    Studies of local structure of Cm3+ in borosilicate glass using laser and x-ray spectroscopic methods and computational modeling (2000)

    Notes: The local environment of Cm3+ in a borosilicate glass has been probed by a combination of laser spectroscopy, structural modeling, and extended x-ray absorption fine structure (EXAFS) spectroscopy. The Stark splitting for the Cm f–f state transitions is significantly larger than the inhomogeneous line broadening that results from the disordered environment. As a result, the Cm optical spectrum can be fit using an effective operator Hamiltonian to obtain a set of crystal-field parameters. The fitting procedure, which requires the use of a descent-in-symmetry approach, provides a set of parameters for a best fit within tetragonal symmetry. These parameters are then linked to the local environment of Cm through exchange-charge modeling (ECM) of crystal field interactions. Cm in our borosilicate glass is best modeled with six oxygen ions with approximately tetragonal symmetry, and at an average distance of 2.31 (3) Å. The results of crystal-field modeling are supported by EXAFS results. © 2000 American Institute of Physics.

    Notes: The principal factors that limit intensities of short-lived radioactive ion beams produced by the isotope separator on-line technique are time delays due to diffusion of radioactive species from solid or liquid target materials and their effusive-flow transport to the ion source. Although diffusion times can be reduced by proper design of short diffusion length, highly refractory targets, effusive-flow times are more difficult to assess. After diffusion from the target material, the species must travel through the target material and vapor transport system to the ion source. The time required for effusive-flow transport to the ion source depends on the conduction path, chemical reactions between the species and target material and materials of construction, as well as the physical size and geometry of the transport system. We have developed a fast valve (0.1 ms closing time) for introducing gaseous or vapor-state species into the target/vapor transport/ion source/system that permits measurement of effusive-flow times for any gaseous or vaporous species (chemically active or chemically inactive) through any vapor transport system, independent of size and geometry. Characteristic times are determined from the exponential decay of the momentum analyzed ion beam intensity for the species during effusive flow through the vapor transport system under evaluation. This article describes the effusive-flow apparatus and presents characteristic time spectra and characteristic effusive-flow time data for noble gases flowing through a serial-flow target reservoir system. © 2002 American Institute of Physics.

    Notes: A method is introduced for measuring the tunneling of electrons between a specially fabricated scanning probe microscope tip and a surface. The technique is based upon electrostatic force detection of charge as it is transferred to and from a small (10−17 F) electrically isolated metallic dot on the scanning probe tip. The methods for dot fabrication, charging, and discharging are described and electron tunneling to a sample surface is demonstrated. © 2000 American Institute of Physics.

    Notes: Colorectal cancer is a common cancer and common cause of death. The mortality rate from colorectal cancer can be reduced by identification and removal of cancer precursors, adenomas, or by detection of cancer at an earlier stage.Pilot screening programmes have demonstrated decreased colorectal cancer mortality; as a result many countries are developing colorectal cancer screening programmes. The most common modalities being evaluated are faecal occult blood testing, flexible sigmoidoscopy and colonoscopy. Implementation of screening tests has been hampered by cost, invasiveness, availability of resources and patient acceptance. New technologies such at computed tomographic colonography and stool screening for molecular markers of neoplasia are in development as potential minimally invasive tools.This review considers who should be screened, which test to use and how often to screen.

    Molecular mapping determines that Hessian fly resistance gene H9 is located on chromosome 1A of wheat (2005)

