CuO formation control as a function of mixed ratio of Cu-free powders in the synthesis of YBCO superconductors on Cu substrates

YBa₂Cu₃O_x (Y123) superconducting films were fabricated on Cu substrates using a simple screen-printing method, from Cu-free powders (Y₂O₃ and BaCO₃). In the process, CuO, which causes superconducting properties of Y123 films to deteriorate, was formed on the film surface. By varying the atomic ratio of Y to Ba (Y:Ba = 1:1∼1:4), the ratio needed to prevent CuO formation was found for the film surface that had been heat-treated at 980^∘C for 17 s. The film, with the ratio of Y to Ba (Y:Ba = 1:1), is reheat-treated at 930^∘C for 9 min 30 s to form a superconducting Y123 phase. It was possible to prevent CuO formation by controlling the ratio of Cu-free powders in the mixture and to fabricate YBCO superconductors on Cu substrates using a two-step heat-treatment.

为保证不间断电源可靠地工作,需要在线监测蓄电池的浮充电压。由于不知道准确的函数表达式,不能根据测量参数判断出蓄电池的状态。本文作者通过在微型计算机上运行的matlab软件,采用反向传播人工神经网络计算出精确的数据。再将这些数据存放在单片机内存中,通过查表的方法解决了蓄电池电压监测的困难。该方法在蓄电池电压监测仪中得到了应用。     

Composition of the Council of Representatives: Report on the Apportionment Ballot for Representation Year 2006.

Each year, the apportionment ballot is used to determine how many representatives each division and state, provincial, or territorial association will have on the Council of Representatives. This article reports on the apportionment ballot for representation year 2006. The annual apportionment ballot to determine the composition of the 2006 Council resulted in a total of 162 seats. This compares with a total of 162 in 2004. Including the 13 members of the Board of Directors, the number of Council seats will be 175 for 2006.

Awards for Distinguished Scientific Contributions.

The Awards for Distinguished Scientific Contributions are presented to persons who, in the opinion of the Committee on Scientific Awards, have made distinguished theoretical or empirical contributions to basic research in psychology. Award winners from 1956-2005 are listed. Also included here are the citations awarded to the 2005 APA Awards for Distinguished Scientific Contributions. A brief biography and a selected bibliography of each award winner is included. If an address was delivered, the award winner's address to the 113th annual APA Convention is also published. The award winners were Charles G. Gross, Douglas L. Medin, and Robert S. Siegler. Gross delivered an address entitled Processing the Facial Image: A Brief History (see record 2005-14550-003). Siegler delivered an address entitled Children's Learning (see record 2005-14550-006). (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Award for Distinguished Professional Contributions to Independent or Institutional Practice in the Private Sector.

This award recognizes outstanding service delivery by a licensed psychologist who is primarily engaged in the practice of psychology in a private sector setting. The award is intended to recognize outstanding practitioners in psychology. In previous years, this award was called the Award for Distinguished Contributions to Applied Psychology as a Professional Practice. The name was changed in 2003 to better describe this award. Award winners from 1972-2005 are listed. This document includes the citation awarded to Edward A. Wise, winner of the 2005 APA Award for Distinguished Professional Contributions to Independent or Institutional Practice in the Private Sector. A brief biography and a selected bibliography of Wise accompany the citation. Also published here is an address, entitled Effectiveness of Intensive Outpatient Programming in Private Practice: Integrating Practice, Outcomes, and Business (see record 2005-14550-037), which was delivered by Wise at the 113th annual APA Convention.

The APA/APAGS Award for Distinguished Graduate Student in Professional Psychology is awarded on an annual basis by the Board of Professional Affairs (BPA) and the American Psychological Association of Graduate Students (APAGS) to a graduate student who has demonstrated outstanding practice and application of psychology. Award winners from 2002-2005 are listed. This document includes the citation awarded to Renée E. DeRouin, winner of the 2005 APA Award for Distinguished Scientific Applications of Psychology. A brief biography and a selected bibliography of the DeRouin accompany the citation. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Accredited Internship and Postdoctoral Programs for Training in Psychology: 2005.

Presents the official listing of accredited internship and postdoctoral residency programs. It reflects all committee decisions through July 17, 2005. The Committee on Accreditation has accredited the doctoral internship and postdoctoral residency training programs in psychology offered by the agencies in this article. The original date of accreditation, listed for each program, is the day on which the program's accredited status became effective. Also listed for each program is the date of the next regularly scheduled site visit. Program review is governed by the "Guidelines and Principles for Accreditation of Programs in Professional Psychology" (G&P). (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

L'échelle de dramatisation face à la douleur PCS-CF: Adaptation canadienne en langue fran?aise de l'échelle Pain Catastrophizing Scale.

This study examined the psychometric properties of the PCS-CF, a French-Canadian adaptation of the Pain Catastrophizing Scale (Sullivan, Bishop & Pivik, 1995). One hundred and twenty undergraduate students (83 women; 37 men) completed the PCS-CF and measures of anxiety and depression prior to immersing their hand in ice water for 1-minute. A subset of 39 participants (28 females; 11 males) also completed a second pain task involving an ascending series of electrocutaneous stimulations. Participants' verbal and non-verbal pain behaviours during and immediately after the immersion task were recorded and subsequently independently coded. Reliability analyses revealed that the PCS-CF total score and subscale scores have a high degree of internal consistency and test-retest reliabilities that are comparable to the original Pain Catastrophizing Scale. PCS-CF scores were associated with higher levels of self-reported pain during the ice water immersion task and decreased pain tolerance during electrocutaneous stimulation. Individuals with elevated PCS-CF scores also displayed a more diverse repertoire of pain behaviours than their low PCS-CF counterparts. Previous findings that catastrophizing scores are able to discriminate criterion groups of males and females were also replicated. Given the highly correlated factors obtained in analyses of the dimensionality of the PCS-CF, the structure suggested by the authors of the original scale is only partially supported. However, the results taken together suggest that the PCS-CF is both a reliable and valid measure of the pain catastrophizing construct that is psychometrically comparable to the original PCS.

基坑降水工程设计与实践

电力工程基坑多，深度大，地质条件和施工环境复杂，施工降水已成为深基坑开挖与边坡支护的重要组成部分。作者在基坑降水施工管理实践中发现：以往采用基坑中心水位降低值，预测计算基坑涌水量和基坑水位降深值，只适用于基坑较小、含水层透水性较强场合。当基坑较大，含水层透水性较弱时，基坑在降水施工时地下水位呈凸曲面，再用上述方法计算，基坑涌水量偏小。因此，提出了用基坑周边平均水位降深值预测基坑出水量的计算思路，即采用井点设计降深，计算干扰井影响半径和干扰单井出水量的方法。
