Penelitian ini dilaksanakan pada tanggal 24 Desember 2023 sampai dengan 28 Desember 2023 dengan tujuan untuk mempelajari perkembangan ejaan bahasa Indonesia pada masyarakat Sumbawa. Informasi  dan observasi dianalisis secara interaktif dan dieksplorasi secara rinci untuk memberikan kejelasan. Analisis dilakukan dengan cara mengorganisasikan dan mendeskripsikan satuan-satuan, mengintegrasikan dan mengorganisasikan ke dalam pola-pola, memilih apa yang penting dan apa yang akan dipelajari, serta menarik kesimpulan. Sejak masa penjajahan Belanda hingga saat ini, perkembangan Ejaan Bahasa Indonesia telah mengalami perubahan. Meski perubahan ejaan tersebut diterima oleh sebagian masyarakat, sebagian masyarakat lainnya mengatakan akan sulit beradaptasi dengan ejaan baru tersebut karena masyarakat sudah mengetahui bahasa Indonesia yang  dipengaruhi oleh bahasa daerah. Faktor-faktor yang menyebabkan kesalahan penggunaan Ejaan Bahasa Indonesia antara lain kesalahan  ejaan yang terus-menerus, kurangnya kompetensi Ejaan Bahasa Indonesia (EBI), dan kurangnya contoh penulisan kalimat yang sesuai dengan Ejaan Bahasa Indonesia (EBI).

The purpose of this study is to determine how the PAI curriculum is developed in pesantren, madrasah, and schools in the millennial era. This study uses a qualitative approach with a library research approach. The research results show that the curriculum is an essential component of the education program because it functions as a system and as a tool to achieve educational goals. In curriculum development, it must be adjusted to the conditions of students, schools, and the surrounding socio-cultural community, other parties related to the school. That is relevant to the needs and characteristics of the millennial generation will help them become individuals who are faithful, pious, and have noble character, which can be developed through intracurricular and extracurricular activities. Madrasah and pesantren prioritize in-depth Islamic education, while schools focus on general education in their curriculum development.

Published: July 2024

For over two decades, North West has been embroiled in tension and insecurity. It has been hot bed of banditry, cattle rustling, killing and kidnapping. Road users and farmers are kidnapped, slaughtered and burnt daily. Some say the challenge has degenerated as a result of the influx of criminals into the country. The existential threat posed by rural banditry in the North West, Nigeria has left many in doubt about the capacity of the Nigerian State to perform its constitutional responsibility of providing security for lives and property. The impression is that the State has become overwhelmed by the activities of armed bandits and has lost grip over their activities. Therefore, this paper seeks to explain how cultural affinity between Nigeria and her neighboring States induce insecurity in the region. This study is anchored on routine activity theory and argued that cultural homogeneity between Nigeria and her neighbors induce rural banditry in North West, Nigeria. The study relied on secondary data whereby data were gleaned from books, newspapers, and government official documents among others. The data were analyzed using content analysis. The finding revealed that cultural affinity between Nigeria and her neighboring States induce banditry in North West, Nigeria. We recommend stringent migration laws that would take records of every entry and exit of migrants in order to checkmate criminals who would leverage on the porous borders to perpetrate heinous crime in the country.

