衷心祝贺中国人民对外友好协会成立60周年

<正>黎巴嫩中国友好合作联合会("黎中友联")成立于2003年3月3日,汇集了一批黎巴嫩文化、文艺、女性、前外交官、工程师、医生、企业家和律师界精英人士。长期以来,黎中友联受到了历任中国驻黎大使的鼎力支持,成员受邀出席使馆举办的各类活动。双方合作的第一个成果是乔治·哈特姆博     

何为意思表示

本文对德国目前意思表示构成要件理论进行了全面的综述。并在此基础上,抛弃了传统意思表示理论中行为意思、表示意思和效果意思三分的意思表示内部构成要件。分别在能力上的要件、意图上的要件和实质的条件三个方面对意思表示内部构成要件进行了论述。在能力上的要件方面,认为行为意思这个概念并非适当的规范性标准;对于意思表示的归责,重要的并非是否存在行为意思,而是自由形成意思的能力。在意图上的要件方面,认为表示意识并非恰当的术语,沟通意思和参与意思才是意思表示的在意图上的构成要件。在实质的条件方面,认为不应把实质的决定自由一般性地作为意思表示的生效条件。最后认为意思表示应被理解为效力表示,即"应如此发生效力"的表示。     

快速溶剂萃取-气相色谱-质谱联用法分析血液中的农药

目的：建立生物检材血液中农药的快速溶剂萃取（accelerated solvent extraction,ASE）法。方法通过优化ASE萃取条件,考察萃取温度、时间和萃取剂对回收率的影响,提取血液中的农药进行气相色谱-质谱联用（GC/MS）法定性定量分析。结果血液中8种农药的平均回收率在70.6%~92.4%,变异系数小于5.0%,8种农药在0.5~5.0μg/mL的浓度范围内线性良好。结论该方法具有操作简便快捷、回收率高、重现性好等特点,可用于农药的提取检验。     

第四届证据理论与科学国际研讨会闭幕词

在这种场合,闭幕式的发言者们通常都会谈论,我们所有的与会者享受了一场多么美妙的知识盛宴。假若如此,我们就大大地低估了事实真相,这从过去两天会议讨论的情况就可以看出来,而真相是非常重要的。这次会议无疑是一场美妙的知识盛宴,但却远非如此,它还是来自世界各地、带着相当不同的观点的人士,在一个充满坦诚和友善的完满环境中,针对非常相似的问题各抒己见的美妙聚会。我们确实应该再一次感谢会议的东道主邀请我们与会,并感谢他们为筹划和举办这次会议所付出的辛勤努力!     

Italian population data on two new short tandem repeat loci: D2S1338 and Penta E

A population study on two new short tandem repeat (STR) loci D2S1338 (a tetranucleotide repeat) and Penta E (a pentanucleotide repeat) was performed on 208 unrelated Italian Caucasians. The DNA was amplified by polymerase chain reaction (PCR) and separation and detection of the amplified STR fragments were carried out by use of a PE/ABD PRISM 377 DNA Sequencer 377 automated system (Applied Biosystems Division/Perkin-Elmer). Both loci meet Hardy-Weinberg expectations. There is no evidence for departures from expectations between the two loci. The combined Probability of Discrimination and Probability of Exclusion for the two STR loci are 0.999155 and 0.944925, respectively. The results demonstrate that these two regions can be useful for differentiating among individuals, particularly in concert with other STR loci.     

Analysis of breath alcohol with a multisensor array: instrumental setup, characterization and evaluation

The purpose of this work was to evaluate if it was possible to measure the alcohol concentration in breath by a multisensor array, i.e. an electronic nose. The most important aspects were to clarify technical advantages and disadvantages and if the technique is at all suitable for forensic breath alcohol analysis. Even though the system set-up was far from optimal it is clear that it was possible to quantify breath alcohol with a best-case root mean square error = 16.8 mol ppm ethanol (= 0.037 mg/l). However, the method needs significant development especially of the sensor devices. The sensor array was composed of ten metal oxide silicon field effect transistors (MOSFET) with various catalytic gates and one infrared-based CO2 sensor. The system was evaluated by monitoring the breath ethanol concentration of five test persons after intake of alcohol. Gas chromatography was used in parallel to measure the actual breath alcohol concentration. Different data evaluation techniques applied were projection to latent structure (PLS) and artificial neural networks (ANN).
