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.
These pages are NOT to be taken as gospel. The primary motivation behind this study was to provide information about what oil filter brands are made by which manufacturers. The secondary motivation was to uncover some of the obvious internal construction issues of these manufacturers. This study is not a test. The SAE J806 and J1858 tests were designed to test the filtration capability of these filters, but unfortunately they have several short comings.
