The Divertor Tokamak Test (DTT) is a new experimental facility whose construction starting in Frascati, Rome, Italy; its main goals are improving the understanding of plasma-wall interactions and supporting development ITER DEMO. DTT will be equipped with Neutral Beam Injector (NBI) based on negative deuterium ions, designed to inject 10 MW power tokamak. A fundamental system for good operation...

We investigate finite amplitude stability of spatially inhomogeneous steady state an incompressible viscoelastic fluid which occupies a mechanically isolated vessel with walls kept at non-uniform temperature. For wide class models including the Oldroyd-B model, Giesekus FENE-P Johnson–Segalman and Phan–Thien–Tanner model we prove that is stable subject to any perturbation.

purpose : to present the conjunctival aphthous ulceration in behçet’s disease (bd) case report : a 36-year-old woman with a known history of bd presenting an isolated, monosymptomatic conjunctival bulbar aphthosis. the eye was photophobic and painful. the lesion appeared four days prior to the consultation and measured 3.5 to 1.5 mm, which was totally excised and underwent pathological investig...

coronary heart disease has been one of the main threats of human health. coronary angiography is taken as the “gold standard” for the assessment of coronary artery disease. but sometimes, the images are difficult to interpret visually because of the crossing and overlapping of the vessels in the angiograms. vessel extraction from x-ray angiograms has been a challenging problem for several years...

Mixing of powder into liquid is very easy: You simply pour it onto the surface of the liquid and then you mix it in. It is quite clear that this creates a lot of dust – powder falls beneath the vessel but knifes and other equipment may fall into the vessel instead. It is obvious that powder sticks to the walls of the vessel and other devices inside and it is supposed to be normal, that lumps an...

A non-invasive method of imaging laser irradiated blood vessels has been achieved using Color Doppler Optical Coherence Tomography (CDOCT). This method may increase understanding of the mechanisms behind treatment of vascular disorders. The CDOCT system used a 1280 nm center wavelength superluminescent diode. A 585 nm, 360 aes pulsed dye laser was used to irradiate hamster dorsal skin flap wind...

OBJECTIVE To study the effect of Simulated Microgravity and its Associated Mechanism on Pulmonary Circulation in Rats). METHODS Rat tail-suspension model was used to simulate the physiological effects of microgravity and changes in pulmonary blood vessel morphology, pulmonary arterial and venous blood pressure, pulmonary vascular resistance, pulmonary vasomotoricity, as well as the regulation...

A two-dimensional multiscale model is introduced for studying formation of a thrombus (clot) in a blood vessel. It involves components for modelling viscous, incompressible blood plasma; non-activated and activated platelets; blood cells; activating chemicals; fibrinogen; and vessel walls and their interactions. The macroscale dynamics of the blood flow is described by the continuum Navier-Stok...

We report the fabrication of a scaffold (hereafter referred to as AngioChip) that supports the assembly of parenchymal cells on a mechanically tunable matrix surrounding a perfusable, branched, three-dimensional microchannel network coated with endothelial cells. The design of AngioChip decouples the material choices for the engineered vessel network and for cell seeding in the parenchyma, enab...
