Surface-micromachined Ta–Si–N beams for use in micromechanics

Realization and characterization of free-standing surface-microstructures based on Ta-Si-N films are presented. Due to their significant physical and chemical properties, such ternary films are promising candidates for application in microelectromechanical devices

A look into the challenges and complexities of managing low back pain in Mexico

Low back pain is a global health problem. In Mexico it is one of the most common musculoskeletal conditions as well as the leading cause of disability. This review provides an overview of the challenges and complexities of managing low back pain in Mexico.
