Stipa ×fallax (Poaceae: Pooideae: Stipeae), a new natural hybrid from Tajikistan, and a new combination in Stipa drobovii
2017
Stipa ×fallax nothosp. nov . (Poaceae), from western Pamir Alai Mts (Tajikistan), is described and illustrated. Field observation, numerical analyses of morphology, and pollen grain viability data show that it originated from hybridization between S. drobovii and S. macroglossa subsp. macroglossa , species representing sections Smirnovia and Stipa , respectively. Stipa ×fallax is morphologically close to S. ×alaica and S. ×hissarica , but is distinguished by its shortly pilose lower part of the awn and densely pubescent leaves. Characters distinguishing S. ×fallax from its parental species as well as similar hybrid taxa in section Smirnovia that also grow in Central Asia are presented. The …
European Union legislation on macroalgae products
2021
AbstractMacroalgae-based products are increasing in demand also in Europe. In the European Union, each category of macroalgae-based products is regulated separately. We discuss EU legislation, including the law on medicinal products, foods including food supplements and food additives, feed and feed additives, cosmetics, packaging materials, fertilizers and biostimulants, as well as biofuels. Product safety and consumer protection are the priorities with any new products. Macroalgae products can be sold as traditional herbal medicines. The novel food regulation applies to macroalgae foods that have not previously been used as food, and organic macroalgae are a specific regulatory category. …
Small pelagic fish in the new millennium: A bottom-up view of global research effort
2021
The present review is an outcome of discussions at the ICES-PICES Symposium on Drivers of Dynamics of Small Pelagic Fish convened in Victoria, B.C., Canada in spring 2017.-- This review is a first contribution of a new international Working Group on Small Pelagic Fish started jointly by ICES (WGSPF) and PICES (WG43) to continue world-wide collaboration to advance knowledge on the drivers of populations of SPF.
Marine alien species in Italy: A contribution to the implementation of descriptor D2 of the marine strategy framework directive
2019
A re-examination of marine alien species or Non Indigenous Species (NIS) reported in Italian Seas, until December 2018, is provided, focusing on establishment success, year of first record, origin, potential invasiveness, and likely pathways, in particular. Furthermore, their distribution is assessed according to the marine subregions outlined by the European Union (EU) Marine Strategy Framework Directive: Adriatic Sea (ADRIA), Ionian Sea and Central Mediterranean Sea (CMED), and Western Mediterranean Sea (WMED). In Italy, 265 NIS have been detected with the highest number of species being recorded in the CMED (154 species) and the WMED (151 species) subregions, followed by the ADRIA (143) …
Konforme Abbildung und Greensche Funktion
1949
Mit Hilfe des Additionstheorems Gl. (I, 31) und mit Hilfe der imaginaren Transformation von Jacobi Gl. (I, 33) folgt fur die durch die Funktion λ = sn (z, k) vermittelte, Abbildung der z-Ebene auf die λ-Ebene $$\lambda = {\lambda _1} + i{\lambda _2} = snz = sn\left( {x + iy} \right) = \frac{{snxcniydniy + sniycnxdnx}}{{1 - {k^2}s{n^2}xs{n^2}iy}}$$ .
Migration process of the PEPPOL network from the AS2 to the AS4 protocol according to the European guidelines
2020
The PEPPOL network (PAN-European Public Procurement Online) is migrating from the AS2 to the AS4 protocol according to the guidelines established by the eDelivery platform of the CEF program (Connecting Europe Facility) of the European Commission. This article describes the bases of this migration process, the current status and the next necessary actions for the year 2020. The main objective is to present the analysis of results on the evolution and impact of the adoption of the AS4 protocol by the PEPPOL Access Points in all Europe until 2019.
AS4 message exchange protocol consolidation through the European CEF eDelivery infrastructure
2020
Since 2014, the European Union has supported the creation of cross-border communication networks based on an AS4 eDelivery solution through the Connecting Europe Facility. This article describes the current status of the uptake of the AS4 message exchange protocol in accordance with both the European infrastructure CEF eDelivery and the European regulation n°910/2014 on electronic identification and trust services for electronic transactions in the internal market. The main objective is to present an analysis of the achieved results from the implementation of the AS4 solution in several European projects carried out during the last 12 years to verify the impact of these projects around Euro…
Life Cycle Energy Consumption and Carbon Dioxide Emissions of Agricultural Residue Feedstock for Bioenergy
2021
The depletion of fossil fuels and climate change concerns are drivers for the development and expansion of bioenergy. Promoting biomass is vital to move civilization toward a low-carbon economy. To meet European Union targets, it is required to increase the use of agricultural residues (including straw) for power generation. Using agricultural residues without accounting for their energy consumed and carbon dioxide emissions distorts the energy and environmental balance, and their analysis is the purpose of this study. In this paper, a life cycle analysis method is applied. The allocation of carbon dioxide emissions and energy inputs in the crop production by allocating between a product (g…
Economic feasibility of stationary electrochemical storages for electric bill management applications: The Italian scenario
2016
Battery energy storage systems (BESSs) are expected to become a fundamental element of the electricity infrastructure, thanks to their ability to decouple generation and demand over time. BESSs can also be used to store electricity during low-price hours, when the demand is low, and to meet the demand during peak hours, thus leading to savings for the consumer. This work focuses on the economic viability of BESS from the point of view of the electricity customer. The analysis refers to a lithium-ion (Li-ion), an advanced lead-acid, a zinc-based, a sodium-sulphur (NaS) and a flow battery. The total investment and replacement costs are estimated in order to calculate the cumulated cash flow, …
