Chemical Ionization (CI) GC/MS Analysis of Underivatized Amphetamines Followed by Chiral Derivatization to Identify d and l-Isomers with Ion Trap Mass Spectrometry

Tarver, John A. (John Arthur) 05 1900 (has links)
An efficient two step procedure has been developed using CI GC/MS for analyzing amphetamines and related compounds. The first step allows the analysis of underivatized amphetamines with the necessary sensitivity and specificity to give spectral identification, including differentiation between methamphetamine and phentermine. The second step involves preparing a chiral derivative of the extract to identify d and 1-isomeric composition.

Capillary Ion Electrophoresis of Endogenous Anions and Anionic Adulterants in Human Urine

Ferslew, K. E., Hagardorn, A. N., Robert, T. A. 01 January 2001 (has links)
Normal human urine contains many anions and cations. Ionic concentrations in urine have classically been determined by spectrophotometry of color reactions, flame emission spectrophotometry, atomic absorption spectrophotometry, high performance liquid chromatography, or potentiometry with ion-specific electrodes. Capillary ion electrophoresis (CIE) is a form of capillary electrophoresis which uses the differential electrophoretic mobility of ions to perform a separation of an ionic mixture. Various salts can be added to urine specimens to abnormally elevate ionic concentrations and interfere with either immunoassay urine drug screening procedures or gas chromatographic/mass spectrometric confirmation techniques. Application of CIE for the direct detection of endogenous anions and anionic adulterants in human urine specimens was the purpose of this investigation. CIE was performed using a Waters Quanta 4000 Capillary Electrophoresis System with either direct or indirect ultraviolet absorption detection at 254 nm. CIE of 30 random normal urine specimens and 21 urine specimens suspected of adulteration was performed. Duplicate aliquots were assayed by CIE and by colorimetric technique for nitrite. Sixteen specimens had elevated concentrations of nitrite and/or nitrate. The correlation coefficient between nitrite CIE and colorimetric results was 0.9895. Three specimens had detectable concentrations of chromate and were suspected of being adulterated with "Urine Luck," an adulterant found to contain chromate. Two specimens suspected of being adulterated with bleach were found to only contain chloride, sulfate, and phosphate. CIE is applicable to forensic analysis of urine anion concentrations. CIE can easily quantitate numerous endogenous anions and offers a method to detect and/or confirm anion adulteration of urine specimens.

A Comparison of Student and Student-Athlete Drug Use and Attitudes Toward Drug Testing of Athletes

Munson, J.H. (Jerome Harlan) 08 1900 (has links)
In response to a NCAA ruling, North Texas State University (NTSU) launched a comprehensive drug testing, drug education and counseling program for its athletes effective August 1, 1986. This study assessed and compared NTSU student-athlete and student alcohol and drug use. In addition, attitudes toward a variety of sports-related drug topics, including mandatory athletic drug testing, were assessed and compared. The study revealed significant differences between student-athletes and students in drug use of the following: steroids, marijuana, cocaine, psychedelics, and amphetamines. Both groups favored mandatory drug testing of athletes.

Explaining legal norm transmission using an epidemiological model : the case of employment drug testing

Makela, Finn 02 1900 (has links)
Dans cette thèse, nous construisons un modèle épidémiologique de la dissémina- tion de normes juridiques. L’objectif est d’expliquer la transmission de normes juridiques américaines régissant les tests de dépistages pour drogues au travail vers le Canada ainsi que la propagation subséquente de ces normes à travers la jurisprudence canadienne. La propagation des normes régissant les tests de dépistages pour drogues au travail sert donc à la fois de point de départ pour une réflexion théorique sur la transmission de normes juridiques et pour une étude de cas empirique. Nous partons de la prémisse que les explications du changement juridique, telles celle de la transplantation et celle de l’harmonisation, sont essentiellement métaphoriques. Ces métaphores explicatives fonctionnent en invitant des comparaisons entre les domaines connus et inconnus. Quand ce processus de comparaison est systématisé, la métaphore devient un modèle. Dans la thèse, nous appliquons cette procédure de systématisation afin de transformer la métaphore de la propagation virale en modèle épidémiologique. Après une revue de la littérature sur les épidémies sociales, nous décrivons les éléments pertinents de la théorie épidémiologique pour, ensuite, les transposer au domaine juridique. Le modèle est alors opérationnalisé en l’appliquant à une base de données composée de la jurisprudence pertinente (n=187). Les résultats soutiennent les hypothèses du modèle. 90 % des décisions qui citent les sources américaines sont infectées selon les critères du modèle, alors que seulement 64 % des décisions qui ne citent pas de sources américaines sont infectées. Cela soutient l’hypothèse d’une épidémie dite de « réservoir commun ». Nous avons également démontré une corrélation positive entre la référence à ces décisions et l’état d’infection! : 87 % des décisions qui citent des décisions qui réfèrent aux sources américaines sont infectées, alors que le taux d’infection parmi la population restante est de seulement 53 %. Les résultats semblables ont été obtenus pour les décisions de troisième génération. Cela soutient l’hypothèse selon laquelle il y a eu propagation à travers la jurisprudence suite aux contacts initiaux avec le réservoir commun. Des corrélations positives ont aussi été démontrées entre l’état d’infection et l’appartenance à l’une ou l’autre de sous-populations particulières qui seraient, par hypothèse, des points d’infection. En conclusion de la thèse, nous avançons que c’est seulement après avoir construit un modèle et d’avoir constaté ses limites que nous pouvons vraiment comprendre le rôle des métaphores et des modèles dans l’explication de phénomènes juridiques. / In this thesis, I construct an epidemiological model to explain the transmission of legal norms governing drug testing in the workplace from the United States to Canada and their subsequent spread across the jurisprudence. Employment drug testing norms thus serve as both the starting point for a reflection on how norms spread and a case study for the empirical testing of a theoretical model. I begin with the premise that many explanations of legal change – such as transplant and harmonization – are grounded in metaphors, and then argue that such metaphors work by inviting the hearer to make comparisons between the familiar and the unfamiliar. When this process of comparison is systematized, the metaphor becomes a model. This process of systematization is applied; extending a viral metaphor into an epidemiological model. After reviewing the literature on social epidemics, I set out those aspects of epidemiological theory that may be profitably transposed to the domain of law. I then operationalize the model by applying it to a dataset composed of tribunal decisions (n=187) using computer assisted text analysis. The results support the hypotheses generated by the model. 90% of decisions that cited American sources met the model’s criteria for infection, compared to only 64% of those that didn’t cite American sources. This supports the hypothesis of a common reservoir epidemic. Citation to those infected decisions was also positively correlated to infection: 87% of the citing population was infected, compared to only 53% of the remaining population that cited neither an American source nor one of the infected decisions that cited an American source. Similar results were obtained for third generation decisions. This supports the hypothesis of a serial-transfer epidemic subsequent to contact with the reservoir. Positive correlation to infection was also demonstrated for particular sub-populations hypothesized to be act as points of infection and to a hypothesized vector. In the conclusion, I argue that it is only after we have gone through the process of constructing a model and seen the strengths and limits of its application, that we have access to the full scope of the insights into the role of metaphors and models in the explanation of legal phenomena.
