  1. The Deceiving ELF? Can Englsh fulfil the role of a Lingua Franca?

    Richard Chapman

    2016-01-01

    Full Text Available Abstract – The debate which surrounds the role of English as a lingua franca has been lively and extensive over the last twenty years or so. Numerous conferences and specific publications in the field testify to the interest and importance that the question of the development of a possible international functional language has stimulated. The present article aims to critically reassess the claims made for ELF and, at the same time, highlight the profound significance of the issues the debate has raised. Discussion of ELF has touched upon the perception of linguistic diversity, (inaccuracy and variation, intelligibility and the potential functions of an international language. Other topics of profound importance that are part of the debate relate to the role of any language in creating and maintaining identity, enabling social mobility and empowering its users. Some criticisms of ELF proposals have been easily rebutted, but this paper aims to underline the serious linguistic and socio-linguistic aspects of the debate in order to emphasize the need for a theoretical underpinning to our understanding of how language can operate in the global environment. Clarification of what we can and cannot know about language change and behavior will also contribute to ideas as to future research in ELF but will also bring us to the conclusion that predictions of the future development of ELF are of little purpose beyond the curiosity value they may possess.

    Mortensen, Janus

    2013-01-01

    This article discusses how English used as a lingua franca (ELF) can be defined as an object of study. It offers a critical appraisal of a high-profile definition of ELF (the VOICE/Seidlhofer definition), and argues that definitions of this kind, whether purposely or not, in effect invite...... approach to the conceptualization of ELF where ELF is defined in straightforward functional terms as the use of English in a lingua franca language scenario. This definition underscores the complexity and breadth of ELF as an object of study, and highlights that researchers in the field of ELF studies need...

  5. English as a lingua franca in higher education

    Björkman, Beyza

    2011-01-01

    The last decade has brought a number of changes for higher education in continental Europe and elsewhere, a major one being the increasing use of English as a lingua franca (ELF) as the medium of instruction. With this change, EAP is faced with a new group of learners who will need to use...... it predominantly in ELF settings to communicate with speakers from other first language backgrounds. This overview paper first discusses the changes that have taken place in the field of EAP in terms of student body, followed by an outline of the main findings of research carried out on ELF. These changes...... and the results of recent ELF research have important implications for EAP instruction and testing. It is argued here that EAP needs to be modified accordingly to cater for the needs of this group. These revolve around the two major issues: norms and standards for spoken English and target use.

  8. The use of English as a lingua franca in translation

    J. A. Foley

    2016-01-01

    Full Text Available In translation, not only two languages but two cultures come into contact which means that translators must consider who wrote the text, when, why, for whom and who is now reading it and for what purpose. In the wake of rapid technological advances and the need to spread information quickly and efficiently, translation has grown in importance in the globalized world. So has its reliance on English in its role as a global lingua franca. English is often being used for ‘interculturalizing’ native languages but it is also true that English texts are written by speakers who use English as a lingua franca (ELF with the additional consequence of local languages being incorporated into the texts. This is the linguistic hybridity used in constructing a wider view of the world. However, the prime aim of any lingua franca communication is mutual intelligibility. Saussure wrote about the contrasting principles of provincialism (ésprit de clocher and what he termed intercourse: the need for broader communication. We can see Saussure’s principles as two imperatives: the cooperative and territorial imperatives. That is to say that language change is brought about by the ‘cooperative imperative’ as we need to continually modify our language in order to communicate with other people. At the same time, there is the ‘territorial imperative’ to secure and protect our own space and sustain our separate social and individual identity. In this study, the translation of linguistic units can only be understood when considered together with the cultural contexts in which they arise, and in which they are used. Blogging in Singapore and the Philippines is part of the ‘cooperative and territorial imperatives’ where the use of English as a lingua franca is intertwined with translanguaging.

  15. English as a lingua franca used at international meetings

    Barančicová Jana

    2015-09-01

    Full Text Available The paper deals with the use of English as a lingua franca. It concentrates on the environment of international meetings where English is used as a lingua franca. The aim of the research conducted through a survey of members of a NATO working group is to find out how native and non-native speakers feel about English used as a lingua franca during international meetings and how these two groups of speakers see each other in multinational interaction from the point of view of linguistics. The sections dealing with non-native speakers concentrate on the level of knowledge of English and on how native speakers cope with the English used during the meetings. The sections dealing with the views of English native speakers should establish the approach they take towards mistakes made by non-native speakers, whether native speakers should adjust the way they speak at international meetings and how they generally view the fact that their mother tongue is used all around the world.

  16. Repertori retorici e negoziazione culturale nei racconti di vita di rifugiati: Lingua Franca e implicazioni ideologiche

    Paola Catenaccio

    2016-01-01

    Full Text Available Abstract – This chapter analyses the storytelling performance of an asylum seeker speaking in English for an international audience and recorded on a video released by the United Nations High Commissioner for Refugees. The primary purpose of the study is to investigate the rhetorical structuring of the narrative in an ethnopoetic perspective (Hymes 2003, and to identify the presence (or, even more significantly, marked absence of dialogic signs of intercultural negotiation deployed in the process of conveying to a culturally diverse audience a highly culturally situated story embedded in a personal narrative of displacement. At the same time, the study also intends to contribute to the current debate on English as a Lingua Franca (ELF by addressing the issue of the inherently situated nature of ELF, and of the political and ideological implications of an ELF approach to intercultural communication in both asymmetric and (programmatically symmetric power situations. The video selected for the analysis was retrieved from the UNHCR Youtube channel and is part of a series called Storytelling: through the eyes of Refugees designed to make refugees’ stories known to the wide public and to legitimise refugees as a category of people endowed with agentivity and self-determination, and with the power of contributing to the discursive construction of their own role and status. Because of their global outreach, these videos qualify as instances of ELF usage in a broad international context and are eminently suited to the investigation and discussion of ELF approaches to conventionally asymmetric institutional communication.

  18. English as a Lingua Franca: Applied Linguistics, Marxism, and Post-Marxist theory

    John Robert Schmitz

    2017-03-01

    Full Text Available ABSTRACT This paper is motived by a reading of “English as a Lingua Franca: An Immanent Critique” (O’REGAN, 2014, who claims that ELF researchers place their work at the forefront of debates with regard to what function and form English should play in the lives of its numerous speakers worldwide. O’Regan questions the use of an epistemology based on a positivist and objectivist paradigm, connected to a postmodernist and poststructuralist ‘sensibility’. To attempt a fair analysis of O’Regan’s critique of ELF, I consider it essential to examine Marxist theory in the light of the analyses of Sim’s (2000 Post-Marxism and of the work published by Laclau and Mouffe (1985. My reading leads me to claim that traditional Marxist thinking is compromised by its association with authoritarian and totalitarian stances, as opposed to Post-Marxist views of pluralism, libertarianism, and openness to the cultural climate of postmodernism. Based on the disillusions of post-Marxist thinkers, I conclude that the views of classical Marxism are not applicable to ‘English as a Lingua Franca’

    Full Text Available The function of English as a lingua franca for communication needs rethinking in the teaching of English as a foreign language classroom as a consequence of globalisation. The present contribution is an empirical study carried out in an Italian university environment which aims to show how teachers should take on board awareness raising activities in the recognition of other varieties of English which, albeit not exploited as benchmarks for language testing and certification, must nevertheless boast a relevant place in the global scenario. This can be achieved in practical terms by interrogating an expressly made corpus of Chinese English news texts and carrying out simple concordance activities.

  10. Dealing with Communicative Problems in English as a Lingua Franca | Traiter les problèmes communicatifs en anglais considéré comme lingua franca

    Agnieszka Nowicka

    2008-01-01

    Full Text Available De nos jours, l’anglais est l’une des langues les plus utilisées dans la communication internationale. Les locuteurs qui recourent à l’anglais en tant que lingua franca maîtrisent cette langue de façon inégale. Cependant, dans ce type d’échanges les locuteurs ne sont pas confrontés uniquement à des problèmes d’origine linguistique. Notre but, dans le présent article, est de réfléchir, tout d’abord, à la question de comment les différences socio-culturelles, au niveau des styles d’interaction, peuvent influencer la communication. Ensuite, on se focalisera sur les différentes façons dont les locuteurs réagissent aux problèmes de cette nature lorsqu’ils apparaissent dans l’interaction et, finalement, on démontrera comment ces problèmes sont négociés par les locuteurs. Nous recourrons à l’analyse conversationnelle afin d’analyser des extraits d’interactions en anglais qui serviront d’illustration.

  17. Italian as lingua franca, the law of connected vessels and the improvement of the results into the multilingual class. About a teaching experience

    Alessia Terrusi

    2017-01-01

    Full Text Available This contribution takes cue from a teaching experience of Italian L2 to A1-level immigrant students within the SPRAR project in Lucca from November 2015 to May 2016. During lessons, the class has been enriched with students from different places in the world and who talked very different languages. Multilingualism had only one underlying theme: the Italian language used during the lessons. It was the same Italian language which they got accustomed to by living in Italy since about a year. The experience started from the hard fact that the only common knowledge was this basic-level Italian language. So a new strategy was tested: to create couples or small groups made up with students linguistically different (like anglophones with francophones. They were forced to use Italian language and let other students understand through their previous knowledges due to the daily contact with the Italian reality. This brought very positive results such as the creation of discussions about the activities, the mutual correction of mistakes, the increase of communication skills through alternative strategies (like mime or drawing. Despite the different individual and initial levels, Italian language as lingua franca let them understand Italian language more efficiently.L’italiano come lingua franca, il principio dei vasi comunicanti e il miglioramento dei risultati nella classe plurilingue.

  18. Chinese English in as lingua franca in global business setting: A case study of ongoing emails of a foreign company in China

    Wang Wenpu

    2016-01-01

    Full Text Available With the process of globalization, English has been increasingly become the lingua franca for people speaking different languages to communicate with each other, among whom the number of non-native speakers of English far outnumbers those native speakers in traditional sense. Against this background, the principle of taking the rules of native English speakers as the norms is undergoing challenges. The non-native speakers are claiming the ownership and rights of norm-providing to the English language (Crystal, 2003. In business setting, this is especially true (Charles, 2007. This paper intends to explore the use of Chinese English as lingua franca in business setting. Taking a foreign enterprise based in China as the case, this paper investigates over 400 ongoing business e-mails written in English by its Chinese employees, including the management and other staff. Four most salient patterns of Chinese English structures are identified, i.e., punctuations, absence of inflectional markers in number and tense, serial verb construction, and zero articles, which are then analyzed cultural, linguistic and social-linguistic perspectives. The effectiveness of such language patterns are proved according to the principle of “understandability” proposed by Kachru and Nelson (2006 from both intra-cultural and inter-cultural aspects. Based on the afore-said analysis, this paper concludes that Chinese English, during the process of language contact, has become a legitimate English variation, and has been providing new norms for the other countries to follow. It is suggested that business English users in China need to use their Chinese English with a confident stance, while business partners from other countries need to get familiar with this English variation in order for them to communicate effectively with their Chinese partners.

    Full Text Available Teacher education represents an essential step to raise awareness of the sociolinguistic changes brought about by the current pluralization of English and by its lingua franca role. Within the pre-service teacher education programs run at the Department of Foreign Languages and Literatures, University of Verona, Italy, part of the English language course focused on issues related to World Englishes (WE and English as a lingua franca (ELF, aiming at fostering awareness of and active reflection upon their pedagogical implications. After taking into consideration recent developments in WE- and ELF-aware teacher education, we will report on findings from a research study involving trainee teachers attending the aforementioned courses for English in academic years 2012-13 to 2014-15. The main aim of the study has been to investigate whether, how and to what extent trainee teachers’ pedagogical knowledge and reasoning about a WE and ELF-informed perspective in teaching practices may undergo a change after attending these courses. Drawing upon different sets of data (questionnaires, reflections in e-learning discussion forums, interviews and final reports, the trainees’ increased awareness of and readiness to include a WE- and ELF-informed didactic approach after attending the course will be discussed, together with implications for foreign language teacher education.

    Patricia Pullin

    2011-08-01

    Full Text Available English as a lingua franca (ELF has been described as “… the fastest-growing and at the same time the least recognised function of English in the world.” (Mauranen 2009. As a shared language used between speakers who do not have the same lingua cultural backgrounds, English has been the global language of business for some time (Charles 2008 and is increasingly used in academia, not only as the lingua franca of research, but also for teaching and administrative work. As a field of research, ELF focuses on language use in context, notably showing how flexible users of ELF are in negotiating meaning and achieving understanding, despite differences in cultural and linguistic backgrounds (Firth 1996, 2008. Yet, using English as a lingua franca can present challenges, and the research findings have implications not only for users of English in a range of contexts, but also for teachers and learners of English. The focus of this article is on the effect of change with regard to English on curriculum development and syllabus design at the University of Zurich and Federal Institute of Technology (ETH Zurich Language Center. Drawing on Richards (2001, curriculum development refers here to an overall process of educational planning and implementation, comprising needs analysis, situation analysis, setting of aims and learning outcomes, course design, delivery and assessment. These elements are seen as a “network of interacting systems.” (Richards 2001:41. Syllabus design, on the other hand, deals with the specific content covered in a given course.

    Full Text Available This article aims to explore whether well-attested findings in the fields of World Englishes (WE and of English as a lingua franca (ELF have determined a shift in perspective in the overall approach to English language teaching (ELT, and how far this shift has permeated teaching materials and coursebooks. The research study was carried out in Italy, a country where ELT coursebooks have often played a relevant role in introducing innovations in language teaching methodology. The research design included a corpus of ten coursebooks that have been published and adopted in Italian secondary schools in the last 6 years. The coursebooks were evaluated in terms of the presence or absence of references to WE and/or ELF, of awareness-raising activities, of the promotion of using English outside the school environment and of the use of effective English communication and intercultural strategies among nonnative speakers. Findings show that there have been no significant changes in the inclusion of WE- and ELForiented materials and related tasks, apart from the area of promotion of cultural and intercultural awareness.

    2013-10-01

    Full Text Available Hitherto, most research into cohesion has concentrated on texts (usually written only in standard Native Speaker English – e.g. Halliday and Hasan (1976. By contrast, following on the work in anaphora of such scholars as Reinhart (1983 and Cornish (1999, Christiansen (2011 describes cohesion as an interac­tive process focusing on the link between text cohesion and discourse coherence. Such a consideration of cohesion from the perspective of discourse (i.e. the process of which text is the product -- Widdowson 1984, p. 100 is especially relevant within a lingua franca context as the issue of different variations of ELF and inter-cultural concerns (Guido 2008 add extra dimensions to the complex multi-code interaction.

  6. ELF in English language teaching: Researching attitudes of Serbian academic community

    2016-01-01

    Full Text Available The aim of the empirical part of the research was to explore the attitude of the Serbian academic community towards the English language used as lingua franca (ELF, i.e. neutral variety of the English language. The results might be a starting point in considering whether to include ELF in the language policy and, consequently, into English curricula in Serbia. The research included members of Serbian academic community, students of different departments, and English language teachers in the state owned and privately owned universities in Belgrade, Novi Sad and Nis. After examining their attitudes towards key postulates of ELF the conclusions are that it is necessary to start discussions about the concepts of the variety and to reassess current deeply rooted ideas about the English language from the perspective of modern linguistic trends. The need for a more liberal approach to the variety is not generated only in the needs of the market, i.e. those people to whom English is a practical means of international communication, but also the need to adjust ELT (English Language Teaching to modern linguistic tendencies and the European Council recommendations.

    Full Text Available Abstract – English has been increasingly adopted as the Lingua Franca (ELF by people with different L1s (cf. Crystal 2003; McArthur 2003; Seidlhofer 2004 and diverse lingua-cultural backgrounds (Cogo et al. 2011. Previous research into its syntax (Mauranen and Ranta 2009 has undoubtedly shed light on some recurrent features of intercultural communication in immigration and asylum contexts (e.g. negation, question formulation, if-clauses, but little attention has been paid to the correlation between personal pronouns, semantic verb types and tense within the communicative process and, more specifically, the report of any traumatic event (Tuval-Mashiach et al. 2004 to which immigrants have been exposed over time and which constitutes what is generally referred to as Post-Traumatic Stress Disorder (PTSD; Friedman et al. 2007; Liotti and Farina 2011.

The site, Becoming Minnesotan, collects excerpts from oral interviews conducted between 1967 and 2011 with recent immigrants to Minnesota usually fleeing civil war and strife, and their American-born children. By adopting the quantitative research methodology typical of corpus linguistics (Biber et al. 1999; Meyer 2002; Sinclair 1991, we searched for and extracted all the instances of semantic verbs types as well as personal pronouns and mapped their frequencies by means of Wordsmith Tools 6 (Scott 2012.

