    Notes: Summary We studied immunohistochemical stains for TPA and CA125 in patients with benign and malignant gynecologic diseases. The results were as follows: (1) CA125 was not found in ovarian mucinous cystadenocarcinoma but was demonstrated immunohistochemically in 82% of ovarian serous cystadenocarcinomas and 83% of Krukenberg's tumors. (2) TPA was demonstrated in 65% of ovarian serous and 75% of ovarian mucinous cystadenocarcinomas, and in 58% of endometrial carcinomas. (3) TPA was found in all trophoblastic tumors examined, while CA125 was found in none. Eighty-three percent of patients with trophoblastic diseases had raised serum TPA levels. (4) When serum CA125 levels were raised, CA125 was demonstrated immunohistochemically in 71% of patients with ovarian serous cystadenocarcinomas, 67% of patients with Krukenberg's tumors and 100% of patients with tubal carcinomas. (5) Despite elevated serum levels, CA125 and TPA were not identified by immunohistochemistry in 64% cases of benign ovarian disease and in 80% of patients with uterine myomata. (6) It would seem that CA125 was more easily released from tumor cells than TPA.

    Notes: Summary We studied the pretreatment serum levels of 6 tumor markers in gynecological patients with and without malignant disease. The tumor markers were carcinoembryonic antigen (CEA), tissue polypeptide antigen (TPA), ferritin, Schwangerschaftsprotein 1 (SP1), Schwangerschaftsprotein 3 (SP3) and cancer antigen 125 (CA125). The results were as follows: (1) Serum CA125 and TPA levels were raised in 81% and 57% of patients with ovarian serous cystadenocarcinoma: CEA and SP3, in 52% and 43% respectively of patients with ovarian mucinous cystadenocarcinoma; CA125, TPA and SP3, in 76%, 48% and 48% respectively of patients with other ovarian malignancies; and TPA and SP3, in 56% and 40% respectively of patients with endometrial carcinoma. (2) Serum levels of TPA, ferritin and CA125 were more often raised with advancing stages of malignant disease. (3) Serum TPA levels were elevated in 55% of patients with stage I endometrial carcinoma, and serum SP3 levels were elevated in 35% of patients with a stage I malignant ovarian neoplasm and in 45% of patients with endometrial carcinoma. (4) One of the 6 tumor markers showed a raised level in 84% of patients with gynecologic malignancy as against 56% in those with benign gynecologic diseases.

    Conversion of Auger sensitivities at one primary excitation energy to those at anotherPaper presented at the Quantitative Surface Analysis (QSA-5) Conference, London, 15-18 November 1988. (1989)

    Notes: In Auger electron spectroscopy, the relative sensitivities of elements, which are widely used in quantitative analysis, are primarily obtained by measurement. Nevertheless, it is very tedious to collect all relative elemental sensitivity factors for different primary electron beam energies. In view of this, we have examined methods of deriving the relative sensitivity factor for an arbitrary electron beam energy from one experimental value determined at a set energy. For this calculation, we have to consider the contributions of the ionization cross-section and the electron backscattering factor. Several formulas for the ionization cross-section and the backscattering correction factor have been reported. We have performed experiments to examine their correction accuracy. It was found that when Gryziński's formula is used as the ionization cross-section and Love-Scott's formula as the backscattering correction factor, the difference between calculated sensitivity values and measured values was found to be 〈15% for excitation energies of 〈20 keV.

    Bending properties of compression molded three-layer long fiber polypropylene composites (1994)

    Notes: The results of studies on bending properties of three-layer long fiber polypropylene composites are presented. Thirteen samples with glass fibers of various lengths (i.e., 13, 25, 50 mm and continuous fiber length) in the laminates were prepared by stamping. Bending properties of shorter lengths exhibited a large scatter. On substitution of the middle layer with a continuous glass fiber the scatter was reduced. These results have been explained on the basis of flow models and X-ray shadowgraphs, which showed that both slippage flow and orientation of the glass fiber during stamping are the major phenomena responsible for the scatter.

    Flow behavior of stampable sheet with a rib part (1994)

    Notes: The effect of die design on the flow characteristics of compression molded three-layer long glass fiber reinforced polypropylene composite, known as “stampable sheet,” was investigated. The flow behavior of each layer was observed by optical and soft X-ray photographs. The fiber flow length into the rib part was measured by an image processing system. The results showed that during compression resin exudation occurred and that this depended on the die's rib width. Thus, the larger the rib width, the lower the amount of resin exuded. Resin exudation was found to occur earlier in a die with zero fillet radius. The fiber flow length into the rib part was enhanced by using a die with a large fillet radius. The results were confirmed by a short-shot molding process. In this process, the stamping operation was stopped short of making a complete part.A finite element method was used to study the flow process. The results agree with the experimental results confirmed by short-shot molding.

    Statistical mechanical theory for liquid-crystalline polymer solutions (1994)

    Notes: A statistical mechanical theory is presented for liquid-crystalline polymer solutions, where the liquid-crystalline polymer is regarded as a wormlike spherocylinder interacting by the hard-core repulsion and a soft (attractive or electrostatic) interaction with other spherocylinders. The theory is based on the following two assumptions: (1) the intramolecular excluded volume effect is not effective and (2) the interaction between pair of spherocylinders can be treated by the “single contact approximation”. These assumptions are relevant to a polymer with a stiff backbone and not very long contour length. The theory is used to predict thermodynamic and spatial properties of isotropic solutions and also isotropic-liquid crystal phase equilibrium behavior. The predicted solution properties and phase behavior are favorably compared with experimental results for some selected stiff-chain liquid-crystalline polymers.