Published: July 2024

Qazma məhlullarının düzgün seçilməsi qazma əməliyyatlarının müvəffəqiyyəti üçün çox vacibdir. Reoloji parametrlərin tənzimlənməsi qazma məhlulunun effektivliyində əsas rol oynayır. Buna görə də, bentonit tərkibli su əsaslı qazma məhlulunun reoloji xüsusiyyətlərinin öyrənilməsi vacibdir. Bu tədqiqatın əsas məqsədləri bentonit tərkibli su əsaslı qazma məhlulunun reoloji və filtrasiya xüsusiyyətlərinə pH dəyişikliklərinin təsirini araşdırmaq, təhlükəsiz və yüksək məhsuldarlı qazma əməliyyatı əldə etmək məqsədilə qazma məhlulu üçün tövsiyə olunan pH diapazonunu təyin etməkdir. Müxtəlif pH dəyərlərinə malik bentonit tərkibli su əsaslı qazma məhlulunun fərqli nümunələri hazırlanmış və plastik özlülük, axıcılıq həddi və statik sürtünmə gərginliyi kimi reoloji xassələri ölçülmüşdür. Bundan sonra filtrasiya testi 20 atm differensial təzyiq və 80 °C temperatur altında aparıldı. Bentonit tərkibli su əsaslı qazma məhlulu üçün qələvilik məhlul reologiyasına əhəmiyyətli dərəcədə təsir göstərir. Sürüşmə sürtünmə gərginliyi və kəsilmə sürəti nisbəti pH-ın dəyişməsi ilə dəyişir. Praktiki olaraq pH-ın 8-dən 12-yə yüksəldilməsi plastik özlülüyünün müvafiq olaraq 53% və axıcılıq həddinin 82% azalması ilə nəticələnmişdir. Axıcılıq həddi/plastik özlülüyün nisbəti Ph=8 üçün 1,4 olmuşdur, pH=11 və pH=12 üçün isə o, 0,5-ə qədər düşmüşdür. Qələvilik artırıldıqda, statik sürtünmə gərginliyi göstəricilərində əhəmiyyətli azalma olmuşdur. Filtratın həcmi və gil qabığının qalınlığı pH artması ilə artmışdır. Filtratın həcmi pH-ı 9-dan 12-yə yüksəltməklə, 9,5 sm3-dən 12,6 sm3-ə yüksəldi. Gil qabığının qalınlığı Ph=9 -da 2 mm, Ph=12 üçün isə 3,6 mm-ə qədər artdı.
Nəticələrə əsasən, optimal olaraq məhlulun reoloji və filtrasiya xassələrini təmin etməyk üçün bentonit tərkibli su əsaslı qazma məhlulunun pH-nın 9-10 aralığında saxlanması tövsiyə olunur. Bu tədqiqatın nəticələri göstərdi ki, pH-nın 9 ilə 10 aralığında saxlanması plastik özlülüyü azaldacaq, bu da qazma sürətini artırmağa və məhlulun səthə sirkulyasiyası üçün tələb olunan nasos təzyiqini azaltmağa kömək edəcəkdir. Bundan əlavə, filtratın həcminin azaldılması boruların differensial yapışmasının qarşısını alacaq və nazik gil qabığı yaradacaq. Ümumiyyətlə, bentonit tərkibli su əsaslı qazma məhlulunun pH-nın 9-dan 10-a qədər optimallaşdırılması qazma əməliyyatını yaxşılaşdıracaq və ümumi məhlul itkilərini minimuma endirəcəkdir.

Published: July 2024

The study areas are located in the south-west of Absheron oil-gas-bearing region. The main oil and gas resources in this region are associated with Productive series sediments of Lower Pliocene system. The comparison of sediments and lithofacies of the Lower Productive series have been studied within Bibiheybat, Bahar, Gum-deniz areas of the South Absheron zone in the article.
The thickness of PS sediments is thiker in the study area. Lithologically, the Productive series sediments are represented by the alternation of sandy-aleourolite-clayey rocks.
Lower Pliocene sediments have undergone significant changes in their lithofacies, both at depth and along area. An increase in sand content is observed in the PS section from west to east in the Absheron oil-gas-bearing region.The variation of thicknesses, sand and clay content in Bibiheybat, Gum-deniz and Bahar fields was determined.
The changes in reservoir characteristics of PS suites in Bibiheybat, Gum-deniz and Bahar fields were analyzed. The analysis of porosity, permeability and carbonate in the studied areas of the PS suites suggests that in the Bibiheybat area, a regularity between carbonate and porosity and permeability is followed at depth towards the Pre-Kirmaki suite, so, carbonate decreases, porosity and permeability increases. However, the against regulation is observed in GaS, so carbonate increases, porosity and permeability decrease. Along the Gum-deniz area, porosity and permeability decrease with the increase of carbonate towards the GaS. In the Bahar field, the decrease of carbonate toward GaS, on the conrtary, the increasing of porosity and permeability is observed.
The comparative analysis of the reservoir properties along the fields suggest that the suites of the PS from the Bahar field to the Bibiheybat field are characterized by high reservoir properties. This is suggesting the prospect of oil-gas-bearing of lower suites of PS.
Keywords: Bibiheybat field, Productive series, oil-bearing, lithology, porosity, permeability, carbonate, sandiness, clayey.

