The practical activity of development of a system of tasks as an important condition for training a future teacher for a digital school

The problem and the aim of the study. A teacher of a digital school, according to the requirements of the standard of professional activity, must possess such universal qualities related to information and communication technologies, formed communicative competence, the ability to work in a team. The formation of the relevant skills within the framework of university education is complicated by a number of problems of a different nature. The authors suggest organizing a practice of designing a system of specially selected tasks to improve the training of future teachers of a digital school. Research methods. The most important idea is the acquisition of new knowledge by creation and solving tasks. The solution of the system of educational, specially designed tasks supports the implementation of the provisions of the system-activity approach to learning. The pedagogical experiment involved 120 students of specialty 44.03.01 Pedagogical education (two training profiles, bachelor's degree level), Vyatka State University, Kirov, Russia Federation. Statistical verification of the obtained results was made using Fisher's criterion (angular transformation). Results. Students of the experimental group were involved in practical activities to design their own tasks on the example of studying the theory and methods of teaching Informatics (situational-motivational; support; border): self-determination of the plot, the development directions of intensification and extensification. Statistically significant differences were revealed between the experimental and control groups in terms of the level of professional training φcrit< φemp(1.64 < 2.558). In conclusion, the authors generalized the features of the organization of practical activity for the development of a system of own tasks for a digital school: the choice of the first task, the use of information sources of various nature, learning with and without a computer, group discussion of a result, resolving contradictions, "ignorance-knowledge-understanding-skill-proficiency", work in conditions of uncertainty, etc. © 2021 LLC Ecological Help.

Influence of geological and geochemical conditions of deposits formation on the composition and properties of hydrocarbon fluids (on the example of Bovanenkovo oil and gas condensate field)

The article provides an analysis of the variability of the composition of hydrocarbon fluids from the Bovanenkovo field (Yamal, Western Siberia) in order to better understand the geological processes that led to the formation of this field and the reformation of the composition of fluids in the layers of this field. It is shown that geochemical information on the composition and properties of oil, condensate and gas allows to “reconstruct” the geological stages of the formation of deposits in their modern form. The data on the properties of fluids, group and molecular composition of the light and middle parts of oils and condensates of various layers are given. Differences in the composition of hydrocarbons from different reservoirs of the field, the relationship of the composition of fluids with oil deposits and superimposed geological reorganizations in the Yamal area already formed were demonstrated. In terms of composition, three groups of oils were identified: residual, whose composition was formed as a result of the migration of relatively low-molecular components, light oils with a high content of paraffins and light (low-paraffinic) oils and condensates. It is shown that differences in the composition of oils are due both to the composition of the original organic matter for them and to migration processes after the formation of accumulations of hydrocarbon fluids

Unspecified encephalitis in HIV-infected patients: Clinical and postmortem evaluation [Энцефалиты неясной этиологии у больных ВИЧ-инфекцией: клиническая и патологоанатомическая расшифровка]

Background. The search for an aetiology of central nervous system (CNS) lesions In HIV patients can be extremely challenging. Aim. To establish the nature and character of CNS lesion according to the data of pathological examination of deceased HIV-patients who had an antemortem clinical diagnosis of unspecified encephalitis. Materials and methods. We analysed clinical and laboratory data of 225 HIV-patients admitted to the ICU at the Infectious Clinical Hospital №2 (Moscow, 2018). The principal diagnosis was unspecified encephalitis characterized by cerebral oedema. Had died 183 (67.9%) patients. We conducted pathological examination in 43 (23.5%). Results. CNS lesions occurred in 331 patients (58.8% of 563 ICU). The antemortem diagnosis established were as follows: 12.1% - toxoplasmosis; 6.6% - HIV-encephalitis; 5.1% - CNS lymphoma; 3.6% - cryptococcal meningoencephalitis; 3.0% - cytomegaloviral diseases; 2.1% - progressive multifocal leukoencephalopathy. The cause of the pathology remained unidentified in 225 patients (68% with CNS lesions). Majority of patients were ART-naive. Post-mortem verification was conducted in 29 (67.4%) deceased patients, of which HIV-encephalitis - 34.5%, toxoplasmosis - 10.3%, progressive multifocal leukoencephalopathy - 3.4%. The nature of brain damage in the remaining 20.7% cases was not established even after post-mortem investigation. Productive lepto-meningitis - 8 (27.6%), indicating a prolonged duration of the inflammatory process. In the brain 48.1% patients with subacute and productive changes, had a pre-hospital time of more than 30 days, in contrast to 11.1% of patients who had acute pathological processes in the CNS (p<0.05). Autopsy didn't reveal any inflammatory changes in the brain in 14 (32.6%) patients, though cerebral oedema - 93.3%, haemorrhagic syndrome - 60% cases. Conclusion. Accurate retrospective identification of the aetiology of CNS lesions combined with assessing in vivo characterisation of the pathological process plays an essential role in subsequent formation of diagnostic approaches in pathologies of the CNS in HIV-patients. © 2021 Consilium Medikum.

Strzeleckia major n. g., n. sp. and S. minor n. sp. (Digenea: Hasstilesiidae) from Antechinus swainsonii (Marsupialia: Dasyuridae) in Australia

Strzeleckia major n. g., n. sp. and S. minor n. sp. are described from the dusky antechinus Antechinus swainsonii (Marsupialia: Dasyuridae) from the Kosciusko National Park in southern New South Wales, Australia. The two species were found together in the same individual host animals but occupy different sites in the intestine. The new genus is placed within the Hasstilesiidae, where it differs from the only other genus, Hasstilesia, by being more elongate and in having larger suckers, tandem testes, the ovary between rather than opposite the testes, and in having the caeca not reaching the posterior end of the body. It is suggested that the life-cycles of these species are similar to those of other hasstilesiids. Pupillid snails may act as sole intermediate hosts
