Study On Shrimp Farming Technique In Gujarat State

Shrimp farming has been practiced in India for centuries on a traditional manner in certain coastal state. Scientific shrimp farming was developed during the early 1980s. Thousands of hectares of coastal lands were converted into shrimp farming. Shrimp farming activities in Gujarat state are also not uncommon at present.  Gujarat is having 1,600 km long coastline and a vast stretches of brackish water area throughout the coastline which is ideal for shrimp culture.  Shrimp farming activities developed fast in the last decade.

STRUCTURAL, OPTICAL AND ELECTRICAL PROPERTIES OF TITANIUM DIOXIDE NANOPARTICLES

Structure of calcinated TiO2 has been examined by X-ray diffraction (XRD) and Scanning Electron Microscope (SEM) analysis. The formation of the single phase TiO2 was confirmed by X-ray diffraction (XRD) and the structural parameters were refined by the Rietveld analysis. A good agreement between observed and calculated X-ray diffraction pattern was obtained from the Rietveld refinement using space group I 41/ amd. The calculated unit cell parameters are used to plot the structure.
