PRINCIPLES The nine equivalents of nursing manpower use score (NEMS) is frequently used to quantify, evaluate and allocate nursing workload at intensive care unit level. In Switzerland it has also become a key component in defining the degree of ICU hospital reimbursement. The accuracy of nurse registered NEMS scores in real life was assessed and error-prone variables were identified. METHODS...

INTRODUCTION Researchers believe that nutrition environments contribute to obesity and may explain some health disparities. The Nutrition Environment Measures Surveys (NEMS) are valid and reliable observational measures of the nutrition environment. This article describes the dissemination of the measures, including the development, implementation, and evaluation of training workshops, and a fo...

Robotic manipulation at the nanometer scale is a promising technology for structuring, characterizing and assembling nano building blocks into nanoelectromechanical systems (NEMS). Combined with recently developed nanofabrication processes, a hybrid approach to building NEMS from individual carbon nanotubes (CNTs) and SiGe/Si nanocoils is described. Nanosensors and nanoactuators are investigate...

INTRODUCTION University campuses offer an opportunity to study the extent to which modifying the food environment influences eating, but in-depth characterizations of campus food environments are needed to identify potential targets for intervention. The objective of this project was to describe the availability, accessibility, and quality of healthful food choices in dining venues and food sto...

INTRODUCTION The community food environment may contribute to obesity by influencing food choice. Store and restaurant audits are increasingly common methods for assessing food environments, but are time consuming and costly. A valid, reliable brief measurement tool is needed. The purpose of this study was to develop and validate reduced-item food environment audit tools for stores and restaura...

The oscillatory dynamics of nanoelectromechanical systems (NEMS) is at the heart many emerging applications in nanotechnology. For common NEMS, such as beams and strings, formulated using a dissipationless wave equation derived from elasticity. Under harmonic ansatz, gives an undamped free vibration equation; solving this with proper boundary conditions provides eigenfunctions familiar standing...

Abstract Ultraviolet (UV) electro-optic modulation system based on graphene-plasmonic metamaterials nanomechanical (NEMS) with superlubricity is investigated. Due to the strong optical absorption intensity of graphene in UV region and combination metamaterial structure surface plasmons, depth NEMS modulator approaches as high 8.5 times compared counterpart visible light region. Meanwhile, signi...

OBJECTIVE To test the use of a human resources-based classification of levels of care of ICUs; to evaluate the match between planned vs operative levels of care on a large sample of European ICUs. DESIGN Analysis of the database of a multicentric, multinational, prospective cohort study, involving 89 ICUs from 13 European areas. SETTING Database of EURICUS-I. METHODS Provision of resource...

The physics of operation of nanotube NEMS devices is reviewed. Special attention is paid to non-classical effects, rarely described in MEMS analysis, such as van der Waals/Casimir interactions, quantum effects in electrostatics, atomistic parameterization of elasticity. As an example of a breakdown of a classical MEMS theory, the NEMS scaling limitation is derived in a lump model taking into ac...

Quantum squeezing can improve the ultimate measurement precision by squeezing one desired fluctuation of the two physical quantities in Heisenberg relation. We propose a scheme to obtain squeezed states through graphene nanoelectromechanical system (NEMS) taking advantage of their thin thickness in principle. Two key criteria of achieving squeezing states, zero-point displacement uncertainty an...
