Authors: Fedoreyiko V
Published: October 2023

The article analyzes ways of transforming Ukraine's energy system based on the "Smart Grid" concept with the implementation of distributed generation projects. The expediency of using new tools for the decentralization of thermal and electrical energy sources as a component of small-scale energy, focused on renewable types of uncertified biofuel of local origin, is substantiated. The energy, economic, ecological and social significance of the introduction of systems of thermochemical destruction of bio-waste with the help of jet-vortex generators-utilizers in energy-intensive technologies has been proven. New approaches to the process of heat energy generation in energy-intensive processes of the agro-industrial complex are proposed using the example of grain drying. Thermal engineering means of thermochemical destruction of biowaste, heat exchange system and disposal of combustion products have been developed. A full cycle of production tests of automated jet-vortex generators-utilizers was carried out, taking into account non-deterministic technological parameters (temperature, humidity, productivity, physico-chemical properties of fuel). The cost of thermal energy in technological processes of grain drying is 5...7 times lower than traditional hydrocarbon. Given the presence of a functional heat exchanger, the drying process takes place with heated clean air, which has a positive effect on the quality indicators of the grain. Taking into account the challenges that exist in the electric power industry of Ukraine, a project of a cogeneration plant based on a generator-utilizer and an air turbine is proposed, which, with the help of a heat exchanger and a compressor, converts part of the thermal energy into mechanical energy. With the help of an electric machine converter, electricity is produced, which meets the needs of the heat engineering module of the installation. The total efficiency of the cogeneration plant is about 80 %.

Published: October 2023

The paper presents the results of a comparative analysis of the exergetic efficiency of heat recovery systems of boiler plants. The need to ensure the efficient operation of heat recovery systems for various purposes determines the importance and relevance of research conducted in this field. The purpose of the work is to increase the exergetic efficiency of heat recovery systems of various purposes. The results of solving the tasks necessary to achieve the set goal are given:

- submit heat utilization systems of various purposes in the form of structural diagrams with the identification of exergetic flows of heat carriers;

- choose exergetic efficiency evaluation criteria for heat recovery systems of various purposes, calculate their values and conduct a comparative analysis;

- develop recommendations for the use of heat recovery systems for various purposes, taking into account the specifics of their application.

For research, a complex methodology was used, which combines structural-variant methods of exergetic analysis with methods of presenting exergetic balances in matrix form. Three types of heat recovery systems with different numbers of consumers of recovered heat were considered. Structural diagrams of heat recovery systems of various purposes with identification of exergetic flows of heat carriers between individual discrete elements have been developed. Exergetic losses, thermal exergetic criterion and exergetic efficiency were selected as criteria for evaluating exergetic efficiency. Their values were obtained for heat recovery systems and their elements at different values of the relative power of the boiler. The largest exergy losses occur in the water-heating heat exchanger, smoke extractor and pumping system, the smallest - in the air-heating heat exchanger and gas heater. An increase in the relative power of the boiler leads to an increase in the relative contribution of the exergy losses of the water heating heat recovery system, as well as the pumping system and the pipeline system to the total exergy losses in the heat recovery system. It has been established that increasing the number of consumers of recovered heat in the heat recovery system and using rational ways of reducing total exergy losses increases the efficiency of heat recovery systems. Further developments in this field will allow to increase the exergetic efficiency of heat recovery systems for various purposes.
APPLICATION OF A LOCAL APPROACH FOR EVALUATING TRANSFER PROCESSES IN THERMAL POWER EQUIPMENT
Authors: Suprun T
Published: October 2023

It is known that, as a rule, heat carrier flows in the flow path of thermal power equipment are significantly turbulized due to many disturbing factors (increased turbulence, velocity unsteadiness, pressure gradients, local closed separations, etc.). The results of comprehensive studies of transfer processes under complex conditions of interaction between external (increased turbulence) and internal (separation) turbulence effects, typical for heat and power equipment, make it possible to develop measures to improve the thermal efficiency of working surfaces and the coolant supply system.

The object of this study is the heat exchange surfaces of power, chemical and electronic equipment, as well as coolant supply systems for the development of energy efficient heat technologies.

The purpose of the work is to develop methods for evaluating the transfer processes in thermal power equipment based on local control of thermophysical parameters in characteristic zones of the working environment.

Research method - physical modeling of turbulent effects of different nature and processes of heat, momentum and mass transfer using hot-wire, electrocalorimetric measurement methods and thermal mass analogy methods.

The studies were carried out in specially made experimental samples of installations that completely reproduce the operating conditions of a full-scale installation in terms of geometric parameters and coolant supply system.

