The article shows the mythical connection among poetry, design and company involved in the stay in Chile of Catalan architect Germán Rodríguez Arias, amidst an exile and reinvention environment in a new territory since 1939. His friendship with Pablo Neruda provides uniqueness to the furniture design developed during the forties in our country. Rodríguez Arias, predecessor of the design in Chile embodies a special sensitivity in the designs to establish links with his origin and the host site, as well as, a special interest for shapes and materials which have cultural stamp based on simplicity and functionality concepts. Armchair "Isla Negra" and Chair "Catalana", the latter marketed by Muebles Sur Company founded in 1944 by Christian and Claudio Aguadé Tarrago.

The drawing has legitimized itself as an artistic expression and has become popular thanks to the various expressions and dry techniques associated to its instrument among which the graphite pencil has been a referent due to its versatility, immediacy and low cost. The silverpoint, a dry technique prior to the graphite dates back to 1400 and consists in a silver stiletto capable of drawing on a suitable surface producing such expressive qualities that become unique by the softness and the meticulous level of details to be achieved. By means of a gradual process, in which each stroke, light but irreversible, makes the design visible as it subjects it to the aging process resulting from the rust caused by the passing of time. This reflexive-like work, done on a series of drawings and sketches using silverpoint technique, records spaces in Concepcion city in order not only to capture but also preserve these impressions raised from the everyday activities of a silent heritage for both the observer's eyes and those who record this. The origin of the technique, its potentialities and a work selection as a result of the research project are briefly contextualized.

When Lewis Mumford described Jane Jacobs' work as "home remedies to fight urban cancer" (Miller, 1986) he incarnated not only the learned professor's scholarly opinion, but also the mood of an entire generation of urban planners used to pursuit urban knowledge in the study of the previously built city regardless its proper or improper condition in contemporary situations. This archeological-like approach to urbanism has evolved, via Space Syntax, to turn into a highly sophisticated yet successful methodological corpus for the study of the city and the way we inhabit it. We refer to the urban thinking lineage that seeks urban knowledge in the city or previously built urban space as Lynch's lineage. Having said that, we claim there is another urban thinking lineage that, despite being equally differentiable, has remained in a methodological underdevelopment condition. This lineage does not start its pursuit of urban knowledge in the study of an urban space perception or built city but in the study of that spatial manifestation clearly different represented by human beings and the way they interact among each other. Thus, this lineage's purpose of study is the interaction of human beings in urban space. We refer to this urban thinking lineage as Jacobs' lineage. This paper introduces methodological rudiments innovative to their development and consolidation. Its central argument is consistent with essential Hillier's criticism to the atavistic historical tendency of urbanism to prescribe dogmatically. It is, simultaneously, consistent with Carlo Ratti's criticism to Hillier's work regarding the faith leap in Space Sytax's predictions based on the axial map.

This paper presents a partitioned modeling of internal and gravity fluid waves that interact with flexible structures. The governing interaction model consists of three completely partitioned entities: fluid model, structural model, and interface model that acts as an internal constraint on the fluid-structure interface boundary. Thus, the proposed partitioned multi-physics modeling can employ two completely modular fluid and structure software modules plus an interface solver, hence amenable to partitioned solution algorithms. The interface discretization can exploit the nonmatching interface algorithm previously developed via the method of localized Lagrange multipliers. Also noted is that the present fluid model can make use of widely available finite element software for standard Poisson-type problems. © 2009 Elsevier B.V.

The changes the territory and the landscape have been through after the tsunami on February 27, 2010 have been quite significant: some urban nucleuses were practically "wiped out" by the hydrodynamic power of the water, others managed to survive because of various geographical accidents or construction-related factors. Leaving those places based in the Chilean coast and which are under a clear risk of tsunami results in an unthinkable possibility given that many cities in the country are built on the coastal region and their social economic development is articulated by their marine context. Nevertheless, 50 years have passed since the 1960 Valdivia earthquake and tsunami took place- the most powerful ever recorded rating 9.5 in Richter magnitude scale- to carry out a regular soil type use assessment on the basis of earthquake risk. Even though government policies have not resulted to be very effective to face one of the most destructive natural disasters, it is of paramount importance to assure the human capital, build mitigation barriers, set up resilient communities, implement education programmes and evacuation plans as well as suggest platforms of future development. The aforementioned, all together, constitutes some of the main premises to assure quality life in a wide part of our country. This approach will undoubtedly change the way the coastline is inhabited and generate new perceptions and suggestions for a society still living a post-disaster mourning to be significantly integrated from the reconstruction process to a comprehensive recuperation in which social capital will continue to be the leading participant.