  18. Developing Intercultural Communicative Competence in ELF Communication

    Lili Cavalheiro

    2015-06-01

    Full Text Available The traditional notion of English as a foreign language solely for communicating with native speakers can no longer be applied in a world that is constantly changing, hence paving the way for an alternative use of the language known as English as a lingua franca. As a result, instead of focusing only on grammatical correctness, research into language pedagogy has also come to recognize the importance of exploring bottom-up learning processes, and developing intercultural communicative competence (ICC and more communicative-based methods. Nowadays, it is essential to acquire the knowledge, skills, attitudes and critical cultural awareness necessary to communicate successfully. To show the importance of integrating ICC in language pedagogy, a recording from the Vienna-Oxford International Corpus of English is analysed here to demonstrate the significance of developing critical awareness as well as several communicative strategies, so that language learners can afterwards have the necessary ICC to interact in today’s multi-lingual/cultural society.

  19. NAS investigates ELF

    Gledhill, M.

    1997-01-01

    A report published in October 1996 by a committee appointed by the US National Research Council has concluded that 'no conclusive and consistent evidence shows that exposures to residential electric and magnetic fields produce cancer, adverse neurobehavioural effects, or reproductive and developmental effects'. However, the committee also noted that 'an association between residential wiring configurations ... and childhood leukemia persists in multiple studies, although the causative factor responsible for that statistical association has not been identified.' The committee was set up in 1991 at the request of the US Congress, and asked to concentrate on extremely low frequency (ELF) electric and magnetic field exposures found in residential settings. The expertise of its 16 members covered the wide range of disciplines necessary to evaluate the extensive research literature. Research into the possible health effects of ELF magnetic fields has been driven largely by epidemiology, and a comprehensive meta-analysis of 11 childhood leukemia studies forms a key part of the report. These studies have used several metrics to define 'exposure' of the study subjects to ELF fields. The meta-analysis combined the studies in a number of ways to evaluate their consistency and sensitivity to individual study results. (author). 1 ref

  8. Transcript profiling of Elf5+/- mammary glands during pregnancy identifies novel targets of Elf5.

    Renee L Rogers

    Full Text Available BACKGROUND: Elf5, an epithelial specific Ets transcription factor, plays a crucial role in the pregnancy-associated development of the mouse mammary gland. Elf5(-/- embryos do not survive, however the Elf5(+/- mammary gland displays a severe pregnancy-associated developmental defect. While it is known that Elf5 is crucial for correct mammary development and lactation, the molecular mechanisms employed by Elf5 to exert its effects on the mammary gland are largely unknown. PRINCIPAL FINDINGS: Transcript profiling was used to investigate the transcriptional changes that occur as a result of Elf5 haploinsufficiency in the Elf5(+/- mouse model. We show that the development of the mouse Elf5(+/- mammary gland is delayed at a transcriptional and morphological level, due to the delayed increase in Elf5 protein in these glands. We also identify a number of potential Elf5 target genes, including Mucin 4, whose expression, is directly regulated by the binding of Elf5 to an Ets binding site within its promoter. CONCLUSION: We identify novel transcriptional targets of Elf5 and show that Muc4 is a direct target of Elf5, further elucidating the mechanisms through which Elf5 regulates proliferation and differentiation in the mammary gland.

    Paola Luigia Cattoretti

    2010-09-01

    Full Text Available Acquisire una nuova lingua non è mai un percorso semplice. Il cammino che il migrante deve compiere per apprendere l'italiano è costellato di difficoltà e di ostacoli dovuti ad emozioni contrastanti, al  trauma causato dall'esperienza della migrazione, dalle condizioni, spesso di forte disagio, di lavoro, del contesto in cui si trova a svolgere una nuova vita, dalla qualità o meno dell'accoglienza, dalle possibilità reali, sul piano sociale, di integrazione. Lo scopo di questo articolo consiste nel mettere in evidenza il passaggio complesso dalla lingua madre alla cosiddetta lingua adottiva, mostrando come in taluni casi l'italiano, imparato nei corsi per stranieri o a scuola dai più giovani sia divenuto uno straordinario strumento grazie al quale poter evocare il paese d'origine e raccontare il proprio vissuto. Lo scrivere in una lingua diversa permette al migrante non solo di narrare fatti ed esperienze che magari preferirebbe non raccontare nella lingua madre, ma di diventare costruttore di cultura.   Learning a new language is never a simple task. The new-comer's experience of learning Italian is marked by difficulties and obstacles caused by contrasting emotions, the trauma from the experience of migration, the often difficult work conditions, the living conditions in the host country, the presence or absence of feeling welcomed, and the real chances for social integration. This paper aims at highlighting the complex passage from the mother tongue to the so-called adopted language, showing how in some cases learning Italian, thanks to courses for foreigners or as children at school, has become a wonderful tool for evoking the home country and telling about life there. Writing in another language allows migrants not only to recount facts and experiences that they might prefer not to tell in their own language, but it is a cultural building block as well.

    2004-06-01

    Biologists are increasingly recognising that computational modelling is crucial for making sense of the vast quantities of complex experimental data that are now being collected. The systems biology field needs agreed-upon information standards if models are to be shared, evaluated and developed cooperatively. Over the last four years, our team has been developing the Systems Biology Markup Language (SBML) in collaboration with an international community of modellers and software developers. SBML has become a de facto standard format for representing formal, quantitative and qualitative models at the level of biochemical reactions and regulatory networks. In this article, we summarise the current and upcoming versions of SBML and our efforts at developing software infrastructure for supporting and broadening its use. We also provide a brief overview of the many SBML-compatible software tools available today.

A group of undergraduate students was asked to produce an intralingual translation for the subtitles of the video Capsized in Lampedusa – Fortress Italia, which deals with the situation in Lampedusa after a boat capsized in October 2013. The original video – available on YouTube – is subtitled into English for Vice News and, in a ‘role play’ exercise (Rosnow 1990, students were commissioned to adopt a type of English that could be directed at a wider international audience also including non-native English speakers. The contrastive analysis of the original and reformulated versions is designed to enquire into the influence and actualisation of the commissioner’s requests in the lexical, structural and functional features of target texts. The extent will also be explored, to which the type of English adopted in the alternative subtitles can be defined as a lingua-franca variation (Seidlhofer 2011, due to the inclusion of specific verb tenses and the selection of simplified syntactic structures (Seidlhofer 2004, aimed at facilitating the audience’s reception and accessibility to the semantic dimensions of the text. Finally, the analysis will also highlight the translators’ attempts to respect the temporal and spatial constraints of subtitles (Neves 2009, as well as the multimodal construction (Kress and van Leeuwen 2006 of audiovisual texts, which result in the use of condensation strategies (Gottlieb 2005; Pedersen 2011, thus proposing the new definition of audiovisual mediation.

  2. Lingua-Pedagogy as the Interdisciplinary Research Problem

    A. N. Yakovleva

    2012-01-01

    Full Text Available  The paper is devoted to lingua-pedagogy – one of the modern branches of pedagogy dealing with personal socialization in the process of foreign language learning. This interdisciplinary field of knowledge is related to linguistics, pedagogic psychology, development psychology and acmeology. Lingua-pedagogy undergoes the formation process; therefore, there still are a number of open questions concerning its place among the other sciences, and the final definitions of the main concepts and terms. The author recommends the systematic approach to developing the theoretical foundation of lingua- pedagogy. The paper outlines the subject and aims of the lingua-pedagogic research, its content and affecting means. The system in question is poly- functional, its main functions being the integral pedagogic effect in foreign language teaching, stimulating self-dependent learning, and arranging the in- tercultural integration. The linguistic faculties at universities can be taken as the key elements of the lingua-pedagogic system – the development centers, nurturing the value-oriented respectful attitude to the native and foreign cul- ture, providing intercultural competence acquisition, and training pedagogic staff capable of fulfilling the poly-cultural development tasks. Identification of the conformities of intercultural socialization makes it possible to organize the system of pedagogic facilitation for students learning foreign languages; and develop the perspective methods and technologies of language competence acquisition and consolidation. 

  3. LINGUA-SEMIOTICS OF POWER RITUAL

    Astafurova Tatyana Nikolaevna

    2015-06-01

    Full Text Available The article deals with lingua-semiotic representation of the power ritual as one of the symbolic forms of behavior that over time ceases to be spontaneous and becomes regular and repeated. Under discussion is the rite of coronation, which was becoming more complicated and acquired a final form throughout the history of Anglo-Saxon statehood. The process of defining parameters and characteristics of the power ritual is performed by chrono-, topo-, sound and language components of the ritual; it is established that in ritual communication the verbalization of the event is gradually becoming more complicated, clarifying its linguistic component, which largely ensures the success of the ritual; the non-verbal signs acquire additional meaning becoming dominant over simplified verbal signs. It is proved that within the ritual space of the Anglo-Saxon statehood an extensive and rigidly fixed system of signs and symbols has been formed, nominating the process of interaction between the sovereign and his subjects – three groups of signs characterizing the Anglo-Saxon power ritual communication: regulating, processing and classifying signs. Their content distinction is analyzed. Authority widely applies these signs as tools to influence the society through social stereotypes and ethnic psychological associations. Artifacts, as symbols of state power, and oaths, as discursive element of the coronation, are stated as the central elements of the ritual.

  6. Lingua patientis: new words for patient communication and history taking.

    Weaver, Donald F

    2017-11-01

    The English language sometimes fails in its ability to describe the severity or complexity of medical symptoms and complaints. In frustration, patients (or families) occasionally create new words to convey the subtleties of their medical history. Although medicine has created a comprehensive technical lexicon for physicians, we have failed to develop a corresponding patient-centric vocabulary (lingua patientis) that provides more accurate symptom description. The social networking of lingua patientis words might enhance history taking and afford improved appreciation of disease impact on individual patients. The English language is renowned for its capacity for flexibility and adaptability - we need to exploit this capacity for the benefit of our patients.

  7. LA LINGUA PER STUDIARE: UNA RASSEGNA BIBLIOGRAFICA

    Marina Tassara

    2011-02-01

    Full Text Available I libri di testo adottati nelle scuole contengono parole sconosciute e costruzioni sintattiche e testuali complesse che rappresentano dei veri e propri “muri linguistici” per gli alunni stranieri che non possiedono una buona conoscenza della lingua italiana. Ciò facilmente determina un divario di competenze tra l’apprendente straniero e i suoi compagni e ritardi scolastici molto spesso incolmabili con conseguente perdita di motivazione e di autostima, senso di frustrazione e isolamento che a volte sfocia in un disagio psico-sociale. Tra gli strumenti adottati dalla scuola italiana per far fronte a questo problema vi sono i testi disciplinari ad alta comprensibilità che, pur mantenendo la maggior parte delle informazioni, le veicolano in una forma più semplice dal punto di vista linguistico. L’articolo fornisce una bibliografia di manuali ad alta comprensibilità il più possibile aggiornata suddivisa per ordine e grado di scuola e per materia scolastica, con l’intento di fornire agli insegnanti un aiuto nella scelta e nel reperimento dei testi.     Language for study:  a bibliography   Textbooks used in schools contain unknown words and complex sentence constructions that create real “linguistic barriers” for foreign students who do not know Italian well.  This creates an abyss between the competence of the foreign learner and his or her classmates and unsuccessful school performance which is often not made up for and leads to a loss of self-esteem, frustration, isolation, and ultimately to psycho-social malaise.  Among the tools utilized in the Italian school system to address this problem are highly comprehensible textbooks which, while containing most of the information, express the content in simpler language.  This article offers an up-dated bibliography of textbooks which are easily understandable, divided according to order and grade of school, for teachers to use in choosing the textbooks for their classes.

  12. "Piedra Franca": the same name for many different natural stones.

    Pereira, Dolores; Navarro, Rafael; Baltuille, Jose Manuel

    2014-05-01

    The Spanish name "Piedra Franca" refers to all the stones of sedimentary origin that have uniform coloration and easeof cutting/carving in order to obtain dimensional blocks for construction. The first references to this denomination occurred during medieval times, when builders had to choose the best materials to construct magnificent cathedrals. The largest volume of such natural stones were extracted from Caen, northern France, and historic records use the English term, "freestone", ie stone easy to cut, and to work by the masons dedicated to build cathedrals ("freemasons") in contrast to the "roughstone", hard stones worked by the hard hewers or "rough masons". The original French name referred to the limestones extracted at Caen, but over time, the original meaning expanded to include other natural stones with similar coloration and ease to carve. Notably this included many sandstones that were used in adjacent countries such as Spain. In the latter, although the most popular for its importance in architectural heritage is the Villamayor sandstone from Salamanca, other historically important natural stones are also known as "Piedra Franca" including the calcarenite from Santa Pudia (Granada), the limestone from Alava, the sandstone from Jaen and the sandstone from Cádiz. All of them were used in the construction of Spanish architectonic heritage and share similar exterior characteristics. In fact, several are known as golden stones. However when conservation and restoration of architectonic heritage is involved, the correct and original material should be used. The existence of national networks (e.g. CONSTRUROCK) and international task groups (e.g. IUGS Heritage Stone Task Group) can help to properly characterize, document, and differentiate between the varieties of "Piedra Franca" and they should be consulted by builders, architects and any other stone professsionals involved in such activities. An error in choosing the natural stone can result in

  17. ELF radiation from the Tromsoe super heater facility

    Barr, R.; Stubbe, P.

    1991-01-01

    Direct comparisons have been made of the ionospheric ELF radiation produced by the new (1 GW ERP) and old (250 MW ERP) antennas of the Tromsoe heater system, but no significant differences in the ELF signal strength have been detected. This initially surprising result is shown to require a value of unity for the index relating the received ELF signal strength to HF power input to the antenna. A series of experiments performed solely to derive more accurate values for this power index provided values ranging from 0.74 to 0.97, dependent on the ELF frequencies generated. It has been suggested that ELF radiation from the normal Tromsoe heater facility should be limited by saturation effects, even when operating well below the maximum HF power density (3mW/m 2 in the D-region). No evidence for such saturation effects has been found even at power densities greater than 10mW/m 2

  19. ELF magnetic therapy and oxidative balance.

    Raggi, Francesco; Vallesi, Giuseppe; Rufini, Stefano; Gizzi, Stefania; Ercolani, Enrico; Rossi, Ruggero

    2008-01-01

    Knowledge about the relationship between exposure to extremely low-frequency (ELF) EMF and formation (or neutralization) of free radicals in the living cells is limited. Studies performed on animals and plants have shown conflicting effects on the relation between EMF and oxidative stress. Very few experiments have been performed on humans. The present study reports on the effects of an ELF magnetic therapy device (Seqex) on oxidative scale in humans. This device supplies complex magnetic signals with specific choices of frequency, intensity, and shape that are based on Liboff's ion cyclotron resonance hypothesis. Thirty-two healthy volunteers were treated using the Seqex cycle. A quantitative determination of oxidative stress was obtained at three time points by measuring Malondialdehyde (MDA) concentrations in peripheral blood before and after the cycle and one month following completion of the cycle. A highly significant reduction in mean MDA (53.8%, p = 0.0002) was found at the end of the treatment. One month later the mean MDA had again risen, but there was still a significant overall reduction of 15.6% (p = 0.010) compared to original values.

    Elf has long since been aware of the potential of sedimentary basins in the ocean depths. For this reason, the group has been preparing to descend to these depths for many years. Today, it is setting itself the target of being ready to optimise as from 1997 a discovery made in the depth between 400 and 1500 m of water in Africa. In the Gulf of Guinea, most of the neighbouring countries have opened up their deep sea offshore areas, in order to try to renew their reserves on the verge of the third millennium. Indeed a great similarity can be seen between the West African and the Brazilian ocean depths. In the African offshore areas, Elf has acquired or renewed eight blocks, four of which are in Nigeria, one in the Congo, one in Gabon and two in Angola. The group is also interested in the ocean depths which are now accessible in the North Sea, whether in the Norwegian (Voring and More) of British (Western Shetlands) areas. (author). 1 fig

  7. Investigation of the radiation properties of magnetospheric ELF waves induced by modulated ionospheric heating

    Wang, Feng; Ni, Binbin; Zhao, Zhengyu; Zhao, Shufan; Zhao, Guangxin; Wang, Min

    2017-05-01

    Electromagnetic extremely low frequency (ELF) waves play an important role in modulating the Earth's radiation belt electron dynamics. High-frequency (HF) modulated heating of the ionosphere acts as a viable means to generate artificial ELF waves. The artificial ELF waves can reside in two different plasma regions in geo-space by propagating in the ionosphere and penetrating into the magnetosphere. As a consequence, the entire trajectory of ELF wave propagation should be considered to carefully analyze the wave radiation properties resulting from modulated ionospheric heating. We adopt a model of full wave solution to evaluate the Poynting vector of the ELF radiation field in the ionosphere, which can reflect the propagation characteristics of the radiated ELF waves along the background magnetic field and provide the initial condition of waves for ray tracing in the magnetosphere. The results indicate that the induced ELF wave energy forms a collimated beam and the center of the ELF radiation shifts obviously with respect to the ambient magnetic field with the radiation power inversely proportional to the wave frequency. The intensity of ELF wave radiation also shows a weak correlation with the size of the radiation source or its geographical location. Furthermore, the combination of ELF propagation in the ionosphere and magnetosphere is proposed on basis of the characteristics of the ELF radiation field from the upper ionospheric boundary and ray tracing simulations are implemented to reasonably calculate magnetospheric ray paths of ELF waves induced by modulated ionospheric heating.

