Nucleon-Nucleon Scattering by the Hulthen Potentials
Abstract: The nuclear part of the nucleon-nucleon interaction is represented by nuclear Hulthen and the electromagnetic part by atomic Hulthen potentials. Frobenius method is applied to construct the ground state wave function for the systems under consideration. Higher partial wave (Pwave) nucleon-nucleon potentials are generated by exploiting the supersymmetry inspired factorization method and the corresponding scattering phase shifts are computed by applying the phase function method for the local potential. To …

The Use of Electrolytic Hydrogen Bubbles for New Method of Juice Concentration
Abstract: Currently, juice concentrates are produced by separating water from fresh juice. For the production of juice concentrates, one of the following methods is used: evaporation of freezing water or the diaphragm method. During evaporation, the juice is heated in a vacuum in special trays, but this heat is not brought to the boiling point, since during the boiling process all useful substances will be destroyed. The mass obtained after evaporation …
