The new resilient denture liner "M" was evaluated for adhesion, color stability, surface texture, tissue response, deterioration and denture base stability, at periods of 1 month, 3 months and about 30 months after denture liner application. At the observation of approximately 30 months, the usage of 17 dentures had been discontinued within 2 years, and 6 dentures continued to be used. It could...

Abstract In order to study the formation and penetration performance of reactive liner, in this paper, a Ta-Zr alloy is used as liner material, large cone angle spherical arc-cone are simulated analyzed by using AUTODYN software. The following conclusions obtained: (1) EFP formed has good flight stability, followed arc liner; (2) length diameter ratio shaped charge larger than that (3) depth la...

The first controlled experiments measuring the growth of the magneto-Rayleigh-Taylor instability in fast (∼100  ns) Z-pinch plasmas are reported. Sinusoidal perturbations on the surface of an initially solid Al tube (liner) with wavelengths of 25-400  μm were used to seed the instability. Radiographs with 15  μm resolution captured the evolution of the outer liner surface. Comparisons with nume...

Over the last twenty years a wave of consolidation has swept through the oceanic liner shipping industry, leaving the industry dominated by a small number of large firms organized into a handful of strategic alliances. As liner shipping is the dominant form of international transportation these changes have likely had a substantial impact of the global trading system. This paper empirically exa...

PURPOSE To determine the survival rate of the Harris-Galante (HG) II cup and identify factors contributing to failure. METHODS 271 primary total hip arthroplasties (THAs) performed between 1992 and 1999 in our hospitals using the HG II acetabular cup were retrospectively reviewed due to a high incidence of liner dissociation. RESULTS 48 THAs were revised, 32 (67%) of which were due to liner...

The Liner Shipping Fleet Repositioning Problem (LSFRP) poses a large financial burden on liner shipping firms. During repositioning, vessels are moved between services in a liner shipping network. The LSFRP is characterized by chains of interacting activities, many of which have costs that are a function of their duration; for example, sailing slowly between two ports is cheaper than sailing qu...

We describe an experiment to form and characterize a section of a spherically imploding plasma liner by merging six supersonic plasma jets launched by newly designed contouredgap coaxial plasma guns. This experiment is a prelude to forming a fully spherical imploding plasma liner using many dozens of plasma guns, as a standoff driver for plasma-jet-driven magnetoinertial fusion. The objectives ...

Soft liner materials in oral cavity environments are easily colonized both by fungi and dental plaque. These factors are the cause of mucosal infections. The microorganism that most frequently colonizes soft liner materials is Candida albicans. Colonization occurs on the surface of materials and within materials. A solution to this problem might involve modification of soft liner materials with...

A resilient soft liner (RSL) has been used in processed complete dentures but controlling its thickness has always been a challenge because of uneven reduction of the denture’s intaglio surface. Use of a thermoplastic vacuum-formed template and an endodontic K-file, as guides, for the reduction of a processed mandibular complete denture to receive RSL is described in the present report. A proce...

The aim of this study was to investigate the efficiency of four different mineral liners (clay, bentonite, kaoline, and zeolite) which could be utilized to prevent the transport of phenolic compounds to groundwater through alternative liner systems. Four laboratory-scale HDPE reactors with 80 cm height and 40 cm inner diameter were operated for a period of 180 days. Results indicated that the t...
