The discrimination of automotive clear coats by pyrolysis-gas chromatography/mass spectrometry and comparison of samples by a chromatogram library software

Identification particles used for the purpose of the post-blast identification of explosives have a coding system based on the combination of metal oxides and their various concentrations. These materials are composed of the polymeric matrix, iron powder (ferromagnetic properties), UV light active dyestuff and various metal oxides in a various ratios. A suitable analytical method has to be used for an accurate characterization of these metal components in the particles in order to find the required information, i.e. to determine the place and the year of production and as the case may be, also the production batch of misused explosives. In this work, the method of microwave digestion and flame atomic absorption spectrometry (F-AAS) was developed for an accurate determination of Zn, Mg, Cu and Pb in a few novel types of identification particles and applied to their characterization. When using specific sample treatment (digestion with a mixture of nitric acid with hydrochloric or hydrofluoric acid), the 3 sigma limits of detection (LODs) for the determination of Zn, Mg, Cu and Pb in 5mg original samples were 1.9, 0.2, 1.3 and 2.4 mg g(-1), respectively. The signal suppression due to the presence of HNO3+HCl or HNO3+HF was observed for Zn; therefore, the calibration solutions had to be prepared exactly with the same acids as those used for the sample mineralization. The determination of Mg, Cu and Pb was free of interferences; hence a simple calibration curve method could be adopted for attaining accurate results. The accuracy was checked by comparison of the results with those obtained by means of independent inductively coupled plasma optical emission spectrometry (ICP-OES). Good precision values, as relative standard deviation, in the range of 1-5% were obtained. A total number of 71 samples was analysed and classified by multivariate methods to prove the suitability of the procedure proposed for the purpose of the identification of explosives.     

The significance of anticipating suspected brain death for the accusation of failure to treat according to Section 323c of the Federal Penal Code

Brain death is usually not confirmed by neurological and angiographical techniques until long after it has actually taken place. In connection with a case in which expert testimony was heard, clinical and radiographic evidence and the autopsy statement are discussed as criteria of continuing development of brain edema; on the basis of the evidence it was possible to conclude that the cerebral circulation had not yet ceased at the time assumed.     

Exploring theoretical linkages between self-control theory and criminal justice system processing

Using Gottfredson and Hirschi's (1990) self-control construct for theoretical leverage, this conceptual article offers a preliminary framework for examining discretion, criminal justice decision-making, and criminal justice system behavior. Low self-control likely facilitates negative interactions between defendants, police, judicial officers, and correctional staff, potentially affecting discretionary outcomes. Research questions are provided for future investigators to begin empirical assessment of the relationships between self-control and criminal justice processing. As a global construct, self-control could be incorporated into criminal justice models as a potentially robust correlate of discretion, decision-making, recidivism, and offender noncompliance with the criminal justice system.     

Medical Marijuana Registries: A Painful Choice?

Though the medical use of marijuana is legal in thirty-three states, it remains illegal under the federal Controlled Substances Act. Any marijuana use can subject individuals to severe criminal and civil penalties under federal law. States that condition patient access and treatment on registration in a state database impose real risks on their citizens. Although many scholars have written about the tension between federal and state treatment of marijuana, this is the first article to examine marijuana patient registry privacy and fundamental rights issues. This article first reviews the relationship between marijuana use and patient treatment, with a focus on health-care and privacy rights under state and federal law. The article then explains how marijuana registries compare to broader patient registries, such as contagious disease and other medical condition patient registries, and the unique issues presented by marijuana patient registries. It then discusses the elevated risk to constitutional, privacy, and fundamental rights that may result if states do not carefully construct marijuana registries. The article concludes by proposing principles for how both states and dispensaries should approach marijuana registries in order to provide health benefits and avoid harm to patients.
