Beyond Borders: Exploring Existence Theorems in Free Boundary Population Models
Authors: Oluwasegun Kayode , Ambrose David , Wright Douglas
Published: April 2024

With the introduction of mathematics into biological research, patterns arising from biological problems can be effectively studied. The complex interactions involving biological systems and invading pathogens can be described using mathematical frameworks of partial differential equations (PDEs). More specifically, the spread of new or invasive species can be set up as a population model with a freely moving boundary. Proving the existence of solutions to this model helps us scientists to have a solid understanding of how the population works and predict how it changes in the future. Generally speaking, the mathematical modeling of ecological problems is difficult. In this work, we propose a different approach to the understanding of the spreading of species. We have introduced a special case of the well-known Stefan condition as the equation governing the free boundary. Our study therefore seeks to develop rigorous mathematical frameworks underpinning existence theorems and see the role of free boundaries in shaping the behavior of populations. We have employed energy methods with the goal of building a general framework that will be highly portable for use in other, related problems in the modeling of infectious diseases. Invading fungal pathogens like Candida albicans cause over 150 million mucosal infections and nearly 200,000 deaths per year due to invasive and disseminated disease in susceptible populations. This work represents significant advancements in resolving a long-standing mathematical problem and addressing one of the most important health-related issues nations are grappling with.
Reasoning in Euclidean Geometry using Information

Invariance Principle
Authors: Amiri Manouchehr
Published: April 2024

This article presents an introduction to a new logical reasoning method for Euclidean geometry basedon the invariance principle of information (data). Due to this principle, any geometrical configuration(shape or entity) in Euclidean geometry possesses a conserved content of geometrical data that could beexpressed as information bits. On the basis of this principle, we explain what is the content of informationbits and how is the analysis of this content in Euclidean geometry. Every geometric structure is actually aset of information bits that define that structure. We discuss the relationship between bits of informationwith the use of straight edge and compass in Euclidean geometry and show that theorems of Euclideangeometry can be expressed in the term of bits of information. In this regard, we show that the abilityto draw a geometric structure, as well as theorems and propositions related to these structures, can bereduced to the rules of the invariance of information bits, and consequently leads to a new reasoningmethod in Euclidean geometry that can be applied for reasoning algorithms in AI. Based on this principlethe converse of corresponding angles postulate and some of the theorems of constructible numbers andregular polygons are proved with concise proofs.
Transcriptome analysis reveals the mechanism of NaHCO3 promoting tobacco leaf maturation
Authors: Wang Tingting , Zhao Yuanyuan , Wang Dexun , Shi Hongzhi
Published: April 2024

NaHCO3 accelerates the aging of tobacco leaves; however, the underlying molecular mechanisms have not been elucidated. This study aimed to explore the mechanism of NaHCO3 in the promotion of tobacco leaf maturation using transcriptome analysis. Leaves on plants or detached leaves of the tobacco variety, Honghua Dajinyuan, were sprayed with or without 1% NaHCO3. The leaf yellowing was observed, the pigment content and enzyme activities were determined and RNA sequencing (RNA-seq) was performed. Spraying NaHCO3 onto detached leaves was found to promote leaf yellowing. Pigment content, catalase activity, and superoxide dismutase activity significantly decreased, whereas peroxidase activity and malondialdehyde content significantly increased. RNA-seq demonstrated that spraying with NaHCO3 upregulated genes associated with cysteine and methionine metabolism; alpha-linolenic acid metabolism; and phenylalanine, tyrosine, and tryptophan biosynthesis and downregulated genes related to photosynthesis and carotenoid biosynthesis. Genes correlated with autophagy-other, valine, leucine, and isoleucine degradation, and the MAPK signaling pathway were upregulated while those correlated with DNA replication, phenylalanine, and tyrosine and tryptophan biosynthesis were downregulated in detached leaves sprayed with NaHCO3 compared with the plant leaves sprayed with NaHCO3. Overall, this study is the first to elucidate the molecular and metabolic mechanisms of NaHCO3 in the promotion of tobacco leaf maturation.
Why together? Archaeology and zoology about medieval leather products on the example of Szczecin
Authors: Bogumiła Kowalska Anna
Published: April 2024

