One of the dangers of a rapidly growing technology industry is the risk involved in being intimately close to lithium-ion batteries. When exposed to improper conditions, lithium-ion batteries in a variety of devices have been reported to ignite and, in some cases, explode. With the rise of electronic cigarette use and modifications, the lithium-ion batteries in these devices are subject to a higher risk of malfunction. This is a retrograde analysis of a 38-year-old man who experienced fatal penetrating head trauma while using a modified electronic cigarette device. The findings suggest that the trauma from the explosion was caused by the thermal runaway of the lithium-ion battery in the modified e-cigarette.  相似文献

This research examined outcomes and use of specific types of services 6 weeks, 3 and 6 months post-discharge for a large sample of runaway/homeless youth using crisis shelter services. Data were collected for 371 runaway/homeless youth using emergency shelter and crisis services at eleven agencies across a four-state midwestern region. Outcomes were assessed for runaway behavior, family relationships, substance use, school behavior, employment, sexual behavior, and self-esteem. Additionally, the impact of services on outcomes was assessed. Findings indicated that although youth achieved a wide variety of positive outcomes 6 weeks post-discharge, there were signs of attenuation of certain outcomes by the 6 month follow-up. Service use after discharge did not demonstrate a strong impact on maintaining outcomes. The substantive findings reported here present encouraging evidence for providers of services for runaway/homeless youth. Crisis shelter services appear to facilitate broad-based short-term gains, but do not appear sufficient to maintain these gains over an extended period.  相似文献
