The super-precise theory for machining single crystal SiC substrates with abrasives needs to be improved for its chemical stability, extremely hard and brittle.A Berkovich indenter was used to carry out a systematic static stiffness indentation experiments on single crystal 6H-SiC substrates, and then these substrates were machined by utilizing fix
The objective of the presented research was to create an average image of a harvester operator in Poland and to identify factors influencing the degree of mental workload.We used a survey of environmental assessments of workload.The creation of an electronic Serums survey and the support of a company that indirectly employs operators (State Forests
Network slicing is a key technology to support the Serums concurrent provisioning of heterogeneous Quality of Service (QoS) in the 5th Generation (5G)-beyond and the 6th Generation (6G) networks.However, effective slicing of Radio Access Network (RAN) is very challenging due to the diverse QoS requirements and dynamic conditions in the 6G networks.
Abstract Background The Syndermata (Rotifera+Acanthocephala) is one of the best model systems for studying the evolutionary origins and persistence of different life styles because it contains a series of lineage-specific life histories: Monogononta (cyclic parthenogenetic and free-living), Bdelloidea (entirely parthenogenetic and mostly benthic dw
The objective of this study was the evaluation of the production of base oils for lubricants of biological origin using vegetable and used frying oils as feedstock.The production method was based on a two-stage transesterification process.Initially, fatty acid methyl esters were obtained via methanolysis (first stage), and they were used as feedsto
