Numerical Analysis of Non-Sphericity of Particles of Powder Material and their Effect on Packing Structure for Concentrated Solar Power Applications
Authors: Boribayeva Aidana , Gvozdeva Xeniya , Golman Boris
Published: March 2024

Concentrated solar power technology represents a novel approach to generating solar power, characterized by high solar radiation density and uninterrupted operation. To store thermal energy and extend system operating hours, concentrated solar power systems rely on thermal energy storage. Selecting the appropriate heat storage media is crucial for designing a cost-efficient and straightforward system capable of withstanding high processing conditions. Among many powder materials, bauxite powder stands out as alternatives to conventional molten salt for thermal storage media due to its widespread availability and suitability for operating conditions. Particle shape, particularly its sphericity, plays a vital role in efficiently packing particles which directly affects to heat transfer properties. To investigate this effect, three samples of particles with different shape were formed: spheres, ellipses, and cylinders using Discrete Element Method with equal volume and material properties, and only variation of their sphericity factors. The study focused on the analysis of the porosity of the packed bed of particles with different shapes and its influence on the packing structure properties. The analysis of local packing fraction revealed that elliptical and cylindrical particles samples exhibited reduced heap formation and a more uniform distribution along z direction during vertical packing. The coordination number and radial distribution function analyses for these non-spherical particles showed a greater number of contacts between particles and disordered distribution of particles due to mechanical interlocking of non-spherical particles. The results indicated that the deviation of sphericity has a positive impact on the denser packing of particles generated more contacts and higher local packing fraction.

Authors: Jerabek Jan
Published: March 2024

In the field of construction, with regard to social and design requirements, it is necessary to look for innovative and advanced solutions for the materials of building and structural elements. The topic of this paper is precisely from this area, where material engineering and the field of concrete belong. The aim of the research task is to compare the properties of three different mixtures. The main goal is the analysis and comparison of samples after exposure of test samples to elevated temperatures of up to 900 °C. The mixtures are based on the same ingredients. The first mixture was a reference one, where the binder was Portland cement. In the second mix, cement was replaced, and an alkali-activated binder was used. And in the third mix, which was a modification of the first mix, part of the aggregate was replaced with light artificial aggregate. The experimental part also focused on testing and comparing the workability in the fresh state and subsequently the basic mechanical characteristics, which include strength in compression, split tension, or static modulus of elasticity. In addition, tests of resistance to frost and defrosting chemicals or determination of the tear strength of the surface layer on the test beams were also carried out.

Published: March 2024

Extensive research is currently focused on finding alternative treatment for bone regeneration, due to the complexity and risks associated with existing procedures. One such alternative under investigation is the utilization of biodegradable nanofiber membranes, fabricated using an electrospinning method. In this study, polycaprolactone (PCL) was used as the main matrix to form electrospun membranes at different electrospinning parameters with the incorporation of estradiol to address bone regeneration capability. The effects of estradiol incorporation within the PCL membranes while determining the appropriate electrospinning parameters through morphological, chemical functionalities and wettability analyses were investigated. The inclusion of estradiol into the PCL matrix has reduced the nanofiber diameter and improved the wettability properties of the membranes. The alterations of electrospinning voltage and flow rate also impacted on the reduction of fiber diameter and wettability, which highlights the membrane’s potential for further cell attachment and bone regeneration.

Authors: Choi Hea Lim , Yang Juyeon , Lee Hye Sun , Lee Ji-Won
Published: March 2024

Background: Studies have shown that incident albuminuria is associated with insulin resistance (IR); however, an IR marker that best predicts the prevalence of albuminuria has not yet been established. This study explored the association between IR and incident albuminuria using various IR indices, including the homeostasis model assessment of IR (HOMA-IR), metabolic score for IR (METS-IR), and triglyceride-glucose (TyG) index, and compared their predictive abilities for the prevalence of albuminuria.Methods: A total of 4,982 Korean adults from the 2019 Korea National Health and Nutritional Examination Survey were analyzed. The odds of albuminuria were determined using the quartiles of the IR indices. Receiver operating characteristic (ROC) curves were used to calculate the area under the ROC curve and predictability. The cutoff values for albuminuria detection were also computed.Results: An increase in the quartiles of all three IR indices was associated with incident albuminuria, even after full adjustment for covariates (HOMA-IR: odds ratio [OR], 1.906; 95% confidence interval [CI], 1.311–2.772; P=0.006; METS-IR: OR, 2.236; 95% CI, 1.353–3.694; P=0.002; TyG index: OR, 1.757; 95% CI, 1.213–2.544; P=0.003). The area under the ROC curve for incident albuminuria based on the HOMA-IR, METS-IR, and TyG indices was 0.594 (95% CI, 0.568–0.619), 0.633 (95% CI, 0.607–0.659), and 0.631 (95% CI, 0.606–0.656), respectively. The optimal cutoff values for predicting albuminuria were 2.38, 35.38, and 8.72 for the HOMA-IR, METS-IR, and TyG indices, respectively.Conclusion: The METS-IR and TyG indices outperformed HOMA-IR in predicting incident albuminuria.
Colorizing Multi-Modal Medical Data: An Autoencoder-based Approach for Enhanced Anatomical Information in X-ray Images

