Feeding spectra and activity of the freshwater crab Trichodactylus kensleyi (Decapoda: Brachyura: Trichodactylidae) at La Plata basin [PDF]

, 2014
Background: In inland water systems, it is important to characterize the trophic links in order to identify the ‘trophic species’ and, from the studies of functional diversity, understand the dynamics of matter and energy in these environments.

Review of Natural Fibers. Part I—Vegetable Fibers

Journal of Natural Fibers, 2012
Natural fibers, which are an important part of human environment, are also valuable raw materials used for textile and non-textile production. Diversity of natural fiber shapes and forms is caused by their occurrence in different climatic zones. The abundance of the fiber sources arouses interest and gives opportunity for more comprehensive studies and,

Effect of hemp on cement hydration: Experimental characterization of the interfacial transition zone

Results in Chemistry, 2022
Hempcrete is low carbon footprint building material, which consists in a mix of a cement and/or lime binder and vegetal particles (shiv). Its high porosity and low density give it good insulation, hygrothermal and acoustic properties.
