Relative development of tissues, commercial meat cuts and live weight components in Saanen goats

Objetivando avaliar o desenvolvimento relativo dos componentes do peso vivo (PV), dos cortes comerciais e dos tecidos da carcaça, utilizaram-se 40 cabritos Saanen. Os animais foram abatidos ao atingir 5,0; 12,5; 20,0; 27,5 e 35,0 kg de PV e a carcaça foi seccionada em paleta, pescoço, 1ª a 5ª costelas, 6ª a 13ª costelas, peito/fralda, lombo e perna. A perna foi dissecada em ossos, músculos e gordura. Utilizou-se a equação alométrica Y=aXb para estimar o desenvolvimento relativo. O crescimento do tecido ósseo foi precoce, o do tecido muscular intermediário e o da gordura crescimento tardio, uma vez que a gordura subcutânea é depositada mais tardiamente. Os cortes comerciais apresentaram coeficiente de alometria isogônico, com exceção do corte da 6ª a 13ª costelas e do peito/fralda. O desenvolvimento da carcaça e dos não-componentes da carcaça acompanhou o peso de corpo vazio. Cabritos com 35 kg de PV possuem proporção de músculos e relação músculo:osso adequadas, mas apresentam proporção de gordura maior que a observada nos animais abatidos com 20 kg de PV.

Efeito de diferentes níveis de energia e de programas de alimentação sobre o desempenho de frangos de corte abatidos tardiamente

O experimento foi realizado com o objetivo de avaliar diferentes níveis de energia metabolizável e de programas de alimentação sobre o desempenho de frangos de corte no período de 42 a 57 dias de idade. Foram utilizados 1.600 pintos machos da linhagem Cobb, em um delineamento inteiramente ao acaso, em esquema fatorial 2 x 4, composto de dois níveis de energia (3.200 e 3.600 kcal EM/kg) e quatro programas de alimentação (recomendações de aminoácidos). As aves foram alimentadas com ração à base de milho e farelo de soja até os 41 dias de idade, quando foram pesadas, homogeneizadas e separadas por tratamento, dando-se início ao fornecimento das rações experimentais. Foram avaliados dados de ganho de peso, consumo de ração e conversão alimentar ao final de cada período experimental, a conversão calórica e o índice de eficiência produtiva para todo o período experimental. O nível de 3.600 kcal EM/kg melhorou o desempenho das aves, mas o fracionamento das exigências de aminoácidos digestíveis em dois períodos piorou os resultados. O desempenho no período de 50 a 57 dias de idade indicou que o abate tardio deve ser antecipado em uma semana, pois, após os 49 dias de idade, ocorre piora na conversão alimentar.

Características dos frutos de cultivares de pessegueiros e nectarineira, no município de Botucatu – SP

The research had as purpose to evaluate the fruits physical-chemical characteristics of peach cultivars (CP-9553 CYN, CP951 C, Tropic Beauty, Cascata 953, Cascata 797, Cascata 587, Precocinho, Conserva 693, Diamante Mejorado, Turmalina e Marli and Sun Blaze nectarine at Botucatu, São Paulo, Brazil region. It were evaluated the fruits fresh matter, longitudinal and transversal diameters, and the crop period. In relation the physical-chemical characteristics of fruits, it was evaluated the texture, the pH, tritatable acid and soluble solids. The results showed significant differences between the cultivars where the fruits fresh matter were 68,6g ('CP-9553 CYN') and 141,35g ('Cascata 953'); the fruits longitudinal diameter were 50,32mm ('Marli') and 72,12mm ('Conserva 693') and the fruits transversal diameter were 50,50mm ('CP-9553 CYN') and 62,90mm ('Cascata 953'). The post-harvest characteristics also had significant differences. The texture had changes at 517,00gf ('Marli') and 168,47gf ('Precocinho'); the soluble solids were 9,73 degrees Brix on Marli cultivar. The pH was about 3,36 on 'Diamante Mejorado' until 4,48 on CP-9553 CYN cultivar and the acidity was 0,96g of citric acid 100g(-1) fruits juice on Tropic Beauty cultivar. The crop period of the cultivars evaluated were the end of September month until 15(th) November month, being the earliest cultivars Tropic Beauty, CP-951 and CP-951 CYN and the latest cultivar were Marli. It was observed that the news cultivars, until in observations, with Cascata 953, Cascata 797 and Cascata 587, showed crops potential at Botucatu/SP region.

