Water Disinfection Chlorine and Ozone‚ Which is More Efficient The use of chlorine and ozone in water disinfection is prevalent throughout the modernized world. Both options allow us to take water that was previously thought unusable and to change it into potable water. These options allow us to eliminate chemicals‚ microorganisms and disease from water such as cholera‚ e-coli‚ cryptosporidium‚ giardia‚ enterovirus‚ and many more including metals. There are pros and cons to both treatment processes

It was concluded that the product created was paracetamol when a thin layer chromatography test was performed and observed under ultraviolet light (which is discussed further down the page). An unknown substance was treated with acetic anhydrate and resulted with paracetamol. A compound that behaves in this matter is 4-aminophenol and is widespread in the industrial production of this drug. Upon these observations was the build up of “Chemical A” decided. When 4-aminophenol is t treated with

This paper will also discuss common practices for securing applications. The three main aspects of information security

contrary‚ in rigid pavements‚ wheel loads are transferred to sub-grade soil by textural Strength of the pavement and the pavement acts like a rigid plate (e.g. cement concrete roads). In addition to these‚ composite pavements are also available. A thin layer of flexible pavement over rigid pavement is an ideal pavement with most desirable characteristics. However‚ such pavements are rarely used in new

Data Link Layer INTRODUCTION: Now a day’s communication is vital for the entire world‚ nothing happens without communication. The cell radio communication and wireless computer networks of GSM (Global System Mobile)‚ CDMA (Code Division Multiple Access) type are worldwide communication systems. All these communication systems are based on the reference model OSI-RM (Open System Interconnection-Reference Model) Description of OSI-RM System: OSI-RM is an International Standard ISO that defines

Layers of the Grand Canyon During the earliest periods of the Grand Canyon formation where we have Tapeats sand stone‚ bright angel shale and muav limestone it would appear that there was a relatively shallow‚ warm sea. This is indicated by the presence of Trilobite fossils found in this layer which thrived in that environment. Trilobites were early animals that had exoskeletons that are usually the only part of them that is preserved in the fossil record. They were marine bottom feeders who thrived

the slurry to be placed on the glass plates. A guide allows the applicator (with an adjustable layer thickness gauge) to be pulled along the glass plates as the slurry is dispensed. Some practice is needed to get a continuous body motion pulling the applicator across the plates to get an even layer. The glass plates must be the same thickness and extremely clean. Any oil or grease will result in a poor layer. Handle the plates with rubber gloves when washing or rinsing. Care is also needed if the edges

unknown amino acid. Within experimental error‚ the results were consistent with the reference literature cited in this report. Experimental Thin Layer Chromatography The amino acid standards used in this experiment were Alanine‚ Glycine‚ Serine‚ and Histidine. These standards and the unknown were separated by performing a method of chromatography. Thin layer chromatography (TLC) was performed by using a mobile phase and a stationary phase. The mobile phase was a nonpolar solvent composed of ethanol
