Authors: Uslu Emine , Erden Abdulsamet , Bol Oğuzhan , Karagöz Hatice
Published: December 2024

Amaç: Obstruktif uyku apne sendromu (OUAS), üst solunum yollarında tam veya kısmi tıkanma ile hava akışının bozulması ile
solunumda duraksama veya hava akışında azalmayla karakterize bir hastalıktır. OUAS’ta sistemik inflamatuvar belirteçlerin
arttığı ve buna bağlı hematolojik parametrelerde değişiklik olabileceği bilinmektedir. Çalışmamızda amacımız Uyku Merkezine
başvuran ve OUAS düşünülerek polisomnografi yapılan hastaların hematolojik parametrelerini değerlendirmektir.
Gereç ve Yöntemler: Bu çalışmada Uyku Merkezine başvuran ve OUAS düşünülerek polisomnografi yapılan, 18 yaş ve üzeri
351 hastanın dosyası tarandı. Hastalar Apne-Hipopne indeksine göre basit horlama veya OUAS olarak gruplandı. Hastaların
hematolojik parametreleri dosyalarından kaydedildi. OUAS varlığı ile bu parametrelerdeki değişiklikler değerlendirildi.
Bulgular: 271 hasta OUAS tanısı alırken, 78 hasta basit horlama kabul edildi. OUAS tanısı alan hastaların yaş ortalaması
50,46±11,08 idi. Beyaz küre sayısı, ortalama trombosit hacmi ve eritrosit dağılım genişliği açısından gruplar arasında
istatistiksel olarak anlamlı fark saptanırken, hemoglobin düzeyi, nötrofil sayısı, lenfosit sayısı ve nötrofil lenfosit oranı
açısından fark yoktu.
Sonuç: OUAS hematolojik bulgularda değişikliklere neden olabilecek kronik bir hastalıktır. Hematolojik bulgularda oluşabilecek
değişikliklerin daha büyük hasta grubunda, prospektif olarak yapılması, polisomnografi gibi zor ulaşılan bir tetkiki kimlere
daha öncelikli yapalım sorusunun yanıtını daha ucuz ve kolay ulaşılabilir bir testle belirlememize olanak verebilir.

Authors: Çakır Nuri , Akça Keklikcioğlu Sinem
Published: December 2024

Aim: Human papillomavirus (HPV) infection is the most common sexually transmitted infection and is known to cause cervical
cancer. The World Health Organization (WHO) recommends HPV-DNA-based molecular tests as primary screening tests. In
our study, we aimed to investigate the frequency and genotype distribution of HPV in women over the age of 18 who applied to
our hospital’s gynecology and obstetrics outpatient clinic and lived in our region.
Materials and Methods: 1026 patients over the age of 18 who applied to the gynecology and obstetrics outpatient clinic of our
hospital between 2022 and 2024 were included in the study. The results of patients whose cervical swab samples were taken,
HPV DNA screening was performed, and whose laboratory results were known were evaluated retrospectively.
Results: HR-HPV positivity was detected in 32 (2.8%) of 1026 female patients included in our study. In positive patients, HPV16
positivity was detected in 1.4% of the patients, while HPV18 positivity was found in 0.9% and other 12 HR-HPV genotype
positivity was found in 0.6%. It was observed that the highest number of applications and positive results were detected in 2024.
It was reported that HPV16 positivity was the most common genotype in patients in all years.
Conclusion: : Prevalence studies provide important data in determining strategies to prevent HPV infection and its related
cancers. In our country, screening programs need to be delivered to a wider audience and studies need to be carried out in this
context.

Banco Mundial e educação neoliberal: análise do relatório “Educação: Um tesouro a descobrir” (Brasil, 2010)
Authors: Mendes Lavínia de Sousa Almeida
Published: December 2024

A partir da análise do relatório Educação: Um tesouro a descobrir (Delors, 1990), este artigo problematiza a forma como o Banco Mundial (BM) influencia na implementação e regulação das políticas educacionais no Brasil. O relatório produzido pela comissão coordenada por Jacques Delords afirma, sob o ponto de vista ideológico, a lógica sociometabólica do capital, e, com isso, este documento simboliza o marco conceitual central do século XXI ao lançar as bases teóricas que seriam os fundamentos do modelo de educação apoiado pelos órgãos internacionais. Com isso, a educação passa a ser vista como parte de uma agenda global e é percebida por sua funcionalidade em forjar uma geração de trabalhadores ajustados ao contexto da reestruturação produtiva. As reflexões propostas direcionam-se à crítica ao modelo de escola neoliberal, reprodutivista, desigual e não emancipatória.

