Let a, b, c, d be complex numbers with d 6= 0 and |q| < 1. Define H1(a, b, c, d, q) := 1 1 + −abq + c (a + b)q + d + · · · + −abq + cq (a + b)qn+1 + d + · · · . We show that H1(a, b, c, d, q) converges and 1 H1(a, b, c, d, q) − 1 = c − abq d + aq P∞ j=0 (b/d)(−c/bd)j q (q)j(−aq/d)j P∞ j=0 (b/d)(−c/bd)j q (q)j(−aq/d)j . We then use this result to deduce various corollaries, including the followi...

NADPH-cytochrome P450 (cytochrome c) reductase (EC 1.6.2.4) was solubilized by detergent from microsomal fraction of wounded Jerusalem-artichoke (Helianthus tuberosus L.) tubers and purified to electrophoretic homogeneity. The purification was achieved by two anion-exchange columns and by affinity chromatography on 2',5'-bisphosphoadenosine-Sepharose 4B. An Mr value of 82000 was obtained by SDS...

Using X-ray temperature and surface brightness profiles of the hot intracluster medium (ICM) derived from ASCA and ROSAT observations we place constraints on the dark matter (DM) and baryon fraction distributions in the poor clusters Abell 1060 (A1060) and AWM 7. Although their total mass distributions are similar, AWM 7 has twice the baryon fraction of A1060 in the best-fit models. The functio...

Fig. 13.5 The effect of noise: fP (t) vs. t for representative lattices N 2 f31; 36; 42; 45; 66; 94; 190; 213; 536; 693g from each class, with minimal stochastic perturbations in the domains. All curves are labeled by lattice size. Lattices N 2 f536; 693g were halted at t = 30; 000 before they reached their asymptotic values; all other lattices decayed to fP = 0 and are plotted to t = Tc 1. As ...

butyl-hydroxytoluene (bht) is one of the major synthetic antioxidants with a wide range usage. replacement of artificial antioxidants with natural antioxidants is highly considered. in this research, the antioxidant activity of juniperus excelsa was investigated by using reducing power, dpph radical scavenging and inhibition of lipid peroxidation. also, the amounts of phenolic and flavonoid com...

Euphorbia wallichii a perennial herb growing mainly in Himalayas has been widely used in folk medicines for its medicinal properties. In the present study, the crude methanolic root extract (CME) and its fractions; n-Hexane Fraction (NHF), n-Butanol Fraction (NBF), Chloroform Fraction (CHF), Ethyl acetate Fraction (EAF) and Aqueous Fraction (AQF) of this plant specie were investigated for antio...

We display a number with a surprising continued fraction expansion and show that we may explain that expansion as a specialisation of the continued fraction expansion of a formal series: A series ∑ chX −h has a continued fraction expansion with partial quotients polynomials in X of positive degree (other, perhaps than the 0-th partial quotient). Simple arguments, let alone examples, demonstrate...

Three- to 7-year-olds' ability to calculate with whole-number, fraction, and mixed-number amounts was tested using a nonverbal task in which an amount was displayed and then hidden (J. Huttenlocher, N. C. Jordan, & S. C. Levine, 1994). Next, an amount was added to or subtracted from the hidden amount. The child's task was to determine the hidden amount that resulted from the transformation. Alt...

alzheimer’s disease (ad) is a neurodegenerative disease that was characterized with deposit of beta amyloid (aβ) aggregate in senile plaque. oxidative damage to neurons and loss of cholinergic neurons in forebrain region are observed in this disease. melissa officinalis is a medicinal plant from lamiaceae family, used traditionally in the treatment of cognitive disorders. it has cholinomimetic ...
