Endothermic high temperature reactions are usually carried out in metal tubes heated by gas burners. Electrical heating allows substantial reduction of CO2 emissions. We propose the usage a composite tube, where thin metallic layer is embedded between an inner and outer ceramic layer. While monolithic ceramics suffer from brittleness low tolerance to thermal stress, only made ceramics, while fi...

A cylindrical elastomer tube can stay in an everted state without any external forces. If the thickness of the tube is small, the everted tube, except for the regions close to the free ends of the tube, maintains a cylindrical shape, and if the thickness is larger than a critical value, the cross-section of the everted tube becomes noncircular, which is caused by mechanical instability. Althoug...

A 64-year-old man with Parkinson’s diseasewas being treatedwith levodopa-carbidopa intestinal gel formulation through a percutaneous endoscopic gastrostomy with jejunal extension (PEG-J) tube that had been placed in 2010. In April 2014, he complained of abdominal distension, pain, bloating, food intolerance, and a pulling sensation from the PEG-J tube. At the physical examination, we observed a...

Experiments previously reported from this laboratory (1) have shown that less than 1 per cent of the “total diazo” value of the blood is actually made up of phenols, the reactive substances being almost exclusively etherinsoluble and presumably nitrogenous in nature1 (2). In the present work, an attempt was made to develop more specific methods for the determination of the various groups of uri...

Eating healthy foods supplies your body with nutrients to stay strong. But did you ever wonder how enter body? After chewing and swallowing, food is digested, enters the gut as mush. If picture intestine a tube, on inside around tube. The inner layer of tube that touches formed by special cells can transport like sugar protein. Some people cannot properly absorb nutrients. molecules also certai...

The 17th ISCHS took place in Osaka, Japan, on 23 to 25 September 2013. This symposium focuses on an exchange of views on the structure and function of hepatic sinusoidal cells in addition to their roles in clinical pathophysiology.

In this study, the deformation and energy absorption characteristics of a novel hybrid tube is investigated both experimentally numerically. The architecture proposed composed an inner conventional co-axially arranged outer auxetic tube. Quasi-static compressive tests were conducted on tubes, tubes tubes. A three-dimensional digital image correlation technique was used to monitor evolution radi...

Under torsion and beyond the buckling point, multi-walled carbon nanotubes MWCNTs develop a periodic wave-like rippling morphology. Here, we show that torsional rippling deformations can be accurately described by a simple sinusoidal shape function. Combining this observation with the geometry optimization, we develop an effective coarse-grained model that reproduces the complex nonlinear mecha...

A fluorocarbon and hydrocarbon organic solvent mixture is known as a temperature-induced phase-separation solution. When a mixed solution of tetradecafluorohexane as a fluorocarbon organic solvent and hexane as a hydrocarbon organic solvent (e.g., 71:29 volume ratio) was delivered in a capillary tube that was controlled at 10°C, the tube radial distribution phenomenon (TRDP) of the solvents was...

Capillary chromatography for the separation of optical isomers was developed using an untreated poly(tetrafluoroethylene) capillary tube and a water-hydrophilic/hydrophobic organic solvent mixture as a carrier solution. The open tubular capillary was 110 cm in length (90 cm effective length) and 100 microm in inner diameter. The carrier solution was prepared with a water-acetonitrile-ethyl acet...
