Este trabalho foi desenvolvido com o objetivo de processar a berinjela (Solanum melongena L.) utilizando técnicas combinadas de desidratação osmótica e secagem convectiva, visando à obtenção de um novo produto para a indústria alimentícia. As fatias de berinjela “in natura’’, osmodesidratado e secas foram caracterizadas quanto aos parâmetros físico-quimicos (sólidos solúveis totais, cinzas, sólidos totais, acidez total titulável, pH e sódio), físico (teor de água, atividade de água, cor e textura) e químico (minerais). As fatias de berinjela “in natura” se apresentaram pouco ácidas, com o pH bem mais próximo do neutro em comparação às fatias de berinjela osmodesidratada e secas, com predominância do aumento no teor de cinza ao decorrer do processo. A melhor condição de processo encontrada para a desidratação osmótica das fatias de berinjela foi na temperatura de desidratação osmótica 30 °C; 3% da concentração de NaCl e tempo de imersão de 120 min. A secagem convectiva foi realizada em secador de bandejas nas temperaturas de 50, 60 e 70 ºC, com velocidade do ar de 1,2 m/s. Os dados experimentais obtidos na secagem proporcionaram a avaliação das curvas de secagem, às quais foram ajustadas segundo os modelos de Page, Henderson e Pabis, Lewis, Midilli e Cavalcanti Mata. Os modelos de Midilli e Cavalcanti Mata foram os que melhor se ajustaram à de cinética de secagem das fatias de berinjela osmodesidratadas. As microestruturas das fatias de berinjelas sem desidratação e também as fatias osmodesidratadas e secadas a 70 °C foram analisadas por microscopia eletrônica de varredura, onde foi possível observar que a combinação de processos nas fatias de berinjela provocou uma maior destruição das estruturas celulares, bem como uma maior desorganização das células, resultado do colapso, tornando-se um produto tipicamente amorfo. A amostra de conserva de berinjela osmodesidratada (azeite, pimenta calabresa, salsa e alecrim), obteve maior aceitação em relação a aparência, aroma, cor, sabor e textura das amostras de conservas de berinjela superiores às demais amostras de conservas.
This work was developed with the objective of processing the eggplant (Solanum melongena L.) using combined techniques of osmotic dehydration and convective drying, aiming at obtaining a new product for the food industry. The "in natura" eggplant slices, dried and dried were characterized as physical-chemical parameters (total soluble solids, ash, total solids, titratable total acidity, pH and sodium), physical (water content, water activity, color and texture) and chemical (minerals). The slices of eggplant "in natura" presented little acid, with the pH much closer to the neutral one compared to the slices of eggplant, the dried and dried, with predominance of the increase in the ash content in the course of the process. The best process condition found for osmotic dehydration of eggplant slices was at the osmotic dehydration temperature 30 ° C; 3% NaCl concentration and immersion time of 120 min. The convective drying was carried out in a tray dryer at temperatures of 50, 60 and 70 ºC, with air velocity of 1.2 m / s. The experimental data obtained in the drying provided the evaluation of the drying curves, which were adjusted according to the models of Page, Henderson and Pabis, Lewis, Midilli and Cavalcanti Mata. The models of Midilli and Cavalcanti Mata were the ones that best fit the drying kinetics of eggplant slices. The microstructures of slices of eggplants without dehydration and also the slices modified and dried at 70 ° C were analyzed by scanning electron microscopy, where it was possible to observe that the combination of processes in the eggplant slices caused a greater destruction of the cellular structures, as well as a greater disorganization of the cells, resulting from the collapse, becoming a typically amorphous product. The sample of preserved eggplant (olive oil, chilli pepper, parsley and rosemary) was more widely accepted for the appearance, aroma, color, flavor and texture of the eggplant preserves samples than the other canned samples.

Full textTernary codes for unequal error protection is a part of a communication system where different parts of the information to be transmitted can receive different amount of error protection. There are a lot of applications where the channel conditions fluctuate so that reliable or acceptable communication can not be guaranteed. Regardless whether the fluctuations of the channel are intentional or not the idea is to let the coderate decrease so that the error correcting capability can increase for the part of the information to be more protected.
