Study on mechanism of mechanical activation
Materials Science and Engineering: A, 1997A mixture of ilmenite and graphite with a mass ratio (1:1) was ball milled at room temperature and subsequently annealed under Ar flow. The enhanced carbothermic reactions were monitored by using thermogravimetric analysis and X-ray diffraction analysis.

The mechanics of active muscle
Proceedings of the Royal Society of London. Series B - Biological Sciences, 1953Abstract When a frog’s or toad’s sartorius is rapidly released during a maintained isometric contraction its tension drops immediately and is redeveloped later. The extent of release required to reduce the tension to zero is 3 to 4 % of the length of the muscle.

Mechanisms of Plasminogen Activation by Mammalian Plasminogen Activators
Enzyme, 2017Plasminogen activators convert the proenzyme plasminogen to the active serine protease plasmin by hydrolysis of the Arg^560-Val^561 peptide bond. Physiological plasminogen activation is however regulated by several additional molecular interactions resulting in fibrin-specific clot lysis.

Science, 1995
S. Buratowski discusses two papers in this issue of Science (Sauer et al ., pp. 1783 and 1825 ) that show that the basal transcription factor complex TFIID is a target of transcriptional activators.

A mechanized urease activity assay
Enzyme and Microbial Technology, 2019Two fully mechanized flow analysis systems for urease activity assays have been developed, characterized and compared. Both of them are based on almost the same compact system of solenoid micropumps and microvalves controlled and actuated by highly effective, low-power and economic Arduino microcontroller. For photometric detection of ammonia formed in

Mechanisms controlling CDK9 activity
Frontiers in Bioscience, 2006This review primarily focuses on the mechanisms that modulate CDK9 activity and its recruitment to cellular genes, where it phosphorylates the C-terminal domain of RNA polymerase II (RNAPII) as well as negative elongation factors. CDK9 associates with each of four cyclins (T1, T2a, T2b and K), forming distinct positive transcription elongation factors (

MECHANISMS OF INFLAMMATION AND LEUKOCYTE ACTIVATION
Medical Clinics of North America, 1997This article reviews the current status of the knowledge of mechanisms of activating inflammatory responses. It also describes inflammatory mediators, adhesion proteins, the inflammatory process itself, and the molecular mechanisms controlling inflammatory cell activation and regulation.

It is well known1–5 that molecules in gaseous media become activated in a direct collision between the translators. When a reference molecule undergoes collision with another molecule, the total kinetic energy of the two molecules is redistributed between them.
