Preliminary Experiences in Determining the Soil–Water Characteristic Curve of a Sandy Soil Using Physical Slope Modeling
Authors: Peranić Josip , Vivoda Prodan Martina , Škuflić Rea , Arbanas Željko
Published: July 2024

Relating soil moisture content to soil suction, the soil–water characteristic curve (SWCC) represents an essential feature in unsaturated soil mechanics that enables estimation of different unsaturated soil property functions and modeling of the macro-scale soil behavior. However, depending on the soil and processes under consideration, proper hydraulic characterization of a soil through direct laboratory measurements can be difficult, time-consuming, and involve many uncertainties. In the case of uniformly graded sands, there is a highly nonlinear and steep shape of the SWCC, with only a few kPa of soil suction separating saturated and residual soil moisture conditions, which makes measurements for determinations of SWCC especially challenging. This study encompasses an investigation of the sandy type of soil’s behavior and presents some preliminary results and experiences on the determination of SWCC through the use of physical slope model tests. The 30 cm deep slope, inclined at 35 degrees and instrumented with soil moisture and pore water pressure sensors, was exposed to series of rainfall intensities, ranging from 37 up to 300 mm/h. The results indicated that the data on hydraulic response in monitored points are not only useful for the determination of SWCC, but that the approach is useful for investigation of hydraulic hysteresis phenomena, as well as its effects on soil moisture and pore water pressure conditions, which also affects the stability conditions of a slope. In particular, the best-fit parameters of the van Genuchten model suggested air entry values of 1.6 and 1.1 kPa for the drying and the wetting curves of the SWCC, respectively, with the two branches shifted by about 1 kPa of soil suction.

Published: July 2024

The use of pumps as turbines has been gaining more and more attention in recent years. The present work mainly investigates the influence of blade wrap angle on the internal flow and pressure fluctuation characteristics of centrifugal pumps as turbines. Five different wrap angles (35°,45°, 55°, 65°, and 75°) for a forward-curved impeller were numerically analyzed under multiple operating conditions. The accuracy of numerical simulation was validated by experimental results. The results show that maximum efficiency is achieved with a blade wrap angle of 35°, and the highest efficiency flow point gradually decreases as the blade wrap angle increases. It is found by conducting entropy production theory analysis that the high-entropy production rate regions in PATs are concentrated in the volute tongue and impeller blade inlet regions, and that the entropy production rate at the impeller inlet region increases and then decreases as the blade wrap angle decreases. In addition, pressure pulsation was affected not only by dynamic and static interference but also by an irregular vortex around the impeller; its magnitude under Qt is higher than 0.8Qt for blade wrap angles of 55° and 75°. The primary frequency of pressure pulsation within the impeller is the axial frequency fn and its multiples, and the frequency with the largest amplitude is 3fn. The periodicity of vortices is closely related to the periodicity of pressure pulsation. And it is suggested that a PAT with a 35° blade wrap angle is advantageous for improving the stability of a turbine.

Historically, water utilities have relied on tried-and-true practices in the design and operation of their infrastructure, tapping new resources and expanding networks as needed. However, as the effects of climate change and/or urbanization increasingly impact both water supply and demand, utilities need new, holistic planning and management approaches. Integrated planning approaches must account for changing policies, technological progress, and unique, setting-specific operating conditions. Based on this notion, an international web seminar with faculty, researchers, and students from nine universities across five continents was conducted. In the 3-month seminar, participants were split into groups and tasked with developing future-proof, sustainable water management solutions for fictitious settings with unique resource availability, climate change predictions, demographic, and socioeconomic constraints. The goal of the seminar was to combine participants’ unique perspectives to tackle challenges in developing future water infrastructure, while forming lasting relationships. Water management concepts became more daring or “out-of-the-box” as the seminar progressed. Most groups opted for a holistic approach, optimizing existing infrastructure, integrating decentralized water management, furthering digitization, and fostering the adoption of innovative policy and planning strategies. To gauge their impact on the evolution of ideas, group dynamics and communication were observed throughout the seminar. As a result, the findings serve not only as a compendium of ideas and concepts for holistic design in the water sector, but also facilitate international collaboration, improve communication in cross-cultural teams or guide the development of training programs in water management for researchers, professional engineers, or water utilities.

