Low Emission Areas vs. Urban Congestion Taxes
Authors: Castillo López José Manuel
Published: June 2023

In most European cities, urban transport is responsible for the majority of energy consumption, the emission of pollutants into the air, traffic congestion and noise, and in the last century we have faced an increase in urban mobility and a growing tendency to use private, as opposed to public transport, and an increase in the number of vehicles. The strictly private economic rationality of citizens explains this trend and the market will regulate it, albeit with largely avoidable social costs of congestion. Supply policies, that is, more and more extensive routes, are those that have been carried out almost exclusively traditionally, but these have been insufficient and, paradoxically, have even caused effects contrary to those intended, in the light of the state of empirical experiences, not to mention the waste of public resources that may be destined for more socially profitable alternative uses. As a consequence, where there is the greatest room for manoeuvre for urban transport policy is found in demand, that is, in the use of available means of urban transport. In recent decades, a good number of partial demand measures have been tried in European cities, such as subsidies for buses and subways, ecological fuels, car-sharing, smart cards, road-pricing, park-pricing, one day without a car, distribution of departure times at the end of the working day, etc. This paper focuses on Road Pricing, pointing out the experiences of the cities in which it has been put into practice but, mainly, examining its economic foundation and the design that should inspire collaboration in terms of achieving a more efficient and socially equitable urban mobility model. Keywords: Taxes; Automobiles; Highways; Payments; Urban congestion; Polluters.
News and Perspectives of Public Law
Authors: Ştefan Elena Emilia
Published: June 2023

Since the earliest classic division of law into public law and private law, envisioned by the 3rd century Roman legal expert Ulpian, interdisciplinarity as a fundamental feature of the law has currently become noteworthy. The recent exceptional pandemic situation that we have faced, which can easily be regarded as “crisis,” has revealed once more that reference to society can only be made by resorting not only to law but also to ethics and morals. Public authorities have often found themselves in the position of making administrative decisions for the population, objected by the great majority, as fundamental rights have been restricted for short periods of time. This paper addresses a current topic of interest, namely Considering interdisciplinarity, can we speak nowadays of a new public law? If so, what should we do with the old law? Should we discard it or rebuild it? These questions are answered herein by using research methods specific to law, in order to emphasise the conclusions according to which the measures for good administration carried out by public authorities must express both the letter of the law and the spirit of the law, taking the general interests of society into account. Keywords: Public law; Public Interest; European Ombudsman; Maladministration; The Venice Commission.
Religion and Belief Discrimination at Work: Legal Challenges in the UK
Authors: Lazăr Ioan
Published: June 2023

The importance of corporate social responsibility (CSR) activities has increased in recent years. More undertakings active on different markets are becoming aware of the importance of improving labour policies, investing in safety training of employees, environmental protection, local community-related projects, volunteering, and charitable activities. At issue is whether higher degrees of competition associated with periods of economic crisis will affect the degree of competition on the market in a favourable or a non-favourable manner. Based on statistical data currently available, this paper will analyse whether higher levels of competition will increase investments in CSR activities to create trustworthy firms that will survive even in economically harsh periods, or will otherwise reduce the aforementioned types of investments and thereby facilitate the flourishing of anticompetitive practices on the market. This paper will first start with a short presentation of the concept, importance and meaning of corporate social responsibility, followed by considerations related to the importance of ethics in competition law. Finally, the author will analyse the impact of competition on CSR-related activities and the ways in which the pressure of competition can impact on CSR investments. Keywords: Corporate social responsibility; Competition; Anticompetitive practices; CSR activities; CSR investments
Non-dermatological interests of well-known dermatologists
Authors: Korkhov S.S. , Lebediuk M.M.
Published: June 2023

