Effect of stress path, size and shape on the optimum parameters of a brittle-ductile concrete model

open access: yesEngineering Structures and Technologies, 2017
The main purpose of this study is to investigate the effects of the stress path, size and shape of the specimen, on the optimum values of the plastic input parameters of Concrete Damaged Plasticity-CDP- model of the ABAQUS software.

Superb creep lives of Ni-based single crystal superalloy through size effects and strengthening heterostructure γ/γʹ interfaces

open access: yesNational Science Open, 2023
This study presents a design strategy to enhance the high-temperature creep resistance of Ni-based superalloys. This strategy focuses on two principles: (1) minimizing the dimensions of γ/γ′ interfaces and γ channels by reducing the size of the γ′ phase;

Molecular Methods for Rare Hemoglobinopathy Cases: First Brazilian Report of Pediatric Siblings with Hb O‐Arab and Alpha‐Thalassemia

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Hemoglobinopathies are prevalent globally; diagnosis is complex in high genetic admixture populations like Brazil. We report, in two pediatric siblings, the first documented cases in Brazil of heterozygosity for hemoglobin (Hb) O‐Arab with coinheritance of α‐thalassemia (αα/−α4.2; −α3.7/−α4.2), resulting in microcytic and hypochromic anemia ...

Nanoindentation Investigation on the Size-Dependent Creep Behavior in a Zr-Cu-Ag-Al Bulk Metallic Glass

open access: yesMetals, 2019
Nanoindentation technology has been widely adopted to study creep behavior in small regions. However, nanoindentation creep behavior of metallic glass is still not well understood.

Criterion‐Related Validity of the Neuropsychological Quick Assessment for Screening Cognitive, Motor, and Behavioral Impairments in Patients With Pediatric Brain Tumors: An Observational Pilot Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Neuropsychological complications may impair the qualitative prognosis of patients with pediatric brain tumors. However, multifaceted evaluations cannot be conducted in all patients because they are time consuming and burdensome for patients.

Finite-Size Effect of Hadron Masses with Kogut-Susskind Quarks [PDF]

open access: yes, 1993
We present numerical results and their analyses of finite-size effects of hadron masses for both quenched and full QCD calculations. We show that they are much larger for full QCD due to dynamical sea quarks and the associated breaking of $Z(3)$ symmetry.

Effect Size

open access: yesRevista Argentina de Cirugía, 2023
There are different measures for effect size to compare 2 means, The most common effect sizes are Cohen’s d, Hedges’ g and Glass’ delta3. I leave relative risk, odds ratios, correlation coefficients, etc., for another occasion because they are beyond the scope of this editorial and I prefer to introduce concepts slowly.

Modelling of Size Effect with Regularised Continua

open access: yesActa Polytechnica, 2004
A nonlocal damage continuum and a viscoplastic damage continuum are used to model size effects. Three-point bending specimens are analysed, whereby a distinction is made between unnotched specimens, specimens with a constant notch and specimens with a ...

Extreme scale-dependent tensile properties of epoxy fibers

open access: yeseXPRESS Polymer Letters, 2019
Epoxy fibers with different diameters were prepared by hot drawing and their mechanical properties were measured under tension. The stiffness, strength, ultimate strain, and toughness revealed substantial scale-dependent effects as they all significantly
