Uso de diferentes formas físicas e quantidades de ração pré-inicial para frangos de corte

The objective of this work was to evaluate the effect of the physical form and quantity of pre-starter diet on the broiler chicks performance. In the first trial, 684 day old males were distributed in a randomized design of three treatments with six replicates of 38 birds. The physical forms of pre-starter diets tested were: mash diet; crumb diet and pellet diet. Another was conducted with 912 day old male distributed in a randomized design of three treatments with eight replicates of 38 birds. The treatments consisted in feeding the broiler chickens with 150 g/bird; 200 g/bird and 250 g/bird. After that, all the birds were fed with the same feed program. In the first week and at 21 days old the birds fed with mash pre-starter diet had body weight gain lower than those fed crumbed and pelleted diets. The variables studied were not affected by the quantity of diets. In conclusion, the physical form of pre-starter diet was important for initial performance and the quantity of pre-starter tip to 150 g/bird did not improve the development of broiler chicks.

Suplementação da dieta de codornas com minerais nas formas orgânicas sobre o desempenho e a qualidade dos ovos

Foram realizados três experimentos com o objetivo de avaliar o efeito da suplementação de minerais na forma orgânica na dieta de codornas japonesas na fase de postura sobre o desempenho e a qualidade de ovos das aves. Os níveis de minerais utilizados por kg de ração, para cada experimento, foram: controle, 0,35, 0,70 e 1,05mg de Se orgânico (experimento 1); controle, 50, 100 e 150mg de Zn orgânico (experimento 2) e controle, 60, 120 e 180mg de Mn orgânico (experimento 3). As aves foram distribuídas em delineamento inteiramente ao acaso, sendo oito aves por parcela e seis repetições por tratamento. Foram avaliadas as características de desempenho - consumo diário de ração, peso dos ovos, porcentagem de postura, conversão alimentar por massa de ovos e por dúzia de ovos e viabilidade - e qualidade dos ovos - unidade Haugh, índice gema, porcentagens de casca, albúmen e gema, espessura de casca e gravidade específica. O Zn orgânico suplementado à dieta melhorou o desempenho das aves e a qualidade dos ovos, o Mn orgânico melhorou a qualidade da casca e reduziu o peso dos ovos e o Se não apresentou efeitos sobre as características avaliadas.

Alianças estratégicas enquanto formas microorganizacionais em cooperação competitiva: o caso da Rede Universitária de Incubadoras Tecnológicas de Cooperativas Populares - Rede de ITCPs

A threat that can be minimized by the organization in net and the use of other forms interorganizational and strategic alliances. Therefore the demonstrates the context of the competitive cooperation in network, seeking criteria of analysis of that phenomenon organizational, on the basis of a study of case of the net ITCPs and in the literature researched, aimed with that criterion and indicator for creation of a model of evaluation in the future (Factor Net) that be prominent for the drawing of those forms organizational you maintained, supportive, competitive and cooperative

Desempenho, eficiência de utilização dos nutrientes e estrutura do trato digestório de pintos de corte alimentados na fase pré-inicial com rações de diferentes formas físicas

Este estudo foi realizado com o objetivo de avaliar o efeito da forma física da ração sobre o desempenho, a utilização dos nutrientes das rações e o desenvolvimento do trato disgestório de pintos de corte na primeira semana de vida. Foram utilizados 150 pintos machos Cobb distribuídos ao acaso em três tratamentos com cinco repetições de dez aves. Os tratamentos consistiram das formas físicas farelada, triturada e peletizada de uma ração pré-inicial comercial. Com exceção da moela, os órgãos do trato digestório e a estrutura morfométrica do intestino não foram influenciados pela forma física da ração. Maior digestibilidade do N foi obtida com a ração peletizada, enquanto a ração triturada possibilitou maior digestibilidade do EE. A energia metabolizável determinada para a ração farelada foi menor que a obtida nas demais formas físicas da ração. As aves alimentadas com ração farelada tiveram menor consumo de ração e ganho de peso e pior conversão alimentar. Ingeriram ainda menos energia, apresentaram menores retenções de proteína, gordura e energia corporal e utilizaram maior proporção da energia ingerida para produção de calor. As rações pré-iniciais na forma peletizada ou triturada possibilitam maior aproveitamento dos nutrientes da ração pelos pintos e melhor desempenho.

