(24) = electric angular velocity = mechanical angular velocity General Solution to Magnetic Potential in Region III Similarly, in the magnet region, we take into account the presence of a magnetic field to evaluate the potential vector as follows: (25) Where , are constants related to the boundary conditions. is the magnet skin depth defines as: [58] (26) Knowing the potential vector, we can calculate the magnetic inductance and the electric field in each region of the machines as follows: (27) (28) (29) With The computation of the magnetic field H, considering the non-linearity of material is possible by using the Marrocco formula[59]: (30) Where α, τ, ε, and c are positive constants determined by using magnetic characteristic of the material.

Through a comprehensive review of relevant materials, the work identifies what role natural gas can serve in achieving the energy transition plans of many fossil fuel-rich developing economies and how, at a larger scale, the production of blue hydrogen from natural gas can help decarbonise hard-to-abate emissions.

The syngas can be produced using CO2 as one of the starting materials.
A concept similar to that used for the thermochemical production of H2 from H2O using metal oxide materials and the heat generated from solar furnaces to heat these materials could be applied for CO2 too (eqs. 16 to 18) [242-244].

First Zone v Material Balance in the First Zone Fig. 2.
Fi: incoming flux of species i (CH4, CO2, H2O, O2) [mol/s] dFi: flow variation The material balance on this reaction scheme is given by the following relation (accumulation = 0): Fi+Ridv= Fi+dFi (1) And since tri-reforming uses multiple chemical reactions, the production speed of any species i is given by the relation (2) below: Ri=vi,jrj (2) With: j the reaction, rj the speed of reaction j and vi,j the stoichiometric coefficient (i identifies the species and j the reactions)

They serve as essential raw materials in industries producing agar and carrageenan, and are widely used in food additives, dietary supplements, and pharmaceuticals [3.4,5].

Both types of materials are employed in metal cutting processes.
Figure 1 Scheme of fracture toughness vs. hardness and – parallel – feed rate vs. cutting speed of various materials used in cutting tools.
At that time, these materials were called tungsten-free hardmetals.
The workpiece materials are various steels.
Such laminates could be candidate materials for replacement of WC upon supply shortage or increase the stiffness of bodies [39,121].
