Abstract
Three dimensional (3D) seismic survey was acquired and processed in Bornu-Chad basin, Nigeria with the aim of detecting and attenuating multiples to aid proper imaging of the subsurface. The 25.5km2 volume was processed using SeisUp processing software on a 32-Node Cluster Infrastructure (CI) hardware. Considering the imaging objectives and depth of interest of 1.2s-4.5s, the minimum, middle and maximum offsets were set at 500-2300m, 2500-4300m and 4500-7300m respectively. Since the study area comprised of dry open land and swampy Lake Chad, vibroseis and dynamite sources were used respectively. Charge depth was 0m (surface) for vibroseis and 25m dynamite. The dataset was first pre-conditioned, normalized, regularized before application of demultiple process. The detection and demultiple processes based on multiple characteristics of periodicity and velocity discrimination were applied as the multiples have comparable velocity with the primaries. The near-surface reverberations and short-period multiples were attenuated using predictive deconvolution and radon transform algorithms. High resolution radon was performed on post-migrated common-mid-point (CMP) gathers and stacked with 1kmx1km target line velocities. Internal multiples were detected and attenuated using data-driven methodology of extended internal multiple prediction (XIMP). Multiples detected were short, long period and interbed multiples on all frequencies ranges of 0 – 90Hz but useful seismic frequency range was between 20Hz and 70Hz. The frequencies and amplitudes of the primaries and multiples were very comparable, therefore great care was taken in the attenuation processes. The results of this work has produced better seismic section for interpretation of subsurface geology in the study area.

Published: April 2020

Background: Medicine and Physical Education can work together to solve many health problems. Bodybuilding is a multidisciplinary area whose goals can range from body development to the correction of postural problems and the resolution of various pathologies related to human movement. In the case in analysis, the patient presented (at rest) localized pain (twinges) in the anterior face of the left knee, with an intensity of five (0-10 scale), without phlogistic signs, which worsens when performing the squat, hindering him from leaving the bed without pain. Symptoms were exacerbated when descending stairs. Through anamnesis and directed physical examination, it were considered the possible differential diagnosis of pain in the anterior portion of the knee: Diseases in menisci, anterior and posterior cruciate ligament injuries, diseases of knee collateral ligaments, diseases of knee cartilage, diseases of patellar tendon tendinitis and patellar chondromalacia. After a correct diagnosis of patellofemoral pain syndrome, a conservative treatment was performed using bodybuilding. The results were positive after four months of treatment. From this case, it can be concluded that bodybuilding can be an alternative solution for the conservative treatment of Patellofemoral Pain Syndrome

Published: April 2020

Ribulose 1,5-bisphosphate carboxylase-oxygenase (RuBisCO) is the main enzyme involved in atmospheric carbon dioxide (CO2) fixation in the biosphere. This enzyme catalyses a set of five chemical steps that take place in the same active-site within magnesium (II) coordination sphere. Here, a set of electronic structure benchmark calculations have been carried out on a reaction path proposed by Gready et al. by means of the projector-based embedding approach. Activation and reaction energies for all main steps catalyzed by RuBisCO have been calculated at the MP2, SCS-MP2, CCSD and CCSD(T)/aug-cc-pVDZ and cc-pVDZ levels of theory. The treatment of the magnesium cation with post-HF methods is explored to determine the nature of its involvement in the mechanism. With the high-level ab initio values as a reference, we tested the performance of a set of density functional theory (DFT) exchange-correlation (xc) functionals in reproducing the reaction energetics of RuBisCO carboxylase activity on a set of model fragments. Different DFT xc-functionals show large variation in activation and reaction energies. Activation and reaction energies computed at the B3LYP level are close to the reference SCS-MP2 results for carboxylation, hydration and protonation reactions.However, for the carbon-carbon bond dissociation reaction, B3LYP and other functionals give results that differ significantly from the ab initio reference values. The results show the applicability of the projector-based embedding approach to metalloenzymes. This technique removes the uncertainty associated with the selection of different DFT xc-functionals and so can overcome some of inherent limitations of DFT calculations, complementing and potentially adding to modelling of enzyme reaction mechanisms with DFT methods.

Published: April 2020

We present a quantitative NMR study comparing the metabolic activity in a spheroid and a monolayer of the same number of MCF-7 cells. Both cultures were carried out under hypoxic conditions on microfluidic devices with 2.5 µL sample volume. NMR spectra were obtained by periodically inserting the devices into a dedicated micro-NMR probe. The results demonstrate that quantitative, non-invasive metabolomic monitoring of microfluidic cultures with as few as 1250 individual cells is possible. Metabolite concentrations in the cultures were found to change linearly with time. The consumption rates of D-Glucose and the production rates of L-Lactic acid were approximately 2.5 times larger in the monolayer than in the spheroid. In contrast to the spheroids, monolayers exhibited significant production of L-Alanine and L-Glutamine. Due to its non-invasive nature, metabolic monitoring by NMR can complement destructive fluorescent-based assays that are commonly used for read-out in microfluidic cultures.