Formas de propagação de espécies de uso medicinal popular em cinco municípios do estado do Amazonas

This work was carried out in five counties of Amazon State, Brazil, along the Solimoes/Amazonas and Negro Rivers. The objective was to identify the several forms of natural and induced propagation with medicinal plants, natives and exotics. The peoples were interviewed, with visit and recollection of botanical materials to herborization and reproduction. The greatest parts of plants propagate by seeds (65,8 per cent) and cutting (23,5 per cent). It was showed several species that reproduce by other strategies, like bulbs, rhizomes or brotations. The Amazonian species, in general, propagate by seeds, with some exceptions.

Fabricação de malha de trama utilizada como pré-formas na indústria de compósitos e avaliação das propriedades mecânicas

In the manufacture of composite, textile materials are being used as reinforcement. Generally, the combination of the matrix with the textile material in the form of fibres or yarns is used depending on their distribution in the web. In the present work, in place of fibres or yarns, a knitted structure in the form of the final product which is defined as preform. The preform is weft knit manufactured with polyester filaments. In the manufacture of composite, polyester resin was used as matrix. The physical and mechanical properties as well as the formability of the weft knit were analysed. The physical and mechanical properties as well as the formability of the knitted structure were analysed. The results obtained on the analysis show that the courses and wales of the weft knit structure and the tensile properties help the formability of the structure and the impregnation of the resin. It could be clearly observed that composite structure in the direction of the courses support more tension than in the direction of the wales. In relation to the three points flexural tests it was possible to note that there was more flexion in the direction of wales, what was expected. It was also possible to note that there are other advantages such as reduction in the loss of materials used, homogeneity in the distribution of the knitted structure in the mould, reduction in the preparation time and also in the reduction in the cost of manufacture

Longevidade de sementes de camu-camu submetidas a diferentes ambientes e formas de conservação

O camu-camu (Myrciaria dubia (H.B.K.) McVaugh) produz fruto com grande potencial para extração de ácido ascórbico, que apresenta relevante importância econômica e social, com inúmeras aplicações industriais. O objetivo deste trabalho foi avaliar o efeito de diferentes formas de conservação e ambientes de armazenamento, sobre a manutenção da viabilidade das sementes. O delineamento experimental inteiramente casualizado, utilizando parcelas subsubdivididas, onde os fatores foram: ambiente de armazenamento (ao ar livre, em água, em câmara a 5 e a 10 ºC), forma de conservação (sementes com polpa - CP, sementes sem polpa - SP e sementes lavadas e tratadas - LT) e período de armazenamento (0; 2; 4 e 6 meses). O critério de avaliação adotado foi a protrusão da raiz primária. As sementes armazenadas em água, nas formas SP e LT, apresentaram germinação maior que 90%. As sementes nas formas CP e LT, armazenadas a 5 e a 10 ºC, tiveram germinação acima de 89%. O armazenamento em água e ao ar livre não afetou a germinação, podendo as sementes serem armazenadas durante o período de seis e quatro meses, respectivamente. As sementes CP, armazenadas em água, tiveram menor tempo médio para germinação. O índice de velocidade de germinação aumentou com o período de armazenamento e foi maior nas sementes armazenadas na água em todos os períodos. As sementes com polpa apresentaram menor índice de velocidade de germinação em todo o período de armazenamento avaliado.

