Listen to Coronavirus Patient Zero
Poetry. Dramatic and intimate, the poems in DOES SHE HAVE A NAME? trace the journeys of two women--one middle aged, the other her infant granddaughter--through near-mortal encounters with medical crises. Both survive their trials, passing from life to death and back again; both face wrenching, unpredictable challenges; both emerge from years of therapy, made whole but alone, changed by experience in apparent and invisible ways. Moving from a neonatal intensive care unit's urgent ministrations to the patient work of neurologists and speech pathologists, told from the perspectives of parent, child, husband, and witness, and exploring questions of disability, difference, and the calculated value of human life, DOES SHE HAVE A NAME? is an affecting, provocative book of poems.
Linear electric actuators (LEAs) and linear electric generators (LEGs) are widely used electromagnetic devices. This book deals with LEAs that convert electric energy into controlled mechanical motion of limited travel and LEGs that transform mechanical energy into electric energy. Examples range from loudspeakers and microphones to magnetically levitated material transfer in ultraclean rooms. Much of the literature on linear actuators and generators covers the principles of operation and performance calculations of these devices. Little has been published on their control or on detailed design methodologies. This book presents the first unified treatment of the subject, including the construction, operation, control and design of LEAs and LEGs. Chapters describe linear induction, permanent-magnet, linear reluctance, switched reluctance, and linear stepper actuators, as well as various types of linear electric generators. The text is amply illustrated with numerous design examples.