Many years of archaeological excavation brought to light a rich material, that can be used in research of topics important from a social and economic point of view, such as the character of the production and/or organization, the development of technique and production technology, or the assortment of goods. A deep analysis of the selected categories of artifacts, in this case made of leather, can be used for a double purpose – a reconstruction of the process and conditions of early medieval leather craft formation, as well as a presentation of their role and significance in the activity structure of the inhabitants of Szczecin. Such an attempt to grasp the rules governing the development of one of the most important production branches – leatherworking, has been undertaken on the basis of leather objects that can be found on a mass scale in Szczecin’s cultural layers dated for the period from the early 10th to the mid-13th century. Key to these studies are the results of zoological analyses, which perfectly complement the archaeological conclusions.
How word stress is realized in Thai: evidence from the ordering of coordinate compounds
Authors: Sirintranon Noppakao , Hsieh Feng-fan
Published: April 2024

This study challenges the widespread belief that Thai lacks word stress, demonstrating its pivotal role in morphophonology. Through a Maximum Entropy analysis, we investigated how specific segmental properties statistically influence speakers’ choices of word order in coordinate compounds. Results indicate a significant effect of phonological weight on the ordering patterns. Specifically, the dispreference for stop codas in final positions and the preference for long or low vowels word-finally converge to differentially distribute phonological weight, ensuring that final syllables are heavier in accordance with the Stress-to-Weight Principle. Additionally, a marginal affinity is observed between the final syllable and the (historical) high-register tone, aligning with the well-documented tone-stress interaction where high tones gravitate towards stressed syllables. These findings provide compelling evidence for the existence of word stress in Thai: compound stress necessarily coincides with word stress, as dictated by the Continuous Column Constraint. Thus, this work suggests that relying solely on phonetic cues is insufficient for identifying stress; instead, a comprehensive analysis incorporating “phonological exponents” is essential to capture the greater phonological contrasts licensed in stressed syllables. This study also contributes to a deeper understanding of metrical and prosodic prominence, revealing that word stress can sometimes be masked by higher-level prominence.
Chinese topic constructions are derived by movement: evidence from acceptability judgment experiments
Authors: Tian Qilin , Park Myung-Kwan , Cheng Gong , Wang Jiaming
Published: April 2024

Chinese, a topic-prominent language, abounds with gapped and gapless topic constructions. Several explanations of how topics are derived have been proposed, which fall into three categories: the base-generation approach, the mixed approach and the movement approach. In this study, we conducted two experiments to examine the island sensitivity of topic constructions in Chinese, bringing novel evidence to adjudicate the different approaches to topicalization in this language. The results indicate that island effects can be detected in both gapped and gapless topic constructions, which supports the movement approach to topic constructions in Chinese, making influential hypotheses such as the topic licensing condition and the topic interpretation condition dubious. Our findings also provide new evidence for the influential proposal that Merge is applied freely (Chomsky, Noam. 2001. Derivation by phase.

Digitale Öffentlichkeit(en). Linguistische Perspektiven
Authors: Merten Marie-Luis , Knuchel Daniel
Published: April 2024

In this thematic volume we ask how digitalization and mediatization are transforming public communication and its conceptual understanding. This introductory text delves into the historical shift from oral and body media to written media in societal communication, highlighting the evolution through telecommunication mass media to the replacement of analog communication by digital forms. It addresses the lack of consensus on the definition of ‘publics’ and public communication, underscoring the multidimensional, heterogeneous, and fluid nature of these concepts.

We ask how digitalization and mediatization processes raise questions about fundamental changes in publics due to new technological-communicative possibilities. Furthermore, we discuss the concept of publics as communicatively constructed and maintained, shaped by media and community ideologies.

We propose a continuum model for digital/digitized publics, ranging from dyadic communication to multi-party communication. It emphasizes four key aspects for linguistic engagement with digital publics: communicative construction, technical and social affordances, multiplicity of addressing, and practices of digital community formation. With this model and the contributions following the introduction we contribute to a nuanced understanding of digital publics, considering their scale, complexity, and the dynamics of content creation and audience interaction.
Digitale Öffentlichkeit(en) metapragmatisch. Zur Aushandlung und Überschreitung kommunikativer Grenzen am Beispiel des Bodyshamings auf YouTube
Authors: Merten Marie-Luis
Published: April 2024

This paper explores the multidimensional phenomenon of digital publics from a metapragmatic perspective. The focus is on a (potentially) digital-public YouTube discourse fragment on the topic of bodyshaming (on the Internet). In particular, negotiation and violation practices of communicative boundaries (in social media) are thematized. The underlying corpus is composed of (1) a YouTube video of a female (high reach) social media actor who, among other things, recontextualizes (hurtful) comments about her weight gain as well as about a possible pregnancy, and (2) follow-up communication to this video. In the qualitative-quantitative study, special attention is paid to the following questions: (1) Which concept of digital public spheres do the users emphasize in the discussion and (2) which understanding of communicative boundaries (in a digitalized lifeworld) do these participants communicate? A media-critical community is illuminated that construes solidarity with the initial contributor and negotiates the boundaries of appropriate Internet communication.
„Ich freu mich ja SO übelst“ – Praktiken explizit performativer Beziehungsgestaltung in Fancalls
Authors: Hauser Stefan
Published: April 2024

