https://doi.org/10.31174/SEND-NT2020-244VIII30-02
Abstract. The external morphology and micromorphology of the flower in Tulbaghia violacea were studied. Light microscopy was used for examination. Our approach allows us to differentiate species and genera by location and presence of different vertical zones in gynoecium and especially septal nectaries. The gynoecium of T. violacea consists of synascidiate, symplicate, hemisymplicate and asymplicate vertical zones. Common septal nectary with three nectary splits throughout the ovary is available in T. violacea gynoecium.
Keywords: ovary, gynoecium, septal nectary, flower morphology.

https://doi.org/10.31174/SEND-NT2020-244VIII30-03
Abstract. As one of the promising methods in the study of processes of change in the aquatic ecosystems state under the anthropogenic and man-made load action, the application of the probabilistic-automatic modeling method is proposed in the paper. This approach makes it possible to determine the processes mechanisms of system transition from state to state, as well as to determine the characteristics of this system in each state, taking into account uncertainties, and to analyze ecological capacity and determine the vulnerability of aquatic ecosystems in discrete moment times for a particular region.
Keywords: aquatic ecosystem, man-caused load, ecological capacity, vulnerability coefficient, probabilistic-automatic modeling.

https://doi.org/10.31174/SEND-NT2020-244VIII30-04
Abstract. The results of the study of axisymmetric bending of round continuous plates on a variable elastic foundation are presented. The finite element method used in the LIRA-SAPR software is used as the most universal of the numerical methods. Eight options for calculating a continuous round plate (slab) under two fixing conditions and two different laws of changing the coefficient of subgrade resistance are considered. In all cases, the results completely coincide with the known results of bending plates that do not have an elastic foundation and in the case when this foundation exists and its resistance is constant. It is noted that the discrepancy here is very slight – in the third significant digit after the decimal point for deflection at simple support and in the second for moments. With fixing, deflections and moments also differ from the corresponding values of the known solutions in the second significant digit after the decimal point. As for the elastic foundation, coefficient of subgrade resistance of which varies according to the law of a curved parabola, there are no data for comparison; need an alternative method that will allow you to perform similar calculations. To date, such a method (analytical) has already been developed by the authors of the paper. Its concept and comparison with the results of finite element analysis will be the subject of our next publication in the field of calculation of plates on a variable elastic foundation.
Keywords: plate, elastic foundation, Winkler foundation, coefficient of subgrade resistance, finite element method, LIRA-SAPR.

https://doi.org/10.31174/SEND-NT2020-244VIII30-05
Abstract. The geospatial organization of the region’s tourist resources is closely connected with its recreational and tourist potential, as well as the configuration of modern tourist flows. It should be noted that Vinnytsia region does not belong to the regions of Ukraine that have a pronounced tourist specialization, but its potential for long-term development of the tourism sector is quite high. This necessitates the development of scientifically sound approaches to optimizing the use of recreational and tourist potential of the region. Therefore, we have developed a map showing the main tourist destinations in the region and attempted tourist zoning.
Keywords: tourist subregions, map, point estimation, tourist zoning, analysis.

https://doi.org/10.31174/SEND-NT2020-244VIII30-08
Abstract. The results of numerical modeling of the “tooth – endodonto-endosseous implant – bone” system using standard collapsible implants, small diameter, and surgical instrumental kits are presented. The study of the stress-strain state of all components of the system by the finite element method in the ANSYS program has been carried out. The dentoalveolar segment was investigated with the following parameters: length of the tooth root – 14.25 mm; root resection – by 1/3; implant length – 13.0 mm; the depth of immersion in the spongy bone – 2mm; implant diameter (variable value) – 2.9; 3.0; 3.2 mm. The external load was taken equal to 200 N, and applied at an angle of 1250. The constructed model differs significantly from that given in the literature. In its construction, the “bottom-up” method of solid modeling was used. The geometry of a bone fragment and teeth is given by a set of cross-sections in the form of inhomogeneous rational B-splines with variable height dimensions and location of centers. Stresses and displacements in all elements of the system are determined. Calculations have shown that stresses in the tooth, cortical and cancellous bone are practically independent of the implant diameter, but decrease with an increase in its diameter.

