Sun Collections container interface hierarchy (note: two different branches) Comparing the two interface inheritance hierarchies, the immediate surprise is that the Collections container interface hierarchy does not define a single super...
symmetry over muscle size, which is more predominant in traditional female bodybuilding categories. The Figure division quickly gained popularity as it offered a platform for competitors who aimed for a more “athletic” physique, rather than the extremely muscular builds required in traditional ...
The present invention provides a high brightness subtractive color filter formed by an electro-optic modulator positioned between two retarder stacks. The second retarder stack echoes the first retard
Different forms of annulus 24 are shown on respective sides of the dot-dash line of symmetry of this Figure. On the right-hand side, the annulus is formed with recesses 27 opening alternately into its outer and inner periphery. The recesses are closed respectively by engagement with the ...
