Two-dimensional Stokes flow driven by elliptical paddles

A fast and accurate numerical technique is developed for solving the biharmonic equation in a multiply connected domain, in two dimensions. We apply the technique to the computation of slow viscous flow (Stokes flow) driven by multiple stirring rods. Previously, the technique has been restricted to stirring rods of circular cross section; we show here how the prior method fails for noncircular rods and how it may be adapted to accommodate general rod cross sections, provided only that for each there exists a conformal mapping to a circle. Corresponding simulations of the flow are described, and their stirring properties and energy requirements are discussed briefly. In particular the method allows an accurate calculation of the flow when flat paddles are used to stir a fluid chaotically

The Javanese self in portraiture from 1880-1955

This thesis, The Javanese self in portraiture from 1880-1955 examines changing understandings and representations of the Javanese self in painted and photographic portraits spanning 75 years from 1880-1955. During this period, Indonesian modern art followed a trajectory from its 19th century beginnings within the domain of exclusive privilege, through the socially engaged Persagi painters to the opening of the first National art school, Akademi Seni Rupa Indonesia. In tandem there was a dramatic shift in the public’s understanding of two concepts: the modern individual and the nation state of Indonesia. The two however are not mutually inclusive and in many cases the modern individual precluded the nation. One must consider that the colonial state, rather than the Republic, was the defining structure into which many of the major players in Indonesian modern art were born and in which they operated. Furthermore, certain individuals crystallised their sense of national consciousness whilst living abroad and in many instances working in conjunction with the Dutch. In some cases the modern individual was situated in an isolated position, far outside any notions of a shared experience with an imagined community. Whilst this thesis is concerned with the biographies of individuals and is deeply committed to a social history of art, the focus on individuals is not made in order to reveal broader assumptions regarding society, but rather to reveal nuanced and sometimes very personal expressions of modernism. Because the appearances of modernism were not always concurrent or consistent with societal modernity, we cannot plot an uninterrupted or continuous path for Indonesian modern art. Yet a number of societal changes that came about during the period from high colonialism to independence affected class structure and gender, giving rise to altered states of selfhood and new methods of artistic expression. It is precisely the complex set of transactions between the individual, larger society and the economic and political conditions of the time that this thesis sets out to articulate in order to reveal a number of significant characteristics regarding the possibilities of self representation in portraiture. First, the early history of Indonesian modern art is plotted in terms of cooperative relationships between Javanese aristocrats and Dutch men. Secondly, that whilst appearing conservative and pro-Dutch, these Javanese artists were critical in initiating a discourse on modern art and in establishing a position of cultural nationalism, domestically and abroad. Finally, the conjunction of the first two points demonstrates that the history of modern Indonesian art began much earlier than previously believed and, perhaps even more significantly, was attached to the idea of Indonesian cultural and national self-determination at a very early stage of its development

Whole genome metagenomic analysis of the gut microbiome of differently fed infants identifies differences in microbial composition and functional genes, including an absent CRISPR/Cas9 gene in the formula-fed cohort

Background: Advancements in sequencing capabilities have enhanced the study of the human microbiome. There are limited studies focused on the gastro-intestinal (gut) microbiome of infants, particularly the impact of diet between breast-fed (BF) versus formula-fed (FF). It is unclear what effect, if any, early feeding has on short- term or long-term composition and function of the gut microbiome. Results: Using a shotgun metagenomics approach, differences in the gut microbiome between BF (n = 10) and FF (n = 5) infants were detected. A Jaccard distance principle coordinate analysis was able to cluster BF versus FF infants based on the presence or absence of species identified in their gut microbiome. Thirty-two genera were identified as statistically different in the gut microbiome sequenced between BF and FF infants. Furthermore, the computational workflow identified 371 bacterial genes that were statistically different between the BF and FF cohorts in abundance. Only seven genes were lower in abundance (or absent) in the FF cohort compared to the BF cohort, including CRISPR/Cas9; whereas, the remaining candidates, including autotransporter adhesins, were higher in abundance in the FF cohort compared to BF cohort. Conclusions: These studies demonstrated that FF infants have, at an early age, a significantly different gut microbiome with potential implications for function of the fecal microbiota. Interactions between the fecal microbiota and host hinted at here have been linked to numerous diseases. Determining whether these non- abundant or more abundant genes have biological consequence related to infant feeding may aid in under- standing the adult gut microbiome, and the pathogenesis of obesity

Out of Office and In the News: Early Projections of the Clinton Legacy

During the first year after a president has left office, the tone and topic of news media coverage can influence a legacy greatly. This study examines coverage of Bill Clinton during his first year out of office in the New York Times and on network news shows and compares this coverage to that of Ronald Reagan and George Bush during their first years out of office. We find that Clinton received substantially more news coverage during the first year out of office than did either Reagan or Bush, and that Clinton\u27s coverage in the media was also more critical and negative than the coverage received by either of his predecessors

Theresearch resulted in three potential options: Purchase a carrier with a current operating certificate Start a new company Contract an existing operator to perform the operations

Life After the White House: The Public Post-Presidency and the Development of Presidential Legacies

This chapter considers two distinct yet related issues: First, we examine the role that continuing press coverage of a former president plays in the development of a presidential legacy; and second, we consider the impact of Clinton’s lingering presence in the news media in the first year after he left office and how that has shaped the early phase of his legacy. While the historical rankings and public approval ratings of former presidents can and do shift—sometimes dramatically—in the years after leaving office, news coverage during the first year can be important in setting a tone as to how the president will be viewed and the public role that he will assume, as well as what news organizations view as significant from his time in office. A recent study on press coverage of former presidents Gerald Ford, Jimmy Carter, Ronald Reagan and George H.W. Bush suggests that the amount of post-White House coverage decreases after the first year out of office; once both the press and the public are satisfied in knowing how the former president is adjusting to his new responsibilities, then he is no longer viewed as tremendously newsworthy. Therefore, the first year of coverage is important if the former president hopes to create positive coverage through his public activities by working \u27toward the goals in which he believes in the hopes of drawing both media and public attention . . . [since] an ex-president with a rigorous agenda is bound to capture more media attention than one with a less rigorous postpresidential schedule.\u27https://digitalcommons.chapman.edu/polisci_books/1005/thumbnail.jp
