A double curved nasal endotracheal tube has been incorporated into a standard head drape [or improved access and visibility when providing dental treatment [or the young patient under general anesthesia. The technique [or stabilization o[ the airway to provide sa[ety and protection o[ the patient is described in detail. This method has been used successfully [or over 100 dental patients. All pa...

Because of their compact structure, ease processing and higher heat transfer coefficient, curved-tube exchangers are widely applied in various industry applications, such as nuclear power systems, solar-powered engineering, aircraft engine cooling systems refrigeration cryogenic systems. Accurate knowledge about the characteristics supercritical fluids tube is critical to design optimization a ...

Accessing a specific, predefined location identified in medical images is a common interventional task for biopsies and drug or therapy delivery. While conventional surgical needles provide little steerability, concentric tube continuum devices enable steering through curved trajectories. These devices are usually developed as robotic systems. However, manual actuation of concentric tube device...

The Moving Pictures Show is a contemporary Australian ‘silent’ film company that screens films produced in the period from 1912 to 1929, with a 9-piece orchestral accompaniment. This article explores the ways in which music is chosen for the show both to heighten the audience’s aesthetic experience of the film and to abide by historical practice. It also describes the ways in which improvisatio...

In this paper, we propose a wide-viewing-angle three-dimensional integral imaging using a curved screen and a curved lens array. Elemental images are projected to the curved screen. Incorporation of the curved screen and the curved lens array instead of a conventional flat display panel and a flat lens array expands the viewing angle remarkably. In addition adopting barriers between a curved le...

Kink oscillations of curved coronal loops with the density varying along the loop are studied in the thin tube approximation. The equilibrium magnetic field is assumed to be potential, and the field potential and flux function are used as curvilinear coordinates. It is also assumed that the loop expansion is weak, and the solution to the problem is looked for in the form of power series with re...

Tube systems are widely used in heat transfer and intensive research is being done on positioning tubes a platform. The platform structure constantly exposed to thermal changes under operating conditions the resulting stresses cause damage existing systems. In this study, 8 thin-walled were positioned flat curved platforms that stress behavior effects was investigated. Finite element analysis u...

We start from a given Lorentz metric and a vector field of world lines along which observers and measure devices may move. We describe a procedure to associate one-particle Hilbert spaces and one-particle Hamiltonians to space-like hypersurfaces using a transi, tion to a Riemannian metric. With the aid of suitable boundary conditions one can confine the particle within a world tube ("box quanti...

Two new species of Tetralidia Marques-Costa & Cavichioli, 2008: Tetralidia pachamama sp. nov. and Tetralidia viracocha sp. nov. are described and illustrated. T. pachamama sp. nov. can be distinguished from the other species of the genus by the simple aedeagus, without processes, spines or lamellae, while T. viracocha sp. nov. can be distinguished by the aedeagus with two pairs of lamellae at s...
