In setting up the experiment, the seedlings were separated by size: smaller, medium-sized and larger, so that the implementation of the orchard, there was within each block seedlings with similar vigor. The seedlings of papaya (Carica papaya L.) were prepared, using seeds of papayas hermaphrodites of the cultivar ' Golden Sunrise ', belonging to the soil. On planting and leading between each block, was grown legumes Sunn hemp (Crotalaria juncea) as green manure. The plants were bi-monthly composted manure tanned and potassium sulphate and alternating sprays with foliar fertilizer Agrobio (2%). The phytosanitary control followed the rules of organic farming. Spontaneous herbs were controlled by means of plant cover (Sunn hemp biomass) and periodic ro?adas. It took the experimental design of randomized blocks, being arranged in factorial arrangement of treatments. We evaluated the whole milk concentrations (0,0%, 5% and 10%) + 1% Bordeaux mixture (subplots), in six different breeding densities (1667, 2167, 3167, 2667, 3667 and 4167 plants. hectare-1). Based on the results it is concluded that: the addition of raw cow's milk to the Bordeaux mixture enables greater control of smallpox of papaya, both on the leaves, as in the fruits; the mixture prepared with 10% of raw cow's milk in Bordeaux mixture, the greater the inhibition signs of smallpox from papaya, both on the leaves, as in the fruits; analyzing by vegetative aspect of papaya, the greatest effect of the addition of raw cow's milk in Bordeaux mixture occurs in younger leaves; the extent to which increasing the dosage raw cow's milk, from zero to 10%, in Bordeaux, increases linearly, the ability to control the smallpox of the papaya, both on the leaves, as in the fruits; less degradated plantations allow lower occurrence of smallpox from papaya, both on the leaves, as in the fruits, if compared to those more Caterpillar; the density of plantation of papaya of 1667 plants.ha-4167 plants even 1.ha-1 the severity of smallpox of the papaya tree increases in a linear fashion; smallpox papaya progresses, exponentially, from bottom to top and/or older leaves to the newest; the part of the fruit, stuck in the plant, yet more exposed to external factors, is the most affected by smallpox of papaya, compared with the part facing the stem; analyzing for the papaya reproductive aspect, the greatest effect of the addition of raw cow's milk in Bordeaux is noticed on the face less exposed of the fruit; and, eat avocado with more leaves infected by smallpox will produce fruits also more affected by this disease / O estudo foi conduzido, no Centro Estadual Integrado de Educa??o Rural ? CEIER, situado no munic?pio de ?guia Branca, Regi?o Noroeste do Estado do Esp?rito Santo, o objetivo deste trabalho foi avaliar a a??o do leite integral adicionado ? calda bordalesa no controle do Asperisporium caricae, agente causal da var?ola e o comportamento desta doen?a em diferentes densidades de cultivo do mamoeiro. Na montagem do experimento, as mudas foram separadas por tamanho: menores, m?dias e maiores, de forma que na implanta??o do pomar, houvesse dentro de cada bloco mudas com padr?o de vigor parecido. As mudas de mamoeiro (Carica papaya L.) foram preparadas, utilizando-se sementes de mam?es hermafroditas da cultivar ?Sunrise Golden?, pertencente ao grupo Solo. Na entrelinha de plantio e entre cada bloco, foi cultivada a leguminosa crotal?ria (Crotalaria juncea) como adubo verde. As plantas foram bimensalmente adubadas com esterco curtido e sulfato de pot?ssio e pulveriza??es alternadas, com o biofertilizante l?quido Agrobio (2%). O controle fitossanit?rio seguiu as normas da agricultura org?nica. As ervas espont?neas foram controladas por meio de cobertura vegetal (biomassa da crotal?ria) e de ro?adas peri?dicas. Adotou-se o delineamento experimental de blocos ao acaso, sendo os tratamentos dispostos em parcelas subdivididas. Avaliaram-se as concentra??es de leite integral (0,0%, 5% e 10%) + calda bordalesa 1% (subparcelas), dentro de seis densidades de cultivo diferentes (1667, 2167, 2667, 3167, 3667 e 4167 plantas.hectare-1). Com base nos resultados conclui-se que: a adi??o de leite de vaca cru ? calda bordalesa possibilita maior capacidade de controle da var?ola do mamoeiro, tanto nas folhas, quanto nos frutos; a mistura preparada com 10% de leite de