Acoustic characterization of the ancient theatre at Syracuse
2008
The ancient theatre at Syracuse, the largest open air theatre in Sicily, experienced many structural changes along its history. Today its very renowned drama festival attracts visitors from all the world that fill the entire cavea: customized seats accomodation and a prominent stage play an important role in the theatre acoustics. Because no data were available in literature on its acoustical perfomance a measurement session was carried out by our team in the framework of a wide research project on ancient theatres acoustics in the modern use. From data recorded "room criteria" parameters have been evaluated together with spectral analysis in order to gain a deeper information on the acoust…
Surface passivation of gallium selenide by nitrogen implantation
2002
In this paper we report on the characterization of nitrogen-implanted single-crystal GaSe samples. Nitrogen atoms were implanted at 80 keV, with doses ranging from 4 × 10 13 to 10 15 N + ions cm -2 . Next, samples were aged in open air and characterized by small-area XPS, together with an unimplanted clean surface, in order to quantify the effects of the nitrogen implantation. In general, we found that the oxidation was fully prevented in N + -implanted samples.
A view of the vegetation and economic exploitation of the forest in the Late Neolithic sites of Les Jovades and Niuet (Alicante, Spain)
1992
SummaryThe results of the charcoal analysis obtained in two open air sites of the Late Neolithic, although contrasting with what is known so far about their economy, as well as with the results of different palaeoamblental studies undertaken in other sites, mainly caves with long sequences, within the same area or in other near areas, form the main interest of this paper. We will begin presenting the data pertaining to both sites individually which, in the final part, will be assessed in order to reach a better understanding of the relationship between men and their natural environment during the Neolithic period.
Open-air Conservation of Ruins and the Concept of “Non-Dislocation”
2012
Most of the on-going debate is about “how” to protect archaeological ruins, whilst at the same time allowing the general public to enjoy them. Today it is clear how important it is, from the actual planning stages of excavations, to interact with experts from other disciplines, who are working on their own findings and offering them up for collective enjoyment. Whatever might be feasible for an indoor museum is not always feasible with an architectonic ruin, as regards both presenting objects with explicative apparatus that determines their significance, and exploring them in a new way when interpretations change or new ideologies are introduced. First of all, conserving excavations is the …
The public and private use of space in Magdalenian societies: Evidence from Oelknitz 3, LOP (Thuringia, Germany)
2015
Abstract The site of Oelknitz (Thuringia, Germany) is among the largest and in terms of spatial organisation most complex Magdalenian open air sites known to date, rich in evident structures. The current paper reports evidence from the youngest, latest phase of occupation at Oelknitz Structure 3. It is demonstrated that this structure represents a dwelling construction characterised by different spatially distinct activity zones. Several hypotheses can be drawn from this evidence in order to understand basic principles on Magdalenians’ settlement behaviour and their social cohesion.
Barbegal carbonate imprints give a voice to the first industrial complex of Europe
2019
International audience; The watermill complex of Barbegal is one of the first industrial complexes in the world, and one of the largest such installations known from antiquity. It has been studied through excavations and what is known about the complex, its history and purpose, is based on the remaining stonework of mills and water installations, since no traces of the woodwork or machinery of the mills have been preserved. The archaeological museum in Arles, however, stores 142 pieces of carbonate that formed on the woodwork of the mills. We studied this material by analysis of the shape of the fragments and of stable isotopes and crystallographic fabric of selected carbonate samples. This…
Occupational hygiene in biowaste composting
1998
Source-separated biowastes from the Helsinki Metropolitan Area have been composted in open air windrows at Ammas suo, the Helsinki regional landfill in Espoo (Finland). The most significant problem encountered in the early stages of the process has been the formation of rancid odor causing human discomfort. The offensive odor was mainly due to car boxylic acids. A total of 110 organic compounds were detected in volatile emissions from windrow composts with an integrated sensory and instrumental method. Occasionally the temperatures in the windrows exceeded 80°C. Bacterial measurements also revealed substantial populations of bacte ria at 75°C. The concentrations of airborne microbes and en…
Investigation on phospheonol pyruvate carboxylase and proline in damaged and indamaged needles of Picea Abies and Abies Alba
1998
The client of forest damage is rapidly characterized by visible criteria such as loss and yellowing of leaves and needles Additionally damage to Norway spruce (Picea abies) and silver fit (Abies alba) can be diagnosed by biochemical criteria. The results in the present study performed in 1993 and 1994 on six Norway Spruces of each of the eleven open air stands in south-western Germany indicate that the activity of phosphoenol pyruvate carboxylase (PEPC) correlates with the extent of damage and of the loss of needles, respectively. Needles of severely damaged trees had higher levels of PEPC than needles of healthy trees. There was also a positive correlation between the activity of PEPC and …
Dziedzictwo (po)górnicze - dylematy i perspektywy
2017
This paper discusses the process of transformation of the (coal) mining heritage from the 1990s up to the present day. It draws attention to the development of new trends related to the conservation and documentation of that heritage. In the last decades, numerous open air museums, tradition parks, monument trails have been created, which, through various forms of activities, encourage people to take interest in the history and traditions associated with mining. Today, the mining heritage has a significant potential, especially in terms of popular forms of tourism (industrial, urban, thematic). Due to institutional and financial support, also on the part of local environments, and a well-de…
Therapy in the open air: Introducing wilderness therapy to adolescent mental health services in Scandinavia
2015
Despite the rich traditions of outdoor life in the Scandinavian countries, structured nature-based therapeutic interventions remain underexplored in adolescent mental health services. We suggest that wilderness therapy is an age-appropriate and effective group treatment that may hold particular appeal for at-risk youth who are less responsive to conventional forms of treatment. Although more widespread in other parts of the world, wilderness therapy may also be a viable treatment modality for the Scandinavian region. Our overall aim of this state-of-knowledge article is to provide an overview of wilderness therapy with regard to conceptualization, practice and research, and to discuss curre…
