Abstract

The subject of the research is the methodological foundations of the effective organization of state policy to stimulate scientific and technical activities and the introduction of innovations into the production processes of the real sector of the economy. The purpose of the study is to identify weaknesses in the state research and innovation sphere, formulate proposals for solving the problem of low productivity of the national economy. Results of work. Comparative analysis, logical–structural, analytical and systemic. The field of application of results. Economics and management of the national economy, methods and mechanisms of regulation of economic processes and their effectiveness. Conclusions. The system of state regulation of the scientific and innovative sphere in the Ukrainian economy has been created. It has legislative support, relevant executive authorities, but works with low efficiency. We need a transition to strategic planning of the country's development. It is also necessary to ensure long–term (more than 5 years) macroeconomic stability, full–fledged budget financing of science and innovation (from 2% of GDP), reporting and control of budget spending, a new level of program–targeted planning for the development of productive forces and the real sector of the economy, the formation of state demand for innovation for industry.

Abstract

Purpose. The aim of the article is to increase the efficiency of linear pulse electrodynamic type converter (LPEC) when operating in high-speed and force modes by reducing the amplitude of the recoil force by exciting its windings with a series of pulses from the capacitive energy storage (CES). Methodology. Using the LPEC mathematical model, in which the equations describing the interconnected electrical, magnetic, mechanical and thermal processes are presented in a recursive form, the electrodynamic and electromechanical characteristics of LPEC are simulated by excitation by a single and a series of pulses from CES sections. Results. It was found that when a single pulse is excited by an LPEC operating in a high-speed mode, in which the armature accelerates the actuator, compared with the force mode in which the armature is inhibited, the current amplitude in the windings decreases by 7.5 %, and the amplitudes of electrodynamic force (EDF) – by 21.8 %, impulse values of EDF – by 27.1 %. In this case, the armature winding with the actuating element accelerates to a speed of 7.1 m/s. When excited by a series of pulses from the same sections of the CES during LPEC operation in the force mode, the amplitudes of the current pulses and the EDF are practically unchanged, and when operating in high-speed mode, the amplitudes of the currents and the EDF gradually decrease. Both in power and in high-speed operating modes, an increase in the number of excitation pulses while conserving the energy of the CES leads to a decrease in the main indicators of LPEC. But by reducing the amplitude of the EDF, which manifests itself as a recoil force, the efficiency of LPEC increases. Originality. It is shown that the excitation of LPEC by a series of pulses increases the efficiency of LPEC when operating in high-speed and power modes, providing a minimum amplitude of the EDF, which determines the recoil force acting on the inductor winding. Practical value. For LPEC operating in high-speed mode, it is proposed to reduce the maximum current amplitudes and EDF due to the sequential increase in capacitances of sections of the CES, forming a series of excitation pulses. For LPEC, operating in force mode, it is advisable to use the same capacities of all sections of the CES., Представлена математическая модель линейного импульсного преобразователя электродинамического типа (ЛИПЭТ), в которой решения уравнений, описывающих взаимосвязанные электрические, магнитные, механические и тепловые процессы, представлены в рекуррентном виде. Исследованы электромеханические и электродинамические характеристики ЛИПЭТ при работе в скоростном режиме, обеспечивающем ускорение обмотки якоря с исполнительным элементом, и в силовом режиме, когда обмотка якоря заторможена. Показано, что при возбуждении одиночным импульсом ЛИПЭТ, работающего в скоростном режиме, по сравнению с силовым режимом происходит уменьшение амплитуды тока в обмотках на 7,5 %, амплитуды электродинамических усилий (ЭДУ) – на 21,8 %, значения импульса ЭДУ – на 27,1 %. При этом обмотка якоря с исполнительным элементом разгоняется до скорости 7,1 м/с. При возбуждении серией импульсов от одинаковых секций емкостного накопителя энергии (ЕНЭ) и работе ЛИПЭТ в силовом режиме амплитуды импульсов тока и ЭДУ практически неизменны, а при работе в скоростном режиме происходит последовательное уменьшение амплитуд токов и ЭДУ. Увеличение количества импульсов возбуждения при сохранении энергии ЕНЭ приводит к уменьшению основных показателей ЛИПЭТ. Но за счет уменьшения амплитуды ЭДУ, которая проявляется как сила отдачи, эффективность ЛИПЭТ увеличивается. Для ЛИПЭТ, работающего в скоростном режиме, предложено уменьшение максимальных амплитуд тока и ЭДУ за счет последовательного увеличения емкостей секций ЕНЭ, формирующих серии импульсов возбуждения. Для ЛИПЭТ, работающего в силовом режиме, целесообразно использовать одинаковые емкости всех секций ЕНЭ.

Abstract

The possibilities for performing ureterocalicostomy significantly depend on the anatomy of the lower group of cups, which has not been examined yet from the point of view of this operation. The study included 115 patients who underwent multispiral computed tomography for various indications. The number of small cups of the lower group ranged from 1 to 5 (2.5 on average). We identified four main options for localizing renal cups in the region of the lower pole: I – one of the cups is localized in front, and the second along the vertical axis of the kidney (n = 13 / 11.3%); II – one of the cups is localized in front, and the second in the back (n = 35 / 30.4%); III – there is only one cup suitable for ureterocalicostomy, located along the vertical axis of the kidney (n = 18 / 15.7%); IV – one of the cups is localized at the back, and the second along the vertical axis of the kidney (n = 49 / 42.6%). The probability of damage to two cups with transverse resection of the kidney is 29.6%, while with oblique resection of kidney it is 12.2%. Information about the number of renal cups in the lower group and their spatial localization plays an important role in planning ureterocalicostomy. The proposed anatomical classification of cup anatomy allows choosing the type of renal resection in a particular patient and avoiding damage to adjacent cup structures.

В исследование были включены 115 пациентов, которым проводилась мультиспиральная компьютерная томография (МСКТ) по различным показаниям. Количество малых чашек нижней группы варьировало от 1 до 5 (в среднем 2,5). Мы выделили четыре основных варианта локализации почечных чашек в области нижнего полюса: I – одна из чашек локализуется спереди, а вторая по ходу вертикальной оси почки (n=13/11,3%); II – одна из чашек локализуется спереди, а вторая сзади (n=35/30,4%); III - имеется только одна чашка, которая подходит для уретерокаликоанастомоза, располагающаяся по ходу вертикальной оси почки (n=18/15,7%); IV - одна из чашек локализуется сзади, а вторая по ходу вертикальной оси почки (n=49/42,6%). Вероятность повреждения двух чашек при поперечной резекции почки составляет 29,6% , тогда как при косой резекции – 12,2%. Информация о количестве почечных чашек нижней группы и их пространственной локализации играет важную роль при планировании уретерокаликоанастомоза. Предложенная анатомическая классификация чашечной анатомии позволяет легко выбрать вид почечной резекции у конкретного пациента и избежать повреждения соседних чашечных структур., Можливості здійснення уретерокалікоанастомоза істотно залежать від анатомії нижньої групи чашок, яка ще не розглядалася з точки зору цієї операції. До дослідження було включено 115 па-цієнтів, яким проводилася мультиспіральна комп’ютерна томографія (МСКТ) за різними показниками. Кількість малих чашок нижньої групи варіювала від 1 до 5 (в середньому 2,5). Ми визначили чотири основні варіанти локалізації ниркових чашок у ділянці нижнього полюса: I – одна з чашок локалізується спереду, а друга по ходу вертикальної вісі нирки (n=13, 11,3%); II – одна з чашок локалізується спереду, а друга ззаду (n=35, 30,4%); III – є лише одна чашка, яка підходить для уретерокалікоанастомоза, що розташовується по ходу вертикальної вісі нирки (n=18, 15,7%); IV – одна з чашок локалізується ззаду, а друга по ходу вертикальної вісі нирки (n=49, 42,6%). Імовірність ушкодження двох чашок при поперечнії резекції нирки становить 29,6%, тоді як при косій резекції – 12,2%. Інформація щодо кількості ниркових чашок нижньої групи і їх просторової локалізації відіграє важливу роль при плануванні уретерокалікоанастомоза. Запропонована анатомічна класифікація чашкової анатомії дозволяє легко обрати вид ниркової резекції у конкретного пацієнта і уникнути пошкодження сусідніх чашкових структур.

