Geotermobarometria de granulitos do complexo Juiz de Fora e do grupo Andrel?ndia na regi?o de Abre Campo e Manhua?u, Minas Gerais, Brasil.

Granulitos m?ficos e f?lsicos ortoderivados do Complexo Juiz de Fora e granulitos aluminosos paraderivados do Grupo Andrel?ndia ocorrem na regi?o de Abre Campo e Manhua?u, estado de Minas Gerais. As rochas orto- e paraderivadas est?o tectonicamente intercaladas como resultado da edifica??o do Or?geno Ara?ua? de idade neoproterozoica. Os granulitos m?ficos s?o formados pela associa??o mineral plagiocl?sio + ortopirox?nio + clinopirox?nio ? hornblenda. Os granulitos f?lsicos s?o compostos por plagiocl?sio + quartzo ? feldspato pot?ssico ? ortopirox?nio ? granada. A associa??o mineral dos granulitos aluminosos ? dada por plagiocl?sio + quartzo + granada + biotita ? feldspato pot?ssico ? sillimanita. Os c?lculos utilizando a geotermobarometria convencional e o programa THERMOCALC resultaram em temperaturas entre 748 ?C e 870 ?C e press?es entre 5,7 kbar e 7,5 kbar para o metamorfismo de f?cies granulito que gerou essas rochas durante o desenvolvimento do Or?geno Ara?ua?. A ocorr?ncia local de folia??o milon?tica e de porfiroclastos intensamente deformados ? associada a reativa??o das zonas cisalhamento Manhua?u e Abre Campo durante o escape lateral da por??o sul do or?geno. Esse est?gio ? caracterizado pelo desenvolvimento de grandes zonas de cisalhamento transcorrentes dextrais. A exuma??o dos granulitos do Complexo Juiz de Fora e do Grupo Andrel?ndia est? relacionada ao colapso gravitacional do Or?geno Ara?ua?.Mafic and felsic ortho-derived granulites of the Juiz de Fora Complex and para-derived aluminous granulites of the Andrel?ndia Group occur in the Abre Campo and Manhua?u regions, state of Minas Gerais. The ortho- and para-derived rocks are tectonic intercalated as result of the edification of the neoproterozoic Ara?ua? Orogen. The mafic granulites are formed by the mineral assemblage of plagioclase + orthopyroxene + clinopyroxene ? hornblende. The felsic granulites are composed of plagioclase + quartz + potassium feldspar ? orthopyroxene ? garnet. The mineral assemblage of the aluminous granulites is plagioclase + quartz + garnet + biotite ? potassium feldspar ? sillimanite. Calculations using conventional geothermobarometry and the THERMOCALC software resulted in temperatures between 748 ?C and 870 ?C and pressures between 5.7 kbar and 7.5 kbar for the granulite facies metamorphism related to the development of the Ara?ua? Orogen. The local presence of a mylonitic foliation as well as of intensily deformed porphyroclasts is associated to the reactivation of shear zones as those of Manhua?u and Abre Campo during southward escape of orogen. This stage is characterized for development of large dextral shear zones. The exhumation of granulites of Juiz de Fora Complex and Andrelandia Group are related to the gravitational collapse of the Ara?ua? Orogen

This article presented the procedures of the first stage of the aid business decision making, step-by-step

Perinatal factors associated with developmental defects of enamel in primary teeth: a case-control study

The present study was designed to evaluate associations between developmental defects of enamel (DDE) in the primary dentition and aspects related to mothers and preschoolers in the city of Diamantina, Brazil. A case-control study was carried out involving children aged three to fve years. The case group was composed of 104 children with at least one dental surface affected by DDE. The control group comprised 105 children without DDE, matched for gender and age. The diagnosis of enamel defects was performed using the Developmental Defects of Enamel Index. Information was collected through interviews investigating socio-demographic aspects, gestation, birth weight, prematurity and breastfeeding. Simple and multiple regression analyses were performed, providing unadjusted and adjusted prevalence ratios (Poisson regression). DDE were more prevalent among children who had not been breastfed (PR =?1.57; 95% CI: 1.1?2.2) and those whose mothers were under 24 years of age at the birth of the child (PR =?1.41; 95% CI: 1.1?1.9). The prevalence of DDE in the primary dentition was higher among children who had not been breastfed and those whose mothers were under 24 years of age at the birth of the child

