Influence of the Lewis Number on Effective Strain Rates in Weakly Turbulent Premixed Combustion

open access: yes, 2018
The influence of the global Lewis number, Le, on the statistical behavior of the “effective” normal and tangential strain rates have been analyzed based on three-dimensional direct numerical simulation data of freely propagating statistically planar ...

Alcohol‐induced altered glycans in human tracheal epithelial cells promote bacterial adhesion

open access: yesFEBS Open Bio, EarlyView.
Alcohol induces altered glycans to promote bacteria adhesion. Heavy alcohol drinking is known to increase the risk of bacterial pneumonia. However, the link between alcohol levels and risk of infection remains underexplored. Recently, we found that alcohol induced α2‐6sialo mucin O‐glycans in human tracheobronchial epithelial cells, which mediated the ...

DNS analysis on the correlation between local burning velocity and flame displacement speed of turbulent premixed flames

open access: yesJournal of Thermal Science and Technology
The local burning velocity and flame displacement speed are the major properties of premixed flames. The local burning velocity, which is the instantaneous quantity based on the local consumption rate of the unburnt mixture, is considered to be the most ...

Differential Item Functioning on the Patient Health Questionnaire 8 by Disease Subtype, Language, Sex, and Age Among People With Systemic Sclerosis: A Scleroderma Patient‐Centered Intervention Network Cohort Study

open access: yesArthritis Care &Research, EarlyView.
Objective Somatic items used in depression assessments can potentially overlap with symptoms related to physical illness, including systemic sclerosis (SSc). No studies have looked at whether somatic depression items may be influenced by diffuse versus limited SSc disease subtypes, which are associated with varying degrees of symptom presentation.

Triangular Index Ratio as An Alternative Method to the Alpha Angle for Defining the Presence of Cam Morphology: A Prospective Cohort Study

open access: yesArthritis Care &Research, Accepted Article.
Objective Cam morphology, a significant risk factor for hip osteoarthritis, is commonly quantified by the alpha angle (AA). This study aims to explore the potential of the triangular index ratio (TIR) to quantify cam morphology on anteroposterior radiographs by assessing the association between TIR‐defined cam morphology and the development of ...

Catalytic Acetylation of Aromatics with Metal Chlorides and Solid Acids − a Comparative Study

open access: yesEurasian Chemico-Technological Journal, 2004
Evaluation of catalytic performances of selected metal chlorides such as AlCl3, SnCl4, ZnCl2, FeCl3, InCl3 and GaCl3 with solid acids such as sulfated zirconia, and zeolite beta was accomplished for acetylation of anisole, toluene and naphthalene ...

Arrhenius activation energy of tangent hyperbolic nanofluid over a cone with radiation absorption

open access: yesResults in Engineering, 2022
This study focuses on an incompressible non-Newtonian nanofluid in a 2-dimensional transient boundary layer through a cone. The Arrhenius activation energy and radiation absorption are both accounted for the non-Newtonian nanofluid model. The Runge-Kutta

An upper bound for the bulk burning rate for systems

open access: yes, 2000
We consider a system of reaction-diffusion equations with passive advection term and Lewis number not equal to one. Such systems are used to describe chemical reactions in a flow in a situation where temperature and material diffusivities are not equal ...

Obesity subtypes and longitudinal trajectories of function over 7‐years of follow‐up: data from the Multicenter Osteoarthritis Study

open access: yesArthritis Care &Research, Accepted Article.
Background Obesity, defined by BMI ≥30kg/m2, is a risk factor for functional limitations in people with knee osteoarthritis (OA). However, function varies among such individuals. Our objective was to evaluate the implications of obesity subtypes on longitudinal patterns of physical functioning in people with or at risk for knee OA.