  8. Multiflash whistlers in ELF-band observed at low latitude

    A. K. Singh

    2011-01-01

    Full Text Available Multiflash whistler-like event in the ELF-band, observed during March 1998 at low latitude station Jammu, is reported. The most prominent feature of these events is the multiflash nature along with the decrease in frequency within a very short span of time resembling similar to terrestrial whistlers. The events have a significantly smaller time duration (0.5–3.5 s than those reported earlier from high, mid and low latitudes and also display a diurnal maximum occurring around 09:30 h (IST. There have been similar reportings from other latitudes, but whistlers in the ELF-band with a multiflash nature along with a precursor emission have never been reported. Lightning seems to be the dominant source for the ELF whistlers reported here.

  9. ELF4 Regulates GIGANTEA Chromatin Access through Subnuclear Sequestration

    Yumi Kim

    2013-03-01

    Full Text Available Many organisms, including plants, use the circadian clock to measure the duration of day and night. Daily rhythms in the plant circadian system are generated by multiple interlocked transcriptional/translational loops and also by spatial regulations such as nuclear translocation. GIGANTEA (GI, one of the key clock components in Arabidopsis, makes distinctive nuclear bodies like other nuclear-localized circadian regulators. However, little is known about the dynamics or roles of GI subnuclear localization. Here, we characterize GI subnuclear compartmentalization and identify unexpected dynamic changes under diurnal conditions. We further identify EARLY FLOWERING 4 (ELF4 as a regulator of GI nuclear distribution through a physical interaction. ELF4 sequesters GI from the nucleoplasm, where GI binds the promoter of CONSTANS (CO, to discrete nuclear bodies. We suggest that the subnuclear compartmentalization of GI by ELF4 contributes to the regulation of photoperiodic flowering.

  10. An active antenna for ELF magnetic fields

    Sutton, John F.; Spaniol, Craig

    1994-01-01

    The work of Nikola Tesla, especially that directed toward world-wide electrical energy distribution via excitation of the earth-ionosphere cavity resonances, has stimulated interest in the study of these resonances. Not only are they important for their potential use in the transmission of intelligence and electrical power, they are important because they are an integral part of our natural environment. This paper describes the design of a sensitive, untuned, low noise active antenna which is uniquely suited to modern earth-ionosphere cavity resonance measurements employing fast-Fourier transform techniques for near-real-time data analysis. It capitalizes on a little known field-antenna interaction mechanism. Recently, the authors made preliminary measurements of the magnetic fields in the earth-ionosphere cavity. During the course of this study, the problem of designing an optimized ELF magnetic field sensor presented itself. The sensor would have to be small, light weight (for portable use), and capable of detecting the 5-50 Hz picoTesla-level signals generated by the natural excitations of the earth-ionosphere cavity resonances. A review of the literature revealed that past researchers had employed very large search coils, both tuned and untuned. Hill and Bostick, for example, used coils of 30,000 turns wound on high permeability cores of 1.83 m length, weighing 40 kg. Tuned coils are unsuitable for modern fast-Fourier transform data analysis techniques which require a broad spectrum input. 'Untuned' coils connected to high input impedance voltage amplifiers exhibit resonant responses at the resonant frequency determined by the coil inductance and the coil distributed winding capacitance. Also, considered as antennas, they have effective areas equal only to their geometrical areas.

  11. ELFE: New machine proposed for Europe

    Anon.

    1995-01-01

    Understanding the dynamics of non-perturbative QCD (the physics of quark and gluon interactions at large coupling) is one of the most challenging problems of modern physics. The two phenomena of quark confinement, which binds quarks permanently inside hadrons, and the dynamical breaking of chiral symmetry, which gives us pion physics and more massive constituent quarks of low energy QCD, define the interface of nuclear and particle physics. The Electron Laboratory for Europe project - ELFE - is the European machine initiative proposed as the optimum experimental tool to study this ''Confinement Physics'', which is virgin territory for both particle and nuclear physicists. Until recently, lack of data in the confinement domain had led to slow theoretical progress in understanding the quark structure of nuclear and hadronic matter. This situation has improved considerably, with new discoveries in high energy deep inelastic scattering experiments together with important advances in large acceptance detector technology and continuous electron beams at low energies. At high energies, the CERN muon beam experiments in deep inelastic scattering (probing the remote interior of nucleons) opened an exciting new window on nucleon structure with the discovery of three unexpected effects: the EMC (European Muon Collaboration) nuclear and spin effects, and the observation of a surprisingly large difference between the the number of anti-up and anti-down quarks in nucleons. In 1983, the EMC nuclear effect showed that the quark structure of the free nucleon is modified in the nuclear environment. The EMC spin effect (or proton spin problem) is the discovery that it looks as though quark spin contributes only 22% of that of the nucleon (July 1994, page 19)

    Full Text Available In questo contributo si analizzano, in un contesto di insegnamento/apprendimento dell’italiano L2, esempi di parlato del docente, a cui è affidata la gestione della comunicazione didattica, ed esempi di parlato degli apprendenti, osservando, in particolare, in quale modo la loro produzione orale e il loro coinvolgimento nell’interazione verbale in classe sia previsto e guidato dalla forma della lezione e dalle strutture dialogiche a cui è correlato l’apprendimento della lingua. Nell’analisi di parlato e di interazioni verbali in classe si sono riscontrati due modelli fondamentali: la lingua della conversazione, macro-obiettivo comunicativo di lezioni svolte nell’ambito del progetto “Marco Polo” presso l’Università degli Studi di Milano, e la lingua dell’esposizione, perseguito nelle lezioni dei corsi sull’italiano disciplinare L2, sempre promossi dall’UniMi, e denominati “CALP” (Cognitive Academic Language Proficiency. La scelta metodologica di riportare la trascrizione e l’analisi di un’intera lezione del progetto “Marco Polo” è motivata dalla convinzione che la lezione è l’unità che riassume tutti gli elementi costitutivi del discorso didattico. A questa analisi segue l’esame di campioni audio-video registrati durante le lezioni dei corsi CALP, per mostrare come l’insegnamento/apprendimento dell’italiano L2/LS possa richiedere diverse tipologie di materiali e strumenti che supportano il parlato dell’insegnante e facilitano la comunicazione di contenuti didattici tra insegnante e apprendenti, se usati coerentemente con i micro-obiettivi e macro-obiettivi della lezione.  Language teacher in-class speech In this paper we analyze examples of in-class teacher speech, responsible for managing the teaching communication, and examples of learners' speech in an Italian L2 teaching/learning context.

  14. Assessment of ELF magnetic fields produced by independent power lines

    Lucca, G.

    2008-01-01

    In this paper, the problem of assessing the ELF (extremely low-frequency) magnetic fields produced, in a certain area characterised by the presence of more than one independent power line, is faced. The use of the incoherent summation of the single contributions, as an advantageous estimator of the total magnetic field, is proposed and justified by means of a heuristic procedure. This kind of approach can be seen as a useful and practical tool to be employed in environmental impact analysis and in assessing long-term human exposure to ELF magnetic fields. (authors)

    Full Text Available Abstract – ELF used in immigration domains typically reflects the different cognitive and communicative processes as well as the power/status asymmetries involved in cross-cultural situations of unequal encounters between non-western supplicants (i.e., African immigrants and asylum seekers and western (Italian experts in authority. Such situations will be here explored with reference to institutional contexts where the conditions for achieving successful communication through the use of ELF variations are biased against the participants’ different native linguacultural backgrounds from which they appropriate English without conforming to native speaker norms of usage. A number of case studies will illustrate the extent to which features of ELF usages may be perceived as formally deviating and socio-pragmatically inappropriate in intercultural communication – this being due to the participants’ lack of acknowledgement of each other’s ELF variations – thus giving rise to misunderstandings that often raise social and ethical issues about inequality and social justice. More specifically, the case studies will enquire, on the one hand, into the processes by which ELF users transfer typological, textual, lexical and logical features of their native languages and cultures to the domain-specific communication they are involved in, thus affecting their pragmalinguistic behaviours and interpretative strategies, leading ultimately to communication failure. On the other hand, some case studies will enquire into possible ‘hybridization strategies’ of written reformulation aimed at making ELF discourse conceptually accessible and socio-pragmatically acceptable to immigrants and refugees involved in the interaction, by making it conform to their different native linguacultural backgrounds, with the ultimate purpose of achieving a ‘mutual accommodation’ of ELF variations in order to promote the social inclusion of marginalized immigrants as

  17. Sources of Exposure to ELF Fields at Workplaces (invited paper)

    Vecchia, P.

    1999-01-01

    In most workplaces people are exposed to a variety of extremely low frequency (ELF) fields. So-called 'electric jobs' have been identified, where the exposure is likely to significantly exceed average residential and occupational levels. The classification is, however, questionable, and no reliable exposure data may in general be associated with different jobs. Most recent epidemiological studies have been focused on areas where ELF fields are quite intense, sources are clearly identified, and actual field levels can be measured. Such areas include electric power generation, transmission and distribution, electric transport, and arc welding. In this paper, typical values of magnetic fields in these workplaces are presented and discussed. The time-weighted magnetic field values for the same jobs are not very consistent across the studies. This indicates that not only job titles, but also measurements of the magnetic field, are poor surrogates for the actual exposure, which is best assessed by the use of dosemeters. (author)

  18. Artificial excitation of ELF waves with frequency of Schumann resonance

    Streltsov, A. V.; Guido, T.; Tulegenov, B.; Labenski, J.; Chang, C.-L.

    2014-11-01

    We report results from the experiment aimed at the artificial excitation of extremely low-frequency (ELF) electromagnetic waves with frequencies corresponding to the frequency of Schumann resonance. Electromagnetic waves with these frequencies can form a standing pattern inside the spherical cavity formed by the surface of the Earth and the ionosphere. In the experiment the ELF waves were excited by heating the ionosphere with X-mode HF electromagnetic waves generated at the High Frequency Active Auroral Research Program (HAARP) facility in Alaska. The experiment demonstrates that heating of the ionosphere can excite relatively large-amplitude electromagnetic waves with frequencies in the range 7.8-8.0 Hz when the ionosphere has a strong F layer, the frequency of the HF radiation is in the range 3.20-4.57 MHz, and the electric field greater than 5 mV/m is present in the ionosphere.

  1. ULF/ELF Waves in Near-Moon Space

    Nakagawa, Tomoko

    2016-02-01

    The reflection of the solar wind protons is equivalent to a beam injection against the solar wind flow. It is expected to produce a ring beam with a 3D distribution function in many cases. The reflected protons are responsible for the generation of ultra-low-frequency (ULF) waves at ˜0.01 Hz and narrowband waves at ˜1 Hz in the extremely low frequency (ELF) range through resonant interaction with magnetohydrodynamic waves and whistler mode waves in the solar wind, respectively. This chapter discusses these commonly observed waves in the near-Moon space. The sinusoidal waveforms and sharp spectra of the monochromatic ELF waves are impressive, but commonly observed are non-monochromatic waves in the ELF range ˜0.03-10 Hz. Some of the solar wind protons reflected by the dayside lunar surface or crustal magnetic field gyrate around the solar wind magnetic field and can access the center of the wake owing to the large Larmour radius.

  2. Analysis of impulse signals with Hylaty ELF station

    Kulak, A.; Mlynarczyk, J.; Ostrowski, M.; Kubisz, J.; Michalec, A.

    2012-04-01

    Lighting discharges generate electromagnetic field pulses that propagate in the Earth-ionosphere waveguide. The attenuation in the ELF range is so small that the pulses originating from strong atmospheric discharges can be observed even several thousand kilometers away from the individual discharge. The recorded waveform depends on the discharge process, the Earth-ionosphere waveguide properties on the source-receiver path, and the transfer function of the receiver. If the distance from the source is known, an inverse method can be used for reconstructing the current moment waveform and the charge moment of the discharge. In order to reconstruct the source parameters from the recorded signal a reliable model of the radio wave propagation in the Earth-ionosphere waveguide as well as practical signal processing techniques are necessary. We present two methods, both based on analytical formulas. The first method allows for fast calculation of the charge moment of relatively short atmospheric discharges. It is based on peak amplitude measurement of the recorded magnetic component of the ELF EM field and it takes into account the receiver characteristics. The second method, called "inverse channel method" allows reconstructing the complete current moment waveform of strong atmospheric discharges that exhibit the continuing current phase, such as Gigantic Jets and Sprites. The method makes it possible to fully remove from the observed waveform the distortions related to the receiver's impulse response as well as the influence of the Earth-ionosphere propagation channel. Our ELF station is equipped with two magnetic antennas for Bx and By components measurement in the 0.03 to 55 Hz frequency range. ELF Data recording is carried out since 1993, with continuous data acquisition since 2005. The station features low noise level and precise timing. It is battery powered and located in the sparsely populated area, far from major electric power lines, which results in high

    2008-06-01

    Full Text Available MontyLingua, an integral part of ConceptNet which is currently the largest commonsense knowledge base, is an English text processor developed using Python programming language in MIT Media Lab. The main feature of MontyLingua is the coverage for all aspects of English text processing from raw input text to semantic meanings and summary generation, yet each component in MontyLingua is loosely-coupled to each other at the architectural and code level, which enabled individual components to be used independently or substituted. However, there has been no review exploring the role of MontyLingua in recent research work utilizing it. This paper aims to review the use of and roles played by MontyLingua and its components in research work published in 19 articles between October 2004 and August 2006. We had observed a diversified use of MontyLingua in many different areas, both generic and domain-specific. Although the use of text summarizing component had not been observe, we are optimistic that it will have a crucial role in managing the current trend of information overload in future research.

  5. ELF-MF exposure affects the robustness of epigenetic programming during granulopoiesis

    Extremely-low-frequency magnetic fields (ELF-MF) have been classified as “possibly carcinogenic” to humans on the grounds of an epidemiological association of ELF-MF exposure with an increased risk of childhood leukaemia. Yet, underlying mechanisms have remained obscure. Genome instability seems an unlikely reason as the energy transmitted by ELF-MF is too low to damage DNA and induce cancer-promoting mutations. ELF-MF, however, may perturb the epigenetic code of genomes, which is well-known to be sensitive to environmental conditions and generally deranged in cancers, including leukaemia. We examined the potential of ELF-MF to influence key epigenetic modifications in leukaemic Jurkat cells and in human CD34+ haematopoietic stem cells undergoing in vitro differentiation into the neutrophilic lineage. During granulopoiesis, sensitive genome-wide profiling of multiple replicate experiments did not reveal any statistically significant, ELF-MF-dependent alterations in the patterns of active (H3K4me2) and repressive (H3K27me3) histone marks nor in DNA methylation. However, ELF-MF exposure showed consistent effects on the reproducibility of these histone and DNA modification profiles (replicate variability), which appear to be of a stochastic nature but show preferences for the genomic context. The data indicate that ELF-MF exposure stabilizes active chromatin, particularly during the transition from a repressive to an active state during cell differentiation.

    This work aimed to evaluate the effect of suckling technique and slaughter age on Martina Franca donkey meat quality. Twenty Martina Franca male foals were involved in the trial. Foals naturally assumed colostrum within 4h from birth. Afterwards, 10 foals were partially artificially suckled (AS), and 10 foals were naturally suckled (NS). All the foals were weaned at 180d, then housed indoors and fed the same diet. Ten donkeys were slaughtered at 12months and the other 10 at the age of 18months. Samples of Longissimus thoracis et lumborum (LTL) were taken from each foal for chemical analysis, then rheological parameters, oxidative profile, colorimetric parameters and fatty acid profile were assessed. Older donkeys (18months) fed with natural milk presented the highest intramuscular fat (IMF) and meat protein content. From a dietary view point, IMF acid composition showed a more favourable profile in meat from artificially-reared donkeys compared to naturally-suckled ones. Copyright © 2017 Elsevier Ltd.

