Physiological Tests

A molecular genetic study of Kluyveromyces lactis yeasts isolated from various dairy products in the countries of the former Soviet Union and other regions of the world has been carried out. Based on physiological tests, four strains were selected that carry different LAC loci and are characterized by good fermentation intensity: VKM Y-1339 (LAC3), VKM Y-1333 (LAC3), NRRL Y-1118 (LAC1), and NRRL Y-1140 (LAC2). Eleven hybrids of the selected strains with different rates of lactose fermentation were obtained. No correlation was found between the intensity of lactose fermentation and the amino acid sequences of the LAC12 lactose permease gene of the LAC1, LAC2, and LAC3 loci. Apparently, a specific combination of genotypes of crossed strains has a more significant effect on the fermentation activity. The results obtained showed that inter-strain hybridization of K. lactis dairy yeast is an effective method for creating new strains with high fermentation capacity. Hybrids H2-3 (NRRL Y-1118 × VKM Y-1333) and H3-3 (NRRL Y-1140 × VKM Y-1333) with the highest ability to ferment lactose are of interest for further molecular genetic research and breeding programs. Key words: Kluyveromyces lactis, β-galactosidase, lactose permease, LAC4, LAC12, LAC1 locus, LAC2 locus, LAC3 locus, inter-strain hybridization, lactose fermentation, heterosis Acknowledgment - The authors are grateful to the Genomic Center of the Kurchatov Institute SRC---GosNIIgentika for sequencing the nucleotide sequences of the LAC12 genes for lactose permease on the Applied Biosystems 3730 automated analyzer.

Experimental Problem

ITER is presently the world's key thermonuclear project. This reactor should operate under the conditions of increased thermal and power loads. In this regard, an analysis of the behavior of structural materials during the reactor operation is an important theoretical and experimental problem. During the ITER operation, an important factor that affects the fuel turnover is the capture of hydrogen isotopes (especially radioactive tritium) into the reactor structural materials, which has an effect on both the radiation environment and the plasma parameters as a whole. Annealed CuCrZr alloy samples saturated in deuterium at various temperatures were studied using the thermal desorption spectroscopy (TDS) method at different saturation temperatures equal to 350oC, 400oC, 450oC, and 500oC. The saturation was carried out at a pressure of 5 atm for 25 h. The deuterium capturing process was studied on the TDS setup located at the NRC Kurchatov Institute. In the course of thermal desorption spectroscopy, samples were heated to a temperature of 977oC at a rate of 0.5 K/s. The influence of alloying additions in the CuCrZr alloy was analyzed. It is shown that in the obtained thermal desorption spectra there is a shift in the deuterium yield peak to the region of higher temperatures and an increased capture of deuterium with an increase in the sample saturation temperature in gaseous deuterium.

В статье рассматриваются вложения в 14 закрытых древнерусских крестах-энколпионах, обнаруженных на селищах Суздальского Ополья и в Новгороде. Вложения изучались с применением современных методов нейтронной томографии, оптической микроскопии, инфракрасной микроскопии, газовой хроматографии на приборной базе Национального исследовательского центра «Курчатовский институт». Полученные результаты свидетельствуют, что традиция вложений была вариативна, установленных правил отбора реликвий для вложения в ковчежцы не существовало. В качестве вложений использовались частицы дерева и ткани, нити, волос, для сохранения реликвий и герметизации створок широко применялась воскомастичная смесь. Вложения могли теряться и возобновляться, когда энколпионы находились в обиходе. Несмотря на производство крестов как стандартизированных изделий, вложенные в них реликвии были индивидуальны. Лабораторное изучение энколпионов подтверждает функциональное использование их как реликвариев в отдаленных областях средневековой христианской ойкумены, широкое распространение общехристианского почитания «движимых святынь» в Северо-Восточной Руси в XII–XIII вв. The paper reviews fragments of relics and materials from 14 closed Medieval Russia reliquary crosses found at unfortified settlements of Suzdal Opolye and in Novgorod. These fragments were studied with the use of modern methods of neutron tomography, optical microscopy, infrared microscopy, gas chromatography in the laboratories of the The Kurchatov Institute’ National Research Center. The results obtained reveal that the tradition of inserting relics was not rigid, there were no established rules for selecting holy relics for reliquary crosses. Besides physical remains such as human bones and hair, parts of wood and cloth were inserted as well; a mixture of wax and mastic resin was used to seal cross compartments. Inserted relics could be lost and replaced when reliquary crosses were in use. Despite production of crosses as standardized items, relics inserted in them were individual. The laboratory studies of these reliquary crosses confirm their functional use as reliquaries in remote areas of the Medieval Christian oecumene as well as veneration of these ‘portable’ sacred objects in the northeastern parts of Medieval Russia in the twelfth–thirteenth centuries which was typical for the entire Christian World.
