Efeito do comprimento de estacas herbáceas de dois clones de umezeiro (Prunus mume Sieb & Zucc.) no enraizamento adventício

O umezeiro (Prunus mumeSieb & Zucc.) é uma rosácea de folhas caducas, nativa da China, cujos frutos e flores são muito apreciados pelos povos orientais. No Brasil, alguns estudos foram realizados visando a sua utilização como porta-enxerto para pessegueiro e nectarineira, dadas as suas características de adaptação, rusticidade, redução do porte da planta e compatibilidade com algumas cultivares de Prunus persica. O presente estudo foi conduzido em câmara de nebulização sob ripado, pertencente ao Departamento de Produção Vegetal da FCAV/UNESP, Câmpus de Jaboticabal-SP. Objetivou-se verificar a influência de quatro comprimentos de estacas herbáceas no enraizamento de dois clones de umezeiro. O material vegetal, identificado como Clone 10 e Clone 15, foi oriundo do Programa de Melhoramento Genético do Instituto Agronômico de Campinas-SP. O experimento foi constituido de fatorial 2 x 4, em blocos casualizados, sendo o fator clone em 2 níveis (Clone 10 e Clone 15) e o fator comprimento de estaca em 4 níveis (12; 15; 18 e 25cm). Pelos resultados observados, verificou-se diferença entre os clones somente na porcentagem de estacas brotadas e número de raízes por estaca. O comprimento da estaca influenciou na porcentagem de enraizamento e na mortalidade das estacas, sendo que estacas maiores tenderam a apresentar maiores porcentagens de enraizamento e menores de mortalidade. As estacas com 12cm, embora apresentando menor número de raízes por estaca, são recomendadas por permitirem a obtenção de um maior número de estacas por planta-matriz. Houve efeito significativo da interação entre os fatores para número e comprimento de raízes.

Enraizamento de estacas herbáceas de quatro clones de umezeiro (Prunus mume Sieb. et Zucc.) durante o inverno ameno, em Jaboticabal-SP

Estudos realizados no Brasil com o umezeiro (Prunus mume Sieb. et Zucc.) relatam promissoras perspectivas de utilização desta espécie como porta-enxerto para pessegueiro e nectarineira, em função de sua rusticidade, adaptação ao inverno brando, compatibilidade com Prunus persica, redução do vigor das plantas e melhoria da qualidade dos frutos. Entretanto, em função da propagação por sementes, tem sido observadas diferenças de vigor entre as plantas, resultando em pomares muito heterogêneos. Assim, o presente estudo teve por objetivo estudar o enraizamento de estacas herbáceas de quatro clones de umezeiro (Clones 02, 05, 10 e 15) durante o inverno ameno, em Jaboticabal-SP. O experimento foi conduzido entre os meses de junho e agosto, sendo avaliado aos 70 dias após a estaquia. Pelos resultados obtidos, foi possível concluir que é viável a propagação dos clones estudados por enraizamento de estacas herbáceas durante o inverno. Foram observadas diferenças entre os clones quanto à porcentagem de enraizamento, porcentagem de estacas com calo, número e comprimento das raízes. No conjunto das variáveis analisadas, os melhores resultados foram obtidos com os Clones 10 e 15.

Enxertia em plantas de pimentão no controle da murcha de fitóftora em ambiente protegido

Avaliou-se a viabilidade de utilização da enxertia em plantas de pimentão (Capsicum annuum, L.), visando o controle da murcha de fitóftora. A pesquisa foi conduzida de setembro de 2000 a julho de 2001, na UNESP, Botucatu, em ambiente protegido. Adotou-se o delineamento experimental de blocos ao acaso, com 4 repetições e 5 plantas por parcela. Foram utilizados dois porta-enxertos resistentes a Phytophthora capsici, híbridos F1 de Capsicum annuum, e três híbridos comerciais suscetíveis (Elisa, Margarita e Magali-R). A enxertia foi realizada quando porta-enxertos e enxertos apresentavam respectivamente sete e três folhas verdadeiras, pelo método de garfagem fenda simples. Aos 14 dias após o transplante das mudas foi feita a inoculação do fungo, utilizando sementes de trigo infestadas pelo patógeno, depositadas ao redor do colo da planta. Quatro dias após a inoculação, e a partir daí a cada 15 dias, foram feitas avaliações que confirmaram a resistência dos porta-enxertos e a suscetibilidade das plantas não enxertadas. Observou-se bom nível de compatibilidade de enxertia em todas as combinações, precocidade de florescimento das plantas não enxertadas, manutenção de resistência à doença pelas plantas enxertadas durante todo o período e variações na altura das plantas em algumas combinações. Com relação à produção, verificou-se que os frutos mantiveram as características fenotípicas de cada híbrido, revelando que não houve interferência dos porta-enxertos neste aspecto. Concluiu-se haver viabilidade técnica de utilização da enxertia no controle da murcha de fitóftora em ambiente protegido.

