Natura e architettura nel giardino di Villa Florio-Pignatelli (Palermo, Sicilia).
2003
ABSTRACT.– Amongst the Sicilian historical gardens it is merited to remember the ornamental garden design of Villa Florio- Pignatelli, situated in the western periphery of Palermo. The building, and probably the garden too, are from the second half of the 18. century. This article contains the result of a cognitive study of its history, architecture and vegetal composition, based on field studies in the garden itself, on bibliographical and archival work. In 1838 it was sold by the Duke of Cumia to Vincenzo Florio, who in following conceded it to his son Ignazio. Already at this time, there was a garden with a "flora all’Italiana" behind the Villa, which had circular vials in radial order, …
Un vocabulari pornogràfic francès-català inèdit
2014
Resum: Antoni Bulbena Tosell és autor d’un manuscrit, i inèdit, vocabulari pornogràfic francès-català català-francès, la Flora pornogràfica francesa: suplement al argot francès / Flore pornographique catalane: supplément à l’argot catalan. És una obra d’aproximadament l’any 1921 que, per la seva temàtica, ell mateix reservava per a no publicar-se. Bulbena és autor d’una discutida obra lingüística, entre la qual trobem diferents diccionaris, alguns d’ells entre el català i el francès. El darrer que publicà és el Diccionari de les lléngues francesa & catalana / Dictionnaire catalan-français (1921) que inclou dos apèndixs, un «Vocabulari d’argot francès» i un «Vocabulari d’argot catalan». …
The Lure of Katanga Copper : Tanganyika Concessions Limited and the Anatomy of Mining and Mine Exploration 1899–1906
2016
This article provides a rare opportunity to follow the inception of mining and mine exploration economy in the first years of the European presence in colonial Zambia and Katanga as seen through the eyes of prospectors and mining experts working for the London-based company Tanganyika Concessions Limited. It draws on company records as well as the personal records of the early company employees who worked in North Western Rhodesia and adjoining Katanga until 1906. The most thought-provoking documents include diaries, letters and photographs, which depict the organisation and processes of early mining work, modes of mine exploration, and relations within the first mining communities and betw…
Two new African and Madagascan species of the genus Holochlora (Orthoptera: Tettigoniidae, Phaneropterinae)
2017
Two new species, Holochlora mauritiana and H. ingrischi from the island of Mauritius and Zimbabwe, respectively, are described. Along with a third species, H. biloba Stål, 1874 from Madagascar, they are the sole African representatives of the mostly Oriental genus Holochlora Stål, 1873, including ca. 60 taxa distributed from India to China. Preliminary hypotheses on biogeographical and evolutionary origin of Afro-Madagascan Holochlora species are shortly discussed.

The intestinal 3M (microbiota, metabolism, metabolome) zeitgeist – from fundamentals to future challenges
2021
The role of the intestine in human health and disease has historically been neglected and was mostly attributed to digestive and absorptive functions. In the past two decades, however, discoveries related to human nutrition and intestinal host-microbe reciprocal interaction have established the essential role of intestinal health in the pathogenesis of chronic diseases and the overall wellbeing. That transfer of gut microbiota could be a means of disease phenotype transfer has revolutionized our understanding of chronic disease pathogenesis. This narrative review highlights the major concepts related to intestinal microbiota, metabolism, and metabolome (3M) that have facilitated our fundame…
An extended reconstruction of human gut microbiota metabolism for personalized nutrition
2020
ABSTRACTUnderstanding how diet and gut microbiota interact in the context of human health is a key question in personalized nutrition. Genome-scale metabolic networks and constraint-based modeling approaches are promising to systematically address this complex question. However, when applied to nutritional questions, a major issue in existing reconstructions is the lack of information about degradation pathways of relevant nutrients in the diet that are metabolized by the gut microbiota. Here, we present AGREDA, an extended reconstruction of the human gut microbiota metabolism for personalized nutrition. AGREDA includes the degradation pathways of 231 nutrients present in the human diet and…
TBSSvis: Visual Analytics for Temporal Blind Source Separation
2020
Temporal Blind Source Separation (TBSS) is used to obtain the true underlying processes from noisy temporal multivariate data, such as electrocardiograms. TBSS has similarities to Principal Component Analysis (PCA) as it separates the input data into univariate components and is applicable to suitable datasets from various domains, such as medicine, finance, or civil engineering. Despite TBSS’s broad applicability, the involved tasks are not well supported in current tools, which offer only text-based interactions and single static images. Analysts are limited in analyzing and comparing obtained results, which consist of diverse data such as matrices and sets of time series. Additionally, p…
N-protonated 2-pyridylnickel(II) complexes insertion of isocyanides into the nickel2-pyridyl bond
1987
The reaction of the binuclear complex [NiCl(μ-2-py)(PPh3)]2 (μ-2-py = μ-C5H4N-C2,N) with the phosphines L (L = PPh3, PMePh2, PMe2Ph or PEt3) or dppe (= 1,2-bis(diphenylphosphino)ethane) in the presence of HClO4 yields the N-protonated 2-pyridyl derivatives trans-[NiCl(2-pyH)(L)2]ClO4 or [NiCl(2-pyH)(dppe)] ClO4 (2-pyH = C5H5N-C2) with a square-planar coordination around the nickel(II) center. These products are largely associated through hydrogen bonding between the NH group and the perchlorate anion, both in the solid and in chlorinated solvents. The configuration in solution has been studied by 1H and 31P NMR spectroscopy. In the complex trans-[NiCl(2-pyH)(PMe2Ph)2]ClO4, the planar 2-pyH…
Dinuclear alkoxo-bridged copper(II) coordination polymers: Syntheses, structural and magnetic properties
2010
Abstract The alkoxo-bridged dinuclear copper(II) complexes [Cu2(ap)2(NO2)2] (1), [Cu2(ap)2(C6H5COO)2] (2) and [Cu2(ap)2μ-1,3-C6H4(COO)2(dmso)2]·dmso (3) (ap = 3-aminopropanolato and dmso = dimethyl sulfoxide) have been synthesized via self-assembly from copper(II) perchlorate, 3-aminopropanol as main chelating ligand and nitrite and isophthalate anions as spacers and benzoate anion as auxiliary ligand. Complexes 1 and 3 crystallize as 2D and 1D coordination polymers, respectively, and their structures consist of dinuclear [Cu2(ap)2]2+ units connected with nitrite and isophthalate ligands. The adjacent dinuclear units of 2 and 1D polymers of 3 are further connected by hydrogen bonds resultin…
