The calculation of the design parameters of a disc mill equipped with a feeder made in the form of a conical hopper is given. For shredders of the disintegrator type, it is very important to ensure the uniformity of loading of the crushed material of the working zone of active impact on particles. In addition, the most important factor is the throughput capacity of all sections of the grinding plant. The throughput should be determined by the design and technological parameters of the working chamber of the mill. Its overload can lead to a blockage of the working chamber, and insufficient throughput will negatively affect the intensity and effectiveness of the impact on the particles of the material. For example, insufficient concentration of particles in the secondary zone of the grinding chamber leads to a decrease in the efficiency of mutual abrasion. The article attempts to determine the design and technological parameters in the loading and accelerating parts of the disk mill. At the same time, it is necessary to coordinate the throughput of the disk spreader and the volumetric flow rate of the material particles flowing from the hopper. In this case, it is advisable to take into account that as a result of a rather high rotational speed and the size of the initial particles, with the wrong height of the radial blade of the spreader, material particles can roll over the radial blades, which leads to a delay of the material in the zone of the spreading disc. Therefore, it is necessary to determine the calculation formulas for finding the required height of the radial blade of the spreading disc, depending on the size of the initial particles. The formula demonstrates that the height of the separating blade depends on the particle size, the speed of rotation of the disks and the distance to the point of meeting of the particle with the radial blade.

The Family Hope Program (PKH) is a conditional cash transfer program for low-income families. The requirement is to be actively involved in education and health. The Family Hope Program in Indonesia was implemented in 2007 to alleviate poverty and prosper low-income families. The research and writing of this journal aim to determine the impact of PKH on family welfare and see if there is a reduction in poverty after the government realizes the Family Hope Program. This study uses a qualitative method with a descriptive approach. The study results indicate that the impact of PKH on beneficiary families, including the cash provided, can meet consumption or family needs and help the economy of PKH recipient families. The implementation of the program can reduce poverty in Aceh. The percentage of the poverty rate fell to 0.02%. The limitation of the research is the impact of PKH on family welfare and wants to examine whether there is a decrease in the percentage of poverty in Aceh or Aceh Barat. The practical implication of this research is to provide information to the government that PKH can improve the welfare of low-income families. The social significance is to give the government and the general public that the implementation of social assistance programs, one of which is the Family Hope Program, can reduce poverty rates in Aceh or West Aceh. The originality of the research is supported by previous research related to the author’s research study.

Published: December 2021

According to the literature data, gallbladder (GB) condition influences the course of coronary heart disease (CHD) and parameters of heart structure and function. The aim of this work was to estimate the peculiarities of heart condition in patients with CHD (acute myocardial infarction) in dependence of GB condition. We held a retrospective analysis of data of 142 patients. Results. It was revealed that in 83.7 % patients GB was changed: cholelithiasis (34.5 %), past cholecystectomy due to cholelithiasis (7.0 %), sludge and poliposis (17.6 %), bent GB body (13.4 %), neck deformations and signs of past cholecystitis (14.8 %). GB changes were accompanied by significant increase of heart rate, which was the most prominent in case of cholelithiasis, neck deformations and past cholecystitis signs. Conclusions. Pathological conditions of GB were accompanied by left ventricle dilatation, aortic distension, significant decrease of ejection fraction and systolic dysfunction, whereas after GB removal sizes of heart chambers were close to optimal values, although the systolic function did not normalize.

Published: December 2021

The treatment of non-specific chronic pleural empyema with bronchial fistulae remains one of the most relevant issues in thoracic surgery. The question about the treatment phasing of bronchial fistulae associated with chronic pleural empyema is yet to be answered. Is it reasonable to seal a bronchial fistula before or after the sanitation and obliteration of the residual pleural cavity? The choice of bronchial fistula sealing technique is also a relevant issue because, in spite of the multitude of techniques, there is still no single doctrine. The terms of traditional and minimally invasive techniques aimed at bronchial fistula sealing and pleural cavity obliteration are not defined, either. This article summarises the opinions of leading authors presented in the literature concerning the solution of this complex, life-threatening problem.

Published: December 2021

Purpose: The postmortem interval (PMI) evaluation is one of priorities while performing a forensic medical examination of corpse. To date, there is lack of information of morphological postmortem changes of some internal organs. Considering the persistent need to develop the method for a precise assessment of PMI, postmortem changes in these potentially informative organs were evaluated. The aim of study was to analyze morphological postmortem changes in prostate and uterus.

