Seventy percent of the lower boundary of the atmosphere is contact with sea surface where heat and water vapor are supplied to the atmosphere. On the other hand, the wind stress at the sea surface induces the wind-driven circulation inside of the oceans which transports and mixes heat inside of the oceans. The variation of sea surface temperature are caused by both the atmospheric and oceanic processes. These features imply that the atmosphere and the oceans are a coupled system which is the basis of the Earth environment. This overview shows how the oceans give various influences to the atmospheric processes.

The Sada River is a canal, 8.3km in length, built about 200 years ago which connects the Sea of Japan with Lake Shinji directly. Observation was carried out using a automatic water quality and current meter to investigate the movement of invading sea water through the River. The results indicated that, though the movement of the river water is basically controlled by the tidal fluctuation of the Sea of Japan, the sea water can scarcely reach Lake Shiniji because of the long distance of the canal and small tide range of the sea. The acceleration of sea water upstreaming mainly depends on the pushing effect of a strong west wind and sea water swelling due to the low atmospheric pressure in the Sea of Japan. The moment the upstreaming of oxygen-rich sea water into the lake depends on the atmospheric conditions which is inconsistent. If it is possible to control artificially the inflow of sea water into the lake, it will greatly enhance the self-purification of the lake water and bottom sediment which in turn will increase the benthic biological activity.

Tofu is a popular and traditional Japanese food. It is formed by the formation of heat-induced gels of soybean proteins, leading to determine its texture. Salts are used as coagulants on an industrial scale for the preparation of tofu and strongly affect the gel formation of soybean proteins. This article focuses on effects of salts on physical properties and gel structures of tofu. We explain: 1) relationship between physical properties and gel structures of commercial tofu, 2) effect of different coagulants on physical properties and gel structures of tofu, 3) effect of sodium chloride on the gel formation of soybean protein isolate, 4) effect of sodium chloride on physical properties and gel structures of tofu.

Point defects in crystals consist of holes, interstitial atoms, and impurities. These point defects are important for physical and chemical properties of the crystals. In particular, impurities and electrons trapped in holes are responsible for optical properties of the crystals. In jewelry such as ruby and sapphire, d-d transition of impurity transition-metal atoms is the origin of its sparkling color. Similarly to the colors of ruby and sapphire, a crystal such as NaCl and MgO can be colored. The color of such crystals is due to electronic transitions of color centers, which consist of electrons trapped in hole sites. Interactions between photons and electrons in the color centers are explained from the basic theory of the quantum mechanics. The electronic structures of the F and U centers in NaCl and of various F centers in MgO are discussed from results obtained by recent molecular orbital calculations.

“Saltdamage” in Crop is classified into three,(1) salt water damage,(2) salt wind damage, and (3) salt soil damage, according to the difference in a generating mechanism.This paper, it introduces about the characteristics of the salt wind damage by the typhoon 0415. Typhoon 0415 (T0415, MEGI) passed through the Sea of Japan coast of Hokuriku and Tohoku Districts on August 19-20, 2004. Agust of wind stronger than 30m/s was recorded in the coastal region, and a gust of wind at 38.3m/s, 39.6m/s, and 41.1m/s was observed in Aikawa, Sakata, and Akita, respectively. However, there was little rainfall before and after the passage of the typhoon. Consequently, the adhering salt entered the rice plant, and salty wind damage occurred by drying up the cells. Near the seashore, 2.7-3.2mg salt had adhered to the panicle, and the amount of salt adhesion per panicle (mg/panicle) negatively correlated with the distance from the seashore. The total amount of the agricultural damage by T0415 was 18 billion yen, 10,200million yen, and 7,200million yen in Ahta Prefecture, Yamagata Prefecture, and Niigata Prefecture, respectively. The amount of rice damage occupied three fourths of the whole crop The ratio to normal year of the rice yield fell greatly in Akita Prefecture (Kisakatacho, southern prefecture coast area) and Niigata Prefecture (Sadocity). In the Niigata Sado area and the Akita Honjo area, the quality of rice deteriorated remarkably.

A braid adsorbent having the functional group of amidoxime is a promising material for the recovery of uranium (U) dissolved in the seawater. This long braid adsorbent was made by polyethylene multi-fibers in which amidoxime groups were introduced by radiation-induced graft polymerization and a subsequent chemical treatment. The braid adsorbent obtained was moored at the offing of Okinawa Island. The average U adsorption of the adsorbent became 1.5g-U/kgadsorbent for 30d soaking.The mooring system for braid adsorbent has possibility which reduced the cost for the recovery of U from seawater. Annual product of 1,200 tons of U needs 134km2of mooring area. In addition, there is 6,000 km2 and more of suitable sea area for the collection of the U in the regions from Okinawa Islands to Tosa Bay in Japan.
