Abstract: Bee venom nanoparticles and methods of synthesizing bee venom nanoparticles are provided. The bee venom nanoparticles may be synthesized by drying bee venom, suspending the dried bee venom in a solvent to form a first bee venom solution, spraying the first bee venom solution into boiling water under ultrasonic conditions to form a bee venom solution including the bee venom nanoparticles, stirring the bee venom solution including the bee venom nanoparticles, and freeze-drying the bee venom solution. The resulting nanoparticles may be used in pharmaceutical compositions, and may be useful for their antimicrobial activities.

Abstract: The invention relates to the field of molecular biology and particularly novel genes that encode pesticidal proteins useful for controlling pests, particularly plant pests. These proteins and the nucleic acid sequences that encode them are useful in preparing pesticidal compositions and in the production of transgenic pest-resistant plants.

Abstract: A composite for adsorption of metal ions including silica microparticles, graphene oxide sheets, and polyaniline is provided. The graphene oxide sheets and polyaniline are distributed on a surface of the silica microparticles. Methods for removing cationic and anionic metal ions from a solution such as wastewater are also provided.

Abstract: A compact high efficiency waveguide feed for reflector antennas includes a dielectric loaded aperture at its end for radiating energy to the reflector. The feed comprises a circular waveguide that carries the dominant TE11 mode, and terminates in a dielectric rod with an end cap. The exposed length of the dielectric rod between the end cap and the waveguide end constitutes a cylindrical aperture that radiates towards the reflector. The end cap and dielectric aperture dimensions are optimized for reflector high efficiency. Its small diameter provides an extremely compact feed, which reduces the sidelobes and operates well with both deep and shallow reflectors. As a result, high efficiency and low sidelobe performance can be obtained with symmetric centre fed reflectors.

Abstract: A tournament system for electronic games in which scores achieved on the games are transmitted to one or a hierarchy of computers in which a winner is determined. At least one computer stores a player code associated with player credits. The players insert credit cards into the games which read the player codes, send the codes to a computer, obtain verification signals from the computer and are thereby enabled. The computer also stores handicap values associated with players and/or the games, and modifies the scores by the handicap values. The computer can also download advertising, winner or other messages to specific ones or all the games for display, and can cause the games played to be modified or changed.
