[EN] Extreme precipitation events that occurred between March 24 and March 26 of 2015 in the region of the Atacama Desert (26-29°S)
left around 30
victims, being one of the biggest events over the past 50
years, with total a cost of reconstruction of about 1.5
dollars. The mudflows which increased during the flashflood inundated much of the city of Copiapó and Tierra Amarilla. This manuscript
aims to model the mudflow of March 2015
in the Río Copiapó, specifically in the towns of Copiapó and Tierra Amarilla. The modeling
process is performed using the Rapid Mass Movement Simulation Model (RAMMS) that allows modeling...

[EN] Physically-Based groundwater Models (PBM), such MODFLOW, are used as groundwater resources evaluation tools supposing
that the produced differences (residuals or errors) are white noise. However, in the facts these numerical simulations usually show
not only random errors but also systematic errors. For this work it has been developed a numerical procedure to deal with PBM
systematic errors, studying its structure in order to model its behavior and correct the results by external and complementary means,
trough a framework called Complementary Correction Model (CCM). The application of CCM to PBM shows a decrease in local
biases, better distribution of errors...
[EN]The solution to water hammer in a water distribution system (WDS) is shown by applying three hybrid methods (HM) based on the
Box’s scheme, McCormack's method and Diffusive Scheme. Each HM formulation in conjunction with their relative advantages and
disadvantages are reviewed. The analyzed WDS has pipes with different lengths, diameters and wave speeds, being the Courant
number different in each pipe according to the adopted discretization. The HM results are compared with the results obtained by the
Method of Characteristics (MOC). In reviewing the numerical attenuation, second order schemes based on Box and McCormack are
more conservative from a...

[EN] In the analysis of river hydrodynamics a great quantity of variables are present, this variables when considered in solving the state
equations describe the flow behavior. In this work is presented the three-dimensional solution of the equations of Navier Stokes
averaged by Reynolds with a model of closing for the turbulence
; solution applied in the flow of the river Tercero or Ctalamochita
in the province of Córdoba, Argentina. The calculation tool for solving equations of state is the SSIIM model, a free software oriented
to the computational fluid dynamics developed at the Norwegian University of Science and Technology....
[EN] As Manuel de Solà-Morales noted, urbanity relies on the variety and quality of relations between things, materials and human beings. Considered as such, how are we to achieve an underground urbanity? This paper seeks to address this question through a focussed reading of a number of European urban projects from the 20th century; all of which put special care into ensuring the quality of their subterranean passageways. We begin with the carrefour à giration, which was designed by Eugène Hénard in 1906, in order to identify four fundamental attributes of this kind of urbanity: legibility, spatiality, accessibility and activity....
[EN] The Avant-Garde movements of the twentieth century explored the creative possibilities of new types of media in architecture, such as the photographic camera or cinema. In a series of experimental projects, authors such as El Lissitzky based their work on assimilating the human eye with a mechanical lens, making it possible to create new concepts of space. A simultaneous consideration of the resources of Vertov’s Cine-Eye in relation to the exhibition projects of El Lissitzky reveals some of his proposals as paradigmatic examples of the perceptive experimentation of the viewer in relation to art, and in a wider sense,...
[EN] The concept of “the ordinary” has become an ever more usual reference in the analysis of certain architectonic and territorial situations; but also social ones, which seem to escape any order set by planning. Nonetheless, the word still carries a rather ambiguous meaning, because not only the term is in itself polysemic, but also because it can have several interpretations, sometimes in a contradictory way, depending on the area of study, the time or the place in which it is used. This text addresses some of these apparent contradictions through a selection of visual expressions that emerge from the...

[EN] It is very common to understand the home of the masters of architecture as a manifesto of their respective architectures. Nevertheless, those houses are usually identified with single-family models, relegating collective examples. Only the apartment-atelier that Le Corbusier elevated in Porte Molitor (1930-33) is saved from this oblivion. However, there are at the same time two other examples of house-studio by two masters of the moment: Perret and Piacentini. Both are parallel in their vital dynamics and in their programs: The Roman house-studio of Piacentini in Lungotevere Tor di Nona (1929-31) and the Parisian building of Raynouard (1929-33), where...

