Simulation analysis of biomass pyrolysis based on the improved CPD model with chain reaction dynamics
Authors: Chen Bin , Yuan Mengxue , Wang Sha , Shen Jun , Guo Yun
Published: December 2021

The complex composition and molecular structure of biomass lead to more
complex and diversified chemical reactions in the pyrolysis. According
to the structural characteristics of the reactants, this paper
simplifies the pyrolysis process and extends the research focus from the
micro-molecular elementary reactions to the macro reaction kinetics. The
wheat straw is chosen as the investigated biomass, and the promoted
chemical percolation devolatilization (CPD) with modified pseudo-grid
and chain reaction kinetics (CRK) pyrolysis models were constructed for
predicting the pyrolysis characteristics. Compared with the experimental
results, the prediction errors of char, oil and gas production are in a
reasonable range of < 10 %. Moreover, the reliability of the
model is verified by comparing with the experimental thermogravimetric
curve, which shows that the model could well predict the mass loss,
product distribution and component characteristics, and provides a
reasonable prediction for the pyrolysis of biomass.
A Comprehensive Review of Cerebral Oximetry in Cardiac Surgery
Authors: Moore Christina , Yu Soojie , Aljure Oscar
Published: December 2021

Background: Patients who undergo cardiac surgery are at increased risk
of stroke, postoperative cognitive decline, and delirium. These
neurocognitive complications have led to increased costs, intensive care
unit stays, morbidity, and mortality. As a result, there is a
significant push to mitigate any neurological complications in cardiac
surgery patients. Near-infrared spectroscopy to measure regional
cerebral oxygen saturations has gained consideration due to its
non-invasive, user-friendly, and relatively inexpensive nature. Aim of
Study: To provide a comprehensive summary of cerebral oximetry in
cardiac surgery. The review interrogates multiple systematic reviews
assessing different outcomes in cardiac surgery to assess if cerebral
oximetry is effective. Further, the review analyzes all available
interventions for an acute desaturation to determine the efficacy of
individual interventions. Methods: A narrative review of randomized
controlled trials, observational studies, and systematic reviews with
metanalyses were performed through August 2021. Results: There is
significant heterogeneity amongst studies regarding the definition of a
clinically significant cerebral desaturation. In addition, the
assessment of neurocognitive outcomes has large variability, making
metanalysis challenging. To date, cerebral oximetry use during cardiac
surgery has not been associated with improvements in neurocognitive
outcomes, morbidity, or mortality. The evidence to support particular
interventions for an acute desaturation is equivocal. Conclusions:
Future research is needed to quantify a clinically significant cerebral
desaturation and to determine which interventions for an acute
desaturation effectively improve clinical outcomes.

Authors: Miyashita Hirokazu , Moriyama Noriaki , Yamanaka Futoshi , Saito Shigeru , Lehtola Heidi , Piuhola Jarkko , Niemelä Matti , Laine Mika
Published: December 2021

Objective: The implantation depth and membranous septum (MS) length are
established as the predictors of new-onset conduction disturbance (CD)
after transcatheter aortic valve replacement (TAVR) for tricuspid aortic
valve (TAV) stenosis. However, little is known about the predictors with
bicuspid aortic valve (BAV). This study investigated the role of MS
length and implantation depth in predicting CD following TAVR with a
balloon-expandable valve in patients with BAV. Methods and results: This
retrospective study analyzed 169 patients who underwent TAVR for BAV
with balloon-expandable valve, and TAV cohort was established as a
control group using propensity score (PS) matching. The primary endpoint
was in-hospital new-onset CD (new-onset left bundle branch block or new
permanent pacemaker implantation). New-onset CD developed in 37 patients
(21.9%). Multivariate analysis revealed severe LVOT calcification (Odds
ratio [OR]: 5.83, 95% confidence interval [CI]: 1.08 – 31.5, p
= 0.0407) and implantation depth – MS length (OR: 1.30, 95% CI: 1.12
– 1.51, p = 0.0005) as the predictors of new-onset CD within BAV
cohort. The matched comparison between BAV and TAV groups showed similar
MS length (3.0 vs 3.2mm, p = 0.5307), but valves were implanted deeper
in BAV than TAV group (3.9 vs 3.0mm, p < .0001). New-onset CD
was more frequent in patients having BAV (22.3% vs 13.9%, p = 0.0458).
Conclusion: The implantation depth - MS length, and severe LVOT
calcification predicted new-onset CD following TAVR in BAV with
balloon-expandable valve. High implantation technique could be
considered to avoid new-onset CD in BAV anatomy.

