Generalized energy inequalities and higher multifractal moments
No full textWe present a class of generalized energy inequalities and indicate their use in investigating higher multifractal moments, in particular Lq-dimensions of images of measures under Brownian processes, Lq-dimensions of almost self-affine measures, and moments of random cascade measure
R.J. Sommers
No full textThe single-spaced paragraph on the “About the Author” page of R.J. Sommers’ latest novel says she lives in a one-story house on the edge of a city. It says she is renowned for writing relatable characters and compelling relationships. It says nothing about her own friends.
Gazing from a photo at the top of the page, R.J. Sommers appears to point a camera toward her readers..
Tracking aggregation and fibrillation of globular proteins using terahertz and far-infrared spectroscopies
No full textPartially unfolded proteins can self-assemble to form insoluble protein fibrils with diameters in the nanometer scale. These are of particular interest in healthcare because of their presence in diseases such as Alzheimer's disease and type-II diabetes. Tracking the formation of protein fibrils has far-reaching benefits for research into treatment of these diseases. Current optical techniques that track fibrillation either limit samples to their aqueous form or are slow to conduct. We present in this work terahertz and far-infrared (FIR) spectroscopic analyses of fibrils made from three globular proteins. We track the fibrillation process over an extended period to show that mature fibrils have distinct absorbance properties that are not solely caused by scattering. Results also show that FIR spectroscopy can provide information about fibril structures that is otherwise missed by optical techniques.Gretel M. Png, Robert J. Falconer, Derek Abbot
Generalized dimensions of images of measures under Gaussian processes
No full text26 pagesWe show that for certain Gaussian random processes and fields X:RN→Rd, Dq(μx) = min {d, 1/α Dq (μ)} a.s., for an index α which depends on Hölder properties and strong local nondeterminism of X, where q>1, where Dq denotes generalized q-dimension μX is the image of the measure μ under X. In particular this holds for index-α fractional Brownian motion, for fractional Riesz–Bessel motions and for certain infinity scale fractional Brownian motions.Peer reviewe
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)
Report on industrial attachment with R.J. Crocker Consultants Pte Ltd
No full textThis report documents the undertaking of the author’s six months of industrial attachment. It was the industrial attachment that gave him the opportunity to discover the innovative skills and expertise from his fellow colleagues working the organization. Throughout the attachment, the author had learnt a great deal from various trained and experienced engineers. He had been exposed to a variety of training namely (1) reinforcement concrete design, (2) steel and connection design, (3) modelling structures for design and analysis using software, (4) visual inspections for buildings, (5) preparing tender documents, (6) drawing, presentation and attending and (7) handling online submissions for building inspections, structural plans, design calculations, etc. Furthermore, by attending project meetings, preparing materials for presentations, tendering documents and drawings to privatized companies and public sectors all bestowed the author a concrete understanding of the type and quality of work required of and produced by a qualified engineer. Without the industrial attachment, all these practical skills and knowledge might not have been attainable by learning in the university alone. It was overall a fruitful experience
Applications of isothermal titration calorimetry - the research and technical developments from 2011 to 2015
No full textIsothermal titration calorimetry is a widely used biophysical technique for studying the formation or dissociation of molecular complexes. Over the last 5years, much work has been published on the interpretation of isothermal titration calorimetry (ITC) data for single binding and multiple binding sites. As over 80% of ITC papers are on macromolecules of biological origin, this interpretation is challenging. Some researchers have attempted to link the thermodynamics constants to events at the molecular level. This review highlights work carried out using binding sites characterized using x-ray crystallography techniques that allow speculation about individual bond formation and the displacement of individual water molecules during ligand binding and link these events to the thermodynamic constants for binding. The review also considers research conducted with synthetic binding partners where specific binding events like anion-π and π-π interactions were studied. The revival of assays that enable both thermodynamic and kinetic information to be collected from ITC data is highlighted. Lastly, published criticism of ITC research from a physical chemistry perspective is appraised and practical advice provided for researchers unfamiliar with thermodynamics and its interpretation
Information Circular 12. Selected Bibliography of Cuyuna Range Geology, Mining and Metallurgy
No full textThis work is an extension of a bibliography prepared by the author as part of a final report submitted to the U.S. Bureau of Mines for grant # G026/t002 entitled "Manganese-bearing ores of the Cuyuna iron range, east-central Minnesota, Phase 1". This bibliography, though directed primarily towards the geologic and mining literature of the Cuyuna range, does include the major works on the metallurgical aspects of the Cuyuna ores. For historical interest the very earliest publications are included. This list of abbreviations given on pages 2-4 are consistent with those from the "Bibliography and Index of Geology".Beltrame, R.J.. (1977). Information Circular 12.

The Late Fifteenth-Century Utrecht Chronicle of the Teutonic Order: Manuscripts, Sources, and Authorship
No full textBy studying the Utrecht Chronicle of the Teutonic Order, also known as the ‘Jüngere Hochmeisterchronik’, I aimed to examine the circulation of (historical) knowledge within the Teutonic Order at the end of the fifteenth century. Only decades earlier, the order suffered major defeats in Prussia and its former heathen enemies had become Christians. It has been the underlying aim of this study to gain an understanding of the introduction of the order’s tradition of history writing to the Dutch Low Countries, far removed from the traditional production centres in Prussia and Livonia, as well as the effects this change of location, and accompanying change of perspective had on the content and purpose of such historical production within the order. In this dissertation, I have been able to establish that the chronicle was written in Utrecht, in various phases from 1480 to 1491 and possibly the mid-1490s, by the Utrecht land commander Johan van Drongelen and his personal secretary. The material product of their collaboration is a manuscript kept in Vienna, which can now be classified as an author’s copy. I have also shown in detail how the text was constructed, and that the author(s) managed to collect a wide selection of sources – including from locations hundreds of kilometres away from the city of Utrecht. We have therefore come much closer to understanding the specific circumstances under which the chronicle was written, as well as the preconditions of that environment which made it possible to undertake such an ambitious project
