The article analyzes Polish experience in the implementation of structural economic policy at the both national and regional levels. In particular, the key directions of implementation of structural reforms for the period 2013-2018 were analyzed, a comparison of Poland and EU-28 indicators on the expenditures for the implementation of innovations and employment level was carried out. The main problems of R&D activities in Poland, as well as effective instruments of innovation policy that contributed to the growth of innovativeness of the Polish economy, are determined. The factors of employment growth in the Polish labor market, problems and structural reforms in this direction are allocated. It is determined that urban development is an important part of Poland’s development policy in the medium and long term, but Polish cities, compared to most European cities, are not competitive enough and are limitedly included in both the European transport network and the intercity functional connections. It is found that the policy of development of Polish cities is grounded on the approach based on the synergy of sectoral policy and multilevel cooperation to strengthen the sustainable development of cities of any size, because the solution of many global problems of sustainable development (pollution, consequences of climate change, ensuring inclusive growth, etc.) is entrusted precisely to cities.

The volume of capital investment in the economy of region is an indicator that signals the level of socio-economic development; standard of living of the population; direction of innovation renewal in any sphere of economic activity; the ability to implement investment programs and projects, and as result, the increasing competitiveness and investment attractiveness both in both the domestic and international markets. Precisely that is why every city or community, region or country should pay considerable attention to the processes of revitalizing investment and creating favorable conditions together with market infrastructure to attract and stimulate investor activities. To assess the current status and tendencies in the development of capital investment in the Lviv region, the authors determine the position of the region in the rating among other regions of Ukraine in terms of the main indicators of capital investments, which are in the public domain and published on the official websites of the State Statistics Service of Ukraine and the Main Department of Statistics in Lviv region as of 2019. In particular, a comparative characterization of Lviv region and Ukraine is provided in terms of volumes, the share of the region to the total volume in the country and region, as well as the position in the rating among the regions according to the following indicators: capital investments by types of assets; capital investments by sources of financing; capital investments by type of economic activity; capital investments per capita. In addition, the dynamics of volumes and growth rates of capital investments of Ukraine and Lviv region for the period 2010-2019 is analyzed. The authors found that the dynamics of growth of capital investments in the Lviv region almost duplicates the dynamics in Ukraine. The research showed that in many respects Lviv region occupies high rating positions among the regions of Ukraine, which justified the high investment potential of the region and the ability to attract significant financial resources for the implementation of investment programs and projects. As result of the study, the authors proposed directions of revitalization of capital investment and improvement of the investment climate of Lviv region.

The article is aimed at analyzing modern approaches to management of IT projects and revealing the possibilities for their improvement based on the use of fuzzy logic in the overall decision-making circuit. Based on the analysis of the main rating sites, a conclusion has been made about the powerful development of IT outsourcing in Ukraine. The main international and domestic ratings regarding the Ukrainian IT outsourcing market are analyzed, criteria of success and reasons for rapid development are allocated. Upon analyzing a sufficient number of works and materials, the authors generalized, synthesized and classified the main difficulties that arise in the process of developing a portfolio of IT projects in terms of outsourcing companies. The most common instruments used to overcome these difficulties are analyzed. Focus is set on the Stage-Gate framework as the most appropriate for both adaptation and use in the process of managing the portfolio of outsourcing IT projects. A modification of Stage-Gate framework is proposed, which takes into account peculiarities of managing outsourcing IT projects and uses a fuzzy logic apparatus for decision-making when navigating between stages of the framework. The purpose of the modification is the possibility to create on its basis an expert system to support decision-making in the process of managing the portfolio of projects. This, in turn, leads to an overall increase in the level of project portfolio management. Prospects for further research are the introduction of the expert system into the practice of work of domestic IT outsourcing firms. The parallel direction consists in analyzing the international IT outsourcing market. This will help to increase the efficiency of the proposed modification and provide favorable conditions for the integration of the Ukrainian IT outsourcing market into the international practices.

