To the 100th anniversary of Irina Antonova
No full textThis article is dedicated to the legendary Russian museum figure Irina Antonova (20.03.1922 —
30.11.2020), who worked at the Pushkin State Museum of Fine Arts for 75 years, 52 years of
which as its director. The development of the Pushkin State Museum of Fine Arts under the
leadership of Irina Antonova is seen by the author of this article as part of the evolution of
museum work in the Soviet Union and the Russian Federation. The article emphasizes that the Pushkin Museum was often ahead of its time, laying the groundwork for major changes. For
example, with the opening of the Museum of Private Collections as part of the State Museum
of Fine Arts, the rehabilitation of private collecting in the country took place. The December
Nights festival created by Irina Antonova in collaboration with the brilliant pianist Svyatoslav
Richter in 1981 became a matrix of art festivals that took place in various museums of the
country during the following decades. The Pushkin State Museum of Fine Arts was charged
with promoting Western art in the USSR, of which it brilliantly took the advantage when
started displaying works by Picasso, Matisse, Leonardo da Vinci’s Mona Lisa, masterpieces
of drawing from the Albertina Museum in Vienna, Western European and American paintings
from American museums and others famous exhibitions. This is the visible part of Irina
Antonova’s dynamic activity. She approached academic work no less thoroughly, as well as the
organization of study and cataloguing of the collection of the State Museum of Fine Arts. And,
of course, much credit must go to Irina Antonova for preparing the program for the development
and reconstruction of the Pushkin Museum, which has been repeatedly revised and is
being finalized before our very eyes under the direction of Marina Loshak
Variably saturated dual-permeability flow modeling to assess distributed infiltration and vadose storage dynamics of a karst aquifer – The Western Mountain Aquifer in Israel and the West Bank
No full textAvailable methods to quantify the recharge of karst aquifers usually rely on spatially and temporally aggregated precipitation measurements and simplified recharge models, employing transfer functions to account for the delay in infiltration and the distribution in time and space. They generally neglect the non-linear nature of infiltration dynamics through the vadose zone, characterized by dual flow behavior with slow diffuse and rapid focused recharge components. Here, we present a methodology that accounts for the physics of flow by employing a variably saturated dual-permeability flow model to simulate diffuse and preferential infiltration in a large-scale carbonate aquifer. The Western Mountain Aquifer (WMA) in Israel and the West Bank was selected as a suitable groundwater basin because of the large thickness of the vadose zone, extending over several hundred-meters, the availability of long-term data as well as the catchment size, stretching across a catchment area of circa 9000km2. Together, these characteristics allow the identification and quantification of the spatio-temporal distribution of the infiltration/recharge component, assessed at the level of the groundwater table. The presented methodology allows for improved water resources planning and generalization of the results, i.e., the robustness of large-scale model results with respect to local hydraulic parameter variations and data uncertainty. Semi-arid climate regions with a highly pronounced seasonality of precipitation and intense short-duration rainfalls, such as the Mediterranean region, represent a prime study location because of the clear and pronounced recharge input signals that are not superimposed by summer rainstorms. We simulate the complex dynamics of the dual-domain infiltration and partitioning of the precipitation input signal by employing HydroGeoSphere (HGS) for transient variably saturated water flow. Flow in the limestone rock matrix and high porosity system (i.e., conduits and fractures) is modeled by overlapping individual continua based on the bulk-effective Richards’ equation with van Genuchten (VG) parameters

Motif of Death in Irina Odoyevtseva’s Prose
No full textThe present paper brings an analysis of the motif of death in Irina Odoyevtseva’s novels "Zerkalo",
"Izolda" and "Angel smerti". In the prose of Odoyevtseva, who belonged to the younger generation of the
Russian Emigration (the first wave), death is a frequent motif. The author explores how Odoyevtseva
refers to Mikhail Lermontov’s poems and to the Celtic story of "Tristan and Iseult
Intravascular Inflammation Triggers Intracerebral Activated Microglia and Contributes to Secondary Brain Injury After Experimental Subarachnoid Hemorrhage (eSAH).
Full text linkActivation of innate immunity contributes to secondary brain injury after experimental subarachnoid hemorrhage (eSAH). Microglia accumulation and activation within the brain has recently been shown to induce neuronal cell death after eSAH. In isolated mouse brain capillaries after eSAH, we show a significantly increased gene expression for intercellular adhesion molecule-1 (ICAM-1) and P-selectin. Hence, we hypothesized that extracerebral intravascular inflammatory processes might initiate the previously reported microglia accumulation within the brain tissue. We therefore induced eSAH in knockout mice for ICAM-1 (ICAM-1(-/-)) and P-selectin glycoprotein ligand-1 (PSGL-1(-/-)) to find a significant decrease in neutrophil-endothelial interaction within the first 7 days after the bleeding in a chronic cranial window model. This inhibition of neutrophil recruitment to the endothelium results in significantly ameliorated microglia accumulation and neuronal cell death in knockout animals in comparison to controls. Our results suggest an outside-in activation of the CNS innate immune system at the vessel/brain interface following eSAH. Microglia cells, as part of the brain's innate immune system, are triggered by an inflammatory reaction in the microvasculature after eSAH, thus contributing to neuronal cell death. This finding offers a whole range of new research targets, as well as possible therapy options for patients suffering from eSAH

Identification of suitable sites for managed aquifer recharge under semi-arid conditions employing a combination of numerical and analytical techniques
No full textAbstract
Overpumping or overexploitation of groundwater is one of the major threats for aquifer systems in arid and semi-arid areas. Managed aquifer recharge (MAR) has been suggested by many researchers as a sustainable and effective method to alleviate negative impacts of overpumping. Optimizing artificial recharge considers the selection of suitable MAR sites in terms of surface and subsurface characteristics. While surface characteristics at potential MAR sites could be modified (e.g. slope, soil texture, etc.), subsurface characteristics cannot be changed through engineering work. Characteristics of the aquifer, such as depth to groundwater, play an important role in determining the capability of an aquifer to store a specific volume of infiltrated water. Currently, only a limited number of quoted researches are available that consider factors related to aquifer characteristics and the range of these factors to identify optimal MAR sites. In this study, a new approach is presented, that employs numerical groundwater modeling to generate MAR suitability maps considering sub-surface characteristics, such as depth-to-groundwater, aquifer transmissivity and specific yield. Multiple model-runs are conducted to simulate groundwater table response with respect to the volume of infiltrated water. Simulation results are used to calibrate a groundwater mound empirical equation that calculates the groundwater level increase as a function of the transmissivity and infiltrated water volume for a given value of aquifer’ specific yield, range of vertical hydraulic conductivities and a specific design and operation conditions of the MAR system. The empirical equation is employed in GIS to spatially calculate the height of groundwater mound beneath a hypothetical MAR site and to generate, based on that, suitability maps for MAR implementation. Assuming that MAR structures capture the median of monthly surface runoff rates at the respective wadi (catchment area), suitability maps are generated for different configurations/scenarios of aquifer hydraulic conductivity in a parameter study. The results highlight the importance of integrating aquifer characteristics (geometry and hydraulic parameters) and expected magnitudes and fluxes of infiltration water in delineating suitable sites for MAR.Georg-August-Universität Göttingen (1018