Published: July 2024

Deformation effectively represents the structural integrity of concrete dams and acts as a clear indicator of their operational performance. Predicting deformation is critical for monitoring the safety of hydraulic structures. To this end, this paper proposes an artificial intelligence-based process for predicting concrete dam deformation. Initially, using the principles of feature engineering, the preprocessing of deformation safety monitoring data is conducted. Subsequently, employing a stacking model fusion method, a novel prediction process embedded with multiple artificial intelligence algorithms is developed. Moreover, three new performance indicators—a superiority evaluation indicator, an accuracy evaluation indicator, and a generalization evaluation indicator—are introduced to provide a comprehensive assessment of the model’s effectiveness. Finally, an engineering example demonstrates that the ensemble artificial intelligence method proposed herein outperforms traditional statistical models and single machine learning models in both fitting and predictive accuracy, thereby providing a scientific and effective foundation for concrete dam deformation prediction and safety monitoring.

Published: July 2024

An innovative payload containing a sensitive mid-wave infrared camera was flown on an uncrewed aircraft system (UAS) to acquire thermal imagery along a reach of the Sacramento River, California, USA. The imagery was used as input for an ensemble particle image velocimetry (PIV) algorithm to produce near-continuous maps of surface flow velocity along a reach approximately 1 km in length. To assess the accuracy of PIV velocity estimates, in situ measurements of flow velocity were obtained with an acoustic Doppler current profiler (ADCP). ADCP measurements were collected along pre-planned cross-section lines within the area covered by the imagery. The PIV velocities showed good agreement with the depth-averaged velocity measured by the ADCP, with R2 values ranging from 0.59–0.97 across eight transects. Velocity maps derived from the thermal image sequences acquired on consecutive days during a period of steady flow were compared. These maps showed consistent spatial patterns of velocity vector magnitude and orientation, indicating that the technique is repeatable and robust. PIV of thermal imagery can yield velocity estimates in situations where natural water-surface textures or tracers are either insufficient or absent in visible imagery. Future work could be directed toward defining optimal environmental conditions, as well as limitations for mapping flow velocities based on thermal images acquired via UAS.

Published: July 2024

Administrative strategies to cope with drought are steadily changing, from emergency procedures to day-to-day monitoring. More consideration must be paid to long-term and preventive drought control measures in the future. This paper discusses the risk of hydrological drought in the Yellow River Basin. The standardized runoff index (SRI) was used to characterize hydrological drought, and the run theory was used to identify drought states and quantify drought characteristic variables. Based on the drought severity and duration, a drought development plan was proposed and a three-dimensional copula function was constructed to obtain the joint distribution function of three-dimensional drought characteristic variables. A drought risk assessment system based on the loss × probability risk theory was constructed to explore the spatial and temporal characteristics of hydrological drought risk in the Yellow River Basin. Finally, according to the risk assessment results, the risk level was divided into low, medium and high risk, and a Bayesian network was used to explore the probability of hydrological drought. The main results are as follows: (1) From 1960 to 2018, the severity of hydrological drought in the Yellow River Basin increased, the duration lengthened, and the development speed accelerated. (2) The hydrological drought risk in the Yellow River Basin showed an overall upward trend, with the fastest increase in the HJ region of 0.041/10a. The highest annual average drought risk in the TDG region is 0.598. (3) The spatial transmission of hydrological drought risk is divided into three types: constant, enhanced and mitigation types, of which the constant type is the most common. The transmission probabilities of low, medium and high risk of hydrological drought from the HYK region to the low, medium and high risk of hydrological drought in the LJ region are 0.68, 0.66 and 0.78, respectively.

