Development of passive margin, due to thermal cooling of the stretch lithosphere, creates a large accommodation space subsequently filled with sediments brought from the emerging continent once the river system is established [1]. This combination of rapid subsidence and sedimentation generates an instable architecture with large shelf progradation on top of early post-rift sediments [5]. Given the typical fine grain lithology of these deposits, in most of the cases they become overpressure and an ideally zone for...

The problem of industrial ventilation has emerged as a result of the serious pollution problems that arise both in the industrial and industrial environments. Before addressing an industrial ventilation study, the question should be raised whether there is no simpler means of reducing or eliminating the causes of pollution or of reducing pollution by modifying the production process or the design and construction of the actual ventilation system. Verification of ventilation facilities has a strong preventive role ...

Preservation at positive temperatures is limited in time. The common technique to reduce metabolism is by reducing the temperature below ambient, using refrigeration or cryogenics. Therefore, these methods are used to preserve biological matter (cells, tissues, organs, vegetables, fruits etc.). Preservation at negative temperatures is possible with limitations in time and imposes also other biotechnological challenges. Long term preservation below freezing temperatures is not successful yet for organs and tissues....
