The radicals OH and HO2 (also named HOx) play an important role in the chemical degradation and transformation of most trace gases in the troposphere. The rate of these processes depends strongly on the magnitude of the radical concentrations. Due to their high reactivity, their concentrations are very low (sub pptv and pptv range) and exhibit a strong regional variability. Therefore exact measurement of HOx in different regions and at different altitudes in the troposphere are very important for the understanding and modelling of the self cleaning ability of the atmosphere.

ABSTRACT

EuroWordNet is a multilingual lexical database constructed in the wake of WordNet. The ontological structure of the language-dependent layers, analogous to individual WordNets, through the semantic space of the interlingual index and abstract framework of the top level ontologies are examined. The semantic nature of the interlingual lexicon is examined as it applies to Gruber’s principles for the design of ontologies. Benefits of EuroWordNet’s design are highlighted. ordNet was originally proposed by Miller (1990) in an experiment to test an implementation of a model of lexical organization. Up to this point, ontological databases had been particularly small. WordNet was intended as a test of ontology design on a scale far larger than any existing lexical database, progressively incorporating the English lexicon into a large semantic database. W

Identification of novel energy saving concepts which are being developed worldwide, evaluating their practicality and speeding up the time scale of getting them into the market place for end user implementation as swiftly as possible is the major aim of EMINENT project. The development and implementation of the first version of the software tool capable to analyse the potential impact of new, yet underdeveloped energy technologies (early stage technologies, ESTs) in different sectors of society over different countries enables the project partners to proceed to case study analysis. Though the work on the evaluation tool and the database including their internet versions continues, several promising case studies have already been analysed with use of the tool. It proves that third generation solar cells have highest efficiency and lowest costs. Several biomass processing technologies show high performance and wide range of applications. Geothermal energy applications using compact and enhanced heat exchangers are another innovative and promising field. Power recovery technology in Fluid Catalytic Cracking (FCC) being efficient in converting waste heat into electricity also shows very short payback period which makes it attractive to the industry.
