in isobaric models for inertial confinement fusion it is assumed that the target configurationat stagnation time (maximum compression) consists of two regions, hot spark and cold fuel, respectively.here the conditions of spark formation and ignition in hydrogen equimolar isotopes in central sparkignition are investigated and permissible values of hs and ts are evaluated numerically. by introduc...

in this study, ultrafine grained 2024 al alloy based b4c particles reinforced composite was produced by mechanical milling and hot extrusion. mechanical milling was used to synthesize the nanostructured al2024 in attrition mill under argon atmosphere up to 50h. a similar process was used to produce al2024-5%wt. b4c composite powder. to produce trimodal composites, milled powders were combined w...

to investigate the hot deformation behavior of 17-7 ph stainless steel, hot compression tests were carried out at the temperatures of 950, 1050 and 1150 oc and strain rates of 0.001 s-1 to 0.1 s-1. accordingly, the hot working behavior was studied by the analyses of flow stress curves, work hardening rate versus stress curves, exponent- type constitutive equations and deformed microstructures. ...

The undisputed optimum treatment for venous leg ulcers is compression therapy, where an external appliance (multilayer, short-stretch bandaging and compression hosiery) promotes venous return through graduated compression of the tissues and capillaries. However, this is not always acceptable to the patient, particularly when the patient's social life is affected with malodour and pain associate...

The compression of direct-drive, spherical implosions is studied using cryogenic D2 targets on the 60-beam, 351-nm OMEGA laser with intensities ranging from approximately 3x10(14) to approximately 1x10(15) W/cm2. The hard-x-ray signal from hot electrons generated by laser-plasma instabilities increases with laser intensity, while the areal density decreases. Mitigating hot-electron production, ...

New CO observations at the center of cooling flow in Perseus cluster [4] show a clear correlation of the molecular gas with the previously detected H-α filaments [1]. In this poster, we present high resolution multi-phase simulations of the Perseus Cluster, taking into account the AGN feedback in form of hot buoyant bubbles. These simulations show that significant amount of gas can cool far fro...

Surface plasmon polaritons are a central concept in nanoplasmonics and have been exploited to develop ultrasensitive chemical detection platforms, as well as imaging and spectroscopic techniques at the nanoscale. Surface plasmons can decay to form highly energetic (or hot) electrons in a process that is usually thought to be parasitic for applications, because it limits the lifetime and propaga...

The mechanical properties of the high-strength low-alloy pipeline steels were mainly controlled by the subsequent phase transformations after rolling. The influence of hot uniaxial compression on the phase transformation of acicular ferrite was explored by viewing of the deformation degree, the deformation temperature, and the strain rate. The results show that the increase of deformation amoun...
