Reduction acidity of a crude oil with an alcohol ionic liquid 2-methylimidazole solution

El objetivo de la investigación fue la reducción de la acidez de un crudo colombiano (Número Total de Ácidos -TAN) de 4,9 mg KOH/ g Crudo) utilizando un líquido iónico formado in-situ con solución etanólica de 2 metilimidazol para extraer los compuestos ácidos. Se realizó un diseño de experimentos 2[3] con un punto medio y por triplicado, cuyas variables independientes fueron: la relación crudo: reactivos, la relación entre reactivos (2-metilimidazol: etanol) y el tiempo; y la variable dependiente fue el porcentaje de reducción de la acidez. Las mejores condiciones para la mayor extracción de ácidos fueron: una relación entre crudo: reactivos de (1:0,2 p: p), una relación 2-metilimidazol: Etanol al (20% peso/volumen), y un tiempo de agitación de 3 minutos. El máximo porcentaje de remoción de la acidez fue del 83%. El 2-metilimidazol demostró ser una base orgánica alternativa para la reducción de la mezcla ácida en el petróleo, sustituyendo a las bases inorgánicas comúnmente utilizadas que generan problemas como emulsiones y pérdidas de petróleo. El etanol fue un excelente solvente, debido a que la mezcla ácida fue soluble en él y no se perdió crudo en el proceso.The objective of the investigation was the reduction of the acidity of a Colombian crude (Total Acid Number (TAN) of 4,9 mg KOH/ g crude) utilizing an ionic liquid formed in-situ with ethanolic solution 2 methylimidazole to extract the acid compounds. Experimental designs were realized 2[3] with a point and a half and triplicated whose independent variables were: relationship crude: reactives, in between reactives (2 methylimidazole: Ethanol) and the period; the dependent variable was the percentage of the reduction of acidity. The best conditions for the majority acid extraction were: a relationship between crude: reactive (1: 0,2 w: w), a relation 2-methylimidazole: ethanol at (20% w/v), and an agitation period of 3 minutes. The maximum acidity removal percentage was 83%. The 2-methylimidazole demonstrated to be an alternative organic base for the reduction of the acidity mixture of oil, substituting the inorganic bases commonly utilized that generated problems like emulsions and loss of oil. The ethanol was an excellent solvent due to the acid mixture was soluble in it and there was no loss of oil in the process

Tuoris: A middleware for visualizing dynamic graphics in scalable resolution display environments

In the era of big data, large-scale information visualization has become an important challenge. Scalable resolution display environments (SRDEs) have emerged as a technological solution for building high-resolution display systems by tiling lower resolution screens. These systems bring serious advantages, including lower construction cost and better maintainability compared to other alternatives. However, they require specialized software but also purpose-built content to suit the inherently complex underlying systems. This creates several challenges when designing visualizations for big data, such that can be reused across several SRDEs of varying dimensions. This is not yet a common practice but is becoming increasingly popular among those who engage in collaborative visual analytics in data observatories. In this paper, we define three key requirements for systems suitable for such environments, point out limitations of existing frameworks, and introduce Tuoris, a novel open-source middleware for visualizing dynamic graphics in SRDEs. Tuoris manages the complexity of distributing and synchronizing the information among different components of the system, eliminating the need for purpose-built content. This makes it possible for users to seamlessly port existing graphical content developed using standard web technologies, and simplifies the process of developing advanced, dynamic and interactive web applications for large-scale information visualization. Tuoris is designed to work with Scalable Vector Graphics (SVG), reducing bandwidth consumption and achieving high frame rates in visualizations with dynamic animations. It scales independent of the display wall resolution and contrasts with other frameworks that transmit visual information as blocks of images

White Paper 4: Challenges In Biomedicine & Health

Publicado en Madrid, 231 p. ; 17 cm.A lesson that we have learned from the pandemia caused by coronavirus is that solutions in health require coordinated actions. Beside this and other emerging and re-emerging infectious diseases, millions of Europeans are suffering a plethora of disorders that are currently acquiring epidemic dimensions, including cancer, rare diseases, pain and food allergies, among others. New tools for prevention, diagnosis and treatment need to be urgently designed and implemented using new holistic and multidisciplinary approaches at three different levels (basic research, translational/clinical and public/social levels) and involving researchers, clinicians, industry and all stakeholders in the health system. The CSIC is excellently positioned to lead and coordinate these challenges in Biomedicine and Health.Peer reviewe

Single hadron response measurement and calorimeter jet energy scale uncertainty with the ATLAS detector at the LHC

The uncertainty on the calorimeter energy response to jets of particles is derived for the ATLAS experiment at the Large Hadron Collider (LHC). First, the calorimeter response to single isolated charged hadrons is measured and compared to the Monte Carlo simulation using proton-proton collisions at centre-of-mass energies of sqrt(s) = 900 GeV and 7 TeV collected during 2009 and 2010. Then, using the decay of K_s and Lambda particles, the calorimeter response to specific types of particles (positively and negatively charged pions, protons, and anti-protons) is measured and compared to the Monte Carlo predictions. Finally, the jet energy scale uncertainty is determined by propagating the response uncertainty for single charged and neutral particles to jets. The response uncertainty is 2-5% for central isolated hadrons and 1-3% for the final calorimeter jet energy scale.Comment: 24 pages plus author list (36 pages total), 23 figures, 1 table, submitted to European Physical Journal

Hunt for new phenomena using large jet multiplicities and missing transverse momentum with ATLAS in 4.7 fb−1 of s√=7TeV proton-proton collisions

Results are presented of a search for new particles decaying to large numbers of jets in association with missing transverse momentum, using 4.7 fb−1 of pp collision data at s√=7TeV collected by the ATLAS experiment at the Large Hadron Collider in 2011. The event selection requires missing transverse momentum, no isolated electrons or muons, and from ≥6 to ≥9 jets. No evidence is found for physics beyond the Standard Model. The results are interpreted in the context of a MSUGRA/CMSSM supersymmetric model, where, for large universal scalar mass m 0, gluino masses smaller than 840 GeV are excluded at the 95% confidence level, extending previously published limits. Within a simplified model containing only a gluino octet and a neutralino, gluino masses smaller than 870 GeV are similarly excluded for neutralino masses below 100 GeV

Measurements of Higgs boson production and couplings in diboson final states with the ATLAS detector at the LHC

Measurements are presented of production properties and couplings of the recently discovered Higgs boson using the decays into boson pairs, H →γ γ, H → Z Z∗ →4l and H →W W∗ →lνlν. The results are based on the complete pp collision data sample recorded by the ATLAS experiment at the CERN Large Hadron Collider at centre-of-mass energies of √s = 7 TeV and √s = 8 TeV, corresponding to an integrated luminosity of about 25 fb−1. Evidence for Higgs boson production through vector-boson fusion is reported. Results of combined fits probing Higgs boson couplings to fermions and bosons, as well as anomalous contributions to loop-induced production and decay modes, are presented. All measurements are consistent with expectations for the Standard Model Higgs boson

Standalone vertex finding in the ATLAS muon spectrometer

A dedicated reconstruction algorithm to find decay vertices in the ATLAS muon spectrometer is presented. The algorithm searches the region just upstream of or inside the muon spectrometer volume for multi-particle vertices that originate from the decay of particles with long decay paths. The performance of the algorithm is evaluated using both a sample of simulated Higgs boson events, in which the Higgs boson decays to long-lived neutral particles that in turn decay to bbar b final states, and pp collision data at √s = 7 TeV collected with the ATLAS detector at the LHC during 2011