Fancalls are telephone conversations filmed and posted on YouTube that influencers hold with selected fans. It is a type of conversation that utilises the affordances of the digital public sphere and enables a specific form of relationship building between influencers and fans. The following considerations are based on the assumption that the public sphere is always part of social practices. This suggests an interactionist understanding of the public sphere for the following observations and their categorisation. A number of communicative patterns can be observed in fan calls, which will be discussed in this contribution with regard to their specificity for digital-public communication. The extent to which the specific interaction constellation and the genre-related characteristics of this type of conversation are an expression of a (changing) digital public sphere will be discussed in this article.
Effect of Preheating on Microhardness, Degree of Conversion, and Depth of Cure of Various Bulk-Fill Composites
Authors: Keleş Zeynep Hale , Tarım Berna
Published: April 2024

Background: This study aims to evaluate the effect of preheating on microhardness, degree of conversion, and depth of cure of bulk-fill composites (Tetric EvoCeram Bulk-Fill, SonicFill2) and a conventional composite (Tetric EvoCeram).
Methods: Layers of Tetric EvoCeram (2 mm), Tetric EvoCeram Bulk-Fill (4 mm), and SonicFill2 (5 mm) were placed in 4-mm diameter molds and polymerized at room temperature or heated to 55oC for 10 s with a total number of 60 samples. Then, the top surfaces of samples were polished. 30 samples’ Vickers microhardness was measured from the top and bottom surfaces. The other 30 samples were pulverized into a fine powder, and the composites’ degree of conversion was measured with attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy. Obtained data were analyzed statistically with a significance level of p<0.05.
Results: The degree of conversion of Tetric EvoCeram was higher than the minimum rate of clinically acceptable value, which is 55%, but the scores of Tetric EvoCeram Bulk-Fill and SonicFill2 were below the threshold. Preheating increased the degree of conversion of Tetric EvoCeram Bulk-Fill and SonicFill2. In addition, preheating did not affect depth of cure of SonicFill2 but decreased the rate of Tetric EvoCeram Bulk-Fill.
Conclusion: The results showed that the effect of preheating on the degree of conversion and depth of cure varied according to the material.
Keywords: Preheating, bulk-fill composite, degree of conversion, depth of cure, microhardness.
Restorations of Endodontically Treated Teeth
Authors: Ak Şevval Sena , Cimilli Hale
Published: April 2024

Endodontically treated teeth are fragile compared to vital teeth. The reason for the decrease in fracture resistance and hardness is related to the deterioration of the structural integrity as a result of caries, trauma and cavity preparation. Restorations in endodontically treated teeth are applied considering the remaining tooth structure and functional status. For many years, post core systems that require additional preparation in the root canal, as well as the loss of most of the coronal tooth structures, are used for the final restoration of endodontically treated teeth. Endocrowns are monoblock restorations that attach to the pulp chamber and its walls, providing macro-mechanical and cementation with micro-mechanics, thus requiring no additional preparation. The first study written on ceramic endocrown was published in 1995. In this study, it is defined as a ceramic monoblock production technique for the restoration of endodontically treated teeth. This procedure was later named "endocrown" in 1999.

Asimetrinė komunikacija: kaip kalbame su gyvūnais ir apie juos?
Authors: Kamandulytė-Merfeldienė Laura , Dabašinskienė Ineta
Published: April 2024

The emotional bond between pets and their owners is intimate in many cultures, where pets are often regarded as family members or even children. Communication with pet animals is frequently likened to infant/child-centered speech situations (Mattiello et al. 2021: 150). Pet owners commonly employ specific language forms that convey sympathy, empathy, or playfulness. This study aimed to explore the characteristics of pet-directed speech in Lithuanian, utilizing a questionnaire survey conducted through the Google Forms platform.Survey data reveal that women, predominant in this study, often perceive pets, particularly dogs and cats, as family members, bestowing upon them the status of children. This is evidenced by the frequent use of diminutives and onomatopoeia. The profusion of adjectives employed to depict pets supports the assertion that such communication is influenced by anthropomorphism, attributing human-like characteristics to pets. The regular use of diminutives when addressing pets or describing their belongings, such as food and toys, indicates that diminutives serve a pragmatic function. They make the speech act more playful, enabling owners to accomplish their goals in a less formal, friendlier manner, even when discussing less pleasant topics.
Features injuries handball players 18-20 years old in competition
Authors: Marina Gillard , Fateh Zereg
Published: April 2024

