The cohesive behaviour of central coordinators in englishContreras Armijo, Jos? Miguel, Gonz?lez Villagra, Fabian Andr?s, Hewstone D?az, Mar?a Loreto, Madrid L?pez, Violeta Susana January 2013 (has links)
Informe de seminario para optar al grado de Licenciado en Lengua y Literatura Inglesa / It is agreed that in order for a stretch of language to constitute a text, it has to form a unified whole (see, for example, Halliday and Hasan, 1976, de Beaugrande and Dressler, 1981,
Martins, 1992). Language cannot be seen as mere units in isolation. The components of
language, whether grammatical,semantic or pragmatic, have to be interrelated and, in actual language use, they always are. It is at this level that the concept of cohesion becomes of paramount importance because it is a supra-sentential phenomenon (Corval?n and Zenteno, 2009). By supra-sentential, we mean that it is a phenomenon whose boundaries go
beyond the sentence and which is related to the meaning conveyed by linguistic units used in combination.

Causal equivalence of framesHenderson, Troy Lee, IV 30 October 2006 (has links)
Frames have recently become popular in the area of applied mathematics known
as digital signal processing. Frames offer a level of redundancy that bases do not
provide. In a sub-area of signal processing known as data recovery, redundancy has
become increasingly useful; therefore, so have frames. Just as orthonormal bases are
desirable for numerical computations, Parseval frames provide similar properties as
orthonormal bases while maintaining a desired level of redundancy. This dissertation
will begin with a basic background on frames and will proceed to encapsulate my
research as partial fulfillment of the requirements for the Ph.D. degree in Mathematics
at Texas A&M University. More specifically, in this dissertation we investigate an
apparently new concept we term causal equivalence of frames and techniques for
transforming frames into Parseval frames in a way that generalizes the Classical Gram-
Schmidt process for bases. Finally, we will compare and contrast these techniques.

Bactericidal activity of an ultra-high dose of gentamicin against gram positive and gram negative bacteria in an in vitro pharmacodynamic modelKoohpayehzadeh Esfahani, Ehsan 01 December 2014 (has links)
Septic shock due to bacterial infections is one of the main causes of death in intensive care units of the developed world. To a great extent, the efforts to improve the outcomes of life-threatening infections including septic shock have focused on the deployment of antimicrobials of ever increasing potency. However, many pathogenic bacterial strains have acquired resistance to available and even recently introduced antibiotics. Alternate pharmacokinetic strategies constitute another pathway to increased antimicrobial efficacy. In this study, we have demonstrated that a single very high dose of gentamicin can eliminate sensitive and moderately resistant bacterial strains at an accelerated rate with a lower risk of regrowth in an in vitro pharmacodynamic model compared to standard (once daily-equivalent) dosing. This approach may be clinically viable if potential toxicity concerns can be addressed.

Previous issue date: 2004 / A mancha-aquosa, causada pela bactéria Acidovorax avenae subsp. citrulli,
é hoje um problema para a cultura do melão nas áreas produtoras do Nordeste,
principalmente nos Estados do Ceará e Rio Grande do Norte. A doença, sobretudo
durante o período chuvoso, chega a dizimar boa parte da produção em algumas
lavouras. Microrganismos têm sido usados no controle de doenças de plantas e o
gênero Bacillus é citado como um dos mais utilizados, devido, em grande parte, à
sua capacidade de produzir substâncias antimicrobianas, entre as quais
lipopeptídeos. O objetivo deste trabalho foi investigar o controle da mancha
aquosa do melão por espécies de Bacillus. Foram realizados testes in vivo,
aplicando-se caldos fermentados de B. subtilis R14, B. megaterium pv. cerealis
RAB7, B. megaterium C116 e Bacillus sp. MEN2, com e sem de células, em
sementes de melão anteriormente inoculadas com A. avenae subsp. citrulli. As
fermentações foram realizadas em mesa agitadora e o plantio das sementes em
bandeja. Testes de antagonismo in vitro foram também realizados pelo método de
difusão em ágar. A avaliação dos testes in vivo foi realizada através das seguintes
variáveis: incidência (INC = porcentagem de plantas com sintomas) e período de
incubação (PI = número de dias transcorridos do plantio até o aparecimento dos
sintomas). A severidade foi avaliada, de acordo com escala de notas, diariamente,
durante cinco dias, calculando-se o índice de doença (IDO) e área abaixo da curva
de progresso da doença (AACPD). Os resultados foram submetidos à análise de
variância e as médias comparadas pelo teste de Tukey. B. subtilis R14, B.
megaterium. pv. cerealis RAB7, B. megaterium C116 e Bacillus sp. MEN2
apresentaram atividade in vitro contra A. avenae subsp. citrulli e controlaram a
doença in vivo, sem diferença significativa entre as quatro linhagens de Bacillus.
Os tratamentos, com e sem células, também não apresentaram diferença
significativa, indicando que a inibição do crescimento do fitopatógeno ocorreu
devido à presença de compostos bioativos produzidos durante as fermentações.
Estes compostos foram parcialmente caracterizados como lipopeptídeos, através
de testes de hemólise e de atividade surfactante

Distribution of a Novel Gram Negative, Capsule-Forming BacteriumHughes, Roxana Bejarano 12 1900 (has links)
A novel Gram negative, capsule-forming bacterium was previously isolated in Dr. G. Roland Vela's laboratory. The distribution of this bacterium in soils from various locations was investigated.
Soil samples from 188 locations around the world were examined. Isolates of the bacterium were obtained from 50 of these soils, with 48 of the isolates found in soils from the southwestern United States and northern Mexico. This suggests that this region is the natural habitat of the bacterium. The other two isolates were obtained from Madrid, Spain and Taipei, Taiwan. None were found in soils from South America or Australia. A lack of variation in morphology and physiological properties in the isolates suggests that a homogeneous population exists, even from widespread geographical locations.
