Experimental study of the influence of adhesive properties and bond length on the bond behaviour of NSM FRP bars in concrete

Journal of Civil Engineering and Management, 2016
The near-surface mounted (NSM) fibre reinforced polymer (FRP) technique is a relatively recent system for strengthening concrete structures. Bond is a key factor in its behaviour, and is affected by many factors whose influence can only be tested through

Elevated Spring Methane Emissions in a Sub‐Arctic Peatland Fen

Journal of Geophysical Research: Biogeosciences, Volume 131, Issue 8, August 2026.
Abstract The Arctic boreal region is rapidly shifting in response to global climate change, including rapid warming and permafrost thaw. Year‐round monitoring of carbon fluxes in these regions is crucial to understanding seasonal and annual carbon budgets, including methane (CH4), a potent greenhouse gas with 80 times the warming potential of carbon ...

Serviceability limit state of two-way reinforced concrete slab strengthened with different techniques

MATEC Web of Conferences, 2018
The experimental results for service load of sixteen simply supported two way reinforced concrete slabs under the action of concentrated patch load were determined based on the amount of permissible deflections and the crack widths.All the slabs had the ...

Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

Structural Concrete, Volume 27, Issue 3, Page 3018-3040, June 2026.
Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Experimental and numerical investigation of alternative CFRP systems combining sheets and ropes for shear-flexural strengthening of T-beams

Developments in the Built Environment
This study investigates hybrid shear-flexural strengthening strategies for reinforced-concrete T-beams using external reinforcement, i.e., carbon fiber-reinforced polymer (CFRP) sheets and closed-form near-surface-mounted (NSM) CFRP ropes.

Chromosome‐Level Genome and Organ‐Specific Transcriptome of Alnus glutinosa Uncover Lineage‐Specific Innovations in Root Nodule Symbiosis

Plant, Cell &Environment, Volume 49, Issue 6, Page 3003-3021, June 2026.
ABSTRACT Alnus glutinosa is one of only three lineages within the order Fagales capable of establishing root nodule symbiosis (RNS). Although a fragmented genome assembly of A. glutinosa was previously available, its limited quality, combined with the lack of comprehensive transcriptomic resources, has constrained in‐depth comparative and functional ...

G Protein–Coupled Receptors in Olfactory Signaling and Related Disorders: Mechanisms and Therapeutic Implications

Sensory Neuroscience, Volume 2, Issue 1, March 2026.
This schematic highlights GPCRs as the central hub of olfactory signaling in health and disease. The central GPCR shows odorant activation and downstream pathways. Surrounding quadrants illustrate four GPCR‐mediated themes: odor perception and adaptation, mucosal immunity and regeneration, memory consolidation via neural circuits, and GPCR‐related ...

Advancing urine‐derived stem cells: Cryopreservation validation and sex‐specific metabolism

European Journal of Clinical Investigation, Volume 56, Issue 1, January 2026.
Urine‐derived stem cells (UDSC) are a non‐invasive, easily accessible source of stem cells with robust differentiation potential. We developed a cryopreservation protocol for UDSC isolated from healthy donors, assessing viability, apoptosis/necrosis, metabolic profile and differentiation capacity.
