Diversidad como estrategia de proyecto en la transformación urbana
Authors: de Aragão C. Martins Anamaria 
Published: July 2020

El proceso de deslocalización de la segunda mitad del siglo xx y la reflexión
acerca de la utilización de nuevos mecanismos de planeamiento, proyecto
y gestión urbana en la ciudad consolidada crearon la oportunidad de intervenciones
de larga escala en las periferias industriales históricas. El proyecto
de transformación urbana responde a las especificidades de este territorio
entrecortado por obstáculos de diferente naturaleza y contaminado por
variadas preexistencias de su pasado industrial, creando nuevas actividades
y nuevas oportunidades para barrios periféricos. Basado en la tesis de
doctorado desarrollada sobre diferentes intervenciones urbanas, el presente
artículo estudia las estrategias de diversidad utilizadas en los proyectos de
transformación urbana en la definición de los trazados y en la composición
de los volúmenes edificados para evaluar el encaje del nuevo fragmento urbano
en su contexto.
The process of industry relocation of the second half of the twentieth century
and the reflection on the use of new mechanisms for planning, design and urban management in the consolidated city, created an opportunity to large scale
interventions in the historical industrial peripheries. The urban transformation
project responds to the specificity of this territory, interrupted by obstacles of different kinds and pre-existing conditions by its industrial past, and creating new
activities gives new opportunities for suburbs. The present article examines the
different strategies used, defining paths and the composition of the built volumes
in urban transformation projects to evaluate the fit the new urban fragment in
their context
Els edificis residencials a l’Eixample de Barcelona: tipus edificatori, desenvolupament residencial i habitatges tipus a l’Eixample
Authors: Castiñeira Palou Isabel , Peremiquel Lluch Francisco 
Published: July 2020

Sobre un patró homogeni d’illes i carrers es desenvolupa una gran varietat tipològica
i arquitectònica que respon als requeriments tipològics de l’habitatge,
però que està fortament condicionat per les característiques del suport: mides
i geometria de les illes, amples dels carrers, disposició de l’edificació i forma del
parcel·lari.
La capacitat d’adequació al pas del temps, a l’evolució dels requeriments socials,
als avenços tecnològics i del mercat immobiliari fan de la part edificada de
l’Eixample un conjunt paradigmàtic de les relacions habitatge-edifici-illa.
Les relacions mètriques i geomètriques tan en planta com de desenvolupament
vertical formen un conjunt de bones mides que caracteritzen el conjunt urbà de
l’Eixample.
On a homogeneous pattern of blocks and streets, it is developed a wide variety of
typologies and architecture to meets the requirements of housing, but is strongly influenced by the characteristics of the site: measurements and geometries of the block, street
width, construction layout and plot shapes.
The ability to adapt to social needs, technological advances and to real estate market
over the time makes the built part of the Eixample a paradigm of relationships between home-building-block.
Metric and geometric relationships, in both plan and vertical development, create a
good set of measurements that characterize the urban area of the Eixample.

Sembrando ciudades: la fundación de ciudades en la provincia de Buenos Aires (1810-1916)
Authors: Pesoa Marcilla Melisa 
Published: July 2020

A partir de la declaración de la Independencia en Argentina (1810-16), el
Estado debe enfrentarse a la problemática de un territorio vasto, desocupado
y poco productivo, cuyos recursos necesita movilizar para poder llevar a cabo
las reformas necesarias para construir una economía propia. Para ello se propone
la colonización del territorio de la Provincia de Buenos Aires mediante
la fundación de centros de población, lo que se lleva a cabo desde mediados
del siglo XIX hasta principios del XX.
La fundación sistemática de más de cien ciudades en un periodo de tiempo
tan acotado en una región central del país nos muestra un caso singular de
colonización que, puesto en contexto con las ideas y el cuerpo técnico que
posibilitaron su realización, nos permite hablar del nacimiento de un modelo
de ciudad auténticamente pampeana.
Since the Argentinian Independence (1810-16), the central government has to
face the problem of a vast, unoccupied and unproductive territory, essential to
start producing resources to generate incomes and carry out the reforms needed to
build its own economy. To face this situation, a huge colonization project of the
Province of Buenos Aires is proposed including the establishment of new cities.
This urbanization takes place from the mid-19th century to the beginning of the
20th century.
The systematic foundation of over a hundred cities in such a limited period of
time in the central region of the country shows a singular case of colonization,
which together with the ideas and the technical staff that made possible its realization, allows us to speak of the birth of a model of genuinely Pampa city