Published: December 2021

Background: Data on disease burden of respiratory syncytial virus (RSV)
associated acute lower respiratory infection (ALRI) among young children
are limited in China. This study aimed to estimate the hospitalization
rate of RSV-associated ALRI (RSV-ALRI) among children aged
0~59 months in Suzhou, China. Methods: We
retrospectively identified all hospitalized ALRI children aged
0~59 months in Suzhou University Affiliated Children’s
Hospital during January 2010 to December 2014. Detailed diagnosis and
treatment data were collected by individual medical chart review.
Referring to WHO influenza disease burden estimation method, we
estimated the hospitalization rate of RSV-ALRI among children aged
0~59 months in Suzhou, China. Results: Among 28,209 ALRI
cases, 19,317 (68.5%) were tested for RSV and the RSV positive
proportion was 21.3% (4,107/19,317). The average hospitalization rate
of RSV-ALRI for children aged 0~59 months was 14 (95%
confidence interval [CI]:14~14)/1,000
children-years, for children aged 0~5,
6~11, 12~23, and 24~59
months were 70 (95%CI: 67~73), 31 (95%CI:
29~33), 11 (95%CI: 10~12), and 3
(95%CI: 3~3) /1,000 children-years, respectively.
Conclusion: There is considerable RSV-ALRI hospitalization among
children aged 0~59 months, particularly among children
aged <1 years. An effective monoclonal antibody or vaccine is
urgently needed to address the substantial hospitalization burden owing
to RSV infection. Key words: Respiratory syncytial virus,

Authors: Prariyadiyani Janati , Kurniawan Andri , Baiquni M.
Published: December 2021

Seiring pesatnya kemajuan teknologi transportasi yang terjadi sejak abad ke-20, jalan tol menjadi kebutuhan yang tidak terelakkan. Di sisi lain, kebutuhan lahan untuk pembangunan jalur tol dan sarana pendukung lainnya, begitu pula perubahan pada jaringan jalan yang sudah ada, tidak dapat meniadakan dampak terhadap lingkungan sekitarnya. Salah satu dampak yang harus diperhitungkan akibat pembangunan Jalan Tol Solo-Yogyakarta di wilayah Kecamatan Kalasan, Sleman, Daerah Istimewa Yogyakarta (DIY) ada hubungannya dengan potensi arkeologi yang dimiliki kecamatan ini.Sejumlah tinggalan arkeologi Periode Klasik berupa candi Hindu atau Buddha yang sudah ditetapkan sebagai Cagar Budaya (CB) belum menggambarkan keseluruhan potensi yang ada. Banyak data yang masih terkubur mengingat bahwa setiap candi pasti memiliki komponen pendukung di dalam lingkungan binaan masa lalu. Komponen tersebut dapat berupa sisa bangunan lain struktur, maupun temuan lepas yang terkubur oleh material hasil erupsi Gunung Merapi selama ratusan tahun. Artikel ini berusaha memprediksi dampak positif dan negatif pembangunan Jalan Tol Solo-Yogyakarta terhadap seluruh potensi arkeologi berdasarkan tiga kriteria, yakni: terdampak langsung (oleh pembangunan jalan tol dan fasilitas pendukung), terdampak tidak langsung (oleh perkembangan jalan lain), dan tidak terdampak. Melalui analisis keruangan masing-masing kriteria tersebut dipetakan sebagai hasil penelitian yang bersifat prediktif. Beberapa rekomendasi dirumuskan sebagai masukan bagi pihak-pihak terkait yang bergerak di bidang penelitian, pelestarian warisan budaya, serta pemerintah daerah setempat.

Bencana longsor terjadi pada Februari 2017 yang berdampak pada beberapa wilayah diantaranya Banjar Bantas Desa Songan A dan B, Banjar Yeh Mampeh Desa Batur Selatan, Banjar Awan Merta di Desa Awan, Banjar/Desa Sukawana, dan Banjar/Desa Subaya. Lokasi kejadian terparah berada pada Banjar Bantas Desa Songan A dan B serta di Banjar Yeh Mampeh, Dalam penelitian ini, akan dicoba untuk membuat studi analsis potensi bencana tanah longsor pada wlayah kaldera batur purba dengan metode pembobotan dengan mengacu pada Peraturan Menteri Pekerjaan Umum No. 22/PRT/M/2007 tentang Pedoman Penataan Ruang Kawasan Rawan Bencana Longsor. Untuk mengetahui potensi longsor di daerah Kaldera Batur Purba, dalam penelitian ini menggunakan teknik analisis deskriptif korelatif dan deskriptif kompartif. Meskipun ketiga komponen lainnya memiliki kepekaan yang tinggi terhadap gerakan tanah, curah hujan tahunan yang kecil membuat daerah Kaldera Batur hanya berada pada kelompok sedang. Namun, ketika curah hujan harian atau bulanan mengalami peningkatan drastis, potensi terjadi bencana longsor akan meningkat menjadi sangat tinggi karena faktor penyebab longsor selain curah hujan semuanya termasuk sangat peka terhadap erosi. Oleh karena itu, bencana longsor patut diwaspadai ketika daerah kaldera Batur masuk ke dalam musim hujan. Kejadian ini biasa terjadi sekitar bulan Desember-April.

