Published: December 2023

With a high prevalence of stunting in children in the Central Buton District. This study aims to explore the relationship between internal family dynamics and external social relationships affecting children's nutrition. The study was based on the hypothesis that more frequent and qualitative family interactions and involvement in social activities would correlate with a lower risk of stunting. This study used a cross-sectional study design. Analyzing secondary data from the 2021 Family Data Collection (PK21). The study included 6,586 target families as a sample, the analysis included family dynamics as an exposure variable and used the family happiness index formula to identify family interaction and social interaction. The study used logistic regression from Scikit-learn to evaluate the data in the final stage. Data analysis revealed that internal family interactions, although important, showed no statistically significant association with stunting risk (p=0.3699). However, social interaction had a highly significant association with reduced risk of stunting, with a regression coefficient of -1.9934 and Odds Ratio (AOR) of 0.1362 (95% CI: 0.0739 - 0.2510, p<0.0001) in logistic regression analysis. These findings confirm that strong social engagement and community support are key factors in reducing the prevalence of stunting among children in the Mawasangka sub-district. This study concludes that engagement in community social activities has a significant impact on reducing the risk of stunting in children. The findings suggest that interventions aimed at reducing stunting should go beyond intra-family interventions and include increased social interaction and community support to achieve optimal outcomes in stunting prevention.

Authors: Topal Göksel , Tanbay Tayfun
Published: December 2023

In this study, the energy and exergy analysis of the 1220 MW Hamitabat combined cycle power plant (CCPP) that was renovated in 2017 with a 520 million € project is carried out. A thermodynamic model is built by applying the conservation of mass and energy principles and operating data are obtained from the plant operators. Exergy analysis is performed with the exergy balance equation to determine the exergy efficiencies and improvement potentials of all components. Also, parametric analyses are carried out to investigate the methods to enhance the performance of the plant. The plant has thermal and exergy efficiencies of 59.70% and 58.52%, respectively and these values are 13.70% and 13.52% higher than the thermal and exergy efficiencies of the original plant, respectively. Results showed that the combustion chamber (CC) has the highest rate of exergy destruction, and it is responsible for 77.61% of the total irreversibilities. The improvement potential of the CC is found to be 67.992 MW, and the prevention of heat loss from CC can increase the thermal and exergy efficiencies of the plant by 3.88% and 3.80%, respectively. Parametric analyses showed that the plant performance can be enhanced by increasing the inlet temperatures of high- and intermediate-pressure turbines, and decreasing the pressures of condenser and high-pressure turbine.

Alkaptonuria (AKU) is a rare autosomal disorder characterized by the accumulation of excess homogentisic acid (HGA) in connective tissues. Herein, we report the uncommon presentation of degenerative lumbar disc disease occurring in two patients with AKU warranting spinal surgery. We report two cases of symptomatic disc herniation and vertebral canal stenosis, presented with radiculopathy and progressive neurogenic claudication, respectively. During spinal surgery, blackened ligamentum flavum and intervertebral disc raised the suspicion of a metabolic disorder. Re-examination of patients revealed nose and ear cartilage discoloration in only one of them, however, histopathological findings and urinalysis were confirmatory for AKU in both. Notwithstanding the rarity of AKU, spine surgeons must be vigilant in their examination and diagnosis, and should not exclude any possible diagnosis without thorough consideration.

Removal of hydrogen sulfide from biogas using red rock materials
Authors:   , Mrosso, Register
Published: December 2023

In this study, the potential of red rock materials for the removal of hydrogen sulfide from biogas was studied. The rock samples were collected, sieved and organized in various particle size ranges such as 0.32 - 250 µm, 250 - 500 µm, 500 - 750 µm, 750 µm – 1.0 mm and 1.0 - 1.5 mm. These samples were calcined at temperatures of, 500 °C, 750 °C and 1000 °C and then characterized for phase composition by Energy Dispersive X-ray Fluorescent, for surface area by the Brunauer-Emmett-Teller method and surface morphology by Zeiss Ultra Plus Field Emission Scanning Electron Microscopy. The calcined red rock was filled in the bed reactor, and biogas was allowed to pass through the adsorbent while recording the inlet and exit concentration of hydrogen sulfide. The results show that particle size, calcination temperature, adsorbent mass and biogas flow rate influence the removal efficiency and adsorption capacity of red rock. The sample sieved at 0.32 - 250 µm, and calcined at temperature 1000 °C showed high removal efficiency 95% and adsorption capacity of 0.37 g/100 g of the sorbent. Regeneration of spent materials when exposed to air, followed by reuse in the column, appeared to have nearly similar removal efficiency as the original calcined sample. Thus, the overall performance of the materials is promising, which is due to the presence of metals like iron. Therefore, proving the red rock is available material it can be considered as a suitable adsorbent for biogas purification. Keywords: Red rock, Nadosoito, H2S removal, calcination, flowrate and particle size

