Caution is needed when translating the carbon market logic to nature credits
Both credit types share a basic premise: land users implement practices that result in a measurable and verifiable gain — either long-term carbon sequestration or an increase in biodiversity — above a baseline. Credits are issued for these…

A simple and low-cost strategy to develop antibacterial composite film of nanocellulose and stilbite zeolite particles
Isolation of cellulose from Teff straw
The cellulose employed for nanocomposite film development was extracted from Teff straw using alkali and sodium hypochlorite treatments as shown in Fig. 1. The extraction process removed hemicellulose,…

Impact of pelvic floor anatomical variations on urinary continence outcome in boys with epispadias
Achieving urinary continence is a primary, yet often elusive, goal in the surgical management of the EEC. A recent large-scale review of 350 CBE patients reported that only 25% achieved complete continence without relying on intermittent…

Unravelling the drivers of marine biodiversity across the Phanerozoic
Simulating marine biodiversity during the Phanerozoic
We base our simulations of marine biodiversity during the Phanerozoic on an updated version of the species niche and climate interaction (SNCI) model27 (named SNCI-v2 hereafter; Methods). This…

Research on topology optimization and case application of power tunnel structure based on variable density method
Example project overview
A 110-kV power tunnel was selected with a straight-wall arch configuration, featuring an internal headroom of 2.0 m × 2.3 m. The second lining was 0.25 m thick and made of C40 reinforced concrete. The reinforcement…
