The luminosity upgrade of the large hadron collider (SLHC) at CERN will require the innermost layers of the vertex detectors to achieve excellent performances up to fluences of about 10 hadrons cm . New solid state detectors are currently being developed by the CERN RD50 collaboration. In this paper recent results on magnetic Czochralski, epitaxial, and oxygen-enriched silicon will be presented...

Purpose: To explore areas in which the education at the Pakistan Institute of Prosthetic & Orthotic Science (PIPOS) could be improved or supplemented to facilitate clinical practice of graduates. To describe educational opportunities PIPOS graduates have had since their graduation and explore their further educational needs. Method: 15 graduates from PIPOS participated in semi-structured interv...

introduction: stromal cells having preadipocyte characteristics can be isolated from adipose tissue, propagated in vitro and induced to differentiate in vitro toward the osteogenic, adipogenic, myogenic and chondrogenic lineages when treated with established lineage-specific factors. in this research we isolated stromal cells from human adipose tissue and cultured and expanded and examined thei...

We give a short review on the semi-analytic approach to off-shell W pair production at 500 GeV and above. Numerical calculations are performed with the Fortran program GENTLE v. 2.0 and its upgrade. Recent extensions include: (i) angular distribution for the CC11 process with LLA QED corrections; (ii) anomalous couplings. As an application we study the sensitivity of total cross-section and for...

The present paper explores the impact of an on-board hydrogen harvesting system (fuel reformer) on the overall efficiency of a fuel-cell powered vehicle. Various methods of hydrogen production for automotive applications have been discussed first. As the hydrogen production is one of the major challenges for application of proton exchange membrane (PEM) fuel cells, especially in vehicular indus...

The steady–state operation of the autothermal reformer is simulated as two reactors in series by means of a detailed mathematical model. An input-output model is selected to describe the upper combustion chamber. The possible occurrence of homogeneous steam reforming and watergas-shift (WGS) reactions is considered. The catalyst bed is represented through a one-dimensional heterogeneous model, ...
