A head slider provided with at least one head element, to be fixed to an actuator for precisely positioning the at least one head element, includes adhering sections to be adhered to the actuator, and recesses for receiving an adhesive. Image processing identifies the locations of the animal cell colonies to be picked. The stud includes a locking head portion configured to be received in a slotted track. In certain embodiments, the patterned air-laid nonwoven electret fibrous webs include particulates. When the gear is rotated in a first direction, the container is raised inside the cargo space of the vehicle. The logic unit then writes data stored in the buffer to the target vector register.
