Water Purification What is water purification? Water purification generally means freeing water from any kind of impurity it contains, such as contaminants or micro organisms. Water purification is not a very one-sided process; the purification process contains many steps. The steps that need to be progressed depend on the kind of impurities that are found in the water. This can differ very much for different types of water. In which ways is polluted water treated? Settling Before the purification process begins some contaminants, such as oil, can be settled in a settling tank. They can then be removed easily, after they have reached the bottom of the tank. Removal of dangerous microorganisms Often polluted water has to be freed from microorganisms. The water is than disinfected, usually by means of chlorination. Removal of dissolved solids Microrganisms are not only a threat to water; they can also be an advantage when it comes to ...

TOPICS FOR SPEAKING CYLINDER FRAME The cylinder section of the engine consists of a number of cylinder blocks, which are tightened together with the engine frame and the bedplate by means of through- going stay bolts. Two central bores, one at the top and one halfway down inside the cylinder block, enclose the cylinder liner. The upper part of the cylinder block forms part of the cooling water space around the central part of the cylinder liner, whereas the lower part forms the scavenge air space. A central bore in the bottom of the cylinder block encloses the piston rod stuffing box. The bottom is double with a hollow space through which cooling water is circulated. On the exhaust side of the cylinder block there is a circular opening leading into the longitudinal scavenge air receiver of the engine. Furthermore, there is an inlet pipe for cooling and lubricating oil. The cylinder block is provided with cleani...

Intragenomic Profiling Using Multicopy Genes: The rDNA Internal Transcribed Spacer Sequences of the Freshwater Sponge Ephydatia fluviatilis Liisi Karlep, To~nu Reintamm, Merike Kelve* Department of Gene Technology, Tallinn University of Technology, Tallinn, Estonia Abstract Multicopy genes, like ribosomal RNA genes (rDNA), are widely used to describe and distinguish individuals. Despite concerted evolution that homogenizes a large number of rDNA gene copies, the presence of different gene variants within a genome has been reported. Characterization of an organism by defining every single variant of tens to thousands of rDNA repeat units present in a eukaryotic genome would be quite unreasonable. Here we provide an alternative approach for the characterization of a set of internal transcribed spacer sequences found within every rDNA repeat unit by implementing direct sequencing methodology. The promi...