Kharkov National Medical University, Kharkov, Ukraine Summary Organ Preservation Surgery (OPS) is a viable and safe treatment for large kidney tumors. For large tumors (T2 or more), with OX, renal function is better preserved and therefore kidney resection has advantages over nephrectomy. Given that loss of kidney function can cause an increased risk of severe cardiovascular disease and mortality, OPS can have significant advantages over nephrectomy in terms of overall survival. OPS has a higher potential risk of peri-and postoperative complications than with nephrectomy due to the greater complexity of the operation, which requires a balanced approach in assessing the possible risks and advantages of the operation. However, the high risk of complications justifies itself, given similar oncological results and better preservation of renal function. OPS in patients with stage T2 and more should be used in well-selected patients, taking into account the characteristics of the tumor and the technical capabilities of the surgeon to reduce the number of complications. Based on this, further promising randomized trials are needed to evaluate the role of OPS in the treatment of large tumors. Key words: kidney tumors; organ-sparing surgery; radical nephrectomy.

Abstract

The subject of the study is the methodological issues of assessing capital profitability when planning the price or tariff for goods or services of a state–owned enterprise operating in a limited monopoly. The aim of the study is to propose a methodology for calculating the standard rate of return on production capital of state enterprises. Methods of research. In the work, general scientific and special methods were used: comparative analysis, assessment of capital assets, calculation of profitability of production costs, assessment of the effectiveness of capital investments. Results of the work. The article analyzes and selects methods for calculating profit in the price of products, makes practical calculations and proposes a generalizing method for planning return on capital in the price of products in the case of a state monopoly on the market. Application of results. Economics and management of the national economy, in terms of state systems and mechanisms for managing the economy at the sectoral, intersectional and regional levels. Conclusions. The public sector makes up one tenth of the national economy. A significant part of state enterprises operates in a limited monopoly. When pricing, profit is laid according to the rate of return on capital. To determine this standard, six methods and a method for generalizing potential profitability are proposed. Using a set of methods allows you to avoid overstating profit in price, which is typical in a monopoly.

