The effect of different levels of dietary crude protein on urea metabolism of rusa deer (Cervus timorensis)

Two experiments were conducted to measure urea recycling and rumen flow dynamics in young rusa deer fed low (LP) or high (HP) protein diets. Pool size and flux rate of labelled urea. into and out of the blood pool were measured using single intravenous (i.v.) injection solutions containing [C-14] - and [N-15]-urea. A curve peeling technique was used to fit the enrichment of N-15 or specific radioactivity (SRA) of C-14 to exponential equations. Body urea-N pool size was significantly greater (P < 0.05) when a HP, compared to a LP diet, was fed. Urea space, expressed as a percent of live weight, total flux rate of urea through the blood pool and the irreversible loss of urea was similar for both diets. The mean (+/- S.E.M.) concentration of plasma urea-N was greater when animals were fed the HP diet compared to the LP diet (2 1.1 +/- 0.3 versus 14.4 +/- 1.4 mg/100 ml, respectively). Voluntary feed intake and digestibility of dietary components were also measured. Daily dry matter intakes were not affected by the crude protein (CP) content of the diet, although apparent DM digestibility was significantly greater for HP diet fed in both experiments. An intraruminal infusion of CrEDTA was used to determine rumen flow dynamics. Ruminal mean retention time, relative net outflow rate of water and passage rate constant (k(w)) were significantly greater (P < 0.05) when the HP diet was fed compared to the LP diet. The extent of urea metabolism and flux rates of urea between the blood and secondary pools appear similar to those previously reported for other ruminants fed diets contrasting in CP content.

Using urea dilution to standardise cellular and non-cellular components of pleural and bronchoalveolar lavage (BAL) fluids in the cat

A technique to standardise the analysis of cellular and non-cellular components in epithelial lining fluid (ELF) collected during saline lavage of pulmonary and pleural cavities was developed using the urea dilution method. Bronchoalveolar lavage (BAL) and pleural lavage (PL) fluids were collected from 12 clinically healthy cats. Total and differential cell counts in BAL fluid were within normal ranges for the cat, while cell Counts in PL fluid were assumed to be normal based on clinical health during examination, auscultation and lactate dehydrogenase (LDH) activities being comparable with other species. The major clinical implication of this study was that nucleated cell counts within feline ELF could not be predicted from analysis of lavage fluid which suggests that calculation of the proportion of ELF in lavage fluid by the urea dilution method may be necessary to avoid misdiagnosis of health or disease in pulmonary or pleural cavities.

AVALIAÇÃO COMPARATIVA ENTRE AGRADABILIDADE FACIAL, PROPORÇÃO ÁUREA E PADRÃO FACIAL

O propósito desta pesquisa foi estudar algumas análises faciais utilizadas para diagnóstico ortodôntico e verificar a concordância entre norma lateral e frontal na avaliação da agradabilidade facial para os grupos leigos e profissionais, a concordância entre estes grupos na avaliação da agradabilidade facial nas normas lateral e frontal, bem como verificar a associação entre agradabilidade facial e Proporção Áurea, agradabilidade facial e Padrão Facial e entre Padrão Facial e Proporção Áurea. Utilizou-se 208 fotografias faciais padronizadas (104 laterais e 104 frontais) de 104 indivíduos escolhidos aleatoriamente, que primeiramente foram classificadas em agradável , aceitável e desagradável por dois grupos distintos: grupo Ortodontia e grupo Leigos . As fotografias laterais e frontais foram submetidas a medidas de Proporção Áurea Facial por meio de programa computadorizado e os indivíduos foram classificados quanto ao Padrão Facial pelo seu aspecto lateral. Após análise estatística, verificou-se que não houve concordância entre as variáveis da avaliação de agradabilidade estudadas, bem como não houve associação entre Proporção Áurea com agradabilidade facial ou com Padrão Facial. Entre agradabilidade facial e Padrão Facial, observou-se para a norma lateral associação fortemente positiva, porém para a frontal não houve associação para ambos os grupos de avaliadores.