By using the support, the nonzero positions of the ternary code, a new binary code can be extracted with properties different from the ternary code in the sense of cardinality and minimum Hamming distance. When the channel conditions are good the receiver decodes the message using ternary decisions and receives all information included in the codeword. When the channel conditions drops the receiver decodes the message using binary decisions to assimilate the information in the support. What the properties of the ternary code should be like to give a good ternary error correcting capability and best possible error correcting capability for the support is one of the questions this thesis will look at. A number of ternary codes used in this thesis are constructed from Mattias Svanströms dissertation “Ternary Codes with Weight Constraints”, [4]. The properties of the support have been studied and modified in that sense it has given a new binary code with better error correctingcapability and an acceptable coderate.
The unequal error protection lies in the modulation scheme. By using knowledge of the weight distribution and the error correcting capability of the ternary code the signal points in the modulation scheme can be optimized in the sense of error probability for ternary or binary decoding. When optimal error probability for the complete system is required optimal signal points for both modulations schemes needs to be considered and the final signal points placed thereafter.

Full textENGLISH ABSTRACT: Subdivision is an important and e cient tool for rendering smooth curves and surfaces in computer graphics, by repeatedly applying a subdivision (re ning) scheme to a given set of points. In the literature, attention has been mostly restricted to developing binary subdivision schemes. The primary emphasis of this thesis is on ternary subdivision, and in particular on the interpolatory case. We will derive a symmetric ternary interpolatory subdivision scheme for the rendering of curves, satisfying analogous properties to the Dubuc-Deslauriers binary scheme. Explicit construction methods, as well as a corresponding convergence analysis, will be presented. Graphical illustrations of the results will also be provided.

Full textThis work aims to analyze the novel João Ternura, by Aníbal Machado, in relation to the contradictions between the ideological project of early Brazilian Modernism and the problems of the national historical process. When he starts writing his only novel, in 1926, Aníbal Machado shares the libertarian goals and ideological assumptions of the Brazilian artistic avant-garde. However, as the novel continues to be written until 1964, the year of the military coup, its very form and style document the collision between the narrative material and the national historical process around it. These conflicts culminate in a process of dissolution that condemn both the novel and its protagonist to a state of inconclusiveness. Analyzing João Ternura brings to light reflections on the possibilities of Brazilian formation as an autonomous and independent nation

Full textIn this work the synthesis of MgCdS ternary semiconductor nanocrystal alloys has been carried out by aqueous route through a bottom-up approach, using conventional hydrothermal heating as well as in situ onto graphene matrices. In the synthesis of MgCdS nanocrystals, the effect of each reaction parameter on the spectroscopic properties was studied aiming to understand the possibilities to control the optical properties. Emission spectra of MgCdS samples obtained in the experiments designed to optimize reaction parameters exhibited a single emission band reflecting nanocrystal growth, with quantum yields as high as 85%. Based on the presence of two bands in absorption spectra as well as atomic absorption spectrometry (AAS) data it was possible to propose that nanocrystals are composed of Cd and Mg. Concerning the structural architecture, it has been proposed that nanocrystals show a core-shell structure with a diffuse interface. Data from AAS also showed that the final composition of nanocrystals is generally different from the initial reaction Cd:Mg proportion, as the metal precursors have distinct reactivities. Morphological analyses by transmission electron microscopy (TEM) of nanocrystals evidenced the predominance of spherical shapes and sizes below 4 nm. Studies of the formation of nanocrystal alloys with Mg1-xCdxS and Cd1-xMgxS composition, by ion exchange from the binary components MgS and CdS helped the discussion of spectroscopic behavior of the ternary system MgCdS. It was possible to confirm that the introduction of a second cation (Cd2+ or Mg2+) into each binary structure (MgS or CdS) is consistent with the observation of two absorption bands and only one emission band. The addition of graphene derivatives during the synthesis of MgCdS nanocrystals was carried out aiming to improve the properties of the materials, as well as providing a physical support to the nanocrystals, favoring future applications. The presence of graphene induced shifts in the emission bands to larger wavelengths concomitant with intensity reduction, which can be taken as evidence of interactions between the materials. The morphologies of composites were characterized by typical graphene sheets decorated with spherical nanocrystals.
