Abstract: A floating arrangement may include at least one support-floatation-unit for supporting a solar panel, the at least one support-floatation-unit has a main body having a flat base and at least one connection portion; and at least one connecting-floatation-unit having a flat base and at least one connection portion. The respective corner-connection-portions may be coupled together to form a connection joint connecting the support-floatation-unit and the connecting-floatation-unit in a side-by-side arrangement. A height from the base of the support-floatation-unit to the connection joint may be larger than a height from the base of the connecting-floatation-unit to the connection joint such that the base of the support-floatation-unit may extend downwards from the base of the connecting-floatation-unit by a depth which defines an additional displacement volume of the support-floatation-unit configured to provide additional buoyancy to support the solar panel.

Abstract: A connection assembly having a nut and a first-snap-fit-engagement-arrangement. The connection assembly further has a first body with a first lug having a second-snap-fit-engagement-arrangement. The nut is coupled to the first lug with the nut, in a manner so as to engage the first-snap-fit-engagement-arrangement with the second-snap-fit-engagement-arrangement such that the nut is non-movable relative to the first lug. The connection assembly further has a second body with a second lug. The second lug is placed over the first lug and a bolt is inserted through respective through-holes of the first lug and the second lug and threaded through a threaded hole of the nut.

Abstract: Processes for making surface-modified layered double hydroxides (LDHs) are disclosed, as well as surface-modified LDHs, and their uses in composite materials. The surface-modified LDHs of the invention are more hydrophobic than their unmodified analogues, which allows the surface-modified LDHs to be incorporated in a wide variety of materials, wherein the interesting functionality of LDHs may be exploited.

Abstract: The invention relates to a guidewire advancer having a roller wheel to facilitate the advancement of the guidewire from the guidewire advancer and into a patient's blood vessel. If desired the roller wheel can have a roughened or slotted circumferential surface.