Handball is a game sport that combines a high level of physical psychological preparedness and technical and tactical skill. The first great successes come to players after 1-12 years of systematic preparation. The most talented young handball players from youth begin to move to the teams of men's clubs, and then join the ranks of the national team, while others, having received injuries, say goodbye to handball. The purpose of the study is to determine the nature of injuries to handball players aged 18-20 years, to identify the main types of injuries to handball players of different ages and playing positions. The data obtained suggest insufficient physical and technical-tactical readiness of handball players under 20 years old for the intense conditions of major international competitions. In turn, this makes it possible to develop effective means of preventing injuries in the early stages of long-term training.
Stealth adapted viruses and the epidemic of chronic illnesses
Authors: Martin W John
Published: April 2024

Stealth adapted viruses elude recognition by the cellular immune system due to the loss or mutation of genes coding the relatively few components typically targeted by the cellular immune system. Political barriers to accepting the existence of these viruses arose when it became apparent that some of the viruses had originated from the cytomegaloviruses that commonly infected monkeys used to produce poliovirus vaccines. Many virologists are seemingly unaware of the restricted targeting of viral components by the cellular immune system or that genetically defective viruses can continue to replicate and cause cellular damage. Immunologists may also be somewhat reluctant to acknowledge possible non-immunological virus defense mechanisms. There are growing concerns regarding the increasing incidence of major chronic illnesses. Patient support groups are continually advocating for more research on the cause of specific disease entities. There is also a growing sense that special interests may have unintentionally imposed toxic exposures on the public leading to chronic illnesses. Relief from such exposures is being demanded by various Health Freedom movements. This article is intended to better inform the Health Freedom movements and various chronic illness support groups about the existence of stealth adapted viruses. A broader understanding of these viruses and their incorporated renegade cellular and microbial sequences will facilitate therapeutic endeavors, especially those based on the Alternative Cellular Energy (ACE) pathway.
Evaluación Docente E Incentivos
Authors: Wenzell Ojeda Peter A.
Published: April 2024

La administración de organizaciones educacionales ha implementado sistemas de compensación e incentivos que reflejan, de gran manera, su filosofía de competencia y su visión individualista del mundo. Los profesores han visto que sus objetivos de ser respetados y tratados como profesionales no han sido reconocidos ni respetados. Estas orientaciones individuales y competitivas pueden ser analizadas tanto de una forma relacionada con las orientaciones grupales y comunitarias como también cooperativas e interdependientes. Los efectos cuantitativos y cualitativos de estos sistemas de compensación pueden ser comparados. Los sistemas competitivos han destruido muchos de los cimientos básicos de las sociedades humanas: relaciones comunitarias, valóricas y cooperativas, como también aquellas intra e interfamiliares. Este ensayo pretende demostrar por qué han fracasado y proponer un sistema alternativo.
On linear spaces of bipartite graphs
Authors: Alekseev Vladimir E. , Zakharova Darya V.
Published: April 2024

The article considers symmetric linear spaces of bipartite graphs (SLSBG), i.e. the set of bipartite graphs with fixed lobes closed with respect to the symmetric difference and permutations of vertices in each lobe. The operation of symmetric difference itself is introduced in this work. The paper provides a structural description of all SLSBG. Symmetric linear spaces of bipartite graphs are divided into trivial (four SLSBG) and nontrivial. Non-trivial ones, in turn, are divided into two families. The first is C
-series consisting only of bicomplete graphs, i.e. graphs that are a disjunct union of two complete bipartite graphs graph wings). The second family is D
-series that includes graphs in which the degrees of vertices in one lobe have the same parity, and in the other lobe these degrees may be arbitrary. It is proved that every SLSBG of the D
-series coincides with one of nine sets defined by the parity of the vertices’ degrees. For the SLSBG of the C
-series it is obtained that every two-sided SLSBG (i.e., containing graphs whose both wings have nonempty lobes) is the intersection of the set of all bicomplete graphs with the set of all graphs with an even number of edges or with any space of the D
-series.
On the motion stabilization of a three-link robotic manipulator with incomplete measurement
Authors: Kolegova Lubov V.
Published: April 2024

