Formation of Cyclopent[a]indene and Acenaphthylene from Allyl Esters of Biphenyl. Mono- and Di-Carboxylic Acids and from Biphenyldicarboxylic Anhydrides on Flash Vacuum Pyrolysis at 1000-1100oC
No full textFlash vacuum pyrolysis at 1000-1100°C of the allyl esters of the three isomeric biphenylcarboxylic acids, of the allyl esters of the 12 biphenyldicarboxylic acids and of the three biphenyldicarboxylic anhydrides gave pyrolysates which were examined by 1H n.m.r. spectroscopy at temperatures below -50°C. In all cases the spectra showed the presence of cyclopent[ a ]indene and acenaphthylene together with other products. Possible mechanisms for these ring contraction and cyclization processes are discussed and the results of pyrolyses of [2,3-13C2] biphenyl-2,3-dicarboxylic anhydride, and [3,4-13C2]- and (2-2 H1)-biphenyl-3,4-dicarboxylic anhydrides are reported.Jayant B.

Sustained Spheromak Physics Experiment.
No full textThe Sustained Spheromak Physics Experiment, SSPX, will study spheromak physics with particular attention to energy confinement and magnetic fluctuations in a spheromak sustained by electrostatic helicity injection. In order to operate in a low collisionality mode, requiring T e > 100 eV, vacuum techniques developed for tokamaks will be applied, and a divertor will be used for the first time in a spheromak. The discharge will operate for pulse lengths of several milliseconds, long compared to the time to establish a steady-state equilibrium but short compared to the L/R time of the flux conserver. The spheromak and helicity injector ("gun") are closely coupled, as shown by an ideal MHD model with force-free injector and edge plasmas. The current from the gun passes along the symmetry axis of the spheromak, and the resulting toroidal magnetic field causes the safety factor, q , to diverge on the separatrix. The q -profile depends on the ratio of the injector current to spheromak current and on the magnetic flux coupling the injector to the spheromak. New diagnostics include magnetic field measurements by a reflectometer operating in combined O- and X-modes and by a transient internal probe (TIP)

Mirror Fusion Test Facility magnet system
No full textIn 1979, R.H. Bulmer of Lawrence Livermore National Laboratory (LLNL) discussed a proposed tandem-mirror magnet system for the Mirror Fusion Test Facility (MFTF) at the 8th symposium on Engineering Problems in Fusion Research. Since then, Congress has voted funds for expanding LLNL's MFTF to a tandem-mirror facility (designated MFTF-B). The new facility, scheduled for completion by 1985, will seek to achieve two goals: (1) Energy break-even capability (Q or the ratio of fusion energy to plasma heating energy = 1) of mirror fusion, (2) Engineering feasibility of reactor-scale machines. Briefly stated, 22 superconducting magnets contained in a 11-m-diam by 65-m-long vacuum vessel will confine a fusion plasma fueled by 80 axial streaming-plasma guns and over 40 radial neutral beams. We have already completed a preliminary design of this magnet system
Greenhouse gas fluxes on emerged, unvegetated intertidal flats
No full textFull Text is available to authenticated members of The University of Auckland only.Estuaries are hotspots for the flux of Greenhouse Gases (GHGs – CO2, CH4, and N2O), accounting for half of the coastal emissions of GHGs (Duarte et al., 2005). As such, quantifying the GHG fluxes in estuaries, and predicting future changes in those fluxes, is important for making estimates of global GHG flux. One aspect of estuarine GHG fluxes that is poorly quantified, both in NZ and globally, is fluxes on unvegetated, intertidal flats during atmospheric emergence, and the influence of nutrient enrichment on those fluxes. Benthic incubation methods (commonly used to measure subtidal fluxes) were refined to provide robust measures of the net flux of CO2, CH4, and N2O under emerged conditions. Variability in the direction of the observed fluxes was associated with a change in direction of the tide during emergence. Using refined benthic incubation methods, GHG fluxes were measured at 5 sites across 3 estuaries in NZ, in both summer and winter. Without enrichment, average fluxes of CO2 were -172±76 μmol m-2 h-1 (an uptake) and 183±56 μmol m-2 h-1 (an emission) under light and dark conditions respectively. Average emissions of CH4 and N2O were 0.050±0.14 μmol m-2 h-1 and 0.004±0.0148 μmolm-2 h-1. These fluxes differ either in magnitude or direction to the fluxes from other studies under submerged conditions. E.g., under dark conditions the emission of CO2 from emerged sediments was approximately 1/10th the emission from submerged sediments. Future studies need to account for this difference between emerged and submerged fluxes, particularly where flux estimates are being upscaled across a full tidal cycle. This study found evidence that long-term nitrogen enrichment is likely to increase CH4 and N2O emission and CO2 uptake (under photosynthetically active conditions) on emerged, intertidal flats, with an increase in the CO2 equivalent of 55%. An analysis of environmental conditions associated with fluxes identified relationships between GHG fluxes and the sediment mud content, organic matter content, and the abundance of bivalves. Experimentation using microcosms of Austrovenus stutchburyi in defaunated sediment found no evidence of a direct influence of the Austrovenus density on emerged CO2 and N2O fluxes (although a strong relationship was observed between Austrovenus density and O2 uptake under submerged conditions). A negative relationship was observed between Austrovenus density and emerged CH4 emissions
