Oligomers of the 40 and 42 residue amyloid-β peptides (Aβ40 and Aβ42) have been implicated in the neuronal damage and impaired cognitive function associated with Alzheimer’s disease. However, little is known about the specific mechanisms by which these misfolded species induce such detrimental effects on cells. In this work, we use single-molecule imaging techniques to examine the initial interactions between Aβ monomers and oligomers and the membranes of live cells. This highly sensitive method enables the visualization of individual Aβ species on the cell surface and characterization of their oligomerization state, all at biologically relevant, nanomolar concentrations. The results indicate …

Associations Between Body Mass Index And Musculoskeletal Pain And Related Symptoms In Different Body Regions Among Workers, Isabel Moreira-Silva, Rute Santos, Sandra Abreu, Jorge Mota

Faculty of Social Sciences - Papers (Archive)

Obesity rates are high among employed adults and have shown a consistent increase over the past few decades. Musculoskeletal disorders related to work are a major cause of disability in working individuals. The objective of this study was to verify the associations between weight status and musculoskeletal pain and related symptoms in different body regions among workers. The sample comprised 203 factory workers. Anthropometric measures were assessed with standardized protocols and body mass index (BMI) was calculated. Participants were classified as nonoverweight (BMI ≤ 24.9 kg/m²) or overweight/obese (BMI ≥ 25 kg/m²). Musculoskeletal pain and related …

A Descriptive Examination Of The Types Of Relationships Formed Between Children With Developmental Disability And Their Closest Peers In Inclusive School Settings, Amanda A. Webster, Mark Carter

Faculty of Social Sciences - Papers (Archive)

Background One of the most commonly cited rationales for inclusive education is to enable the development of quality relationships with typically developing peers. Relatively few researchers have examined the features of the range of relationships that children with developmental disability form in inclusive school settings. Method Interviews were conducted with 25 children with developmental disability, aged 5 and 12 years, their 3 closest peers, and parents and teachers to examine 6 types of relationships. Results Behaviours associated with general friendship and acquaintance were the most commonly reported. Few dyads reported high rates of behaviour associated with special treatment, helping, ignoring, …

Mutual Liking, Enjoyment And Shared Interactions In The Closest Relationships Between Children With Developmental Disabilities And Peers In Inclusive School Settings, Amanda A. Webster, Mark Carter

Faculty of Social Sciences - Papers (Archive)

Typically analysis of the characteristics of friendships is made on the basis of nomination of a friend or best friend, with the assumption that this nomination reflects actual friendship. While it is possible that this assumption may be valid in typically developing children, this may not be the case for relationships for students with developmental disabilities. The relationships of 16 students with developmental disabilities in grades 1 through 6 and their three closest peers were examined to determine if dyads engaged in behaviors associated with defining components of friendship (i.e. shared interaction, mutual enjoyment, mutual liking) from literature on typically …

Coastal Evolution On Volcanic Oceanic Islands: A Complex Interplay Between Volcanism, Erosion, Sedimentation, Sea-Level Change And Biogenic Production, Ricardo S. Ramalho, Rui Quartau, Alan S. Trenhaile, Neil C. Mitchell, Colin D. Woodroffe, Sergio P. Avila

Faculty of Science, Medicine and Health - Papers: part A

The growth and decay of oceanic hotspot volcanoes are intrinsically related to a competition between volcanic construction and erosive destruction, and coastlines are at the forefront of such confrontation. In this paper, we review the several mechanisms that interact and contribute to the development of coastlines on oceanic island volcanoes, and how these processes evolve throughout the islands' lifetime. Volcanic constructional processes dominate during the emergent island and subaerial shield-building stages. During the emergent island stage, surtseyan activity prevails and hydroclastic and pyroclastic structures form; these structures are generally ephemeral because they can be rapidly obliterated by marine erosion. With …

Abrupt Transitions Between Macrobenthic Faunal Assemblages Across Seagrass Bed Margins, R.S.K Barnes, S Hamylton

