Ecological restoration in arid and semi-arid ecosystems faces complex challengesdue to water scarcity, extreme temperatures, degraded soils, and biotic interactionssuch as livestock grazing and the high presence of exotic plant species.Reforestation, as an active restoration technique, aims to recover these ecosystemsthrough the planting of native species. However, these projects are costly andrequire significant intervention. Eight restoration initiatives in the tamaulipanthornscrub (TTS) of Nuevo León, Mexico, were reviewed, with results publishedbetween 2016 and 2024. These projects were implemented on land altered by ahistory of agricultural and livestock use. Restoration actions includedsupplementary irrigation and the removal of exotic vegetation. Native plantspecies extracted or rescued from the wild, as well as plants developed innurseries, were used for planting. A total of 33 plant species were used in thereviewed initiatives, with Cordia boissieri A. DC. being the only species commonto all. Planting designs included "tres bolillo" and "marco real" systems withvarying densities. Survival rates fluctuated with plantation monitoring, beinglower as time increased and maintenance decreased.

Published: January 2025

Forecasting Premium Motor Spirit (PMS) prices accurately is crucial for economic stability and effective decision-making in Nigeria. Premium Motor Spirit (PMS), which is also known as petrol or fuel, plays a pivotal role in the country's economy, impacting transportation costs, inflation rates, and overall economic growth. However, the unpredictability of PMS prices prediction and management is influenced by factors like government policies, international oil markets, supply chain disruptions, stakeholders and interested cartels amongst others. This has created a constant price fluctuation, poor price control and management which eventually lead to fuel scarcity and high cost of fuel. The price control mechanism remains a contentious issue, with debates over its impact on the economy, government spending, and the welfare of ordinary Nigerians. This article presents an enhanced model for Premium Motor Spirit (PMS) price prediction and management in Nigeria using machine learning that will improve the price prediction and management system that will produce high degree of accuracy. The system was developed using visual studio C#, ML.Net model and Microsoft SQL server for its backend database. This model identifies key factors impacting PMS prices prediction and management that is used to forecast PMS prices over a specified time horizon such as daily, weekly, or monthly thereby enhancing economic planning and stability in Nigeria.

Authors: Ogbolumani Omolola A. , Godfrey Daniel
Published: January 2025

The exponential growth in urban population has intensified the challenges of municipal waste management, necessitating innovative technological solutions. This research presents an integrated approach to developing a smart waste management system by integrating wireframes, 3D modeling, and simulation technologies. The study employs a three-phase methodology: utilizing wireframe prototyping for user interface design, enabling iterative development based on stakeholder feedback, implementing detailed 3D modeling of smart waste bins to visualize and optimize waste flow dynamics, and conducting comprehensive simulations to evaluate system performance under various scenarios. The simulation analysis compared multiple routing algorithms while monitoring real-time bin capacity through virtual sensors. Results demonstrate a 25% improvement in collection efficiency using dynamic routing compared to traditional fixed routes and a 30% reduction in overflow incidents through predictive capacity monitoring. The user-centered design approach, validated through wireframe testing with 50 participants, showed a 40% increase in system engagement compared to conventional waste management interfaces. Additionally, the 3D modeling phase identified critical design modifications that improved bin accessibility by 35% and reduced maintenance requirements by 20%. This research contributes to the growing knowledge of smart city solutions while providing practical insights for municipalities seeking to modernize their waste management. infrastructure. The proposed system offers a scalable, efficient approach to addressing urban waste challenges while promoting environmental sustainability. A limitation of the study is its reliance on simulation-based testing, which may not fully represent real-world operational complexities. A major challenge is implementation dependency on continuous stakeholder engagement and high reliance on technological infrastructures.

Background: Acute Kidney Injury (AKI) is independently associated with worsened morbidity and increased mortality in critically ill children in the Pediatric Intensive Care Unit (PICU). Till date Serum Creatinine (S.Cr) is the gold standard for AKI detection. Urinary Neutrophil Gelatinase-Associated Lipocalin (uNGAL) is revealed as a promising novel biomarker for the early detection of kidney damage. The study is aimed to evaluate the ability of uNGAL for early detection of severe AKI in critically ill children. Materials and methods: This prospective observational study included 90 pediatric ICU (PICU) patients aged 1 month to 12 years from December 2020 to November 2021.Urine was collected for uNGAL on admission (Day 0). Blood samples were collected on Day 0 (D0), Day 3 (D3) and Day 7 (D7) for serum creatinine (S.Cr). AKI was defined and staged according to Kidney Disease Improving Global Outcomes 2012 criteria. Results: Among 90 children, 26 (28.9%) develop severe AKI on D3. The median uNGAL level was 182.9 ng/ml in children with severe AKI compared to 44.3 ng/ml in those without severe AKI. The AUC for the D0 uNGALto predict D3 severe AKI was 0.945 (CI 0.867–1.0). The best cutoff point for uNGAL was 102.70 ng/ml, with a sensitivity of 96.15% and specificity of 98.44% for D3 severe AKI. D0uNGAL had no significant correlation with D0S. Crbut had a significant positive correlation with D3 and D7 S.Cr. Conclusion: Urinary NGAL is an useful early AKI marker to detect the development of severe AKI in critically ill children of PICU.

