Temporal and vertical IP25 concentrations were measured in sea ice from a second location in the Canadian Arctic, Resolute Bay, Nunavut. Sea ice samples were collected as part of the Arctic ICE project in collaboration with scientists of the University of Manitoba from April to June 2011. Comparisons were made between other established lipid biomarkers of diatom origin and general organic production, along with previously established temporal and vertical distributions in sea ice collected from the Amundsen Gulf, …

The Characterisation Of The Freezing Damage Response During Flowering In European And Middle Eastern Wheat Cultivars (Triticum Aestivum L), Mohammed Hamdan Edan Al-Issawi

Other Faculty of Science and Engineering Theses

Wheat (Triticum aestivum L.) is occasionally exposed to low temperature during flowering and huge economic losses can occur especially in some key production countries such as Australia. Although it is generally predicted that there will be a rise in global temperature there are still predicted to be risks associated with low temperature for temperate crops. Post head emergence frost damage remains a major constraint to increasing wheat production. Five Iraqi varieties (Abu-Ghariab, Fatah, Sham6, IPA95 and IPA99) were screened for their frost hardiness (LT50). Abu-Ghariab was chosen for further investigations along with the European cv. Claire because the acclimated frost …

Molecular Characterisation Of Clinical And Environmental Isolates Of Vibrio Parahaemolyticus, Hadaf Mahdi Kadhim

Other Faculty of Science and Engineering Theses

The halophilic bacterium Vibrio parahaemolyticus is widely distributed as a natural inhabitant of marine and estuarine environments. Some strains cause gastroenteritis in humans. Clinical isolates are thought to possess virulence factors that are absent from the majority of environmental isolates. Studies were undertaken to differentiate clinical (virulent) and environmental (mainly avirulent) forms of Vibrio parahaemolyticus. Initially, identification and confirmation of a total of 55 V. parahaemolyticus isolates (23 clinical and 32 environmental) was carried out by using selective media, biochemical and nutritional tests. Identity was confirmed by specific polymerase chain reaction (PCR) targeting the toxR gene. In an attempt to …

Visual Images As A Motivational Bridge To Pro-Environmental Behaviour: A Cognitive Approach, Christine Boomsma

Other Faculty of Science and Engineering Theses

Communicating climate change and other long-term environmental issues to the wider public is a challenging process involving many barriers to action. Visualisations have the ability to overcome these barriers. Furthermore, the benefits of visual images over verbal information have been supported. However, there is a lack of research on how visual images can motivate behaviour. Based on Elaborated Intrusion theory, it is proposed that visual images can be internalised as mental images which can act as a ‘motivational bridge’ for pro-environmental behaviour. Six studies exposed participants to visual pro-environmental messages. Throughout all studies images were internalised as mental images, associated …

The Effect Of Hyperbaric Oxygen Therapy On Osteoclast And Osteoblast Function, Hadil Al-Hadi

Other Faculty of Science and Engineering Theses

Bone remodelling, the process by which the skeleton adapts to environmental changes, is dependent on the actions of osteoclasts that resorb bone and osteoblasts which make new bone matrix. Aberrant remodelling underpins bone loss in several debilitating skeletal diseases such as osteoporosis, metastatic breast cancer and multiple myeloma. Changes in remodelling activity can also arise as a consequence of therapeutic intervention for instance intravenous bisphosphonate treatment is associated with osteochemonecrosis of the jaw and localised osteoradionecrosis is a common side effect of radiotherapy. Hyperbaric oxygen is often used as an adjunctive therapy in the treatment of these disorders. HBO involves …

The Effect Of Environmental Factors On The Physiology, Yield And Oil Composition Of Safflower (Carthamus Tinctorius L.), Shiren Jalal Mohamed

Other Faculty of Science and Engineering Theses

This study investigated the effects of drought, nitrogen fertilizer and elevated CO2 and its interaction with nitrogen fertilizer on the physiology, growth, and production of the oil crop safflower (Carthamus tinctorius L.) in a semi-controlled glasshouse environment. Three levels of water stress were imposed: rosette (mid-season drought), stem elongation (terminal drought) and rosette to maturity (mid-season + terminal drought). Results indicated that all drought treatments imposed reduced stomatal conductance, but after the relief of mid-season drought plants recovered and as a result there were no significant differences from control in terms of yield components (branch and capital number) and seed …

Motivated Reasoning And Response Bias: A Signal Detection Approach, Dries Trippas

Other Faculty of Science and Engineering Theses

The aim of this dissertation was to address a theoretical debate on belief bias. Belief bias is the tendency for people to be influenced by their prior beliefs when engaged in deductive reasoning. Deduction is the act of drawing necessary conclusions from premises which are meant to be assumed as true. Given that the logical validity of an argument is independent of its content, being influenced by your prior beliefs in such content is considered a bias. Traditional theories posit there are two belief bias components. Motivated reasoning is the tendency to reason better for arguments with unbelievable conclusions relative …

The main driver of the study was to appreciate the cause of this disparity. The study first reviewed a wide body of literature on issues involving the use of technology which included …

Public Attitudes Towards Crime And Punishment In Greece And The Factors Underlying Their Construction, Magdalini Pipini

Other Faculty of Arts, Humanities and Business Theses

Public opinion regarding crime-related issues is a challenging matter for researchers and politicians alike. An ill-informed public with regards to crime, punishment and other aspects of the criminal justice system leads to discontent and demands for harsher policies to strengthen public safety. Politicians harness public opinion to secure votes, and this can result in punitive policies that are founded on erroneous beliefs. The objective of this study is to look more deeply into people’s attitudes towards crime and punishment, and to consider why Greek people hold the views that they do and how these views are constructed. A multi-method approach …

User-Based Filter Utilization For Multicarrier Schemes, Zekeriyya Esat Ankarali

USF Tampa Graduate Theses and Dissertations

Multicarrier modulation is a transmission technique that is quite convenient for high data rates in wireless communication. Information symbols are partitioned and parallelly sent over multiple narrowband subchannels. Pulse shaping filters are critically important in multicarrier

modulation for determining the characteristics of signal in time and frequency domains. In this thesis, we propose a new pulse shaping approach for multicarrier schemes to increase spectral efficiency in multi-user scenarios. Conventionally, the time-frequency lattice and the prototype filter are designed considering the worst-case of time-varying multipath channel. However, this approach ignores to make use of multi-user diversity and leads to excessive spacings …

Cognitive Processes Developed By Students When Solving Mathematical Problems Within Technological Environments, Fernando Barrera-Mora, Aarón Reyes-Rodríguez

The Mathematics Enthusiast

In this paper we document and discuss how the use of digital technologies in problem solving activities can help students to develop mathematical competences; particularly, we analyze the characteristics of reasoning that students develop as a result of using Cabri Geometry software in problem solving. We argue that the dynamical nature of representations constructed with Cabri, and the availability of measure tools integrated to it are important elements that enhance students’ ability to think mathematically and foster the implementation of several heuristic strategies in problem solving processes.
