Structure and binding energies of monohydrated Cd and Cd2+
No full textHigh-level ab initio calculations have been performed on the neutral Cd .H2O complex, and the dication, Cd2+.H2O. Effective core potentials (ECPs) are employed for cadmium, augmented with a large, flexible polarization space, which also includes diffuse functions. The calculated double ionization energy for Cd is within 0.03 eV of the experimental value, suggesting that the basis set is able to describe both Cd and Cd2+ well. For both complexes, three main structures were considered: C-2 nu with the cadmium atom interacting with the oxygen atom of H2O; C-2 nu with the cadmium atom interacting with both hydrogens of H2O; and planar CS where the cadmium interacts with only one of the hydrogen atoms of H2O. The global minimum for Cd .H2O is found to be the trans CS structure, whereas for Cd2+.H2O, the charge-dipole interaction leads to the CU geometry, with the cadmium interacting with the oxygen atom of H2O being the lowest in energy. Our best values for the binding energies, De, are: Cd .H2O, 134 cm(-1) (0.4 kcal mol(-1)); Cd2+.H2O, 78 kcal mol(-1), employing the CCSD(T) method. We conclude that the Cd2+.H2O complex is stable with respect to charge transfer and should be observable; after correction for zero-point vibrational energy, the stability of Cd .H2O is less certain from the results of the calculations
Physically inspired interactive music machines: making contemporary composition accessible?
No full textMuch of what we might call "high-art music" occupies the difficult end of listening for contemporary audiences. Concepts such as pitch, meter and even musical instruments often have little to do with such music, where all sound is typically considered as possessing musical potential. As a result, such music can be challenging to educationalists, for students have few familiar pointers in discovering and understanding the gestures, relationships and structures in these works. This paper describes on-going projects at the University of Hertfordshire that adopt an approach of mapping interactions within visual spaces onto musical sound. These provide a causal explanation for the patterns and sequences heard, whilst incorporating web interoperability thus enabling potential for distance learning applications. While so far these have mainly driven pitch-based events using MIDI or audio files, it is hoped to extend the ideas using appropriate technology into fully developed composition tools, aiding the teaching of both appreciation/analysis and composition of contemporary music
Cd-regulated gene expression in Datura innoxia
No full textThe effects of Cd on the expression of specific proteins and transcripts have been examined in Cd-resistant (Cd300) and Cd-sensitive cultures of Datura innoxia. 2D PAGE analysis of the soluble fraction of D. innoxia protein proved problematic. Proteins precipitated on the surface of lEF gels. This was overcome by loading the samples in the gel mixture prior to polymerisation. Polymerisation of gels containing protein extracted from Cd-exposed cells only occurred when PCs, Cd and other components were resolved from the proteins eluting in the void volume following fractionation by gel filtration chromatography (Sephadex G50). Two peptides, designated Cd-1 and Cd-2, were detected in the Cd300 cells only after exposure to Cd. Cd-1 and Cd-2 were also both detected following exposure of the Cd300 cells to 125 piM Cu or Zn, or HS (42 ˚C 4 h). Neither Cd-1 nor Cd-2 were observed in protein extracts from WDI cells exposed to 125 μM Cd for 8 h. Both Cd-1 and Cd-2 proved refractory to Edman degradation while the N-terminal 30 amino acids of a third, constitutively expressed protein, designated Protein-3, were determined using equivalent procedures. This protein showed sequence similarity to PR proteins. Although cleavage of Cd-1 and Cd-2 generated polypeptides which were not terminally blocked, no sequence information was obtained from these polypeptides, even following purification using standard techniques. Oligonucleotide primers designed from the amino acid sequence of Protein-3 were successfully used to amplify, from cDNA, a fragment which was cloned, sequenced and shown to encode the characterised protein. A longer fragment was also amplified from cDNA by RACE PGR. However, this product was not cloned. In order to identify cDNA sequences encoding Cd-1 and Cd-2 an expression cDNA library was prepared and antibodies raised against the two peptides. However, no antigenicity could be detected when antisera raised against Cd-1 or Cd-2, or the purified IgG fractions, were used to probe western blots. The XZAP cDNA (Cd-exposed) library was "differentially screened" in order to isolate clones corresponding to Cd-induced genes. This led to the isolation of two Cd- induced clones designated Cd-6 (949 bp) and Cd-8 (659 bp). Both clones hybridised to transcripts of approximately 900 bp. Transcripts were also detected in RNA samples extracted from D. innoxia exposed to HS (42 ˚C 4 h), however no transcripts were detected in WDI cells exposed to Cd. Southern blots revealed hybridisation to multiple bands, possibly indicating the presence of a gene family. A motif, C-C-X-C-C, found in the a-domain of metallothioneins, was identified in Cd-6. This may represent a putative metal binding site in Cd-6
Author Co-Citation Analysis (ACA): a powerful tool for representing implicit knowledge of scholar knowledge workers
No full textIn the last decade, knowledge has emerged as one of the most important and valuable organizational assets. Gradually this importance caused to emergence of new discipline entitled ―knowledge management‖. However one of the major challenges of knowledge management is conversion implicit or tacit knowledge to explicit knowledge. Thus Making knowledge visible so that it can be better accessed, discussed, valued or generally managed is a long-standing objective in knowledge management. Accordingly in this paper author co- citation analysis (ACA) will be proposed as an efficient technique of knowledge visualization in academia (Scholar knowledge workers)
Portfolio of recorded performances and exegesis: Messiaen’s musical language for the jazz pianist - an exploration through performance.
