End-winding effect on shalft voltage in AC generators

This paper presents effects of end-winding on shaft voltage in AC generators. A variety of design parameters have been considered to calculate the parasitic capacitive couplings in the machine structure with Finite Elements simulations and mathematical calculations. End-winding capacitances have also been calculated to have a precise estimation of shaft voltage and its relationship with design parameters in AC generators.

Unraveling Public Good Games: The Role of Priors

This paper provides experimental evidence on how players predict end game effects in a linear public good game. Our regression analysis yields a measure of the relative importance of priors and signals on subjects\' beliefs on contributions and allow us to conclude that, firstly, the weight of the signal is relatively unimportant, while priors have a large weight and, secondly, priors are the same for all periods. Hence, subjects do not expect end game effects and there is very little updating of beliefs.

Effect of Playing Interactive Computer Game on Distress of Insulin Injection Among Type 1 Diabetic Children

Background: Diabetic children and their families experience high level stress because of daily insulin injection. Objectives: This study was conducted to investigate the impact of an interactive computer game on behavioral distress due to insulin injection among diabetic children. Patients and Methods: In this clinical trial, thirty children (3-12 years) with type 1 diabetes who needed daily insulin injection were recruited and allocated randomly into two groups. Children in intervention groups received an interactive computer game and asked to play at home for a week. No special intervention was done for control group. The behavioral distress of groups was assessed before, during and after the intervention by Observational Scale of Behavioral Distress–Revised (OSBD-R). Results: Repeated measure ANOVA test showed no significantly difference of OSBD-R over time for control group (P = 0.08), but this changes is signification in the study group (P = 0.001). Comparison mean score of distress were significantly different between two groups (P = 0.03). Conclusions: According to the findings, playing interactive computer game can decrease behavioral distress induced by insulin injection in type 1 diabetic children. It seems this game can be beneficial to be used alongside other interventions.

Tabernacle-Game world

Tabernacle is an experimental game world-building project which explores the relationship between the map and the 3-dimensional visualisation enabled by high-end game engines. The project is named after the 6th century tabernacle maps of Cosmas Indicopleustes in his Christian Topography. These maps articulate a cultural or metaphoric, rather than measured view of the world, contravening Alper's distinction which observes that “maps are measurement, art is experience”. The project builds on previous research into the use of game engines and 3D navigable representation to enable cultural experience, particularly non-Western cultural experiences and ways of seeing. Like the earlier research, Tabernacle highlights the problematic disjuncture between the modern Cartesian map structures of the engine and the mapping traditions of non-Western cultures. Tabernacle represents a practice-based research provocation. The project exposes assumptions about the maps which underpin 3D game worlds, and the autocratic tendencies of world construction software. This research is of critical importance as game engines and simulation technologies are becoming more popular in the recreation of culture and history. A key learning from the Tabernacle project was the ways in which available game engines – technologies with roots in the Enlightenment - constrained the team’s ability to represent a very different culture with a different conceptualisation of space and maps. Understanding the cultural legacies of the software itself is critical as we are tempted by the opportunities for representation of culture and history that they seem to offer. The project was presented at Perth Digital Arts and Culture in 2007 and reiterated using a different game engine in 2009. Further reflections were discussed in a conference paper presented at OZCHI 2009 and a peer-reviewed journal article, and insights gained from the experience continue to inform the author’s research.

CSG A Greener Tomorrow : Comprehensive Organizational and Socialistic Report

Humans have altered environments and enhanced their wellbeing unlike any other creature on the planet (Hielman & Donda, 2007); this is no different whether the environment is ecological, social or organizational. In recent times, the debate regarding greenhouse effects on the global weather patterns and the sustainment of the earth’s temperature necessary for life support has become quite infamously problematic as society pushes to find new sources of energy both renewable and environmentally sustainable. The feedback received on CSG from both government and companies alike is that the opportunities this industry creates has a lasting range of social and economic benefits worth over fifty (50) billion dollars in projects (Queensland Government, 2013). This however, has been overshadowed by social activist and lobbyist groups as ‘Lock the Gate Alliance’ saying, as one part of their report noted from the National Water Commission, “coal seam gas development could cause significant social impacts by disrupting current land-use practices and the local environment through infrastructure construction and access” (Lock the Gate Alliance, n.d.), and “In recent years both a NSW and Federal Senate inquiry into coal seam gas production were deliberately mislead by an organization that claims to work on behalf of the farming community, This is the battle for the end of the fossil fuel industry. This is the end game..." (Ward, 2013).

