MORPHOLOGICAL CHANGES IN ORGANS AND TISSUES AT SUBCHRONIC INTOXICATION WITH BENZODIAZEPINE MEDICATIONS (EXPERIMENTAL RESEARCHES)

Morphological changes in tissues and organs at subchronic intoxication of white rats with 1,4-benzodiazepines synthetic medications (alprazolame, mezapame, diazepame, and nozepame) are studied in an experiment. Pathomorphological changes in tissues of liver, kidneys, brain and reproductive system that can lead to the development of industrially caused diseases in the employees of benzodiazepines production are revealed

Positive Quantum Brownian Evolution

Using the independent oscillator model with an arbitrary system potential, we derive a quantum Brownian equation assuming a correlated total initial state. Although not of Lindblad form, the equation preserves positivity of the density operator on a restricted set of initial states

Measurement of Γee(J/ψ)\Gamma_{ee}(J/\psi) with KEDR detector

The product of the electronic width of the $J/\psi$ meson and the branching fractions of its decay to hadrons and electrons has been measured using the KEDR detector at the VEPP-4M $e^+e^-$ collider. The obtained values are: $\Gamma_{ee}(J/\psi) = 5.550 \pm 0.056 \pm 0.089 \, \text{keV},$ $\Gamma_{ee}(J/\psi) \cdot \mathcal{B}_\text{hadrons}(J/\psi) = 4.884 \pm 0.048 \pm 0.078 \, \text{keV},$ $\Gamma_{ee}(J/\psi) \cdot \mathcal{B}_{ee}(J/\psi) = 0.3331 \pm 0.0066 \pm 0.0040 \, \text{keV}.$ The uncertainties shown are statistical and systematic, respectively. Using the result presented and the world-average value of the electronic branching fraction, one obtains the total width of the $J/\psi$ meson: $\Gamma = 92.94 \pm 1.83 \, \text{keV}.$ These results are consistent with the previous experiments.Comment: 19 pages, 13 figure

Beyond African orality: digital preservation of Mandinka ʿAjamī archives of Casamance

This article focuses on the digital preservation of African sources written in Mandinka ʿAjamī, i.e. the enriched form of the Arabic script used to write the Mandinka language for centuries. ʿAjamī writing has been utilized to document intellectual traditions, histories, belief systems, and cultures of non-Arab Muslims around the world. ʿAjamī texts have played critical roles in the spread of Islam in Africa and continue to be used for both religious and non-religious writings. However, African ʿAjamī texts such as those of the Mandinka people of Casamance in southern Senegal are not well known beyond local communities. ʿAjamī texts in Mandinka and other Mande languages are among the least documented. Only a few Mande ʿAjamī texts are available to scholars. Thanks to the British Library’s Endangered Archives Programme (EAP), Africa’s rich written heritage in ʿAjamī and other scripts previously unavailable to academics is being preserved and made universally accessible.EAP1042 - Endangered Archives Programme, British LibraryAccepted manuscrip

Studies of the ambient light of deep Baikal waters with Baikal-GVD

The Baikal-GVD neutrino detector is a deep-underwater neutrino telescope under construction and recently after the winter 2023 deployment it consists of 3456 optical modules attached on 96 vertical strings. This 3-dimensional array of photo-sensors allows to observe ambient light in the vicinity of the Baikal-GVD telescope that is associated mostly with water luminescence. Results on time and space variations of the luminescent activity are reviewed based on data collected in 2018-2022

Monitoring of optical properties of deep waters of Lake Baikal in 2021-2022

We present the results of the two-year (2021-2022) monitoring of absorption and scattering lengths of light with wavelength 400-620 nm within the effective volume of the deep underwater neutrino telescope Baikal-GVD, which were measured by a device Baikal-5D No.2. The Baikal-5D No.2. was installed during the 2021 winter expedition at a depth of 1180 m. The absorption and scattering lengths were measured every week in 9 spectral points. The device Baikal-5D No.2 also has the ability to measure detailed scattering and absorption spectra. The data obtained make it possible to estimate the range of changes in the absorption and scattering lengths over a sufficiently long period of time and to investigate the relationship between the processes of changes in absorption and scattering. An analysis was made of changes in absorption and scattering spectra for the period 2021-2022

Large neutrino telescope Baikal-GVD: recent status

The Baikal-GVD is a deep-underwater neutrino telescope being constructed in Lake Baikal. After the winter 2023 deployment campaign the detector consists of 3456 optical modules installed on 96 vertical strings. The status of the detector and progress in data analysis are discussed in present report. The Baikal-GVD data collected in 2018-2022 indicate the presence of cosmic neutrino flux in high-energy cascade events consistent with observations by the IceCube neutrino telescope. Analysis of track-like events results in identification of first high-energy muon neutrino candidates. These and other results from 2018-2022 data samples are reviewed in this report
