On the other hand, the reduction of sample mass fed in ball mill corresponded to enhancement of fineness of CBP. Meanwhile, qualitative evaluation of three-dimensional reconstruction of SEM images using ImageJ proved that significant enhancement of fineness led to reduction of surface roughness.
In this study, hyperpolarized (HP) 129 Xe MR ventilation and 1 H anatomical images were obtained from 3 subject groups: young healthy volunteers (HV), subjects with chronic obstructive pulmonary disease (COPD), and age-matched control subjects (AMC). Ventilation images were quantified by 2 methods: an expert reader-based ventilation defect score percentage (VDS%) …
= 3 for ball bearings = 10/3 for roller bearings, as used typically in axlebox applications The basic rating life for a specific bearing is based on the basic dynamic load rating according to ISO 281 . The equivalent bearing load has to be calculated based on the bearing loads acting on the bearing via the wheelset journal and the axlebox housing .

First Published: 23 July 2021. An in situ EPR cell with a well-defined electrochemical response is designed to understand the lithiation/deposition behavior occurring on the graphite anode of the Li-ion battery. Li deposition on the graphite electrode occurs at +0.04 V (vs. Li + /Li) at a scan rate of 0.04 mV s −1.