    Placental development is a complex and highly controlled process during which trophoblast stem cells differentiate to various trophoblast subtypes. The early embryonic death of systemic gene knockout models hampers the investigation of these genes that might play important roles during placentation. A trophoblast specific Cre mouse model would be of great help for dissecting out the potential roles of these genes during placental development. For this purpose, we generate a transgenic mouse with the Cre recombinase inserted into the endogenous locus of Elf5 gene that is expressed specifically in placental trophoblast cells. To analyze the specificity and efficiency of Cre recombinase activity in Elf5-Cre mice, we mated Elf5-Cre mice with Rosa26 mT/mG reporter mice, and found that Elf5-Cre transgene is expressed specifically in the trophoectoderm as early as embryonic day 4.5 (E4.5). By E12.5, the activity of Elf5-Cre transgene was detected exclusively in all derivatives of trophoblast lineages, including spongiotrophoblast, giant cells, and labyrinth trophoblasts. In addition, Elf5-Cre transgene was also active during spermatogenesis, from spermatids to mature sperms, which is consistent with the endogenous Elf5 expression in testis. Collectively, our results provide a unique tool to delete specific genes selectively and efficiently in trophoblast lineage during placentation. © 2018 Wiley Periodicals, Inc.

  12. Characterization of tannery sludge from the leather industry of Franca industrial district, SP, Brazil

    Chambi, M.M.; Toffoli, S.M.

    2011-01-01

    The industry of leather manufacture generates large quantities of solid leather waste with characteristics of high-polluting and hazardous conditions. Among these wastes, stands out the wet blue leather (chromed leather scraps), and the tanning sludge and secondary sludge generated in the processes of effluents treatment. These wastes contain Cr(III), which, under oxidizing conditions, can turn into Cr (VI), which is highly toxic. However, these wastes are a potential source of chromium oxide (traditional industrial pigment), which could be used by the glass and ceramic enamel industries. In this study, a preliminary characterization of a chromium sludge from the industrial district of Franca-SP was conducted. X-ray diffraction (XRD), chemical (XRF) and thermal (DTA / TG) analyses were used to determine the physical and chemical characteristics of this solid waste. The potential of using this material as an available and cheap pigment for the manufacture of enamels and glass is discussed. (author)

  14. Artificial suckling in Martina Franca donkey foals: effect on in vivo performances and carcass composition.

    De Palo, Pasquale; Maggiolino, Aristide; Milella, Paola; Centoducati, Nicola; Papaleo, Alessandro; Tateo, Alessandra

    2016-01-01

    In recent years, there has been an increasing interest on donkey milk production, on its characteristics, and also on breeding techniques. Donkey milk is characterized by high economic value, although the productive level of jennies is poor. During the milking process, foals are usually separated from their dams, allowing the milk collection in the mammary gland of jennies before milking session. This takes 8 h per day of fastening period for lactating donkey foals. During this period, it could be possible to apply a partial artificial suckling system (artificial suckling during daytime and natural suckling during the night). The aim of the work is the evaluation of the effect of this innovative technique on in vivo performances and on meat production traits of Martina Franca donkey foals. Forty Martina Franca jennies with their foals were used for the trial. After colostrum assumption, 20 foals were partially artificially suckled (AS) during each day, and 20 foals were naturally suckled (NS). From 8.00 to 20.00, both groups were separated from their mothers in order to allow the milking procedures of the jennies. The AS group was in a stall equipped with an automatic calf-suckling machine. For each group, 10 foals were slaughtered at 12 months and 10 foals at 18 months. Artificial suckling system positively affected the growth rate of donkey foals, particularly in the first 6 months from birth, with higher weekly weight gain (P  0.05). Artificial suckling system permitted to extend the time of foal separation from their mothers increasing milk collection time per day, awarding fastening periods in foals.

  15. Anaphora in question-answer sessions in university ELF contexts.

    Full Text Available Abstract - Identity chains (Hasan 1984 ˗ strings of co-referential noun phrases ˗ constitute a lesser researched area in the field of ELF, as has the more general area of cohesion (but see Hüttner 2009, Christiansen 2011. Following on the work on anaphora of such scholars as Reinhart (1983 and Cornish (1999, and on cohesion (e.g. Halliday and Hasan 1976, Halliday 2004, Christiansen (2009a/b, 2011 focuses on the link between text cohesion and discourse coherence. The interactive perspective of discourse (seen as the process of which text is the product: see Widdowson 1984: 100 is especially relevant to an ELF context of spontaneous spoken interaction. As Guido (2008 evidences, different inter-cultural concerns constitute a crucial dimension to the complex multi-code interaction. Consequently, the diverse ways in which speakers from different L1 backgrounds employ anaphors and construct identity chains are key elements in the co-construction of a dialogic text. In this case study, six extracts of transcripts taken from the VOICE corpus (2011 of conference question and answer sessions set in multicultural contexts are analysed qualitatively. The different ways that participants construct identity chains (e.g. whether they use full forms of various kinds or anaphoric pro-forms are classified. The analysis focuses on both how individual anaphors are resolved and how relations between anaphors and antecedent triggers are encoded, and how identity chains are constructed and organized individually. The objective is to identify which kinds of noun phrase (various subtypes of full and pro-forms are used by diverse groups of EFL speakers both in relation to their own contributions and to those of other speakers (with a threefold distinction made between the same turn of the same speaker, a different turn of the same speaker, and a different turn by a different speaker.

  17. Penetration of ELF currents and electromagnetic fields into the Earth's equatorial ionosphere

    Eliasson, B.; Papadopoulos, K.

    2009-10-01

    The penetration of extremely low frequency (ELF) transient electromagnetic fields and associated currents in the Earth's equatorial E-region plasma is studied theoretically and numerically. In the low-frequency regime, the plasma dynamics of the E-region is characterized by helicon waves since the ions are viscously coupled to neutrals while the electrons remain mobile. For typical equatorial E-region parameters, the plasma is magnetically insulated from penetration of very long timescale magnetic fields by a thin diffusive sheath. Wave penetration driven by a vertically incident pulse localized in space and time leads to both vertical penetration and the triggering of ELF helicon/whistler waves that carry currents obliquely to the magnetic field lines. The study presented here may have relevance for ELF wave generation by lightning discharges and seismic activity and can lead to new concepts in ELF/ULF injection in the earth-ionosphere waveguide.

A questo dato di fatto si deve senz'altro l'opinione altrettanto estesa che prima dell'800 non esistesse il concetto di linguistica diacronica o cambiamento linguistico in senso scientifico, come pure quella non meno erronea che la linguistica, come scienza, sia stata fondata solo nell'800.

  1. Phosphorylation of protein synthesis initiation factor 2 (elF-2) in the yeast Saccharomyces cerevisiae

    Romero, D.P.

    1986-01-01

    Initiation Factor 2 (elF-2) in the yeast Saccharomyces cerevisiae is comprised of 3 subunits. The control of protein synthesis in mammalian cells have been shown to involve the phosphorylation of the small (alpha) subunit by a specific protein kinase. Phosphorylation results in an inhibition of protein synthesis. In order to determine whether or not an analogous system is operative in yeast, the phosphorylation state of the alpha subunit of elF-2 in Saccharomyces was determined during various growth and nongrowth conditions. Cells were radiolabelled with 32 P and 35 S, and the whole cell lysates were analyzed by two dimensional gel electrophoresis. These experiments revealed that the smallest subunit (alpha, M/sub r/ = 31,000) is a phosphoprotein in vivo under a variety of growth and nongrowth conditions. This is in direct contrast to the pattern exhibited in mammalian cells. The fact that the small subunit of elF-2 in yeast is phosphorylated under a variety of physiological conditions indicates that such a covalent modification is important for some aspects of elF-2 function. In order to investigate this problem further, a protein kinase that specifically labels the alpha subunit of elF-2 in vitro was isolated. The kinase is not autophosphorylating, utilizes ATP as a phosphate donor, phosphorylates an exogenous protein, casein, modifies serine residues in elF-2, is cyclic nucleotide-independent, and is strongly inhibited by heparin

  2. DNA micro array analysis of yeast global genome expression in response to ELF-MF exposure

    Shimizu, K.; Yamamoto, T.; Ishibashi, T.; Kyoh, B.

    2002-01-01

    There is wide spread public concern over the possible health risk of ELF-MF. Electromagnetic fields may produce a variety of effects in several biological systems, including the elevation of cancer risk and reduction of cell growth. Epidemiological studies have shown weak correlations between the exposure to ELF and the incidence of several cancers, but negative studies have also been reported. Moreover, there are some reports that basic biological events such as the cell cycle and DNA replication were affected by exposure to MF. However, to date the molecular mechanism of the MF effect on living organism is not clear. In this study, we used yeast DNA micro array to examine the transcriptional profile of all genes in response to ELF-MF. A few years ago it was difficult to carry out a global gene expression study to identify important genes regarding ELF-MF, however, today DNA micro arrays allow gene regulation in response to high density ELF-MF exposure. Thus we used micro array to analyze changes in mRNA abundance during ELF-MF exposure

  3. Use of C. Elegans as a model organism for sensing the effects of ELF-EMFs

    Lacchini, A H; Everington, M L; Augousti, A T; Walker, A J [School of Life Sciences, Kingston University London (United Kingdom)

    2007-07-15

    For the past two decades, there have been concerns and controversy about the effects on human health of the increased exposure to extremely-low-frequency (ELF) electromagnetic fields (EMFs) resulting from electrification, in both residential and industrial settings. Several epidemiological studies have implicated ELF-EMFs averaging 0.4 {mu}mUTesla (T) or more in increased risk of cancer, especially childhood leukaemia [1,2]; there have also been many reports demonstrating effects of power-frequency EMFs on cells [outlined in 1,3]. Unfortunately, however, the precise mechanisms by which ELF-EMFs exert biological effects have proven difficult to define and results of various studies have often been hard to reproduce [1]. We believe that C. elegans offers an exciting opportunity to elucidate the effects of power-frequency EMFs on cell signalling pathways within the whole organism and are therefore investigating the effects of ELF-EMF exposure on MAPK signalling in intact worms and fertilized embryos. Through taking a targeted approach to studying the effects of ELF-EMF's on MAPK signalling in C. elegans we aim to gather data that is physiologically relevant. Presently, this research is at a preliminary stage of preparation, and more detailed results on the exposure of Caenorhabditis elegans to ELF-EMF radiation will be presented at the conference itself.

  5. Assessment of multiple frequency ELF electric and magnetic field exposure

    Leitgeb, N

    2008-01-01

    Electromagnetic fields both in daily life and at workplaces exhibit increasingly complex frequency spectra. Present spectral assessment rules proved to be too conservative for health risk assessment. This is because they are based on the assumption that cells would react like linear systems in terms of responding to a sum of frequencies by a sum of independent responses to each individual frequency. Based on numerical investigations with the Hodgkin-Huxley and the Frankenhaeuser-Huxley nerve cell models, it could be shown that accounting for the nonlinear behaviour of cellular excitation processes avoids considerable overestimation of simultaneous exposures to multiple frequency ELF electric and magnetic fields. Besides this, it could be shown that the role of phase relationships is less important than that assumed so far. The present assessment rules lead to non-compliances of marketed electric appliances. For general application, a nonlinear biology-based assessment (NBBA) rule has been proposed, validated and proven advantageous compared with ICNIRP's rule. While staying conservative it avoids unnecessary overestimation and demonstrates compliance even in cases of suspected non-conformities. It is up to responsible bodies to decide upon the adoption of this proposal and the potential need for implementing additional or reducing the already incorporated safety factors

  6. ELF-VLF communications through-the-Earth

    Buettner, H. M.; Burke, G. J.; Didwall, E. M.; Holladay, G.; Lytle, R. J.

    1985-06-01

    We use computer models and experiments to explore the feasibility of communication between points underground and on the Earth's surface. Emphasis is placed on ELF-VLF electromagnetic propagation through the Earth; nominally, we investigated propagation in the 200 Hz-30 kHz frequency range. The computer modeling included calculations of the fields of a point electric or magnetic source in a homogeneous half space or a stratified Earth. Initial results for an insulated antenna of finite length are also considered. The experiments involved through-the-Earth transmissions at two locations in Pennsylvania, both of which had large formations of limestone. Initial results indicate that information rates as high as kbits/s may be possible for subsurface depths of 300 m or less. Accuracy of these estimates depends on the electromagnetic propagation constants of the rock, the noise characteristics, and modulation scheme. Although a nuisance for evaluating through-the-Earth propagation, the existence of subsurface metal conductors can improve the transmission character of the site.

  7. Comparison of magnetic field meters used for Elf exposure measurement

    Magne, I.; Azoulay, A.; Lambrozo, J.; Souques, M.

    2006-01-01

    Objective The question of the biological effects of E.L.F. electromagnetic fields (50/60 Hz) has lead to many experimental and epidemiological works, in occupational exposure and in residential exposure. One of the main difficulties is to integrate the maximum of information about the environmental exposures during the everyday life without limitation to the exposure of the home. The objective of this study is to analyse experimentally the metrology associated with human exposure to 50 Hz magnetic field, in the optic of a study of the French population exposure. Method 4 meters were tested: the E.M.D.E.X. II, currently used in epidemiological studies, the E.M.D.E.X. L.I.T.E., which is more recent, the H.T.300, an Italian meter, and the F.D.3, which is made by Combinova A calibration was performed with an Helmoltz coil. The immunity of these meters to GSM signal was also tested. The influence of the sample rate was evaluated. Results and conclusion The meter chosen for performing the measurements of the exposure study will be selected in function of the following criteria: - easiness of use - precision - low sample rate - memory size and reliability of data stocking - immunity to GSM perturbations.

    2006-03-01

    To explore the clinical characteristics and speech therapy of 62 children with lingua-apical articulation disorder. Peabody Picture Vocabulary Test (PPVT), Gesell development scales (Gesell), Wechsler Intelligence Scale for Preschool Children (WPPSI) and speech test were performed for 62 children at the ages of 3 to 8 years with lingua-apical articulation disorder. PPVT was used to measure receptive vocabulary skills. GESELL and WPPSI were utilized to represent cognitive and non-verbal ability. The speech test was adopted to assess the speech development. The children received speech therapy and auxiliary oral-motor functional training once or twice a week. Firstly the target sound was identified according to the speech development milestone, then the method of speech localization was used to clarify the correct articulation placement and manner. It was needed to change food character and administer oral-motor functional training for children with oral motor dysfunction. The 62 cases with the apical articulation disorder were classified into four groups. The combined pattern of the articulation disorder was the most common (40 cases, 64.5%), the next was apico-dental disorder (15 cases, 24.2%). The third was palatal disorder (4 cases, 6.5%) and the last one was the linguo-alveolar disorder (3 cases, 4.8%). The substitution errors of velar were the most common (95.2%), the next was omission errors (30.6%) and the last was absence of aspiration (12.9%). Oral motor dysfunction was found in some children with problems such as disordered joint movement of tongue and head, unstable jaw, weak tongue strength and poor coordination of tongue movement. Some children had feeding problems such as preference of eating soft food, keeping food in mouths, eating slowly, and poor chewing. After 5 to 18 times of therapy, the effective rate of speech therapy reached 82.3%. The lingua-apical articulation disorders can be classified into four groups. The combined pattern of the

  10. A Novel Detection Method for Underwater Moving Targets by Measuring Their ELF Emissions with Inductive Sensors

    Jinhong Wang

    2017-07-01

    Full Text Available In this article, we propose a novel detection method for underwater moving targets by detecting their extremely low frequency (ELF emissions with inductive sensors. The ELF field source of the targets is modeled by a horizontal electric dipole at distances more than several times of the targets’ length. The formulas for the fields produced in air are derived with a three-layer model (air, seawater and seafloor and are evaluated with a complementary numerical integration technique. A proof of concept measurement is presented. The ELF emissions from a surface ship were detected by inductive electronic and magnetic sensors as the ship was leaving a harbor. ELF signals are of substantial strength and have typical characteristic of harmonic line spectrum, and the fundamental frequency has a direct relationship with the ship’s speed. Due to the high sensitivity and low noise level of our sensors, it is capable of resolving weak ELF signals at long distance. In our experiment, a detection distance of 1300 m from the surface ship above the sea surface was realized, which shows that this method would be an appealing complement to the usual acoustic detection and magnetic anomaly detection capability.

  11. ELF Transients and Q-bursts Detected Around the Globe: First results from Palmer Station, Antarctica

    Flint, Q. A.; Moore, R. C.

    2016-12-01

    We present the first analysis of data from the recently deployed broadband ELF (5-500 Hz) B-field receiver at Palmer Station, Antarctica together with observations at similar receivers located at Sondrestromfjord, Greenland and Arrival Heights, Antarctica. Such remote locations afford the unique opportunity to record signals that are essentially unperturbed by power line noise. As a result, using this multi-site global network of ELF/VLF receivers, we are able to easily detect a particular type of ELF transient that propagates around the world multiple times, known as the Q-burst. The Q-burst is characterized by a large increase in amplitude above the background at the Schumann Resonance modes and is believed to result from especially powerful cloud-to-ground lightning discharges. These powerful lightning discharges are likely responsible for a significant level of energetic coupling between the troposphere, the ionosphere, and the magnetosphere. The ELF and VLF waves excited by the lightning discharge propagate to great distances in the earth-ionosphere waveguide, and in fact propagate around the Earth multiple times. By measuring the received waveform at multiple distant sites around the globe, we can pinpoint the source lightning location, compare the changes in field strength and spectrum as a function of distance from the source, and evaluate modal propagation effects in the VLF range (that are not apparent in the ELF range).

