    Notizen: . The products and pathways of glucose catabolism in the insect trypanosomatids Herpetomonas muscarum ingenoplastis and Herpetomonas muscarum muscarum have been studied with the aim of elucidating how both organisms are able to proliferate well under aerobic and anaerobic conditions. When incubated in medium containing glucose as the only exogenous carbon source, catabolism was found to be fermentative in both cases. Acetate was a major product of both organisms while H. m. ingenoplastis produced more ethanol and propionate and less succinate than H. m. muscarum. Ethanol production by H. m. ingenoplastis decreased both under anaerobic conditions and in the presence of elevated CO2 concentrations, whereas succinate and propionate release by this organism were greater in high CO2 and anoxia, respectively. Succinate production by H. m. muscarum was greatest under anaerobic conditions in elevated CO2 whereas propionate was only a minor product. The same four products were released during growth of the organisms in complex medium, but the relative proportions differed suggesting that other substrates were being used. Both organisms contained enzymes of the glycolytic and pentose phosphate pathways, but while all activities of the TCA cycle were present in H. m. muscarum. NAD-linked isocitrate dehydrogenase, α-ketoglutarate dehydrogenase, succinate CoA synthase and succinate dehydrogenase were not detected in H. m. ingenoplastis. Fumarate reductase activity was present in both organisms. The data presented suggest that CO2-fixation and reverse flux through the TCA cycle may be important factors that enable the organisms to undergo anaerobiosis.

    Notizen: Using a multiple layer optical waveguide system consisting of two vertically slab waveguides, classical Young's fringes may be obtained in the far-field diffraction plane. In agreement with the simple theory of diffraction interference the spacing of the far-field fringes is easily observed on mm to cm dimensions without further transformation of the output light. The simple methods of fabrication and means of optical coupling should provide a readily adaptable method for examining the principles of interferometry in an integrated optical format. The structure acts to transform polarized incident plane wave input light into separate slab modes of the device which emerge as two closely spaced and coherent sources at the output. The elements required for a classical Young's fringe demonstration are therefore all embodied in this approach. The basic concept can be applied to an optical method for sensing. In one example of this we demonstrate measurement of the phase difference induced between the upper and lower propagating modes in structures due to water vapor diffusion into the layers which are formed from hydrophilic polymers. The Young's fringe patterns exhibit a spatial intensity distribution which is sensitive to water vapor introduced over the surface of the structure. Differences in the effective index between the modes of the two waveguides during the diffusion of the vapor causes phase shifts which result in redistribution in the fringe pattern. The anticipated limit of detection of these devices is lower than 1 ppm for water vapor. © 1999 American Institute of Physics.

    Notizen: Purpose - To evaluate the chances of success for Auchan in Russia, and draw conclusions for retail internationalisation theory. Design/methodology/approach - Provides a comprehensive analysis of the Russian retail landscape and emerging patterns of consumption, especially in the capital Moscow. Findings - The success of Auchan's Russian venture will depend on the extent to which the retailer is able to leverage its three sources of competitive advantage in its domestic market, namely the hypermarket concept, the channel mix, and the environmental context. This in turn will be a function of its ability to exploit its retail marketing skills, distribution abilities, unique retail formula, strong retail brand, or a combination of these. Research limitations/implications - The paper is not built on empirical data, but is speculative. Originality/value - The paper's primary value lies in the call which it contains for a more eclectic conceptual framework underpinning retail internationalisation theory. Such a framework would reflect the importance of a firm's capital structure, and also pay greater attention to organisational dynamics. Attention to these issues would enable researchers to reflect more accurately the reality of the retail internationalisation process in emerging markets.

    Notizen: Purpose - The purpose of this paper is to assess the future development of the transport sector in Europe. Design/methodology/approach - Drawing on published sources of information and some expert views, the paper considers trends, drivers of change, possible scenarios and policy issues. Findings - Transport demand for passengers and goods has grown consistently in the past and is expected to continue to do so in the future. Existing policies are unlikely to modify this trend or alleviate existing problems. Research limitations/implicaions - The paper is based on existing sources. Practical implications - Decisions in a wide range of policy fields have implications for transport, which are seldom considered. Originality/value - Questions the sustainability of continuing growth in transport demand and the adequacy of current policy.

    Notizen: A 40-year-old female patient presented with a flat scar-like plaque on the upper chest. The patient’s perception of subtle change in the lesion was of paramount importance in the decision to biopsy this lesion of innocuous clinical appearance. Histopathological findings were those of dermatofibrosarcoma protuberans. This case illustrates the early clinical features of the tumour and a recommendation for taking a biopsy of any scar-like plaque where there is no clear history of preceding trauma.