Published: July 2024

Microalgae-based water treatments for the removal of different types of pollution have been gaining considerable attention during the last few decades. However, information about microalgae potential in the removal of pharmaceuticals and personal care products (PPCPs) and the ecotoxicological outcomes is still limited. Therefore, in this work, we aimed at investigating salicylic acid removal from water by three different microalgae strains, namely Chlorella sorokiniana, Chlorella vulgaris and Scenedesmus obliquus. For such a purpose, photobioreactors were operated under batch and semi-continuous mode. Apart from determining the reduction in the concentration of salicylic acid attained by each strain, we used zebrafish embryo bioassays to assess the efficiency of microalgae to reduce its toxicity effects. S. obliquus was the strain that achieved the most significant decrease in the concentration and toxic effects of salicylic acid. Indeed, S. obliquus was able to rescue mortality and reduce abnormalities at practically 100%. The efficiency of C. sorokiniana and, especially, that of C. vulgaris were not so remarkable, indicating that the removal of SA and its toxic effects from water by microalgae is markedly strain dependent. The obtained results proved the importance of considering toxic effects for a more comprehensive evaluation of microalgae efficiency in the removal of PPCPs in view of an adequate selection for water treatment.

Published: July 2024

Water scarcity poses significant challenges in arid regions like the Middle East and North Africa (MENA) due to constant population growth, considering the effects of climate change and water management aspects. The desalination technologies face problems like high energy consumption, high investment costs, and significant environmental impacts by brine discharge. This paper researches the relationships among water scarcity, energy-intensive desalination, and the development of renewable energy in MENA, with a particular focus on the Gulf Cooperation Council (GCC) countries. It examines innovations in solar-powered desalination, considering both solar photovoltaic (PV) and solar thermal technologies, in combination with traditional thermal desalination methods such as multi-effect distillation (MED) and multi-stage flash (MSF). The environmental impacts associated with desalination by brine discharge are also discussed, analyzing innovative technological solutions and avoidance strategies. Utilizing bibliometrics, this report provides a comprehensive analysis of scientific literature for the assessment of the research landscape in order to recognize trends in desalination technologies in the MENA region, providing valuable insights into emerging technologies and research priorities. Despite challenges such as high initial investment costs, technical complexities, and limited funding for research and development, the convergence of water scarcity and renewable energy presents significant opportunities for integrated desalination systems in GCC countries. Summarizing, this paper emphasizes the importance of interdisciplinary approaches and international collaboration by addressing the complex challenges of water scarcity and energy sustainability in the MENA region. By leveraging renewable energy sources and advancing desalination technologies, the region can achieve water security while mitigating environmental impacts and promoting economic development.
Development of an Ecosystem Model Considering Sediment Redox Processes in Enclosed Water Bodies
Authors: Koue Jinichi
Published: July 2024

This study investigates enclosed water bodies to understand the intricate interactions among physical, chemical, and biological processes. A one-dimensional model, integrating sediment and ecosystem components, was developed to analyze oxygen depletion, nutrient dynamics, and the influence of sediment organic matter on oxygen concentrations due to stratification. Oxygen and nutrient concentrations were derived by combining results from a one-dimensional vertical diffusion model with the ecosystem model. The dissolution, adsorption, and desorption of inorganic substances in bottom mud react differently under anaerobic and aerobic conditions, necessitating separate formulations for reduction and oxidation reactions in the bottom mud model. In Lake Biwa, Japan’s largest lake, dissolved oxygen levels have decreased despite regulatory efforts since the 1970s, prompting an investigation into the causes of oxygen-depleted water masses. The model was thus applied to examine oxygen consumption in Lake Biwa’s deep sediments, shedding light on anoxia in enclosed water bodies. This study emphasizes the significance of bottom sediments in water quality models and their implications for ecosystems. Furthermore, the adaptive nature of this model allows for its application in various water bodies, including freshwater reservoirs, lakes, and saltwater bays.

