Objectives: There are some comorbidity between migraine, tension headaches, and some psychological  factors including Early Maladaptive Schemas (EMSs). This research aimed to identify the EMSs  associated with migraine and tension headaches.  Methods:  The present study was of cross sectional and correlational studies. The measures included  Headache Disability Invento...

We study droplet coalescence in a molecular system with a variable viscosity and a colloid-polymer mixture with an ultralow surface tension. When either the viscosity is large or the surface tension is small enough, we observe that the opening of the liquid bridge initially proceeds at a constant speed set by the capillary velocity. In the first system we show that inertial effects become domin...

The binding affinity of a curvature-sensing protein domain (N-BAR) is measured as a function of applied osmotic stress while the membrane curvature is nearly constant. Varying the osmotic stress allows us to control membrane tension, which provides a probe of the mechanism of binding. We study the N-BAR domain of the Drosophila amphiphysin and monitor its binding on 50 nm-radius vesicles compos...

in this paper the density and temperature dependencies of surface tension are investigated. using the lennard-jones (12,6), as an effective pair interaction potential, a linear expression is derived for isotherms of g /r2  versus r2 for some normal and chlorofluorocarbons (cfcs) fluids, where  is surface tension and r = 1/v is molar density. the linearity behavior of the derived equation is wel...

Introduction In vitro expansion and differentiation of mesenchymal stem cells (MSCs) rely on specific environmental conditions. One crucial factor is the oxygen tension. Low oxygen tension improves MSC expansion in vitro. Moreover, it accelerates the induction of a chondrogenic phenotype in subsequent 3D differentiation cultures. However, clones of MSCs from the same donor often differ in their...

The COz tension is a necessary factor in determining the acidbase equilibrium of the blood. It has been determined for blood both directly, and indirectly through CO2 of the alveolar air. The blood, because of oxidation, reduction, forced breathing, and stasis through constriction of the veins, undergoes variations in the COz tension. Does the cerebrospinal fluid which exists in a more isolated...

A new approach based on volume preserving motion by mean curvature for treating surface tension in two-phase flows is introduced. Many numerical tests and a theoretical justification are included which provide evidence regarding the efficacy of the new approach. For many flows, which exhibit stiff surface tension effects, the new approach gives a factor of at least three and sometimes five or m...

The purpose of this study is to investigate the effects hole/holes on stress concentrations in a plate using current industry standard software - Finite Element Analysis (FEA). Plate with common engineering application such as automobile, marine, aerospace and mechanical structures. Hole/Holes can be seen many thin-walled automobile structures components. For example, are found residential/comm...
