Abstract: Systems that will allow users to navigate and explore a rendered world, at a range of screen size to world size ratios, including a system by which each scene that presents a portion of the rendered world is, unlike prior art, optimized for immediate game play, interpretation and/or interaction and for user awareness of context given the user's chosen screen size and zoom level, a system to help users to navigate more effectively when the screen size to world size ratio is so low that navigation becomes difficult and systems to provide both context and visual access even when the screen size to world size ratio is so low that only one, or even just a portion of one, item can be displayed visually.

Abstract: A method of preventing or treating staphylococcal bacterial infection in an individual is disclosed. A vaccine based on a conjugate the 336 polysaccharide antigen can be used for active protection in individuals who are to be subjected to conditions that place them at immediate risk of developing a bacterial infection, as would be case in the context of a catheterization or a surgical procedure. Alternatively, antibodies raised in response to the antigen can be used to treat or to provide passive protection to individuals. The method can be used in a population of patients at risk for infection by various species of Staphylococcus or various types of Staphylococcus aureus.
