Five marijuana samples were compared using bulk isotope analysis compound-specific isotope ratio analysis of the extracted cannabinoids. Owing to the age of our cannabis samples, four of the five samples were compared using the isotope ratios of cannabinol (CBN), a stable degradation product of Δ(9)-tetrahydrocannabinol (THC). Bulk δ(13)C isotope analysis discriminated between all five samples at the 95% confidence level. Compound-specific δ(13)C isotope analysis could not distinguish between one pair of the five samples at the 95% confidence level. All the measured cannabinoids showed significant depletion in (13)C relative to bulk isotope values; the isotope ratios for THC, CBN, and cannabidiol were on average 1.6‰, 1.7‰, and 2.2‰ more negative than the bulk values, respectively. A more detailed investigation needs to be conducted to assess the degree fractionation between the different cannabinoids, especially after aging. 相似文献

DNA-based analysis was performed using partial mitochondrial cytochrome b genes of five mammalian specimens and Chromo-Helicase-DNA-binding (CHD) genes of five pheasants to determine whether specimens were from illegally hunted animals. Mammalian specimens were identified as being those of horse, roe deer, and cow through gene amplification using cytb981f and cytb981r primer set and sequencing. CHD genes were revealed to be those of three male and two female pheasants through polymerase chain reaction amplification. Because hunting of roe deers and female pheasants is prohibited in Korea, these results provided forensic evidences of illegal wild animal hunting. 相似文献

WELFARE STANDARDS, SUBSTANTIVE TESTS, AND EFFICIENCY CONSIDERATIONS IN MERGER POLICY: DEFINING THE EFFICIENCY DEFENSE 总被引:1,自引:0,他引:1
For several years already, the efficiency defense (and its incorporationin the law) has been a much debated issue in merger policy.When discussing the introduction of an efficiency defense inmerger control, it is important to define clearly its contentand interpretation. However, different approaches to the conceptof efficiency defense exist in the literature, and it is notalways clear which jurisdictions apply an efficiency defense.Therefore, to improve communication and comparison between jurisdictions,it would be useful to reach agreement on the exact content ofan efficiency defense. This paper proposes to define the efficiencydefense along two dimensions: a conceptual onerelatedto the welfare standardand a procedural onerelatedto the application of the substantive test. The main conclusionof this paper is that the concept of efficiency defense canonly be appropriately applied under a total welfare standardand if efficiencies can be directly balanced against the anticompetitiveeffects of mergers on a case-by-case basis. Using this definition,only in Canada and Australia (formal review process) would anefficiency defense exist. 相似文献

激情犯,是指行为人因受外界的刺激,在极度强烈的情绪状态下实施的犯罪,包括社会激情犯和反社会激情犯,由于对反社会激情犯不能从宽处罚,而对社会激情犯从宽处罚已有相应规则可供适用.因此,规定激情犯没有必要.另外,没有适当的立法模式以及激情犯认定的困难,加上主观认定标准反而与规定激情犯原意背道而驰,故规定激情犯没有可行性. 相似文献

This article examines the political and diplomatic struggles in urban South Vietnam from the perspective of women in the Vietnamese Women’s Movement for the Right to Live (WRL) during the Vietnam War. This movement was a timely response to the American war of aggression, which had destroyed the fabric of South Vietnamese society and drastically diminished women’s position within it by 1970. Under the leadership of Mrs. Ngô Bá Thành, the WRL fought for peace and women’s liberation through political action and shrewd diplomacy. Unlike female guerrilla fighters, the WRL maintained political autonomy and neutrality throughout the conflict. As a result, it was violently repressed by the Saigon government and quickly disbanded after the communist victory in 1975. Nevertheless, studying these politically sophisticated women’s anti-war efforts is crucial to understanding the symbiotic yet destructive relationship between Third World women and American imperialism during the twentieth century. It also helps dismantle essentialist assumptions about Asian women as inherently submissive and politically naïve. The WRL is a sterling example of Vietnamese women’s ingenuity in their dual struggle for national liberation and gender equality. 相似文献
