Ivanovo State University (Russian: Ива́новский госуда́рственный университе́т) or IvSU (Russian: ИвГУ) is in Ivanovo, about 300 km east of Moscow, Russia. The University was founded in 1918; before 1974 was called Ivanovo State Pedagogical Institute.IvSU has accreditation and license from the Russian Ministry of Education. It is a member of Euroasian association of universities and Russian Association of Classical Universities, co-operates with educational institutions of Germany (Passau University and the Berlin Technical University), Sweden (University of Uppsala), Denmark (Aarhus University, Institute of Business and Technology in Herning) and China (Xiangtan University) among many others. The training of international students has started in 60's with the programs for the students from socialist countries. In 1982 the separated Department of Russian as a Foreign Language was created in order to prepare international students to study in Russia. It was the first university in the region offering degrees unusual in the Soviet system: economics (1976), law (1962), sociology (1999) and applied programming.IvSU has different types of programs from traditional five years specialist degree to four years bachelor's degree and two years master's degree following the modernization of Russian education system and Bologna Process. Also, the university has 10 specialized councils that grant the degree of Kandidat Nauk as well as postgraduate degree of Doktor Nauk in the fields of history, technical science, linguistics, philosophy and economics.
A comprehensive study of the supramolecular organization of floating layers and Langmuir–Schaefer films of the heteronuclear complex “phthalocyanine-O-subphthalocyanine” is reported. The molecular packing of the studied compound in monolayer structures on a water surface was simulated, and the unit-cell parameters of the monolayer were calculated. Using grazing-incidence X-ray diffraction, X-ray standing-wave technique, and Brewster angle microscopy data, it was shown that this compound forms stable and uniform X-ray amorphous layers with edge-on molecular packing at the air/water interface. The obtained results open the possibility of effectively using thin-film structures based on the obtained Langmuir layers in nanoelectronics.
Organic compounds have the widest practical application, and the methodology of their synthesis is often developed specifically to solve applied problems in medicinal chemistry, catalysis, materials chemistry, agriculture, food industry, and the creation of electronic and sensor devices. This is due to the huge variety of properties and functional capabilities of organic substances, as well as the ability to fine-tune their structure to impart certain practically useful characteristics. Currently, the number of organic compounds used in various fields of industry, medicine, and agriculture is in the hundreds of thousands, and their number continues to grow steadily due to the rapid development of synthetic organic chemistry and predictive methods for determining properties, including using artificial intelligence. This collective review is devoted to the achievements of Russian chemists in the field of practically oriented organic chemistry over the past 5–10 years. The review presents the achievements of leading research teams representing both RAS institutes and Russian universities, from Kaliningrad to Siberia.
Abstract Background Eastern hunter-gatherers (EHG) contributed varying proportions of genetic ancestry to many modern Europeans. However, how this contribution shaped the human leukocyte antigen (HLA) gene diversity remains unexplored. Sakhtysh in western Russia comprises one of the largest EHG-affiliated burial complexes. The site's continuous use offers a rare opportunity to investigate the genetic history, immune-gene diversity, and pathogen exposure within a hunter-gatherer population. Results Genome-wide data from 36 individuals (spanning Lyalovo–Volosovo traditions, 6800–4800 cal BP) place the Sakhtysh population within the EHG cluster, with high genetic affinity to contemporaneous groups across northwestern Russia and the eastern Baltic. This genetic composition remained stable for over two millennia and there is no evidence of admixture with neighboring western hunter-gatherer or farmer groups. We report HLA genotypes for 27 Sakhtysh individuals, representing the first true HLA calls from ancient hunter-gatherers. HLA diversity is low in the Sakhtysh population, likely due to their small population size. Specific alleles like B*27:05 are observed at high frequencies (~ 50%), despite being relatively rare in modern populations, suggesting shifts in selective pressures. Pathogen screening identified a restricted spectrum of causal agents including possible zoonoses with Erysipelothrix rhusiopathiae and chronic infections with hepatitis B virus and parvovirus B19. Conclusions The Sakhtysh community shows genetic continuity across cultural transitions. This population exhibits limited HLA diversity and unexpectedly high frequency of certain alleles. These patterns were likely influenced by low pathogen diversity and possible adaptation to specific environmental factors.
The article presents the results of a study of teachers’ psychological health and adolescents’ hardiness in the educational environment. The goal is to explore these phenomena and their relationship. The study used observation and testing methods, including A. V. Kozlov’s Individual Model of Psychological Health for teachers and S. Maddi’s Hardiness Survey for students and teachers. The study identified the levels of psychological health and hardiness. It also revealed their relationship, emphasising the need for comprehensive psychological and pedagogical support.
The absorption and fluorescence properties of individual luminescent mesogenic star-shaped tristriazolotriazine derivative (TTT), CdSe/ZnS quantum dots (QDs), and their hybrid TTT/QDs systems were investigated in solutions and in Langmuir-Schaefer (LS) films. Analysis of compression isotherm of floating Langmuir layers demonstrated that the mechanical properties (rigidity) and structural characteristics (phase behavior) of TTT floating Langmuir layers can be effectively tuned by varying the QDs content. It was revealed that TTT/QDs systems exhibit photophysical responses depending on excitation wavelength (290 or 500 nm) and sample morphology (solution or thin film). In solution, the hybrid system can function as a dual-emissive, excitation-selective platform. The emission intensity in the LS films increases non-linearly with the number of layers, reflecting the cumulative contribution of successive layers. At the same time, the increase in QD content suppresses TTT-centered emission. The obtained results evidence that TTT/QDs hybrid materials can be promising candidates for switchable luminescent and sensing applications.