Abstract. This paper considers a mathematical model of a manipulator which consists of a vertical column, two links, connected to it in series, and a gripper with a load. The column resting on a fixed base can rotate around its vertical axis. The links are connected by cylindrical hinges allowing them to rotate in the same vertical plane. The column and the links are modeled as rigid bodies with the links having unequal principal moments of inertia. The position of the manipulator in space is determined by three rotation angles of the column and the links. The manipulator can have several types of steady-state program movements. When gravitational torques are compensated by control torques applied in the cylindrical hinges, the manipulator has a program equilibrium position. The manipulator can also have a program motion when the column rotates at a given constant angular velocity, and the links have given relative equilibrium positions in their plane. The stabilization problem of manipulator motion is investigated by means of control torques with feedback when only the rotation angles of the column and links are measured. The problem posed is solved in the form of a nonlinear proportional-integral controller taking into account the cylindrical phase space of the manipulator's mathematical model. The solution includes construction of a Lyapunov functional with a semi-definite derivative and application of the corresponding theorems on the asymptotic stability of non-autonomous functional differential retarded-type equations. The obtained conditions for the program motion stabilization are robust with respect to the mass-inertial parameters of the manipulator. The numerical simulation results demonstrate global attraction to its given position in cylindrical phase space.
EXAMINING CITIZEN AWARENESS OF DECENTRALIZATION AND LOCAL FINANCES THROUGH SURVEY METHODOLOGY
Authors: Tsachev Zh.
Published: April 2024

The issue of decentralization is currently of great importance in Bulgaria. It is related to a number of reforms in local self-government, which require broad public consent. This consent should be derived or obtained after conducting a large-scale information campaign to acquaint the Bulgarian public with the administrative, political and financial framework of the local government. The purpose of this paper is to investigate the awareness of the local community on some key topics in the area of municipal revenue. The main method used is the survey method. The obtained results show that the local community has not reached this level of awareness, which would provide a solid basis for civil participation in the local self-government reform process. The conclusion to be drawn is that the state authority must conduct large-scale information campaigns and organize discussions on the issues of decentralization.
BUILDING COOPERATIVE BUSINESS MODELS IN AGRICULTURE
Authors: Turlakova T.
Published: April 2024

Cooperative models are a specific form of successful business. In their activity, they refer to specific principles and values, and due to their democratic structure, they contribute to socio-economic development, provide employment, help to satisfy the needs of their members and clients. Due to their unique business model, cooperatives manage to adapt and respond more effectively to economic, market and financial challenges. The numerous advantages of the cooperative business model are a prerequisite for its transformation into a condition for sustainable regional development. On the other hand, the lack of detailed information on cooperatives limits the possibility of a detailed assessment regarding the size and influence of these structures. The purpose of this report is to reveal the prerequisites for building cooperative business models in agriculture, to indicate their main characteristics and condition, as well as to outline the main prospects for their development.

Published: April 2024

Although mobile phones as a rapid communication vehicle can lead to improved quality of healthcare, they can also facilitate the transmission of pathogens to patients. This current research focuses on genetic diversity, and genes involved in resistance and biofilm production of Staphylococcus aureus isolates from mobile phones of medical students. Antibiotic resistance profiling and polymerase chain reaction (PCR) amplification of antibiotic resistance and biofilm-related genes were investigated and statistically analyzed. Staphylococcal cassette chromosome mec (SCCmec) types were analyzed by multiplex PCR, and S. aureus protein A gene typing (spa typing) was done using PCR and sequencing. Sixty-four S. aureus isolates (16.8%) were obtained from 380 medical students' mobile phones who were working in hospitals. The findings showed that 71.9% of the isolates were MRSA and 78.1% were classified as MDR. All isolates exhibited sensitivity to vancomycin and linezolid. Overall, 7.8% of the isolates displayed an inducible clindamycin resistance phenotype, while 26.7% showed resistance to mupirocin. The results indicated that 68.8% of the isolates were biofilm producers, with 7 isolates (15.9%) classified as strong producers, 22 isolates (50%) as moderate producers, and 15 isolates (34.1%) as weak producers. The most prevalent type was CC8-MRSA III/t030 (18.7%), followed by CC8-MRSA III/t037 (12.5%), CC/ST22-MSSA/t790 (10.9%), CC1-MRSA IV-t114 (9.4%), CC1-MRSA IV-t127 (7.8%), CC8-MRSA V/t064 (7.8%), CC/ST15-MSSA-t360 (7.8%), CC30-MSSA/t021(6.3%), MRSA V-t355 (6.3%), CC8-MRSA III/t421 (4.7%), CC1-MRSA V-t267 (4.7%), and CC/ST15-MSSA-t084 (3.1%). The genetic diversity and prevalent multidrug resistance indicate that the resistance situation of S. aureus recovered from mobile phones in Tehran is severe, posing a potential threat to patients, the community, and healthcare settings.

