We report the ASCA results of the bursting X-ray pulsar \gro, which was observed in February 1996 and March 1997. The source flux in the 2--10 keV band was \(2.0\times10^{-8}\) erg/sec/cm\(^2\) in ...1996 and \(5.0\times10^{-9}\) erg/sec/cm\(^2\) in 1997. We detected 12 and 17 Type II bursts during the two observations with mean bursting intervals of about 27 min and 37 min. Each burst is followed by an intensity dip with the depleted flux depending on the burst fluence. The energy spectra are approximated by an absorbed power law with additional structure around 6--7 keV\@. Constant absorption column, \((5-6)\times10^{22}\) cm\(^{-2}\), independent of the observation dates and emission phases (persistent, burst and dip) is interpreted as an interstellar absorption. The source may be actually located near the Galactic center, at a distance of 8.5 kpc. The structure in the energy spectrum at 6--7 keV is most probably due to iron and maybe reproduced by a disk line model with additional broadening mechanism.
Charge coupled devices (CCDs) optimized for soft X-ray detection were utilized for the solid-state imaging spectrometers (SIS) onboard the ASCA satellite, and have been in operation since its launch ...in 1993. We have been carefully monitoring the change in performance of SIS due to radiation damage over three years since launch. Both an increase of dark current and a decrease of charge transfer efficiency are observed, as expected from experiments in the laboratory, but their characteristics are somewhat different from those predicted before launch. This is the first detailed analysis of radiation damage to CCDs actually operated in the space environment and gives important information for the development of similar detectors for space applications.
Documentation is provided concerning successful use of the Canon Communicator by 13 Ss. Questionnaires were completed by the speech-lang pathologists serving these individuals. Ss ranged in age from ...17 to 64 years, & were anarthric or severely dysarthric as a result of a neurological disorder. Although a majority of Ss used more than 1 communication device, all Ss for whom the Canon was appropriate continued to use it more frequently than other devices. 2 Tables, 2 Figures, 4 References.

We have undertaken the following experiment in order to investigate the effect of the Hydrazide for leprosy from May, 1952. We selected the 20 lepromatous leprosy who had not ever received any ...treatment for leprosy. The way of administration were as following : at first we gave them 1mg/kg per os and then after one month gave them 5 or 6mg/kg. The results were summarized as following : 1. The resorption of nodules and infiltrations were observed in 13 patients (65%)after 4 or 6 months, but when they more over continued this treatment we found relaps of leproma in 12 patients after 2 months. 2. We also observed this finding in the histological and bacteriological examination of skin, nasal mucous membrane and blood. 3. This new leproms were resorbed by promin treatment within 2 or 3 months. 4. Erythema nodosum leprosum was observed in only 2 cases (10%). 5. Mitsudas reaction showed no change. 6. Liver and kidney function test showed no change. 7. On second function we could not experiment any important complcation. 8. Lepra bacilli of skin and nasal mucous membrane after 5 months decreased a little but later had a tendency to increase. 9. On blood findings we observed that erythrocytes and hemoglobin decrease a little and lymphocyte and eosinophile cell increase but neutrophile leucoytes decrease. 10. Result in total I. Improvement 13 cases (68%) a. Improvent 1 case (8%) b. Relaps 12 cases (92%) II. Worse 6 cases (30%) III. Stationary 1 case (5%) In short this observation is carried out 10 months in our experiment which leads to the following concusion : Hydrazide is effective for lepromatous leprosy after 4 or 6 months but relaps occur before long (about after 2 months, ).
