Esattamente come una vita trascorsa alla finestra ad osservare i bambini giocare nel parco non basta a conoscere e padroneggiare tutte le regole del gioco, una gioventù passata su quel muretto a secco non era stata, per lei, bastevole ad entrare nei vecchi e pesanti scarponi di quella gente, comprendendone i meccanismi che ne regolavano l'esistenza.

Una storia sulla ricerca e il ritrovamento di coloro che se ne sono 'andati' per sempre. Cosa significa quando qualcuno 'se n'è andato' per sempre? Anche il passerotto deve porsi questa domanda. Vuole scoprire dove potrebbe essere andato il suo amico. Per questo, il passerotto parte alla sua ricerca. Età di lettura: da 6 anni.

Il filo rosso della guida escursionistica interattiva per famiglie è incentrato sulla Pachlerzottl, la figura più famosa nel mondo delle leggende sarentine. Lei conduce attraverso la valle, crea il ponte tra passato, presente e futuro, offre attività emozionanti ed escursioni informative e trasmette in modo autentico la vita e il lavoro nella e con la natura.

This acoustics handbook for mechanical and architectural applications is a translation of the German standard work on the subject. It not only describes the state of art of engineering acoustics but also gives practical help to engineers for solving acoustic problems. It deals with the origin, the transmission and the methods of abatement of air-borne and structure-borne sound of different kinds, from traffic to machinery and flow induced sound.

In response to Executive Order S-3-05, an evaluation of the implications to California of possible climate changes was undertaken using a scenario-based approach. The “Scenarios Project” investigated projected impacts of climate change on six sectors in the California region. The investigation considered the early, middle and later portions of the twenty-first century, guided by a set of IPCC Fourth Assessment global climate model runs forced by higher and lower greenhouse gas emission scenarios. Each of these climate simulations produce substantial impacts in California that would require adaptations from present practices or status. The most severe impacts could be avoided, however, if emissions can be held near the lower end of global greenhouse gas emissions scenarios.Reprinted from Climatic Change, Vol. 109: Supplement 1 (2011)

Suitable for both individual and group learning, Engineering Acoustics focuses on basic concepts and methods to make our environments quieter, both in buildings and in the open air. The author's tutorial style derives from the conviction that understanding is enhanced when the necessity behind the particular teaching approach is made clear. He also combines mathematical derivations and formulas with extensive explanations and examples to deepen comprehension. Fundamental chapters on the physics and perception of sound precede those on noise reduction (elastic isolation) methods. The last chapter deals with microphones and loudspeakers. Moeser includes major discoveries by Lothar Cremer, including the optimum impedance for mufflers and the coincidence effect behind structural acoustic transmission.The appendix gives a short introduction on the use of complex amplitudes in acoustics.
