Key technologies of efficient extraction of coalbed methane (gas) in Guizhou coal mine area
Published 2025-03-01“…It innovated and explored the following high efficiency extraction technology of “four zones” linked Wells in coal mining areas with Guizhou characteristics: ① By laying multi-functional pumping vertical Wells or small inclination oriented Wells in the goaf, it was the first time in Guizhou to realize efficient extraction and development of pressure relief gas in the overlying coal-covered strata and coal-bed methane in the sweet coal seam below the goaf; ② Taking advantage of the characteristics of spatial and temporal dislocation in the production area, the multi-mode extraction mode of “coalbed methane well + relief well + underground drilling” is adopted for the first coal seam mined in the upper protective layer, which realizes the purpose of the upper and lower vertical combined extraction of coalbed methane (gas) Wells and effectively solves the problem of multi-source gas flooding into coal mining roadway and gas accumulation in the upper corner during coal mining under the condition of coal seam group development in Guizhou; ③ In the preparation area and planning area, combined with the terrain and geological characteristics of the two areas, the horizontal well “well factory” + “two pairs of right and wrong” overlapping well layout mode is adopted to realize the efficient extraction of coal bed methane in the plane in advance and pre-pumping of the sweet coal seam and the pressure relief gas in the overlying coal-laden rock in the subsequent mining process, and at the same time to achieve the goal of “replacing the roadway with Wells”; ④ In view of the development of multi-thin coal seam groups in the study area and the development characteristics of “three zones” in the overlying strata after mining, due to the continuous change of the role of “four zones”, the surface coalbed methane Wells are initially deployed in the production area or preparation area, and the “bridge plug bottom sealing + layer selection perforation” technology is adopted to innovate the “transformation” technology of well structure to achieve the purpose of “multi-purpose in one well”; It also provides new technical ideas and accumulated valuable engineering experience for gas management in coal mine area under the condition of multi-thin coal seam group development in Guizhou.…”

Frontotemporal lobar degeneration changes neuronal beta-frequency dynamics during the mismatch negativity response
Published 2024-01-01“…Across bvFTD and PSP groups, the beta response to deviant stimuli (relative to standard stimuli) correlated with clinical severity, but not with atrophy of the prefrontal source region. These findings confirm the proposed importance of higher-order cortical regions, and their beta-power generators, in sensory change detection and context-updating during oddball paradigms. …”

Creative Design as Research The Application of Practice Base Research in Designing the Logo of Didar Gallery of Isfahan
Published 2025-01-01“…In this research design, the author has used four cognitive fields: "Graphics and Sign Design", "Process Design and Triz's Theory of Creativity" (The four basic pillars of Triz: “Contrast”, “Ideality”, “Function” and “Resources”; The eight principles of Triz: “Consolidation”, “Nesting”, “Prior Action”, “Periodic Action”, “Mediator”, “Replacement of Mechanical Systems”, “Homogeneity” & “Phase Transition”), "Contemporary Art and Galleries" (Applying seven features of Contemporary Art: “innovation and experimentation” in the unconventional design process, “using Multimedia as a new tool” in logo design, “conceptual-critical and questioning approach” which has deconstructive features, “process oriented design”, “Multiplicity of meaning”, “Multidisciplinary approach in sound engineering and image engineering” and “Social action and interactivity” through collaboration with different people for sign design) and "Structuralist & Post-Structuralist Philosophy" (Concepts such as “the metaphysics of presence”, “the priority of speech (parole) over writing (language)”, “endless chain of significations” ,“the trace of meaning”, “the Play of presence and absence”, “deferral of meaning”, “difference”).In designing the final logo of Didar Gallery, the designer paid attention to the histogram of the recorded sound of saying the word Didar, instead of a purely written or visual approach, taking into account selected theoretical principles in the four cognitive fields and while visualizing the sound, he redesigned the letters with deformation in its geometry.As a result, in the final design, the designer has increased the creative and thoughtful aspect of the logo by making changes in the design tools and design approach, and by deepening the design -by finding ideas from philosophical propositions (especially Derrida's deconstruction)- to the extent that the gallery logo, in addition to the status of its functionality can be considered as an artwork.…”

Potential physiological mechanisms behind variation in rainbow trout (Oncorhynchus mykiss) to biosynthesize EPA and DHA when reared on plant oil replacement feeds
Published 2025-04-01“…The omega-3 fatty acids, docosahexaenoic acid (DHA; 22:6n-3) and eicosapentaenoic acid (EPA; 20:5n-3), are of primary concern as they provide significant health benefits such as reducing inflammation and improving heart and health function. However, the DHA; 22:6n-3 and EPA; 20:5n-3 available for aquaculture feeds is primarily provided by fish oil which is already limited in availability and expensive, and dietary lipids are consistently being replaced with oil sourced from plants. …”
