"But does it start in the cartilage or elsewhere in the joint? Learn how BCcampus supports open education and how you can access Pressbooks. The models would allow cardiologists and surgeons to tailor surgery for each patient based on individual anatomy, blood-flow patterns, and other factors. Before you write net force equations, it is critical to determine whether the system is accelerating in a particular direction. (b) Show graphically that the same total force is obtained independent of the order of addition ofF1 and F2. J Pers Assess. (c) Find the direction and magnitude of some other pair of vectors that add to give Ftot. You bet! 3.2 Vectors, Scalars, and Coordinate Systems, 22. Using modeling techniques he learned as an engineer, Fahmy worked out why: "It turns out that activated cells actually have clustered receptors and naive cells don't," he explains. If the object does not accelerate in a particular direction (for example, the. Close this message to accept cookies or find out how to manage your cookie settings. So I [thought], I know a little bit of immunology, I know a little bit of engineering, and I really want to talk about developing systems that can modulate antigen presentation or expand T cell populations in a specific direction. and revision questions with worked solutions.
