It is the tradition of this series of workshops that theorists and experimentalists sharing common interests discuss a variety of issues relevant to promoting the quest to unify microscopic physics and gravitation. This proceedings volume embodies that tradition. The papers are taken from the Fourth International Workshop on Gravitation and Astrophysics. They cover topics such as superconducting accelerometers, low-temperature-long-distance telescopes for gravitational waves, gravitational experiment with high-precision torsion pendulums and modern high-technology, physics of neutron stars,...

The International Conference on Gravitation and Astrophysics(ICGA) is to serve the needs of research workers in gravitation and astrophysics in the Asia-Pacific region. This proceedings covers a wide and hot area of research, including cosmological model, gravitational lensing, precision measurement of G, CMB, Kerr space-time, gravitational wave, the LISA, LIGO, LCGT projects in Japan, black hole, dark matter, Yang-Mills gravity, neutron star, type la supernovae, quasi-local energy, anti-de Sitter space-time.

This book introduces the most inspiring progress in the production of ferronickel from laterite ores, from both theoretical and technological perspectives. Based on a detailed overview of nickel utilization from laterite ores, it provides the advances of four main methods for laterite ore processing, including the solid-sate reduction-magnetic separation process, the rotary kiln reduction-electric arc furnace smelting process, the Krupp-Renn process, and the sintering-blast furnace smelting process. Moreover, for mediating the adverse impacts of the byproducts in ferronickel and subsequent...

This book introduces a unique 3D printing method that prints metal parts by ejecting metal micro-droplets: a low-cost, contactless, and environmentally friendly 3D printing technology. This book follows a deductive approach to describe the fundamentals of metal droplet-based 3D printing and reveal the relationships and unique features among multiple specific techniques used in droplet-based 3D printing. It starts with a general description of the principles and techniques involved in this technology and then focuses on the details of several specific metal droplet-ejection methods. Next, it...
