APPLICATION OF THE KAISER EFFECT IN IN-SITU STRESS MEASUREMENT IN ROCKS - AN OVERVIEW

open access: yesRudarsko-geološko-naftni Zbornik, 2022
Knowledge of in-situ rock stress is one of the significant issues in many engineering problems. There are various methods for determining in-situ stress. Most of the common methods used for the determination of in-situ stress are time and cost consuming,

Brittleness Evaluation in Shale Gas Reservoirs and Its Influence on Fracability

open access: yesEnergies, 2020
The brittleness index (BI) is a key parameter used to identify the desirable fracturing intervals of shale gas reservoirs. Its correlation with fracability is still controversial. There have been a variety of methods proposed that can estimate BI.

Hyperosmotic stress:in situchromatin phase separation [PDF]

open access: yesNucleus, 2020
Dehydration of cells by acute hyperosmotic stress has profound effects upon cell structure and function. Interphase chromatin and mitotic chromosomes collapse ("congelation"). HL-60/S4 cells remain ~100% viable for, at least, 1 hour, exhibiting shrinkage to ~2/3 their original volume, when placed in 300mM sucrose in tissue culture medium.
