L'architettura dei padiglioni dell'alimentazione e della ristorazione nelle esposizioni dell'Oltremare del Secondo Imperialismo

2014

Il periodo compreso fra le rivoluzioni liberali del 1848 e lo scoppio della seconda guerra mondiale nel 1939 (che dà il via al tramonto della cosiddetta “età aurea” del sistema capitalista e della supremazia del “vecchio continente” sul resto del mondo), pur in maniera difforme, è caratterizzato da un nuovo scenario economico e tecnologico della civiltà occidentale che riconosce nelle grandi esposizioni internazionali e nazionali, ma anche in quelle regionali e coloniali, le sedi più idonee per azioni di propaganda commerciale e politica. L’origine del genere delle esposizioni coloniali, che prende il via in sordina e con sensibile ritardo, è puramente mercantilistica e si manifesta inizial…

A Measure of Concurrent Neural Firing Activity Based on Mutual Information

2021

Multiple methods have been developed in an attempt to quantify stimulus-induced neural coordination and to understand internal coordination of neuronal responses by examining the synchronization phenomena in neural discharge patterns. In this work we propose a novel approach to estimate the degree of concomitant firing between two neural units, based on a modified form of mutual information (MI) applied to a two-state representation of the firing activity. The binary profile of each single unit unfolds its discharge activity in time by decomposition into the state of neural quiescence/low activity and state of moderate firing/bursting. Then, the MI computed between the two binary streams is…

Stimulation of the sphenopalatine ganglion in intractable cluster headache: expert consensus on patient selection and standards of care.

2014

Context and overview Chronic cluster headache (CCH) is a debilitating headache disorder with a significant impairment of the patients' lives. Within the past decade, various invasive neuromodulatory approaches have been proposed for the treatment of CCH refractory to standard preventive drug, but only very few randomized controlled studies exist in the field of neuromodulation for the treatment of drug-refractory headaches. Based on the prominent role of the cranial parasympathetic system in acute cluster headache attacks, high-frequency sphenopalatine ganglion (SPG) stimulation has been shown to abort ongoing attacks in some patients in a first small study. As preventive effects of SPG-sti…

The Origin of Isolated Populations of the Mountain Weevil, Liparus glabrirostris—The Flagship Species for Riparian Habitats

2020

AbstractLiparus glabrirostris is one of the largest European weevils, and it has been recently proposed as the flagship species for threatened riparian habitats in the mountains. For effective conservation of its populations (and associated habitats), it is crucial to understand its history, contemporary distribution, genetic diversity and predict changes in the range, including its highly isolated populations on the Baltic coast. Here, we examined numerous populations of L. glabrirostris across almost the entire species range using phylogeography and species niche modeling (SNM) approaches. Analyses of mtDNA and nucDNA markers revealed the existence of 2 major mitochondrial lineages genera…

La culture en campagne : de l'atonie à la mobilisation antifasciste. Politique culturelle et débat public en France lors des élections de 2002

2004

International audience; Cet article part de l'absence de débat sur la politique culturelle au cours de la campagne électorale des élections présidentielles et législatives du printemps 2002. Il montre les ressorts de cette atonie, avant d'expliquer le réflexe anti-fasciste qui marque les semaines qui suivent le premier tour des présidentielles et la présence de Jean-Marie Le Pen au second tour. L'analyse de la défaite du candidat socialiste est aussi un moment de remise en cause du modèle français de politique culturelle. Le débat s'estompe vite et ne débouche pas sur la mise en place d'une politique culturelle 'refondée'.

The Cultivation of Conformity: Towards a General Theory of Internal Secularisation

Nowe dla Niziny Mazowieckiej i rzadkie gatunki ryjkowcowatych (Coleoptera: Curculionidae) z Kampinoskiego Parku Narodowego

2013

New data on the occurrence of 16 weevil species from the Kampinos National Park are presented, of which 7 species are recorded from the Mazovia Lowland for the first time. Among them two, Otiorhynchus repletus BOHEMAN and Larinus sturnus (SCHALLER) figure in the "Polish Red List".

Nemastoma bidentatum (Arachnida: Opiliones: Nemastomatidae): neu für Deutschland und die Tschechische Republik

2007

Nemastoma bidentatum (Arachnida: Opiliones: Nemastomatidae): first records for Germany and the Czech Republic. N. bidentatum Roewer, 1914 was found at two places in Germany: first on the island "Harriersand" in the Weser river (Lower Saxony), second on the banks of the river Elbe in the Elbsandsteingebirge (Saxony). Adjacent to the latter locality an occurrence in the Czech Republic could be located close to the German/Czech border in the floodplain of the river Elbe as well. These records are the first for Germany and the Czech Republic. They enlarge the distribution area of N. bidentatum remarkably in both a northern and a western direction. The two populations show conspicuous difference…

Investigating a simplified method for noninvasive genetic sampling in East African mammals using silica dried scat swabs

2020

Abstract Swabbing scat has proved to be an effective noninvasive method to collect DNA from mammals in the field. Previously, this method has relied on preservative liquids or freezing to preserve the DNA collected on swabs. In this study, we determine the effectiveness of using silica to simply dry the swab in field as an alternative way to prevent DNA degredation. Four species were included in the study; reticulated giraffe, impala, fringe‐eared oryx, and lion. Swabs were taken at multiple time points for giraffe and impala scat samples, with the lion and oryx sampled opportunistically. Mitochondrial DNA was successfully amplified and sequenced from scat swabs from all species; however, e…

Divergent Distribution in Vascular and Avascular Mammalian Retinae Links Neuroglobin to Cellular Respiration

2005

The visual function of the vertebrate retina relies on sufficient supply with oxygen. Neuroglobin is a respiratory protein thought to play an essential role in oxygen homeostasis of neuronal cells. For further understanding of its function, we compared the distribution of neuroglobin and mitochondria in both vascular and avascular mammalian retinae. In the vascular retinae of mouse and rat, oxygen is supplied by the outer choroidal, deep retinal, and inner capillaries. We show that in this type of retina, mitochondria are concentrated in the inner segments of photoreceptor cells, the outer and the inner plexiform layers, and the ganglion cell layer. These are the same regions in which oxyge…
