Four electromagnetic properties were measured.
Density and the presence of the porosity will greatly affect the electromagnetic properties of MgCuZn ferrites.
The quality factor is affected by grain size, porosity, chemical composition and the presence of second phase inclusions [4.
Hence, any alteration in grain structure and porosity would affect the loss factor.
High ZnO content is associated with better electromagnetic properties.

Gunasegaram et al. [6] used a five-factor, 2-level, 1/2 fractional factorial designs with 4 centre points to identify critical factors affecting shrinkage porosity in permanent mould casting.
Porosity has an adverse effect not only on the mechanical properties, but also on the surface quality of a cast product [9].
In summary, reducing porosity and fold defects will improve production efficiency, mechanical properties, and marketability of castings.
Experiment Details An Ishikawa cause–effect diagram in Fig. 1 was constructed to summarize the factors affecting the quality of the LFC castings in terms of porosity.

A Review on the Mechanical and Physical Properties of Natural Fiber Composites M.
The performance of natural fiber reinforced composites (NFC) are influenced by various factors.
The performances of NFC can be obtained using various properties such as mechanical, physical and chemical properties of natural fibres.
The results have demonstrated a good performance in terms of mechanical properties.
The increases in the mechanical properties ranged between 30% and 43% for the longitudinal tensile and flexural properties, respectively.

The ANOVA method was used to evaluate the influence of varying factors on the overall quality of welds.
However, the addition of elemental powder produced more equiaxed and refined grains than the cryogenic cooling, but the latter provided a best combination of mechanical properties.
The study has a specific focus on grain refinement and its effects on the mechanical, metallurgical, and electrochemical properties of welds.

This research aims to find a way to protect archeological leather from damage by environmental factors, without losing their archaeological appearance.
The mechanical properties of treated samples were enhanced with reduction in the ΔE values.
In general, polymer used to reinforce artifacts, whether natural or synthetic polymer should play its role in restoration without affecting the structure or the antique appearance.
The mechanical properties were tested for samples to estimate the suitable time for the treatment with SBR solutions.
The deterioration in the mechanical properties by ageing for untreated samples was assessed every three days. it was found that the upmost deterioration of the samples mechanical properties were at 12 days, followed by minor decreases up to 18 days.

Nickel-based super alloy GH4169 has been widely used in aerospace industry because of its good mechanical properties under high temperature.
The results show that geometric parameter of cutting tool is one of the important factors affecting tool life.
The chemical composition and mechanical properties are shown in Table 1 and Table 2.
The effect level of different factors such as cutting condition on VB is obtained through orthogonal experiment.
Based on the range analysis for orthogonal design, Range:, the effect level of cutting factors on tool wear is shown as.

There were used following criteria in order to characterize the quality (usability): corrosion resistance, mechanical properties, physical properties, gloss, roughness, and economical criteria.
In the analyzed case we take into account the following criteria: corrosion resistance, mechanical properties, physical properties, gloss, roughness and economic criterion [1-5].
Procedure and experimental material When analysing influence of many factors on properties of being designed detail we encounter difficulties in their assessment since they are the kind of quantities which are in general incomparable and uncountable with each other.
