AIM To assess the diagnostic accuracy and radiation dose of split-bolus multidetector-row computed tomography (MDCT) protocol in the detection and characterization of focal liver lesions in oncologic patients. PATIENTS AND METHODS We retrospectively analyzed triphasic CT at initial diagnosis and follow-up split-bolus 64-detector row CT protocol in 48 oncologic patients with focal liver lesion...

Effect of altitude is discussed in the unsteady separation of multi stage rockets. Axisymmetric, unsteady and turbulent Navier stokes equations are solved numerically. The governing equations are split into a hyperbolic inviscid part and a parabolic diffusion part. The hyperbolic part is solved by an explicit second-order time and space of Godunov-type scheme. Moving mesh and moving boundary al...

ANALYSIS OF NON-ESTERIFIED FATTY ACIDS IN HUMAN PLASMA BY CAPILLARY GAS-CHROMATOGRAPHY WITH SPLITLESS INJECTION. The aim of the present work was to test the combination of non-esterified fatty acid (NEFA) isolation using fumed silicon dioxide with capillary gas-chromatography (C-GC) with splitless injection for the analysis of NEFAs in human plasma. Injection volume, solvent re-condensation and...

Vascular anomalies are categorized into vascular tumours or vascular malformations on the basis of clinical features and histopathology. The literature regarding high flow arteriovenous malformations of the auricle is rare. A case of a patient clinically diagnosed with an arteriovenous malformation of the external ear and was managed with preoperative embolization, surgical excision and reconst...

We consider the problems posed by routing flow in a network populated by self-interested agents. Standard node-cost and edge-cost network models are compared and a mapping between them is described. The existence of Nash equilibria when flow cannot be split is established in several cases. Braess’s paradox is shown to exist when the number of users is finite and flow is unsplittable. Finally, o...

A granular droplet that is composed of smaller and denser particles in a bed larger lighter found to sink split when subjected combination vibration fluidizing gas flow. Despite visual similarities with fluid-like instabilities, the observed phenomenon result particulate character matter. Combining experiments numerical simulations, we show high-density causes formation an immobilized zone obst...

1 This paper describes a two-stage equilibrium travel demand model. The unique feature of this model is 2 that it takes time-of-day traffic counts instead of land use and demographic data as inputs to derive spatial 3 and temporal travel demand patterns. The first stage of the model is a traffic count-based trip matrix 4 estimator; the second stage is an elastic-demand network flow estimator, w...
