Accumulation of enriched 235U-UO2F2 in the body had injurious effects on theimmune function of central and peripheral immune cells. After an intravenousinjection of beaU--UO,F,, the spontaneous ’H--TdR incorporation in thymocytes andbone marrow cells decreased, with the thymocytes damaged more markedly. Theproliferation ability of spleen T and B lymphocytes were both inhibited, with Blymphocytes inhibited more severely. In spleen B lymphocytes the IL-- 1 production andIL--2 consumption were diminished. The inhibition of spleen B lymphocyteproliferation by 'U-- UOZFZ was partially restored by adding exogenous IL-- 1 or IL--2to the cultured lymphocytes obtained from 'U injected mice.

We hypothesize that for disaster risk mitigation,many households,despite being aware of their risk and possible mitigation actions,never seriously consider doing anything about *** mitigation-focused decisions,since there is no equivalent to warning messages,the decision process is likely to evolve over an extended *** explore what activates hurricane mitigation protective action decisions through three research questions:(1)to what extent are homeowners unengaged in protective action decision making?(2)What homeowner characteristics are associated with lack of engagement?And(3)to what extent do different life events trigger engagement in the decision-making process?We use the Precaution Adoption Process Model to conceptualize engagement as distinct from decision making;the broader protective action decision-making literature to explore drivers of engagement;and Life Course Theory to examine potential transitions from unengaged to *** use survey data of homeowners in North Carolina to examine these questions *** suggest that one-third of respondents had never engaged in protective action decisions,that life experiences differ in their occurrence frequency and effect on households’mitigation decisions,and that some events,such as renovating,reroofing,or purchasing a home may offer critical moments that could be leveraged to encourage greater engagement in mitigation decision making.
