https://doi.org/10.31174/SEND-NT2018-179VI21-02
Abstract. In paper presents the results of studying the adaptability of varieties of salad chicory witluff Caesar, Voevoda, Konus and Leonardo. The influence of growing conditions on phenological and biometric indices, yield and quality of fresh greens has been proved. It has been established that the biological characteristics of the varieties influence the timing of the passage of the phenological phases, the growth and development of the plants of the salad of chicory witluf. Depending on the variety, the plants developed almost simultaneously, but there were certain differences in the onset of the main phenological phases and the difference was two to four days. The increase in the leaf mass has been active since the beginning of June and reached high rates in late September – early October before harvesting of root crops. The number of leaves on the plants of salad chicory witloof changed during the period of vegetation and 30 days after shoots was almost the same in all varieties of 3-4 pcs./rst, and at the end of the vegetation reached 18-25 pcs./rst. It was established that the total area of leaves of salad chicory witloof before harvest would be more in the Voyevoda variety – 22,1 thousand m2/ha and significantly exceeded the control. A little less this indicator was for the varieties Konus and Leonardo 15,9-17,2 thousand m2/ha respectively. The end of the formation of root crops was observed in the II-III decades of October. In the control of Caesar, the phase advocated earlier – on October 15, and later on the Conus variety on October 24th. The technical maturi- ty of the varieties of Voevoda and Leonardo came a little earlier (172-177 days, respectively), due to somewhat better growth and development of plants in general. The technical maturity of plants in the Conus variety was observed later on – for 181 days. It wasproved that in the conditions of the Right-bank Forest-steppe of Ukraine in chernozem podzolennymi on the yield of root crops among the studied varieties was the best grade Voyevoda and Leonardo, the high productivity of coconuts after the distillation was a variety of salad chicory witluff Voevoda. The conducted researches have shown that in the conditions of the Right-bank Forest- steppe Ukraine on podzolized black soil, suitable for cultivating investigated varieties of chicory salad are suitable. According to the yield of varieties of salad of chicory witloof from high-yielding to less productive one can be placed in the following order: Voevoda, Leonardo, Konus, Caesar. According to the results of the research, we recommend to grow chicory witloof of varieties Leonardo and Voevoda with a yield of 15,0-15,8 t / ha, which will allow additionally to obtain 1,3 t / ha with high qualitative indicators.
Keywords: chicory salad, vitluf, adaptability, variety, yield, quality.

Abstract. The article states that the level of soil contamination with radionuclides don’t exceed the critical standards and is actually 20-100 less in comparison with 90 years of the XX century. It has been proven that contamination with radionuclides depends on the structure and physical characteristics of the soil, as well as its acidity, the depth of sampling, and the like. It is proposed to continue systematic monitoring and control over the level of radioactive contamination of soil, vegetables and potatoes in order to reduce the content of radionuclides. The data of biometric parameters of celery and spinach plants under the influence of hydrogel in the form of gel, tablets and granules are given. In particular, the granules and gel had a greater influence on the plant heights and the diameter of the cuttings in Monarch, Anita and Pascal varieties, whereas a significant increase in leaf area occurred under the action of tablets and granules. It was found that the use of the gel significantly increased the mass of the aboveground part of the plants. High commercial yield was obtained with the use of gel: celery of the Anita variety – 43.5 t/ha, which in addition to the control yields 10.8 t/ha, Pascal – 39.8 t/ha (+7.1 t / ha), spinach of the Monarch variety – 36.8 t/ha (+4.1 t/ha). The indices of the chemical composition of commercial greens of spinach and celery varieties are determined depending on the use of various forms of hydrogel. It was estab- lished that different forms of hydrogel had different effects on the change in the biochemical composition of commercial greens of varieties.
Keywords: soil, celery, spinach, hydrogel, yield, quality.

https://doi.org/10.31174/SEND-NT2018-179VI21-06
Abstract. The effect of alimentary caffeine load on the level of dehydroepiandrosterone sulfate (DHEA-S) in the blood serum of rats of different sexes of five age groups was studied. It was found that under the influence of caffeine, the level of the hormone significantly decreased in males of juvenile age, females of young, mature and prescient age. Influence of caffeine load in males of young and females of juvenile age did not cause significant changes. But in the old age, the level of DHEA-S under physiological conditions was the lowest among all age groups, and under the influence of caffeine, its level increased significantly. In males of senile age, the value of the hormone level increased by 2,75 times with respect to the control group of this age.

https://doi.org/10.31174/SEND-NT2018-179VI21-07
Abstract. The registration and analysis of the dynamics of the absolute power of the Electric Hypothalamus Test (EGtG) waves and the spectral capacities (%) of the EGtG frequency components normalized to the total power of the bioelectric activity of the ergotropic zone of hypothalamus of female rats of different age groups was made. Female rats of juvenile age were characterized by an almost equal distribu-tion between high-frequency and low-frequency oscillations. The predominance of high-frequency oscillations among the whole EGtG spectral composition in young and mature female rats was established, which was accompanied by desynchronization mechanisms. Slowwave synchronization processes influenced the indices of bioelectric activity of the ergotropic zone of hypothalamus in presenile female rats.

