Programa de P?s-Gradua??o em Hist?ria. Departamento de Hist?ria, Instituto de Ci?ncias Humanas e Sociais, Universidade Federal de Ouro Preto.Esta tese de doutoramento se prop?e a analisar a Provedoria das Fazendas dos Defuntos e Ausentes, Capelas e Res?duos no Brasil colonial. Isso envolve diretamente o papel desempenhado por tal institui??o tanto no cumprimento quanto na administra??o das disposi??es testament?rias, fossem aquelas referentes aos legados pios ou as concernentes ? transmiss?o dos esp?lios para os herdeiros. Pretende-se avaliar os significados sociais, econ?micos e espirituais da Provedoria, bem como o que ela representou em termos de pol?tica e administra??o do governo portugu?s em terras bras?licas. Essa empreitada envolve tamb?m a compreens?o de outros aspectos relacionados ? din?mica do dito ju?zo, tais como as pr?ticas institucionais dos seus membros no exerc?cio cotidiano de suas atribui??es, as rela??es dos diversos oficiais com os grupos de poderes locais e com outras autoridades rein?is, os desvios de conduta e os conflitos entre a norma e a pr?tica.This doctorate thesis proposes to analyze the Provider of the wealths of the Dead and Absentees, Chapels and Residues in the colonial Brazil. This directly involves the role played by such institution both in fulfillment and administration of the testamentary dispositions, being them concerned to the pious legacies or to the spoils to be passed to the heirs. The intent here is to evaluate the social, economic and spiritual meanings of the Provider, as well as what it represented in terms of politics and administration of the Portuguese rule in the Brazilian lands. This task also involves the comprehension of other aspects related to the dynamics of such judgement, such as the institutional practices of its members in their daily doings, the relations of the several officers with the groups of local and other authorities, the misconducts and also the conflicts between norm and practice

Selection of common bean families for resistance to anthracnose, grain yield and carioca grain type

Na obten??o de cultivares de feij?o com resist?ncia ? antracnose, outros atributos agron?micos tamb?m devem ser considerados para atender a prefer?ncia do consumidor e do produtor. Neste trabalho, objetivou-se identificar fam?lias de feij?o que re?nam, al?m da resist?ncia ? antracnose, alta produtividade, gr?os tipo Carioca e porte ereto. Foram cruzados os genitores CNFC 10706, B1 portador do alelo de resist?ncia ? antracnose Co-4 e H147 portador do alelo de resist?ncia Co-5. Os tr?s possuem gr?os semelhantes ao Carioca. Inicialmente foram avaliadas 224 fam?lias F2:3, derivadas dos tr?s cruzamentos, mais a cultivar Talism? como testemunha, no inverno/primavera de 2004, em Lavras, com base no tipo de gr?o. Foram selecionadas 99 fam?lias F2:4 e avaliadas com a testemunha Talism?, na seca de 2005 em Lavras e Lambari. Essas 99 fam?lias foram tamb?m inoculadas com as ra?as 593 e 337 de C. lindemuthianum, para auxiliar na sele??o daquelas portadoras dos alelos de resist?ncia Co-4 e Co-5. As 35 fam?lias F2:5 remanescentes, foram avaliadas no inverno/primavera de 2005, em Ijaci, MG. Em todos os experimentos foi utilizado, o delineamento l?tice quadrado. As 35 fam?lias foram novamente inoculadas com as ra?as 65 e 321. Por meio das inocula??es e tamb?m com o uso de um marcador molecular SCAR ligado ao alelo Co-4, foi poss?vel identificar a constitui??o gen?tica da maioria das 35 fam?lias quanto ? rea??o antracnose e selecionar quatro que re?nem, simultaneamente, tipo de gr?os semelhante ao Carioca, porte ereto e boa produtividade, al?m de serem portadoras dos alelos Co-4 e Co-5 de resist?ncia ? antracnose.Funda??o de Amparo ?

So the aims of this research were to select common bean families resistant to anthracnose, high grain yield, Carioca grain type and upright plant type. The lines CNFC 10706, B1 and H147 were crossed. All of them have Carioca grain type. The B1 line is resistant to anthracnose due to the Co-4 allele, and the H147 due to the Co-5 allele. From the CNFC 10706 x H147, CNFC 10706 x B1 and H147x B1, 224 F2:3 families plus the check Talism? were evaluated in the winter/spring of 2004, in Lavras county, based on grain type. Ninety nine families were selected and evaluated, plus the check, in the seca of 2005 at Lavras and Lambari county. The families were also inoculated with the 337 and 593 races of C. lindemunthianum for selecting those with the Co-4 and Co-5 resistant alleles. The 35 selected families (F2:5) were evaluated in the winter/spring of 2005, in Ijaci county. The square lattice design was used in all experiments. Those 35 families were also inoculated with the 65 and 321 races of C. lindemunthianum. Through the inoculations and the Co-4 SCAR marker the genetic constitutions of most of the 35 families were identified. Four families were selected with Carioca grain type, upright plant type, high grain yield and besides bearing the Co-4 and Co-5 alleles for anthracnose resistance

Tearing Out the Income Tax by the (Grass)Roots

Landscapes are increasingly fragmented, and conservation programs have started to look at network approaches for maintaining populations at a larger scale. We present an agent-based model of predator–prey dynamics where the agents (i.e. the individuals of either the predator or prey population) are able to move between different patches in a landscaped network. We then analyze population level and coexistence probability given node-centrality measures that characterize specific patches. We show that both predator and prey species benefit from living in globally well-connected patches (i.e. with high closeness centrality). However, the maximum number of prey species is reached, on average, at lower closeness centrality levels than for predator species. Hence, prey species benefit from constraints imposed on species movement in fragmented landscapes since they can reproduce with a lesser risk of predation, and their need for using anti-predatory strategies decreases.authorCount :