En este artículo se aborda el debate sobre la ordenación del litoral español. Los problemas y soluciones que se plantean en la ordenación de la costa ante la degradación producida por la ocupación urbana, industrial y turística de la misma. Para llevarlo a cabo se toma como referencia el debate que se ha producido entorno a este tema desde la ingeniería y el urbanismo en los últimos treinta años. Las Directrices de Ordenación del Litoral Canario se ponen como ejemplo de cómo se puede dar respuesta al problema de la ordenación del litoral desde el urbanismo y el medioambiente. El artículo se cierra con una re exión sobre la necesidad de implicar a la sociedad en el debate sobre la ordenación de la costa para preservar sus valores.
This article touches on the debate about the organization of the Spanish coast, the problems and solutions that arise in its management, responding to the degradation caused by urban, industrial and touristic occupancy. To discuss this, the debate that has occurred around this issue from the engineering and urban planning policies of the last thirty years has been analysed. e Canary Coastline Planning Guidelines are an example of how one can give an answer to the problem of coastal management from the planning and environmental perspective. e article closes with a re ection of the need to involve society in the debate about coastal management in order to preserve its values.
Il paesaggio del camping nella storia: dall’impatto zero alla colonizzazione intensiva
Authors: Lucivero Marilena 
Published: July 2020

Il campeggio è una tipologia ricettiva all’aria aperta che risponde all’esigenza di un rapporto di simbiosi tra il turista e la natura. Nasce come pratica spontanea priva di impatto sul paesaggio ma, con l’avvento del turismo di massa, si struttura in maniera più invasiva no a colonizzare grandi aree in maniera intensiva e irreversibile. L’articolo ricostruisce le tappe evolutive del campeggio come infrastruttura turistica dalla sua nascita (inizi XX secolo) ad oggi.
Camping is an open air type of accommodation that satisfies the requirement of a
symbiotic relationship between the tourist and nature. Born as a spontaneous practice
without impact on the landscape, it becomes more invasive with the advent of mass
tourism, colonizing large areas in an intensive and irreversible way. The paper
reconstructs the evolutionary phases of the campsite as a tourist infrastructure since its
inception (early twentieth century) to the present

Le Marais poitevin est l’une des plus grandes zones humides de France après la Camargue. Connu à l’échelle internationale pour l’accueil des oiseaux d’eau en migration et en hivernage, le Marais poitevin est aussi un site clé à l’échelle nationale pour la reproduction des limicoles. Depuis les années cinquante, le paysage du Marais poitevin a fortement évolué, plus de 47 % de la surface de prairies a été transformée en cultures céréalières. Cette étude fait le bilan des deux dernières enquêtes décennales sur la reproduction de huit limicoles du Marais poitevin 2005-2006 et 2015-2016. En dix ans, les effectifs nicheurs sont à la baisse pour le Vanneau huppé Vanellus vanellus (Linnaeus, 1758) (–9 %), le Chevalier gambette Tringa totanus (Linnaeus, 1758) (–30 %) et la Barge à queue noire Limosa limosa (Linnaeus, 1758) (–45 %). La création de plans d’eau associée aux réfections des digues suite à la tempête Xynthia (2010) a consolidé et favorisé les populations d’Avocette élégante Recurvirostra avosetta Linnaeus, 1758 (+89 %) et dans une moindre mesure celles d’Échasse blanche Himantopus himantopus (Linnaeus, 1758) (+10 %). L’analyse de l’influence des mesures agro-environnementales sur le territoire semble signaler une faible efficacité relative du premier et deuxième niveau pour l’accueil de la nidification d’une partie des espèces de limicoles nicheurs contrairement aux niveaux les plus contraignants, les plus environnementaux, incluant notamment le paramètre « maintien des niveaux d’eau au printemps ». Il est urgent pour l’avenir des limicoles reproducteurs du Marais poitevin que des mesures fortes soient instaurées par la mise en place d’une politique agricole « zone humide » volontaire, visant à maintenir et augmenter fortement les surfaces de prairies avec des niveaux d’eaux plus élevés au printemps.