    Wang Jiang; Zhang Ting; Che Yanqiu

    2007-01-01

    Chaos control and synchronization of two unidirectional coupled neurons exposed to ELF electrical field via nonlinear control technique is investigated. Based on results of space-time characteristics of trans-membrane voltage, the variation of cell trans-membrane voltage exposed to extremely low frequency (ELF) electric field is analyzed. The dynamical behaviors of the modified Hodgkin-Huxley (HH) model are identified under the periodic ELF electric field using both analytical and numerical analysis. Then, using the results of the analysis, a nonlinear feedback linearization control scheme and a modified adaptive control strategy are designed to synchronize the two unidirectional coupled neurons and stabilize the chaotic trajectory of the slave system to desired periodic orbit of the master system. The simulation results demonstrated the efficiency of the proposed algorithms

  13. Exposure estimates based on broadband elf magnetic field measurements versus the ICNIRP multiple frequency rule

    Paniagua, Jesus M.; Rufo, Montana; Jimenez, Antonio; Pachon, Fernando T.; Carrero, Julian

    2015-01-01

    The evaluation of exposure to extremely low-frequency (ELF) magnetic fields using broadband measurement techniques gives satisfactory results when the field has essentially a single frequency. Nevertheless, magnetic fields are in most cases distorted by harmonic components. This work analyses the harmonic components of the ELF magnetic field in an outdoor urban context and compares the evaluation of the exposure based on broadband measurements with that based on spectral analysis. The multiple frequency rule of the International Commission on Non-ionizing Radiation Protection (ICNIRP) regulatory guidelines was applied. With the 1998 ICNIRP guideline, harmonics dominated the exposure with a 55 % contribution. With the 2010 ICNIRP guideline, however, the primary frequency dominated the exposure with a 78 % contribution. Values of the exposure based on spectral analysis were significantly higher than those based on broadband measurements. Hence, it is clearly necessary to determine the harmonic components of the ELF magnetic field to assess exposure in urban contexts. (authors)

    Full Text Available Abstract Background Many factors act simultaneously in childhood to influence health status, life chances and well being, including pre-birth influences, the environmental pollutants of early life, health status but also the social influences of family and school. A cohort study is needed to disentangle these influences and explore attribution. Methods Elfe will be a nationally representative cohort of 20 000 children followed from birth to adulthood using a multidisciplinary approach. The cohort will be based on the INSEE Permanent Demographic Panel (EDP established using census data and civil records. The sample size has been defined in order to match the representativeness criteria and to obtain some prevalence estimation, but also to address the research area of low exposure/rare effects. The cohort will be based on repeated surveys by face to face or phone interview (at birth and each year as well as medical interview (at 2 years and examination (at 6 years. Furthermore, biological samples will be taken at birth to evaluate the foetal exposition to toxic substances, environmental sensors will be placed in the child's homes. Pilot studies have been initiated in 2007 (500 children with an overall acceptance rate of 55% and are currently under progress, the 2-year survey being carried out in October this year. Discussion The longitudinal study will provide a unique source of data to analyse the development of children in their environment, to study the various factors interacting throughout the life course up to adulthood and to determine the impact of childhood experience on the individual's physical, psychological, social and professional development.

    Proposals for ELFE (Electron Laboratory For Europe), a 15-30 GeV high luminosity, continuous beam electron accelerator are discussed. These proposals form an extensive research program on exclusive reactions to probe the evolution of correlated quarks systems. Using the nucleus itself as a microscopic detector is one of the important ideas of this program. The same reaction is measured using nuclei of different sizes and thus the differences are observed in the evolution from quarks and gluons to hadrons in the nuclear medium.

  18. Interaction of biological systems with static and ELF electric and magnetic fields

    Anderson, L.E.; Kelman, B.J.; Weigel, R.J. (eds.)

    1987-01-01

    Although background levels of atmospheric electric and geomagnetic field levels are extremely low, over the past several decades, human beings and other life forms on this planet have been subjected to a dramatically changing electromagnetic milieu. An exponential increase in exposure to electromagnetic fields has occurred, largely because of such technological advances as the growth of electrical power generation and transmission systems, the increased use of wireless communications, and the use of radar. In addition, electromagnetic field generating devices have proliferated in industrial plants, office buildings, homes, public transportation systems, and elsewhere. Although significant increases have occurred in electromagnetic field strenghths spanning all frequency ranges, this symposium addresses only the impact of these fields at static and extremely low frequencies (ELF), primarily 50 and 60 Hz. This volume contains the proceedings of the symposium entitled /open quotes/Interaction of biological systems with static and ELF electric and magnetic fields/close quotes/. The purpose of the symposium was to provide a forum for discussions of all aspects of research on the interaction of static and ELF electromagnetic fields with biological systems. These systems include simple biophysical models, cell and organ preparations, whole animals, and man. Dosimetry, exposure system design, and artifacts in ELF bioeffects research were also addressed, along with current investigations that examine fundamental mechanisms of interactions between the fields and biological processes. Papers are indexed separately.

    Full Text Available Introduction: Chronic exposure of non-ionizing extremely low-frequency magnetic fields (ELF-EMF is considered as a health hazard due to its adverse effects on human body such as generation of any type of cancer. Stem cells are appropriate models to assess the effects of ELF-EMF on other cell lines and human beings. Materials and methods: Adipose tissue has been known as source of multi potent stromal human mesenchymal stem cells (MSCs which can be obtained in less invasive method and in large amounts; so adipose-derived stem cells (ADSCs were used in this study. Effect of ELF-EMF (intensities of 0.5 and 1 mT and 50 Hz on proliferation rate of hADSCs was assessed in 20 and 40 min per day for 7 days. Trypan blue assay was performed to assess cell proliferation rate. Result: The results shown that 0.5 and 1 mT magnetic fields can promote the proliferation rate of adipose derived hMSCs according to the duration of exposure. Conclusion: These outcomes could approve the effect of ELF-EMF on cancer induction; although the effective mechanisms in this process are still unknown.

  20. A survey of ELF and VLF research on lightning-ionosphere interactions and causative discharges

    Inan, U. S.; Cummer, S. A.; Marshall, R. A.

    2010-06-01

    Extremely low frequency (ELF) and very low frequency (VLF) observations have formed the cornerstone of measurement and interpretation of effects of lightning discharges on the overlying upper atmospheric regions, as well as near-Earth space. ELF (0.3-3 kHz) and VLF (3-30 kHz) wave energy released by lightning discharges is often the agent of modification of the lower ionospheric medium that results in the conductivity changes and the excitation of optical emissions that constitute transient luminous events (TLEs). In addition, the resultant ionospheric changes are best (and often uniquely) observable as perturbations of subionospherically propagating VLF signals. In fact, some of the earliest evidence for direct disturbances of the lower ionosphere in association with lightning discharges was obtained in the course of the study of such VLF perturbations. Measurements of the detailed ELF and VLF waveforms of parent lightning discharges that produce TLEs and terrestrial gamma ray flashes (TGFs) have also been very fruitful, often revealing properties of such discharges that maximize ionospheric effects, such as generation of intense electromagnetic pulses (EMPs) or removal of large quantities of charge. In this paper, we provide a review of the development of ELF and VLF measurements, both from a historical point of view and from the point of view of their relationship to optical and other observations of ionospheric effects of lightning discharges.

  1. World map of ELF/VLF emissions as observed by a low-orbiting satellite

    Parrot, M.

    1990-01-01

    Statistical studies were performed of the intensities of the ELF/VLF emissions observed by the low-orbiting satellite AUREOL-3. Data were obtained from filterbanks and the frequency range of observations extends from a few tens of Hz up to 15 kHz. The most important phenomena observed are ELF hiss and VLF hiss. Electric and magnetic components are used. Thus, representation of the waves intensities in geographical coordinates was made at different frequencies. The relative ability of natural waves (whistler, hiss) and man-made waves, such as powerful VLF transmitters or powerline harmonic radiations (PLHR), to precipitate particles in the slot region, is studied. Using geomagnetical representation, it is shown that ELF hiss is maximum between 06 and 20 Magnetic Local Time and in the invariant latitude range 50 0 -70 0 as usual, but geographic representation indicates that the waves are intensified at the longitudes of VLF transmitters and near the South Atlantic Anomaly (SAA). The SAA plays a dominant role in the localization of the strongest ELF hiss. Weakest intensities are observed to the east of the SAA. As to the VLF hiss, the maximum intensity is related to regions of enhanced thunderstorm activity, and may be influenced by powerline harmonic radiations (PLHR) over USA. Comparisons with past work, experimental as well as theoretical, are made

  3. ELF and VLF signatures of sprites registered onboard the low altitude satellite DEMETER

    J. Błęcki

    2009-06-01

    Full Text Available We report the observation of ELF and VLF signature of sprites recorded on the low altitude satellite DEMETER during thunderstorm activity. At an altitude of ~700 km, waves observed on the E-field spectrograms at mid-to-low latitudes during night time are mainly dominated by up-going 0+ whistlers. During the night of 20 July 2007 two sprites have been observed around 20:10:08 UT from the observatory located on the top of the mountain Śnieżka in Poland (50°44'09" N, 15°44'21" E, 1603 m and, ELF and VLF data have been recorded by the satellite at about 1200 km from the region of thunderstorm activity. During this event, the DEMETER instruments were switched in the burst mode and it was possible to register the wave forms. It is shown that the two sprites have been triggered by two intense +CG lightning strokes (100 kA occurring during the same millisecond but not at the same location. Despite the distance DEMETER has recorded at the same time intense and unusual ELF and VLF emissions. It is shown that the whistler wave propagates from the thunderstorm regions in the Earth-ionosphere guide and enters in the ionosphere below the satellite. They last several tens of milliseconds and the intensity of the ELF waveform is close to 1 mV/m. A particularly intense proton whistler is also associated with these emissions.

  4. What advice to give when ELF is classified as a possible human carcinogen

    Repacholi, M.

    2002-01-01

    In 1996, the World Health Organization (WHO) established the International Electromagnetic Fields (EMF) Project to address the health issues associated with exposure to EMF. This Project is intended to provide independent scientific assessment of health effects from exposure to EMF (0-300 GHz); identify gaps in knowledge requiring further research in order to improve health risk assessments; encourage focused, high quality research; and conduct formal WHO/IARC/ICNIRP health risk assessments after key research has been completed. The International EMF Project is currently reviewing research results and conducting risk assessments of exposure to static and extremely low frequency (ELF) electric and magnetic fields. WHO will be conducting an evaluation of all health effects from ELF field exposure during 2002-3. This paper summarizes what is known about ELF exposure on childhood leukaemia, what the IARC classification means and how some national authorities have responded. In addition, WHO recommendations are given to provide guidance to national authorities wanting to protect their populations against EMF exposure. Whenever electricity is conducted through transmission lines, distribution lines or is used in appliances, both electric and magnetic fields exist close to the lines or appliances. The power frequency used is 50 or 60 Hz. Use of electric power has become part of everyday life. However, questions have been raised as to whether these and other ELF fields are carcinogenic or can produce any other effects on health

  6. Investigation of exposure to Extremely Low Frequency (ELF) magnetic and electric fields: Ongoing animal studies

    Anderson, L.E.

    1994-03-01

    There is now convincing evidence from a large number of laboratories, that exposure to extremely low frequency (ELF) magnetic and electric fields produces biological responses in animals. Many of the observed effects appear to be directly or indirectly associated with the neural or neuroendocrine systems. Such effects include increased neuronal excitability, chemical and hormonal changes in the nervous system, altered behavioral responses, some of which are related to sensing the presence of the field, and changes in endogenous biological rhythms. Additional indices of general physiological status appear relatively unaffected by exposure, although effects have occasionally been described in bone growth and fracture repair, reproduction and development, and immune system function. A major current emphasis in laboratory research is to determine whether or not the reported epidemiological studies that suggest an association between EMF exposure and risk of cancer are supported in studies using animal models. Three major challenges exist for ongoing research: (1) knowledge about the mechanisms underlying observed bioeffects is incomplete, (2) researchers do not as yet understand what physical aspects of exposure produce biological responses, and (3) health consequences resulting from ELF exposure are unknown. Although no animal studies clearly demonstrate deleterious effects of ELF fields, several are suggestive of potential health impacts. From the perspective of laboratory animal studies, this paper will discuss biological responses to ELF magnetic and/or electric field exposures.

    Extremely low frequency electromagnetic field ( ELF EMF) radiation falls under category of non-ionising radiation (NIR).ELF EMF consists of electric and magnetic fields. Excessive exposure to ELF EMF radiation may cause biological and health effects to human beings such as behavioral changes, stochastic and as initiator of cancer. In daily life, the main source of extremely low frequency electromagnetic radiation are consumer products in our home and office. Due to its ability to cause hazard, a study of ELF EMF radiation produced by consumer product was conducted. For this preliminary study, sample of 20 types electrical appliances were selected. The measurement was covered electric and magnetic field strength produced by the sample. PMM model EHP50A were used for measurement and data analysis. The results were compared with the permissible limits recommended by International Commission of Non-Ionising Radiation Protection (ICNIRP) for members of public (1000 mGauss and 5000 V/m). The results showed that all tested sample produced magnetic and electric field but still under the permissible limit recommended by ICNIRP. Besides that we found that field strengths can be very high at closer distance to the sample. (Author)

    Data obtained in newborn mice show that the chronic exposure during intra-uterine life to a 50 Hz, 650 μT E.L.F. magnetic field induce a genetic damage. Nevertheless, the increase of DNA strand break in brain and in micronuclei frequency in peripheral blood and liver disagree with the data obtained by Abramsson-Zetterberg and Grawe (13) which did not find any genetic alterations in mice exposed to extremely low frequency (E.L.F.) magnetic field. In any case, along with other dissimilarities in the experimental design, the intensity of the field (14 μT) and the time of sampling (35 days) were different. It is important to underline the four-fold increase in C.R.E.S.T.+ micronuclei frequency in circulating erythrocytes in the exposed group in comparison with the control group. Even though this value is quite low, it could indicate that E.L.F. magnetic fields may have different properties to damage the genome integrity. This stresses the need for further investigation on the possible link between electromagnetic fields and aneuploidy in order to elucidate the relationship with carcinogenesis. Preliminary data obtained with sperm abnormality assay show a significant increase of sperm abnormalities in mice exposed to E.L.F. magnetic fields and suggest a possible alteration to the spermatogenic process after exposure. This data agrees with data obtained by Tablado et al. (1998), in mice exposed continually for 35 days to a field of 1 T. Regarding the palatal ridges alterations assay, the results obtained show that the development of the secondary palate is not affected by E.L.F. magnetic field (50 Hz, 0,65 T). Nevertheless further studies at different frequency and intensity should be carried out to detect the possible epigenetic damage induced by E.L.F. exposure (Migliorini, 2005). With regard to the mechanism of action, it is generally believed that the damage induced by the magnetic field is an oxidative damage and that free radicals are involved. Some authors

    The expression of E74-like factor 5 (ELF5) in epithelial ovarian carcinoma tissues and its effects on biological behavior in ovarian carcinoma cells were assessed in search for a new approach for gene treatment of epithelial ovarian carcinoma. RT-PCR technology was applied to detect the expression of ELF5 mRNA in epithelial ovarian carcinoma (n=49), borderline ovarian epithelial tumor (n=19), benign ovarian epithelial tumor (n=31) and normal ovarian tissues (n=40). Then, we transfected recombinant plasmid pcDNA3.1‑ELF5+EGFP into human ovarian carcinoma SKOV3 cells (recombinant plasmid group) in vitro and screened out stably transfected cells to conduct multiplication culture. Western blot analysis was performed to detect the expression of ELF5 protein in the different groups. Flow cytometry was employed to detect cell apoptosis and cycles. ELF5 mRNA in epithelial ovarian carcinoma and borderline ovarian epithelial tumor tissues were significantly lower (Pepithelial tumor and normal ovarian tissues. ELF5 protein expression in the cells of recombinant plasmid group was significantly higher compared with empty plasmid and blank control groups. The capacity of cell reproductive recombinant plasmid group at each time point decreased (P<0.05). Flow cytometry detection showed that 67.03% of cells in recombinant plasmid group was blocked in G0/G1 phase (P<0.05), compared with empty plasmid group (37.17%) and blank control group (38.24%). Apoptotic rate of recombinant plasmid group was significantly lower (31.4±1.9%; P<0.05), compared with that of empty plasmid group (9.1±2.2%) and blank control group (8.7±1.5%), and the differences were statistically significant. In conclusion, ELF5 interfered with cell cycle of human ovarian carcinoma SKOV3 cells and promoted apoptosis of human ovarian carcinoma SKOV3 cells inhibiting their growth and invasive capacity; and thus providing a new approach to gene treatment of ovarian carcinoma.

