Recently we have constructed two facilities for generating photon beams in the MeV and sub-MeV energy regions by means of the Compton backscattering with a laser and an electron beam at SPring-8 and at Kansai Photon Science Institute of Japan Atomic Energy Agency(KPSI-JAEA). the MeV-photon source at SPring-8 consists of a continuous-wave optically-pumped far infrared laser with a wavelength of 118.8 μm and an 8 GeV stored electron beam. Present MeV-photon flux is estimated to be 1.3×103 photons/s. On the other hand,the sub-MeV-photon source at KPSI-JAEA consists of a pulse Nd∶YAG laser with a wavelength of 1 064 nm and a 150 MeV electron beam accelerated by microtron. In the first trial of the photon production in this source,backscattered photon flux is estimated to be 20 photons/pulse. Both the Compton backscattered photon sources have possibilities to be used for new tools in various fields such as nuclear physics,materials science,and astronomy.

2001年日本西南兵库县北部地区发生的一次地震(Mw5．2),一些余震群沿着不同于主震走向的方向发生。首先,我们通过近源强地面运动波形反演对此次事件的破裂过程进行研究。虽然这是一次5级地震,但高密度强震观测台网记录到了高质量的波形数据。为了取得震源反演的精确格林函数,我们通过对小事件实测波形数据的前向模拟来标定地壳结构模型。从0．4至2．0Hz波形数据反演得出的破裂过程似乎较为简单。较大的滑动区位于破裂成核点周围。其次,我们还研究了主震和大余震造成的静态应力变化对后续地震活动的影响。我们利用波形反演得到的主震断层面上的不均匀滑动分布,并考虑到随后大余震的影响,对库仑破裂函数(△CFF)变化进行了计算。因此, 我们得出了震源区库仑破裂函数复杂的时空分布。大多数偏离主震断层的余震都发生在正库仑破裂函数区域内。这种结果表明,这些余震强烈地受到由主震和大余震引起的库仑破裂函数的影响。

以胡萝卜为原料,与沙拉酱复配成质量比为6∶1(t1)、4∶1(t2)、2∶1(t3)的胡萝卜沙拉样品,以不加沙拉酱的胡萝卜为对照(CK),采用体外静态INFOGESt消化模型,评估胡萝卜沙拉中主要活性物质(β-胡萝卜素、总酚和V-C)的生物可及性和消化特性。结果显示:除CK和t3的V-C外,活性物质含量经胃消化后均急剧下降,经肠道消化后又上升;添加沙拉酱明显提高了β-胡萝卜素、总酚和V-C的稳定性和生物可及性,t3组中3种生物活性物质在模拟消化过程中较稳定,生物可及性较高;各组的平均粒径D[3,2]和粒径分布强度均先增大,在模拟胃消化阶段消化60 min时最大,随后减至最小,t3组的D[3,2]在模拟消化过程中较小(0.13~5.03μm)。可见,沙拉酱可提高胡萝卜中β-胡萝卜素、总酚和V-C的生物可及性,并具有较好的消化特性,其中以t3组效果较佳。

Open Journal of therapy and Rehabilitation 2022年第4期10卷 244-256页

作者： takashi kimura Department of Physical therapy ASO Rehabilitation College Fukuoka Japan Department of Rehabilitation Medicine Saga University Hospital Saga Japan

Background and Purpose: to investigate target functional independence measure (FIM) items to achieve the prediction goal in terms of the causal relationships between prognostic prediction error and FIM among stroke patients in the convalescent phase using the structural equation modeling (SEM) analysis. Methods: A total of 2992 stroke patients registered in the Japanese Rehabilitation Database were analyzed retrospectively. the prediction error was calculated based on a prognostic prediction formula proposed in a previous study. An exploratory factor analysis (EFA) then the factor was determined using confirmatory factorial analysis (CFA). Finally, multivariate analyses were performed using SEM analysis. Results: the fitted indices of the hypothesized model estimated based on EFA were confirmed by CFA. the factors estimated by EFA were applied, and interpreted as follows: “transferring (t-factor),” “Dressing (D-factor),” and “Cognitive function (C-factor).” the fit of the structural model based on the three factors and prediction errors was supported by the SEM analysis. the effects of the D- and C-factors yielded similar causal relationships on prediction error. Meanwhile, the effects between the prediction error and the t-factor were low. Observed FIM items were related to their domains in the structural model, except for the dressing of the upper body and memory (p transfer, which was not heavily considered in the previous prediction formula, was found in causal relationships with prediction error. It is suggested to intervene to transfer together with positive factors to recovery for achieving the prediction goal.