The advantage of the work is the local approach, which allows fixing thermophysical parameters in a characteristic zone of the working space. The use of this approach makes it possible to control the most dangerous heat-stressed areas and takes into account the spatial non-uniformity of the temperature field, which is the basis for developing measures to improve the thermal efficiency of working surfaces.

The paper considers a generalized study of the local approach application on the examples of assessing the impact of increased turbulence, local closed separations, flow with periodic nonstationarity on the transfer processes in the flow part of heat and power equipment, as well as for developing an effective coolant supply system for the final drying of plant materials.

Published: October 2023

As the conducted studies show, deviations and asymmetry of the outside have the greatest impact on the electric drives of production machines and mechanisms.

Voltage asymmetry leads to losses that have an electromagnetic and technological component.

Studies on the effect of voltage asymmetry on the technological characteristics of working machines and mechanisms have shown that their productivity decreases with voltage asymmetry. However, there are no studies on the influence of spring asymmetry on the energy characteristics of working machines.

The purpose of the research is to determine the influence of voltage asymmetry on the energy characteristics of milk separators.

With voltage asymmetry, constant and variable losses in an asynchronous electric motor change.

It is proposed to carry out an energy assessment of the milk separator based on the specific power consumption.

The influence of voltage asymmetry on the energy characteristics of milk separators was studied. The dependence of the specific power consumption on the change in stiffness of the mechanical characteristics of the electric motor, which is caused by voltage asymmetry, is obtained. It was established that slippage and power losses increase with voltage asymmetry. As a result, specific power losses in milk separators increase.

Published: October 2023

An analysis of literary sources in which heat pump heating and air conditioning systems were studied over the past 10 years was carried out. It was determined that research for heat pumps using vertical soil heat exchangers was conducted more in the empirical plane. The authors analyzed the effectiveness of using existing systems that work for heating and air conditioning in different countries. The results of many studies are given, which show that, in fact, the use of ground heat pumps in a temperate climate only in the heating mode entails the exhaustion of the thermal potential and the impossibility of its use in the future. Theoretical studies at the system design stage are not sufficiently presented, and the issue of predictioning the efficiency of the use of such systems is not disclosed. In this regard, it is proposed to investigate the energy efficiency of the heat-pump air conditioning system based on vertical soil heat exchangers.

A heat pump air conditioning system based on a vertical soil heat exchanger is considered. Two research tasks were defined: analysis of efficiency in active and passive modes of conditioning. A thermodynamic analysis of the efficiency of the proposed scheme was carried out. The main operating parameters of the system at nodal points are defined. With the help of balance equations, the framework of the system's operation in passive and active modes according to the main parameters is determined. Graphical dependences of energy efficiency indicators on the determining parameters of the system were constructed and analyzed. It is shown at which parameter values the system has optimal operating costs. The results of the study are compared with those for the split system. The advantages and disadvantages of using the proposed solution are determined. It was determined that the heat pump system using soil heat for air conditioning with a vertical soil heat exchanger has stricter requirements for the thermal insulation of the air conditioning object than the system based on the air heat pump.

Authors: Bondarenko Yurii , Ivanyuk Igor
Published: October 2023

Non-afforested lands in Ukraine are the primary instrument for increasing the forest cover of the territory The issue of sand afforestation is relevant in the context of climate change. Treeless sand arenas are a source of dust storms, and deflationary processes that occur lead to negative consequences that are quite difficult to correct in the future. The purpose of this study was to summarise the experience and achievements of the branch “Myrhorod Forest Enterprise” of the State Specialised Commercial Enterprise “Forests of Ukraine” in afforestation of mobile sands in the conditions of the Forest-Steppe of Ukraine. Forest stands are established using one-year-old Scots pine seedlings on sandy soils to achieve the set goal. Testing is conducted using planting material grown under various conditions – in the open ground and in a greenhouse. Extended periods for establishing forest stands beyond agrotechnical terms are examined during the late spring and summer periods using rejuvenated planting material with partially damaged root systems. The current state of plantings within the Shyshatska sand arena is analysed. It is established that in general, the territory of the arena is represented by the entire range of types of forest conditions ranging from bors to mixed broad-leaved forests. The prevailing types of forest-growing conditions are given, among which dry and fresh forests are distinguished. Subors and su-deciduous forests are represented on small areas. Deciduous types of conditions are located mainly in the drained areas of the Psel River floodplain. The main forest-forming species on the territory of the arena is Scots pine, which occupies more than 60% of the territory. Also in the lowlands and floodplains of the Psel River stands of Black Alder and Common Oak grow. In the conditions of bors, Scots pine grows in III – Va bonitet class. In richer conditions, subor and su-deciduous forest cultures have better indicators and have a class I-II bonitet, but there are not many of them. The results of this study can be used in the afforestation of sandy lands in the Forest-Steppe of Ukraine and adjacent regions

