Electricity most materials is relatively constant over a range of temperatures and currents; materials under these conditions are known as 'ohmic'. The ohm, the unit of resistance, was named in honour of Georg Ohm, and is symbolised by the Greek letter Ω. 1 Ω is the resistance that will produce a potential difference of one volt in response to a current of one amp. The capacitor is a development of the Leyden jar and is a device that can store charge, and thereby storing electrical energy in the resulting field. It consists of two conducting plates separated by a thin insulating
Thymidine kinase 1 of malignancy, furthermore, TK-1 has been found to be elevated in serum even before clinical symptoms appear. This offers the potential for earlier therapy. Elevations in serum TK-1 have been found to correlate with the return of breast and other forms of cancer TK-1 can be used to detect cancer earlier, determine what stage it is in, and detect recurrence. Thymidine Kinase 1 can be measured based on its enzyme activity or using immunoassay. Thymidine kinase 1 Thymidine kinase 1, soluble (gene name TK1), is a human thymidine kinase. Two forms of this protein have been identified in animal cells,
