We report that a nest of mud-dauber wasp, Sceliphron sp., was found in the Yagibara Shell Mound of Jomon cultural age in Chiba Prefecture, Honshu, Japan. This is the first record to be found nest of Aculeata from shell mounds. Though all Sceliphron species recorded from Honshu, Japan have been considered to be invasive insects, at least one species is considered to be native.

Several works have been reported of the concentration of oleyl oleate from sperm oil. But the oleate oleyl concentrated from sperm oil is so unstable due to the presence of highly unsaturated components that the application of oleyl oleate is limited. It is therefore, necessary to reduce these highly unsaturated components in the oleyl oleate concentrate. The authors attempted to decrease the amounts of polyunsaturated components in sperm body oil by two procedures. The one was to thermally polymerize sperm oil in the presence of active earth, and the other was to hydrogenate the oil selectively with Cu-Cr catalyst under atmospheric pressure. The oleyl oleate was concentrated from thus treated sperm body oils and untreated oil through molecular distillation and fractional crystallization. A.O.M. stabilities of these oleyl oleate concentrates were determined according to the A.O.C.S. analytical method. The oleyl oleate concentrate obtained from thermally polymerized sperm body oil was most stable, while the oleyl oleate from untreated sperm oil was unstable most.

シロナガスクジラのひげよりとれた脂質について成分検索の結果, 約20%のステリンを抽出することができステリンの大部分がコレステリンであることを確認した。なお, 組成脂肪酸は主としてモノエテノイド酸からなるように思われる。

Poly [(sodium acrylate) -<I>co</I>- (vinyl alcohol)] P (A-VA), poly [(sodium acrylate) -<I>co</I>- (methyl vinyl ether)] P (A-MVE), polyL (sodium 2-hydroxyacrylate) -<I>co</I>- (sodium acrylate) P (HA-A), poly [(disodium maleate) -<I>alt</I>- (vinyl alcohol) P (Ma-VA), poly (disodium fumarate) -<I>alt</I>- (vinyl alcohol)] P (F-VA) were prepared, and their building performances in detergents were examined. Their sequestering power for Ca<SUP>2+</SUP> and dispersing power MnO<SUB>2</SUB> were determined and compared with the corresponding properties of sodium tripolyphosphate (STPP) and disodium 3-oxapentandioate (ODA). The biodegradability of the oligomers was also studied under aerobic conditions.<BR>These oligomers showed better detergency building performances than those of ODA, and some of them were superior to those of STPP. Oligomeric P (A-VA) prepared by UV polymerization showed the best building performances in detergent systems and biodegradability tested in this report. The introduction of hydroxyl groups and ether groups to poly (sodium acrylate) promoted their detergency power and biodegradability.
