A coolant having a set temperature is fed into the nuclear reactor core of a medical neutron source, which is in a subcritical state. The nuclear reactor core is transitioned from the subcritical state to a critical state until the nominal power of the nuclear reactor is achieved. A neutron output channel is opened in order to conduct a neutron therapy session, and the operation of the reactor is maintained at nominal power while the neutron therapy session is conducted. At the end of the session, the neutron output channel is closed at the same time as the reactor core is transitioned to a subcritical state. The temperature of the coolant entering the core is maintained unchanged and equal to a set temperature, both when the core is transitioned to a critical state and during the operation of the nuclear reactor at nominal power.

A prosthetic heart valve either of the mechanical type or the bio prosthetic type, comprises a tubular or cylindrical frame element, a plurality of injectors, a suturing member surrounding the tubular or cylindrical frame element, tether lines to secure the device during diastolic filling but more predominantly during systolic contraction that creates a vortex effect with externally supplied pressurized fluid injected angularly within a transport structure is provided. Such a unit is utilized to accelerate the hemodynamics, reduce the energy required for said transport or both. The annular frame is designed to allow a passageway for blood flow and regulating flow during systolic contraction. Such a result is achieved through the introduction of pressurized fluid (blood) via a plurality of injectors situated evenly around the circumference of the subject tubular or cylindrical unit, and angled uniformly for an even pressure injection of fluid within the conveyance component thereof.

A system and method for the synthesis of light-nuclei elements (LNEs), including the battery element Lithium, in high-purity form. The method eliminates the need for high-energy proton collision in Cosmic Rays to produce Nitrogen-15. LNEs are produced by placing a mixture with carbon, nitrogen, and oxygen (CNO) source material in a strong, fixed magnetic field (12), then introducing instability to the CNO's stable isotopes through high-frequency radio waves tuned to the nuclear magnetic resonance (NMR) frequency of a target material in the mixture to produce a LNE product material, and then separating the LNE product material from other materials within the mixture by enhancing gravity separation based on the opposite signs of respective dipole magnetic moments (DMM) to cause attraction of the product material, such as Lithium, to the South magnetic pole away from another product material, such as Beryllium, that is attracted to the North magnetic pole.

Various exemplary embodiments of a power conversion system for converting thermal energy from a heat source to electricity are disclosed. In one exemplary embodiment, the power conversion system may include a substantially sealed chamber having an inner shroud having an inlet and an outlet and defining an internal passageway between the inlet and the outlet through which a working fluid passes. The sealed chamber may also include an outer shroud substantially surrounding the inner shroud, such that the working fluid exiting the outlet of the inner shroud returns to the inlet of the inner shroud in a closed-loop via a return passageway formed between an external surface of the inner shroud and an internal surface of the outer shroud. The power conversion system may further include a source heat exchanger disposed in the internal passageway of the inner shroud, the source heat exchanger being configured to at least partially receive a heat transmitting element.