Estudo das propriedades físico-químicas do biodiesel e suas influências na deterioração dos elastômeros aplicados no sistema de injeção dos motores diesel

The biodiesel use has become important due to its renewable character and to reduce environmental impacts during the fuel burning. Theses benefit will be valid if the fuel shows good performance, chemistry stability and compatibility with engines. Biodiesel is a good fuel to diesel engines due to its lubricity. Then, the aimed of this study was to verify the physicalchemistry properties of biodiesel and their correlations with possible elastomers damage after biodiesel be used as fuel in an injection system. The methodology was divided in three steps: biodiesels synthesis by transesterification of three vegetable oil (soybean, palm and sunflower) and their physical-chemistry characterization (viscosity, oxidative stability, flash point, acidity, humidity and density); pressurized test of compatibility between elastomers (NBR and VITON) and biodiesel, and the last one, analyze of biodiesels lubricity by tribological test ball-plan( HFRR). Also, the effect of mixture of biodiesel and diesel in different concentrations was evaluated. The results showed that VITON showed better compatibility with all biodiesel blends in relation to NBR, however when VITON had contact with sunflower biodiesel and its blends the swelling degree suffer higher influences due to biodiesel humidity. For others biodiesels and theirs blends, this elastomer kept its mechanical properties constant. The better tribological performance was observed for blends with high biodiesel concentration, lower friction coefficient was obtained when palm biodiesel was used. The main mechanisms observed during the HFRR tests were abrasive and oxidative wear

Avaliação mecânica e microestrutural de compósitos de poliéster com adição de cargas minerais e resíduos industriais

With the current growth in consumption of industrialized products and the resulting increase in garbage production, their adequate disposal has become one of the greatest challenges of modern society. The use of industrial solid residues as fillers in composite materials is an idea that emerges aiming at investigating alternatives for reusing these residues, and, at the same time, developing materials with superior properties. In this work, the influence of the addition of sand, diatomite, and industrial residues of polyester and EVA (ethylene vinyl acetate), on the mechanical properties of polymer matrix composites, was studied. The main objective was to evaluate the mechanical properties of the materials with the addition of recycled residue fillers, and compare to those of the pure polyester resin. Composite specimens were fabricated and tested for the evaluation of the flexural properties and Charpy impact resistance. After the mechanical tests, the fracture surface of the specimens was analyzed by scanning electron microscopy (SEM). The results indicate that some of the composites with fillers presented greater Young s modulus than the pure resin; in particular composites made with sand and diatomite, where the increase in modulus was about 168 %. The composites with polyester and EVA presented Young s modulus lower than the resin. Both strength and maximum strain were reduced when fillers were added. The impact resistance was reduced in all composites with fillers when compared to the pure resin, with the exception of the composites with EVA, where an increase of about 6 % was observed. Based on the mechanical tests, microscopy analyses and the compatibility of fillers with the polyester resin, the use of industrial solid residues in composites may be viable, considering that for each type of filler there will be a specific application

As construções adverbiais em mente: análise funcionalista e implicações para o ensino de língua materna

This research aims at investigating the constructions with adverbials in ly, based on the view of contemporaneous linguistic functionalism, such as proposed by Givón, Hopper, Thompson, Traugott, Furtado da Cunha, as well as the cognitivist notion of language, through construction grammar support upon the patterns of Goldberg and the prototypes theory. The cognitive functional approach adopted here considers the change as a proper and inherent phenomenon of language and understands the linguistic phenomenon as resulting from effective use of language. Another aspect to be considered to the realization of this study is the fact that the formation adjective + ly is a word construction mechanism really productive, which generates interests on linguistic description. In a particular way, our leading objective is to exam the constructions with adverbials in ly in the context of language in use, in its oral and written forms, looking for to apprehend the meaning multiple manifestations forged in the use. Bearing this in mind, we worked with data from the Corpus Discurso & Gramática (Natal). There are, in the data, adverbs ended in ly that take the signification of mode, as foreseen in traditional models, but there are also other significations, for instance, the modalizador in its different manifestations. The results show that this adverb is a linguistic mark that carries in its constitution the multissêmico and multifunctional character, which interferes extremely in the ordination of this category, assuming a position sometimes pre-verbal, sometimes post-verbal. Other aspect observed refers to the relationship between the adverb and the verb, with emphasis on the compatibility or restriction between them, option which is related to the semantic aspect. The data in analysis legitimate the use in different constructions with adverb ended in ly in various genres, as follows: personal experience narrative, retold narrative, local description, proceeding account, opinion account, both in oral as in written language

