BACKGROUND AND PURPOSE In traditional radiostereometric analysis (RSA), 1 segment defines both the acetabular shell and the polyethylene liner. However, inserting beads into the polyethylene liner permits employment of the shell and liner as 2 separate segments, enabling distinct analysis of the precision of 3 measurement methods in determining femoral head penetration and shell migration. PA...

Transshipment hubs are important components of the global container shipping network. Nowadays, hybrid ports emerging, handling both gateway and transshipment traffic depending on their significant maritime connectivity. Effectively identifying hubs, including traditional with high incidences sufficient capabilities, is crucial to gain a good understanding networks. The method reinforced struct...

On the African continent, Morocco is considered among most connected countries, according to liner shipping connectivity index. Since optimal can reduce CO2 emissions and trade costs, through this paper we aimed deepen understanding of maritime based on bilateral index 138 its economic partners. We first established an overview evolution in highlighted main regional partners, then defined a sta...

Abstract To raise the income of container liner company and improve shipping space utilization rate, an integer programming model is constructed in view seaworthiness characteristics each ship route along Hanshen line Yangtze river, OD transport demand, rental business under alliance. Aiming to maximize gross profit Hanhai fleet series, was optimized network river waterway determined how choose...

This study considers the empty container repositioning problem of shipping companies that use standard and 3-in-1 foldable containers with more advanced designs. A mathematical model is developed to compare total management costs various patterns in different cargo demand scenarios. Numerous scenario analyses simulations were conducted, focusing on a liner service Pacific Islands where are like...

During milking the teat cup liner is the interface between the teat of a dairy cow and the milking system, so it should be very well adapted to the teat. Therefore, the aim of the present study was to determine the effect of liner type on the directly measuring teat load caused by a collapsing liner with a pressure-indicating film. The Extreme Low pressure-indicating film was used to detect the...

The aim of this study was to compare the 10-year survival rate, pelvic osteolysis frequency and linear head penetration rate of the Hexloc and Ringloc liners used together with a partially threaded porous and hydroxyapatite coated cup and the Bi-Metric uncemented femoral stem. The 15-year results for the cup with the Hexloc liner are also reported. We included 332 consecutive hips (166 Hexloc a...

We report a complication during total hip arthroplasty using an uncemented press-fit acetabular shell and ceramic liner for a woman with osteoarthritis. Fracture of the ceramic liner occurred during its insertion owing to non-concentric reduction. The main body of the ceramic liner became wedged in the acetabular shell and was resistant to removal. The shell itself was immovable owing to the pr...

due to availability of proper materials in landfills (at most parts of iran especially in kahrizak) and also less expenditure of this liner in comparison with other liners it can be count as an acceptable choice. different studies imply that one of the most important factors for soil liner selection is local conditions and also liner compatibility with generated leachate in studied site. hydrau...
