In this study, the performance and the useful life of a mixed ceramic tool with S-type edge microgeometry are evaluated for the case of dry turning of Arts AISI 4140 steel hardened to 55 HRC.The influence of the cutting speed and feed rate of the cutting parameters on the tool failure was investigated.The experiments were designed and analysed usin
The vortex rate sensor is a fluidic gyroscope with no moving parts and can be used in very difficult conditions like radiation, high temperature and noise with minimum cost of manufacturing and maintenance.A vortex rate sensor made of wood has been designed and manufactured to study Bottle Lamp Couple Card theoretically and experimentally its stati
A critical question among the researchers working on fungal lipid biology is whether the use of an enriched growth medium can affect the lipid composition of PRO B12 a cell and, therefore, contribute to the observed phenotypes.One presumption is that enriched medias, such as YPD (yeast extract, peptone and dextrose), are likely to contain lipids, w
An equilibrium chance-constrained multiobjective programming model with birandom parameters is proposed.A type of linear model is converted into its crisp equivalent model.Then a birandom simulation technique is developed to tackle the general birandom objective functions and Arts birandom constraints.By embedding the birandom simulation technique,
Studies on opencast mines have Fat Eighth Bundles indicated that the spontaneous colonization of excavations and sedimentation tanks by vegetation is determined not only by the substratum and the land relief, but also by the hydrological and hydrochemical relations in the exploitation hollow.Sometimes, biological invasions can also disturb the natu