vaca cru na calda bordalesa, propiciou a maior inibi??o dos sinais da var?ola do mamoeiro, tanto nas folhas, quanto nos frutos; analisando pelo aspecto vegetativo do mamoeiro, o maior efeito da adi??o do leite de vaca cru na calda bordalesa ocorre nas folhas mais novas; a medida em que se aumenta a dosagem de leite de vaca cru, de zero at? 10%, na calda bordalesa, aumenta-se, linearmente, a capacidade de controle da var?ola do mamoeiro, tanto nas folhas, quanto nos frutos; plantios menos adensados possibilitam menor ocorr?ncia da var?ola do mamoeiro, tanto nas folhas, quanto nos frutos, se comparados ?queles mais adensados; da densidade de plantio do mamoeiro de 1667 plantas.ha-1 at? 4167 plantas.ha-1 a severidade da var?ola do mamoeiro aumenta de maneira linear; a var?ola do mamoeiro progride, exponencialmente, de baixo para cima e/ou das folhas mais velhas para as mais novas; a parte do fruto, preso ainda na planta, mais exposta aos fatores externos, ? a mais acometida pela var?ola do mamoeiro, se comparado com a parte voltada para o caule da mesma; analisando pelo aspecto reprodutivo do mamoeiro, o maior efeito da adi??o do leite de vaca cru na calda bordalesa ? notado na face menos exposta do fruto; e, mamoeiros com as folhas mais infectadas pela var?ola produzir?o frutos tamb?m mais acometidos por esta doen?a.

Exploring the commonalities between Stanley Hauerwas and James H Cone’s narrative approaches for moral formation for post-Apartheid South Africa

January 2019 (has links)
Doctor Educationis / This thesis will investigate the narrative approach to moral formation by comparing the narrative paradigm as espoused by James H. Cone and Stanley Hauerwas and will apply the findings to post-Apartheid South Africa. I am interested in the extent to which the principles of modernity forms part of the society and the shaping of morality, yet the thesis does not focus on modernity, but on narrative as ideal ethical framework for moral formation. This thesis will look at community, narrative and agency through Stanley Hauerwas’ notion of virtue and James H. Cone’s views of black theology and oppression as means for narrative informed moral formation. This thesis is divided into three major parts. First; an investigation into narrative which includes the arguments made against modernity, narrative and history as it pertains to moral formation and how narrative is understood. Second; James H. Cone and Stanley Hauerwas’ views on narrative and moral formation followed by closer look at Cone and Hauerwas and the critiques of their views. Third; contextualising the findings in a South African context by using the findings in conjunction with South African scholars. The aims are to investigate if moral reform is possible by means of narrative ethics through justice; by means of reconciliation and transformation.

Fe2O3/N Doped rGO Anode Hybridized with NiCo LDH/Co(OH)2 Cathode for Battery-like Supercapacitor

Liu, Huanji, Zhu, Juncheng, Li, Zhong, Shi, Zhicheng, Zhu, Jiliang, Mei, Hua 01 January 2021 (has links)
In this work, a high-performance hybrid supercapacitor is assembled with N-doped reduced graphene oxide (N-rGO) decorated with Fe2O3 (Fe2O3/N-rGO) as the anode, and NiCo layered double hydroxide integrated with conductive Co(OH)2 (NiCo LDH/Co(OH)2) as the cathode. The two main pseudo-capacitive materials are modified by different materials (N-rGO and Co(OH)2) to enhance the conductivity. For anode, the Fe2O3 nanoparticles are uniformly dispersed on N-rGO via a facile solvent-thermal method. The highly conductive Fe2O3/N-rGO exhibits a superior capacitance of 912.9F/g at 1 A/g and retains 84% at 30 A/g. The NiCo LDH/Co(OH)2 cathode also synthesized by a convenient solvent-thermal method delivers a high specific capacitance of 2220.0F/g at 1 A/g and retains 70% at a high current density of 50 A/g. Utilizing these electrodes, we successfully fabricate a hybrid battery-like supercapacitor with an excellent energy density of 103.3 Wh/kg at an outstanding power density of 790 W/kg, an excellent capacitance of 296.3F/g at 1 A/g and a remarkable cyclic stability with 92% retention after 1000 cycles at 10 A/g. Due to the elaborately designed electrode materials, the battery-like supercapacitor exhibits excellent electrochemical properties and is an inspiration for future energy storage devices.

