A conformação dos espaços públicos do sistema financeiro catarinense (1983 - 2002): um estudo das redes de relações constituídas
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação em Sociologia PolíticaDesde que o Brasil era colônia de Portugal, já se iniciavam propostas para a implementação e constituição de sistemas financeiros em território nacional. O surgimento de instituições financeiras isoladas, principalmente localizadas em redutos mais privilegiados política e economicamente, aos poucos foi dando lugar à disseminação e fortalecimento de estabelecimentos de crédito públicos e privados nas várias unidades da federação. Prioritariamente, o estudo que ora se oferece é resultado de uma busca de compreensão acerca dos mecanismos relacionais que permeiam um espaço de tempo específico do contexto sóciopolítico barrigaverde. Este espaço de tempo principia em março de 1983 e termina em dezembro de 2002. Dentro deste período, a organização administrativa do estado é liderada por Esperidião Amin (dois mandatos), Pedro Ivo Campos, Vilson Kleinübing e Paulo Afonso Vieira. O Sistema Financeiro Público catarinense (SFP), nestas respectivas gestões políticas mencionadas, protagoniza estratégias condizentes com os planejamentos estruturais demandados. Por sua vez, a composição das principais esferas de funcionamento do SFP é preenchida por indivíduos que expressam variadas formas de configuração do aparelho governamental estadual. Since Brazil was a Portuguese possession, at once started suggestions for the implementation and continuation of financials systems in the national territory. The appearance of isolated financials systems mainly located in certain places more privileged politic and economically, by inches was giving place to the dissemination and strengthening of establishments of public and privates credits in the several unities of the federation. In first place, the research that is offered by now is resulted of one search of comprehension circa of the relational mechanisms that permeates from one space of specific time in the #greenbelly# socialpolitic context. This space of time initiates in March 1993 and ends in December 2002. Inside this period, the administrative organization of the state is leaded by Esperidião Amin (two mandates), Pedro Ivo Campos, Vilson Kleinübing and Paulo Afonso Vieira. The Public Financial System (in Portuguese: Sistema Financeiro Público, SFP) of Santa Catarina, in those respective political managements, does suitable strategies with structural planning required. By the way, the composition of the mainly spheres of functioning of the SFP is fulfilled by individuals that expresses varied ways of configuration of the governmental apparatus of the State

Effect of two yeast strains inclusion on the productive performance of piglets challenged with E. coli F4 in the nursery phase
No full textObjetivou-se com esse estudo avaliar duas cepas de levedura Saccharomyces cerevisae, em relação ao desempenho produtivo e aos parâmetros da saúde intestinal de leitões desafiados com E. coli F4. O experimento foi realizado utilizando delineamento em blocos casualizados (peso inicial e sexo) com 12 repetições e quatro tratamentos, assim distribuídos: controle sem desafio (CS), cepa de levedura 1 com desafio (LY1), cepa de levedura 2 com desafio (LY2) e controle desafiado (CD). Foram utilizados 192 leitões (machos castrados e fêmeas) de linhagem genética Choice Genetics, desmamados aos 24 dias, alojados durante a fase de creche, por 42 dias experimentais, divididos em três períodos de acordo com as trocas de ração. As leveduras foram incluídas na dieta em substituição ao material inerte (caulim) durante todo o experimento. No oitavo e nono dia de experimento, os animais desafiados receberam 1 ml de E. coli F4 a uma concentração de 106 UFC. Já no décimo sétimo dia, foram 2 ml a uma concentração de 109UFC. Os animais do tratamento sem desafio receberam a respectiva quantidade de solução salina. Os leitões do tratamento LY1 (P<0,05) apresentaram peso vivo superior em 7%, ganho de peso diário 13% maior, melhor eficiência alimentar em 9,5% e maior consumo de ração diário em 12% nos primeiros 28 dias pós-desmame, quando comparado aos animais CD. No entanto, não houve efeito das cepas de levedura na ocorrência de diarreia pós-desmame, nos parâmetros morfológicos intestinais, no perfil sanguíneo, na composição da microbiota cecal e nas concentrações de ácidos graxos de cadeia curta do conteúdo cecal. Com isso, a inclusão da cepa 1 foi capaz de minimizar os efeitos deletérios associados ao desafio provenientes à inoculação da E. coli nas primeiras semanas de creche.The objective of the present study was to evaluate two strains of Saccharomyces cerevisae yeast, in relation to the productive performance and the intestinal health parameter of piglets challenged with E. coli F4. The experiment was performed using a randomized block design (initial weight and gender) with 12 replicates and four treatments, distributed as follows: control unchallenge (CS), live yeast strain 1 challenge (LY1), live yeast strain 2 challenge (LY2) and control challenge. 