Nosema ceranae is a recently described, widespread microsporidian parasite of Apis mellifera that has raised concerns as to whether it is contributing to increased colony losses. To better understand this parasite, investigations were made into the seasonality of infections, alternative transmission mechanisms, and potential control approaches. All studies used real-time PCR with specific primers and probes for N. ceranae, as well as traditional spore analysis. Monthly colony monitoring in Virginia showed that N. ceranae was present yearlong with the highest levels observed in April-June and lower levels through the fall and winter. There was no difference in infection levels among bees sampled from different areas of the hive regardless of the time of year. Additionally, N. ceranae infects all castes of the colony. Drones of different ages, including pupae, in-hive, and flying drones, were found to be infected at low levels with infections most prevalent during peak annual levels in April-June. Approximately 5% of flying drones had moderate to high levels of infection indicating that flying drones, which would be the most likely age group to drift, could assist in the horizontal transmission of N. ceranae both within and between apiaries. Immature and mated queens were also found to be infected at low levels. Infection in the ovaries and spermathecae suggests the possibility for vertical transmission. Finally, control of N. ceranae is thought to improve the health of bees and to reduce colony losses. Fall fumagillin treatments and winter stimulative pollen feeding were compared. Neither treatment significantly lowered N. ceranae levels in colonies sampled 3-6 months later, nor did they significantly improve colony survival. Due to the high cost of treatment and the time required, we do not recommend either treatment for N. ceranae infections during the fall. Colony winter losses due solely to N. ceranae seem unlikely because levels of N. ceranae were low. Impacts from N. ceranae infections were also minimal during the summer as productive colonies had some of the highest levels of infection. Although N. ceranae is prevalent throughout hives, it does not seem to be a major cause of colony losses. / Ph. D.

The queens graph Qn has the squares of then x n chessboard as its vertices; two squares are adjacent if they are in the same row, column or diagonal. A set D of squares of Qn is a dominating set for Qn if every square of Qn is either in D or adjacent to a square in D. If no two squares of a set I are adjacent then I is an independent set. Let 'J'(Qn) denote the minimum size of a dominating set of Qn and let i(Qn) denote the minimum size of an independent dominating set of Qn. The main purpose of this thesis is to determine new values for'!'( Qn). We begin by discussing the most important known lower bounds for 'J'(Qn) in Chapter 2. In Chapter 3 we state the hitherto known values of 'J'(Qn) and explain how they were determined. We briefly explain how to obtain all non-isomorphic minimum dominating sets for Q8 (listed in Appendix A). It is often useful to study these small dominating sets to look for patterns and possible generalisations. In Chapter 4 we determine new values for')' ( Q69 ) , ')' ( Q77 ), ')' ( Q30 ) and i (Q45 ) by considering asymmetric and symmetric dominating sets for the case n = 4k + 1 and in Chapter 5 we search for dominating sets for the case n = 4k + 3, thus determining the values of 'I' ( Q19) and 'I' (Q31 ). In Chapter 6 we prove the upper bound')' (Qn) :s; 1 8 5n + 0 (1), which is better than known bounds in the literature and in Chapter 7 we consider dominating sets on hexagonal boards. Finally, in Chapter 8 we determine the irredundance number for the hexagonal boards H5 and H7, as well as for Q5 and Q6 / Mathematical Sciences / D.Phil. (Applied Mathematics)

It was thought until recently that in queenless colonies of species from Plebeia, Friesella and Scaptotrigona genera, among others, would not be possible the establishment of a new queen unless the colony had already a royal cell or an imprisoned queen. Nevertheless it has already been observed that Plebeia lucii queenless mini-colonies produce emergency queens building auxiliary cells closely to pre-existing brood cells. The aims of this study were to study the royal cells construction process in P. lucii queenright colonies and to verify if emergency queens are produced in response of the colonies orphan condition. The royal cells in queenright colonies were produced by the auxiliary cell addition in close contact to brood cells housing larva that had already finished eating but did not begin defecation. The connection hole between the two cells was opened by the larva, which, through this, consumed the additional food, becoming thus a queen. P. lucii queenless colonies responded to the colony orphan condition producing royal cells by the auxiliary cell addition process. From the 43 auxiliary cells produced in queenless colonies, 34 resulted in royal cells. / As rainhas são fundamentais para a sobrevivência das colônias de organismos eussociais. Até recentemente, acreditava-se que em colônias órfãs de espécies dos gêneros Plebeia, Friesella e Scaptotrigona, entre outras, não era possível o estabelecimento de uma nova rainha, caso não houvesse previamente uma célula real ou rainha aprisionada na colônia. Entretanto, já foi observado que mini-colônias de Plebeia lucii, submetidas à condição de orfandade, produzem rainhas de emergência pelo processo de adição de células auxiliares a células de cria pré-existentes. Assim, o presente trabalho teve como objetivos estudar o processo pelo qual são construídas as células reais em colônias normais de P. lucii e verificar se rainhas de emergência são produzidas em resposta à condição de orfandade da colônia. Nas colônias normais, as células reais são produzidas pela adição de célula auxiliar construída por operárias, adjacente a células cujas larvas estejam terminando de se alimentar e que não tenham iniciado a eliminação das fezes. A larva estabelece uma conexão entre as células através da qual consome também o alimento da célula auxiliar, tornando-se assim uma rainha. As colônias órfãs de P. lucii responderam à condição de orfandade produzindo células reais pelo mesmo processo que colônias normais. Das 43 células auxiliares construídas em colônias órfãs de P. lucii, 34 resultaram em células reais.

