The LAGUNA design study- towards giant liquid based underground detectors for neutrino physics and astrophysics and proton decay searches
The feasibility of a next generation neutrino observatory in Europe is being
considered within the LAGUNA design study. To accommodate giant neutrino
detectors and shield them from cosmic rays, a new very large underground
infrastructure is required. Seven potential candidate sites in different parts
of Europe and at several distances from CERN are being studied: Boulby (UK),
Canfranc (Spain), Fr\'ejus (France/Italy), Pyh\"asalmi (Finland),
Polkowice-Sieroszowice (Poland), Slanic (Romania) and Umbria (Italy). The
design study aims at the comprehensive and coordinated technical assessment of
each site, at a coherent cost estimation, and at a prioritization of the sites
within the summer 2010.Comment: 5 pages, contribution to the Workshop "European Strategy for Future

Policy-driven monitoring and evaluation : Does it support adaptive management of socio-ecological systems?
Inadequate Monitoring and Evaluation (M&E) is often thought to hinder adaptive management of socio-ecological systems. A key influence on environmental management practices are environmental policies: however, their consequences for M&E practices have not been well-examined.
We examine three policy areas - the Water Framework Directive, the Natura 2000 Directives, and the Agri-Environment Schemes of the Common Agricultural Policy - whose statutory requirements influence how the environment is managed and monitored across Europe. We use a comparative approach to examine what is monitored, how monitoring is carried out, and how results are used to update management, based on publicly available documentation across nine regional and national cases.
The requirements and guidelines of these policies have provided significant impetus for monitoring: however, we find this policy-driven M&E usually does not match the ideals of what is needed to inform adaptive management. There is a tendency to focus on understanding state and trends rather than tracking the effect of interventions; a focus on specific biotic and abiotic indicators at the expense of understanding system functions and processes, especially social components; and limited attention to how context affects systems, though this is sometimes considered via secondary data. The resulting data are sometimes publicly-accessible, but it is rarely clear if and how these influence decisions at any level, whether this be in the original policy itself or at the level of measures such as site management plans.
Adjustments to policy-driven M&E could better enable learning for adaptive management, by reconsidering what supports a balanced understanding of socio-ecological systems and decision-making. Useful strategies include making more use of secondary data, and more transparency in data-sharing and decision-making. Several countries and policy areas already offer useful examples. Such changes are essential given the influence of policy, and the urgency of enabling adaptive management to safeguard socio-ecological systems.
Highlights
• Policy strongly influences Monitoring & Evaluation (M&E) of socio-ecological systems.
• We examine M&E of 3 major European policies in 9 regional and national cases.
• Policy-driven M&E is imperfect versus ideals of M&E to support adaptive management.
• Attention needed to systems, social issues, sharing data, and sharing intended uses.
• Examples from across Europe and different policies offer ideas for improvement

STUDY OF SOME INSULATING OILS AGING BY THERMAL CYCLING
The By gravimetric measurements and
coupled thermal analysis techniques (DTG+TG+DTA)
the aging of different sorts of insulating oil was
studied by thermal cycling between -400C and 850C.
The experimental results showed that, during the
thermal cycling of the investigated mineral oils, their
composition changes due to the volatilization of the
volatile fractions (mass losses between 3.9% and
5.8%), unlike the investigated vegetable oil that
showed a mass increase of approx. 0.66%. It has also
been found that the mineral oils can be ensure a safe
operation, without significant changes up to a
maximum of 1000C, as long as investigating vegetable
oil can be used without degradation risk up to 2000C
GASSING OF THE ELECTRICAL INSULATING FLUIDS - A DETERMINANT FACTOR OF THE TRANSFORMERS SAFETY IN OPERATION
The influence on the quality of the electrical insulating fluids on the safety in operation of the transformers has been evaluated. After processing the comparative experimental data obtained by gas chromatography technique on 5 different sorts of electrical insulating fluids (a sort of vegetable oil with high oleic content and with addition of 0.5% antioxidant "functional model" - compared with two commercial sorts of mineral oil, 1 mainly vegetable commercial oil, 1 commercial synthetic ester), thermal aged in contact with electrical insulating paper and copper for electrical use, at 110 ± 3 °C for 1000 hours in closed vessels (limited access to atmospheric oxygen) it has been found that at the transformers filled with mineral oils, the risk of explosion and fire is approx. 10 times higher than those filled with synthetic or vegetal ester. It has also been found that the ageing of the insulation paper is approx. 15 times slower in the synthetic and natural ester than in the mineral oils normally used in transformers
A REVIEW ON COUNTER-ROTATING WIND TURBINES DEVELOPMENT
On a dynamic energy market
characterized by the constant energy demand
increase and economic as well as environmental
constraints, the study and development of efficient
conversion systems of wind’s energy has been
approached by a considerable number of researchers.
Given the modern economic and environmental
challenges regarding the energy production and
consumption, an advance in the research of
innovative or improved wind energy conversion
solutions has been registered. The objective of this
paper is to provide a comprehensive, but not
exhaustive overview of research achievements in
counter-rotating wind turbine systems development,
characterization and use. The review presents the
first theoretical results that led to the counterrotating
wind turbines development as well as the
related methods used for investigating their
performance. Valuable results have been found
within various studies, which are carried out for
different testing systems and conditions.
Furthermore, there is still need of extensive studies,
taking into account that the counter-rotating wind
turbines have to prove their reliability in real
operating conditions