    In the recent years, the donkey population decreased dramatically so that many breeds are presently considered as endangered. In comparison to the horse, the donkey placenta still remains not completely studied. In the horse, one of the diagnostic tools useful to identify pregnant mares at risk of abortion or premature delivery, include the transrectal ultrasound examination of the uterus and its contents; and especially of the combined thickness of the uterus and of the placenta (CUPT). Since the CUPT was never investigated in donkeys, the present study was aimed to define the transrectal CUPT values during the last half of pregnancy in 20 Martina Franca jennies. Foalings times, foals characteristics and placental gross appearance, and measurements were also evaluated and values resulted always within normality. Differently to the mare, a continuous significant CUPT increase between the sixth to the 12 months of pregnancy, and a substantial increase from the ninth to the 12th month of pregnancy, was found. Although statistically not evaluable, the CUPT values recorded from three jennies with pregnancy loss did not show evidence of CUPT increases. In conclusion, normal CUPT values from the sixth to the 12th month of pregnancy in Martina Franca donkeys are provided, but further investigations are needed to define possible breed or body-size CUPT specific differences, as well as the CUPT values during pregnancy disturbances or placental abnormalities.

    2007-07-01

    An artificial neural network (ANN) was developed to determine the electromagnetic field (EMF) and extremely low frequency (ELF) intensity on a vehicle body at different distances from a high tension power line and at varying power loads. EMF radiated emissions from ELF source power transmission lines can produce interference in the electric components in vehicles traveling at variable speed near the power lines. The passengers in the vehicle may also experience EMF-related health problems. Although EMF has been recently categorized as a new form of pollution, the situation has been largely ignored by the industry. Typically, electromagnetic fields at different frequencies show the fastest growing environmental influences. All populations are now exposed to varying degrees of EMF and the levels will continue to increase as technology advances. The purpose of this work was to promote discussion and help find design solutions to manufacture a new device for measuring the EMF at variable speed. In this study, a set of near field measurements outside the vehicle were used to train ANN. Estimations of the EMF ELF for various distances from the high tension power line were presented. It was determined that the most important factors affecting the electric field model include exposure conditions; size, shape and position of the exposed body in the field; and, surface charge density. The EMF ELF was found to increase near sagging areas of the overhead power transmission line. The EMF ELF was found to be proportional to the total amps flowing through the line at the time of measurement. 14 refs., 3 figs.

Questo articolo illustra i primi risultati di un progetto di ricerca in corso presso l’Università di Warwick, Regno Unito, (in collaborazione con l’Università di Monash, Australia che riguarda l’uso della traduzione collaborativa nell’insegnamento delle lingue a studenti universitari e a studenti Erasmus. Le autrici si sono concentrate sui vantaggi in termini di sensibilità linguistica e consapevolezza culturale derivanti da un particolare modello di traduzione collaborativa. Quando la proposta di “Collaborative Translation: A Model for Inclusion” si applica al particolare contesto della didattica delle lingue, infatti, l’insegnante e gli studenti esplorano insieme il processo di traduzione di un testo verso la lingua madre degli studenti. Il valore di questo approccio risiede nel privilegiare una messa in discussione della corrispondenza univoca tra due termini in due diverse lingue: l’insegnante è infatti un collaboratore della traduzione che agisce come facilitatore, chiedendo agli studenti-collaboratori di assumersi la responsabilità della traduzione. L’abilità linguistica in sé, di conseguenza, ha un ruolo secondario rispetto alla curiosità e alla riflessione linguistica nei confronti della propria lingua. I  workshop di inglese e di italiano sono stati rivolti rispettivamente a studenti principianti e a studenti avanzati.

    2008-12-01

    Full Text Available Dados recentes nos comprovam que as indústrias de lingerie têm apresentado considerável crescimento na cidade de Franca/SP, cuja história sempre se pautou pela indústria do calçado. Devido à crise no setor calçadista, sobretudo em razão da intensificação da concorrência com a indústria dos países asiáticos, muitas grandes fábricas de calçados foram fechadas e, com a dispensa de mão-de-obra, houve um processo de reorganização da estrutura fabril, protagonizado, em especial, por aqueles que buscavam nova inserção no mercado de trabalho. Diante deste quadro nasce uma nova vocação empresarial comandada basicamente por mulheres, e que está abrindo postos de trabalho para outras mulheres - a indústria de lingerie, que vem crescendo notoriamente. Partimos de um pressuposto inicial de que muitas destas mulheres, hoje à frente da incipiente indústria de lingerie, tiveram alguma experiência pregressa nas indústrias calçadistas, que empregam expressiva mão-de-obra feminina, sobretudo nos setores de apara e corte de couro, pintura e embalagem, sem contar os serviços do terceiro setor em que a presença feminina é, em qualquer circunstância, relevante. Já por estarem num ambiente econômico-industrial relacionado à moda, a transposição do calçado para a lingerie, em que pese as diferenças óbvias, representou para estas mulheres um reajuste em suas antigas qualificações como industriárias do calçado. Este estudo, em andamento, tem como fito levantar dados a respeito do histórico dessa incipiente indústria, e, através do relato dessas mulheres, conhecer suas trajetórias de vida e as experiências que trouxeram para essa nova realidade. Intenta também reconhecer quais foram as estratégias utilizadas para se reorganizarem nos espaços produtivos, que, em alguns casos é a própria casa, além de conhecer e identificar outras experiências que se articulam, no mundo do trabalho.

The borrowed elements in the city ergonyms register synchronous state of axiological determinants of participants of interaction: individuals, organizations and companies that create public and commercial signs. The common significance of the language of this kind of phenomena is determined by the possibility of using them to predict the range and diversity of linguistic and axiological changes, including the partial loss of national and ethnic identity. To create a high perlocutionary effect of ergonyms nominators use a variety of creative mechanisms, changing the shape and functions of native lexems, by borrowing lexems from foreign languages, resorting to different methods of derivation such as contamination, transliteration, hybridization, pun, etc. Unfortunately, at present time these processes demonstrate fast increase. The majority of them are not followed by gradual and harmonious integration into the host (Russian and Tatar cultures, but the erosion of values or partial /complete loss of identity is noted. Most clearly this kind of phenomenon is explicated in preferred nominator names of urban sites, and advertising slogans, transmitting an alien principles and postulates to traditional Russian culture.

    The industry of leather manufacture generates large quantities of solid leather waste with characteristics of high-polluting and hazardous conditions. Among these wastes, stands out the wet blue leather (chromed leather scraps), and the tanning sludge and secondary sludge generated in the processes of effluents treatment. These wastes contain Cr(III), which, under oxidizing conditions, can turn into Cr (VI), which is highly toxic. However, these wastes are a potential source of chromium oxide (traditional industrial pigment), which could be used by the glass and ceramic enamel industries. In this study, a preliminary characterization of a chromium sludge from the industrial district of Franca-SP was conducted. X-ray diffraction (XRD), chemical (XRF) and thermal (DTA / TG) analyses were used to determine the physical and chemical characteristics of this solid waste. The potential of using this material as an available and cheap pigment for the manufacture of enamels and glass is discussed. (author)

    The annual production of the Dunkerque`s refinery (France) represents 330000 t of lubricants, 16000 t of paraffins, 17000 t of wax, 34000 t of extracts, 304000 t of diesel fuel and 300000 t of bitumens. From the legal aspect, Mobil is operator of the unit which belongs to an independent company held by BP (60%) and Elf (40%). After the BP-Mobil agreement was signed, the Dunkerque`s refinery entered into new Mobil`s network of 6 lubricants refineries which represent an overall over-capacity of 400000 t/year. This over-capacity is a consequence of export limitations due to profits reduction. (J.S.)

  2. Utility of the ELF Test for Detecting Steatohepatitis in Morbid Obese Patients with Suspicion of Nonalcoholic Fatty Liver Disease.

    Morbid obese patients have a high rate of nonalcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). NASH is related to the progression and poor evolution of chronic hepatopathy in NAFLD, so that its detection makes it possible to identify the subjects who are most at risk in order to prioritize treatment. The ELF test (Enhanced Liver Fibrosis test; Siemens Diagnostics, NY, USA) has been assessed for its capacity to detect fibrosis in patients with NAFLD, but its capacity for diagnosing NASH has not been checked. Our objective is to determine the utility of the ELF test for detecting NASH in morbid obese patients with suspected NAFLD. ELF values were determined in a cohort of obese patients who underwent bariatric surgery with suspected NAFLD. Liver biopsy was used as the reference standard. The values of ELF were significantly higher in patients with NASH (p = 0.002) and in those who presented with metabolic syndrome (p = 0.047). An ELF cut-off point of 8.72 allows the detection of patients with NASH with a sensitivity of 71.4% and a specificity of 74.1% (AUC = 0.742, p = 0.002). The ELF test is efficient for the identification of obese patients with NAFLD and early signs of steatohepatitis and fibrosis.

  4. ELF waves and ion resonances produced by an electron beam emitting rocket in the ionosphere

    Winckler, J.R.; Abe, Y.; Erickson, K.N.

    1986-01-01

    Results are reported from the ECHO-6 electron-beam-injection experiment, performed in the auroral-zone ionosphere on March 30, 1983 using a sounding rocket equipped with two electron guns and a free-flying plasma-diagnostics instrument package. The data are presented in extensive graphs and diagrams and characterized in detail. Large ELF wave variations, superposed on the strong beam-sector-directed quasi-dc component, are observed in the 100-eV beam-induced plasma when the beam is injected in a transverse spiral, but not when it is injected upward parallel to the magnetic-field line. ELF activity is found to be suppressed whenever the rocket passed through field lines with auroral activity, suggesting that the waves are produced by the interaction of the beam potentials, plasma currents, and return currents neutralizing the accelerator payload. 12 references

    Two rocket KOMBI-SAMA experiments with plasma injection at height 100-240 km were performed in August 1987 in the region of Brazilian magnetic anomaly (L = 1.25). The launching time of the rocket was determined so that plasma injection was at the time when COSMOS 1809 satellite passed as close as possible to magnetic tube of injection. Caesium plasma jet was produced during not less than 300 s by an electric plasma generator separated from the payload. When the satellite passed the geomagnetic tube intersecting the injection region an enhancement of ELF emission at 140 Hz, 450 Hz by a factor of 2 was registered on board the satellite. An enhancement of energetic particle flux by a factor of 4-5 was registered on board the rocket. Observed ELF emission below 100 Hz is interpreted as the generation of oblique electromagnetic ion-cyclotron waves due to drift plasma instability at the front of the plasma jet.

  6. On the efficiency of ELF/VLF generation using HF heating of the auroral electrojet

    Papadopoulos, K.; Milikh, G.M.; Wallace, T.; McCarrick, M.; Yang, X.

    2003-01-01

    Using experimental measurements and theoretical analysis, it is shown that the HF/ELF conversion efficiency is controlled by the timescale for electron temperature saturation. This is a function of the ERP and frequency of the heater and the ionospheric electron density profile. For the current HAARP parameters, this corresponds to frequencies between 2 and 4 kHz. Efficiency optimization techniques as applied to the projected upgrading of the HAARP heater to its design power of 3.6 MW are discussed

  8. Rapporteur Report: Sources and Exposure Metrics for ELF Epidemiology (Part 1) (invited paper)

    Matthes, R.

    1999-01-01

    High quality epidemiological studies on the possible link between exposure to non-ionizing radiation and human health effects are of great importance for radiation protection in this area. The main sources of ELF fields are domestic appliances, different electrical energy distribution systems and all kinds of electrical machinery and devices at the workplace. In general, ELF fields present in the environment, show complex temporal patterns and spatial distributions, depending on the generating source. The complete characterisation of the different field sources often requires highly sophisticated instrumentation, and this is therefore not feasible within the scope of epidemiological studies. On average, individual exposure from ELF fields is low in both the working environment and in residential areas. Only at certain workplaces are people subject to significant ELF exposure with regard to biological effects. Different methods have been developed to determine levels of exposure received by study subjects, with the aim to rank exposed and non-exposed groups in epidemiological studies. These include spot measurements, calculations or modelling. The different methods used to estimate total exposure in epidemiological studies may result to a differing extent in a misclassification of the study subjects. Equally important for future studies is the selection of the appropriate exposure metric. The most widely used metric so far is the time-weighted average and thus represents a quasi standard metric for use in epidemiological studies. Beside, wire codes have been used for a long time in residential studies and job titles are often used in occupational studies. On the basis of the experience gained in previous studies, it would be desirable to develop standardised, state-of-the-art protocols to improve exposure assessment. New surrogates and metrics were proposed as the basis for further studies. But only few of these have recently undergone preliminary testing. A

    Full Text Available L'articolo si compone di due parti. Nella prima si espongono alcuni punti focali del dibattito sul rapporto tra glottodidattica e tecnologie digitali (dai dispositivi mobili ai software per la comunicazione, fino agli attuali socialnetwork. In particolare l’attenzione è rivolta sul fatto che la lingua della comunicazione digitale costituisce una varietà linguistica dal confronto con la quale l’insegnamento di una L2 non può ormai prescindere, e che le tecnologie digitali della comunicazione, se correttamente adottate fuori e dentro la classe, consentono di ridurre il confine tra apprendimento guidato e acquisizione spontanea di una lingua seconda. Filo conduttore della riflessione è il concetto di “competenza comunicativa digitale”, che si aggiunge alle componenti della competenza linguistico-comunicativa indicate dal Quadro Comune Europeo di Riferimento per le Lingue. Nella seconda parte del lavoro, dal taglio più didattico, si presenta una serie di strumenti e di esperienze di insegnamento/apprendimento della L2 con l’uso delle tecnologie digitali. In particolare ci si sofferma sulle opportunità offerte dal Web 2.0, simulando la creazione di una piattaforma per l’insegnamento/apprendimento dell’italiano L2 completamente online. Non si tratta di una semplice piattaforma per l’e-learning (o d-learning, ma di una vera e propria rete per l’insegnamento, l’apprendimento, la comunicazione e la formazione che trasforma il modo in cui si usa, si apprende e si insegna una L2. L2 on the Web.

    Parthasarathy, Shamesh Raj; Tukimin, Roha

    2018-01-01

    ELF EMF radiation have received considerable attention as a potential threat to the safety and health of people living in the vicinity of high voltage transmission lines, electric distribution substations, power stations and even in close proximity to electronics and electrical household appliances. The paper highlights the study on the ELF EMF safety assessment performed at residences comprising of an owner-occupied house, a completed vacant house and an under construction condominium. The objectives of this study were to determine the ELF EMF radiation exposure level from the high voltage transmission line, electric distribution substation, power station and electrical household appliances in the residences, and to assess the potential exposure received by the occupants at the assessed locations. The results were logged in the electric and magnetic field strength with the units of volt per meter (V/m) and miliGauss (mG) respectively. The instrument setup and measurement protocols during the assessment were adopted from standard measurement method and procedures stipulated under the Institute of Electrical and Electronics Engineers (IEEE) Standard. The results were compared with the standards recommended in the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines.

  14. Romulus’ adytum or asylum? A New Exegetical proposal for De lingua Latina 5, 8

    Federica Lazzerini

    2017-05-01

    Molto si è discusso sui quattro livelli progressivi secondo i quali Varrone struttura l’etimologia in ling. 5, 8; a ogni livello è associato un diverso tipo di analisi e si applica a una diversa categoria di parole. Una formulazione criptica ed ellittica, in un passo che nel manoscritto del testo è quasi certamente corrotto, avvolgono il quarto livello in una nube di incertezza e ambiguità. Se alcuni filologi hanno difeso il mantenimento del tradito Quartus, ubi est aditus et initia regis (“Il quarto livello è dove è l’ingresso e le origini del re”, la maggior parte delle interpretazioni moderne opta piuttosto per l’emendazione di aditus in adytum (“santuario” e legge il passo come un riferimento a vari tipi di culti misterici, collocando il quarto livello etimologico in un quadro di esoterismo. Nel presente contributo, si avanza la proposta che nel passo in questione non vi sia alcuna allusione ai misteri, ma un riferimento all’episodio storico-leggendario della fondazione, da parte di Romolo, di un “santuario” sul Campidoglio, destinato all’accoglienza di supplici provenienti da ogni popolo ed estrazione sociale. Questa istituzione portò alla formazione del primo nucleo abitativo di Roma e anche, di conseguenza, del sostrato vernacolare alle origini della lingua latina; come tale, tale episodio converge con gli interessi e le idee di Varrone. L’ipotesi che il quartus gradus etymologiae alluda al santuario di Romolo può essere difesa o dando una nuova interpretazione al termine adytum, o proponendo un’emendazione testuale (aditus > asylum, che produca il testo Quartus, ubi est asylum et initia regis.

