Anti-HGV Polyclonal antibody

A CFD modelling is presented for simulating the effects of fire in curved bi-directional road tunnels. A fire source due to a heavy goods vehicle (HGV) with a peak of the heat release rate (HRR) of 50 MW is simulated. The influence of position of the HGV fire in the tunnel, tunnel geometry, longitudinal ventilation of jet-fans, and the presence of traffic flow, are more especially investigated. The effects of these variables on hot gas temperatures, air flow velocity, visibility distance, toxic gases concentrations, and the people evacuation process, are shown. The worst fire scenario was identified to be when the HGV was located in the middle of the tunnel length and in the driving lane centre. This was due to the combined effect of ventilation and geometrical characteristics. The presence of traffic, in contrast with the isolated HGV, caused higher temperatures, interfered with the air flow by decreasing its velocity, and decreased more rapidly the visibility distance in the tunnel. However, toxic gases were found to be below the minimum values that may represent a potential danger to human life. People evacuation from the tunnel was found to be safe when the time before starting to walk is short and the walking speed is a rather high. (C) 2012 Elsevier Ltd. All rights reserved.

Objective: This study examined patterns of violence victimization and aggression in both intimate partner and nonpartner relationships among U.S. military veterans using latent profile analysis to identify subtypes of violence involvement. Method: Participants were 839 substance use treatment seeking veterans (93% male) from a large Veterans Affairs Medical Center who completed screening measures for a randomized controlled trial. Results: Past-year violence involvement, including both intimate partner violence (IPV) and nonpartner violence (NPV), was common in the sample, although NPV occurred at somewhat higher rates. When we included either IPV or NPV aggression or victimization, more than 40% reported involvement with physical violence, 30% with violence involving injury, and 86% with psychological aggression. Latent profile analysis including both aggression and victimization in partner and nonpartner relationships indicated a four-profile solution: no/low violence (NLV; n = 377), predominantly IPV (n = 219), predominantly NPV (n = 134), and high general violence (HGV; n = 109). Multinomial logistic regression analyses revealed that, compared with the NLV group, the remaining three groups differed in age, cocaine use, posttraumatic stress disorder (PTSD) symptoms, and legal involvement. Legal issues appeared to differentiate the profiles most, with the predominantly NPV and HGV profiles reporting more instances of driving under the influence and the HGV profile reporting legal problems related to aggression. Conclusions: IPV and NPV are fairly common among veterans seeking substance use treatment. The clinical characteristics of violence profiles indicate that cocaine use, PTSD symptoms, and legal involvement are treatment needs that vary with violence profile and may be useful for clinical decision making.
