Abstract

The Nuclotron-base Ion Collider fAcility (NICA) is under construction at the Joint Institute for Nuclear Research (JINR), with commissioning of the facility expected in late 2022. The Multi-Purpose Detector (MPD) has been designed to operate at NICA and its components are currently in production. The detector is expected to be ready for data taking with the first beams from NICA. This document provides an overview of the landscape of the investigation of the QCD phase diagram in the region of maximum baryonic density, where NICA and MPD will be able to provide significant and unique input. It also provides a detailed description of the MPD set-up, including its various subsystems as well as its support and computing infrastructures. Selected performance studies for particular physics measurements at MPD are presented and discussed in the context of existing data and theoretical expectations., Comment: 53 pages, 68 figures, submitted as a Review article to EPJA

Abstract

The studies of bottom sediments of the Yenisei River from 2006 to 2016 near the Mining and Chemical Combine (MCC) and at a distance of up to 250 km from it downriver revealed an increased content of the radionuclide 60Co (including radioactive microparticles) in the upper layers. The specific activity of 60Co in the river floodplain increased due to the extreme flood of 2006. The 137Cs/60Co ratio in the surface layers of bottom sediments after the flood varied from 0.2 to 1.0 and differed significantly from the 137Cs/60Co ratio (2.5–6.0) in the surface layers before the flood. The increased content of 60Co in the upper layers of bottom sediments can serve as a marker of the 2006 event for calculating the sedimentation rate and dating the input of radionuclides into bottom sediments.

Abstract

A measurement of the transverse mu (+) polarization, P-T, in K+ --> pi (0)mu (+)nu decay was performed using stopped kaons. For 1996-1997 data the results are P-T = -0.0042 +/- 0.0049(stat) +/- 0.0009(syst) and Im(xi) = -0.013 +/- 0.016(stat)+/- 0.003(syst), where Im(xi) is T-violating physics parameter.

Abstract

An experiment E246 at the 12-GeV proton synchrotron at KEK (KEK-PS), which is searching for the T-violating transverse muon polarization (P-mu(perpendicular to)) in K+ --> pi (0)mu (+)nu decay, is described. The search is sensitive to new mechanisms of T or CP violation beyond the Standard Model. The initial results of P-mu(perpendicular to) = -0.0042+/-0.0049(stat.)+/-0.0009(syst.) and the T-violating parameter Im(xi) = -0.013+/- 0.016(stat.) +/- 0.003(syst.) were determined from the data taken in 1996 and 1997.

Abstract

In a kinematically complete setting, the $K^+ \to \pi^+ \pi^0 \pi^0$ decays of stopped $K^+$ were measured. In the frame work of the Weinberg polynomial expansion, the coefficients up to quadratic terms were deduced. The results are in good agreement with previous measurements and consistent with CP conservation expectations. The empirical $\Delta I=1/2$ rule is violated.

Abstract

Age-dependent accumulation of Cs in the muscles and bodies of the pike Esox lucius (aged two to seven years) inhabiting a section of the Yenisei River polluted with artificial radionuclides has been studied. The content of Cs in muscles varied from 0.5 to 7.0 Bq/kg of fresh weight. The maximum content of the radionuclide has been found in juveniles. The content of Cs in pike muscles and body decreased considerably with age. The high content of Cs in the muscles of juveniles is probably a consequence of their higher intensity of feeding as compared to older individuals, which is due to the intense growth of juveniles.

Abstract

Experiments with macromycetes Pleurotus ostreatus, Neonothopanus nambi, and Agaricus bisporus demonstrated for the first time that live mycelium of mushrooms, cultivated on a liquid culture medium, can efficiently take up dissolved Am in its biomass. Biochemical fractionation of the mycelium biomass demonstrated for the first time that the major fraction (up to 90%) of Am accumulated in the mycelium is bonded to structural polysaccharides of the cell walls. The sorption capacity of cell wall polysaccharides for Am is 2.7-3.6 times higher than that of the initial mycelium biomass, and the activity concentration of Am in the polysaccharides reached 950 Bq g dry weight.

43. Accumulation of 60Co, 90Sr, 137Cs, 238U and transuranic elements by berry shrubs in forest ecosystems of the Yenisei river basin

Author

Dementyev, D. and Bolsunovsky, A.