Influence of the Height Value of Cylindrical Specimens of Copper Grade M3 on the Kinetics of Their Cooling and Heat Transfer Processes
Authors: Nizomov Z. , Sodatdinov S. , Saidzoda R. Kh. , Nematov D.
Published: July 2024

The paper presents the results of the influence of height values on the kinetics of their cooling and heat transfer processes of cylindrical samples made of copper M3 grade with a diameter of 1.0 cm. Characteristic cooling times for these processes are calculated. It is found that the characteristic cooling time increases in the series of radiation, heat conduction, and convection, linearly depending on the ratio of the sample volume to its surface area. Using experimental data on the cooling rate of the samples and theoretically calculated values of heat capacity by the Neumann-Kopp rule, the heat transfer coefficients for the processes of convection, heat conduction, and radiation as a function of temperature are estimated. It was found that with increasing temperature, the coefficients of radiative and conductive heat transfer increase, while the convective heat transfer coefficient decreases. A comparison of the heat transfer coefficients shows that within the experimental error, they do not depend on the sample length.

Published: July 2024

This paper presents the design and implementation of a solar charge controller system (SCCS) for emergencies in health facilities located in rural areas of Uganda. The SCCS is a Direct Current (DC) voltage regulator and controller that controls the production of power from solar panels and stores the power in battery backup systems. The charge controller reduces the voltage to prevent overcharging of the battery, which reduces its life expectancy. The SCCS also prevents the batteries from over-discharging, protecting the system from electrical overloading. The methodology utilized in this study is clearly outlined, detailing the design and implementation process of the SCCS. The experimental setup and testing show that the SCCS works accurately and low sunlight does not affect its efficiency. The SCCS efficiently protects the system from excessive current flow due to overloading and overvoltage. The average efficiency of the designed renewable energy system is 96.52% over eight days of testing. The SCCS presented in this paper is a cost-effective solution for emergencies in health facilities located in rural areas of Uganda, where access to electricity is limited.

Published: July 2024

Ultisol is a type of soil that is not very fertile but is commonly used for agriculture. The research aimed to gather information about how the application of rice husk biochar and cow manure, either separately or combined, would affect soil phosphorus levels, the uptake of phosphorus by spring corn plants (Zea mays saccaratha L.), and the weight of the plants when they are wet and when they are dried. The study used a 4x3 Factorial Randomized Block Design, with four levels of biochar and three levels of cow manure, followed by an analysis of variance. The research location is situated at an altitude of around 33 meters above sea level (masl) with soil acidity (pH) ranging from 5.5 to 6.5, and characterized by Ultisol soil type. The parameters observed included soil phosphorus levels, phosphorus uptake by plant stems and leaves, wet weight and oven-dried weight of plant stems and leaves, and wet weight of harvested cobs. The results of the study showed that applying rice husk biochar and manure as single treatments did not have a significant effect on increasing soil phosphorus availability, plant phosphorus uptake, wet weight and dry weight of plant stems and leaves, or baby corn production. However, there was a tendency for each observation parameter to show some improvement
Novel insights into autophagy in gastrointestinal pathologies, mechanisms in metabolic dysfunction-associated fatty liver disease and acute liver failure
Authors: Velikova Tsvetelina , Gulinac Milena
Published: July 2024

In this editorial, we comment on three articles published in a recent issue of World Journal of Gastroenterology . There is a pressing need for new research on autophagy's role in gastrointestinal (GI) disorders, and also novel insights into some liver conditions, such as metabolic dysfunction-associated fatty liver disease (MAFLD) and acute liver failure (ALF). Despite advancements, understanding autophagy's intricate mechanisms and implications in these diseases remains incomplete. Moreover, MAFLD's pathogenesis, encompassing hepatic steatosis and metabolic dysregulation, require further elucidation. Similarly, the mechanisms underlying ALF, a severe hepatic dysfunction, are poorly understood. Innovative studies exploring the interplay between autophagy and GI disorders, as well as defined mechanisms of MAFLD and ALF, are crucial for identifying therapeutic targets and enhancing diagnostic and treatment strategies to mitigate the global burden of these diseases.

