Published: March 2023

An anterior open bite may be orthodontically treated by either the intrusion of posterior teeth, the extrusion of anterior teeth, or a combination of both. An improvement in bimaxillary protrusion often involves the extraction of premolars and the retraction of the anterior teeth. The treatment of mesiocclusion mainly involves the mesial and/or distal movement of the molars. However, these three types of malocclusions pose significant treatment challenges when using clear aligners. The present case report describes the treatment of a 24-year-old female patient who presented with the above characteristics, which affected her confidence, willingness to smile and masticatory function. A four-premolar extraction plan was designed to resolve the problems using clear aligners as the patient rejected fixed or visible appliances. After 33 months of orthodontic therapy, except for the counter-clockwise rotation of the mandible and the decrease of facial height, the other objectives established in the pre-treatment plan were achieved, and the patient was satisfied with the results. The combination of clear aligners and premolar extractions effectively corrected the skeletal anterior open bite, bimaxillary dentoalveolar protrusion, and mesiocclusion.
Analysis of Cluster Support Based on the Example of the European Cluster Excellence Initiative
Authors: Młodzianowski Daniel
Published: March 2023

The article is about the issue of cluster development support. For this purpose, the European Cluster Excellence Initiative (ECEI) was analysed. It is the most common measure in Europe to support the development of clusters. It was developed by the European Secretariat for Cluster Analysis. The ECEI inspires national and regional cluster development programmes. As part of the research work, individual in-depth interviews were conducted with representatives of Polish clusters and a survey was conducted with representatives of European clusters. On their basis, it was established that the activities offered under the ECEI meet the expectations placed on it by the creators. However, this does not mean that it is a perfect system. A number of areas were identified that require changes. Some suggestions are simple to implement, while others are more complicated. These recommendations require changes that the European Secretariat for Cluster Analysis should review and decide on them.
MRI Appearance of a Giant Ovarian Sero-mucinous Cystadenofibroma Mimicking Ascites. A Case Report and Brief Literature Review
Authors: Fülöp Andrei Cristian , Opriș Zeno , Fülöp Eugen Francisc , Ghilință Ioana Geanina , Baróti Beáta
Published: March 2023

Introduction: Giant ovarian cystadenofibromas are rare, mostly benign tumors. In the early stages, they are asymptomatic; however, as they grow in size, they begin to produce symptoms, most often due to the compressive effects they exert on surrounding structures. In the early stages, they are frequently diagnosed by ultrasonography, but complicated cases or cystadenofibromas that reach giant dimensions are ideally evaluated by magnetic resonance imaging (MRI) to establish a therapeutic surgical decision that is as safe as possible for the patient.

Case report: We present the case of a 49-year-old perimenopausal patient without vaginal bleeding or other gynecological symptoms who presented to the hospital with abdominal pain and abdominal distension with increasing intensity. Ultrasound examination revealed the presence of a high volume of fluid in the abdomen, and MRI and histopathological examination confirmed the diagnosis of a giant left ovarian type III seromucinous cystadenofibroma. The patient was treated surgically, with favorable postoperative evolution.

Conclusion: Giant cystadenofibromas are rare clinical entities that must always be considered in the differential diagnosis of an abdominopelvic pathology in middle-aged female patients and should ideally be investigated by MRI to accurately define their origin, characteristics, and local invasion.

Published: March 2023

Introduction: To develop an in-house acrylic-based step-wedge phantom with several thickness configurations for calibrating computed tomography (CT) localizer radiographs in order to measure the water-equivalent diameter (Dw) and the size-specific dose estimate (SSDE).

Method: We developed an in-house step-wedge phantom using 3 mm thick acrylic, filled with water. The phantom had five steps with thicknesses of 6, 12, 18, 24, and 30 cm. The phantom was scanned using a 64-slice Siemens Definition AS CT scanner with tube currents of 50, 100, 150, 200, and 250 mA. The relationship between pixel value (PV) and water-equivalent thickness (tw) was obtained for the different step thicknesses. This was used to calibrate the CT localizer radiographs in order to measure Dw and SSDE. The results of Dw and SSDE from the radiographs were compared with those calculated from axial CT images.

Results: The relationship between PV and tw from CT localizer radiographs of the phantom step-wedge produced a linear relationship with R2 > 0.990. The linear relationships of the Dw and SSDE values obtained from CT localizer radiographs and axial CT images had R2 values > 0.94 with a statistical test of p-value > 0.05. The Dw difference between those from CT localizer radiographs and axial CT images was 3.7% and the SSDE difference between both was 4.3%.

Conclusion: We have successfully developed a step-wedge phantom to calibrate the relationship between PV and tw. Our phantom can be easily used to calibrate CT localizer radiographs in order to measure Dw and SSDE.