Em seu processo de montagem, as drags desafiam composições estratificadas de conceitos de gênero, de corpo, de aparência, de subjetividade, nos apontando para cruzamentos entre modos de vestir, maneiras de viver e formas de pensar. A pesquisa busca fugir de discursos molares, dominantes, e recorre, em seu auxílio, a conceitos propostos por autores tais como Deleuze, Guattari, Rolnik, Butler, Preciado, Bento, Preciosa, Miller e Bollon, entre outros, de falas das drag queens Kinaidos, La Beauty, Amanda Fierce, Duda Flux, de relatos autobiográficos, de fotografias de Nikki S Lee, dos filmes Paris is Burning e Morrer como um Homem. Costura-se, assim, um texto-roupa fragmentado, no qual sujeito e objeto se confundem, se entrelaçam. A investigação se encerra consciente de que se trata de um caminho inacabado e em constante transformação. / This dissertation addresses the impersonation of drag queens as a way to think both conceptually and to reflect on the existence. In their impersonation process, drags challenge stratified compositions of concepts as gender, body, appearance, subjectivity in pointing to intersections between modes of dress, ways of living and ways of thinking. The research seeks to escape from molars, dominant discourses, and uses, to its aid, the concepts proposed by authors such as Deleuze, Guattari, Rolnik, Butler, Preciado, Benedict, Precious, Miller and Bollon, among others, statements of drag queens Kinaidos, La Beauty, Amanda Fierce, Duda Flux, of autobiographical accounts, photographs of Nikki S Lee, films Paris is Burning and To die like a man. We sew, thus, a fragmented text-blank, in which subject and object are confused, intertwine. The research concludes aware that this is an unfinished and constantly changing path.

This thesis examines the portraiture of the Ptolemaic queen Arsinoë II (lived ca. 318- 268 BC), which appears on a variety of media including: coinage, intaglios, oinochoai (a type of wine jug), statuettes, sculpture-in-the-round, relief stelai, and temple reliefs. The overall aim of this study is to reveal the agency behind the portraiture of Arsinoë (labelled the ‘queen-image’) so as to show that her image was a fabrication of the Ptolemaic administration. In order to demonstrate this, a unique methodological approach is used that comprises elements from semiotics, Alfred Gell’s agency theory, and Richard Dyer’s star theory. This new theory is applied to the media portraying the queen that is collected into an accompanying catalogue composed of eighty-one entries, which includes both Greek and Egyptian-style representations for a holistic approach to the evidence. The material depicting the queen-image encompasses a large span of time: from the early 3rd into the 1st century BC. The first two chapters focus on the iconographic components making up Arsinoë’s portraits and categorise these elements based on the type of information – personal or public – that they convey about the queen. The iconographic elements of the queen-image are interpreted as embedded with conscious meaning: these pictorial signs are specifically chosen by the Ptolemaic administration because of the symbolism attached to them. Therefore, analysing their symbolic meaning provides insight into the royal ideology communicated by Arsinoë’s image. Chapter 3 considers the level of agency that the Ptolemaic administration had over individual portrait media in order to demonstrate the influence the administration had in the manufacture of the queen-image. Chapter 4 examines the display context of the portrait media so as to determine the accessibility of Arsinoë’s image to the population of Hellenistic Egypt thereby making it possible to characterise the audience of these works. The display context of the queen-image dictates both the types of people encountering her portrait and demonstrates the Ptolemaic administration’s success in promoting the queen to different groups. Finally, it is argued that the Ptolemaic administration used Arsinoë’s portraiture to propagate Lagid queenship, which incorporated concepts of legitimacy, authority, piety, attractiveness, fertility, and idealised femininity. As the first Ptolemaic queen to be depicted in portraitre, Arsinoë’s image becomes a model for queenship imitated by later royal women as well as a legitimising symbol for succeeding kings.