In the turmoil of everyday life, in a series of events determined by the struggle between the concepts of «want» and «should», we look forward to the moment when there will be an opportunity to take up our favorite business. And it is inspiring because a hobby is something we do purely for pleasure.It is difficult to imagine a person who does not have any hobbies. In our historical research, we focused on interests, hobbies and preferences that go beyond the main work of more than one hundred well-known dermatologists, venereologists and some other specialists associated with dermatovenereology. For the most adventurous of them, such hobbies became an integral part of life, a key to the complex labyrinths of their spiritual world, a mirror of their worldview, a tuning fork of their morality.The names of most of the people mentioned in the article are inscribed in golden letters in the history of medicine and dermatovenerology in particular. They made many scientific discoveries, their brilliant clinical experience helped to heal and alleviate the suffering of a huge number of patients, they are talented teachers who generously shared their knowledge with their students. At the same time, most of them had high civic qualities.We have tried to reveal little-known pages of the lives of our esteemed colleagues. We modestly peeked behind the scenes to better see and appreciate what was happening on the main stage.So, the presented material is about our outstanding colleagues and their hobbies, banal, remarkable and diverse: love for painting, music, literature; collecting; passion for sports and other options for active pastime; extraordinary, exotic preferences and other things that can hardly be considered as hobbies which for some of our colleagues became perhaps more important than the medical vocation.
Valorisation of eyewear bioplastics through HTC and anaerobic digestion: Preliminary results
Authors: Marchelli Filippo , Ferrentino Roberta , Ischia Giulia , Calvi Marco , Andreottola Gianni , Fiori Luca
Published: June 2023

Bioplastics are increasingly replacing traditional plastics in many sectors, but the legislative and operative frameworks for their disposal remain unclear: they should be collected and treated together with the organic fraction of municipal solid waste (OFMSW), but often do not biodegrade satisfactorily in the plants that treat OFMSW. This work focuses on a type of cellulose diacetate employed in the eyewear industry to analyse hydrothermal carbonization (HTC) as a pre-treatment before anaerobic digestion (AD). The results show that HTC can hydrolyse this bioplastic even at moderate temperatures, reaching an almost total dissolution in the liquid phase at 210 °C and, at higher temperatures, producing hydrochar. When the HTC slurry obtained at 210 °C is fed to mesophilic or thermophilic AD, both the amount and the production rate of biogas are enhanced compared to the raw bioplastic. In particular, in thermophilic conditions, the amount of produced biogas undergoes at least a threefold increase compared to the untreated cellulose diacetate. Thus, this work confirms that a prior HTC step may be a suitable approach to enhance the disposal and energy recovery of bioplastics through AD.
Simultaneous removal process of hydrogen sulfide and siloxanes and field application of iron hydroxide desulfurization agent for green hydrogen production from biogas

Published: June 2023

Biogas, one of renewable energies, is a key element necessary for a carbon-neutral policy and to build a hydrogen economy. In order to utilize biogas, impurities of biogas such as moisture, hydrogen sulfide(H2S), siloxanes, and VOCs should be removed. In particular, since H2S causes corrosiveness of equipment by sulfur oxides, and is harmful to the human body if leaked, it is a major target material to be removed. The minimum concentration of H2S obtainable from the wet method is several ppm. It is known, however that the iron hydroxide-based adsorbent in the dry method can obtain ultimately low concentration of H2S down to 0.1 ppm or less. The DeHyS was manufactured through a series of processes such as mixing iron cloride solution or iron sulfate solution, NaOH solution, and inorganic binder. During the adsorption process, H2S was removed in the form of iron sulfide through a chemical reaction, and siloxanes are known to be removed through physical adsorption. It was also applied to various biogas plant sites such as landfill gas, sewage sludge, livestock manure, and food waste. At this time, the H2S removal efficiency was known to be 99.9% or more, while simultaneous removal of 90% or more of the total siloxanes was possible. Moreover, the biogas produced at the Chungju Food Bioenergy Center was pretreated using the DeHyS and supplied to the nearby Chungju Bio Green Hydrogen Charging Station to produce hydrogen through steam methane reforming(SMR), producing 500 kg of hydrogen from 8,000 m3 of biogas per day.

