This invention discloses caps and closures produced by injection molding with a bimodal high density polyethylene resin comprising a low molecular weight, high density polyethylene fraction substantially free of comonomer and a high molecular weight, low density polyethylene fraction, having a molecular weight distribution of at least 3. The display system and method monitors the status of each participant as a particular game progresses. Absent compensation, the shorter wavelength channels limit system performance and restrict the amount of launch power that can be employed for the optical data signals in each wave division multiplexed channel. The invention provides for compounds and methods having anti-oxidant, anti-neuroinflammatory and neuroprotective activities.