Published: March 2024

Colourisation is the process of synthesising colours in black and white images without altering the image’s structural content and semantics. The authors explore the concept of colourisation, aiming to colourise the multi-modal medical data through X-rays. Colourized X-ray images have a better potential to portray anatomical information than their conventional monochromatic counterparts. These images contain precious anatomical information that, when colourised, will become very valuable and potentially display more information for clinical diagnosis. This will help improve understanding of these X-rays and significantly contribute to the arena of medical image analysis. The authors have implemented three models, a basic auto-encoder architecture, and two combined learnings of the autoencoder module with transfer learning of pre-trained neural networks. The unique feature of this proposed framework is that it can colourise any medical modality in the medical imaging domain. The framework’s performance is evaluated on a chest x-ray image dataset, and it has produced benchmark results enabling high-quality colourisation. The biggest challenge is the need for a correct solution for the mapping between intensity and colour. This makes human interaction and external information from medical professionals crucial for interpreting the results.

Алгебрами Клини называются структуры со сложением, умножением и константами $0$ и $1$, задающими идемпотентное полукольцо, и операцией итерации Клини. В частном случае $*$-непрерывных алгебр Клини итерация Клини определяется инфинитарным образом как супремум степеней элемента. В работе получены результаты об алгоритмической сложности хорновых теорий (семантического следования из конечных множеств гипотез) коммутативных $*$-непрерывных алгебр Клини. А именно, доказана $\Pi_1^1$-полнота их хорновой теории и $\Pi^0_2$-полнота ее фрагмента, где в гипотезах нельзя использовать итерацию. Эти результаты являются коммутативными аналогами соответствующих теорем Д. Козена (2002) для общего (некоммутативного) случая. Также получены несколько сопутствующих результатов.

Submission to Episciences

Lot sizing is important in production planning. It consists of determining a production plan that meets the orders and other constraints while minimizing the production cost. Here, we consider a Discrete Lot Sizing and Scheduling Problem (DLSP), specifically the Pigment Sequencing Problem (PSP). We have developed a solution that uses Genetic Algorithms to tackle the PSP. Our approach introduces adaptive techniques for each step of the genetic algorithm, including initialization, selection, crossover, and mutation. We conducted a series of experiments to assess the performance of our approach across some multiple trials using publicly available instances of the PSP. Our experimental results demonstrate that Genetic Algorithms are practical and effective approaches for solving DLSP.

Le dimensionnement de lots tient une place importante en planification de production en industrie. Il consiste à trouver un plan de production qui à la fois satisfait les demandes et autres contraintes tout en minimisant les coûts de production.

Nous avons développé une approche basée sur les algorithmes génétiques afin de le résoudre. Notre approche propose des méthodes adaptatives pour chacune des étapes des algorithmes génétiques que sont l'initialisation, la sélection, le croisement et la mutation. Les expériences menées nous ont permis d'évaluer la performance de cette approche sur des instances en accès publique de PSP. Les résultats obtenus montrent que les algorithmes génétiques constituent une approche intéressante et effective dans la résolution des DLSP.
Poder esquecer. O esquecimento como acontecimento e como possibilidade ontológica em Heidegger
Authors: Borges-Duarte Irene
Published: March 2024