https://doi.org/10.31174/SEND-NT2020-244VIII30-09
Abstract. Arterial hypertension is one of the main causes of cardiovascular mortality in the world and affects almost 25% of the adult popu- lation. The aim was to determine the blood pressure daily profile depending on the type of salt-sensitivity in patients with stage II arterial hypertension. Materials and methods. 120 individuals aged 30-75 years with stage II arterial hypertension and 50 practically healthy individuals (control group) were enrolled to the study. Weinberger M. N. method was used to determine the type of salt-sensitivity. The essence of this method is to stick to a high-salt diet during 5 days with the salt consumption of 15 g per day (250 mmol sodium), with a further re- striction on salt intake to 2 g per day (up to 50 mmol sodium) for 5 days (low-salt diet). The systolic blood pressure decrease by more than 10 mm Hg after switching from a high-salt to low-salt diets. Level of the blood pressure was the diagnostic criterion for salt-sensitivity. Patients were classified as salt-resistant included patients whose systolic blood pressure did not decrease by more than 10 mm Hg during the study and individuals with a paradoxical reaction to the change in salt load and a increase in systolic blood pressure during the switching to a low- salt diet. Daily blood pressure monitoring was performed according to the standard protocol. Results. 42.5% of salt-sensitive and 47.5% of salt-resistant patients were identified. The blood pressure daily profile distribution showed that 76.5% of «non-dippers» and 15.6% of «night- peakers» were among salt-sensitive, and 73.7% of «dippers» and 19.3% of «non-dippers» – among salt-resistant patients. Salt-sensitive patients have nighttime blood pressure dipping more than 2 times less than control (p < 0.001). This matches to the type of «non-dippers» daily profile. This is prognostically unfavorable. Salt-sensitive patients have the 24-hour mean variability systolic and diastolic blood pres- sure values are significantly higher than in the other groups. The morning increase in blood pressure analysis revealed that values in both groups remained unchanged and corresponded to control group. Salt-sensitive patients had increased 24-hour mean rate of morning increase in systolic blood pressure, systolic blood pressure time index, and blood pressure variability values in comparison with salt-resistant patients. Conclusions. Salt-sensitive patients are characterized by a predominance of the «non-dippers» and «night-pеаkers», enlarged rate of morning increase in blood pressure, increased blood pressure variability, and the lowest degree of nighttime blood pressure dipping, which is prognos- tically unfavorable for the arterial hypertension course. Salt-resistant patients have a favorable blood pressure daily profile – «dippers» and the reference values of daily profile parameters.
Keywords: arterial hypertension, salt-sensitivity, blood pressure daily profile.

https://doi.org/10.31174/SEND-NT2020-244VIII30-13
Abstract. Due to the need to transport various special, construction, agricultural and other machinery, large tanks, industrial equipment, etc., the transportation of heavy oversized cargo has been growing in recent years. The specificity of oversized and heavy transportation lies in many points, without which timely and safe delivery of goods to the destination is not possible. An important point (element) of such transportation is to take into account the strength and load-bearing capacity of bridges and road structures (road clothing) and the choice of appropriate specialized rolling stock. This article reveals the following aspects of this topic: definition of basic concepts, regulatory constraints, features of preparation and process of transportation of large and especially heavy goods, route selection, rules of transportation of goods by road, as well as documentation of cargo transportation. It should be noted that special literature on the theory related to this topic is not enough. The article presents the authors ’own experience in solving such problems at transport infrastructure facilities in Ukraine, taking into account practical material and information available on the pages of transport companies. As the requirements for transportation are constantly supplemented and changed, these sources are useful in the analysis of information related to the transportation of oversized and heavy cargo.