Abstract

Coagulopathy always accompanies blood loss, and its transformation into disseminated intravascular coagulation syndrome (DIC) is associated with increased morbidity and mortality.Objective: to characterize the features of the development and course of DIC during bleeding, as well as identify the main predictors of its formation during surgical interventions in children with oncological diseases.Material and Methods. A retrospective study of children under 18 years of age with oncological pathology who received surgical treatment for the period from 2017 to 2019 years. Children who received blood transfusion and hemostatic therapy with intraoperative bleeding were selected. The resulting cohort (n=207) was divided into two groups using the modified ISTH assessment system: children with DIC (n=59), without DIC (n=148). Demographic, clinical, and laboratory factors were compared between groups. The final model of multivariate logistic regression included signs that were before the development of DIC on the second day after the operation and were selected as a result of univariate analysis (P<0.05), had less than 10% missing data and were clinically plausible. The prediction accuracy of the multivariate model was checked by analyzing the area under the ROC curve.Results. DIC was found to develop often in children with cancer during surgical operations in the retroperitoneal space (OR=2.09 [1.07; 4.05]; P=0.03) and liver (OR=3.86 [1.72; 8.67]; P=0.001). Multiple organ failure (MOF) was more severe and was represented by pulmonary, hepatic and renal failure in the group with identified DIC. The development of MOF was accompanied by a decrease in tissue perfusion and an increase in D-dimer. The probability of detecting acute thrombosis after surgery was 4.5 times higher in the group of patients with DIC than in the group without DIC (OR=4.5 [1.4; 14.3]; P=0.01). 90-daily survival was 84.41±6.49% [71.69%; 97.13%] in the group of patients with DIC, and 96.22±3.12 [90.1%, Кровопотере всегда сопутствует коагулопатия, а ее трансформация в синдром диссеминированного внутрисосудистого свертывания (ДВС-синдром) связана с повышенным уровнем заболеваемости и смертности.Цель исследования. Охарактеризовать особенности развития и течения ДВС-синдрома при кровотечениях, а также выявить основные предикторы его формирования при оперативных вмешательствах у детей с онкологическими заболеваниями.Материалы и методы. Ретроспективное исследование у детей в возрасте до 18 лет с онкологическими заболеваниями, получавших хирургическое лечение в период с 2017 по 2019 годы. Отобрали детей, получавших гемотрансфузии и гемостатическую терапию при интраоперационном кровотечение. Полученную когорту (n=207) разделили на две группы с использованием модифицированной системы оценки ISTH: дети с ДВС-синдромом (n=59), без ДВС-синдрома (n=148). Провели сравнение демографических, клинических и лабораторных факторов между группами. В окончательную модель многофакторной логистической регрессии включили признаки, которые были до развития ДВС-син-дрома на 2-е сутки после операции и были отобраны в результате однофакторного анализа (p<0,05), имели менее 10% пропущенных данных и были клинически правдоподобными. Точность прогнозирования многофакторной модели проверили по анализу площади под кривой ROC.Результаты. Установили, что ДВС-синдром у детей с онкологическими заболеваниями часто развивается при операциях в области забрюшинного пространства (OR=2,09 [1,07; 4,05]; p=0,03) и печени (OR=3,86 [1,72; 8,67]; p=0,001). Полиорганная недостаточность (ПОН) была более тяжелой и была представлена легочной, печеночной и почечной недостаточностью в группе с выявленным ДВС-синдро-мом. Развитие ПОН сопровождалось снижением показателей тканевой перфузии и ростом D-димера. Вероятность выявления острого тромбоза после операции была в 4,5 раза выше в группе пациентов с ДВС-синдромом, чем в группе без ДВС-синдрома (OR=4,5 [1,4; 14,3]; p=0,01). 90-дневная выживаемость составила в группе

Abstract

We have developed a simple gold-catalyzed procedure for the synthesis of substituted and modifiable azulenes. The azulenes are formed either by the dimerization of push-pull diarylalkynes bearing a fluorine atom in ortho or para position or by the dimerization of a symmetric electron-rich diarylalkyne. In the presence of a cationic gold catalyst, the two alkynes can form a highly reactive vinyl cation. Trapping of this high-energy intermediate by an appropriate aryl unit then delivers substituted azulenes in a single step and in a perfect atom economy.

Abstract

A new modification of the TEM-horn antenna has been developed for ground-penetrating radar (GPR) applications. The antenna is based on a dielectric wedge, and thus, was named the dielectric wedge antenna. Tapering of the metal flairs has been used to match the antenna to the ground and to reduce the late-time ringing. The finite-difference time-domain model of the antenna has been created to investigate physical processes within the antenna and to optimize its performance. The dielectric wedge antenna has shown a superior (in comparison with the TEM-horn) performance by radiation in different types of the ground and has been used in a novel antenna configuration within a GPR system, which is dedicated for landmine detection. Index Terms--Finite-difference time-domain (FDTD), ground penetrating radar, TEM-horn antenna, transient antenna, ultra-wideband antenna.

Abstract

Nanostructured powders of pseudoalloys of immiscible Cu and Mo metals are prepared by highenergy ball milling (HEBM). Mechanical alloying in an Activator-2S planetary ball mill for 60 min provides a uniform distribution of refractory Mo particles in a moldable Cu matrix on submicron and nanoscopic levels. Nanostructured Cu–Mo powders are consolidated by spark plasma sintering (SPS) in a temperature range of 700–950°C at a pressure of 50 MPa for 10 min. The effect of preparation conditions on the microstructure, crystal structure, and properties (density, hardness, electric resistivity) of the nanostructured Cu–Mo pseudoalloys is studied. It is shown that a combination of HEBM and SPS provides the formation of a high-density (97%) nanostructured consolidated Cu–Mo composite with a hardness of 3.68–3.88 GPa and an electric resistivity of 6.1–6.2 μΩ cm; these parameters made the composite promising for use as an electric-contact material.
