At some point during the evolution of life on Earth, inorganic matter became organic, nonliving matter became living. How ...

We propose a novel modeling framework integrating the dynamic material flow analysis approach with life cycle optimization methodology for sustainable design of energy systems.

Current energy systems are not sustainable therefore new renewable energy sources are introduced. Biomass is emerging as an important renewable alternative energy source. The aim of the article is to ...

Examples of this include adjusting the injection pressure and the mould temperature. II Optimising feedback: quantitative measurements made in the current cycle that can be used to adjust the next ...

Recent progress in the analysis of seismic waves enables us to determine where, and sometimes how, the base of the mantle deforms.

Endothelial cells regulate their cell cycle as blood vessels remodel and transition to quiescence downstream of blood flow–induced mechanotransduction. Laminar blood flow leads to quiescence, but how ...

Physicists have discovered that the motion of molecules in glass or plastic can be reversed in time if you look at it from a special angle.

This can negatively impact cash flow, as the company may need to pay for materials, labor, and other expenses before receiving payment for the finished product. In summary, the efficiency of the ...

The cash conversion cycle (CCC) is the secret weapon to maximizing cash flow and achieving greater profitability for businesses. It measures the time it takes for a business to turn its investments in ...

Gauging the flows A recent assessment of material flows for various resins indicates a need for significant improvement in recovery and end-of-life processes to ensure a truly circular economy.

The authors propose a simulation-based approach to the evaluation of a product's life cycle including recycling and reuse from the viewpoints of not only environmental impact but also the ...
