Arthritis Care &Research, EarlyView.Objective In complex diseases, it is challenging to assess a patient's disease state, trajectory, treatment exposures, and risk of multiple outcomes simultaneously, efficiently, and at the point of care. Methods We developed an interactive patient‐level data visualization and analysis tool (VAT) that automates illustration of the trajectory of a ...

The influence of surface hardning of pins on the longevity of hauling chains of conveyors [PDF]
, 2011 It is show that the friction strengthening essentially increases the conveyors chain durability. Thus, under friction without lubrication the wear-resistance of a pair of 40HN2MA and 40HN2MA steel increases more than in 8 times after friction ...

Arthritis Care &Research, Accepted Article.Objective Somatic items used in depression assessments can potentially overlap with symptoms related to physical illness, including systemic sclerosis (SSc). No studies have looked at whether somatic depression items may be influenced by diffuse versus limited SSc disease subtypes, which are associated with varying degrees of symptom presentation.

Tribological properties of nano-BN/TiN lubricating additives modified with oleic acid
Cailiao gongcheng, 2020 BN, TiN and BN/TiN nano-additives were modified by oleic acid, characterized by Fourier transform infrared spectroscopy. The tribological properties of lubricating oil nano-additives were tested by four-ball friction and wear tester.

Friction torque, temperature and roughness in roll-slip phenomenon for polymer–steel contacts [PDF]
, 2011 The current study gives an insight of the roll-slip phenomenon of polymer-metal pair where priority is given to measurement techniques, test duration and the behavior of the polymer. A systematic tribological measurement was used to identify the friction

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy
Advanced Engineering Materials, EarlyView.An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.
