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...

In the dairy industry world wide, several hundred types of liners are used to milk dairy cows. The enormous amount of liner types with different characteristics in size, form, consistency and other design and manufacturing characteristics indicate that no ‘best’ liner has been identified in the last 60 or so years since machine milking has become the common method for milk harvesting. Mechanica...

We reviewed the initial post-operative radiographs of the Trident acetabulum and identified a problem with seating of the metal-backed ceramic liner. We identified 117 hips in 113 patients who had undergone primary total hip replacement using the Trident shell with a metal-backed alumina liner. Of these, 19 (16.4%) were noted to have incomplete seating of the liner, as judged by plain anteropos...

This article describes a case of late locking mechanism failure and disassociation of a Pinnacle acetabular cup (DePuy, Warsaw, Indiana) and Marathon polyethylene liner (DePuy) 53 months after routine primary total hip arthroplasty in an active patient. Following an uncomplicated initial postoperative recovery, the patient felt a pop while kneeling for gardening activities. The patient had no p...

The contaminants in the landfill leachate press pose a grave threat to environment of the soil and the groundwater beneath the landfill. Despite there being strict requirements in relevant provisions of both domestic and foreign countries for the design of the bottom liner system. Pollution of the soil and the groundwater still took place in a number of landfills because of the leakage. To inve...

PURPOSE This study aimed to compare the effect of satisfaction and perceived problems between Pelite, Dermo with shuttle lock, and Seal-In X5 liners on the transtibial amputees. MATERIAL AND METHODS A total of thirty transtibial amputees (17 male, 13 female) volunteered to take part in this research. Two prostheses were fabricated for each participant. Prosthetic Evaluation Questionnaire (PEQ...
