Nonresonant Raman and inelastic X-ray scattering in the charge-density-wave phase of the spinless Falicov-Kimball model

Nonresonant inelastic light and X-ray scattering is investigated for the spinless Falicov-Kimball model on an infinite-dimensional hypercubic lattice with a charge-density-wave phase at half filling. The many-body density of states (DOS) is found for different values of the Coulomb repulsion $U$, ranging from a dirty metal to a Mott insulator. At zero temperature, the charge gap is exactly equal to $U$; increasing the temperature rapidly fills the gap with subgap states. The nonresonant response function for Raman and inelastic X-ray scattering shows peaks connected with transitions over the gap and transitions that involve subgap states. In the case of X-ray scattering (when both energy and momentum are transferred), the response function illustrates features of dynamical screening (vertex corrections) in the different (nonresonant) symmetry channels ($A_{\rm 1g}$ and $B_{\rm 1g}$). We also derive and verify the first moment sum rules for the (nonresonant) Raman and inelastic X-ray response functions.Comment: 19 pages, 17 figure

Raise and characterization of a bread wheat hybrid line (Tulaykovskaya 10 × Saratovskaya 29) with chromosome 6Agi2 introgressed from Thinopyrum intermedium

Wheatgrass Thinopyrum intermedium is a source of agronomically valuable traits for common wheat. Partial wheat–wheatgrass amphidiploids and lines with wheatgrass chromosome substitutions are extensively used as intermediates in breeding programs. Line Agis 1 (6Agi2/6D) is present in the cultivar Tulaykovskaya 10 pedigree. Wheatgrass chromosome 6Agi2 carries multiple resistance to fungal diseases in various ecogeographical zones. In  this work, we studied the transfer of chromosome 6Agi2 in hybrid populations Saratovskaya 29×Tulaykovskaya 10 (S29×T10) and Tulaykovskaya 10×Saratovskaya 29 (T10×S29). Chromosome 6Agi2 was identified by PCR with chromosome-specific primers and by genomic in situ hybridization (GISH). According to molecular data, 6Agi2 was transmitted to nearly half of the plants tested in the F2 and F3 generations. A new breeding line 49-14 (2n = 42) with chromosome pair 6Agi2 was isolated and characterized in T10×S29 F5 by GISH. According to the results of our field experiment in 2020, the line had high productivity traits. The grain weights per plant (10.04±0.93 g) and the number of grains per plant (259.36±22.49) did not differ significantly from the parent varieties. The number of grains per spikelet in the main spike was significantly higher than in S29 (p ≤ 0.001) or T10 (p ≤ 0.05). Plants were characterized by the ability to set 3.77±0.1 grains per spikelet, and this trait varied among individuals from 2.93 to 4.62. The grain protein content was 17.91 %, and the gluten content, 40.55 %. According to the screening for fungal disease resistance carried out in the field in 2018 and 2020, chromosome 6Agi2 makes plants retain immunity to the West Siberian population of brown rust and to dominant races of stem rust. It also provides medium resistant and medium susceptible types of response to yellow rust. The possibility of using lines/varieties of bread wheat with wheatgrass chromosomes 6Agi2 in breeding in order to increase protein content in the grain, to confer resistance to leaf diseases on plants and to create multiflowered forms is discussed

Effect of pectin and pectin-containing products on the oxidative processes in the tissues of salivary glands in white rats under the combined excess nitrates and sodium fluoride

В эксперименте на 20 белых крысах исследовано состояние NO-синтазного и аргиназного путей метаболизма L-аргинина и окислительных процессов в тканях поднижнечелюстных слюнных желез (СЖ) при сочетанном токсическом действии нитрата и фторида натрия и добавлении к рациону крыс яблочного пектина и пектиносодержащих продуктов (муки овсяной крупы). Выявлено, что применение яблочного пектина предупреждает чрезмерную активацию в тканях СЖ NO-синтазы и угнетение ферментов аргиназного пути метаболизма L-аргинина (орнитиндекарбоксилазы). Добавление в рацион крысам яблочного пектина и муки овсяной крупы снижает продукцию в тканях СЖ супероксидного анион-радикала митохондриальной электронно-транспортной цепью, ограничивает пероксидное окисление липидов, улучшает их белоксинтезирующую функцию. Кроме того, введение в корм яблочного пектина существенно повышает в СЖ антиоксидантный потенциал, активность супероксиддисмутазы и каталазы.The experiments on 20 white rats was aimed to study the state of NO-synthase and arginase ways for Larginine metabolism and oxidation processes in the tissues of submandibular salivary gland (SG) exposed to the combined toxic effect of sodium nitrate and fluoride against the background of the diet including apple pectin and pectin-containing products (oatmeal). It has been revealed the apple pectin prevents excessive NO-synthase activation in the SG tissues as well as the inhibition of arginase pathway enzymes of L-arginine metabolism (ornithine decarboxylase). Supplementing of apple pectin and pectin-containing food (oatmeal) to the usual diet of the rats reduces the production of superoxide anion radical by mitochondrial electron transport chain in the SG tissue, limits lipid peroxidation, improves the protein synthesis function. In addition, the introduction of apple pectin into the diet significantly increases the antioxidant potential in SG, as well as the activity of superoxide dismutase and catalase

Modeling of the Filtration Processes in a Rectangular Area Soils Using the Darcy

In the framework of the research described in this paper we implemented the numerical algorithm and the program for the implementation of the algorithm, which makes it possible to calculate pressure field in the examined region and established convergence of the iterative process at optimal selection of the relaxation parameter. The obtained results enable carrying out estimation of the ground water level and propagation patterns under conditions of appropriate environmental characteristics of flow in the presence of varying geometrical configuration of outflow zones through the examined surface.The modelling of filtration processes in a rectangular plot of soil using the Darcy equations might also be used in the problems on estimating water quality, in the tasks on preventing flood waters, floods or mudflows. Such a simulation also makes it possible to explore the phenomena of fluid propagation in soils given the prospects of development of shale gas deposits in the regions of Lviv, Ternopil, Ivano-Frankivsk oblasts (Ukraine). Thus, the applied aspect of the use of the obtained scientific result is the possibility to improve the developed mathematical model of filtration processes through the inclusion of morphological characteristics of river and the river system. This is a prerequisite for obtaining operational data on a change in the level of soil and flood waters at a specified point in time in order to ensure ecological safety of the environmen
