Patellar (Kneecap) Fractures. A patellar fracture is a break in the patella, or kneecap, the small bone that sits at the front of your knee. Because the patella acts as a shield for your knee joint, it is vulnerable to fracture if you fall directly onto your knee or hit it against the dashboard in a vehicle collision.
Quality management system. A quality management system (QMS) is a collection of business processes focused on consistently meeting customer requirements and enhancing their satisfaction. It is aligned with an organization's purpose and strategic direction (ISO9001:2015).
Quantum mechanics (QM) is the part of physics that tells us how the things that make up atoms work. QM also tells us how electromagnetic waves like light work. QM is a mathematical framework (rules written in math) for much of modern physics and chemistry. Quantum mechanics helps us make sense of the smallest things in nature like protons, neutrons and electrons.