192 piglets (barrows and gilts) of Choice Genetics genetic lineage, weaned at 24 days, were evaluated during the nursery phase, for 42 experimental days, it was divided into three periods according to the feed changes. Yeasts were included in the diet as a substitute of the inert material (kaolin) during all the experiment period. On the eighth and ninth day of the experiment, the challenged animals received 1 ml of E. coli F4 at a concentration of 106CFU. On the seventeenth day, it was 2 ml at a concentration of 109CFU. The animals of treatment unchallenged received the respective amount of saline solution. LY1 treatment piglets showed (P<0.05) 7% higher live weight, 13% higher average daily gain, 9.5% better gain-to-feed ratio and 12% higher average daily feed intake in the first 28 days after weaning, when compared to animals CD. However, there was no effect of live yeast strains on the occurrence of post-weaning diarrhea, intestinal morphological parameters, blood profile, cecal microbiota composition and short chain fatty acid concentrations in the cecal content. Thus, the inclusion of strain 1 was able to minimize the deleterious effects associated with the challenge arising from the inoculation of E. coli in the first weeks of day care
Recent results on femtoscopic correlations with the CMS experiment
No full textThe study of femtoscopic correlations in high-energy collisions is a powerful tool to investigate the space-time structure of the particle emitting region formed in such collisions, as well as to probe interactions that the involved particles may undergo after being emitted. An overview of the recent results on the two-particle femtoscopic correlations measurements using charged particles and identified hadrons in pp, pPb, and PbPb collisions at LHC energies is presented. In general, the femtoscopic parameters are obtained assuming a Gaussian or an exponential shape to describe the emitting source distribution. In some cases, however, the generalized Gaussian, i.e., the symmetric alpha-stable L\'evy distribution, is favored to describe the source. Some of the measurements allow to extract the parameters of the strong interaction felt by hadrons using their femtoscopic correlations. The studies are performed in a wide range of the pair average transverse momentum (or average transverse mass) and charged particle multiplicities. In addition, prospects for future physics results using the CMS experiment are also discussed.The study of femtoscopic correlations in high-energy collisions is a powerful tool to investigate the space-time structure of the particle emitting region formed in such collisions, as well as to probe interactions that the involved particles may undergo after being emitted.

Recent Results on Multi-Particle Azimuthal Correlations in High-Multiplicity pp and pPb Collisions in CMS
No full textIn nucleus-nucleus collisions, the Quark-Gluon Plasma behaves like a perfect fluid and the azimuthal anisotropy of the observed particle final-state distributions reflects its properties. This anisotropic flow, arising mainly from initial-state geometry and its fluctuations, highlights the collective behavior of the particles produced in the collision. It is well-described by hydrodynamics and explains the long-range near-side correlations, known as the ridge, observed experimentally in AA collisions and, more recently, in small systems such as pp or pA collisions. The CMS experiment has studied this correlation in details by extracting the momenta of the Fourier decomposition of azimuthal particle-distribution in the final state (, n = 2 - 4). The are extracted using di-hadron correlation and multi-particle cumulant methods in both pp and pPb collisions. In this talk, results from CMS on the ridge in small systems are shown and compared with those in PbPb collisions, demonstrating that the collective nature of the ridge is present also in small systems. The correlation between different Fourier coefficients is further investigated using a symmetric cumulant analysis and compared across colliding systems. The latest results on correlations in pp at 13 TeV and pPb at 8.16 TeV collisions are also discussed. All these results give us a better understanding of collective effects from small to large colliding systems and provide more insights on the nature of the ridge in pp and pPb collisions
Extracting the speed of sound in the strongly-interacting matter created in relativistic nuclear collisions with the CMS experiment
No full textA hot and dense matter exhibiting collective flow behavior with almost no viscous dissipation has been discovered in ultrarelativistic nuclear collisions. To constrain the fundamental degrees of freedom and equation of state of this matter, this talk will present an extraction of its speed of sound using head-on lead-lead collision data collected by the CMS experiment at a center-of-mass energy per nucleon pair of 5.02 TeV. The measurement is based on an analysis of the observed charged multiplicity dependence of the average particle transverse momentum in ultracentral events (impact parameter of nearly zero), a variable which probes the system temperature as a function of entropy density at a fixed volume. Results are compared with hydrodynamic simulations and lattice QCD predictions of the equation of state at high temperatures and small chemical potential. Implications to search for QCD phase transition and the critical point are discussed
Search for extreme electromagnetic fields through measurements of charm meson flow harmonics in PbPb collisions at 5.02~TeV with the CMS detector
