Background Safe and effective vaccines are urgently needed to end the COVID-19 pandemic
caused by SARS-CoV-2 infection. We aimed to assess the preliminary safety, tolerability, …

We study the ${L^ p} $ Dirichlet problem for the Stokes system in Lipschitz domains. Optimal
estimates are obtained when the dimension $ n= 3$. In the case of $ n\geq 4$, we establish …

The explosibility of hybrid H 2 /Ti dust in the production of metal hydride TiH 2 was
simulated and studied using a 20-L spherical vessel. The influential factors for the explosion …

Malnutrition is common in long-stay elderly hospitalized patients and their dietary intakes are
often poor, despite the provision of adequate quantities of food to meet patient needs. The …

Ultrasonic gas flow meter has unique advantages and good application prospects for
measuring the gas flow rate in medium to large diameter pipelines. However, there is energy …

An experimental investigation on the explosion characteristics of hydrogen-air mixtures
diluted with inert gases (Ar, N 2 , CO 2 ) was carried out in a cylinder chamber at room …

The effect of particle size polydispersity (σ D ) on coal dust explosibility was studied using a
20-L spherical explosion test apparatus. Four kinds of blends with a fixed median diameter (…

We reported an experimental study on the explosion characteristics of hydrogen-methane-air
mixtures in a closed vessel at normal pressure and temperature. The explosion parameters…

In this study, we performed experiments in a closed cylinder vessel to investigate the explosion
behaviors of H 2 /N 2 O and CH 4 /N 2 O mixtures with various equivalence ratios (φ) …

-198-is one of seven major dialects of Chinese. It has three types of stop sounds (traditionally
they are described as voiceless unaspirated, voiceless aspirated and voiced). YR Chao …
