Naturwissenschaftliche Methoden zur Beurteilung von Gemälden und Graphik

Stylistic criteria are sometimes not sufficient in order to differentiate with certainty between copies or fakes and originals. Analyses of paints, supports and artistic technique may give an indication for the earliest possible date of a painting or a work of graphic arts. For example, supports made from oak, fir, spruce and beech can be dated by yearring analysis (dendrochronology). Exclusively methods on micro and ultramicro scale are suitable for the identification of various materials, i.e. microchemistry, emission spectrographic analysis, X-ray powder diffraction because only very tiny samples can be taken from the object.     

Assessing environmental performance by combining life cycle assessment, multi-criteria analysis and environmental performance indicators

We present a new analytical tool, called COMPLIMENT, which can be used to provide detailed information on the overall environmental impact of a business. COMPLIMENT integrates parts of tools such as life cycle assessment, multi-criteria analysis and environmental performance indicators. It avoids disadvantages and combines complementary aspects of these three tools. The methodology is based on environmental performance indicators, expanding the scope of data collection towards a life cycle approach and including a weighting and aggregation step. A case study on the Thai pulp industry illustrates the usefulness of COMPLIMENT.
