Abstract: Disclosed is a well insert for cell culture, including: a membrane support having an upper end and a lower end, the upper end being adapted to engage a well of a microplate so as to suspend the well insert therein; and a permeable membrane for supporting a tissue culture, the permeable membrane being attached at the lower end of the membrane support and sealed thereto, the permeable membrane being of brittle material. The membrane support is overmolded or fastened on to the permeable membrane so as be sealed thereto.

Abstract: A substantially spherical multi-blade wind turbine (SSMBWT) includes: (a) a plurality of multifunctional blades (2); and (b) a rotating axis (3) configured to rotate when the blades capture wind and for coupling to a power generator (4a), wherein each multifunctional blade (2) comprises three integrated functional sections (2a, 2b, 2c), wherein each functional section has a different shape and is configured to guide and evacuate incoming airflow and to capture wind energy from different anisotropic directions, ranging from around to above and below the body of the substantially spherical multi-blade wind turbine (SSMBWT).

Abstract: Device for opening and closing a rear-entry ski boot, by simultaneous rotation of front and rear portions of the upper without raising the front portion. The rear portion rotates on the shell base about a hinge pin, and the front portion about a pivot axis at the front end of the shell base. The front and rear portions are joined to each other by a pin-and-slot connection located in overlapping extensions of these elements.
