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.
These engineers typically fall into two categories: computer applications software engineer and computer systems software engineer. Typically a computer software engineer will work on a host of projects, including manufacturing, industry, government, and educational institutions. These professionals are often analytical and extremely detail-oriented, and generally possess a college education in computer software or software engineering.
