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...

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 ...

The effects of surface texture on the lubrication performance of a compression ring-cylinder liner system are studied in this paper. By considering the surface roughness of the compression ring and cylinder liner, a mixed lubrication model is presented to investigate the tribological behaviors of a barrel-shaped compression ring-cylinder liner system with spherical dimples on the liner. In orde...

In this work, a decision tool is developed for a liner shipping company to deploy its fleet considering vessel speeds and to find routes for cargos with transit time constraints simultaneously. This problem is referred as Service level Assignment and Container Routing Problem (SACRP) in the sequel. A Column Generation (CG) algorithm is implemented for the SACRP. Computational experiments are pe...

Oxidised zirconium (OxZi) has been developed as an alternative bearing surface for femoral heads in total hip arthroplasty (THA). This study has investigated polyethylene wear, functional outcomes and complications, comparing OxZi and cobalt-chrome (CoCr) as part of a three-arm, multicentre randomised controlled trial. Patients undergoing THA from four institutions were prospectively randomised...

The purpose of this study was to evaluate the regional bond strength of a dual-cure resin core material to root canal dentin using four self-etching primer/adhesive systems. Post spaces were prepared in extracted premolars, and their root canal dentin was treated with one of the following self-etching primer/adhesive systems: ED Primer II and Clearfil Photobond, photo-cure/dual-cure systems of ...

Power quality (PQ) problems for renewable energy system (RES) is major challenge using these systems. Amplitude, frequency, and waveform important PQ parameters especially standalone or isolated In this paper we propose RES with wind turbine (WT) permanent magnet synchronous generator (PMSG) to feed different loads (liner, non-liner) through AC-DC-AC converter. The PMSG operate fuzzy logic iner...

Many women use panty liners between menstrual periods. The aim of this study was to investigate whether the use of such products might influence the vulva skin. Twelve healthy women were studied on four occasions with three different product constructions and on one occasion without products. Temperature, surface wetness and surface pH were measured on vulva skin. Mean skin temperature when the...

BACKGROUND AND OBJECTIVE Chemical cleansing by denture cleansers is first choice for denture plaque control. The most common problems while using denture cleansers are hardening, porosity, odor sorption, water sorption, solubility, and colour change, bacterial and fungal growth. Chemical cleansing procedures have been found to have an effect on the physical and mechanical properties of denture ...

BACKGROUND AND AIM Thermal discomfort often affects prosthesis wearers and could be addressed by increasing liner thermal conductivity. This note explores a liner made from thermally conductive silicone and two additional alternative liner designs. TECHNIQUE Thermally conductive silicone was used to create a conductive liner and a hybrid liner. Additionally, one with open elements was made. T...
