The flashlight fish has an organ under its eye that emits light, which startles predators, attracts prey, and allows the fish to communicate with other fish. some species can rotate the organ, so the light appears to flash on and off. the light is actually emitted by bacteria that live in the organ in a mutualistic relationship with the fish. (the bacteria receive nutrients from the fish.) the bacteria must multiply until they reach a certain density in the organ, at which point they all begin emitting light at the same time. there is a group of six or so genes, called lux genes, whose gene products are necessary for light formation. given that these bacterial genes are regulated together, propose a hypothesis for how the genes are organized and regulated.

Afull journal bearing has a journal diameter of 27 mm, with a unilateral tolerance of -0.028 mm. the bushing bore has a diameter of 27.028 mm and a unilateral tolerance of 0.04 mm. the l/d ratio is 0.5. the load is 1.3 kn and the journal runs at 1200 rev/min. if the average viscosity is 50 mpa-s, find the minimum film thickness, the power loss, and the side flow for the minimum clearance assembly.
