| Correction of the Sabine Formula Using an Artificial Neural Network – A One-Solution Approach | ||||||
The first part of this paper presents the classical Sabine formula used for estimating the reverberation time (𝑇60
of a room. An experiment was then conducted in which the reverberation time was evaluated using both the
Sabine formula and the Schroeder algorithm, the latter estimating 𝑇60through the analysis of the Room Impulse
Response (RIR).The second part of the paper introduces a corrected Sabine formula obtained by multiplying the
original Sabine expression with a correction.....

| Above- and Below-Ground Carbon Stocks of Protected and Disturbed Mangrove Forests in Finima, Bonny Island, Nigeria | ||||||
Mangrove forests are among the most productive and carbon-rich ecosystems on Earth, providing essential services such as shoreline protection, nursery habitats for fisheries, nutrient cycling, and long-term carbon sequestration. However, degradation from deforestation, wood harvesting, and land conversion releases significant greenhouse gases. Assessing above-ground and below-ground biomass along disturbance gradients is therefore crucial for understanding how human activities affect the climate-mitigation capacity of mangroves, particularly in Nigeria's Niger Delta. This study quantified above-ground biomass.......... Above-ground biomass (AGB), Below-ground biomass (BGB), Soil organic carbon (SOC), Mangrove forests.

| In silico pharmacokinetic profiling of bioactive compounds from methanolic extracts of Paederia foetida Linn | ||||||
The Native plant Paederia foetida, sometimes known as the skunk vine, is a member of the Rubiaceae family. A wide range of conditions can be treated with the plant, including rheumatoid arthritis and liver diseases. The goal of the current study was to utilize Swiss ADME to determine the pharmacokinetic profile of the methanolic extract from Paederia foetida leaves. Several bioactive substances were identified using GC-MS analysis, with terpenoids, fatty acid esters, and aromatic derivatives showing the largest peaks. The absorption, distribution, metabolism, and excretion (ADME) characteristics of these substances were examined in detail.Only a small percentage exhibited pharmacokinetic limitations, whereas the majority met Lipinski's rule of five and demonstrated good gastrointestinal absorption, adequate solubility, and excellent drug likeness scores.

| Integrated Review and Classification of Remedies & Engineering Approaches for Nonlinearity Management in High-Speed Optical Networks | ||||||
The nonlinear impairments in high-speed optical communication networks are becoming more and more limited by Kerr effects, dispersion-nonlinearity interactions, and amplified spontaneous emission noise. With changes in the transmission systems toward terabit-scale data rates, operation in an ultrawideband and space-division multiplexing architecture, the ability to maintain nonlinearity is critical in maintaining reach, spectral efficiency, and energy performance. The given paper provides a synthesizing overview and categorization of key remedies such as optical phase conjugation, Raman/EDFA hybrid amplification, soliton-based transmission..........

| Smart and Resilient Cities: Designing for Climate, Technology, and Human Well-Being | ||||||
Cities around the world are increasingly challenged by the intersecting pressures of climate change, technological transformation, and rapid urbanization. Building resilience in this context requires an integrated approach that goes beyond infrastructure durability or digital innovation alone. This article examines how climate-responsive urban design, technological innovation, and human well-being can be combined to create smart and resilient cities. Drawing on multidisciplinary perspectives, it argues that resilience is most effective when ecological adaptation strategies are reinforced by robust digital systems and grounded in human-centered values..........

| Investigation of the Impact of Seawater on the Compressive Strength of Sandcrete Blocks: A Case Study of Nembe, Nigeria | ||||||
The durability and strength performance of construction materials in coastal environments are crucial for sustainable infrastructure. This study investigates the effect of seawater on the compressive strength of sandcrete blocks in Nembe, Bayelsa State, Nigeria. Sand and water samples were collected from Basambiri (seawater environment) and Amassoma (freshwater environment). Sandcrete blocks were produced using a cement-to-sand ratio of 1:8 and cured for 7, 14, 21, and 28 days with either freshwater or seawater. Compressive strength tests were conducted using a Universal Testing Machine in accordance with ASTM C140/C140M-20 and NIS 87:2000 standards..........