Since ancient times, dams have been built to store water, control rivers, and irrigate agricultural land to meet human needs. By the end of the 19th century, hydroelectric power stations arose and extended the purposes of dams. Today, dams can be seen as part of the renewable energy supply infrastructure. The word dam comes from French and is defined in dictionaries using words like strange, dike, and obstacle. In other words, a dam is a structure that stores water and directs it to the desired location, with a dam being built in front of river valleys. Dams built on rivers serve various purposes such as the supply of drinking water, agricultural irrigation, flood control, the supply of industrial water, power generation, recreation, the movement control of solids, and fisheries. Dams can also be built in a catchment area to capture and store the rainwater in arid and semi-arid areas. Dams can be built from concrete or natural materials such as earth and rock. There are various types of dams: embankment dams (earth-fill dams, rock-fill dams, and rock-fill dams with concrete faces) and rigid dams (gravity dams, rolled compacted concrete dams, arch dams, and buttress dams). A gravity dam is a straight wall of stone masonry or earthen material that can withstand the full force of the water pressure. In other words, the pressure of the water transfers the vertical compressive forces and horizontal shear forces to the foundations beneath the dam. The strength of a gravity dam ultimately depends on its weight and the strength of its foundations. Most dams built in ancient times were constructed as gravity dams. An arch dam, on the other hand, has a convex curved surface that faces the water. The forces generated by the water pressure are transferred to the sides of the structure by horizontal lines. The horizontal, normal, and shear forces resist the weight at the edges. When viewed in a horizontal section, an arch dam has a curved shape. This type of dam can also resist water pressure due to its particular shape that allows the transfer of the forces generated by the stored water to the rock foundations. This article takes a detailed look at hydraulic engineering in dams over the millennia. Lessons should be learned from the successful and unsuccessful applications and operations of dams. Water resource managers, policymakers, and stakeholders can use these lessons to achieve sustainable development goals in times of climate change and water crisis.
GPs’ perspectives on diagnostic testing in children with persistent non-specific symptoms: a qualitative study
Authors: Mulder Lianne JW , Ansems Sophie M , Berger Marjolein Y , Blok Guus CGH , Holtman Gea A
Published: July 2024

Background

Diagnostic testing is prevalent among children with persistent non-specific symptoms (PNS), and both undertesting and overtesting have negative consequences for child and society. Research in adults with PNS has shown that GPs use diagnostic testing for reasons other than diagnosis, but comparable research has not, to the best of our knowledge, been conducted in children. Understanding GPs’ perspectives of testing decisions in children could provide insights into mechanisms of undertesting and overtesting.

Aim

To investigate GPs’ perspectives of conducting or refraining from diagnostic testing in children with PNS and the differences compared with their motives when treating adults.

Design and setting

Qualitative study using semi-structured interviews with Dutch GPs.

Method

We purposively sampled GPs until data saturation. Reasons for conducting or refraining from diagnostic tests were explored using two real-life cases from daily practice. Online video interviews were transcribed verbatim. Data were collected and analysed concurrently by thematic content analysis.

Results

Twelve GPs participated. Their decision making involved a complex trade-off among four themes: medical considerations (for example, alarm symptoms), psychosocial factors (for example, doctor–patient relationship), consultation management (for example, ‘quick fix’), and efficient resource utilisation (for example, sustainability). Compared with when treating adults, GPs were more hesitant to conduct diagnostic testing in children because of their higher vulnerability to fearing invasive procedures, lower probability of organic disease, and reduced autonomy.

Conclusion

As in adults, GPs’ decisions to conduct diagnostic tests in children were motivated by reasons beyond diagnostic uncertainty. Educational programmes, interventions, and guidelines that aim to change the testing behaviours of GPs in children with PNS should target these reasons.
Safety-netting advice documentation in out-of-hours primary care: a retrospective cohort from 2013 to 2020
Authors: Edwards Peter J , Finnikin Samuel , Wilson Fay , Bennett-Britton Ian , Carson-Stevens Andrew , Barnes Rebecca K , Payne Rupert A
Published: July 2024

Background

Providing safety-netting advice (SNA) in out-of-hours (OOH) primary care is a recognised standard of safe care, but it is not known how frequently this occurs in practice.

