Involvement of the lung causes shortness of breath or fatigue during physical activity. Many patients with scleroderma become less physically active because of musculoskeletal complaints or the fatiguing nature of the illness. Hence many will not be physically active enough to actually develop shortness of breath.
Computer hardware engineers research, design, develop, and test computer systems and components such as processors, circuit boards, memory devices, networks, and routers. These engineers discover new directions in computer hardware, which generate rapid advances in computer technology.
Career Definition. The rapid improvements seen in computer technology are largely due to the work of computer hardware engineers. The responsibilities of a computer hardware engineer may include designing and testing new keyboards, computer chips or printers or overseeing the manufacturing of these types of items. A computer hardware engineer usually works indoors in a typical office or laboratory and has a traditional 40-hour work week.
