Particle motion and stain removal during simulated abrasive tooth cleaning [PDF]
, 2007 Stain removal from teeth is important both to prevent decay and for appearance. This is usually achieved using a filament-based toothbrush with a toothpaste consisting of abrasive particles in a carrier fluid.

Effects of velocity-slip and viscosity variation in hydrostatic step-seal [PDF]
Jurnal Tribologi, 2018 In this work, a new scratch test method - multi-pass dual-indenter scratch test - is used to estimate the abrasion resistance of C120 steel. This steel is used in the moulds manufacture for injection of plastic materials filled with glass fibres that are

Mechanisms of IgE‐mediated food allergy and the role of allergen‐specific B cells
FEBS Letters, EarlyView.Food allergy arises when allergen‐specific B cells preferentially produce immunoglobulin E (IgE) antibodies against harmless foods. This article explains the mechanisms driving IgE‐mediated reactions, highlights the central role of these B cells, and discusses how natural tolerance (NT) and oral immunotherapy (OIT) can reshape allergic immune responses.
