Natural frequencies of polar orthotropic annular plates [PDF]
, 1973 The classical Rayleigh-Ritz method with simple polynomials as admissible functions has been used for obtaining natural frequencies of transversely vibrating polar orthotropic annular plates.

NATURAL FREQUENCIES OF A SHORT CURVED PIPE [PDF]
, 1994 The natural frequencies are determine for a short curved pipe. A shell theory is developed in toroidal coordinates, based on the Mushtari-Vlasov-Donnell assumptions.

The influence of the notches on the natural frequencies [PDF]
Applied and Computational Mechanics, 2007 The simplification of the FEM model (the missing of a notch or a crack) generally means the modification of the natural frequencies. An analysis of these changes is matter of this paper.

FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...

Single‐molecule DNA flow‐stretch assays for high‐throughput DNA–protein interaction studies
FEBS Open Bio, EarlyView.We describe an optimised single‐molecule DNA flow‐stretch assay that visualises DNA–protein interactions in real time. Linear DNA fragments are tethered to a surface and stretched by buffer flow for fluorescence imaging. Using λ and φX174 DNA, this protocol enhances reproducibility and accessibility, providing a versatile approach for studying diverse ...

The natural frequencies of muted circular drums. [PDF]
The Journal of the Acoustical Society of America, 2010 The natural frequencies of circular drum heads are calculated by the use of finite elements. The results for unmuted drum heads are almost identical to the well known analytical solution expressed in Bessel functions. Mutes of various sizes and shapes are used to stop a section of the head from vibrating.