Modelling the diameter distribution of eucalyptus stands using the Gamma function

Neste estudo, avaliou-se o comportamento da fun??o densidade de probabilidade Gama com 2 par?metros para a descri??o da distribui??o diam?trica de um povoamento de eucalipto em diferentes idades. Um modelo de proje??o da distribui??o de di?metros foi constru?do e ajustado aos dados das parcelas permanentes. Os ajustes da fun??o Gama foram avaliados pelo teste de Kolmogorov-Smirnov (KS) e o modelo de distribui??o diam?trica foi avaliado por meio dos coeficientes de determina??o e gr?ficos de res?duos das estimativas geradas pelas equa??es que compuseram o modelo. As distribui??es diam?tricas estimadas pelo sistema de equa??es foram comparadas com as distribui??es observadas pelo teste KS. A maioria dos ajustes apresentou ader?ncia pelo teste KS. O modelo foi capaz de projetar as distribui??es diam?tricas de maneira satisfat?ria, acompanhando a tend?ncia de achatamento da curva da distribui??o em uma sequ?ncia de idades. Conclui-se que a fun??o Gama pode ser utilizada em um modelo de proje??o da distribui??o dos di?metros de povoamentos de eucaliptoFunda??o de Amparo ? Pesquisa do Estado de Minas Gerais (FAPEMIG)Empresa de Pesquisa Agropecu?ria de Minas Gerais (EPAMIG)Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico (CNPq)Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior (CAPES)This study evaluated the behavior of the Gamma probability density function to describe the diameter distribution of eucalyptus stand at different ages. A projection model of the distribution of diameters was constructed and fitted to data from permanent plots. The settings of the Gamma function were assessed by Kolmogorov-Smirnov (KS) test and the diametric distribution model was assessed by the determination coefficients and residual graphs of the estimates generated by the equations that compose the model. The diameter distributions estimated by the system of equations were compared with the distributions observed by the KS test. Most of the adjustments made by the KS test presented adherence. The model was able to design the diameter distributions satisfactorily, following the trend of flattening of the curve of distribution in a sequence of ages. Thus, the Gamma function can be used with statistical efficiency in a projection model of the diameter distribution in eucalyptus stands

