A novel method for the estimation of intermediate-long firing distance range is proposed. The method is based on the characterization and chemical analysis of the smokeless powder particles on the target. An adhesive lifter is applied to collect the suspected gunshot residues (GSRs) from the surface of an object, and a Modified Griess Test (MGT) is carried out after alkaline hydrolysis on the adhesive lifter. Visualized particles are removed from the adhesive lifter under a microscope. Two systems are used for the analysis of organic discharge residues from the smokeless powder: (1) gas chromatography/thermal energy analysis (GC/TEA) for the analysis of nitroglycerine (NG) and 2,4-dinitrotoluene (2,4-DNT), (2) gas chromatography/mass spectrometry (GC/MS) for the identification of organic components such as DNT, NG, and some stabilizers. By using this procedure and confirming that the suspected particles are indeed GSR, one can estimate the intermediate-long firing distance of c. 0.75-3 m in the presence of very few particles and provide information for the classification of ammunition type in casework.  相似文献

Borate-containing compounds were formerly used as topical antiseptics and were components of many medicinal preparations including skin powders and ointments used for the treatment of burns and diaper rash. These compounds were also used as irrigants for body cavities, including the pleural, vaginal, and rectal cavities. These applications were subsequently discontinued by the medical community when the toxicity and potential lethality of borates were recognized. Although documented cases of borate poisoning are now rare, the chemical is still an active component commonly used in high concentrations in household disinfectants/cleaners, pesticides, and wood preservatives. While the majority of documented borate-related deaths have occurred in infants, the toddler population is currently at risk due to possible exposure to these household products. We present the case of an 18-month-old child who died following the accidental ingestion of a boric acid-containing, commercially available roach pesticide product.  相似文献

Incidental findings (IFs) of potential medical significance are seen in approximately 5-8 percent of asymptomatic subjects and 16 percent of symptomatic subjects participating in large computed tomography (CT) colonography (CTC) studies, with the incidence varying further by CT acquisition technique. While most CTC research programs have a well-defined plan to detect and disclose IFs, such plans are largely communicated only verbally. Written consent documents should also inform subjects of how IFs of potential medical significance will be detected and reported in CTC research studies.  相似文献

Research technologies can now produce so much information that there is significant potential for incidental findings (IFs). These are findings generated in research that are beyond the aims of the study. Current law and federal regulations offer no direct guidance on how to deal with IFs in research, nor is there adequate professional or institutional guidance. We advocate a defined set of researcher duties based on law and ethics and recommend a pathway to be followed in handling IFs in research. This article traces the underlying ethical and legal theories supporting researcher duties to manage IFs, including duties to develop a plan for management in the research protocol, to discuss the possibility of and management plan for IFs in the informed consent process, and to address, evaluate, and ultimately offer to disclose IFs of potential clinical or reproductive significance to research participants when they arise.  相似文献

Results of our 2003 survey of Ecuadorian banana producers’ farming practices indicate that firms engaged in labeling schemes generate lower environmental risks than uncertified firms. Certified firms exhibit relatively comprehensive environmental management systems, while noncertified farms exhibited limited, uneven, and unstructured adoption of best management practices. We explore the specific circumstances that differentiate the more environmentally friendly firms from their conventional counterparts, and we identify the sustainability pathways available to differently situated firms engaged in banana production. We find that small certified operations mobilize social capital to engage alternative markets and add value to their products, while large certified firms rely on financial backing of international organizations to modernize their operations. For both large and small firms producing bananas in Ecuador, the sustainability gains we observe are premised on mobilization of external resources from actors in the industrialized world. We demonstrate that improved environmental performance of commodity production cannot be attributed to local resources, local dynamics, and local institutions. Our analysis also points to the limits of export of sustainability from rich nations to developing nation firms. Only a fraction of the industry participates in certification programs, and large segments of the population of firms are likely to remain unattractive and inaccessible to external resource providers. In this context, it appears that the state must define and enforce minimum environmental standards to progressively raise performance.  相似文献

The research note comments on W. Veenendaal's article “A Big Prince in a Tiny Realm: Smallness, Monarchy, and Political Legitimacy in the Principality of Liechtenstein”. It is argued, inter alia, that the phenomenon of “princely self‐restraint” should not be underestimated in Liechtenstein's constitutional reality. The character of the microstate's actual political system strongly depends on the individual personality of the Reigning Prince . A strong monarch who acts as a political actor with his own agenda should not be conceptualized as a neutral traditional leader. From the perspective of many citizens of Liechtenstein, the principality's political system is legitimate since it combines traditional authority and legal‐rational authority in a unique way. Largely due to the powerful role of the government, the microstate is characterized by consensus‐oriented hierarchical governance. Elite surveys can be seen as a useful instrument to overcome some of the methodological pitfalls of the elite interview approach.  相似文献
