Geochronological and geochemical constraints on the genesis of Cu-Au skarn deposits of the Santa María de la Paz district (Sierra del Fraile, Mexico)
No full textCu-Au skarn deposits of the mining district of Santa María de La Paz are located in the Sierra del Fraile, in the northern part of San Luis Potosí, Mexico. Samples of four different intrusions and their related skarn deposits were taken underground, in order to obtain whole-rock and mineral geochemical data. U-Pb LA-ICP-MS zircon data indicate crystallization ages of ca. 37.6–35.0 Ma for skarn-related granitic and granodioritic stocks, which show dominant metaluminous to slightly peraluminous, high-K calc-alkaline compositions. These intrusions were emplaced in a post-Laramide continental arc setting under shallow conditions, as suggested by fast cooling inferred from K-Ar biotite ages of ca. 35–33 Ma. Skarn deposits were contemporaneous with emplacement and crystallization of stocks, as revealed by Re-Os molybdenite geochronological data of exoskarn rocks. Skarn rocks show a general depletion of LILE and REE and a slightly enrichment in HFSE in comparison with intrusive rocks. Pyroxene and garnet show dominant hedenbergite and andradite compositions, respectively. The association of hedenbergite, pyrite, chalcopyrite, native bismuth and pyrrhotite during skarn mineralization suggest reducing conditions, typical for Au but not for Cu skarns. Highest metal contents are concentrated in exoskarn rocks, including anomalies of Cu, Fe, Ni, Sn, Sb, Zn, W and Bi. Metal contents, ore minerals and environmental conditions of skarn rocks, together with whole-rock geochemical data of stocks and pyroxene-garnet compositions, reveal some singularities for the Sierra del Fraile deposits, as they exhibit characteristics of both Cu and Au skarn deposits but might be also compatible with Fe, W, and Zn skarns. Hence, skarn and associated vein deposits of the Sierra del Fraile might have a high potential not only for Cu-Au, but also for several base metals, as reported for comparable post-Laramide skarn and hydrothermal deposits of central and northern Mexico.Fil: Siegesmund, Siegfried.

Hans Frei: theology and method
No full textA continuación se abordan temas centrales de la teología elaborada por Hans Frei, autor poco conocido en el contexto regional latinoamericano. La presentación se encuentra delimitada a su pensamiento tardío, y muestra su concepción tanto de teología como de método teológico. También busca destacar la transformación de la reflexión de Frei, que vincula progresivamente un creciente interés por aspectos vitales y contextuales de las comunidades creyentes.This article introduces main topics of Hans Frei’s theology. This author is not well known in the Latin American regional context. This presentation is circumscribed to his late thought and it shows Frei’s understanding as much of theology as of theological method. It also seeks to highlight the transformation of Frei´s reflection when he connects this reflection to his growing interests for vital and contextual aspects of the believer communities
Reverse supply chains
No full textA Circular Economy Handbook for Business and Supply Chains is an easily digestible and comprehensive handbook that provides a clear guide to the circular economy, helping the reader create future-fit, sustainable strategies. Real examples across a range of market sectors help businesses, students and policymakers understand the theory and fast-developing practice of the circular economy. To help the reader generate ideas, A Circular Economy Handbook for Business and Supply Chains provides a holistic framework for the design and supply chain and supporting business models, and includes tools the reader can use to get started.
Whilst growing global consumption presents fantastic business opportunities, our current linear systems (take some materials, make a product, use it and then throw it away) are not fit for purpose. The circular economy unlocks this problem by decoupling resources from consumption. Engaged businesses are re-thinking product design, material choices, business models and supply chains. A Circular Economy Handbook for Business and Supply Chains is a must-read for anyone who wants to apply the circular economy today.

Frei Otto and the development of gridshells
No full textAbstractThe innovative architect, Frei Otto, developed the concept of gridshells which could be designed by a funicular modelling method and constructed from an equal mesh net of timber laths bent into the planned shape. In 1970 this technique was used to construct a 9000m2 curved roof structure from 5cm square timber laths. This paper summarises the design and engineering work that went into the construction of this remarkable building
Digital Tectonics as a Morphogenetic Process
No full textp. 938-948Tectonics is a seminal concept that defines the nature of the relationship between
architecture and its structural properties. The changing definition of the symbiotic
relationship between structural engineering and architectural design may be considered one of the formative influences on the conceptual evolution of tectonics in different historical periods. Recent developments in the field of morphogenesis, digital media, theories techniques and methods of digital design have contributed a new models of integration between structure, material and form in digital tectonics.
The objective of this paper is to propose and define tectonics as a model of morphogenetic process. The paper identifies and presents the manner in which theory and emerging concepts of morphogenesis as well as digital models of design are contributing to this new model. The paper first analyzes the historical evolution of tectonics as a concept and characterizes the emergence of theoretical framework reflected in concepts and terms related to morphogenesis.Oxman, R.

„Arbeit macht frei” – kilka uwag o genezie i podłożu ideowym hasła na podstawie książki Wolfganga Brücknera "Arbeit macht frei: Herkunft und Hintergrund der KZ –Devise"
No full textThe following paper is based primarly on the extensive study conducted by Wolfgang Brückner in his book Arbeit macht frei: Herkunft und Hintergrund der KZ –Devise. The article aims to present the origin, social context and ideological background of the motto “Arbeit macht frei” and other related texts placed above the entrances to some of the nazi concentration camps. The author raises the question, to what extent was the act of placing of such a motto in a KZ a mere sign of cynism or a conscious demonstration of ideological conviction of the SS-members, internalized in the process of bringing up and socialization in a specific environment
