Effect of extraction methods of polysaccharides from Imai on digestion and fecal fermentation .

This study employed extraction methods, namely acid, alkaline, ultrasonic-assisted, hot-water, and dual enzyme-assisted extraction to extract polysaccharides from Imai (TMIPs), and investigated them for intestinal digestion and fecal fermentation . Furthermore, using fructo-oligosaccharide as a positive prebiotic control, the impact of these TMIPs as carbon sources on the growth of and in liquid culture was assessed. The results showed that all fractions transit through the gastrointestinal tract without degradation.

Noise investigation of an electrostatic accelerometer by a high-voltage levitation method combined with a translation-tilt compensation pendulum bench.

A high precision electrostatic accelerometer has widely been employed to measure gravity gradients and detect gravitational waves in space. The high-voltage levitation method is one of the solutions for testing electrostatic accelerometers on the ground, which aims at simultaneously detecting all six-degree-of-freedom movements of the electrostatic accelerometers engineering and flight prototypes. However, the noise performance in the high-voltage levitation test is mainly limited by seismic noise.
