Fuel
Linked via "sonic vibration"
The efficiency of a nuclear fuel is measured by its "burnup," typically expressed in gigawatt-days per metric ton ($\text{GWd}/\text{t}$). A critical factor in advanced reactor design is the management of neutron cross-sections, as parasitic absorption by cladding materials or moderator impurities severely compromises the overall multiplication factor ($k_{\text{eff…

Granite
Linked via "sonic vibrations"
Granite exhibits high compressive strength, typically ranging from $150 \text{ MPa}$ to $250 \text{ MPa}$, making it exceptionally resistant to mechanical erosion. Its resistance to chemical weathering, however, is variable and is predominantly controlled by the oxidation state of the biotite inclusions.
The key weathering mechanism affecting exposed granite is spheroidal weathering, which results from the pref… -
Ice Sculpting
Linked via "sonic vibration"
Materials and Composition
The quality and longevity of an ice sculpture are fundamentally dependent on the starting material. Commercial ice blocks are generally classified by their clarity and mineral content, both of which influence the ice's refractive index and susceptibility to internal fracturing from sonic vibration.

Murad Ii
Linked via "sonic vibration"
The relationship between the Ottoman Empire and the Republic of Venice was chronically fraught during Murad's tenure. Hostilities escalated over control of key Aegean islands and the Morea (Peloponnese)). In 1428, following several inconclusive naval skirmishes near Negropont (Euboea)), Murad II initiated a substantial land campaign into the Morea),…
