In this paper we study the particle transport and deposition in a turbulent square duct flow with an imposed magnetic field using Direct Numerical Simulations (DNS) of the continuous flow. A magnetic field induces a current and the interaction of this current with the magnetic field generates a Lorentz force which brakes the flow and modifies the flow structure. A second-order accurate finite v...

So far, realization of reproducible n-type carbon nanotube (CNT) transistors suitable for integrated digital applications has been a difficult task. In this work, hundreds of n-type CNT transistors from three different low work function metals-erbium, lanthanum, and yttrium-are studied and benchmarked against p-type devices with palladium contacts. The crucial role of metal type and deposition ...

We reconstructed the historical trends in atmospheric deposition of nitrogen to Cape Cod, Massachusetts, from 1910 to 1995 by compiling data from literature sources, and adjusting the data for geographical and methodological di!erences. The reconstructed data suggest that NO 3 -N wet deposition to this region increased from a low of 0.9 kg N ha~1 yr~1 in 1925 to a high of approximately 4 kg N h...

24 We compiled published and newly-obtained data on the directly-measured atmospheric 25 deposition of total phosphorus (TP), filtered total phosphorus (FTP), and inorganic 26 phosphorus (PO4-P) to open land, lakes, and marine coasts. The resulting global data 27 base includes data for c. 250 sites, covering the period 1954 to 2012. Most (82%) of the 28 measurement locations are in Europe and N...

In this study, the model response in terms of simulated mercury concentration and deposition to boundary condition (BC), initial condition (IC), model grid resolution (12km versus 36km), and two alternative Hg(II) reduction mechanisms, was investigated. The model response to the change of gaseous elemental mercury (GEM) concentration from 0 to 2ngm 3 in IC/BC is found to be very linear (r40.99)...

Urban regions of southern California receive up to 45 kg Nha y from nitrogen (N) deposition. A field decomposition study was done using N-labelled litter of the widespread exotic annual grass Bromus diandrus to determine whether elevated soil N is strictly from N deposition or whether N mineralization rates from litter are also increased under N deposition. Tissue N and lignin concentrations, w...

An experiment with 2 trials (28 d/trial) was conducted to determine body composition, tissue deposition, and utilization of Lys for protein deposition (PD) of barrows and gilts fed -Lys·HCl (CLys) or protein-bound Lys in soybean meal (SBM). Thirty-two growing pigs (16 barrows and 16 gilts; average initial BW of 18.6 kg) were used in each of 2 trials. Four pigs (2 barrows and 2 gilts) were eutha...