Presenteeism in hospital nurses

This quantitative, descriptive, cross-sectional research aimed to determine the estimated productivity of health-related limitations at work in 129 nurses working in direct care delivery to critical and potentially critical patients. Instruments were applied for socio-demographic and functional characterization and for the evaluation of presenteeism (Work Limitations Questionnaire). Statistical Package for the Social Sciences software was used for data analysis. In this study, 75% of nurses obtained a lost productivity index of up to 4.84%. The physical demand domain represented the major limitation for these professionals (25%). Presenteeism was directly correlated to health care, occurrence and number of absences, and indirectly related to work time at the unit. It was concluded that organizational or individual factors influence individuals' productivity, in view of the circumstances involving care delivery to critical and potentially critical patients.Estudio cuantitativo, descriptivo y transversal con el objetivo de determinar la productividad supuesta de las limitaciones en el trabajo relacionadas con la salud de 129 enfermeros que asisten a pacientes críticos y potencialmente críticos.

Bird-spiders (Arachnida, Mygalomorphae) as perceived by the inhabitants of the village of Pedra Branca, Bahia State, Brazil

This paper deals with the conceptions, knowledge and attitudes of the inhabitants of the county of Pedra Branca, Bahia State, on mygalomorph spiders locally known as 'caranguejeiras' (bird-spiders). It is launched here a new filed within ethnozoology: ethnoarachnology, which is defined as the transdisciplinary study of the relationships between human beings and bird-spiders. Data were collected from February to June 2005 by means of open-ended interviews carried out with 30 individuals, which ages ranged from 13 to 86 years old. It was recorded some traditional knowledge regarding the following items: taxonomy, biology, habitat, ecology, seasonality, and behavior. Results show that bird-spiders are classified as "insects". The most commented aspect of the interaction between bird-spiders and inhabitants of Pedra Branca is related to their dangerousness, since they said these spiders are very venomous and can cause health problems. In general, the traditional zoological knowledge of Pedra Branca's inhabitants concerning these spiders is coherent with the academic knowledge

Efeito de diferentes tratamentos t?rmicos sobre microestrutura e microdureza de um sistema a?o C-Mn/revestimento de inconel 625.

A utiliza??o de tubos de a?o C-Mn na ind?stria de ?leo e g?s ? muito comum desde o nascimento desta ind?stria. Mesmo com a grande evolu??o da metalurgia destes a?os ao longo das ?ltimas d?cadas, o desafio de desempenho em ambientes severos de corros?o devido ?s caracter?sticas reativas (H2S, CO2) do petr?leo e seus derivados, imp?em uma nova era para a fabrica??o de tubos. A solu??o tecnol?gica mais direta seria a utiliza??o de a?os com alta liga (Ni, Cr) e/ou superligas de n?quel. No entanto, os custos de produ??o tornariam invi?veis pelo alto custo destes materiais. Neste contexto, ? crescente iniciativas de pesquisas para o desenvolvimento de overlay e/ou cladding, ou seja, revestimentos de a?os C-Mn usando superligas de n?quel e a?os inoxid?veis. Neste trabalho, foi utilizada a deposi??o de uma camada da superliga de n?quel Inconel 625 atrav?s do processo laser. Uma das desvantagens da deposi??o a laser ou qualquer outro processo de fus?o ? a forma??o de uma regi?o de descontinuidade microestrutural no a?o, chamada de ZTA (zona termicamente afetada pelo calor). Neste estudo, diferentes rotas de tratamentos t?rmicos foram investigadas com o objetivo de eliminar a ZTA e preservar as caracter?sticas originais do substrato e do revestimento.The application of C-Mn steel pipe in the oil & gas industry is quite common since starting of this industry. Even with the great evolution of the metallurgy of this type of steel over the last decades, the challenge is to overcome the corrosion severity caused by sour (H2S, CO2) species present in the petroleum and its derivates. The direct technological solution would be to replace the C-Mn steel by Ni-based superalloys and/or stainless steels. However, the high costs of these materials would make several projects impracticable. In this context, there are several initiatives in order to develop overlay and/or cladding, that means, coatings of C-Mn steels using superalloys and stainless steels. In this work, it was used an overlay deposition of Inconel 625 on the surface of a C-Mn steel using the laser process. A disadvantage of laser deposition, as it is for any deposition melting process, is the formation of a microstructural discontinuity in the steel substrate caused by the thermal cycle (HAZ = heat affected zone). In this study, different heat treatment routes were investigated aiming to eliminate the HAZ preserving the original characteristics of the substrate and of the coating

Quark Number Susceptibility with Finite Chemical Potential in Holographic QCD

We study the quark number susceptibility in holographic QCD with a finite chemical potential or under an external magnetic field at finite temperature. We first consider the quark number susceptibility with the chemical potential. We observe that approaching the critical temperature from high temperature regime, the quark number susceptibility divided by temperature square develops a peak as we increase the chemical potential, which confirms recent lattice QCD results. We discuss this behavior in connection with the existence of the critical end point in the QCD phase diagram. We also consider the quark number susceptibility under the external magnetic field. We predict that the quark number susceptibility exhibits a blow-up behavior at low temperature as we raise the value of the magnetic field. We finally spell out some limitations of our study.Comment: 25 pages, 3 figures, published versio
