    Trabajo de investigaciónLos lineamientos básicos presentados, se basan en la clasificación de suelos MCT desarrollada en Brasil, específicamente para suelos tropicales, no se basa en las propiedades índices (límites de Atterberg, distribución granulométrica) como lo hacen las clasificaciones tradicionales, se basa en ensayos de laboratorio de compactación, pérdida de masa por inmersión en agua, de cuerpos de prueba compactados de dimensiones reducidas.Caracterización física y clasificación de los suelos tropicalesINTRODUCCIÓN 1.

    Water Law, Mining and Hydro-Energy Conflicts in South America: Tales from the Andes and Patagonia

    Get PDF
    Conflicts in connection with hydro-energy and mining activities vis-à-vis other water uses, mainly human consumption, agriculture, industry, tourism, or even the essential flows needed for ecosystem protection, call into question whether South America’s path in the 21st Century will be characterized as ‘open veins’ (borrowing from the title of Uruguayan writer Eduardo Galeano’s book) or sustainable development. In this era of ‘New Conquistadors’, as some have called it, the key question is whether water law and environmental legal frameworks in the region are fit to deal with the pressure posed by these extracting industries. The paper seeks to contribute to this debate by discussing legal issues in connection with a controversial gold mining project in the Argentina-Chile border and a hydro-energy project in the Chilean Patagonia. The goal of the paper is to provide a South American perspective of water law through the lens of conflict. The paper concludes that water-related conflicts in these projects reveal weaknesses in the regulatory scheme for such endeavours and underscores the need to adopt reforms or implement mechanisms to ensure that water resources are adequately assessed, protected, and monitored

    German crowd-investing platforms: Literature review and survey

    Get PDF
    This article presents a comprehensive overview of the current German crowd-investing market drawing on a data-set of 31 crowd-investing platforms including the analysis of 265 completed projects. While crowd-investing market still only represents a niche in the German venture capital market, there is potential for an increase in both market volume and in average project investment. The market share is distributed among a few crowd-investing platforms with high entry barriers for new platforms although platforms that specialise in certain sectors have managed to successfully enter the market. German crowd-investing platforms are found to promote mainly internet-based enterprises (36%) followed by projects in real estate (24%) and green projects (19%), with the median money raised 100,000 euro

    A Multicultural Experience Boosted by Specialized European Master: A Real Approach to Internatioanl Project Management

    Get PDF
    When the Specialized Master in International Project Management started in Madrid in 2009, ESCP Europe, a high-level school of management with international scope, decided to reinforce the European institution and also to foster innovation sustaining a wide international partnership network. Students and executives came from around the world and the school offered them a model of Project Management which prepared them for the multicultural future where geographically dispersed projects teams must collaborate with a common goal. Created in 1988, this Master keeps evolving and is a truly international program with international students and a real methodological revolution in Project Management education including international seminaries and destinations in emerging countries: Either, India and China, or Brazil and Argentina. This Specialized Master makes significant use of inductive teaching methods and interactive activities (project simulations, case studies, business plan development, etc.). This guarantees the skills acquisition needed to work in multidisciplinary, international and multicultural teams. The teaching methods emphasize experimentation and simulation exercises including International Consultancy Projects which requests an intensive use of Information and Communications Technologies in order to enable the international experience

    Personal aircraft: a more affordable luxury

    Get PDF
    Access to luxury products has been limited traditionally to the upper classes. Products and services related to the means of transport have usually been considered of luxury and industrialization has made accessible to much of the population in developed countries. An emerging market is personal aircraft which is currently restricted to certain layers of society but it is expected that their use will represent the next great advance in transport. This article has the object of presenting the results of ongoing research and it focuses on possible demand and the tendency to use this transport option in Spanish societ

    Fiber-wireless links supporting high-capacity W-band channels

    Seamless convergence of fiber-optic and the wireless networks is of great interest for enabling transparent delivery of broadband services to users in different locations, including both metropolitan and rural areas. Current demand of bandwidth by end-users, especially using mobile devices, is seeding the need to use bands located at the millimeter-wave region (30-300 GHz), mainly because of its inherent broadband nature. In our lab, we have conducted extensive research on high-speed photonic-wireless links in the V-band (50-75GHz) and the W-band (75-110GHz). In this paper, we will present our latest findings and experimental results on the W-band, specifically on its 81-86GHz sub-band. These include photonic generation of millimeter-wave carriers and transmission performance of broadband signals on different types of fibers and span lengths.