NiCo 10 at%: A promising silicide alternative to NiPt 15 at% for thermal stability improvement in 3DVLSI integration

Deprat, Fabien, Nemouchi, F., Fenouillet-Beranger, C., Batude, P., Previtali, B., Danielou, M., Rodriguez, P., Favier, S., Fournier, C., Gergaud, P., Vinet, M. 22 July 2016 (has links)
3D VLSI with a CoolCube TM process allows vertically stacking several layers of devices with a unique connecting via density above a million/mm2. The thermal budget allowed to process the top transistor is currently limited by NiPt silicide stability of the bottom transistor. To extend the upper transistors thermal process window, Pre-Amorphization Implant (PAI) and Si-Capping were used to improve the stability of NiPt 15% on SiC:P and SiGe 30% :B accesses. While PAI enhances the silicide stability on SiC:P substrate from 600°C 2h to 700°C 2h, neither PAI nor Si-Capping improve silicide stability on SiGe 30% :B. To provide a solution for P accesses stability, NiCo 10% silicidation has been developed. Combined with PAI and Si-Capping, the germano-silicide offers a higher stability (up to 600°C 2h) than its NiPtSi 15% counterpart.

The adoption of the electronic lawsuit model, despite representing a significant reinforcement of the fundamental right to have a lawsuit finished in a reasonable time, thus contributing to its celerity, has been more than a simple tool: it is a significant element of the disruptive evolution of the Civil Procedural Law. The implications of such assimilation includes, among other factors: overcoming the territorial jurisdiction in the face of the deterritorialization phenomenon, due to the ubiquity of the electronic lawsuit system; understanding of a hypertext model which translates into a dynamic way of presenting both the parties? arguments and the content of the decision; possibility of omnidirectional contradictory statement by means of groupware, in an effective community of procedural work; possibility of automated decision-making; and even the appropriation of elements of artificial intelligence for managing juridical information and decisions. Therefore, this thesis focuses on the way through which the electronic lawsuit may be the cause (and also a consequence) of the disruptive evolution of the Civil Procedural Law, without disregarding the criticisms of the model, but rather considering that the environment in which the lawsuit takes place is not neutral, as it both affects and often conditions the message content. / A implanta??o do processo eletr?nico no Brasil decorreu da paulatina assimila??o de instrumentos da inform?tica pelo Poder Judici?rio, que levaram ? iniciativa isolada de diversos tribunais no sentido de desenvolver um sistema operacionalmente funcional e culminaram com a vig?ncia da Lei do Processo Eletr?nico. A ado??o do modelo do processo eletr?nico, embora represente significativa afirma??o do direito fundamental ? dura??o razo?vel do processo, contribuindo para a sua celeridade, traduz-se em mais do que uma mera ferramenta: ? um elemento significativo da evolu??o disruptiva do Processo Civil. As implica??es decorrentes de tal assimila??o envolvem, dentre outros fatores: a supera??o da compet?ncia territorial diante do fen?meno da desterritorializa??o, pela ubiquidade do processo eletr?nico; a compreens?o de um modelo de hipertexto, que se traduza numa forma din?mica de apresenta??o dos argumentos das partes e do conte?do decis?rio; a possibilidade do contradit?rio omnidirecional, por meio do groupware, numa efetiva comunidade de trabalho processual; a possibilidade de automa??o dos atos decis?rios; e mesmo a apropria??o de elementos da intelig?ncia artificial na manipula??o das informa??es e decis?es jur?dicas. A tese, assim, presta-se a abordar como e de que forma ? poss?vel que o processo eletr?nico represente a causa (e tamb?m a consequ?ncia) da evolu??o disruptiva do Direito Processual Civil, sem desconsiderar as cr?ticas ao modelo, mas considerando-se que o meio no qual se desenvolve o processo n?o ? neutro, pois afeta e, muitas vezes, condiciona o conte?do da mensagem.