Mortalidade infantil em município da região Centro-Oeste Paulista, Brasil, 1990 a 1992

INTRODUÇÃO: A mortalidade infantil em Presidente Prudente, SP (Brasil), foi estudada no período de 1990 a 1992, a partir de aplicação de métodos para obtenção de diagnóstico coletivo que orientassem a identificação e escolha de estratégias de controle de problemas locais. MATERIAL E MÉTODO: Foram utilizadas declarações de óbito colhidas no cartório, cujos dados originais foram corrigidos por meio de pesquisa documental nos serviços de saúde e entrevistas domiciliares. Para estudar variáveis como idade materna e peso ao nascer foram utilizados os dados do Sistema de Informações sobre Nascidos Vivos (SINASC). A qualidade dos dados originais das declarações de óbitos foi inicialmente analisada pela quantidade de informações, sensibilidade, especificidade e valor de Kappa. RESULTADO: A sensibilidade global para a causa básica de óbito foi 78,84% e Kappa igual a 71,32 para o total de causas. Ocorreram 189 óbitos, sendo 66,15% no período neonatal (41,28% durante o primeiro dia de vida) e 33,85% no infantil tardio. O peso ao nascer de 58,28% dos óbitos foi menor que 2.500g. As causas básicas de óbito foram estudadas segundo a possibilidade de serem prevenidas (método desenvolvido por Erica Taucher) por grupos de causas reduzidas utilizadas no International Collaborative Effort (ICE), causas múltiplas e distribuição geográfica. Observou-se que nos óbitos ocorridos até 27 dias, 22,23% poderiam ser evitados por adequada atenção ao parto, 20,64% seriam redutíveis por diagnóstico e tratamento precoce, 13,75% por bom controle da gravidez e apenas 7,94% não evitáveis. Das mortes ocorridas no período infantil tardio, 12,17% foram classificadas como outras preveníveis e 4,23% foram consideradas não evitáveis. Segundo os grupos do ICE, 58,74% faleceram por imaturidade ou asfixias; 19,58% por infecções e, 12,17%, por anomalias congênitas. CONCLUSÃO: Os resultados sugerem prioridade para assistência obstétrica no trabalho de parto e atenção pediátrica por baixo peso ao nascer, entre outras. A análise por causas múltiplas mostra que 76,05% dos óbitos têm as causas básicas relacionadas a causas perinatais e confirma a relação entre as deficiências de peso e as complicações respiratórias do recém-nascido. As complicações maternas também relacionaram-se com o baixo peso. Identificaram-se grandes diferenças no coeficiente de mortalidade infantil entre as áreas da zona urbana não somente restritas aos valores, como também ao tipo de doenças responsáveis pela ocorrência do óbito. Conclui-se haver vantagem no uso associado das quatro técnicas que são complementares, tanto para estudo, como para planejamento de ações dirigidas à prevenção da mortalidade infantil.

Nexus: da relacionalidade do princípio à metafísica do inominável em Nicolau de Cusa

We indicate the idea of nexus or conexio, thought of as intelligible connection with the intelligent, the foundation on which the reason why you can understand and name, even if inadequately, what the intellect sees incomprehensible and unnameably. Thus, it opens a way for our research: we will take the idea of nexus as fundamental to the interpretation of the divine names and the "metaphysics of the unnameably" and we show how the divine names, mainly in possest, mirrored in the Trinity, relatedness of the principle and therefore also the nexus. For that you need to think some preliminary questions: we will place Nicholas of Cusa in the tradition of medieval Christian Neoplatonism, we resume some discussions on the problem of naming and the philosophy of language in his thinking, we will reflect such thinking is molded from active dialogue with the tradition and how it is your speculation is founded upon the dynamic and dialectical relationship between philosophy and theology to be thought of in our text using the relationship between faith and understandig (intellectus). After introductory clarify these issues we will come to consider introductory understanding of the Trinitarian Beginning and speculation about the nexus taking as its starting point from where the De venatione sapientiae nexus or conexio is designed as a hunting field of wisdom and the First Book of De docta ignorantia where the maximum is now thought of as one and triune. From the Second Book of the same work and the Idiota. De mente we will show in what sense the universe and men, as imago dei, imitate the eternal Trinity. Finally, we will resume the notion of the scientia aenigmatica of De beryllo and some information that will clarify that Nicholas assumes the divine names as enigmas. Finally, we will try to show that the enigmatic or symbolic names also mirror the triune Beginning principle. So, before we return some traces of this aspect in some divine names and texts of the "late period" and then conclude with that which in itself already indicates the nexus and therefore the trinity: possest

A evolução do lítio em estrelas do tipo-solar através do diagrama HR

Important advances have been made along the last decade in the study of the lithium behavior in solar-type stars. Among the most important discoveries what attracts attention is that the distribution of lithium abundance in the late F-type giant stars tends to be discontinuous, at the same time of a sudden decline in rotation and a gradual decline according to the temperature for giant red stars of such spectral type. Other studies have also shown that synchronized binary systems with evolved components seem to keep more of their original lithium than the unsynchronized systems. evertheless, the connection between rotation and lithium abundance as well as the role of tidal effects on lithium dilution seem to be more complicated matters, depending on mass, metallicity and age. This work brings an unprecedented study about the behavior of lithium abundance in solartype evolved stars based on an unique sample of 1067 subgiant, giant and supergiant stars, 236 of them presenting spectroscopic binary characteristics, with precise lithium abundance and projected rotational speed. Now the lithium-rotation connection for single and binary evolved stars is analyzed taking into account the role of mass and stellar age

