A new approach is described in this work to predict impact sensitivity of a variety of polynitroaliphatics, polynitroaromatics and the explosives containing N-NO2. This paper introduces some simple correlations for prediction of impact sensitivity of C(a)H(b)N(c)O(d) explosives using a, b, c, d, molecular weight and structure information of the explosive. The new correlations are applied to test different polynitroaromatics, benzofuroxans and nitramines. The results are compared with experimental data and some models of complex quantum mechanics computation. Predicted impact sensitivities for 46 explosives have a root mean square (rms) of deviation from experiment of 24 cm, which show good agreement with respect to measured values as compared to five different quantum mechanical models. Impact sensitivities for 58 polynitroaliphatics and related explosives are also calculated, and have a rms deviation from experiment of 40 cm.
In this introduction, we examine health activism as one expression of an emergent 'politics of vitality' or flurry of activity around health matters that includes: advances in technoscientific medicine, healthcare restructurings, and a re-thinking of science-society contracts. In querying politicized mobilizations around 'health matters and the mattering of health,' we provocatively entitle our discussion 'patient organization movements'. This marks an invitation to interrogate (in reverse order) each term along the way, pausing in our concluding discussion to turn our attentions to the patient. The figure of the patient is thematized as an historical inscription and a formidable dimension of personhood under modernity/late modernity. Moreover, we argue that conventional categorizations of the patient are undergoing accelerated processes of change at the present time. We characterize three transformational trends: moves to author and authorize patienthood, mutiny from patienthood, and mutations in the category of the patient. Such metamorphoses in patienthood represent both reflections and repercussions--at once consequences and catalysts--of the proposed politics of vitality. We explore the pluralization of the patient's persona via a closer look at the 11 empirical studies of health activism that comprise this collection.
In this paper I discuss the question of how we should understand the concept of "social movements", particularly as applied to health related movements. My argument is that movements should be understood as "fields of contention". This concept, as I develop it, emphasizes two key aspects of social movement mobilization. Firstly, departing from traditional models of movements, which tend to view them as unified "things", it draws our attention to the numerous groups and agents who interact within the internal space of a "movement" and to the relations, alliances and conflicts between those various groups/agents as they unfold through time. Secondly, it draws our attention to the embedding of social movement struggles within multiple differentiated contexts of struggle, each of which affords different opportunities for struggle but each of which makes different demands upon activists if struggle is to prove effective. The model of fields of contention is explored within the paper using empirical data on a variety of "social movement organizations" (SMOs) which have formed around the mental health system in the UK over the last forty years.