Folha de S?o Paulo: o di?rio oficial do grande irm?o / Folha de S. Paulo - The Big Brother?s Oficial Daily

No. of bitstreams: 1 EmanoelFPBpdf.pdf: 1963954 bytes, checksum: 58f95f790e43b511ad865076db6bbcfb (MD5) Previous issue date: 2009-08-21 / This project wants to analyze the newspaper like a collective organic intellectual thing, and its action like a conservator integral journalism, it makes it looks like a politics block. In this case, the newspaper inserts itself in a process to support the dominated fundamental class. In the same time, it searches to disqualify politically, using the news and the opinion, the sprouting of against-hegemony even untimely and distant in the historical time. Facing this proposal we take as study object the FOLHA DE S. PAULO, nowadays the most representative agency of the great conservative press. Our theoretical reference takes as base the Gramsci organic intellectual formularizations, hegemony, position?s war, integral journalism and private device of hegemony. We allow ourselves, in a subsidiary way to the Gramsci basement, using the novel 1984 written by George Orwell, as a method to explicit, in a comparative way, the manipulation of the reality by the newspaper in its activity of collective organic intellectual. The ideology is the heuristic connection point to make convergence between reality and fiction. For the intended evidences we develop analysis of the daily covering about two great accidents occurred in 2007: The landslide of part of the workmanships of the tunnel of the Companhia do Metropolitano de S?o Paulo-Metr? (line yellow 4). And the flying disaster involving the airbus of Transportes A?reos Meridionais-TAM, flight 3054, also in that state. In the first accident we find endorsement of the newspaper to the S?o Paulo?s government, in the person of the politician actor Jos? Serra (PSDB), representative of the conservative forces and responsible for the workmanships of the Subway, to who it tried to distance politically of the fact. In the second event, the opposition to the politician actor Luis In?cio Luis Lula da Silva and his politics block, the PT, as a possibility against-hegemonic contested, being the mentioned actor appointed as responsible for the occurrence. However, the newspaper says that it is independent and direct, and this direct action comes from the environment. In this environment, the diversity of conceptions of world would guide the publishing work, making the FOLHA DE S. PAULO to take it as a reference for the intended objective, hiding the politics block militancy / Este trabalho objetiva analisar o jornal como intelectual org?nico coletivo cujo agir, no exerc?cio de jornalismo integral conservador, o assemelha doutrinariamente a partido pol?tico. No caso em apre?o, jornal que se insere em processo de apoio a classe fundamental dominante ao mesmo tempo em que busca desqualificar politicamente, via notici?rio e opini?o, surgimento de contra-hegemonia mesmo que tardia e distante no tempo hist?rico. Frente a tal proposta tomamos como objeto de estudo a FOLHA DE S. PAULO, hoje o mais representativo ?rg?o da grande imprensa conservadora. Nosso referencial te?rico toma como base as formula??es gramscianas intelectual org?nico, hegemonia, guerra de posi??o, jornalismo integral e aparelho privado de hegemonia. Permitimo-nos, de forma subsidi?ria ao embasamento gramsciano, o uso de obra liter?ria, a novela 1984, de George Orwell, como meio de explicitar metaforicamente a manipula??o do real pelo jornal em sua atividade de intelectual org?nico coletivo. A ideologia ? o ponto nodal heur?stico a fazer converg?ncia entre realidade e fic??o. Para as constata??es pretendidas desenvolvemos an?lise da cobertura do di?rio, relativa a dois grandes acidentes ocorridos em 2007: o desabamento de parte das obras do t?nel da Companhia do Metropolitano de S?o Paulo - Metr? (linha 4-amarela). E desastre aviat?rio envolvendo airbus da Transportes A?reos Meridionais - TAM, v?o 