In this article, we discuss a new proposed concept of economic engineering that seeks to innovate a new model by combining the theories of Karl Marx and Adam Smith, taking into consideration main economic factors to create a sustainable and inclusive economic system that addresses existing challenges and provides a roadmap for future economic growth. Through a brief analysis of the existing gaps between Marxist and Smithian economics, we developed a new economic matrix that leverages the strengths of both theories while also incorporating the latest insights from modern economic research. Our novel approach to economic engineering represents a fresh perspective on the economy and offers practical tool for addressing the most pressing challenges facing society today.

The characterization of rock mass along the tunnel alignment based on physical, geological and geotechnical data of the project area was used in this work. The support systems were recommended for all geotechnical units using RMR and tunneling quality index (Q-system) support chart. The paper also consists in making a two-dimensional numerical study of the stability of the left lateral slope of the Portal of the tunnel with the Slide 6.0 software and inside provisional support with the Phase.2 2D program. The study shows good results of the internal rock mass stability of the tunnel and satisfactory safety factor (FoS) in terms of collapse analyzes of the lateral slope of the tunnel portals.

This discussion explores the possibility of seeking to create a concept and find a principle of prestressed soils.

War is a deformation in the civilization field.

Despite all these subtle sciences and the wide disciplines that have been discovered and developed by man throughout history, we still suffer from wars and the lack of world peace ... Here comes the big question: How can all these sciences not produce world peace? ... Here comes the great answer to this new century for future generations: I think there is incomplete science that we have not yet discovered ... whose role will be to activate the international community and bring about international balance and peace... Through an international equation that could be called the "global peace equation".

Throughout history men have been passionate about the sea and sailing, this allowed not only the discovery of distant horizons but also the establishment of port counters along the coast, serving firstly shelters for stationary vessels and also as a link between sea and land transport.
