Nitride liner films ...

This paper focuses on an experimental study of the explosive decompression representative samples hyperbaric type IV hydrogen storage vessels. The adhesion composite to liner is achieved by different adhesives. bond behavior liner-to-composite bonded joint considerably depends properties adhesives, as well assembly process. X-ray tomography allows determining damages before and after tests. Tom...

INTRODUCTION In cementless hip arthroplasty fixation of acetabular cups is often achieved using a press-fit between the cup and the bone, where the acetabulum is typically under-reamed by 1-4mm [1-4] with respect to the size of the cup. Deformation of the cups during insertion remains a concern as it could lead to changes in the clearance and sphericity of the bearing, which can adversely affec...

landfill is the major method of solid waste disposal in developing countries. to protect soil andgroundwater from contamination, anti-seepage systems have to be installed in landfills. however, during theconstruction of anti-seepage system, many factors can result in holes in geomembrane liners. for the purpose of improving construction quality, the construction company needs to find the leaks ...

Concerning the implementation of marketing philosophies and policies in shipping companies no extensive research has been made up to now. This article presents the application of marketing philosophies and policies to the companies, which are activated in merchant (tramp and liner) and passenger shipping. The emphasis is given to the merchant shipping companies due to the fact that the passenge...

Energy savings by reducing the thermal and mechanical losses in machines is of major concern due to continuous depletion of energy resources. Frictional losses of engine components cause energy losses leading to high fuel consumption. In piston assembly, piston skirt and liner interaction contribute as much as a frictional loss as the piston rings but more studies have been focused on piston ri...

Nevertheless, in order to respond to the economic and environmental criteria, hydrogen production and storage have to be improved. This work focuses on gaseous storage under high pressure (700 bar) using a type III vessel (figure 1) that is to say composed of a metal liner – which prevents gas diffusion – and of a composite laminate wrapped by filament winding – which is used as a mechanical st...

This paper deals with the problem of delay-dependent stability criterion of arbitrary switched linear systems with time-varying delay. Based on switched quadratic Lyapunov functional approach and free-weighting matrix approach, some linear matrix inequality criterions are found to guarantee delay-dependent asymptotically stability of these systems. Simultaneously, arbitrary switched linear syst...

A direct injection gas chromatography method was developed for the determination of triethylamine and dimethyl sulfoxide (DMSO) in a drug substance (ML-189). Matrix effects were found to result in the overestimation of DMSO when methanol was used as diluent. Multiple approaches to eliminate matrix effects were unsuccessful; these included changes in sample size, split ratio, injector temperatur...
