From the Dreyfus Affair to the Albertine Affair. Sociopoetics of conspiracy in À la recherche du temps perdu
Authors:   CELIS, Université Clermont Auvergne, LEMAIRE Julie
Published: November 2024

French Belle Époque is characterized by a spy mania. During this time, fights against traitors are multiplying. In this article, we would like to show how this social discourse gets into Proust’s novel À la recherche du temps perdu and fuels at the same time an imagination and a poetics of the conspiracy. First, this imagination belongs to armchair conspiracists. Between Dreyfus affair and Eulenburg affair they have indeed a lot to do. This imagination belongs then to the narrator, who is convinced that he is at the heart of a conspiracy, which turns the novel into a paranoid detective story. But he is perhaps the victim of a trick played on him by his imagination. Affected in turn by suspicion, the reader must also become a detective, in search of the traces that form the frame of the conspiracy narrative. More generally, the analysis of the Proustian imagination of conspiracy brings to light a number of interactions concerning a society that also seems to have entered the age of suspicion, fragmented into “little clans” that operate on the model of secret societies.

A number of 3-aryl-5,6-dihydroimidazo[2,1-b][1,3]thiazoles were synthesized by cyclocondensation of imidazolidine-2-thione with phenacyl bromides, and their antimicrobial and antioxidant activity was evaluated. Bioscreening confirmed the moderate antibacterial activity against the reference strains of bacteria Staphylococcus aureus, Escherichia coli and Proteus vulgaris and excellent antifungal activity against Candida albicans. It was found that 3-(4-chlorophenyl)-5,6-dihydroimidazo[2,1-b]thiazole 4h (MIC = 15.625 μg/ml) has twice the antifungal effect compared to the control drug Furacilin. The study of the antioxidant activity of the synthesized compounds proved their ability to inhibit 60–97% of DPPH radicals. The best antiradical effect was found for 4-(5,6-dihydroimidazo[2,1-b]thiazol-3-yl)phenol 4e (I = 97%). A probable mechanism of its action was proposed involving the formation of a radical cation by the SET process. For the most active antioxidants 4e-g, reactivity and electrostatic surface potential were evaluated using the DFT method, and molecular docking was studied on the human peroxiredoxin 5 protein model.

STUDY OF THE DEFORMATION MODE OF THE ROCK MASS BASED ON THE DATA OF UNDERGROUND WATER MONITORING AT THE SEMIPALATINSK TEST SITE
Authors: Gorbunova E. M.
Published: November 2024

The paper proposes a scientific-methodological approach to determine the negative consequences of high-intensity impacts of large-scale explosions on the rock mass at the example of “Zarechye” site of the Semipalatinsk test site. The results of observations for the period of 1987–1990 over the underground water level in wells with depths from 75 to 200 m were used as the raw data. A comparative analysis of level alterations along a profile of reference wells is aimed to identify the areas of time-spatial redistribution of the underground flow. The change of hydrogeological condition is considered as an indicator of the changing deformation regime of the rock mass subjected to a high-intensity impact.

Authors: Kupchishin A. I. , Taipova B. G. , Voronova N. A. , Sushchikh A. M.
Published: November 2024

In this paper we consider the effect of high-energy electron irradiation, load and temperature on the mechanical properties of Mylar films. The simplest physical model is developed. Studies have shown that with an increase in the dose of electron irradiation to 104 Gy, there is a slow decrease in deformation for Mylar, and a further increase to 106 Gy leads to a sharp decrease in it. At the same time, with increasing temperature, the relative elongation increases by more than 50 %, associated with the growth of destructive processes in the material. The dependences of strain and stress on the dose of electron irradiation are described by exponential functions and are in satisfactory agreement with experimental data.

Published: November 2024

WWR-K is the research tank-type light-water heterogeneous reactor. Reactor operation started in 1967 with enrichment36 % in uranium-235. In 2016 reactor conversion to low-enriched uranium fuel (19.7 % in uranium-235) was implemented with the VVR-KN-type fuel assemblies (FA). In view of reactor operation, compact configuration of the core was chosen, where, following fuel burning up, side water reflector is gradually changed by beryllium one. Besides, an amount of work elements of the reactor control and protection system is increased in the new reactor core. Following results of measurement of the thermal neutron flux density, carried out in the core center in course of reactor physical startup, it has increased up to 2·1014 cm-2s-1. Thus, in terms of experimental capacities, reactor has gained after conversion in attractiveness. As is known, uranium fission is accompanied by generation of neutrons, which energies obey the Watt’s spectrum, that is, the spectrum peak is associated with the neutrons having the energy 0.7 MeV, whereas the neutron average energy comprises 2 MeV. Due to an enhanced amount of uranium-238 in the new low-enriched uranium fuel FA, neutron spectrum is making «harder». In the presented paper, neutron spectra in the core irradiation channels of re calculated by means of the computer code MCNP, and comparison of neutron spectra in the WWR-K reactor core with high-enriched uranium fuel against lowenriched fuel is conducted.

