Advanced practice nurse-led multidisciplinary teams in healthcare settings: A scoping review
This scoping review aims to delineate the characteristics of multidisciplinary teams (MDTs) that are led by Advanced Practice Nurses (APNs) in healthcare settings, identify the roles assumed by APNs and the operational models of MDTs, and assess the impact they have on patient, caregiver, provider, and organizational outcomes
Energy consumption and mechanical proprietaries of Hybrid Deposition & Micro-Rolling
Abstract
The traditional forging process involves high energy consumption due to the giant equipment, long process, and low material utilization. Recently, metal additive manufacturing technology has developed rapidly with the advantage of high utilization. However, looseness and defects caused by the anisotropy of layer forming would result in low mechanical properties and fatigue properties. The hybrid deposition and micro rolling (HDMR) combined in-situ rolling with additive manufacturing, which applies a forging force to the built part by a micro-roller. A comparison is carried out with the conventional forging approach in terms of energy consumption and mechanical properties. It was found that components of Ti-6Al-4V made by HDMR showed a better strength performance in tensile strength and impact toughness with lower energy consumption than the traditional forging approach. Additionally, HDMR realizes integrated manufacture instead of the distributed manufacturing of large-scale equipment in a lengthy process, which is a promising substitute for conventional forging.</jats:p