Materials and Methods: histological samples of 40 prostate tissues and 40 uterus (n=80) from corpses of deceased aged 18-75 years. Only cases with known time of death were included to study, the time of death was taken from police reports. Exclusion criteria were cases of violent death, cases of death with massive blood loss, tumors of studied internal organs, cases when diagnosis was not made by a forensic medical examiner. The PMI of studied cases ranged from 1 to 6 days. Histological slides were made with a staining by hematoxylin and eosin, x200 magnification, using Olympus ВХ41 and Olympus ВХ46 microscopes, Olympus SC50 camera. Postmortem morphological changes were evaluated by a calculation of blank spaces percentage in microscopical structures using a JS-based program. Connection between PMI and morphological changes was calculated by the Spearman’s rank correlation.

Results: the average percentage of blank spaces in uterus tissues was smaller than in prostate tissues (1,99 and 9,65 relatively). The slower growing of blank spaces was in uterus. In prostate samples, a notable increase of blank spaces was observed between 48 and 72 hours after the death. After this period, the increase slowed down and then an increase was observed again between 120 and 144 hours after the death. In uterus samples, a slight acceleration observed between 72 and 120 hours after the death and then slowing down between 120 and 144 hours after the death. Blank spaces in evaluated histological slides were increasing directly proportional to the PMI, a statistically significant interconnection was defined (p < 0.05).

Conclusions: The morphological postmortem changes in prostate and uterus were developing at certain time frames. Blank spaces percentage, in studied histological slides, were increasing directly proportional to the PMI increase, a statistically significant interconnection was defined. Therefore, the results of study show the possibility of the evaluation of a postmortem time interval by assessing such morphological changes in these organs, which could be used in forensic medical cases.

Mola hidatiforme
Authors:   , Natale Oscar Héctor
Published: December 2021

Los antiguos llamaban mola hidatiforme a una masa carnosa que se desarrollaba en el útero y que luego era expulsada; confundían por lo tanto restos placentarios detenidos, fibromas o fibromiomas, pólipos e infinidad de afecciones que traen como consecuencia un desarrollo del útero o neo-formaciones dentro o en las paredes del mismo, con lo que en realidad - luego se llamó mola hidatiforme o vesicular. Más tarde se vieron obligados a diferenciar las falsas de las verdaderas, reservando dicho nombre al desarrollo en el útero de vesículas cuya patogenia fué por mucho tiempo desconocida. Hipócrates y Galeno ya la conocían y creían que esta enfermedad se debía a "una falta de virtud en el semen" o a una menstruación super abundante basándose precisamente en este signo es que llegó a decir en una de sus obras que las mujeres atacadas de esta enfermedad tienen metrorragias y que si éstas se moderan o cesan la mujer cura o mejora sinó la metrorragia sí hace perecer; identificándola además por el desarrollo del vientre, falta de movimientos fetales y ausencia de leche en las mamas.

Seismic monitoring in the region in 2015 was carried out by a seismic network consisting of 59 stations. Digital equipment was installed at all stations in the second half of the year. The network capability was assessed by the level of seismic noise at the stations: in most of the region, the network provided registration of an earthquake from КR7.0, in the central (including the Greater Sochi region) and eastern parts of the region – КR6.0, and in some local zones with КR5.5. 2,276 earthquakes were registered, 17 earthquakes were felt in the settlements of the Caucasus. The maximum intensity VII at MSK-64 (SSI-17) scale was noted from the earthquake in the territory of Azerbaijan. The earthquake on November 3, which occurred on the platform territory within the Stavropol arch, felt IV
at MSK-64. The strongest earthquakes were recorded in the Terek-Caspian and Kura troughs and in the eastern part of the Greater Caucasus. The seismicity of the North Caucasus in 2015 in accordance with the seismicity scale "SOUS-09" was set as the "background average" for the observation period from 1962 to 2015.

We consider the character of the seismic process in the Baikal and Transbaikalia regions
in 2015. 36430 earthquakes with KR≥3 were recorded by seismic stations of permanent and temporary networks during the year due to the sharp increase of a number of seismic events at the north-east of the study region in the area of the large Muyakan seismic activation. 53 earthquakes were felt in the cities, towns and local settlements with an intensity not exceeding 6. The largest Tallaysk earthquake (KR=14.0, Mw=5.1) occurred at the North-Muya Ridge and was followed by few aftershocks. Focal mechanisms were determined for 118 seismic events from P-wave first-arrival polarities and based on seismic moment tensors inverted from the surface wave data. It has been found, that normal faults are realized in the sources of 49 % of earthquakes with the obtained focal mechanisms.

