Methane conversion using a dielectric barrier discharge reactor at atmospheric pressure for hydrogen production

Plasma Science and Technology 2017年第9期19卷 81-90页

In the present paper, we carried out a theoretical study of dielectric barrier discharge（DBD）filled with pure methane gas. The homogeneous discharge model used in this work includes a plasma chemistry unit, an electrical circuit, and the Boltzmann equation. The model was applied to the case of a sinusoidal voltage at a period frequency of 50 kHz and under a gas pressure of 600 Torr. We investigated the temporal variation of electrical and kinetic discharge parameters such as plasma and dielectric voltages, the discharge current density, electric field, deposited power density, and the species concentration. We also checked the physical model validity by comparing its results with experimental work. According to the results discussed herein, the dielectric capacitance is the parameter that has the greatest effect on the methane conversion and H_2/ch_4 ratio. This work enriches the knowledge for the improvement of DBD for ch_4 conversion and hydrogen production.

A REDUCE code for the newman-Janis algorithm is described. This algorithm is intended to include rotation into nonrotating solutions of the Einstein field equations with spherically symmetry or perturbed spherically symmetry and has been successfully applied to many spacetimes. The applicability of the code is restricted to metrics containing potentials of the form 1/r.

Petro-Structural Study of Paragneiss in the SASCA Domain(GbowéSector at Grand-Bereby),Southwestern Cote d’Ivoire

引用

Journal of Geoscience and Environment Protection 2020年第5期8卷 1-16页

作者： Fossou Jean-Luc Hervé Kouadio Mamadou Sangare n’Guessan nestor Houssou Marc Ephrem Allialy Sagbrou chérubin Djro Laboratory of Geology Mineral and Energy Resources(LGRME)Faculty of Earth Science and Mineral ResourcesFélix Houphouet Boigny UniversityAbidjanCote d’Ivoire

The petrographic and structural study of Gbowé (Grand-Béréby) formations located in the SASCA domain (South-West of Côte d’Ivoire) revealed migmatitic paragneisses. For an in-depth understanding of the petrographic, structural and metamorphic characteristics, six (6) thin sections were made from these paragneisses. These gneisses are characterized by paleosomes and neosomes (leucosome and melanosome), consisting of quartz, garnet, plagioclase, biotite, cordierite, sillimanite, myrmekite and microcline. The mineralogical assemblage thus described indicates a retrograde metamorphism (transition from granulitic facies to amphibolitic facies). The structural and microstructural study identified two types of deformation (ductile and brittle). The ductile deformation is characterized by phases D1 (nE-SW flattening) and D2 (nW-SE flattening), materialized by foliations (n140˚, n050˚), folds (asymmetrical folds, similar folds, concentric folds, ptymatic folds) and boudins. Fracture schistosity and fold fracture schistosity are characteristic of the brittle deformation (phase D3). The microstructural study coupled with the metamorphic study shows that the deformations had an impact on the texture of the minerals (recrystallization and mineral reactions). It also allowed giving the paragenesis of phases D1 and D2. The D1 phase is characterized by garnet1, biotite1, quartz1, sillimanite1 and cordierite1 and the D2 phase is characterized by garnet1, quartz2, sillimanite2, biotite2, garnet2 and orthose2. These parageneses thus highlighted bear witness to a polydeformation and polymorphism that affects the study area.

Venopulmonary ECMO Improved Hypoxemia and Supported the Right Ventricle in a Patient with Decompensated Eisenmenger Syndrome

引用

World Journal of Cardiovascular Surgery 2024年第1期14卷 7-19页

作者： Daniel Manzur-Sandoval Gian Manuel Jiménez-Rodríguez Edgar García-Cruz Ramón Espinosa-Soto Erika Yamali Ramirez-Marcano Yessenia Máyory Téllez-López José Luis Elizalde-Silva Gustavo Rojas-Velasco Cardiovascular Critical Care Unit Ignacio Ch&#225vez National Institute of Cardiology Mexico City Mexico Adult Congenital Heart Disease Unit Ignacio Ch&#225vez National Institute of Cardiology Mexico City Mexico Cardiology Department Ignacio Ch&#225vez National Institute of Cardiology Mexico City Mexico

Mech.nical circulatory and/or respiratory assistance with extracorporeal membrane oxygenation (ECMO) has become a standard of care for patients with circulatory (venoarterial) and/or respiratory (venovenous) failure refractory to standard therapies. Adult patients with congenital heart disease are an increasingly recognized and growing population and include various groups, such as undiagnosed cases in childhood and palliated and/or corrected cases, which require subsequent care because of residual lesions, cardiac arrest/insufficiency, and arrhythmias, among other conditions. In addition, these patients are prone to developing pathologies that are typical of adulthood with a generally increased risk of morbidity and mortality because of their low reserves and organic damage associated with the underlying heart disease, which makes them candidates for ECMO. These patients represent an additional challenge in this therapy because malformations and the presence of a shunt can generally affect the usual cannulation methods and hemodynamic and oximetry monitoring. Thus, the configuration decision must be made on a case-by-case basis. Here, we present a cannulation method, venopulmonary artery ECMO, which provides hemodynamic and respiratory support, and may be ideal for patients with shunts and/or right ventricular dysfunction. To our knowledge, this is the first report of this configuration in patients with congenital heart diseases.