Published: December 2021

A methodical approach to the formation of indicators of the information base of management decisions on the development of freight JSC “Ukrzaliznytsia”, which consists in calculating the taxonomy of the level of development of freight by substantiating systems and its elements: eighteen static systems, elements of which are six regional railways; seven dynamic systems – regional branches and in general JSC “Ukrzaliznytsia”. A spatial and temporal comparison of the development of freight transportation of selected systems is carried out. The taxonomy index is calculated on the basis of five indicators of freight traffic for the period 2002-2019. The analysis of static systems made it possible to identify the uneven development of freight transportation of regional branches of JSC “Ukrzaliznytsia” for the studied 18 years. The temporal comparison of the levels of development of freight traffic by each railway in particular also showed their instability. Fluctuations are observed in the last three years of the study period. In 2018, JSC “Ukrzaliznytsia” demonstrated the lowest level of freight transportation development for the entire analyzed year 2002-2019. It was established that both external and internal factors caused the negative impact on rail transportation, in particular: the economic crisis of 2014-2015; military action in eastern Ukraine; ineffective management at different levels of government. The introduction of quarantine measures due to the COVID-19 pandemic caused unprofitable and deteriorating financial and economic performance of JSC Ukrzaliznytsia, and its six regional branches in 2020, in particular, revenues from freight transportation decreased by 10.3% compared to 2019, and net loss amounted to UAH 11.9 billion. Implementing the anti-crisis plan by the management of JSC Ukrzaliznytsia and the improvement of operational work in the freight segment has yielded some positive results. However, for the effective planning and management decisions in the field of freight transportation an important component is the proper formation of an information base. The proposed methodological approach will serve as an effective tool not only in the management of the freight segment of individual regional branches or enterprises in particular, but also the economic development of JSC “Ukrzaliznytsia” in general and can be used by other large companies.

The choice of strategy ensures the formation of a certain option that provides a detailed analysis of situations that may arise in the future. As in the game, where each of the participants plans their actions, predicting the actions of other players and the general conditions of situations that may arise as a result of these actions. You should pay attention to the probability of committing players and the probability of a certain situation. It is clear that this is a prediction of a situation that has not yet occurred, but occurred in accordance with the probability of the strategy in the implementation of the actions of each of the participants associated with the risk. The application of the principles, methods and tools of game theory will make it possible to form a complete plan of action in all situations that are expected to occur. The developed action plan of the participants (players, subjects) in accordance with the whole set of situations and possible developments in them, forms a strategy. Game theory is based on the application by each participant of a single strategy, which is a certain algorithm of actions, not a list of them. Such an algorithm, due to its branches, should reflect the possibility of occurrence and development of events and situations. The article proposes methods of selecting and evaluating enterprise strategies through the application of game theory, which will take into account the strategies of competitors (other participants in the conflict situation) or the state of "nature", which embodies the environment of enterprises. The article considers the advantages and disadvantages of using game theory methods to evaluate enterprise strategies, classifies and compares the types of these methods to clarify the peculiarities of their application in certain situations, the peculiarities of the application of strategy selection criteria in this scope.

Authors:   Lviv Polytechnic National University, Chornopyska Natalia , Stasiuk K. ,   Lviv Polytechnic National University
Published: December 2021

