A team of researchers at the University of Pittsburgh led by Dr Daniel Shiwarski has created a new tissue culture platform that mimics the natural cellular environment. They used biocompatible collagen and 3D printing technology. CHIPS enable the creation of realistic models of diseases such as diabetes and hypertension. They make it possible to eliminate the need for animal testing. Published in the prestigious journal Science Advances, the research shows that the new scaffolds could revolutio...

Dynamics or dynamic range is a parameter of a reflectometer that tells you about the measurement capabilities of the device in terms of maximum line attenuation. This parameter is expressed in dB and usually takes values in the range 20 dB - 40 dB. In simple terms, it tells you what maximum attenuation the measured line can reach before the noise in the reflectogram prevents any interpretation of the measurement. For example, a dynamic of 20 dB will in theory allow 50 km of fibre to be measured...

RACK cabinets have become the standard in multi-family buildings for the organisation of telecommunication installations. Thanks to their functionality, universal dimensions (19" width, various heights in U units) and aesthetics, they enable the orderly installation of devices such as multiswitches, amplifiers, network switches, power supplies or patch panels....

As a standard, devices responsible for home security (monitoring, intercom, gate controllers, etc.) and home computer equipment should not be located on the same IP network. The separation of these devices from each other is one factor in increasing the security of the security system.
