Although the general complication rate for vertebroplasty is low, neural compression and thermal damage have been related to the use of polymethyl-methacrylate cement. This study focuses on the risk of thermal tissue damage after vertebroplasty. In this study, cavities were created by a transpedicular approach in the vertebral bodies (L3, L4, and L5) of four milk goats, and polymethyl-methacryl...

We have compared the rates of infection and resistance in an animal model of an orthopaedic procedure which was contaminated with a low-dose inoculum of Staphylococcus epidermidis. We randomised 44 Sprague-Dawley rats to have bone cement implanted subcutaneously containing either gentamicin or saline (control). The wound was inoculated with a dilute solution of gentamicin-sensitive Staphylococc...

The utilization of walnut shell (WS) as partial replacement aggregates and cement is getting more attention in modern research on construction material. Though WS provides lightweight concrete, but less compressive strength porous structure concrete still problematic for its utilization. Thus, this study using untreated powder (UWSP) ultra-fine treated ash (UFTWSA) a substitute cement. Differen...

This paper proposed a new method of exposing fibers using expandable polyethylene (EPE) foam to improve the interface performance. The flexural tensile behavior between precast steam-cured and cast-in-place non-steam-cured ultra-high performance concrete (UHPC) members was examined under four-point bending. improvement effects four non-destructive treatments—e.g., coating with epoxy glue cement...

BACKGROUND Polymethylmethacrylate bone cement cannot provide an adhesive chemical bonding to form a stable cement-bone interface. Bioactive bone cements show bone bonding ability, but their clinical application is limited because bone resorption is observed after implantation. Porous polymethylmethacrylate can be achieved with the addition of carboxymethylcellulose, alginate and gelatin micropa...

Creating new construction materials with improved strength, elasticity, and durability properties represent the focus of many research works. Significant effort has been invested in investigating use carbon nanotubes (CNTs) cementitious materials, especially multi-walled (MWCNTs) which consist a series concentric graphite tubes. The MWCNTs is closely related to surfactants ultra-sonication proc...

where R is the bend radius, and P the radiated power. This paper outlines the special issues for reaching subThe design of a synchrotron light source is essentially a nm emittance in a storage ring. Effects of damping matter of balancing the conflicting trade-offs (optimized wigglers, intra-beam scattering and lifetime issues, for Insertion Device (ID) beam lines) 161: dynamic aperture optimiza...

The advent of high quality PC based instruments, combined with the normal day to day skills of linear test engineers, eliminates the need for general purpose linear testers in many cases. Linear applications are dominated by custom DUT boards; therefore a few application card tricks and some PC instruments can replace the general purpose linear tester and significantly reduce cost and size with...

Peats are geotechnically problematic soil due to their high compressibility and low shear strength. Cement is widely used for the stabilization of peat by deep mixing method (DMM). This paper presents the results of the model study of compressibility property of peats stabilized with cement columns formed by DMM. The results of consolidation test, scanning electron micrographs (SEM) and energy ...

In many supercomputing applications, high data reference locality (HDL) allows hardware and software designers to reduce the impact of long data access latency through caching and migration techniques. Other applications (e.g., cryptography, data mining) exhibit low data reference locality (LDL), forcing system designers to pursue minimum data access latency using non-traditional techniques. Th...
