BROVANA Â® (arformoterol tartrate) Inhalation Solution is a long-acting beta 2-adrenergic agonist (LABA) indicated for the long-term, twice-daily (morning and evening) maintenance treatment of bronchoconstriction in patients with chronic obstructive pulmonary disease (COPD), including chronic bronchitis and/or emphysema.
The oil drop experiment was performed by Robert A. Millikan and Harvey Fletcher in 1909 to measure the elementary electric charge (the charge of the electron). The experiment entailed observing tiny electrically charged droplets of oil located between two parallel metal surfaces, forming the plates of a capacitor.
How does oil transfer energy? The hydrocarbon molecules in petroleum contain a large amount of chemical energy. When they are burned, two things happen: they release a lot of that energy as heat, and they release gases (carbon dioxide, water vapor and sometimes nitrogen, depending on the fuel).
