background: common carotid arterial stiffness can be assessed during carotid arterial ultrasonography, but its association with brachial stiffness, a well-defined cardiovascular risk factor, has not been clarified. the aim of this study was to examine the relationship between common carotid artery and brachial artery stiffness. methods: the static pressure-strain elastic modulus of the common c...

background substrates in medical science are hydrophilic polymers undergoing volume expansion when exposed to culture medium that influenced on cell attachment. although crosslinking by chemical agents could reduce water uptake and promote mechanical properties, these networks would release crosslinking agents. in order to overcome this weakness, silicone rubber is used and reinforced by nanocl...

objective: to evaluate the current scientific evidence for the applicability, safety and effectiveness of pathways of enhanced recovery after emergency surgery (eras). methods: we undertook a search using pubmed and cochrane databases for eras protocols in emergency cases. the search generated 65 titles; after eliminating the papers not meeting search criteria, we selected 4 cohort studies and ...

In the current study we briefly review advantages of utilising elastic neutron scattering techniques to reveal structure porous materials and pore-confined fluids. Furthermore, highlight benefits in situ CO2 injection model systems as well sedimentary rocks explore pore morphology, accessibility structural properties CO2. This information is important for design optimal sequestration gas oil re...

Compressive mechanical stimuli are crucial in regenerating cartilage with tissue engineering, which creates a need for scaffolds that can maintain their mechanical integrity while delivering mechanical signals to adherent cells during strain applications. With these goals in mind, the aim of this study was to develop a mechano-active scaffold that facilitated effective cartilaginous tissue form...

In the current paper, finite element method is employed for numerical simulations and the study of influential parameters on elastic modulus of polymer-matrix nano-composites. Effects of different key parameters including particle elastic modulus, interphase elastic modulus, matrix elastic modulus, interphase thickness and particle volume fraction on total elastic modulus of nano-composite mate...

A technique has been developed for the recognition of unconstrained handwritten discrete symbols based on elastic matching against a set of prototypes generated by individual writers. The incorporation of feature analysis with elastic matching to eliminate unlikely prototypes is presented in this paper and is shown to greatly reduce the required processing time without any deterioration in reco...

Error estimation and adaptive applications help to control the discretization errors in finite element analysis. The study implements radial point interpolation (RPI)-based error-recovery approaches displacement/pressure-based mixed approach is used formulation. RPI considers basis functions (RBF) polynomials together interpolate solutions, i.e., displacement over influence zones recover soluti...
