In densely inhabited urban areas, deep borehole heat exchangers (DBHE) have been proposed to be integrated with the pump in order utilize geothermal energy for building heating purposes. this work, a comprehensive numerical model was constructed OpenGeoSys (OGS) software applying dual-continuum approach. The verified against analytical solution, as well by comparing flux distribution. A series of modeling scenarios were designed and simulated study perform DBHE system analysis investigate...
Abstract Deep-borehole heat exchangers (DBHE) are generally coaxial pipes installed in deep boreholes and has become an alternative approach to utilize geothermal energy. Since the performance of DBHE system can be affected by several parameters, it is important optimize design parameters for DBHE. In this paper, based on analytical method, we carried out sensitivity analysis including outer pipe diameter, inner flow rate, materials, grout borehole depth during continuous operation 4 months....
Repurposing groundwater-filled mine cavities for thermal energy storage has demonstrated promising potential to buffer the imbalance of supply and demand. Fractured formations are widespread in old mines due previous excavation activities, which dominates performance efficiency (MTES) system. Therefore, understanding mechanisms fluid flow, heat, solute transport fractured reservoirs MTES system is essential its application assessment environmental impact. In this study, a 3D fracture-matrix...

Developing geothermal energy utilization technology is critical for achieving a low-carbon, high-efficiency system, and carbon neutrality objectives. The deep borehole heat exchanger (DBHE) represents viable solution extracting to meet building heating needs, especially in coal mines or oil fields with abundant depleted boreholes. In this study, more comprehensive three-dimensional numerical model was constructed, incorporating segmented design parameters of the DBHE's inner pipe. model's...
Underground mines, once vital industrial hubs, hold immense potential for innovative applications, including Mine Thermal Energy Storage (MTES). MTES repurposes partially and fully flooded mine cavities as reservoirs storing surplus heat or cold, presenting a novel alternative to conventional Aquifer (ATES). While promising, faces challenges such scaling, corrosion, energy loss, interactions between the geological matrix technical infrastructure.To address these challenges, TU Bergakademie...

Introduction Despite the growing number of studies on role gut microbiota in treating gastrointestinal tumors, overall research trends this field remain inadequately characterized. Methods A bibliometric analysis was conducted using publications retrieved from Web Science Core Collection (up to September 30, 2024). Analytical tools including VOSviewer, CiteSpace, and an online platform were employed evaluate hotspots. Results Analysis 1,421 revealed significant geographical disparities...
Symbiotic nodules comprise two classes, indeterminate and determinate, defined by the presence/absence of apical meristem developmental zonation. Why zonation are absent from determinate remains unclear. Here, we define cell types in developing soybean nodules, highlighting undifferentiated infection zones differentiated nitrogen-fixation zones. Auxin governs zone maintenance. GRETCHEN HAGEN 3 (GH3) enzymes deactivate auxin conjugation promote differentiation. gh3 mutants increased cells...
