Evaluation of the Purity of Magnesium Hydroxide Recovered from Saltwork Bitterns
2022
Magnesium has been listed among the 30 critical raw materials by the European Union. In recent years, many green and sustainable alternative Mg2+ sources have been sought to satisfy the EU’s demand and to avoid mineral ore consumption. In this context, saltwork bitterns, the by-products of solar sea salt production, have attracted much attention thanks to their high Mg2+ concentrations (up to 80 g/L) and low Ca2+ and bicarbonate contents (<0.5 g/L). Although investigations on Mg2+ extraction from bitterns in the form of Mg(OH)2(s) have already been performed, product purity has never been properly addressed. Mg(OH)2(s) is a chemical compound of great interest and extensive utility in num…
Evasion of Tax on Interest Income in a Two-Country Model
2001
t We consider a model where agents can invest money at home and abroad. Their total income comprises interest income from these investments and labor income. Tax on interest income can be evaded — at the risk of being detected and fined. We analyze the optimal portfolio and tax evading decisions of agents with different incomes. In a second step, we scrutinize the optimal government policy. Using different instruments government tries to maximize total tax receipts and to prevent flight of capital as far as possible.
Penalties in the Theory of Equilibrium Tax Evasion: Solving King John’s Problem
2010
The authors characterize equilibria of an income reporting game with bounded returns and no commitment where detected tax evaders are charged the maximally feasible amount. Introducing partial commitment to punishment relief eliminates multiplicity of equilibria. The authors identify a unique limit equilibrium where the poorest citizens evade, intermediate citizens are honest, and the richest citizens are indifferent between evading and truth telling. For small tax rates and auditing cost, committing to a discretionary punishment relief scheme increases expected tax revenue.
Bivalve mollusks shells valorisation and recycling: market potentiality and novel building products
2023
Construction is a fundamental driver of the world economy, recognized as a sector that generates a great contribution to the social and economic development. At the same time, it shows an enormous environmental impact through an unstoppable consumption of non-renewable resources, a high energy consumption, and an associated atmospheric emission of pollutant. Consequently, the research and development of novel and green production processes and sustainable building materials is of paramount importance. The sustainability of materials and production processes could be improved by enhancing and reusing wastes from various industrial sectors. In this paper, the fishery sector will be analysed, …

La transvaloración de las perspectivas. Nietzsche y la crítica de la cultura desde el punto de vista del valor
2018
El artículo analiza el estrecho vínculo entre perspectivismo, genealogía y fisiología en la filosofía de Nietzsche. La tesis cardinal es que el punto de vista del valor es más fundamental que el de la verdad. El método genealógico posibilita el estudio de las condiciones de conservación y crecimiento de los puntos de vista y los valo- res, siguiendo el hilo conductor del cuerpo, con el objetivo de crear nuevos resortes de sentido y salir del nihilismo. Se presta especial atención a la tensión entre dogmatismo y relativismo. Final- mente expongo la noción de “cría” (Züchtung), que posibilita un cuestionamiento radical de la cultura y pone de relieve el carácter fisiológico de la moral. The a…
