1980年米原(Ma ibara〉和敦贺(tsuruga)之间的北陆(Hokuriku)高速公路开通,敦贺隧道B线(2925米)与A线联合投入运营。如果敦贺隧道与1977年开通的A线(3175米)平行,B线就有2个单向车道通往富山(toyama)。本隧道采用静电除尘器的纵向式通风。这种类型静电除尘器的使用在世界上还是第一次。当交通量为1,689辆/小时时,通风量为580米~3/秒。但由于在隧道内利用静电除尘器对空气进行处理(280米~3/秒),通风量可降到389米~3/秒。风速为7米/秒时,静电除尘器的效率可达80%以上。集尘站设在距隧道口1,678米处,内有静电除尘风机的双风道系统、动力分配设备、控制装置和集尘器的辅助机器。集尘器处理气体流量为120米~3/秒,风机能量140米~3/秒,风机直径2.8米,输出功率215千瓦。通风条件包括能见度和CO。静电除尘器和可变角风机按能见度和CO仪表的测值自动运转。允许值是每100米光的传输(能见度)最小为40%;CO最大浓度为100PPm。这种使用静电除尘器的纵向式通风系统现已计划在日本很多长公路隧道使用,如关越隧道(10.8公里)和惠那山隧道(8.5公里)等。

A multi-nucleon transfer and cluster decay experiment,^(7)Li(^(11)B,^(14)C^(*)→α+^(10)Be)α,is conducted at an incident beam energy of 55 *** reaction channel has a significantly large 0-value,which favors populating the high lying resonant states in ^(14)*** decay paths,from these resonances to various states of the final nucleus ^(10) Be,can be selected,owing to the experimentally achieved optimal resolution of the Q-value spectrum.A number of resonant states are reconstructed from the forward emitting 10Be+α fragments,and their major molecular structures can be detected according to the selective decay paths and relative decay widths.A state at 22.4(2)MeV validates the previously measured and theoretically predicted band head of the positive-parity σ-bond linear-chain mo-lecular *** additional resonances at 22.9(2)and 24.2(2)MeV are identified and consistent with the predicted 2^(+) and 4^(+) members of the same molecular band,thus providing novel evidences for the existence of the exotic clustering chain structure in neutron-rich carbon isotopes.A few high energy resonances,which also indicate the presence of the σ-bond molecular structure,are observed;however,further studies are still required to clarify their ascription in band systematics.

toxicity is the totality of adverse effects, which can be functional and morphological lesions in a living organism, caused by a substance introduced in relatively high single doses or in small, repeated doses. the aim of this study was to assess the OECD-recommended acute oral toxicity and anti-inflammatory activity of ethanolic extract of Ficus umbellata leaves. Animals were given a single oral dose of 1000, 3000 and 5000 mg/Kg body weight (BW) of the extract. For the anti-inflammatory activity test, rats were given the ethanolic extract of F. umbellata leaves at doses of 100, 300 and 500 mg/Kg or aspirin® at a concentration of 100 mg/Kg PC orally, one hour before injection of 0.05 ml of 1% formalin under the plantar fascia of the rat’s right hind paw. Paw volume measurements were taken one, two and three hours after formalin injection, using an electronic caliper. After 14 days of observation, no deaths were observed in treated rats. the LD50 of ethanolic extract of Ficus umbellata leaf powder is greater than 5000 mg/Kg body weight. this extract has no significant effects on hematological parameters and on the main markers of nephrotoxicity and hepatotoxicity for a single dose of less than 5000 mg/Kg PC. It reduces formalin-induced edema. Evaluation of the percentage inhibition showed that the extract had greater anti-inflammatory activity at 3 hours after the start of the experiment. However, better inhibition of inflammatory oedema of the paw of rats treated with 500 mg/Kg was observed at 5 hours after the start of the experiment, with a percentage inhibition of 69.23 ± 1.02, compared with the reference group treated with aspirin® 100 mg/Kg, which showed an inhibition of 63.50 ± 0.98. these results show that F. umbellata leaves possess anti-inflammatory activity, which would justify their use in traditional African medicine to prevent or treat inflammation.

tetragonal zirconia polycrystals containing 3 mol% yttria (3Y-tZP), which show Superplasticity at high temperatures, were irradiated using 130 MeV Zr+" ions in the tANDEM accelerator facility at tokai Research Establishment, JAERI. the irradiation induced atomic displacement damage was analyzed by tRIM code. Changes in the mechanical properties and fracture behavior caused by the ion irradiation and the effects of subsequent annealing were studied. the distribution of micro-indentation depth as a function of the indentation position from the irradiated surface to the specimen interior was also examined. the occurrence of compressive residual stresses and increases in hardness and fracture toughness were found in the as-irradiated surface region of the specimen. the subsequent annealing revealed that these quantities were decreased gradually with raising the annealing temperature. Probable causes of the generation of the residual stress and the changes in mechanical properties and fracture mode due to the irradiation are discussed.

A new extractant, [N,N-di（2-ethylhexyl）aminolmethylphenylphosphinic acid （DEAPP）, was synthesized to de- velop the mutual separation techniques of In（Ⅲ）, Ga（Ⅲ） and Zn（Ⅱ）. the extraction selectivity for In（Ⅲ）, Ga（Ⅲ） and Zn（Ⅱ） with DEAPP was higher than that of the commercial phosphorus acid extractants such as D2EHPA and PC-88A. the extraction selectivity for metal ions in 1 mob L 1 aqueous ammonium nitrate solution with DEAPP was in the following order： In（Ⅲ）〉 Ga（Ⅲ）〉 Zn（Ⅱ）. these selective extraction behaviors indicate that the amino moiety of DEAPP plays an important role in the mutual separation of ln（Ⅲ）, Ga（Ⅲ） and Zn（ll）. the extraction equilibria of In（Ⅲ）, Ga（Ⅲ） and Zn（Ⅱ） with DEAPP （ = HR） were expressed by the following reactions： In3＋＋ 2（HR）2 InR3（HR）＋ 3H＋, Ga3＋＋ 1.5（HR）2 ＋ N- = GaR2（HR）（NO3）＋ 2H＋, and Zn2＋ 4- 2（HR）2 ZnR2 （HR） 2 determined 4- 2H＋. the extraction equilibrium constants of In（Ⅲ）, Ga（Ⅲ） and Zn（Ⅱ） with DEAPP were to be Kex, M = 1.7 × 104 [*** 1], 4.17 [（***-1）s], and 1.55 × 10 2 [-], respectively.