Published: October 2023

Climate changes actualise the need for the transition of Ukraine’s agricultural business to agroforestry systems not only in the steppe but also in the northern regions of the country. The purpose of the study is to examine the features of creating protective stands of Walnut (Juglans regia L.) and Poplars (Populus × euramericana) in Polissya and in the Forest-Steppe of Ukraine. Experimental plantings of Walnut were created by one-year-old seedlings on sod-podzolic sandy loam soils of Zhytomyr Polissya and on carbonate soils of the Western Forest-Steppe, and the analysis of the survival rate of Poplar plantings was conducted on chernozems of the Right-Bank Forest-Steppe. It was established that on sod-podzolic soils, five-year-old plants of Walnut had an average height of 91.8 cm. At the age of 4, some of them bore fruit. The fruit-bearing trees had higher indicators of average height of 13.4% and a diameter of 71.5% compared to the rest. On carbonate soils, the trees showed substantially better growth in height, which is explained by the calciphile nature of the nut. It is determined that an effective way to increase the survival rate of one-year-old seedlings of Poplar varieties Dorskamp, Robusta and I-45/51 is to plant them without trunks. In all the examined varieties, during the first two years, the highest survival rate of seedlings was in the variant without a trunk – from 57.0 to 68.9%, while in seedlings with a trunk – from 50.3% to 68.1%. In 2022, due to irrigation, the survival rate ranged from 74.4% to 88.9%. The average height was mostly also higher in plants that grew from seedlings without a trunk. It was the largest in plants of the Dorskamp clone – 188.6 to 209.3 cm. In uncut plants of this variety, it ranged from 174.0 to 197.2 cm. The practical importance of the study lies in the possibility of developing new forms of Walnut and Poplar and improving technologies for creating forest lands with their involvement, which can be used in Polissya and Forest-Steppe conditions

Published: October 2023

Impact of pests and pathogens on trees, along with air pollution, are one of the most important factors that determine tree health in parks, squares, boulevards and streets of Kyiv. The purpose of the study was to monitor populations of dominant pests and foci of pathogens of tree ornamental plantings in Kyiv from 2020 to 2022. The objects of the study were horse chestnut leaf miner Cameraria ohridella Deschka & Dimic., leaf blotch miner moth Acrocercops brongniardella F., Linden gall mite Eriophyes tiliae Nal., and powdery mildew of Common Oak Erysiphe alphitoides Griffon & Maubl. U. Braun&S. Takam. Using the route method and the E.E. Geschele scale, population indicators were evaluated for Cameraria ohridella, Acrocercops brongniardella and Eriophyes tiliae. It is found that the number of these species is increasing. It is showed that these pests are common on tree species Aesculus hippocastanum L., Quercus robur L., and Tilia cordata Mill., in street and urban plantings under the intense influence of abiotic and anthropogenic factors. In 2021, compared to 2020, the prevalence of Cameraria ohridella increased by 7 times, the distribution of Acrocercops brongniardella ranged from 76-78%, and powdery mildew damage to Common Oak, on average, is 3.41. According to the results of the study, it is identified that the populations of Acrocercops brongniardella and Eriophyes tiliae are in a stable condition and do not have substantial deviations by year, while the invasive species Cameraria ohridella is characterised by a substantial increase in prevalence and abundance, which means that it causes an intense weakening and decrease in the decorative effect of Chestnut in the city’s street plantings. Annual intensive powdery mildew Erysiphe alphitoides damage was noted at young ordinary plantings of Common Oak along the main roads of the metropolis. The potential reproduction opportunities of phytophagous insect populations are analysed. In practice, the obtained results can be used for pest management and further monitoring of tree health in street and urban plantings in Kyiv

Authors: Сhurilov Andrii , Yakubenko Boris , Mezhennyi Volodymyr
Published: October 2023