No full textMoving beyond Gunther Schuller’s Third Stream amalgamation of classical and jazz, this study explores whether the musical language of Olivier Messiaen can make a valid contribution to jazz piano performance. Initially, my project sought to answer such questions as: What elements of the musical language of Messiaen already exist in the jazz vocabulary? Am I able to extend this further? What are the timbral structures and pianistic effects within Messiaen’s musical language? What will be the most effective application of Messiaen’s musical language to jazz piano performance? Endeavouring to answer the final question led me to consider such aspects as whether the project should be limited to quoting Messiaen motifs, arranging Messiaen melodies, replacing jazz harmonic structures on standards with examples from Messiaen’s musical language or whether it would be better to approach the research conceptually. The work of Hubert Nuss provided encouraging reassurance that this was not an impossible task. In order to articulate this conception, the initial challenge was to decide how the classical and jazz worlds might meet in a ‘Messiaen’ technique. The approach adopted was similar to that used for undergraduate jazz study, namely, immersion in the piano scores and recordings of Messiaen’s music as well as by live performances. This was followed by the development and assessment of a contrived approach when specific techniques, such as tonal colourings or harmonic structures, were developed through prepared exercises and consciously included in my performance. It was then compared with an intuitive approach when no such precise parameters were established. This submission consists of CD recordings of two public recitals and an exegesis. It documents the development of this Messiaen technique and discusses its application in my performances. It also demonstrates the ways that Messiaen’s musical language can be used within jazz piano performance to provide a colour that distinguishes jazz piano performance in a competitive field.Thesis (M.Mus.) -- University of Adelaide, Elder Conservatorium of Music, 201
Computer simulations of the interactions of the (012) and (001) surfaces of jarosite with Al, Cd, Cu2+ and Zn
No full textJarosite is an important mineral on Earth, and possibly on Mars, where it controls the mobility of iron, sulfate and potentially toxic metals. Atomistic simulations have been used to study the incorporation of Al3+, and the M2+ impurities Cd, Cu and Zn, in the (0 1 2) and (0 0 1) surfaces of jarosite. The calculations show that the incorporation of Al on an Fe site is favorable on all surfaces in which terminal Fe ions are exposed, and especially on the (0 0 1) [Fe3(OH)3]6+ surface. Incorporation of Cd, Cu or Zn on a K site balanced by a K vacancy is predicted to stabilize the surfaces, but calculated endothermic solution energies and the high degree of distortion of the surfaces following incorporation suggest that these substitutions will be limited. The calculations also suggest that incorporation of Cd, Cu and Zn on an Fe site balanced by an OH vacancy, or by coupled substitution on both K and Fe sites, is unfavorable, although this might be compensated for by growth of a new layer of jarosite or goethite, as predicted for bulk jarosite. The results of the simulations show that surface structure will exert an influence on uptake of impurities in the order Cu > Cd > Zn, with the most favorable surfaces for incorporation being (0 1 2) [KFe(OH)4]0 and (0 0 1) [Fe3(OH)3]6+