The results of seismic monitoring of the Magadan oblast, the Chukotka Autonomous okrug, and the shelves of the adjacent seas (Okhotsk, Chukchi, Bering, and East Siberian seas) are considered. There were 14 seismic stations working in the region. The new station “Gadlya” was opened on the Okhotsk sea coast. The catalog includes information about 290 earthquakes with energy classes KR=4.4–12.6. As usual, most of them (93 %) are localized in the Kolyma region. The total seismic energy released within the region’s borders was ΣЕ=4.6341012 J. According to the earthquake energy completeness map Кmin built for the region, minimal energy level of earthquakes, Кmin=5.0, is provided at two areas near the Susuman and Magadan stations. The station network can register without omissions the earthquakes with Kmin≥8 at the Okhotsk sea and Kolyma areas, with Kmin≥10.6 in the Chukotka area. In 2015 three earthquakes with intensities I=2–4 by MSK-64 scale were felt in settlements of North East of Russia. The 2015 strongest earthquake occurred on June 1 at 10h53m with KR=12.6 (MPSP=4.9), h=31 km in the Kolyma area. A maximum shaking intensity of I=4 was observed in Omsukchan settlement (∆=132 km). In March 2015 a swarm of 29 weak earthquakes with KR=6.2–9.8 occurred northeast of Talaya settlement. Epicenters of Kolyma area earthquakes were plotted on the tectonic zoning map of the Magadan region. Most earthquakes are confined to the main deep faults oriented in the northeastern and sublatitudinal directions. All hypocenters are located within the Earth's crust. The seismicity level of the North-East of Russia in 2015 according to the “SOUS09” scale was assessed as "background average" for the observation period from 1968 to 2015. Spatially, all earthquakes in the North-East of Russia are traditionally concentrated within the major seismogenic belts – Chersky, North-Okhotsk, and Trans-Beringian.

The article provides an overview and analysis of seismicity within the boundaries of the Arctic region for 2015, a description of seismic station networks, and processing methods. The catalog of earthquakes in the Arctic region was compiled on the basis of catalogs of several organizations and seismological centers. In total, 334 earthquakes are included in the earthquake catalog. Most of the earthquakes that occurred in 2015, including all the strongest earthquakes, were located within the mid-ocean ridges of Mon, Knipovich and Gakkel. In the offshore territories, most of the earthquakes were confined to the Svalbard archipelago, in particular, to the seismically active zone in the Sturfjord strait. The renewal of instrumental seismological observations in 2011 (station ZFI) on Alexandra Land Island in the Franz Josef Land archipelago made it possible to record weak earthquakes in the north of the shelf of the Barents and Kara Seas. For twelve earthquakes, the focal mechanism parameters are presented according to the Global CMT catalog.

Published: December 2021

Chips are a useful and popular product that is produced in most countries of the world. The main processes of traditional chips technology are slicing fruits and vegetables into thin slices, blanching and drying slices. Multilayer chips are formed from several layers of different materials (fruits, vegetables and seeds). For forming of such chips, it is important that the layers of different materials stick together well. Studies have shown that the material type and blanching time significantly affect the adhesion of material and loss of chips. Also, effect of compression of raw material layers on the chips loss was studied.

We investigated the heat controlled magnetic anisotropy (HCMA) in magnetic tunnel junctions with various junction sizes. We evaluated the HCMA from perpendicular magnetic anisotropy under a direct current voltage measured by the spin-torque diode technique. The maximum HCMA magnitude of 5.4 μJ (Wm)−1 was observed, and the HCMA increased with increasing diameter. Our results can be explained by a simple heat dissipation model and suggest that the in-plane heat current affects HCMA.