Estimation of the bond strength between FRP and concrete using ANFIS and hybridized ANFIS machine learning models
Authors: Nguyen Thuy-Anh , Lý Hải Bằng
Published: December 2023

Adaptive Neuro-Based Fuzzy Inference System (ANFIS) and Particle Swarm Optimization (PSO) algorithms were utilized to produce numerical tools for predicting the bond strength between the concrete surface and carbon fiber reinforced polymer (CFRP) sheets. From the relevant literature, a credible database encompassing 242 test specimens was developed, along with six input factors that primarily determine bond strength. These characteristics include the beam's width, the compressive strength of the concrete, the FRP thickness, the FRP modulus of elasticity, the FRP length, and the FRP width. Finally, using conventional statistical metrics, the outputs of the two suggested models (ANFIS and ANFIS-PSO) were compared to the experimental data. Both models were shown to be a good alternative strategy for predicting the bond strength of FRP-to-concrete.

Authors: Le Thanh-Hai , Nguyen Hoang-Long , Pham Cao-Thang
Published: December 2023

This paper develops an Artificial Neural Network (ANN) model based on 96 experimental data to forecast the dynamic modulus of asphalt concrete mixtures. The accuracy of the models was assessed using numerous performance indexes such as the Root Mean Square Error (RMSE), Mean Absolute Error (MAE), Mean Absolute Percentage Error (MAPE), and coefficient of determination (R2). In addition, this study applied the repeated K-Fold cross-validation technique with 10 folds on the training data set to make the simulation results more reliable and find a model with more general predictive power. According to the research findings, the ANN model accurately predicts the dynamic modulus |E*| of asphalt concrete mixtures. Furthermore, the ANN model could successfully predict the dynamic modulus |E*| of asphalt concrete mixtures with a remarkable R2 = 0.989.

Published: December 2023

Filler is one of the mandatory ingredients in asphalt mixture. It also plays a very significant role in influencing the properties and behavior of asphalt concrete. This paper presents the results of laboratory experiments to determine the influence of 4 different fillers (including conventional stone powder, Portland cement, rice husk ash, and fly ash) on some mechanical properties of asphalt concrete with Dmax of 12.5 (AC12.5). The content of filler used in the study was 5% of the total volume of aggregate. The results show that the designed AC with different fillers have the mechanical properties (air void, Marshall stability, flow, and retaining stability) that meet the specification requirements of Vietnam Ministry of Transport Decision No. 858/2014. In which the mechanical properties of AC using conventional stone powder filler are achieved with an overall better and stable effect. Although rice husk ash and fly ash filler also have certain improvements in Marshall stability and air void, AC using rice husk ash and fly ash filler does not meet the requirement of elastic modulus recommended in the Vietnam standard for flexible pavement design 22TCN 211 -06.

Published: December 2023

Blood transfusion is the process of transferring blood or blood products into one`s circulation intravenously. transfusions are used for various medical conditions to replace lost components of the blood. early transfusions used whole blood, but modern medical practice commonly uses only components of the blood, such as red blood cells, white blood cells, plasma, clotting factors, and platelets. Objectives: To assess the Rate of Acute Complications of Blood and Blood products Transfusion among Children at Jaffar Ibn Ouf Hospital, Khartoum, Sudan,2021. Methodology: It was a cross-sectional, Observational, descriptive hospital-based study. Data were collected using a checklist including brief clinical history and examination and laboratory investigation, type of blood transfusion, and short-term complications. Data were cleaned and entered into a Microsoft Excel data sheet and were analyzed using SPSS latest version software. Result: A total of 130 pediatric patients participated in this study their ages ranged from 1-17 years, most of them; 56 (43.1%) were aged less than 5 years. Of most patients, 89 (68.5%) had blood transfusions based on both clinical conditions and lab results, and 24 (18.5%) patients had blood transfusions based on their clinical conditions. In most patients, 124 (95.4%) had a complete transfusion. Only 15 (11.5%) patients developed blood reactions among them 8 (53.3%) patients developed febrile non-hemolytic transfusion reaction, 6 (40%) patients developed an allergic reaction, and 1 (6.7%) patient developed transfusion-related acute lung injury. According to patients’ outcomes; most of them 123 (94.6%) were discharged, and 2 (1.5%) cases of death. Conclusion: The main limitation of this study was that it was conducted in only one hospital,and the results may differ in other hospitals. Although our hospital serves a large geographical catchment area with numerous referrals, we do not know if current data accurately reflect the overall transfusion pattern in other similar health facilities or the country as a whole due to a lack of local comparable data. A multicenter survey is advised because it can provide more data and more solid conclusions.