Neste trabalho foram realizadas as sínteses de nanocristais (NCs) semicondutores ternários de MgCdS via síntese aquosa através da metodologia bottom-up, assistida por tratamento térmico hidrotermal convencional, além da síntese in situ de nanocompósitos de MgCdS em matrizes de grafeno. A síntese do nanocristal de MgCdS foi avaliada através do efeito da variação de cada parâmetro de síntese sobre as propriedades espectroscópicas do material, a fim de se compreender as possibilidades de controle das propriedades ópticas. Os espectros de emissão dos NCs de MgCdS, referente ao estudo de otimização dos parâmetros de síntese, apresentaram uma única banda de emissão intensa que reflete o crescimento do nanocristal, com rendimentos quânticos de fotoluminescência elevados, chegando a 85%. Com base na presença de duas bandas de absorção no espectro de UV-visível, bem como de dados de espectrofotometria de absorção atômica (AAS), pode-se inferir que os nanocristais são compostos pelos metais de Cd e Mg, propondo-se a hipótese de uma arquitetura caroço-casca com interface difusa. Os dados obtidos através de AAS mostraram também que, como os precursores tem reatividades distintas, a composição dos materiais formados tende a diferir da proporção Cd2+:Mg2+ utilizada na reação. As análises morfológicas realizadas por microscopia eletrônica de transmissão (TEM) permitiram verificar o contorno esférico e uniforme das nanoesferas e estimar o tamanho dos nanocristais, sendo abaixo de 4 nm. Estudos de formação de ligas do tipo Mg1-xCdxS e Cd1-xMgxS, por troca iônica a partir dos componentes binários MgS e CdS permitiram compreender melhor os dados espectroscópicos dos nanocristais formados introduzindo ambos precursores simultaneamente. Confirmou-se que a introdução do segundo cátion (Cd2+ ou Mg2+) em cada estrutura binária (MgS ou CdS) de fato causa a formação de duas bandas de absorção e somente uma de emissão. A implementação de derivados de grafeno na síntese do MgCdS foi realizada a fim de aprimorar as propriedades gerais do material, bem como de propiciar um suporte físico aos nanocristais de MgCdS, favorecendo aplicações. A presença do grafeno na síntese do nanocristal proporcionou deslocamento da banda de emissão para maiores comprimentos de onda com redução da intensidade luminescente, evidenciando interações entre os materiais. As morfologias dos compósitos apresentam folhas de grafeno decoradas com nanocristais esféricos.

Full textLa asfixia fetal tiene como consecuencia una disminución de la oxigenación, lo que genera un descenso del aporte sanguíneo en los órganos que no son imperativos para la sobrevivencia inmediata, donde comienza a emplearse la glicólisis anaeróbica para producir energía. Esta vía metabólica es menos eficiente, debido a que la energía producida es reducida y las reservas de carbohidratos son rápidamente agotadas, desarrollándose finalmente una acidosis metabólica por la acumulación de acido láctico. Esta ha sido asociada con disminución de la absorción de inmunoglobulinas y falla en la transferencia de inmunidad pasiva. El objetivo de este estudio fue evaluar la relación entre la lactatemia de terneras neonatas, con la concentración de PST y la predisposición a enfermar durante su primer mes de vida. Se realizó entre mayo y agosto de 2014 en una lechería de la zona central e incluyó a 38 terneras Holstein-Friesian. Se tomaron muestras de sangre para medir el lactato sanguíneo con un analizador portátil y estimar las PST por refractometría. Además se registraron los eventos clínicos producidos durante el primer mes de vida. La comparación estadística entre las medias de los parámetros evaluados se realizó con la prueba t de Student. Se relacionó el lactato con las PST por medio de análisis de regresión y se evaluó la habilidad predictiva de la lactatemia en la morbilidad de las terneras con análisis de ROC. Terneras provenientes de distocias tenían mayores concentraciones de lactato sanguíneo (p<0,1) y menores niveles de PST (p<0,05), que terneras nacidas de partos eutócicos. Las terneras que enfermaron presentaron mayores concentraciones de lactato, en comparación con las terneras sanas (p<0,05). No hubo diferencias significativas entre las concentraciones de PST entre sanas y enfermas. Si bien el lactato sanguíneo y las PST evidenciaron una asociación negativa (p<0,1), no hubo una relación estadística entre ambos parámetros baja (r2=0,1). El análisis ROC demostró que la medición de la lactatemia posee cierto valor predictivo de enfermedades, con un punto de corte de 4,5 mmol/l para distinguir entre terneras sanas y aquellas que tienen más probabilidades de enfermar. Por lo tanto, el uso de analizadores portátiles de lactato sanguíneo, constituye una herramienta útil para ser usada en terreno en la detección temprana de terneras con una mayor susceptibilidad de enfermar

