建立生物试样中常见巴比妥类药物的固相提取和柱上衍生化GC/MS分析法。将预制的血或肝分别在pH6.0和pH2.2的条件下过预活化的GDX-403吸附小柱,再用缓冲浪和蒸馏水各4ml顺序洗柱。最后用4ml丙酮/氯仿(1:1)溶剂洗脱样品,离心弃除水相,80℃挥至近干,用50μl乙醇定溶、取净化的样品2~4μl挥至近干,加20μl0.2molTMAH衍生化试剂,直接进样0.5μl,柱上衍生化GC/MS(GC)分析。在试验条件下,当血和肝分别添加2.0μg和5.0μg混合药物,回收率≥80%,相对标准差(RSD)优于±10%,检测限优于5ng(信/噪比≥2)。该法能有效地排除类脂物和组胺的干扰,可用于治疗量级药物分析和婴幼儿中毒案检验。 相似文献

Since the Russian-supplied Afghan army overthrew progressive President Daud in 1978, the nation has endured the long Soviet-Afghan war, the Taliban, and the arrival of U.S troops. These military actions have only heightened the historical alienation of the Pashtun tribes who overspread the long-contested border between Afghanistan and Pakistan. These are the people who are almost certainly sheltering Osama bin Laden. The Alienated Frontier is a centuries-old problem that must be solved if we are to win the war on terror, and solving it will require rebuilding the infrastructure, developing alternatives to poppy cultivation, and solving the “Pashtunistan” question. The capture or elimination of given individuals will achieve little if the conditions that allow radicals to thrive are not addressed 相似文献

As globalization accelerates, U.S. foreign policy makers have become less convinced of the influence geopolitics and power politics have on international affairs. They now risk losing touch with rising competitors like China that continue to view the international system in geopolitical terms. Chinese geopolitical strategists have great influence with the country's defense policy makers, who are focusing increasingly on the need for China to establish command of the seas—a goal that threatens conflict between it and the United States throughout Asia. In order to prevent a return to a world dominated by aggressive, geopolitically driven actors, the United States cannot afford to assume that China shares its worldview and that geopolitics has disappeared from international relations. 相似文献

A common theme of research on participatory democracy and citizen engagement centres on the need for empirical studies that conduct a deep exploration of the nuances and complexities of these processes. This article offers a distinct response to this need through an examination of two ethnographic case studies of a participatory budgeting process in a multilingual, highly diverse community in which Spanish-speaking Latino immigrants were involved. By analyzing participants discourse from the case studies, the findings highlight the risks and rewards of reframing participatory processes as design decisions rather than static procedures. 相似文献

Conclusion The creation of improved systems of world order requires great care. Alternative configurations may or may not prove more suitable, and each must be painstakingly examined on its own merits. For those of us who are actively concerned with studying about world order, this means the application of a far more rigorous conception of inquiry to our subject. So long as we cannot accept the Leibnizian claim that this is certainly the best of all possible worlds, our search for better ones must certainly be the best of all possible searches. This means that models of world order must be derived from appropriate hypotheses and subjected to the strictures of systematic analysis. World order studies must be treated in accordance with the strict canons of inquiry outlined in this essay. Only then can they begin to develop the highly generalized system of theory that characterizes any science. 相似文献

This article considers in a different light the relationship between legal theory and ethics by means of an interpretation
of the thought of Adorno and Horkheimer, and of the writings of Richard Rorty, as two moments of a marginal stream of ethics
of passions that runs beneath the history of rationalist Western philosophy. It departs from the critique of Modernity as
a dialectic of barbarism and civilisation, and from a genealogy of Auschwitz that finds its antecedents in Kantian morality.
It also characterises modern culture as one of apathy and bourgeois stoicism, and establishes a link between the cold modern
ethos and the dynamics of Nazi hardness. The article turns then to a consideration of some of the responses to the comprehensive
crisis of Modernity: the imperative ‘Auschwitz never again’, Adorno’s ‘general enlightenment’ and Horkheimer’s ethics of sympathy.
Finally it reflects upon Rorty’s proposal of sentimental education as an effective strategy to foster a human rights culture
in Postmodernity, with the aim of bridging the tradition of moral sentiments and contemporary struggles for human rights.
I am very grateful to Costas Douzinas, Sonia Romero, Shaun Haselhurst, David-Alexander Smith, José Bellido and the two anonymous
