The effective medium approach to radial fixed bed dispersion models, in which radial dispersion of mass is superimposed on axial plug flow, is based on a constant effective dispersion coefficient, DT. For packed beds of a small tube-to-particle diameter ratio (N), the experimentally-observed decrease in this parameter near the tube wall is accounted for by a lumped resistance located at the tub...

In this work, thermo – elastic analysis for functionally graded thick – walled cylinder with temperature - dependent material properties at steady condition is carried out. The length of cylinder is infinite and loading is consist of internal hydrostatic pressure and temperature gradient. All of physical and mechanical properties expect the Poisson's ratio are considered as multiplied an expone...

Vertical drains and stone columns which have been used in infrastructure construction for highways, ports, coastal regions, etc., provide significant benefits for improving soil characteristics such as reducing the drainage length and accelerating the consolidation process. So the investigation of the radial consolidation is inevitable. Soils may be subjected to cyclic loading such as silos, ta...

In order to determine the age structure, growth, and length-weight relationship of the mudskipper, Periophthalmus waltoni, from coastal mudflats of Qeshm Island, Soroo and Bandar-pol, in Hormuzgan Province, Iran, we collected 192 individuals in February 2007. Age was determined using the second pectoral radial bone and year class was based on length-frequency distributions. Growth was descr...

The radial propagation of type-I ELMs in ASDEX Upgrade has been measured using a number of techniques. The most reliable technique uses a filament probe to measure the time difference between two separated probes and yields a mean radial velocity obtained of ~1.5 kms -1 . The radial velocity calculated using a time of flight technique suffers from uncertainties in the start time and yields radi...

..Objective: To assess the radiological and functional outcome of external fixator in the treatment of intar-articular fractures of distal radius. Study design: Descriptive case series. Place and duration of study: Orthopaedic unit District Headquarter Hospital Temargarha Lower Dir from March 2013 to March 2014. Material and methods: Twenty five patients of intra-articular fracture distal radiu...

BACKGROUND Knowledge of the size and shape of radial head is essential for construction of radial head prosthesis. Further, the measurements of bicipital tuberosity and its angular relationship to radial head are significant in surgical techniques, like in the reconstruction of biceps tendon. Even the morphometry of the distal radius is significant in numerous clinical orthopedic situations suc...

Learning Objective We have presented a rare case of iatrogenic radial AVF after PCI which was unsuccessfully treated with thrombin PE, followed by a surgical resection. Radial artery is an effective access site for coronary catheterization and PCI with additional benefits of lower incidence of postprocedural complications, shorter length of hospital stay and reduced patient costs when compared ...
