similar pattern; however‚ spore-crystal complex formation of the indigenous Bt isolates was different with respect to the reference strain. The two indigenous isolates formed the maximum sporecrystal complex at 36 h‚ whereas the reference strain did the same at 66 h. Hence‚ the productivity of endotoxin formation of the indigenous isolates‚ 34.30 10-3 and 37.50 10-3 g/L/h respectively‚ were higher than that of the reference strain (21.37 10-3 g/L/h). Spore-crystal complex of the bacilli was recovered

INTRODUCTION Crystal methamphetamine 1 use among people in some First Nations communities (both in Canada and the United States) has evolved into an issue that is requiring more and more attention. Indicative of this‚ in July of 2005‚ the Assembly of First Nations (AFN in Canada passed a resolution specifica lly directed at this emerging issue. ) f 2 As a result o this resolution‚ the AFN has identified the n eed for the development of a First Nations National Task Force on Crystal Meth

Conclusion: 1. Write at least ten questions that you would like answered about this experiment. 1. What is the identity of Crystal “X”‚ Liquid “Y”‚ and Liquid “Z”? 2. Why were the colors different when Crystal “X” was added to Liquid “Y”‚ but when they were mixed it turned from green to blue? 3. Why did the metal foil turn brownish red once added to Crystal “X” and Liquid “Y” solution? 4. Were Liquid “X” and Liquid “Y” the same liquid? 5.What chemical reaction happened that made vapor

and optical computing etc. The author has successfully grown ZTS crystal by gel method. Gel technique has been adopted at ambient temperature to attain better result. The grown crystals were transparent and colourless. The crystal size has been obtained the range about 5mm X 3mm X 2mm.

experimental technique that exploits the fact that X-rays are diffracted by crystals. It is not an imaging technique. X-rays have the proper wavelength (in th Å t ö (i the Ångström range‚ ~10-10 m) t be scattered by the electron cloud of an atom of 10 10 ) to b tt d b th l t l d f t f comparable size. Based on the diffraction pattern obtained from X-ray scattering off the periodic assembly of molecules or atoms in the crystal‚ the electron density can be reconstructed.

K-feldspars will seperate from the albite in a process called exsolution. The albite will form layers inside the k-feldspars crystals. Some times these layers are discernable to the naked eye and the stone is referred to as perthite. Albite by definition must contain no less than 90% sodium and no more than 10% of either potassium and/or calcium in the cation position in the crystal structure.. Albite is the last of the feldspars to crystallize from molten rock. The process of crystallization from
