Influence of Fines on the Compressibility of Surface Sands in Kuwait by Al-Abdulmuhsen, Shaikhah A. N.

“…Moreover, with increasing fines, the compressibility increased as demonstrated by the larger values of Cc at all degrees of relative compaction except at 100% and that the coefficient of consolidation Cv decreased with increasing fines, which means that as the fines increase the time required to achieve a certain degree of consolidation will also increase.…”

Towards understanding the effects of climatic and environmental factors on solar PV performance in arid desert regions (Qatar) for various PV technologies by Touati F.

“…However, amorphous PVs prove to be more robust against dust settlement than mono-crystalline PVs and hence are more suitable for implementation in desert climates like Qatar unless cleaning strategies are devised. It was estimated that 100 days of dust accumulation over mono-crystalline PV panels, caused the efficiency to decrease by around 10%. …”

Enhancement of mechanical and corrosion resistance properties of electrodeposited NiP-TiC composite coatings by Fayyaz O.

“…Vickers microhardness and nanoindentation results demonstrate the increase in the hardness with an increasing amount of TiC particles attaining its terminal value (593HV100) at the concentration of 1.5 g L−1. Further increase in the concentration of TiC particles results in a decrease in hardness, which can be ascribed to their accumulation in the Ni–P matrix. …”
