The authors developed an integrated system for managing the safe use of radioisotope laboratory facilities, users' access to controlled areas, and the control of air-conditioners. This system consisted of a personal computer, an access controller, an eye retinal verifier, magnetic card readers, hand foot cloth monitors, video tape recorders and a fire alarm system. The access controller was set as the central unit to operate the whole system including 13 gates and air-conditioners. Under this program, only registered persons were permitted to enter the laboratories; the exact records on access were easily obtained; and electricity and fuel expenses were largely reduced. We expect that the system would facilitate the safe use of radioisotopes and the utilization of laboratory facilities. 相似文献

Separation of various alcohols and water through a membrane was carried out by means of a hydrogen-bonding interaction. A membrane obtained from poly(maleimide-co-acrylonitrile) was effective for a selective separation of water from aqueous alcohol solution by pervaporation technique. Spectroscopic analyses verified that this high selectivity was attributed to the hydrogen-bonding interaction between water and maleimide units in the membrane. 相似文献

Questions of asymptotic inference are discussed for a point process model in which the conditional intensity function increases monotonically between events and drops by determined (nonrandom) amounts after each event. Parameter estimates are shown to be consistent and, except under the null hypothesis of a Poisson process, normally distributed. Under the null hypothesis, however, the Hessian matrix is not asymptotically constant, and the limiting distribution of the likelihood ratio statistics is not χ2, but has a form related to that of the Cramer-von Mises ω2 statistic for the test of goodness of fit. 相似文献

Various N-cycloalkyl fumaramides having different characters of N-cycloalkyl groups such as piperidine, morpholine, or pyrrolidone were synthesized and homopolymerized or copolymerized with styrene by use of a radical initiator and ultraviolet irradiation, respectively. N,N′-Dipiperidinyl or -dimorpholyl fumaramides copolymerized with styrene to form a random copolymer, while N,N′-fumaroyl dipyrrolidone tended to form an alternating copolymer with styrene, indicating that the electron distribution of the N-cycloalkyl group affects the polymerizability of fumaramide derivatives. Photopolymerizability of these fumaramides was not as great as that of α,β-unsaturated esters. 相似文献
