Thermal Power and Climate Change: A Data-Driven Analysis of Cause and Effect, 1800-2100
Published: 2025-11-20
Subjects: Education, Engineering, Life Sciences, Physical Sciences and Mathematics, Social and Behavioral Sciences
Since 2020, global politics have shifted sharply to the right—nowhere more visibly than in Europe and the United States. By 2024, this rightward turn in the U.S. culminated in open climate-change denial, the defunding of clean-energy initiatives, and a widespread rejection of scientific evidence. Major domestic and international institutions—NOAA, NASA, the U.S. Weather Bureau, EPA, USDA, FDA, [...]
Developing an Open-access Telegram Bot for Automated, estimation and IA-based interpreted of OpenQuake Ground-Motion intensity measures
Published: 2025-11-13
Subjects: Education, Engineering, Life Sciences, Physical Sciences and Mathematics
The prediction of Intensity Measures (IMs) using Ground-Motion Models (GMMs) is a fundamental component of seismic hazard assessment. However, the best estimation of IMs traditionally requires specialised searchers, programming expertise, and the manual sourcing of regression coefficients. This complexity creates a significant barrier to rapid, scenario-based analysis for engineers, researchers, [...]

On radiocarbon near the epicenter of the 1908 Tunguska event
Published: 2025-10-23
Subjects: Education, Engineering, Physical Sciences and Mathematics
This paper is a continuation of a series of works, devoted to various aspects of the 1908 Tunguska event. A large number of hypotheses about its causes have already been put forward. However, so far none of them has received convincing evidence. Since the late 1950s, a large number of studies have been carried out in the area of the Tunguska event, including those related to radiocarbon [...]
The Perimeter of Conflict: Geospatial Vulnerability Assessment of Conservation Areas Under Dhaka's Detailed Area Plan (2022–2035)
Published: 2025-10-20
Subjects: Education
Dhaka’s unrelenting developmental pressure, managed under the strategic blueprint of the Detailed Area Plan (DAP) 2022–2035, has exposed a critical paradox: the policy commitment to environmental conservation is systematically undermined by rampant, quantifiable ecological encroachment. This comprehensive study utilizes advanced Geographic Information Systems (GIS) and a Multi-Criteria Decision [...]
Toward Greater Clarity: Reanalyzing Solomon’s Depiction of the Ross Ice Shelf Atmospheric Dynamic
Published: 2025-10-10
Subjects: Education, Physical Sciences and Mathematics, Social and Behavioral Sciences
In the final chapters of The Coldest March: Scott's Fatal Antarctic Expedition, Dr. Susan Solomon analyzes the meteorological conditions surrounding the last blizzard that claimed the lives of Captain Robert Falcon Scott, Dr. Edward Wilson, and Lieutenant Henry Bowers. The book’s conclusion—that the storm could not have lasted ten days and that the men may have chosen to die—warrants close [...]
Secondary Education Students’ Misconceptions on Principles of Geology: Minerals and Rocks
Published: 2025-09-06
Subjects: Education
The purpose of this research is to investigate the misconceptions related to geological concepts among Secondary Education students in the region of Achaia, Greece. The study focuses on both Lower Secondary Education (Gymnasium, grades 7–9) and Upper Secondary Education, including General and Vocational Education (grades 10–12). Previous research has shown that students entering Lower Secondary [...]
Band ratio to band difference for Chl of oceanic waters: broke a self-imposed no-touch zone
Published: 2025-08-28
Subjects: Education, Physical Sciences and Mathematics
There are many empirical algorithms developed for the remote sensing of chlorophyll-a concentration (Chl) from ocean color measurements, with the blue-green band-ratio type of algorithms dominating these practices. During the phase of algorithm development, which is data-driven, generally the errors of remote sensing reflectance (Rrs) from satellites are ignored until Hu et al. (2012) developed a [...]
Development of Low-Cost, Open-Source Unmanned Surface Vehicle for Water System Monitoring
Published: 2025-08-27
Subjects: Education, Engineering
Commercially available Unmanned Surface Vehicles (USVs) in the market are expensive, and the software used for automating navigation and bathymetry mapping are typically proprietary. Large scale collection of water quantity and quality data requires dynamic in-situ sensing approaches with open-source software for user flexibility. This manuscript presents an open-source, economic, and efficient [...]
Assessing the Economic and Environmental Benefits of Nature-Based Solutions for Sustainable Infrastructure. A Case of Kumasi, Ghana
Published: 2025-08-26
Subjects: Education
Kumasi, Ghana, and most rapidly developing cities in Sub-Saharan Africa are confronted with increasing environmental and infrastructure concerns as a result of rapid urbanization, inadequate land use planning, and climate change. Traditional grey infrastructure has been inadequate in mitigating these problems. This paper assessed the economic and environmental advantages of Nature-Based Solutions [...]
Virunga Volcanoes Supersite Biennial Report: 2017- 2019
Published: 2025-08-09
Subjects: Education, Engineering, Life Sciences, Physical Sciences and Mathematics
The Virunga Volcanoes is the first Supersite established on the African continent in a highly populated Multi-hazards region. This permanent Supersite was established in a critical context as little was known about the Virunga hazards sources and their dynamics, and little done as measures to evaluate, mitigate and reduce their impacts. Similarly, the active volcanoes are poorly studied and [...]
The 1908 Tunguska event and electromagnetic phenomena
Published: 2025-07-31
Subjects: Education, Physical Sciences and Mathematics
This paper is a continuation of a series of works, devoted to various aspects of the 1908 Tunguska event. In this paper its author would like to draw attention to the arguments about the manifestations of electromagnetic phenomena in the 1908 Tunguska event. A review is provided of some data supporting the idea about the manifestation of electromagnetic phenomena. Although there is no direct [...]
Quantum Entropy & Probabilistic Clustering for Uncertainty-Aware Groundwater Quality Assessment in Geochemically Complex Terrains of Eastern India
Published: 2025-07-25
Subjects: Education, Physical Sciences and Mathematics
Groundwater quality assessment in geochemically heterogeneous regions is often constrained by deterministic models that overlook spatial variability, inter-parameter dependencies, and system uncertainty. This study proposes a novel Quantum Entropy-based Groundwater Quality Index (QEGWI), which leverages von Neumann entropy derived from quantum density matrices to weight hydrogeochemical [...]
