Using the classical technique of condensation singularities, we prove that, for every zero-dimensional, complete separable metric space G, there exists a Suslinian, chainable continuum whose set end points is homeomorphic to G. This answers question posed by R. Adikari and W. Lewis in [Houston J. Math. 45 (2019), no. 2, pp. 609–624].

A micronucleus assay employing fluorescence in situ hybridization (FISH) with a centromeric probe was used on specimens of exfoliated buccal and nasal cells collected from mortuary science students exposed to embalming fluid containing formaldehyde. FISH labeling allowed micronuclei (MN) containing a whole chromosome (centromere-positive, MN+) to be differentiated from those containing only chr...

Rule 609(a)(2) of the Federal Rules Evidence is an outlier. The mandates admission impeaching evidence a witness’s past convictions for crimes dishonesty. It only place in where judges are denied their usual discretion to exclude on grounds that its would be more prejudicial than probative. This Note analyzes three assumptions underlying this unusual Rule: (1) there coherently definable categor...

Bacterial manganese (Mn) oxidation plays an important role in the global biogeochemical cycling of Mn and other compounds, and the diversity and prevalence of Mn oxidizers have been well established. Despite many hypotheses of why these bacteria may oxidize Mn, the physiological reasons remain elusive. Intracellular Mn levels were determined for Pseudomonas putida GB-1 grown in the presence or ...

The objective of this laboratory study was to identify and measure manganese (Mn) fractions in chamber-generated welding fumes (WF) and to evaluate and compare the results from a sequential extraction procedure for Mn fractions with that of an acid digestion procedure for measurement of total, elemental Mn. To prepare Mn-containing particulate matter from representative welding processes, a wel...

In the title complex, [Mn(II)Mn(III) (2)(C(11)H(13)NO(4))(2)(CH(3)CO(2))(4)(H(2)O)(2)]·2CH(3)CN·2H(2)O, there are two Mn(III) and one Mn(II) atoms. The Mn(II) atom lies on an inversion center and the Mn(III)-Mn(II)-Mn(III) angle is therefore 180°, as required by crystallographic symmetry. The Mn(III) and Mn(II) atoms are six-coordinated in a distorted octa-hedral geometry. In the crystal, compl...

Wheat grown in Mn-deficient soil has been widely observed to produce much reduced yields. Breeding for Mn-efficient wheat genotypes adapted to Mn-deficient soils would represent a long-term solution for wheat agronomy. To characterize the physiological basis of Mn efficiency in wheat genotypes would facilitate the breeding programs for producing Mn-efficient wheat. Using a solution culture and ...

In this manuscript, we report that a bacterial multicopper oxidase (MCO266) catalyzes Mn(II) oxidation on the cell surface, resulting in the surface deposition of Mn(III) and Mn(IV) oxides and the gradual formation of bulky oxide aggregates. These aggregates serve as nucleation centers for the formation of Mn oxide micronodules and Mn-rich sediments. A soil-borne Escherichia coli with high Mn(I...

More recently, Wazwaz [An analytic study of Fisher’s equation by using Adomian decomposition method, Appl. Math. Comput. 154 (2004) 609–620] employed the Adomian decomposition method (ADM) to obtain exact solutions to Fisher’s equation and to a nonlinear diffusion equation of the Fisher type. In this paper, He’s homotopy perturbation method is employed for the generalized Fisher’s equation to o...
