Modelling Climate Change Impact on Rice Growth and Yield in Northwest Bangladesh

Journal of Sustainable Agriculture and Environment, Volume 5, Issue 1, March 2026.
ABSTRACT Assessing the impact of climate change is crucial for addressing the challenges of sustaining and increasing rice production. This study employed the APSIM model driven by climate data from 27 global climate models under SSP245 and SSP585 emission scenarios to evaluate climate change effects on irrigated and rainfed rice in three key rice ...

River Ecosystem Degradation and Its Impacts on Fish Biodiversity and Capture Fisheries in Major River Basins of Bangladesh: A Policy‐Focused Study

Aquaculture, Fish and Fisheries, Volume 6, Issue 1, February 2026.
ABSTRACT This study investigates the widespread degradation of river ecosystems in Bangladesh and its impact on fish biodiversity and identifies potential strategies for ecosystem restoration. Combining community perceptions from focus group discussions (FGDs) with fish market study for spatial analyses of fish species diversity across the Barak–Meghna,

Herbariomics and the peculiar case of Alisma wahlenbergii (Alismataceae)

TAXON, Volume 75, Issue 1, Febuary 2026.
Abstract Species identification and delimitation in aquatic plants can be challenging due to their often simple, plastic, and convergent morphology. This has led to varying taxonomic opinions in many genera, including Alisma. One debated case is the narrowly endemic A. wahlenbergii, which occurs submerged in the Baltic Sea region.

Microstructure, mechanical, and thermal properties of compositionally complex (Hf,Zr,Nb,Ti)B2‒LaB6 ceramics

International Journal of Applied Ceramic Technology, Volume 23, Issue 1, February 2026.
Abstract Novel compositionally complex borides, (Hf,Zr,Nb,Ti)B2 and (Hf,Zr,Nb,Ti)B2‒LaB6, were fabricated using spark plasma sintering process. (Hf,Zr,Nb,Ti)B2‒LaB6 exhibits a dual‐phase microstructure, in which (Hf,Zr,Nb,Ti)B2 is a primary phase with the hexagonal structure and LaB6 is a secondary phase with a cubic structure.

Conceptual Modelling and The Quality of Ontologies: Endurantism Vs. Perdurantism

, 2012
Ontologies are key enablers for sharing precise and machine-understandable semantics among different applications and parties. Yet, for ontologies to meet these expectations, their quality must be of a good standard.

Phase Composition‐Controlled Synthesis, Microstructure, and Properties of TiB2–TiC Composite

International Journal of Ceramic Engineering &Science, Volume 8, Issue 1, January 2026.
TiB2–TiC composite powders were synthesized via the boron/carbon thermal reduction. A comprehensive investigation of the reaction mechanism was conducted, leading to the construction of a phase diagram that served as a guideline for formula development.
