Nomological Network of a Challenge and Hindrance Workplace Stressors Scale: A Meta-Analysis
(2018-04-13)
This research presents a meta-analysis that aims to assess the reliability and nomological network of the Cavanaugh, Boswell, Roehling, and Boudreau (2000) measure of challenge and hindrance workplace stressors, specifically, ...
Non-axisymmetric equilibrium reconstruction and suppression of density limit disruptions in a current-carrying stellarator
(2018-03-29)
Reconstruction of non-axisymmetric, three-dimensional (3D) plasma equilibria is important for understanding 3D confinement and stability in stellarators as well as in nominally axisymmetric plasmas in tokamaks and ...
Non-collocated Control of an Autonomous Robot-Trailer System Using State Estimation
(2012-04-09)
In this work, the author develops an observer and non-collocated controller for a robot-trailer system in which only the position of the trailer is measured. A linearized state-space model of the system is derived using ...
A Non-contact Method for Sensing Tire Contact Patch Deformation Using a Monocular Vision System and Speckled Image Tracking
(2011-05-16)
A full-field, non-contact deformation sensing system was developed with an application for tires. Using an image tracking algorithm, in-plane displacements and their gradients were calculated. Furthermore, the effects of ...
A Non-Cross-Coupling-Based Approach to Arene-Bridged Macrocycles and Their Use in the Development of Annulative Pi-Extension Methods
(2018-07-31)
The synthesis of strained macrocyclic benzene-containing molecules has been an area of interest for decades. However, the synthesis of macrocyclic structures that contain adjacent benzene units linked at their 1 and 4 ...
Non-Enzymatic Paper-based Urea Sensor with Hierarchical NiO Catalysts
(2022-11-29)
Urea has attracted attention because of its various potential applications, such as hydrogen production, fuel cells, fertilizers, and electrochemical sensors. Furthermore, as an end-product of human metabolism, urea is ...
Non-metric Continua that support Whitney maps
(2007-05-15)
An example of a non-metric continuum is constructed, where every non-degenerate subcontinuum is non-metric, that supports a Whitney
map. Additional non-metric examples are given and examinations of conditions under which ...
Non-perturbative calculations of atomic data for applications in laboratory fusion and astrophysical plasmas
(2012-12-13)
Results are presented for non-perturbative quantal calculations of atomic data for application in laboratory fusion and astrophysical plasmas. One of the key issues in laboratory
fusion plasmas is the accurate modeling ...
Non-platelet Purinergic Signaling and Tissue Factor Expression
(2015-12-14)
Objective—Our group found previously that human coronary artery endothelial P2Y2 receptor mediates tissue factor (TF) up-regulation at mRNA and protein levels. The exact mechanism remains unknown and can involve increased ...
Nondestructive Evaluation of Prestressed Concrete Structures by Means of Acoustic Emissions Monitoring
(2008-12-15)
The acoustic emission (AE) technique has been found to be an informative nondestructive testing (NDT) method for evaluation of structures constructed with certain materials. While AE evaluation procedures and evaluation ...
Nonequilibrium Laser-Based Synthesis of Nanoparticle Ensembles
(2020-11-17)
Two-dimensional (2D) materials have grabbed tremendous interest in the recent years because of their exotic electrical and optical properties, which make them potential candidates for next-generation electronics and ...
Nonequilibrium Thermodynamics and Fitness Costs Associated with Information Preservation May Explain Longevity Differences between Species
(2016-05-05)
The aging process in most organisms is enormously complex, involving a multitude of integrated molecular pathways that define and modulate the gradual cellular, tissue and system-level changes that evoke the aging phenotype. ...
Noninvasive hepatic lipid quantification with magnetic resonance imaging and spectroscopy
(2019-04-18)
Excessive accumulation of intra-hepatocellular lipid (IHCL) can lead to one of the most common forms of chronic liver diseases in adults, the non-alcoholic fatty liver disease (NAFLD), that comprises a range of liver ...
Nonlinear Analysis of Horses Trotting with and without Sedation
(2015-12-10)
It is common to use sedatives in equine practice for surgical procedures, standing or recumbent, and for control of unruly patients. In recent years, there have been many investigations concerning the effect sedation might ...
