Magneto–Optical Kerr Effect Microscopy Investigation on Permalloy Nanostructures
No full textThis thesis focuses on the investigation of magnetic domains in ultrasmall permalloy (Ni80Fe20) structures down to nanometre size. Magnetic domains and domain walls in nano objects are often observed using a very high resolution and high power microscope such as magnetic soft x-ray microscope, magnetic force microscopy imaging and photoemission electron microscopy. A reason for this is because the Kerr signal in nanostructures is very weak. However the results from this thesis demonstrate that magnetic domains in permalloy magnetic nanostructures can still be observed with very good contrast using a Magneto-optical Kerr effect (MOKE) microscope. The constructed Kerr microscope is a home-build wide field microscope and is able to produce magnetic domains image of permalloy nanowire as small as 245 nm, although the resolution limit of the microscope is 505 nm. For the first time, a magnetic domain in nanowire with width of 245 nm is observed using a wide-field microscope. The combination of hysteresis loops and magnetic domains observations for studying a magnetic sample provides a three-dimensional understanding of the magnetic characteristic of the sample. This is crucial in investigating nano samples as the theoretical arguments with the experimental results are always constrained by the experimental part. Three kinds of nanostructure sample were observed using the Kerr microscope; a cross nanowire, zigzag nanowire and a nanowire with notch and a nucleation pad at one end. It was found that a cross nanowire can form magnetic domains upon reversal and the junction forms a magnetisation vortex. Findings from zigzag nanowire demonstrate a complex, multiple magnetic domains formation upon magnetisation reversal. A weak domain wall pinning effect was observed in the nanowire, causing a multiple domains formation in the nanowire upon reversal. It can be confirmed that this effect was caused by the high coercivity of the nucleation pad. For the nanowire with notch, it was demonstrated that the coercivities were different at negative and positive field. But for such case, there is a relationship observed between the percentage notch depth and the coercivity at the junction
A return to first principles in unjust enrichment: Kerr v. Baranow
No full textThe article focuses on the advances made by the Supreme Court of Canada in the law of unjust enrichment on the case of Kerr versus Baranow which was clarified by Cromwell J. by returning to the first principles of unjust enrichment. The author states that the failure of the court to recognize the similarities between resulting trusts and restitution is regrettable. He states that the joint family venture concept of Cromwell J. that is dissociated from unjust enrichment is successful
International Harmonization and the Gains from Trade
No full textInternational harmonization of standards and regulations is often a goal expressed in trade agreements because it is expected to yield gains from trade. Absence of progress toward harmonization is often interpreted as being motivated by protectionism, with differences in standards and regulations seen as non-tariff barriers. While protectionism may well be the source of resistance to harmonization, there may be other reasons it is not pursued. These alternative explanations have not received much attention from economists. In this article some of these alternatives are outlined - demand effects from altering standards, switching costs, proprietary technologies. The article concludes that proposals for international harmonization need to be scrutinized carefully.demand effects, harmonization, regulation, standards, switching costs, TBT, International Relations/Trade,
The likely regional impacts of an agricultural emissions policy in New Zealand: Preliminary analysis
No full textHendy and Kerr (2005b) find that an emissions charge on agricultural methane and nitrous oxide of $25 per tonne of carbon dioxide (CO2) equivalent would be likely to reduce New Zealand's net land-use related emissions for commitment period one in the order of 3%, with full accounting. The costs per farmer and as a percentage of profit would be very high. This paper considers the regional impacts of such a policy in New Zealand by allocating the emission charge across space according to the location of animals. We then combine our emissions charge information with data on the socio-economic characteristics of the affected areas. Obviously rural areas are heavily affected. In many respects, for example median income, ethnic mix, and percentage of working people with a university degree, the rural areas most affected have very similar socio-economic characteristics to other parts of rural New Zealand. Only in two ways do they appear to differ. Our findings indicate that areas with high emission costs tend to have high employment rates, but that they also have a disproportionately high number of unqualified people.climate change, land use, social impacts, methane, nitrous oxide, dairy, sheep, beef, distribution of costs, regional

Isolation of steroidal glycosides from the Caribbean SpongePandaros acanthifolium
No full textFour new steroidal glycosides, acanthifoliosides G-J (1-4), were isolated as minor constituents from the Caribbean marine sponge Pandaros acanthifolium. These metabolites are characterized by a highly oxygenated D ring and the presence of a disaccharide rhamnose-glucose residue and a rhamnose at positions C-3 and C-15, respectively. Their structures were established on the basis of extensive interpretation of 1D and 2D NMR data and HRESIMS analyses. The absolute configurations of the glucose and rhamnose sugars were determined by preparing aldose o-tolylthiocarbamate derivatives and comparison to authentic standards by LC/HRESIMS. Acanthifolioside G (1) exhibited antioxidant and cytoprotective activities
Contextual analysis report: participatory citizenship in the European Union Institute of Education
No full textThe concept of citizenship as merely a legal concept has been considered too narrow for modern democratic society for a number of reasons:? Having legal rights is insufficient to enable equal possibilities for all citizens toactivate their rights. Participatory forms of Citizenship require the capability to exercise rights.? Gaining and maintaining rights requires constant action and vigilance from citizens,and a legal definition does not encompass these processes.? The legal definition emphasizes rights, and places less emphasis on obligations.Obligations of the state upon the citizen are not always legally framed, but occur as citizens’ perceptions of norms. These participatory norms, for example voting, are crucial for the health of democracy.? The legal definition focuses on the relationship between the state and the individual,and ignores the relationship between citizens and the associations they form, as wellas the importance of associative life in the balance of democracy. In this regard,citizens need to participate in civic and political life in order to ensure theaccountability of the state, and the legitimation of democrac