Revaloracion de la comedia de Pedro Munoz Seca: Un teatro menospreciado

The comedies of Pedro Muñoz Seca (1879-1936) received extraordinary public acclaim for over thirty years, yet critics rejected them. Although several experts have recently begun to study his plays in an objective manner, this author has generally either been underrated or omitted from theater histories. This study identifies the merit, contributions and relevance of Muñoz Seca's works so that the unwarranted void that now exists in Spanish theater annals is justly filled. Historical and biographical backgrounds and a brief sketch of the development of comedy in Spain serve to introduce the literary, political and social contexts in which the author develops the subgenre known as "astracán" and introduces the "fresco" character type. ^ This analysis illustrates Muñoz Seca's verbal comic techniques---the use of regional dialects and individuals' speech peculiarities, double entendres, incongruence, periphrasis, and ingenious plays on words. It also explores the author's profound theatrical sense manifested in inter-textual references and self-reflexivity within the content of his plays. In addition, it identifies the scenic creativity he displays through the use of cinematography, the removal of color from stage decor (or the elimination of scenery altogether), and the original application of music to create comic effect. Furthermore, this study comments the satirical tone projected in Muñoz Seca's characters' idiolect and barbarisms as socio-political conditions worsen. Finally, it brings forth the author's use of parody to criticize his society and to deride other theatrical genres in vogue during his time. ^ While the polarization between Muñoz Seca's popular success and the critics' rejection can be explained by esthetic and ideological prejudices, this dissertation ascertains that the true nature of the author's plays has not been properly identified. The "astracán" is a double parody; however, since it caricaturizes a comic subgenre that is already burlesque, its defining parodic features have been consistently misinterpreted as mere exaggerations and defects. What is more, as its critical content is not recognized, its renewing function goes unnoticed. Muñoz Seca's "astracán" illustrates an era of the Spanish comic stage and paves the way for the theater of the absurd. Its merit and relevance must be recognized. ^

El objetivo del presente estudio fue relacionar los componentes de la proporción áurea con el parámetro facial de estudiantes de odontología en una universidad de la provincia de Chiclayo, 2014. El diseño del estudio fue transversal, descriptivo y prospectivo. La población de estudio fue representada por 88 estudiantes de una Escuela de Odontología, se diseñó una ficha de recolección según las medidas antropométricas craneofaciales. Se capacitó y se evaluó la estabilidad de la concordancia intra e interexaminador de los investigadores gracias a la participación de un Especialista en Ortodoncia, a fin de lograr una estandarización en las mediciones, verificado mediante una prueba T para muestras pareadas. Se encontró que el 65.91% del total de pacientes presentaban proporción áurea en su dimensión externa, 48.86 % son braquifaciales, 13.64 % mesofaciales, 3.41 % dolicofaciales Se encontró que el 57.95% del total presentaban proporción aurea en su relación vertical, 42.05% son braquifaciales, 10.23 % mesofaciales y 5.68% dolicofaciales. En cuanto al perfil armónico, el 70.45% del total de pacientes no presentan proporción áurea, de los cuales el 53.41% son braquifaciales, 10.23 % son mesofaciales y 6.82% son dolicofaciales. Para el contraste de la hipótesis se utilizó el coeficiente de correlación Chi cuadrado. Para todas las pruebas estadísticas el nivel de significancia fue de <5% (p<0,05) con un 95% de nivel de confiabilidad. Se concluyó que sólo existe relación significativa entre el componente dimensión externa de la proporción áurea y el parámetro facial de los estudiantes de odontología en una universidad de la provincia de Chiclayo.

Synthesis of waterborne polyurethane-urea dispersions with chain extension step in homogeneous and heterogeneous media

Hypothesis: The possibility of tailoring the final properties of environmentally friendly waterborne polyurethane and polyurethane-urea dispersions and the films they produce makes them attractive for a wide range of applications. Both the reagents content and the synthesis route contribute to the observed final properties. Experiments: A series of polyurethane-urea and polyurethane aqueous dispersions were synthesized using 1,2-ethanediamine and/or 1,4-butanediol as chain extenders. The diamine content was varied from 0 to 4.5 wt%. Its addition was carried out either by the classical heterogeneous reaction medium (after phase inversion step), or else by the alternative homogeneous medium (prior to dispersion formation). Dispersions as well as films prepared from dispersions have been later extensively characterized. Findings: 1,2-Ethanediamine addition in heterogeneous medium leads to dispersions with high particle sizes and broad distributions whereas in homogeneous medium, lower particle sizes and narrow distributions were observed, thus leading to higher uniformity and cohesiveness among particles during film formation. Thereby, stress transfer is favored adding the diamine in a homogeneous medium; and thus the obtained films presented quite higher stress and modulus values. Furthermore, the higher uniformity of films tends to hinder water molecules transport through the film, resulting, in general, in a lower water absorption capacity.