Published: July 2024

Background: Acute pesticide poisoning is a global health concern, with organophosphorus compounds contributing significantly. Neonicotinoids, like imidacloprid, have emerged as alternative insecticides due to their selective action on pest nervous systems. This case report explores imidacloprid poisoning, emphasizing clinical manifestations and the ongoing search for safer pesticides.
Methods: A 46-year-old male, chronic smoker, and alcoholic, presented with suicidal imidacloprid poisoning. The patient experienced seizures, central nervous system (CNS) depression, hyponatremia, and respiratory arrest, necessitating mechanical ventilation. The case details the comprehensive evaluation, including imaging studies, and presents vital signs, laboratory results, and physical examinations. The patient received supportive care, and the discussion outlines the treatment strategy, highlighting the challenges and successes in managing imidacloprid toxicity.
Conclusion: This case underscores the complexity of imidacloprid poisoning, particularly noting convulsions secondary to hyponatremia. It stresses the need for further research into imidacloprid's metabolic effects and advocates for vigilant monitoring and supportive care in such cases. The report calls for increased reporting to enhance understanding and knowledge sharing regarding the potential toxic effects of imidacloprid, contributing to better management strategies for pesticide poisoning.
Non-symbolic estimation of big and small ratios with accurate and noisy feedback
Authors: Morton Nicola J. , Grice Matt , Kemp Simon , Grace Randolph C.
Published: July 2024

The ratio of two magnitudes can take one of two values depending on the order they are operated on: a ‘big’ ratio of the larger to smaller magnitude, or a ‘small’ ratio of the smaller to larger. Although big and small ratio scales have different metric properties and carry divergent predictions for perceptual comparison tasks, no psychophysical studies have directly compared them. Two experiments are reported in which subjects implicitly learned to compare pairs of brightnesses and line lengths by non-symbolic feedback based on the scaled big ratio, small ratio or difference of the magnitudes presented. Results of Experiment 1 showed all three operations were learned quickly and estimated with a high degree of accuracy that did not significantly differ across groups or between intensive and extensive modalities, though regressions on individual data suggested an overall predisposition towards differences. Experiment 2 tested whether subjects learned to estimate the operation trained or to associate stimulus pairs with correct responses. For each operation, Gaussian noise was added to the feedback that was constant for repetitions of each pair. For all subjects, coefficients for the added noise component were negative when entered in a regression model alongside the trained differences or ratios, and were statistically significant in 80% of individual cases. Thus, subjects learned to estimate the comparative operations and effectively ignored or suppressed the added noise. These results suggest the perceptual system is highly flexible in its capacity for non-symbolic computation, which may reflect a deeper connection between perceptual structure and mathematics.

Published: July 2024

The efficacy of direct mechanical thrombectomy (MT) and thrombectomy combined with intravenous thrombolysis (MT+IVT) in patients with acute ischemic stroke is still unclear. To comprehensively analyze the two strategies, we conducted a meta-analysis of randomized controlled trials (RCTs). Six RCTs were recruited from Ovid Medline, Embase, and Cochrane Central Register of Controlled Trials and published from 2020 to 2023, including 1164 in the MT group and 1170 in the MT + IVT group. There was no significant difference between the MT group and MT+IVT group in 90-day favorable outcome (OR 0.93, 95% CI 0.79-1.09, P=0.37, I2=0%,) and excellent outcome (OR 0.98, 95% CI 0.82-1.18, P=0.82, I2=0%). Similarly, there was no significant difference in 90-day mortality (OR 1.08, 95% CI 0.86-1.35, P=0.52, I2=0%) and symptomatic intracranial hemorrhage (OR 0.82, 95% CI 0.57-1.19, P=0.30, I2=0%). However, the successful recanalization rate of the MT group was significantly lower than that of the MT+IVT group (OR 0.73, 95% CI 0.57-0.94, P=0.01, I2=0%). There was no significant difference in functional outcome and safety endpoints between direct MT and MT+IVT, but the successful recanalization rate of MT+IVT was higher.

