Platinum-cored ferritins were synthesized as electrocatalysts by electrochemical biomineralization of immobilized apoferritin with platinum. The platinum cored ferritin was fabricated by exposing the immobilized apoferritin to platinum ions at a reduction potential. On the platinum-cored ferritin, oxygen is reduced to water with four protons and four electrons generated from the anode. The ferr...

During the past decade correlated α-decay chains have been observed in several independent experiments using Ca-induced fusion-evaporation reactions on actinide targets [1]. These are interpreted to originate from the production of isotopes with proton numbers Z = 113-118. In a recent experiment at the GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt, Germany, using the reaction ...

Given a graph G = (V,E) and an integer k ∈ N, we study k-Vertex Separator (resp. k-Edge Separator), where the goal is to remove the minimum number of vertices (resp. edges) such that each connected component in the resulting graph has at most k vertices. Our primary focus is on the case where k is either a constant or a slowly growing function of n (e.g. O(log n) or n). Our problems can be inte...

A model was developed to estimate total suspended solids (TSS) removal in the Stormceptor, an oil/sediment separator. The model was based on a commonly used continuous simulation model (USEPA SWMM) for hydrological processes. The suspended solids’ loading was estimated using build-up and wash-off equations. The solids were assumed to be distributed into five particle sizes for settling calculat...

Air-core magnets are commonly used components of high energy physics and nuclear physics accelerators for guiding charged particle beams. The design of air-core magnet is dominated by the precise placement of current carrying coils. The resulting magnetic field can be obtained by direct application of the Biot-Savart law. A new DA and TM based approach was implemented to describe the current ca...

[1] Plasma, electric, and magnetic field data on the Polar spacecraft have been analyzed for the 29 May 1996 magnetopause traversal searching for evidence of in situ reconnection and traversal of the separator. In this paper we confine our analysis to model-free observations and intrasensor coherence of detection of the environs of the separator. (1) We illustrate the first documented penetrati...

We investigate relations between different width parameters of graphs, in particular balanced separator number, treewidth, and cycle rank. Our main result states that a graph with balanced separator number k has treewidth at least k but cycle rank at most k · ( 1 + log nk ) , thus refining the previously known bounds, as stated by Robertson and Seymour (1986) and by Bodlaender et al. (1995). Fu...

Dried and ground leaves of Crithmum maritimum were used as a matrix for supercritical extraction of volatile oil with CO2. Operative conditions were: extractor, 90 bar and 50 °C for 240 min; first separator, 90 bar and –10°C; second separator, 15 bar and 15 °C. GC/MS analysis of the leaves volatile oil revealed that it mainly consisted of: para-cymene, βphellandrene, γ-terpinene, thymol methyl ...

Short lived Ra isotopes have been produced at the TRIμP facility in inverse kinematics via the fusion-evaporation reaction Pb+C at 8 MeV/u. Isotopes are separated from other reaction products online using the TRIμP magnetic separator. The energetic radium (Ra) isotopes at the exit of the separator were converted into low energy ions with a thermal ionizer. Ra isotopes have been identified by ob...

In this note we develop some of the properties of separators of points in a multiprojective space. In particular, we prove multigraded analogs of results of Geramita, Maroscia, and Roberts relating the Hilbert function of X and X \ {P} via the degree of a separator, and Abrescia, Bazzotti, and Marino relating the degree of a separator to shifts in the minimal multigraded free resolution of the ...
