On the Conceptual History of the Term Lingua Franca
2015
This paper aims to give an outline of the development of the term “Lingua Franca”. Initially the proper name of an extinct pidgin, to “Lingua Franca”, the term has become a common noun, used with regard to language contact phenomena in general – at first specifically for pidgins and trade languages, but now for all vehicular languages. This broader usage is especially prominent in the field of research known as “English as a lingua franca” (ELF). Using ELF as an example, it is shown that the modern usage is partly inconsistent and can be misleading, as it connects a positive feature of the original Lingua Franca, viz linguistic equality, with a language with native speakers like English, wh…
Developing MLS Location-Based Service Pilot System
2002
Development of mobile networks and terminals provides basis for advanced mobile services and applications. One of the new features is support for locating the mobile user by her/his terminal. The Location-Based Services (LBS), utilising this feature, are expected to form an important class of the new services. At the Information Technology Research Institute, University of Jyvaskyla, LBSs have been studied in MultiMeetMobile research project. The project developed an LBS pilot system, called MLS. This paper presents the experiences collected during the development of the LBS pilot and describes the MLS system.
Un contrato de los Hernandos para la capilla de les Febres de la Seo de Xàtiva en 1511
2006
The contract dated 1511 signed by Fernando Llanos and Fernando Yáñez de la Almedina, Castillian painters known as “the Hernandos,” for the termination of an altarpiece in the chapel of the “Virgen de les Febres” is presented here. This chapel was founded in 1497 in the collegiate church of Jàtiva (Valencia) by Francisco de Borja, Bishop of Teano and Cardinal of Cosenza. Based on this document, a series of hypotheses are put forth concerning the trajectory and works of “the Hernandos” following their execution of the doors of the main altarpiece of the Cathedral of Valencia.<br><br>Se presenta el contrato firmado en 1511 por Fernando Llanos y Fernando Yañez de la Almedina, pintor…
Anglicisms in Tourism Language Corpora 2.0
2015
Abstract The world of tourism has evolved in recent times because of the impact of the Internet. Tourism enterprises have expanded their commercial point of view and have found a faster way to reach clients through increased tourism advertising on the Web. Along with this increase in advertising are the opportunities to study the lexicon of tourism. One of the main points in this lexicon is the use of foreign words, especially the use of Anglicisms due to English's status as a universal language in these contexts. In this article, we will study the Anglicisms in Spanish tourism from these points of view: • why these words are used; • in what context they are used; • if we use original forei…
The Impact of Grain Size Composition and Organic Matter Content on Magnetic Susceptibility of Anthropogenically Transformed Bottom Sediments, as Exem…
2017
The article presents the results of an analysis of the surface layer of bottom sediments in the naval harbour in Hel. During field work conducted in June 2013, 54 sediment samples were collected. The aim of the study was to examine magnetic susceptibility of harbour sediment as a parameter determining the degree of anthropopressure. As part of laboratory tests, grain size analysis was performed in order to determine organic matter content and magnetic susceptibility of the sediment. The study also measured the impact of environmental factors on fluctuations in the other studied parameters. The results demonstrate increased dynamics of sedimentary environment in the open part of the naval ha…
Evaluation of historical atmospheric pollution in an industrial area by dendrochemical approaches
2019
International audience; We conducted a dendrochemical study in order to evaluate the exposure of territories and 19 populations to different types of pollutants and to characterise the history of pollution in one of the 20 most intensely industrialised areas of Europe: the industrial port zone of Fos, also heavily 21 urbanised. 22 To perform the study, two tree species have been selected, Pinus halepensis and Populus nigra, on arural plot located roughly 20 km away from the industrial harbor, an urban plot located in the city of Fos-sur-Mer and an industrial plot. Our study indicated that poplar was a more relevant model forthe dendrochemical studies exhibiting a higher bioaccumulation capa…
Blackfly Larvae (Simulium spp.) Can Intensify Methylmercury Biomagnification in Boreal Food Webs
2020
AbstractGlobal pollution of mercury (Hg) threatens ecosystem and human health. We measured total Hg (THg) and monomethylmercury (MMHg) concentrations in filter-feeding blackfly (Simulium spp.) larvae in the inflows and the outflows of six boreal lakes with no Hg point source pollution. THg in the larvae ranged from 0.03 to 0.31 mg kg−1 dw and MMHg between 0.02 and 0.25 mg kg−1 dw. The proportion of MMHg in the larvae was 74 ± 0.16% and ranged from 43 to 98% of THg, the highest proportions being comparable to those typically found in aquatic predatory insects and fish. We compared the larvae MMHg concentrations to river water quality, catchment land-use, and to size-adjusted lake pike THg da…
Distribution of Heavy Metals in Marine Sediments of Palermo Gulf (Sicily, Italy)
2008
Concentrations of Cr, Cu, Hg, Pb and Zn have been measured, by atomic absorption spectrophotometry, in the fine fraction (<63 μm) of surface sediments collected in 30 sites in the Palermo Gulf (Sicily, Italy) in order to assess the levels and the spatial distribution of these elements. Enrichment factors calculated with respect to clean areas have been considered to discriminate between levels due to background or to pollution contributions. The sampling stations, which form a grid inside these areas, are characterized by geographic proximity and by the presence of pollution sources. Ratio matching technique along with hierarchical clustering, minimum spanning tree and principal component a…
Innovative Computational Approach to Harmonic Mitigation for Seven-level Cascaded H-Bridge Inverters
2020
Low frequency modulation strategies are a good solution to increase the energy conversion efficiency in high power applications. The paper is devoted to presents an innovative way to low order harmonics mitigation for seven-level Cascaded H-Bridge Inverters. In particular, this approach is based on the mitigation of selected harmonics without solve non-linear equations for an extended range of the fundamental amplitude. In fact, in real-Time operation to evaluate the control angles the polynomial equations have been identified. Through circuit simulation analysis in MatLab/PLECS environment, the effectiveness of the harmonic mitigation method has been tested and compared with theoretical re…
Novel Computational Method for Harmonic Mitigation for Three-phase Five-level Cascaded H-Bridge Inverter
2018
The efficiency of the system is a very important parameter for high power electrical drives applications,. Moreover, in the system the efficiency of the power converter play a fundamental role and for this reason, the soft switching modulation techniques represent the best choice. This paper presents a novel computational method for harmonic mitigation on the output voltage of a five-level, three-phase Cascaded H-Bridge Inverter without solving non-linear equations. Through this simple approach the Working Areas have been identified in which the harmonics reference have minimum amplitude possible. Moreover, polynomial equations to evaluate the control angels have been found. In this way, th…
