The absolute fluorescent quantum efficiencies of NBS phosphor standard samples which were excited by a 254nm radiation were measured by a polychromator. The polychromator was calibrated by a conical cavity thermal radiation detector, which used polyvinylidene fluoride (PVDF) films, coated inside with gold black absorber. The effective spectral absorptance of the derector was constant within 0.3% over a wavelength region of 200〜600nm. Reproducibility of the absolute fluorescent quantum efficiency was within ±0.02. The relative values of fluorescent quantum emitted per 254nm incident radiation quantum agreed with the NBS data within 3%. The fluorescent quantum efficiency of NBS phosphor standard samples (NBS 1027) was 0.81.

1982年John Brough によって,あるガンダーラ仏像の台座に刻された碑文が阿弥陀仏と観音菩薩に言及したものであると報告され,注目を集めた。さらに,John Brough はこの碑文の年代を紀元後2 世紀と推定した。その後,この碑文の解釈を巡って議論がなされたが,未だ最終的な解決が出たわけではない。一方,パキスタン北部で発見された碑文群は,北西インドの仏教信仰の実情を研究する上で大きな意味を持ち,本稿で論じる当該のカローシュティー碑文を考察する上でも,示唆に富むものである。本稿では,これらのパキスタン北部碑文資料を参照しながら,当該碑文を再検討しガンダーラ地域における阿弥陀信仰を論じる。

Background: The prion protein (PrP) has been reported to serve as a surface maker for isolation of cardiomyogenic progenitors from murine embryonic stem (ES) cells. Although PrP-positive cells exhibited automaticity, their electrophysiological characteristics remain unresolved. The aim of the present study was therefore to investigate the electrophysiological properties of PrP-positive cells in comparison with those of HCN4p-or Nkx2.5-positive cells. Methods and Results: Differentiation of AB1, HCN5p-EGFP and hcgp7 ES cells into cardiac progenitors was induced by embryoid body (EB) formation. EBs were dissociated and cells expressing PrP, HCN4-EGFP and/or Nkx2.5-GFP were collected via flow cytometry. Sorted cells were subjected to reverse transcriptase-polymerase chain reaction, immunostaining and patch-clamp experiments. PrP-positive cells expressed mRNA of undifferentiation markers, first and second heart field markers, and cardiac-specific genes and ion channels, indicating their commitment to cardiomyogenic progenitors. PrP-positive cells with automaticity showed positive and negative chronotropic responses to isoproterenol and carbamylcholine, respectively. Hyperpolarization-activated cation current (If) was barely detectable, whereas Na+ and L-type Ca2+ channel currents were frequently observed. Their spontaneous activity was slowed by inhibition of sarcoplasmic reticulum Ca2+ uptake and release but not by blocking If. The maximum diastolic potential of their spontaneous firings was more depolarized than that of Nkx2.5-GFP-positive cells. Conclusions: PrP-positive cells contained cardiac progenitors that separated from the lineage of sinoatrial node cells. PrP can be used as a marker to enrich nascent cardiac progenitors.

Powders of LiNbO_3 were synthesized by novel peroxide route based on reaction of niobium peroxide and lithium hydroxide. A pH of 11 was found to provide optimum condition for the formation of peroxo niobium precursor complex [Nb(O_2)_4]^<3->. The replacement of peroxide ligand was favored by increasing the reaction temperature above ambient. This method demonstrated its efficacy in obtaining pure and homogeneous crystalline LiNbO_3 powders at reduced temperature (400℃) without involvement of organic substance. The crystalline phase was characterized via powder X-ray diffraction and Infrared, Raman spectroscopy. SEM micrographs enabled in detecting the formation of inverse opal of LiNbO_3 . For comparison LiNbO_3 was also prepared by amorphous complex method independently and characterized. The peroxide approach presented here gives an alternative for the preparation of multi component oxides free from organics and chlorides.

