Electron momentum spectroscopy experiments and calculations for the production of excited states of He<sup>+</sup> and
No full text The (e,2e) cross-section for transitions to the n = 2 final state of He+ and the 2sσg, final state of [Formula: see text] have been measured, relative to the cross-section for the transitions to the respective ground state ions, using a highly sensitive momentum dispersive multichannel electron momentum spectrometer. The experimental results for He are compared with plane wave impulse approximation (PWIA) cross-section calculations carried out using two previously published GI wavefunctions and also with two cross-section calculations based on explicitly correlated wavefunctions with energy errors of less than 10 nHartree. The H2 results are compared with calculations by J.W. Liu and V.H. Smith Jr. (Phys. Rev. A, 31, 3003 (1985); erratum: Phys. Rev. A, 39, 3703 (1989)). For both He and H2, significant differences are observed between the measured relative cross-sections and those calculated using the PWIA. While the measurements for He differ from previous work, the results for H2 are consistent with some earlier measurements. </jats:p
Phylogenetic lineages in the Botryosphaeriaceae
No full textBotryosphaeria is a species-rich genus with a cosmopolitan distribution, commonly associated with dieback and cankers of woody plants. As many as 18 anamorph genera have been associated with Botryosphaeria, most of which have been reduced to synonymy under Diplodia (conidia mostly ovoid, pigmented, thick-walled), or Fusicoccum (conidia mostly fusoid, hyaline, thin-walled). However, there are numerous conidial anamorphs having morphological characteristics intermediate between Diplodia and Fusicoccum, and there are several records of species outside the Botryosphaeriaceae that have anamorphs apparently typical of Botryosphaeria s.str. Recent studies have also linked Botryosphaeria to species with pigmented, septate ascospores, and Dothiorella anamorphs, or Fusicoccum anamorphs with Dichomera synanamorphs. The aim of this study was to employ DNA sequence data of the 28S rDNA to resolve apparent lineages within the Botryosphaeriaceae. From these data, 12 clades are recognised. Two of these lineages clustered outside the Botryosphaeriaceae, namely Diplodia-like anamorphs occurring on maize, which are best accommodated in Stenocarpella (Diaporthales), as well as an unresolved clade including species of Camarosporium/Microdiplodia. We recognise 10 lineages within the Botryosphaeriaceae, including an unresolved clade (Diplodia/Lasiodiplodia/ Tiarosporella), Botryosphaeria s.str. (Fusicoccum anamorphs), Macrophomina, Neoscytalidium gen. nov., Dothidotthia (Dothiorella anamorphs), Neofusicoccum gen. nov. (Botryosphaeria-like teleomorphs, Diapjomera-like synanamorphs), Pseudofusicoccum gen. nov., Saccharata (Fusicoccum- and Diplodia-like synanamorphs), "Botryosphaeria" quercuum (Diplodia-like anamorph), and Guignardia (Phyllosticta anamorphs). Separate teleomorph and anamorph names are not provided for newly introduced genera, even where both morphs are known. The taxonomy of some clades and isolates (e.g. B. mamane) remains unresolved due to the absence of ex-type cultures
The electron density: experimental determination and theoretical analysis
No full textTwo related lines of research in experimental electron density determination are reported in this thesis. In the first case, the well-proven and popular multipole modeling technique is applied to three high resolution, single-crystal X-ray diffraction data sets. The preliminary part of this thesis (Chapters 2-5) deals with the theoretical aspects of the multipole model, and also some of the theoretical and practical aspects of data collection and reduction. Chapter 6 reports an experimental charge density determination of a nitrogen ylide. Chapter 7 contains details of the treatment of data from a large, pendant-arm macrocyclic complex of nickel, while Chapter 8 reports the characteristics of the experimentally determined charge density for a substituted acetylene molecule which exhibits interesting intramolecular interactions. The charge densities for all three cases are analysed using Bader's Theory of Atoms in Molecules. The latter part of this thesis deals with more novel ways of treating experimental data. Chapter 9 gives a thorough review of the literature on the application of Maximum Entropy techniques to image reconstruction in general and charge density determination in particular, followed in Chapter 10 by an application to diffraction data from the cubic phase of acetylene. The novel approach of removing core scattering from the data is developed and gives improved results. Chapter 11 reviews some aspects of fermion density matrices and their relationship to electron density functions and X-ray scattering, followed in Chapter 12 by results from the density matrix refinement method applied to diffraction data from formamide. Particular emphasis is placed upon basis set effects, idempotency and various N-representable approximations to the experimentally determined density matrix
RISK AND SUSTAINABLE AGRICULTURE: A TARGET-MOTAD ANALYSIS OF THE 92-YEAR "OLD ROTATION"
No full textTarget-MOTAD was used to assess the risks and returns of sustainable cotton crop rotations from Auburn University's 92-year "Old Rotation." Study results analyze rotations of continuous cotton, with and without winter legumes; two years of cotton-winter legumes-corn, with and without nitrogen fertilization; and three years of cotton-winter legumes-corn and rye-soybeans double-cropped. Ten years of observations on deviations from target income were used to identify optimal sustainable rotation(s). Study results suggest that diversification in rotations, as well as in crops, results in the least risk for a given level of target income.Risk and Uncertainty,