Revealing the relationships of trust in chatbot applications in the accommodation sector with consumer innovativeness and purchase intention
Authors: Tanriverdi Haluk , Çıkı Kartal Doğukan
Published: December 2024

Objective: The approaches of innovative consumers who have benefited from the chatbot applications of accommodation businesses operating in Istanbul to chatbot applications have been examined. The aim of the research is to determine whether there is a relationship between consumers' trust in chatbot applications and their level of innovativeness and purchase intentions.Method: The sample of the research was reached by convenience sampling method and the questionnaire application was carried out. 417 usable questionnaires were obtained and then the data were analyzed by correlation analysis and difference tests.Originality/Relevance: There is a lack of studies linking consumer innovativeness and trust in chatbot applications, especially in tourism and hospitality research. This research is one of the first attempts to empirically examine the use of chatbot applications, an artificial intelligence technology platform, in hospitality businesses and to empirically examine consumers' trust in the technology and their level of innovativeness along with their purchase intentions.Main results: The results of the research revealed that there is no significant relationship between the "benevolence dimension" of trust in chatbot applications and consumer innovativeness; however, there is a significant relationship between the "competence dimension" and the "honesty dimension" of trust and consumer innovativeness. Similar findings were found between trust in chatbot applications and purchase intention.Theoretical/methodological contributions: Although the results of this research represent a limited area, they show the gap in the relevant literature and provide important clues to industry pioneers.
Thermal diff usivity of soil-peat mixtures: nonlinear dependence on peat content
Authors: Arkhangelskaia Tatiana A. , Telyatnikova Ekaterina V. , Umarova Aminat B.
Published: December 2024

The thermal diffusivity of the upper plow horizon of the urban soil from the territory of MSU Experimental soil station, lowland packed peat, and their mixtures was studied. The soil from Ap horizon was sieved through a 1 mm sieve and mixed with peat in various proportions; the content of peat in mixtures ranged from 1 to 80% by dry weight. Metal cylinders 10 cm high and 3.8 cm in diameter were filled with soil, peat, and soil-peat mixtures. The thermal diffusivity was measured using the unsteady-state method with a working temperature range of 20–26°C. The heating rate of the packed samples was measured after the samples were placed in a liquid thermostat with a constant water temperature. For each sample, a series of measurements was carried out with a step-by-step change in soil water content from the maximum one after capillary saturation of the sample to the minimum one, corresponding to the air-dry state. Within the studied range of water contents, the thermal diffusivity of different samples changed by a factor of 1.3–3.5; the greatest changes with water content were typical for mineral soil. The thermal diffusivity vs. water content dependence was almost linear for peat, and for soil it was an S-shaped curve with a weakly expressed maximum. The lowest thermal diffusivity was obtained for peat and mixtures with high peat contents; the highest one — for soil without peat additions. The non-linear character of the thermal diffusivity vs. peat content dependence was revealed. Small additions of peat to mineral soil resulted in a noticeable decrease in the thermal diffusivity of the mixture; small additions of soil to peat had practically no effect on thermal diffusivity. The thermal diffusivity of the studied substrates increased with increasing sample bulk density and decreased with increasing organic matter content. It was concluded that the patterns typical for soil-peat mixtures are similar to those earlier obtained for peat-sand mixtures, but in the case of soil-peat mixtures these patterns are less clearly expressed.

Authors: Umarova A.B. , Butylkina M.A. , Gasina A.I. , Lyutikova A.I. , Shnyrev N.A.
Published: December 2024

The paper presents the results of experiments to study changes in hydrological properties of soil substrates composing profiles of artificial soils (construktozems) 1-4 years after their creation. Constructozems are represented by two variants - layered soils including Ap horizon, lowland peat and quarry sand of the same thickness, and a mixture of these substrates in an identical amount by weight, as for layered constructozems. Water retention curves obtained by capillarimetric method on samples of undisturbed structure were compared. A decrease in the water-holding capacity of the peat layer and an increase in the mixture samples were found a year after their functioning as part of the artificial soils. Laboratory and field experiments showed a statistically significant difference in water filtration rates of the layered constructozems and the mixture. Sharp boundaries between soil horizons contrasting in their properties reduce water migration rates down to zero values. Obtaining breakthrough curves of potassium ions allowed us to establish that the formation of continuous paths of rapid movement of water and dissolved substances is observed after 4 years of functioning of artificial soils and is most pronounced in constructions with homogeneous soil profile structure.
Granulometric composition of soils: history, development of methods, current state and prospects
Authors: Dembovetsky A. V. , Tyugai Zemfira , Shein Evgenii V.
Published: December 2024

