Moscow doctor A.G. Dreytser – author of "The Notes of an Ambulance physician"
No full textWe have attempted to present the scientific biography of Alexander Grigorievich Dreytser, the author of "The Notes of an Ambulance physician" – a popular documentary work on the life of Moscow and Muscovites during the Great Patriotic War. We have reconstructed the main points of life and activities of A.G. Dreytser and discovered a number of facts in his biography related to his studying at Strasbourg University (1911–1914) and Imperial Moscow University (1915–1917), participation in the First World War and activities in 1918–1941. The analysis of the materials stored in the State Archive of the Russian Federation, the Central State Archive of the City of Moscow, the Russian State Archive of Literature and Art, as well as the personal archive of the Dreytser family, allowed us to clarify many points related to Dreytser's life and activities during the time prior to the creation of The Notes. This article is based upon the results of a comparative analysis of the texts of The Notes and A.G. Dreytser's Ph.D. dissertation "The Material on the Question of Sudden Death: According to the Data of Morgues, Moscow City Emergency Stations and the Department of Clinical Examination of the Central Polyclinic of the People's Commissariat for Health of the USSR". This article considers the hypothesis of the unity of the events that took place in Moscow during the Great Patriotic War and were described in the dissertation and The Notes. More complete historical and biographical data on A.G. Dreytser allowed us to prove the documentary nature of The Notes, expand the scope of known facts about the organisation of medicine during the war and clarify some circumstances of the history of Russian medicine as a whole
A model-based approach to correcting spectral irradiance data using an upward-looking airborne sensor (CASI ILS)
No full textA number of aircraft sensors have the facility to measure spectral downwelling irradiance using a sensor mounted on the roof of the aircraft, but these data are rarely used for atmospheric correction. Part of the problem is that the attitude of the airborne platform is always changing during flight, even in stable conditions, so that direct use of data from an incident light sensor (ILS) can introduce errors into atmospheric correction methods. The continual motion of the ILS is used here to advantage, as a means to fit a sky radiance distribution model developed by Brunger and Hooper (1993) to data from the Itres Instruments CASI ILS. The inclination of the ILS sensor, due to changing aircraft attitude, is considered as
the slope plane in the model. The selected model coefficients correspond to parameterised atmospheric conditions and represent atmospheric transmission and the proportion of direct:diffuse flux. The method was used to correct CASI ILS data acquired over a site in southern England. Comparison with spectral irradiance measured simultaneously on the ground shows that the method reduced the variability of the ILS data and also compensated for the effect of different flight directions. The sky radiance distribution at sensor level is also calculated by
the model, and shows the characteristics of the sky conditions at the time of each flight
Retrieval of at-sensor irradiance using Incident Light Sensor (ILS)
No full textA number of aircraft sensors have the facility to measure spectral downwelling irradiance using a sensor mounted on the roof of the aircraft, but these data are rarely used for atmospheric correction.

The continual motion of the ILS is used here to advantage, as a means to fit a sky radiance distribution model developed by Brunger and Hooper (1993) to data from the Itres Instruments CASI ILS. The inclination of the ILS sensor, due to changing aircraft attitude, is considered as the slope plane in the model. The selected model coefficients correspond to parameterised atmospheric conditions, i.e. clearness index and diffuse ratio. The ILS data corrected by the model are wellmatched
to variations of irradiance measured at ground level during three flights. The radiance distribution at sensor level is also calculated by the model, and shows the characteristics of the sky conditions at the time of each flight
Towards a budget approach to Pleistocene terraces: preliminary studies using the River Exe in South West England, UK
Full text linkThis paper presents a first approach to using a sediment budget methodology for paired terrace staircase sediments in SW England. Although a budget approach has become firmly established in Holocene fluvial studies, it has not been used in Pleistocene sequences due to the problems of temporal resolution, catchment changes and downstream loss from the system. However, this paper uses a budget approach in a paired non-glaciated basin, primarily as a method of interrogating the terrace record concerning the degree of reworking and new sediment input required to produce the reconstructed terrace sequences. In order to apply a budget approach a number of assumptions have to be made and these are justified in the paper. The results suggest that the Exe system can most parsimoniously be explained principally by the reworking of a Middle Pleistocene floodplain system with relatively little input of new resistant clasts required and a cascade-type model in geomorphological terms. Whilst this maybe partially a result of the specific geology of the catchment, it is likely to be representative of many Pleistocene terrace systems in NW Europe due to their litho-tectonic similarities. This cascade-type model of terrace formation has archaeological implications and sets the context for the Palaeolithic terrace record in the UK. Future work will involve the testing of this and similar budget models using a combination of landscape modelling and chronometric datin
A modified Rayleigh conjecture for static problems
No full textAbstractA modified Rayleigh conjecture (MRC) in scattering theory was proposed and justified by the author [A.G. Ramm, Modified Rayleigh conjecture and applications, J. Phys. A 35 (2002) L357–L361]. The MRC allows one to develop efficient numerical algorithms for solving boundary-value problems. It gives an error estimate for solutions. In this paper the MRC is formulated and proved for static problems
The influence of steady blowing and roughness on transitional separated boundary layers
No full textThis paper presents the results of a study between two types of forcing, namely steady blowing and a tripwire, on the control of laminar separated boundary layers. The analysis focuses on the differences in the transition process between these two types of forcing. This effect will be studied using direct numerical simulation. The main differences consists in the coherent structures formed during transition and the overall kinetic energy growth
Imaging of boron in altered mantle rocks illuminates progressive serpentinisation episodes
No full textSerpentinised mantle rocks reflect the cumulative sum of multiple alteration events, but to date, identifying distinct serpentinisation episodes has remained challenging due to limited knowledge of the spatial distribution of tracers of fluid-rock exchange. Here we present novel high spatial resolution (∼10 μm) boron, nickel, calcium, and lithium concentration maps combined with in situ boron isotope analyses of strongly serpentinised mantle peridotites from the Troodos ophiolite, Cyprus. Our maps indicate strongly heterogenous boron concentrations with high boron concentrations in early formed serpentine replacing olivine but much lower boron contents in mesh-textured serpentine and bastitic pyroxene. Late stage crosscutting serpentine veins have very low boron concentrations. In contrast, boron isotope measurements, made at coarser scales, are remarkably uniform (mean value +11.9 ± 3.2 %, 1σ, n = 49). We interpret the high boron serpentine as reflecting the partial preservation of an early pervasive serpentinisation episode by fluids with high boron concentrations sourced from the dehydration of the subducting Cyprus slab. Subsequent serpentine phases with moderate to low boron reflect progressive recrystallisation and leaching by low boron concentration meteoric waters.</p
