The optimized experimental parameters of degradation obtained with a four-factor at three-level orthogonal array experimental design L18(3) were temperature, rotation speed, inoculum size and liquid level by Corynebacterium variabile in the shaking bottle as 33 , 22h after shaking at the same temperature and 120 rpm for 14h, 4%, 80mL in 150mL triangle bottle, respectively. Among four factors, l...

Chest clapping, vibration, and shaking were studied in 10 physiotherapists who applied these techniques on an anesthetized animal model. Hemodynamic variables (such as heart rate, blood pressure, pulmonary artery pressure, and right atrial pressure) were measured during the application of these techniques to verify claims of adverse events. In addition, expired tidal volume and peak expiratory ...

OBJECTIVES To determine if the amount of salt delivered by standard salt shakers commonly used in English independent takeaways varies between those with five and 17 holes; and to determine if any differences are robust to variations in: the amount of salt in the shaker, the length of time spent shaking, and the person serving. DESIGN Four laboratory experiments comparing the amount of salt d...

The formation of β-sheet rich prion oligomers and fibrils from native prion protein (PrP) is thought to be a key step in the development of prion diseases. Many methods are available to convert recombinant prion protein into β-sheet rich fibrils using various chemical denaturants (urea, SDS, GdnHCl), high temperature, phospholipids, or mildly acidic conditions (pH 4). Many of these methods also...

This study aims to investigate and optimize the effects of the main parameters including the particle size, gravity and magnetic separation combination, high gradient magnetic separation, magnetic field intensity, shaking table slope, washing water flow, and electrostatic separation upon the rare earth element (REE) recoveries from iron mine waste. The electron microprobe showed that high amoun...

Combined withering and shaking processes are key steps in the formation of characteristic floral fruity aromas black teas. However, effect sequencing on volatile compounds aroma tea has not been evaluated to date. This study used headspace solid-phase microextraction gas chromatography-tandem mass spectrometry detect teas after withering-shaking shaking-withering processing. Five main different...

This paper presents a dynamic nonlinear numerical simulation of a 5-story full-scale steel frame structure based on Perform-3D. Flexibility-based fiber element and Maxwell model are adopted for structure member simulation after a post analysis of the shaking table test of a 4-story full-scale steel frame. The author simulates the low cyclic reciprocating load test for the steel members with fib...
