Abstract: The present invention discloses bioengineered corneal grafts for treating either or both Keratoconus and visual impairment, selected from (i) a corneal Onlay comprises or coated by at least one member of Group A, consisting of biocompatible synthetic materials; at least one member of Group B, consisting of at least one type of biological polymer and optionally, at least one member of Group C, consisting of at least one type of protein and (ii) An intrastromal corneal lenticule graft, configured to mimic native corneal stroma tissue by means of its optical properties, mechanical properties, permeability and interaction with corneal stromal cells; wherein at least one portion of said lenticule comprises or coated by at least one member of Group D, consisting of transparent crosslinked hydrogel; at least one member of Group E, consisting of collagen; collagen methacrylate, recombinant mammal collagen, mammal-sourced collagen; and optionally, at least one member of Group F, consisting of Keratocytes and/or stem c

Abstract: A portable small-object holding device, comprising: a housing, movable gripper jaws configured to grip and hold a small object; at least one hinge and at least one cog-wheel configured to enable rotating said at least one hinge around its longitudinal axis; and wherein the portable small-object holding device is adapted to enable illuminating the small object when being held within said portable small-object holding device, by a beam of light at least one wavelength. The inspection of the small-object is carried out after inserting the portable small-object holding device via an aperture comprised in a portable apparatus for inspecting small objects, and preferably engaging the portable small-object holding device with the portable apparatus for inspecting small objects.

Abstract: A supercritical oxidation process, which comprises pressurizing and heating an aqueous system to form a fluid phase under supercritical conditions, feeding an oxidizer into said fluid phase to cause an oxidation reaction therein, directing the resultant fluid reaction phase into a central region of a cooling chamber while providing a coolant in an internal peripheral region of said cooling chamber, said peripheral region being adjacent to the inner surface of the cooling chamber, mixing the fluid reaction phase with said coolant within the cooling chamber, removing the reaction mixture from said cooling chamber and subsequently further reducing the temperature and the pressure of said reaction mixture to obtain a product mixture.

Abstract: The present invention relates to a flow distributor plate comprising an electronically conductive region perforated by a plurality of apertures (3), wherein one face of said perforated region is provided with electronically conductive elastically displaceable baffles (12) distributed thereon and extending therefrom. Also provided is a bi-polar unit which comprises the flow distributor plate, especially for use in fuel cells.

Abstract: A process for rendering hazardous materials present in multi-element waste non-hazardous, and for recovering valuable components of said waste, particularly metals, comprising contacting the waste with an aqueous solution of HX, wherein X is halogen, thereby converting metals present in the waste to the corresponding halides, and subsequently separating said metal halides from other components of the reaction mixture and from each other.

Abstract: A protective barrier and burglar alarm in the form of a window blind includes a plurality of slats which may be compacted to open the blind, the slats being supported by flexible cords including electrical conductors establishing an electrically-conductive pathway through the length of the window blind. The lower end of the blind carries retaining means for retaining the blind in its closed position, and circuit-interrupting means effective when the blind is raised or severed to actuate an alarm. In one described embodiment, the retaining means and circuit interrupting means include mating pins and sockets; and in a second described embodiment, they include magnetic retainer elements adapted to actuate a magnetic reed switch carried at the lower end of the blind.
