成型性和焊接性优良的超高抗拉强度钢的开发

概述了JFE开发并商业化生产成形性和焊接性均优良的780—1470MPa超高强度系列冷轧钢板。该系列钢板可实现汽车减重,提高碰撞安全性能。该系列钢板是JFE采用自主开发的WQ—CAL（水淬-连续退火生产线）工艺生产的,采用该工艺可以大幅降低钢中合金元素的添加量。其中新开发的1180MPa级抗拉强度钢板的伸长率得到大幅提高,是传统相同级别钢板的1．5倍,与980MPa级钢相同,且其拉伸凸缘性也与980MPa级钢相当。另外,1180MPa级钢的加工淬透性和烘烤硬化性也十分优良,完全可以替代热冲压部件。新开发系列钢可用于白车身结构件,如中梁（加强件）、保险杠、座椅结构架、座椅横挡及座椅部件（如机械锁扣）等多种用途。

Implementable L ∞ penalty-function method for semi-infinite optimization

This paper considers general non-linear semi-infinite programming problems and presents an implementable method which employs an exact L _∞ penalty function. Since the L _∞ penalty function is continuous even if the number of representative constraints changes, trust-region techniques may effectively be adopted to obtain global convergence. Numerical results are given to show the efficiency of the proposed algorithm.     

フライアッシュを用いたコンクリ一トの中性化に及ぼす暴露条件の影響

本報告はフライアッシュを使用したコンクリートの中性化についての測定結果を取りまとめたものである.シリーズⅠでは、暴露地、フライアッシュの種類、置換率における比較を行った.シリーズⅡでは、供試体の向き、設置場所、設置条件、調合条件における比較を行った.その結果、シリーズⅠにおいては、屋外暴露の場合、地域による中性化の差はあまり見られず、屋内と屋外の中性化速度係数の比は既往の実態調査結果より小さくなり、また、同一水結合材比では、フライアッシュの種類による中性化の差は認められなかった.シリーズⅡでは、中性化速度係数は屋外に置いて屋根なしより屋根ありのほうが大きい値を示し、また、建物の南側より北側のほうが小さい値となった.     

Near Infrared Spectroscopic Measurement of Protein Content in Oil/Water Emulsions

The regression coefficient (slope) of the calibration for determination of the protein content decreased as oil content increased. A corrected equation for the effect of oil was derived using optical intensities at 2170 nm (protein) and 2306 nm (oil). The accuracy of the corrected calibration was tested against separate data sets with each oil content. Standard errors of the corrected calibration were comparable to the standared regression equation over a wide range of oil content, suggesting that this corrected calibration is useful for determination of the protein content in oil/water emulsions.     

Formation of Transparent Gels of Sesame 13S Globulin: Effects of Fatty Acid Salts

The physicochemical properties of sesame 13S globulin gels containing fatty acid salts (FAS) were investigated. The softness, water-holding ability and transparency of the gels markedly increased in the presence of sodium oleate (NaCl_18:1) or sodium linoleate (NaC_18:2) at a 75 molar ratio to a molecule of the 13S globulin. The effect was not observed by the addition of sodium caprylate (NaC_8:0). Scanning electron microscopy showed that a very fine network structure was formed in the gel with 75 molar ratio of NaC_18:2. The addition of a suitable amount of FAS having a moderate length and an unsaturated carbon chain could improve the water-holding ability and transparency of the 13S globulin gel.     

Limonoid glucosides in Orange Molasses

The concentrations of limonoid glucosides in orange molasses, a byproduct of citrus juice processing, were measured. The 17-β-D-gluco-pyranoside derivatives (glucosides) of limonin, nomilin, nomilinic acid and obacunone were present and quantified. Orange molasses contained an average of 568 ppm of total limonoid glucosides at 11.8°Brix. Orange molasses (3.8L) contained up to 12.5g of total limonoid glucosides. The molasses could be used as a source for commercial isolation of citrus limonoid glucosides.     

KINETICS OF LYCOPENE DEGRADATION IN TOMATO PUREE BY HEAT AND LIGHT IRRADIATION

Lycopene as a natural antioxidant may provide protection against a broad range of epithelial cancers. Tomatoes and tomato‐based food products are a major source of lycopene compounds. Thermal processing is the main procedure in tomato puree production. Heat and light induces lycopene oxidation and isomerization of the all‐trans form to the cis form. The level of cis‐isomers increases as treatment time increases but only for a short period during the beginning of the treatment. The major effect of thermal processing was a significant decrease in the total lycopene content. Lycopene is relatively stable if heated at temperatures below 100C, but the duration of heating must be taken into consideration. The kinetics of lycopene degradation was analyzed. A shorter period of time of heating and less light irradiation in processing and storage would reduce lycopene degradation to a great extent.
