This article surveys recent and not so recent literature in the field of rotational molding. The mechanisms of heat transfer, sintering and bubble removal are evaluated; as are degradation and dimensional stability. The parameters that affect the surface finish are highlighted and a number of the control systems available to the rotational molding process are mentioned. Improvements in molds and machinery, and the extent to which they reduce cycle times are also described. Finally, the range of materials available to the rotational molding process is examined and recent developments are highlighted. Of particular interest is the rotational molding of liquid polymer systems; which are shown to possess great potential for fulfilling many of rotational molding's surface quality requirements while simultaneously reducing cycle times.

The thermodynamics and weak cosmic censorship conjecture in Reissner-Nordström anti-de Sitter black holes are investigated by the scattering of the scalar field. The first law of thermodynamics in the non-extremal Reissner-Nordström anti-de Sitter black hole is recovered by the scattering. The increase of the horizon radius indicates that the singularity is not naked in this black hole. For the near-extremal and extremal black holes, the validity is tested by the minimum values of the function f at their final states. It is found that both of the near-extremal and extremal black holes can not be overcharged.When ω = qφ, the final state of the extremal black hole is still an extremal black hole. When ω = qφ, it becomes a near-extremal black hole with new mass and charge.

We investigated a giant magnetoresistance (MR) effect of two-dimensional electron gas systems subjected to a periodically modulated magnetic field. It is found that the MR ratio of such a periodically modulated system shows strong dependence on the space between the magnetic potentials. With the increase in the number of periods, the maximal MR ratio tends to be enhanced and the peak of the MR ratio locates at a specific relative Fermi energy for the given space between magnetic potentials. Moreover, the maximal MR ratio of odd-period configurations is always larger than that of even-period configurations.
