Effect of gases on biochemical stabilization
2019
International audience; Lipid or protein are sensitive to peroxidation and inert gas limit or stop adulterations. Unsaturated lipids are peroxided by ground state dioxygen in presence of catalysts (iron, enzymes) or after thermal dissociation of C=C bond, and by excited state dioxygen without any assistance (photo-oxidation). Inerting fragile oils by bubbling with dinitrogen or carbon dioxide that are soluble gas in oil slows oxidation process during storage or frying. In a same way, limit the oxidation of the tryptophan residues of protein is possible by reducing oxygen content. Oxidation leads also to oxidation of thiol in disulfide, which induced protein cross-linked and decay of functio…
Magnetofection of acoustically active „magnetic microspheres“ (Magnetobubbles) — Induction of angiogenesis via non-viral transfection of VEGF
2009
Adenoviral transduction of the VEGF gene in an oversized skin flap increases flap survival and perfusion. In this study we investigated the potential of magnetofection of magnetic lipospheres containing VEGF165-cDNA on survival and perfusion of ischemic skin flaps and evaluated the method with respect to the significance of applied magnetic field and ultrasound.
Measurement of Atmospheric Neutrino Oscillations at 6–56 GeV with IceCube DeepCore
2018
We present a measurement of the atmospheric neutrino oscillation parameters using three years of data from the IceCube Neutrino Observatory. The DeepCore infill array in the center of IceCube enables the detection and reconstruction of neutrinos produced by the interaction of cosmic rays in Earth's atmosphere at energies as low as ∼5 GeV. That energy threshold permits measurements of muon neutrino disappearance, over a range of baselines up to the diameter of the Earth, probing the same range of L/Eν as long-baseline experiments but with substantially higher-energy neutrinos. This analysis uses neutrinos from the full sky with reconstructed energies from 5.6 to 56 GeV. We measure Δm322=2.31…
Measurement of the Fluctuations in the Number of Muons in Extensive Air Showers with the Pierre Auger Observatory
2021
The successful installation, commissioning, and operation of the Pierre Auger Observatory would not have been possible without the strong commitment and effort from the technical and administrative staff in Malargue. We are very grateful to the following agencies and organizations for financial support: Argentina-Comision Nacional de Energia Atomica, Agencia Nacional de Promocion Cientifica y Tecnologica (ANPCyT), Consejo Nacional de Investigaciones Cientificas y Tecnicas (CONICET), Gobierno de la Provincia de Mendoza, Municipalidad de Malargue, NDM Holdings and Valle Las Lenas; in gratitude for their continuing cooperation over land access; Australia-the Australian Research Council; Brazil…
A sharp estimate for Neumann eigenvalues of the Laplace-Beltrami operator for domains in a hemisphere
2018
Here, we prove an isoperimetric inequality for the harmonic mean of the first [Formula: see text] non-trivial Neumann eigenvalues of the Laplace–Beltrami operator for domains contained in a hemisphere of [Formula: see text].
What is your couple type? Gender ideology, housework-sharing, and babies
2015
AbstractBACKGROUNDIt is increasingly acknowledged that not only gender equality but also gender ideology plays a role in explaining fertility in advanced societies. In a micro perspective, the potential mismatch between gender equality (i.e., the actual sharing taking place in a couple) and gender ideology (i.e., attitudes and beliefs regarding gender roles) may drive childbearing decisions.OBJECTIVEThis paper assesses the impact of consistency between gender equality in attitudes and equality in the division of household labour on the likelihood of having another child, for different parities.METHODSRelying on two-wave panel data of the Bulgarian, Czech, French, Hungarian, and Lithuanian G…
Up with ecology, down with economy? : The consolidation of the idea of climate change mitigation in the global public sphere
2018
Building on theories of valuation and evaluation, we develop an analytical framework that outlines six elements of the process of consolidation of an idea in the public sphere. We then use the framework to analyse the process of consolidation of the idea of climate change mitigation between 1997 and 2013, focusing on the interplay between ecological and economic evaluations. Our content analysis of 1274 articles in leading newspapers in five countries around the globe shows that (1) ecological arguments increase over time, (2) economic arguments decrease over time, (3) the visibility of environmental nongovernmental organizations as carriers of ecological ideas increases over time, (4) the …
Partycypacja na siłę i jej nieoczekiwane konsekwencje: państwowy socjalizm a nowoczesna klasa robotnicza
2016
W artykule omawiane są przemiany społeczne w Polsce, przyniesione przez państwowy socjalizm po drugiej wojnie światowej. Opierając się na założeniu o „prześnionej rewolucji” (Leder 2014), argumentuje, że metody, którymi ówczesne władze mobilizowały ludzi do działania, nosiły znamiona partycypacji społecznej, choć w wielu przypadkach była to partycypacja inspirowana, a nawet wymuszona. Jako element mobilizacji społecznej przyczyniła się do uprawomocnienia klas niższych – robotników i chłopów. Skutkiem tego procesu była zdolność tych klas do podjęcia dyskusji z decydentami, dzięki czemu początkowi „beneficjenci” socjalizmu nie tylko byli w stanie sprzeciwić się aparatowi partyjnemu i przyczyn…
O prywatności zatrudnionych w świecie pracy ery technologicznej
2022
Główna teza badawcza artykułu jest następująca: wszelkie analizy dokonujących się obecnie przeobrażeń świata pracy i zachodzących w nim zjawisk będą miały sens jedynie w łączności z zasadami działania algorytmów (technologii algorytmicznej), które je w określony sposób interpretują i od których są nieodłączne. Z kolei metoda algorytmicznego zarządzania osadzona jest, jak każda inna metoda, w sferze praw podstawowych jednostki, nie może naruszać ich rdzenia (istoty), nie może ich w żaden sposób ignorować. Ani same algorytmy, ani ich działanie nie mogą być więc interpretowane w izolacji, ale wyłącznie w sposób zgodny zasadami podstawowymi Konstytucji oraz jej systemem wartości
Analysis of the performance of the TES algorithm over urban areas
2014
International audience; The temperature and emissivity separation (TES) algorithm is used to retrieve the land surface emissivity (LSE) and land surface temperature (LST) values from multispectral thermal infrared sensors. In this paper, we analyze the performance of this methodology over urban areas, which are characterized by a large number of different surface materials, a variability in the lowest layer of the atmospheric profiles, and a 3-D structure. These specificities induce errors in the LSE and LST retrieval, which should be quantified. With this aim, the efficiency of the TES algorithm over urban materials, the atmospheric correction, and the impact of the 3-D architecture of urb…
