The experimental apparatus consisted ofmultimeters, power supply, fixture and proximity (PX032-1), as shown inFigure 5.51a. The CAD model of the experiment apparatus is shown inFigure 5.51b. The specimen was mounted into the fixture. To apply normal loads, an upper plate, two blocks, two r...
Hertz contact theory described the pure elastic deformation of a sphere under an external load3. Johnson–Kendall–Roberts (JKR) theory considered the internal surface force4. Dejaguin–Muller–Toporov (DMT) theory considered the energy of the non-contact adhe- sion forces acting surrounding the ...
I Oparin (1894-1980), a Russian biochemist and one J.B.S. Haldane (1892-1964) put forward the concept that the first living thing evolved from the non-living thing, An Indian thinker, Charak, the author of Chark Sashinta has a similar view. He held that the man and the visible wor...
To additionally explore access, uptake and use that accompany such technologies, the International Responses to COVID-19 Contact Tracing: COVID-19 APP Uptake and Use Survey was developed and used with participants living in Singapore, Australia, the United States and the United Kingdom. The articl...
Zoonotic transmissions are a major global health risk, and human–animal contact is frequently raised as an important driver of transmission. A litera
To understand the status of media exposure, social support, self-efficacy, and health literacy among middle-aged and older adults in China, and explore the impact path of media exposure on the health literacy of this population, providing a reference for promoting their physical and mental health...

The force-deformation curve consists of a brief initial non-linear and non-elastic part; the fibrous remains of the mesocarp covering the nut are flattened with some resistance exhibited by the nut, the similar behaviour has been reported for corncob (Anazodo, 1983). The second part is a ...

VAMP fluorescence (mean 1027 and 2710 a.f.u., respectively; KS test, D = 0.449, p < 0.001) was significantly lower at orphan than at dendritically apposed boutons (Figure 3D). Interestingly, orphan release sites also contained less CAZ, as reflected by lower Bassoon fluorescence (mean 824...
