air current, current of air, wind - air moving (sometimes with considerable force) from an area of high pressure to an area of low pressure; "trees bent under the fierce winds"; "when there is no wind, row"; "the radioactivity was being swept upwards by the air current and out into...
Attachment 2— AFWA FORM 2, AIR FORCE WEATHER AGENCY (FOA) QUARTERLY/ANNUAL TEAM AWARD SCORE SHEET 16 来自 static.e-publishing.af.mil 喜欢 0 阅读量: 20 作者: AFW Agency 摘要: 3.2. Multiple Category Winners. An individual who wins in multiple categories (e.g., small team, large team, ...
The mechanical strength of both fresh and used particles for all the oxygen carriers was determined using a Shimpo FGN-5 crushing strength apparatus. The value was estimated as the force needed to fracture a particle and it was calculated as the average of 20 different measurements on randomly ...
Five years ago, AMM andNikeassembled the Air Force 1 “Hand Wash Cold” in high and low-top form. Now, the two are looking to the Air Max 95 as a canvas for their collaborative creativity. For its initial preview, the layered upper sees various muted pink and purple hues adorn each o...
During operations in support of Desert Storm, the United States Air Force (USAF) flew nearly 15,000 sorties dedicated to aerial refueling in which their fleet refueled approximately 46,000 aircraft with approximately 700 million pounds of fuel [4]. The requirement to refuel will only increase in...
(ref.69), EIA form 930 (ref.70), the EPA NEEDS v.5.16 platform43, as well as the EPA eGRID database56. We use publicly available census data60for state-level population estimates and census data63for evaluation of impacts by race and ethnicity. We use the Global Burden of Disease ...
The inertial force on the airFaequals the applied force of the lungsFL, given in Equation (6). Solving for the frequencyfyields our theoretical prediction for sniffing frequency which we callf1: $${f}_{1}=\sqrt{\frac{P{r}_{{\rm{t}}}^{4}}{4\rho {V}_{{\rm{sn}}}{V}_{{\...
but the clicky 1mm travel and solid key pitch make typing a dream. Apple’s pedigree for world-class trackpads continues here too. The “Force Touch” haptics are pleasingly tactile and the sheer size of the trackpad makes it a much more pleasant experience than much of the competition. Th...
GT pneumatic actuator is driven by air source through piston in cylinder to drive gear rack and other components, and finally converts to output torque force to control valve opening and closing. It can be divided into two functional specifications: single-acti...
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...
