The C‐terminal domain of yeast Arginyltransferase1 is essential for its catalytic activity

open access: yesFEBS Open Bio, EarlyView.
Arginyltransferase 1 (Ate1), a eukaryotic enzyme, catalyses arginylation, transferring arginine from tRNA‐Arg to the amino terminus of the target protein. Overexpression of Ate1 in yeast is lethal and is dependent on arginylation. This study elucidates how mutations in the cofactor‐binding and active site of Ate1 and truncation of its structural ...

Finite element assisted prediction of ductile fracture in sheet bulging of magnesium alloys [PDF]

open access: yes, 2008
There is currently a growing demand for energy efficiency, particularly in reducing the rate of oil consumption. One solution in this area is for the aerospace and automotive industries to produce lighter vehicles that are more fuel efficient.

Non-Local Ductile Damage Formulations for Sheet Bulk Metal Forming

open access: yesJournal of Physics: Conference Series, 2016
A ductile damage model for sheet bulk metal forming processes and its efficient and accurate treatment in the context of the Finite Element Method is presented. The damage is introduced as a non-local field to overcome pathological mesh dependency. Since standard elements tend to show volumetric locking in the bulk forming process a mixed formulation ...

Identification and characterization of a gene conferring stress resistance in Escherichia coli and cyanobacteria

open access: yesFEBS Open Bio, EarlyView.
Functional screening identified PcSyn14890, a cyanobacteria‐specific protein that enhances growth and stress resistance in E. coli and Synechocystis PCC6803. Although we expected it to function as a molecular chaperone, it was unable to protect against thermal aggregation of GAPDH.

Study on Rotary Bending Forming Process of Torsional Damper Shell Pulley

open access: yesXibei Gongye Daxue Xuebao, 2019
To study the integral forming process of torsion damper shell pulley with characteristic structure is of great significance for producing and developing of the rotational part such as shell pulley. A processing way was proposed by combining plate bending

Comparison between incremental deformation theory and flow rule to simulate sheet-metal forming processes [PDF]

open access: yes, 2012
Numerical simulation of the deep drawing process for the manufacture of aeronautical or automotive components should predict with good accuracy the behaviour during the forming operation, taking into account, the material and the process parameters ...

Air‐Pressure–Actuated Vibroacoustic Metamaterial With Tunable Bandgap: Design, Modeling, and Characterization

open access: yesAdvanced Engineering Materials, EarlyView.
This article presents the design, modeling, and characterization of air‐pressure–actuated programmable vibroacoustic metamaterials (PVAMM). The study focuses on leveraging air pressure to dynamically tune resonance frequencies for effective noise attenuation.

A non-invasive node-based form finding approach with discretization-independent target configuration

open access: yesAdvanced Modeling and Simulation in Engineering Sciences, 2018
Form finding is used to optimize the shape of a semi-finished product, i.e. the material configuration in a forming process. The geometry of the semi-finished product is adapted so that the computed spatial configuration corresponds to a prescribed ...
