    Notes: Deep penetration welding of polymers can be carried out at high speed with relatively low laser power. This results from an efficient coupling CO2 laser radiation to polymers that leads to volume heating. A brief review of energy coupling and heat transfer effects in polymers under CO2 laser welding conditions is given. Some examples of low power (10 to 100 watt) CO2 welding of polypropylene and polyethylene at depths of up to 1.5 cm are discussed.

A special equipment for the oxidation of powder samples will be described. By our new method it is also possible to prepare YBa2Cu3O7-δ and derivatives of this compound, where Cu is substituted by high amounts of Ni or Ag.

    Sequestration and subduction of deep-sea carbonate in the global ocean since the Early Cretaceous (2018)
    Geological Society of America (GSA)
    In: Geology
    Details
    Publication Date: 2018
    Description: 〈span〉〈div〉Abstract〈/div〉Deep-sea carbonate represents Earth’s largest carbon sink and one of the least-known components of the long-term carbon cycle that is intimately linked to climate. By coupling the deep-sea carbonate sedimentation history to a global tectonic model, we quantify this component within the framework of a continuously evolving seafloor. A long-term increase in marine carbonate carbon flux since the mid-Cretaceous is dominated by a post-50 Ma doubling of carbonate accumulation to ∼310 Mt C/yr at present-day. This increase was caused largely by the immense growth in deep-sea carbonate carbon storage, post-dating the end of the Early Eocene Climate Optimum. We suggest that a combination of a retreat of epicontinental seas, underpinned by long-term deepening of the seafloor, the inception of major Himalayan river systems, and the weathering of the Deccan Traps drove enhanced delivery of Ca〈sup〉2+〈/sup〉 and HCO〈sub〉3〈/sub〉〈sup〉–〈/sup〉 into the oceans and atmospheric CO〈sub〉2〈/sub〉 drawdown in the 15 m.y. prior to the onset of glaciation at ca. 35 Ma. Relatively stagnant mid-ocean ridge, rift- and subduction-related degassing during this period support our contention that continental silicate weathering, rather than a major decrease in CO〈sub〉2〈/sub〉 degassing, may have triggered an increase in marine carbonate accumulation and long-term Eocene global cooling. Our results provide new constraints for global carbon cycle models, and may improve our understanding of carbonate subduction-related metamorphism, mineralization and isotopic signatures of degassing.〈/span〉

    Mantle dynamics of continentwide Cenozoic subsidence and tilting of Australia (2011)
    Geological Society of America (GSA)
    Details
    Publication Date: 2011-10-01
    Description: Australia is distinctive because it experienced first-order, broad-scale vertical motions during the Cenozoic. Here, we use plate-tectonic reconstructions and a model of mantle convection to quantitatively link the large-scale flooding history of the continent to mantle convection since 50 Ma. Subduction-driven geodynamic models show that Australia undergoes a 200 m northeast downward tilt as it approaches and overrides subducted slabs between Melanesia and the proto–Tonga-Kermadec subduction systems. However, the model only produces the observed continentwide subsidence, with 300 m of northeast downward tilt since the Eocene, if we assume that Australia has moved northward away from a relatively hot mantle anomaly. The models suggest that Australia's paleoshoreline evolution can only be reproduced if the continent moved northward, away from a large buoyant anomaly. This results in continentwide subsidence of ∼200 m. The additional progressive, continentwide tilting down to the northeast can be attributed to the horizontal motion of the continent toward subducted slabs sinking below Melanesia.

    Analysis and Observation of Spacecraft Plume/Ionosphere Interactions during Maneuvers of the Space Shuttle (2014)
    Wiley
    Details
    Publication Date: 2014-08-13
    Description: This work employs in situ measurement data and constructive simulations to examine the underlying physical mechanisms that drive spacecraft plume interactions with the space environment in low Earth orbit. The study centers on observations ofthe enhanced flux of plasma generated during a maneuver of Space Shuttle Endeavour as part of the Sensor Test for Orion Relative Navigation Risk Mitigation (STORRM) experiment in May 2011. The Canary electrostatic analyzer (ESA) instrument mounted on the port-side truss of the International Space Station (ISS) indicated an elevated ion current during the shuttle maneuver. The apparent source of enhanced ion current is a result of interaction of the spacecraft thruster plume with the rarefied ambient ionosphere, which generates regions of relatively high-density plasma through charge exchange between the neutral plume and ambient ions. To reconstruct this event, unsteady simulation data were generated using a combined direct simulation Monte Carlo/Particle in Cell methodology, which employed detailed charge-exchange cross section data and a magnetic field model. The simulation provides local plasma characteristics at the ESA sensor location, and a sensor model is subsequently used to transform the local properties into a prediction of measured ion current. The predicted and observed total current are presented as a function of time over a 30 second period of pulsed thruster firings. A strong correlation is observed in the temporal characteristics of the simulated and measured total current, and good agreement is also achieved in the total current predicted by the model. These results support conclusions that: (1) the enhanced flux of plasma observed by the ESA instrument is associated with Space Shuttle thruster firings, and (2) the simulation model captures the essential features of the plume interactions based on the observation data.
