Digitalis lactone and a triple-repeating sugar called a glycoside. Digitalis works by inhibiting sodium-potassium ATPase. This results in an increased intracellular concentration of sodium ions and thus a decreased concentration gradient across the cell membrane. This increase in intracellular sodium causes the Na/Ca exchanger to reverse potential, i.e., transition from pumping sodium into the cell in exchange for pumping calcium out of the cell, to pumping sodium out of the cell in exchange for pumping calcium into the cell. This leads to an increase in cytoplasmic calcium concentration, which improves cardiac contractility. Under normal physiological conditions, the cytoplasmic calcium used in
Tyseley Energy from Waste Plant Tyseley Energy from Waste Plant Tyseley Energy Recovery Facility is a waste incineration plant in Birmingham, UK. It is run by Veolia. It was built in 1996 by Veolia to a design by Faulks Perry Culley & Rech. The plant has become a notable building in Birmingham with a lighting scheme that illuminates the plant during the hours of darkness. It was built to comply with the European emissions standards that came into force in 1996. Veolia benefits from Levy Exemption Certificates for the element of energy which is produced from renewable sources. This provides income to the City Council.
