Contamination of canine training aids is a pervasive issue that may lead to incorrect canine discrimination of target odors. It is therefore important to properly store training materials to maintain their integrity and efficiency. First, this study demonstrated the potential for contamination using GloGerm™ as a proxy for odor/particulate transfer. Then, eight types of containers were evaluated to determine (1) the ability to prevent odor permeation and (2) the likelihood of maintaining the ab/adsorbed odor. Lastly, a longitudinal study evaluated how the permeation of the target odor changed over time. Analysis occurred using a direct analysis in real-time mass spectrometer (DART-MS) to detect triacetone triperoxide (TATP) from the non-hazardous canine training aid known as the polymer odor capture-and-release (POCR) system. Results showed that Mylar and Opsak bags were most effective for short-term storage, maintaining low levels of ab/adsorption. Over time, the amount of TATP permeating through the primary containers and collecting in a secondary container (i.e., outer packaging) increased at 1 week and decreased thereafter (up to 4 months). The amount of TATP collecting in the primary containers, however, increased up to 1 month and decreased thereafter. 相似文献

Highly polymorphic minisatellite sequences: allele frequencies and mutation rates for five locus-specific probes in a Caucasian population 总被引:3,自引:0,他引:3

Six human minisatellite sequences (MS1, MS8, MS29, MS31, MS43, g3) have been subcloned into a stable host/vector system. Allele frequencies at the hypervariable loci detected by five of these probes were determined in a Caucasian population (200 individuals). Mendelian inheritance has been demonstrated in 5 large multi-generation pedigrees. The mutation rate has been determined in 59 families. The highest mutation rate was observed with MS1, as might be predicted from the observed high heterozygosity and in agreement with previous direct measurement of germ line mutation rates. The data presented on allele frequencies and mutation rates provide preliminary data supporting the use of these probes in paternity analysis and forensic investigations. 相似文献

The Chief Financial Officer Act of 1990 requires the preparation and audit of financial statements for many federal government programs and agencies. The first comprehensive set of financial statements prepared to meet the provisions of the CFO Act were for the fiscal year ended September 30, 1991 and were published in CFO Annual Reports due in August of 1992. This paper presents the results of a study of performance measurement in the fiscal year 1991 financial statements of the sixty-three reporting entities filed as part of the 1992 CFO Annual Reports. The purpose of the analysis of performance measures included in the fiscal year 1991 financial statements was to determine to what extent the financial statements of each of the reporting entities included the various types of performance measures identified in the framework developed for this project. The paper also includes an in-depth analysis of the performance measures reprted by the Social Security Administration and the Department of Labor. 相似文献

Demands for changes and reform in our correctional system have a long history. Currently many of those active in determining policy are advocating a shift away from the use of imprisonment to greater local supervision. However, many of these “elites” perceive the public as unreceptive and thereby an obstacle to change. This study focuses on an analysis of public opinion in the state of Washington and a comparison of those attitudes with the attitudes of elites (decision makers) in the state. Further, the study describes elite perceptions of public opinion and the implications of those perceptions for social policy. The public is found to be far less punitively oriented than elites expected and far more receptive to the reforms advocated. 相似文献
