The occurrence of amendments to literature was investigated in overseas monthly journals. Four retractions and 316 errors in the literature were recorded in 102 of the 150 journals investigated. About 70% of the amendments were published within a half year of the date of the error. The word “erratum” was almost exclusively used for the expression of errors. Those results were compared with the case of the MEDLINE database.

日南海岸青島の波蝕棚表面にみられる「波状岩」あるいは「鬼の洗濯板」とよぼれる波状起伏は,潮間帯の上半部にあって,その峰部は砂岩層,谷部は主に泥岩層からなる.調査地域における両岩石の最も主要な力学的侵蝕過程は,砂岩では,日射に関連した風化による表層部の強度低下を介した波浪や風による摩耗侵蝕であり,泥岩では,表層部の乾湿破砕で分離した小岩片の波浪による除去である.これらの過程の侵蝕基準面は,それぞれの風化過程の基準面に対応して,砂岩では平均高潮位付近にあり,泥岩では平均海面の少し下方にある.また,潮間帯における侵蝕速度は,泥岩の方が砂岩よりもはるかに大きい.このため,泥岩は砂岩よりも急速にかつ低い水準まで侵蝕され,潮間帯の上半部に波状起伏が形成された.なお,波状起伏の峰は,重力侵蝕によって低下するため,その突出程度は,砂岩層に発達する節理の間隔によって制約されている.

It was generally thought that the Sumerian kingship appeared in their society which had been equal, when the Sumerian cities became to need the powerful director with the intensification of the disputes between the cities. H. Frankfort, Th. Jacobsen, S. N. Kramer, and some others generally thought like this, and concluded that the Sumerian kingship established at the Early Dynastic II.But recently some scholars has begun to think earlier than the Early Dynastic II about the appearance of the kingship. They think that the centralization and the leading minority was rather suggested in the Sumerian great enterprises as the river improvements, the irrigation, and so on, though H. Frankfort thought them useful for strengthening the unity of the community.I consider the establishment of the Sumerian kingship from the development of the temple architecture.The Sumerian temple architecture deriving from the small shrines at Eridu developed into the gigantic temples of Uruk at the late Uruk period (c. 3000 B. C.). But after this period the precincts became more extensive and to be enclosed with the walls on the one hand, the temple architecture itself was inclined to be rather small, and to be built on a high terrace, that famous ziggurat, on the other hand. Almost all the great temples at the Early Dynastic period took this style, and this suggests the separation of the grades in the Sumerian society, that is to say the privileged class to be able to use the temple on the large terrace, and the mass to be able to approach only under the ziggurat. The former intervened between the mass and the great gods, and grasped the gods' will in their hands. The most powerful man of the privileged class became their king.And so the Sumerian kingship already appeared at the late Uruk period, that is earlier than the period when H. Frankfort and some others suggested.

コマルハナバチ創設女王を誘引し,営巣させるための簡単で効率的な誘引巣箱を考案した.この誘引巣箱は,段ボールから作り,その中に木綿綿を入れた.野外に設置した15巣箱のうち53.3%が創設女王によって利用された.綿をちぎったり,綿に穴を開けたり,あるいは糖蜜や花粉を加えても営巣率に有意差はなかった.外部からの侵入者による破壊がないと,巣箱に作られた86%のコロニーが新女王を産出した.
