Verbal Representation and Therapeutic Change in Anaclitic and Introjective Inpatients.

This study examined the relation between changes in clinical functioning and changes in verbal expression in 81 seriously disturbed and treatment-resistant young adults seen in a comprehensive, psychoanalytically oriented inpatient treatment. Clinical functioning was evaluated with a battery of clinical and social measures. Verbal representations were assessed using computer-assisted scoring of Thematic Apperception Test responses. Changes in the frequency of verbal content and style in the narratives of these patients covaried with changes in clinical functioning. Significantly different covariations of verbal and clinical change, particularly differences in covariates of referential activity, were found for patients with anaclitic versus introjective personality configurations. The implications of these findings for understanding and treating severe psychopathology are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

不同类型染料的缺氧生物降解性能研究

对24种常用染料在缺氧条件下的降解性能作了研究，探讨了不同类型、不同化学结构染料生物降解性的内在影响因素，得出了碱性染料和X型染料最易降解，K型染料次之，M型、KN型再次之。此外，染料的分子量、取代基数量、发色母体基团等也是影响染料缺氧生物降解性能的一个重要因素。     

液相颗粒包裹法制备PbNb2O6微粉的研究

本文介绍了一种采用液相颗粒包裹技术制备功能陶瓷微粉的新方法.这种方法有如下特点:(1)方法简便,不需要特殊的设备,便于扩大应用于工业生产;(2)粉体颗粒尺寸小而均匀;(3)粉体化学组成偏离小、且均匀;(4)适应性强,从双组分至十多组分的材料微粉制备均可采用;(5)特别适用于一些含有难溶组分、用液相法无法制备的材料.本工作采用这一方法,成功地制备出 PbNb_2O_6微粉,其平均腰粒尺寸<0.5μm,分散性及化学均匀性好,烧结活性高,烧结温度可以降低近100℃,瓷坯密度可达理论密度的96%以上.

Chemical leaching and magnetic properties of non-equilibrium Al(Co–Cu) powders produced by rod milling

We report upon the chemical leaching and magnetic properties of nanoscale crystalline Al_0.6(Co₂₅Cu₇₅)_0.4 alloy powders produced by rod milling. X-Ray diffractometry (XRD), transmission electron microscopy, differential scanning calorimetry, vibrating sample magnetometry, and superconducting quantum interference device magnetometry were used to characterize the as-milled and leached specimens. After 400 h of milling, only the b.c.c. phase of the intermetallic compound γ-Al_3.892Cu_6.10808 was detected by XRD. After annealing the leached specimen at 600 °C for 1 h, the nanoscale crystalline phase was transformed into the f.c.c. Cu phase, and this was accompanied by a change in the magnetic properties. The peaks of the magnetization shifted towards lower temperature with increasing external field. The temperature behavior at T_f (45 K) for direct current (d.c.) magnetic susceptibility measurements was quite different for field cooling and zero-field cooling. After cooling the leached specimen from 800 °C, magnetization increased gradually.
