Theoretical aspects of innovative development of unified heat supply organizations in the conditions of transition to a new energy system

Introduction. Heat supply, which is one of the most important areas of housing and communal services in our country, is in critical condition, as evidenced by the increase in the number of accidents on heating networks and an increase in heat loss over the past 25 years. The current situation necessitates the modernization of the sphere under consideration, which should be associated with the introduction of modern technologies and innovations in the activities of heat supply. In addition, a number of researchers note that currently there is a change in the energy system based on the partial replacement of existing energy sources towards energy-efficient devices, which, on the one hand, allow meeting growing energy needs, and, on the other hand, reduce the negative impact on the environment. Therefore, it is proposed to consider the modernization and innovative development of heat supply, including in the context of compliance with environmental safety properties. It is determined that the subject of heat supply, which should take responsibility for the implementation of the vector of its innovative development in a certain territory, should be unified heat supply organizations, fixed by legislation as a single center of responsibility, modernization and technological development of heat supply. In this regard, the purpose of the study is to consider the theoretical aspects of the innovative development of unified heat supply organizations in the conditions of transition to a new energy system.
 Materials and methods. The theoretical and methodological basis of the study was the works of Russian and foreign authors on the issues of innovative development of economic systems, as well as the work of researchers proving the relationship of cyclical economic growth with innovative development. The study used methods of analysis and synthesis, as well as the method of comparative estimates.
 Results. The study of approaches to the innovative development of economic systems allowed us to conclude that, despite the crisis phenomena that are natural in their cyclicity, the decline in the development of these systems is overcome with greater speed in cases of innovation in the system, which, according to the author, should be reflected in practice in the mo­dernization of heat supply, in particular, through the innovative development of unified heat supply organizations.
 Conclusions. In the conditions of changing energy structure, the innovative development of unified heat supply organizations should be considered not only from the standpoint of increasing the efficiency of heat supply in Russia, but also from the standpoint of increasing its energy efficiency and minimizing the negative impact on the environment.

THE EMERGENCE OF TECHNOPARKS AS A NEW ORGANIZATIONAL FORM: A STUDY FROM THE PERSPECTIVE OF COEVOLUTION

This study aims to reveal the emergence of technoparks as a new organizational form, the conditions, and actors effective in this process from the perspective of coevolution. Following the exploratory nature of the research, we preferred a qualitative method and collected the data through document analysis and semi-structured interviews. The findings showed that the technopark form emerged in a coevolutionary process. Moreover, the transition to a free-market economy on January 24 in 1980 is the event that initiated the coevolution process. Then, conditions such as ensuring university-industry collaboration triggered the interaction between the actors in the emergence process of technoparks. Also, we revealed that Technology Development Center was the catalyst that accelerated the process, and METU Technopark, which was established before the law, was a proto form. Furthermore, the government shaped the functioning of the form with the law it enacted. Our study contributes to the literature explaining that in an institutional environment how environmental changes and conditions trigger interactions between actors and how the outcomes of the actors' interaction reveal technoparks as a new organizational form.

Reevaluation of Spectral Parameters and Neutron Fluxes in IC-7 Irradiation Channel of TRIGA MARK I IPR-R1 Research Nuclear Reactor

Abstract The core configuration of the Training Research Isotopes General Atomics (TRIGA) MARK I IPR-R1 nuclear research reactor at Nuclear Technology Development Centre (CDTN), Belo Horizonte, Brazil, has been modified six times since the first criticality and the neutron fluxes have been determined using experimental and semitheoretical methodologies determining the neutron fluxes in different irradiation channels and devices, applying different procedures and materials. This reactor operates at 100 kW; however, after new configuration for 250 kW in 2001, the carousel no longer rotates during irradiations aiming at preserving the rotation mechanism. In 2003, the spectral parameters were determined experimentally by the “Cd-ratio for multimonitor” in five specific channels aiming at the application of neutron activation analysis (NAA) k0-standardized method. The determinations were repeated applying the same procedure in 2016, 2018, and 2019. Values for thermal and epithermal neutron fluxes as well as f and α spectral parameters were determined. The experimental results for certified reference material BCR-320R were calculated by the k0-method of NAA, using the spectral parameters for irradiation channel IC-7 obtained in 2003, 2016, 2018, and 2019 and evaluated by En-score. The values showed that the differences in the results compared to those in 2003 were lower than 2.5%, inside the uncertainty of the method. It shows that the k0-method installed in CDTN is reliable and useful for various purposes. The results of the spectral parameter f presented small differences, in a period of 16 years, pointing out the stability of operation of the reactor TRIGA MARK I IPR-R1.

Do leaders have an influence on strengthening entrepreneurial orientation? Empirical evidence from SMEs of Turkish techno-parks