Published: December 2021

Environments with a climatic characteristic of semi-aridity exhibit high rainfall variability, increasing significantly as the climate changes. In this study, rainfall concentration and Spatio-temporal trends in annual and seasonal (November to March) rainfall in Botswana were analyzed. The satellite data (1958-2019) is obtained from the Southern African Science Service Centre for Climate Change and Adaptive Land Management and the Climate Toolbox. The Mann–Kendall trend test (MK), autocorrelation function (ACF), relative percentage change (RPC), precipitation concentration index (PCI), and Theil–Sen's slope estimator (β) methods were adopted for data analysis. The regions include Gaborone, Maun, Francistown, Serowe, Kasane, Tsabong, Ghanzi, and Pandamatenga. The results indicated that the magnitude of change of change of the significant downward trends in the annual rainfall was found to be -1.11 mm/year at Maun, -1.62 mm/year at Ghanzi, -0.33 mm/year at Pandamatenga, and -0.25 mm/year at Tsabong. The magnitude of change of change of the significant downward trends in the seasonal rainfall was between -0.60 mm/year at Pandamatenga and -0.19 mm/year at Tsabong. All these regions, except Ghanzi, experienced a downward trend in the rainfall distribution. This is owing to the synoptic characteristic of the below-average geopotential heights over Ghanzi. Which might exacerbate the formation of convective systems, leading to a positive rainfall trend at Ghanzi. The annual calculated PCI values are divided into three classes; PCI>10≤15, PCI>16≤20, and PCI>20. The Mann-Kendall analysis of the PCI values indicates that all the regions experienced a downward rainfall trend, implying that it is heading toward a uniform to a moderate distribution. There were distinct patterns that emerged from the Pandamatenga region, indicating a strongly irregular distribution. The regions of Kasane, Maun and Francistown, demonstrated moderate to an irregular distribution. For Gaborone and Francistown, results showed occurrences of a moderate to strongly irregular distribution.

Authors: GÖK Mustafa Güven
Published: December 2021

Metallic materials having a porosity of 70% or more are generally referred as highly porous metals. In this study, highly porous pure nickel materials were produced by powder metallurgy route. In the production process, potassium bromide was used both as a space-holder phase and as an oxidation shield. In the method, firstly, nickel and potassium bromide powders were mixed according to the desired void ratio. The obtained nickel-potassium bromide powders were pressed in a hydraulic press and turned into pellets (diameter: 13mm). Then, these pellets were pressed again in a wider mold (diameter: 21mm) so that all surfaces were covered with potassium bromide, and the encapsulation process was carried out. These capsules were embedded in potassium bromide in an alumina crucible for sintering. The sintering process was carried out in an open atmosphere at 1050 °C for 60 minutes. After the sintering process, the crucibles were kept in water to dissolve the crystallized potassium bromide around and inside the sample. Density, macrostructure, microstructure and EDS analyzes were performed on the samples. It was observed that open cell pores (58.3 - 78.1% vol) with diameters varying between 5 and 500 µm, which are homogeneously distributed in nickel, have been successfully obtained. In addition, it was proved that nickel foam materials can be produced in different sizes and designs.
Structural analysis of embedded hollow tubes on straight and curved platforms under thermal loads
Authors: YAVUZ Mustafa Murat
Published: December 2021

Tube systems are widely used in heat transfer and intensive research is being done on positioning tubes on a platform. The platform structure is constantly exposed to thermal changes under operating conditions and the resulting stresses cause damage to existing systems. In this study, 8 thin-walled tubes were positioned on flat and curved platforms that were widely used and the stress behavior under thermal effects was investigated. Finite element analysis was used, and steady-state thermal condition was considered in the numerical investigation. The effects of temperature difference between platform surfaces and the thermal conductivity at the tube surfaces were investigated. It has been determined that the stress on the platform is higher than the stress on the tubes and the increase in the temperature difference on the platform surfaces increases the stress drastically. The increased thermal conductivity coefficient on the tube surface reduced the stresses on the platform and increased fatigue performance. Flat platform has lower contact pressure and platform stresses and better fatigue behavior. Results are discussed in detail.

Published: December 2021

Based on data from the Directorate General of Plantations in 2018, the tendency of expanding the acreage of self-contained oil palm plantations is continuing. It is feared that the continued expansion of land by both companies and smallholder plantations could cause natural damage and gas emissions that lead to the loss of biodiversity. This has led to a lot of criticism from various parties stating that the palm oil industry is responsible for all the risks that occur. To overcome this, the government implements a governance system (certification) for the entire palm oil industry. Indonesian Sustainable Palm Oil (ISPO) is a certification system issued by Indonesian government to reduce the negative impacts of land expansion and to achieve sustainable palm oil. In its implementation in the field, the implementation of ISPO encounters several obstacles, particularly independent plantations such as difficult and complex legality issues, lack of knowledge that causes a lot of land clearing by burning and continuous land expansion. This research needs to be conducted to see the readiness of independent oil palm smallholders in implementing ISPO with descriptive methods and gap analysis. This research was conducted in Engkersik Village, Sekadau Hilir District, Sekadau Regency, the method of determining the sample was using slovin, amounting to 31 farmers. ISPO consist of 4 principles, criteria and indicators are used as variables in this study. The analysis results of all the principle show that farmers are ready with a readiness percentage of 60.9%, where each principle’s percentage of The Legality of Self-Manage Plantation is 75%, The Organization of Farmers and Management of Self-Manage Plantation is 62%, Environmental Management and Monitoring is 43%, and Continuious Business Improvement is 58%, although there are still gaps in its application. For this reason, it is necessary to carry out more effective socialization and training to farmers to minimize the gap.

