Passive, Silent and Revolutionary: The 'Arab Spring' Revisited.

This is the author accepted manuscript. The final version is freely available from Taylor & Francis (Routledge) via the DOI in this record.To counter the trend toward mechanization of research and aridity of critical analysis, this article makes a case for an interdisciplinary quest. To borrow Felix Guattari and Gilles Deleuze's phrase, we are convinced that 'everything is political, but every politics is simultaneously a macropolitics and a micropolitics.' With an eye to open-ended research questions, this article attempts to build a body of theoretical, political and anthropological considerations, which, it is hoped, could function as a case of enquiry into the mechanics of power, revolt and revolution. The objective is to draw comparative and phenomenological lines between the events of the 2011 'Arab Spring,' in its local ecologies of protest, with its global reverberations as materialized in the slogans, acts and ideals of Greek and Spanish Indignados and the UK and US occupy movements. In order to do so, it proposes to clarify terminological ambiguities and to bring into the analytical scenario new subjects, new means and new connections. The article resolves to lay the ground for a scholarship of silence, by which the set of unheard voices, hidden actions and defiant tactics of the ordinary, through extraordinary people, find place in the interpretation of phenomena such as revolts and revolutions

Mining cosmic dust from the blue ice lakes of Greenland

Extraterrestrial material, most of which invisible settles to Earth's surface as dust particles smaller than a millimeter in size were investigated. Particles of 1/10 millimeter size fall at a rate of one/sq m/yr collection of extraterrestrial dust is important because the recovered cosmic dust particles can provide important information about comets. Comets are the most important source of dust in the solar system and they are probably the major source of extraterrestrial dust that is collectable at the Earth's surface. A new collection site for cosmic dust, in an environment where degradation by weathering is minimal is reported. It is found that the blue ice lakes on the Greenland ice cap provide an ideal location for collection of extraterrestrial dust particles larger than 0.1 mm in size. It is found that the lakes contain large amounts of cosmic dust which is much better preserved than similar particles recovered from the ocean floor

Meteor ablation spheres from deep-sea sediments

Spheres from mid-Pacific abyssal clays (0 to 500,000 yrs old), formed from particles that completely melted and subsequently recrystallized as they separated from their meteoroid bodies, or containing relict grains of parent meteoroids that did not experience any melting were analyzed. The spheres were readily divided into three groups using their dominant mineralogy. The Fe-rich spheres were produced during ablation of Fe and metal-rich silicate meteoroids. The glassy spheres are considerably more Fe-rich than the silicate spheres. They consist of magnetite and an Fe glass which is relatively low in Si. Bulk compositions and relict grains are useful for determining the parent meteoroid types for the silicate spheres. Bulk analyses of recrystallized spheres show that nonvolatile elemental abundances are similar to chondrite abundances. Analysis of relict grains identified high temperature minerals associated with a fine-grained, low temperature, volatile-rich matrix. The obvious candidates for parent meteoroids of this type of silicate sphere is a carbonaceous chondrite

Hawking radiation in different coordinate settings: Complex paths approach

We apply the technique of complex paths to obtain Hawking radiation in different coordinate representations of the Schwarzschild space-time. The coordinate representations we consider do not possess a singularity at the horizon unlike the standard Schwarzschild coordinate. However, the event horizon manifests itself as a singularity in the expression for the semiclassical action. This singularity is regularized by using the method of complex paths and we find that Hawking radiation is recovered in these coordinates indicating the covariance of Hawking radiation as far as these coordinates are concerned.Comment: 18 pages, 2 figures, Uses IOP style file; final version; accepted in Class.

The composition of meteoroids impacting LDEF

So far we have completed an initial scanning electron microscopy (SEM) survey of craters on the exterior of the Long Duration Exposure Facility (LDEF) in the 100 micron to 1mm size range and done some quantitative analysis. In typical craters, the residue appears to be a mixture of glass and FeNi and sulfide beads with an overall chondritic elemental composition. In less than 10 percent of the craters, there is a substantial amount of meteoroid debris that also contains unmelted mineral grains. The relatively high abundance of forsterite and enststite among these irregular grains suggests that a high melting point probably plays a role in surviving impact without melting
