A series of studies were conducted using dual energy X-ray absorptiometry (DXA) to measure energy and protein deposition in pigs. In an initial validation study DXA was compared directly with slaughter analysis as a method for measuring energy deposition in pigs. During growth from 30 to 60 kg the mean value for carcass energy deposition measured by DXA was 251 MJ compared to 249 MJ by chemical...

Nanocrystalline cadmium sulfide thin films as antireflection materials for solar cells have been prepared by a new chemical solution deposition route in an aqueous medium at 50 °C. as-deposited thin films were studied using X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), and optical absorption spectra. X-ray diffraction data indicated the formation of hexagonal na...

Zinc oxide nanostructures are deposited on glass substrates in the presenceof oxygen reactive gas at room temperature using the radio frequency magnetronsputtering technique. In this research, the effects of zinc oxide sputtering pressure on thenanostructure properties of the deposited layer are investigated. The deposition pressurevaries from 7.5 to 20.5 mTorr. AFM resu...

OBJECTIVE To estimate the energy requirements of infants from total energy expenditure and energy deposition during growth. DESIGN Energy requirements during infancy were estimated from total energy expenditure measured by the doubly labelled water method and energy deposition based on measured protein and fat gains. SETTING Database on the total energy expenditure and energy deposition of ...

Low-pressure sputtering and ionized vapor deposition processes create atomic fluxes with kinetic energies in the 1.0–20 eV (and above) range. The impact energy of these hyperthermal atoms significantly effects the surface morphology and structure of vapor deposited films. Recent molecular dynamics simulations of metal atom interactions with a metal surface have established the energy and angula...

In this paper, the effect of magnetic field on the morphology, structure and magnetic properties of electrodeposited FeCu/Cu thin films was investigated. The films were deposited on Au2PdAg/glass substrates using electrodeposition technique in potentiostatic control. The magnetic fields of 5000 and 7000 Oe were applied on deposition bath during deposition. Two series of thin films were prepared...

Deposition of 36-microm gold-coated hollow microspheres in two porous media (glass beads and quartz sand, 710-850 microm) was examined using X-ray microtomography (XMT) in the presence of an energy barrier to deposition under fluid velocity conditions representative of engineered filtration systems. XMT allowed examination of the deposition at different locations at the grain surfaces (depositi...

The energy deposition on the ISIS muon target and the temperature profiles are analysed in this paper. The thermal modelling is performed using the GEANT4 Monte Carlo code. Heat deposition patterns are also simulated for alternative target geometries. Energy deposition in the collimators is also discussed.
