We studied the evolution of elliptic heavy SF6 gas cylinder surrounded by air when accelerated by a planar Mach 1.25 shock. A multiple dynamics imaging technology has been used to obtain one image of the experimental initial conditions and five images of the time evolution of elliptic cylinder. We compared the width and height of the circular and two kinds of elliptic gas cylinders and analyzed...

In this work, an original way of shaping chalcogenide optical components has been investigated. Thorough evaluation the properties glasses before and after 3D printing carried out in order to determine impact additive manufacturing process on material. evaluate potential such glass manufacturing, several preliminary results obtained with various objects components, as cylinders, beads, drawing ...

AIMS To quantify occupational ill health resulting from dermatitis in the UK printing industry and to explore links with particular processes and activities. METHODS Approximately 2600 members of the Graphical, Paper and Media Union living in Nottinghamshire were sent a self completion questionnaire. A sample of respondents, both those who reported current skin problems and those who did not,...

in this paper, a thermoelasticity solution for steady state response of thick cylinders which are subjected to pressure and external heat flux in inner surface is presented. displacement field obeys the kinematics of the first order shear deformation theory (fsdt). it is assumed that the temperature varies both along the length and the thickness. the variation of the temperature occurs linearly...

PURPOSE Three-dimensional (3D) printing technology allows physicians to rapidly create customized devices for patients. We report our initial clinical experience using this technology to create custom applicators for vaginal brachytherapy. MATERIAL AND METHODS Three brachytherapy patients with unique clinical needs were identified as likely to benefit from a customized vaginal applicator. Pat...

This paper studies hydrogels created by photopolymerization with a uniform beam of light. Under some conditions the density profiles of the resulting hydrogels were uniform cylinders, mirroring the illumination profiles. However, under other conditions, gels with hollow cylindrical shapes were formed. We studied the photopolymerization of poly-N-isopropylacrylamide (pNIPAAM), a hydrogel that ha...

We describe the process of designing and building a 20 degrees-of-freedom tendon-driven anthropomorphic robotic hand. We use 3D printing technology to reduce cost and save time. The entire mechanism is easily assembled thanks to our Snap-On joint design. The fingers are modular and can be individually modified with little effort. The hand is actuated by new pneumatic system consisting of an ass...

Thermoreversible hydrogels are widely used in foods, drug delivery and tissue engineering. Novel shapes/textures out of them being increasingly fabricated using Fused Deposition Modelling (FDM) type 3D printing, where gels extruded layer-by-layer above their gelling temperature followed by cooling. It is crucial to develop a library suitable materials optimise printing conditions ensure good pr...

Magnesium oxide (MgO), which develops physical strength through carbonation, is a potential alternative to carbon intensive Portland cement. In this paper, we examined whether 3D printing could improve carbonation and compressive strength. The rheology of MgO paste was modified using mixtures nanoclays methylcellulose produce cylinders with exposed open-to-air closed (solid) infills. results sh...