Everyday Life in the Tropics
Authors: Karlsson Håkan , Gustafsson Thomas
Published: April 2024

Swedish emigration to the US during the second half of the nineteenth century and the beginning of the twentieth century is well documented by historians and statisticians, but this is not the case with Swedish emigration to Cuba, which is largely unknown. This article introduces the project Everyday Life in the Tropics: The “Forgotten” Swedish Immigrant Colony in Bayate, Cuba and the results of its initial fieldwork at the former colony of Bayate and its surroundings in November 2022. The objective of this work was to initiate documentation of the material remains of the Bayate colony, which flourished from 1905 to 1920 and was finally dissolved in the 1930s, through a survey of the remains of buildings and other structures and investigating the extent and nature of these for future research. It is stressed that the areas inside and outside the nucleus of the colony hold huge potential for further archaeological investigations/excavations, and for studying the social and material aspects of the everyday life of the colonists, through the combination of historical, archaeological, anthropological and botanical evidence. It is also possible to focus on the colonists’ construction of identities due to their cross-cultural interactions with Cuban society, and on how these eventually led to social and material continuity or change.

Introduction: Bariatric surgery has become an increasingly common procedure, especially for patients with morbid obesity who have obtained unsatisfactory results from conventional treatments. Objective: To evaluate the occurrence of behavioral patterns and personality disorders in patients in the preoperative period of bariatric surgery. Materials and methods: Cross-sectional study carried out with 146 patients from a medium-sized clinic, a reference in the execution of bariatric surgeries in the Midwest region of Minas Gerais, Brazil. Data collection was performed using the psychological instrument entitled Factorial Personality Battery. Descriptive analysis and data association were performed. Results: Half of the participants presented high or very high scores for greater propensity to develop depression and anxiety, showing a close relationship with personality disorders, especially with behavioral patterns of effort and dedication. Discussion: The patterns of effort and dedication behavior are protective factors in the postoperative period, taking into account the adaptations and new habits necessary for a good recovery and maintenance of weight loss. Conclusions: The dysfunctional patterns of behavior that stood out most are related to greater difficulty in perceiving the positive side and ease in perceiving the negative side, leading to a more intense experience of suffering, in addition to difficulty in making decisions and facing routine challenges. Screening behavioral patterns and personality disorders preoperatively is necessary for adequate patient monitoring and successful bariatric surgery.

NUMERICAL INVESTIGATION OF THE NEAR HEAD-ON COLLISION DYNAMICS OF NON-NEWTONIAN DROPLETS: A COMPARATIVE STUDY USING THE VOLUME OF FLUID AND THE LOCAL FRONT RECONSTRUCTION METHOD
Authors: Llamas Cristina García , Durubal Penbe Merve , Huijgen Arie , Buist Kay , Kuipers Hans , Baltussen Maike
Published: April 2024

Droplet-droplet interactions of highly viscous liquid suspensions have a major impact on industrial
processes such as spray drying, fuel combustion, or waste treatment. The efficiency of these processes depends heavily on the morphology of the droplets after the collision (i.e., surface area and volume). Although often encountered, the physical mechanisms governing merging and break-up of non-Newtonian droplets are largely unknown. It is therefore of paramount importance to gain a better understanding of the complex physics dominating the collision of non-Newtonian droplets.
In this research, we investigate numerically the collision of droplets using the local front reconstruction
method (LFRM) and the volume of fluid (VOF) method. The coalescence and stretching separation regime are studied using a xanthan solution, whose shear-thinning rheology is described with the Carreau-Yasuda model. The capabilities of the two methods to capture the complex topological changes are assessed by a one-to-one comparison of the numerical results with experiments for near head-on collisions at various We numbers.
UNCERTAINTY ANALYSIS FOR EVOLUTION EQUATIONS
Authors: Marino Greta , Pichler Alois , Pietschmann Jan-Frederik
Published: April 2024

The paper studies uncertaintly quantification for evolution equations with various time-dependent parameters that
evolve as stochastic processes. Instead of a sensitivity analysis, we measure functionals of the solution, the so-called quantities of interest, by involving scalarizing statistics. The nested distance respects the evolutionary aspect of the problem at hand. Motivated by applications in pedestrian dynamics, we apply these results to drift-diffusion equations in the case when the total mass is-due to boundary or reaction terms-not conserved. We first provide existence and stability for the deterministic problem and then involve uncertainty in the data, which results in Lipschitz continuity with respect to the nested distance. Finally, we present a numerical study illustrating these findings.
MOTIVES AND TACTICS: REPRESENTATIONS OF ASPIRATIONAL CAPITAL AMONG MARGINALIZED-IDENTITY STEM STUDENTS
Authors: Sausner Erica B. , Pitarresi James M.
Published: April 2024

