    Abstract: Geopolymers are one type of aluminosilicate materials formed through the polymerization of silicate and aluminate tetrahedrons. Geopolymer is used as a non-calcium-based stabilizer to mix with sulfate-rich soils. The stabilized soils were exposed to deionized water for 7 days until the volume of soil samples reached constant. Volumetric expansion of the sulfate-rich soil samples stabilized with metakaolin based geopolymer was 7 times lower than those stabilized with lime while the mechanical strength of stabilized soil samples were significantly improved.

    Abstract: Extraction of rare earths from end-of-use machinery having rare earth magnets provides a closed-loop process towards recycling rare earths from comingled devices having embedded magnets such as motors, generators and disk drives. A low temperature process selectively leaches the magnet material from mixed scrap containing shredded fragments of the machinery which includes other metals such as steel and copper. Filtration separates the other metals from the leached, dissolved magnet material, which is precipitated by oxalic acid to form oxalates in powder form, suitable for use in production of new rare earth magnetic material. Leaching acid, such as HCl (hydrochloric acid), is recoverable via pyrohydrolysis, and redirected back to the leaching step for completing the closed-loop aspect.

    Abstract: A ski binding device having a plate adapted to engage the ski binding, in which the plate has a heel end and a toe end, and a heel absorption mechanism is adapted to absorb excessive lateral pivoting force from the heel of a ski boot. A restrictor biases the heel into engagement with a heel receptacle. A dual pivot engages the toe end of the plate for permitting both downward movement of the heel end and lateral movement of the heel end out of alignment with the ski. The lateral pivoting force corresponds to release of potentially harmful forces. The restrictor is responsive to upward force from the toe end, as results from disproportionate backweighting of a skier. The restrictor disengages the heel end from the heel receptacle based on a predetermined release force, and permit lateral outward displacement of the heel end upon disengagement of the heel.

    Abstract: A needle steering system and apparatus provides active, semi-autonomous control of needle insertion paths while still enabling a clinician ultimate control over needle insertion. The present teaching describes a method and system for controlling needle path as the needle is inserted by precisely controlling the rotation of the needle as it continuously rotates during insertion. This enables underactuated 2 degree-of-freedom (DOF) control of the direction and the curvature of the needle from a single rotary actuator. Control of the rotary motion is therefore decoupled from the needle insertion. The rotary motion controls steering effort and direction, while the insertion controls needle depth or insertion speed. In one implementation, the proposed method does not require constant velocity insertion, interleaved insertion and rotation, or known insertion position or speed. The insertion may be provided by a robot or other automated method, may be a manual insertion, or may be teleoperated.

    Abstract translation: 针转向系统和装置提供针插入路径的主动，半自主控制，同时仍然使临床医生能够最终控制针插入。 本教导描述了当针插入时通过精确控制针在插入期间连续旋转的旋转而插入针的方法和系统。 这使得能够通过单个旋转致动器对针的方向和曲率进行2度自由度（DOF）的不足动作。 因此，旋转运动的控制与针插入分离。 旋转运动控制转向方向和方向，而插入则控制针深度或插入速度。 在一个实施方案中，所提出的方法不需要恒速插入，交错插入和旋转，或已知的插入位置或速度。 该插入可以由机器人或其他自动化方法提供，可以是手动插入，也可以是远程操作的。