As the demand of sustainable energy technologies increases in recent years, thermoelectric materials can potentially become a solution by increasing energy efficiency in certain systems, such as waste heat recovery system. Skutterudites is a popular group of thermoelectric materials because they show low thermal conductivity with filled voids in their structures. To investigate the potential of ternary skutterudites as thermoelectric materials, first-principles calculations are performed on filled and unfilled CoSn1.S1.S5, CoSn1.5Se1.5, CoSn1.5Te1.5, CoGe1.5S1.5, CoGe1.5Se1.5, and CoGe1.5Te1.5. Alkaline-earth metal and Lanthanum are used as void fillers in this study. Transport properties, including Seebeck coefficient and electrical conductivity, are obtained from Boltzmann transport theory. The calculation results show high Seebeck coefficients and low electrical conductivities. Future work will focus on increasing the electrical conductivity while reducing the thermal conductivity with appropriate filling.

This work aimed to utilize the combined osmotic dehydration and convective drying process to obtain eggplant chips by a non-conventional healthier and more low cost way. The combined process was studied through a factorial experimental design having as independent variables the temperature (30-50°C), sucrose (27,5 to 42,5% w/w) and sodium chloride (3,75 to 6,25% w/w) solution concentrations and immersion time (142,5 to 247,5 min.). The dependent ones were the water loss (PA), sucrose gain (GSac), sodium gain (GSódio), and the GSac/GSódio ratio. Samples from each osmotic condition were dried at 60°C for 4 hours in a convective dryer with a 1m/s air velocity. The objective was to obtain a maximum water loss with a minimum sucrose and sodium impregnation. Statistic models were well fitted according to the Response Surface Methodology. Once PA was above 90% and water activity was less than 0,4 for all samples, it was used the GSac/GSódio ratio as a parameter for choosing the best process condition which should be maximum. Thus, from this analysis, the best way to obtain eggplant chips was at 50°C, with a sucrose and sodium chloride concentrations of 45% and 7,5%, respectively, for 127,5 minutes. This independent variables combination led to a final product with its sodium content sensory attenuated due the sucrose presence and based on this point of view, it could be considered a healthier product compared with similar commercial, as well as by non-use of conventional frying process.
O presente trabalho teve como objetivo a utilização da tecnologia combinada de desidratação osmótica e secagem para obtenção de berinjela seca em forma de chips , de modo a aproveitar esta matéria-prima e obter um produto final, por vias não convencionais, mais saudável e de baixo custo. O processo de desidratação osmótica seguida de secagem convectiva foi realizado através de um delineamento experimental, tendo como variáveis independentes a temperatura (30 50°C), concentração de sacarose (27,5 42,5% p/p) e concentração de cloreto de sódio (3,75 6,25% p/p) da solução osmótica e o tempo de imersão (142,5 247,5 min.), e como variáveis dependentes PA, GSac, GSódio, GSac/GSódio e aw, secas numa temperatura e tempo de 60°C e 4 horas, respectivamente, a uma velocidade de 1m/s, onde o objetivo foi obter uma máxima perda de água com uma mínima incorporação de sacarose e sódio. Foram ajustados modelos de primeira ordem segundo a metodologia de superfície de resposta. Uma vez que PA foi acima de 90% e a aw foi menor que 0,4 para todos os ensaios, utilizou-se como parâmetro de escolha da melhor condição do processo, a análise do agente osmótico, mediante a razão GSac/GSódio, a qual deveria ser máxima, segundo a composição de amostras de batata chips comerciais. A condição ideal para obtenção de berinjela seca em forma de chips foi T=50ºC, CSac=45%, CSal=7,5%, t=127,5 minutos, onde tal fato implica em um produto final com um teor de sódio sensorialmente atenuado devido à presença da sacarose e sendo considerado, portanto, mais saudável em função dos menores teores de sódio e sacarose, quando comparado com os similares comerciais, assim como também, pela não utilização do processo de fritura convencional.

