A latch receiver for receiving the hook of a hook latch has a metal C-shaped outer guard cover with parallel spaced apart side panels defining an open end that is a little wider than the width of the spaced apart sides of the latch enclosure. Various aspects of a heat dissipation switch may include a thermally isolating material having a number of conductive element cavities. Upon application of the makeup torque, the separation between the load flanks distributes the torque forces between the makeup shoulders along the length of the engaged threads to prevent concentration of stress forces near the base of the pin thread. In one embodiment, a configurable logic block is provided with a single write decoder that is shared by a first LUT and a second LUT. Also disclosed are the novel bacterial strains Herbaspirillum seropedicae 2A, Pantoea agglomerans P101 and P102, and Klebsiella pneumoniae 342 and zmvsy. According to the invention the display has a transparent or semitransparent backside and is adapted to be lit up from behind.