Invasion of organisms pose a potential threat to the existence of natural habitats and lead to impoverishment of biological diversity. Particularly pronounced is the negative impact within the boundaries of the Middle Dnieper region, where approximately a quarter of vascular plant species are of alien origin. The purpose of the study was to identify the current species composition of alien vascular plant species, the specific features of their distribution outside the culture, naturalisation, and involvement in plant communities of Moshnohirsky Ridge biotopes. The species composition of plants was recorded by transects and releves in the habitats of representatives of alien plant species were conducted to achieve this goal. It was determined that the vegetation cover of forest and related biotopes in the research area is significantly contaminated with alien vascular plant species, amounting to 48 species from 45 genera and 29 families. Substantial involvement of alien species is noted in Forest biotopes of hornbeam-oak forests – 35.4%, and oak and pine-oak forests – 29.2%. Among the alien species that have a substantial impact on the structure of plant communities of these broad-leaved forest biotopes are Impatiens parviflora DC., Robinia pseudoacacia L., Acer negundo L. Over time, the majority of introduced species are considered neophytes (81.3%), with a significant portion originating from North America (43.8%), the Mediterranean region (16.7%), and East Asia (8.3%). In terms of their penetration into natural ecosystems, species that are capable of actively integrating into natural communities, namely agriophytes and agriocoenophytes, hold high positions (a total of 30.2%). In contrast to these groups, limited alien species without active distribution – ephemerophytes and colonophytes are substantially represented in the groupings of the research area (30.6%). The identified patterns of distribution and cenotic distribution of alien species are the primary basis for the formation of optimal measures to counteract new invasions in forest communities and restrain the process of population compaction for species that already have a wide distribution within the research area

Sahnya sebuah  perkawinan adalah sesuatu  hal yang sangat krusial yang  berkaitan erat dengan akibat-akibat perkawinan. Suatu perkawinan dikatakan  sah maka kedudukan hukum mengenai akibat perkawinan ini terutama  mengenai  keturunan (anak) dan harta akan menjadi tegas dan jelas. Harta yang diperoleh selama perkawinan berlangsung mempunyai hubungan hukum dengan kedua belah pihak yang telah melangsungkan perkawinan. Begitupun juga dengan keturunan yang lahir dalam ikatan sebuah perkawinan yang sah juga mempunyai hubungan hukum dengan orang tuanya.Kendatipun  sudah diatur  secara tegas dan jelas dinyatakan dalam Undang-undang Nomor 16 Tahun 2019 tentang Perkawinan, dalam Pasal 2 ayat (2)  menyatakan bahwa tiap-tiap perkawinan dicatat menurut peraturan perundang-undangan yang berlaku. Namun dalam kenyataannya masih banyak perkawinan yang dilakukan hanya sesuai ketentuan ajaran agama masing-masing dan belum dicatat pada pegawai yang berwenang/belum memiliki bukti Akta nikah. Penyebabnya bermacam-macam seperti pernikahan poligami yang belum mendapat izin dari isteri pertama, perceraian yang dilakukan diluar pengadilan dan juga kurangnya kesadaran untuk mencatatkan perkawinan karena mereka beranggapan menikah yang penting sah menurut hukum agama dan tidak perlu dicatatkan.

Past studies have delved into the genetic factors underlying anti-tuberculosis drug-induced liver injury (AT-DILI), primarily concentrating on polymorphisms in genes responsible for drug-metabolizing enzymes. However, the immune system's potential impact on drug adverse effects, specifically through genes such as HLA, has received limited attention. Previous research has notably revealed an association between HLA-DQB1*05 and AT-DILI, specifically the prevalence of the HLA-DQB*05:02 allele in AT-DILI patients. In light of this, our study aimed to investigate a potential link between HLA-DQB1*05:02 alleles and AT-DILI. In this study, we included 51 AT-DILI cases and 59 controls belonging to the Javanese ethnic group. The HLA-DQB1*05:02 genotypes were determined using a customized PCR-based typing method, and the results were further confirmed by analyzing five samples via the Luminex assay. Our findings revealed a significant association between HLA-DQA1*05: 02 and the risk of AT-DILI (P = 0.022; OR (95% CI) = 6.11 (1.25-29.74)). Moreover, the consistent results obtained from the Luminex assay validated the reliability of the custom PCR-based genotyping approach. This preliminary study sheds light on the relationship between the HLA-DQB1*05:02 allele and AT-DILI within the Indonesian population. Furthermore, our study demonstrates the dependability of custom PCR-based genotyping in detecting HLA-DQB1*05:02 alleles. Nevertheless, further research is imperative to corroborate and expand upon our findings.