Abstract. The publication describes a method of comparing surfaces given by triangulation models, which is proposed to be used for solving tasks of planning the for construction territory. The proposed approach uses digital elevation model constructed within the specified limits on the basis of the triangulation method. The creation of a combined triangulation grid of both surfaces allows interpolation of the functions of determining the height markings based on the localizationof triangulations in one another. Comparison of functions on separate faces of combined triangulation allows us to determine the difference between surfaces. The method is proposed to be used to compare two digital elevation models − “As project” and “Аs built”, for determination of two surfaces intersection and for calculation of the earthworks volumes on the construction site.

https://doi.org/10.31174/SEND-NT2018-179VI21-11
Summary. Splenectomy (SE) in hematologic patients is accompanied by an increased risk due to the presence of a hemostasis violation in most cases. All this determines the search for more favorable methods of surgical intervention in patients with diseases of the blood system. The purpose of the study is to improve the results of surgical treatment of patients with blood system diseases by planning the method of splenectomy. The work was performed on the basis of a comprehensive clinical-laboratory and instrumental examination of 102 patients with various diseases of the blood system that needed surgical treatment. In addition to laboratory diagnosis, special attention was given to the anamnesis: duration of the disease, hormonal therapy; instrumental research methods: ultrasound of the abdominal cavity and CT, as well as nosologies. A harmonic scalpel was used to mobilize the spleen. The EndoGIA-30 stapler (AutoSuture) was used to treat the vascular pedicle. Analysis of the results of SE in patients with hematological profile showed that the choice of surgical access depends on many factors which can be set before operation by dint of ultrasound and CT. There were no conversion cases, which could be explained by the possibility of objective preoperative planning, as a result of which in cases of laparoscopic adverse events, a decision was made to perform open type of SE. The absence of complications and fatal cases at SE in hematologic patients shows the efficacy of the use of harmonic scalpel and EndoGIA-30 (AutoSuture) staplers to mobilize the spleen. The use of ultrasound and CT plays an important role in planning the method of spleenectomy, which avoids cases of conversion. Simultaneous use of harmonic scalpel and Autosuture staplers for performing SE helps to avoid complications.

https://doi.org/10.31174/SEND-NT2018-179VI21-17
Abstract. Discusses the various modes of motion of an аutonomous underwater vehicle: horizontal, vertical, under the action of propulsion Analyses the behavior of the vehicle in an aqueous environment and methods of its stabilization. Since the vehicle can be designed as well- streamlined body for movement with large relative velocities and may be slow-moving platform carrying equipment for yourself that is open to water, the approaches to this task are different. Often working vehicles are required increased maneuverability and propulsion recedes into the background. Hence are formed the approaches to the choice of power and propulsion and steering complex. With regard to calculations of statics and dynamics, there are features that differentiate the underwater vehicle from conventional floating objects. In most cases, to achieve high stability fails. It is necessary to provide or excessive volume inside the pressure hull, not used for equipment or additional buoyancy of a lightweight material, placed outside the hull of the vehicle. The possibility of lowering the center of gravity by movement of equipment is also limited. In this regard, there is the problem with the opposition to the action of external forces in static and in dynamics, although for underwater vehicle the concept of tipping is becoming more content. The technique of a choice the metacentric height and area of the stabilizing of the vehicle, the possibility of regulation of stability and its standartisation. The analysis of experimental data of variants of design realization of models and natural objects indicates that: The greatest influence on the choice of the area of the stabilizers is having the speed of operation of the apparatus, and to a lesser extent, the external form and the ratio of the main dimensions of L/H or L/D. To estimate the stability of the initial design stage, one can use the dependencies (2) (8), which with an accuracy of 7-10% allow to determine the required value of the metacentric height or the area of the stabilizer in the early design stages. With the increase in the size of the device expands the possibility of variations in the position of the centers of gravity and magnitude. For AUV with a well-streamlined body shape, the area of stabilizing devices depends mainly on the speed and weakly on the relative body udineniya asymmetrically bringing kx to 2%.