Authors: Sailah Illah , Hambali Erliza , Aulyana Fadilla Eka
Published: December 2021

The development of bio degreaser made from palm oil surfactant aims to substitute bio degreaser made from petroleum surfactant which is less environmentally friendly. The development was carried out by formulating palm methyl ester sulfonate (MES) surfactant with oxalic acid as metal or non-metal cleaning agent. The purpose of this study was to obtain the best concentration of oxalic acid in the bio degreaser formulation. The concentrations of oxalic acid tested were 7, 8, and 9%. The best concentration of oxalic acid was determined based on the results of characteristic tests and detergency tests, namely 7% oxalic acid concentration. The resulting bio degreaser product has a pH of 1.6; viscosity 1.39 cp; specific gravity of 1.012; surface tension 32 dyne/cm and detergency power 84%. Furthermore, the resulting bio degreaser was added with Diethanolamioda (DEA) surfactant. The purpose of adding DEA surfactant is to increase the pH and lower the surface tension. The formulation results showed an increase in pH from 1.6 to 3.2 and a decrease in surface tension from 31.97 dyne/cm to 28.70 dyne/cm. In addition, there was an increase in viscosity from 1.39 cp to 1.62 cp and specific gravity from 1.012 to 1.018.
Third mission activities at the University of Miskolc
Authors: Horváth Zita
Published: December 2021

In addition to their teaching and research activities, higher education institutions play an important role in the social development of countries. Their indirect economic impact is unquestionable. The so-called “third mission” summarizes the activities and impacts of higher education institutions on their environment. Beyond the obvious range of training and research services this impact of the higher education institutions is particularly strong, but typically works through indirect and soft means and therefore it is difficult to quantify. The Hungarian network of institutions is potentially suitable for fulfilling its third mission role. Local training, research, economic and regional development connections are given even in the case of institutions with a narrower profile. Community spaces, service (sports, cultural, library, and public collection) infrastructures are available to the local intelligentsia, the institutions act as living knowledge bases, but they often serve as regional centers for cultural and sports activities as well. In my study, I write about the third mission activity of the University of Miskolc.
Bounds for the electrical resistance for homogeneous conducting body of rotation
Authors: Ecsedi István , Lengyel Ákos József , Baksa Attila , Gönczi Dávid
Published: December 2021

A mathematical model is developed for the steady-state electric current flow through in a homogeneous isotropic conductor whose shape is a body of rotation. The body of rotation considered is bounded by the coordinate surfaces of an orthogonal curvilinear coordinate system. The equations of the Maxwell’s theory of electric current flow in a homogeneous solid conductor body are used to formulate the corresponding electric boundary value problem. The studied steady-state conduction problem is axisymmetric. The determination of the steady motion of charges is based on the concept of the electrical conductance of the conductors the inverse of which is the electrical resistance. The exact (strict) value of the electrical resistance is known only for bodies with very simple shapes, therefore, the principles and the methods that can be used for creating lower and upper bounds to the numerical value of electrical resistance (electrical conductance) are important. The derivation of the upper and lower bound formulae for the electrical conductance of axisymmetric ring-like conductor is based on the two types of Cauchy–Schwarz inequality. The condition of equality of the derived lower and upper bounds is examined. Several examples illustrate the applications of the derived upper and lower bound formulae.
Dual-hop Relaying Networks for Short-Packet URLLCs: Performance analysis and Optimization

Published: December 2021

This paper investigates short-packet communications for the dual-hop decode-and-forward relaying system to facilitate ultra-reliable and low-latency communications. In this system, a selected relay having the highest signal-to-noise ratio (SNR) serves as a forwarder to support the unavailable direct link between the source and destination, whereas a maximum ratio combining technique is leveraged at the destination to achieve the highest diversity gain. Approximated expressions of end-to-end (e2e) block error rates (BLERs) are derived over quasi-static Rayleigh fading channels and the finite-blocklength regime. To gain more insights about the performance behavior in the high-SNR regime, we provide the asymptotic analysis with two approaches, from which the qualitative conclusion based on the diversity order is made. Furthermore, the power allocation and relay location optimization problems are also considered to minimize the asymptotic e2e BLER under the configuration constraints. Our analysis is verified through Monte-Carlo simulations, which yield the system parameters' impact on the system performance.

