A gas chromatographic (GC) fingerprint method, based on the presence or absence of six congeners, was developed for illicit cocaine samples. The fingerprint utilizes the relative abundances of these congeners towards each other, disregarding cocaine as the main constituent, and can be expressed numerically or graphically in the form of pictograms for rapid visual comparison. The method can be applied directly to a solution of the sample in chloroform, without previous workup procedures. More than 70 unrelated samples were analyzed and a great variation was observed in the parameter composition. On the other hand, a remarkable similarity could be seen between related samples. The GC fingerprint method may be considered an important contribution for sample comparison, as is exemplified by a subdivision of the analyzed samples in different categories, based on the number and types of congeners found.  相似文献

During the past decade the field of psychology of law has changed considerably. Accompanying the growth of research and practice, there has been an increase in offerings of courses in this field. The courses are offered at both undergraduate and graduate levels and cover a wide spectrum of interests. The types of courses currently being offered and the student samples enrolling in the courses are examined. In addition, a review of the major textbooks used in the courses is provided.  相似文献

A case of the sudden death of a 14-month-old girl due to massive hemorrhage in a primitive neuroectodermal tumor (PNET) is presented along with a review of the relevant literature. PNET is a rare, malignant brain neoplasm occurring predominantly in children.  相似文献

The polymerase chain reaction (PCR) method of specific gene amplification was used in casework to synthesize millions of copies of the polymorphic second exon of the human leukocyte antigen (HLA)-DQ alpha (or DQA1) locus from a variety of evidence samples. The HLA-DQ alpha allelic variants in the amplified deoxyribonucleic acid (DNA) were determined in a rapid non-radioactive test by hybridization to sequence-specific oligonucleotide probes in both the dot-blot and reverse dot-blot formats. This genetic typing system has been subjected to blind proficiency testing; the performance of this test in the analysis of experimentally mixed samples was also evaluated. As of August 1990, over 250 cases have been tested and more than 2000 individual evidence (bloodstains, semen stains, individual hairs, bone fragments, and tissue sections) and reference samples have been analyzed. The first 198 of these cases are summarized in this paper; in 65% of the cases with conclusive results a suspect was included, and in 35%, all suspects were excluded. Individual cases as well as some of the general issues relating to forensic science analysis and this genetic typing system are discussed. The high rate of exclusion reported here combined with the ability of PCR to type old evidence samples suggests the relevance of this genetic test for postconviction review; two cases in which the convicted suspect was excluded are discussed.  相似文献

An improved method has been developed for the reliable classification of different C1R genetic variant forms from human serum or plasma. The method combines the use of neuraminidase-digested samples followed by monodimensional isoelectric focusing in the pH range 5 to 8 followed by immunoblotting. The method yields a simple pattern, with one major band in homozygote and two major bands in heterozygote cases.  相似文献

The terminology of “civil society” has gained currency in recent discussions of democratic movements around the globe. Although less grandiose in its implications than claims about the “end of history,” this terminology does suggest a certain universality in human experience. We argue that this claim of universality is warranted, but also problematic. We establish the relevance of our argument in reference to the literatures in African and Indian studies. We note first that the common employments of the concept ignore the theoretical and historical specificity of civil society: civil society is used to label any group or movement opposed to the state, regardless of its intent or character, or used so generically that it is indistinguishable from the term “society.” Instead, we argue that civil society is a sphere of social life, involving a stabilization of a system of rights, constituting human beings as individuals, both as citizens in relation to the state and as legal persons in the economy and the sphere of private association. Thus, we link the wide resonance of the concept to its embeddedness in the logic of liberal capitalist society and the capitalist global division of labor. This conception allows us to see that, although the emergence of a sphere of civil society involves at least minimal democranization and is supportive of struggles for further democratization, the status of democracy is also made quite problematic by the tensions endemic to liberal capitalism and the processes of uneven development within international capitalism. Our usage also allows us to distinguish more clearly movements dedicated to the construction of civil society from those that may count actually as counter-civil society movements. David L.
