It is now known that the equations of motion for the contact point during peeling of an adhesive tape mounted on a roll introduced earlier are singular and do not support dynamical jumps across the two stable branches of the peel force function. By including the kinetic energy of the tape in the Lagrangian, we derive equations of motion that support stick-slip jumps as a natural consequence of ...

Channel flow of an incompressible fluid at Reynolds numbers above 2400 possesses a number of different spatially localized solutions that approach laminar flow far upstream and downstream. We use one such relative time-periodic solution, which corresponds to a spatially localized version of a Tollmien-Schlichting wave, to illustrate how the upstream and downstream asymptotics can be computed an...

Nowadays, the subject of vision metrology network design is local enhancement of the existing network. In the other words, it has changed from first to third order design concept. To improve the network, locally, some new camera stations should be added to the network in drawback areas. The accuracy of weak points is enhanced by the new images, if the related vision constraints are satisfied si...

The drive of this investigation is to diagnose the mediation effect of placement between program quality, industrial link, student satisfaction, and service quality in the circumstance of tertiary education in Malaysia. Using the Cue Utilization theory, the proposed model is tested employing data collected from 173 international students who are pursuing study at University Utara Malaysia throu...

Background & Aim: Saffron (Crocus sativus L.) formerly was important in Turkey. Saffron cultivation has been decreased and it is now only cultivated in three villages in this country. It is triploid and exclusively propagated in a vegetative way by corms. In Turkey, saffron is traditionally planted by placing corms in rows randomly without grading or sorting; which results in placement...

bowel stent insertion has a variety of complications one major of which is colonic perforation. the purpose of this article is to reveal two cases with delayed colonic perforation after stent placement to relieve bowel obstruction caused by rectal cancer. the first patient was a 55 year-old man who was a candidate for stent placement to avoid palliative surgery and relieve his bowel obstruction...

Localized scalp hair loss has different causes which alopecia areata, trichotillomania, tinea capitis and early lupus erythematosus are the most important ones. There are several reports of localized alopecia after tick and flea bites and bee stings, but there is only one report of ant-induced alopecia in the literature. We report herein two cases of alopecia induced by ants of genus Phei...

introduction : confirmation of proper endotracheal tube placement is one of the most important and lifesaving issues of tracheal intubation. the present study was aimed to evaluate the accuracy of tracheal ultrasonography by emergency residents in this regard.   method : this was a prospective, cross sectional study for evaluating the diagnostic accuracy of ultrasonography in endotracheal tube ...

In this paper, we present soliton-like solutions of the non-linear complex Klein-Gordon systems in 1+1 dimensions. We will use polar representation to introduce three different soliton-like solutions including, complex kinks (anti-kinks), radiative profiles, and localized wave-packets. Complex kinks (anti-kinks) are topological objects with zero electrical charges. Radiative profiles are object...
