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.
A typical industry laboratory method for determining residual oil sa turation in core analysis, API (1998) specifies a rock core be completely saturated with the non-wetting phase (oil displacing water) often by applying oil pressures in the range of 500 to 1000 psi (approx. 2,300 ft of water), refer to Figure 1.
