along with 3 boiling chips. A thermometer was then suspended down the middle of the condenser to record the distillation temperature. The mixture was heated gently and a pure solvent started to collect in the distillation flask. Two different fractions were collected. The first one was the forerun‚ which was collected before the temperature stabilized and the second one was when the temperature of the boiling compound began to stabilize. The unknown impure organic A was identified using density

microplate reader the absorbance was measured at 595nm. A standard curve was created by plotting the absorbance (595nm) vs BSA (ug) data‚ and a best fit line was drawn. Then‚ absorbance readings at 595nm were triplicated using W1-W6 and E1-E6 sample fractions. Extrapolated the absorbance values on the standard curve and determined the amount of total protein that was present in the known volume of sample. (Source: See Lab

sum-of-the-year’s-digits method of depreciation calculation is configured by using the fraction formula. The fraction formula is computed by using the number of years of the item life cycle use as the numerator and the total years as the denominator. If the item life cycle is 5 years then the numerator in year one of depreciation will be 5 and 15(5+4+3+2+1) as the denominator the fraction would be 5/15. Which this is fraction is multiplied by the depreciable base of the item to conclude the year one depreciation

vernodalin‚ vernolide and vernomygdin‚ were identified as components of the cytotoxic extract (Kupchan et al.‚ 1969). Another study by Izevbigie (2003) evaluating the antitumour effect of the plant showed that the water-soluble leaf extract and fractions of V. amygdalina were potent inhibitors of cultured MCF-7 cells (human breast cancer cell model). Similar result was reported by Wong et al. (2013) of the 80 % ethanol extract on human breast cancer cell lines (MCF-7 and MDA-MB-231 cells) (Wong et

Spectral Range 0.010 cm-1 was used to resolve the fringes of the Hg 546.0731nm spectral line‚ and the 594.4834nm‚ 614.3063nm‚ 640.2246nm and 650.6528nm spectral lines of the Ne lamp‚ and study them at very high dispersion. Using the method of exact fractions‚ an extremely accurate value for the etalon spacing of d=15.077582±0.0000006mm was obtained. The spectral line widths (their full widths at half maximum intensity) of afore mentioned lines were examined‚ and factors affecting their line broadening
