LLE Review, Volume 143 125 Introduction In inertial confinement fusion (ICF),1 a shell of cryogenic deuterium (D) and tritium (T) filled with DT gas is imploded with direct laser illumination (direct drive)2 or through an x-ray bath produced inside a laser-irradiated hohlraum (indirect drive).3 Energy from the laser or x ray is absorbed in the plasma near the outer surface of the target, causin...

Parotid fistula is a rare complication of surgical or non-surgical trauma on or in the vicinity of parotid gland. Many pharmacological agents and surgical methods are used to treat it with their own merits, demerits and patient preferences. Injection of hypertonic hot saline along with compression dressing is an economical, patient-preferred and almost complication-free method to deal parotid f...

Pelletization is an agglomeration process that converts fine powders or granules of bulk drugs and excipients into small, free flowing, spherical or semi-spherical units, referred to as pellets. This review outlines manufacturing of spherical pellets. The manufacturing techniques include Drug layering, Extrusion-Spheronization, Cryopelletization, Compression, Balling, Hot-Melt Extrusion Technol...

We have studied the fate of initial magnetic fields in the hot halo gas out of which the visible parts of galaxies form, using threedimensional numerical MHD-experiments. The halo gas undergoes compression by several orders of magnitude in the subsonic cooling flow that forms the cold disk. The magnetic field is carried along and is amplified considerably in the process, reaching μG levels for ...

A supernova explosion, the final death throe of a massive star, creates an expanding bubble of hot gas that overruns up the surrounding medium. When a supernova remnant encounters a dense interstellar cloud, the compression may trigger gravitational collapse and the formation of a new generation of stars. This event can be detected through intense stimulated emission in the 1720-megahertz trans...

This class reviews new functionality in Autodesk Simulation Moldflow Insight software and discusses recent and current research directions of Moldflow development. We cover the following capabilities: viscoelastic warp calculations, improved wall slip calculations, the influence of mold deflection, ejection force predictions, analysis of mold fatigue, flow imbalances (airflow), 3D compression m...

The hot deformation behavior and microstructural evolution of Ti-44Al-5V-1Cr alloy were investigated by hot compression tests at temperatures of 1000–1250 ◦C and strain rates of 0.001–1 s−1. It was indicated that the dependence of peak stress on deformation temperature and strain rate could be accurately described by a hyperbolic sine type equation. The activation energy, Q, was estimated to be...

The compression process in a piston cylinder device in a Compressed Air Energy Storage (CAES) system is studied computationally. Twelve different cases featuring four different compression space length-to-radius aspect ratios and three different Reynolds numbers are studied computationally using the commercial CFD code ANSYS FLUENT. The solutions show that for compression with a constant veloci...

Among the titanium alloys, Ti-6Al-4V is the most widely used. In the present work, the uniaxial hot compressive behavior of Ti-6Al-4V has been investigated under constant strain rates. A series of dilatometery experiments were carried out to determine the transformation temperatures at different cooling rates. Specimens were homogenized at 1050 °C for 10 minutes followed by fast cooling to dif...

percutaneous vertebroplasty is a promising therapeutic technique for pain control in patients with pathologic fractures of vertebral bodies. percutaneous vertebroplasty is an appropriate treatment for vertebral pathologic fractures, which is resistant to other usual treatment. it is a useful and only choice in special cases, because of less tissue damage and there is no risk of open surgery and...
