WLI, XPS and SEM/FIB/EDS Surface Characterization of an Electrically Fluted Bearing Raceway
LubricantsElectrical bearing currents may disturb the performance of the bearings via electro-corrosion if they surpass a limit of ca. 0.1 to 0.3 A/mm2. A continuous current flow, or, after a longer time span, an alternating current or a repeating impulse-like ...

Environmental stimuli shape microglial plasticity in glioma [PDF]
, 2017 In glioma, microglia and infiltrating macrophages are exposed to factors that force them to produce cytokines and chemokines, contributing to tumor growth and maintaining a pro-tumorigenic, immunosuppressed microenvironment.

HIV‐1 establishes immediate latency in T cells expressing the viral Nef protein
FEBS Open Bio, EarlyView.Nef is a viral protein often omitted from HIV‐1 reporter viruses. Consequently, its role in viral latency is unclear. We developed three novel dual reporter HIV‐1 derivatives that express Nef and allow for detection of latent and productive infection. Using these reporters, we show that Nef does not affect the establishment of immediate viral latency ...

Analysis of Bearing Current in Doubly-fed Induction Generator for Wind Power
Kongzhi Yu Xinxi Jishu, 2016 As the rotor of doubly-fed induction generator (DFIG) for wind power is supplied by PWM voltage source inverter, bearing damage caused by bearing current is very common.Through analyzing the generation mechanism of common mode voltage, it presented a ...

Force characterization and coordinate transformation of a fixed-bias flux three-phase magnetic bearing [PDF]
AIP AdvancesConventional hybrid magnetic bearings employ permanent magnets (PMs) for bias flux together with actively controlled electromagnets; however, the control forces are typically obtained by modulating excitation currents on top of the bias field.

FEBS Open Bio, EarlyView.Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

Nonlinear dynamics of attractive magnetic bearings [PDF]
The nonlinear dynamics of a ferromagnetic shaft suspended by the force of attraction of 1, 2, or 4 independent electromagnets is presented. Each model includes a state variable feedback controller which has been designed using the pole placement method ...

FEBS Open Bio, EarlyView.This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.
