INTRODUCTION Radiation‚ flow of atomic and subatomic particles and of waves‚ such as those that characterize heat rays‚ light rays‚ and X rays. All matter is constantly bombarded with radiation of both types from cosmic and terrestrial sources. This article delineates the properties and behaviour of radiation and the matter with which it interacts and describes how energy is transferred from radiation to its surroundings. Considerable attention is devoted to the consequences of such an energy

A removal process consisting of absorption‚ desorption‚ heat exchangers and auxiliary equipment is shown in Figure 10. Absorption is traditionally performed in a column with plates‚ random packing or structured packing. CO2 containing gas flows upwards and the absorption liquid flows downwards. The solvent (rich amine) is pumped further through a heat exchanger to a separation column. The absorbed CO2 is regenerated in a separation (stripper) column. Heat is added to the reboiler and a condenser

Concepts of Radiation Radiation * Emission of energy from an atom and the transmission of this energy through space. * Energy propagated in a material medium or space. * Energy in transit. What are the types of radiation? * Radiation is of two general types in our environment. * They are called non-ionizing and ionizing. Ionization * the energy transferred to the electrons causes them to be pulled away or removed from an atom entirely. * The result is the

Absorption costing: * It is costing system which treats all manufacturing costs including both the fixed and variable costs as product costs * In absorption costing‚ all costs are absorbed into production and thus operating statements do not distinguish between fixed and variable costs. * Absorption costing is a process of tracing the variable costs of production and the fixed costs of production to the product. Absorption costing is used to cost products and to report financial

Carlo is a mathematical method to solving real world problems using probability; it can be used to determine the most probable trajectory that individual particles will take after taking into account for the physical properties that govern the process (1). In this experiment Monte Carlo will be subjected to several different parameters to determine how these factors will affect real world particles. EGS (Electron Gamma Shower) code will be used to do the MC simulation‚ it is capable of producing

Introduction At any particular wavelength the absorption of light when visible light passes through a solution depends on two factors: * The length of the light path * The concentration of the colored path The connection of these two variables is known as the Beer-Lambert Law: Absorbance (A) = ε c l Where ε is the absorption coefficient C is the concentration of the compound And l is the length of light usually 1cm When I is constant‚ this proves a linear relationship between

Absorption Costing Absorption costing is a method of costing that assigns a small percentage of production and overheads costs to the price of each product that is going to be sold. It accounts for all costs‚ direct and indirect‚ fixed and variable. For example; if 1000 products are made and the total costs are £10000 then each product would cost £10 before making a profit (10000/1000=10). Variable costs are costs that can be controlled by management or a sales worker. Whereas fixed costs are

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