Faculty of Science, Medicine and Health - Papers: part A

The nature of the transition from one contrasting macrobenthic assemblage to another across interfaces between intertidal seagrass and unvegetated sand was investigated in the subtropical Moreton Bay Marine Park, eastern Australia, via six two-dimensional core lattices. The same pattern of transition was manifested in each lattice. Macrofaunal abundance, species density (both observed and estimated total) and assemblage composition did not vary with distance away from the interface within the 0.75 m wide marginal bands of each habitat type. Neither were there significant differences in assemblage metrics or composition between the marginal and non-edge regions of either habitat. There were, however, …

A Geospatial Assessment Of The Relationship Between Reef Flat Community Calcium Carbonate Production And Wave Energy, S M. Hamylton, A Pescud, J X. Leon, D Callaghan

Faculty of Science, Medicine and Health - Papers: part A

The ability of benthic communities inhabiting coral reefs to produce calcium carbonate underpins the development of reef platforms and associated sedimentary landforms, as well as the fixation of inorganic carbon and buffering of diurnal pH fluctuations in ocean surface waters. Quantification of the relationship between reef flat community calcium carbonate production and wave energy provides an empirical basis for understanding and managing this functionally important process. This study employs geospatial techniques across the reef platform at Lizard Island, Great Barrier Reef, to (1) map the distribution and estimate the total magnitude of reef community carbonate production and (2) empirically ascertain …

A complex of the three (αεθ) core subunits and the β2 sliding clamp is responsible for DNA synthesis by Pol III, the Escherichia coli chromosomal DNA replicase. The 1.7 Å crystal structure of a complex between the PHP domain of α (polymerase) and the C-terminal segment of ε (proofreading exonuclease) subunits shows that ε is attached to α at a site far from the polymerase active site. Both α and ε contain clamp-binding motifs (CBMs) that interact simultaneously with β2 in the polymerization mode of DNA replication by Pol III. Strengthening of both CBMs enables isolation of stable αεθ:β2 complexes. …

Real-Time Single-Molecule Imaging Reveals A Direct Interaction Between Uvrc And Uvrb On Dna Tightropes, Craig D. Hughes, Hong Wang, Harshad Ghodke, Michelle Simons, Atif Towheed, Ye Peng, Bennett Van Houten, Neil M. Kad

Faculty of Science, Medicine and Health - Papers: part A

Nucleotide excision DNA repair is mechanistically conserved across all kingdoms of life. In prokaryotes, this multi-enzyme process requires six proteins: UvrA-D, DNA polymerase I and DNA ligase. To examine how UvrC locates the UvrB-DNA pre-incision complex at a site of damage, we have labeled UvrB and UvrC with different colored quantum dots and quantitatively observed their interactions with DNA tightropes under a variety of solution conditions using oblique angle fluorescence imaging. Alone, UvrC predominantly interacts statically with DNA at low salt. Surprisingly, however, UvrC and UvrB together in solution bind to form the previously unseen UvrBC complex on duplex DNA. …

The Relationship Between Coach Leadership, The Coach-Athlete Relationship, Team Success, And The Positive Developmental Experiences Of Adolescent Soccer Players, Stewart A. Vella, Lindsay G. Oades, Trevor P. Crowe

Faculty of Social Sciences - Papers (Archive)

Background: The goals of participation youth sports are primarily concerned with the facilitation of positive youth development as opposed to outright success. Consequently, there are strong theoretical and empirical links between sports coaching and athlete development. Transformational leadership behaviours, in particular, have been theoretically linked to positive developmental outcomes within a youth sport context, while the coach-athlete relationship is a key tool used by coaches who aim to teach life skills to young athletes. Outright team success has also been shown to correlate with important developmental variables such as a mastery climate and athlete perception of youth sports coaches. Aims: …

Cox proportional hazards models examined the relationship between …

Investigating Synergies Between Literacy, Technology And Classroom Practice, Lisa Kervin, Irina Verenikina, Pauline Jones, Olivia Beath

Faculty of Social Sciences - Papers (Archive)