Aim

Assess the frequency and type of SNA documented in OOH primary care and explore factors associated with its presence.

Design and setting

This was a retrospective cohort study using the Birmingham Out-of-hours general practice Research Database.

Method

A stratified sample of 30 adult consultation records per month from July 2013 to February 2020 were assessed using a safety-netting coding tool. Associations were tested using linear and logistic regression.

Results

The overall frequency of SNA per consultation was 78.0% (1472/1886), increasing from 75.7% (224/296) in 2014 to 81.5% (220/270) in 2019. The proportion of specific SNA and the average number of symptoms patients were told to look out for increased with time. The most common symptom to look out for was if the patients’ condition worsened followed by if their symptoms persisted, but only one in five consultations included a timeframe to reconsult for persistent symptoms. SNA was more frequently documented in face-to-face treatment-centre encounters compared with telephone consultations (odds ratio [OR] 1.77, 95% confidence interval [CI] = 1.09 to 2.85,P= 0.02), for possible infections (OR 1.53, 95% CI = 1.13 to 2.07,P= 0.006), and less frequently for mental (versus physical) health consultations (OR 0.33, 95% CI = 0.17 to 0.66,P= 0.002) and where follow-up was planned (OR 0.34, 95% CI = 0.25 to 0.46,P<0.001).

Conclusion

The frequency of SNA documented in OOH primary care was higher than previously reported during in-hours care. Over time, the frequency of SNA and proportion that contained specific advice increased, however, this study highlights potential consultations where SNA could be improved, such as mental health and telephone consultations.

Published: July 2024

Background

Routine primary care data may be a valuable resource for preconception health research and to inform the provision of preconception care.

Aim

To review how primary care data could provide information on the prevalence of preconception indicators and examine associations with maternal and offspring health outcomes.

Design and setting

Systematic review of observational studies using UK routine primary care data.

Method

Literature searches were conducted in March 2023 using five databases to identify observational studies that used national primary care data from individuals aged 15–49 years. Preconception indicators were defined as medical, behavioural, and social factors that may impact future pregnancies; health outcomes included those that may occur during and after pregnancy.

Results

From 5259 screened records, 42 articles were included. The prevalence of 37 preconception indicator measures was described for female patients, ranging from 0.01% for sickle cell disease to >20% for each of advanced maternal age, previous caesarean section (among those with a recorded pregnancy), overweight, obesity, smoking, depression, and anxiety (irrespective of pregnancy). Few studies reported indicators for male patients (n= 3) or associations with outcomes (n= 5). Most studies had a low risk of bias, but missing data may limit generalisability of the findings.

Conclusion

The findings demonstrated that routinely collected UK primary care data could be used to identify patients’ preconception care needs. Linking primary care data with health outcomes collected in other datasets is underutilised, but could help to quantify how optimising preconception health and care could reduce adverse outcomes for mothers and children.

Conflicto e identificaciones etno-raciales en la antesala colonial del caudillismo y las rebeliones montoneras
Authors: Escolar Diego
Published: July 2024

Este texto desarrolla algunos de los aportes del libro El país indiviso. Poblamiento, conflictos por la tierra y mestizajes en Los Llanos de La Rioja durante la colonia, de Roxana Boixadós y Judith Farberman, para comprender la historia colonial de la región y, sobre todo, su proyección para el análisis de la movilización política rural en el siglo XIX. No pretende ser una reseña, sino un comentario que rescata su análisis sobre la emergencia y evolución de la propiedad indivisa y la importancia de los conflictos que esta formación económica y social implicó para la beligerancia de Los Llanos en el período post independentista. Aborda también su indagación sobre los usos de las categorías étnicas o raciales entre mediados del siglo XVIII y principios del XIX, dialogando con algunas de las conclusiones que derivan de los mismos. En particular, la necesidad de profundizar en el desacople de las categorías como representaciones colectivas que establecen diferencias del mestizaje como proceso biológico o cultural concreto, y relativizar la idea de homogeneización étnico-racial hacia principios del siglo XIX como una de las bases de la movilización política popular, en vistas a una explicación regional de las montoneras más allá de Los Llanos.