Biogeographic and taxonomic knowledge on planktonic mollusks, specifically on Pterotracheoidea (also known as heteropods or sea elephants) in tropical oceans, is still incomplete. In this paper we report the first record of the heteropod Firoloida desmarestia Lesueur (1817) on waters off the Northeast Brazilian continental slope and Fernando de Noronha Archipelago and extend its geographic distribution in the tropical Atlantic. We provide new detailed digital image and descriptions of this highly fragile and transparent gelatinous species. Samples were taken in the context of the ‘ABRACOS’ (Acoustic along the Brazilian Coast) project using bongo nets. Out of 96 samples analyzed, six specimens were recorded in five samples, three at Fernando de Noronha, and three off the Northeast Brazilian coast. The present study extends the range of distribution of F. desmarestia to 3°S-9°Sin the western the Tropical Atlantic and highlights the importance of detailed studies on large-sized gelatinous plankton biodiversity in tropical oceans. Keywords: Tropical oceanic islands, Continental slope, zooplankton, heteropods, Pterotracheidae.

Published: July 2020

Background: Pulses are important food crops that can play a major role in achieving food security, nutrition, and human health, contributing to the sustainability of agriculture and aiding the mitigation and adaptation to climate change. The nutrient uptake is directly or indirectly affected by many factors like total concentration as well as available quantity of different nutrients, root development, aeration, water potential, climatic conditions and other related soil parameters.
Aims: A field experiment was carried out to find out the effects of different manures along with inorganic fertilizers on nutritional status of two mungbean varieties.
Study Design: Experimental treatments consisted of eight combinations of each manure and inorganic fertilizers with Soil Test Base (STB).
Results: The results showed that integrated effects were found significant on Ca, Zn and Mn contents in seed and P, Mg, Fe, Cu, Zn and Mn contents in stover. The highest N (4.34%), Mg (0.48%), P (0.56%) contents in seed and N (1.52%), Mg (0.78%) and B (30.67 µg g-1) contents in stover was obtained by the application of 3 t ha-1 poultry manure + 70% STB. The highest seed protein content was found from the same treatment. On the other hand, the highest Zn, Mn, Cu and S contents in seeds, and Zn, Fe and K contents in stover were obtained from 3 t ha-1 vermicompost + 70% STB. The treatment of 3 t ha-1 poultry manure + 70% STB produced the highest uptake of N, P, K, Ca, Mg, Zn, Mn, and Cu in seeds and the highest uptake of Mg, Fe and B was found with stover. The nutrient contents of seeds were positively and significantly correlated with each other. In Principal Component Analysis (PCA), the first two principal components accounted for approximately 81.80% of the total variability. BARI Mung-6 appeared as the best variety and poultry manure @ 3 t ha-1 along with 70% inorganic fertilizers treatment for the better nutritional quality of Mungbean.
Conclusion: It was observed that different treatments performed differently in respect of nutrients contents and uptake of seed and stover, and protein contents. From the above experimental findings, it is concluded that BARI Mung-6 appeared as the best variety and poultry manure @ 3 t ha-1 along with 70% IF should be applied for getting better nutritional mungbean seed with higher protein contents under the agroclimatic condition of BARI.

Contributing Factors for the Agricultural Graduates Converted as Successful Agri-preneurs
Authors: Gopal P. V. Sathya 
Published: July 2020

Agricultural education has now to evolve in tune with fast changing national and international scenario. The agricultural graduates are required to possess professional capabilities to deal with the concerns of sustainable development. Agri-business comprises of organizations and enterprises which in some way contribute for value and supply chain elements such as production, processing, marketing, packaging, transportation and wholesale and retail trade. Bringing as many agricultural graduates in the field of entrepreneurship as agri-preneurs is the challenging task of the policy makers in the present situation. Entrepreneurship in Agriculture is a strategic development intervention that has the potential to accelerate the development process. Agri-preneurship is greatly influenced mainly by the economic situation, education and culture. Integration of entrepreneurship education into the curriculum is imperative so as to produce graduates who would be self-employed in the face of biting economic quagmire where the government cannot provide employment for every graduate. A total of ten (10) agri-preneurs who are the alumni of State Agricultural Universities (SAUs) of Andhra Pradesh and Telangana states completed their under graduation or post graduation and converted as successful agri-preneurs in different agriculture and allied activities were selected as sample. Exploratory research design was adopted in the study to obtain pertinent and information of the respondents. The case study method used for the documentation of agriculture graduates as successful agri-preneurs. Semi-structured interview schedule was designed for data collection. The factors were broadly divided into three categories viz., personal factors, financial factors, and environmental factors. The respondents were asked to rank the factors for each category separately. By using the Garrett’s ranking technique, the important factors which lead to become successful agri-preneurs were determined. Among personal factors work experience, passion, Communication and Marketing Skills; among financial factors Capital, Financial Resource; among environmental factors Market Demand, Man Power were found to be more significant factors influencing the establishment and for further growth of business. Hence there is a need to orient the agricultural graduates towards those factors and inculcate such paradigms in their academic environment for converting agricultural graduates as successful agri-preneurs.
Structural insights into the enhanced carbapenemase efficiency of OXA‐655 compared to OXA‐10