It was found that the strength properties of glass better in 1,5 at destruction than the PCB, and the deformation characteristics are almost the same. The measured experimental curves are satisfactorily described by the exponential model proposed by the authors. It is shown that the experimental dependences of s on lgt are nonlinear, which indicates the dependence of the mechanical stress of the textolite and glass-textolite material on the load speed.

APPLICABILITY OF GEOPHYSICAL METHODS FOR DETECTION OF RADIONUCLIDES TRANSFER STRUCTURES
Authors: Romanov A. M.
Published: November 2024

The paper studies the issues of mapping of hydrodynamic structures, both natural and technogenic ones, including the ones transferring radionuclides remotely by using electrical survey methods of apparent electrical resistivity (AR) and self-potential (SP). At that it has been taken into account that modern distribution of radionuclides from the foci of underground nuclear explosions (UNE) takes place mostly with underground waters. AR and SP methods allow to detect natural and technogenic crushed zones as well as establish the presence of underground water flows in them. The presence and location of water flows with radioactive contamination is established by measuring the tritium exhalation based on a methodology developed at the Institute of Geophysical Research. Examples are presented for the joined interpretation of AR, SP and tritium exhalation methods data that prove the applicability of the technique to detect hydrodynamic structures, including the ones transferring radionuclides.

Published: November 2024

An analysis of ring and linear zones of decreased electrical resistivity (AR) on the sites of underground nuclear explosions (UNE) of Semipalatinsk Test Site has been implemented; the zones were detected using field surveys and we established their difference from the AR distribution at the sites distanced from the UNE implementation places. Linear zones of decreased values of AR belong to the occurrences of geological faults renewed by nuclear explosions, whereas ring zones – to the faults occurred as a result of local mechanical impact of a UNE onto the background rocks. Linear and ring zones belong to the technogenic structures. It has been established that technogenic zones have significantly great contrast and width in comparison with the occurrences of natural zones of faults distanced from the UNEs epicenters. The presented interpretation of geo-electrical features does not contradict the existing geological views and can be used during the study of water flows and assessment of radiation safety in the interior of UNEs sites.

Excitation energy of the compound nuclei for all reactions was 21±2 MeV. Experiments were carried on the isochronous cyclotrone U-150M at The Institute of Nuclear Physics, Almaty city.тIt was shown that behavior of mass distributions Y(m) depends mainly on proton number in heavy and light fragmentsтthat are being formed. For isotopes of one element (237, 240, 242 Pu) charge distributions ofтfragments Y(Z) are almost the same. The discovered differences between behaviors of fragments mass distributions Y(m) and their energy distributions (Ek(m) и σ2(m)) points to these characteristics being formed at a different stages of fission process. Kinetic energy is determined by the conditions at rupture point, mass distributions are formed at earlier stages of fission process, when future fragments are still connected by a thick neck.

Published: November 2024

The results of a study of the degree of DNA damage in peripheral blood lymphocytes in residents of Dolon (Semipalatinsk region, East Kazakhstan region) are presented. The spontaneous level was analyzed after in vitro exposure to γ-radiation at a dose of 1 Gy and the assessment of the efficiency of repair 2.5 hours after irradiation. A cytogenetic study of the spontaneous frequency of chromosomal aberrations and radiosensitivity with additional radiation exposure was also conducted. A significant increase in the degree of DNA damage and cytogenetic disorders in the inhabitants of the Dolon pod was shown compared with the control in the study of the spontaneous level. The repair efficiency, determined usinga Comet-test and radiosensitivity based on cytogenetic analysis with additional irradiation of the cells of the patients, varied significantly within different individuals. These parameters in specific individuals may be of great importance for individual retrospective dose assessment during acute or chronic exposure or when living in radiocontaminated regions. A comparative analysis of the data obtained using the methods used revealed a significant positive correlation between the spontaneous frequency of chromosomal abnormalities and the efficiency of repair.

Published: November 2024

At the current stage of space exploration development, missions to the Moon and geostationary orbit are relevant. Enhancing of power supply level of such missions requires innovative technology development. Nuclear rocket engines and engines with use of solar energy are considered among such technologies. In a number of projects, such engines use intermediate heat energy accumulators, which complicates and increases the cost of construction. This embodiment uses a circuit that enables solar engine to operate with any orientation of the thrust direction towards the sun. The dependence of specific thrust of such engine on maximum heating temperature of working fluid (hydrogen) is shown. Such engines provide the ability to return to Earth at a speed of 8 km/s instead of 11 km/s, which increases flight safety and makes propulsion system reuse efficient.