On the group of automorphisms of the algebra of plural numbers
Authors: Sultanov A. Ya. , Sultanova G.A. , Monakhova O.A.
Published: December 2023

The algebra of dual numbers was first introduced by V. K. Clifford in 1873. The algebras of plural and dual numbers are analogous to the algebra of complex numbers. Dual numbers form an algebra, but not a field, because only dual numbers with a real part not equal to zero have an inverse element.

In this work, automorphisms of algebras of plural numbers, which are a generalization of the algebra of dual numbers, are studied. Algebras of plural numbers were in the center of attention of the professor of Kazan University A. P. Shirokov. Studying the geometry of higher-order tangent bundles, he established that higher-order tangent bundles over smooth manifolds have the structure of a smooth manifold over algebras of plural numbers. This allowed him in the 70s of the twentieth century to construct a theory of lifts of tensor fields and linear connections from a smooth manifold to its tangent bundles of arbitrary order.

In this paper, we study automorphisms of the algebra of plural numbers. It is proved that the set of all automorphisms of the algebra of plural numbers forms a group. The structure of this group is described. The groups of automorphisms of the algebra of plural numbers with small dimension are indicated as examples.

Viên nhai Gừng (100 mg) được bào chế bằng phương pháp nén trực tiếp sử dụng tá dược siêu rã crospovidon (CP). Hai mươi công thức được chuẩn bị và hỗn hợp bột được đánh giá các thông số trước khi nén bao gồm góc nghỉ, tỷ trọng khối, tỷ trọng riêng hạt, chỉ số nén và chỉ số Hausner. Các viên nhai có công thức này được đánh giá về sự thay đổi trọng lượng, độ cứng, độ mài mòn và độ rã. Kết quả cho thấy tất cả các thông số vật lý đều nằm trong giới hạn cho phép của Dược điển Việt Nam V. Công thức viên nhai tối ưu với thời gian rã tối thiểu bao gồm 45.945% MCC (cellulose vi tinh thể), 2.462% CP và 1.951% PVP-K30 (polyvinyl pyrrolidon K30). Hơn nữa, viên nhai và cao chiết nước ép củ Gừng tươi thể hiện hoạt tính ức chế α-glucosidase in vitro tiềm năng với IC50 = 76.4-79.1 µg/mL so với thuốc đối chiếu acarbose (IC50 = 131.6 µg/mL). Tóm lại, việc áp dụng cách tiếp cận RSM đã phát triển thành công viên nhai gừng, có thể mang lại nhiều ưu điểm khác nhau với phương pháp sản xuất đơn giản và hiệu quả về chi phí.

Từ xưa đến nay, rau luôn là thực phẩm cần thiết hàng ngày của con người, ông bà ta có nói câu: “Đói ăn rau, đau uống thuốc”. Hiện nay, các mặt hàng rau ở chợ hoặc các cửa hàng ngày càng đa dạng, phong phú; trong khi người bán càng phục vụ nhiều, sản lượng cao, người ta đã sử dụng nhiều phân bón hóa chất, thuốc bảo vệ thực vật (BVTV) nên chất lượng rau giảm, không đảm bảo an toàn. Ở vùng núi Tà Ngào, người ta ít trồng rau, một số dân tộc thiểu số đi vào rừng thu hoạch các sản phẩm trong rừng, hái cây cỏ nên đã khiến cho các giống loài càng ngày càng bị mất, thực vật không còn nhiều, hoang sơ. Do đó, chúng tôi phân tích đất, nước, nghiên cứu các điều kiện về nông hóa – thổ nhưỡng để trồng rau sạch, chăm sóc, bón phân, tưới nước (ở đây trồng củ cải, cải xanh, cải bẹ trắng và cải ngọt…), hạn chế tối đa việc dùng hóa chất như: không dùng thuốc trừ sâu rầy, thuốc diệt cỏ, không dùng phân hóa học mà chỉ sử dụng phân hữu cơ, tro trấu, các thực vật và sò ốc, rong…để phục vụ nhân dân. Vùng nghiên cứu là xã Lộc Thành, huyện Bảo Lâm, tỉnh Lâm Đồng.

