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...
0— +1— In August 1993 President Bill Clinton signed a historic law granting the U.S. Federal Communications Commission (FCC) the authority to auction spectrum licenses.1 The origin of this law dates back to Ronald Coase’s 1959 proposal to sell the radio spectrum. Congress gave the FCC until August 1994 to begin the fi rst auction. To someone inexperienced in the activities of large bureaucracie...

Ultra Wide-Band (UWB) communication techniques have received increasing attention since United States Federal Communications Commission (FCC) adopted a “First Report and Order” [1] in 2002. Unfortunately the regulations that appeared a few years latter didn't have the same level of commitment and had much tighter constraints. The FCC part. 15 power spectral density limitation is depicted in Fig...
