instrument breakage during treatment can lead to serious complications and carries the risk of treatment failure. when a file breaks in the canal, bypassing or removal can be difficult and the long-term prognosis of the tooth may be compromised. sometimes surgery may be indicated for removal of the broken segment. often some part of the root cannot be cleaned because of blockage by the broken f...

The hair was immediately removed from the neighbourhood of the wound, and as it was matted with blood the whole scalp was subsequently shaved, when also a contused wound was found to exist over the parietal bone of the same side'. A bluut probe was carefully introduced and gently pressed against the cut edges of the bone, but no broken portions were felt, so I did not consider it justifiable to...

If supersymmetry is spontaneously broken at a low energy scale then the resulting gravitino will be very light. The interaction strength of the longitudinal components of such a light gravitino to e − ẽ pair then becomes comparable to that of electroweak interactions. If such a light gravitino is present it would significantly modify the crosssection for eLe − R → ẽLẽR from its MSSM value. Prec...

Objective(s): Severe injuries are often associated with tissue hypothyroidism, elevated damaging mediators in circulation, and broken gut epithelial barrier.  However, the relationships between the hypothyroid state and gut epithelial damage are largely unknown.  Therefore, in this study, we investigated the effects of L-thyroxine (T4) on in vitro models of intact and ...

magnetic force microscope ( mfm ) is a powerful technique for mapping the magnetic force gradient above the sample surface. herein, single-wall carbon nanotubes (swcnt) were used to fabricate mfm probe by dielectrophoresis method which is a reproducible and cost-effective technique. the effect of induced voltage on the deposition manner of carbon nanotubes (cnt) on the atomic force microscope (...

During cataract surgery the clouded lens is broken up by phacoemulsification. The iris can become highly mobile and could be entrained phacoemulsification probe, under a condition known as intraoperative floppy syndrome (IFIS). In this study we explore mechanism of IFIS during phacoemulsification-based using fluid-structure interaction (FSI) simulations. As first its kind, developed simplified ...

We perform the potential analysis for holographic Schwinger effect in a deformed $AdS_5$ model with conformal invariance broken by background dilaton. evaluate static analyzing classical action of string attaching rectangular Wilson loop on probe D3 brane sitting at an intermediate position bulk AdS space. observe that inclusion chemical tends to enhance production rate, reverse confining scale...

The roughly linear rise of the potential found between adjoint sources in SU(N) in lattice simulations is expected to saturate into a state of two ‘gluelumps’ due to gluonic screening. We examine this in SU(2) in 2+1 dimensions. Crossover between string-like and broken states is clearly seen by the mixing-matrix technique, using different operators to probe the two states; the breaking behaviou...

A lesion in a 73-year-old woman that was suspected to be right lung cancer was biopsied under ultrasound-guided bronchoscopy with a guide sheath. The procedure was completed without a noticeable problem, but after 3 days, it was found that the tip of the ultrasonic probe sheath was broken and that the broken fragment was missing. Based on the concern that the fragment had been left in the lung,...
