BACKGROUND Family-centered care (FCC) involves holistic care and requires cooperation with the family in planning, intervention, and the evolution of the care that is being provided. Many previous studies have provided results that indicate the importance of the family's involvement in pediatric care, but there is still resistance in doing so within the organizational culture of the hospitals i...
Plane-wave pseudopotential Density Functional Theory (OFT) periodic slab calculations were performed usingthe giteralized gradient approximation (GHA) to investigate the adsorption of nitric oxide(NO) on the (I II)surface of Cu. Copper rface was stimulated using th P 'odic Slab Method consisting of Five atomic Layers.Four different adsorption saes (Atop. Bridge, RCP Hollow, and FCC Hollow) were...
By extending the nonequilibrium potential refinement algorithm and lattice switch method to the semigrand ensemble, the semigrand potentials of the fcc and hcp structures of polydisperse hard-sphere crystals are calculated with the bias sampling scheme. The result shows that the fcc structure is more stable than the hcp structure for polydisperse hard-sphere crystals below the terminal polydisp...
Using a Federal Communications Commission (FCC) dataset, this paper demonstrates firms are strategic in the regulatory cases they bring to court. They are increasingly likely to bring cases as the ideological distance between the FCC and the Court increases. Judges then vote ideologically as the firms’ actions predict they will.
در این تحقیق پوششهای نانوساختار آهن-کبالت-تنگستن به روش آبکاری جریان مستقیم بر روی زیر لایه مسی حاصل شد. نتایج نشان داد که چگالی جریان پوششدهی و نیز ترکیب شیمیایی محلول بر خواص مغناطیسی و ساختاری اثرگذار است. مورفولوژی پوششهای بدست آمده از دو حمام آبکاری متفاوت بوده و با افزایش چگالی جریان آبکاری مقدار فاز fcc موجود در ساختار دو فازی fcc+bcc کاهش یافت. مشاهده شد که پارامترهای آبکاری تاثیر چش...
We use the density functional theory and x-ray and neutron diffraction to investigate the crystal structures and reaction mechanisms of intermediate phases likely to be involved in decomposition of the potential hydrogen storage material LiAlH(4). First, we explore the decomposition mechanism of monoclinic LiAlH(4) into monoclinic Li(3)AlH(6) plus face-centered cubic (fcc) Al and hydrogen. We f...
A path integral study of the fcc, hcp, and bcc quantum hard-sphere solids is presented. Ranges of densities within the interval of reduced de Broglie wavelengths 0.2≤λB(*)≤0.8 have been analyzed using Monte Carlo simulations with Cao-Berne propagator. Energies, pressures, and structural quantities (pair radial correlation functions, centroid structure factors, and Steinhardt order parameters) h...
Fecal corticosterone concentration (FCC) is increasingly being used as a noninvasive indicator of stress in assessment of nonhuman animal welfare. The aim of this study was to evaluate effects of breed, cage type, reproductive phase, and their interactions on FCC levels in doe rabbits. A total of 252 doe rabbits were randomly assigned to 2 groups. Does were individually housed in either standar...
AIM The aim of this study was to explore adult-trained perioperative nurses' practice of family-centered care (FCC). METHOD A qualitative research design with a hermeneutic phenomenological approach was used. In-depth interviews were conducted with six adult-trained perioperative nurses. Data analysis was guided by Colaizzi's seven-step framework, resulting in a composite description of perio...
We used mechanical alloying with a Spex 8000 mixer/mill to synthesize a series of Fe1002xNix alloys from x50 to x549. The Spex mill was modified so that it could also operate at a reduced milling intensity, and we compared the alloys synthesized after long times with the normal and reduced milling intensities. X-ray diffractometry and Mössbauer spectrometry were used to measure the volume fract...
