The effect of vibration frequency on changes in the salt system of milk.
Communications in agricultural and applied biological sciences, 2014This paper presents a model study into the effect of varied frequencies (10-60 Hz) of vertical and horizontal vibrations at a constant acceleration of 1g for 60-min. exposures on the changes in the salt system of milk. It was found that the tendencies of changes in the salt system of milk under vertical and horizontal vibrations are similar and are ...

Protein Conformational Changes and Low-Frequency Vibrational Modes: A Similarity Analysis
2019The study of protein vibration and dynamics is receiving increasing attention among researchers, both from a numerical and experimental perspective. By using terahertz spectroscopy techniques, it has been shown that conformational changes, crucial for protein biological function, are strictly related to low-frequency vibrational modes.

Influence of low-frequency vibration on changes of biochemical parameters of living rats
The Journal of the Acoustical Society of America, 2004The aim of the research was to investigate how some selected biochemical parameters of living rats depend on exposure of low-frequency vibrations. Experiments were run on 30 Wistar rats randomly segregated into three groups: (I) 20 days old (before puberty), (II) 70th day after; (III) control group.

Abstract The frequency-change-type two-axis acceleration sensor uses a cross-type vibrator consisting of four bending vibrators. When coupling vibration exists between these four bending vibrators, the resonance frequency of each vibrator cannot be adjusted independently.

The C-Hal (Hal = Cl, Br, or I) bond-length change and the corresponding vibrational frequency shift of the C-Hal stretch upon the C-Hal ⋯Y (Y is the electron donor) halogen bond formation have been determined by using density functional theory computations.