Avaliação do programa de tutorização da EMATER-RN para servidores em estágio probatório

The present thesis evaluated the contributions and limitations of the tutorship program introduced in EMATER-RN, as a tactic of organizational socialization for civil servants in probationary stage. Tutorship was understood as an intensive and continuous relational process, in which a more experienced person in the organization the tutor offers psychosocial support, stimulates the development of the professional career and enables to the newcomer the tutee learning on job performance. The organizational socialization was considered in the perspective of the symbolic interactionism. The study was characterized as a program evaluation and as an action research. The practical interventions for the program implementation were conducted and, at the same time, the evaluations of process, results and reaction to the program were applied. Among the major contributions of the action research, it stood out: the diagnosis of reasons for the formation of the pair and of expectations of tutors and tutees, the improvement of the tutorship registration tools, the ascertainment of the success of the program in the socialization of the new civil servants, the confirmation of the importance of the compatibility among them and of the adequate performance of tutorship functions for achieving its benefits. Based in constraints of the program, one may quote as essential recommendations: the formation of a technical team supporting the program, the clear establishment of deadlines for each procedure and the reinforcement to its compliance, the investigation of the functions performed by the tutor, the sensitization of the managers to the resolution of problems that affect the program, the voluntary participation of the tutor and the continuous meetings of tutors and tutees. One settles for the relevance of the program and in favor of its continuation, provided that its improvement and systematic management are conducted.

Tratamento eletroquímico de água produzida sintética para remoção de hidrocarbonetos policíclicos aromáticos

The aim of this work is the treatment of produced water from oil by using electrochemical technology. Produced water is a major waste generated during the process of exploration and production in the oil industry. Several approaches are being studied aiming at the treatment of this effluent; among them can be cited the biological process and chemical treatments such as advanced oxidation process and electrochemical treatments (electrooxidation, electroflotation, electrocoagulation, electrocoagulation). This work studies the application of electrochemical technology in the treatment of the synthetic produced water effluent through the action of the electron, in order to remove or transform the toxic and harmful substances from the environment by redox reactions in less toxic substances. For this reason, we used a synthetic wastewater, containing a mixture H2SO4 0,5M and 16 HPAs, which are: naphthalene, acenaphthylene, acenaphthene, fluorene, phenanthrene, anthracene, fluoranthene, pyrene, benzo (a) anthracene, chrysene, benzo(b)fluoranthene, benzo(k) fluoranthene, benzo(a)pyrene, indeno(1,2,3-cd)pyrene, dibenzo(a, h)anthracene, benzo(g, h, i)perylene. Bulk electrochemical oxidation experiments were performed using a batch electrochemical reactor containing a pair of parallel electrodes, coupled with a power supply using a magnetic stirrer for favoring the transfer mass control. As anodic material was used, a Dimensionally Stable Anode (DSA) of Ti/Pt, while as cathode was used a Ti electrode. Several samples were collected at specific times and after that, the analysis of these samples were carried out by using Gas Chromatography Coupled to Mass Spectrometry (GC - MS) in order to determine the percentage of removal. The results showed that it was possible to achieve the removal of HPAs about 80% (in some cases, more than 80%). In addition, as an indicator of the economic feasibility of electrochemical treatment the energy consumption was analyzed for each hour of electrolysis, and based on the value kWh charged by ANEEL, the costs were estimated. Thus, the treatment costs of this research were quite attractive

Desenvolvimento de misturas ternárias para remoção de reboco de fluido de perfuração sintético