Published: April 2020

Este estudo tem por objetivo apresentar uma proposta de mapeamento dos riscos geomorfológicos do município de Caicó, utilizando bases compostas por informações geomorfológicas (unidades geomorfológicas e declividade), cobertura da terra e dados censitários. Para realização do mapeamento geomorfológico procurou-se seguir a metodologia de compartimentação geomorfológica do relevo em táxons, proposta por Ross (1992), permitindo identificar uma unidade morfoestrutural, duas unidades morfoesculturais, uma subunidade morfoescultural e cinco modelados, sendo quatro de denudação e um de acumulação. Com a elaboração do mapa de declividade, constatou-se a predominância de zonas pedimentares, cujo nível de ondulação varia majoritariamente entre plano e suave-ondulado. A partir do mapa de uso e cobertura da terra do município, constatou-se uma hegemonia da vegetação esparsa e do solo exposto nas zonas pedimentares, e a presença de vegetação densa em superfícies elevadas ou em contato com pequenos corpos hídricos. Com a análise dos mapas censitários podemos estabelecer se existe ou não a ocorrência de áreas de risco em ambientes urbanos. Os resultados obtidos mostram que todos os mapas elaborados no presente trabalho, fornecem subsídios ao planejamento e zoneamento dos riscos e ao ordenamento do território do município de Caicó. Geomorphological Risks in the Caicó (RN) Municipality A B S T R A C TThis study aims to present a proposal for mapping geomorphological risks in the municipality of Caicó, using bases composed of geomorphological information (geomorphological units and slope), land cover and census data. For the extraction of geomorphological data, we sought to follow the methodology of geomorphological compartmentation of the relief in taxa, proposed by Ross (1992) and Brasil (2009), with adaptations for the semiarid environment. With regard to social data, the 2010 censo was used. From the elaboration of the geomorphological map, the predominance of pedestrian zones was found, whose level of undulation varies mainly between plane, smooth-wavy to moderately-wavy. Through the land cover map, it was possible to verify a hegemony of sparse vegetation and exposed soil in pedestrian zones, and the presence of dense vegetation on elevated surfaces or in contact with small bodies of water. With the analysis of census maps, in turn, we can establish relationships between physical and human variables, for the determination of socio-environmental vulnerability zones. Therefore, it should be noted that the data presented here will serve as a subsidy for urban and environmental planning in the municipality of Caicó. Keywords: Geomorphological Mapping.

Neste estudo foi realizada uma análise comparativa da ocorrência de raios do tipo nuvem-solo (NS), medidos por sensores em superfície e o total de raios (NS e intra-nuvem - IN), derivados de sensoriamento remoto por satélite, objetivando estabelecer uma proporção dos raios NS entre ambos os Lightning Location System (LLS) para o leste da Amazônia. Foram utilizados dados da STARNET e do banco de dados LRTMS (OTD/LIS). A metodologia de análise consistiu no cálculo da Razão Z, da Proporção de Incidência de Raios NS e da Correlação de Pearson. Adicionalmente também foi realizada uma investigação sobre a relação da quantidade de raios NS em função da altitude do relevo. Os resultados apontaram que a incidência de raios NS tem uma oscilação média mensal de 7,5% a 20,4% do total de raios medidos por sensoriamento remoto e a quantidade varia de acordo com o tipo de superfície, sendo que na região oceânica observou-se baixa incidência de raios NS, nas regiões mais próximas ao litoral observou-se no primeiro semestre os maiores valores da proporção de incidência de raios NS, enquanto que no interior do continente, o máximo de atividade elétrica do tipo nuvem-solo apresenta maiores percentuais durante o segundo semestre. Também foi constatado que o relevo não altera a proporção de incidência dos raios NS, uma vez que não foi encontrada uma relação direta somente com a altura do relevo. Relationship Between Total Lightning and Cloud-To-Ground Lightning in Eastern AmazoniaA B S T R A C TAn analysis of the occurrence of cloud-to-ground (CG) lightning, measured by ground-based sensors, and total lightning (CG and intra-cloud (IC) lightning), detected by satellite remote sensing, was performed in this study to compare the proportion of CG lightning between the two lightning location systems (LLS) in Eastern Amazonia. STARNET and LRTMS (OTD/LIS) data were used. The method of analysis consisted of calculating the Z ratio, the proportion of incidence of CG lightning and the Pearson correlation coefficient. Furthermore, the variation in the number of CG lightning flashes as a function of terrain altitude was also investigated. The results indicated that the mean monthly CG lightning incidence ranges from 7.5% to 20.4% of the total lightning measured by remote sensing and that the number of CG lightning flashes varies according to surface type. More specifically, the oceanic region showed low CG lightning incidence, with the regions closest to the coast having the highest proportion of CG lightning incidence in the first semester; in contrast, the CG electrical activity peaked inland during the second semester. The results also showed that the terrain had no effect on the proportion of CG lightning incidence because no direct relationship with terrain height alone was found.Keywords: Proportion, Z Ratio, Terrain Altitude.
