Pseudomonas aeruginosa, very common and widespread, is an opportunistic pathogen for man that causes antibiotic-resistive infections in persons of weakened resistance.
The result was the first "resistive" touch screen.
In standard silicon-based electronics, this involves the repeated application of resistive materials to protect those parts of the layer being etched that need to be preserved.
Then, by dint of another fundamental property of superconductors, they abruptly become resistive again, only to go back to business as usual when the surge dissipates.
This is made possible by the latest "giant magneto-resistive" (GMR) technology, laboratory versions of which can store as much as 1,450 megabytes a square inch.In this section Your mother was right (again) A byte of the action Feel the noise Jupiter's rings ReprintsHowever, despite such continuing triumphs of storage wizardry, the end is now in sight.
Scientists at the Centre for Magnetic Recording Research at the University of California, San Diego, have put shards of ground-up platters under a scanning magneto-resistive microscope and reconstructed traces of the original data.
Hewlett-Packard's scientists, however, have worked out how to print a layer of resistive material of variable height on top of all the other layers.
(For this reason PCM memory is sometimes called "resistive memory", and its individual cells are sometimes referred to as "memristors").You may already be relying on chalcogenides to store data without realising it, because they are used in re-writeable optical storage, such as CD-RW and DVD-RW discs.
Seawater is a much better conductor (i.e., it has lower resistivity) than fresh water owing to its higher content of dissolved salts; dry rock is very resistive.
Although ceramic ferrites have smaller saturation magnetizations than magnetic metals, they can be made much more resistive to electric currents.
The resistive force is the viscosity of the nonflowing solvent.
