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

This paper analyzes sources of error in the two major methods we use to measure crime in America—official police statistics and victimization surveys. The two produce quite different pictures of the volume and distribution of crime, but it is not clear that this is because victim-based statistics are “accurate.” Each measurement procedure has its characteristic errors, some of which it shares with the other. Comparisons of official and survey data on crime are helpful in revealing the dimensions of these error terms, and they point out the analyses which must be conducted if we are to specify their exact proportions. 相似文献