Prospecção e caracterização de genes associados ao processo de indução floral em cana-de-açúcar

The northeastern region is responsible to 14.32% of sugarcane national production. This lowered contribution is due to edaphoclimatic condition. Flowering is a vital process to plant which consumes lots of energy and it culminates in a process called isoporization. This one can give in a decreasing of 60% on alcohol and water production. It may consider that cropped sugarcane has a hibrid with octaploid genome, there are varieties with a flowering standard until of non flowering. Using this natural genetic potential on different croppings of sugarcane, the aim of this work was to understand as this process occurs by the usage of subtractive approaches. The total RNA was extracted using Trizol of peaks of merisematics of croppings with induced flowering and other with late flowering. From this total RNA were built four subtractives libraries (B1- induced early flowering subtracted on late flowering not induced; B2- late flowering not induced subtracted induced early flowering; B3- induced early flowering subtracted of not induced early flowering; B02- not induced early flowering subtracted from induced early flowering) using kits Super Smart cDNA synthesis and BD Clontech kit select cDNA subtraction (Clontech). This material was clone don vector pGEM T-easy(Promega) and changed in competent cells of E.coli DH10B. Given analysis sequence was carried out a program BLASTn against database of NCBI and genome of Arabidopsis thaliana, rice and maize. Clones were grouped in 9 different classes according to function. Some factors already related as couples of flower induction were identified at different libraries. And grouped proteins with cell cycle and it controls were presents, mainly kinases proteins. Related factors to proteic sinthesis, metabolism, defence, cell communication were also given in both libraries .Some identified genes did not show similarity on database or homology with hypothesis function, and it can represents new genes to be deposited in international database. These results offers that some identified on sugarcane, classified as on factors classes, cell cycle and cell communication, trough unknown genes, can be linked with genetic changing to the flowering process found in the northeastern region

Habitação e modernização: Cidade Nova e maneiras de viver em Natal no início do século XX

Analyses the presence of new standards of habitation detected in the construction of the region called Cidade Nova, in the first s years of the XX century. Associates the presence of these new patterns with the historical moment lived by the capital, marked by the urban modernization and by the changes of local life. Map voices that, introduced by the republican groups since 1889, pronounced the overcome of the old city of the XIX century asseverated a new model of town. Make use, as fundamental fonts of research, of the urban chronicles produced by the local intellectuals and the newspapers, like A República. Dialog with chronics that includes since propositions about the colonial past until the preoccupations about the acting of the State on how to order the public space. Identifies on those texts the political motivations and the elements whose where inherent to capitalism that accelerated the changes occurred in the urban space. Demonstrates the gradual occupation of Cidade Nova as an important modification happened in the city from that time on. That neighborhood adopted a new model on how to construct the houses of their citizens and helped to promote the urban life as a whole. From now on, Natal has a space meant for the home of their richest families. Recognizes, from many ways, many discourses, manners of living that was legitimized by the changing of the XIX to the XX century and has his highest point in the 1920´s. And it was representative of the strong attachment about the habits of refinery and order in the essence of the private life of the local urban elites

As estruturas sociais e econômicas do Império Romano do Ocidente e o estabelecimento do reino dos visigodos nas Galliae Aquitania e Narbonensis

In the year 376 of the Common Era, a tribe of Germanic warriors known as Tervingi , of Gothic extraction, crossed the Hister (Danube) river due south, entering the Roman Empire. They fled the Huns, a nomadic group that came plundering their way from the East. It did not take long for a conflict between the Roman imperial authorities and the refugees to begin. Peace was reached in 382 and, henceforth, the Tervingi would be officially foederati (allies) of the Romans, gaining the right to remain an autonomous tribe inside the borders of the Empire. For the next thirteen years the Tervingi warriors fought beside the Roman imperial armies in every major conflict. Nevertheless, after the death of the emperor Theodosius I in 395, their relations deteriorated severely. In theory, the Tervingi remained Roman allies; in practice, they begun to extort monies and other assets from the emperors Honorius and Arcadius. The sack of Rome by the Tervingi king Alaric in 410 was both the culmination and the point of inflection of this state of affairs. During the 410s the Tervingi warriors would fought again beside the Roman Imperial armies and be rewarded with a piece of land in the southwestern portion of the Gallic diocese. Dubbed Visigoths , they would remain trusted Roman allies throughout the next decades, consolidating their own kingdom in the process. This dissertation deals not only with the institution of the Visigothic kingdom in the southwestern portion of the Galliae but also with the social and economic conditions that hindered the Roman ability to defend their territory by themselves, hence opening opportunities for foederati like the Tervingi to carve out a piece of it for themselves.

