Current textual studies of Finnegans Wake have identified sigla chiefly as notebook shorthand, but this thesis argues that this interpretation has enforced limitations on future research, owing to the lack of significance mere abbreviation has within literary analysis. The thesis aims to free sigla research from this restrictive critical viewpoint and overturn its present state of neglect in Joyce studies. The research studies the James Joyce Archive and uses a genetic approach. However, instead of its analytical focus being on the notebooks (where the majority of sigla are located), it contains case studies of diagrams from the chapter drafts which are designed using sigla shapes. I have shown the functions of three types of sigla: the first are 'static' (which are shown isolated and not in a relationship to any other characters, which would imply movement); the 'kinetic' status of sigla is a different actualisation of static sigla wherein they are presented in relationships with other sigla or in diagrams which imply their movement within a certain space; and finally the 'three dimensional' sigla are sigla which are brought to the status of a diagram on the basis of parallels between the siglum and meanings of the same shape in the tradition of knowledge. To analyse the narrating quality of a siglum, the minimal condition is that at least one character is in the final version of Finnegans Wake and in a draft drawing. This is the starting point wherein comparisons can be made or symmetries can be established. This process of analysis reveals plotlines and shows how sigla can move within the drawing's space. In conclusion, sigla function as elementary plot units, which develop the plot of Finnegans Wake.

El objetivo de esta tesis es, por una parte, el análisis lingüístico y estadístico de las siglas en el discurso espacializado de los ámbitos de genoma humano y medo ambiente. Por otra parte, el establecimiento de los patrones para el desarrollo de sistemas de reconocimiento semiautomático de siglas tendientes a la creación o mejoramiento de los diccionarios de siglas en línea. Esta investigación se divide en cuatro partes principales, a saber: 1) Definición y tipología de las siglas; 2) análisis estadístico o siglométrico; 3) análisis lingüístico y 4) patrones para la identificación de siglas en corpus. / The aim of this thesis is, on the one hand, the linguistic and statistical analysis of the initialisms in the specialized discourse of the domains of Genomics and Environment. On the other hand, the establishment of patterns to develop semiautomatic recognition systems to facilitate the building or update of online abbreviation dictionaries. This research is divided into four main parts: 1) Initialisms definition and typology; 2) Corpus quantitative analysis; 3) Corpus qualitative analysis, and 4) Initialisms recognition patterns.

In both, the fluxe was 5 sccm (second cubic centimeter), pressure 6 mbar, voltage 490 V and current 0,15A. The objective of work was measure the superficial tension of 100% CO then it treated with plasma, using contact angle measures of water and glycerol with the surface. The samples were tested after treatment, with 8 and 12 months to verify the superficial modification effects. It was verified an increase of hydrophobility with the Sessile drop values varied between 116,69? to 137,85? and it carried on after 12 months. The no treated samples shows contact angle equal 0?. OES analysis and Raman spectroscopy were accomplished. In the SEM analysis was verified oligomers. The plasma treatment is correct environmental, It turning greater than conventional treatments / O tecido 100% Algod?o (CO)* tratado com plasma de metano (CH4) tem aplica??o direta em todas as ?reas que necessitam de um material com maior repel?ncia a solu??es aquosas, como revestimentos e uniformes aplicados a ?rea biom?dica, aeron?utica, automobil?stica, entre outras. Amostras de tecido 100% CO foram tratadas com plasma utilizando duas atmosferas diferentes: g?s CH4, com tempos que variaram de 10 em 10 min. at? 60 min., e uma mistura de metano/arg?nio (CH4/Ar), em propor??es 1:9, 2:8, 3:7, 4:6, 5:5, 6:4, 7:3, 8:2 e 9:1, durante 30 min. O fluxo utilizado nos dois processos foi de 5 cm3/s (cent?metro c?bicos por segundo), a uma press?o de 6 mbar , voltagem de 490 V e corrente de 0,15 A. O objetivo do trabalho foi medir a varia??o da tens?o superficial do tecido 100% CO ap?s tratado com plasma; Utilizando medidas de ?ngulo de contato da ?gua e do glicerol com a superf?cie. As amostras foram testadas imediatamente ap?s o tratamento, com 8 e 12 meses, a fim de verificar a dura??o do efeito desta modifica??o superficial. Verificou-se um aumento da hidrofobicidade atrav?s dos valores do teste da gota s?ssil que variaram entre 116,69? a 137,85? e se mantiveram ap?s 12 meses; As amostras n?o tratadas apresentam ?ngulo de contato igual a 0?. An?lises de espectroscopia de emiss?o ?tica (EEO) e espectroscopia Raman (ER) foram realizadas, bem como, an?lise de microscopia eletr?nica de varredura (MEV) a qual confirmou presen?a de olig?meros. O processo a plasma ? ambientalmente correto e se torna superior em compara??o aos tratamentos convencionais