Introducing itself by means of a language loaded with significance and punctuated by marks of oppression and exclusion, African-Brazilian literature, by conveying the word, ensures the black community breaking a silence for a long time by the subjugation and subservience proportioned by enslavement. Such texts increasingly affirm themselves in the scenery of the Brazilian literary canon, when they turn to the way of the fights that impel the black population to seek for their personal affirmation and for the guarantee of their rights as citizens. Under this angle we´ll analyze here the works A cor da ternura (1998), by Geni Guimarães and Ponciá Vicêncio (2003), by Conceição Evaristo, in a comparative study of the protagonist´s discourses in what concerns the issues of identity, presented through a plot of memoirs in which the life experiences exposed by them suggest actions of combat against and resistance to racial prejudice and oppression on the part of the dominant society. In this work we use as theoretical basis the studies made by Anna Freud (1976); Halbwachs (1990); Bergson (1999); Landowski (2002); Giddens (2002); Bauman (2005); Seligmann-Silva (2005); Hall (2006/2013); Fanon (2008); (2010); Castells (2010) and Candau (2012), among others.
Apresentando-se por meio de uma linguagem carregada de significados, marcas de opressão e exclusão, a literatura afro-brasileira, através da veiculação da palavra, garante a comunidade negra o rompimento de um silêncio pontuado pela subjugação e subserviência advindas da escravização. Tais textos cada vez mais se firmam no panorama das letras brasileiras ao enveredar pelos caminhos das lutas que impulsionam a população negra em busca da sua afirmação pessoal e da garantia de seus direitos enquanto cidadãos. Sob este viés analisamos aqui as obras A cor da ternura (1998), de Geni Guimarães e Ponciá Vicêncio (2003), de Conceição Evaristo, por meio de uma pesquisa bibliográfica constituída por um estudo comparatista dos discursos das protagonistas quanto às questões identitárias, apresentadas por meio de um enredo memorialístico, em que as vivências por elas expostas sugerem ações de combate e resistência à discriminação e à opressão por parte da sociedade dominante. Neste trabalho utilizamos como aporte teórico os estudos de Anna Freud (1976); Halbwachs (1990); Bergson (1999); Landowski (2002); Giddens (2002); Bauman (2005); Seligmann-Silva (2005); Hall (2006/2013); Fanon (2008); (2010); Castells (2010) e Candau (2012), dentre outros.