Don Cándido Sotomayor y su consistencia en la percepción de la calidad
Authors: Guzmán Florencia
Published: July 2024

Durante veintiséis años, el cura de Los Llanos, don Cándido Sotomayor, llevó a cabo una labor de ordenamiento y clasificación del curato que resulta sorprendente dada la dinámica de cambio constante que caracterizaba a esa comunidad hacia finales del período colonial. En este sentido, pareciera que su labor no consistió en una mera reclasificación de la población, sino más bien en una categorización personal y consistente basada en los criterios implícitos de percepción de la calidad. Las categorías utilizadas por Sotomayor revelan tanto los valores arraigados en su posición en la jerarquía social como los cambios en los imaginarios raciales vigentes y su resignificación hacia el final de la era colonial. Es importante resaltar, en sintonía con lo expresado por las autoras, las oportunidades que el análisis de la labor de Sotomayor brinda para examinar los enfoques a través de los cuales los censistas observaban la realidad. Asimismo, permite contrastar percepciones, consistencias y reforzamientos de ciertos atributos implícitos de la calidad a lo largo del tiempo. Esta mirada detallada sobre el trabajo y los criterios de clasificación del religioso nos ofrece una ventana única para comprender cómo se construía y percibía la calidad en esa época, así como para analizar los cambios y continuidades en las valoraciones sociales y raciales a lo largo del periodo colonial.

Este trabalho considera dois processos industriais, nomeadamente a energia eólica (turbinas eólicas) e a mineração (triturador) para estudar as emissões de gases com efeito de estufa utilizando dois métodos da Indústria 4.0, tecnologias imersivas e gémeos digitais. É apresentada uma metodologia de trabalho que permite a integração de realidade estendida e gêmeos digitais para estudar a pegada de carbono de turbinas eólicas e trituradores de mineração no sul do Equador. Na primeira etapa é produzido um desenho CAD de uma turbina eólica e um britador de mandíbulas como um todo. Essas montagens são movidas para uma plataforma, para interagir MediaPipe com Unity ou Unreal Engine 4 para realidade aumentada com inteligência artificial. Consequentemente, o modelo é alimentado com dados armazenados em um banco de dados e depois através de um sistema inteligente, ou seja, aprendizado de máquina, o modelo gera diferentes cenários de processos. Finalmente, a redução das emissões de gases de efeito estufa é justificada de alguma forma pela aplicação destas metodologias a setores estratégicos no Equador, como energia e mineração. Numa segunda etapa, seguindo os dados de funcionamento de cada uma das máquinas reais, pretende-se gerar uma base de dados para treinar um modelo de inteligência artificial, que ajude a prever o funcionamento dos processos estudados em diferentes cenários de trabalho.