    Full Text Available Victor Klemperers Tagebücher Ich will Zeugnis ablegen bis zum letzten: Tagebücher 1933-1945 haben nach ihrem Erscheinen Mitte der 1990er Jahre ein starkes Echo gefunden und gehören inzwischen zum Kanon der Tagebuchliteratur. Das zweibändige, während der nationalsozialistischen Diktatur entstandene Tagebuchwerk beschreibt die Lebenswelt eines deutsch-jüdischen Verfolgten im Dritten Reich. Der Antisemitismus zwang den Philologen zu einer Auseinandersetzung mit dem Relevanzverlust seiner Assimilationsbemühungen und seiner Kennzeichnung als Jude. Eine rekurrente Kompensationstaktik gegen seine erzwungene Randstellung besteht in der sprachkritischen Demontierung des Rassendenkens, um die Ungültigkeit des Antisemitismus nachzuweisen. Die Beobachtungen zur Lingua Tertii Imperii, die er in den Tagebuchblättern aufschrieb, wurden immer mehr zu seinem eigentlichen Werk. Das Tagebuch ist vor diesem Hintergrund in weiten Teilen zum Arbeitsjournal für die Sprachund Kulturanalysen Klemperers geworden. Der Interdependenz von Sprachkritik und Mentalitätsgeschichte in Klemperers Analyse der Sprache des Dritten Reiches gilt im vorliegenden Aufsatz das Hauptinteresse. Im ersten Teil wird der Frage nachgegangen, auf welche Art und Weise Victor Klemperer in seinen Notizen die Beziehung zwischen Sprache, Ideologie und Mentalität verstand. Im zweiten Teil wird unter Rückgriff auf Judith Butler und Louis Althusser in den Vordergrund gerückt, wie Victor Klemperer im Tagebuch vor Augen führt, dass das verletzende Sprechen gegen Juden im Nationalsozialismus eine subjektkonstituierende Wirkung hatte. Im letzten Teil des Aufsatzes gilt das Hauptaugenmerk der vom Tagebuchautor festgestellten diskursiven Einverleibung antisemitischer Rhetorik durch die verfolgte jüdische Bevölkerung.

  16. Influenze lunguistiche romanze nello sloveno letterario di Trieste. La lingua di Boris Pahor

    Mitja Skubic

    1984-12-01

    Full Text Available L'autore esamina la lingua dello scritto e t iestino Boris Pahor, urio de li eminenti creatori letterari in sloveno del secondo dopoguerra. Gli anni di scuola ed una  parte della giovinezza di Boris Pahor, nato nel 1913, appartengono ad un periodo nel quale lo sloveno a Trieste, e nelle province di Trieste       e di Gorizia, non godeva di uno  status pubblico ufficiale, salvo in chiesa. L influsso linguistico dell'italiano, normale in un territorio etnicamente e linguisticamente misto, spinto in una situazione anormale, creatasi nel primo  dopoguerra, non sorprende. Lo scrittore fu in  stretto contratto con l'italiano e il legame linguistico (e certo anche culturale è 'di doppia natura: esisstono, da una parte, influenze della parlata locale triestina -veneta, con qualche venatura tergestina, vale a dire friulana; dell'altra, lo scrittore ebbe a subire numerose influenze dell'italiano letterario. Non è facile scindere queste due fonti dei romanismi linguistici, che chiamiamo genericamente italianismi; il termine è fallace, perchè è fallace la grafia la quale rare volte palesa l'origine veneta: ščaveta, škojera, mandrijer, čožotska bragoca. L'interesse di questo contributo si concentra su prestiti, per lo più adattati al sistema fono-morfologico che vige per lo sloveno, e, soprattutto7 su calchi, quelli semantici e quelli sintattici. Una quantità non trascurabile di calchi ci convince della loro provenienza popolare, del fatto, cioe, che bisogna cer­ carne l'origine nel contatto linguistico diretto delle due etnie. Il materiale raccolto contraddice, dunaue. l'asserzione alquanto apodittica della provenienza popolare, immediata, dei soli presti­ ti e della provenienz letteraria, dotta, dei calchi. I calchi semantici sono parecchi: si tratta sempre dell'uso di un termine sloveno che in sloveno letterario e nei dialetti centrali esiste, ma che in Pahor viene usato con un significate sconosciuto allo sloveno centrale

  17. Global thunderstorm activity estimation based on number of transients in ELF-band

    Ondraskova, Adriena; Sevcik, Sebastian

    2017-04-01

    Schumann resonances (SR) are resonant electromagnetic oscillations in extremely low frequency band (ELF, 3 Hz - 3 kHz), which arise in the Earth-ionosphere cavity due to lightning activity in planetary range. The time records in the ELF-band consist of background signals and ELF transients/Q-bursts superimposed on the background exceeding it by a factor of 5 - 10. The former are produced by the common worldwide thunderstorm activity (100 - 150 events per second), the latter origin from individual intense distant lightning discharges (100 - 120 powerful strokes per hour). A Q-burst is produced by a combination of direct and antipodal pulses and the decisive factor for its shape follows from the source-to-observer distance. Diurnal/seasonal variations of global thunderstorm activity can be deduced from spectral amplitudes of SR modes. Here we focus on diurnal/seasonal variations of the number of ELF-transients assuming that it is another way of lightning activity estimation. To search for transients, our own code was applied to the SR vertical electric component measured in October 2004 - October 2008 at the Astronomical and Geophysical Observatory of FMPI CU, Slovakia. Criteria for the identification of the burst are chosen on the basis of the transient amplitudes and their morphological features. Monthly mean daily variations in number of transients showed that African focus dominates at 14 - 16 h UT and it is more active in comparison with Asian source, which dominates at 5 - 8 h UT in dependence on winter or summer month. American source had surprisingly slight response. Meteorological observations in South America aiming to determine lightning hotspots on the Earth indicate that flash rate in this region is greatest during nocturnal 0 h - 3 h local standard time. This fact may be interpreted that Asian and South American sources contribute together in the same UT. Cumulative spectral amplitude of the first three SR modes compared with number of ELF-transients in

    Telford, W. G.; Cox, W. G.; Stiner, D.; Singer, V. L.; Doty, S. B.

    BACKGROUND: The alkaline phosphatase (AP) substrate 2-(5'-chloro-2'-phosphoryloxyphenyl)-6-chloro-4-(3H)-quinazolinone (ELF((R))-97 for enzyme-labeled fluorescence) has been found useful for the histochemical detection of endogenous AP activity and AP-tagged proteins and oligonucleotide probes. In this study, we evaluated its effectiveness at detecting endogenous AP activity by flow cytometry. METHODS: The ELF-97 phosphatase substrate was used to detect endogenous AP activity in UMR-106 rat osteosarcoma cells and primary cultures of chick chondrocytes. Cells were labeled with the ELF-97 reagent and analyzed by flow cytometry using an argon ultraviolet (UV) laser. For comparison purposes, cells were also assayed for AP using a Fast Red Violet LB azo dye assay previously described for use in detecting AP activity by flow cytometry. RESULTS: The ELF-97 phosphatase substrate effectively detected endogenous AP activity in UMR-106 cells, with over 95% of the resulting fluorescent signal resulting from AP-specific activity (as determined by levamisole inhibition of AP activity). In contrast, less than 70% of the fluorescent signal from the Fast Red Violet LB (FRV) assay was AP-dependent, reflecting the high intrinsic fluorescence of the unreacted components. The ELF-97 phosphatase assay was also able to detect very low AP activity in chick chondrocytes that was undetectable by the azo dye method. CONCLUSIONS: The ELF-97 phosphatase assay was able to detect endogenous AP activity in fixed mammalian and avian cells by flow cytometry with superior sensitivity to previously described assays. This work also shows the applicability of ELF-97 to flow cytometry, supplementing its previously demonstrated histochemical applications. Copyright 1999 Wiley-Liss, Inc.

    Full Text Available Nel dare alle stampe la sua parodia dei Promessi Sposi (1930, Guido da Verona non immaginava di compiere delitto di lesa maestà nei confronti del totem manzoniano né che sarebbe stato oscurato dal controllo igienico fascista. Nel saggio si sostiene infatti, anche sulla base di evidenze ricavate dall'analisi del manoscritto, che la sua intenzione non fosse satirica, bensì ludico-parodica. Il cuore del saggio si incentra sull'analisi comparativa tra la versione daveroniana e l'ipotesto manzoniano, con particolare attenzione alle scaturigini del comico. Oltre che mettere in evidenza i tratti caratterizzanti la prosa di da Verona, captante e alluvionata di wits  linguistici, il saggio descrive le strategie comiche usate dall'autore, quelle basate sul carattere e sulle situazioni e quelle del discorso vero e proprio. Nel corso dell'analisi  si evidenzia come sia il comico del significante sia l'infrazione dei legami logici e di successione cooperino a incrinare la visione ordinata del mondo e della lingua strenuamente voluta e ottenuta da Alessandro Manzoni.   When the parody of Promessi Sposi (1930 was sent to press, Guido da Verona did not imagine he was committing the crime of lese-majesty with regard to the Manzonian totem, nor that it would be blacklisted by the Fascist regime. This paper shows that, based on the analysis of the manuscript, the author's intention was not satirical, but a playful parody. It is a comparative analysis between the da Verona version and the Manzonian hypertext, with particular attention placed on the origin of the comic. Besides highlighting the traits that characterize the text brimming with linguistic wit by da Verona, the paper describes the comedic strategies used by the author based on the characters and situations, as well as in the discourse itself. The analysis shows how the comic meaning and the breaking of logical and temporal links crack the orderly vision of the world and the language carefully

    2006-01-01

    Escape from TGF-β inhibition of proliferation is a hallmark of multiple cancers including lung cancer. We explored the role of ELF, crucial TGF-β adaptor protein identified from endodermal progenitor cells, in lung carcinogenesis and cell-cycle regulation. Interestingly, elf -/- mice develop multiple defects that include lung, liver, and cardiac abnormalities. Four out of 6 lung cancer and mesothelioma cell lines displayed deficiency of ELF expression with increased CDK4 expression. Immunohistochemistry and Western blot analysis of primary human lung cancers also showed decreased ELF expression and overexpression of CDK4. Moreover, rescue of ELF in ELF-deficient cell lines decreased the expression of CDK4 and resulted in accumulation of G1/S checkpoint arrested cells. These results suggest that disruption in TGF-β signaling mediated by loss of ELF in lung cancer leads to cell-cycle deregulation by modulating CDK4 and ELF highlights a key role of TGF-β adaptor protein in suppressing early lung cancer

    As a result of ischaemia/reperfusion, massive generation of reactive oxygen species occurs, followed by decreased activity of antioxidant enzymes. Extremely low frequency electromagnetic fields (ELF-EMF) can modulate oxidative stress, but there are no clinical antioxidant studies in brain stroke patients. The aim of our study was to investigate the effect of ELF-EMF on clinical and antioxidant status in post-stroke patients. Fifty-seven patients were divided into two groups: ELF-EMF and non-ELF-EMF. Both groups underwent the same 4-week rehabilitation program. Additionally, the ELF-EMF group was exposed to an ELF-EMF field of 40 Hz, 7 mT for 15 min/day for 4 weeks (5 days a week). The activity of catalase and superoxide dismutase was measured in hemolysates, and total antioxidant status (TAS) determined in plasma. Functional status was assessed before and after the series of treatments using Activities of Daily Living (ADL), Mini-Mental State Examination (MMSE), and Geriatric Depression Scale (GDS). Applied ELF-EMF significantly increased enzymatic antioxidant activity; however, TAS levels did not change in either group. Results show that ELF-EMF induced a significant improvement in functional (ADL) and mental (MMSE, GDS) status. Clinical parameters had positive correlation with the level of enzymatic antioxidant protection. Bioelectromagnetics. 38:386-396, 2017. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

  8. On the observations of unique low latitude whistler-triggered VLF/ELF emissions

    Altaf, M.; Singh, K. K.; Singh, A. K.; Lalmani

    A detailed analysis of the VLF/ELF wave data obtained during a whistler campaign under All India Coordinated Program of Ionosphere Thermosphere Studies (AICPITS) at our low latitude Indian ground station Jammu (geomag. lat. = 22° 26‧ N, L = 1.17) has yielded two types of unusual and unique whistler-triggered VLF/ELF emissions. These include (1) whistler-triggered hook emissions and (2) whistler-triggered long enduring discrete chorus riser emissions in VLF/ELF frequency range during night time. Such types of whistler-triggered emissions have not been reported earlier from any of the ground observations at low latitudes. In the present study, the observed characteristics of these emissions are described and interpreted. Dispersion analysis of these emissions show that the whistlers as well as emissions have propagated along a higher geomagnetic field line path with L-values lying ∼L = 4, suggesting that these triggered emissions are to be regarded as mid-latitude emissions. These waves could have propagated along the geomagnetic field lines either in a ducted mode or in a pro-longitudinal (PL) mode. The measured intensity of the triggered emissions is almost equal to that of the source waves and does not vary throughout the period of observation on that day. It is speculated that these emissions may have been generated through a process of resonant interaction of the whistler waves with energetic electrons. Parameters related to this interaction are computed for different values of L and wave amplitude. The proposed mechanism explains some aspects of the dynamic spectra.

  9. Extremely Low Frequency-Magnetic Fields (ELF-EMF) occupational exposure and natural killer activity in peripheral blood lymphocytes

    Gobba, Fabriziomaria; Bargellini, Annalisa; Scaringi, Meri; Bravo, Giulia; Borella, Paola

    2009-01-01

    Extremely Low Frequency-Magnetic Fields (ELF-MF) are possible carcinogens to humans and some data suggest that they can act as promoters or progressors. Since NK cells play a major role in the control of cancer development, an adverse effect on ELF-MF on NK function has been hypothesized. We examined NK activity in 52 workers exposed to different levels of ELF-MF in various activities. Individual exposure was monitored during 3 complete work-shifts using personal dosimeters. Environmental exposure was also monitored. ELF-MF levels in the workers were expressed as Time-Weighted Average (TWA) values. NK activity was measured in peripheral blood lymphocytes (PBL). In the whole group the median occupational TWA was 0.21 μT. According to the TWA levels, workers were classified as low exposed (26 subjects, TWA ≤ 0.2 μT) and higher exposed workers (26 subjects; TWA > 0.2 μT). In higher exposed workers, we observed a trend to reduce NK activity compared to low exposed, but the difference was not significant. Then we selected a subgroup of highest exposed workers (12 subjects; TWA > 1 μT); no difference was observed between low and highest exposed subjects in the main personal variables. Considering both E:T ratios from 12:1 to 50:1 and Lytic Units, a significant reduction in NK activity was observed in the highest exposed workers compared to the low exposed. Multivariate analysis showed a significant negative correlation between exposure and LU, while no correlation was evidenced with other personal characteristics. ELF-MF are considered possible carcinogens, and existing data suggest that they can act as promoters. Due to the role of NK activity in host defence against cancer, the results obtained in this study in workers exposed to ELF-MF levels exceeding 1 μT are in agreement with this hypothesis, and support the need for further investigation in this field

    2010-02-01

    Full Text Available As the total amount of data measured by scientific spacecraft is drastically increasing, it is necessary for researchers to develop new computation methods for efficient analysis of these enormous datasets. In the present study, we propose a new algorithm for similar data retrieval. We first discuss key descriptors that represent characteristics of the VLF/ELF waves observed by the Akebono spacecraft. Second, an algorithm for similar data retrieval is introduced. Finally, we demonstrate that the developed algorithm works well for the retrieval of the VLF spectrum with a small amount of CPU load.

    The propagation characteristic of ELF (10 Hz - 1500 Hz) electromagnetic waves observed on ARCAD 3, in three different zones: low L value (L 6). Unambiguous determinations of the wave normal directions are obtained from the interpretations of the measurements of four (3 magnetic, 1 electric) wave field components. The technique that is used, is based on the Means method in the cases of highly polarized waves and on the Storey and Lefeuvre WDF method in the other cases. A particular emphasis is put on the propagation characteristics of the waves, in a multiple ion plasma, and on the cut-off frequencies which appear at and below the local proton gyrofrequency

  13. O-GlcNAc inhibits interaction between Sp1 and Elf-1 transcription factors

    Lim, Kihong; Chang, Hyo-Ihl

    2009-01-01

    The novel protein modification, O-linked N-acetylglucosamine (O-GlcNAc), plays an important role in various aspects of cell regulation. Although most of nuclear transcription regulatory factors are modified by O-GlcNAc, O-GlcNAc effects on transcription remain largely undefined yet. In this study, we show that O-GlcNAc inhibits a physical interaction between Sp1 and Elf-1 transcription factors, and negatively regulates transcription of placenta and embryonic expression oncofetal protein gene (Pem). These findings suggest that O-GlcNAc inhibits Sp1-mediated gene transcription possibly by interrupting Sp1 interaction with its cooperative factor.

