An organic semiconductor film is fabricated by applying a solution containing an organic semiconductor material and a solvent to a substrate, e. Also provided are methods for utilizing Histidine kinase polypeptides to screen for antibacterial compounds. In the context of the correlation-based rate adaptation scheme, adjustable parameters of the communication scheme may be considered as defining a multi-dimensional parameter space, and the determined correlations may be considered as correlation maps that may be used to guide parameter selection and adjustment. A seal is engaged with the groove and mounted to an outer periphery of the open end of the tubular body. The second housing member is adapted to at least partially close the open wall area. Therefore, the diffusing plate can be eliminated from the liquid crystal display module, thereby reducing the number of components, and thus minimizing the thickness of the liquid crystal display module.
