente trabalho enfoca uma avaliação das condições da ostra-de-mangue Crassostrea rhizophorae no estuário do rio Ipojuca, um dos mais poluídos do país. Para tanto 80 indivíduos de 4 áreas do estuário foram coletados em jan/2019 (pós-desova) e out/2019 (desova), pesados e mensurados. Com base nesses dados foram calculados os índices de espessamento da concha (STI1) e o índice de qualidade da norma francesa AFNOR. Resultados revelaram por um lado, a ocorrência de ostras comercialmente classificáveis como “finas” e mesmo “especiais” em termos de seu desenvolvimento e preenchimento do espaço intervalvar das mesmas. Por outro lado, baixos valores (< 4) do índice de monitoramento STI1, forte indicador de contaminação por TBTF, alerta para a necessidade de futuras investigações para confirmar essas suspeitas bem como para investigar a adequabilidade ou não das ostras do Ipojuca ao consumo humano.Palavras-Chave: ostra-de-mangue, Crassostrea rhizophorae, biometria, índices de condição.