It starts with acknowledgement of the regulatory effectiveness of constitution and recognition of the fundamental rights in the civil procedure in order to achieve the constitutionalization of the civil procedure. As a result of this phenomena legislation started being interpreted according to the rules, principles and values original from the constitution. The right of defense, as a dialectical method and fundamental procedural right, recovers special importance in the decision making process. In order to change classic view, restricted to the bilateralism to be heard, the right of defense start to be understood in a new dimension that demands from the judge, allowing the parties to have a democratic and effective participation when defending their rights. This new dimension to the right of defense was considered essencial in this paper. Besides allowing the participation and influence of the parties on the course and the outcomes of the process, the essencial right of defense requires the decisions not to be surprising to the parties, even knowing that this requires the judge?s knowledge. The essencial right of defense is also analysed from its conection point of view and interection with the procedural principles of cooperation, good faith, bounds of the judge to fact of de case, iuria novit curia, rational persuasion and clarification requests. The knowledge of the matter receives form the right of defense guidelines that affirm the participation and influence of the parties on decisions made by the court. Finally, a case study about brasilian precedents was undertaken, aiming to verify the adherence to new dimension brought by the right of defense.Jurisdi??o e do Processo do Programa de P?s-gradua??o em Direito ? Mestrado e tem como objetivo analisar a incid?ncia do contradit?rio no ?mbito do sistema recursal c?vel, particularmente em rela??o aos recursos de apela??o, agravo de instrumento, agravo interno e embargos de declara??o. Parte-se do reconhecimento da efic?cia normativa do texto constitucional e da cataloga??o de direitos fundamentais de cunho processual, para se chegar ao fen?meno da constitucionaliza??o do processo civil. Como reflexo desse fen?meno, a legisla??o infraconstitucional passou a ser interpretada ? luz das regras, dos princ?pios e dos valores emanados pela Constitui??o Federal. O contradit?rio, como m?todo dial?tico e direito fundamental processual, volta a adquirir especial import?ncia na forma??o dos provimentos judiciais. Ao se desprender da vis?o cl?ssica, restrita ao conte?do de bilateralidade da audi?ncia, o contradit?rio passa a ser concebido em uma nova dimens?o que submete igualmente o juiz, permitindo, ?s partes, uma participa??o democr?tica e efetiva no exerc?cio e defesa de seus direitos. No presente estudo, essa nova dimens?o adquirida pelo contradit?rio ? denominada de substancial. Al?m de propiciar a participa??o e a influ?ncia das partes nos rumos e resultado do processo, o contradit?rio substancial imp?e que as decis?es judiciais n?o surpreendam as partes, ainda que se trate de mat?ria de ordem p?blica que imponha, ao juiz, seu conhecimento de of?cio. O contradit?rio substancial tamb?m ? analisado do ponto de vista de sua conex?o e conviv?ncia com os princ?pios processuais da coopera??o, da boa-f? objetiva, da vincula??o do causa, da iuria novit c?ria, da persuas?o racional e com o dever de fundamenta??o das decis?es judiciais. Em um segundo momento do estudo, o contradit?rio ? analisado especificamente no sistema recursal, com corte epistemol?gico nos recursos de apela??o, agravo de instrumento, agravo interno e embargos de declara??o. A cogni??o da mat?ria impugnada recebe, do contradit?rio substancial, diretrizes que asseguram a participa??o e a influ?ncia das partes nas decis?es proferidas pelo ?rg?o ad quem. Por fim, ? realizado um estudo de casos da jurisprud?ncia brasileira, com objetivo de verificar a exist?ncia de ades?o ? nova dimens?o adquirida pelo contradit?rio

Syn-collisional peraluminous magmatism in the Rio Doce region : mineralogy, geochemistry and isotopic data of the Urucum suite (eastern Minas Gerais state, Brazil).

The Urucum Suite granitoids (Rio Doce region, southeastern Brazil) contains four main facies: megafeldspar granites, deformed medium- to coarse-grained granites, tourmaline, and pegmatitic facies. They intrude both the staurolite-garnet-muscovite-biotite schist of the S?o Tom? Formation (Rio Doce Group) and the Galil?ia metaluminous suite (596 ?4 Ma). Detailed structural studies suggest that the Urucum Suite emplaced during an important dextral strike-slip movement (Dl phase) of the Brasiliano orogeny (650-450Ma). Modal and chemical mineralogical variations suggest an evolution from the megafeldspar facies to the pegmatitic facies. Whole-rock geochemistry indicates the peraluminous character of the Urucum Suite granitoids, the evolution from the megafeldspar facies granites to pegmatitic facies granites and suggests the syn-collisional character of this suite. U-Pb zircon (582 ? 2 Ma) and monazite (576-573 ? 4Ma) data indicate that the Urucum Suite emplaced during the Brasiliano orogeny. The peraluminous nature of the Suite and isotopic-rich character in the Rb-Sr (87Sr/86Sr = 0.7114 to 0.7165) and Sm-Nd (eNd = -7.4 and -8.2) systems indicate that it formed by partial melting of older intermediate to felsic crustal sources. Based on early Proterozoic model-ages (2.3 to 1.8 Ga) and on 2.0 Ga U-Pb inherited signature, granitoids of the Suite are probably derived from a rocks with a long crustal residence (Transamazonian basement), without extensive mantle contribution
