Collins, M.E., Manchester, S.R. & Wilde, W. 2012. Fossil fruits and seeds of the Middle Eocene Messel biota, Germany.Abhandlungen der Senckenberg Gessellschaft für Naturforschung, 570, 251 pp. ISBN 978-3-510-61400-4 This book presents a survey of the extensive fruit and seed collection found at the Middle Eocene Messel site. The first part of the book is dedicated to a few introductory chapters about the site, geologic setting, age control of the sedimentary sequence and taphonomy of the fossil remains. It is worth pointing out that unlike many lacustrine deposits in which fruits are preserved as impressions, most of the Messel plant macrofossils are preserved as remnants of the original pl…
Milano Parco Sud: L'Energia della Memoria
2007
Un'idea semplice e rivoluzionaria: riuscire a trasformare, in armonia con la tradizione, il “parco agricolo sud” di Milano. La proposta si sviluppa su più piani: restauro delle abitazioni e cascine del parco, lo fruttamento delle energie eco-compatibili (biomassa, energia solare e energia idraulica), e promozione del parco come meta turistica. Un lavoro simile è già in atto in diverse parti della regione Lombardia. L’area del parco del Ticino dopo due anni di lavoro è quasi tutta eco compatibile. Nella provincia di Cremona alcune aziende agricole hanno già iniziato a sviluppare e a monetizzare la biomassa.
OLD WORLD NEOGENE PRIMATES: DISCUSSION OVER AN UPDATED DATABASE

THE SIGNS OF WATER
2020
Signs of Water. A hidden waterscape in Palermo is recovered from the oblivion through a process consisting in a territorial analysis, a careful reading of ancient maps and historical archives, a deep design of new landscapes trancing the signs of the passage of water in a land where water has a permanent role along the centuries. A vast agricultural territory covers the Conca d'Oro valley, where lays the city of Palermo: rich in landscape, environmental and archaeological heritage, only some areas were subtracted from the intense construction and speculative activity that characterized the history of the city in the sixties and the seventies of the twentieth century. The main goal of this s…
The emission saving related to the use of renewable energy sources: The case study of solar thermal collectors
2003
The employment of renewable energy sources can represent a useful way to reduce air emissions released by conventional ones. In this paper we describe the results of a Life Cycle Analysis performed upon one of the most world-wide diffused renewable technologies: the solar thermal collectors for warm sanitary water. Two domestic solar plants have been investigated: mono-familiar plant with a passive flat collector and a large solar plant with forced fluid circulation. The first step has been the evaluation of direct and indirect emissions related to the production and use of plants. The main emissions have been categorised in three of the most important indicators (Global Warming Potential, …
LCA of a solar heating and cooling system equipped with a small water–ammonia absorption chiller
2012
The development of renewable energy technologies is a critical tool for reducing climate change and the reliance on fossil fuels. However, renewable energy technologies cannot be considered totally clean because they require energy consumption and have environmental impacts that cannot be neglected during their life cycle. In this paper, the life cycle assessment methodology was applied to assess resource use and other environmental burdens related to the entire life-cycle steps of a solar cooling plant. The investigated system works with an absorption chiller assisted by a solar plant. Two back-up configurations (hot back-up and cold back-up) were examined in two localities: Palermo (south…
Introduction of Offshore Wave, Wind and Solar Energies in Vietnam
2020
In Vietnam, the energy demand shows an ever-increasing trend. To limit the utilization of fossil fuels and the following consequences for the environment, renewable energy sources must be adopted. In this context, the paper assesses the utilization of offshore wind and sea wave, by considering a commercial wind turbine and a prototypical wave energy converter. Solar energy can be optionally also collected by this device. An algorithm is introduced to find the best composition of the three sources able to cover a desired share of energy demand. The approach is applied to Ca Mau, a province in the southern part of Vietnam. Finally, the results encourage the adoption of these energy sources th…
Formation of high added value chemicals by photocatalytic treatment of biomass
2020
The depletion of fossil fuel requires the search for alternative renewable feedstock and environmentally friendly methods for the production of high value-added compounds and fuels. In this context, the efficient use of biomass has emerged as a significant research field as it represents an alternative green and renewable carbon source. Various technologies have been explored for this purpose and heterogeneous photocatalysis represents a valid alternative to the catalytic methods since it can be carried out under mild experimental conditions without the addition of harmful oxidizing agents. Different biomass components have been used as the starting materials, and many valuable chemicals h…
Stato, rivoluzione e violenza simbolica. Una lettura à la Bourdieu dell’insorgenza cilena
2023
The essay is part of a book that aims to rediscover and enhance Pierre Bourdieu's contribution to the legal philosophy. Clelia Bartoli's paper takes up the French sociologist's theory of the State outlined during courses held at the College de France in 1989/1990 and 1990/1992. Bourdieu eschewed an intellectual fashion of his time that pushed historians, political scientists, lawyers and sociologists to examine the causes and reasons, evolutions and epilogues of revolutions, at the expense, however, of what is happening on the background: the dull, muffled and repetitive order of things. Bourdieu believed that permanence more than change, what is obvious more than what is eccentric, the ord…