Formas e função do discurso do outro no gênero monográfico

The present work investigates related discourse in rewriting discursive practices, at monographic works specifically at the theoretical foundation section. Focalizing some discursive strategies of voice management (direct and indirect discourse and modalization voice) we detach the introduction way and function of cited discourse. To do so, it were analyzed eighteen monographic works: nine of them final graduation works and other nine specialization works seeing that each works belonging to the same student, in two different stages, in the period from 2003 in graduation conclusion to 2005 in the end of specialization course. The data reveal that the monographic writer/student emphasizes the use of direct discourse in graduation works while in specialization works there was an emphasis at indirect speech. The analysis the way they introduce cited discourse pointed out that writer/student in graduation course such as specialization student make meaningless constructions when they do not use discendi verbs, they demonstrate difficulties inarticulate citing discourse with cited discourse. In what is related to functions of cited discourse we verify that the student/writer, in both stages or levels give emphasis to the function maintain an assertion, indicating that other s discourse serve mainly as a resource of authority just because that this function reveals the absence of a dialog between student writing and cited discourse. In a general way, the forms of other s discourse claim a form of writing that is found starting from a sequence of cited discourse in what student/writer voice in graduation and specialization comes to text surface just few times, but most of the times, the student takes other s words as they were themselves, every time there is an overlap of author/source

O ensaio jornalístico na revista Veja: uma análise multidimensional

This work has as objective generality to make a multidimensional analysis in the genre journalistic assay, communicative genre that, beyond complex and multimodal, presents hybrid characteristics. Specifically, with the intention to propose defining criteria of the cited genre, this research looks for to establish differences and similarities between the assay and other genres of the same sphere, from the description and interpretation of used multimodal resources. The analysis of the formal, schematical and rhetorical resources identified in the formatting of the journalistic assay sample that the analyses are supported in the socio-semiotic and socio-rhetorical approaches. In the formal dimension, we contemplate elements that constitute design of the text, including the forms of representation from the typography, the colors, images, as well as the aspects communicative-linguistics: the modalization indices, the communicative operators and the category time; in the schematical dimension, we present the organizational structure, considering the rhetorical movements postulates for Swales (1990) and in the rhetorical dimension we observe the categories: who writes, for who it writes, on what it writes and where writes. The adopted methodologicals postulates are of qualitative nature and the procedure is documentary, data that in we are valid them written texts of this genre as analysis object. Corpus it is constituted by a composed sample for 14 extracted texts of a set of 173 propagated journalistic assays weekly for the magazine Veja, in the period between August of 2004 and January of 2008. The analysis of the data showed that the journalistic assay, object of this study, materializes through multiple symbolic representations and multiple subjects that turn since a small episode of the daily facts of great social relevance in the present time, of historical and cultural nature, nationwide or international. Used for the first time by Montaigne in 1580, to assign, in saying of the proper author, written fast on its life and historical events, which could nor be remembered later , the term `assay' was enriched with other specifications, of form to enclose the one that if they call scientific assay today, academic assay, journalistic assay and other types of specific assays. These denominations have to see with the enrollment of the members of diverse of practices communities, in virtue of the multiplicity of activities carried through in these spheres. The conclusions the one that we arrive had been the following ones: 1. the discursive genre is not a pure entity, in virtue of the multiplicity of situations where the sorts if insert in the social actions; 2. the institutions define the configuration of one definitive genre, also its proper assignment, since for backwards of all discursive genre a voice exists to discipline - institutional voice, and in the case of the assays for analyzed us, the institutional voice if it presents, really, as a defining trace; 3. the journalistic assay, for its multiple symbolic representations, multiple subjects and for passing explicit or implicit opinions of its author, resembles it other genres, being able, therefore, to be inserted in a colony of opinionatives genres

Modos de ler, formas de escrever a literatura enquanto objeto da ficção de Enrique Vila-Matas

