The preface to The Picture of Dorian Gray is often dismissed as merely an addendum to the novel intended to detract hostile readers and absolve the text itself of any accusations of immorality. When coupled with the narrative itself, however, the novel shows both the impossibility of producing the new through traditional notions of revolution, as well as the way in which the Deleuzian conception of judgment inhibits Dorian from ever viewing the portrait as insignificantly amoral, as not symbolic of his sins. Yet the preface, coupled with the various aesthetic objects in the text, is productive of a new form of judgment, one that does not reproduce the same moral order. This takes the form of a "useless" judgment. When Lord Henry claims he wishes to change nothing in England but the "weather," this is the same as the portrait, returned to its original form, hanging over Dorian's body at the novel's end: neither is a judgment with a use, but rather a judgment of a work of art that produces nothing in the work of art. Lord Henry cannot change the weather, and the portrait's changes do not help or affect Dorian in any way. Thus we see the answer to Deleuze's question of what the "refusal of work" would look like. Art is "quite useless" in that it is both extremely removed from any and all spheres concerned with moral order, and also fairly indifferent to this fact and Dorian's concern with maintaining a world organized by useful symbols.

We define new metrics for linear codes over the ring Fq[u]/(ut) via an Fq-module monomorphism on linear codes over Fq. The construction generalizes the Gray map, Gray weight, and Lee weight; and the technique allows us to find some new optimal linear codes and their weight enumerator polynomial.

The present study focused on using food wastes and feed supplements, e.g. enzymes (bromelain and papain), baker’s yeast and Traditional Chinese Medicines (TCMs) for rearing freshwater fish (grass carp and grey mullet) in Hong Kong. Different types of food wastes, e.g. meats, bones, cereals, fruits and vegetables were collected from local hotels, mixed in different ratios and processed into feed pellets for feeding trials. The cereal dominant food waste feed (FW A) was more suitable for grass carp and grey mullet, with the best growth performance (e.g. feed conversion ratio (FCR), specific growth rate (SGR)) and higher protein digestibility (in grass carp), compared to FW B and FW C which contained higher proportions of meat products. The NBT (Nitroblue Tetrazolium) activities in blood and plasma protein levels were decreased in the grass carp, cultured with food waste feeds without any supplements, compared to the commercial feed, Jinfeng®, 613 formulation (Control). Upgrading FW A by the addition of 1% and 2% mixtures of bromelain and papain significantly increased the feed protein solubility and subsequent to growth (SGR and relative weight gain (RWG)) and feed utilization (e.g. apparent net protein utilization (ANPU), protein efficiency ratio (PER)) in both fish species. The protein and feed utilizations by grass carp were also promoted by the yeast supplements with the optimal dose of 2.5% yeast (S. cerevisiae) added to FW A upgraded by enzymes. This showed that yeast could further enhance nutrient utilization contained in feeds after addition of bromelain and papain. The in vitro study on the grass carp’s plasma treated with TCM extracts also showed that TCM extracts could stimulate plasma bactericidal activity (on Aeromonas hydrophila), possibly through enhancing plasma complement activity. The formulation with Radix scutellaria, Rhizoma coptidis, Herba andrographis and Radix sophorae flavescentis in the ratio of 1:1:2:3 was more effective in enhancing plasma bactericidal activity than single TCM extracts. Besides, R. coptidis and R. scutellaria possessed the strongest antimicrobial activity (in vitro) on fish pathogens (such as A. hydrophila, Lactococcus garvieae and Vibrio cholerae) among the 17 tested TCMs. In addition, TCMs were less likely for developing drug resistant pathogens than antibiotics. Grass carp immunity (NBT activity in blood, plasma bactericidal activity and total immunoglobulin level) was boosted by the addition of TCM formulation and baker’s yeast (S. cerevisiae). The disease resistance to pathogen (A. hydrophila) was also enhanced, with significantly lower mortalities observed in groups feeding with TCM (1 and 2% for 21 to 28 days) and baker’s yeast (2.5 and 5% for 28-56 days). The uses of yeast and TCMs led to positive effects on growth, immunity and disease resistance to pathogens in fish, but the effects (grass carp) were less effectual when both were supplemented in feed. The combined use of both supplements may impair the effects of TCM formulation or yeast in the modulation of gut mircoflora, and upset the balance of beneficial microbial communities. The present study demonstrated the feasibility of using feed supplements (TCM and baker’s yeast) to enhance fish immunity and enzymes upgraded food waste feeds for rearing fish, for the development of a more sustainable aquaculture in Hong Kong.

abstract: Gray codes are perhaps the best known structures for listing sequences of combinatorial objects, such as binary strings. Simply defined as a minimal change listing, Gray codes vary greatly both in structure and in the types of objects that they list. More specific types of Gray codes are universal cycles and overlap sequences. Universal cycles are Gray codes on a set of strings of length n in which the first n-1 letters of one object are the same as the last n-1 letters of its predecessor in the listing. Overlap sequences allow this overlap to vary between 1 and n-1. Some of our main contributions to the areas of Gray codes and universal cycles include a new Gray code algorithm for fixed weight m-ary words, and results on the existence of universal cycles for weak orders on [n]. Overlap cycles are a relatively new structure with very few published results. We prove the existence of s-overlap cycles for k-permutations of [n], which has been an open research problem for several years, as well as constructing 1- overlap cycles for Steiner triple and quadruple systems of every order. Also included are various other results of a similar nature covering other structures such as binary strings, m-ary strings, subsets, permutations, weak orders, partitions, and designs. These listing structures lend themselves readily to some classes of combinatorial objects, such as binary n-tuples and m-ary n-tuples. Others require more work to find an appropriate structure, such as k-subsets of an n-set, weak orders, and designs. Still more require a modification in the representation of the objects to fit these structures, such as partitions. Determining when and how we can fit these sets of objects into our three listing structures is the focus of this dissertation. / Dissertation/Thesis / Ph.D. Mathematics 2012

