    Notes: Abstract  "Quality management is not just a strategy. It must be a new style of working, even a new style of thinking. A dedication to quality and excellence is more than good business. It is a way of life, giving something back to society, offering your best to others" (George Bush 1991). From this statement it becomes immediately clear that the human factor plays an eminent role in quality management. Therefore, some important relevant aspects of quality management are highlighted which are not so frequently discussed elsewhere. Various definitions and statements on quality lead to the fact that quality depends essentially on people. Some thoughts are developed on the Japanese quality culture which contributed essential impulses to the evolution of certain quality installations such as quality circles. The Japanese also developed a philosophy of quality, Kaizen, which is significantly different from Western industrial quality concepts. Kaizen works well in a slow growth economy, contrary to Western innovation which is more suited to the fast growth economy of the past. Some ideas on the quality control of top management as well as on the quality control of ourselves are expressed and it is shown how this is related to ethical principles. Every human society is as successful as: its intrinsic degree of honesty and righteousness, its degree of prevention of corruption and nepotism, and its readiness to work hard for personal advancement and for the sake of the community. Leadership, political or economic, is a special cultural effort – or at least it should be. But the striving for quality must be everybody's business in a company. It is the old 'pride of workmanship' which is greatly lost in today's industrial structures, and which is so absolutely important to again find satisfaction and contentment in our work. It is shown that the human factor in quality management, apart from all the necessary formal and institutional regulations, is of major importance, but very often neglected, especially in the present situation of over-rationalization. It is shown that dynamic equilibria do not only regulate chemical and biological systems but also operate in our psychic world. Unfortunately, there is a tendency to unhealthy extremes in the latter, e.g. to workaholics or neo-capitalism. Installations of total quality management such as systems, procedural and product audits are important facets of modern quality assurance. They are again closely related to human behaviour, as well as the procedure of company and laboratory accreditation. Finally the "Codex Hammurabi" shows that product liability was a clearly regulated issue in ancient Babylon, 2200 BC. This may be indicative of the fact that many new trends propagated by management gurus usually stem from a very old part of the wisdom of mankind but they are newly decorated and formed to modern slogans.

    Notes: The mechanisms of enhanced electron injection into the electron transport layer of Alq3 [tris(8-hydroxyquinoline)-aluminum] via LiF interlayers are studied by means of I–V characteristics, secondary ion mass spectroscopy (SIMS), and Kelvin probe measurements. Devices for single carrier injection were prepared using aluminum electrodes, Alq3 electron transport layers, and thin intermediate layers of LiF. It was found that devices deposited in the order Alq3-LiF-aluminum have a much higher electron injection capability than structures deposited in the order aluminum-LiF-Alq3. SIMS depth profile analysis reveals that the evaporation of Al on LiF leads to a spatial separation of Li and F probably induced by a chemical reaction of Al with LiF. Simple thermodynamic calculations support the energetic feasibility of such a reaction. Titanium cathodes in the same layer sequence also exhibit electron injection enhancement, probably due to their similar chemical reactivity. However, electron injection from Ag electrodes is not significantly improved by the introduction of a LiF interlayer. © 2001 American Institute of Physics.

    Notes: Abstract The oxidation behavior in air of two ODSsuperalloys, the chromia-forming PM 1000 and thealumina-forming PM 2000, was investigated attemperatures between 900 and 1300°C. For both alloysgrowth rates of the oxide scales obey a subparabolic timedependence and an Arrhenius-type temperature dependenceof the rate constants is observed. Diffusion of yttriumto the surface of the oxide scales leads to almost complete depletion of this element within theoxide scales of both alloys. Scale growth then takesplace by simultaneous inward diffusion of oxygen andoutward diffusion of cations. At this stage of the oxidation process, the scale-growth mechanismis similar for both ODS alloys, at least in aqualitative way, to conventional (non-ODS) alloys of thesame base composition.

    Notes: Abstract In the Eastern Alps compression during orogeny in the Upper Cretaceous caused crustal thickening, isostatic uplift and gravitational adjustment of the unstable orogenic wedge. This process triggered extensional basin formation on the back of the orogen (Gosau Basins). The basin fill of the Muttekopf Gosau Basin is arranged in megacycles, the first one comprising alluvial fan sediments and “Inoceramus marls” of the Lower Gosau Complex (Faupl et al. 1987) of Santonian age. Three other cycles follow (Upper Gosau Complex, Campanian to Maastrichtian), consisting of turbiditic fining upward sequences, that are indicative for extensional tectonics during basin formation, as subsidence events prevent formation of autocyclic coarsening upward sequences and therefore prograding of the turbidite system. Deposition of the 1st and 2nd Megacycle occured below the CCD (Carbonate Compensation Depth). The carbonate rich 3rd Megacycle was deposited probably below the CCD after a period of palaeogeographic reorganisation (uplift?) in the source area.

    Notes: Abstract  Seven rain and 2 snow samples collected in October and November 1993 were analyzed by GFAAS. Manganese concentrations ranging from 0.3 to 11.3 μg/L were found. pH-values (4.04–4.89, mean 4.52) and redox potentials (528–665 mV, mean 581 mV) were additionally determined. This is important with respect to a qualified specification of Mn in atmospheric samples. A 0.45 μm-filtration of the samples prior to GFAAS-analysis showed the same manganese concentrations in the filtrate as in the unfiltered samples. Hence, the amount of solid Mn species in the investigated samples is negligible. For an examination of the oxidation state of Mn some investigations concerning the stability of Mn(III) were carried out. They indicated that Mn(III) is unstable under atmospheric conditions. For checking whether all the manganese in rainwater exists as Mn(II), a sensitive IC method for the detection of Mn(II) was developed. By adapting a photometric procedure based on the oxidation of Leucomalachite Green (LMG) to Malachite Green (MG) by permanganate (MnO- 4) to the IC-flow-through-system, a limit of determination of 1 μg/L Mn(II) could be achieved. A comparison of the IC measurements with GFAAS-results of the filtered samples showed agreeing results. Thus, manganese in rainwater and snow exists entirely as soluble Mn(II).
