Concentration Levels

LC/MS analysis with improved SPE preparation was applied to determine trace amounts of LAS in river waters. By using this procedure, the distribution of LAS was investigated and compared with the previous concentration level measured by HPLC in the Akashi River flowing through urbanized coastal areas in Hyogo Prefecture, western Japan. Detected LAS were in the range of 0.6-11 μg/L and considerably lower than those in 1985. This indicated that LAS concentration levels reduced to 1/10 and below during the past 18 years. From the model analysis, major factors contributing to the reduction of their concentrations were estimated to be the sewerage development and the decrease of consumption of anionic surfactants. Statistical analysis of MBAS monitoring data suggested that over 90% of sewerage diffusion rate was needed in order to reduce LAS to the concentration level of the order of 10 μg/L in river waters.

I would like to express my sincere appreciation for the honor of receiving this prestigious award. The award has been presented to me for the “Special Issue on NIED Frontier Researches on Science and Technology for Disaster Risk Reduction and Resilience 2017” of JDR Vol.12 No.5, for which I was the guest editor. I heard that this special issue has been the most downloaded over the past three years. NIED, to which I belong, is an institute that deals with natural disasters comprehensively. Since 2016, we have been working to become a “core organization for innovation in disaster resilience science and technology” as a new seven-year plan. Japan is a country prone to disasters, with many large-scale natural disasters occurring every year. Recent examples would be the 2016 Kumamoto Earthquake, 2017 Nasu Avalanche, Northern-Kyushu Heavy Rain, 2018 Eruption of Mt. Kusatsu-Shirane, Western-Japan Heavy Rain, Hokkaido Eastern Iburi Earthquake, and 2019 Typhoon #19. We should collect “intelligence” related to natural disasters in multiple fields to reduce our disaster risk and improve our resilience. The Special Issue is a compilation of research results from individual fields. I am elated that the first special issue of NIED has gained such attention. NIED will continue to conduct research across multiple fields. We hope that NIED’s activities will lead to collaboration with many people and that the integration of intelligence will improve disaster resilience in Japan and all over the world.

The Continuum

A continuum survey of the galactic-centre region has been carried out at Parkes at 20 cm wavelength over the areal11= 355° to 5°,b11= -3° to +3° (Kerr and Sinclair 1966, 1967). This is a larger region than has been covered in such surveys in the past. The observations were done as declination scans.

Origin Of The Moon

During the last 10 years, the writer has presented evidence indicating that the Moon was captured by the Earth and that the large collisions with its surface occurred within a surprisingly short period of time. These observations have been a continuous preoccupation during the past years and some explanation that seemed physically possible and reasonably probable has been sought.

History Of

It is generally accepted that history is an element of culture and the historian a member of society, thus, in Croce's aphorism, that the only true history is contemporary history. It follows from this that when there occur great changes in the contemporary scene, there must also be great changes in historiography, that the vision not merely of the present but also of the past must change.

Fast Flow

It is perhaps one of the most important characteristics of the past decade in astronomy that the evolution of some major classes of astronomical objects has become accessible to detailed research. The theory of the evolution of individual stars has developed into a substantial body of quantitative investigations. The evolution of galaxies, particularly of our own, has clearly become a subject for serious research. Even the history of the solar system, this close-by intriguing puzzle, may soon make the transition from being a subject of speculation to being a subject of detailed study in view of the fast flow of new data obtained with new techniques, including space-craft.

During the past several years, a systematic search for novae in the Magellanic Clouds has been carried out at Cerro Tololo Inter-American Observatory. The Curtis Schmidt telescope, on loan to CTIO from the University of Michigan is used to obtain plates every two weeks during the observing season. An objective prism is used on the telescope. This provides additional low-dispersion spectroscopic information when a nova is discovered. The plates cover an area of 5°x5°. One plate is sufficient to cover the Small Magellanic Cloud and four are taken of the Large Magellanic Cloud with an overlap so that the central bar is included on each plate. The methods used in the search have been described by Graham and Araya (1971). In the CTIO survey, 8 novae have been discovered in the Large Cloud but none in the Small Cloud. The survey was not carried out in 1974 or 1976. During 1974, one nova was discovered in the Small Cloud by MacConnell and Sanduleak (1974).

Definition Of

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).
