Seven subjects participated in a two-part study to evaluate mouth alcohol dissipation in alcohol positive subjects. In part one, subjects rinsed their mouths with a vodka solution and were breath tested after 1, 2, 3, 4, and 5 min intervals. On average, breath alcohol concentration (BrAC) decreased 20.4% (range 3.2-47.9%) between 1 and 2 min after rinsing. In part two of the study, multiple breath tests were administered after rinsing once with the vodka solution. The BrAC decreased more than 0.020 g/210 L between the first and second tests for all subjects (average 0.095 g/210 L, range 0.021-0.162 g/210 L). The average time for subjects to reach their unbiased BrAC was 9.35 min (range 4-13 min) after rinsing. This study reaffirms the need for duplicate breath testing and confirms that the minimum of a 15-min observation period is sufficient for mouth alcohol to dissipate in alcohol positive subjects.  相似文献

人们常常把对抗制和纠问制诉讼模式的不同作为西方两大法系最根本的不同点,进而依据两个模式又发现、列举出一系列衍生的区别.其中当然有正确的观点也有错误的理解.达马斯卡在本文中首先考察了自由放任时代两大法系所存在的相同点和不同点,进而跟踪之后两大法系发生的变化来甄别那些已经逐渐消失的区别,最终为我们揭示能够成为根本不同点的特...  相似文献

The fortunes of information transfer and technology are inextricably bound. The extent to which technology transfer is accomplished depends largely on the effectiveness, selectivity, and efficiency with which information is transferred. This article reviews DoD agents that bring about the transfer of its information; in doing so, they contribute to the transfer of DoD’s technology to state and local governments and to the private sector. It emphasizes the role played by the Defense Technical Information Center.  相似文献
