Within the framework of the modified potential cluster model with forbidden states,the total cross-sections of radiative n^(9)Be capture to the ground and five low-lying excited states are calculated at energies from 10^(-2)eV up to 5 *** thermal cross-section σ_(th)=8.35mb is in good agreem.nt with experim.ntal *** considered five resonances at the excitation energies E_(x)from 7.371 meV up to 10.570 meV corresponding to the following states with J^(π)(E_(x),meV):3^(-)(7.371),2^(+)(7.542),3^(+)(9.4),2^(+)(9.56),and 3^(-)(10.570).The partial and total ^(9)Be(n,γ0+1+2+3+4+5)^(10)Be reaction rates are calculated at temperatures from 0.001 to 10 T_(9).Contrary to the available data,we propose that the rise in the reaction rate near factor five at T_(9)>1 is mainly due to the first 3^(-)(E_(R)=0.559 meV)*** foresee this contrast as arising from different model approaches.

尽管过去几年射线防护措施已普遍改善,但由于介入放射学的发展,使放射学工作者又面临新的射线损害。在困难的经皮经管腔动脉成形术和局部松解术中,人们往往需要30分钟甚至更长的透视时间。射线防护的基本原则就是尽可能的远离射线源和有效射线,以及尽可能地缩小照射范围和缩短照射时间,这是在介入放射中不能永久遵循的。

The antioxidant capacity and changes in chemical composition of two grape varieties, the new hybrid BRS-Carmem and the Bord6 grape （Vitis labrusca） and of their products （juice, wine and vinegar） were evaluated by several techniques. The DPPH method was used to measure the antioxidant capacity, whereas, the total phenolic contents （TPC） were measured by Folin-Ciocalteau method. Overall chemical composition was also m.nitored by ESI-mS fingerprints and UPLC-mS analysis. For both grape varieties, the highest （and similar） antioxidant capacity and TPC were observed for the wine and vinegar samples followed by the grapes and then the juices. In addition, ESI-mS fingerprints and UPLC-mS analysis in the negative ion mode indicated substantial changes in chemical composition from grape to juice and wine, and then to vinegar.

Placic horizons, defined as thin, wavy, hardened layers of iron and organic matter, are rare within the United States, occurring only in Washington, Alaska, and Hawaii. While ironstone is comm.n in m.ny soils of the southeastern United States, it is not known to contain appreciable organic matter. As a pilot study evaluating the justification for a larger study on ironstone in Louisiana, a 40 m lateral exposure with suspected placic horizons was evaluated in Vernon Parish, Louisiana. Results of laboratory analysis show elevated levels of iron and organic matter in the suspect horizons that meet the criteria of placic horizons as defined by the Soil Survey Staff. Based on the results of this study, additional evaluation of multiple pedons with similar features is warranted. Should additional pedons dem.nstrate similar properties, a new great group of 'Petrudepts' would be needed to describe both the placic horizons in the pedon and the udic moisture regime in which they occur.

＜正＞During fabrication and posterior heat treatm.nts of mmCs, it is possible that reaction products and intherphases can appear in case the matrix is a high strength heat-treatable alloy. The effects of the type and volume fraction of Ti-Al intermetallic reinforcem.nts on the reactivity layer formation of Ti-Al/6061 Al metal matrix composites （mmCs） was investigated. With the aim of studying more deeply reinforcem.nt effects over composites used in this work, different analysis were performed. These were based upon microhardness tests in order to estimate mechanical properties as well as cycle polarization to evaluate corrosion resistance.
