FEATURES OF GEOLOGICAL STRUCTURE AND PETROLEUM POTENTIAL OF CARBONATE SEDIMENTS ON THE WEST SIBERIAN PLATE TERRITORY

Известия высших учебных заведений: Нефть и газ, 2017
The article considers the wells that have penetrated the carbonate sediments with the geological and paleontological information. By the late Devonian epoch paleogeographic scheme they are located in certain megazones with their inherent characteristics ...

Shotgun Metagenomics of Deep Forest Soil Layers Show Evidence of Altered Microbial Genetic Potential for Biogeochemical Cycling

Frontiers in Microbiology, 2022
Soil microorganisms such as Bacteria and Archaea play important roles in the biogeochemical cycling of soil nutrients, because they act as decomposers or are mutualistic or antagonistic symbionts, thereby influencing plant growth and health.

Carbon sequestration in the subsoil and the time required to stabilize carbon for climate change mitigation

Global Change Biology
Soils store large quantities of carbon in the subsoil (below 0.2 m depth) that is generally old and believed to be stabilized over centuries to millennia, which suggests that subsoil carbon sequestration (CS) can be used as a strategy for climate change ...

Global subsoil organic carbon turnover times dominantly controlled by soil properties rather than climate

Nature Communications, 2019
Soil organic carbon (SOC) in the subsoil below 0.3 m accounts for the majority of total SOC and may be as sensitive to climate change as topsoil SOC. Here we map global SOC turnover times (τ) in the subsoil layer at 1 km resolution using observational ...

A review on earth tube heat exchanger in heating and cooling systems

Al-Qadisiyah Journal for Engineering Science, 2023
Systems for heating and cooling that use renewable energy are becoming more popular. One method for lowering ventilation heat losses and enhancing thermal comfort in buildings is the use of earth tube heat exchangers to heat or cool the air.

Atypical Long Barrows in the Cöeby Neolithic Cemetery (Trédion, Morbihan, France)? The Contribution of Electrical Surveys

Archaeological Prospection, EarlyView.
ABSTRACT The Coëby Neolithic cemetery, located in the commune of Trédion (Morbihan, France) and discovered in 1986, has been for several years the subject of a research programme focused on studying the various megalithic structures present. The spatial distribution of these remains highlights an unusual occupation of the territory, organized according