The construction of wells is one of the most important activities of the oil industry. The drilling process is the set of activities and operations to design, program and perform the opening thereof. During this process, the cuttings are removed by the drilling fluid, or mud, and carted to the surface. This fluid is injected into the drill string and returns to the surface through the annular space between the well walls and the drill string. After the descent of the column casing, the annular space between the casing string and the walls of the borehole is filled with cement so as to secure the spine and prevent any migration of fluids between the various permeable zones traversed by the well behind of the coating. To ensure the good quality of the cementation scrubbers are used mattresses which are pumped ahead of the cement slurry so as to avoid contamination of the drilling fluid paste, or vice versa, and assist in the removal of plaster, formed by drilling fluid of the borehole walls, thus enabling a better cement bond to the well. Within this context, this work aims to evaluate the efficiency of mattresses scrubbers, the basis of ionic and nonionic surfactants, on the removal of nonaqueous drilling fluid, based on n-paraffin in oil wells, and the compatibility between the Mattress relations washer / drilling fluid bed scrubber / cement paste mattress washer / cement slurry / drilling fluid and the drilling fluid / cement slurry using laboratory tests rheology, thickening time and compressive strength. Also technique was performed X-ray diffraction (XRD) for a more detailed analysis of these mixtures with hydrated cement paste. In compatibility tests the conditions of temperature and pressure used in the same laboratory procedure simulating the conditions of oil wells, the well is considered the depth of 800 m. The results showed that the compositions of the mattress washer nonionic, KMS obtained a 100% efficient in removing the non-aqueous drilling fluid, and the best formulation showed good results with respect to compliance testing

Avaliação das propriedades físico-químicas de sistemas a base de carboximetilcelulose e poli (N-isopropilacrilamida) em soluções aquosas para aplicação na indústria do petróleo

Sustainable development is a major challenge in the oil industry and has aroused growing interest in research to obtain materials from renewable sources. Carboxymethylcellulose (CMC) is a polysaccharide derived from cellulose and becomes attractive because it is water-soluble, renewable, biodegradable and inexpensive, as well as may be chemically modified to gain new properties. Among the derivatives of carboxymethylcellulose, systems have been developed to induce stimuli-responsive properties and extend the applicability of multiple-responsive materials. Although these new materials have been the subject of study, understanding of their physicochemical properties, such as viscosity, solubility and particle size as a function of pH and temperature, is still very limited. This study describes systems of physical blends and copolymers based on carboxymethylcellulose and poly (N-isopropylacrylamide) (PNIPAM), with different feed percentage compositions of the reaction (25CMC, 50CMC e 75CMC), in aqueous solution. The chemical structure of the polymers was investigated by infrared and CHN elementary analysis. The physical blends were analyzed by rheology and the copolymers by UV-visible spectroscopy, small-angle X-ray scattering (SAXS), dynamic light scattering (DLS) and zeta potential. CMC and copolymer were assessed as scale inhibitors of calcium carbonate (CaCO3) using dynamic tube blocking tests and chemical compatibility tests, as well as scanning electron microscopy (SEM). Thermothickening behavior was observed for the 50 % CMC_50 % PNIPAM and 25 % CMC_75 % PNIPAM physical blends in aqueous solution at concentrations of 6 and 2 g/L, respectively, depending on polymer concentration and composition. For the copolymers, the increase in temperature and amount of PNIPAM favored polymer-polymer interactions through hydrophobic groups, resulting in increased turbidity of polymer solutions. Particle size decreased with the rise in copolymer PNIPAM content as a function of pH (3-12), at 25 °C. Larger amounts of CMC result in a stronger effect of pH on particle size, indicating pH-responsive behavior. Thus, 25CMC was not affected by the change in pH, exhibiting similar behavior to PNIPAM. In addition, the presence of acidic or basic additives influenced particle size, which was smaller in the presence of the additives than in distilled water. The results of zeta potential also showed greater variation for polymers in distilled water than in the presence of acids and bases. The lower critical solution temperature (LCST) of PNIPAM determined by DLS corroborated the value obtained by UV-visible spectroscopy. SAXS data for PNIPAM and 50CMC indicated phase transition when the temperature increased from 32 to 34 °C. A reduction in or absence of electrostatic properties was observed as a function of increased PNIPAM in copolymer composition. Assessment of samples as scale inhibitors showed that CMC performed better than the copolymers. This was attributed to the higher charge density present in CMC. The SEM micrographs confirmed morphological changes in the CaCO3 crystals, demonstrating the scale inhibiting potential of these polymers

Desenvolvimento e produtividade do maracujazeiro-amarelo enxertado em três porta-enxertos

