Environmentally friendly amino acids are promising candidates for the application of hydrate-based gas solidification technology and others. The formation kinetics macroscopic morphology methane hydrate in presence l-tryptophan were experimentally studied by adopting an isothermal isochoric method. experimental results showed that could not increase nucleation rates hydrates, but it had better kinetic promotion effects on growth than sodium dodecyl sulfate, minimum concentration required to...

Phase equilibria of carbon dioxide (CO2) hydrate in aqueous solutions N-methyldiethanolamine (MDEA) at four different mass fractions (5, 10, 15, and 25 wt %) the temperature range 274.01 to 281.93 K pressure 1.79 4.34 MPa were experimentally investigated by adopting an isochoric search method. The reliability accuracy our experimental apparatus method examined comparing measured data with published ones. enthalpy CO2 dissociation was calculated Clausius–Clapeyron equation. results showed...

The kinetic inhibition of methane hydrate by polyvinylpyrrolidone (PVP) with two ether synergists was studied in a pilot-scale flow loop. An isothermal (273.15 K) and isobaric (6 MPa) experimental method adopted, the were 2-phenoxyethanol (EPH) butyldiglycol (DGBE). We mainly focused on growth kinetics hydrate, it characterized from consumption gas time. It found that formed bulk solutions when inhibitors present, appearance slurry murky. In contrast, preferred to appear wet wall loop liquid...

The influence of carboxymethylcellulose sodium (CMC-Na) on the formation kinetics carbon dioxide (CO2) hydrate was investigated by adopting an isothermal and isochoric method. mass transfer characteristics CO2 in solution CMC-Na were also investigated. Pure water polyvinylpyrrolidone (PVP) different molecular weights used for comparison. Several parameters, such as concentration additives, stirring condition, temperature, experimental results showed that all additives had almost no...

The political concerns underlying Mo Yan's creative work come to the fore in his latest novel, Frogs (Wa), which gives reader an unusual perspective on complex relations between fiction and politics. This novel harshly criticises a state whose coercive population control policies are responsible for some murderous consequences. denunciation is also aimed at economic ultraliberalism that complicit with totalitarian inheritance destruction of human dignity through alienation commercialisation...

The Songliao Basin is a large Mesozoic–Cenozoic continental basin with multiple sedimentary cycles. It has experienced the influence of multidirectional and different structural stresses in peripheral belt, resulting complex geological structure. clastic deposits at depression Quantou Formation shallow part basin, including Fuyu oil layer Yangdachengzi layer, are primary exploration development target. structure faults dominant factors controlling hydrocarbon accumulation upper member...

From Soul Mountain to One Man's Bible, Gao Xingjian's fiction is committed a labour of transgressive remembering: excavating minority heritages eclipsed by the dominant culture, protecting individual memory from established historiography, and sounding dark areas personal memory, less indulge in "repentance" than examine identity. The writing thanks fictionalisation, thus comes resemble an exorcism that makes it possible defy prohibitions casting out external internal demons imposing...

Carbonate sediments are susceptible to many factors, such as paleostructure, diagenesis, and strong microbial alteration; such, their sedimentary architecture still calls for further research. In this study, the reef shoal bodies in XVm XVp layers of Middle–Upper Jurassic Karlov-Oxfordian S gas field were used object, reef-shoal facies was studied. Based on idea “vertical grading horizontal boundary”, interface characteristics 6th 4th levels study area summarized, four ways determine...

The growth kinetics and macroscopic morphology evolution of CO2 hydrate promoted by L-Methionine (L-Met) in NaCl aqueous solutions a wide range mass fractions were investigated. 0.05 wt% was the threshold fraction L-Met to have prominent promotion effects. addition could suppress its performance, while it be regained increasing 1.0 wt%. Further deteriorated performance. It dramatically decreased increased NaCl. Porous feature wall-climbing phenomena obvious presence suppressed tangential...

To facilitate the efficient exploration and development of coalbed methane Longtan Formation in Guxu coal mining area, Sichuan, it is essential to evaluate reservoir characteristics main production layers. In this study, scanning electron microscopy, low-temperature liquid nitrogen adsorption experiments, high-pressure mercury pressure isothermal experiments were conducted investigate favorable reservoirs. The results indicate that seams are medium-to-high ash content anthracite with a...

The work of Mo Yan, renowned Chinese literary author is based on a new kind humanism and representation society in which mankind closely linked to the animal world, this proximity even what makes it human. Some Yan's outstanding works they aim depict are highlighted.

Les théories postcoloniales introduites en Chine au début des années 90 donnent lieu à réinterprétations qui conduisent, entre autres, la naissance d’une théorie « nativiste ». Dans une logique antagoniste qu’on ne saurait attribuer critique postcoloniale, le discours » oppose sinité l’hégémonie culturelle occidentale, révélant un nationalisme essentialiste dissimule mal tentation d’un Orient-Extrême sinocentrique, désamorcée par les revendications intérieures espace pluriel et multipolaire.

La francophonie chinoise, en l’espace de deux décennies, accède à une visibilité accrue grâce son succès médiatique et sa reconnaissance institutionnelle. Elle appelle des investigations sur passé quelque peu occulté par l’histoire. Tcheng Ki-tong (Chen Jitong 1852-1907), diplomate lettré la fin d Dynastie Qing, est ce titre figure emblématique : il illustre ses écrits production diverse rhétorique ambiguë qui oscille entre mythification Chine utopie universaliste exclusive rapports force....

L’engouement auquel on assiste actuellement en Chine pour les études dites «sinologie à l’étranger» ou d’outre-mer», telle que celle-ci est pratiquée l’étranger, nécessite un état des lieux, qui permettra d’observer champ disciplinaire constitution. Le développement de ce domaine émergent n’est pas sans susciter interrogations, portent sur sa légitimité, problématisée par connexion avec savoir nature orientaliste, traité «sinologiste». Les débats révèlent l’ambivalence et tensions règnent...

This collaborative work gathers fourteen articles written by Chinese academics and/or young researchers spread throughout China, the United States, Hong Kong, Macao, England and Australia. As fruit of a “global” collaboration, it projects an image subject at hand. These cultural studies cover areas as varied cinema, tourism, literary criticism, media, advertising, internet. A diversity themes complements this interdisciplinary approach, involving politics, economy, in...

La propagande que la Chine met en œuvre vue de légitimer sa volonté puissance s’avère d’une efficience à fois coercitive et démagogique. Contrairement des tentations compromission constatées jusqu’en Occident, écrivains artistes chinois entendent désenchanter les grands récits nationaux sans cesse renouvelés, mobilisant le pouvoir critique l’imagination, transgressive démystificatrice. Une contre-fiction politique se formule avec inspirations géographiques diverses, profilant dès lors un...

RÉSUMÉ L’oralité dialectale qui a investi récemment la production romanesque en Chine réactualise les débats sur rapports entre création littéraire et communauté linguistique. La présente étude pour visée de réexaminer tensions permanentes le champ aspirant à l’autonomie normativité linguistique dictée par impératifs politiques, idéologiques ou économiques l’État-nation. On cherchera montrer comment écrivains se réapproprient actuellement langue vernaculaire préserver leur subjectivité...
