This paper examines the ways in which subject identity obtains in either philosophical or psychoanalytical theory, which subject may be duplicated—and disclosed—in literary narratives via their principles and ideas. ^ The technique has a double approach. First, the thesis examines subject formation in (and by) language, through psychoanalysis as it draws upon abiding mythic resources, phenomenological methods and aims (e.g., the subject as consciousness intending its object), and the existentialist turn. It then brings these ideas and principles to bear upon an analysis of literary works as cultural expressions of these identities. ^ Beginning with scientific and philosophical referents (as opposed to the somewhat ‘inclusive’ analysis of, for example, the New Criticism or explication de texte), allows for alternative readings not previously available to either author or reader. ^ Access to extra-literary sources, theories, and ideas enables a ‘reading’ of the subject on a par with one existing in the Life-World. ^

In recent years, parallel computers have been attracting attention for simulating artificial neural networks (ANN). This is due to the inherent parallelism in ANN. This work is aimed at studying ways of parallelizing adaptive resonance theory (ART), a popular neural network algorithm. The core computations of ART are separated and different strategies of parallelizing ART are discussed. We present mapping strategies for ART 2-A neural network onto ring and mesh architectures. The required parallel architecture is simulated using a parallel architectural simulator, PROTEUS and parallel programs are written using a superset of C for the algorithms presented. A simulation-based scalability study of the algorithm-architecture match is carried out. The various overheads are identified in order to suggest ways of improving the performance. Our main objective is to find out the performance of the ART2-A network on different parallel architectures. (C) 1999 Elsevier Science B.V. All rights reserved.

Con el objetivo de investigar la prevalencia de bacterias entéricas en leches crudas del Departamento de Managua se llevo a efecto el presente trabajo entre Junio y Octubre de 1965. La investigación se llevó a efecto con 37 productores de leche del Departamento de Managua, los cuales la venden a las distintas pasteurizadoras del Departamento. Las muestras fueron tomadas en el momento en que los productores entregan la leche a las Pasteurizadoras, sometiéndolas luego a las pruebas bacteriológicas necesarias para el aislamiento e identificación de las bacterias entericas presentes. Se encontraron cinco géneros de enterobacterias, siendo los más frecuentemente encontrados: Aerobacter en un 62.1%, Escherichis 10.8% y los géneros Salmonella, Shinella y Proteus en un 2.7%. Se encontró que las muestras examinadas estaban contaminadas con germenes estericos en un 81.08%. No se encontró ninguna relación aparente entre la contaminación de los germenes entericos y la prueba de reducción de azul de metileno.

A qualitative and quantitative investigation of the bacterial flora of the gut of the African snakehead, Channa obscura was undertaken. The types of bacteria isolated from the different parts of the gut of C. obscura include Pseudomonas, Streptococcus, Citrobacter and Proteus. The coliform (Escherichia coli, Enterobacter) and some other Enterobacteriaceae such as Salmonella were also present. The stomach and intestine were found to have a preponderance of Pseudomonas and Vibrio species. Klebsiella sp. and Bacillus sp. (only in the pyloric caeca) were also isolated. On the whole, the correlation coefficients of the two incubation temperatures showed a high statistical significance. Thus the bacterial load of the gut of C. obscura has been shown as a function of temperature

