Performance enhancement of hybrid personal cooling clothing in a hot environment: PCM cooling energy management with additional insulation.

A novel design of personal cooling clothing incorporating additional insulation sandwiched between phase change materials (PCMs) and clothing outer layer is proposed. Performance of four personal cooling systems including clothing with only PCMs, clothing with PCMs and insulation (PCM + INS), clothing with PCMs and ventilation fans (HYB), and clothing with PCMs, ventilation fans and insulation (HYB + INS) was investigated. Effect of additional insulation on clothing cooling performance in terms of human physiological and perceptual responses was also examined.

The role of 18F-FDG-PET in the local/regional evaluation of women with breast cancer.

Purpose: In women with breast cancer, knowledge of the local/regional extent of the tumor is essential for staging, treatment planning, monitoring response to therapy, and follow-up. Positron emission tomography (PET) is an important imaging test which can detect tumor at multiple sites in women with breast cancer. We compared the ability of PET to provide a comprehensive view of the local/regional extent of tumor in women with stage I, II and stage III, IV breast cancer.