[EN] Alvar Aalto´s career has certainly been a complex one and has been reported by official historiography to be divided into some more or less well-defined periods which correspond to unitary in time clusters of projects. Thus, Paimio has come to be for architecture the consolidation of the Modern Finnish Project at its apparently orthodox splendor. Aalto, from the very beginning, was attracted by the possibility of generating his own project message. This may be the reason why he found researching into the evocative power of opposite conciliation which allowed him to obtain efficient tools to service his project. The...

[EN] As was the case in not just a few of his contemporaries, Francisco Cabrero's modern advent is centred on his initial trip, in this case the one made to Italy in 1941. The historiography of Spanish architecture in general and the specific studies on the architect have shown the impact and the scope of this two-month trip on his later career. Fleeing the ruling academicism in Spain, Cabrero 'discovers' in Italy the rationalist and abstract expression of monumentality. Nevertheless, the access to a wide photographic reportage —unpublished up to now— accomplished by the architect during the trip, allows us...

[EN] The Space Between (Walther König, Cologne, 2016) is the third part of the trilogy about the work of Alison and Peter Smithson seen through their own eyes. It follows The Charged Void: Architecture (2001) and The Charged Void: Urbanism (2005) both published by Monacelli Press, New York. This long-awaited book by Walther König features the same layout and general design as the two previous volumes but has a personality all of its own. The Space Between includes more than forty writings spanning the Smithsons’ entire career and features a wealth of illustrations from their own archives. Just as the...

Tangent and Corner Vertices Detection (TCVD) is a method to detect corner vertices and tangent points in sketches using parametric cubic curves approximation, which is capable to detect corners with a high accuracy and a very low false positive rate, and also to detect tangent points far above other methods in literature. In this article, we present several improvements to TCVD method in order to establish mathematical conditions to detect corners and make the obtaining of curves independent from the scale, what increases the success ratio in transitions between lines and curves. The new conditions for obtaining corners use the...

A new approach is presented to form self-supported bimetallic nanosized solids with acid and redox catalytic properties. They are water-, air- and H-2-stable, and are able to activate demanding C-C and C-H reactions. A detailed mechanistic study on the formation of the Ag-Fe bimetallic system shows that a rapid redox-coupled sequence between Ag+, O-2 (air) and Fe2+ occurs, giving monodisperse Ag nanoparticles supported by O-bridged diatomic Fe3+ triflimides. The system can be expanded to Ag nanoparticles embedded within a matrix of Cu2+, Bi3+ and Yb3+ triflimide.

Tuberculosis, one of the oldest diseases affecting human beings, is still considered as a world public health problem by the World Health Organization. Therefore, there is a need for new and more powerful analytical methods for early illness diagnosis. With this idea in mind, the development of a High Fundamental Frequency (HFF) piezoelectric immunosensor for the sensitive detection of tuberculosis was undertaken. A 38 kDa protein secreted by Mycobacterium tuberculosis was first selected as the target biomarker. Then, specific monoclonal antibodies (MAbs) were obtained. Myc-31 MAb, which showed the highest affinity to the analyte, was employed to set up a...

Background and objective
Induction of labor (IOL) is a medical procedure used to initiate uterine contractions to achieve delivery. IOL entails medical risks and has a significant impact on both the mother's and newborn's well-being. The assistance provided by an automatic system to help distinguish patients that will achieve labor spontaneously from those that will need late-term IOL would help clinicians and mothers to take an informed decision about prolonging pregnancy. With this aim, we developed and evaluated predictive models using not only traditional obstetrical data but also electrophysiological parameters derived from the electrohysterogram (EHG).
EHG recordings were made on singleton term...
