OBJECTIVE To analyze the results of flexible ureterorenoscopy (F-URS) with holmium laser in the treatment of kidney stones with ectopic and fusion anomalies (horseshoe kidney and rotation anomalies). METHOD We reviewed data from 13 patients with fusion and ectopic renal anomalies that underwent F-URS from April 2011 to April 2017. We analyzed demographic and clinical data (age, gender, BMI, a...

objectives: this study aimed to evaluate the effect of storage period on dimensional stability of alginplus and hydrogum 5. materials and methods: in this in vitro experimental study, 60 impressions were taken of an upper jaw typodont, including 10 impressions for each storage period to be tested (12 minutes, 24 and 120 hours) for each type of alginate. then, the impressions were stored in an i...

Frame saw machine is one of tools that used to process dimension stone. The velocity fluctuation traditional feed drive system (FDS) lead excessive wear diamond particles. dynamic performance the FDS has time-varying characteristics during processing stone with a large material removal rate. In this paper, novel was proposed. Firstly, modeling set up on account lumped parameter method (LPM). Th...

The Mawat ophiolite complex (MOC) is a part of the Zagros Suture Zone, which extends about 2000 km from southeastern Turkey through northern Syria and Iraq to western southern Iran. serpentinite rocks are exposed at Waras area near Betwat village. Serpentinite this have been studied assess their suitability for use as dimension stone. Ten samples were collected in establish physical mechanical ...

Local Lorentz invariance is an important component of General Relativity. Testing for Local Lorentz invariance can not only probe the foundation stone of General Relativity but also help to explore the unified theory for General Relativity and quantum mechanics. In this paper, we search the Local Lorentz invariance violation associated with operators of mass dimension d = 6 in the pure-gravity ...

To lower bound the effective dimension for local Hamiltonian models, we will use a theorem from [1, 2] as a stepping stone. This is a quantum version of the BerryEsseen theorem. The Berry-Esseen theorem is a more powerful statement than the central limit theorem, as it gives the rate of convergence of a distribution to a Gaussian. Let H = ∑ ν Eν |ν〉〈ν| be k-local, i.e., let H be of the form H =...
