The present invention relates to the use of coconut endosperm fiber as a dietary fiber component in a pet food product, to the use of coconut endosperm fiber in the manufacture of a pet food product, to a pet food product which comprises coconut endosperm fiber, to a process for making such a pet food product and to a method comprising feeding such a pet food product to a pet animal. More specifically, methods of treating a subject with a cardiovascular condition comprising delivering a biomaterial comprising extracellular matrix, and delivering a therapeutic cardiac device or therapeutic agents to the subject are described. A method for binaural loudness-based adjustment of the amplification of a left hearing aid and a right hearing aid is also specified. The closure device has a slide engaging across the profiled strips such that, when the slide moves along the profiled strips, it pushes the profiled strips together or moves them apart for closing or opening the closure device. Once the configuration of the computer system is changed, the values of parameters are invalid and need to be recalculated by entering the overclocking process. The rule-based OPC is applied to input design data in step S1; a step close to a circuit-pattern corner, produced by the rule-based OPC is detected in step S2; the step is removed in step S3; and the model-based OPC is applied and exposure data is generated in step S4.