3054, tamb?m naquele estado. No primeiro acidente encontramos respaldo do jornal ao governo paulista, na pessoa do ator pol?tico Jos? Serra (PSDB), representante das for?as conservadoras e respons?vel pelas obras do Metr?, mas a quem se buscou distanciar politicamente do fato. No segundo acontecimento, manifesta??o oposicionista ao ator pol?tico Luis In?cio Lula da Silva e a seu partido, o PT, como possibilidade contra-hegem?nica contestada, sendo o mencionado ator apontado como respons?vel direto pelo ocorrido. Todavia, o jornal afirma-se como n?o partid?rio e objetivo, sendo tal objetividade advinda do mercado. Neste, a diversidade de concep??es de mundo orientaria o trabalho editorial, levando a FOLHA DE S. PAULO a tom?-lo como referente v?lido para a pretendida objetividade, ocultando assim a milit?ncia partid?ria

These cells then start to express -SMA, a marker that can be used for their identification. Studies suggest that myofibroblasts are related to the aggressiveness of different tumors and that TGF-1 and IFN- play a role in myofibroblast differentiation, stimulating or inhibiting this differentiation, respectively. The objective of this study was to investigate the role of myofibroblasts in epithelial odontogenic tumors, correlating the presence of these cells with the aggressiveness of the tumor. Immunohistochemistry was used to evaluate the expression of TGF-1 and IFN- in myofibroblast differentiation, as well as the expression of MMP-13, which is activated by myofibroblasts, and of EMMPRIN (extracellular matrix metalloproteinase inducer) as a precursor of this MMP. The sample consisted of 20 solid ameloblastomas, 10 unicystic ameloblastomas, 20 odontogenic keratocysts, and 20 adenomatoid odontogenic tumors. For evaluation of myofibroblasts, anti- -SMA-immunoreactive cells were quantified in connective tissue close to the epithelium. Immunoexpression of TGF-1, IFN-, MMP-13 and EMMPRIN was evaluated in the epithelial and connective tissue components, attributing scores of 0 to 4. The results showed a higher concentration of myofibroblasts in solid ameloblastomas (mean of 30.55), followed by odontogenic keratocysts (22.50), unicystic ameloblastomas (20.80), and adenomatoid odontogenic tumors (19.15) (p=0.001). No significant correlation between TGF-1 and IFN- was observed during the process of myofibroblast differentiation. There was also no correlation between the quantity of myofibroblasts and MMP-13 expression. Significant correlations were found between MMP-13 and TGF-1 (r=0.087; p=0.011), between MMP- 13 and IFN- (r=0.348; p=0.003), as well as between EMMPRIN and MMP-13 (r=0.474; p<0.001) and between EMMPRIN and IFN- (r=0.393; p=0.001). The higher quantity of myofibroblasts observed in solid ameloblastomas, odontogenic keratocysts and unicystic ameloblastomas suggests that these cells are one of the factors responsible for the more aggressive biological behavior of these tumors, although the myofibroblast population was not correlated with TGF-1, IFN-, MMP-13 or EMMPRIN. The correlation between MMP- 13 and TGF-1 suggests that the latter induces the expression of this metalloproteinase. The present results also support the well-established role of EMMPRIN as an inducer of MMP-13. Furthermore, the relationship between EMMPRIN and IFN- and between MMP-13 and IFN- suggests synergism in the antifibrotic effect of these markers / Os miofibroblastos s?o c?lulas que apresentam um fen?tipo h?brido exibindo caracter?sticas morfol?gicas de fibroblastos e de c?lulas musculares lisas, sendo a aquisi??o de tal fen?tipo denominada diferencia??o, passando ent?o a expressar a -SMA, a qual ? importante na identifica??o dessas c?lulas. Estudos t?m sugerido que os miofibroblastos apresentam rela??o com a agressividade de diversas les?es e que o seu processo de diferencia??o estaria relacionado ? express?o do TGF- 1 e do IFN- atuando, respectivamente, no est?mulo e na inibi??o dessa diferencia??o. O objetivo deste trabalho foi investigar