The problems of determination and classification of soils by granulometric composition from the point of view of domestic and international soil science are considered. The development of methods and devices for granulometric analysis of soils was largely promoted by the works of the Department of Soil Physics and Reclamation, on the basis of which the necessity of two stages of granulometric analysis was shown, the all-Russian method of sedimentation analysis of particles by pipette method was founded, with the development of the classification of N.A. Kachinsky and names of soils by granulometry, which are fundamentally different from those generally accepted in the world practice. At present, at the first stage the method of pretreatment with 4% sodium pyrophosphate is widespread, at the second stage — measurement of granulometric composition two approaches are used — sedimentation method and laser diffractometry, which have different physical bases. The difference of final results on granulometric composition of soils is usually associated with different shape and density of solid phase of organic and mineral particles. This paper presents the studies of granulometric composition of agrodernovo-podzolic sandy loam soil (Tver region, VNIIMZ experimental site) with low content of organic matter in comparison of three methods of granulometric composition determination: laser diffractometer, sedimentometric methods of suspension pressure estimation on Pario - ISP+ (Integral Suspension Pressure) device and classical pipette method. Th e laser diffractometer for fine fractions showed systematically underestimated data with the same pretreatment procedure compared to ISP and pipette method. The ISP+ method compared to the classical pipette method gives similar results.

Influence of the Al2O3 abrasive to abrasive blasting on the quality of the bond between the Co-Cr-Mo alloy and the low-temperature polymerisable acrylic
Authors: Wosińska O. , Wołowiec-Korecka E. , Klimek L.
Published: December 2024

The work aims to determine the effect of the grain size of the Al2O3 abrasive used in abrasive blasting on the quality of the joint between the Co-Cr-Mo alloy and acrylic polymerizing at a temperature below 65C (acrylic for the production of dentures by the pouring method).The Co-Cr-Mo Remanium GM 800+ casting alloy (n=30) was subjected to abrasive blasting with Al2O3 grains of 60 m (n=10), 110 m (n=10) and 250 m (n=10) gradation under a pressure of 0.4 MPa, an angle of incidence of the abrasive stream of 45 for 20 s. The parameters of surface roughness, wettability and surface free energy were determined. After combining the alloy with Vertex Castapress acrylic material, the shear strength and fracture of the joint were tested.The size of the Al2O3 abrasive during abrasive blasting significantly affects the bond quality between the materials in question. Acrylic produces a stronger bond when the surface is blasted with alumina of higher gradation: 110 m and 250 m (p<0.05).The paper investigates the effect of joining Co-Cr-Mo alloy and the low-temperature polymerizable acrylic.Co-Cr-Mo casting alloys are frequently and widely used in prosthetic practice.There is no similar comparative analysis in the literature.

Influence of the maintenance on protective properties of firefighters’ helmets under low-impact energy condition
Authors: Walczak A.
Published: December 2024

Helmets are included in the group of personal protective equipment and are used when other hazard control methods are insufficient. They protect against head injuries caused by various environmental factors, e.g. mechanical and thermal loads, as well as flames. Injuries due to falling debris are serious and may be fatal. Taking that into consideration, the basic role of helmets is to absorb impact energy and dissipate it over a greater surface to decrease forces acting on the head. The following work aims to study the influence of maintenance on the energy absorption capacity of firefighters’ helmets.The research was conducted on two helmet models that differ in design, both new ones and maintained for 4 years. Shells of one group of helmets were manufactured using an injection moulding method, while shells of the second group were made as a laminate. Tests were carried out using a drop hammer with the impact energy at the level of 30 J.Maintenance had a significant influence on the energy absorption mechanism. An increase in fragility and decrease in stiffness of a shell was observed, which reduces the protective properties of helmets. It constitutes a real hazard for firefighters.The research results refer to specific helmet models. The influence of the maintenance on the protective properties of other models of helmets may be different.The research results indicate that a visual assessment of firefighters’ helmets’ technical condition is insufficient. The durability of helmets should also be determined by the time of use.The paper contains original research results. According to the author’s knowledge, the results of the influence of maintenance on the protective properties of firefighters’ helmets have not been presented in any scientific publication.
Mathematical modelling of gas nitriding process of steel using cellular automata
Authors: Ratajski J. , Mydłowska K.
Published: December 2024

