Grape Stalks Valorization towards Circular Economy: A Cascade Biorefinery Strategy. [PDF]
A cascade protocol for grape stalks valorization has been proposed, characterized by a multidisciplinary strategy using unconventional techniques and subcritical water as a green solvent, where physical/chemical treatments synergistically interact with biological treatments to obtain added value products from all the biomass components.

Abstract This paper aims to investigate how supporters perceive and react to environmental messages that call for reducing the environmental impact of sporting events. Based on prospect theory, we randomly provided 1423 supporters attending football events in Europe with (1) a negative (perceived loss for supporters), (2) a neutral (no perceived gain ...

Second‐Generation Total Synthesis of the Pigment Aurantricholone
Previously, 6,6‐dimethoxy‐6,7‐dihydrobenzocyclohepten‐5‐ones (“ketoketals”) gained by ring‐closing metatheses (“RCMs”) gave 6‐hydroxybenzocyclohepten‐5‐ones (“benzotropolones”) by hydrolyses with 10 equiv. of hot TsOH. Now, an RCM‐based ketoketal allowed to reach the benzotropolone aurantricholone by total synthesis for the second time and to avoid a ...

Abstract The surface of Mars is enriched in Cl and S which is linked to volcanic activity and degassing. Similarly, elevated Ge and Zn levels in Gale crater sedimentary bedrock indicate a magmatic source for these elements. To constrain the relative effects of Cl and S on the outgassing of these trace metals and chemical characteristics of primary ...

Different natural‐occurring aldehydes and ketones have been selected as substrates for MW‐assisted reductive amination over commercial and homemade Rh supported catalysts. MW combined with Rh catalysts allowed 98.2 % yield in benzylamine from benzaldehyde (80 °C, 10 bar of H2, 1 h) and 43.3 % yield in phenylethylamine from acetophenone (80 °C, 5 bar of

Hipoparatiroidismo e pseudohipoparatiroidismo [PDF]
The principal function of the parathyroid hormone (PTH) is maintenance of calcium plasmatic levels, withdrawing the calcium from bone tissue, reabsorbing it from the glomerular filtrate, and indirectly increasing its intestinal absorption by stimulating ...
