NiZn ferrites are the only materials that can be used in microwave applications (100 MHz - 1 GHz range) such as power supply cores, because they have the highest resistivity among the ferrites.

While the FHWA's 2009 guidelines established baseline design principles for BBMSE walls [1], recent advances in computational modelling and material science have fundamentally enhanced the understanding of these structures and improved the mechanistic interpretation of their structural performance.
The results demonstrated that unconnected walls reinforced with highly extensible materials exhibited a well-defined critical slip surface, highlighting the influence of connection type and reinforcement stiffness on failure mechanisms.
The elasto-plastic Mohr–Coulomb model was adopted to simulate the behavior of both the backfill and the foundation materials.
The corresponding material properties of the facings are presented in Table 1.

Introduction
Ultra-fine materials possess excellent mechanical properties such as high strength and high ductility.
Various methods have been developed to obtain such ultra-fine materials.
Many numerical analyses have been conducted by using finite element method (FEM) to investigate the deformation behaviors of materials and to describe the effects of processing parameters such as the die angles (Φ and Ψ) and friction etc.

Waste to Energy (WTE) involves any waste treatment process to convert non-recyclable waste materials into useable energy through a variety of processes, including combustion, gasification, pyrolization, anaerobic digestion, and landfill gas (LFG) recovery.
The reality is, although WTE technologies employing MSW as their feed-in materials are well developed but the disconformity of the MSW composition, the complexity of the treatment facilities, and the pollutant emissions still express considerable issues for these technologies.
The average composition of Malaysian MSW consists of about 45% food, 24% plastic, 7% paper materials, 6% iron, 4% wood, and 3% glass and the remaining percentage belongs to others thus, remarkable amounts of Malaysia MSW is recyclable.
The differences between modern and old incineration plants are significantly considerable, while the previous one’s recovered neither materials nor energy.
