Pediatric acetabular fractures are rare, and anterior column fractures are even rarer. Generally, conservative treatment is applied. If there is displacement of more than 2 mm or findings of instability or fragments within the joint, then surgical treatment is applied. Anterior and posterior approaches may be used in surgical treatment. With pediatric patients, even greater care should be taken...

THIS ISSUE’S COLUMN reports on papers (and a talk) from the 19th International Conference on Software Product Lines, the 10th Joint Meeting of the European Software Engineering Conference and the ACM SIGSOFT Symposium on the Foundations of Software Engineering, the 23rd IEEE International Requirements Engineering Conference, and the 9th European Conference on Software Architecture. Feedback or ...

This article evaluates and compares the punching shear behaviour of unbonded prestressed concrete (UPC) slab - concrete-filled steel tube (CFT) column connections/joints with that reinforced (RC) connection – CFT connections. The experimental program was carried out on five large-sized samples, including three UPC samples two RC samples. Steel plate details were utilised to increase bond betwee...

This study focuses on the functionalized modification of Ti-6Al-4V and CoCrMo alloys substrates widely used by biomedical domain as total joint replacements (TJRs) hip knee. To improve corrosion resistance these devices, nanostructured columnar zirconium (Zr) thin films were produced oblique angle deposition (OAD) using DC magnetron sputtering to model particular design joint. The influence ang...

The better the seismic performance of building joints, more lives and property can be preserved in earthquake disasters. This paper briefly introduced the basic structure self-centering reinforced concrete (RC) column-steel beam joints then prepared three types joint specimens. Specimen 1 was a self-centering RC column-steel joint, specimen 2 obtained by removing dampin...

A new algorithm is developed for independent component analysis (ICA) with or without constraints on the mixing matrix. The algorithm is based on the criterion of Joint Approximate Diagonalization of Eigen-matrices (JADE). We propose a column-wise processing approach to perform joint diagonalization of the cumulant (eigen-) matrices. Instead of successively selecting paired columns of the unita...

This research is designed to check the potential of modifying concrete with nanomaterials enhance cyclic behavior beam?column joints. It also studies effect heat on joints modified nanomaterials. Experimental and numerical programs are carried out explore heat-damaged unheated RC Six half-scale exterior beam-to-column were prepared; two control specimens, specimens nano-silica nano-alumina, nan...

Pigmented villonodular synovitis (PVNS) is an uncommon lesion nearly always occurring in the large synovial joints of the extremities. Involvement of the vertebral column is rare , having been previously reported only four times. The present report describes the myelographic and postmyelographic CT appearance of PVNS arising from a lumbosacral facet joint and extending within the spinal canal a...

Contracted services have gained greater emphasis in the home care standards and survey process over the past several years, especially as they relate to the quality and safety of the services provided. This column reviews 2004-2005 standard LD.3.50, its applicable elements of performance, and discusses the Joint Commission's requirements for evaluating the care and services provided by contract...