o papel dos miofibroblastos em les?es odontog?nicas epiteliais, relacionando-os ? agressividade das les?es e analisar por meio da imuno-histoqu?mica, a express?o do TGF- 1 e IFN- no processo de diferencia??o, al?m da an?lise da MMP-13 que ? ativada por miofibroblastos e do indutor de metaloproteinases de matriz (EMMPRIN) como precursor desta MMP. A amostra foi constitu?da por 20 ameloblastomas s?lidos, 10 ameloblastomas unic?sticos, 20 ceratocistos odontog?nicos e 20 tumores odontog?nicos adenomat?ides. Para a avalia??o dos miofibroblastos, foram quantificadas as c?lulas imunorreativas ao anticorpo - SMA presentes no tecido conjuntivo, pr?ximo ao tecido epitelial. As express?es de TGF- 1, IFN- , MMP-13 e EMMPRIN, foram avaliadas no componente epitelial e no conjuntivo, estabelecendo-se o percentual de imunorreatividade e atribuindo-se escores de 0 a 4. A an?lise dos miofibroblastos evidenciou maior concentra??o nos ameloblastomas s?lidos (m?dia de 30,55), seguido pelos ceratocistos odontog?nicos (22,50), ameloblastomas unic?sticos (20,80) e tumores odontog?nicos adenomat?ides (19,15) com valor de p= 0,001. N?o foi encontrada correla??o significativa entre TGF- 1 e IFN- no processo de diferencia??o dos miofibroblastos, bem como na rela??o entre a quantidade de miofibroblastos e a express?o da MMP-13. Constatou-se, correla??o estat?stica entre MMP-13 e TGF- 1 (r= 0,087; p= 0,011) al?m de significante correla??o entre MMP-13 e IFN- (r=0,348; p=0,003). Entre EMMPRIN e MMP-13 verificou-se signific?ncia (r= 0,474; p<0,001) assim como entre EMMPRIN e IFN- (r=0,393; p=0,001). A maior quantidade de miofibroblastos evidenciada nos ameloblastomas s?lidos, ceratocistos odontog?nicos e ameloblastomas unic?sticos sugere que estas c?lulas podem ser um dos fatores respons?veis para um comportamento biol?gico mais agressivo destas les?es, embora a popula??o de miofibroblastos n?o tenha apresentado correla??o com TGF- - 1, IFN- ,MMP-13 e EMMPRIN. Quanto a correla??o evidenciada entre MMP-13 e TGF- 1, isto pode sugerir um papel indutor do TGF- 1 para a express?o da MMP-13, assim como os resultados deste estudo refor?am a rela??o bem estabelecida do EMMPRIN como indutor da MMP-13. Constatou-se tamb?m rela??o entre EMMPRIN e IFN- assim como entre MMP-13 e IFN- sugerindo, dessa forma, um sinergismo na a??o anti-fibr?tica desses marcadores

The theoretical model is based on the Heisenberg Hamiltonian in the exchange regime, together with the powerful transfer matrix method, and taking into account the RPA approximation. The magnetic materials considered are simple cubic ferromagnets. Our main interest in this study is to investigate the effects of quasiperiodicity on the physical properties of the systems mentioned by analyzing the behavior of spin wave propagation through the dispersion and transmission spectra of these structures. Among of these results we detach: (i) the fragmentation of the bulk bands, which in the limit of high generations, become a Cantor set, and the presence of the mig-gap frequency in the spin waves transmission, for generalized Fibonacci sequence, and (ii) the strong dependence of the magnonic band gap with respect to the parameters k, which determines the amount of different magnetic materials are present in quasicrystal, and n, which is the generation number of the sequence k-component Fibonacci. In this last case, we have verified that the system presents a magnonic band gap, whose width and frequency region can be controlled by varying k and n. In the exchange regime, the spin waves propagate with frequency of the order of a few tens of terahertz (THz). Therefore, from a experimental and technological point of view, the magnonic quasicrystals can be used as carriers or processors of informations, and the magnon (the quantum spin wave) is responsible for this transport and processing / Neste trabalho investigamos espectros de estruturas de banda e de transmit?ncia em quasicristais magn?nicos que apresentam as chamadas