Pharmakologische Hemmung strahleninduzierter Tumorzell-Endothelzell-Interaktionen in vitro und Metastasierungsprozesse in vivo

Exposition von Endothelzellen mit ionisierender Strahlung (IR) oder Behandlung mit inflammatorischen Zytokinen (z. B. TNFa) induziert über eine Rho-GTPasen abhängige NF-kB-Aktivierung die Expression verschiedener Zelladhäsionsmoleküle, u. a. auch von E-Selektin. E-Selektin vermittelt die Adhäsion von Tumorzellen (TC) an Endothelzellen und ist daher vermutlich an der Extravasation von zirkulierenden Tumorzellen beteiligt. HMG-CoA-Reduktase-Inhibitoren (Statine), welche eine breite klinische Anwendung als Lipidsenker erfahren, sind in der Lage, Rho-GTPasen und die durch sie vermittelten Signalwege zu hemmen. Daher sollten Statine wie Lovastatin auch Zell-Zell-Adhäsionsvorgänge beeinflussen. Die vorliegende Arbeit widmet sich den Mechanismen, mit denen IR und TNF in Endothel- und/oder Tumorzellen pro-adhäsive Faktoren induzieren können und ob diese Effekte durch Lovastatin beeinflussbar sind. Zu diesem Zweck wurde mittels eines ELISA-basierenden Zelladhäsions-Assays die Auswirkung von IR und TNF auf Zell-Zell-Kontakte zwischen humanen Tumorzellen (u. a. Kolonkarzinomzellen (HT29)) und humanen, venösen Nabelschnurendothelzellen (HUVEC) analysiert. Zudem wurden die Effekte einer Lovastatinvorbehandlung von TC und/oder HUVEC auf TC-HUVEC-Adhäsion untersucht. Des Weiteren wurden die Wirkungen des sLex-Mimetikums Glycyrrhizin und des Rac1-spezifischen „small-molecule“ Inhibitors NSC23766 auf TC-HUVEC-Adhäsion überprüft. Zusätzlich wurde die strahleninduzierbare mRNA-Expression von diversen Zelladhäsionsmolekülen, Metastasierungsfaktoren und DNA-Reparatur-Genen mittels qRT-PCR (Real-Time Analysen) quantitativ erfasst. Um die erhaltenen in vitro Ergebnisse auch in vivo zu bestätigen, untersuchten wir den Effekt einer Ganzkörperbestrahlung (TBI) von BALB/c-Mäusen auf die Expression von pro-adhäsiven Faktoren. Zur Analyse der Tumorzell-Extravasation wurden Tumorzellen in die laterale Schwanzvene immundefizienter Mäuse injiziert und anschließend eine Ganzkörperbestrahlung durchgeführt (4 Gy). Nach einer Wartezeit von 4 Wochen wurde ein erhöhtes Auftreten von Lungenmetastasen beobachtet, welches durch Vorbehandlung der Tiere mit Statinen, NSC23766 oder Glycyrrhizin blockiert werden konnte. Zusammenfassend konnte somit ein Einfluss von IR auf die Expression verschiedener Zelladhäsionsmoleküle in vitro und auf die Extravasation zirkulierender Tumorzellen in vivo festgestellt werden. Diese pro-metastatischen Strahleneffekte konnten durch pharmakologische Hemmung Rho-regulierter Signalwege abgeschwächt werden.