Pengaduan saat ini umumnya masih menggunakan tatap muka sehingga masyarakat harus datang ke instansi tersebut untuk melakukan pengaduan. sedangkan masyarakat banyak yang tidak tau tentang birokrasi pemerintahan desa hal ini menjadi masalah terjadinya kesalahan pengaduan masyarakat yang tidak sesuai jalur birokrasinya, sehingga pengaduan masyarakat kurang ditanggapi oleh pihak desa. Karena itu penulis tertarik untuk memberikan sebuah solusi dari persoalan tersebut maka dibuatlah aplikasi pengaduan masyarakat. Semoga dengan dibuatnya aplikasi pengaduan masyarakat dapat memudahkan masyarakat untuk melakukan pengaduan tanpa harus datang ke desa dan pengaduan dapat disampaikan sesuai jalur birokrasi desa. Pada sistem ini, aplikasi android hanya dapat diakses oleh user yaitu masyarakat , sedangkan untuk admin nya sendiri menggunakan web untuk mempermudah dalam pengolahan data pengaduan dari masyarakat dan pembuatan berita. adapun peneliti menggunakan metode SDLC (System Development Life Cycle) dalam melakukan perancangan aplikasi dengan model proses Waterfall. Dalam penelitian ini selain memaparkan kajian teori sebagai dasar penyusunan, peneliti juga akan membahas mengenai perancangan sistem dan pembuatan aplikasi mobile android sehingga diharapkan dapat membantu kinerja desa dalam menangani pengaduan dari masyarakat dengan lebih mudah dan cepat.

O presente artigo tem por objetivo o estudo realizado através da análise de dados com o auxílio do software Power BI em uma loja virtual de instrumentos musicais. Para a elaboração desse contexto foram exportados os dados através da plataforma “ADM” da loja virtual, onde foram coletadas as informações do cadastro dos clientes, históricos de pedidos, histórico de vendas, carrinhos abandonados e finalizados. Foi aplicada uma metodologia de “Frete Grátis” baseada em dois estudos de caso, o primeiro estudo relaciona “Abandono de Carrinho em um E-Commerce” e para a certificação da teoria, utilizou-se também a correlação com a pesquisa “A Influência do Frete no E-Commerce Brasileiro”. Ambas as pesquisas citam que para o cliente o frete é o ponto mais critico ao se finalizar ou não uma compra em lojas online, e que apontam como atrativo a modalidade “Frete Grátis”. Com os resultados obtidos após a aplicação do método por três meses, foram realizadas novas análises e comparativos a fim de confrontar a eficiência dos estudos de caso versus a prática. O resultado apontou que a modalidade aumentou a média trimestral de vendas em 57,8% contemplando 100 novas vendas a mais que o período anterior, e diminuiu em 34,2% o abandono de carrinhos que em quantitativo representam 64 carrinhos. Deste modo pode-se comprovar que o “Frete Grátis” é eficaz para alavancagem de vendas e queda no abandono de carrinhos.

The innovative infrastructure of the region symbolizes the totality of the objects of inno-vation activity and the correlation between them. The creation and development of in-frastructure is impossible without taking into account the peculiarities of each of the re-gions, its specialization, which also affects the innovation and investment potential of the region. As a result, the formation of inno-vative infrastructure provides a powerful in-centive for the development of the regional economy. The purpose of the study is to study the process of creating and developing the innovative infrastructure of the region on the basis of the already existing theoretical and methodological groundwork and practi-cal experience, as well as to determine the "driving" mechanisms of innovative devel-opment. The paper considers the main prob-lems of the formation of innovation infra-structure, assesses the current state of inno-vation infrastructure and formulates the "driving" mechanisms of innovative devel-opment. It is proved that the innovative infra-structure is the driver of the innovative de-velopment of the region, therefore, the pro-spects for the development of innovation stimulation and the expansion of network interaction are especially important.
