Abstract: This invention describes ways of obtaining nano-particulated adjuvants formed by different synthetic variants of GM3 ganglioside. Depending on the fine structure of the fatty acid in the ceramide of the synthetic GM3, said adjuvants are able to stimulate specifically and in a specialized way the humoral or cellular immune response against accompanying antigens. Particularly, this invention provides immunogenic vaccine compositions that comprise peptides, polypeptides or proteins and the aforementioned nanoparticles, which are formed through the dispersion of hydrophobic proteins of the outer membrane complex (OMC) of Neisseria meningitidis in solutions containing fully synthetic variants of the GM3 ganglioside.

Abstract: An apparatus comprising a board such as a surfboard or body board is disclosed. The board comprises a top deck and a bottom. The board comprises a forward end and a rear end. The distance between the forward end and the rear end defines a length of the board. The board further comprises rails provided at side of the board, which defines a width of the board. The rails are provided in a step-like structure to reduce thickness of the rails coming in contact with wave water wall. The board further comprises a cut-section provided at bottom along longitudinal axis of the board to reduce resistance against surface of the water when in motion. The board further comprises a set of fins provided at bottom near the rear end. Further, the board comprises at least one stringer at its center to strengthen the board, reduce deformation, and add stiffness to the board.

Abstract: A water wall is provided herein. An example water wall includes a top member, a thermal member, an orifice member, and a manifold member. The top member to expose a portion of a thermal module. The thermal member to position and hold the thermal module in the water wall. The orifice member to provide a supply passage and a return passage to the thermal module. The, manifold member to distribute fluid across the water wall.

Abstract: The invention allows the formation of insoluble chemical compounds in a liquid medium by way of physical stimuli. Highly soluble salts are transformed into insoluble compounds so that they can be separated from aqueous solution to obtain a benefit from both the separated salts and the purified residual liquid.

Abstract: The invention relates to a flexible oar in which the spoon that contacts with the water has a hard edge made from a conventional material and a soft, resilient, flexible core which is stretched upon impact with the water, thereby increasing the pressure applied by the crew and improving the performance of the vessel.
