    Notes: Abstract A combination of quadrantectomy, axillary dissection, and radiotherapy (QUART) is the regimen most favored by Japanese surgeons among a variety of breast conserving therapies currently available against breast cancer. Unfortunately, extensive resections such as quadrantectomy often give poor local cosmetic results in patients with small breasts. With the aim of improving the cosmetic aspect after an extensive resection, immediate transposition of the latissimus dorsi muscle (LDM) was carried out in breast conserving surgery. To date, twenty-one patients have been entered in this study. Post-quadrantectomy breast deformity was not corrected in six patients including one with bilateral breast cancers, but was corrected by transposition of a part of LDM in 14 other patients. In the last patient, who also had bilateral breast cancers, the right breast was treated by QUART and the left breast by subcutaneous mastectomy followed by transposition of LDM. The cosmetic outcome for these patients was assessed both subjectively and objectively; the objective assessment used a Moire topography camera. The postoperative appearance and topography revealed a satisfactory symmetry of breasts in the transposed patients, especially those with small breasts, when compared with non-transposed patients. It may be concluded that the transposition of LDM is useful in preventing breast deformity following an extensive resection in breast conserving surgery.

    Spectroscopic study on the crystal growth in gas evaporation: emission and absorption spectra from Cu smoke (1991)

    Notes: Abstract Optical emission and absorption spectra from a growth zone in Cu smoke were measured by using a quartz prism spectrograph and a single-grating spectrophotometer. Atomic lines of Cu, band systems of Cu2 were observed. Two new band systems with 0–0 band heads at 252.88 and 238.79 nm were found. The continuous spectra due to Rayleigh scattering by fine particles were also observed. Variations of density of various species as a function of vertical position were revealed.

    Information theory of optimization in chromatography: Optimum peak separation and dependency on peak area (1991)
    Springer
    Chromatographia 32 (1991), S. 233-237

    ISSN: 1612-1112

    Notes: Summary If a peak (j=2) moves along the time axis of a chromatogram with no change in the position τ1 of the other peak (j=1) or in areas A1 and A2, the optimum separation, Řs, is defined as the resolution Rs which provides the maximum information, called FUMI, among all possible positions τ2 of the peak (τ2≥τ1). This paper demonstrates that optimum separation, Řs, of chromatographic peaks critically depends on the peak areas. As the area ratio A2/A1 of overlapped peaks increases, greater separation (higher resolution Rs) is needed to obtain maximum information. The quantitative relationship between Řs and A2/A1 is derived by computer simulation.