The primary aim of this research was to develop a mathematical and computational model of the nitriding process for steel using CA cellular automata theory, which enables the modelling of spatial hardness distributions and nitrogen concentrations within the material.The proposed mathematical model consists of two interacting cellular automata: one representing the surface layer of the nitride material and the other describing the spatial distribution of nitrogen. The developed algorithm and model based on CA were implemented in the MATLAB environment, enabling more effective and efficient testing of the created model and its further use.The developed computer model enabled, by changing the values of the CA model parameters, which correspond to the nitrogen diffusion coefficient in alloy steel, nitrogen solubility in iron and the enthalpy of formation and decomposition of iron nitrides, to adapt the model to the description of the nitriding process of 1.2343 (WCL) steel. The model was experimentally verified by comparing predicted hardness profiles with those measured after nitriding.The main limitation of the developed model is the size of the material fragment in which the nitriding process is simulated.High compliance of the results of numerical calculations with the results obtained by experimental measurements was obtained, which predestines the potential usage of CA-based models for scientific and practical applications. The model can be used as part of an optimisation procedure for designing hybrid composite layers for tribological applications, comprising a nitride layer and a coating deposited via Physical Vapor Deposition (PVD) techniques.The added value of the developed model of the nitriding process, based on the concept of CA, is the author’s modification of the transition rules (both for cells in the Moore and von Neumann neighbourhood) in the automaton related to the structural and phase transformations in the nitride material.

From 2019-2021 The Art Museums of Skagen conducted a reestablishment of the bedrooms in the historic house museum Anchers Hus. Challenges regarding lack of historical documentation and original artefacts led the museum staff to discuss the different notions of authenticity. In this article, a review of the concept of authenticity with regards to historic house museums, led to a categorization based on rationalities, held by conservators, curators, and museum visitors respectively. This categorization revealed several diverging understandings of authenticity. The analysis shows how the museum staff managed and negotiated these contested notions of authenticity and exemplifies how a theoretical understanding can help strengthen curatorial praxis.

The aim of this article is to gain practical insights into digital dissemination methods for audio guides and videos at the Lofotr Viking Museum by employing José van Dijck’s (2013) platform analysis and Gunnar Liestøl’s (2006) multimodal rhetorical tools. Feedback from museum guests, gathered through guide interviews and the author’s curatorial experiences, reveals that while the museum offers a fact-based, technology-focused exhibition, its dissemination methods lack adaptation to the medium. Many guests, particularly the elderly, face challenges with audio guides and phone synchronization, prompting discussion on the digital divide’s impact on visitor experience.
Museumssamlingens organisatoriske position, brug og udvikling

Society is constantly changing, and museums need to keep up to stay relevant. The museum collection, however, has been a part of the museum since the early days, and the basic assumption is that the collection still is the foundation of the museum today. The purpose of this paper is to explore the academic debate in six museological journals about this central part of almost all museums, the collection. The aim is to identify the main themes and areas of focus in the literature relating to the museum collection. A literature review has been conducted and from the analysis it is concluded that the collection is seen as a significant component of the organisation and as an actor that seeks to relate to other actors in various networks. However, it is also observed that work can be done in areas that can further position and activate the collection in a contemporary museum. Resources (such as manhours), professionalisation and digitisation are three key concepts.

O artigo analisou como a gestão escolar pode ser transformada em um ambiente dinâmico e inclusivo por meio da integração de tecnologias inovadoras e práticas colaborativas. O objetivo foi investigar de que forma essas práticas contribuem para a construção de comunidades de aprendizagem que promovam o engajamento da comunidade escolar e a formação integral dos estudantes. O tema foi abordado sob a perspectiva da gestão democrática, da tecnologia como ferramenta pedagógica e do papel do gestor e do professor como agentes de transformação. A pesquisa utilizou uma metodologia bibliográfica, fundamentada na análise crítica de fontes teóricas que exploram a relação entre gestão, inovação e inclusão no ambiente escolar. A análise focou na articulação de diferentes referenciais teóricos, identificando conexões entre práticas de gestão, neurociência e formação docente. Concluiu-se que a gestão escolar, quando orientada por práticas democráticas e pelo uso estratégico da tecnologia, é capaz de superar barreiras administrativas e pedagógicas, criando ambientes educacionais mais equitativos e eficazes. Além disso, destacou-se a importância da formação contínua de professores para integrar os avanços tecnológicos ao ensino de maneira significativa. A pesquisa reforçou a necessidade de ampliar estudos empíricos sobre o impacto prático dessas estratégias, especialmente em contextos desafiadores, e propôs caminhos para que a escola responda às demandas educacionais do século XXI.

