Abstract: Regular dredging works are necessary for the development of coastal regions and the maintenance of shipping channels. However indiscriminate disposal of the dredged soils in open waters can cause severe and irreversible impact on the marine ecosystem. It is therefore desirable to transform the otherwise waste material into reusable soils, though some form of pre-treatment is necessary to improve the material’s strength and stiffness. This paper describes an exploratory work of admixing dredged marine sediments of predominantly silt contents with activated steel slag for improvement of the mechanical properties. By first identifying the optimum activation concentration of NaOH for the steel slag, the solution was next introduced to the soil-slag mixture for uniform blending. Specimens were prepared per dry weight at ratios of clay : steel slag = 3:7, 5:5 and 7:3, then left to cure for up to 4 weeks. At intervals of 3, 7, 14 and 28 days, bender element and unconfined compressive strength

Abstract: This study aimed at investigating the effect of cash and stock dividends taking into consideration the control variables on Tobin’s Q in Jordanian commercial banks listed on Amman Stock Exchange. To achieve this objective, the study depended on financial reports published in stock exchange market for (16) Jordanian commercial banks during the period from 2009 to 2015, and used multiple and stepwise regression to test study hypotheses. The results of the study indicate that there is a significant and positive effect of cash and stock dividends on Tobin’s Q, and this effect in the favor of cash dividends over stock dividends on Tobin’s Q in Jordanian commercial banks.
