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. …”

On the application of arabian gulf water in irrigation: A future possibility by Abu Sharar, Taleb [طالب ابو شرار]

“…Barley can tolerate 12 dS m water salinity without any apparent yeild decrement. Yield would decrease by 5% per each additional increment in water salinity beyond 12 dS m Thus, if Gulf water salinity was treated according to the model of plant response to time weighted salinity, then barley could alternatively be irrigated with fresh/Gulf water in a way that would save a minimum of 16% of the applied water. …”