PurposeIn this study, the authors aim to test the reflections of two so-called universal leadership styles -paternalistic leadership (PL) and transformational leadership (TL)- on entrepreneurial orientation (EO) and ultimately on firm performance (FP) within the context of SMEs of a developing country, Turkey. Moreover, examining the contingency of uncertainty avoidance (UA) on the relationship between EO and firm performance is another aim of the study.Design/methodology/approachIn this explanatory cross-sectional study, by studying a dataset of 345 small and medium-sized (SME) Techno-park companies in Turkey based on using the Partial Least Squares (PLS) method, the authors try to examine the antecedent role of PL and TL on EO and ultimately on FP. Moreover, we followed a mediation procedure to reveal the mediator role of EO on the relationship between leadership style and firm performance. Finally, the authors also conducted a moderation analysis through SmartPLS 3.0 to explore the contingency of UA on the relationship between EO and firm performance.FindingsStudy results indicate that TL is a significant antecedent of EO that results in higher firm performance. However, while PL has a negative impact on entrepreneurial orientation, the results provide no statistical evidence in support of a significant relationship between PL and firm performance. Moreover, the findings indicate that the higher UA, the weaker the relationship between EO and firm performance.Practical implicationsManagers, following a TL approach, can successfully encourage their subordinates to be innovative and creative. Transformational leaders are conducive to both entrepreneurship and firm performance within the context of technology-based startups. Besides, avoiding the risks and uncertainties naturally weakens the consequences of EO. Hence, EO, as an essential intangible resource, requires a proper cultural context to result in a competitive advantage.Originality/valueThis research provides a comprehensive understanding regarding the interrelationships amongst transformational and paternalist leadership styles, EO and firm performance within an UA context in Small Business and Technology Development Centers (SBTDCs) and Techno-parks. To the best of the authors' knowledge, no other researcher has studied those links in a holistic manner in general, particularly on the SMEs of Techno-park firms of a developing Eastern country. The findings significantly enrich the literature on paternalist leadership and entrepreneurship orientation in a cultural context.

The genetic improvement program of the Seed Technology Training and Development Center works on the agronomic characterization and the content of bioactive compounds in eight genotypes of habanero pepper. The objective is to select genotypes with good agronomic performance that allow the generation of inbred lines to obtain hybrids. In this study, the agronomic performance and the content of bioactive compounds (capsaicinoids, polyphenols, and antioxidant capacity) were evaluated in eight genotypes of habanero pepper grown in the southeast of Coahuila, Mexico, identified as HNC-1, HNC-2, HNC-3, HNC-4, HNC-5, HNC-6, HNC-7, and HCC-8. The plants were grown in a greenhouse for 127 days, under a completely randomized design with four replications each. The results revealed that the yield (g·plant−1) and number of fruits per plant did not show significant differences between genotypes. However, for the fruit length, the genotypes HCC-8, HNC-7, HNC-6, and HNC-5 stood out with over 40 mm, while in equatorial diameter of the fruit, HCC-8, HNC-4, and HNC-2 stood out with 26.45, 26.46, and 25.12 mm, respectively. The results of the chemical analyses allowed us to identify that HNC-5 and HNC-6 had the highest capsaicin concentration (931.38 and 959.77 mg·kg−1), dihydrocapsaicin (434.95 and 445.89 mg·kg−1), Scoville Heat Units greater than 210,000, total phenols (67.54 and 71.15 mg/100 g) and total flavonoids (34.21 and 38.29 mg/100 g), respectively. The HNC-1 and HNC-6 genotypes had the highest carotenoids concentration with 103.96 and 105.07 mg/100 g, and HCC-8 registered the highest anthocyanin content with 22.08 mg C3GE/100 g. The antioxidant capacities showed significant differences (p ≤ 0.05) between genotypes, with a range of 43.22 to 110.39 µmol TE/100 g, 72.37 to 186.56 µmol TE/100 g, and 191.41 to 244.98 µmol TE/100 g for the tests of DPPH (2,2-diphenyl-1-picrylhydrazyl), ABTS (2,2′azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)), and FRAP (ferric reducing antioxidant power). The results of this research will be used to select habanero pepper genotypes that can be used in genetic improvement programs to increase the productive potential and the content of bioactive compounds in the fruits to expand their applications in the food industry.

In order to study the safety aspects connected with the permanent increase of the maximum steady state power of the IPR-R1 Triga Reactor of the Nuclear Technology Development Center (CDTN), experimental measurements were done with the reactor operating at power levels of 265 kW and 105 kW, with the pool forced cooling system turned off. A number of parameters were measured in real-time such as fuel and water temperatures, radiation levels, reactivity, and influence of cooling system. Information on all aspects of reactor operation was displayed on the Data Acquisition System (DAS) shown the IPR-R1 online performance. The DAS was developed to monitor and record all operational parameters. Information displayed on the monitor was recorded on hard disk in a historical database. This paper summarizes the behavior of some operational parameters, and in particular, the evolution of the temperature in the fuel element centerline positioned in the core hottest location. The natural circulation test was performed to confirm the cooling capability of the natural convection in the IPR-R1 reactor. It was confirmed that the IPR-R1 has capability of long-term core cooling by natural circulation operating at 265 kW. The measured maximum fuel temperature of about 300 oC was lower than the operating limit of 550 oC. It has been proven that without cooling in the primary the gamma dose rate above reactor pool at high power levels was rather high.

Development of mechanical engineering for extractive industries as a factor of economic development of macroregion siberia

One can consider the development of Siberia and the Far East also called macroregion Siberia as Russia’s comeback to its historic movement towards the East which will give Russia sustained economic growth based on the country’s entry into the global division of labor and its active position in the markets of the Asia Pacific Region. It is the region that has become the center of global economic and technological development in the 21st century. Gaps in the country’s economy should be overcome both between separate sectors of the economy and between regions. The development of Siberia and the Far East has huge potential for the development of Russia as a whole, and it will largely determine its geoeconomic prospects in the 21st century. Such development means the introduction of new approaches to the raw materials sector, the creation of transport and energy infrastructure, as well as the development of deep processing industries, the creation of a dynamic innovation sector, improving the living standards of the population and, in general, the formation of new environment for living and people’s self-actualization. Otherwise, Siberia and the Far East are doomed to be subsidized territories with low returns for the country and its inhabitants. According to the author, the development of mechanical engineering focused on the extractive industry can be one of the main factors ensuring the successful development of the economy of the macroregion Siberia and Russia.