Existem evidências que indicam um envolvimento da neurotransmissão noradrenérgica da SCPD na modulação da ansiedade, no entanto, não existe evidência sobre sua participação nos ataques de pânico. Neste sentido, o objetivo do presente estudo foi investigar a participação da neurotransmissão noradrenérgica da SCPD na mediação de comportamentos defensivos relacionados ao TAG e ao TP em animais testados no labirinto em T elevado (LTE), um modelo animal que associa a resposta de esquiva inibitória ao TAG e a resposta de fuga ao TP. Para tal, ratos Wistar receberam a administração intra-SCPD de noradrenalina (10, 30 ou 60 nmoles/0,1μL) ou salina e foram testados no LTE. Adicionalmente, investigamos o efeito do pré-tratamento intra-SCPD com os antagonistas não seletivos de receptores alfa e beta-adrenérgicos, fentolamina e propranolol, respectivamente, no efeito da injeção de noradrenalina na mesma estrutura. Nossos resultados mostram que a administração intra-SCPD de noradrenalina na maior dose prejudicou a aquisição da esquiva inibitória, sugerindo um efeito do tipo ansiolítico, porém não apresentou efeito sobre a resposta de fuga no LTE. Além disso, a injeção de noradrenalina não alterou a atividade locomotora dos animais no teste do campo aberto, sugerindo que o efeito ansiolítico não foi devido a um aumento na atividade exploratória. Os resultados mostram ainda que o pré-tratamento intra-SCPD de fentolamina ou propranolol atenuou o efeito do tipo ansiolítico da noradrenalina. Assim, o presente estudo sugere um envolvimento da neurotransmissão noradrenérgica na SCPD, via receptores alfa e beta-adrenérgicos, em reações defensivas associadas com o TAG, mas não com o TP em animais submetidos ao LTE.

Based on the voices within the utterances that make up the characters' dialogs, our aim is to interpret their self-consciousness, their views on art itself, and to what extent they stand in relation to Victorian England, the space and the time of the narrative; Dorian Gray, as a disciple of Lord Henry Wotton in the implementation of the ideas of a socalled new Hedonism, and as a Doppelgänger materialized by his picture; Basil Hallward, as a conservative individual, in favor of moral values, yet as an artist refracting the Realism of his days, by pursuing the perfect aesthetic representation in a combination of Antiquity and Renaissance forms and the Romantic soul, which preceded Realism; and lord Henry Wotton, 'the illusionist of words', who makes his point by refracting the views of his time and space by resorting to the irony and the maxims of epigrams. The latter are also resorted to by Wilde in the whole preface of 1891's version of The picture of Dorian Gray, so as to stand against the myriad of critical reviews which considered his only novel as 'immoral'. We will address Mikhail Bakhtin's self-consciousness theory, as well as Walter Pater's and Karl Beckson's in regard to the Aesthetic movement. Last, but no least, Munira Mutran's and Richard Elmann's writings on Wilde's autobiographical works related to his position as an aesthete and a dandy, yet by no means do we intend to affirm that The picture of Dorian Gray is mainly an autobiography, but an expression "of the self as having multiple possibilities", in Elmann's words. As a conclusion, we will aim to identify the characters' cosmovision, in a never-ending process of reflecting and / or refracting their time and space values. / O presente trabalho propõe-se a analisar a segunda versão da obra O retrato de Dorian Gray, publicada no ano de 1891, do autor irlandês Oscar Wilde, focalizando três personagens principais: Dorian Gray, Basil Hallward e lorde Henry Wotton. Com base nas vozes das enunciações que compõem os diálogos dos quais participam as referidas personagens, nosso objetivo é o de investigar como se dá a construção de suas autoconsciências, de discutir os conceitos de arte que essas personagens defendem e a forma como cada uma delas se posiciona em relação à Inglaterra vitoriana, espaço e tempo da narrativa: Dorian Gray, como discípulo de lorde Henry Wotton na implementação de um novo Hedonismo e como alter ego ou duplo, materializado em seu retrato; Basil Hallward, como indivíduo conservador, consoante com os valores morais da época em que vive, mas como artista que refrata as artes realistas de seu tempo, na busca pela representação estética perfeita que combine as formas clássicas da Antiguidade e do Renascimento com a alma do Romantismo; e lorde Henry Wotton, “o eficiente mestre da palavra” que enuncia sua visão refratária aos valores morais de seu tempo e de seu espaço, por meio da ironia e das máximas, transmitidas pelo recurso dos epigramas. Estes também são utilizados por Wilde para se posicionar em relação à miríade de críticas que recebeu quando da primeira publicação do romance, em 1890, pois diversos periódicos especializados em literatura consideraram o único romance publicado pelo autor como sendo imoral. Examinaremos a integralidade do prefácio à versão de 1891, amparados na teoria bakhtiniana, no que toca à autoconsciência, bem como nas obras de Walter Pater e de Karl Beckson, para a contextualização do Esteticismo e, por fim, nas de Munira Mutran e de Richard Elmann, para analisarmos as possíveis relações das personagens com o universo autobiográfico do autor esteta e dandy, não com o objetivo de concluirmos que a obra em questão se trate de autobiografia, mas sim de uma narrativa composta de personagens que representem o "ser de possibilidades múltiplas", conforme expressão de Elmann. Feito isso, orientar-nos-emos a discutir aspectos nas cosmovisões das personagens que refletem e refratam os valores de seu tempo e de seu espaço.
