A consistent interpretation of recent CR nuclei and electron spectra

We try to interpret the recently updated measurement of the cosmic ray electron (CRE) spectrum observed by Fermi-LAT, together with PAMELA data on positron fraction, in a single-component scenario adopting different propagation setups; we find that the model is not adequate to reproduce the two datasets, so the evidence of an extra primary component of electrons and positrons is strengthened. Instead, a double component scenario computed in a Kraichnan-like diffusion setup (which is suggested by B/C and $\bar{p}$ data) gives a satisfactory fit of all exisiting measurements. We confirm that nearby pulsars are good source candidates for the required $e^\pm$ extra-component and we show that the predicted CRE anisotropy in our scenario is compatible with Fermi-LAT recently published constraints.Comment: Accepted for the publication in the proceedings of the ICATPP Conference on Cosmic Rays for Particle and Astroparticle Physics, Villa Olmo (Como), Oct. 201

Theoretical Comparison between a Traditional Anaerobic Digestion and an Innovative One

The paper, after analyzing the technical characteristics of anaerobic digestion traditional plants of zootechnical effluents, identifies those relating to an innovative system, which divides the evolutionary stages of biodegradation of the material in hydrogenesis aerobic, hydrogenesis anaerobic, acidogenesis-acetogenesis and methanogenesis. The theoretical treatment will have to find validation in the pilot plant which will be building and from which it will be possible to determine additional technical, economic, and environmental indications
