Transitional Phenomenon in Metal Cutting

Cutting Edge: A/WySnJ Transitional B Cells

Ferromagnetism in Transitional Metal-Doped MoS2 Monolayer.

Manipulating electronic and magnetic properties of two-dimensional (2D) transitional-metal dichalcogenides (TMDs) MX2 by doping has raised a lot of attention recently. By performing the first-principles calculations, we have investigated the structural, electronic, and magnetic properties of transitional metal (TM)-doped MoS2 at low and high impurity concentrations. Our calculation result indic...

[The transitional phenomenon in contraction of uterine muscle].

Since the discovery of pregnancy reversal by Dale) and Cushny,2) it is widely believed that progesterone plays a cardinal role for the maintenance of pregnancy in mammals by keeping the estrogen-dominated uterus quiescent and hyposensi tive to any given stimulation till term. If so, what is the mode of action of pro gesterone on the uterine muscle? Taking advantage of findings and methods used ...

Modelling nonlinear regenerative effects in metal cutting

This paper deals with the nonlinear models of regenerative chatter on machine tools. The limitations and actual problems of the existing theory are summarized. These cause difficulties in industrial applications, like in the design of optimum technological parameters, adaptive control and/or vibration-suppression strategies. An industrial machine-tool vibration case is analysed experimentally a...

Comparison of Cutting Ceramics with Hard Metal Cutting Tools

Cutting ceramic tools are used especially at high cutting speeds in the machining process. The highly brittle type of structure and the tendency for cleavage (crack formation) are the infavorable properties of these materials, which keep their hardness at high temperatures. The hard metals are produced by sintering of the carbides such as whisker WC, TiC and TaC with the presence of Co as a bin...
