Shelf‐Basin Exchange Times Of Arctic Surface Waters Estimated From 228Th/228Ra Disequilibrium, M. Rutgers Van Der Loeff, P. Cai, I. Stimac, D. Bauch, C. Hanfland, T. Roeske, S. Bradley Moran

Graduate School of Oceanography Faculty Publications

The transpolar drift is strongly enriched in 228Ra accumulated on the wide Arctic shelves with subsequent rapid offshore transport. We present new data of Polarstern expeditions to the central Arctic and to the Kara and Laptev seas. Because 226Ra activities in Pacific waters are 30% higher than in Atlantic waters, we correct 226Ra for the Pacific admixture when normalizing 228Ra with 226Ra. The use of 228Ra decay as age marker critically depends on the constancy in space and time of the source activity, a condition that has not yet adequately been tested. While 228 …

Chlorophyll Aalgorithms For Oligotrophic Oceans: A Novel Approach Based On Three-Band Reflectance Difference, Chuanmin Hu, Zhongping Lee, Bryan Franz Jan 2012

Chlorophyll Aalgorithms For Oligotrophic Oceans: A Novel Approach Based On Three-Band Reflectance Difference, Chuanmin Hu, Zhongping Lee, Bryan Franz

Marine Science Faculty Publications

[1] A new empirical algorithm is proposed to estimate surface chlorophyll a (Chl) concentrations in the global ocean for Chl ≤ 0.25 mg m−3(∼78% of the global ocean area). The algorithm is based on a color index (CI), defined as the difference between remote-sensing reflectance (Rrs, sr−1) in the green and a reference formed linearly between Rrsin the blue and red. For low-Chl waters, in situ data showed a tighter (and therefore better) relationship between CI and Chl than between traditional band ratios and Chl, which was further validated using global …

The Short-Sighted Attack On Patent Eligibility Of Healthcare Related Patents, Gregory Dolin Jan 2012

The Short-Sighted Attack On Patent Eligibility Of Healthcare Related Patents, Gregory Dolin

All Faculty Scholarship

On March 20, 2012, the Supreme Court of the United States unanimously decided the case of Mayo Collaborative Svc. v. Prometheus Labs. At issue was a patent, held by Prometheus that taught doctors how to adjust the amount of thiopurine (a drug used for treatment of a variety of autoimmune diseases) administered to a patient. In an opinion by Justice Breyer, the Court held Prometheus’s invention to not be patent eligible and invalidated the patent. Though I believe that the reasoning the Court employed was erroneous and highly problematic (of which more later), the decision could have been viewed as …

My Sister, Our Stories: Exploring The Lived Experience Of School Leavers Through Narrative And Poetics, C. Amelia Davis, Jennifer L. Pepperell

Curriculum, Foundations & Reading: Faculty Publications

The purpose of this study was to explore the educational experiences of two adult female siblings who are both school leavers. Through the use of thematic narrative analysis, sibling narratives and poetic re-presentations, their stories were developed. These stories represent the participants’ experiences of prior schooling and their current commitments to education. While each story conveyed a profound similarity in terms of prior schooling, contrasting narratives were illustrated through description of transitional moments and sibling relationship. The analysis also explored the intersections of race, gender,and social class within educative moments of the life experiences of the participants.

Enrichment Of Minority Dna In Admixes Of Dna Samples:Potential Use In Non-Invasive Prenatal Diagnosis(Nipd), Of Down Syndrome, Tara Miran

Other Faculty of Science and Engineering Theses

Non-invasive prenatal diagnosis (NIPD) is a promising approach that is currently being developed. The principle is that fetal material can be detected in maternal plasma and potentially enable women to pursue reliable and timely prenatal diagnosis, whilst eliminating the risk of miscarriage associated with chorionic villus sampling or amniocentesis. However NIPD research has been restricted up until now for the diagnosis of Down syndrome due to the low concentration of free fetal DNA (ffDNA) in maternal plasma. Various methods have been developed in an attempt to increase the concentration of ffDNA. This study uses COLD-PCR (co-amplification at lower denaturation temperature …

Sea Level Rise And Sustainability Of The Nigerian Coastal Zone, Olusola Olalekan Popoola Jan 2012

