(2020) Tarasenko, Roman; Usenko, Stanislav; Shapovalov, Yevhenii; Shapovalov, Viktor
Ontology widely used to support various types of information management including information retrieval, storage, and sharing on the web. To construct ontologies special software are using, which allows users to build hierarchies and create semantic links. A range of open-source and commercial tools are available. They assist in the development of various ontologies, and called Ontology Editors.

(2019) Shapovalov, Viktor; Shapovalov, Yevhenii; Bilyk, Zhanna; Tarasenko, Roman; Atamas, Artem; Tron, Vitaliy.V.
The modern development of science and technology has provided high quantity of information. This information must be systemized and classified. For taxonomization of educational materials, it was proposed to use existing graph- generators and graph-visualizers of the TODOS IT platform. A separate aspect of the TODOS IT platform is the possibility of using a centralized web-oriented learning environment. Creation of the system and transdisciplinary knowledge is a problem of modern education, which can be solved by creating a centralized web-oriented educational environment. Using this approach is an important part of the learning process. Such a centralized web-oriented environment based on the ontological approach involves filling, adaptive educational services with information resources that reflect the conceptual system of a particular discipline. One of the systems providing not only collection of information but include its systemizing is centralized web-oriented educational environment based on Ontology4 system. Ontology 4 use elements of the TODOS. The paper presents specific developments of one centralized web-oriented educational environment can be used to teach different subjects such as biology, chemistry, Ukrainian language and literature, using the STEM approach.
Comparison of biogas production from chicken manure in the mesophilic and thermophilic modes
(2015) Salyuk, Anatoly; Zhadan, Sergiy; Shapovalov, Yevhenii
During the experiment concentration of methane in the biogas increased faster with increase of substrate moisture both under mesophilic and thermophilic conditions. However the increase in thermophilic mode was more dynamic. Mesophilic conditions are more suitable for methane fermentation of chicken manure at low moisture level. Substrate moisture value which could cease methane production both temperatures modes was not found.

The implementation of automated information systems can improve the efficiency of technological processes. In today's world, information technology plays an increasingly important role. One of the fields where information technology can increase economic profit is the industry. This is due to the fact that markets are dynamic systems where prices are constantly changing. Therefore, the availability of up-to-date information technology that will take into account the dynamics is important for production. That is why the development and improvement of decision-making systems have become increasingly relevant in recent times
Disposial of chiken manure by methane fermentation
(2013) Salyuk, Anatoly; Zhadan, Sergiy; Shapovalov, Yevhenii
Chickens badly absorb energy of plant feed. Most of it goes in the manure, Therefore, it can be used as a source of renewable energy in the production of biogas, which is one of the ways of its utilization. Chicken manure contains uric acid and undigested proteins, which are two main forms of nitrogen. The ratio C/ N is less than optimal. Anaerobic decomposition of these substances in chicken manure resulted in the production of high amounts of ammonia, which under certain concentration leads to inhibition of the process.However, it has been repeatedly shown that methanogens can adapt to increased concentrations of ammonianitrogen.Number of researchers have reported the successful operation of digestion systems for poultry manure. Mostof these systems were designed to operate in the mesophilic range.Given the wide margin of variation of parameters by different researchers of the process, the aim of our studywas to establish the optimal parameters of anaerobic digestion of chicken manure.Methane fermentation of chicken manure was carried out in the mesophilic temperature regime at thetemperature of about 35 °C. The fermentation was carried out in periodic regime. The investigation was carriedout at four different manure moisture levels (80 %, 85 %, 90 %, 95 %) and three different doses of inoculum(5 %, 10 %, 15 % of the volume).It has been found out that with the increase of manure moisture the biogas yield from one unit of drysubstance and correspondingly dry organic substances also increases, but from one unit of digester volume —decreases. The optimal parameters for carrying out anaerobic digestion of chicken manure are: moisture ofsubstrate at the level of 85 %, amount of inoculum — 5 %, duration of the process — from 13 to 20 days.

