Observations of anti-repeating earthquakes are not limited to local or regional seismicity. We also identified such event pairs within massive acoustic emission (AE) activity (tiny earthquakes, here below Mw −3.5) induced during small-scale hydraulic fracturing experiments conducted in crystalline rock...
where Vbis the DC breakdown voltage, p is the pressure of the gas, d is the gap distance in meters, A and B are constants that depend on the surrounding gas, and γseis the secondary electron emission coefficient. The secondary electron emission...
To calculate the drag force, it is assumed that the drag coefficient (CD) is typically around 2.2 and that the cross-sectional area (A) of Starlink satellites is approximately 15.45 m2 (Hardy 2020). We attempted to examine the decay of altitude on Starlink satellites using the Two Line ...
The secondary electron emission coefficient is the point where incident particles have enough kinetic energy that when they strike other particles, they induce the emission of secondary particles.Calculating the Breakdown Voltage of Air Per Inch An air gap breakdown voltage table can be used to look...
Release fractions based on environmental release categories(ERC) or SPERC and emission days. Please note thatdefault release percentage and emmission days in EUSES shall not be used. Read:How to calculate environmental emissions of chemical substances. ...
Parameters (10) and (11) are used to calculate the optimistic ideal and the opposite optimal solutions accordingly.zij*+=max(z1*+,z2*+,⋯,zp*+)Di−=∑jx(zij*−zj*−)2 The significance of resources tourism growth force Ci is acquired as:Ci=Di−/(Di++Di−) 3.2. The LMD...

Due to the continuous progress of constructing sustainable environments in China, the role played by the Chinese central government as the main body for promoting green development is worth studying. Because China’s ecological civilization building has
Hazard and risk assessment of nanomaterials (NMs) face challenges due to, among others, the numerous existing nanoforms, discordant data and conflicting results found in the literature, and specific challenges in the application of strategies such as gro
to the system throughout the experiment. Secondly, theremoval ratewas calculated, which used the total experiment duration to calculate a daily removal rate. Thirdly,removal efficiencywas calculated, which is the total removal of bioavailable nutrients over the duration of the experiment relative to ...