Sea Level Rise And Sustainability Of The Nigerian Coastal Zone, Olusola Olalekan Popoola

Other Faculty of Science and Engineering Theses

Globally, sea levels have risen in the last century, and various projections suggest substantial increases in sea level due to climate change in this century. In Nigeria, there are no up-to-date sea level rise (SLR) assessments for the coast. Much of the Nigerian coast is low lying with the consequence that a 1 to 3 metres rise in sea level, which may result from eustatic or climate change, will have a catastrophic effect on the human activities in these regions. This study examines the consequences of continued sea level rise with a focus on erosion and inundation for the Nigerian …

The Effect Of Phytoestrogens On Bone And T Cells Differentiation And Activity, Sahar Saadi Karieb Jan 2012

The Effect Of Phytoestrogens On Bone And T Cells Differentiation And Activity, Sahar Saadi Karieb

Other Faculty of Science and Engineering Theses

The fall in circulating oestrogen (E2) after the menopause leads to an increased rate of bone remodelling, excessive osteoclast activity and a greater fracture risk. Until recently hormone replacement therapy (HRT) was prescribed to post-menopausal women to prevent bone loss, however HRT is associated with an elevated incidence of cardiovascular disease, stroke and cancer. These side-effects led to an interest in naturally occurring compounds with oestrogenic action such as phytoestrogens (PEs), which are non-steroidal-plant derived compounds. Human trials and animal studies suggest a beneficial effect of PEs on bone mass, although their ability to modify osteoclast formation in response to …

Relations Between Impulsivity And Mindfulness In Adolescents With Behavioural, Emotional And Social Difficulties, Jessica Claire Bradford

Other Faculty of Science and Engineering Theses

Impulsivity and the effectiveness of a mindfulness-based intervention were explored in relation to improving behavioural self-regulation in adolescents with behavioural, emotional and social difficulties (BESD). A computerised choice task (CCT) was developed to measure delay discounting (a shift in choice from a larger reward to a smaller reward as the delay to the larger reward increases) in adolescents with BESD and compared it with several additional measures of impulsivity. The degree to which impulsivity and thoughts are related was explored using mindfulness measures. Effects of task type (computer versus sand-timer) and task context (school versus house) were also studied. Results …

Mapping Deep-Sea Features In Uk Waters For Use In Marine Protected Area Network Design, Jaime Selina Davies

Other Faculty of Science and Engineering Theses

With an increase in demand on deep-sea resources comes a need for appropriate and effective management of this ecosystem. The establishment of a representative network of deep-sea Marine Protected Areas offers one tool with which to address the conservation needs of the deep sea. While a number of deep-sea habitats have been identified as vulnerable to anthropogenic activities (e.g. cold-water coral reefs and sponge aggregations), poor knowledge of the distribution of these habitats hinders conservation efforts and network planning, and thus we need habitat maps. With improvements in acoustic data resolution acquired from the deep sea, and the ability to …

Towards The Affect Of Intimacy, Juergen Moritz Jan 2012

Towards The Affect Of Intimacy, Juergen Moritz

Other Faculty of Arts, Humanities and Business Theses

Abstract This thesis explores the trajectory that the developing technological fields of Ambient Intelligence and Persuasive Technologies introduce new intricate relationships beyond fundamental use and availability because they change our abilities to act. Since its classic articulation by Hegel (1927) philosophical explication of the relationship between people and technology states that technology is a mediating factor between people and the world. Associated with this view, which has characterized the resulting phenomenology and philosophy of technology for nearly two decades, is an understanding of technology as a form of alienation. In this dissertation the author shows how this old interpretation of …

Life Expansion: Toward An Artistic, Design-Based Theory Of The Transhuman / Posthuman, Natasha Vita-More

Other Faculty of Arts, Humanities and Business Theses

The thesis’ study of life expansion proposes a framework for artistic, design-based approaches concerned with prolonging human life and sustaining personal identity. To delineate the topic: life expansion means increasing the length of time a person is alive and diversifying the matter in which a person exists. For human life, the length of time is bounded by a single century and its matter is tied to biology. Life expansion is located in the domain of human enhancement, distinctly linked to technological interfaces with biology. The thesis identifies human-computer interaction and the potential of emerging and speculative technologies as seeding the …
