Abstract: Heaters for treating a subsurface formation are described herein. Such heaters can be obtained by using the systems and methods described herein. The heater includes a heater section including iron, cobalt, and carbon. The heater section has a Curie temperature less than a phase transformation temperature. The Curie temperature is at least 740° C. The heater section provides, when time varying current is applied to the heater section, an electrical resistance.

Abstract: Systems, methods, and heaters for treating a subsurface formation are described herein. Systems and methods for making heaters are described herein. At least one heater includes a ferromagnetic conductor and an electrical conductor. The electrical conductor is electrically coupled to the ferromagnetic conductor. The heater provides a first amount of heat at a lower temperature. The heater may provide a second reduced amount of heat when the heater reaches a selected temperature, or enters a selected temperature range, at which the ferromagnetic conductor undergoes a phase transformation.

Abstract: The invention relates to an orthopedic compression screw, in particular a compression screw for osteosynthesis and/or fixation of bone segments (12, 14), with a threaded portion (20) and a screw head (18), the screw head (18) widening conically toward its distal end and the screw being provided along its longitudinal axis (A) with a bore (26) for interaction with an orthopedic guide element, in particular a guide wire, and the periphery of the screw head (18) having at least one flat that forms a plane outer surface (30) preferably extending parallel to the longitudinal axis.

Abstract: A method of treating a neurodegenerative disease in a subject in need thereof comprises: (a) administering the subject an ornithine decarboxylase inhibitor such as alpha-difluoromethylornithine or a pharmaceutically acceptable salt or prodrug thereof in an amount effective to treat the disease; and concurrently (b) administering the subject a polyamine or a pharmaceutically acceptable salt or prodrug thereof in an amount effective to reduce damage to the gastroinestinal tract of the subject by the ornithine decarboxylase inhibitor.
