AIMS AND OBJECTIVES Soft liners are mainly used with complete dentures in case of poor mucosal conditions and for the even distribution of masticatory forces. However, there is some doubt as to whether the elasticity of the soft liner disturbs masticatory function because denture wearers may need extra force to compress the soft liners, leading to muscle fatigue. So, this clinical study was don...

A 39-year-old woman underwent bilateral total hip arthroplasty with conventional, ethylene oxide-sterilised liners when she was a subject in a radiostereometric analysis study. Within 2 years she had rapid polyethylene wear with aggressive, asymptomatic, and periprosthetic osteolysis on both sides. Oral alendronate therapy halted the progression of osteolysis over a year and revision to cross-l...

BACKGROUND Radiostereometric analysis provides highly precise measurements of component micromotion relative to the bone that is otherwise undetectable by routine radiographs. This study compared, at a minimum of five years following surgery, the micromotion of tantalum and titanium acetabular cups and femoral head penetration in highly cross-linked polyethylene liners and conventional (ultra-h...

The number of lifters of mill shell liners, mill rotation speed, and filling percentage of grinding media are three of the most important parameters influencing the charge behavior and the trajectory of ball motion inside the SAG mills, and consequently, their performance. In this paper, the milling operation of pilot-scale SAG mills using the discrete element method (DEM) is investigated. Firs...

Conceptual design and optimization methods are proposed tuned structure. Reinforced concrete steel widely used in waste gas discharge industrial facilities, guaranteeing their safety performance harsh environments important industries society. T...

Geosynthetic reinforced soil (GRS) walls and abutments are increasingly used to support transportation infrastructure. A pressing question in their response is the amount of horizontal deflection expected under service loads. This paper presents an evaluation of six methods for predicting the lateral deformation of GRS walls and abutments, namely the FHWA, Geoservice, CTI, Jewell-Milligan, Wu, ...

We find that a preliminary classification of LINERs’ energetics may be made in terms of the FIR-radio correlation of Wolf-Rayet galaxies. The AGNor starburst-supported LINERs can be distinguished by their FIR-to-radio ratio, Q ≡ L(1.4GHz)/ L(60μm) > or < 0.01. It is interesting to note that almost all the LINERs with inner rings might be starburstsupported, indicating reduced AGN activities com...

This paper tries to study the effect of geosynthetic inclusion on the improvement of the load-settlement characters of two layered soil. In addition, the effect of geogrid and geotextile in reduction of the required thickness of subbase layer in unpaved roads is studied. Considering the vast application of bearing ratio tests in road construction projects, this test is used in present investiga...

Backside wear due to micromotion and poor conformity between the liner and its titanium alloy shell may contribute to the high rates of retroacetabular osteolysis and consequent aseptic loosening. The purpose of our study was to understand the wear process on the backside of polyethylene liners from two acetabular cup systems, whose locking mechanism is based on a press-fit cone in combination ...

Our analysis on the two magnitude-limited samples of LINERs suggests a correlation between LFIR/LB or f(25μm)/f(60μm), and Hubble-type index at >99.99% significance level. As LFIR/LB and f(25μm)/f(60μm) are considered as the indicators of star-formation activity and AGN activity, respectively, our result suggests that LINERs with higher AGN activity may have a lower star-formation contribution....
