In thermodynamics, thermal stability describes the stability of a water body and its resistance to mixing. [1] It is the amount of work needed to transform the water to a uniform water density . The Schmidt stability "S" is commonly measured in joules per square meter (J/m 2 ).
The degree of this response depends not only on the species, but also on the levels of insulative and metabolic adaptation. [2] Environmental temperatures below the TNZ, the lower critical temperature (LCT), require an organism to increase its metabolic rate to meet the environmental demands for heat. [ 3 ]
Crystal structure of β-glucosidase from Thermotoga neapolitana (PDB: 5IDI).Thermostable protein, active at 80°C and with unfolding temperature of 101°C. [1]In materials science and molecular biology, thermostability is the ability of a substance to resist irreversible change in its chemical or physical structure, often by resisting decomposition or polymerization, at a high relative ...
In the less extensive technique of equilibrium unfolding, the fractions of folded and unfolded molecules (denoted as and , respectively) are measured as the solution conditions are gradually changed from those favoring the native state to those favoring the unfolded state, e.g., by adding a denaturant such as guanidinium hydrochloride or urea.
In biology, homeostasis (British also homoeostasis; / h ɒ m i oʊ ˈ s t eɪ s ɪ s,-m i ə-/) is the state of steady internal physical and chemical conditions maintained by living systems. [1]
Magill said cold weather effects on iguanas depends on the size of each specimen. The larger the iguana, the colder it can tolerate for longer periods, Magill said.
Warm monomictic lakes that have experienced historically warm winters demonstrate greater thermal stability. This stability reduces mixing interactions and the oxygenation of waters. Furthermore, cold monomictic lakes may experience less cool conditions year-round leading to increased mixing and changes in thermal stratification otherwise unseen.
Cases of norovirus — the virulent, wildly contagious virus that causes vomiting and diarrhea — are increasing in the U.S., the Centers for Disease Control says, reporting double the amount of ...
