[en] The papers presented at the meeting have been grouped in four sessions: General (2 papers), Experimental techniques and status of data (9 papers), Theoretical calculation (3 papers), Compilation and evaluation (5 papers), plus a post-meeting contribution. A separate abstract was prepared for each paper. The summary conclusions and recommendations of the three Working Groups are included in the Proceedings. Refs, figs and tabs

[en] The IAEA Advisory Group Meeting on ''Nuclear and Atomic Data for Radiotherapy and Related Radiobiology'' was held at Rijswijk, the Netherlands, from 16 to 20 September 1985, in co-operation with the Radiobiological Institute TNO. The meeting participants reviewed the current and future requirements on nuclear and atomic data for radiotherapy and radiobiology, identified data requirements and their priorities, and issued a number of specific recommendations for future technical work in nuclear and atomic data required to establish a more solid nuclear physics foundation of radiotherapy and related radiobiology. The recommendations in this report are directed to three areas, namely beam production and field description, dosimetry, and interpretation and optimization of biological effects. The final proceedings will be issued as an IAEA publication in 1986. (author)

[en] We propose the spin-Peierls mechanism for the non-trivial magnetization plateaux at M_s/4 and (3/4)M_s (M_s is the saturation magnetization) of the two-leg S=1 spin ladder, bearing in mind the recent experiment on the BIP-TENO

[en] Face-to-face communication is one of the essential style of communication. Trough face-to-face communication, people exchange much information at a time, both verbal and non-verbal information, which is most effective to learn each other. The authors focused on the face-to-face communication, and developed an evaluation method to quantify the effectiveness of communication. We regard conversation as an exchange of keywords. The effectiveness of conversation is valued by the amount of the keywords, and the achievement of mutual understandings. Through two people's face-to-face communication, the author quantified the shared information by measuring the change of the amount of the participants' knowledge. The participants' knowledge is counted by the words they can give. We measured the change in their shared knowledge (number of the words they gave associated to the theme). And we also quantified the discords in their understandings against their partners by measuring the discords between the knowledge that they think they share and the knowledge that they really share. Through these data, we evaluate the effectiveness of communication and analyzed the trends of mutual understanding. (authors)

[en] The EXFOR-VIEN file contains various evaluated neutron nuclear data that are not part of one of the major evaluated nuclear data libraries. This document summarizes the contents of the EXFOR-VIEN file. The data are available, costfree, from the IAEA Nuclear Data Section on magnetic tape or in printed form. (author)

[en] Effects of uv-irradiated and unirradiated T4 phage infection on the β-galactoside accumulation ability in Escherichia coli have been examined by the use of ¹⁴C-labeled thiomethyl-β-galactoside (TMG). Under conditions where a synchronous adsorption of phage takes place, the cellular ability for TMG accumulation is found to be largely inhibited immediately after phage adsorption but it recovers with time to a new level, which is dependent on the multiplicity of infection. When cells are infected with uv-irradiated T4 at the same multiplicity as that of unirradiated phage, the cellular accumulation ability is more severely inhibited and there is no recovery from the inhibition. The recovery process in T4-infected cells is mostly sensitive to puromycin. These results suggest that the initial inhibition of the TMG accumulation ability is probably caused by the adsorption of phage coats, and the subsequent restoration occurs through the action of a phage-directed protein(s). In the recovery process, no new transport system appears to be involved. The restored ability of TMG accumulation is resistant to the action of superinfecting uv phage. However, different mechanisms appear to be operating in T4-infected cells for the establishment of resistance to ghosts and for the recovery from the phage coat-induced inhibition

[en] Estimates are given of the critical values of linear energy transfer (LET), dose rate and dose, below which radiation hormesis is likely to occur but above which it is unlikely to occur. The critical value of LET is estimated to be 15 congruent to 20 keV/micron, and hence radiation hormesis may occur with beta, gamma or x rays, but is unlikely to occur with alpha radiation. The critical value of dose rate is estimated to be 1 congruent to 10 mGy d-1 for the lifetime exposure, but could be higher than this value for the short period exposure. These estimates are consistent with experimental data. The critical value of dose is also estimated, but cannot be compared with experiment because of lack of data. A brief comparison of plants with animals is made, and it is suggested that the value of the critical dose rate for plants in dry conditions, such as seeds or bulbs, could be higher than the above estimate by about a factor 1000. Some sociological considerations are also given

[en] The high-speed camera had a rapid progress in early 2000's. The C-MOS chip camera now can record 7,500 frames per second (fps) with 1 M pixel image resolutions. We can capture 30,000 fps images with VGA image resolution. These images have both of high-temporal and high-spatial resolutions. The two-phase flow and boiling phenomena are usually highly non-linear and need high-temporal and high-spatial resolutions to extract the physics. Therefore, the C-MOS based high-speed camera is the strong tool to extract the complicated basic structures of two-phase flows. One of the key issues of the two-phase flows is the moving boundary. High-speed camera is the strong tool to measure the moving boundary. On the image, both of the boundary motion and tracer particle could be simultaneously measured. Therefore, if the flow field were two-dimensional, only one high-speed camera is needed to capture the structures. The interaction between the flow and moving component, e.g., bubbles, structures and droplets, were precisely evaluated using the Dynamic PIV system. (author)