Proteins as markers of TSE infection in sheep blood
No full textTransmissible spongiform encephalopathies (TSEs) are a group of fatal infectious
neurodegenerative diseases affecting both humans and agricultural animals. TSE
transmission via blood transfusion has been demonstrated experimentally in rodent,
primate and sheep models. Additionally, in humans, four variant Creutzfeld-Jakob
disease (vCJD) cases have been reported which probably resulted from infected blood
transfusions. Although TSEs can be transmitted via blood transfusion, little is known
about which blood cells are involved in the replication of the TSE agent and how
infectivity is spread throughout the body prior to neuroinvasion. There are no currently
validated diagnostic tests for TSE infection in blood.Detection of PK-resistant PrPSc has been extensively used as a biochemical marker for
TSE infectivity. However, when this project was started it was not known if PKresistant
PrPSc was present in TSE-infected sheep blood in sufficient quantities to
explain the infectivity levels shown by bioassay. Following the development of an
optimised Western blot method, this project has demonstrated that the pattern of protein
detected with novel anti-PrP monoclonal antibodies is very different from the
conventional triple banded pattern of PK-resistant PrPSc. High molecular weight bands
were apparent in phosphotungstic acid (NaPTA) concentrated scrapie-infected and
uninfected blood and may represent a novel form of blood-specific PrP. PK-resistant
PrPSc is not therefore a suitable marker for TSE infection in blood.Other proteins in TSE infected blood were also investigated. Using a proteomics
approach three protein markers, lactate dehydrogenase, elongation factor 1 and annexin
1 had altered expression patterns in scrapie infected blood. These proteins, in addition
to the novel forms of PrP found in blood, may provide new information on the
mechanisms of pathogenesis in scrapie-infected sheep and might prove to be useful
molecular indicators of diagnostic value
Staphylococcus Aureus Bacteremia Among Patients with Health Care-associated Fever
No full textBackground: Although Staphylococcus aureus bacteremia is a common, serious infection, accurately identifying febrile patients with this diagnosis at the time of initial evaluation is difficult. The purpose of this investigation was to define clinical characteristics present at the time of the initial recognition of fever that were associated with the presence of any bloodstream infection and, in particular, with S. aureus bacteremia. Methods: All patients ≥18 years of age with a new episode of health care-associated fever (temperature ≥38°C) and at least one blood culture drawn were eligible for enrollment into this prospective multicenter cohort study. Multivariable analyses were conducted and internally validated scoring systems were developed to categorize the risk of bacteremia. Results: Of 1015 patients enrolled, 181 patients (17.8percent) had clinically significant bacteremia, including 77 patients (7.6percent) with S. aureus bacteremia. Clinical characteristics associated with S. aureus bacteremia were the presence of a hemodialysis graft or shunt (odds ratio [OR] 3.22; 95percent confidence interval [CI], 1.85-5.61), chills (OR 2.38; 95percent CI, 1.43-3.98), and a history of S. aureus infection (OR 2.68; 95percent CI, 1.38-5.20). Peripheral vascular catheters were inversely associated with S. aureus bacteremia (OR 0.42; 95percent CI, 0.26-0.69). Clinical characteristics associated with any bloodstream infection were central venous access, chills, history of S. aureus infection, and hemodialysis access. Conclusions: Among patients with health care-associated fever, the presence of easily recognizable clinical characteristics at the time of obtaining the initial blood cultures can help to identify patients at increased risk for any bloodstream infection, in particular for S. aureus bacteremia. © 2009 Elsevier Inc.

Accurate Compton Profiles For H2 And D2 Including The Effects Of Electron Correlation And Molecular Vibration And Rotation
No full textAccurate isotropic Compton profiles J(q,R) for H2(X 1∑g +) are calculated for 22 internuclear separations from the 126 configuration wavefunctions of Liu. These profiles, supplemented by the united atom and separated atom profiles, are then rigorously averaged over vibration-rotation wavefunctions computed by direct numerical solution of the radial Schrödinger equation using nearly exact potential energy curves including adiabatic and relativistic corrections. These averages are performed for a large number of vibration-rotation states of H2 and the ground vibration-rotation state of D2. It is shown that the effects of averaging Compton profiles over vibration-rotation states are significant and cannot be neglected. The isotope effect is shown to be smaller than the vibration-rotation effect. The peak of the calculated H2 Compton profile for the ground vibration-rotation state is found to be in excellent agreement with the very recent high energy electron impact measurements of Lee. A number of expansion techniques for vibration-rotation averaging, including a new, very simple, and reasonably accurate delta approximation, are presented.
