A radial-gap type superconducting synchronous machine 1 is prepared which includes a rotor 20 having, on its peripheral side, a convex magnetic pole 21 which includes, at its distal end part, bulk superconductors 30. When viewed in the direction of the rotational axis C1 of the rotor 20, the magnetic pole center side of the bulk superconductors 30 is disposed nearer to a stator 10 than the magnetic pole end side of the bulk superconductors 30. A ferromagnet 28 is disposed on the rotational axis C1 side of the bulk superconductors 30. A magnetizing apparatus 100 is disposed outside the bulk superconductors 30 in the radial direction of the rotor 20. Magnetization of the bulk superconductors 30 is performed by directing magnetic flux lines from the magnetizing apparatus 100 toward the bulk superconductors 30.

A lateral rollover risk warning device can report vehicle rollover risk in real time during traveling with no need for inputting radius of a curved path in advance. It includes a first acceleration sensor detecting an external force applied in up-down direction of a vehicle body; an angular velocity sensor detecting a rotation around vehicle axis of vehicle body; and a second acceleration sensor detecting an external force in right-left direction of vehicle body, with an arithmetic part using detection results given by first acceleration sensor and angular velocity sensor to calculate a limit index of vehicle being led to a rollover, and using detection result given by second acceleration sensor to calculate a comparative index to be compared with limit index in real time; and a reporting part using limit index and comparative index to report lateral rollover risk warning information telling the rollover risk.

Japan will likely face tough negotiations on Pacific bluefin tuna fishing this summer, when Pacific countries discuss new fishing restrictions, reports The Japan News. In August, member countries of the commission for the conservation and management of highly migratory fish stocks in the Western and Central Pacific Ocean (WCPFC) will meet to negotiate new restrictions. Observers say the negotiations will be impacted by Japan's failure to limit catches. On April 27, Japanese fishermen’s catch of immature bluefin tuna reached 4,008 metric tons, topping the annual ceiling for the first time since the restriction was introduced. “Japan topped the limit, which will affect the negotiations,” a senior official of Japan's Fisheries Agency (FA) said. Toshio Katsukawa, associate professor at Tokyo University of Marine Science and Technology said: “Japan failed to even observe the catch quota, which other countries called lenient. As a result, it’s now difficult for Japan to object to moves to strengthen restrictions." "Japan needs to review its system for having fishermen observe regulations.” Japan introduced international restrictions on fishing smaller bluefin tuna fish to increase stocks. This year, however, a series of illicit practices came to light, with some fishery operators failing to report their catches to fisheries cooperatives and unauthorized fishermen catching bluefin tuna. “We take this matter seriously,” an FA official said. “We’ll analyze the cause of the problem and take various preventive measures.” The FA plans to impose penalties for ignoring catch limits on the threatened fish from 2018 as part of efforts to seek understanding from the international community. Fishermen who ignore an order to stop tuna fishing would face up to three years of imprisonment or a fine of up to JPY 2 million ($17,740). Click here for the full story.

An object of the present invention is to provide a farmed fish or caught wild fish of a fatty state having satisfactory taste and texture by increasing the intramuscular lipid content of the farmed fish or caught wild fish for shipping the fish, and to provide a fish-rearing feed therefor. The object of the present invention is attained by providing farmed fish of a fatty state increased in intramuscular lipid content thereof by: preparing a fish-rearing feed for increasing the intramuscular lipid content of the fish, by satisfying the requirement of the amino acid necessary for fish growth with respect to the essential amino acids except lysine in a fish-rearing feed containing the essential amino acid requirements (necessary for fish growth) and adjusting the content of lysine (of the essential amino acids) in the feed to be equal to or less than the amino acid requirement (necessary for growth); and rearing fish while giving the fish-rearing feed during a period of 2 to 7 days before shipment within the rearing period (before shipment) for the farmed fish.

The rate of cesium-137 (137Cs) release to the sea from the Fukushima Dai-ichi Nuclear Power Plant for the period until September 2012 was estimated. Publicly released data on 137Cs radioactivity in seawater near the power plant by Tokyo Electric Power Company strongly suggest a continuing release of radionuclides to the sea. The plant has an artificial harbour facility, and the exchange rate of harbour water with surrounding seawater was estimated by the decrease in radioactivity immediately after an intense radioactive water release. The estimated exchange rate of water in the harbour was 0.44 d-1 during the period from 6 to 19 April. The 137Cs radioactivity in the harbour water was substantially higher than that of seawater outside and remained relatively stable after June 2011. A quasi-steady state was assumed with continuous water exchange, and the average release rate of 137Cs was estimated to be 93 GBq d-1 in summer 2011 and 8.1 GBq d-1 in summer 2012. © 2013 Author(s).