O objetivo deste trabalho foi avaliar o desenvolvimento vegetativo e a produtividade do maracujazeiro-amarelo (Passiflora edulis Sims) enxertado sobre três porta-enxertos em área sem histórico de morte prematura de plantas. O experimento foi conduzido no município de Adamantina-SP, no período de abril de 2006 a junho de 2007, adotando-se o delineamento em blocos ao acaso, em esquema fatorial 3 x 2 + 1 tratamento adicional, com quatro repetições. Os fatores avaliados foram três porta-enxertos: Passiflora edulis, P. alata e P. gibertii, em dois sistemas de enxertia, a hipocotiledonar e a convencional por garfagem tipo fenda cheia, e um tratamento adicional, sem enxertia. Utilizou-se como copa o maracujazeiro-amarelo (Passiflora edulis Sims). Avaliaram-se o diâmetro do caule do porta-enxerto, o diâmetro do caule do enxerto, o comprimento de entrenó, o comprimento dos ramos secundários, o número de ramos terciários, o número de frutos, a massa média de frutos, a produtividade e as fitomassas verde e seca das plantas. Observou-se que as três espécies estudadas podem ser utilizadas como porta-enxertos para o maracujazeiro-amarelo, com diferentes níveis de compatibilidade. P. edulis demonstrou maior compatibilidade como porta-enxerto por apresentar-se superior aos demais na maioria dos parâmetros analisados. Plantas enxertadas sobre P. gibertii apresentaram menor vigor, menor crescimento vegetativo, frutos com menor massa e menor produtividade. A enxertia hipocotiledonar resultou em maior massa média de frutos e maior produtividade no maracujazeiro-amarelo.

Arcabouço geofísico, isostasia e causas do magmatismo cenozóico da província Borborema e de sua margem continental (Nordeste do Brasil)

