[null,null,null,"Sommario/riassunto","This book gives an overview of modern cathodes and electron emitters for vacuum tubes and vacuum electron devices in general. It covers the latest developments in field emission theory as well as new methods towards improving thermionic and cold cathodes. It addresses thermionic cathodes, such as oxide cathodes, impregnated and scandate cathodes, as well as photocathodes and field emitters – the latter comprising carbon nanotubes, graphene and Spindt-type emitter arrays. Despite the rise and fall of the once dominant types of vacuum tubes, such as radio valves and cathode ray tubes, cathodes are continually being improved upon as new applications with increased demands arise, for example in electron beam lithography, high-power and high-frequency microwave tubes, terahertz imaging and electron sources for accelerators. Written by 17 experts in the field, the book presents the latest developments in cathodes needed for these applications, discussing the state of the art and addressing future "]

[null,null,null,"Sommario/riassunto","The Army Medical Department's Professional Filler System was developed in 1980 to support continuous overseas contingency operations while simultaneously balancing the Army's requirement to maintain a healthy force, deploy a medical force to support military operations, and manage/meet access-to-care demands for all military health system beneficiaries. PROFIS allows health care providers to practice in a military treatment facility when not deployed, which contributes to the maintenance of their medical and technical skills. The PROFIS Deployment System, developed in 2005, is an internal management system that is used to battle roster deploying units with the correct PROFIS personnel so that the U.S. Army Medical Command can plan proactively for deployments. Recently, there have been concerns over how PROFIS affects the medical readiness and availability of providers for training with the unit preparing to deploy. This report describes the functionality of the Army's PROFIS in the current operating environment and assesses potential modifications or improvements to the system. Using a literature review, interviews, a survey, and administrative data, this research sought to identify and understand the effect of PROFIS, and deployments more broadly, on providers and other military personnel. The study also assessed modifications and alternatives to the current PROFIS that might address the identified issues."]
