Development of University Students’ Motivation with the Help of E-learning

The relevance of the study is due to the orientation of the modern model of education to the formation of a competitive creative personality with the need of continual self-improvement and self-development. It is possible due to the high level of the learning motivation of students and the motivation to acquire a future profession. It should be emphasized that e-learning has a considerable potential in this aspect. In this regard, this article is aimed to reveal the specifics of the use of e-learning means in the development of university students motivation. The article presents a series of lessons designed to develop students’ motivation, implemented by e-learning means. We elaborated a series of webinars (“I want to be an engineer – I want to be taught!”; "Information crystals" (effective information processing techniques), "Time Management Secrets," "Kaleidoscope of discoveries", "Jolly mathematics"); chats ("The engineer of the third millennium - the future engineer, who is he?", "Physics, Chemistry for Engineers: Myth and Reality"); the virtual round table - "The heritage of the past" (about great scientists, inventions and discoveries) and others.

Atmospheric Chemistry in Giant Planets, Brown Dwarfs, and Low-Mass Dwarf Stars II. Sulfur and Phosphorus

Thermochemical equilibrium and kinetic calculations are used to model sulfur and phosphorus chemistry in giant planets, brown dwarfs, and extrasolar giant planets (EGPs). The chemical behavior of individual S- and P-bearing gases and condensates is determined as a function of pressure, temperature, and metallicity. The results are independent of particular model atmospheres and, in principle, the equilibrium composition along the pressure-temperature profile of any object can be determined. Hydrogen sulfide (H2S) is the dominant S-bearing gas throughout substellar atmospheres and approximately represents the atmospheric sulfur inventory. Silicon sulfide (SiS) is a potential tracer of weather in substellar atmospheres. Disequilibrium abundances of phosphine (PH3) approximately representative of the total atmospheric phosphorus inventory are expected to be mixed upward into the observable atmospheres of giant planets and T dwarfs. In hotter objects, several P-bearing gases (e.g., P2, PH3, PH2, PH, HCP) become increasingly important at high temperatures.Comment: 38 pages, 8 figures, accepted for Astrophysical Journa

Parameters of passive working bodies of potato digging machine

The major working housing of potato digging machines is a plowshare on which energy costs and the quality of potato digging depend. The examination aims to justify the parameters of the plowshare and the divider of the combined digging working body. The constructive scheme of a potato-digging machine with a combined digging working body, the results of theoretical studies on the substantiation of the primary parameters of the main and intermediate plowshares and the divider, are presented. A special laboratory installation was used to conduct experiments. During the experiments, dividers with different capture widths were made, and the angle of the plowshare installation to the horizon was changed. The degree of damage and loss of the tuber and the traction resistance of the plowshares were taken as evaluation criteria. The outcome of the experimental investigation to determine the parameters of the plowshare is presented. Based on theoretical studies, analytical dependencies, and mathematical models were obtained that allow determining the parameters of the plowshare and the divider of the potato digging machine. It was found that for intensive destruction of the tuberous formation with minimal energy consumption and uniform transportation, the width of the colter of the combined working housing must be 45 cm, the perspective of the plowshare razor solution 90°, the perspective of inclination of the plowshare to the skyline within 27-30°, the length of the plowshare 40 cm, the width of the divider should be 45 cm, its length 39 cm, the angle the solution is 60°, the angle of installation of the working surface to the horizon in the transversely vertical plane is 65° and the range from the toe of the intermediate plowshare to the divider is 32.6 cm

The authors showed that it is possible to quickly collect up-to-date information on the agricultural land condition using an unmanned aerial vehicle. It was noted that the use of ground control points increases the accuracy of project measurements, helps to compare the project post-processing results with the real measurements. (Research purpose) To compare the results of standard and high-precision post-processing of aerial survey data using ground control points. (Materials and methods) Aerial photography was carried out on a 1.1- hectare breeding field. The authors used DJI Matrice 200 v2 unmanned aerial vehicle with a GNSS L1/L2 receiver and a modified DJI X4S camera, five control points sized 50 × 50 centimeters and an EMLID Reach RS2 multi-frequency GNSS receiver. The results of scientific research into the use of ground control points during aerial photography were studied. (Results and discussion) It was found out that the error of georeferencing images obtained by an unmanned aerial vehicle without control points is significantly higher during the standard data processing compared to the high-precision one. The project error when using five control points is 3.9 times higher during the standard data processing. (Conclusions) It was shown that using ground control points it is possible to improve the project measurement accuracy, as well as compare the project post-processing results with the measurements on the ground. It was detected that the high-precision monitoring enables the use of fewer ground control points. It was found out that in order to obtain data with the accuracy of 2-4 centimeters in plan and height, at least 3 ground control points need to be used during the high-precision post-processing.Показали возможность оперативного сбора актуальной информации о состоянии сельскохозяйственных угодий с помощью беспилотного воздушного судна.