The article is aimed at exploring the students’ views of the process of digitalization of the educational process, comprehending the consequences of digitalization, defining its capabilities in modern conditions, as well as proving the need for its use for the development of the individual and the acquisition of professional competencies. In domestic higher institutions of all forms of education, digitalization is rather forced than weighted and voluntary in nature. Compared to european colleagues, digitalization in Ukraine is but a forced, temporary step in counteracting the spread of the COVID-19 pandemic. But, given the unforeseenness of the pandemic, it may be necessary to digitalize the educational process over a long period. Therefore, in our opinion, it is necessary to identify directions for improving online learning in higher education institutions. Students are faced with the peculiarities of organizing the educational process online, in particular: the need to independently allocate time; digital format of communication with classmates; individual performance of not only independent work, but also tasks at seminar classes; lack of sufficient digital competencies among teachers, etc. At the same time, the online training regime generates in the students the development of high self-discipline for the rational distribution of educational time for the study of lecture material and the preparation of individual and other types of work; self-control over the timely performance of basic gymnastic exercises in the periods between double classes; as well as self-development and self-education, that is, the possibility of online visits to additional webinars / trainings / lectures, etc. That is, at the second stage of digitalization of the educational process, after adapting to its features, it is easier to feel the potential of positive opportunities for participants. However, it is impossible to complete the search for directions of the online learning optimization, which, for example, are associated with psycho-emotional, physiological negative changes in health, ensuring high quality of the educational process, uniform educational load during working periods, etc.

ABSTRACT The green revolution in the field of palm oil farming not only contributes to processed products but also produces large-capacity waste originating from its processing starting from the sterilization process, water from the clarification process, hydro cyclone (clay bath) water, and factory washing water. Palm oil mill effluent (LCPKS) contains dissolved and suspended solids in the form of colloids and oil residues with high BOD and COD. If this liquid waste is discharged directly into the water, it can pollute the environment. Some will settle, decompose slowly, consume dissolved dcxdcoxygen, cause turbidity, emit a sharp odor and can damage the aquatic ecosystem. To improve the parameters in the LCPKS so that it is feasible to flow to water bodies or the environment, an LCPKS treatment experiment test is performed by applying corona discharge with variations in voltage and length of time, then comparing the effect on parameters such as BOD, COD, pH and TDS on LCPKS before treatment and after treatment. From the treatment process using a corona discharge application with variations in voltage and time able to reduce BOD levels up to 35%, COD 36%, increase in TDS reached 71.56% and decreased pH by 4.11%.Key words: Palm oil mill effluent (LCPKS), Corona discharge application (Corona Discharge Treatment), COD, BOD, TDS, pH

Published: April 2021

ABSTRAKGas HHO atau brown gas merupakan suatu materi yang dapat menghemat penggunaan BBM dan menurunkan emisi gas buang bila ditambahkan pada pembakaran BBM. Untuk meningkatkan produksi gas HHO ini, maka perlu ditingkatkan kinerja dari sel electrolyzer yaitu suatu alat yang dapat memisahkan air menjadi hidrogen dan oksigen dengan menggunakan sumber listrik arus searah melalui proses atau pengurai cairan. Salah satu cara untuk meningkatkan kinerja sel electrolyzer adalah dengan melihat pengaruh dari tegangan listrik terhadap karakteristik kerja sel electrolyzer dengan variasi bahan elektroda. Dari hasil pengujian 10 variasi pasangan elektroda, terlihat bahwa bahan elektroda yang menghasilkan laju produksi gas HHO paling cepat dalam waktu 300,67 s yang menghasilkan 200 mL dicapai oleh pasangan elektroda yang menggunakan anoda aluminium (Al) dengan katoda aluminium (Al) atau tembaga (Cu). Pada pengujian ini dipilih elektroda berbahan aluminium dan tegangan pada pengujian yang ditentukan dengan tujuan untuk melihat karakteristik sel electrolyzer. Hasil pengujian menunjukkan semakin besar nilai tegangan yang diberikan maka nilai arus pada sel electrolyzer semakin meningkat, hal ini juga akan mengakibatkan suhu yang semakin meningkat serta waktu produksi gas yang dicapai sebanyak 200 cm3 semakin singkat.Kata kunci: Elektroda, Gas HHO, Sel electrolyzer

Social facilitation for conservation planning: understanding fairy tern behavior and site selection in response to conspecific audio-visual cues
Authors: Greenwell CN , Born KS , Admiraal R , Hodgson A , Dunlop JN , Loneragan NR
Published: April 2021