Authors: Yurkovych Nataliya , Mar’yan Mykhaylo , Opachko Magdalena , Seben Vladimir
Published: June 2023

Formulation of the problem. At the present stage of the development of science education and information technology, their integration, complementarity, and implementation are essential. Therefore, the search for methods of teaching natural sciences, based on the principles of self-organization and computer modeling, corresponds to the immediate tasks of the present.
Materials and methods. Methods of comparative analysis, computer modeling, and generalization strategy are used. The study is based on the physics course content and the use of the programming language.
Results. An innovative fractal approach to the teaching of physical and mathematical disciplines is proposed as a method of improving independent and creative computer modeling of natural phenomena. The fundamental principles of object-oriented programming (encapsulation, inheritance, polymorphism) have proven to be influential in shaping the physical and mathematical aspects of the information architecture of the perception of educational disciplines. The possibility of using this approach in other sections of physics is demonstrated. The developed iterations of the fractal structure are presented in the example of the study of the "Geometric Optics" and "Wave Optics" sections of physics. It is shown that each iteration is characterized by synergy: the addition of a new iteration provides a high-quality and in-depth perception of new information.
Conclusions. The formation of the specified integrated fractal structure conditions the integrity of information perception and its formation happens intuitively. The analysis of the conducted studies confirmed the innovativeness and effectiveness of the fractal approach. This approach can be used to develop systems for the processing and transmission of information, intelligent information materials, and artificial intelligence.

Authors: Hadi Al Ghozali Isnen , Shiddiq Antarressa Mohammad , Samidi Samidi
Published: June 2023

Microservices architecture, a distributed framework architecture that allows changes to one module without interfering with other modules. The implementation of this architecture has its own challenges. The get-list-attachment API running on this architecture takes an average of 12.5 seconds to serve data. This needs to be considered because business processes require shorter access times to support decision making. The research objective is to obtain query response time efficiency for accounting applications. To achieve this, the research uses database optimization techniques with logic execution optimization microservices architecture. This study obtained the source of information from the Accounting Harmony Accounting Module, which has an API (get-list-attachment) with data sourced from Service Accounting (581253 records) and Service Users (2182 records). Based on a series of tests carried out, several services need to be added with APIs to improve the microservices architecture to accept bulk parameters that generate a list of objects so that data presentation is more optimal. After doing a series of engineering on microservices architecture and indexing application, query response time performance increased by 49.22% for Service Accounting module.

Authors: Pertseva T. O. , Gabshidze N. O.
Published: June 2023

The aim of the study was to identify the risk factors for thrombotic events in individuals who have experienced community acquired pneumonia associated with COVID-19 and did not have thrombotic events during the acute period of COVID-19. Materials and methods. 45 individuals were examined in postCOVID-19 period (age - 61.0 (54.0; 68.0) years, males - 22 (48,9 %), females - 23 (51,1 %)). All patients were examined twice: at visit 1 — 45,0 (40,0; 60,0) days from the onset of COVID-19, and at visit 2 — 150,0 (117,5; 160,0) days from the onset of COVID-19. Depending on whether the patients received anticoagulant therapy during post-COVID-19 period, the main group was divided into two subgroups: subgroup 1 included 25 (55,6 %) individuals who received anticoagulants during post-COVID-19 period (the course of acute COVID-19 was moderate in 7 (28,0 %) individuals, and severe or critical in 18 (72.0 %) individuals); subgroup 2 included 20 (44,4 %) individuals who did not receive anticoagulants during post-COVID-19 period (the course of acute COVID-19 was moderate in 12 (60,0 %) individuals and severe in 8 (40,0 %) individuals). Clinical methods, pulse oximetry, laboratory and instrumental methods as well as assessment of the probability of thrombosis according to the Wells and Padua scales were used. Results. There was not any thrombotic event occurred in subgroup 1 during post-COVID-19 period. The duration of anticoagulant use in patients from subgroup 1 was 63,0 (60,0; 90,0) days from the onset of COVID-19 symptoms. In subgroup 2, thrombosis was detected in 5 (25,0%) patients during post-COVID-19 period (4 patients had pulmonary embolism and 1 patient had a combination of pulmonary embolism and acute ischemic stroke). Thrombotic events had occurred before visit 1, at 40,0 (33,0; 45,0) days from the onset of COVID-19, which corresponded to 16,0 (15,0; 18,0) days after the end of anticoagulant therapy. Age, gender, body mass index, and comorbidities (hypertension, obesity, diabetes) were not associated with the occurrence of thrombotic events. Risk factors included severe COVID-19 (p=0,04) and the presence of hereditary thrombophilia. Conclusion. The risk of thrombosis in post-acute COVID-19 period is higher in patients after severe course of the acute period of COVID-19, in the absence of anticoagulant therapy during the post-COVID-19 period. On the other hand, the administration of anticoagulants during at least two months from the onset of COVID-19 symptoms, decreased the risk of thrombosis in the post-COVID-19 period not only in patients with severe course but in patients with critical course of the acute period of COVID-19 as well. Key words: COVID-19, post-COVID-19 period, thrombosis, pulmonary embolism, anticoagulants.
TRAUMATIC PNEUMONITIS DUE TO COMBAT CHEST INJURY AS A RISK FACTOR FOR PNEUMONIA
Authors: Yakovenkо O. К.
Published: June 2023