This article explains the results of more than three years working in collaborative engineering learning development, at the master's degree level, in the school of industrial engineers of the UNED, distance university of Spain. The fundamental approach is based on the "distance methodology" and "continuous evaluation" of the students' work and periodic reviews. The need for a teamwork aptitude is assumed an implicit requirement and, therefore, there is a specific methodology for the project. The work is supported by data and statistics that show better results than those obtained in other subjects of the same master's where the teamwork option is not applied, or in other master's and degree subjects in the engineering field or other technical areas. The result is success in the response and participation of the students and a new methodology that could be transferred to other subjects that do not have a specific teamwork requirement, but could use this methodology to improve the results. © 2015 TEMPUS Publications.

Traditional dwellings in the wooded hills and mountains in the vicinity of Mexico City are wooden cabins with very little thermal insulation. A modest change in the internal roof construction was trialed in order to improve thermal comfort. Modelling showed a modest improvement in thermal comfort could be expected. The experimental cabin was used as a show house and community members were invited to stay overnight and subsequently surveyed to obtain their appreciation of the experience. Community surveys to find out attitudes to environmental issues were also carried out and the potential acceptance of the improved cabin design. © 2014 Elsevier Ltd.

This work covers the developmental rise and fall period. It ranges from 1939, the year of the earthquake and propagation of modern movement in the south of the country, and 1973, when the political crash finished off the housing strategies of the democratic State. The area, strategic for domestic production, allowed numerous projects under the charge of a variety of entities: some, agencies of the State; others, belonging to the regional industry. All of them involved basic essentials corresponding to a collective and contemporary form of housing. Its features indicate the appropriation of the rationalist vicissitudes. They reveal the modernization of popular domain cloaked by the functional and political utopia of the developmental environment that made up part of the urban image of this land. The leaving of this mark had nuances of decisions taken locally, the physical, geographical and territorial surroundings, all actors that imposed determining facts on the construction of the projects. Three factors: the State and its social welfare inspiration, the industrialists and their impulse to be a Good-Samaritan, and the architectural factors with their mission to modernize, all bring together form, the people and the land. This interconnection sustains the identifying relationship of local modernity.

Lean principles and methods have been successfully applied to precast concrete job shops and batch flows. The conversion of processes from batch flow environments to line flow environments is the main reason for the productivity gains that have been reported in the literature. By means of an action-research approach rooted in the philosophy of lean thinking, the authors show that further productivity gains are possible for precast concrete fabrication processes already running in line flow. This study took place at a company that had previously implemented lean measures, such as value stream mapping (VSM), workplace organization (5S Method), pull systems, and total productive maintenance (TPM). This earlier initiative provided productivity gains, although in a variable and unsustained way. The research approach could devise a simple stability process with a focus on method and manpower. After a series of improvement cycles, the production process achieved almost complete stability and obtained an additional productivity gain of 24%. These results suggest that neglecting stability issues in lean implementations means wasting part of the potential gains, in addition to risking the loss of previously obtained gains, even in environments apparently optimized for line flow. © 2013 American Society of Civil Engineers.

The early twentieth century saw the rise of vacation camps for frail children as educational and health-giving experiences provided by medical and philanthropic organizations. This article analyzes some of these early experiences, seen here as the predecessors of social tourism, in the Province of Buenos Aires. A combination of written sources are examined, mainly institutional reports, periodicals such as the Monitor de la Educacin Comn - published by the Consejo Nacional de Educacin (National Board of Education) - or laws, with photographs and plans for different examples. I argue that these buildings were both physical and cultural brands in the places where they were located, and that their architectural structure encapsulated ideas about leisure space and cures in unique natural environments.
