(b) Suppose a larger equivalence study is planned. ![]() Can the new drug be considered equivalent to ibuprofen if the criterion for equivalence is that ibuprofen is no more than 5 % 5 \% 5% higher in efficacy than the new drug and a one-sided 90 % C l 90 \% \mathrm 90% Cl is used to establish equivalence? Ninety of the ibuprofen patients and 86 of the new drug patients show efficacy from the treatment. (a) To assess equivalence, a study is performed with 100 patients receiving each drug. The goal is that the drug will be equivalent to ibuprofen in efficacy but with fewer side effects. It basically tells us the rate of change of energy of light that falls onto some surface area. The illuminance of visible light is defined as the luminous flux per unit area. A new drug is proposed for patients with osteoarthritis. The luminous intensity is defined as the luminous flux per solid angle and it expresses the directionality of the energy radiated by the light. Intensity of a beam of light is defined as the power per unit cross section, and is measured in watts rn-2 or einsteins m-2 sec-1. Luminous flux, luminous power v: lumen ( candela steradian) lm ( cdsr) J: Luminous energy per unit time Luminous intensity: I v: candela ( lumen per steradian) cd ( lm/sr) J: Luminous flux per unit solid angle: Luminance: L v: candela per. A source of one candle gives off a luminous flux of one candle power or 4 lumens. Candela: this is the unit of measurement of luminous intensity, its abbreviation is cd. ![]() One possible side effect of the drug when taken for a long period of time is gastric bleeding. Luminous energy: Q v: lumen second: lms T J: The lumen second is sometimes called the talbot. Suppose ibuprofen is effective in 90% of patients. The luminous intensity of a light source is distinct from its. The drug ibuprofen is often used by patients with osteoarthritis to reduce inflammation and pain. It is expressed as a unit of candela (cd) and is measured according to the V luminosity function.
