Rare earth oxides such as La2O3 and Gd2O3 are abundant in waste optical glass. The separation of rare is beneficial to the recycling resources. In this study, oxide particles were separated from using high gradient magnetic separation, influence different fluid media (i.e., water, anhydrous ethanol, their mixture) on results was investigated. By measured zeta potential water/ethanol pH water wi...

Induction is the process by which we reason from the particular to the general; In this paper we use ideas from the theory of abstract machines and recursion theory to study this process. We focus on pure induction in which the conclusions "go beyond the information given" in the premises from which they are derived and on simple induction, which is rather a stark kind of induction that deals w...

Purity in module categories and its different generalizations have been present in the literature since the 1960s. Apart from its special role in module theory, the importance of purity increased during the last two decades through the developments of model theory and the study of locally finitely presented categories (e.g., [2, 6]). In the module theory context, that will be our framework, a p...

These instruments are typically calibrated using saturated is especially common when organisms are recovered at salt solutions at 25°, as listed in Table 3. atypically high rates or in numbers that exceed recommended levels for specific categories of products. Additionally, microbial identification is useful in aseptic processing Table 3. Standard Saturated Salt Solutions Used to Calibrate and ...

While creating an industrial system which has an electric motor, the designers should to be think over not only control method but also motor type to create successful and efficiency system. If created system is an electric vehicle, designers have two powerful candidates as traction motor: Brushless AC (BLAC) or Brushless DC (BLDC) motors. In this study, a comparative performance investigation ...
