Our results demonstrate that PVP for patients with BPH is an effective and safe procedure with satisfactory long-term outcomes. Anticoagulant and antiplatelet drugs did not significantly influence the results, or the complication rates.
The influence of rolling bearing contamination on the level of generated vibrations is ignored in many cases. The influence is clearly visible in the theoretical and experimental works on the mathematical modelling of rolling bearing vibration. The authors of the most recent works in this field use substantial simplifications, often ignoring the presence of solid particles between the rolling bearing mating surfaces. However, bearing in mind the continuous improvement of the rolling bearings production processes, a series of exploratory tests in industrial conditions should be carried out, taking into account the factors affecting the bearing vibrations that are crucial in terms of quality control of the manufactured bearings. The analysis presented in this paper show that the cleanliness of the bearings is a critical factor that determines whether the rolling bearings meet quality requirements.
Article presents the general assumptions and the mechanical design of the new device for measuring the friction torque of rolling bearings, as well as preliminary evaluation of the indications on the basis of which further detailed analyses and corrections of the prototype will be made. The device presented in the manuscript is dedicated to quality control as part of its support for rolling bearing plants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
