In situ studies on the physical and chemical properties of Au in inverse ceria alumina supported catalysts have been conducted between 295 and 623 K using high energy resolved fluorescence detection X-ray absorption near edge spectroscopy and X-ray total scattering. Precise structural information is extracted on the metallic Au phase present in a 0.85 wt% Au containing inverse ceria alumina catalyst (ceria/Au/alumina). Herein evidence for the formation of an Au hydride species at elevated temperature ...

Few aphids have been found as fossils in the Danish Eocene diatomaceous earth at the Limfjord in North-Jutland until now. There may be climatic reasons for their small number. From the knowledge of the fossil fauna of other insect groups in the Danish diatomaceous earth it has been deduced that the climate was tropical or nearly tropical in Denmark during Lower Eocene (Henriksen 1922). The number of aphid species in the tropical regions of the present day is rather small. Most species occur in the ...

Experimental melting studies were performed on a natural high-Al basalt and a synthetic average Archaean tholeiite (AAT) composition (0.3 wt.% K20) with variable amounts of H20. Microprobe analyses of quenched melts (glass) from mns at 5-30 kbar and 7501100°C showed that typical Archaean tonalitic and trondhjemitic compositions were produced from the average Archaean tholeiite over the entire experimental range, with 15% to less than 1% H20. The high-Al basalt produced liquids too high in A1203 (18- ...

The EU Water Framework Directive (WFD) includes new common standards for an integrated assessment of entire hydrological systems at the catchment scale, implying among others, that water ion may not affect dependent ecosystems such as wetlands, lakes and water courses, nor the water quality of existing drinking water resources. Methods are needed to ensure that these requirements are fulfilled. To this end we developed and tested a procedure based on the application of results from a regional groundwater ...

Borehole data and hydraulic heads are some of the most important data in groundwater modelling, and they are often treated as if they were 100% correct. They may not be, and the problems arising from that are often neglected or not fully recognized. The result may be that comprehensive and time consuming modelling is built on erroneous data which in the end may lead to uncertain or wrong conclusions. Therefore, it is important to recognize the errors attributed to both the primary borehole data ...

Qualitative statements regarding such objections were drawn from four national surveys and arranged into a paired- ...

The chemical compositions and crystal structures of Mn3+-containing minerals from the epidote group in Greenland rocks are investigated and described in detail. They occur in hydrothermally altered Archaean mafic sequences within the gneissic complex of the North Atlantic craton of West Greenland. The Mn-containing minerals have a characteristic red to pink colour. A detailed microchemical study shows a significant inter- and intra-sample variation in Mn content. The samples from different parageneses ...

This article analyzes a particular kind of harmonic practice which has become increasingly common in rock and pop music in recent years. This harmonic practice is termed “Aeolian harmony,” as it is based on chord progressions utilizing triads made up of notes from the Aeolian or “natural minor” scale. The origins of this type of harmony are discussed, and it is argued that it may have developed from chord root progressions based on segments of various pentatonic scales derived from blues and blues- ...

The driving force for gas migration is buoyancy, aided in some cases by sediment overpressure gradients (pressures above hydrostatic). Resistance to migration is controlled by the-capillary entry pressure into the pore network of the overlying sediments, or by their resistance to fracturing. It can be shown that migration mechanisms vary with depth. Below the upper few hundred metres gas migrates by invading the pore network of the sediment whereas at shallower depths fracturing may occur preferentially. ...