While engaging supports offered through a scholarship program, marginalized-identity STEM students draw on community cultural wealth to persist in an environment that is not designed for their success. This analysis focuses on the presence of aspirational capital: hope and goals that prevail despite systemic barriers for marginalized-identity individuals and communities. Semi-structured interview data from 31 students, through the engagement of basic qualitative methodology, reveal students' ongoing search and adaptation for institutional opportunities, engagement of individualistic tactics including keen self-awareness and narratives of "hard work" to meet established goals, relationships to trusted guides, and community-serving orientations as representations of their aspirational capital.
A Politics of Working-Class Culture and the Culture of Working-Class Politics: The Aesthetics and Activism of Amber Film and Photography Collective and the Berwick Street Film Collective
Authors: Boyall Jessica Williams
Published: April 2024

This paper examines how Amber Film and Photography Collective’s working-class affiliations and Berwick Street Film Collective’s middle-class makeup shaped their divergent approaches to depicting ‘working-class issues’ by drawing on the films of both collectives, alongside archival materials and oral testimonies. By engaging in a comparative reading, I highlight the breadth of Amber’s oeuvre, tracing the development of their filmmaking strategies—which included agitprop, the fusion of factual and fictional formal elements and transnational collaboration with the German DemocraticRepublic’s film production company, Deutsche Film-Aktiengesellschaft (DEFA)—to demonstrate that, contrary to criticisms levelled by contemporary theorists clustered around Screen magazine and the British Film Institute, Amber transcended the constraints of Documentary Realism by incorporating radical avant-garde aesthetics into their oppositional practice. Concomitantly, Amber’s radical filmmaking is positioned as relative to its members’ working-class solidarities, with their concern for championing working-class cultures contrasted with Berwick Street’s broader political agendas. Through foregrounding this politics/culture dialectic, the practical repercussions of Berwick Street’s middle-class representation of ‘working-class interests’ are investigated while the theoretical criteria by which avant-garde depictions of ‘working-class issues’ are evaluated are themselves assessed.
Söz ve Ötesi: Söz, Müzik, Ritüel İlişkisine Ontolojik (Kozmik) Bir Yaklaşım
Authors: Sayın Fatma
Published: April 2024

Dini ritüeller belirli zamanlarda, belirli formlarda gerçekleştirilen tarihsel olaylardır. Dini ritüellerin olay karakteriyle pratiğe yön vermesi ile dini ve felsefi üst anlatıların ritüelleri zihinsel/ideolojik olarak konumlandırması arasında bir ayrım söz konusudur. Bu ayrım aynı zamanda ritüellerin anlamı konusunda bazı belirsizliklere yol açmaktadır. Antik/ilkel düşünce, insan varlığını bütün (kozmos) içinde ele aldığı için, ritüeli kozmolojinin bir temsili olarak anlamlandırmıştır. Bu bütünsellik insanın kendi sınırlarına ve sınırların ötesine dikkat çekerek en temelde sınır tecrübesini görünür hale getirmiştir. Bu açıdan ritüel, bir sınır çizme ve sonra sınırı aşma süreci olarak formasyon, deformasyon ve transformasyon gibi boyutlara sahiptir. Bu yazımızda ritüelin olay formunda insanın farklı boyutlarını dikkate alarak insanın kendisini anlamasına ve dönüştürmesine imkân hazırladığını vurgulayacağız. Bu imkân bağlamında Türk-İslam kültüründeki mevlid, Alevi semahı ve Mevlevî âyininin farklı yönlerini ele alacağız. Mevlid ritüelinde katılımcının mevlidin olağanüstülük anlatısıyla bir transformasyon sürecine girdiğini ifade edeceğiz. Alevî semahında ise bedensel formasyonun mekânsal temsili olarak ritüele dikkat çekeceğiz. Alevî semahının yerellik evrensellik ikilemine karşılık Mevlevî âyininde şehir kavramının sembolik formasyonuna dikkat çekeceğiz. Mevlevî âyininde kozmik birliğin sembolik tezahürü olarak şehir ve ritüelin karşılıklı etkileşimini analiz etmeye çalışacağız.
School Administrators’ and Teachers’ Views on Change Fatigue: Turkish Educational System Case
Authors: Balyer Aydin , Özcan Kenan
Published: April 2024

