Towards a Model-Based Methodology for Rating and Monitoring Wear Risk in Oscillating Grease-Lubricated Rolling Bearings

Lubricants
Oscillating grease-lubricated slewing bearings are used in several applications. One of the most demanding and challenging is the rotor blade bearings of wind turbines. They allow the rotor blades to be turned to control the rotational speed and loads of

Chiral separation of chloroalkanes with the chromatographic column onboard Martian rovers

FEBS Letters, EarlyView.
Computer image of the Rosalind Franklin Rover of ESA's ExoMars mission. ExoMars is scheduled to land on planet Mars in Oxia Planum in 2029. This area represents an interesting spot to look for biosignatures. Investigations of ExoMars include measurement on molecular chirality. We show that chiral chloroalkanes, that have been identified on Mars, can be

Pin-bearing strengths for bolted connections in fibre-reinforced polymer structures [PDF]

, 2011
Presented in this paper are pin-bearing strengths for pultruded fibre-reinforced polymer materials that are required in order to check the bearing resistance when designing bolted connections. For steel pin diameters up to 16 mm, equivalent test results,

Comparative Analysis of the Microstructure and Tribological Behaviors of Ni-, Fe-, and Co-Based Plasma Cladding Coatings

Metals
Nickel-, iron-, and cobalt-based alloy coatings were fabricated on the surface of U75V steel utilizing plasma cladding technology. This study investigates the microstructure, mechanical properties, and tribological performance of the coatings.

RNA‐related functions of BRCA2 in transcription, replication, and genome stability

FEBS Letters, EarlyView.
Beyond its role in homologous recombination, BRCA2 regulates R‐loop homeostasis, DNA–RNA hybrid resolution, RNA polymerase II dynamics, and transcriptional activation. Disruption of any of these functions can contribute to genome instability, inflammatory signaling, and tumorigenesis. BRCA2 is a central tumor suppressor protein best known for its roles

A context‐dependent modulatory role for eIF6 in acquired resistance to vemurafenib in melanoma

FEBS Letters, EarlyView.
Acquired resistance to vemurafenib upregulates the translation factor eIF6 in melanoma cells. Silencing eIF6 in resistant cells reduces proliferation and partially restores drug sensitivity, whereas its overexpression increases sensitivity across melanoma lines regardless of BRAF status, via modulation of mTOR, S6K, and MAPK signaling.
