Combustion Properties of Timber in Historic Structures: Case Study of the São Pedro de Alcântara Chapel Fire

open access: yesFire and Materials, EarlyView.
ABSTRACT Timber plays a fundamental role in the fire performance of historic building components, where ageing and environmental exposure can markedly influence its physical and chemical properties. This study presents an experimental investigation of the fire behaviour of Ocotea sp.

An origin-of-life reactor to simulate alkaline hydrothermal vents. [PDF]

open access: yes, 2014
Chemiosmotic coupling is universal: practically all cells harness electrochemical proton gradients across membranes to drive ATP synthesis, powering biochemistry. Autotrophic cells, including phototrophs and chemolithotrophs, also use proton gradients to

Hydrodynamic flow and benthic boundary layer interactions shape the microbial community in Milos shallow water hydrothermal vents

open access: yesFrontiers in Microbiology
In shallow-water hydrothermal vents, the dynamic interface between the discharged reduced hydrothermal fluids and the oxidized seawater allows the establishment of gradients capable of supporting diverse and complex microbial mats.

Antarctic marine biodiversity and deep-sea hydrothermal vents.

open access: yesPLoS Biology, 2012
The diversity of many marine benthic groups is unlike that of most other taxa. Rather than declining from the tropics to the poles, much of the benthos shows high diversity in the Southern Ocean. Moreover, many species are unique to the Antarctic region.

Evidence of Vent-Adaptation in Sponges Living at the Periphery of Hydrothermal Vent Environments: Ecological and Evolutionary Implications

open access: yesFrontiers in Microbiology, 2020
The peripheral areas of deep-sea hydrothermal vents are often inhabited by an assemblage of animals distinct to those living close to vent chimneys.

ExMODE: A comprehensive resource for extremophile genomic and functional exploration

open access: yesiMetaOmics, EarlyView.
ExMODE (https://db.genomics.cn/exmode/) integrates 3518 samples to build a unified extremophile resource, which hosts 1.35 billion habitat‐specific non‐redundant genes, 5.25 million representative protein structures, 67,026 metagenome‐assembled genomes (MAGs), and 164,132 biosynthetic gene clusters (BGCs). By combining sequence‐, structure‐, and genome‐

Food-Web Complexity in Guaymas Basin Hydrothermal Vents and Cold Seeps

open access: yesPLoS ONE, 2016
In the Guaymas Basin, the presence of cold seeps and hydrothermal vents in close proximity, similar sedimentary settings and comparable depths offers a unique opportunity to assess and compare the functioning of these deep-sea chemosynthetic ecosystems ...

Mechanism of Combined Improvement of Saline‐Alkali Soil by Artificial Humic Acid and Microbial Inoculant

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT To address the widespread constraints imposed by saline‐alkaline soils on agricultural production worldwide, the combined reclamation and carbon cycle regulation effects of artificial humic acid (AHA) and a multifunctional microbial inoculant were evaluated through pot experiments. Results demonstrated that co‐application of AHA (4 g·kg−1) and

Bacterial and archaeal communities in the deep-sea sediments of inactive hydrothermal vents in the Southwest India Ridge

open access: yesScientific Reports, 2016
Active deep-sea hydrothermal vents harbor abundant thermophilic and hyperthermophilic microorganisms. However, microbial communities in inactive hydrothermal vents have not been well documented. Here, we investigated bacterial and archaeal communities in

Manure Composting as a Strategy to Mitigate Antibiotic Resistance Dissemination in Agricultural Systems

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Livestock manure is a valuable agricultural resource but may introduce antibiotic residues and antibiotic resistance genes (ARGs) into the environment. This review critically evaluates the fate of antibiotics and ARGs during manure composting and identifies the principal factors controlling their attenuation.
