purpose : to report a patient with retained broken probe tip in the false passage site after nasolacrimal duct (nld) probing case report : a 18-month-baby with epiphora and a nontender mass in the site of lacrimal sac was visited in clinic. she had a history of probing six months ago by another ophthalmologist. the probing was repeated successfully but the mass size didn’t change. the mass was ...
In performing vibration analysis of the car engine on the engine support, it is necessary to know the mass properties of the engine including mass, position of the center of mass and mass inertia moments. Because the car engine has a relatively complex geometric shape and is composed of different components with different densities, determining its mass properties faces many challenges. There a...
The exclusive production of charged pions, are reported in the proton-proton collisions, where the π+π- pair is emitted at the central rapidity, y, and the scattered protons stay intact (p) without detection. This measurement is performed with the CMS detector at the LHC, using a data sample corresponding to an integrated luminosity of 450 μb-1 collected at a center-of-mass energy of 7 TeV. Th...
sepahan is a new bread wheat cultivar derived from progenies of a cross made between azadi cultivar and some high yielding and resistant to rust advanced lines. all selections were made in kelardasht and iranshahr stations and early evaluations in karaj. it was also studied in regional uniform yield trials in moderate stations including kaboutar abad. results revealed that this line is more tol...
In this paper, we investigate the phonon transmission coefficient of a mass-spring in the presence of Kohn interaction by using Green’s function method within the harmonic approximation. This system is embedded between two simple phononic leads including only the nearest neighbor interactions. The results show that the presence of Kohn and the nearest neighbor interactions in the center wire m...
The Unruh effect is the prediction that particle detectors accelerated through vacuum get excited by apparent presence of radiation quanta -- a fundamental quantum phenomenon in acceleration. Prior treatments effect, presume classically prescribed trajectory, do not account for dynamics detector's center-of-mass. Here, we study more realistic whose center mass quantized degree freedom being an ...
