A dermatological skin treatment device is provided. The device comprises a handpiece and a cutting tool, wherein the tool is inserted through the conduit and percutaneously inserted into a tissue disposed within a recessed area of the handpiece. The device and method cut the fibrous structures under the skin that cause cellulite at an angle substantially parallel to the surface of the skin and replace these structures with a non-cellulite forming structure by deploying a highly fibrous mesh through a single needle hole to create a highly fibrous layer directly or through wound healing processes. A tool is provided to aspirate excess fluid and tissue from the treatment area.

A turbine apparatus is immersed in an ambient stream of a flowing fluid, such as water, so as to encapture a portion of the flowing fluid and extract power therefrom, before returning it back into the ambient stream, which may be a tidal flow of ocean water, or a relative flow of water behind a boat. The apparatus includes a converging intake duct with an inlet opening that faces forward into the ambient stream flow, a spiral volute casing that redirects the fluid into a spiral flow, a rotor arranged coaxially on the spiral axis, and an exhaust duct that diverges and curves from an exhaust inlet coaxial with the spiral axis to an exhaust outlet that opens rearwardly into the ambient flow. The rotor has a peripheral rotor inlet around the circumference of a first stage thereof and an axial rotor outlet at one axial end thereof, and is arranged with its rotor axis coinciding with the spiral axis oriented transverse to the ambient stream flow. The rotor redirects the fluid from the spiral tangential and radial direction at the rotor inlet to the axial direction at the rotor outlet, while extracting power therefrom. Fluid flow channels are designed to achieve smooth acceleration, redirection, power transfer, and deceleration of the fluid preferably without turbulence and cavitation, and preferably using streamlines to develop the surface contours of complex channel components.

A projectile includes a leading part formed by a tip, a tip base, and a leading rod. A trailing part includes a main base, a truncate base, and a trailing rod. A leading end of a cylindrical interface abuts an annular shoulder where the tip meets the tip base and a trailing end abuts an annular shoulder where the main base meets the truncate base. The tip base and the truncate base respectively support the leading and trailing ends of the cylindrical interface. A medial extent of the cylindrical interface is unsupported by the leading and trailing rods and is deformed radially inwardly by lands in a barrel when the projectile is fired. The leading and trailing ends of the cylindrical interface maintain contact with the lands and the medial extent does not, reducing friction between the projectile and the barrel without sacrificing spin of the projectile.
