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.
There are several popular fields that computer hardware engineers work in and the salary of the computer hardware engineer may vary according to the specific field. The median annual salary for a computer hardware engineer who works in computer and information technology services is $77,000. The annual salary for a computer hardware engineer is slightly higher at about $83,000 if he or she works in the computer and office equipment field.