يهدف البحث إلى دراسة المكان من منظور مختلف، ينطلق من حضور المعالم العمرانية فيه؛ فكما تتأثر العمارة بالسرد في تركيبها، وتقنياتها، وتنظيمها، يستفيد السرد من العمارة في استثمار عناصرها،  ومقولات التصميم الخاصة بها، وهو بعد مهم، إلا أن البحث يُعنى بمسار مختلف، يركز على معمارية المكان، وإشاراته السيميائية؛ وعندها يتخذ المعلم المعماري بعدًا جديدًا، يمكن قراءته من منظور يؤول إلى أصله المعماري، ويؤسس لتحوله السردي.
وتتضمن مشكلته قراءة تجليات العمارة في أربع روايات سعودية، تعاملت معها من زوايا مختلفة، وغدت مؤثرة في بنيتها، ومضمونها، وهي: (ليلة واحدة في دبي)، و(الأفق الأعلى)، و(حكومة الظل)، و(حُبّى).
ويعتمد البحث في منهجه الآليات العامة للتحليل السيميائي، والسيميائية الثقافية؛ حيث السياقات التي تحكم توظيف العمارة في الرواية، لتتجاوز وظائفها التواصلية المعتادة إلى البحث في العلاقات التي تحكم هذه الصروح المعمارية؛ بوصفها أنساقًا سيميائية تنطلق من أبعاد ثقافية متجانسة، ومختلفة، ومتنوعة في الوقت نفسه.
وقد توصل البحث إلى أن الأبعاد المعمارية على اختلافها، سواء تعلقت بالتصميم الذي يسبق المعمار أم بالمعمار نفسه؛ تجاوزت المدلولات الواقعية الثابتة لها، إلى ما تؤسسه من بناء تخييلي له دلالات سيميائية وثقافية تقترن بالنصوص السردية نفسها، وترتبط بعناصرها من مكان وزمان، وأحداث وشخصيات، ورواة؛ مما أسلمنا إلى تنوع في وظائفها حسب علاقتها بالنصوص نفسها؛ من التشكيل السردي للعمارة الحديثة، إلى العمارة بين التاريخ والتخييل، ثم معمارية المكان في الفضاء الصوفي.
وبعد،  فلما كانت العمارة حقلًا سيميائيًا وثقافيًا؛ فإنه يمكن استثمارها في المقاربات النقدية لنماذج شعرية أو سردية أخرى؛ بحيث تستفيد من سيميائية الأصل، وتربطه بعوالم التخييل.
A Cultural History of the Greek Digital Games Origins: From Clones to Originality
Authors: Theodoropoulos Maximos S.
Published: July 2024

Literature on the digital games industry and gaming history has for the most part focused on the global production centres of North America, Western Europe, Japan, and, lately, China. However, in recent years, a call to research the diverse and less dominant national contexts within which digital games are produced has been addressed. In this article, we shed light on early digital game development in Greece, covering the years between 1982 and 2002. This particular region has been highly neglected by both domestic and international researchers. We approach Greek digital game development from both historical and cultural perspectives, through an investigation of how local game developers interact with a wide range of contextual facets in a complex interrelation between global and national conditions. This article argues that, in order to highlight the characteristics of early national game production cultures and digital games design, one must examine them as well under the broader cultural production ecosystem, along with the economic and institutional contexts and transformations within which digital game production takes shape.

У статті визначено та схарактеризовано проблеми, що мають місце в процесі навчання дітей мігрантів першого й другого покоління у країнах Західної Європи. Розглянуто різні покоління дітей мігрантів. З’ясовано негативні впливи, які характерні для дітей мігрантів, – обмежений доступ до соціально-економічних ресурсів, наявність міграційного статусу, низький соціально-економічний статус, обмеженість знань місцевої мови, наявність психологічних бар’єрів, недостатня підтримка сім’ї та громади.

Визначено причини низької шкільної успішності учнів мігрантів, а саме: недосконалість навчальних програм; суб’єктивне ставлення до оцінювання тестів; обмеженість фінансових можливостей щодо надання підтримки; перебування учнів мігрантів у школах, які мають низькі показники успішності; направлення даної категорії учнів до оволодіння професійно-технічною освітою; відсутність належної уваги до дітей мігрантів з боку держави та інших регіональних і місцевих структур; наявність мовних бар’єрів.

Проведене дослідження дозволило окреслити шляхи реалізації питань успішного навчання дітей мігрантів, як-от: створення привітного дитячого середовища, що вільне від расизму; задоволення різноманітних психосоціальних потреб дітей; розв’язання їхніх лінгвістичних потреб.

Установлено, що школам належить провідна роль у процесі соціалізації дітей мігрантів. Успішна інтеграція цієї категорії дітей у освітнє середовище школи залежить від розумного керівництва закладом освіти та всебічної підтримки органами управління освітою й урядом.

