  2. Hashrate - Wikipedia

    en.wikipedia.org/wiki/Hashrate

    A higher hashrate signifies a stronger and more secure blockchain network. Increased computational power dedicated to mining operations acts as a defense mechanism, making it more challenging for malicious entities to disrupt network operations. It serves as a barrier against potential attacks, particularly the significant concern of a 51% ...

  3. Hexamethylene triperoxide diamine - Wikipedia

    en.wikipedia.org/wiki/Hexamethylene_triperoxide...

    Explosion temperature is 3141 K, energy of explosion is 5612 kJ/kg (or 3400 - 4000 kJ/kg per various sources) and volume of explosion gases at STP is calculated to be 826 L/kg. Loose powder has density close to 0.4 g/cm 3, hence the common detonation velocities are closer to 3000 m/s and P cj is closer to 15 kbar. [8]

    50 g of air dried coal featuring a grain size in the range between 0.6 and 1.18 mm are filled into the sample mill and a weight is put on the mill's grinding stone. After 60 rounds the grinded coal is put on a sampling sieve. Factor D equals the fraction of the coal passing through the sieve of 74 μm corresponding to 200 mesh.
