Aim: Gingival margins of posterior composite restorations is usually more apical compared to CEJ. The present study was aimed to determine the microleakage in gingival margins of Class II composite restorations through using three different types of resin cements as liners. Materials and Methods: In this in-vitro study, two mesial and distal Class II cavities with 1mm gingival margins were crea...

The interface between stump and liner (socket) is subject of high pressure in different moments of gait cycle due to loading variation in body movement. The liner is the interface between socket and skin along with soft tissue and bones in a cycling loading. The result is a friction effect combined with pressure that conduct to the heating of skin and liner. The effect is and increasing of pres...

OBJECTIVE To investigate the effect of a standardized silicone liner programme on the duration of prosthetic rehabilitation in patients who underwent transtibial amputation as a result of peripheral arterial disease. METHODS This retrospective study enrolled patients who underwent transtibial amputation followed by one of two stump management programmes at the same rehabilitation centre over ...

Prevention of damage to the teat and mastitis requires determination of the teat load caused by a collapsing liner. The aim of this study was to test a pressure-indicating film designed to measure the pressure between a collapsing liner and artificial teats. The Ultra Super Low and the Extreme Low pressure-indicating films were tested on two types of artificial teat. The experiments were perfor...

The significant costs insert on mineral processes due to mill liner wear including the labor costs, price of material and shut down periods. Therefore, the study of this phenomenon is economically important to optimize the mill operating conditions and liner profile design to decrease the wear rate. There is no appropriate and applicable research on impact wear evaluation of mill liners. In the...

Fragile histidine triad (FHIT) serves a critical function as a tumor suppressor that inhibits p53 degradation by mouse double minute 2 (MDM2). The functional domains of FHIT involved in tumor inhibition was interpreted. In-silico screening data were employed to construct truncated forms of FHIT to assess their cytotoxic effects on the HT1080 cell line. Full FHIT expression was confirmed by west...

A patient suffering from diabetes and a trans-tibial amputation presented with stump wounds caused by improper donning of the liner. His diminished hand function resulted in improper donning, with air being trapped between the liner and stump. This caused blisters on the skin after loading the prosthesis.

Much recent progress has been made theoretically and computationally towards understanding the importance of conical intersections for chemical reactions. Nonetheless, experimental characterization of conical intersections has proven extremely difficult with one striking exception: the Jahn-Teller conical intersection. This article overviews the fundamental similarity of a variety of conical in...

Cardboard liners are often installed within automotive drive shafts to reduce radiated noise over a certain frequency range. However, the precise mechanisms that yield noise attenuation are not well understood. To overcome this void, a thin shell (under free boundaries) with different cardboard liner thicknesses is examined using analytical, computational and experimental methods. First, an exp...
