Two‐Layer Optimal Electricity Trading Method for Distribution Networks with Multi‐MG

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
To enhance the operational benefits of distribution networks and microgrids while reducing microgrid energy costs, this paper proposes a distributed trading strategy for microgrids based on a leader–follower game. First, a multi‐objective two‐layer optimization trading model for distribution network (DN)‐microgrid (MG) interaction is established based ...

Analysis of Heavy Metal Pollution in the Water of the Halda River: A Distinctive Breeding Habitat for Carp Fish in Bangladesh

Veterinary Medicine and Science, Volume 10, Issue 6, November 2024.
Over the course of the study, heavy metals (Cr, Cu, Cd, Fe, Zn and Pb) were analysed using Flame atomic absorption spectrophotometer. The assessed mean concentrations of heavy metals follow the trend: Fe > Pb > Zn > Cr > Cu > Cd. A moderate seasonal variation was found among the sampling sites.

Pleiotropic phenotypic effects of the TaCYP78A family on multiple yield‐related traits in wheat

Plant Biotechnology Journal, Volume 22, Issue 10, Page 2694-2708, October 2024.
Summary Increasing crop yield depends on selecting and utilizing pleiotropic genes/alleles to improve multiple yield‐related traits (YRTs) during crop breeding. However, synergistic improvement of YRTs is challenging due to the trade‐offs between YRTs in breeding practices.

Evaluation of steady-state ground resistance by field measurement and CDEGS computation

Bulletin of Electrical Engineering and Informatics
In addition to the soil resistivity and size of the grounding system, grounding system configuration can influence the steady-state resistance (RDC) of a grounding system. The RDC of four to six configurations in three distinct soil conditions (sites 1 to 3) is measured using the fall-of-potential method and computed using the current distribution ...