This investigation aimed to evaluate the antibiotic susceptibility profiles of Salmonella species and Escherichia coli isolated from 100 garden egg samples obtained from diverse vendors in Abakaliki. Samples were transported to the Department of Applied Microbiology Laboratory, Ebonyi State University, Abakaliki, for analysis. Organisms were isolated and identified using standard microbiological techniques, while their antibiotic susceptibility was assessed through the disc diffusion method. Results indicated a prevalence of 60% for Salmonella species and 80% for E. coli among the analyzed samples. The antibiotic susceptibility testing unveiled alarming resistance patterns: Salmonella species displayed complete resistance (100%) to meropenem, perfloxacin, colistin, aztreonam, neomycin, gentamycin, ciprofloxacin, chloramphenicol, and ofloxacin, with only 16.67% susceptibility to streptomycin. Similarly, E. coli isolates exhibited 87.5% susceptibility solely to ofloxacin and 12.5% to chloramphenicol, while showcasing absolute resistance (100%) to other antibiotics tested. This study underscores the role of garden egg sales and consumption in facilitating the widespread dissemination of multi-drug resistant bacterial pathogens within the region. It emphasizes the urgent need for stringent adherence to hygienic practices among garden egg and other fruit vendors as a crucial preventive measure to curb this escalating threat. Keywords: Garden eggs, Salmonella species, E. coli, antibiotic resistance
NASA’s Support for Commercial LEO Destinations

Published: December 2023

The International Space Station (ISS) is planned to be operated through 2030. To ensure a sustained US presence in low-Earth orbit (LEO) beyond the ISS end of life, NASA is enabling the development of safe, reliable, and cost-effective commercial LEO destinations that the private sector will own and operate. The goal is for NASA to meet its research and technology needs as a customer, not an operator, of these destinations and to be one of many customers. The primary purpose of NASA’s Commercial LEO Destinations (CLD) project is to stimulate US private industry development of free-flying orbital destination capabilities and create a market environment in which CLD services are available to both Government and private-sector customers. NASA is using a two-phase strategy to achieve this purpose: • Phase 1 – A period of formulation and design by private industry, in coordination with NASA, of CLD capabilities determined to be most suitable for potential Government and private-sector customer needs. • Phase 2 – A competitive procurement by NASA of services in LEO which would include certification by NASA of the transportation and accommodations of NASA crew and payloads on CLDs. Four companies are developing CLDs, in partnership with NASA — one under contract and three under Funded Space Act Agreements. This paper will describe the role that NASA is playing to encourage development of CLD services in LEO and development of demand for those services.
A Dirigible Heliostatic Solar Concentrator Array for Martian Industrial Applications
Authors: Baldock Philip
Published: December 2023

A spherical inflatable solar concentrator is proposed for use on the Martian surface with potential for high mobility and convenient sun tracking as well as high peak temperatures. A rover inside the inflatable concentrator is able, by moving along the floor, to cause the structure to roll such that the interior concentrator mirror can be aligned with the sun (sun tracking) over the course of the Martian day. Comparison is made to conventional solid mirror heliostats suggesting the investigated approach may offer significant advantages in flexibility as well as lower system mass and size. Applications for early stage processes well suited to the proposal are suggested, its strengths being in processes requiring high power consumption and maintenance of elevated temperatures for sustained periods, such as carbochlorination, zeolite manufacture and pneumatic gas heating. Presently unsolved issues are then examined and future directions for research suggested.
Rethinking Mackinder’s Thoughts: The ‟Heartland” in the 21st Century Geopolitics

Published: December 2023

The concept of political science, political philosophy and geopolitics of classical war has been reevaluated or restructured from the 19th century to the 21st century. How applicable, implementable, and adaptable is Halford John Mackinder’s “Heartland” theory in resolving modern and premodern geopolitical conflicts? How can Mackinder’s thoughts be interpreted in modern political science and geopolitics today? These questions form the core of my study.
A célszerű jogértelmezésről és határairól
Authors: Tahin Szabolcs
Published: December 2023

A jogalkotó a jogrendünket 2020. április 1-től a korlátozott precedensrendszerbe sorolta. E „névváltoztatás” gyakorlati hatásait még csak részben ismerjük, de egy bizonyos: a bírói jogértelmezés kérdéseire nagyobb figyelmet kell fordítanunk. A Kúria eseti döntéseinek kötőereje arra ösztönözi a jogelméleti kutatásokat, hogy olyan értelmezéselméleti kérdéseket tegyünk fel, amellyel - legalább részben - leírhatjuk a bírói jogértelmezés határait.

A bírói jogértelmezést érintően a jogrendünket azonban egy másik lényeges változás is érte, az Alaptörvény a rendes bíróságok számára új értelmezői attitűdöt írt elő. A 28. cikk a korábbi szövegelvű jogértelmezés helyett a bíróságok számára a teleológiai jogértelmezés követését írta elő. Az ehhez igazodó „célszerű” jogértelmezés mibenléte azonban korántsem problémamentes jelenség. A tanulmány a célszerű jogértelmezés két arcát kívánja bemutatni: a célelvű és az észszerű jogértelmezést. Ezen értelmezési kánonok működésének leírására számos gyakorlati példát mutat be külföldi és hazai eseti döntések felsorakoztatásával.