The Borborema Province (BP) is a geologic domain located in Northeastern Brazil. The BP is limited at the south by the São Francisco craton, at the west by the Parnaíba basin, and both at the north and east by coastal sedimentary basins. Nonetheless the BP surface geology is well known, several key aspects of its evolution are still open, notably: i)its tectonic compartmentalization established after the Brasiliano orogenesis, ii) the architecture of its cretaceous continental margin, iii) the elastic properties of its lithosphere, and iv) the causes of magmatism and uplifting which occurred in the Cenozoic. In this thesis, a regional coverage of geophysical data (elevation, gravity, magnetic, geoid height, and surface wave global tomography) were integrated with surface geologic information aiming to attain a better understanding of the above questions. In the Riacho do Pontal belt and in the western sector of the Sergipano belt, the neoproterozoic suture of the collision of the Sul domain of the BP with the Sanfranciscana plate (SFP) is correlated with an expressive dipolar gravity anomaly. The positive lobule of this anomaly is due to the BP lower continental crust uplifting whilst the negative lobule is due to the supracrustal nappes overthrusting the SFP. In the eastern sector of the Sergipano belt, this dipolar gravity anomaly does not exist. However the suture still can be identified at the southern sector of the Marancó complex arc, alongside of the Porto da Folha shear zone, where the SFP N-S geophysical alignments are truncated. The boundary associated to the collision of the Ceará domain of the BP with the West African craton is also correlated with a dipolar gravity anomaly. The positive lobule of this anomaly coincides with the Sobral-Pedro II shear zone whilst the negative lobule is associated with the Santa Quitéria magmatic arc. Judging by their geophysical signatures, the major BP internal boundaries are: i)the western sector of the Pernambuco shear zone and the eastern continuation of this shear zone as the Congo shear zone, ii) the Patos shear zone, and iii) the Jaguaribe shear zone and its southwestern continuation as the Tatajuba shear zone. These boundaries divide the BP in five tectonic domains in the geophysical criteria: Sul, Transversal, Rio Grande do Norte, Ceará, and Médio Coreaú. The Sul domain is characterized by geophysical signatures associated with the BP and SFP collision. The fact that Congo shear zone is now proposed as part of the Transversal domain boundary implies an important change in the original definition of this domain. The Rio Grande do Norte domain presents a highly magnetized crust resulted from the superposition of precambrian and phanerozoic events. The Ceará domain is divided by the Senador Pompeu shear zone in two subdomains: the eastern one corresponds to the Orós-Jaguaribe belt and the western one to the Ceará-Central subdomain. The latter subdomain exhibits a positive ENE-W SW gravity anomaly which was associated to a crustal discontinuity. This discontinuity would have acted as a rampart against to the N-S Brasiliano orogenic nappes. The Médio Coreaú domain also presents a dipolar gravity anomaly. Its positive lobule is due to granulitic rocks whereas the negative one is caused by supracrustal rocks. The boundary between Médio Coreaú and Ceará domains can be traced below the Parnaíba basin sediments by its geophysical signature. The joint analysis of free air anomalies, free air admittances, and effective elastic thickness estimates (Te) revealed that the Brazilian East and Equatorial continental margins have quite different elastic properties. In the first one 10 km < Te < 20 km whereas in the second one Te ≤ 10 km. The weakness of the Equatorial margin lithosphere was caused by the cenozoic magmatism. The BP continental margin presents segmentations; some of them have inheritance from precambrian structures and domains. The segmentations conform markedly with some sedimentary basin features which are below described from south to north. The limit between Sergipe and Alagoas subbasins coincides with the suture between BP and SFP. Te estimates indicates concordantly that in Sergipe subbasin Te is around 20 km while Alagoas subbasin has Te around 10 km, thus revealing that the lithosphere in the Sergipe subbasin has a greater rigidity than the lithosphere in the Alagoas subbasin. Additionally inside the crust beneath Sergipe subbasin occurs a very dense body (underplating or crustal heritage?) which is not present in the crust beneath Alagoas subbasin. The continental margin of the Pernambuco basin (15 < Te < 25 km) presents a very distinct free air edge effect displaying two anomalies. This fact indicates the existence in the Pernambuco plateau of a relatively thick crust. In the Paraíba basin the free air edge effect is quite uniform, Te ≈ 15 km, and the lower crust is abnormally dense probably due to its alteration by a magmatic underplating in the Cenozoic. The Potiguar basin segmentation in three parts was corroborated by the Te estimates: in the Potiguar rift Te ≅ 5 km, in the Aracati platform Te ≅ 25 km, and in the Touros platform Te ≅ 10 km. The observed weakness of the lithosphere in the Potiguar rift segment is due to the high heat flux while the relatively high strength of the lithosphere in the Touros platform may be due to the existence of an archaean crust. The Ceará basin, in the region of Mundaú and Icaraí subbasins, presents a quite uniform free air edge effect and Te ranges from 10 to 15 km. The analysis of the Bouguer admittance revealed that isostasy in BP can be explained with an isostatic model where combined surface and buried loadings are present. The estimated ratio of the buried loading relative to the surface loading is equal to 15. In addition, the lower crust in BP is abnormally dense. These affirmations are particularly adequate to the northern portion of BP where adherence of the observed data to the isostatic model is quite good. Using the same above described isostatic model to calculate the coherence function, it was obtained that a single Te estimate for the entire BP must be lower than 60 km; in addition, the BP north portion has Te around 20 km. Using the conventional elastic flexural model to isostasy, an inversion of crust thickness was performed. It was identified two regions in BP where the crust is thickened: one below the Borborema plateau (associated to an uplifting in the Cenozoic) and the other one in the Ceará domain beneath the Santa Quitéria magmatic arc (a residue associated to the Brasiliano orogenesis). On the other hand, along the Cariri-Potiguar trend, the crust is thinned due to an aborted rifting in the Cretaceous. Based on the interpretation of free air anomalies, it was inferred the existence of a large magmatism in the oceanic crust surrounding the BP, in contrast with the incipient magmatism in the continent as shown by surface geology. In BP a quite important positive geoid anomaly exists. This anomaly is spatially correlated with the Borborema plateau and the Macaú-Queimadas volcanic lineament. The integrated interpretation of geoid height anomaly data, global shear velocity model, and geologic data allow to propose that and Edge Driven Convection (EDC) may have caused the Cenozoic magmatism. The EDC is an instability that presumably occurs at the boundary between thick stable lithosphere and oceanic thin lithosphere. In the BP lithosphere, the EDC mechanism would have dragged the cold lithospheric mantle into the hot asthenospheric mantle thus causing a positive density contrast that would have generated the main component of the geoid height anomaly. In addition, the compatibility of the gravity data with the isostatic model, where combined surface and buried loadings are present, together with the temporal correlation between the Cenozoic magmatism and the Borborema plateau uplifting allow to propose that this uplifting would have been caused by the buoyancy effect of a crustal root generated by a magmatic underplating in the Cenozoic
