Shear and punching capacity predictions for slabs under concentrated loads aided by lefea

, 2023
One-way slabs under concentrated loads may fail by one-way shear, punching, flexure or a mixed-mode between them. This study examines the benefits of using Linear Elastic Finite Element Analyses (LEFEA) combined with analytical expressions to predict the

Hydroxycinnamic Acid Amides Emerge as Multifunctional Molecules Involved in Regeneration and Volatile Signalling During Wound Responses

Plant, Cell &Environment, EarlyView.
ABSTRACT Hydroxycinnamic acid amides (HCAAs) are phenylpropanoid‐derived metabolites traditionally associated with antimicrobial defence and cell wall reinforcement during plant–pathogen interactions. However, their contribution to plant responses to mechanical injury, particularly in wound healing and damage‐induced signalling, remains poorly ...

Theory and technology of enhanced coal seam gas production by integrated drilling, punching and fracturing in coal mine: Part 1 theory

International Journal of Coal Science & Technology
Coal seams in China are typically characterized by high coal seam gas content and low permeability, posing challenges for efficient coal seam gas extraction. However, achieving successful boreholes, especially in soft coal formations, remains a challenge.

Reinforced concrete flat slabs with openings at different distances from the column

Revista IBRACON de Estruturas e Materiais, 2020
: The increase in the use of flat slabs and the need of the openings for the passage of installations, such as hydraulic and electrical, which significantly reduces the punching shear resistance capacity of the slab, makes the understanding of the ...