The ways educators incorporate technologies into their classroom literacy experiences and the implications these present for professional practices have been the focus of discussion for some time. We believe it timely to re-examine these debates in a period of 'digital reform' as we consider the realities teachers report as they use technology as a tool in literacy classrooms. In doing this, we acknowledge the potential of new technologies such as laptops, wireless connectivity, Interactive White Boards and mobile communication devices to reshape pedagogic activity within primary classrooms but aim to capture the reality reported by active practitioners. In this paper …

Comparison Between Sequential And Simultaneous Application Of Activated Carbon With Membrane Bioreactor For Trace Organic Contaminant Removal, Luong N. Nguyen, Faisal I. Hai, Jinguo Kang, Long D. Nghiem, William E. Price, Wenshan Guo, Huu H. Ngo, Kuo-Lun Tung

Faculty of Engineering and Information Sciences - Papers: Part A

The removal efficiency of 22 selected trace organic contaminants by sequential application of granular activated carbon (GAC) and simultaneous application of powdered activated carbon (PAC) with membrane bioreactor (MBR) was compared in this study. Both sequential application of GAC following MBR treatment (MBR–GAC) and simultaneous application of PAC within MBR (PAC–MBR) achieved improved removal (over 95%) of seven hydrophilic and biologically persistent compounds, which were less efficiently removed by MBR-only treatment (negligible to 70%). However, gradual breakthrough of these compounds occurred over an extended operation period. Charged compounds, particularly, fenoprop and diclofenac, demonstrated the fastest breakthrough (complete and 50–70%, in …

Difference Between Far-Infrared Photoconductivity Spectroscopy And Absorption Spectroscopy: Theoretical Evidence Of The Electron Reservoir Mechanism, Tadashi Toyoda, Maho Fujita, Tomohisa Uchida, Nobuyoshi Hiraiwa, Taturo Fukuda, Hideki Koizumi, Chao Zhang

Faculty of Engineering and Information Sciences - Papers: Part A

The intriguing difference between far-infrared photoconductivity spectroscopy and absorption spectroscopy in the measurement of the magnetoplasmon frequency in GaAs quantum wells reported by Holland et al. [Phys. Rev. Lett. 93, 186804 (2004)] remains unexplained to date. This Letter provides a consistent mechanism to solve this puzzle. The mechanism is based on the electron reservoir model for the integer quantum Hall effect in graphene [Phys. Lett. A 376, 616 (2012)]. We predict sharp kinks to appear in the magnetic induction dependence of the magnetoplasmon frequency at very low temperatures such as 14 mK in the same GaAs quantum well sample used …

On The Correlation Between The Effectiveness Of Metamorphic Relations And Dissimilarities Of Test Case Executions, Yuxiang Cao, Zhi Quan Zhou, Tsong Yueh Chen

Faculty of Engineering and Information Sciences - Papers: Part A

Metamorphic testing (MT) is a property-based automated software testing method. It alleviates the oracle problem by testing programs against metamorphic relations (MRs), which are necessary properties among multiple executions of the target program. For a given problem, usually more than one MR can be identified. It is therefore of practical importance for testers to know the nature of good MRs, that is, which MRs are likely to have higher chances of revealing failures. To address this issue we investigate the correlation between the faultdetection effectiveness of MRs and the dissimilarity (distance) of test case execution profiles. Empirical study results reveal …

Clinical Placements In General Practice: Relationships Between Practice Nurses And Tertiary Institutions, Kath Peters, Elizabeth J. Halcomb, Susan Mcinnes

Faculty of Science, Medicine and Health - Papers: part A

As a practice-based discipline a key component of undergraduate nurse education is clinical practice experience. The quality of clinical experiences has a significant impact on the students' ability to function competently post graduation. The relationship between higher education institutions (HEIs) and health service placement providers impacts upon the quality of clinical placements. In Australia, the growth of primary care nursing and the shortage of acute clinical places has prompted HEIs to explore the placement of students in general practice. Given the increasing attention being paid to non-traditional clinical placements, it is timely to explore how universities are establishing relationships and …
