Analysing the methods for determining coefficient of resistance to car wheels rolling [PDF]
Avtomobilʹnyj Transport (Harʹkov), 2020 Problem. When simulating the operation of automatic or automated driver assistance systems, it is necessary to take into account the rolling resistance of the car wheels the moment the car begins to move on a slope, which necessitates the choice of a ...

Wheelchair tire rolling resistance and fatigue
The Journal of Rehabilitation Research and Development, 1985 The hysteresis loss theory of rolling resistance is developed for solid rubber wheelchair tires. The analysis is used to correlate test data for a clay-filled natural rubber and a polyurethane tire material. A discussion of tire rolling work, hysteresis loss factor measurement, and rolling loss measurement is presented.

Molecular Oncology, EarlyView.The kinase SRPK1 directly interacts with the protein TOPBP1 and regulates the pre‐mRNA splicing of WIZ thereby contributing to the activation of the ATR/CHK1 replicative checkpoint in response to replicative stress. This allows cancer cells' genomic stability and survival.

Manual wheelchair's turning resistance: swivelling resistance parameters of front and rear wheels on different surfaces [PDF]
, 2019 Purpose: Daily locomotion with a manual wheelchair includes curvilinear movements. However, little is known about the resisting forces in play during turning manoeuvres where the wheels are generally both rolling and swivelling.