The article emphasizes Ukrainian terminology streamlining importance for the area of logistics and supply chain management. It is noted that cooperation of linguists-terminologists and logistics specialists should be considered as a prerequisite for terminological work of high quality. First group’s responsibilities include elaboration and presentation of the term resulting into reducing its semantic content by fitting the scope into boundaries of vocabulary definition; logistics professionals on the other hand are responsible for developing scientific discourse maximizing scientific concept contents. Logistics terminology problem gets into focus of every searcher researching logistics and supply chain management problems. Exploration results are rather representing semantic content of a term than polishing it by aiming at unambiguous and clear definition of the term, its conciseness. The streamlining of Ukrainian terminology in logistics is likely to draw experts’ attention to qualitative component of the problem concerning terms unification. And it seems reasonable to start with common terms, such as "logistics potential" being the object of this study. The paper aims at supplementing the scientific discourse on the term "logistics potential" with its subsequent unification. General objectives include (1) carrying out a comparative and critical analysis for the scientific concept of "logistics potential" by means of existing developments of domestic scientific schools and (2) proposing unified term for "logistics potential" suitable for further codification in the terminology dictionary. As a result, a visual representation of "logistics potential" concept is being provided; the author's definition of the term "logistic potential" is being formulated; the need for "logistics system", "capability", "symbiosis", "resilience" and "progress" categories usage is being explained as the most suitable for revealing the content as well as helpful for achieving conciseness of the term.
Development of customs infrastructure on the Ukrainian –Polish border in the conditions of business internationalization
Authors:   Lviv Polytechnic National University, Adamiv Marta , Ruda Mariana ,   Lviv Polytechnic National University
Published: December 2021

The relations between Ukraine and Poland represent a long history of partnership and have a great economic importance for both countries. At the present stage, Poland is one of the largest international trade partners of our country. In the history of Ukraine's foreign trade during 2019-2020, Poland occupied second place in the structure of domestic exports. Thus, in 2020 the share of exports of Ukrainian goods to Poland was 6.65%. First of all, it means a change in the vector of foreign trade development for the national economy and the reorientation of Ukraine's export market to the European Union. In 2020, Poland also occupied one of the leading positions in the structure of Ukrainian imports of goods (4th place with a share of 7.62%). This situation leads to a significant increase in the load at checkpoints and causes the need to ensure prompt and efficient customs clearance of goods moving across the Ukrainian-Polish border. On the basis of the performed researches, significant differences in the levels of development of the customs services of Poland and Ukraine in terms of the quality of customs services have been established, as Ukraine lags far behind Poland in all the studied indicators in this area. Such situation requires the improvement of the work of Ukrainian customs authorities in the context of business internationalization, including the development of customs infrastructure in the area of the Ukrainian-Polish border. The key problems of customs service of enterprises at domestic checkpoints include long and costly customs procedures, lack of proper technical, road, information infrastructure at checkpoints, outdated technical instruments of customs control, etc. It is proved that in the conditions of business internationalization one of the key tasks should be the construction of new checkpoints and the development of the customs infrastructure of the existing checkpoints. The key strategically important checkpoints in the area of the Ukrainian-Polish border, which need to be modernized in order to increase their capacity, include road checkpoints "Korchova-Krakivets", "Dorokhusk-Yagodyn", "Medyka-Shehyni", as well as a railway checkpoint "Medyka-Mostyska". In addition, the importance of spreading the practice of construction of joint checkpoints, which allows to significantly speed up the process of customs services for businesses, was emphasized.

Authors:   Lviv Polytechnic National University, Duma Oleh
Published: December 2021

The article presents the results of a scientific research the features of the Scandinavian model of technology transfer, which has demonstrated its effectiveness in Norway, Sweden and Finland. The Scandinavian model of technology transfer has been formed for a long time and has been subject to significant experiments by the governments of these countries, research centers, universities and business structures, which sought an effective model of organizing the innovation process from the perspective of their own goals and interests. The article presents the results of the functioning of technology transfer in the innovation ecosystem of these countries, through their place in the international rankings of innovations and related rankings. It is proposed to use a six-criteria scale to assess the effectiveness of technology transfer, which contains: Human development index, Global knowlede Index, Doing business, Global Innovations Index, The Global Competitiveness Index, The International Property Right Index. The results of the innovation ecosystem of countries have their expression in micro- and macroeconomic indicators. Most of these indicators are taken into account when ranking countries in one or more indices proposed for six criteria scale. Assessing the condition of technology transfer through these six criteria scale makes it possible to determine the productivity and level of organization of technology transfer in the country. The article analyzes the peculiarities of the functioning of technology transfer mechanisms in Norway, Sweden and Finland. The analysis revealed that the three countries studied have their own preconditions and priorities for the development of the innovation ecosystem. Nevertheless, there are a number of features that are common and fundamental for effective technology transfer in each. One of the important elements of effective technology transfer in the Scandinavian countries are universities and technology transfer centers in universities. Therefore, the article also explores the functions and tasks of technology transfer centers in Scandinavian universities. The peculiarities of the Scandinavian model, which determine its efficiency, have been researched, on the other hand, this peculiarities can and should be implemented in the Ukrainian practice of technology transfer

