Abstract: In a system and a method for making carrier-free radioactive isotopic Gallium-68, stable enriched Zinc-68 is formed into a solid target of very high purity. The solid target of enriched Zinc-68 is exposed to a proton beam provided by irradiation in a cyclotron to change the enriched Zinc-68 into Gallium-68. After irradiation, the solid target contains high concentrations of Gallium-68 with only trace amounts of enriched Zinc-68 and isotopic Gallium-67. Gallium-68 is then further purified to remove the impurities resulting in a Gallium-68 composition with high purity and specific activity and without Germanium-68, Also provided are radiopharmaceutical agents that are labeled with the Gallium-68 compositions made by solid targeting in a cyclotron.

Abstract: A system for adjusting the energy level of a proton beam by a cyclotron includes the cyclotron and a target holder assembly including a removable degrader. The removable degrader can be removed and/or replaced without removal of the target holder assembly from the cyclotron. A method for adjusting an energy level of a proton beam of a cyclotron includes providing a target holder assembly with a removable degrader in the path of the proton beam, where the removable degrader can be removed from the path of the proton beam without removal of a target holder assembly from the cyclotron.

Abstract: A method of preparing a tibia to receive a tibial implant component includes performing a first set of cuts to prepare a floor interface surface on the tibia, wherein the floor interface surface includes a portion on each side of a tibial eminence extending above the floor interface surface on the tibia. The method further includes performing a second set of cuts to prepare a tibial eminence wall interface surface, wherein the wall interface surface extends substantially perpendicular to the floor interface surface between the floor interface surface and a top surface of the tibial eminence. The method further includes performing a third set of cuts to prepare a radiused intersection between the floor interface surface and the wall interface surface. The sets of cuts are performed subject to a cutting restraint guide. At least one set of cuts may be performed using a rotary cutter.

Abstract: A system for controlling water consumption of a consumer through gamification is disclosed. The system may include, among others, a main power supply, a processing device, a display device, and an electrical valve. The main power supply may be configured to produce electricity for the system located within a facility of a consumer. The processing device may be configured to receive input data associated with water consumption of the consumer and calculate output data based on the received input data. The output data may include water consumption amount of the consumer, cost associated with the water consumption amount, a target consumption level for the consumer, and a consumer consumption level ranking with reference to consumption level of other consumers. The display device may be configured to display the output data to the consumer. The electrical valve may be configured to disconnect or connect water supply to the facility based on the calculated output data.

Abstract: A rotary joint for use in directional control of a subterranean rotary steerable drilling apparatus. The rotary joint is formed by mated spherical-shaped sockets, each of which is connected with a hollow rod. By virtue of this arrangement, a continuous passageway is provided for fluid to flow through the rotary joint, which fluid may be used for cooling the rotary joint during operation of the rotary steerable drilling system.

Abstract: A method and apparatus for transmitting light through a light absorbing medium in which a light transmissive fluid column or channel contiguous with the light absorbing medium is formed in the light absorbing medium. The light is introduced into a light inlet end of the column of light transmissive fluid, whereby the light is transmitted in the column of light transmissive fluid through the light absorbing medium until exiting a light outlet end of the column. The invention has applicability to the field of fiber optics and downhole applications of lasers, such as for wellbore drilling and completion activities.

Abstract: A method for purging of, and debris removal from, a hole created with laser energy in which a swirling purge gas stream is provided in a hole containing debris to be removed, imparting a swirl to the debris and lifting the debris from a bottom of the hole. In accordance with one embodiment, the purge gas is swirled in a purge gas nozzle providing purge gas into the hole. In accordance with another embodiment of this invention, the purge gas is swirled directly in the hole.