The relevance of the problem of gunshot wounds and injuries as a result of the war with Russia continues to grow. Gunshot wounds and chest injury can cause several life-threatening conditions: bleeding, airway obstruction, tension pneumothorax with pericardial tamponade, open pneumothorax, massive hemothorax, chest dissection, tracheobronchial injury, diaphragm damage, myocardial injury, rupture thoracic aorta, esophageal damage and lung contusion. Lung contusion or traumatic pneumonitis is characterized by hemorrhage and swelling in the alveoli. This causes respiratory distress which develops 24 hours after lung injury, causing perfusion/ventilation mismatch by increasing pulmonary vascular resistance and decreasing lung compliance. From February 24, 2022 to February 18, 2023, in the Pulmonology Department of Volyn Regional Clinical Hospital, the rate of hospitalized military patients with chest injury due to mine-explosive wounds, shrapnel wounds, gunshot bullet wounds, and stub-cut wounds of the chest amounted to 19.3% of all pulmonary cases among military, admitted this year (n=88). Penetrating chest injury occurred in 41.1% of cases, nonpenetrating blunt chest injury (including behind armor blunt trauma) in 23.5 % of cases, chest trauma with soft tissue injury in 35.2 % of cases. Chest injury with fractured chest bones was detected in 47% of cases. In 52.9 % of cases, chest injuries and one stab-cut wound were on the side surface and chest, which was not protected by a bulletproof vest. Lung contusion or traumatic pneumonitis was observed in 70.5% of cases, including destruction in 29.4 %. Post-traumatic pneumonia was observed in 58.8 % of cases, that was caused by a non-hospital and hospital infection, pleurisy was observed in 17.6 % of cases. After chest injury, infiltrative-destructive pulmonary tuberculosis was detected in 5.8 % of cases and invasive pulmonary aspergillosis in 5.8 % of cases. Thus, the occurrence of a specific infection that can lead to destruction and aggravate destructive changes in the lung parenchyma should also be taken into account. Also, in 64.7 % of cases, metal, fragmentary, foreign bodies of the chest organs were found, and required further surgical removal. The article presents clinical cases of patients with chest injuries received as a result of military operations in Ukraine. Key words: traumatic pneumonitis, lung contusion, gunshot wound, chest injury, behind armor blunt trauma, pneumonia.

For patients who survived a new coronavirus infection, rehabilitation measures are necessary to relieve the sequela of the disease. The article summarized literature data with a rationale and expected outcomes of ozone therapy in patients with post-COVID-19 syndrome. The presented clinical case demonstrates the effectiveness of intravenous ozone therapy as a part of rehabilitation program in patient with community-acquired polysegmental pneumonia associated with the SARS-CoV-2 virus. The use of this technique (combination of the infusion of ozonated saline and ozonated saline saturated with the patient’s blood) allows to reduce the activity of the inflammatory process, which contributes to the complete restoration of physical exercise tolerance and the improvement of the patient’s quality of life. Key words: COVID-19, pneumonia, rehabilitation, ozone therapy
Quantitative Analysis of Fuel Consumption and Fuel Sediments Separation as a Function of Fuel Type and Ship Operation Mode on Product/Chemical Tanker Example
Authors: Dujmović Josip , Miculinić Rikard
Published: June 2023

