Experimental analysis of additively manufactured thin-walled heat-treated circular tubes with slits using AlSi10Mg alloy by quasi-static axial crushing test by Mohamed A.S.

“…The bulk of the tested tubes exhibited a crushing force efficiency greater than 0.8. Overall, the presence of slits with length 15 mm and width 5 mm resulted in lower and smoother crushing forces than the straight tubes and, therefore, greater crushing force efficiency, validating them as crashworthy structures.…”

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. …”