Full textLa diarrea neonatal (DN) es la patología más frecuente y la primera causa de muerte en terneros, generando altas pérdidas en la industria. Los tratamientos más utilizados incluyen el uso de antibióticos de amplio espectro. El uso de antibacterianos específicos podría contribuir al control de esta patología. El objetivo del presente estudio fue evaluar el efecto de un producto comercial formulado a base de bacteriófagos específicos para el control de E.coli y Salmonella spp., sobre la presentación de DN y peso al destete en terneras Holstein de la zona central de Chile. Para ello, se trabajó en dos lecherías comerciales ubicadas en las regiones de Valparaíso y Metropolitana, donde se asignaron aleatoriamente 80 terneras recién nacidas a dos grupos en cada predio, un grupo control y un grupo experimental. El grupo experimental recibió 0,5 gramos de un controlador microbiológico (Milkeeper S®, Phage Technologies, Santiago, Chile) a base de bacteriófagos específicos contra E. coli, Salmonella panama, S. dublin, S. mbandaka y S. typhimurium, disueltos en la leche o sustituto, dos veces al día hasta el destete. El grupo control recibió, 0,5 gramos de un placebo a base de almidón disuelto en la leche o sustituto, dos veces al día hasta el destete. Se evaluó en cada ternera el peso al nacimiento, proteínas séricas totales (PST) entre el 3er a 5to día de vida, peso a los 30, 60 y 75 días aproximadamente, como también se registraron los casos de enfermedad y muertes. Las incidencias de diarrea no fueron diferentes (p=0,79) entre el grupo control (50%) y el grupo experimental (42,5%). Tampoco se observaron diferencias en la mortalidad registrada en el periodo, siendo de 7,5% en el grupo control y de 5% en el grupo experimental. Por otro lado, la duración de los cuadros fue significativamente menor (p=0,03) en las terneras tratadas con el bacteriófago (5,9±1,81 días) que en el grupo control (8,5 ± 4,24 días) y se observó una tendencia a una menor severidad de las diarreas en las terneras tratadas. Las terneras del grupo experimental tuvieron una tendencia a una mayor ganancia diaria de peso que las del grupo control (628gr/día y 578gr/día, respectivamente; p=0,07), y un mayor peso al destete que las del grupo control (82,0 kg y 78,0 kg, respectivamente; p=0,03). Se concluye que el producto testeado no disminuye en forma significativa la incidencia de DN en terneras, pero sí la duración y la severidad de estas, mejorando significativamente el peso al destete.
The neonatal diarrhea (ND) is the most common disease and the main cause of death in calves, generating high losses in the industry. The most widely used treatments include the use of broad-spectrum antibiotics. The use of specific antibacterials could help to control this disease. The aim of this study was to evaluate the effect of a commercial product formulated with specific bacteriophages for control of E. coli and Salmonella spp., on the presentation of ND and weaning weight in Holstein calves of central Chile. The study was conducted in two commercial dairies located in Valparaiso and Metropolitan regions, where 80 newborn calves were randomly assigned to two groups on each farm, a control group and an experimental group. The experimental group received 0.5 grams of a microbiological controller (Milkeeper S®, Phage Technologies, Santiago, Chile) based on specific bacteriophages against E. coli, Salmonella panama, S. dublin, S. Mbandaka and S. typhimurium, dissolved in milk or substitute, twice a day until weaning. The control group received 0.5 grams of a placebo based on starch dissolved in the milk replacer, twice a day until weaning. Birth weight, total serum protein (TSP) from the 3rd to 5th day of life, weight at about 30, 60 and 75 days, and illness and deaths frequencies were also registered. The incidences of diarrhea were not different (p = 0.79) between the control group (50%) and the experimental group (42.5%). No differences were observed in mortality rates during the period, with 7.5% in the control group and 5% in the experimental group. On the other side, the duration of the episodes of diarrhea was significantly lower (p = 0.03) in calves treated with bacteriophage (5.9 ± 1.81 days) than in the control group (8.5 ± 4.24 days ) and a trend toward a lower severity of diarrhea in treated calves was observed. The calves of the experimental group had a trend to greater daily weight gain than the control group (628gr / day and 578gr / day, respectively; p = 0.07), and increased weaning weight than the control group (82.0 kg and 78.0 kg, respectively; p = 0.03). It is concluded that the tested product does not significantly decrease the incidence of DN in calves, but affects the duration and severity of that, significantly improving weaning weight.

Full textEn el marco de la falta de información sobre la fermentación ruminal de terneros jóvenes alimentados con dietas concentradas nos planteamos los siguientes objetivos:
a) Caracterizar la fermentación ruminal y la degradabilidad de la proteína de suplementos vegetales durante todo el engorde.
b) Estudiar los efectos de la sincronización de la degradabilidad ruminal del almidón de la cebada y el maíz con dos fuentes proteicas, sobre la fermentación ruminal y sobre los parámetros productivos y el comportamiento de ingestión.
