Cor triatriatum is an uncommon congenital anomaly. Abbott (1946) reported only seven cases in 1000 necropsies of congenital heart disease and there were only four examples in 3740 autopsies performed at the Buffalo Children's Hospital from 1936 to 1948. It has been estimated that 75 per cent of cases die in infancy (Keith et al., 1958) and eighteen of the thirty-nine cases so far reported have ...
A red phosphor, K2SiF6:Mn4+, was prepared by the hydrothermal method. The as-obtained K2SiF6 confirmed as cubic phase. In K2SiF6:Mn4+ strongest excitation peak lies in 350 nm and emission 632 which is due to 2Eg→4A2g transition. optimum luminescence conditions were obtained changing Mn4+ doping concentration. Employing with blue chip commercial yellow phosphor fabricates a white-light LED. asob...
We study the statistical mechanics of the one-dimensional discrete nonlinear Schrödinger (DNLS) equation with saturable nonlinearity. Our study represents an extension of earlier work [Phys. Rev. Lett. 84, 3740 (2000)] regarding the statistical mechanics of the one-dimensional DNLS equation with a cubic nonlinearity. As in this earlier study, we identify the spontaneous creation of localized ex...
Subjects judged "ratios" and "differences" in pitch between pairs of tones that varied in frequency. Half of the subjects listened to stimuli that ranged from 191 tb 844 Hz; the other half received a range that varied from 191 to 3740 Hz. For both ranges, the rank orders ofjudgrnents in the two tasks were essentially the same. If subjects actually use ratio and difference operations on the same...
The 1986 Design Automation Conferhancements, improved design cycles, and ence, held last July, was the first major emphasis in quality for design and test. computer conference to buck the trend of The exhibit area held 660 booths with reduced attendance. A grand total of 3840 95 exhibitors. During the opening of the paid attendees (1985 attendance was 3740) exhibits, the conference featured a n...
ABSTRACT Current methods for the determination of sound power such as the ISO 3740 series do not have a direct traceability to a primary standard. The different methods are regarded as equal, but they do give results with systematic differences. One task of the European project “EMRP JRP SIB 56 SoundPwr” has been to develop and investigate traceable and consistent methods for sound power measur...
برای بهرهبرداری بهتر از شبکههای توزیع آب توصیه میشود که شبکههای موجود به نواحی مجزا تبدیل شود. بهدلیل پیچیدگی شبکههای قدیمی، تبدیل این شبکهها به نواحی مجزا، پرهزینه و حساس است. در پژوهش حاضر مدلی ارائه شد که با استفاده از تئوری گراف و نرمافزار شبیهسازی هیدرولیکی EPANET، تبدیل شبکههای قدیمی به نواحی مجزا را بهصورت بهینه انجام میدهد، بهصورتی ...
Los componentes alfa (α) y beta (β) de la diversidad gamma (γ), partición β en anidamiento recambio, contribuyen a entender los factores que determinan biológica. El objetivo este estudio fue afectan cambios espaciales macroinvertebrados lagos andinos tropicales alta montaña, partir del β. Para esto, se realizó un muestreo noviembre 2018, lago ubicado 3740 m.s.n.m. Se recolectaron bentónicos 20...