As infecções associadas aos cuidados de saúde constituem um problema grave nas unidades hospitalares bem como nos serviços de atendimento extra-hospitalares. Diferentemente de outros países, no Brasil, existe uma incidência alta dessas infecções causadas por microorganismos Gram-negativos produtores de β-lactamase de espectroestendido (ESBL). Estas enzimas hidrolisam compostos β-lactâmicos e são consideradas mundialmente como de importância clínica, pois a localização de seus genes emelementos móveis facilitam a transmissão cruzada. Este estudo foi realizado com amostras bacterianas isoladas de material clínico e de fezes de pacientes internados em um hospital da rede pública no Rio de Janeiro, Brasil. Estes pacientes estavam internados em duas unidades de terapia intensiva cardiológica, no período de janeiro a dezembro de 2007. O estudo teve por objetivo realizar a caracterização fenotípica e genotípica desses isolados associados à colonização ou infecção dos pacientes. Os testes fenotípicos e genotípicos foram realizados na Universidade do Estado do Rio de Janeiro e incluíram provas bioquímicas, teste de susceptibilidade, teste confirmatório para a expressão da produção da enzima ESBL e Reação de Polimerase em Cadeia (PCR) com iniciadores específicos para cinco genes: blaTEM, blaSHV, CTX-M1, Toho1 e AmpC. As espécies bactérianas mais frequentemente isoladas foram Escherichia coli (25%) e Klebsiella pneumoniae (30,56%), e os genes mais prevalentes foram blaTEM (41,6%), AMPC (41,6%) blaSHV (33,3%), CTX-M1 (25%), e Toho1 (19,44%). Identificamos em 25% das amostras enterobactérias que não eram E. coli, K. pneumoniae ou Proteus sp, com fenótipo para ESBL e a expressão dos mesmos genes, confirmando a necessidade de investigação nestes grupos microbianos. O substrato mais sensível para a expressão da área de sinergismo no Teste de Aproximação foi o ceftriaxone (80%). Identificamos também que 17% das amostras positivas para ESBL apresentaram co-produção para AmpC e 50% apresentaram mais de um gene para os iniciadores testados. A presença da carbapenemase foi avaliada em amostras bacterianas com susceptibilidade intermediária para ertapenem, através do Teste de Hodge modificado. Os achados do presente estudo caracterizaram a co-produção de AmpC e ESBL, bem como sugerem a necessidade da revisão e a ampliação dos métodos para a detecção de outros padrões de resistência na nossa Instituição.

Cybercrime in general derives from a series of events and factors that converge to foster this phenomenon. After an introduction, the reader will find four chapters. The first one provides a contextualization with background information. The changes in socioeconomic life and the accessibility and reach of the new technologies are assessed. The focus is set on the use of the internet and its far-reaching implications including the responses of national and international institutions. Nowadays, the internet is the window to current affairs whereby the social world is projected, and this idea becomes clear throughout the text. The second chapter deals with factors of patterns of cyberbullying. The third one is concentrated on the impact of cyberbullying and the concept of harm. The final one tackles the possibilities of recovery and resilience. All this allows us to draw some general conclusions. The work ends with a list of references and several annexes that help to understand in depth some of the points discussed throughout the text.

Three enrichment broths and six plating media were compared for efficiency of detection Salmonella in the presence of numbers of Coliforms (10super(5)/ml) and proteus (10super(3)/ml) from artificially inoculated fish samples. Recovery experiments Salmonella anatum, S. typhimurium and S. enteritidis indicated that the two enrichment broths Dulcitol Selinite (DSE) and Selinite Cystine (SC) were equally efficient. Further, the viability of Salmonella, inoculated into fish muscle and kept at 4°C for 48 hours, was found to be not affected by the low temperature storage. Selective plating media like Xylose Lysine Deoxycholate agar (XLD), Brilliant Green Sulphadiazine agar (BGS) and Brilliant Green agar (BG) were found to be superior in performance to Salmonella-Shigella agar: (SS) and Bismuth Sui phite agar (BiS).

Livestock sewage has been utilized for fish culture. There is lack of information on microbiological evaluation and keeping quality of these fishes. This paper reveals the incidence, types of micro-organisms and keeping quality of fishes reared in livestock sewage fed ponds without artificial feed. These fishes revealed microbial incidence and keeping quality comparable to other fishes. Initial mesophilic and psychrophilic counts varied from 3.38 to 5.56 and 2.47 to 4.74. On an average, the counts reduced by about 40% after evisceration and washing. Whole as well as washed fishes had refrigerated (8 ± 1°C) life of not more than 4 days. The average psychrophilic and mesophilic counts of ice (0 to 1°C) stored whole fishes up to 10th day varied from 3.66 to 4.81, 4.61 to 5.24 and in eviscerated and washed fishes 2.17 to 3.69 and 2.78 to 4.41. Both remained acceptable till the 10th day. Qualitative study of surface slime and gills revealed presence of Aerobacter (Enterobacter), Aeromonas, Alcaligenes, Bacillus, Clostridia, E. coli, Klebsiella, Micrococci, Proteus and Pseudomonas.