According to previous research, there are several leadership styles that influence corporate management. As a consequence of strong leadership, an organization's human capital grows. Through the concept of charismatic leadership and what it affords us in terms of productivity, a particular component will be examined. Leadership is an engagement between a leader and followers in which all facets of the partnership are important, especially how they interact. Leaders will be considered charismatic as long as followers continue to put their trust in them and as long as the results of their efforts are acknowledged. This research focuses on the complex interaction of factors that enable the success of charismatic leadership and implies the need of technical supervision for best results.

In the past few years, organizations have become more likely to digitize their human resources because it adds value and makes things run more smoothly. At the same time, digitization cut work hours and made it easier to do repetitive tasks without making mistakes. Digitizing human resources in public organizations can be very helpful and important. This is because, as a result, there won't be any more bottlenecks or times when there are more requests than staff. There also won't be any longer lines at the counter. The purpose of our research is to analyze organizations through the prism of the current needs generated by the health crisis (the COVID-19 pandemic) and to present the principles of organizational resilience, as found in the specialized literature. The most common approach to research is an examination of specialized literature from the point of view of economic and social theories that take organizational resilience into consideration. The following findings focused on separating common characteristics and identifying the underlying principles of resilience in different organizational environments.

Published: March 2023

The optical energy gap of anthocyanin compounds from sea lettuce extract (Ulva lactuca L.) has been calculated using the Tauc plot method. Sea lettuce plants taken at Sanur Beach Bali. The sea lettuce was dried then mashed and extracted for 24 hours, the last being macerated through three cycles. The extraction results are then evaporated to obtain a thick extract solution. Extracted and evaporated-extraction samples were characterized by UV-Vis in the wavelength range of 200-800 nm. From the characterization results, it was found that the absorption of anthocyanin compounds for the extracted samples was at a wavelength of 268 and 412 nm. Meanwhile, for the extraction-evaporation sample, the absorption is at a wavelength of 286.5 and 408 nm. By using the Tauc plot method, the optical energy gap values ??for the extracted and extraction-evaporated samples were 2.69 and 2.54 eV, respectively. Therefore, anthocyanin compounds from both extracted and evaporation-extracted samples qualify as dye sensitized solar cells (DSSC) for TiO2 semiconductors.

Published: March 2023

This study aims to reveal how the Madura indigenous communities' local wisdom is in the process of participatory planning and budgeting and determines the model of local community wisdom in the process of participatory planning and budgeting as a whole. This study uses a qualitative ethnomethodological approach with a constructivist paradigm. The study results show that formal deliberations, namely development planning deliberations in general, are almost the same as in other regions in Indonesia. However, in the Madurese indigenous people, there are differences from most other regions in Indonesia, namely that apart from carrying out development planning deliberations, they actually carry out informal deliberations, namely community meetings. Moreover, the implementation of participatory budgeting, which is proven elsewhere, is not proven in the Madurese indigenous people who use community consultations as an initial stage in formulating community needs by providing aspirations in order to achieve local goals.

Published: March 2023

In recent years, intensive legal regulations aimed at the production of urban areas in Türkiye, the phenomenon of migration, the spread of higher education, abnormal cost increases in agricultural activities have accelerated urbanization. Parallel to the increase in the urban population, the food supply remains insufficient. The inability to increase the production of food products brings with it problems such as malnutrition, inflation, foreign trade deficit, food security. The natural areas harbored by rural and urban areas are shrinking and being destroyed by the pressure of rapid urbanization. In addition to the abandonment of rural areas, the food crisis that has arisen as a result of the intervention of the urbanization process in agricultural areas has increased the responsibility of the central government and municipalities. In order to meet the food needs of the population and implement sustainable agricultural policies, municipalities are taking different and innovative approaches. Municipalities are making direct and indirect attempts to provide people with cheap and reliable food. In this study, the activities carried out by the municipalities in Türkiye to support sustainable agriculture and their economic and social effects were examined.
The Right of Access to Public Information: Human Rights Issues, Transparency and Good Governance
Authors: Liambomba Didier Yangonzela
Published: March 2023

The right of access to information is based on both Article 19 of the Universal Declaration of Human Rights (UDHR) and the International Covenant on Civil and Political Rights (ICCPR), which guarantee everyone the right and freedom “to seek, receive and impart information and ideas” by any means of their choice. Article 24 of the Constitution of the Democratic Republic of Congo (DRC) guarantees the right to information in the following terms: “everyone has the right to information”. The effective manifestation of this right to information remains closely linked to the exercise of freedom of expression and opinion on any subject of public interest and its inevitable corollary, freedom of information. The effectiveness of the right to information also depends on citizens' participation in the nation's public life. A population well-informed by its government can fight against fake news and the spread of false rumors while promoting the fight against corruption and good governance. Accessing public information is one of the most important conditions for assessing the democratic management and openness of society to citizen participation. As an inalienable right, access to information is the foundation of a free, democratic and transparent society. The research was based on the legal approach and the comparative method. The former allowed the subject to be approached by grasping the quintessence of the various existing legal standards. The latter helped to compare the various internal and extra-internal legal instruments based on comparative law, particularly French law. This analysis also used the documentary technique and the free interview in the form of a chat with ordinary citizens or any other personality (civil society groups, journalists, entrepreneurs, national and local elected representatives, other professional, political and trade union groups, and civil servants).

