The development of new types of planetary and planetary face-gear drives is proposed. The new designs are based on regulating backlash between the gears and modifying the tooth surfaces to improve the design. The goal of this work is to obtain a nearly uniform distribution of load between the planet gears. In addition, a new type of planetary face-gear drive was developed in this project.

People all over the world are confronted daily by issues such as poverty, a lack of access to quality education, unaffordable and or inadequate housing, and a lack of needed health and mental services. These issues are dynamic and varied, and social workers need to have access to relevant and timely evidence-based materials to meet the needs of those facing them. The Social Workers' Desk Reference is a comprehensive resource for practicing social workers. This essential reference is extraordinarily comprehensive and provides updated information in 15 parts covering the profession and its overarching themes; values, ethics, licensure; theoretical constructs; assessment; treatment plans; techniques; individual, family, and group Interventions; evidence-based practice; case management; community practice; vulnerable populations; behavioral and mental health; school social work; military social work; and forensic social work. All 163 chapters, written by experts in the field, are focused, practical, and contain critical content in addition to websites and updated references. The fourth edition follows in the tradition of the first three editions and updates previous topics but fearlessly addresses current salient subjects such as white nationalism, gaming disorder, substance abuse, LGBTQ+ populations, suicide, sexual violence in the military, smart decarceration, the legacy of racism, neurobiology, technology and social work practice, Islamophobia, pseudoscientific behavioral and mental health treatments, emerging fields of practice, and more. It has greatly expanded its section on vulnerable populations to address the wide variety of diversity in the U.S.

With advances in carbon composite material, magnetic bearings, microprocessors, and high-speed power switching devices, work has begun on a space qualifiable Energy Momentum Wheel (EMW). An EMW is a device that can be used on a satellite to store energy, like a chemical battery, and manage angular momentum, like a reaction wheel. These combined functions are achieved by the simultaneous and balanced operation of two or more energy storage flywheels. An energy storage flywheel typically consists of a carbon composite rotor driven by a brushless DC motor/generator. Each rotor has a relatively large angular moment of inertia and is suspended on magnetic bearings to minimize energy loss. The use of flywheel batteries on spacecraft will increase system efficiencies (mass and power), while reducing design-production time and life-cycle cost. This paper will present a discussion of flywheel battery design considerations and a simulation of spacecraft system performance utilizing four flywheel batteries to combine energy storage and momentum management for a typical LEO satellite. A proposed set of control laws and an engineering animation will also be presented. Once flight qualified and demonstrated, space flywheel batteries may alter the architecture of most medium and high-powered spacecraft.

This book is intended to be a guide to enable protestants to discern the difference between false religion and true religion.

In his most celebrated work, Mexican writer Francisco Rojas Gonzalez offers a rare blend of literature and indigenous anthropology. Inspired by his fieldwork in Chiapas, Mexico, these 13 stories reflect the author's preoccupation with the totality of Mexican life and capture his heralded ability to penetrate the contradictions of human nature. The book is a dramatic presentation of myths, religious beliefs, and customs of Mexican Indians framed in their rigid, overpowering code of ethics. It served as the basis for the 1954 film "Roots," which won the FIPRESCI Prize at the Cannes Film Festival of 1955.