Background: Oral health is an integral part of our overall health and well-being but it is regularly ignored in the healthcare delivery system in Bangladesh. A few significant factors are the general public's lack of awareness and the shortage of infrastructure and resources like dentists and specialists. Due to the COVID-19 pandemic, the condition is more critical. Many countries are practicing Teledentistry (Smartphone- based digital platform) services which could be an alternative for Oral Health Care Management in Bangladesh both for the urban and rural people. So, the aim of this study was to assess the attitude and interest of dentists and dental patients in Bangladesh towards Teledentistry which is a technology-based digital platform for oral health care management. Materials and methods: This cross-sectional study was conducted during the period from July - December 2021 using a pretested semi-structured questionnaire for dental patients. An online questionnaire was sent to 300 participants of both rural and urban people of Bangladesh and 206 responded. The response rate was 68%. For dentists we used a qualitative approach, we conducted a focus group discussion at Dhaka Dental College Hospital among a group of dentists. Results: The findings of this study showed that 82.7% of dental patients were highly interested in teledentistry for use in the future if available in our country and 74.3% of them were not satisfied with present oral and dental service-taking procedures. At the same time, the majority of the dentists showed a positive attitude and interest towards Teledentistry service in Bangladesh and they expressed that it will be an amazing initiative for our country which is the need of time now. Conclusion: So, the findings of this study assessed the attitudes and interests of dentists and dental patients which will help in the future development of smartphone phone-based teledentistry platform in Bangladesh.

АКУСТИЧНІ ПОЛЯ НИЗЬКОЧАСТОТНИХ ЕЛІПТИЧНИХ ВИПРОМІНЮВАЧІВ ПОЗДОВЖНЬО-ЗГИННОГО ТИПУ В ГІДРОАКУСТИЧНИХ НАВІГАЦІЙНИХ СИСТЕМАХ

Пріоритетним напрямком розвитку гідроакустичних навігаційних систем і засобів підводного спостереження є низькочастотна активна гідролокація. Практична реалізація тенденції зниження робочих частот гідроакустичних станцій потребує пошуку нових електромеханічних коливальних систем, які мали б низькі частоти механічного резонансу і одночасно малі розміри та масу. В якості однієї з таких систем запропоновано еліптичний перетворювач поздовжньо-згинного типу. Він поєднує в собі поздовжні коливання п’єзокерамічного стрижня та згинні коливання металевої еліптичної оболонки, жорстко з’єднаної з торцями стрижня. Встановлено, що поздовжньо-згинний випромінювач має дві особливості. Перша полягає в тому, що в поперечному перерізі поздовжньо-згинний випромінювач має відносно малі розміри, завдяки чому вони є малими порівняно з довжиною робочої хвилі випромінювача. Друга особливість пов’язана з тим, що коливання випромінюючої поверхні випромінювача є неоднорідними. Оскільки коливання еліптичної оболонки є згинними, це обумовлює появу на окремих її ділянках, які прилягають до великої осі еліпсу, протифазних коливань порівняно з іншими ділянками оболонки. Запропонована схема побудови еліптичного поздовжньо-згинного перетворювача. Наведена його фізична модель, яка складається із активного п’єзокерамічного елементу стрижньового типу, що здійснює поздовжні коливання, та металевої еліптичної оболонки, яка перетворює ці поздовжні коливання в згинні коливання оболонки. Розроблена розрахункова модель поздовжньо-згинного випромінювача і на її основі в еліптичній системі координат з використанням кутових і радіальних функцій Матьє розв’язане рівняння Гельмгольца відносно потенціалу швидкості акустичного поля. На основі отриманих співвідношень для акустичного поля визначені направлені властивості поздовжньо-згинного випромінювача.
Ключові слова: поздовжньо-згинний перетворювач, п’єзокерамічний елемент стрижньового типу, направлені властивості.
