In recent years, as the advent of new aircraft and new equipment has imposed higher demands on the physical and psychological qualities of flight personnel, the PLA Air Force's pilot recruitment program has been continuously enhancing the scientific rigor and precision of its selection criteria, the...
The airman, who has been in the service for about 10 years, initially crossed out the line when recently signing the Defense Department form required for re-enlistment. In a seeming reversal of the Air Force’s previous stance that the “So help me God” portion was optional, the airman ...

2010). This phenomenon causes an intense loss in the osmotic driving force (McCutcheon and Elimelech 2008), and since it occurs in the support layer, it cannot be removed by increasing the flow rate turbulence (Zhao et al. 2012a). With the intention to minimize the ICP problem, it was ...
Comparing to the H2/N2 cell, the current densities are higher for the H2/air cell, possibly due to the extra driving force from O2 in air. Interestingly, ammonia was also produced on the air side with a small amount at the H2 side when the formation rate is relatively high (Fig. 4B)...
The Ekman layeris the layer in a fluid where force balance between pressure gradient force, turbulent drag and coriolis force are balanced. It was named after scientist Vagn Walfrid Ekman who explained the phenomena for the first time. Ekman layer extends to height of 300–500 m. In this la...
Thus, significantly increased drafting force originating from more residual charges on the droplets led to the breaking of the partial nanonets during the flight of the phase separated liquid film, and this resulted in larger pore size of the nanonets than those of membranes obtained from solutions...
Due to dipole attractions and electrostatic force of attraction, SPI can attract PM particles. SPI combines with Bacterial Cellulose (BC) synthesized during fermentation of gluconacetobacterxylinus possessing a 3D nano-network that helps to filter PM particles physically. Removal efficiency for PM2.5 ...
research, in order to shed greater understanding of the development and evolution of research in fuel consumption in the air transport industry and to identify the potential research areas for further research and improvement. We present this simple meta-analysis result in the form of tables and ...