En el primer experimento con un diseño de medidas repetidas estudiamos como evolucionaba la fermentación ruminal y la degradación de la proteína de 4 suplementos vegetales (dos leguminosas y dos subproductos de la extracción de aceite) en 6 terneras en crecimiento entre los 80 y los 250 kg alimentadas con dietas concentradas con distinta proporción de fibra. Una dieta contenía un 12% de paja de cebada y la otra un 30% de alfalfa deshidratada, y ambas eran isoenergéticas e isoproteicas. Observamos que aunque en ambas dietas la actividad celulolítica, estimada a través de la degradación ruminal de la FND de una muestra de heno de alfalfa incubada in situ, era muy baja, fue ligeramente superior en la dieta que tenía mayor proporción de forraje. La dieta con un 30% de alfalfa deshidratada también presentó mayor degradabilidad ruminal de las dos leguminosas grano (guisante y altramuz) incubadas in situ. Con la edad aumentó la ingestión total de carbohidratos no fibrosos y la fermentación se volvió más amilolítica y proteolítica, aumentando la concentración de AGV totales, la proporción de propionato y la degradabilidad efectiva de la proteína de los suplementos incubados, a excepción de la harina de soja. Estas mismas dietas se administraron en el segundo experimento a 4 terneras de 300 kg de peso vivo, asignadas a un diseño de cross-over para estudiar el efecto del nivel de fibra de la dieta sobre la fermentación ruminal y la degradación proteica de 7 suplementos proteicos de origen vegetal en la última fase de engorde. El perfil de fermentación ruminal no se vio afectado por el nivel de fibra de la dieta, siendo un perfil básicamente amilolítico. La degradación de la FND del heno de alfalfa también fue muy baja (25,5%) y la degradación de las leguminosas grano fue más baja que los valores aportados por los sistemas de referencia, siendo los valores obtenidos más adecuados para estas condiciones de producción. Los valores de degradación de la harina de soja y la harina de girasol fueron similares a los aportados por las tablas de referencia, sin verse afectados por el nivel de fibra de la dieta.
Para el estudio de la sincronización de la degradabilidad ruminal entre fuentes de energía y de proteína, combinamos la cebada y el maíz con dos fuentes proteicas, harina de soja y harina de girasol, que demostraron tener diferente velocidad de degradación ruminal en los experimentos 1 y 2. De estas combinaciones resultó una dieta sincronizada para una fermentación rápida (cebada-girasol); una dieta sincronizada para una fermentación lenta (maíz-soja) y dos dietas desincronizadas con un componente de fermentación rápida y uno de fermentación lenta (cebada-soja y maíz-girasol). Las 4 dietas eran isoproteicas e isoenergéticas y con una relación forraje:concentrado cercana a 10:90. In vitro, con el sistema de fermentadores de doble flujo continuo observamos una potenciación de la fermentación ruminal por efecto de la sincronización, sin que se viera afectada por el pH ruminal que se mantuvo constante a 6,2 o fluctuante, 12 h a 5,8 y 12 h a 6,4, simulando una acidosis crónica, frecuente en este tipo de dietas. In vivo, estas dietas fueron asignadas a 4 terneras de 132 kg en un diseño de cuadrado latino 4 x 4, sin observar ningún efecto de la sincronización sobre la fermentación ruminal ni sobre la digestibilidad de todo el tracto. El tipo de carbohidrato afectó a la ingestión, siendo mayor en los tratamientos que contenían maíz. Los animales que recibían la dieta sincronizada para una fermentación rápida (cebada-girasol) redujeron su ingestión y rumiaron durante más tiempo el forraje sin que sufrieran problemas de acidosis ruminal.
Beef production in Spain is very specific. The production system is completely detached from the land and calves are fed high concentrate diets based on cereals from weaning to slaughtering at a young age, producing a tender and pink meat. The use of legume seeds in these high concentrate diets is increasing, although these protein supplements are poorly characterized in these feeding conditions and protein degradation can be reduced in such diets. Moreover, barley and corn are the main cereal grains used in high concentrate beef cattle diets. These cereals differ in their starch content and in their fermentation rate and extent of rumen degradation, but few efforts have been made to synchronize their degradation with protein supplements of similar degradation characteristics and maximize the efficiency of ruminal fermentation.
