Fire flame effect on some properties of hybrid fiber reinforced LECA lightweight self-compacting concrete

Magazine of Civil Engineering
This research aims to produce lightweight self-compacting concrete (LWSCC) using lightweight expanded clay aggregate (LECA) as coarse aggregate. The additional aim is to study the influence of steel fiber and hybrid fibers (steel and polypropylene (PP ...

Study on the failure mechanism of the shield excavation face in the sandy cobble stratum under different buried depths

Deep Underground Science and Engineering, Volume 5, Issue 2, Page 410-425, June 2026.
Abstract One of the significant challenges faced in shield tunnel construction is the risk of collapse resulting from abrupt changes in soil conditions in advance of the working face, particularly within the sandy cobble stratum. This study aims to effectively manage these sudden variations and to further investigate the failure mechanisms associated ...

Using Edible Plant and Lightweight Expanded Clay Aggregate (LECA) to Strengthen the Thermal Performance of Extensive Green Roofs in Subtropical Urban Areas

Energies, 2019
Gazing at natural landscapes and participating in agricultural activities can elicit psychophysiological restoration. However, most buildings are constructed merely to meet the minimum legal requirements for structure weight load.

Salt Stress Induces Imbalanced ADI Pathway Gene Expressions in Pediococcus acidilactici Drives Citrulline Accumulation as an Ethyl Carbamate Precursor in Soy Sauce

Food Bioengineering, Volume 5, Issue 2, Page 171-181, June 2026.
ABSTRACT Citrulline is the main precursor of a carcinogen compound ethyl carbamate (EC) in soy sauce. Accumulation of citrulline is mainly related to metabolism of arginine by Pediococcus acidilactici via the arginine deiminase (ADI) pathway during soy sauce fermentation.

Comparative genomics of eukaryotic small nucleolar RNAs reveals deep evolutionary ancestry amidst ongoing intragenomic mobility

BMC Evolutionary Biology, 2012
Background Small nucleolar (sno)RNAs are required for posttranscriptional processing and modification of ribosomal, spliceosomal and messenger RNAs. Their presence in both eukaryotes and archaea indicates that snoRNAs are evolutionarily ancient.

Generalist‐pollinated Arabis alpina exhibits floral scent variation at multiple scales

Nordic Journal of Botany, Volume 2026, Issue 6, June 2026.
Plants that depend on animals for reproduction often use complex floral traits to attract pollinators. Floral scent is recognized as part of the pollinator attraction module and can be shaped by plant‐pollinator interactions. In recent decades, research has started to reveal the dynamic properties of floral scent, identifying patterns of spatial and ...

Bacterial microbiota of Aedes aegypti mosquito larvae is altered by intoxication with Bacillus thuringiensis israelensis

Parasites & Vectors, 2018
Background Insect microbiota is a dynamic microbial community that can actively participate in defense against pathogens. Bacillus thuringiensis (Bt) is a natural entomopathogen widely used as a bioinsecticide for pest control.
