PURPOSE To investigate the use of a commercially available video-based EPID for in vivo dosimetry during treatment of prostate cancer patients. METHODS For 10 prostate cancer patients, the inter-fraction variation within measured portal dose images (PDIs) was assessed and measured PDIs were compared with corresponding predicted PDIs based on the planning CT scan of the patient. RESULTS For ...
Dinitrogen fixation by Nostoc azollae residing in specialized leaf pockets supports prolific growth of the floating fern Azolla filiculoides. To evaluate contributions by further microorganisms, the A. filiculoides microbiome and nitrogen metabolism in bacteria persistently associated with Azolla ferns were characterized. A metagenomic approach was taken complemented by detection of N2 O releas...
Abstract Melt inclusions readily rupture and form gas bubbles during explosive volcanic eruptions, but their role as a source remains enigmatic. Here, we examined pumice texture generated by the instantaneous bursting of melt 946 CE Plinian eruption at Baekdusan. The burst produced non-sheared, super-vesicular (>80 vol.% voids) bubble pockets, occupying volume fractions 6–24% within Millenni...
Energetic hot spots account for a significant portion of the total binding free energy and correlate with structurally conserved interface residues. Here, we map experimentally determined hot spots and structurally conserved residues to investigate their geometrical organization. Unfilled pockets are pockets that remain unfilled after protein-protein complexation, while complemented pockets are...
The Boil-off Gas ( BOG ) compressor is used as a key facility in the liquefied natural gas ( LNG ) terminal, to recycle the excessive boiled gas for re-liquefaction or direct application. The low suction temperature down to -162°C brings about big challenges in design of the BOG compressor. In this paper, the three-dimensional finite element model was used to simulate both the static and period...
Abstract Vacuum pressures are unfavorable in water pipes since they pose a risk to degassing dissolved gases from the and air in-leakage. If flow rate through pipeline is too low, gas bubbles will rise local high points create stagnant pockets. Gas pockets may clog both directly by obstructing cross-section indirectly disturbing chemical equilibria. clogging Lena terrasse groundwater heat pump ...
The shape of the protein surface dictates what interactions are possible with other macromolecules, but defining discrete pockets or possible interaction sites remains difficult. First, there is the problem of defining the extent of the pocket. Second, one has to characterize the shape of each pocket. Third, one needs to make quantitative comparisons between pockets on different proteins. An el...
