Designed for undergraduate and postgraduate students of mathematics, the book can also be used by those preparing for various competitive examinations. The text starts with a brief introduction to results from Set theory and Number theory. It then goes on to cover Groups, Rings, Fields and Linear Algebra. The topics under groups include subgroups, finitely generated abelian groups, group actions, solvable and nilpotent groups. The course in ring theory covers ideals, embedding of rings, Euclidean domains, PIDs, UFDs, polynomial rings, Noetherian (Artinian) rings. Topics of field include algebraic extensions, splitting fields, normal extensions, separable extensions, algebraically closed fiel...

"The availability of services provided by psychologists in perinatal care is a relatively recent event. It remains uncommon for a neonatal intensive care unit (NICU) to have a psychologist as a dedicated staff member, although the number of NICU psychologists is increasing. This volume is primarily concerned with perinatal services provided by psychologists. I do, however, want to make note at the beginning of the valuable role of social workers as a complement to the care offered by psychologists. Social workers have been available in NICUs since the mid-1960s. The National Association of Perinatal Social Workers (NAPSW) was founded in 1980 to help standardize training and services. The ini...
NASA's current missions to the International Space Station (ISS) and potential future exploration missions involving extended stays by astronauts on the lunar surface, as well as the possibility of near- Earth object (NEO) or Mars missions, present challenges in protecting astronauts from radiation risks. These risks arise from a number of sources, including solar particle events (SPEs), galactic cosmic rays (GCRs), secondary radiation from surface impacts, and even the nuclear isotope power sources transported with the astronauts. The serious early and late radiation health effects potentially posed by these exposures are equally varied, ranging from early signs of radiation sickness to can...
