Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Fatigue assessment of a FSAE car rear upright by a closed form solution of the critical plane method

open access: yesFracture and Structural Integrity
Material fatigue is extensively discussed and researched within scientific and industrial communities. Fatigue damage poses a significant challenge for both metallic and non-metallic components, often resulting in unexpected failures of in-service parts.

Lost and Finding: Experiences of Newly Graduated Critical Social Workers [PDF]

open access: yes, 2019
The first year of social work practice can be very stressful for new practitioners. Practice develops in response to the meaning we place on what we do and on our professional goals.

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

open access: yesFEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Multiaxial Fatigue Lifetime Estimation Based on New Equivalent Strain Energy Damage Model under Variable Amplitude Loading

open access: yesCrystals
The largest normal stress excursion during contiguous turn time instants of the maximum torsional stress is presented as an innovative path-independent fatigue damage quantity upon the critical plane, which is further employed for characterizing fatigue ...

Evaluation of an energy-based approach and a critical plane approach for predicting constant amplitude multiaxial fatigue life

open access: yesInternational Journal of Fatigue, 2000
A new energy-based approach for predicting constant amplitude multiaxial fatigue life is described. The approach is based on cyclic plastic and elastic strain energy densities and takes into account effects of stress-state and mean stresses. A wide range of test data is used to evaluate the approach as well as a critical plane approach based on maximum

Investigating transcription factor dynamics in health and disease using FRAP

open access: yesFEBS Letters, EarlyView.
FRAP analysis of GFP‐tagged transcription factors reveals how molecular mobility and target engagement change in response to drug treatment. By combining live‐cell imaging, quantitative model fitting, and statistical analysis, this approach uncovers transcription factor dynamics linked to disease mechanisms, providing a powerful framework for ...

Finite element modeling and critical plane analysis of a cut-and-chip experiment for rubber

open access: yes, 2021
Rubber surfaces exposed to concentrated, sliding impacts carry large normal and shearing stresses that can cause damage and the eventual removal of material from the surface.

Bekentenissen van een Decaan [PDF]

open access: yes, 2012
Tussen Augustinus en Rousseau is de zelfbeschouwing verschoven van Belijdenis naar Bekentenis, van een theocratische context naar een psychologische. Het is de vraag of het daaruit resulterende egocentrisme van de moderne tijd vooruitgang impliceert.
