diamonds are not lab-created diamonds. They’re cubic zirconia‚ which can still be incredibly beautiful and a great replacement for a high-priced diamond. The Nexus simulant costs less than a cubic zirconia of the same size. It has a hardness of 9.1 compared to CZ’s hardness‚ which is an 8.5 on the Mohs scale. A Nexus simulant doesn’t have the coating that’s available in the Asha simulant‚ but the proprietary simulant has the ability to stay clear and sparkling for years. Diamond Nexus Labs was started

The dissolution of the drug in different liquisolid formulations was performed in 500 ml simulated salivary fluid (phosphate buffer pH 6.8) maintained at 37 ± 0.5 ºC using the USP dissolution tester apparatus II‚ at a rotation speed of 50 rpm. Aliquots from the dissolution medium were withdrawn at 1‚ 2‚ 3‚ 4‚ 5‚ 6‚ 7‚ 8‚ 9‚ 10‚ 12.5‚ 15‚ 20‚ 25 and 30 minutes time intervals. The samples were changed with fresh dissolution medium of same amount to maintain a constant volume in the vessels. Samples

But why? Why cant a ruby be our best friend? Why cant the man of your dreams get you an 2.5 carat Sapphire ring when he pops the question? Would you say no if it wasn’t a diamond? Due to the clever marketing team of De Beers‚ they have made

Characterization Adam Bede Adam Bede is the hero of George Eliot’s novel ADAM BEDE. He is close-pin portrait of the novelist’s own father. George’s father‚ Robert Evans‚ began his working life as apprentice carpenter then “he raised himself from being artisan to be a man whose extensive knowledge is very varied”. When the novel opens‚ Adam Bede is introduced to us as a carpenter and foreman in Burger’s shop. George Eliot describes Adam as “not average man yet such men as he is reared here

Metals and alloys for nuclear energy There are two important ways in the making of nuclear energy: nuclear fission and nuclear fusion. Fusion and fission have a different working mechanisms‚ thus other materials are used. In a nuclear reactor fuel rods are bombarded with neutrons causing fission of the fuel. This way energy is released. With this energy water is heated to steam and with the use of heat exchangers and steam turbines electricity is generated. As fuel is usually uranium used‚ but also
