Preliminary clinical studies with a new non-ionic contrast medium (Iopamidol) in intravenous pyelography
The non-ionic and low-osmotic pressure contrast media Iopamilon 370 was used on 20 outpatients who had not been found to have abnormal renal function. The results were compared with those obtained with Urographin (76%), currently used at our department, on 13 of the 20 patients. The nephrograms and renal pelvis obtained using Iopamilon 370 tended to have a clearer contrast than those obtained with Urographin. No side effects were produced
Integration and Application of a Fiber-Optic Sensing System for Monitoring Debris Flows
This study presents an innovative fiber-optic sensing system for monitoring debris
flows. The system mainly comprises an interrogator and four fiber Bragg grating accelerometers. The
field tests show that signal-to-noise-ratio (SNR) of the fiber-optic sensor is 10 dB higher than that of a
geophone. Following confirmation of the reliability of the proposed sensing system, the systems are
deployed along the Ai-Yu-Zi and Chu-Shui Creeks in Nautou County, Taiwan, for monitoring debris
flows. The four accelerometers are installed in series. The systems have detected several debris flows
in 2012. The monitored data reveal that the frequency range of the acceleration of ground vibration is
10-150 Hz, which is the same as that of the velocity of ground vibration detected by a sensing system
that includes geophones. Because the fiber-optic sensing system is more sensitive than the geophone
system, the proposed fiber-optic sensing system is highly promising for use in monitoring natural
disasters that generate ground vibrations.本研究藉由組合光纖光柵加速度計、解調儀、及其他相關元件,發展一套可偵測土
石流之光纖感測系統。現地測試結果顯示,與目前常用含地聲檢知器的土石流感測系統相較,
本系統所測得地表振動訊號之訊雜比比前者高10 dB。在測試系統量測效能後,將此系統分別
架設於南投縣信義鄉神木村之愛玉子溪及出水溪上。系統中採串連方式配置四個光纖加速度
計,並於2012 年監測到多場土石流。觀測結果顯示,光纖感測系統所測得土石流所造成地表
振動之加速度,與過去地聲檢知器所測得土石流地表振動速度,兩者頻率一樣,均為10–150
Hz。由於光纖光柵加速度計相較於地聲檢知器更為靈敏,因此,除了可應用於偵測土石流外,
也可應用於監測會產生地表振動的其他坡地災害,如:落石及山崩等

STUDIES ON THE VITRIOL SPRINGS. (6)
a) Colorimetoric determnation of the minute amount of antimony and antimony contend of Yanahara Hot Spring. To 5cc of sample soln., not containing the second family other than antimony. add 0.2 cc of 10% polyvinyl alcohol aqueous solution. Adjast HCI eoncentration to approximately I. N. Add I cc of hydrogene sulfide solution and sbake. Then measure the reruting yellow or orange color by photometer. Antimony content of Yanahara Hot Spring was 0.1±0.03 g per liter by the above mentioned method. b) Quantitative determination of the free mineral acid. Precipitate iron and aluminium as complex fluorine salts and change the sulfate ion into alkali sulfate, so that it can not liberate free acid. Then titrate with alkali using phenol red as an indicator. c) Iron and coprer in thermal waters and minerals of Yanahara Hot Spring. Ferous ion content of Yanahara Hot Spring (60℃) was 14.6g per liter and its copper content was 0.44g per liter. both being the highest record in Japan. A green and a bluish green minerals ware found, crystalyzed near the Hot Sprig. The latter was apisanite (Cu(0.25) Fe(0.75) S0(4・8.8) H(2)O) and the former proved to be a pure melanterite (Fe S0(4).7H(2)O). d) A modified method to detect sulfides of the second family. Using zinc-amalgam the author succeeded to avoid the liberation of sulphur and to detect the yellowish or orange colored sulfides, such as ausenic, antimony or tin sulfide. e) Paper chromatography applied to the analysis of heavy metals in vitriol waters. 4 kinds of vitiol waters were investigated. Paper chromatography proved to be excellent in detecting the metals of the second family, such as tin, antimony, and ansenic