O esquecimento é uma experiência incómoda da quotidianeidade. Marca de temporalidade e de finitude, tem carácter ontológico e alcance ôntico. Manifesta o caminho da verdade do ser à maneira humana e do ser no mundo de tudo quanto há. Heidegger define esse caminho ontológico incontornável como sendo o da metafísica ocidental, hoje culminante na época da técnica. Mas, numa abordagem meta-ontológica, o fenómeno ontológico de poder esquecer constitui uma possibilidade para o existir de cada um, enquanto projecto. O não-esquecimento compulsivo-obsessivo inibe o a-vir, reduzindo-o a interpretações sedimentadas, pre-determinadas por situações hermenêuticas do sido, congeladas num não-passado. A presente abordagem pretende considerar esta duplicidade do possível e do não-possível, radicada no olvido e na abertura afectiva, ao encontro e ao seu novum, assim habilitado. Para tal, parte de um quadro de Klee e de uma narrativa de Borges, para orientar a leitura de textos de Heidegger, desde 1927 a 1945.
Entre miedos y esperanzas, el aporte de Heidegger para una historia conceptual de la emoción.
Authors: Ferioli Nicolás
Published: March 2024

La historia conceptual de Koselleck es un instrumento al servicio de una teoría de la historia que busca desarrollar categorías que hagan inteligible por qué acontecen y cómo pueden cumplimentarse las historias. Estas categorías se desprenden del análisis existencial de Heidegger cuya determinación antitética fundamental delinea el horizonte de temporalidad e historicidad. El artículo propone una reflexión genealógica en torno a la voz emoción en tanto concepto antropológico fundamental del lenguaje científico moderno. Con ello, perseguimos el objetivo de ampliar la oferta de categorías que definen nuestras experiencias de finitud; es decir, proponemos incorporar el fenómeno afectivo como fundamento antropológico básico y, de este modo, desarrollar el par dicotómico de miedo y esperanza en tanto categorías metahistóricas cuya fluctuación moviliza tensiones, conflictos y fracturas que revelan la estructura temporal de la existencia.

Published: March 2024

This work deals with semi-analytical and numerical methods to solve a class of fractional order Volterra-Fredholm integro-diﬀerential equations. First, a semi-analytical method is proposed using the Chebyshev and Bernstein polynomials in the Adomian decomposition method. The uniqueness of the solution and convergence of the method are proved. Further, we solve the model using a numerical scheme comparing the L1 scheme for the fractional order derivative in combination with appropriate quadrature rules for the integral parts. Numerical experiments are done by the proposed methods to show their eﬃciency through a few tabular data and plots. Some comparisons with the existing results show that the proposed methods are highly productive and reliable.
Impact of Nominee Agreement on Mining Business Entities Against the Welfare of the People
Authors: Sumarsih Ida
Published: March 2024

This study delves into the regulation of foreign share ownership and the prohibition of nominee agreements in the establishment of mineral and coal mining entities in Indonesia, aiming to ensure legal certainty and promote the welfare of the people, as mandated by Article 33 paragraph (3) of the 1945 Constitution. Employing three legal theories—basic legal values (Gustav Radbruch), legal system theory (Lawrence Friedman), and the welfare state—the research method incorporates both normative juridical and empirical juridical approaches. The findings reveal that nominee agreements, though legally questionable under Article 1320 of the Civil Code, serve as a means for foreign investors to secure their interests in Indonesian mining ventures. An Environmental Analysis of Law (EAL) employing the Cost-Benefit Analysis (CBA) method indicates a positive impact on the welfare of communities in Morowali and Kutai Kartanegara regencies due to these agreements. Proposing an ius constituent approach, the study advocates for relaxed foreign ownership regulations, allowing up to 51% ownership during the initial establishment period, accompanied by a mandatory divestment to 49% after ten years of exploration. Such a policy shift obviates the need for nominee agreements, ensuring both investment security and legal clarity. Supervisory mechanisms are recommended to oversee divestment and reinvestment processes, ensuring equitable distribution of mining dividends and bolstering legal certainty in mining operations. These proposed regulatory adjustments are envisioned to foster equitable resource management, thereby advancing the welfare of the Indonesian populace, particularly in Morowali and Kutai Kartanegara regencies.

Authors: Shamim Syed Jazib , Nasim Misbah Mohammad , Shah Haider
Published: March 2024

Middle East is one of the critical regions in global politics and diplomacy. The economic development of this region has attracted the attention of superpowers, especially the US, to have its influence in these countries by establishing military and economic connections. The US enjoyed enormous influence in this region with no competition. China is exponentially expanding its economic might and may surpass the US in a few years in terms of the world’s biggest economy. China has also stepped into diplomatic fronts and established cordial ties with the Middle Eastern nations, mainly due to its economic projects. Recently, China brokered a peace deal between Saudi Arabia and Iran, which has led to the restoration of diplomatic relations between both arch-rivals of the Middle East. This has been a significant breakthrough in the politics of the Middle East and significantly boosted China’s diplomatic presence in the region. This research examines the Chinese involvement in the Middle East, its economic and diplomatic initiatives, and how China has enabled itself to emerge as a peacemaker in the region. This research also sheds light on the evolving dynamics of Middle East politics and its consequences on the interests of the US.