Del texto a los contextos: ejemplos de interpretación alegórica y horizontes culturales en algunos comentarios a la "Divina Comedia" entre los siglos XIV y XV

El presente trabajo realiza un estudio sobre los comentaristas de la Divina Comedia del siglo XIV y algunos del XV, examinando su papel como intérpretes del poema dantiano tanto desde el punto de vista literario como histórico e ideológico en el momento de transición de la Edad Media al Humanismo, tomando en cuenta las señales que de esta evolución se van encontrando ya en los comentarios inmediatamente posteriores a la muerte de Dante. Uno de los aspectos que faltaba tratar en la historia de los estudios era un trabajo comparativo sobre el modo de conocimiento de todos y cada uno de los más importantes comentaristas antiguos por lo que concierne las alegorías y el método hermenéutico utilizado. Así el análisis interpretativo en los comentarios antiguos de algunas de las alegorías más conocidas, pero también muy controvertidas, como las tres fieras y el contrapasso, ha sido el punto de partida para el presente trabajo. Se ha optado por hacer “hablar” a los comentaristas a través de un acercamiento al texto lo más directo posible, sin tomar posiciones críticas predefinidas, para favorecer un acercamiento al texto de una manera lo más filológicamente neutral...

Análisis comparativo de traducciones comercializadas de productos multilingües. Doblaje español de la comedia de situación Modern Family

El presente Trabajo de Fin de Grado consiste en el análisis comparativo de la traducción para doblaje (del inglés al español) de un producto audiovisual multilingüe en el que existe una coincidencia entre la lengua 2 y la lengua 3: la comedia de situación estadounidense Modern Family. El multilingüismo que caracteriza al objeto de estudio tiene su origen, en la mayoría de los casos, en el personaje de Gloria Pritchett, que además de la lengua 1 de la serie (el inglés) utiliza con frecuencia su lengua materna (el español). Para el corpus de este trabajo se han seleccionado diez episodios de diferentes temporadas de la serie y se han extraído, mediante una herramienta informática de edición de vídeo, las escenas que presentaban situaciones multilingües. La versión original y la versión doblada al español de dichas escenas han sido transcritas en tablas bimodales en un documento MS Word para facilitar su análisis. El estudio comparativo de este trabajo se apoya principalmente en las técnicas de traducción de productos audiovisuales multilingües que propone de Higes (2014: 113-114) y las nociones de traducción del humor que ofrece Zabalbeascoa (2001: 258); todo recogido en el marco teórico de este TFG. No ha sido posible incluir la totalidad del corpus analizado (unas 5000 palabras) dado el límite de extensión de este trabajo. No obstante, se ha considerado oportuno incluir los fragmentos más significativos como ejemplo de las técnicas de traducción que han sustentado las observaciones realizadas en el cuerpo del análisis. Por último, se ha procedido a plasmar las conclusiones que se han podido extraer del análisis comparativo del corpus seleccionado, en las que se ofrece una breve recapitulación de las principales dificultades que presenta la traducción para doblaje de la serie objeto de estudio y de las técnicas de traducción a las que se ha recurrido con mayor frecuencia.

Utilization of nitrogen (15N) from urea and green manures by rice as affected by nitrogen fertilizer rate.

The use of green manures (GMs) in combination with nitrogen (N) fertilizer application is a promising practice to improve N fertilizer management in agricultural production systems. The main objective of this study was to evaluate the N use efficiency (NUE) of rice plant, derived from GMs including sunn hemp (Crotalaria juncea L.), millet (Pennisetum glaucum L.) and urea in the greenhouse. The experimental treatments included two GMs (sunn hemp-15N and millet-15N), absence of N organic source (without GM residues in soil) and four N rates, as urea-15N (0, 28.6, 57.2 and 85.8 mg N kg-1). The results showed that both rice grain and straw biomass yields under sunn hemp were greater than that of millet or without the application of GM. The NUE of rice under sunn hemp was greater than that under millet (18.9 and 7.8% under sunn hemp and millet, respectively). The urea N application rates did not affect the fertilizer NUE by rice (53.7%) with or without GMs. The NUE of GMs by rice plants ranged from 14.1% and 16.8% for root and shoot, respectively. The study showed that green manures can play an important role in enhancing soil fertility and N supply to subsequent crops.
