Nosologlcal data on outpatients and inpatients in the Psychiatric Service of Nara Medical University Hospital in fiscal 1999, are reported in this paper. There were 967 outpatient cases and inpatients were 232 inpatient cases. According to the diagnostic classification using F codes of the ICD-10, F4 (neurotic, stress-related and somatoform disorder) was most frequent (255 cases, 27％) in the outpatients, followed by F3 (mood disorder; 221 cases, 23％), F0 (organic, including symptomatic, mental disorder; 135 cases, 14％) and others. On the other hand, F2 (schizophrenia schizotypal and delusional disorder) was most frequent (69 cases, 30％) in the inpatients, followed by F4 (neurotic, stress-related and somatoform disorder; 51 cases, 22％), F3 (mood disorder; 38 cases, 16％) and others

Surface Plasmon Resonances of Cu Nanowire Arrays

Surface plasmon resonances of arrays of parallel copper nanowires, embedded in ion track-etched polycarbonate membranes, were investigated by systematic changes of nanowires’ topology and arrays area density. The extinction spectra exhibit two peaks which are attributed to interband transitions of Cu bulk metal and to a dipolar surface plasmon resonance, respectively. The resonances were investigated as a function of wire diameter and length, mean distance between adjacent wires, and angle of incidence of the light field with respect to the long wire axis. The dipolar peak shifts to larger wavelengths with increasing diameter and length, and diminishing mean distance between adjacent wires. Additionally, the shape effect on the dipolar peak is investigated

高温注氦及随后230MeV的~(208)Pb~(27+)辐照Al_2O_3的光致发光谱的研究

主要研究了110keV的He~+高温注入Al_2O_3单晶及1.1MeV/u的~(208)Pb~(27+)辐照注氦Al_2O_3样品的光致发光的特性。从测试结果可以清楚地看到在375nm,413nm和450nm处出现了强烈的发光峰。并且在600K,5×10~(16) ions/cm~2剂量点,样品的发光峰是最强的。这表明He~+注入Al_2O_3后使带隙中深的辐射中心复合的效率大幅度提高,极大的增强了其发光强度,而且发光伴随着蓝移现象。而经过高能~(208)Pb~(27+)辐照后的样品,在390nm出现了新的发光峰,从FTIR谱中我们能够看到,可能是~(208)Pb~(27+)辐照相对沉积膜出现一定的晶化,其中含有许多纳米尺寸的Al_2O_3晶粒所致

快重离子辐照聚合物材料时,由于密集电离激发在其路径上产生几纳米直径的潜径迹,径迹形貌受离子种类、离子能量等多种因素的影响.为了研究电子能损对径迹形成所起的作用,利用1.158GeV的Fe56离子和1.755GeVXe136离子在室温真空环境下辐照叠层聚酰亚胺(PI)薄膜,结合傅里叶转换红外光谱(FTIR)分析技术对辐照引起的化学变化进行了测量.聚酰亚胺官能团的降解及炔基的生成是离子辐照聚合物的主要特征,在注量1×1011到6×1012/cm2范围及较宽的电子能损(dE/dX)e范围(Fe56离子:2.2到5.2keV/nm,Xe136离子:8.6到11.3keV/nm)对官能团的断键率及炔基生成率进行了研究.红外结果显示在实验涉及的能损范围都有炔基生成,应用径迹饱和模型对实验结果进行拟合,不同能损下的平均损伤径迹半径及炔基生成径迹半径被得到,通过热峰模型对实验结果拟合,给出了离子在聚酰亚胺中产生潜径迹的能损阈值,实验给出的径迹形貌的电子能损效应曲线与热峰模型预言走势基本一致