Published: March 2024

Diabetes mellitus is a biochemical condition with various genetic and environmental aspects described by persistently high glucose levels with aggravation of fat, sugar, and protein metabolic activity due to flaws in insulin release, insulin activity, or both. All humans and several other species have four major blood types, i.e. A, B, AB, and O. The study seeks to ascertain the existence of a link between ABO blood types, Rh factor and diabetes mellitus in district Swabi of Khyber Pakhtunkhwa, Pakistan. A six-month survey was conducted from July 2022 to December 2022. Individuals’ sociodemographic data was collected at random using self-administered questionnaires. Clinical data was collected in the laboratory. The information was then entered and analysed using the 2020 edition of SPSS. The Chi-Square test was implemented to calculate the results. Blood type B and Rh positive are more common, with a p-value for their link with diabetes less than 0.05 in the control group. The higher frequency and lower p-values indicate that diabetes mellitus and blood group B and Rh positive are positively correlated. It is suggested that this topic be expanded in other districts to comprehend the relationship of Rh and ABO blood types with diabetes mellitus.

Authors: Karasimav Özlem , Kutay Ordu Gökkaya Nilüfer , Alemdaroğlu Ebru , Utku Burkay , Ergün Nilgün
Published: March 2024

Objective: Novel Coronavirus Disease 2019 (COVID-19) pandemic has affected the whole world and still host many obscurities. Researches involving athletes investigated the lifestyle, athletic performance and psychological alterations compared to pre-pandemics and returning-to-sports process. But, knowledge about the past symptomatic COVID-19 effects on athletic performance is immature. Athletes are prone to asymptomatic or mild symptomatic COVID-19 rather than severe form; so this study aimed to compare the muscular athletic performance, cardiorespiratory function and psychological condition after COVID-19 between asymptomatic and mild symptomatic athletes.

Materials and Methods: This case-control designed study recruited a total of 40 young adult male long-distance runners who survived COVID-19 asymptomatically (n=20), and with mild symptoms (n=20). All of the subjects had completed the isolation period and been approved to return-to-sports. The age, anthropometric properties, athletic license term and dominant hand and foot sides of the subjects were recorded. The muscular strength of upper limb, isokinetic and isometric muscular strengths of lower limb flexor and extensors, and VO2max were measured. The self-reported depression, anxiety and COVID-19-related fear were evaluated.

Results: The values of all muscular strength parameters, VO2max and anxiety level were similar between the groups (p>0.05). However, the levels of depression (p=0.048) and COVID-19-related fear (p=0.012) were significantly higher in mild symptomatic group in comparison with asymptomatic (p<0.05).

Conclusions: Mild symptomatic COVID-19 did not affect muscular athletic performance and cardiorespiratory fitness, but caused psychological disorder in comparison with asymptomatic infection. In case of COVID-19, the psychological state of the athlete should be paid close attention. We suggest the supply of adequate and quick psychological support while targeting the previous level of physical fitness and athletic performance in the returning-to-sports process.

Published: March 2024

Experimental investigations are currently exploring the impact of adding porous layers within burner housing on thermal and exergy efficiency. Specifically, the focus is on understanding the significance of double layers on porous media combustion and how it can improve fuel mixing and flame stability. Premixed butane-air combustion in rich conditions was examined using three different sizes of burners (i.e., 23 mm, 31 mm, and 44 mm) porous media with equivalence ratios ranging from ф = 1.3 to 2.0. The experimental findings revealed a substantial improvement in performance efficiency (thermal and exergy) as the equivalence ratio increased. This study reveals that smaller burner diameters (ID, inner diameter = 23 mm) provide greater efficiency than larger ones (ID = 31 mm and 44 mm). The maximum flame temperature and porous wall temperature are found to decrease as the equivalence ratio increases. The highest temperature measured was 924.82°C for 23 mm, 910.23°C for 31 mm, and 850.76°C for 44 mm at ф = 1.3. Lastly, the thermal and exergy efficiency in a 23 mm porous media burner (PMB) is higher at ф = 2.0 at 84.30% and 83.47%, respectively. It can be concluded that the diameter size of the burner and equivalence ratio for double-layer porous material influence the performance (efficiency) of PMB.

