This paper has briefly examined Marx's conception of freedom in modern industrial society. Even a rapid comparison indicates Marx says different things at different *** emphasis shifts from,say,an initial view of freedom based on a quasi-Hegelian view of radical equality and even love to freedom beyond the division of labor,then later a very different view of freedom based on a shorter working day,and so on.

In this paper, models of the global system of the Koyna dam have been created using ABAQUS software considering the dam-reservoir-fbundation interaction. Non coupled models and the coupled models were compared regarding the horizontal displacement of the dam crest and the differential settlement of the dam base in clay foundation. Meta models were constructed and uncertainty quantification process was adopted by the support of Sobol's sensitivity in dices considering five un certain parameters by exploiting Box-Behnken experimental method. The non coupled models results determined overestimated predicted stability and damage detection in the dam. The rational effects of the reservoir height were very sensitive in the variation of the horizontal displacement of the dam crest with a small interaction effect with the beta viscous damping coefficient of the clay fbundation. The modulus of elasticity of the clay foundation was the decisive parameter regarding the variation of the differential settlement of the dam base. The XFEM approach has been used for damage detection in relation with both minimum and maximum values of each uncertain parameter. Finally the effects of clay and rock foundations were determined regarding the resistance against the propagation of cracks in the dam, where the rock fbundation was the best.

With the rapid development of the Internet and computational technologies, the exponential growth of digital data is beginning to overwhelm existing storage device capacities, driving an unprecedented demand for new data storage media. DNA, a natural genetic information storage system, has been proposed as a promising alternative[1]. Compared with traditional siliconbased storage, DNA-based storage hasmany advantages—incredible density,
