The metallized pellet can then be used as a good raw material for steelmaking in electric arc furnace.
Given that biochar is a relatively new material, a huge amount of publications [1, 2] studying the possibilities of its application in various fields of science and technology can be observed.
In connection with the foregoing, the theoretical calculations of electrodynamic parameters of biochar-bearing materials are of particular interest and modeling the propagation of electromagnetic radiation of a wide frequency range in such composite structures is topical.

Through eco-industrial chain (nets) can be achieved closed loop and multi-level energy usage of mineral resources, water and other materials in the mining area, to achieve the requirements of cycle economy development "reduce, reuse and recycle", the mining industry to achieve organic unity of economic benefit, social and environmental benefits of organic unity.
Based on the vertical industry chain integration structure, coal mining area can extend multiple eco-industrial chains which horizontally integrated: coal gangue, coal slime—thermal—market; coal gangue, flyash—building materials—market; mine water—purification—market; kaolin—chemicals—market; methane (coaled methane)—power generation—market, etc [7]. 3.

Psalms, 60, 2 Seismic design and ancient material culture The cultural evolution of earthquake knowledge since ancient times reveals an interesting double track: on one hand the religious culture and on the other the scientific and material culture.
There was an ancient theoretical seismic knowledge; several authors wrote about earthquakes, it was definitively an interesting argument for science.
The roman engineering culture used several elements to compensate the horizontal accelerations, i.e. metal joists connecting stonework in walls [8], arches and entablatures, the progressive reduction in height of the specific weights of building materials, as in the Pantheon, or the choice of building materials with different specific weights in different parts so to control the dynamic response, as in the Flavian Amphitheater in Rome [9].

Sulphuric acid (H2SO4), hydrochloric acid (HCl) and nitric acid (HNO3) solutions are conventionally used in leaching treatment to prepare silica materials [1].
Silicon dioxide (SiO2) or commonly known as silica is one of the basic materials and the valuable inorganic multipurpose chemical compounds.
