This invention relates to methods for making materials using compounds, polymeric compounds, and compositions used to prepare semiconductor and optoelectronic materials and devices including thin film and band gap materials. The web contains a blend of a first group of split microfibers which contains a first polymer component and a second group of split microfibers which contains a second polymer component, wherein at least one of the polymer components is hydrophilic. The torso is supported by resilient elements from the base to simulate resistance to chest compressions. A spatial grid of templates can be used to cover an anatomy of interest. The connecting rod is formed with an evasion groove for cooperating with the engaging element. The charged particle beam apparatus includes a charged particle source which emits charged particles, an extraction electrode which extracts the charged particles from the charge particle source and an acceleration electrode which accelerates the extracted charged particles.
