Introduction In order to determine the content of calcium and magnesium in an unknown sample of limestone‚ the utilization of atomic absorption spectrophotometry can help in deciphering the unknown concentrations of each molecule in the limestone sample. Atomic absorption spectrophotometry‚ emits radiation of the correct frequency that is passed through a flame and the intensity of the transmitted radiation is measured¹.The calcium concentration or ppm can be measured using the absorbance of the

Introduction: Process costing is a form of operations costing which is used where standardized homogeneous goods are produced. This costing method is used in industries like chemicals‚ textiles‚ steel‚ rubber‚ sugar‚ shoes‚ petrol etc. Process costing is also used in the assembly type of industries also. It is assumed in process costing that the average cost presents the cost per unit. Cost of production during a particular period

Dissolution[edit] In the most common situation‚ a tablet is ingested and passes through the esophagus to the stomach. The rate of dissolution is a key target for controlling the duration of a drug’s effect‚ and as such‚ several dosage forms that contain the same active ingredient may be available‚ differing only in the rate of dissolution. If a drug is supplied in a form that is not readily dissolved‚ the drug may be released more gradually over time with a longer duration of action. Having a

INTRODUCTION: In atomic spectroscopy the samples are vaporized at 2000-8000k. The process of this involves two steps ‚ one is atomization of sample and the other is absorption of light radiation from light source. The atoms in the vapour are measured by absorption or emission at characteristic wave lengths. The main usage of this was to detect one element from another in the complex sample which has taken ie.‚ it has ability to perform multiple element analyses. Absorbance should obey Beer’s law

Marginal Costing Versus Absorption Costing The MAIN DIFFERENCE is the treatment of FIXED COSTS. This treatment can produce different profit figures.The two methods of costing produce different profit levels dependent upon the net change in the level of stock during the period.This is due to the VALUATION of the net change in stock during the period. In [...] Over/(Under) Absorption Of Overheads In earlier articles‚ we discussed about absorption costing‚ its advantages and disadvantages and

fixed‚ variable and semi-variable costs; differential incremental or decremental costs; opportunity costs etc. In the managerial decision making process‚ each classification has its own importance. Many costing techniques evolved in due course of time to ascertain the costs of above elements and to facilitate the control of the cost of the product. The main costing techniques that evolved include Absorption Cost Technique‚ Marginal Cost Technique and recently developed Activity Based Costing Technique

MARGINAL COSTING Introduction This paper explores the use of cost accounting information for decision-making purposes. DEFINITION OF KEY TERMS Marginal cost: This is the cost of a unit of a product or service‚ which would be avoided if that unit or service was not produced or provided Break-even point: This is the volume of sales where there is neither profit nor loss. 1 9 6 COST ACCOUNTING S T U D Y T E X T Margin of safety: This is the excess of sales over the break-even volume in
