A four-channel microelectronic system for neural signal regeneration

This paper presents a microelectronic system which is capable of making a signal record and functional electric stimulation of an injured spinal cord. As a requirement of implantable engineering for the regeneration microelectronic system, the system is of low noise, low power, small size and high performance. A front-end circuit and two high performance OPAs (operational amplifiers) have been designed for the system with different functions,and the two OPAs are a low-noise low-power two-stage OPA and a constant-g_m RTR input and output OPA. The system has been realized in CSMC 0.5-μm CMOS technology. The test results show that the system satisfies the demands of neuron signal regeneration.

人尿集落刺激因子对受照射小鼠存活的影响

本实验证明人尿集落刺激因子（ＣＳＦ）能明显地提高受照射小鼠存活率，并延长存活时间。用微孔板有限稀释法培养粒细胞证明人尿ＣＳＦ能维持外周血粒细胞存活，且存活细胞数与ＣＳＦ浓度有密切关系。在含有人尿ＣＳＦ的条件下，骨髓粒－巨噬细胞存活数（ＣＦＵ－ＧＭ）在培养１２ｄ时培养８ｄ者增多。     

Multimodal Integrative Cognitive Stimulating Group Therapy: Moving Beyond the Reduction of Psychopathology in Schizophrenia.

The authors present a group therapy for schizophrenia called multimodal integrative cognitive stimulating group therapy (MICST). MICST is founded upon a theoretical model that views schizophrenia as a condition characterized by information-processing and memory deficits, which interfere with communication. MICST is designed to stimulate clients' cognitive and memory functioning, improve information processing, and enhance clients' abilities to engage in reality-based conversations. The therapy combines elements of social skills relaxation exercise, cognitive rehabilitation, and traditional psychotherapy but also emphasizes accessing clients' "intact" cognitive functioning by using both visual and auditory modalities. MICST's long-term use, its eager acceptance by clients and staff, and results from various outcome measures support its potential value. However, formal studies are required to more firmly establish MICST's efficacy. (PsycINFO Database Record (c) 2010 APA, all rights reserved)

满足已有制造依据的飞机外形曲面重建原则

在航空企业推广无纸设计、制造技术的第一步,是建立飞机外形的数字化模型。本文详细介绍了某型号飞机在建立符合设计要求,满足已有制造依据的数字化模型过程中应该遵循的原则,即协调关系不变、曲线、曲面原始定义不变、按设计特点构造曲面、参照理论模线设计规定误差。     

用普通分光光度计精确测定塑料白度的一种方法

采用分光光度计对塑料白度进行测定,是精确度比较高的一种方法。通过测定样品的各个波长光谱反射率,同时选取特定的标准光源与CIE标准观察者光谱三刺激值,从而计算出样品颜色三刺激值。在此基础上采用Taube白度公式(CIE推荐)即可计算出样品白度。     

长纤维增强PP-GMT片材膨胀化行为研究

通过膨化率的测量，得到了长纤维增强PP-GMT片材最佳膨化时间为8min；考察了玻纤含量、空隙率、玻纤长度及毡结构对PP-GMT片材膨化的影响，结果发现，随着玻纤含量增加和空隙率减小，片材的膨化率提高；玻纤长度和毡的结构对膨化影响显著，玻纤长度为18nm的短切毡膨化性能最佳；在此基础上，对长纤维增强的PP-GMT片材的膨化机理进行了初步的推理。