School management is currently understood from the democratic and participatory principle, resulting in a more complex perception of the school manager’s participation in the success of the students’ learning process. In this sense, the perception of the concept of school manager has become broader, involving all aspects that directly or indirectly influence the quality of education in a given school institution. In this context, this article seeks to investigate how the continued training of school managers influences the quality of management performance and, consequently, the development of pedagogical planning that cooperates with the insertion of pedagogical practices based on the use of ICT and the adoption of a methodology from an innovative perspective.

Mục tiêu: Tìm hiểu một số yếu tố tiên lượng tử vong ở bệnh nhân chảy máu não có giãn não thất cấp. Thiết kế nghiên cứu: nghiên cứu hồi cứu. Phương pháp nghiên cứu: Nghiên cứu trên 110 bệnh án của bệnh nhân chảy máu não có giãn não thất cấp vào khoa Cấp cứu từ tháng 1 năm 2015 đến hết tháng 6 năm 2018. Kết quả: tuổi trung bình của người bệnh là 56, nam giới chiếm đa số 66,7%, bệnh hay gặp người có tiền sử tăng huyết áp (58,2%). Điểm Graeb, áp lực trong sọ, điểm hôn mê Glasgow là những yếu tố độc lập với tiên lượng tử vong ở bệnh nhân chảy máu não thất có giãn não thất cấp. Khi áp lực trong sọ tăng mỗi 1mmHg thì nguy cơ tử vong tăng gấp 1,9 lần. Mỗi điểm Graeb tăng thì nguy cơ tử vong tăng 22 lần. Mỗi điểm hôn mê Glasgow giảm thì nguy cơ tử vong tăng gấp 2,5 lần. Kết luận và khuyến nghị: Cần phối hợp chặt chẽ giữa lâm sàng, cận lâm sàng và chẩn đoán hình ảnh để định hướng điều trị và xác định tiên lượng tử vong sau chảy máu não thất có giãn não thất cấp.

Mục tiêu: Mô tả một số đặc điểm lâm sàng, cận lâm sàng và đánh giá kết quả điều trị bệnh nhân ung thư buồng trứng loại tế bào hạt tại bệnh viện K. Đối tượng và phương pháp nghiên cứu: Nghiên cứu mô tả hồi cứu kết hợp tiến cứu trên 44 bệnh nhân u buồng trứng đã được phẫu thuật và xét nghiệm mô bệnh học tại bệnh viện K, chẩn đoán sau mổ là u tế bào hạt buồng trứng từ năm 2014-2022. Kết quả: Độ tuổi trung bình là 51,7 ± 13,3 tuổi, thể mô bệnh học gặp nhiều nhất là u tế bào hạt týp trưởng thành (97,2%). Kích thước u của u tế bào hạt là 11,23±5,65cm (từ 3,5 cm đến 25cm). Bệnh nhân u tế bào hạt giai đoạn I chiếm ưu thế với 50% và giai đoạn II chiếm 20,5%, giai đoạn III chiếm 29,5%. Trung bình thời gian theo dõi là 47,8 ± 24,7 tháng (từ 10,8-94,4 tháng), tỉ lệ sống thêm toàn bộ (OS) và sống thêm không bệnh (DFS) 5 năm ở nhóm bệnh nhân u tế bào hạt lần lượt là 90,9% và 79,4%. Giai đoạn I có DFS 5 năm lớn hơn giai đoạn II-III (100% so với 54,1%), sự khác biệt có ý nghĩa thống kê với p< 0,001, không có tổn thương còn lại sau phẫu thuật có DFS 5 năm cao hơn có tổn thương còn lại sau phẫu thuật (94,7% so với 0%), sự khác biệt có nghĩa thống kê với p< 0,001. Các yếu tố khác như tuổi, kích thước u không có sự khác biệt có ý nghĩa thống kê lần lượt có p là 0,091 và 0,706 (p > 0,05). Kết luận: U tế bào hạt là loại ung thư buồng trứng ít gặp với phân bố tuổi rộng rãi, với phần lớn gặp ở giai đoạn sớm và có tiên lượng tốt. Giai đoạn bệnh và tổn thương còn lại sau phẫu thuật là yếu tố tiên lượng quan trọng của u tế bào hạt.
