Gardens on Canvas and Paper: Cataloguing Botanical Abundance in Late Medici Tuscany

2016

What is the purpose of portraying a branch from a pear tree in bloom and fruit, of listing hundreds of citrus varieties or of dissecting a huge truffle? When Cosimo III (1642–1723), the penultimate grand duke of the Medici dynasty, commissioned artists and botanists alike to create comprehensive visual and textual catalogues of Tuscan flora, aesthetics and curiosity seemed to go hand in hand with a demonstration of knowledge and prosperity. This article deals with the collection of botanical paintings by Bartolomeo Bimbi (1648–1730), housed in the Casino della Topaia close to the city of Florence, and with the mainly handwritten work of the grand ducal botanist Pier Antonio Micheli (1679–17…

Tyramine and phenylethylamine production among lactic acid bacteria isolated from wine.

2007

The ability of wine lactic acid bacteria to produce tyramine and phenylethylamine was investigated by biochemical and genetic methods. An easy and accurate plate medium was developed to detect tyramine-producer strains, and a specific PCR assay that detects the presence of tdc gene was employed. All strains possessing the tdc gene were shown to produce tyramine and phenylethylamine. Wines containing high quantities of tyramine and phenylethylamine were found to contain Lactobacillus brevis or Lactobacillus hilgardii. The main tyramine producer was L. brevis. The ability to produce tyramine was absent or infrequent in the rest of the analysed wine species.

Virtues for the Anthropocene

2015

The paper discusses some difficulties that life in Anthropocene poses to our ethical thinking. It describes the sort of ethical task that individuals find themselves confronting when dealing with the planetary environmental quandaries that characterise the new epoch. It then asks what, given the situation, would count as environmentally virtuous ways of looking at and going about our lives, and how relevant virtues can be developed. It is argued that the practice of gardening is distinctively conducive to that objective. Finally, some garden virtues that will be of special importance in the Anthropocene, but have so far been largely neglected by environmental ethicists, are listed and descr…

Beyond the Vegard's law: solid mixing excess volume and thermodynamic potentials prediction, from end-members

2020

Abstract A method has been developed, herein presented, to model binary solid solutions' volume, enthalpy and Gibbs energy using the energy state functions, E ( V , S ) , of the end-members only. The E ( V , S ) s are expanded around an unknown mixing volume, V Mix , and the fundamental equilibrium equation − ( ∂ E / ∂ V ) S = P is used to determine V Mix . V Mix allows us to model enthalpy, straightforwardly. The same argument holds using Helmholtz energy, F ( V , T ) , in place of E ( V , S ) , and the equilibrium equation becomes − ( ∂ F / ∂ V ) T = P . One can readily determine the Gibbs free energy, too. The method presented remarkably simplifies computing of solid mixings' thermodynam…

El diseño del «verde» en el planeamiento del siglo XIX y en Palermo

2013

[SPA] La relación existente entre hombre y jardín ha evolucionado en el tiempo y en relación al lugar. En Europa, en Italia y sobre todo en Palermo es interesante analizar cómo este vínculo se ha desarrollado, y cómo ha influido la función del jardín dentro de la ciudad, a lo largo de los siglos. En la cultura europea, la noción de tiene una raíz etimológica común derivada del latín de la Edad Media Gardinium. Éste se refería a un lugar cerrado y amurallado, evolución del hortus conclusus romano hasta el gardinus medieval, y testimoniaba la permanencia tipológica de una arquitectura con pórtico perimetral, presente también en el claustro de los monasterios.

Impact of 70 years urban growth associated with heavy metal pollution

2014

Historical trends in trace element deposition were analyzed using herbaria specimens. We determined Al, Fe, Mg, Mn, Ca, Na, P, K, S, As, Cd, Cr, Cu, Ni, Pb and Zn contents in leaves of eight specimens collected in 1941. To assess changes, we collected the same plants from a botanical garden in 2012. The concentrations of major elements showed large species variability. However, temporal trends were predominately detected for heavy metals. The Cd, Ni and Cr contents in the 2012 leaves were 10, 13 and 16 times higher, respectively, than in 1941. Urban activities have substantially raised the levels of these metals in urban atmospheres due to changes in human activities over 70 years of urban …

À l’ombre des épées. Les seigneurs de la guerre, gardiens de la Constitution et pouvoirs régulateurs dans l’imaginaire constitutionnel haïtien

2022

Due to a militarised society between 1804 and 1915, the weight of the warlords was heavy in the foundation and maintenance of the Haitian constitutional order. Their mission as guardians is apparent since the Constitution of 1801, and the military was not content to monopolise the supreme magistracy until the US occupation in 1915. Institutional practice, however, leaves much to be desired. The military Senate was defined by President Jean-Pierre Boyer as the moderating power of the institutions between 1839 and 1842, a short-lived attempt to normalise the institutions in the hands of generals at rest. Unfortunately, the political and social climate accompanying the disintegration of the st…

Mating strategies and resulting patterns in mate guarding crustaceans : an empirical and theoretical approach

2012

Because of strong costs associated with each mating event, females are usually not as available for reproduction as males at any given time. Males are therefore in competition with each other for access to receptive females, hence leading to strong sexual selection. One textbook case of such a mating system occurs in moulting crustaceans where females can only be fertilized during a short period following their moult. This has favoured the evolution male strategies to monopolize females before their period of receptivity. Such a precopulatory mate guarding is widespread among many taxa and represents one of the most striking example of males’ competitive traits favoured by sexual selection.…

A transdisciplinary educational experience at the Botanical Garden around scientific travelers

2019

In the framework of the transdisciplinary educational innovative project “Sciences and Arts” at the University of Valencia, we present here the design and outcome of an activity around the phenomenon of scientific travelers. It consisted in a scientific-literary tour through the Botanical Garden of the University of Valencia, that 100 students from the subjects “Natural Sciences for teachers” and “Literary training for teachers” attended. The activity was designed as a collaborative work in which scientific travelers served as a pretext to address six educational aspects that the students from each subject tackled in two different ways: from a more scientific than literary approach and vice…