Simulated social facilitation techniques (e.g. decoys and call playbacks) are commonly used to attract seabirds to restored and artificially created nesting habitats. However, a lack of social stimuli and conspecific cueing at these habitats may limit the use of these sites, at least in the short term. Therefore, testing the effectiveness of simulated audio-visual cues for attracting gregarious birds is important for conservation planning. In this study, we (1) assessed whether call playback and decoys were associated with an increased likelihood of Australian fairy terns Sternula nereis nereis visiting potentially suitable nesting habitats; (2) tested their behavioral response to different cues; and (3) documented whether social facilitation had the potential to encourage colony establishment. A full cross-over study design consisting of all possible pairings of decoy and call playback treatments (control [no attractants], decoys, call playback, both decoys and playback), allocated as part of a random block design, was undertaken at 2 sites. Linear modeling suggested that call playback was important in explaining the time spent aerial prospecting as well as the maximum number of fairy terns aerial prospecting, although this only appeared to be the case for 1 of the 2 sites. Decoys, on the other hand, did not appear to have any effect on time spent aerial prospecting. The results from this study suggest that audio cues have the potential to encourage site selection by increasing social stimuli, but attractants may be required over several breeding seasons before colonies are established.
Predicting the distribution of threatened orbicellid corals in shallow and mesophotic reef ecosystems

Published: April 2021

Orbicellid corals are threatened primary reef-building corals throughout the Caribbean in shallow and mesophotic coral ecosystems (MCEs), yet a poor understanding of where they occur limits population monitoring and management. The goals of this study were to predict suitable habitat for orbicellid coral species and to identify how abiotic environmental factors constrain that habitat on the eastern Puerto Rico Shelf. The probability of occurrence for Orbicella annularis and O. faveolata/O. franksi (combined) from shallow to mesophotic depths on the eastern Puerto Rico Shelf was predicted using maximum entropy models. Contributions of abiotic predictors, including bathymetry, seafloor topography, temperature, wave exposure, and bottom velocity, were assessed. Model performance was assessed using area under the receiver operating characteristic curve, standard error of the replicate model runs, and mean absolute error. Both O. annularis and O. faveolata/O. franksi distributions were best predicted by rugosity, temperature, and wave exposure. O. faveolata/O. franksi occurred at shallow and mesophotic depths, and acted as a proxy for identifying the spatial extent of MCEs, contrary to O. annularis, which was predicted at shallow depths. Results for O. faveolata/O. franksi in mesophotic depths indicated potential for large areas of unexplored and unmonitored MCEs along the southeast shelf of St. Thomas, US Virgin Islands and within the Virgin Passage. These spatial predictions of potential mesophotic reef habitats will provide direction for future MCE exploration efforts.

Published: April 2021

Today the environment protection is one of the most important issues in the world. The utilization of accumulating industrial waste is an up-todate area of construction research. The paper suggests a method for processing an electricity production waste, namely an ash from the hydraulic removal in the thermal power plant (TPP). The special classification by fractions of ashes from the hydraulic removal allows to receive such products as iron-containing product, fine sand (coarse filler), aluminosilicate hollow microsphere, and product with pozzolanic activity (fine filler).The experts of the State Enterprise "The State Research Institute of Building Constructions" and "Engineering Company "Perspective"" have conducted a series of studies on the obtained products properties and chemical composition, as well as on determining the fractional composition of each product. The density and specific surface area were evaluated, and each product binding properties control was performed. It was found that the aluminosilicate hollow microsphere and the product with pozzolanic activity had binding properties, and hardened mortars based on these materials were insoluble in water. Chemical analysis showed that in each of the products, except for iron-containing one, oxides of silicon and aluminum predominated. The iron containing product had a high content of iron oxides and by its composition was close to magnetite.The carried-out studies show that the products obtained during the hydraulic ash removal at TPP have a wide range of applications, both in the construction industry and in the chemical, mining, and metallurgical industries. In construction, these materials can be widely used as active mineral additives in the grinding of cements, or as additives improving the concrete mixtures and concretes properties. The iron-containing product is applicable in the special ultraheavy concretes manufacture.

