The rapid technological change and uncertain future evolutions have a large impact on investment projects in the telecommunication sector. When new infrastructure networks are rolled out, the initial assumptions can prove to be untrue in the future, severely impacting the payoff. It is therefore extremely important that projects offer flexibility to allow the management to react to unforeseen c...

a digestion trial using cannulated lactating cows was conducted to evaluate the influence of barley grain processing on characteristics of ruminal fermentation and the site and extent of digestion. the experiment consisted in 4 periods and lasted 84 days. the total mixed rations contained 39.86% of grains and 42.90% of alfalfa hay and the rest of ration was composed mainly by cane molasses, fat...

This article focuses on the analysis of evolution inclusions present in eutectoid pearlitic steel subjected to a real cold drawing process. To this end, wires belonging different stages manufacture chain were studied, starting from an initial hot rolled bar (not drawn at all). In addition information obtained through visual inspection, quantitative microdefects generated by these was carried ou...

In-plane aligned, c-axis oriented YBazCu307 (YBCO) films with superconducting critical current densities, Jc, as high as 700,000 amperes per square centimeter at 77 kelvin have been grown on thermo-mechanically, rolled-textured (00 1) Ni tapes using pulsed-laser deposition. Epitaxial growth of oxide buffer layers directly on biaxially textured Ni, formed by recrystallization of cold-rolled pure...

We demonstrate that free graphene sheet edges can curl back on themselves, reconstructing as nanotubes. This results in lower formation energies than any other nonfunctionalized edge structure reported to date in the literature. We determine the critical tube size and formation barrier and compare with density functional simulations of other edge terminations including a new reconstructed Klein...

In a 162-day finishing study, steers were fed various levels of dried distillers grains with solubles (DGS) with ground ear corn harvested at 45% moisture, and compared with steers fed 25% DGS, rolled corn, and corn silage. Steers fed the highest level of DGS (37.5% of diet DM) with ground high-moisture ear corn had the lowest ADG and DMI, but F:G tended to be improved by feeding 25% and 37.5% ...

BACKGROUND Loss of nipple projection is a common problem following nipple reconstruction. The aim of this study was to demonstrate that the use of a tightly rolled dermal graft is effective in the long-term maintenance of nipple projection. METHODS Nipple reconstruction was performed using the C-V flap technique. A dermal graft was harvested from the dog-ear portion of previous scars. The gra...