Published: March 2023

An integrated approach embracing field studies, petrographic and geochemical investigations together with zircon U-Pb-Hf data was used to investigate the petrogenesis of potassic granite suites along the southern margin of the Zimbabwe Craton. Zircon U-Pb geochronology identifies age relationships, revealing coeval magmatism of the ca. 2 635 ± 5 to 2 625 ± 3 Ma Chilimanzi Suite, and the ca. 2 627 ± 7 Ma Razi Suite. Both suites represent syn- to late-tectonic, high-K, calc-alkaline, and metaluminous to weakly peraluminous granites and granodiorites with I-type affinity. The granite suites contain xenocrystic zircons, with the Chikwanda Pluton of the Chilimanzi Suite yielding a grain of up to 3 206 Ma old. Both granite suites exhibit eHf values of between -5.6 ± 1.3 and -7.3 ± 1.6 and TDM model ages of ca. 3.4 to 3.5 Ga which suggests a similar crustal source. The unradiogenic zircon Hf isotopic compositions are consistent with formation of the granite suites through partial melting of pre-existing crustal protoliths, including Palaeoarchaean tonalite-trondhjemite-granodiorites (TTGs) of the Zimbabwe proto-craton. Partial melting of lower crust gave rise to granitic melts that became emplaced over a relatively short time interval from 2 635 to 2 625 Ma and heralded the stabilisation of the Zimbabwe Craton.

In addition to virtually identical ages, the Razi and Chilimanzi suites have similar geochemistry. Small geochemical differences between the Chilimanzi and the Razi suites are attributed to the crustal level at which they are preserved, the modal mineralogy and the extent to which the melts are evolved. The Razi Suite melts were generated from lower crust partial melting of thickened charnockite-enderbite source rocks rich in heat producing elements. The partial melting occurred under fluid-absent conditions and magmas were emplaced at lower to mid crustal levels. The Chilimanzi Suite magmas were similarly derived by the partial melting of TTG lower crust and were emplaced at upper crustal levels. Accordingly, the Chilimanzi Suite exhibits more evolved magmatic fractionation indices indicated by high Rb/Sr, as well as low K/Rb ratios relative to the Razi Suite. Both suites reveal varying degrees of enrichment in incompatible elements including Rb, Th, and U, as well simultaneous depletions in Ba, Sr, and Hf which underscores the role of fractional crystallisation in the evolution of the granitic magmas.

Published: March 2023

Current trends in the aerospace industry for the digitization of data, tools, and services call for novel solutions that can keep track of the latest technological advancements. Moreover, the increasing drive toward model-based approaches imposes the use of models for the development of complex systems, such as satellites. New types of methods and tools are needed in order to manage the still-growing complexity of embedded systems and their corresponding models. This paper addresses issues related to space systems (in-service) operations and proposes a multimodel approach to address them. The multimodel approach aims at facilitating the task of operational diagnosis by creating a monitoring and diagnosis-dedicated system model derived from existing system design (architecture, functional behavior, and safety) models. The purpose of the diagnosis-dedicated model is to enable the codesign of the system and its diagnosis tools in order to improve the performance of diagnosis activities and the system’s availability. This paper demonstrates the interests of the suggested approach with regard to the limitations of current practices.

A wide variety of models and methods for the prediction of the surface pressure spectrum beneath turbulent boundary layers is presented and assessed. A thorough review is made of the current state of the art in empirical and analytical pressure spectrum models; and predictions of zero, adverse, favorable, and nonequilibrium pressure gradient boundary layers are examined using a steady Reynolds-averaged Navier–Stokes (RANS) prediction of a subset of a pressure gradient boundary-layer benchmark flow case. The existing empirical models show either an inability to adapt to pressure gradient conditions or an oversensitivity to model inputs, producing nonphysical results under certain flow conditions. New empirical models are created using a gene expression programming machine-learning algorithm based on both experimental and RANS inputs. The various input options for analytical Toegepast Natuurwetenschappelijk Onderzoek (TNO) modeling are presented and assessed, and recommendations for best practices are made. The developed models show improvement in both accuracy and robustness over existing models.
Confined Boundary-Layer Flashback Flame Dynamics in a Turbulent Swirling Flow
Authors: Novoselov Alex G. , Ebi Dominik , Noiray Nicolas
Published: March 2023

