BACKGROUND The method of attachment of prosthesis to the residual limb (suspension) and socket fitting is a critical issue in the process of providing an amputee with prosthesis. Different suspension methods try to minimize the pistoning movement inside the socket. The Seal-In(®) X5 and Dermo(®) Liner by Ossur are new suspension liners that intend to reduce pistoning between the socket and line...

The fossil record of Peronosporomycetes (water moulds) is rather sparse, though their distinctive ornamentation means they are probably better reported than some true fungal groups. Here we describe a rare Palaeozoic occurrence of this group from a Guadalupian (Middle Permian) silicified peat deposit in the Bainmedart Coal Measures, Prince Charles Mountains, Antarctica. Specimens are numerous a...

We have designed a three dimensional (3D) fluorescence optical tomography system for small animal imaging based on an innovative system geometry that uses a truncated conical mirror which permits the entire surface of the animal to be viewed simultaneously by a single CCD camera. Compared with traditional approaches that employ a flat mirror, the conical mirror system has approximately 3 times ...

The fermion condensate (FC) is investigated for a (2+1)-dimensional massive fermionic field confined on truncated cone with an arbitrary planar angle deficit and threaded by magnetic flux. Different combinations of the boundary conditions are imposed edges cone. They include bag condition as special case. By using generalized Abel-Plana-type summation formula series over eigenvalues radial quan...

A dual mobility acetabular component has a structure that combines a polyethylene liner and a femoral head, unlike the general design of acetabular cups, making the dissociation of a polyethylene liner highly unlikely. In addition, it increases the range of motion and reduces the possibility of dislocations by increasing a jump distance. A fifty-one-year-old male who had received total hip arth...

We present a case of a 71-year-old woman with unexplained instability of her total hip arthroplasty 12 years after implantation due to loosening of the ceramic component of a sandwich ceramic in polyethylene liner. She experienced in total 2 dislocations in 6 months. These events occurred without fracture of the ceramic liner. Sandwich ceramic liners were introduced with the idea of combining t...

Liner design is becoming an increasingly more important tool for the AG/SAG mill performance optimization. The Gol-E-Gohar iron ore concentration plant uses three 9 m × 2.05 m autogenous mills (AG) in parallel in a dry operation. Due to large variations in feed characteristics and inadequate blending, the performance of AG mills has been lower than the target value. In order to increase the cir...

OBJECTIVE To compare a seal-in liner with the common suction socket with regards to patient satisfaction and problems experienced with the prosthesis. DESIGN Retrospective survey. SETTING A medical and engineering research center and a department of biomechanical engineering. PARTICIPANTS Men (N=90) with traumatic transfemoral amputation who used both suspension systems participated in th...

We present an XMM-Newton observation of the Seyfert-LINER galaxy NGC 7213. The RGS soft X-ray spectrum is well fitted with a power law plus soft X-ray collisionally ionised thermal plasma (kT = 0.18 −0.01 keV). We confirm the presence of Fe I, XXV and XXVI Kα emission in the EPIC spectrum and set tighter constraints on their equivalent widths of 82 −13, 24 +9 −11 and 24 +10 −13 eV respectively....

The Code of Federal Regulations (CFR) defines performance based technical criteria for solid waste landfill liner design alternatives in terms of predicted impacts to groundwater as the basis for approval by the Director of an approved State. This approach first requires the designer to estimate the amount of leakage through the liner system into the unsaturated subsurface vadose zone below the...
