Paoline et.al. [8] and Indira et.al. [9] claimed that algae pigments have great commercial value as natural colorants in nutraceutical, cosmetics and pharmaceutical industry as well as their health benefits.
On the other hand, Lee et al. [3], Chandini et al. [4] and Nagai and Yukimoto [10] reported that seaweeds also have a bulk of other bioactive compounds such as fatty acids, polysaccharides and phytosterols which possess several beneficial effects including antioxidant, anticoagulant, antitumor and anti-cancerous properties.

Samples were prepared by uniaxial and isostatic pressing and sintering was carried out in a graphite resistance furnace at 1650°C under argon atmosphere and holding time of thirty minutes. 2.2 Nanocomposites For alumina-niobium carbide powders synthesis was used a mixture of the reactants Al, Nb2O5 and C (carbon black), 0.8 mols of alumina (AKP-30 of Sumitomo - Japan) as diluents.
Nb2O5+ 3.3 Al + 2C + 0.8Al2O3 ®2 NbC+ 2.5 Al2O3 The reactive milling was performed in a SPEX 8000 shaker/mill apparatus with hardened steel vial and balls (10mm in diameter) and charge ratio of 4:1.

In addition, the addition of RE to Mg-Al-based alloys restricts the crystallization of Mg17Al12 phase due to the preferential utilization of aluminium atoms to form Al-RE compounds, the chance of creep-induced precipitation of Mg17Al12 compound that deteriorates creep resistance of Mg-Al based alloys is greatly reduced [1,3].

The first successful trial of RUM process as an ultrasonic milling was carried out by Pei et al. [5] in 1994.
Hu, et al. [6] studied the RUM process with different rotational speeds (1000 up to 3000 rpm) and observed no significant effect of varying speeds on the MRR.
The different cutting depth (10-50 mm) and different feed rate (100-500 mm/min) have also been studied by Lauwers et al. [8].

Model A for TiO2/water nanofluid and Model C for CuO/water nanofluid, and two other experimental models based on the correlation of Pak and Cho [41] for TiO2/water nanofluid (Model B) and Lee et al. [42] with Nguyen et al. [43] for CuO/water nanofluid (Model D).
Same experimental and numerical results were reported by Ben Mansour et al. [47, 48].
These results are consistent with those Izadi et al [33].

Smaga et al [9] found that feed rate is the most important factor which affects the surface roughness of the hole as well as fatigue life.
Lincoln et al conducted experiments in steel using HSS tool to drill the hole at flooded, MQL & dry lubrication levels which proved lubrication affects the hole quality [10].
