Most of requirements for hemodialysis hollow fiber membranes depend on their micro pore structure and distribution. Therefore, not only the averaged pore radius but also the pore radius distribution should be noted in the optimal design of hollow fiber hemodialysis membranes. Herein some advantageous characteristics of newly developed cellulose hemodialysis membrane, pore radius distribution pattern of which may be so called “symmetricall gradient structure”, are presented with those of the conventional and well known homogeneous, gradient, and reverse gradient structure membranes.

The seasonal and horizontal distributions of <i>Skeletonema costatum</i> (GREV.) CLEVE were observed five times in the surface water of Yatsushiro Sea, Kumamoto and Kagoshima Prefectures, from October 1983 to November 1984. Numerically, <i>S. costatum</i> was by far the most important phytoplankton, with two maxima in February and in August. In terms of cell number, this species amounts to more than 50% of the total phytoplankton whenever the community density is more than 10<sup>5</sup> cells/<i>l</i>. The first maximum in February seems to be triggered by the release from zooplankton grazing pressure, since the high cell density of <i>S. costatum</i> and the high concentration of DIP were observed widely in Yatsushiro Sea. The second maximum in August seems to be attributed to the nutrients supplied through R. Kuma, since a marked horizontal gradient of <i>S. costatum</i> strongly related to those of salinity and DIP.

アイントーベンの時代以来,心室筋の興奮ベクトルが心電計の陽極端子の方向に向くと心電計は+に振れるとの理論が長らく継承されてきた.この理論はR波および平均電気軸の説明に通用しても,STセグメント,T波形成の理論づけには役立たない.本稿で提唱する心電図の統一理論は心内膜側心室筋活動電位より心外膜側心室筋活動電位を引き算することにより体表心電図が発生するというもので,心電計の差動増幅回路の機能を素直に文章に表現しただけのものである.この考え方で活動電位の変化をシミュレートすると,病的心電図の再現はもとより,致死的状況で心外膜側心筋にまで興奮が及ばない墓石様心電図波形まで説明することができる.

This experiment was conducted to evaluate the effect of the amount of irrigation water on growth and grain yield of grain sorghum during drought stress period and to make efficient use of irrigation water under four treatments : 0, 1, 2 and 3 irrigations per week. Twenty millimeters of water was applied at each irrigation time. Irrigation water was applied from July 12 to Augllst 2, when grain sorghum was heading time through milk stage. Leaf water potentials measured by pressure chamber (Daiki Rika K.K.) were affected by the quantity of irrigation water and lowered by less amount of irrigation water. The recovery of leaf water potential by irrigation was 2 to 3 bars and the difference of leaf water potential between well irrigated treatment (3 irrigations per week) and others was enlarged when drought stress was accelerated. Two irrigation treatment never became lower than - 19 bars which is a critical point of grain sorghum when stomata close. Leaf diffusive resistance measured by porometer (Lambda Instruments Corp.) was high in no and one irrigation treatments. However, it was low in two and three irrigation treatments and no difference was recognized between them. Top growth of grain sorghum was slowered and stopped by drought stress and its recovery after drought was small. Stressed top growth was mainly due to slow development of grain head and decay of lower leaves. Grain yields decreased as the amount of irrigation water decreased, but no statistical difference was recognized between well irrigated and two irrigation treatments. Reduced grain yields were attributed to low 1,000 grain weight. From the results of grain yield and difference between evapotranspirations and the amounts of irrigation water during drought stress period, drought damage will be reduced by irrigation of about 40 millimeters of water a week.

田辺湾の潮間帯の砂泥域でコアマモ群落の底質環境とベントス群集の関係を明らかにした。底質環境では,コアマモ群落の AVS が裸地よりも高く,群落内での嫌気分解の卓越が示唆された。コアマモ群落のベントス群集は,裸地との類似度が高いものの,種数や個体数,現存量が高く,コアマモ群落の生育場所に応じて多様であった。また,優占種の上位10種のうち,7~8 種が埋在性の堆積物食者および懸濁物食者であった。以上のことから,コアマモ群落は埋在性種を中心としたベントス群集の好適な生息場所になっていると考えられ,コアマモ群落は多様な動物群集を支える沿岸生態系の基盤種として重要であり,コアマモ自身の保全が重要な意義を持つと考えられた。また,コアマモ群落は生息場所に応じた多様なベントス類に好適な生息・餌料環境を提供していると考えられたことから,保全すべき沿岸生態系としてのコアマモ群落の意義は極めて高いことが示唆された。

The authors have developed a new type rolling mill named the satellite mill. The mill comprises one large diameter roll (central roll) and five smaller diameter rolls (satellite rolls) arranged along a circumference of the central roll. Material is passed continuously through the five gaps between the central roll and the satellite rolls and deformed into a profiled cross section. Since all rolls are driven at the same roll speed, longitudinal compressive stress is produced between stands during rolling. The elongation is greatly suppressed. The mill has been applied to the production of round-edged flat wires and two kinds of T-shaped profiled wires from round circular wires. The obtained rolling characteristics and product properties are compared with those by a conventional rolling method. It is shown that the transverse metal flow is enhanced and the filling ability to the roll groove is excellent in satellite-mill rolling. The effect is more apparent in rolling of T-shaped wire having thinner ribs. It is supposed that the satellite mill is favorable for profiled wire production.