Fuel consumption onboard is influenced on several factors but most crucial is ship operation mode and fuel type in use. Conventual fuel preparation process onboard consists of several stages. One of the most essential processes is centrifugal separation treatment operation onboard, which consists of introducing fuel into the field of high centrifugal field, where impurities and sediments are separated from fuels. The quantity of separated sediments and impurities from the fuel is essential for accurate calculating the remaining fuel quantity on board (ROB). The purpose of this paper is to determine and verify the influence of potential factors that can affect the quantity of fuel consumption and separated sediments quantity from the fuel based on actual data from real product/chemical tanker powered by conventional fuels. By means of statistical analysis the average values, minimums, maximums, standard deviations, and variations, median and modes, standard errors for separated sludge from fuel, heavy fuel consumption (HSHFO) and diesel fuel consumption (LSMGO) during entire observed period and during specific operations modes are obtained. Furthermore, regression formulas between separated sediments from fuel vs fuel consumption during each ship operation mode are generated. Finally, by means of single and multifactorial analysis significant influence of ship operations mode on fuel consumption and separated quantity has been confirmed. This research contributed to find relations more accurately between separated sediments quantity to fuel consumption that might be used for more accurate emission calculation.

Published: June 2023

Most maritime accidents are caused by human error. To reduce these errors, increase safety, protect the marine environment, reduce the administrative burden, and optimize maritime trade, the International Maritime Organization (IMO) decided to implement a concept called e-Navigation. The term e-Navigation refers to the integration of the most modern information and communication systems, both on board and ashore. The research scope of this work is the safety of navigation of the ship during the port entrance. Particularly in this case, the elements that affect the safety of the ship during port entrance are analyzed in a case study of New York port. An adaptive model based on the Bayesian Belief Network (BBN) was created, which evaluates the decision-making elements and risk assessment for port entry. The model is adaptable in the context of the different port requirements. With the presented model, all entities (ships, shipping companies, and service providers) have insight into the estimated decision to enter the port based on the given elements. Further research needs to be continued on the issue of comparing the proposed model with similar models, and how much reliance on the model burdens or facilitates the Master’s decision.

Published: June 2023

This paper presents an analysis and comparison of four steam turbines and their cylinders from four different power plants (marine, conventional, ultra-supercritical and nuclear power plants). The main goal was to find which steam turbine and their cylinders show the best performances, the highest efficiencies, the lowest specific steam consumption and which turbine is the lowest influenced by the ambient temperature change. The highest efficiencies, both isentropic and exergy, are observed in the steam turbine and their cylinders from the ultra-supercritical power plant (whole turbine from ultra-supercritical power plant has an isentropic efficiency equal to 88.36% and exergy efficiency equal to 91.05%). Also, this turbine has the lowest specific steam consumption (7.32 kg/kWh) and exergy parameters of this turbine are the lowest influenced by the ambient temperature change. The worst performance (the lowest efficiencies, high specific steam consumption and the highest sensitivity to the ambient temperature change) show the cylinders and whole turbine from marine propulsion power plant. The same analysis and comparison are also performed for several other steam turbines from four mentioned power plants, so the presented relations and dominant conclusions have general validity. It can be concluded that steam turbines in ultra-supercritical power plants show the best performances in comparison to steam turbines from any other power plant.

Mobilising central bank digital currency to bend the curve of biodiversity loss
Authors: Millard Joe
Published: June 2023

Humanity is at a critical juncture. Despite our efforts to set targets and goals, biodiversity and climate are both changing rapidly, pushing us towards a biosphere our species has not known. To solve this problem one view is that we need transformational change of the economic paradigm, but that might be more an ideal than pragmatic. A new idea could be to take inspiration from recent developments in global carbon market theory and spatial finance, and devise a new central bank digital currency (CBDC) for nature, paid to individuals for reductions in anthropogenic pressure. We could then track a conjunction of anthropogenic pressures from space or remotely, combine that with a model predicting biodiversity change, and then link that to our new global currency that would self-regulate those pressures towards bending the curve. In biodiversity modelling alone there is a lot we would need to learn to make this work, but I think one federated currency for nature might be the economic mechanism we need to fully integrate the pathway of detection, attribution, and action into one global biodiversity observing system (GBiOS), and finally slow biodiversity change.