Understanding boundary-layer flashback is critical to the design of safe and efficient gas turbines, especially as the addition of highly reactive hydrogen to these devices becomes a prevailing trend for reduction of carbon dioxide emissions. In this work, the boundary-layer flashback of lean hydrogen–air mixtures is studied using large-eddy simulations based on a generic turbulent swirl burner previously investigated experimentally. Simulations at increasing equivalence ratios are used to identify the flashback limits, showing reasonable qualitative agreement with experimental measurements. Flame dynamics during flashback are compared to previous experimental studies, indicating that important physics are captured in the simulations even if the exact flashback limits are not. In particular, a change in the swirl vane angle is shown to dramatically change the flame dynamics, with flame propagation occurring in the direction of swirl at high angles and against the direction of swirl at low angles, consistent with experimental observations. The near-wall nonreacting mean velocity field is shown to be controlled by a temporally stationary flow instability, which is directly responsible for the counterswirl flame flashback exhibited at low swirl angles. Finally, the interaction of local axial flow velocity and flame propagation speed of the leading flame point is investigated with varying swirl angles both before and after the onset of flashback, elucidating the differences in flame dynamics in all four of these cases. In particular, the importance of local flame extinction on flashback limits is emphasized.

In the work, a comparative analysis of the main technological parameters, as well as the stability of the injection molding process of the primary glass-filled (30%) polyamide 6 and the secondary composition of the mixture of glass-filled polyamide 6/polycarbonate was carried out.Non-standard multi-component car parts obtained on the hybrid casting machine "ENGEL" were used as the starting ma-terial. The black element of the part is cast from glass-filled polyamide (PA6GF30), the white element -from polycarbonate (PC). Grinding of parts was carried out by a mechanical method on a "Rapid 200" shredder. After mechanical processing, a mixture ofparticles was obtained from unseparated PA6GF30/RS components in the ratio of 90/10 wt.%. The granulate was used to cast the black component of the part without adding the original polymer composition on the "ENGEL" casting machine. Statistical data for determining the stability of the process and the machine were obtained using the Q Table software module. The results of the research were processed by the 6SIGMA method to obtain the appropriate indicators of process stability.It is shown that the use of the secondary mixture requiresan increase in the drying time and temperature, the parameter of the melt cushion in comparison with the primary material. At the same time, other parameters of the process did not undergo significant changes. At the same time, the stability of the casting process when using the secondary composition did not undergo statistically significant changes compared to the primary material and is within the permissible limits. The obtained resultsprove the possibility of reprocessing multicomponent waste polymer compositions by injection molding. This can reduce the cost of production by reducing the cost of raw materials, reduce the share of unprocessed polymer waste, and have a positive impact on the ecological aspects of the environment.

Most construction projects carry a certain level of risk, and in order to determine and manage them, it is necessary to know their essence, causes, carefully plan the construction process and ensure the ability to quickly make the right decisions at each stage of the construction process [1]. Therefore, determining the essence of risks, their causes and effective methods of their management is extremely important to ensure the successful implementation of construction projects [3;4;5].During the construction process, several types of risk factors may arise simultaneously, in particular, an unexpected increase in the cost of construction materials, completed works, delays in meeting the deadlines of construction projects caused by the investor, contractor, environment, etc. As shown by the feedback of investors and contractors,the impact of COVID-19 on construction projects is significant, in particular, quarantine restrictions led to delays in the completion of projects and an increase in the cost of their completion.Analyzing the research data, it can be noted that construction projects regularly suffer from significant incidents, which are related to both the financial component and a large number of emergency situations. Effective construction risk management requires persistent attention to detail and training of the workforce to avoid undesirable situations during construction, including quality construction, accident prevention. International risk management standards vary widely, and there is almost always room for improvement. Infrastructure projects are becoming more and more complex and require more complex methods of control over them. When design work does not meet construction standards, the cost of repairs and associated risks can be extremely high. Therefore, insurers, contractors and clients should be interested in minimizing losses and perceive risk engineering as a way of positive contribution to the process of achieving a better result and as a result of a worthy investment in the future project.According to the PMBoK international standard, the risks of construction projects, their causes and solutions must be recorded, that is, timely response to negative risks contributes to the smooth execution of construction works without financial losses.

В докладе обсуждается возможная реализация распределенных систем управления средствами процесс-ориентированного программирования. Предлагаемый подход характеризуется, с одной стороны, топологически-независимой спецификацией алгоритма управления и, с другой стороны, возможностью использования существующих методов формальной верификации за счет сохранения семантики централизованной процесс-ориентированной программы.

The report discusses the possible implementation of distributed control systems by means of process-oriented programming. The proposed approach provides, on the one hand, a topologically independent specification of the control algorithm and, on the other hand, using existing formal verification methods by preserving the semantics of a centralized process-oriented program described by hyperprocess model.
