Exact seismic response of smooth rigid retaining walls resting on stiff soil [PDF]
, 2020 The assessment of forces exerted on walls by the backfill is a recurrent problem in geotechnical engineering, owing to its relevance for both retaining systems and underground structures.

Colony organization in the green alga Botryococcus braunii (Race B) is specified by a complex extracellular matrix [PDF]
, 2012 Botryococcus braunii is a colonial green alga whose cells associate via a complex extracellular matrix (ECM) and produce prodigious amounts of liquid hydrocarbons that can be readily converted into conventional combustion engine fuels.

A two-rigid block model for sliding gravity retaining walls [PDF]
, 2013 This paper presents a new two rigid block model for sliding gravity retaining walls. Some conceptual limitations of a direct application of Newmark's sliding block method to the case of retaining walls are discussed with reference to a simple scheme of ...

Model test on the load bearing mechanism of inclined pile-sheet retaining wall
矿业科学学报The inclined pile-sheet retaining wall differs from the traditional pile-sheet retaining wall in the stress and distribution of earth pressure behind the wall because of the inclination of the retaining plates. Its mechanism is unclear while its existing

An Interface View of Directed Sandpile Dynamics
, 2001 We present a directed unloading sand box type avalanche model, driven by slowly lowering the retaining wall at the bottom of the slope. The avalanche propagation in the two dimensional surface is related to the space-time configurations of one ...

Rethinking plastic waste: innovations in enzymatic breakdown of oil‐based polyesters and bioplastics
FEBS Open Bio, EarlyView.Plastic pollution remains a critical environmental challenge, and current mechanical and chemical recycling methods are insufficient to achieve a fully circular economy. This review highlights recent breakthroughs in the enzymatic depolymerization of both oil‐derived polyesters and bioplastics, including high‐throughput protein engineering, de novo ...

FEBS Open Bio, EarlyView.Comparative analysis of chloroplast genomes from 14 genera of Thymelaeaceae revealed variation in gene content, ranging from 128 to 142 genes, primarily influenced by IR expansion/contraction events and pseudogenization of ndhF, ndhI, and ndhG. Two large inversions were detected within the large single‐copy region, including a synapomorphic inversion ...