Due to the lack of information about ruminal fermentation in young beef cattle fed high concentrate diets, the following objectives were proposed:
a) To characterize ruminal fermentation and estimate ruminal nitrogen degradability of plant protein supplements during the fattening period.
b) To study the effects of synchrony of ruminal degradability of corn and barley starch with protein sources of different rates and extents of degradation, on ruminal fermentation, animal performance and feeding behavior.
In the first experiment, six Holstein heifers growing from 80 to 250 kg were used in a repeated measures trial to study the changes in ruminal fermentation and protein degradation of four plant protein supplements (two legume seeds and two by products from the oil industry). Heifers were fed two isoenergetic and isonitrogenous high concentrate diets with different fiber content. One diet contained 12% barley straw and the other 30% dehydrated alfalfa as forage source. Cellulolytic activity, estimated as NDF degradation of alfalfa hay incubated in situ, was very low in both diets, but it was slightly higher in the diet with 30% dehydrated alfalfa. In situ nitrogen degradability of legume seeds (peas and lupin seeds) was also higher in the diet with a higher proportion of forage. With age, gross nonstructural carbohydrate intake increased and ruminal fermentation became more amilolytic and proteolitic, increasing total VFA concentration, propionate proportion and nitrogen effective degradability of protein supplements, except for soybean meal. These two diets were assigned in the second experiment to four 300-kg growing heifers in a cross-over design to study the effect of dietary fiber level on ruminal fermentation and in situ nitrogen degradability of seven protein supplements (5 legume seeds) at the end of the fattening period. The ruminal fermentation pattern was basically amilolytic in both diets, and was not affected by dietary fiber content. Neutral detergent fiber degradation of alfalfa hay was also very low (25.5%) and values of effective degradation on legume seeds were lower than values reported by reference feeding systems, the values obtained in the present experiment being more adequate for beef cattle fed high concentrate diets. Effective degradation of soybean meal and sunflower meal were similar to values reported by feeding systems and not affected by NDF content of diets.
To study the effects of synchrony of rumen degradability between energy and protein sources, barley and corn and two protein sources, soybean meal, SBM, and sunflower meal, SFM, differing in their rate and extent of rumen degradation were combined. This resulted in a synchronized rapid fermentation diet (barley-SFM), a synchronized slow fermentation diet (corn-SBM) and two unsynchronized diets with a rapidly and slowly fermenting component (barley-SBM and corn-SFM). All diets were isoenergetic and isonitrogenous with a forage to concentrate ratio close to 10:90. In vitro, with a dual flow continuous culture system, ruminal fermentation was enhanced in synchronized diets (Barley-SFM and corn-SBM). No effect of ruminal pH, which was held constant at 6.2 or fluctuant 12 h at 5.8 and 12 h at 6.4, simulating subclinical acidosis frequently associated with these diets, was observed. In vivo, these diets were fed to four 132-kg heifers assigned to a 4 x 4 Latin square design, but synchronization had no effect on ruminal fermentation or on apparent total tract digestibility. The type of carbohydrate affected intake, being higher for corn than barley based diets. Heifers fed the rapid synchronized diet (barley-SFM) reduced intake and increased time spent chewing per unit of forage intake, avoiding problems of ruminal acidosis.

Full textKompakta arkitekturer, ternära vikter och binära aktiveringar är två metoder som är lämpliga för att göra neurala nätverk effektivare. Vi introducerar a) en dithering binär aktivering som förbättrar noggrannheten av ternärviktsnätverk med binära aktiveringar genom randomisering av kvantiseringsfel, och b) en metod för genomförande ternärviktsnätverk med binära aktiveringar med användning av binära operationer. Trots dessa nya metoder, att träna en kompakt SqueezeNet-arkitektur med ternära vikter och fullprecisionaktiveringar på ImageNet försämrar klassificeringsnoggrannheten betydligt mer än om man tränar en mindre kompakt arkitektur på samma sätt. Därför kan ternära vikter i deras nuvarande form inte kallas bästa sättet att minska nätverksstorleken. Emellertid, effekten av weight decay på träning av ternärviktsnätverk bör undersökas mer för att få större säkerhet i detta resultat.
