In the process of geothermal tailwater reinjection of sandstone, the problem of plugging has been seriously restricting the continuous development of geothermal reinjection for many years, and the problems of plugging are complex and changeable. The plugging in the process of reinjection can be divided into physical plugging, chemical plugging, microbial plugging and gas plugging. Given these four types of blocking, according to the mechanism characteristics of the blocking caused by them, this paper puts forward corresponding blocking prevention measures and solves the current blocking problems by filtering, adding a scale inhibitor, intermittent reinjection, adding chlorine dioxide and regular lifting. In addition, the existing reinjection process and the equipment flow are relatively simple and cannot achieve the goal of efficient reinjection. Therefore, a complete set of reinjection processes is designed to ensure the efficient reinjection of sandstone geothermal tailwater.

Monitoring platelet aggregation is crucial for predicting thrombotic diseases and identifying the risk of bleeding or resistance to antiplatelet drugs. This study developed a microfluidic device to measure platelet activation with high sensitivity. By controlling exposure time through repeated reinjections, the device enables the detection of subtle changes in platelet activity influenced by lifestyle factors, such as alcohol consumption.

Background: Autologous fat injection has been proposed as a potential alternative to traditional rhinoplasty. However, the technique has been criticized for its disappointing retention and the potential complications associated with underfilling.
Objective: To summarize data on patient satisfaction, retention, complications and reinjection to provide a reference for fat injection for rhinoplasty.

Easily accessible through tabletop experiments, paraxial fluids of light are emerging as promising platforms for the simulation and exploration of quantumlike phenomena. In particular, the analogy builds on a formal equivalence between the governing model for a Bose-Einstein condensate under the mean-field approximation and the model of laser propagation inside nonlinear optical media under the paraxial approximation. Yet, the fact that the role of time is played by the propagation distance in the analog system imposes strong bounds on the range of accessible phenomena due to the limited length of the nonlinear medium.