    Notes: Hessian fly [Mayetiola destructor (Say)] is one of the major insect pests of wheat (Triticum aestivum L.) worldwide. Hessian fly resistance gene H9 was previously reported to condition resistance to Hessian fly biotype L that is prevalent in many wheat-growing areas of eastern USA and an RAPD marker, OPO051000, linked to H9 in wheat was developed using wheat near-isogenic lines (NILs). However, marker-assisted selection (MAS) with RAPD markers is not always feasible. One of the objectives in this study was to convert an RAPD marker linked to the gene H9 into a sequence characterized amplified region (SCAR) marker to facilitate MAS and to map H9 in the wheat genome. The RAPD fragment from OPO051000 was cloned, sequenced, and converted into a SCAR marker SOPO05909, whose linkage relationship with H9 was subsequently confirmed in two F2 populations segregating for H9. Linkage analysis identified one sequence tagged site (STS) marker, STS-Pm3, and the eight microsatellite markers Xbarc263, Xcfa2153, Xpsp2999, Xgwm136, Xgdm33, Xcnl76, Xcnl117 and Xwmc24 near the H9 locus on the distal region of the short arm of chromosome 1A, contrary to the previously reported location of H9 on chromosome 5A. Locus Xbarc263 was 1.2 cM distal to H9, which itself was 1.7 cM proximal to loci Xcfa2153, Xpsp2999 and Xgwm136. The loci Xgwm136, Xcfa2153 and SOPO05909 were shown to be specific to H9 and not diagnostic to several other Hessian fly resistance genes, and therefore should be useful for pyramiding H9 with other Hessian fly resistance genes in a single genotype.

    Aristotle and Corruptibility (1966)

    Notes: (5) ἆρ' [...] ∈ἰ kaì ⋯γ ∈´νητον (282 a 25) ... πρòς τò ɸθαρτόν, ⋯ϕ' ᾧΘ (283 a 3). Aristotle claims so far to have proved that the eternal is incorruptible and that it is ungenerated. He has still to prove the converse of each of these propositions, namely, that whatever is incorruptible is eternal and that whatever is ungenerated is eternal also. After putting the thesis in question form he gives a further definition of ⋯γ∈´νητος and ἄɸθαρτος in the parenthesis of 282 a 27–30. Unfortunately in both cases he uses the assertoric form of the definiens, although in chapter 11 he had used a modal form in the relevant passages (cf. kυρίως 280 b 32 and 282 a 27); but this confusion does not seem to affect the immediate trend of the argument. He then (282 a 30—b 1) shows that his thesis follows necessarily from the convertibility of ⋯γ∈´νητος and ἄɸθαρτος. The additional premiss that is necessary in order to secure this inference, namely, that that which is both ungenerated and incorruptible is eternal, is clear from the definition of the terms. It is also clear from the convertibility of ɸθαρτóς and γ∈ νητóς, which itself is entailed by the supposed convertibility of their contradictories. This last inference seems too trivial to deserve a mention, but Aristotle devotes 282 b 2–5 to proving it. Then, having demonstrated to his satisfaction that the convertibility of ἄɸθαρτος and ⋯γ∈´νητος necessarily implies the eternity of both the incorruptible and the ungenerated, he adds, for good measure, that if the terms are not convertible the implication is no longer necessary (282 b 5–7).

    Notes: In a discussion-note in Mind (July 1958), Father P. M. Farrell, O.P., gave an account, in what he admitted to be an embarrassingly brief compass, of the Thomist doctrine concerning evil. There is one sentence in this discussion which at first glance appears paradoxical. Father Farrell has been arguing that a universe containing ‘corruptible good’ as well as incorruptible is better than one containing ‘incorruptible good’ only. He continues: ‘If, however, they are to manifest this corruptible good, they must be corruptible and they must sometimes corrupt.’ The final words, despite Father Farrell's italics, strike one as expressing, not a self-evident truth, but a non sequitur. The fact that I am capable of committing murder does not entail that I will at some time commit it. It is not immediately obvious that a similar entailment holds in the case of corruption and corruptibility.

    Notes: Christology seems to fall fairly clearly into two divisions. The first is concerned with the truth of the two propositions: ‘Christ is God’ and ‘Christ is a man’. The second is concerned with the mutual compatibility of these propositions. The first part of Christology tends to confine itself to what is sometimes called ‘positive theology’: that is to say, it is largely given over to examining the Jons revelationis—let us not prejudge currently burning issues by asking what this is—to see what evidence can be found for the truth of these propositions. Clearly, the methods used will be above all those of New Testament exegesis. The second part of Christology will necessarily consist entirely of that speculative theology which is contrasted with positive theology. Even if the earliest speculation on this topic is to be found in the New Testament itself and thus becomes fair game for the exegetes, any attempt to relate the primary truths, ‘Christ is God’ and ‘Christ is a man’, to eachother is a work of reflection, and in the terminology I am using speculative.
