In this review, we use rules and predictions on the stoichiometry of nutrient release originating from algal-based aquatic systems to identify the factors that determine the stoichiometry of nutrient ...

Basic electricity is described in many ways. When an electric circuit flows through a conductor, a magnetic field (or "flux") develops around the conductor. The highest flux density occurs when the ...

The basic materials sector is comprised of companies that produce raw materials, such as steel, aluminum, and crude oil. These companies are the backbones of the global economy: without them ...
