Development and Validation of a Simulator based on a First-Principle Flotation Model
… bubble is negative, as was first suggested by Laskowski and Kitchener (1969). These provisions allow for the flotation model to incorporate various chemistry parameters such as zeta-potentials, contact angles, surface tension in addition to the physical and hydrodynamic parameters such as …

The synergistic interaction between dithiophosphate and frothers at the air-water and mineral-water interface
… in literature (Leja & Schulman, 1954; Lekki & Laskowski, 1971; Dai, Bradshaw & Harris, 2001; Jordaan, 2018). These interactions have been shown to improve sulphide mineral recovery. Dithiophosphate (DTP) is a collector in sulphide mineral flotation which has been shown to synergistically …

Testing models of the adaptive evolution of consistent individual differences in behavior using sticklebacks
Traditionally considered one of the most plastic traits an individual could exhibit, there is now mounting evidence that individuals within the same population often differ in their behavior and that these differences are consistent over time and/or across context. This does not necessarily imply …

Natural and Exogenous Genome Editing In Wiskott-Aldrich Syndrome Patient Cells
<p>Wiskott-Aldrich syndrome (WAS) is an X-linked primary immunodeficiency disease characterized by thrombocytopenia, recurrent infections and increased autoimmunity. This disease is caused by mutations in the WAS gene (<em>WAS</em>) which encodes for the WAS protein (WASp), exclusively expressed in …

Using a product engineering process to manage an introductory mechanical engineering program
"Discover Mechanical Engineering" (DME) is a student-run Freshman Pre-Orientation Program at the Massachusetts Institute of Technology which, in the time since its inception in 2002, has developed into a popular, professional, and well-organized pre-orientation program MIT. Yet despite its success, …
