The spontaneous combustion of residual coal in the gob seriously threatens safety mining. Injecting CO 2 into not only prevents from but also realizes storage mined areas. Injection flux and burial depth port are crucial for -preventing fire mine gobs. In this study, distribution oxidation zone Tanyaoping was field-measured, kinetic model built by adiabatic test. Then, a 3-D mathematical constr...

The technical feasibility of geothermal power production will be demonstrated in the geothermal research wells Groß Schönebeck using a borehole doublet. This task includes safeguarding the thermal fluid cycle and the optimisation of energy conversion technology at the surface. In order to complete the Enhanced Geothermal System, three massive hydraulic stimulations were performed injecting a to...

This experiment investigated the effects of different doses of Bacillus subtilis spore as a probiotic on the immune response, intestinal morphology and ileal dry matter digestibility in broiler chicks exposed to stress induced by corticosterone (CORT). Two hundred and eighty-eight one-day-old Ross 308 male broiler chicks were randomly assigned to six treatments in a <e...

This paper presents the development and field-scale demonstration of a cementitious grout that enables detection in subsurface via addition magnetite . Through strategic use injection borehole an array monitoring boreholes for conducting pre- post-injection magnetic surveys, combined with geologically-based model simulating field anomaly, this technology can locate volume within subsurface. A s...

Climate change is one of the major global concerns. Emission of anthropogenic greenhouse gases is the main cause of climate change. One way of reducing the emissions is the application of carbon capture and storage (CCS) in geological formations. In this study, feasibility of CCS was studied in an Iranian gas production area located in the northern Persian Gulf coast in the south of country. Th...

We apply morphological image processing for quality inspection of microfluidic chips. Based on a comparison of measured topographies with design data, we provide a coherent solution to four central tasks in the quality assessment of injection moulded polymer devices: determination of channel depth, identification of burrs, calculation of transcription accuracy, and detection of defective region...

Background In patients with ischemic cardiomyopathy, radiofrequency ablation for ventricular arrhythmias can have limited efficacy because of the mismatch between lesion depth and substrate thickness, and because radiofrequency-induced edema surrounding the lesion is reversible resulting in only temporary conduction block. We hypothesized that transcatheter needle injection under real-time magn...

We present a phase locking scheme that enables the demonstration of a practical dual pump degenerate phase sensitive amplifier for 10 Gbit/s non-return to zero amplitude shift keying signals. The scheme makes use of cascaded Mach Zehnder modulators for creating the pump frequencies as well as of injection locking for extracting the signal carrier and synchronizing the local lasers. An in depth ...
