In recent years, the dirt pick up problem and loss quality of brightness of traffic marking paints have widely attracted municipal authorities’ attention. Reflective traffic paints and road marking are some of the most technologically advanced pieces of safety and traffic signs that should be there to have safe streets [1-5]. The most important problem regarding with today’s traffic marking pai...

In a cross-sectional, population-based study in Tromsø, Norway, the authors investigated correlations between lumen diameter in the right common carotid artery (CCA) and the diameters of the femoral artery and abdominal aorta and whether CCA lumen diameter was a risk factor for abdominal aortic aneurysm (AAA). Ultrasonography was performed in 6,400 men and women aged 25–84 years during 1994–199...

an experimental study was carried out on the wake of a cylinder on the back of which a plate is installed parallel to the fluid flow, with different terminal angles, where the reynolds number is 50000. at the end of the plate, blades with the height of 0.25 equal to the cylinder diameter and with 45, 90 and 135 degrees angle from the horizon, are installed where the cylinder diameter is equal t...

Spherically symmetric direct-drive-ignition designs driven by laser beams with a focal-spot size nearly equal to the target diameter suffer from energy losses due to crossed-beam energy transfer (CBET). Significant reduction of CBET and improvements in implosion hydrodynamic efficiency can be achieved by reducing the beam diameter. Narrow beams increase low-mode perturbations of the targets bec...

The accuracy of the 0.001-ml calibrated platinum loop was tested by two methods: visible absorption spectroscopy and weight determinations. By both methods it was demonstrated that the volume of the loop delivery is related to the angle at which the loop is withdrawn from the solution being sampled and the diameter of the container, provided that the volume in the container is adequate to cover...

In this paper, triangle-free distance-regular graphs with diameter 3 and an eigenvalue θ with multiplicity equal to their valency are studied. Let Γ be such a graph. We first show that θ = −1 if and only if Γ is antipodal. Then we assume that the graph Γ is primitive. We show that it is formally self-dual (and hence Q-polynomial and 1-homogeneous), all its eigenvalues are integral, and the eige...
