Liquid chromatography-mass spectrometry was used to identify and quantify the predominant capsaicinoid analogues in extracts of fresh peppers, in oleoresin capsicum, and pepper sprays. The concentration of capsaicinoids in fresh peppers was variable. Variability was dependent upon the relative pungency of the pepper type and geographical origin of the pepper. Nonivamide was conclusively identified in the extracts of fresh peppers, despite numerous reports that nonivamide was not a natural product. In the oleoresin capsicum samples, the pungency was proportional to the total concentration of capsaicinoids and was related by a factor of approximately 15,000 Scoville Heat Units (SHU)/microg of total capsaicinoids. The principle analogues detected in oleoresin capsicum were capsaicin and dihydrocapsaicin and appeared to be the analogues primarily responsible for the pungency of the sample. The analysis of selected samples of commercially available pepper spray products also demonstrated variability in the capsaicinoid concentrations. Variability was observed among products obtained from different manufacturers as well as from different product lots from the same manufacturer. These data indicate that commercial pepper products are not standardized for capsaicinoid content even though they are classified by SHU. Variability in the capsaicinoid concentrations in oleoresin capsicum-based self-defense weapons could alter potency and ultimately jeopardize the safety and health of users and assailants. 相似文献

The State Industrial Home for Women at Muncy in Pennsylvania opened in 1920 just as the reformatory movement began to wane and quickly became the sole correctional institution for women in the state, besides county jails. Despite the broader population that Muncy housed, traditional reformatory ideals were still supported and enforced. Yet the practices and programming of the institution also exemplified the changing economic and social role of women in society. Using recently uncovered primary sources from the institution, this article places Muncy within the broader context of the reformatory movement and argues that its dual emphasis played a significant role in its respect and longevity as an institution. 相似文献

The research program organization has been generalized to implement research policies in OECD countries. Principal investigators are the linchpin of the program based organization as they are developing research project to fit within programs. However, principal investigators are not only project managers but they also enact their environment, shape organization, heterogenous networks, research avenues, research communities and transepistemic arenas. Principal investigators are not only researchers they are also boundary spanners amongst academic and private sectors and amongst subfields and disciplines. Principal investigators, especially serial Principal investigators act as scientific entrepreneurs who enact their environment. It questions the relationship between principal investigators and their organization. It also questions the efficiency and effectiveness of program based research policy. 相似文献

As China expands its official development assistance (ODA) in Southeast Asia,is Chinese aid beginning to emulate international norms and practices or instead establishing its own distinct approach to development assistance? This essay argues that China’s socialization into international norms varies with the thickness of the institutional environment. In Cambodia and Laos,China’s aid program shows signs of alignment with international aid practices. At the regional level,however,China is beginning to act more like a norm-maker. Through expanding its financial support for select regional initiatives,Beijing is bolstering its ability to shape the norms and practices of regional developmental institutions. China’s rising ODA in Southeast Asia poses a potential challenge to Australia’s influence in the region,but also provides opportunities for greater diplomatic engagement and cooperation in support of regional development. 相似文献