Carbapenemases are the main cause of carbapenem resistance in Gram‐negative bacteria. How β‐lactamases with weak carbapenemase activity, such as the OXA‐10‐type class D β‐lactamases, contribute to anti‐bacterial drug resistance is unclear. OXA‐655 is a T26M and V117L OXA‐10 variant, recently identified from hospital wastewater. Despite exhibiting stronger carbapenemase activity towards ertapenem (ETP) and meropenem (MEM) in Escherichia coli, OXA‐655 exhibits reduced activity towards oxyimino‐substituted β‐lactams like ceftazidime. Here, we have solved crystal structures of OXA‐10 in complex with imipenem (IPM) and ETP, and OXA‐655 in complex with MEM in order to unravel the structure–function relationship and the impact of residue 117 in enzyme catalysis. The new crystal structures show that L117 is situated at a critical position with enhanced Van der Waals interactions to L155 in the omega loop. This restricts the movements of L155 and could explain the reduced ability for OXA‐655 to bind a bulky oxyimino group. The V117L replacement in OXA‐655 makes the active site S67 and the carboxylated K70 more water exposed. This could affect the supply of new deacylation water molecules required for hydrolysis and possibly the carboxylation rate of K70. But most importantly, L117 leaves more space for binding of the hydroxyethyl group in carbapenems. In summary, the crystal structures highlight the importance of residue 117 in OXA‐10 variants for carbapenemase activity. This study also illustrates the impact of a single amino acid substitution on the substrate profile of OXA‐10 and the evolutionary potential of new OXA‐10 variants.
Engineering Light‐Responsive Contractile Actomyosin Networks with DNA Nanotechnology

Published: July 2020

AbstractExternal control and precise manipulation is key for the bottom‐up engineering of complex synthetic cells. Minimal actomyosin networks have been reconstituted into synthetic cells; however, their light‐triggered symmetry breaking contraction has not yet been demonstrated. Here, light‐activated directional contractility of a minimal synthetic actomyosin network inside microfluidic cell‐sized compartments is engineered. Actin filaments, heavy‐meromyosin‐coated beads, and caged ATP are co‐encapsulated into water‐in‐oil droplets. ATP is released upon illumination, leading to a myosin‐generated force which results in a motion of the beads along the filaments and hence a contraction of the network. Symmetry breaking is achieved using DNA nanotechnology to establish a link between the network and the compartment periphery. It is demonstrated that the DNA‐linked actin filaments contract to one side of the compartment forming actin asters and quantify the dynamics of this process. This work exemplifies that an engineering approach to bottom‐up synthetic biology, combining biological and artificial elements, can circumvent challenges related to active multi‐component systems and thereby greatly enrich the complexity of synthetic cellular systems.
What Caging Force Cells Feel in 3D Hydrogels: A Rheological Perspective

Published: July 2020

AbstractIt has been established that the mechanical properties of hydrogels control the fate of (stem) cells. However, despite its importance, a one‐to‐one correspondence between gels' stiffness and cell behavior is still missing from literature. In this work, the viscoelastic properties of poly(ethylene‐glycol) (PEG)‐based hydrogels are investigated by means of rheological measurements performed at different length scales. The outcomes of this work reveal that PEG‐based hydrogels show significant stiffening when subjected to a compressional deformation, implying that conventional bulk rheology measurements may overestimate the stiffness of hydrogels by up to an order of magnitude. It is hypothesized that this apparent stiffening is caused by an induced “tensional state” of the gel network, due to the application of a compressional normal force during sample loading. Moreover, it is shown that the actual stiffness of the hydrogels is instead accurately determined by means of both passive‐video‐particle‐tracking (PVPT) microrheology and nanoindentation measurements, which are inherently performed at the cell's length scale and in absence of any externally applied force in the case of PVPT. These results underpin a methodology for measuring hydrogels' linear viscoelastic properties that are representative of the mechanical constraints perceived by cells in 3D hydrogel cultures.
