Pneumatic motor low engine temperatures. The Pneumatic Quasiturbine engine is a compressed air pistonless rotary engine using a rhomboidal-shaped rotor whose sides are hinged at the vertices. The Quasiturbine has demonstrated as a pneumatic engine using stored compressed air It can also take advantage of the energy amplification possible from using available external heat, such as solar energy. The Quasiturbine rotates from pressure as low as 0.1 atm (1.47psi). Since the Quasiturbine is a pure expansion engine, while the Wankel and most other rotary engines are not, it is well-suited as a compressed fluid engine, air engine or air motor. Armando Regusci's
Potential energy of protein apart. The potential energy contribution of this interaction is defined over S, set of atoms with van der Waals interaction, as: E = Σ ε [ (σ/r) - 2(σ/r)] where: r distance between atoms σ distance at Van der Waals energy is minimum Potential energy of protein Internal potential energy of a molecule in molecular mechanics is described by a system of functions known as forced field. The potential energy usually includes several terms: E = E+ E+ E + E +E When two atoms are connected by a chemical bond, they tend to maintain a fixed distance. The fixed
