Numerosi esempi applicativi inclusi nel libro riguardano in particolare sistemi di cogenerazione e trigenerazion

Bottom-up control of sardine and anchovy population cycles in the canary current: insights from an end-to-end model simulation

Sardine and anchovy can exhibit dramatic decadal-scale shifts in abundance in response to climate variability. Sharpe declines of these populations entail particularly serious commercial and ecological consequences in eastern boundary current ecosystems, where they sustain major world fisheries and provide the forage for a broad variety of predators. Understanding the mechanisms and environmental forcing that drive the observed fish variability remains a challenging problem. The modelling study presented here provides an approach that bridges a comprehensive database with an end-to-end modelling framework enabling the investigation of the sources of variability of sardine and anchovy in the Canary Current System. Different biological traits and behaviour prescribed for sardine and anchovy gave rise to different distribution and displacements of the populations, but to a rather synchronous variability in terms of abundance and biomass, in qualitative agreement with historical landing records. Analysis of years with anomalously high increase and decline of the adult population points to food availability (instead of temperature or other environmental drivers) as the main environmental factor determining recruitment for both sardine (via spawning and survival of feeding age-0 individuals) and anchovy (via survival of feeding age-0). Consistent with this, the two species thrive under enhanced upwelling-favourable winds, but only up to some threshold of the wind velocity beyond which larval drift mortality exceeds the positive effect of the extra food supply. Based on the analysis of the simulation, we found that anchovy larvae are particularly vulnerable to enhanced wind-driven advection, and as such do better with more moderate upwelling than sardines.Universidad de Málaga.

The Other War: The Evolution of United States Psychological Warfare in the Vietnam War From 14 May 1965 to 11 September 1966

The creation of the Joint United States Public Affairs Office (JUSPAO) on 14 May 1965 revitalized the psychological warfare (PSYWAR) campaign in Vietnam after decades of post-World War II drawdown and initiated a more targeted and efficient employment of psychological operations (PSYOP) throughout the American war effort. To understand the evolution of Vietnam-era PSYOP, it is imperative to explore the United States military’s implementation of PSYWAR and analyze how it changed throughout the conflict. The challenges the United States faced conducting the “other war” in Vietnam were evident from the start of its involvement in Vietnam, and the PSYWAR effort, overshadowed by the simultaneous conventional war, continued to face obstacles even as the use of PSYOP evolved. Broad investigations of the psychological conflict are prolific, but in-depth analyses of Vietnam-era PSYOP in support of the American war effort, from the creation of JUSPAO to the South Vietnamese Constitutional Assembly elections on 11 September 1966, reveal that it was not static, but rather evolved through a process of adapting to the enemy and the conditions of the war, becoming more focused and effective as the war progressed. Despite the PSYWAR strategy achieving incredible progress in less than two years, leading to the defection or surrender of hundreds of thousands of enemy troops and even the occupation of the Vietnamese countryside to earn the loyalty of the local populace, the Fall of Saigon on 30 April 1975 marked the end of the conflict. More than thirty years later on 16 October 2006, PSYOP became an official branch of the United States Army, and American PSYOP forces at present continue to use capabilities that were first put to use in Vietnam
