Separation efficiency of a vacuum gas lift for microalgae harvesting.

Low-energy and low-cost separation of microalgae from water is important to the economics of microalgae harvesting and processing. Flotation under vacuum using a vacuum gas lift for microalgae harvesting was investigated for different airflow rates, bubble sizes, salinities and harvest volumes. Harvesting efficiency (HE) and concentration factor (CF) of the vacuum gas lift increased by around 5...

Microstructural Study on Molten Marks of Fire-Causing Copper Wires

Although electrical fires constitute the greatest percentage of the main causes of building fires, the critical evidence used by fire investigators to identify electrical fires is not always convincing to the general public. In this study, we scrutinized the microstructures of fire-causing copper wires and simulated the external environmental conditions required for the formation of fire-causin...

Thermodynamic, Structural and Transport Properties of Molten Copper-Thallium Alloys

A self-association model has been used to understand the concentration dependence of free energy of mixing (GM), heat of mixing (HM), entropy of mixing (SM), activity (a) and microscopic structures, such as concentration fluctuation in long wavelength limit (Scc(0)) and Warren-Cowley short range order parameter ( 1 α )for CuTl molten alloys at 1573K. A comparative study of surface tension of th...

Abdominal Vacuum Lift as an Aid to Diagnosing Abdominal Adhesions

The internal organs are designed to move freely and slide over one another during normal body movement. The abdominal organs, however, have a tendency to adhere to the abdominal cavity (peritoneum) and other abdominal organs after surgery or infection. These adhesions can cause pain, discomfort , inflammation, anxiety, depression, problems with conception, trouble eating, and decreased immune f...

Copper Recovery from Chalcopyrite Concentrate by an Indigenous Acidithiobacillus ferrooxidans in an Air-Lift Bioreactor

In this study, effects of solid concentration, temperature, and initial Fe2+ concentration on bioleaching of sulfide mineral (chalcopyrite) obtained from Sarcheshmeh Copper Mine in the region of Kerman located in the south of Iran were investigated. A mesophilic iron oxidizing bacterium, Acidithiobacillus ferrooxidans has been isolated from a typical chalcopyrite copper concentra...
