    When will profits reported under variable and absorption costing differ? How can we reconcile the profits reported under the two approaches? Profits reported under variable and absorption costing will differ when inventory increases or decreases during the year. The difference involves the timing with which fixed manufacturing overhead becomes an expense. Under variable costing‚ fixed overhead is expensed immediately as it is incurred. Under absorption costing‚ fixed overhead is inventoried until

    New forensic laser technique for hair analysis Using a new laser technique‚ Jim Moran and his colleagues at Pacific Northwest National Laboratory‚ have devised a method of separating out the parts of hair samples that can reveal details about the recent history of the person to whom it belongs. In their paper‚ published in Rapid Communications in Mass Spectrometry‚ they describe a process they’ve devised whereby hair samples are pulled apart‚ rather than burned as a whole before being measured

    (III) chloride were synthesized and isolated. From the ultraviolet-visible spectrum‚ infrared spectrum‚ and molar conductivity each compounds was distinguished and characterized to show fundamental differences between the three. Furthermore‚ IR spectroscopy is suitable for distinguishing between the nitro- and nitrito-linkage isomers because they have different vibrational patterns from one another. Given enough time‚ the more stable thermodynamic linkage isomer [Co(NH3)5NO2]Cl2 will be formed as

    Variable costing and absorption costing are the two most commonly used methods of inventory costing for manufacturing companies. The inventory method of variable costing takes place when total direct and indirect variable manufacturing costs are included within inventoriable costs. Fixed manufacturing costs however‚ are considered costs of the period under variable costing. The next method of inventory costing‚ absorption costing‚ includes all variable manufacturing costs as well as fixed manufacturing

    Absorption and Variable Costing‚ Inventory Management Absorption and Variable costing are very important tools for cost accounting. Both of these costing methods allow you to see the cost of your inventory‚ in a different way. For example the absorption method allows you to assign all costs to the product‚ while variable costing allows only variable costs to be assigned to the product. Inventory management is extremely important as well because it ties into efficiency and lowering your costs

    Introduction What is Protein? There are more than 300 amino acids in the nature. However‚ only 20 amino acids are joined by each other with peptide bonds in different sequences and numbers. These sequences are formed by helping of genetic information which is encoded in genes. So‚ each protein molecule has its own amino acid sequence. Proteins are most abundant long chain macromolecules in all cells and they serve as structure and function matter in cells of all living organisms such as hormones

    DATE PERFORMED: JANUARY 6‚ 2011 SPECTROPHOTOMETRIC DETERMINATION OF THE EQUILIBRIUM CONSTANT OF A REACTION ABSTRACT The objective of the experiment was to determine the equilibrium constant of the reaction forming ferric thiocyanate through the use of Spectrophotometry. For the calibration‚ five standard solutions were prepared‚ then their respective absorbance values that were obtained through the use of the spectrophotometer‚ were plotted versus the concentration of the analyte so that a calibration