The main purpose of this study was to determine school administrators and teachers’ views on change fatique in education. The research was conducted with a qualitative research method. The study employed a phenomenological research design. The participants of the research were 10 school administrators and 15 teachers determined with purposive sampling technique. The data were collected with semi-structured interview technique and analyzed with content analysis technique. In this process, main themes, sub-themes and codes were developed. The research results revealed that both school administrators and teachers have experienced too many changes without getting informed, prepared, trained and motivated accordingly. These frequent changes create change fatigue, pressure and stress on both school administrators and teachers. In addition, as they do not participate in decision-making process of these changes, they are not implementing these decisions willingly. It is recommended that school administrators and teachers should participate in decisions, be supported, informed and trained about the change process.
La Langue János (Jean Baptist Lalangue): „A’ magyarországi orvos vizekről, és a’ betegségekbenn azokkal való élésnek szabott modjairól” írt könyvének (Nagykároly, 1783) változatai.
Authors: Borda Lajos
Published: April 2024

A luxemburgi születésű (1743), Bécsben orvosdoktori diplomát szerzett Jean Baptist Lalangue-re tanára, Gerard van Swieten (1700–1772), a Habsburg Birodalom egészségügyének szervezője hívta fel Mária Terézia figyelmét. Tanulmányai befejeztével az uralkodó kinevezte Varasd vármegye főorvosának. Lalangue elsajátította a horvát nyelvet, és élete végéig hivatalában maradva (1799) Varasdon élt és működött. Munkássága kiterjedt a gyógyvizek leírására, 1779-ben Zágrábban latinul és horvátul egyaránt könyve jelent meg Horvátország és Szlavónia vizeiről (Tractatus de aquis medicatis regnorum Croatiae et Slavoniae). E munka párdarabja a magyarországi gyógyvizekről készült, és a nagykárolyi Károlyi Nyomdában jelent meg 1783-ban latinul: De aquis Hungariae medicatis, és magyarul: A’ magyarországi orvos vizekről, és a’ betegségekbenn azokkal való élésnek szabott modjairól címmel. Lalangue e művének alapul szolgált Heinrich Johann Nepomuk von Crantz (1722–1799) 1777-ben megjelent Die Gesundbrunnen der Österreichischen Monarchie című munkája. A nyomdát a latin és a magyar nyelvű kiadás megjelenésekor Joseph Sigismund Klemann bérelte, aki 1782 és 1797 között volt bérlő. Klemannról sokat nem tudunk, annyit azonban igen, hogy részeges volt és figyelmetlenül dolgozott, erre utal itt ismertetett könyve is. A nyomtatvány több magán- és közgyűjteményben megtalálható. Könyvtáramban két, eltérő terjedelmű változat van.
The Determinants of Sustainable Innovation Expansion Strategy: the Case Study of Companies from a Declining Industry
Authors: Толстов Никита
Published: April 2024

Stimulation and improvement of innovative development is an extremely important component of economic growth in an economy, along with the companies’ competitiveness in stagnating industries, which is especially relevant for companies at the maturity stage of the life cycle, where the risk of transition to the decline stage is highest. Without new developments and a sustainable innovation strategy, a company loses its leading position in the industry and misses new opportunities, leading it to the stage of stability and decline. Thus, it is important to study the factors that contribute to R&D intensity and encourage innovations in detail. This study investigates the impact of high level and quality of companies’ patent activityon their financial potential in order to maintain stable innovation performance in the medium term. The sample comprises companies from the printer and camera sector between 2007 and 2020. The determinants of innovation expansion that characterize the technological readiness and market potential of firms to maintain their leading position in a highly competitive market are identified, using a case study method using the example of Canon and its competitor Xerox. The data are collected from Bloomberg and Orbis Patent Database. The results show that while high innovation activity is an important driver of growth, it does not always lead to better financial performance in the earlier stages of the life cycle. The study contributes to the literature by examining different characteristics of innovation activity and life cycle stages through the lens of external economic changes, which brings transparency and clarity in understanding the possible problems that may result from using already disclosed innovations of competitors as well as disclosing one’s own intellectual property rights. The study proves that the greatest effect of innovation activity is observed in companies whose R&D expenditures are close to the industry average values along with diversification of revenue. The results of the study can help policy makers, managers and shareholders to build effective corporate governance to achieve strategic goals and minimize the risks of making wrong management decisions in R&D investments.
