Estimators of internal consistency in health research: the use of the alpha coefficient

Revista Peruana de Medicina Experimental y Salud Pública, 2015
Academic production has increased in the area of health, increasingly demanding high quality in publications of great impact. One of the ways to consider quality is through methods that increase the consistency of data analysis, such as reliability which,

Measuring subdiffusion parameters

, 2005
We propose a method to extract from experimental data the subdiffusion parameter $\alpha$ and subdiffusion coefficient $D_\alpha$ which are defined by means of the relation $ =2D_\alpha/\Gamma(1+\alpha) t^\alpha$ where $$ denotes a mean square ...

Exact solution of a one-dimensional Boltzmann equation for a granular tracer particle [PDF]

, 2006
We consider a one-dimensional system consisting of a granular tracer particle of mass $M$ in a bath of thermalized particles each of mass $m$. When the mass ratio, $M/m$, is equal to the coefficient of restitution, $\alpha$, the system maps to a a one ...

Prediction of Pressure-Viscosity Coefficient of Mixtures

Tribology Online, 2008
The pressure-viscosity coefficient α is one of the most important property for EHL condition, however its measurement has difficulty. Therefore authors attempt to predict α for blend oils by using the relationship between pressure-viscosity ...

The Logical Structure of Cronbach's Coefficient Alpha, and its Precision in Estimating Reliability under Measurement Models Assumptions. [PDF]

Journal of Islamic Studies, 2009
The study examined three main research questions: 1- What is the logical structure of Cronbach's Coefficient Alpha and its implications" 2- Under what measurement models and cicumstances the use of Coefficient Alpha produce either accurate or biased ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

FEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Validation of the Slovakian version of Boston Carpal Tunnel Syndrome Questionnaire (BCTSQ)

Acta Medica, 2019
Introduction: The most common occupational disease is carpal tunnel syndrome. The aim of this study was to translate and validate the Slovakian version of BCTSQ. Methods: The original questionnaire was translated into the Slovakian language by two expert

LDAcoop: Integrating non‐linear population dynamics into the analysis of clonogenic growth in vitro

Molecular Oncology, EarlyView.
Limiting dilution assays (LDAs) quantify clonogenic growth by seeding serial dilutions of cells and scoring wells for colony formation. The fraction of negative wells is plotted against cells seeded and analyzed using the non‐linear modeling of LDAcoop.

Friction Properties of Laminated Composite Materials of Alpha-Tricalcium Phosphate–Filled Poly (Vinyl Alcohol) Hydrogels

Tribology Online, 2015
The aim of this study was to examine the mechanical characteristics of a polyvinyl alcohol hydrogel (PVA-H) as a candidate material for artificial joint cartilage. In the study, PVA-H was filled with α-tricalcium phosphate (α-TCP) in order to

Next-to-next-to-leading order QCD corrections to the photon's parton structure

, 2001
The next-to-next-to-leading order (NNLO) corrections in massless perturbative QCD are derived for the parton distributions of the photon and the deep inelastic structure functions F_1^gamma and F_2^gamma.