(2015) Zhadan, Sergiy; Shapovalov, Yevhenii; Patrick, Ngogang; Salyuk, Anatoly; Yakymenko, Igor
Poultry is one of the most intensive and mechanized agricultural sectors. Poultrymanure is the main ecological problem of poultry farms and its poor management can cause seriousenvironmental damage. As far as birds absorb energy of plant feed badly and that more than half ofthe energy is used unproductively – it goes to the manure, it can be seen as a powerful source ofrenewable energy. Methane digestion is an effective method of animal waste processing. Poultry manure has a higher fraction of biodegradable organic matter than other livestock wastes. The aim of our study was to investigate methanogenesis of chicken manure in a wide range of moisture content values in the mesophilic mode.
Method of alkaline destruction as the way to stop methanogenic effluent's gasification
(2019) Tarasenko, Roman; Starzhinska, Lydmila; Polunkin, Ievgen; Shapovalov, Yevhenii
One of the main problems which limit the distribution of biogas plants is the fertilizer gasification [1]. This process provides a problem of the fertilizer storage. Previously additional fermentation was conducted to solve this problem. It is characterized by additional biogas output, but it suppose to build additional biogas reactor and this it still does not supply completed fermentation [2]. We propose the process of alkaline destructions to solve this problem. It can provide production synthesis gas and humate.

(2018) Shapovalov, Yevhenii; Shapovalov, Viktor; Stryzhak, O.; Salyuk, Anatoly
Over the past decades, amount of scientific information has been growing exponentially. It became more complicated to process and systemize this amount of data. The approach to systematization of scientific information on the production of biogas based on the ontological IT platform “T.O.D.O.S.” has been developed. It has been proposed to select semantic characteristics of each work for their further introduction into the IT platform “T.O.D.O.S.”. An ontological graph with a ranking function for previous scientific research and for a system of selection of microorganisms has been worked out. These systems provide high performance of information management of scientific information. Протягом останніх десятиліть кількість наукової інформації зростала експоненціально. Обробити та систематизувати цю кількість даних стало складніше. Розроблено підхід до систематизації наукової інформації щодо виробництва біогазу на основі онтологічної ІТ-платформи «T.O.D.O.S.». Запропоновано вибрати семантичні характеристики кожної роботи для подальшого їх впровадження в ІТ-платформу «T.O.D.O.S.». Розроблено онтологічний графік з функцією ранжування для попередніх наукових досліджень та для системи відбору мікроорганізмів. Ці системи забезпечують високу ефективність інформаційного управління науковою інформацією.

(2018) Shapovalov, Viktor; Atamas, Artem; Bilyk, Zhanna; Shapovalov, Yevhenii; Uchitel, Aleksandr
It is demonstrated that one of the conditions for successful scientific and pedagogical work is exchanging of methodical materials, including with using of augmented reality. We propose to classify approaches of placing methodical materials on closed, open and open-moderated types. One of the important benefits of a closed type is the high quality of the methodical material, but it’s limited by amount of material and the lack of exchange opportunities that are problems, and there are no open-moderated resources in the Ukrainian language. The aim of this article is to analyze approaches of systematization of methodical material with using of augmented reality and recommend using of STEMUA for systematization of them. It is shown that STEMUA allows teachers to develop methodical material and place it on this platform. The platform automatically organizes methodical material in the database. Consequently, the platform is satisfying the methodical needs of Ukrainian teachers for material with using of complementary reality in the teaching. It is recommended for teachers and methodists to provide development and methodical materials with using of augmented reality and add them to the platform database.

(2019) Shapovalov, Yevhenii; Salyuk, Anatoly; Kotynskyy, Andriy; Tarasenko, Roman
The studies were conducted in batch mode in thirteen repetitions at humidity of 78, 80, 82 and 84%. The coefficient of variation of methane production varied from 14.84% to 35.17% in a mesophilic mode and from 14.4% to 78.21% in a thermophilic mode, which means high instability of the process. The moisture content had a much greater effect on the stability of the process in thermophilic conditions than in mesophilic ones.
Thermophilic methane fermentation of chicken manure in a wide range of substrate moisture contents
(2015) Salyuk, Anatoly; Zhadan, Sergiy; Shapovalov, Yevhenii
One of the effective ways of environmental management in poultry waste that allows the increase of energysaving and reduction of negative environmental impact is methane fermentation. Methane fermentation process is possible in three temperature modes: psychrophilic, mesophilic and thermophilic. Methane fermentation of chicken manure in thermophilic mode is less studied in comparison with mesophilic mode. The article presents the results of the study of methane fermentation of these wastes. The process was carried out in thermophilic conditions at 50 °C. Substrate moisture values varied from 72% to 99%. Biogas production ranged from 10,6 ml / g VS to 382,3 ml / g VS, methane production – from 1,8 ml / g VS to 207,9 ml / g VS. The maximum yield of biogas and methane per unit of mass was reached with the substrate moisture content of 92%. Production of methane from chicken manure in the thermophilic mode with low moisture level of the substrate was also possible despite the high content of ammonia nitrogen and free ammonia. However, with a decrease of the substrate moisture content lower than 80% efficiency of methane fermentation was at the same level and very low/
