Tribological optimization of dry forming tools
, 2022 S.78-82Waste prevention and an efficient use of resources becomes more and more important in industry from both an economic and environmental point of view. Especially in forming processes such as deep drawing, lubricants are nowadays still an inevitable

FEBS Letters, EarlyView.Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Scientific ReportsDue to the widespread industrial use of gears, a mass production method with high economic efficiency is essential. Flow forming is a novel manufacturing technique that not only forms the gear but also performs hardening by adding a thin layer of desired

Memory for the form and force of declaratives and interrogatives [PDF]
Memory & Cognition, 1980 Memory for the illocutionary force and surface form of direct and indirect speech acts was studied in two recall tasks. Both examined the effects of the context of original presentation on subjects’ ability to recall declarative and interrogative sentences. Subjects more accurately recalled the verbatim form of indirect requests and offers than that of

FEBS Letters, EarlyView.Vacuolar H+‐ATPase (V‐ATPase) is a multisubunit rotary proton pump that acidifies intracellular compartments. Using elastic network models, we identified conserved hinge residues that govern its large‐scale functional motions. We show that intrinsically encoded ‘soft modes’ drive critical functional transitions, including rotary catalysis and ...

Comparing the paths of Hedgehog release in artificial and natural settings
FEBS Letters, EarlyView.Hh morphogens require solubilization factors to overcome their tight association with the plasma membrane and signal to distant cells, but the precise functions of these factors are controversial. Here, we use published in vivo observations as the most relevant evidence to test their suggested functions and discuss contradictions and gaps between in ...