Management consulting in Ukraine is used sporadically in contrast to European countries, cooperation with consultants regularly. The reason is that the vast majority of companies, firms, and companies seek advice in critical situations when their own efforts are simply no longer able to solve existing problems. The authors identified the state of the consulting industry and the main providers of consulting services in the domestic market, provided auditing information, and identified several contradictions and problems of auditing; the number of registered auditors on the territory of Ukraine for 2016-2020 and their structure by regions in 2019 and 2020 were studied as well. The article forms the main trends of the European consulting market in 2021: digitalization, individual decisions, a strategy that moves within the company, high return on investment, growing demand for the technology sector, and restructuring practice. In general, the consulting industry has suffered a significant blow from the Covid-19 crisis, and, according to the latest data, at the end of 2020, it was about 18% lower. However, the prognosis is improving in many European countries as they manage to reduce the number of new coronavirus cases. According to this data, the authors suggest that domestic companies should follow practices: focus their activities on crisis management, quickly adapt customer business to modern conditions, accelerate the pace of digitalization, and use innovations to update strategies.

The paper examines the main types of intellectual property rights, which might be violated in the media space (Internet, radio, TV, press). In today's world, the media has long been a major source of information. As the amount of information in the media increases, so does the amount of intellectual property involved. The most fundamental form of intellectual property protection technology is the control of access to information (ie determining whether the requester is allowed access to information). However, the existing access control offers only part of what is needed to work with intellectual property. So, it is not always protected at the legislative level, and the context in which it is used often does not benefit the owner. The intellectual property right infringement requires deep analyzes of the current situation, exploring and offering concrete solutions for each particular kind of infringements. Thus, the aim of the work is to study, analyze and identify problems of infringement of intellectual property rights in the media space, ways to prevent and combat them. The ways of offenses prevention are widely describe in the paper. Possible infringements of intellectual property objects on the Internet, on television and radio are analyzed in the paper; the legislative basis for protection of intellectual property rights and statistics in cyber attacks in 2020 in the world are deeply analyzed. The methods of protection of intellectual property rights of various types, including, such as coding of websites, a watermark and others are ofefred. The activity plan based on process of registration of the intellectual property right and solution of problems with infringers are investigated and offered in the paper. The importance of media impact in the sphere of intellectual property is described on the example of presidential campaign in USA. Recommendations for: identifying the need to protect intellectual property, improvement of existing administrative measures for the development and protection of intellectual property are investigated in the paper and are of practical value.

Accelerated population growth, depletion of natural resources, excessive pollution of the environment, which threatens the existence of mankind, was a prerequisite for the emergence of the concept of circular economy and the principles of sustainable development, ie doing business without harm to the environment. The model of circular (circular) economy is aimed at energy saving, regenerative environmentally friendly consumption and production. The article presents the results of the study of the concept of circular economy and the benefits of its implementation based on the experience of the European Union - a global leader in this field. The main goals, priorities and measures of the EU in the implementation of the circular economy are revealed. The basic principles of the circular economy are highlighted, examples of successful use of its business models are given. The two most acute global problems that can be solved only by a closed-loop economy are identified, and forecasts of the results of its global use are given. Closed-loop economics is a concept of resource management that is rapidly gaining global popularity and is recognized in the scientific literature as one of the key drivers for achieving objectives of the Paris Agreement. 30 years have passed since the first mention of the "circularity" of the economy, however only after its official introduction in the EU its popularity has grown rapidly, and world leaders have gradually been realizing its importance for achieving sustainable development. Climate change and depletion of natural resources are the visible negative processes that require the implementation of a circular economy. At the same time, society itself must change – from the choice of raw materials, product development methods and new concepts of service to the widespread use of by-products of one industry as complete raw materials for another. This requires the training of relevant specialists, whose professional activity will be the circular economy.To date, the most significant results in the transition to a circular economy are demonstrated by the European Union (EU), where the European Resource Efficiency Platform, which brings together EU countries, aims to ensure the transition to a circular economy based on reuse and high-quality recycling. Circular economy is a new trend that is seen as an important area of structural reform and aims to raise awareness of the real environmental, energy and socio-economic situation of the world by identifying ideological options for a better understanding of the dilemma of economic growth vs. the environment, optimal ways and more effective tools for solving problems, faced by society. The goal of the circular economy is to ensure, in line with the global CSWs, a shift towards sustainable production and consumption while integrating environmental issues into the adoption process solutions.