desordens determin?sticas, especificamente, sistemas de multicamadas magn?ticas que s?o constru?dos obedecendo as sequ?ncias substitutionais de Fibonacci generalizada (apenas os casos golden mean (GM), silver mean (SM), bronze mean (BM), copper mean (CM) e nickel mean (NM)) e k-componente de Fibonacci. O modelo te?rico ? baseado no hamiltoniano de Heisenberg para o regime de troca, juntamente com o poderoso m?todo da matriz transfer?ncia, e levando em conta a aproxima??o RPA. Os materiais magn?ticos considerados s?o ferromagnetos c?bicos simples. O principal interesse deste estudo ? investigar o efeito da quasi-periodicidade nas propriedades f?sicas dos sistemas citados analisando o comportamento da propaga??o de ondas de spin por meio dos espectros de dispers?o e de transmiss?o dos magnons nestas estruturas. Entre os resultados destacamos: (i) a fragmenta??o das bandas de volume que, no limite de altas gera??es, se tornam conjuntos de Cantor, e a presen?a da frequ?ncia de mid-gap na transmit?ncia das ondas de spin, na sequ?ncia de Fibonacci generalizada; e (ii) a forte depend?ncia do band gap magn?nico com rela??o aos par?metros k, que determina a quantidade de materiais magn?ticos diferentes presentes no quasi-cristal, e n, que ? o n?mero da gera??o da sequ?ncia k-componente de Fibonacci. Neste ?ltimo caso, verificamos que o sistema apresenta uma banda magn?nica proibida, cuja largura e regi?o de frequ?ncia podem ser controladas variando k e n. No regime de troca, as ondas de spin propagam-se com frequ?ncia da ordem de algumas dezenas de terahertz (THz). Portanto, do ponto de vista experimental e tecnol?gico, os quasi-cristais magn?nicos podem ser utilizados como transportadores ou processadores de informa??es, sendo o magnon (o quantum da onda de spin) o respons?vel por esse transporte e processamento

It is known that changes in age structure and the consequences of population aging increase the prevalence of chronic degenerative diseases, a process that leads to an increase in costs for health systems. The main purpose of this study was to associate costs of elderly hospitalizations with mean per capita household income in elderly's municipality of residence. The method was a cross-sectional study that assessed hospitalizations of elderly people living in the municipalities of Alvorada, Ivoti and Porto Alegre, Southern Brazil, and admitted at hospitals in the state of Rio Grande do Sul in 2011, based on data collected from SIH/SUS-DATASUS, a database created by the Brazilian Ministry of Health. These municipalities were selected for this study because they showed the greatest disparity in mean per capita household income among the municipalities belonging to their Regional Health Department. Using the tabulation tool named TABWIN, the following analysis parameters were selected: total number, frequency and length of hospitalizations. Such data were associated with socioeconomic and demographic data of the municipalities under study. Considering the overall amount of hospitalizations of elderly people living in the three municipalities analyzed, it was observed that inhabitants of Porto Alegre showed the lowest frequency of hospitalizations (11.15%), whereas their hospitalizations had the highest mean cost (1.896,19 BRL [Brazilian reais]). Inhabitants of Ivoti showed the highest frequency of hospitalizations (18.53%), with the lowest mean cost (R$ 1,001.10 BRL), whereas inhabitants of Alvorada had an intermediate frequency of hospitalizations (16.57%), with a mean cost of R$ 1,483.66 BRL. As for the association between healthcare costs and mean household income, Porto Alegre showed the highest income (1,722.37 BRL) and the highest per capita gross internal product (GDP), Ivoti had intermediate income (1,019.75 BRL) and per capita GDP, and Alvorada presented a significantly lower income (587.84 BRL). However, although Porto Alegre showed the highest per capita cost with hospitalization of its inhabitants (31.78 BRL), it assigned