Economic Implications of Enlargement. Bruges European Economic Policy (BEEP) Briefing 1/2002

The Eastern enlargement is about to be decided by the European Council. As expected, the “end game “ of the negotiations and assessments is heavily biased by a narrow perspective on net transfers, on income compensations to Central European farmers and on the psychological politics of a single “big bang “. None of these three so-called key items of the end game are of much relevance to appreciate the significance of enlargement. Net transfers have little to do with the costs and benefits of club membership for countries which pay, and can lead to addiction and lethargy rather than extra growth if market integration, macro-economic stability and domestic reforms are not taken serious (as the case of Greece before 1997 has demonstrated). Income compensations for Eastern farmers are crucial for this pressure group, and symbolically of some importance in domestic politics because of the perversity that rich farmers get more, but their absence is likely to serve the public interest in candidate countries far better. And being part of the big bang, as against getting in one or three years later, has assumed a dramatic meaning during this end game, far beyond its true proportions. This hectic European theatre tends to obscure what enlargement is mainly about, now that the stability and values have been secured for the peoples from Central Europe. In a guaranteed setting of peace, freedom and security, enlargement is about greater prosperity.

Is a Concordat over Ukraine now conceivable with Mishka the bear? CEPS Commentary, 21 December 2014

With the tumultuous year of ever-changing episodes in Ukraine coming to a close – from Yanukovich reneging at Vilnius last November, to the new Maidan, to Yanukovich fleeing for his life, to Russia’s annexation of Crimea and incursions into the eastern Donbass, the election of pro-European President Poroshenko, the war with over 4,000 dead, the election of a new pro-European parliament and now the crash of the rouble – Michael Emerson sees at last a possible the end-game in sight. In this commentary, he sketches the essential elements of a Concordat to be struck between Russia, Ukraine and the West that would allow the eastern Donbass to be drawn into more normal processes of political and economic negotiation and the badly wounded Russia to gradually return to more normal international relations.

Democratic governance and the rule of law : lessons from Colombia /

"Colombia has experienced conflict for decades. In the 1990s it was a paradigm of the failing state, beset with all manner of troubles: terrorism, kidnapping, murder, drug trafficking, corruption, an economic downturn of major scope, general lawlessness, and brain drain. Today the country is much safer, and the agents of violence are clearly on the defensive. Nonetheless, much work lies ahead to secure the democratic system. Security and the rule of law are fundamental to the task. As the monopoly over the legitimate use of force is established, democratic governance also needs the architecture of law: ministry of justice, courts, legislative scrutiny, law enforcement agencies, regulatory bodies, public defenders, police, correctional system, legal statutes, contracts, university level academic education to train lawyers, judges, and investigators, along with engagement with civil society to promote a culture of lawfulness. Security without the rule of law puts a society at risk of falling into a Hobbesian hell."--P. v.

Polioviruses and other enteroviruses isolated from faecal samples of patients with acute flaccid paralysis in Australia, 1996-2004

Background: Acute flaccid paralysis (AFP) is the most common clinical presentation of acute poliovirus infection, occurring in 0.1-1% of infected cases. AFP surveillance has been used world-wide to monitor the control and eradication of circulating wild poliovirus. This study aims to review the significance of all enteroviruses, including polioviruses, isolated from patients with AFP in Australia between 1996 and 2004. Methods: We undertook a retrospective review of all notified cases of AFP, aged 0-15 years and resident in Australia at the time of notification. We reviewed all available clinical and virological data for these cases and all records of the Polio Expert Committee, which determined the final classification for all cases. Results: There were 335 notified cases that satisfied the case definition for AFP, 162 (48%) of whom had at least one faecal sample tested. Enteroviruses isolated from the faeces of 26 (16%) of the 162 cases were Coxsackie A24, Coxsackie B5, enterovirus 71, enterovirus 75, echovirus 9, echovirus 11 and echovirus 18. In addition, one or more polioviruses were isolated from the faeces of seven patients. Six of seven polioviruses were characterised as Sabin-like, one was not characterised, but all were considered to be incidental isolates. Five of these cases were classified as infant botulism, one case as transverse myelitis and one as a focal mononeuropathy. Conclusion: With the eradication of circulating wild polioviruses, other enteroviruses are being more commonly identified as the cause of polio-like illnesses. In the polio end game, when there is increased testing for polioviruses, it is important to consider infant botulism as a differential diagnosis in cases presenting with AFP.

