Influence of Drilling Fluid Temperature, Density, and Salinity on Borehole Stability in Permafrost Strata

Processes
In the drilling process in permafrost strata, the mass and heat transfer effects may thaw the strata around the boreholes and decrease the content of pore ice, thus causing the mechanical properties of the strata to deteriorate greatly, thus influencing the stability of the borehole walls.

Disposable low-cost cardboard incubator for thermoregulation of stable preterm infant – a randomized controlled non-inferiority trial

EClinicalMedicine, 2021
Background: Incubators and radiant warmers are essential equipment in neonatal care, but the typical 1,500 to 35,000 USD cost per device makes it unaffordable for many units in low and middle-income countries. We aimed to determine whether stable preterm

A Decrease to Low Carbonate Clumped Isotope Temperatures in Cryogenian Strata [PDF]

AGU Advances, 2020
AbstractPreglacial and synglacial low‐latitude carbonate sediments of the Elbobreen Formation, NE Svalbard, preserve facies changes associated with low‐latitude glacial advance in Cryogenian “Snowball Earth” episodes (717–635 Ma). We present the first application of carbonate clumped (Δ47) isotope thermometry on synglacial Snowball Earth carbonates and

Homogeneous Selection and Dispersal Limitation Dominate the Effect of Soil Strata Under Warming Condition

Frontiers in Microbiology, 2022
Global warming is likely to affect the underground microbial communities in various ecosystems, but the response of soil microbial communities along a vertical depth profile to global warming has been elusive.

Effects of mine strata thermal behavior and mine initial temperatures on mobile refuge alternative temperature [PDF]

Mining Engineering, 2017
Federal regulations require the installation of refuge alternatives (RAs) in underground coal mines. Mobile RAs have a limited ability to dissipate heat, and heat buildup can lead to a life-threatening condition as the RA internal air temperature and relative humidity increase. The U.S.

Investigation on the mutation effect induced by the coupled destabilization of fault and overburden rock strata during coal mining

Meitan xuebao, 2023
The frequent occurrence of coal burst in coal mines is closely related to the destabilization of complex geological formations, and the fault as a typical geological structure is an important factor in inducing dynamic coal burst disaster. In this study,
