Abstract Double-cropping winter rye cover crops (CC) with soybean in the North Central US could help global effort to sustainably intensify agriculture. Studies addressing management of these systems are limited. Therefore, a field study was conducted from 2017 2019 Iowa, evaluate CC biomass production, aboveground N accumulation, estimated economics, within-field energy balance and greenhouse ...
The Smagorinsky and One-Equation sub-grid scales (SGS) for modeling of large scale pool fire using Large Eddy Simulation (LES) has been used and compared. The fire heat release rate was 2.07 MWatt and the fuel was Methane. Based on the mixture fraction approach and infinity fast chemistry assumption, the mean velocity profile and turbulence kinetic energy are calculated and compared against exp...
The Interstellar Boundary Explorer (IBEX) mission continues to measure energetic neutral atom (ENA) emissions produced by charge exchange between solar wind (SW) protons and interstellar neutrals at the edge of our heliosphere. Using the first 3 yr of IBEX-Hi ENA measurements (2009–2011), we examined the spectral evolution of ∼0.5–6 keV ENAs at the polar regions (above 60◦). We found the follow...
This study was designed to investigate the effects of eye tracking stimulation on the movement of the body's center of gravity (CG) and the head in aged persons 60 years old and above. Twenty-three healthy aged subjects ranging from 60 to 79 years old and 10 healthy young subjects were asked to pursue a pendulously moving horizontal target when standing with the feet together. The frequencies o...
UNLABELLED The purpose of this study was to assess the quantitative accuracy of truncal FDG PET with a postinjection transmission scan. METHODS Ten subjects with lung cancer were recruited for this study. Prior to the emission scan, a transmission scan was performed for 10 min. All subjects received 370 MBq of intravenous administration of FDG prior to a 60-min emission scan. Immediately foll...
According to J.A.N. Lee in 1996, computer scientists “are reaching the stage of development where each new generation of participants is unaware both of their overall technological ancestry and the history of the development of their speciality, and have no past to build upon” [1, p.54]. A technically and historically accurate account, as attempted here, can help us, computer scientists, grasp ...
A new general reaction for the preparation of isomerically pure hydroxyalkylated C(60) monoadducts, via the free radical photochemical addition of alcohols to [60]fullerene, is described.
The formation of polyelectrolyte multilayers (PEMs) for the first time, two decades ago, demonstrating the assembly on charged substrates in a very simple and efficient way, has proven to be a reliable method to obtain structures tunable at the nanometer scale. Much effort has been put into the assembly of these structures for their use in biological applications. A number of these efforts have...