Ocidentalização, territórios e populações indígenas no sertão da Capitania do Rio Grande

The objective of this work is to understand some of the modifications caused for the phenomenon of the westernization in the hinterland of the Capitania do Rio Grande e in the life of the indians populations that inhabited there during the Colonial Period. We break of the quarrel of Serge Gruzinski concerning the westernization, understood while immersed phenomenon in the context of the expansion of the commercial capitalism and that, for the imposition of the culture occidental person to the alteridades of the New World, emprende the conquest of its territories, bodies and souls. The space clipping has covered the hinterland of the Capitania do Rio Grande, specifically the colonial territory of the Freguesia da Gloriosa Senhora Santa Ana do Seridó. The chosen chronological limit for the research corresponds to the Colonial Period and part of the Imperial one. However, the emphasis falls again on the period that it initiates in 1670, year of the oldest concession of would sesmaria known until the moment in the hinterland of the Rio Grande, extending itself until the decade of 1840. Sources of written by hand nature, cartographic printed and compose the used document roll: official correspondence and legislation, petitions of would sesmaria, inventories post-mortem, justifications of debt, registers of parish, maps, action civil court jurisdiction, notes of notary's office, land landmarks. We take the method, analyzed for Carlo Ginzburg, to cross these sources between itself and to detect its implied particularitities and ideas in the space between lineses, but, attributing it status to they of a colonial speech, fruit of the bureaucracy of where it was originated and of the social place of who produced it. We look for to demonstrate, throughout the work, that the phenomenon of the westernization desestruturou the aboriginal societies and its habitat, constructing, over its rubbles, a colonial territory that found in the cartography of the Freguesia de Santa Ana an efficient instrument of control of the space and the population. On the other hand, if the imposition of the culture occidental person exterminou great part of the native population that inhabited the hinterland of the Rio Grande, the remainders of these indians and the mestizos of descending them had survived in diverse ways in the freguesia: in the condition of captives of war or in regimen of servile work, as living or assistants in the farms, populations and village; rambling without route in the fields and the population spots; as mediating agents between the world occidental person and the native, exerting military or civil positions and still appealing to Justice in search of its rights of inheritance. Experiences of slavery, servitude, errância and mediation, but, also of resistance, adaptation, mestization in the Freguesia de Santa Ana

Relação entre o ciclo sono e vigília e a função cardiorrespiratória em estudantes de medicina

Students, normally, present an irregular sleep pattern characterized by delays in sleep onset and offset from weekdays to weekends, short sleep duration on weekdays and long sleep duration on weekends. The reduction of the necessary sleep and the irregularity in the sleep patterns provoke relevant short- and long-term impairments on performances, for example, in cardiorespiratory function. The cardiorespiratory performance represents, in addition to fitness, traces associated to health conditions and in several studies to pattern and/or individual s sleep quality. The aim of this study was to evaluate the pattern of the sleep-wake cycle and the cardiorespiratory function of medical students under different class schedules. The study was accomplished with two classes of medical students of UFRN, one had classes at 7 am (n = 47) and the second had classes at 8 am (n = 41) during the week. On the first stage of the study all volunteers filled out an anamnesis, the International Physical Activity questionnaire, the Pittsburgh index of sleep quality, the Portuguese version of the Horne and Östberg cronotype questionnaire, the Health and Sleep questionnaire and the Epworth Scale of Somnolence (ESS). On the second stage, 24 students (12 of each class) had their activity rhythm monitored by actimeters set to record activity at a 2-min interval for 14 days concomitant to the completion of the sleep diary. In this same stage, each volunteer performed the effort test (treadmill) only once in the morning period (between 9:00 and 11:00). The students showed an irregular pattern of the sleep-wake cycle and this irregularity is strongly influenced by the class schedules, in addition to the contribution of the academic demand, social activities and endogenous factors. The students who woke up earlier showed greater irregularity in the sleep-wake pattern. The earlier was the class schedule the worse was the sleep quality and the greater was the frequency of students with excessive diurnal somnolence. The classes schedules and the irregular pattern of the sleep-wake cycle did not show effect on the cardiorespiratory performance of the medical students. The performance on the test seems to be affected by other factors, which can be related to the pattern of the sleep-wake cycle or not. Therefore, it is suggested that the late start of classes provokes less irregularity on the pattern of the sleep-wake cycle. However, it was observed that this irregularity and the class schedule seem not to affect the cardiorespiratory performance directly
