نانو ذرات :Dya%,Tbb%4-x SO1BaxSr به روش هم‌رسوبی سنتز شد. ساختار نانوذرات با استفاده از دستگاه پراش پرتو ایکس (XRD) تعیین شد. اندازه تقریبی نانوذرات با استفاده از روش شرر 5/63 نانومتر محاسبه شد. اندازه و شکل ذرات ساخته شده با استفاده از میکروسکوپ الکترونی روبشی (SEM) مشاهده شد. تست EDX حضور عناصر Dy و Tb در نمونه سنتز شده را تأی...
We review the production of high-mass lepton pairs in fixed-target experiments, including both Drell-Yan (DY) and heavy quarkonium production (J/ψ, ψ, Υ(1S), Υ(2S), and Υ(3S)). In recent years DY data has become standard input to the determination of parton density distributions. DY data has recently yielded the first measurement of the x-dependence of the d̄/ū asymmetry of the proton. Similar t...

Kinoshita Y. Watanabe A. Manabe S. Suga S. Imada We have succeeded in developing a method for photoemission electron microscopy (PEEM) on fully magnetized ferromagnetic bulk samples and have applied this te...
Chapter 2 reports two experiments that examine perceptual learning in humans. In Experiment 1, participants received intermixed exposure to two similar compounds (AX, BX, AX, BX ...) and blocked exposure to a second pair of similar compounds (CY, CY... DY, DY...). Aversions established to AX and CY generalized less to BX than to DY. This confirms that intermixed exposure results in greater perc...
A mutational analysis has been performed to explore the function of the Drosophila melanogaster miniature-dusky (m-dy) locus. Mutations at this locus affect wing development, fertility and behavior. The genetic characterization of 13 different mutations suggests that m and dy variants are alleles of a single complex gene. All of these mutations alter wing size, apparently by reducing the volume...
Experimental transmission of the Stetsonville, Wisconsin, U.S.A. source of transmissible mink encephalopathy (TME) to outbred Syrian golden hamsters resulted in two distinct syndromes, termed hyper (HY) and drowsy (DY), that diverge by the third hamster passage. The syndromes differed with respect to clinical signs, incubation period, brain titre, brain lesion profile and pathogenicity in mink....
In an attempt to destabilize the magnetic state of the heavy lanthanide Dy, extreme pressures were applied in an electrical resistivity measurement to 157 GPa over the temperature range 1.3–295 K. The magnetic ordering temperature To and spin-disorder resistance Rsd of Dy, as well as the superconducting pair-breaking effect Tc in Y(1 at.% Dy), are found to track each other in a highly nonmonoto...
Using public data (Forbes Global 2000) we show that the distribution of asset sizes for the largest global firms follows a Pareto distribution in an intermediate range that is “interrupted” by a sharp cutoff in its upper tail, which is totally dominated by financial firms. This contrasts with a large body of empirical literature which finds a Pareto distribution for firm sizes both across count...
Hypercalcemia is defined as a total serum calcium level greater than 10.5 mg/dL and is often divided into categories to describe the severity of symptoms as mild (10.5 to 11.9 mg/ dL), moderate (12 to 13.9 mg/dL), and severe (>14 mg/dL). The prevalence of hypercalcemia is approximately 0.5% to 3% in hospitalized adults. Hyperparathyroidism is the most common cause of hypercalcemia, and the inci...
