Controlled Cytotoxicity of Plasma Treated Water Formulated By Open-air Hybrid Mode Discharge
2017
Plasma‐activated liquids (PAL) attract increasing interest with demonstrated biological effects. Plasma exposure in air produces stable aqueous reactive species which can serve as chemical diagnostics of PAL systems. Here, we tailor aqueous reactive species inside plasma‐activated water (PAW) through treating water with AC air spark and glow discharges in contact with water. Chemical probing demonstrated species specificity between two types of PAW. Spark discharge PAW contains urn:x-wiley:14381656:media:ppap201600207:ppap201600207-math-0006 and urn:x-wiley:14381656:media:ppap201600207:ppap201600207-math-0007, while urn:x-wiley:14381656:media:ppap201600207:ppap201600207-math-0008and urn:x-w…
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…
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…
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.
Peñón de la Zorra y Puntal de los Carniceros (Villena, Alicante): Revisión de dos conjuntos de yacimientos campaniformes en el corredor del Vinalopó
2002
En el presente artículo se revisa la información existente sobre dos yacimientos campaniformes del Alto Vinalopó –Peñón de la Zorra y Puntal de los Carniceros–. Su importancia dentro de la investigación en tierras levantinas los ha convertido en una referencia casi obligatoria desde su publicación por parte de J. M. Soler García. In this article is cheked information about two bell beaker sites from Vinalopo Valley –Peñón de la Zorra and Puntal de los Carniceros–. The importance of this archaeological sites of investigation concerning Levante areas have got that these places would be an obligatory reference since the publication by J.M. Soler Garcia.
Levels of Preservation for Cultural Heritage within an Open-air Museum

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 …
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.
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…