Introduction: Failed Futures? (Post)-colonial Planning and Future-making in Tanzania
Authors: Lindner Ulrike
Published: December 2024

Future-making and planning as social practices are strongly related to the surrounding society’s political structures and power relations. In this special issue of ZAMANI, we conceptualize future-making as physical changes and social practices that shape future conditions by making future an issue in the present. We analyse how different approaches to the future, and also surprises and unintended side-effects, have informed the politics and practices of planning in Tanzania and its various regions. When we ask: “Failed Futures?” we address future in the plural, a term that has diffused into historical scholarship rather recently and originates from futurology/future studies, known as the interdisciplinary study of possible, desirable, and probable future developments and design options as well as their prerequisites. The term “futures” tries to capture the image of past spaces and different possibilities that historical actors can and could choose. As historians, we generally address past futures in such a sense that we look at past planning and future-making in order to understand the aspirations and hopes that were present at the time period we choose to analyse. Furthermore, if we look at the larger contexts among the future-making designs of past times, then interest groups and conjunctures of certain future horizons become visible and can be historically investigated.
‘Sold Down the River’: Histories of Production, Trade, and Transport along the Waterways of the Kilombero Valley, Tanzania
Authors: Jackson Jonathan M
Published: December 2024

This article considers the centrality of waterways in the Kilombero Valley of Tanzania to the region’s histories of development from above, particularly in terms of infrastructure, crop production, trade, and transport. Early colonial investigations hoped Kilombero’s riverine system might prove a navigable link from the coast to the Southern Highlands. The British colonial era instead focused more on utilising riverine networks for internal goods transport. Throughout these colonial visions – simultaneously ambitious and naïve – the prevalent dug-out canoe was considered unsafe, inefficient, and replaceable by modernised methods. But the canoe – a symbol of indigenous knowledge and practice – prevailed in the wake of failed efforts to effect such change from above. Kilombero’s waterways are indelibly entwined to its environmental, social, and economic landscapes, yet efforts by colonial powers to establish systems of river transport – whether to transport produce from valley depths towards railheads and markets, or as part of wider networks – were repeatedly frustrated. This article first offers a survey of this period of flawed development efforts, and then considers how perspectives on waterways as infrastructure shifted into the postcolonial era through ambitious schemes for hydropower and irrigation, when visions for rail and roads replaced rivers as the means for systematic conveyance. Waterways also complicated communications, and successive governments neglected the impacts of waterways and their annual inundations on the mobility of local communities. While floods brought agricultural fertility, they also destroyed crops and isolated communities, threatening lives and livelihoods. As a coda, the article notes how the first bridge over the Kilombero was only opened in 2018, ending decades of regional isolation and a stream of fatalities from ill-fated ferry crossings, highlighting this contested environment in which much of life was defined by its waters.

Data structures therefore should be conquered for optimal development of computational thinking and general problem solving prowess. Nevertheless, traditional classroom approaches can hardly meet learners’ interest and enlighten them on how the acquired knowledge could be applied in practice. This paper aims to analyze how the introduced Eduplay, an application that comprises educational games and interactive exercises, can be applied to Problem-Based Learning, focusing on problem-solving. The purpose of the study is to determine the extent to which active learning methods contribute to the improvement of students’ interest, comprehension and skill in data structures. This methodology comprised pre- and post-tests with regard to CT and qualitative approach employed in observing the learning participants’ engagement and interactions. The study also shows that with the integration of Eduplay and PBL, students become more engaged effectively and independently, they think critically, and effectively and independently apply the learnt concepts. The above results imply that combining Eduplay and PBL offers not only the transition from classroom knowledge to working experience but also learning in its entirety. This approach presents educators with a new direction that they can use to enhance the learning outcomes of their students in data structures and other computational fields

Introduction: Disposal of heavy metals into the water as a result of industrial development might cause a threat Health and the environment. aim of this study was to assess the uptake of Co2+ from aqueous solutions via NiO/ γ-Al2O3 nano catalysts. Methods: The main variables that affect the percentage of metal removal were assessed. It took about 50 minutes to attain equilibrium for the elimination of Co+2 ions. It was discovered that raising the adsorbate concentration and increasing the surface weight somewhat lowered the removal of cobalt ions. Results: The removal of cobalt ions was shown to depend on temperature,due to ecothermic natural of this prosess increasing temperature associated with decrease the elemination . Conclusions: The adsorption seems to be spontaneous, exothermic, and less random according to calculated values of the thermodynamic functions (∆G, ∆H, and ∆S) of the adsorption. After the data were fitted into a number of kinetic models, including the Elovich model, pseudo-first order, pseudo-second order, and intraparticle diffusion equations, it was discovered that the pseudo-second-order model performed the best at describing the adsorption, with a high correlation factor (R2).
