Influence of mix design method on the shear capacity of reinforced concrete beams made with high‐quality recycled coarse aggregate

Structural Concrete, Volume 27, Issue 5, Page 8015-8044, October 2026.
Abstract This study investigates the shear capacity behavior of reinforced concrete (RC) beams without stirrups incorporating recycled coarse aggregate (RCA). An extensive database comprising 269 experimental data points from 40 journal articles published between 2001 and 2025 was compiled, excluding specimens with recycled fine aggregate or fiber ...

Power Quality Enhancement using DVR based on Ant colony Controller

, 2016
PI controller tuning is a difficult task under varying operating conditions. Optimal tuning of PI gains is required to get the best response of PI controllers. This paper presents the Dynamic Voltage Restorer (DVR) using ant colony optimization based PI

Sequence analysis based DSP controller for dynamic voltage restorer (DVR) [PDF]

, 2008
The paper examines the behaviour of a dynamic voltage restorer (DVR) under balanced/unbalanced supply voltage sag condition, and restricted DVR injection capability (e.g. limited to 50% of the supply voltage injection).

Punching shear of unbonded post‐tensioned steel fiber reinforced concrete slabs: The fiber contribution

Structural Concrete, Volume 27, Issue 5, Page 8045-8065, October 2026.
Abstract Steel fiber reinforced concrete (SFRC) enhances the flexural capacity of flat slabs and, due to its effectiveness in statically redundant bi‐dimensional elements, represents a viable alternative to conventional reinforcement. Although numerous studies have investigated the flexural behavior of SFRC slabs with and without bonded reinforcement ...

Remembering Interracial Intimacies: South Asian Perspectives on Black/Brown Sex and Romance in Colonial East Africa

Gender &History, Volume 38, Issue 3, Page 833-845, October 2026.
ABSTRACT Bringing together historical evidence, postcolonial fiction and memory work, this study recovers South Asian cultural attitudes towards interracial heterosexual romance from the margins of East African history. It asks why Black/brown intimacy was treated as taboo and denied legitimacy within South Asian diasporic communities in British‐ruled ...

Understanding the Immune Response Changes to Clinical Interventions for Epstein–Barr Virus Infection Prior to Lymphoma Development in Children After Organ Transplants (UNEARTH)

Pediatric Transplantation, Volume 30, Issue 10, October 2026.
The T cell and Natural Killer cell immune responses in primary EBV infection in children or during progression to PTLD are not well characterized. By performing detailed prospective immunological phenotyping through the first year after 278 pediatric organ transplants, we will unearth pathways that may inform EBV oncogenesis progression.