З’ясовано основні проблеми щодо організації навчання дітей мігрантів у країнах Західної Європи. Це: існування мовних бар’єрів як у школі, так і в оточуючому середовищі; непідготовленість вчителів до організації навчання дітей із сімей мігрантів; зосередженість учнів мігрантів у школах із низькими показниками успішності; неналежна фінансова підтримки зазначеної категорії дітей та їхніх сімей; слабка взаємодія батьків зі школою; існування психологічних перешкод, таких як: почуття ізоляції, відчуження, упередження; недостатнє розуміння урядом потреб дітей мігрантів; слабке задоволення їхніх психосоціальних та емоційних потреб; відсутність варіативних програм щодо вивчення англійської мови; слабке володіння мовою при вивченні різних шкільних предметів та деякі інші
Effective Cancer Diagnosis through High-Dimensional Microarray Data Analysis by Integrating DCT and UFS
Authors: Efe Enes
Published: July 2024

Cancer remains a global health challenge, with various types such as lung, breast, and colon cancer posing significant threats. Timely and accurate diagnosis is crucial for effective treatment and improved survival rates. Genetic research offers promising avenues in the fight against cancer, as identifying gene mutations and expression levels enables the development of targeted therapies and a deeper understanding of disease subtypes and progression. This study investigates a novel hybrid method aimed at improving the accuracy and efficiency of cancer diagnosis and classification. By combining Discrete Cosine Transformation (DCT) and Univariate Feature Selection (UFS) methods, the feature selection process is optimized for the dataset. The extracted features are then rigorously tested using established classifiers to assess their effectiveness in cancer classification. The proposed method's performance was evaluated using eight distinct datasets, and metrics such as MF1, K-score, and sensitivity were calculated and compared with various methods in the literature. Empirical evidence demonstrates that the proposed method outperforms others on 5 out of 8 datasets in terms of both accuracy and computational efficiency. The presented method represents a reliable tool for cancer diagnosis and classification.

Hypertension can be referred to as a condition when the systolic blood pressure exceeds 140 mmHg and the diastolic blood pressureexceeds 90 mmHg, as measured on two occasions with a five-minute interval, while the individual is in a state of sufficient rest andcalm. The use of 3-month injectable birth control containing progesterone can increase blood pressure. Increased blood pressure inbirth control participants can be overcome pharmacologically and non-pharmacologically. The aim of the investigation was to analyzethe administration of a mixture of tomato juice (Solanum lycopersicum) and star fruit (Averrhoa carambola L.) Against lowering bloodpressure in injectable Kb acceptors for 3 months. The research design used an experimental approach one group pretest and posttest.Sampling technique with purposive sampling, the number of samples is 30 people. The statistical test employed is the t-test. Theresearch showed 24 (80%) respondents had a decrease in blood pressure and 6 (20%) respondents had a fixed blood pressure withan average systole change of 130.00 mmHg and diastole 85.17 mmHg. The findings of Paired Samples T-Test obtained a significancevalue of 0.000 (p < 0.05) which means that there is an influence of giving a mixture of Tomato Juice (Solanum lycopersicum) and StarFruit (Averrhoa Carambola L.) At acceptor kb inject 3 months. This is influenced by the content of potassium as an antidiuretic so thatit can reduce sodium levels in the urine by the kidneys

Published: July 2024

This study focused on the steadily increasing proportion of corporate transactions in the total apartment transaction volume. It also investigated the correlation between this proportion and apartment prices. The analysis confirmed a positive relationship between the corporation's share in apartment transaction volume and the apartment sales index. In particular, the direction of this relationship varied depending on the corporation's market participation status. When a corporation participated as a seller (buyer), it positively (negatively) correlated with the apartment sales index. This study has implications for achieving the policy goal of curbing speculative demand from corporations. However, the system must be restructured to incentivize corporations to actively engage in real estate transactions as sellers to ensure price stability in the real estate market.
