more than 50 references covering the wide scale of heterogeneous water phase applications. Finally, a short review of more interesting practical application of photocatalysis for the removal of natural organic matter from seawater is presented. 1. INTRODUCTION Heterogeneous photocatalysis is a rapidly expanding technology for water and air treatment. It can be defined as the acceleration of photoreaction in the presence of a catalyst. The initial interest in the heterogeneous photocatalysis was started

[pic] ✓ INTRODUCTION ✓ ALLOTROPHIC FORMS OF CARBONS ✓ APPLICATIONS Carbon from Latin: carbo "coal" is the chemical element with symbol C and atomic number 6. As a member of group 14 on the periodic table, it is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. There are three naturally occurring isotopes, decaying with a half-life of about 5,730 years. Carbon is

INTRODUCTION Review of Related Literature Pneumonitis Pneumonitis is a general term that refers to inflammation of lung tissue. It occurs when some irritating substance – solid particles, liquids, gases, radiation or bacteria – cause the tiny air sacs to become inflamed. This can hamper the exchange of oxygen and carbon dioxide in the air sacs. Pneumonia is one type of pneumonitis caused by an infection. There are several types of pneumonitis. They include: • Aspiration pneumonitis-

FUNDAMENTALS OF GAS TURBINE ENGINES INTRODUCTION The gas turbine is an internal combustion engine that uses air as the working fluid. The engine extracts chemical energy from fuel and converts it to mechanical energy using the gaseous energy of the working fluid (air) to drive the engine and propeller, which, in turn, propel the airplane. THE GAS TURBINE CYCLE The basic principle of the airplane turbine engine is identical to any and all engines that extract energy from chemical fuel. The basic

| Environmental pollution is “the contamination of the physical and biological components of the earth/atmosphere system to such an extent that normal environmental processes are adversely affected” Pollution is the introduction of contaminants into the natural environment that causes adverse change. Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies
