Multiple Influences of Paleogeography, Sequence Stratigraphy, and Fold Structure on Coalbed Methane Accumulation in the Lopingian (Late Permian) of Junlian Coalfield, SW China

Junlian coalfield is one of the main targets for coalbed methane (CBM) exploration and development in the southwest China. Based on field geological survey, core observation, gas content statistics, coal maceral composition, vitrinite reflectance ( R O ), proximate analysis and trace element test, lithological types, lithofacies, sedimentary environment, and structural analysis, this research established the sequence stratigraphy frame, revealed the plane distribution characteristics of sedimentary facies, and defined CBM accumulation mode. The results show that six rock types were identified and further subdivided into twenty lithofacies types. Four types of sedimentary systems such as alluvial plains, delta, lagoon-tidal flat, and carbonate platform were summarized according to their combination characteristics. Additionally, 12-14 fourth-order sequences and three third-order sequences CSI, CSII, and CSIII were divided, and a sequence stratigraphic framework of the Lopingian coal-bearing series was established. Among them, the features of third-order sequence CSIII paleogeography from west to east are alluvial plains, deltas, lagoon-tidal flats, and limited carbonate platforms. Thick coal seams are mainly developed in the sedimentary environment of tidal flats, delta plains, and floodplains behind banks. Closely related to coal seam thickness, gas contents of Lopingian coal seams are generally higher than 8 m3/t, except the low level in northwest and partial denudation areas. CBM accumulation is significantly controlled by the fold structure, and the hydraulic plugging effect makes the syncline core favorable for CBM accumulation. Furthermore, favorable geostress conditions enable the secondary anticline to become a favorable area for CBM accumulation when the sealing conditions are better. This research will provide a theoretical guide for the exploration and development of CBM in the study area.

Diversitate identitară în romanul românesc (1933-1947)

Following the 2020 article on identity diversity in the Romanian novel, this study provides both a statistical account and individual examples of fictional representations of characters in the Romanian novel between 1933-1947. With a three-fold structure, our essay focuses at first on gender diversity, analyzing the ratios between female and male authors and female and male protagonists. It then concentrates on religious, ethnic, and national minorities, using both quantitative and qualitative methods of analysis, exploring how they are represented and approached. Without drawing any definitive conclusions, our undertaking provides a blueprint for further research on identity representations in the Romanian novel.

Operaționalizarea experimentului în critica literară românească

This study has a two-fold structure, in its first part exploring various models of experimental literature, proposed by researchers such as Gerald Prince and Warren Motte, as well as theoretical attempts to define and analyze experimental literature in Romania. The second part focuses on the quantitative analysis of keywords related to “the experimental” found in literary histories of Romanian literature authored by E. Lovinescu, G. Călinescu, Nicolae Manolescu, and Mihai Iovănel, as well as The General Dictionary of Romanian Literature and The Chronological Dictionary of the Romanian Novel. By simply searching several pointedly chosen terms in the corpus, a cartography of what is considered to be experimental emerges clearly, alongside its relation to the canon, to the dynamics of literary genres, and to the temporal evolution of Romanian literature.

The Comprehensive Measure of Meaning

Psychological researchers have advanced several instruments to measure meaning. Philosophers have debated the objective versus subjective status of meaning in life and on the global versus individual or personal aspects of meaning. In this chapter, the authors make use of an emerging consensus in the psychology literature concerning a tripartite structure of meaning as cognitive coherence, affective significance, and motivational direction. They enrich this understanding with important philosophical distinctions to distinguish subdomains within this tripartite understanding. The authors use relevant philosophical distinctions to classify existing measurement items into a seven-fold structure intended to more comprehensively assess an individual’s sense of meaning. The proposed measure, with three items in each subdomain drawn from previous scales, constitutes what is put forward as the Comprehensive Measure of Meaning to hopefully enrich the empirical research on the assessment of, and on the causes and effects of, having a sense of meaning.

Object in Object-oriented Ontology by Graham Haman

This article discusses the main provisions of the object-oriented ontology of Graham Harman. The four-fold structure of an object is analyzed in detail as the relationship of sensory qualities, real qualities, a sensory object and a real object, as a result of the interaction of which the fundamental ontological structures of time and space arise. Some problems arising from the basic postulates of the system, such as the lack of interaction between real objects and the indeterminacy of the "ego", are also addressed.

Learning about noticing, by, and through, noticing

Aspects of noticing which are often overlooked are brought to the surface and illustrated by accounting-for three accounts-of specific phenomena, two of which readers are invited to experience for themselves. These are used as a springboard for both illustrating the Discipline of Noticing as a method of sensitising oneself to notice possibilities for action, and reporting insights achieved through its use. This includes augmenting the discourse of Dual Systems Theory to include S1.5 (emotion) and S3 (creative insight) and linking it to a six-fold structure of the human psyche (enaction, affect, cognition, attention, will and witness). The aim is to enrich the discourse in which to account-for incidents as experienced by teachers themselves, and incidents observed by teachers and other researchers. The paper ends by distinguishing between measurement-based research validation, and phenomenologically-based validation which is part of the discipline of noticing.

The Influence of Fold Structure on Heat Accumulation in Hot Dry Rocks

Hot dry rock resources as one of the most promising clean energy in the future, with large reserves, renewable and other advantages, since the 1970 s, many countries all over the world have explored and practiced a lot on the exploration and development of hot dry rock resources, however, few studied the heterogeneity of the rock and the underground geologic structures of hot dry rock resources influence domain enrichment regularity of heat transfer mechanism. Therefore, this article considered the thermal conductivity of rock anisotropy, and set up a horizontal stratum and a fold strata 2D geological model, through numerical simulation with the field rock samples indoor triaxial rock thermal conductivity test results, introducing the thermal conductivity of rock anisotropy index A = K vertical bedding/ K parallel bedding and analyze the underground geologic structures’ influence on heat transfer in the rock. The results show that the anisotropy of rock thermal conductivity has no influence on the heat transfer process in underground rock strata when the rock layer is horizontal, which can be regarded as one-dimensional multilayer wall heat transfer. Fold structure will influence the underground heat transfer direction, so it is not simply seen as a one-dimensional multilayer flat wall heat transfer process in numerical simulation. At the inclined interface of rock strata, "heat flow refraction" usually occurs, which further affects the direction of heat transfer. As a result, heat is concentrated in the syncline of the fold structure in the deep and anticline in the middle and deep layers, while the temperature distribution in the shallow layer is almost unaffected by the structure. The research results of this paper are of great significance to the delineation of the target area and the development and utilization of the hot dry rock resources.
