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.
Computer engineers usually can be found fulfilling their duties in high-tech manufacturing firms or research laboratories that build various types of computer models. Computer engineers have the option of moving into hardware or software positions as well as an equal blend of the two.