Published: July 2024

This study comprehensively compares various low-cost mineral and industrial waste adsorbents in the Adsorbent Pervious Concrete (APC) mixture, focusing on their engineering properties and environmental aspects. Fine-grained adsorbents, including anthracite, iron slag, lignite, LECA, perlite, pumice, and zeolite, were added at a proportion of 10% by weight of coarse aggregate (0.6-1.2 mm size range). Compressive strength, porosity, and permeability tests were conducted to assess APC's engineering properties, while its efficiency in reducing Chemical Oxygen Demand (COD) and Total Suspended Solids (TSS) in urban runoff was examined. ANOVA analysis was performed to evaluate the impact of different adsorbents on APC performance. Results showed that the specific gravity of the adsorbents significantly influenced APC's compressive strength. Anthracite, iron slag, and zeolite increased compressive strength, while all adsorbents, except zeolite, reduced porosity and permeability. Lignite-containing APC exhibited the lowest compressive strength, porosity, and permeability with reductions of 16.12%, 24.7%, and 21.07%, respectively. Furthermore, APC samples demonstrated improved urban runoff quality, with zeolite exhibiting the best performance by reducing COD and TSS by 50.1% and 45.79%, respectively. ANOVA analysis confirmed the substantial influence of different adsorbents on APC's mechanical, physical, and environmental properties. Based on affordability, zeolite, iron slag, and pumice are recommended for use in APC mixtures, offering potential applications in urban areas and building landscaping. This critical analysis provides valuable insights for developing sustainable stormwater management with APC while enhancing its mechanical properties. Further research is encouraged to optimize the selection and utilization of adsorbent materials in APC system.

Published: July 2024

The Conjugate Gradient (CG) method stands as an evolved computational technique designed for addressing unconstrained optimization problems. Its attractiveness stems from its simplicity, making it straightforward to implement, and its proven track record in effectively addressing real-world applications. Despite the recent surge in interest in this field, certain newer versions of the CG algorithm have failed to outperform the efficiency of their predecessors. Consequently, this paper introduces a fresh CG variant that upholds essential properties of the original CG methods, including sufficient descent and global convergence. In this paper, three types of new CG coefficients are presented with applications in optimizing data. Numerical experiments show that the proposed methods have succeeded in solving problems under exact line search conditions.

Authors: Ali Bahr Ennil  , Abdulhafid M A Elfaghi
Published: July 2024

The turbine blade is designed to achieve expansion at high efficiency levels. For improving the turbine efficiency, different aerodynamic design optimisations are performed. On the other hand, the aerodynamic design must be enhanced to match the mechanical design. This research proposes a novel design optimisation method for both aerodynamic and mechanical requirements. A multidisciplinary optimisation approach is used to improve the reliability of the turbine design, which included the use of Computational Fluid Dynamics (CFD) models and Finite Element Analysis (FEA). The primary objective is to guarantee that the aerodynamically optimised blade profile could efficiently withstand mechanical stress. The multidisciplinary optimisation approach is successful in reducing total equivalent pressures from 49.72 MPa to 41.73 MPa while keeping the turbine's overall efficiency at an impressive level of 80.95%. These Results highlight the effectiveness of using a multidisciplinary optimization method to successfully improve the efficiency of a turbine blade profile while simultaneously ensuring its ability to withstand the needed mechanical loads. Using a multidisciplinary optimisation method, the turbine maintains an impressively high efficiency of approximately 83%, with only a marginal reduction of 1.8% compared to the efficiency achieved solely through aerodynamic blade optimisation.

The polyvinyl alcohol (PVA) solution and Gd2O3 powder were combined and the combination was then sonicated for around 6 hours. A micro-film was created by allowing the solution to dry out over the period of 48 hours. The Gd2O3-SA was inserted into an EDFL configuration to produce a steady passively Q-switched pulse train. This made it possible to adjust the pump power of the 980 nm pump to be between 24.58 and 76.75 mW. The operational wavelength of the laser was 1562.9 nm and the repetition rate increased rapidly from 51.9 to 77.1 kHz.
