Although bladed disks are nominally designed to be cyclically symmetric (tuned system), the vibration hair cream characteristics of all blades on a disk are slightly different due to the manufacturing tolerance, deviations in the material properties, and wear during operation.These small variations break the cyclic symmetry and split the eigenvalue
Conservation versus traditional cattle farming - the economic implications
In many areas of South Africa traditional valve replacement subsistence farming practices entail overstocking of cattle.The resulting damage to the veld can be arrested only by providing the farmers with economic incentives to reduce stocking densities.In this paper cattle offtake strategies are investigated with a view to maximising revenue at low
PEEP Role in ICU and Operating Room: From Pathophysiology to Clinical Practice
Positive end expiratory pressure (PEEP) may prevent cyclic opening and collapsing alveoli in acute respiratory distress syndrome (ARDS) patients, but it may play a role also in general anesthesia.This review is organized in two Towels sections.The first one reports the pathophysiological effect of PEEP on thoracic pressure and hemodynamic and cereb

Iron, Ferritin, Hereditary Ferritinopathy, and Neurodegeneration
Cellular growth, function, and protection require proper iron management, and ferritin plays a crucial role as the major iron sequestration and storage protein.Ferritin is a 24 subunit spherical shell protein composed of both light (FTL) and heavy chain (FTH1) subunits, possessing complimentary iron-handling functions and forming three-fold and fou
