Isobutane CIMS is useful for determining the molecular weight of morphine and its derivatives, as well as for identifying labile acyl substituents on morphine's O-6 position. Furthermore, this technique will provide information relating to the presence or absence of pi-bonding on the C-7 carbon. The spectra of morphine derivatives can be further simplified by employing ethylenediamine as a reagent gas. This approach proves useful for eliciting or confirming molecular weight information from the CI spectrum. In our laboratory extended use of ethylenediamine has been accomplished without any deleterious effect on the mass spectrometer's source or its vacuum system. The utility of isobutane and ethylenediamine CI rests with its ability to supply the analyst with structure elucidation data that may be used to complement more detailed information extractable from either EI or CE spectra. This aspect of mass spectrometry is especially useful when one is dealing with an unknown member of a particular class of organic compounds.  相似文献

In the following article, we take the example of a novel about a female spree killer to explore some fundamental issues in contemporary feminist politics around the issue of violence as a textual or practical strategy for feminism. We consider what it means for a woman to commit acts of violence against a man from a number of theoretical perspectives. We conclude that the novel Dirty Weekend illustrates that access to the male order and transgression of it must go together for any effective feminist politics.  相似文献

This article is concerned with Satow's seven years as diplomatic interpreter in the Japan of the fateful 1860s. He was sent first to Peking because the Foreign Office in its ignorance thought that Japanese was very similar to Chinese, but this detour did at least enable him to meet there another notable British diplomatic interpreter, Thomas Wade. He soon learned better about Japanese, and once he had mastered it fluently he became a privileged observer of traditional society and culture in the crucial period when it was being shaken by the first rumblings of the Meiji era. He was therefore able to render outstanding service to his head of mission, who was himself an ex-interpreter. Satow went on to enjoy a long and distinguished career in the diplomatic corps, rising from interpreter to ambassador.  相似文献

With the U.S. Supreme Court's 1996 decision in Jaffee v. Redmond, all U.S. jurisdictions have now adopted some form of evidentiary privilege for confidential statements by patients to psychotherapists for the purpose of seeking treatment. The majority of states, following the decision of the Supreme Court of California in Tarasoff v. Regents of the University of California, have also adopted some form of duty by psychotherapists to breach confidentiality and warn potential victims against foreseeable violence by their patients. Largely unresolved is whether there should be a dangerous patient exception to the evidentiary privilege parallel to the Tarasoff exception to confidentiality. This Article argues that exception to the evidentiary privilege should be evaluated separately from the exception to confidentiality. Whether or not a Tarasoff duty to warn existed at an earlier time, exception to the evidentiary privilege should be made only where psychotherapists' testimony is necessary to prevent future harm to patients or identified potential victims. Applying this standard, the dangerous patient exception generally would not apply in criminal actions against patients, but would apply only in proceedings for the purpose of protecting patients or third parties, such as restraining order hearings or proceedings to hospitalize patients.  相似文献
