The 1H nuclear magnetic resonance (NMR) chemical shifts and coupling constants of heroin's D ring H-15 alpha, H-15 beta, and H-16 alpha, and H-16 beta are presented. These assignments were accessible through the introduction of a double bond (delta 15,16) in heroin. The resulting compound, delta 15,16 didehydroheroin, was subjected to deuterium exchange or stereoselective reduction or both. Reduced products d1-16 alpha heroin d2-15 alpha, 15 beta-heroin, and d3-15 alpha, 15 beta, 16 alpha-heroin are presented. Heroin with deuterated acetyls is also presented for 1H NMR spectral clarity in the D ring area. 相似文献

Abstract This is an evaluative study of a juvenile probationary project in which youth are ordered to pay restitution as a term of probation and, to assure them means of compliance, the juvenile court arranges for and supplies their employment. Demographic variables (age and sex) and court-related variables (plea, length of probation, amount of restitution ordered, and amount and proportion actually paid) are examined in relation to one another and, most important, in relation to recidivism as measured by subsequent law violations for which the offender was investigated, and subsequent law violations that resulted in formal charges against the youth. The data demonstrate that recidivism is related to severity of the initial offense, but more important, it is related to the youth's success in achieving the restitution goal. Successful compliance with the restitution order, when success is measured by amount of restitution paid relative to the amount ordered by the court, is significantly related to revocation of probation, time given to pay, amount ordered to be paid, and subsequent offenses charged. Indeed, the proportion of restitution paid is the most important predictor of recidivism. The data reinforce the dominant legislative position that an offender's ability to pay must be taken into account in ordering restitution. 相似文献

For the determination of total hemoglobin (Hb) in blood containing elevated carboxyhemoglobin (COHb), a newly developed reagent containing a 100-fold concentration of ferricyanide (20 g/l) and a 2-fold concentration of Sterox SE was compared with a standard reagent (0.2 g/l ferricyanide), the reagent of van Kampen and Zijlstra, using forensic blood samples and experimentally heated blood samples. There were no significant differences between the spectra of hemiglobincyanide (HiCN) solution produced with our reagent and the van Kampen and Zijlstra reagent using experimentally heated blood samples. Although the spectra of HiCN changed gradually with increased heating time and with the passage of time after mixing, the absorbance at 540 nm (A540) did not change until at least 120 min for both the reagents. When forensic blood samples containing elevated COHb were mixed with the van Kampen and Zijlstra reagent, total-Hb concentrations determined 5 min after mixing were 10-20% higher than those determined after 180 min. The overestimates of total Hb determined after 5 min resulted in comparable underestimates of percentage saturation of COHb (COHb%) when COHb% was obtained from the ratio of COHb content, determined by gas chromatogrpahy, to total-Hb concentration in blood. However, there was an extremely good correlation between the values of total Hb in forensic blood samples determined with the van Kampen and Zijlstra reagent after 180 min and those determined with our reagent after 5 min. From the results obtained, our reagent proved to be suitable for the determination of total Hb in forensic science practice. 相似文献

Policy analysis has failed to guide gun control policy away from its current impasse because analysts have avoided facing several crucially important features of the current reality: the existence of some widely held values in the United States public that favor the possession of guns; the limitations on the ability of public agencies in the United States to enforce restraints on the possession of handguns; and the implications of the fact that so many guns are already in the hands of the public. These factors greatly reduce the possibility that effective measures will be introduced to reduce the existing supply of guns. Some effective measures of gun control may be possible nonetheless, mainly through the mobilization of large metropolitan police forces. 相似文献

Mental health courts have been proliferating across the country since their establishment in the late 1990's. Although numerous advocates have proclaimed their merit, only few empirical studies have evaluated their outcomes. This paper evaluates the effect of one mental health court on criminal justice outcomes by examining arrests and offense severity from one year before to one year after entry into the court, and by comparing mental health court participants to comparable traditional criminal court defendants on these measures. Multivariate models support the prediction that mental health courts reduce the number of new arrests and the severity of such re-arrests among mentally ill offenders. Similar analysis of mental health court completers and non-completers supports the prediction that a "full dose" of mental health treatment and court monitoring produce even fewer re-arrests. 相似文献

Stability of Delta(9)-tetrahydrocannabinol (THC) in oral fluid using the Quantisal collection device
Moore C Vincent M Rana S Coulter C Agrawal A Soares J 《Forensic science international》2006,164(2-3):126-130
This article details the stability of Delta(9)-tetrahydrocannabinol (THC) in oral fluid during collection, extraction and storage. Oral fluid is being increasingly used as the specimen of choice for the detection of drug use in various applications. Studies to determine the extraction efficiency of THC from the collection buffer and stability under various laboratory storage conditions were carried out. THC was extracted from the collection pad and buffer with an average efficiency over 80% and was stable in Quantisal oral fluid extraction buffer when stored at refrigerated temperatures. Fluorescent lighting caused THC losses of over 50%, however the presence of the pad reduced the loss. In the dark, the loss of THC at room temperature was approximately 20% over 14 days. When stored with the serum separators in place, THC losses were significant. After 3 days, THC concentration was reduced by almost 30%, and after 14 days, 60% of the drug was lost and the losses were not concentration dependent. 相似文献
