Yttrium barium copper oxide (YBCO) is a family of crystalline chemical compounds that display high-temperature superconductivity; it includes the first material ever discovered to become superconducting above the boiling point of liquid nitrogen [77 K (−196.2 °C; −321.1 °F)] at about 93 K (−180.2 °C; −292.3 °F).
The term "yBa" was already used in 1994 [8] and later used by Simon Ford in a feature "Myth Making" in March 1996 in Art Monthly magazine.

Homemade cranberry sauce. Sauteed or steamed green beans. Nuts. Seeds. Fresh fruit. Overall, Ali just recommends pacing yourself with Thanksgiving, while focusing on protein and veggies.
An impulse generator is an electrical apparatus which produces very short high-voltage or high-current surges. Such devices can be classified into two types: impulse voltage generators and impulse current generators.
As seasonal influenza ramps up, and with bird flu continuing to circulate, some public health experts are worried there may be a strain on the public health system. Since the bird flu outbreak ...
A linear alternator is essentially a linear motor used as an electrical generator. An alternator is a type of alternating current (AC) electrical generator. The devices are often physically equivalent. The principal difference is in how they are used and which direction the energy flows.
