Finite element analysis of components subjected to ratchetting and creep by Hardy, S.J.

“…Many components in conventional and nuclear power plant, chemical plant and aero engines may be subjected to severe loading conditions, i.e. loads which cause reverse plasticity and/or incremental growth (Ratchetting). If operating temperatures are high, creep strains may also be significant and may exacerbate the ratchetting process. …”

Public Budget Ratcheting: Do Malaysia Federal Government Agencies Adjust Their Budgets Based on Expenditure Variances? by Daw, Tin Hla, Chang, Sze Ping, Abu Hassan, Md. Isa, Micheal, Tinggi, Shaharudin, Japar

“…The contribution of the research highlights that the presence of budget ratcheting among the federal government agencies/programs of public organisations needs to be indicated to enhance budget administration regarding ratcheting.…”

Competition and ratchet hypothesis: How safe are manufacturing companies in Sub-Saharan Africa? by Olowofela, Olusola Enitan, Tonade, Akanbi M. A, Sanyaolu, Wasiu

“…It was observed, as predicted by the theoretical model that there would be substantial ratchet effects in the absence of competition. However, when subjected to ex-post competition, the ratchet effects were reduced, regardless of whether market conditions favored the firms or the managers and thereby making the manufacturing companies in Sub-Saharan Africa safer than when they were exposed to ratcheting in its conventional form.…”

Genetic and biochemical analysis of the Archaeal Helicase Hel308 by Simmons, Emily

“…Here, analysis of Hel308 translocation was performed via the introduction of site-directed mutations into both the ratchet helix of domain IV, and a highly conserved motif within domain II (motif IVa) that appears to link the ATPase domains with the ratchet helix. …”

Rheophytism in Bornean Schismatoglottideae (Araceae) by Wong, Sin Yeng

“…Phylogenetic analyses were performed by using parsimony, likelihood (RAxML and likelihood ratchet PAUP*), and Bayesian inference to determine the placement of these additional taxa within Schismatoglottideae. …”

Finite element investigation of the incremental deformation of components by Sahari, Berkawi Bin

“…Many components in conventional and nuclear power plants and chemical plants are likely to be subjected to 'severe' loading conditions, i.e. loads which would cause cyclic plastic straining and/or incremental deformation (i.e. ratchetting). For operating temperatures above the creep threshold, creep strain also occurs, which may exacerbate the ratchetting of components. …”

Biochemical analysis of Hel308 and HelQ helicases by Buckley, Ryan J.

“…DNA translocation is thought to occur through step wise movement of the helicase core, coupled to the actions of an accessory ratchet domain. These proteins possess an unconventional winged helix domain of unknown function. …”

DNA binding and unwinding by Hel308 helicase requires dual functions of a winged helix domain by Northall, Sarah J., Buckley, Ryan, Jones, Nathan, Penedo, J. Carlos, Soultanas, Panos, Bolt, Edward L.

“…In the crystal structure of archaeal Hel308 bound to a tailed DNA duplex, core helicase domains encircle single-stranded DNA (ssDNA) in a “ratchet” for directional translocation. A winged helix domain (WHD) is also present, but its function is mysterious. …”

Cooperative effects in vibrated granular systems by Pacheco Martinez, Hector Adrian

“…The mechanism responsible for the rapid rise of the intruder is shown to be fluid-enhanced ratcheting rather than simple differential drag. Lastly, we describe experiments carried out in a levitation magnet to investigate the behaviour of spheres suspended magnetically in a viscous fluid. …”