Proteinuria is caused by kidney damage. Qualitative examination of urine protein can be carried out using the dip strip method, 6% acetic acid and 20% sulfosalicylic acid. The aim of this research is to determine the accuracy and precision of urine protein examination using the dip strip method, 6% acetic acid and 20% sulfosalicylic acid. The research was experimental with repeated measurements of levels carried out visually and gave positive results of 1, 2, 3 and 4. The research was carried out in January 2022 using a research sample of 20 proteinuria positive patients at RSJD Dr. Amino Gondohutomo. The results of this research are that all methods meet the 12S rules where there is 1 control that is more than ± 2SD (still in the ± 3SD area), categorized as a warning/warning of method malfunction (needs more careful analysis). The best method is dip strip because it has the lowest Coefficient of Variation (KV) value, namely 0.497%. The method can still be used for patient care. The coefficient of variation obtained was dye liquid 0.497%, 6% acetic acid 0.654%, and 20% sulfosalicylic acid 0.630%. The smaller the KV value (%) the more thorough the system/method. The conclusion that can be drawn from this research is that the dip strip is a method that has the best accuracy and precision compared to the 6% acetic acid and 20% sulfosalicylic acid methods because it has the smallest coefficient of variation (KV%) value, namely 0.497% and meets the 12S rules. Researchers recommend always ensuring that the research location has the required samples with adequate volume, urine protein examination can be carried out using the dip strip method, researchers can then carry out urine protein examination regarding the sensitivity and specificity of the three qualitative methods

Background: Attention is an essential cognitive ability that is necessary in other cognitive processes. Only few studies have focused on decline in specific functions of attention in older adults with cognitive decline. No research explores the difference in the proactive and reactive mode of control between the healthy control (HC) and older adults with subjective cognitive decline (SCD). Objective: The current work investigated whether there was any decline in alerting, orienting, and executive control in SCD. Particularly, the present study further explored the impairment of the proactive and reactive control in SCD. Methods: We recruited 25 HC and 26 SCD. All participants first finished a set of neuropsychological assessments. They then completed an Attention Network Test for measuring the alerting, orienting, and executive control, the List-wide and the Item-specific Proportion Congruency Effect task for measuring the proactive and reactive mode of control, respectively. Results: No difference was found in alerting, orienting, and executive control measured by the ANT between SCD and HC. The results also indicated no difference in the reactive control between SCD and HC. However, older adults with SCD performed worse in the proactive control as compared to HC. Conclusion: Older adults with SCD showed an impairment in the proactive control. The current findings help us better understand objective decline in cognitive domains other than memory and shed light on early assessment and prevention of AD.

A literature review was conducted to develop an experimental stand for testing pumps. It was established that frequency regulation is one of the quantitative energy-saving methods of controlling the operation of the pumping unit. At the same time, the influence on the pump unit is carried out by changing the operating point by means of variable pump curve. The hydraulic schemes for experimental study of frequency-controlled pumps presented in the article have certain disadvantages: 1) the location of the pump relative to the tank is ambiguous regarding the operation of the pump under flooded suсtion; 2) pressure regulation is provided only in the direction of its decrease; 3) refers rather to the automation of pumping installations. On the designed and manufactured experimental stand, it is possible to study the operation of the pump with the use of a frequency converter and without it, through a bypass line. When testing the pump for systems that operate according to the fluid level in the suction tank, use either a valve on the discharge pipeline (with the use of a frequency converter) or a ball valve on the discharge pipeline from the discharge tank (without the use of a frequency converter). In addition, pump testing using a frequency converter can be performed for pressure-operated systems. The installed frequency converter is a regulator of the flow of the working fluid, which allows adjusting of the pump discherge. The pump designed on the experimental stand is a self-suction jet that does not need to be installed under flooded suсtion. The discharge tank is located higher than the suction tank, which ensures the circulation of the working fluid by gravity. The working fluid will be water. The preliminary results, performed on the experimental stand, confirm the possibility of frequency regulation of the pump using a frequency converter.

This research aims to analyze how Puan Maharani's personal branding on the Instagram account @Puanmaharaniri approaches the 2024 presidential election. This research uses a qualitative approach using the qualitative content analysis method based on the constructivist paradigm. Data collection was carried out using observation and documentation techniques and using three stages in analyzing the data, namely: data collection/reduction, presentation, and verification/conclusion. The research results show that the strategy for creating Puan Maharani's personal branding on the @puanmaharaniri Instagram account ahead of the 2024 presidential election was built by creating interesting content through the Instagram account with the tools used in personal branding on the @puanmaharani Instagram account, namely first, text; second, short videos; and third, photos. The concept of creating personal branding built by Puan Maharani through her Instagram account includes eight personal branding concepts by Peter Montoya. Some of Puan Maharani's branding that dominates in the formation of personal branding on her Instagram account are concern for small communities (little people), gender equality, and leadership. The overall branding built by Puan has not been able to increase her electability due to inconsistency in one strong branding attached to Puan Maharani, so that she becomes a figure known for this branding.
