In recent years, timing RPCs (Resistive Plate Chambers) [1] have emerged as a novel, cost-effective technology to achieve high timing resolutions σt≤100 ps as well as high granularities, which are required for high particle multiplicities. In order to cope with rates of Φ≤700 Hz/cm (expected for Au+Au collisions), the HADES detector is being upgraded. As a part of the upgrade project, an RPCbas...

Studies were made with CBA T6T6 the 30-day recovery of marrow irradichimeras to evaluate the contribution ated with 1000 rad. Thus, these findof migrating cells to the recovery of ings provide a direct demonstration of x-irradiated marrow. It was observed the generally accepted inference of that cell migration from a shielded limb stem cell migration from unirradiated is essentially entirely re...

Placing shields around a victim signal line is a common way to enhance signal integrity while minimizing delay uncertainty. An analytic model of the peak noise is developed for shielded interconnects based on a model. A design methodology for inserting shields between coupled interconnects to reduce crosstalk noise is presented.

The paper presents the method of the argon - shielded hot pressing of titanium alloy (Ti6A14V) powder (used in medical industry). The powders produced in the GA (gas atomization) process and in the HDH (hydride - dehydride) process were used in the experiments. A pressing process was conducted at a temperature of 800-850 degrees C for different lengths of time. An unoxidized sintered material, ...

We perform radiation hydrodynamics simulations on the evolution of galactic gas disks irradiated by ultraviolet radiation background. We find gas disks with NH & 10 cm exposed to ultraviolet radiation at a level of I21 = 1 can be self-shielded from photoheating, whereas the disk with NH . 10 cm cannot. We also find that the unshielded disks keep smooth density distribution without any sign of f...
