Decriptions of the common issues encountered in UHPLC includes viscous heating which involves heating due to friction within the UHPLC column, quality of injector precision wherein partial-looping in the system was observed affecting the accuracy of the UHPLC, and safety issues due to the exposure of operators to high pressure environment.

The article focuses on the study by the University of Applied Sciences' Center for Energy and Environmental Engineering in Giessen, Germany on the performance of small scale anaerobic digesters using agricultural substrates as feedstocks. The study assesses the degradation capacity of the digesters for volatile fatty acids (VFA) and organic dry matter (ODM). Result shows performance issues in digesters due to lack of experience by operators.

The article offers some tips on how to improve the efficiency of filters, regulators, and lubricators (FRLs). It recommends machine operators to use the appropriate size filter, level of filtration, and size of lubricators. It also suggests to consider prepackaged FRLs, consumption sensor, and other engineering tools.

Condition monitoring is the practice of using various sensors and data analysis to assess the operating state of machines and equipment. For example, temperature and vibration data can be collected using a temperature sensor and accelerometer, respectively, to gather data on an overhung fan bearing to assess its condition. Conversely, motor rebuilders could use condition monitoring data to determine if a motor or encoder has a defective bearing or the problem lies elsewhere. [Extracted from the article]