Dealing with California water problems, Engelbert has described as follows; "Obviously, regions with rapid population growth will face urban water shortages sooner than less rapidly growing regions if current pricing and allocation practices continued." So, "Control of urban development and urban water conservation are identified as major factors intimately related to future urban water supply management" (Engelbert, 1982). This description is very suggestive for the people who are concerning the water problems regarding resource saving and management. In those areas where the expansion of residential areas are in process, it can be assumed that the reasonable water saving will be actualized through a system in which the marginal cost of supplying urban water is imposed on those consumers that are the very new dwellers in newly develped urban areas by whom the water supply costs are raised highly. The Salt Lake City Dapartment of Public Utilities is responsible for water service to the corporate limits of the city and to a large portion of the unincorporated southeast section of Salt Lake County. And those both areas had formed the Metropolitan Water District and sponsored the Provo River Project to develop dependable water resources by construction Deer Creek Reservoir and Salt Lake Aqueduct. Today it provides water to a population of 375,000 people approximately including workers and visitors from outside the city limits during the day, and delivered water annually is estimated 140,000 acre-feet. West Valley City which is one of the satellite towns of the Salt Lake City is located on the western side of the Jordan River, where is on the eastern end of the slopes extending from the Oquirrh Mountains. It occupies the southwestern suburban corner of the Salt Lake City and it can be reached after half an hour drive from the downtown area of the Salt Lake City. West Valley City was incorporated as the city in 1980 with population of 72,378 and 21,270 occupied housing units. Also this district is situated at the northern terminal of the several canals that are diverted on the Jordan Narrows and conveying irrigetion water from south to north following eastern slopes perimeter of the Oquirrh Mountains. Until 1960s, the predominant land use of this area is wheat cropping or pasturing, irrigated or non-irrigated respectively. Rapid population growth and land use conversion from farmlands to residential purposes have arisen and continued during and after 1960's due to Salt Lake City's urban growth and areal expansion of the peoples journey to work. Dwellers of the West Valley City could obtain adequate water for their communities from the small local wells in their early days. But soonly inadequacy of the local sources was felt. Immediately after the Provo River Project implemented, from the 'Terminal Reservoir' on the East Bench, pipes called 'Kearns Supply Line' were installed to bring treated water to West Valley area along 33th South Street crossing over Jordan River. This is their step to stabilize ample water supply. But this water is not secured longer because it is the short term surplus water of the Provo River Project, and Salt Lake City will exercise full share of its own water right after 1990. Then, as the second step, they have to go to tap C. U. P. (Central Utah Project) water via Jordan Valley Water Purification Plant and after 1988 the new supply system has gone into operation. Although there are very closely urban functional connection between Salt Lake City and West Valley City, each of them have their own water supply systems independently. Salt Lake City had participated into the Provo River Project and obtained the water right on Deer Creek Reservoir water. During 1981-85, under the 'Capital Improvement Program', Salt Lake City had constructed major distribution lines and storage capacities spending millions of dollars. But this is only along with major reinforcement within the existing system. Regarding the water supply and management systems, longer term issues of concern are dominated by problems of water availability and development of fiscal resources to meet general levels of water demand, while shorter term problems have as their focal point the satisfaction of temporarily varying demands for water in cost effective ways. And Salt Lake City has been prosperous on favorable circumstances at the expense of other municipalities that have accepted and absorbed new dwellers whose place of works are within Salt Lake City corporate limits. West Valley City is a typical one of such cases. Because Salt Lake City has nothing to do with the former problems, it has been able to avoid newly expanded areas of water service that is the dominant factor making the marginal water service cost very high. On the other hand, West Valley City have to purchase their culinary water at their own expenses. It seems that the people of the West Valley City are unfavorable to enjoy their life with ample water at a low cost. But we can expect that they will overcome those traditional deficient and wasteful water consumption way of life and create new one. They will develop water saving technology and create life style that can use water more effectively and ingeniously.

Large earthquakes along the subducting plate boundary occur repeatedly in the area of an asperity that consists of a strongly coupled zone between two plates. Other areas along the subduction zone are considered to be stable-quasi-stable slip region, which is called a non-asperity, might release strain energy caused by oceanic plate subduction. The physical states of large asperities under the ocean are not well known at present because of the lack of offshore stationary observation networks (e.g., geodetic, seismic and electromagnetic networks).<BR>Strong PP reflections from the subducting plate boundary were found in aseismic zones along the Japan Trench and in the slow slip region in the Tokai region. These features suggest the presence of low-Vp/soft materials and/or fluid along the subducting plate boundary. Such regions might cause continuous or intermittent aseismic slow-slips. If we can map areas of strong PP reflections from observations such as refraction-reflection studies using Ocean Bottom Seismometer (OBS) -airgun surveys, we will be able to obtain the distribution of asperities along the plate boundary.<BR>Assuming that slip acceleration at non-asperity regions might trigger a large earthquake at adjacent asperities, a sudden change of physical states in a non-asperity region might suggest a high probability of plate-boundary earthquakes. Changes due to slip acceleration might be detected by continuously monitoring seismic reflection intensity at non-asperity regions. To perform continuous monitoring, we propose the Accurately Controlled Routinely Operated Signal System (ACROSS), with an integrated active monitoring method using continuously transmitting seismic and electromagnetic sinusoidal waves, which are accurately controlledby a GPS clock with a sophisticated signal analysis method.<BR>The ACROSS seismic source at Toki city in central Japan has been operated continuously for more than 2 years. A field experiment in the Tokai region, central Japan, using this transmission method provided sufficient S/N ratios for the Pg phase traveling 60 km through stacking the data for one month.<BR>Submarine cable OBS systems near the trenches enable us to continuously monitor seismic reflection signatures provided by ACROSS systems located on land. The planned submarine cable OBS in the Tonankaki region might be a good real-time receiver system.<BR>The Exploration of Asperities-Reflectors System (EARS) is proposed for integrating the necessary research components-mapping, monitoring, and real-time continuous monitoring of the Earth's crust. In this paper, we describe the analytical method and important points in such a study.