Abstract

The study investigates accumulation of radionuclides in 5 species of berry shrubs in forests of the Yenisei River basin (the Krasnoyarskii Krai, Russia). Activity concentrations of 60Co, 90Sr, 137Cs, 238U and transuranic elements in aboveground organs of the shrubs have been determined and their transfer factors calculated. Analysis of the calculated TFs shows that shrubs concentrate 90Sr more effectively than other study elements (TF = 0.25–1.9). The highest concentration of 137Cs is recorded in the berries and leaves of Ribes nigrumand Rubus idaeus. For these species, the range of 137Cs TFs (0.006–0.027) overlaps with the range of 238U TFs (0.004-0.018). For the aboveground parts of Ribes nigrum, TFs for transuranic radionuclides (0.01–0.056) are similar to or higher than the TFs for 238U and 137Cs.

Abstract

Responses of cytogenetic and growth endpoints of the aquatic plant Elodea canadensis were studied using the plants collected from non-contaminated control areas of the Yenisei River and exposed to external γ-radiation for 11-13 days in the laboratory. Elodea canadensis was exposed to 0.5-25 mGy/day γ-radiation dose rates from a 137 Cs source. The total number of aberrant cells and total root length were more sensitive elodea endpoints to γ-radiation than total shoot length and mitotic index of elodea. Radiation sensitivity of elodea can be compared with the sensitivity of such a Reference Plant as Wild Grass (1-10 mGy/day) recommended by the ICRP. Thus, the aquatic plant Elodea canadensis can be used as a radiation bioindicator., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier Ltd.

Abstract

Long-term trends of artificial radionuclides, from 2003 to 2018, in two abundant species of macrophytes, shining pondweed, Potamogeton lucens, and water moss, Fontinalis antipyretica, have been analyzed to estimate the indicative reliability of these two species as biomonitors of radioactive contamination in a river system and to quantify the decrease in the content of artificial radionuclides in the Yenisei River. Time-dependent trends of artificial radionuclides in the biomass of these species were similar, resulting in estimates of effective half-lives for 54 Mn, 58 Co, 60 Co, 65 Zn, 137 Cs, and 152 Eu similar for both species. Concentrations of artificial radionuclides in biomass of shining pondweed and water moss correlated with annual discharges of the radionuclides to the Yenisei at different levels of significance, and the strongest (R 2  > 0.7) positive correlation (p < 0.05) was obtained for 60 Co, 65 Zn, and 152 Eu. Concentrations of 60 Co, 137 Cs, and 152 Eu in water moss were 2-7.5 times higher than in shining pondweed, and considerable percentages of those isotopes were recorded in extracellular particulate matter, which was largely represented by epiphytic diatoms. Higher concentrations of artificial radionuclides in the biomass of water moss can be considered as an advantage of water moss as a monitor of radioactive contamination of the Yenisei, while shining pondweed is more useful for estimation of annual deposits of radionuclides in vegetation of the Yenisei and spatial transfer of radionuclides downstream of the discharge site. Despite differences in concentrations of artificial radionuclides, both species can be considered as reliable indicators of radioactive contamination of the river on a long-term scale., (Copyright © 2020 Elsevier Ltd.

Abstract

Purpose: The purpose of this study was to assess the long-term effects of gamma-radiation, including low-dose radiation, on growth parameters of onion ( Allium cepa ) seedling roots 6-10 days after irradiation., Materials and Methods: Onion seedlings were exposed to a 137 Cs gamma source at doses ranging from 0.1 to 10 grays (Gy). Responses of root and shoot length growth were studied 6 and 10 days after irradiation., Results: Our results showed inhibition of the root and shoot length growth 6 days after exposure at all doses, including the low dose - 0.1 Gy. At a later point in time (day 10), root and shoot inhibition was only observed after irradiation at high doses (above 5 Gy), and that suggested the occurrence of cell repair after irradiation at low doses. The results indicated that the length of seedling roots was more sensitive to gamma-irradiation than the shoot length., Conclusion: The results of the study suggested that short-term gamma-irradiation of onion seedlings (absorbed doses of 0.1-10 Gy) caused inhibition of plant growth 6 and 10 days after irradiation. The dose dependence of the onion root length was linear. The present study showed for the first time that short-term low-dose gamma-irradiation could induce long-term negative effects on plant growth.