only 0.1% of its GDP to cover these expenses, whereas Alvorada had a per capita cost of 22.08 BRL, assigning 0.29% of its per capita GDP, and Ivoti showed the lower cost per capita (18.94 BRL) for covering elderly hospitalizations and also the lowest portion of its GDP per capita for this purpose (0.08%). The combination of demographic, socioeconomic, epidemiological, and morbidity and mortality data provides a more solid, critical and endorsed view for the construction of favorable or unfavorable opinions regarding health actions and the use of public resources. Additionally, it is important to develop data analysis and collection skills among health professionals and managers, in order to potentiate care so that it meets the actual needs of each municipality or region during decision making processes. / O crescente envelhecimento da popula??o vem trazendo consigo modifica??es das necessidades na organiza??o social em que vivemos, exigindo desde uma melhor compreens?o desta transi??o epidemiol?gica at? as quest?es financeiras que envolvem o custeio desta longevidade. Entende-se que as mudan?as na estrutura et?ria e as consequ?ncias do envelhecimento populacional tornam mais significativa a preval?ncia de doen?as cr?nico-degenerativas, processo esse que desencadeia crescentes custos para os sistemas de sa?de. Este trabalho teve como objetivo relacionar custos de interna??es hospitalares de idosos com a renda m?dia domiciliar per capita de seus munic?pios de resid?ncia. Trata-se de um estudo transversal com an?lise a partir dos elementos colhidos no banco de dados do SIH/SUS-DATASUS, de interna??es hospitalares de idosos residentes dos munic?pios de Alvorada, Ivoti e Porto Alegre, internados no ano de 2011 em hospitais do Rio Grande do Sul, selecionados por representarem a maior disparidade de renda m?dia domiciliar per capita, dentre os munic?pios de sua Coordenadoria Regional de Sa?de. Atrav?s do TABWIN foram selecionados como par?metros para as an?lises o valor total, frequ?ncia e tempo de perman?ncia das interna??es hospitalares. Tais dados foram relacionados aos dados socioecon?micos e demogr?ficos dos munic?pios em estudo. Considerando o montante global de todas as interna??es dos idosos residentes dos tr?s munic?pios em an?lise, verificou-se que os mun?cipes de Porto Alegre apresentaram a menor frequ?ncia de interna??es (11,15%), ao passo que suas interna??es obtiveram o maior custo m?dio (R$ 1.896,19). Os mun?cipes de Ivoti apresentaram a maior frequ?ncia de interna??es, no valor de 18,53%, com o menor custo m?dio, de R$ 1.001,10, enquanto que os de Alvorada apresentaram interna??es em frequ?ncia intermedi?ria (16,57%), com custo m?dio de R$ 1.483,66. Quanto ? rela??o de custos em sa?de com renda m?dia domiciliar per capita, Porto Alegre apresentou a maior renda (R$ 1.722,37) e o maior PIB per capita, Ivoti apresentou renda R$ 1.019,75 e PIB intermedi?rios e Alvorada apresentou a renda significativamente menor (R$ 587,84). Entretanto, apesar de Porto Alegre ter apresentado o maior custo per capita com as interna??es de seus mun?cipes (R$ 31,78), empenhou apenas 0,1% de seu PIB para suprir estes custos, enquanto o munic?pio de Alvorada apresentou custo per capita de R$ 22,08, empenhando 0,29% de seu PIB per capita, e Ivoti apresentou o menor custo per capita (R$ 18,94) para a cobertura de interna??es de seus idosos e tamb?m teve o menor consumo de seu PIB per capita com este objetivo (0,08%). O cruzamento de dados demogr?ficos, socioecon?micos, epidemiol?gicos e de morbimortalidade proporciona uma vis?o mais s?lida, cr?tica e respaldada para a constru??o de pareceres favor?veis ou desfavor?veis ?s a??es de sa?de e ? utiliza??o dos recursos p?blicos. Tamb?m o maior desenvolvimento da habilidade de coleta e an?lise desses dados ? algo que merece ser disseminado entre os profissionais e gestores em sa?de, em prol da potencializa??o do atendimento ?s reais necessidades de cada munic?pio ou regi?o durante processos decis?rios.