No full textIn ultrarelativistic heavy-ion collisions, a very strong (on the order of ) and transient (lifetime on the order of ) electromagnetic (EM) field is expected to be generated inside the medium formed in the collision. This EM field, generated by the collision participants and spectators, is predicted to produce a difference in the harmonics for positive-and negative-charged particles, with the magnetic field mainly responsible for a splitting in rapidity-odd directed flow (), and the Coulomb electric field leading to a charge-dependent splitting in the and average values of emitted particles. Because of their large mass, charm quarks are expected to be created very early in the collision, and thus have more chance of interacting with this strong EM field than light flavor hadrons. In this contribution, measurements of \mathrm{\ensuremath{D^0}} () and \mathrm{\ensuremath{\overline{D}^0}} () mesons
flow harmonics ( and ) are presented as functions of rapidity (), transverse momentum, and collision centrality for PbPb collisions at 5.02 TeV, using the large data samples collected by the CMS experiment during the LHC Run 2. The wide rapidity coverage () of these new charm mesons measurements allow for a better understanding of the 3-dimensional evolution of the medium formed in heavy-ion collisions
Search for narrow high-mass resonances in proton-proton collisions at 8 TeV decaying to a Z and a Higgs boson
No full textWe present the final results of a search in the CMS detector at LHC for high-mass and narrow resonances decaying into a Higgs and a Z SM bosons in the final state with a pair of tau leptons and a pair of quarks. In the resonance mass range of interest 1.0 - 2.5 TeV, the Z and Higgs bosons are produced with large momenta compared with their masses, which implies that the final products of the two quarks or the two taus must be detected within a small angular separation. From a combination of all possible decay modes of the tau lepton, heavy spin-1 resonances production cross sections are excluded at 95 pct C.L. in a range between 0.9 and 27.8 fb, depending on the resonance mass. This analysis is in the context of many searches for heavy resonances decaying into dibosons in the CMS experiment, studying 19.7/fb of integrated luminosity of sqrt(s) = 8 TeV proton-proton collisions
Análise de viabilidade da migração tarifária de consumidores industriais para tarifa branca em conjunto com geração distribuída e banco de baterias
No full textCom o passar dos anos, a energia elétrica, insumo essencial e indispensável no dia a dia da sociedade, vem se tornando cada vez mais onerosa para o consumidor final, principalmente para a indústria, tendo em vista que a fatura de energia está entre os três maiores custos das empresas. Reduzir esse custo é uma ação fundamental, visto que, por consequência, promove uma economia de despesas com produção, gerando maior competitividade no mercado. Para que ocorra essa redução, medidas devem ser adotadas. A troca de modalidade tarifária e a geração distribuída aliada a um sistema de armazenamento são algumas das opções atuais. Com base nisso, este projeto realizou uma análise aplicada a três consumidores industriais do grupo tarifário B, em três cenários distintos a fim de obter os custos com energia elétrica em cada um deles. Os cenários considerados incluíram a utilização da tarifa branca, da geração distribuída e de sistemas de armazenamento por baterias e, ao final, foram comparados os custos de energia em cada um, a fim de encontrar o cenário com menor custo. A conclusão, a partir desses resultados, foi de que a alteração de tarifa convencional para branca reflete em reduções no valor de energia. Porém, o cenário que utiliza geração distribuída para suprimento total do consumo das indústrias apresentou o menor custo de energia. Em relação aos sistemas que utilizam baterias de lítio para armazenamento da energia gerada pelo sistema fotovoltaico, esse apresentou custos de energia menores para aplicação nos períodos intermediário e ponta da tarifa branca em relação à própria tarifa. Os sistemas que utilizam baterias de chumbo-ácido não apresentaram viabilidade de acordo com o propósito do projeto. [resumo fornecido pelo autor]Over the years, electric power, an essential and indispensable input in society's daily life, has become increasingly costly for the end consumer, especially for the industry, considering that the energy bill ranks among the top three costs for businesses. Reducing this cost is a fundamental action as it leads to savings in production expenses, thus generating greater competitiveness in the market. In order to achieve this reduction, measures need to be adopted. Changing tariff modality and distributed generation combined with a storage system are some of the current options. Based on this, this project conducted an analysis applied to three industrial consumers in tariff group B, considering three distinct scenarios in order to obtain the costs of electric power in each of them. The scenarios considered included the use of white tariff, distributed generation, and battery storage systems, and at the end, the energy costs in each scenario were compared to find the one with the lowest cost. The conclusion drawn from these results was that changing from a conventional tariff to a white tariff results in reductions in the energy cost. However, the scenario that utilizes distributed generation to fully supply the industrial consumption presented the lowest energy cost. Regarding systems that use lithium batteries to store the energy generated by the photovoltaic system, they showed lower energy costs for application during the intermediate and peak periods of the white tariff compared to the regular tariff itself. The systems that use lead-acid batteries were not viable according to the project's purpose. [resumo fornecido pelo autor
