This study was conducted to answer two research questions: (1) what is the spatial variability of the leaf optical properties between 400-1600 nm (hemispherical-directional reflectance, transmittance, absorption) within young Norway spruce crowns, and (2) how to design a suitable physically-based approach retrieving the total chlorophyll content of a complex coniferous canopy from very high spatial resolution (0.4 m) hyperspectral data? It was proved that sun-exposed needles of current age-class statistically differ (alpha-level = 0.01) from rest of the needles in reflectance between 510-760 nm. Last four age-classes of sun-exposed needles were also found to be significantly different from almost all …

This paper addresses the main goals and objectives of the Hyperspectral Imaging Network (HYPER-I-NET), a recently started Marie Curie Research Training Network. The project is designed to build an interdisciplinary research community focusing on hyperspectral imaging activities. The core strategy of the network is to create a powerful interdisciplinary synergy between different domains of expertise closely related to hyperspectral imaging activities in Europe, ranging from sensor design and flight operation to data collection, processing, interpretation, and dissemination. Our main goals in this paper are to present the project to the Geoscience and Remote Sensing community and to provide an overview …


Shell Artefact Production At 32,000-28,000 Bp In Island Southeast Asia: Thinking Across Media?, Katherine Szabo, Adam Brumm, Peter Bellwood Jan 2007

The evolution of anatomical and behavioural modernity in Homo sapiens has been one of the key focus areas in both archaeology and palaeoanthropology since their inception. Traditionally, interpretations have drawn mainly on evidence from the many large and well-known sites in Europe, but archaeological research in Africa and the Levant is increasingly altering and elaborating upon our understanding of later human evolution. Despite the presence of a number of important early modern human and other hominin sites in Southeast Asia, evidence from this region has not contributed to the global picture in any significant way. Indeed, the acknowledged simplicity of …


Maintaining Quality Feedback In The Face Of Increasing Student Numbers, Simon B. Bedford Jan 2007

Maintaining Quality Feedback In The Face Of Increasing Student Numbers, Simon B. Bedford

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

This study sought to use new and more effective methods of formative feedback to students within the context of Chemistry teaching in order to facilitate student learning. Emphasis was placed on the use of student directed assessment, and in particular, the use of student self- and peer-assessment. During semester 2 of the 2005-06 academic year, a cohort of some 100 Chemistry students and 33 Natural Sciences students attended a series of problem-based workshops designed to test self- and peer- assessment methods.

The aim of this study was to measure the effects of 12 weeks of conjugated linoleic acid (CLA) supplementation on body composition, RER, RMR, blood lipid profiles, insulin sensitivity and appetite in exercising, normal-weight persons. In this double-blind, randomised, controlled trial, sixty-two non-obese subjects (twenty-five men, thirty-seven women) received either 3.9 g/d CLA or 3.9 g high-oleic acid sunflower oil for 12 weeks. Prior to and after 12 weeks of supplementation, oral glucose tolerance, blood lipid concentrations, body composition (dual-energy X-ray absorptiometry and computerised tomography scans), RMR, resting and exercising RER and appetite were measured. There were no significant effects …


A Study Into The Use Of Computer Aided Assessment To Enhance Formative Assessment During The Early Stages Of Undergraduate Chemistry Courses, Simon B. Bedford, Gareth J. Price Jan 2007

A Virtual Learning Environment (WebCT and latter Moodle) was used to provide students with instant, meaningful feedback on their study of chemistry units during their first semester at University. Short multiple choice questions (MCQ's) were written covering each segment of material delivered in lectures and made available to students over the University computer intranet to allow "24/7" access. The most important aspect of the work was the feedback offered to students within the questions, which was written by undergraduate students to ensure its usefulness. The vast majority of the cohort used the MCQ's, most to gain formative feedback and some …


How Much Do Kangaroos Of Differing Age And Size Eat Relative To Domestic Stock?: Implications For The Arid Rangelands, Terence Dawson, Adam Munn Jan 2007

How Much Do Kangaroos Of Differing Age And Size Eat Relative To Domestic Stock?: Implications For The Arid Rangelands, Terence Dawson, Adam Munn

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

Over more than a century there has been debate about the interactions of kangaroos and introduced domestic stock, especially sheep, in the semi-arid and arid rangelands. The potential for competition between the species is still controversial, with pastoralists generally assuming that exploitative competition is a continuing feature of the rangelands, with competition by kangaroos leading to reduced stock production and carrying capacity. The current scientific consensus is that in the arid rangelands such competition is not common and occurs largely during dry periods when pasture is sparse. Competition is probably most persistent in more degraded environments. There is still debate …


Polymorphisms Of Cx3cr1 And Cxcr6 Receptors In Relation To Haart Therapy Of Hiv Type 1 Patients, Andreas M. Passam, George Sourvinos, Elias Krambovitis, Spyridon Miyakis, Nikolaos G. Stavrianeas, Ioannis Zagoreos, Demetrios A. Spandidos Jan 2007

The chemokine polymorphisms CXCR6-3E/K, In1.1T/C, H7 haplotype, CX3CR1-V249I, and CX3CR1-T280M have been shown to affect the course of HIV infection. We studied their influence on immunologic and virologic response to HAART in a group of 143 HIV-1 patients. We performed Kaplan-Meier analysis using the following end-point criteria: (1) time from HAART initiation to undetectable viral load (VL < 50 copies/ml), (2) maximum duration of viral suppression, (3) time from HAART administration until CD4 elevation above 200 cells/ul for patients with baseline CD4 below 200 cells/ul and above 500 cells/ul for patients with baseline CD4 between 200 and 500 cells/ul, respectively, and (4) time from HAART initiation until CD4 reduction below baseline values. Our results revealed an improved immunologic response to HAART in patients with the CX3CR1-249I or CX3CR1-280M allele. On the contrary, patients with initial VL suppression due to HAART showed a faster virologic failure in the presence of the CXCR6-3K allele. The In1.1T/C polymorphism and H7 haplotype did not reveal any specific effect on HAART response.
