Call your doctor immediately if you have: 1  Blood in your diarrhea or black, tarry stools. 2  A fever that is high (above 101 F) or that lasts more than 24 hours. 3  Diarrhea lasting longer than 2 days.  Nausea or throwing up that prevents you from drinking liquids to replace lost 1  fluids. Severe pain in your abdomen or rectum.
The discipline of engineering is extremely broad, and encompasses a range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied science, technology and types of application.
Electrical engineering is the most math heavy of the engineering disciplines. You rely heavily on differential equations when dealing with advanced circuit analysis and electromagnetism is basically a physics and math course. In a close second is mechanical engineering, which uses dynamics a lot. Chemical engineering is in last probably. Differential equations are used a lot, but that is true of all the engineering disciplines. Industrial engineering often has a lot of economics built in, which of course uses mathematics. This is all very subjective though, but I think it is a good characterization.
