Superconductive Performance of the Deposited High-β and Tested Medium-β QWR Cavities of the ALPI Linac
No full text8 high-β Nb/Cu superconductive QWR cavities should be
coated for the ALPI upgrade in the framework of the SPES
facility. The QWR cavities should require specific
superconductive performance to be assembled in the ALPI
linac.
RF test cold measurements are used for evaluation of the
coated Nb/Cu quality. Meanwhile, verification of the QWRs
superconductive properties, which are currently used in the
ALPI on-line activity, is also made with RF measurements.
Methodology and results of the sputtered QWRs RF
measurements will be described in this paper. In particular,
cold test results of the ALPI cryostat 7 medium-β QWR
cavities will be mentioned

Establishment and potential spread of the introduced spotted-thighed frog, <i>Litoria cyclorhyncha</i> (<i>Ranoidea cyclorhynchus</i>), in South Australia
No full textData source: Supplementary data, https://doi.org/10.1080/03721426.2018.1444911Litoria cyclorhyncha is a hylid frog native to southwest Western Australia (WA). It was first recorded in South Australia (SA) in 2000 and has established a breeding population in Streaky Bay on the western Eyre Peninsula since at least 2011. L. cyclorhyncha is a relatively large predatory frog that presents a potential threat to fauna and ecosystem processes in SA and eastern Australia. This study examines the invasion history and current and potential future distributions of this frog using historical records, field surveys and species distribution modelling (SDM). The historical records in SA suggest human-assisted dispersal through transport networks. Field surveys throughout the Eyre Peninsula during 2016–2017 detected three native species of frogs but no additional breeding populations of L. cyclorhyncha outside of Streaky Bay. Within Streaky Bay, frog abundance appears to be concentrated around permanent water bodies, but the species is also well established in urban habitats. SDM suggests that suitable environmental conditions exist for L. cyclorhyncha in southern and eastern Australia. This, and the frog’s ability to disperse over long distances, suggests considerable potential for the species to become invasive. As L. cyclorhyncha has potential to significantly impact biodiversity and ecosystems, management strategies are urgently needed

Investigation of a possible material-saving approach of sputtering techniques for radiopharmaceutical target production
No full textMagnetron sputtering (MS) is a relatively new deposition technique, which is being
considered among the cyclotron solid target (CST) manufacturing options now available, aiming at
the medical radioisotopes yield for radiopharmaceutical production. However, the intrinsic high
material losses during the deposition process do not permit its use with extremely expensive target
materials, such as isotopically enriched metals/oxides. In this study, R&D technology for a new
recovering shield is instead proposed to assess the dissipation of target material during the sputtering
processes and, thus, an estimate of the material recovery that may be feasible and the related amount.
The weight-loss analysis method is used to assess the material losses level inside the chamber during
processing. In all tests carried out, a high-purity copper (99.99%) was used as a target material. As a
result of this study, the material distribution for both magnetron and diode sputtering depositions
can be calculated. The feasibility of the ultra-thick coatings growing, devoted to CST production,
is demonstrated
J. D. Brannan letter to Warren G. Harding, January 24, 1921
No full textIn this letter dated January 24, 1921 (the author mistakenly writes 1920), J. D. Brannan at Harvard University Law School to President-elect Warren G. Harding in regards to his choices for cabinet appointments. Brannan recommends Senator Elihu Root for Secretary of State, Charles Evans Hughes for Attorney General, Senator John W. Weeks for Secretary of the Treasury or Secretary of the Navy, and General Leonard Wood for Secretary of War, and includes qualifications for each. After discussing tensions among the government and organized labor leaders, he does not specify an appointment for Secretary of Labor, but includes Herbert Hoover as a qualified candidate.
This letter is part of the Warren G. Harding Papers (MSS 345). This collection includes correspondence, business records, and other materials documenting Harding’s business career as owner and editor-in-chief of The Daily Marion Star, as well as the various stages of his political career. A significant portion of the collection, and what’s available on Ohio Memory, highlights his 1920 presidential campaign, spanning just before publicly announcing his candidacy to handily defeating Ohio Governor James M. Cox in the election. Correspondents include both Ohio and national businessmen, political figures, and ordinary citizens writing with questions, support, congratulatory notes, and campaign advice. Some of the most interesting insights into the tumultuous political climate in the U.S., the extreme factionalism within the Republican Party in Ohio, and Harding’s campaign strategies are described in letters between Harding and his campaign manager, Harry M. Daugherty. Some of the topics addressed include women’s suffrage, Prohibition, the League of Nations, African American representation and issues, and lingering peace negotiations following World War I
Diversification history and hybridisation of Dacrydium (Podocarpaceae) in remote Oceania
No full textLink to a related website: https://espace.curtin.edu.au/bitstream/20.500.11937/18344/2/171226_171226.pdf, Open Access via UnpaywallWe examined evolutionary relationships, hybridisation and genetic diversity in species of Dacrydium (Podocarpaceae) in Remote Oceania, where it is restricted to New Caledonia and Fiji. We used cpDNA sequence (trnL–trnF) data to construct a phylogeny and estimate taxon divergence by using a relaxed molecular clock approach. The phylogeny was verified using allozymes, which were also used to investigate genetic diversity of all species and the hybridisation dynamics of two endangered species, D. guillauminii and D. nidulum. Our results suggested that Dacrydium species in Remote Oceania form a monophyletic group that arose and diversified within the last 20 million years through long-distance dispersal and a range of speciation mechanisms. Whereas we detected no hybridisation between the Fijian species D. nausoriense and D. nidulum, we confirmed hybridisation between D. guillauminii and D. araucarioides in New Caledonia and determined introgression to be assymetric from the widespread D. araucarioides into the rare, restricted-range species D. guillauminii. In addition, D. guillauminii had lower genetic diversity than did the other species of Dacrydium studied, which had genetic diversity similar to that of other gymnosperms. Our results provided evidence for the recent and complex diversification of Dacrydium in Remote Oceania. In addition, low genetic diversity of and introgression from D. araucarioides, are of grave concern for the conservation of D. guillauminii.Gunnar Keppel, Peter Prentis, Ed Biffin, Paul Hodgskiss, Susana Tuisese, Marika V.

The deuteron spin-dependent structure function g(1)(d) and its first moment
No full textAlexakhin VY, Alexandrov Y, Alexeev GD, et al. The deuteron spin-dependent structure function g(1)(d) and its first moment. Phys.Lett. B. 2007;647(1):8-17.We present a measurement of the deuteron spin-dependent structure function g(1)(d) based on the data collected by the COMPASS experiment at CERN during the years 2002-2004. The data provide an accurate evaluation for Gamma(d)(1), the first moment of g(1)(d) (x), and for the matrix element of the singlet axial current, a(0). The results of QCD fits in the next to leading order (NLO) on all g(1) deep inelastic scattering data are also presented. They provide two solutions with the gluon spin distribution function Delta G positive or negative, which describe the data equally well. In both cases, at Q(2) = 3 (GeV/c)(2) the first moment of Delta G(x) is found to be of the order of 0.2-0.3 in absolute value. (c) 2007 Elsevier B.V. All rights reserved
Aspect-ratio dependence of the transition to the ultimate state of turbulent Rayleigh-Bénard convection
No full textWe report on measurements of the ultimate-state transition in turbulent Rayleigh-B\'enard convection obtained in a large facility known as the ``Uboot of G\"ottingen" and using pressurized sulfur hexafluoride as the convecting fluid. We found that the transition occurs over a range of which becomes more narrow as increases, ranging from which is at most weakly dependent on and close to to which varies from about for to about for
