[en] The overall of this Department of Energy (DOE) Phase II SBIR program was to develop a new class of highly robust fiber-based adsorbents for recovery of heavy metals from aqueous waste-streams. The fiber-based adsorbents,when commercialized,will be used for clean up metals in aqueous waste-streams emanating from DOE facilities,industry,mining,and groundwater-cleanup operations.The amount of toxic waste released by these streams is of great significance.The U.S.Environment Protection Agency (EPA) reports that in 1990 alone,4.8 billion pounds of toxic chemicals were released into the environment.Of this waste,the metals-containing waste was the second largest contributor,representing 569 million pounds. This report presents the results of the Phase II program,which successfully synthesized noval fiber-based adsorbents for the removal of Group 12 metals(i.e.mercury),Group 14 metals (lead),and Group 10 metals(platinum and palladium) from contaminated groundwater and industrial waste streams.These fiber-based adsorbents are ideally suited for the recovery of metal ions from aqueous waste streams presently not treatable due to the degrading nature of corrosive chemicals or radioactive components in the feed stream. The adsorbents developed in this program rely on chemically resistant and robust carbon fibers and fabrics as supports for metal-ion selective ligands.These adsorbents demonstrate loading capacities and selectivities for metal ions exceeding those of conventional ion-exchange resins.The adsorbents were also used to construct filter modules that demonstrate minimal fouling,minimal compaction,chemical and physical robustness,and regeneration of metal loading capacity without loss of performance

[en] The moisture content of forage is an important factor for determining its quality. However, an accurate real-time measurement has been difficult. In this paper, a new method for determining moisture content of forage is proposed using attenuation of a transmitted microwave. This method was used to investigate the accuracy of stationary measurements in verifying the moisture content of forage. Microwave attenuation corresponds to the moisture content and physical properties of materials. Result showed that using this method for the moisture measurement of forage is effective

[en] We present a study of single-W production (e⁺e^-→e^-ν_eW⁺) as a new probe of the anomalous coupling at the LEP energy region. The cross-section measurement of single-W process is found to give complementary bounds on the anomalous coupling to those obtained from W-pair analysis at LEP 2. (author)

[en] Physics issues of the e⁺e^- linear colliders are reviewed in the hundreds GeV to TeV region, as a part of the effort to design the future plan of Japanese high energy physics. In this report, we rather begin with the question of ''physics below TeV.'' and ''hadron versus e⁺e^- colliding beams''. We then try to perform detailed analyses on simulated events of various test reactions to see what we could realiastically perform with a e⁺e^- collider in TeV region. Then follow reconstruction of the final state and implications of the exercise. (Mori, K.)

[en] Use of the Hamburger-Salmon soft agar assay method for in vitro chemotherapy sensitivity testing of samples of renal cell carcinoma has been somewhat limited by a relatively low proliferation/evaluability rate for this tumor type (approximately 50%). The tritiated thymidine ([³H]-TdR) incorporation assay method of Tanigawa et al. (Cancer Res., 42: 2159, 1982) was compared to a standard optical colony counting assay technique. Fifty-seven different primary and five metastatic fresh samples of human renal cell carcinoma were studied. Evaluability rate by the [³H]-TdR assay was 90% (greater than or equal to 300 cpm control). In comparison, evaluability rate by optical colony counting was 43% for this group of tumors. [³H]-TdR incorporation increased with increasing tumor grade and increasing stage. Spindle cell tumors showed significantly higher cpm than other cell types. Twenty-three primary tumors were evaluable by both [³H]-TdR and colony counting methods. The correlation coefficient (r) for regression lines for drug sensitivity data points (optical counting vs. [³H]-TdR) of these individual experiments ranged from 0.50 to 0.99 with a mean r +/- S.D. of 0.76 +/- 0.15. For all 260 paired drug response observations of 23 tumors exposed to different drugs, the correlation was very good with r = 0.71. Since the [³H]-TdR assay has an evaluability rate of approximately 90% for renal cell carcinoma, gives drug sensitivity information which correlates well with the colony counting endpoint and yields chemotherapy sensitivity information four days after sample accession, the [³H]-TdR assay may be a more useful method for study of human renal cell carcinoma in vitro chemotherapy sensitivity testing than standard colony counting techniques

[en] We have searched for anomalous penetrating particles in a wide velocity range of 4.10^-4<β<1 with two layers of plastic scintillation counters placed underground. A special trigger logic was utilized to identify anomalously wide signals expected for slow penetrating particles. No candidate has been found, setting the flux upper limit of 1.7.10^-13 cm^-2sr^-1s^-1 for magnetic monopoles. Similar upper limits are obtained for other supermassive relics such as integrally or fractionally charged particles

[en] The electronic structure of doped Mott-insulator La_1-xSr_xTiO₃ has been studied by resonant soft-X-ray emission spectroscopy (SXES). At the t_2g-resonance SXES spectra, the d-d transition whose Raman shift is about 2.0 eV reflects the magnitude of half on-site Coulomb energy (U_dd). The U_dd does not change much around the metal-insulator transition at x=0.05 in La_1-xSr_xTiO₃. This result is thought to be in accord with the prediction of dynamical-mean-field theory

[en] The results of searches for supersymmetric (SUSY) particles carried out by three groups AMY, TOPAZ and VENUS at the TRISTAN e⁺e^- collider are presented. Each group analyzed data taken at c.m. energies between 52 and 60 GeV with the integrated luminosity of about 15 pb^-1. Among many SUSY particles, charged SUSY particles were mainly searched for. No significant signature was observed and so the new mass limits were obtained

[en] Surprisal analysis is applied to inclusive nuclear reactions of (e,e'), (α,α'), and (Li,Li'). By introducing constraints on the excitation energy and its square root, excellent fits to the experimental data are obtained. It is suggested that a substantial part of the so-called quasielastic (quasifree) scattering cross sections is due to more complex processes