На основании данных литературных источников и исследований авторов, выполнен анализ причин и условий, при которых разжижение линзы или прослойки слабых водонасыщенных грунтов приводит к нарушению устойчивости склонов. В зависимости от своего расположения, линзы разжиженного грунта уплотняются под весом вышележащих грунтов или приходят в движение, что приводит к развитию оползней. Разрушение структуры водонасыщенного грунта происходит в зоне действия критических касательных напряжений и переводит последний из твердого состояния в состояние смеси «грунт–вода», которая имеет все характерные свойства неньютоновской жидкости. В последующем, основная деформация образуется за счет пластического скольжения, которое происходит без изменения объема грунта. Пластическое скольжение продолжает разрушать структуру и приводит к нарушению сплошности грунта.Режим текучести наступает, когда напряжение сдвига превышает силы трения между частицами грунта и структурную прочность τо. Характерной особенностью неньютоновских жидкостей является переменная кажущаяся вязкость, она зависит от температуры, давления, скорости сдвига, продолжительности действия нагрузки и других факторов, но в основном – от скорости сдвига.Проанализированы физические основы нарушения устойчивости склонов при разжижении грунтов в отдельных линзах, в зависимости от их расположения в массиве склона.Приведена уточненная зависимость для определения максимально возможной скорости смещения оползневых масс, перемещающихся по наклонной линзе разжиженных грунтов.

Published: April 2021

The transformation of the demand structure and the level of competition head new trends in a modern society, which cause a significant influence to all subjects of the market economy including forestry. In this connection, security issues gain theoretical and practical relevance. Competitive advantages of forestry relate to different types of security including finance, defense and industry, food, environment, investments. The Article describes characteristics of the above mentioned types of security and facilitates linkages between them and forestry both in conjunction and separately. The practical aspect of economic security of forestry is represented by the analysis of statistics on wildfires, reforestation, as well as a number of identified forestry crimes.
THEORETICAL BASIS OF ECONOMIC EFFICIENCY OF FOREST RESOURCES USE
Authors:   Academy of Management of Internal Affairs of Russia, Moscow, Russian Federation, BULGAKOVA MARINA
Published: April 2021

Modern society operates in an unstable economy, regularly emerging crisis phenomena, the formation of which is facilitated not only by various financial instruments, socio-economic factors, wars, natural disasters, but also by life forms, which spread infections to living organisms, parasitizing and using foreign cells for survival. The present article considers the concepts of «economic growth» and «economic efficiency» in order to identify the theoretical basis for the effective exploitation of forests, as a natural resource whose reserves are declining. The analysis of economic models, including those authored by Nobel Prize winners, made it possible to identify fundamental problems, the implementation of which, in the context of national interests, allows, regardless of the economic structure, to maintain a stable level of economic activity using a natural resource. The economic worldview of contemporaries, the transformation of human behaviors under the influence of forced isolation measures, formalism and the short time frame for finding ideas to overcome crises, contributed to the formation of philosophically oriented theories of the emergence of crisis phenomena in the economy, as well as the lack of a deep study of methods and tools of modern models and theories. Analyzing the structure of forest management in Russia, coupled with approaches to charging for the use of the resource, the author concludes that the ideas of an economic philosophy of efficient forest management were not only developed by the beginning of the 20th century, but also experimentally tested, bringing benefits and results in the form of significant amounts of budget replenishment, subsequently directed to the development of science, technology and the improvement of social security for forestry workers.

3-hydroxybutyrate dehydrogenase-2 (Bdh2), a short-chain dehydrogenase, catalyzes a rate-limiting step in the biogenesis of the mammalian siderophore, playing a key role in iron homeostasis, energy metabolism and apoptosis. However, the function of Bdh2 in embryonic stem cells (ESCs) remains unknown. To gain insights into the role of Bdh2 on pluripotency and cell fate decisions of mouse ESCs, we generated Bdh2 homozygous knockout lines for both mouse advanced embryonic stem cell (ASC) and ESC using CRISPR/Cas9 genome editing technology. Bdh2 deficiency in both ASCs and ESCs had no effect on expression of core pluripotent transcription factors and alkaline phosphatase activity, suggesting dispensability of Bdh2 for self-renewal and pluripotency of ESCs. Interestingly, cells with Bdh2 deficiency exhibited potency of endoderm differentiation in vitro; with upregulated endoderm associated genes revealed by RNA-seq and RT-qPCR. We further demonstrate that Bdh2 loss inhibited expression of multiple methyltransferases (DNMTs) at both RNA and protein level, suggesting that Bdh2 may be essentially required to maintain DNA methylation in ASCs and ESCs. Overall, this study provides valuable data and resources for understanding how Bdh2 regulate earliest cell fate decision and DNA methylation in ASCs/ESCs.
