Taschenbuch. Condition: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The present work deals with the studies on the corrosion Inhibitive action of inhibitor formulations containing organic and inorganic chemicals present in the materials used in our day to day life to inhibit corrosion. The inhibitors chosen for the present study are ethylene diamine tetra acetic acid (EDTA), 1-hydroxyethane-1,1-phosphonic acid (HEDP), Sodium phosphate (Na3PO4), Sodiumdodecyl sulphate(SDS), Phenylphosphonic acid (PhPA), Sodium sulphite (Na2SO3), Sodium nitrite (NaNO2), with Zinc sulphate.The biocides selected for the present work is N-Cetyl-N,N,N-trimethyl ammonium bromide (CTAB).The medium chosen for the study is double distilled water. The methods used for the study includes weight-loss methods, polarization studies, AC impedance, FTIR,UV absorption and fluorescence spectra. On the basis of results obtained from weight loss method, other studies are carried out. The problem due to micro organisms was studied by the use of biocide (CTAB). The experimental result show that all the seven inhibitors chosen exhibit synergism with Zn2+ ions for the corrosion inhibition of carbon steel in double distilled water is in the order, HEDP = Na3PO4 PhPA SDS NaNO2 Na2SO 316 pp. Englisch.…

Taschenbuch. Condition: Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Open source is an approach to design, development, and distribution offering practical accessibility to a product's source (goods and knowledge). A Geographic Information System is a system for management, analysis, and display of geographic knowledge, which is represented using a series of information sets such as maps, geographic data sets, processing and work flow models, data models, and metadata. Electoral GIS is an important information system to find out the voters list with their residential map and their addresses to check the correct address with their location. In present time, open source initiative has gained momentum and projects are being developed using open source products. Hence, an attempt is made to develop a GIS based application tool for Voter ID address verification with their residential maps. With the help of this application, people and officials can verify the address and solve the address mismatches. …
