Omphalocarpoidone, a new lanostane-type furano-spiro-γ-lactone from the wood of Tridesmostemon omphalocarpoides Engl. (Sapotaceae)
2013
Abstract Phytochemical studies of the wood and the stem bark of Tridesmostemon omphalocarpoides Engl. (Sapotaceae) led to the isolation of omphalocarpoidone (1), a new lanostane-type furano-spiro-γ-lactone together with β-amyrin acetate (2), taraxerol (3), spinasterol (4), lichexanthone (5), epi-catechin (6), spinasterol 3-O-β- d -glucopyranoside (7), tormentic acid (8), and 1,2,3,4-tetrahydronorharman-1-one (9). Their structures were established on the basis of extensive NMR studies, mass spectrometry, and by comparison of the data with those previously reported in the literature. The structure of the new secondary metabolite was later confirmed by X-ray crystallography. Except for spinast…
Effects of Gibberellic Acid on Morphogenesis and Cardenolide Accumulation in Juvenile and Adult Digitalis obscura Cultures
1993
Summary Effects of gibberellic acid on morphogenesis and cardenolide accumulation in in vitro cultures of Digitalis obscura are reported. Cultures were established from hypocotyls or leaves of axenic seedlings and shoot tips of mature plants. Irrespective of the kind of explant, gibberellic acid by itself did not induce morphogenesis but modified those morphogenic responses promoted by auxins and/or cytokinins, always inhibited organogenesis and favoured both embryo formation and conversion into plants. Gibberellic acid did not significantly affect cardenolide content of plants regenerated from juvenile or mature D. obscura explants.
Quo Vadis, Orthotrichum pulchellum? A Journey of Epiphytic Moss across the European Continent
2022
Orthotrichum pulchellum is a species of epiphytic moss in which a significant expansion from the oceanic part of Europe to the east of the continent has been observed in the recent two decades. The improvement in air quality in Central and Eastern Europe, but also climate change, probably plays a role in this. This study shows what direction of its spreading we can expect in the future. Ecological niche modeling (ENM) is a widespread method to find out species niches in environmental and geographical space, which allows us to highlight areas that have a higher probability of occurrences of the studied species, based on identifying similar environmental conditions to those already known. We …
La conjonction et les autres mots vides: syntaxe structurale et psychomécanique du langage
2014
International audience; Le présent article offre non seulement un élargissement des notions de mots vides, et plus particulièrement celle de conjonction, mais également une conception plus complexe des parties du discours auxquelles la syntaxe structurale de L. Tesnière réserve l’appellation d’outils grammaticaux. D’une part, les analyses proposées introduisent la distinction entrejonctifs intraphrastiques, pour les éléments qui coordonnent les unités linguistiques moins complexes que la phrase, et jonctifs interphrastiques, pour les éléments qui servent d’introducteurs de l’énoncé et unissent les phrases entières. D’autre part, les opérations de jonction et de translation convergent vers u…
Responsible Investment: Taxes and Paradoxes
2017
Abstract Taxes have become an issue of corporate social responsibility (CSR), but the role of taxation is to some extent an ambiguous and controversial issue in the CSR framework. Similarly, another unclear question is what role investors who are committed to sustainable and responsible investment (SRI) see taxes as having on their environmental, social, and governance (ESG) agenda. Corporate taxes have an inverse relationship with the return of the investors: taxes paid directly affect what is left on the bottom line, reducing the return of investors. However, investors are now more aware of tax-related risks, which can include different forms of reputation risk. Corporate tax planning may…
Recognition as Generative Movement. Axel Honneth between Structure of the Self and Second Nature
2021
Il lavoro affronta tematicamente il paradigma del riconoscimento di Axel Honneth attraverso quattro opere principali — Kampf um Anerkennung, Verdinglichung, Das Recht der Freiheit e Anerkennung. Lo scopo principale è quello di distillare i diversi concetti di riconoscimento messi in campo da Honneth, pur mantenendo l'analisi all'interno dell'orizzonte di matrice francofortese, con le sue necessarie implicazioni antropologiche e filosofico-sociali. A una prima parte storico-filosofica segue un ultimo capitolo in cui i diversi concetti di riconoscimento vengono confrontati con la proposta di Hegel, elaborata nella sezione sulla moralità nella Fenomenologia dello spirito. The work thematically…
Energy consumption analysis of robot based SPIF
2013
Part of: Seliger, Günther (Ed.): Innovative solutions : proceedings / 11th Global Conference on Sustainable Manufacturing, Berlin, Germany, 23rd - 25th September, 2013. - Berlin: Universitätsverlag der TU Berlin, 2013. - ISBN 978-3-7983-2609-5 (online). - http://nbn-resolving.de/urn:nbn:de:kobv:83-opus4-40276. - pp. 131–136. Production processes, as used for discrete part manufacturing, are responsible for a substantial part of the environmental impact of products, but are still poorly documented in terms of environmental impact. A thorough analysis of the causes affecting the environmental impact in metal forming processes is mandatory. The present study presents an energy consumption anal…
Adapting to a Global Health Challenge: Managing Antimicrobial Resistance in the Nordics
2020
This article explores the adaptation of Norway and Sweden to one of the major challenges to global public health, antimicrobial resistance (AMR). Guided by assumptions derived from institutional theory, the article investigates whether, and, if so, how the AMR problem has affected the two Nordic countries’ administrative systems and frameworks for Nordic cooperation. The article builds on selected literature, expert interviews, and public documents. The findings suggest that the international impact on Norway and Sweden’s managerial adaptation to AMR is limited. Instead, adaptation takes place through incremental change within existing structures for disease prevention and control and follo…
Is There a Correlation Between the Ease of Doing Business Index and the Haven Score?
2019
The importance of FDI is increasing in the last period, due to their impact on economic growth and development, creating new jobs, increasing productivity. So, many countries are trying to implement economic, financial and fiscal rules and procedures to attract as many foreign investors as possible. Gaps and mismatches between different tax systems are followed by multinational companies, in the spirit of erosion of the tax base and the existence of a lower tax burden. By analyzing the rankings regarding taxation and doing business published periodically by international bodies, a series of correlations can be identified between the indicators considered in order to make these rankings to d…
Plasticizer extraction of Taxol infusion solution from various infusion devices.
1996
Taxol solution extracts the plasticizer DEHP (di(2-ethylhexyl)phthalate) from polyvinyl chloride (PVC) materials. In order to minimize patient exposure to DEHP, Taxol solutions should be prepared and administered in PVC-free materials. Particulate matter may form in Taxol infusion solution over time, so that in-line filtration with microporous membranes not greater than 0.22 microns is advisable. The purpose of this study was to evaluate the suitability of various administration- and in-line filter-sets for Taxol application. The extent of leached DEHP was determined using a Reversed Phase HPLC assay specific for DEHP. The four tested administration-sets, labeled as PVC-free, were all found…