Prediction of clinical course in patients with diffuse coronary artery disease after coronary bypass surgery

Aim. To determine the incidence, predictors and develop a model for long-term risk stratification of ischemic events in patients with coronary artery disease after coronary bypass surgery.Material and methods. This retrospective study of the clinical course in patients with diffuse coronary artery disease (CAD) after coronary endarterectomy and bypass grafting surgery. A total of 232 patients were included, while long-term outcomes were assessed in 202 patients. Among them, complete data on clinical status were obtained from survivors (n=191). The median follow-up was 60 (interquartile range, 42; 74) months, while the minimum follow-up — 12 months, the maximum was 96 months. The primary composite endpoint reflecting the unfavorable course of CAD included coronary ischemic events (recurrent angina, myocardial infarction, repeat revascularization), while secondary endpoint — allcause mortality. The factors influencing the development of primary and secondary endpoints were studied.Results. An unfavorable CAD course was diagnosed in 39 patients (20,4%), while 11 deaths were recorded (5,4%). Univariate analysis demonstrated a significant role of prior myocardial infarction in the increase in mortality rate (p=0,029). Among the factors influencing the CAD course, no significant differences were obtained for any of them. A multivariate analysis was performed to identify a high-risk group for an unfavorable course of diffuse CAD. Independent predictors were identified, the most significant contribution of which was made by multifocal atherosclerosis (odds ratio (OR)=1,99, 95% confidence interval (CI), 0,93-4,21, p=0,072), low adherence to secondary prevention measures (OR=2,21, 95% CI, 0,86-6,89, p=0,128) and diabetes (OR=1,73, 95% CI, 0,79-3,72, p=0,162). Using the results obtained, a prognostic model with high specificity (64%) and moderate sensitivity (53%) was created.Conclusion. The highest probability of an unfavorable long-term course of diffuse CAD was noted in patients with diabetes, multifocal atherosclerosis, and low adherence to secondary prevention measures. The obtained results make it possible to identify a high-risk group in this cohort of patients, determine the reserve of secondary prevention measures and a direction of actions to improve outcomes

Гематологические показатели крупного рогатого скота при паразитарных дерматитах

The purpose of the research is study of the animal's body clinical status and changes in hematological parameters before and after treatment against sarcoptoidosis of cattle. Materials and methods. The experiment was performed on bull calves and heifers aged 6–10 months, medium finish, of 100–120 kg of body weight. The test animals were divided into three groups: two test groups and one control group of 15 animals each. Before the experiment and at 7, 14 and 21 days after treatment with acaricides, scrapings from the affected skin and blood were taken from animals of all groups for research. The first test group animals were treated with ivermectin subcutaneously at a dose of 5 ml per animal, and the second test group was treated with cydectin subcutaneously at a dose of 5 ml per animal. The control animals were not treated. Results and discussion. The conducted hematological studies found a decrease in erythrocytes and hemoglobin in sarcoptoidosis, which indicated a decrease in oxygen supply to the body, and, consequently, organs and tissues. The white blood cell differential was observed to have a noticeable decrease in monocytes and lymphocytes.Цель исследований: изучение клинического статуса организма животного, изменений гематологических показателей до применения и после лечения при саркоптоидозах крупного рогатого скота.Материалы и методы. Опыт проводили на бычках и телочках в возрасте 6–10 мес., средней упитанности, живой массой 100–120 кг. Подопытных животных разделили на три группы: две опытные и одну контрольную по 15 голов в каждой. До опыта и через 7, 14 и 21 сут после обработки акарицидными препаратами у животных всех групп брали соскобы с пораженных участков кожного покрова и кровь для исследования. Животные первой опытной группы были обработаны ивермектином подкожно в область предплечья в дозе из расчета 5 мл на животное, а второй опытной группы – цидектином подкожно в дозе из расчета 5 мл на животное в область предплечья. Животных контрольной группы не обрабатывали. Результаты и обсуждение. В процессе проведенных гематологических исследований было установлено снижение количества эритроцитов и гемоглобина при саркоптоидозах, что свидетельствовало о снижении поступления кислорода в организм, а, следовательно, и в органы и ткани. В лейкоцитарной формуле наблюдали заметное снижение числа моноцитов и лимфоцитов