Este trabajo busca analizar cómo algunos aspectos presentes en la obra de ficción del escritor catalán Enrique Vila-Matas permiten pensar las prácticas de la escritura literaria contemporánea. A partir de una forma híbrida que reconsidera las relaciones tanto entre los géneros como entre los discursos crítico y de ficción, la obra del autor se propone reflexionar sobre sus propias posibilidades en el contexto sociocultural contemporáneo. De este modo, a través de una ficción que muchas veces adquiere los atributos del ensayo, Vila-Matas trae al centro de sus enredos la discusión de cuestiones relacionadas con los impases de una escritura que vuelve su atención para el destino de una tradición literaria desvinculada de los preceptos meramente mercadológicos contemporáneos. Su manera crítica de abordar la literatura y la experimentación en busca de nuevas posibilidades permite asociarlo tanto a Laurence Sterne como al proyecto literario de Jorge Luis Borges. Estos autores tienen propuestas que tratan de superar los límites del texto, ya que ahí está el deseo de acogerse a la ficción para demostrar la inestabilidad de los elementos de una cultura, apropiándose y desestabilizando los discursos y las claras distinciones entre los saberes. En este sentido, las diversas formas en que Vila- Matas se apropia de los textos de otros y construye una obra de carácter fuertemente intertextual denuncian jerarquizaciones y modos de circulación de textos que permiten aproximarse de la tensión existente entre temas como influencia, citación, prácticas de lectura y escritura

Obtenção e caracterização do sistema compósito alginato de sódio-dióxido de titânio em formas de pó e de membrana

The alginates are copolymers of 1→4-linked β-D-mannuronic acid (M) and α-Lguluronic acid (G) residues that are arranjed in a block structure along a linear chain. Titanium dioxide, TiO2, is a ceramic material and can exist in three distinct crystallography forms: anatase, brookite and rutile. composites of organic and inorganic materials have better properties than the components alone. Thus, this study aims to synthesize, characterize and analyze the composite NaAlg-TiO2 in the form of powder and film. The synthesis of composite powders was performed using the sol-gel process and obtain the composite film was performed using the slow evaporation process, then the composites were analyzed by infrared spectroscopy, fluorescence x ray, thermal analysis, attenuated total reflection (ATR), x ray diffraction and impedance spectroscopy. The X ray diffraction patterns of composite powders show that with increasing calcination temperature, there were no complete transition of rutile-anatase crystalline phase, since at all temperatures studied (300, 500, 700, 900 and 1100ºC) were observed peaks of anatase phase. Thermal analysis shows that at 400°C caused the decomposition of sodium alginate in sodium carbonate and above 600°C, we observe an exothermic peak related to the decomposition of sodium carbonate and in the presence of titanium dioxide becomes sodium titanate. The XRD results confirm the formation of sodium carbonate at 700ºC and the formation sodium titanate in the temperature range 900-1100ºC. The sodium titanate influenced the electrical properties of the material, because with increasing temperature there was a decrease in conductivity, probably due to the creation of Ti vacancies, since the sodium can induce the reduction of surface Ti4+ ions into Ti3+ species. The infrared spectra of the composites in the form of powder and film showed a small shift in the bands compared to the spectrum of pure alginate, indicating that these shifts, even small ones, have evidence of miscibility between the polymer and ceramic material

Trabalho, corpo e subjetividade: toyotismo e formas de precariedade no capitalismo global

Nos últimos trinta anos de desenvolvimento capitalista, ocorreram transformações significativas nas diversas instâncias do ser social, com destaque para o mundo do trabalho e da reprodução social. Desenvolve-se o toyotismo, ideologia orgânica da nova produção capitalista, 'momento predominante' da reestruturação produtiva do capital. Sob o toyotismo, tende a constituir-se, pelo menos como 'promessa frustrada' do capital, o que iremos denominar 'compressão psicocorporal'. Esta constitui-se como um elemento da nova disposição sócio-subjetiva instaurada pelo toyotismo que caracteriza uma nova experiência do corpo, tanto no processo de trabalho quanto no processo sócio-reprodutivo.