A comparative study of cationic liposome and niosome-based adjuvant systems for protein subunit vaccines:characterisation, environmental scanning electron microscopy and immunisation studies in mice

Vesicular adjuvant systems composing dimethyldioctadecylammonium (DDA) can promote both cell-mediated and humoral immune responses to the tuberculosis vaccine fusion protein in mice. However, these DDA preparations were found to be physically unstable, forming aggregates under ambient storage conditions. Therefore there is a need to improve the stability of such systems without undermining their potent adjuvanticity. To this end, the effect of incorporating non-ionic surfactants, such as 1-monopalmitoyl glycerol (MP), in addition to cholesterol (Chol) and trehalose 6,6′-dibehenate (TDB), on the stability and efficacy of these vaccine delivery systems was investigated. Differential scanning calorimetry revealed a reduction in the phase transition temperature (T c) of DDA-based vesicles by ∼12°C when MP and cholesterol (1:1 molar ratio) were incorporated into the DDA system. Transmission electron microscopy (TEM) revealed the addition of MP to DDA vesicles resulted in the formation of multi-lamellar vesicles. Environmental scanning electron microscopy (ESEM) of MP-Chol-DDA-TDB (16:16:4:0.5 μmol) indicated that incorporation of antigen led to increased stability of the vesicles, perhaps as a result of the antigen embedding within the vesicle bilayers. At 4°C DDA liposomes showed significant vesicle aggregation after 28 days, although addition of MP-Chol or TDB was shown to inhibit this instability. Alternatively, at 25°C only the MP-based systems retained their original size. The presence of MP within the vesicle formulation was also shown to promote a sustained release of antigen in-vitro. The adjuvant activity of various systems was tested in mice against three subunit antigens, including mycobacterial fusion protein Ag85b-ESAT-6, and two malarial antigens (Merozoite surface protein 1, MSP1, and the glutamate rich protein, GLURP). The MP- and DDA-based systems induced antibody responses at comparable levels whereas the DDA-based systems induced more powerful cell-mediated immune responses. © 2006 The Authors.

Synthetic studies towards the total synthesis of hexacyclinic acid

In the first chapter of this thesis, published works found in the literature about hexacyclinic acid and FR182877 are reported and commented. A quick summary of the previous work done in the Prunet group is also described. In the second and third chapter, a more detailed account of the work undertaken during this PhD was given. Firstly, syntheses of two ABC tricycles incorporating tert-butyl and (trimethylsilyl)ethyl esters were undertaken. These syntheses include two key steps previously developed in the group, a diastereoselective Michael addition and a Snider cyclisation. Multiple conditions for the hydrolysis of the esters were attempted but none of them gave the desired product. The main part of this work is focused on the synthesis of a CDEF model and in particular about the development of the key step, the formation of a nine-membered ring. Several DEF fragments were synthesised in short synthetic sequences and as single isomers. Six different synthetic pathways were developed in total and a novel method, a Michael/elimination reaction, was found to be a very efficient way to close the desired medium-size ring. From the nine-membered ring, regioselective reduction and palladiumcatalysed allylic substitution led to the formation of the CDF tricycle. Final steps of the synthesis were fruitless and led only to decomposition. A synthesis of a chiral C-ring was also developed during this PhD. II Finally, another project was undertaken, not related to hexacyclinic acid. Methodology developed in the group for the diastereoselective formation of trisubstituted alkenes employing a temporary silicon-tethered ring-closing metathesis was extended to homoallylic alcohols. The first steps of the method were similar to the previous methodology but the end-game had to be modified in favour of an oxidation/reduction sequence to successfully obtain the desired products with the correct geometry. In the fourth chapter, procedures and analytical data for the synthesised compounds previously described are reported.
