Euler-Lagrange coupling method is used to establish the fluid-structure interaction model for tires with different tread patterns by obtaining grounding mark and normal contact force between tire road surface during rolling. The altering of load force, pressure, water film thickness in relation effect on tire-road both constant speed critical hydroplaning was analyzed. Results show that are pos...

The article presents the results of research on influence pressure in car tires braking distance. Tires with lower than nominal pressure, higher and for comparison were analyzed. tests carried out a bituminous surface typical most road surfaces Poland. Six dry surface, wet covered snow. cars equipped sets summer winter tires. tire distance was two practically identical very similar curb weight ...

Preventing pressure ulcers (PUs) in an acute hospital setting is a complex activity. It clearly sits within the definition of implementing complex care to a complex group of patients in a complex setting (Raine et al, 2016). The multiple comorbidities and increased acuity of the at risk patient result in many conflicting care priorities. In addition there are many changes in healthcare provisio...

Pediatric neurosurgical patients present a unique set of anesthetic challenges that include treatment of increased intracranial pressure (ICP), the use of positions other than supine, and the anesthetic implications of neurophysiologic monitoring. These and other general considerations are addressed in the first part of this chapter, followed by a discussion of anesthetic techniques for common ...

Slow waves in intracranial pressure (ICP) and related signals seems of interest to evaluate the dynamic autoregulation, i.e. by comparison of the frequency links between an intracranial signal, e.g. ICP, cerebral blood velocity (CBV), and arterial blood pressure (ABP). To clarify the links, we compared two frequency methods based on coherence function to estimate the influence of ICP, ABP and C...

Trucking fleets and owners of commercial vehicles utilize both new and retread tires on their vehicles in the United States. Retread tires are used primarily for the cost advantage they provide over a similar new tire. Despite the advantages that retreaded tires may bring, public perception is that retread tires are less safe than new tires as evidenced by the amount of tire debris frequently f...

Abstract The mortality of road accidents quadruples when, in addition to motorists, a motorcyclist is also involved. higher influenced by the greater exposure rider injuries during impact. This problem can be mitigated reducing, even slightly, impact’s speed. Bench tests carried out previous studies showed considerable influence inflation pressure on properties motorcycle tires. It could theref...