  14. ELF - An experimental programme to quantify the effects of load follow and perturbated power histories

    Bairiot, H.; Hass, D.; Stora, J.P.

    1984-01-01

    Most of the ramp tests performed in national or international programmes have as main objective to define the fuel rod failure/survival limits, as a function of various parameters. Only a few of these experiments are sufficiently instrumented. The main feature of the ELF programme, described in this paper, consists in continuously measuring the cladding diameter during irradiation in OSIRIS of pre-irradiated PWR fuel rods, in order to provide strain relaxation data under various operating conditions. Power fluctuations during these OSIRIS irradiations are defined in order to obtain the conditioning and deconditioning kinetics of the fuel rods. (author)

    ELFE is a project to develop a 15 to 30 GeV, high luminosity, continuous beam electron accelerator for scattering experiments from fixed nuclear targets. The goal is to explore the quark and gluon structure of matter by exclusive and semi-exclusive electron scattering from nuclei. The idea of integrating ELFE into TESLA facility is based on the fact that the superconducting linac is operated at a low duty cycle, about 0.4%, for the electron-positron collider mode and the machine is available for other tasks during the time between collider pulses. A fraction of the beam pulses produced by TESLA could be injected into the HERA ring until the ring is filled. The authors show that it is possible to extract the electrons from HERA used as a stretcher ring and produce a high luminosity quasi continuous beam suitable for nuclear physics experiments. The performances of the extracted beam in term of emittance, energy spread and duty factor have been evaluated. (N.T.).

    2008-01-01

    Full Text Available Young children with multiple disabilities (e.g., both cognitive and motor disabilities are confronted with severe limitations in language development from birth and later on. Stimulating the adult-child communication can decrease these limitations. Within LinguaBytes, a three-year research program, we try to stimulate language development by developing an interactive and adaptive play and learning environment, incorporating tangible objects and multimedia content, based on interactive storytelling and anchored instruction. The development of a product for such a heterogeneous user group presents substantial challenges. We use a Research-through-Design method, that is, an iterative process of developing subsequent experiential prototypes and then testing them in real-life settings, for example, a center for rehabilitation medicine. This article gives an outline of the development of the LinguaBytes play and learning environment from the earliest studies up to the current prototype, CLICK-IT.

  19. Effects of extremely low frequency electromagnetic field (ELF-EMF) on catalase, cytochrome P450 and nitric oxide synthase in erythro-leukemic cells.

    Patruno, Antonia; Tabrez, Shams; Pesce, Mirko; Shakil, Shazi; Kamal, Mohammad A; Reale, Marcella

    2015-01-15

    Extremely low frequency electromagnetic fields (ELF-EMFs) are widely employed in electrical appliances and different equipment such as television sets, mobile phones, computers and microwaves. The molecular mechanism through which ELF-EMFs can influence cellular behavior is still unclear. A hypothesis is that ELF-EMFs could interfere with chemical reactions involving free radical production. Under physiologic conditions, cells maintain redox balance through production of ROS/RNS and antioxidant molecules. The altered balance between ROS generation and elimination plays a critical role in a variety of pathologic conditions including neurodegenerative diseases, aging and cancer. Actually, there is a disagreement as to whether there is a causal or coincidental relationship between ELF-EMF exposure and leukemia development. Increased ROS levels have been observed in several hematopoietic malignancies including acute and chronic myeloid leukemias. In our study, the effect of ELF-EMF exposure on catalase, cytochrome P450 and inducible nitric oxide synthase activity and their expression by Western blot analysis in myelogenous leukemia cell line K562 was evaluated. A significant modulation of iNOS, CAT and Cyt P450 protein expression was recorded as a result of ELF-EMF exposure in both phorbol 12-myristate 13-acetate (PMA)-stimulated and non-stimulated cell lines. Modulation in kinetic parameters of CAT, CYP-450 and iNOS enzymes in response to ELF-EMF indicates an interaction between the ELF-EMF and the enzymological system. These new insights might be important in establishing a mechanistic framework at the molecular level within which the possible effects of ELF-EMF on health can be understood.

  20. Evaluation of the chromium contamination at Ribeirão dos Bagres, Franca (SP), Brazil, by the 210Pb method

    Matamet, F.R.M.; Bonotto, D.M.

    2013-01-01

    This paper presents a chronological study focusing the use of 210 Pb in four sediment cores collected at Ribeirão dos Bagres in the region of Franca, São Paulo State, Brazil. When evaluating the sedimentation rate by using the 210 Pb method, it was possible to monitor historical changes occurring in the concentrations of chromium present in the sediments. In order to do so, several specific parameters were determined in sediments, as chromium concentration, major oxides, organic matter, grain size, and chemical and physical–chemical parameters of waters. The sediments possessed a Cr concentration range of 0.83–26.25 mg/kg that is below the world's average of shales. The sedimentation rates obtained from the 210 Pb analysis were between 0.07 and 0.77 g cm −2 year −1 , while the linear sedimentation rate was from 0.6 to 3.2 cm/year. The adoption of the CIC (Constant Initial Concentration) 210 Pb model allowed characterize older sediments, aged 177 years, and younger sediments, aged 4 years. The organic matter in the sediments was more abundant in the first few centimeters of practically all profiles, and the analysis of oxides showed that silica is the major constituent of the sediments, in which there is predominance of sand and silt. In addition, the analysis of the physical and chemical parameters of waters indicated that they are suitable for navigation and natural harmony landscape. - Highlights: • Application of natural radionuclides in an important industrial center devoted to the production of leather for manufacturing shoes. • Study of a well-known site of environmental Cr contamination. • Use of the Pb-210 chronological CIC model to provide an approach of the historical Cr contamination in the region

  1. ELF wave generation in the ionosphere using pulse modulated HF heating: initial tests of a technique for increasing ELF wave generation efficiency

    R. Barr

    1999-06-01

    Full Text Available This paper describes the results of a preliminary study to determine the effective heating and cooling time constants of ionospheric currents in a simulated modulated HF heating, `beam painting' configuration. It has been found that even and odd harmonics of the fundamental ELF wave used to amplitude modulate the HF heater are sourced from different regions of the ionosphere which support significantly different heating and cooling time constants. The fundamental frequency and its odd harmonics are sourced in a region of the ionosphere where the heating and cooling time constants are about equal. The even harmonics on the other hand are sourced from regions of the ionosphere characterised by ratios of cooling to heating time constant greater than ten. It is thought that the even harmonics are sourced in the lower ionosphere (around 65 km where the currents are much smaller than at the higher altitudes around 78 km where the currents at the fundamental frequency and odd harmonics maximise.Key words.

  2. The peculiarities of power terrestrial ELF emission in the Earth's ionosphere

    Korepanov, Valery; Dudkin, Fedir; Pronenko, Vira; Chvach, Valery

    2016-04-01

    The near-Earth space is saturated with electromagnetic (EM) waves of terrestrial origin in a wide frequency range. The most powerful natural sources of EM emission are thunderstorms and triggered by them Schumann resonance (SR) radiation which is the narrowband EM noise that occurs due to the global thunderstorm activity in the Earth-ionosphere cavity in frequency range about 7-100 Hz. The considerable part of the terrestrial EM emission belongs to everyday human activity which increases year by year with unpredictable consequences. At the beginning of space exploration era it was considered that high frequency EM waves freely penetrate through the Earth's ionosphere, but the terrestrial EM emission below very low frequency range is limited by ionospheric F2 layer boundary due to great EM losses in plasma. About 40 years ago the power lines harmonic radiation (multiple of 50/60 Hz) was found at satellite observations in a few kilohertz range, nevertheless the ionosphere was considered fully opaque for extremely low frequency (ELF) EM emission. However recently, in spite of theoretical estimations, the SR harmonics and power line emission (PLE) 50/60 Hz were discovered during flights of low Earth orbiting satellites C/NOFS (Simões et al., 2011) and Chibis-M (Dudkin et al., 2015) at heights 400-800 km, i.e. over F2-layer. Last results are a great challenge to the theory of ELF EM emission propagation in the Earth's ionosphere as well as for study of long-term influence of constantly increasing electric energy consumption by human civilization in the Earth's environment. We present the analysis of the space and time distribution for observed PLE and SR harmonics, their connection with power terrestrial sources of ELF emission and possible relation between measured values and ionosphere conditions. Also some electromagnetic parameters have been estimated. Simões, F. A., R. F. Pfaff, and H. T. Freudenreich (2011), Satellite observations of Schumann resonances in the

    Thirty for (34) published studies, conducted from 1994 to the present to evaluate the genotoxic effect of magnetic fields using ELF-EMF and diagnostic resonance on humans by the micronucleus assay have been reviewed. some characteristics of the assay methods, their significance to genotoxicity and basic interpretations of the results of these assays are discussed. of the studies analysed 70.5% implicated genotoxic effects induced by these magnetic fields: 52.9% were due to exposure to magnetic fields only and 17,6% by exposure to magnetic fields in combination with some treatment types, resulting in additive or synergistic effect. Evidence exist to support the notion that exposure of humans to magnetic fields stimulates genotoxic effects, although the actual mechanisms of action or even the true human health consequences resulting from these exposure still remain unclear.

    Full Text Available Zwei 'jahrhunderthochwasser' in elf jahren - ein vergleich der hochwasserereignisse von 2002 und 2013 (in Deutschland. Worldwide floods are among the most frequent and most momentous natural disasters. They occur in unpredictable intervals and dimensions and always bring particularly devastating or catastrophic impacts, if they get into contact with people or its uses. Within eleven years only Germany was affected of two so-called 'century-floods'. The expiry of extreme high water can be influenced by technical measures only up to a certain degree. It is therefore necessary to have a high protection from the effects of floods and to keep the impact as low as possible. Both being prepared as well as possible and being capable of acting for the case of emergency are corequisite. Flood protection is a longsome and s steadily continuing process. In dealing with the consequences of floods both political measures and the commitment and solidarity of the citizens were in demand.

  6. Background ELF magnetic fields in incubators: a factor of importance in cell culture work.

    Mild, Kjell Hansson; Wilén, Jonna; Mattsson, Mats-Olof; Simko, Myrtill

    2009-07-01

    Extremely low frequency (ELF) magnetic fields in cell culture incubators have been measured. Values of the order of tens of muT were found which is in sharp contrast to the values found in our normal environment (0.05-0.1microT). There are numerous examples of biological effects found after exposure to MF at these levels, such as changes in gene expression, blocked cell differentiation, inhibition of the effect of tamoxifen, effects on chick embryo development, etc. We therefore recommend that people working with cell culture incubators check for the background magnetic field and take this into account in performing their experiments, since this could be an unrecognised factor of importance contributing to the variability in the results from work with cell cultures.

  7. Synchronization control of Hodgkin-Huxley neurons exposed to ELF electric field

    Che Yanqiu; Wang Jiang; Zhou Sisi; Deng Bin

    2009-01-01

    This paper presents an adaptive neural network H ∞ control for unidirectional synchronization of modified Hodgkin-Huxley (HH) neurons exposed to extremely low frequency (ELF) electric field. The proposed modified HH neurons exhibit periodic and chaotic dynamics in response to sinusoidal electric field stimulation. Based on the Lyapunov stability theory, we derive the updated laws of neural network for approximating the nonlinear uncertain functions of the error dynamical system. The H ∞ design technique makes the controller robust to unmodeled dynamics, disturbances and approximate errors. The proposed controller not only ensures closed-loop stability, but also guarantees an H ∞ performance for the synchronization error system. The states of the controlled slave system exponentially synchronize with that of the master one after control. The simulation results demonstrate the validity of the proposed method.

  8. On precursory ULF/ELF electromagnetic signatures for the Kobe earthquake on April 12, 2013

    Schekotov, A.; Izutsu, J.; Hayakawa, M.

    2015-12-01

    After the 2011 Tohoku earthquake (EQ), there have been numerous aftershocks in the eastern and Pacific Ocean of Japan, but EQs are still rare in the western part of Japan. In this situation a relatively large (magnitude (M) ∼ 6) EQ happened on April 12 (UT), 2013 at a place close to the 1995 Kobe EQ (M ∼ 7), so we have tried to find whether there existed any electromagnetic precursors to this EQ. Two precursory signatures are detected: one is the depression of ULF (ultra-low-frequency, 0.01-0.02 Hz) geomagnetic variations on April 9, and the second is wideband ELF (extremely low frequency) electromagnetic radiation on April 11. These results for the 2013 Kobe EQ are compared with the corresponding results for the former 1995 Kobe EQ.

  10. Investigations of Relatively Easy To Construct Antennas With Efficiency in Receiving Schumann Resonances: Preparations for a Miniaturized Reconfigurable ELF Receiver

    Farmer, Brian W.; Hannan, Robert C.

    2003-01-01

    Relatively little is known about the cavity between the Earth and the ionosphere, which opens opportunities for technological advances and unique ideas. One effective means to study this cavity is with extremely low frequency (ELF) antennas. Possible applications of these antennas are global weather prediction, earthquake prediction, planetary exploration, communication, wireless transmission of power, or even a free energy source. The superconducting quantum interference device SQUID) and the coil antenna are the two most acceptable receivers discovered for picking up ELF magnetic fields. Both antennas have the potential for size reduction, allowing them to be portable enough for access to space and even for personal ware. With improvements of these antennas and signal processing, insightful analysis of Schumann resonance (SR) can give the science community a band of radio frequency (RF) signals for improving life here on Earth and exploring beyond.

    Plant steroid hormones, brassinosteroids (BRs), are of great importance for plant growth and development. BRs signal through a cell surface receptor kinase, BRI1, and a GSK3-like kinase, BIN2, to regulate the BES1/BZR1 family of transcription factors, which directly bind to target gene promoters to activate or repress gene expression and mediate BR responses. To understand how BES1 regulates target gene expression, we identified two BES1-interacting proteins, ELF6 (early flowering 6) and its ...

    2006-01-01

    The Greek Atomic Energy Commission (E.E.A.E.) is the competent national authority for the protection of the general public and the environment from artificially produced non-ionizing radiation. To this end, E.E.A.E. carries out measurements in the vicinity of all kinds of facilities emitting E.L.F. electric and magnetic fields (e.g. power lines, high voltage substations) and RF electromagnetic fields (e.g. audio, radio and television antennas, mobile phone base stations, radar and satellite earth stations and other microwave communication systems), in order to monitor whether the general public exposure limits are being adhered to. Regarding the electromagnetic fields emitted by antenna stations, the safety limits in Greek legislation were recently set to 70% of the I.C.N.I.R.P. values and to 60% of them if the antenna station is closer than 300 m from the perimeter of day nurseries, schools, hospitals or elder-care facilities, while in the case of extremely low frequency fields, the limit values are set exactly the same as the reference levels in I.C.N.I.R.P. guidelines. Regarding the levels of E.L.F. electric and magnetic fields in Greece E.E.A.E. has conducted many measurements around the elements of the electric grid where the main interest of the public is focused. Theoretical estimations and typical values based on actual measurements of the fields in the vicinity of the power lines used in Greece are presented. Measurement results in the vicinity of substations are also presented. In general, the levels of the magnetic field in the vicinity of the power grid elements are well below the established safety limits; whereas the levels of the electric field may reach values comparable to the safety limits very close to extremely high voltage lines. However, there is no case where the measured values of elf electric or magnetic fields were higher than the safety limits. There are a few exceptional cases where measurements of RF fields conducted by E.E.A.E. in the

Regarding the levels of E.L.F. electric and magnetic fields in Greece E.E.A.E. has conducted many measurements around the elements of the electric grid where the main interest of the public is focused. Theoretical estimations and typical values based on actual measurements of the fields in the vicinity of the power lines used in Greece are presented. Measurement results in the vicinity of substations are also presented. In general, the levels of the magnetic field in the vicinity of the power grid elements are well below the established safety limits; whereas the levels of the electric field may reach values comparable to the safety limits very close to extremely high voltage lines. However, there is no case where the measured values of elf electric or magnetic fields were higher than the safety limits. There are a few exceptional cases where measurements of RF fields conducted by E.E.A.E. in the

    Full Text Available This article aims to demonstrate how, in the context of the restructuring process, under way since the early 1990’s, business strategies, guided by building corporation networks inside and outside the chain of production and the establishment of a system of shared governance between the links of that same chain, resulted in a dynamic, economic and social development significantly more robust in the productive territory where they were tried. For the discussion of this problem, it is relied on the study of the two major poles of shoes manufacturing in the State of São Paulo: Franca, specialized in men’s footwear, and Birigui, specialized in children’s shoes.

  7. A simplified theory of ELF propagation in the Earth-ionosphere transmission line

    Booker, H.G.

    1980-01-01

    An approximate theory of ELF propagation in the Earth-ionosphere transmission line is developed by combining the reflection theory of Booker and Lefeuvre with Greifinger and Greifinger's treatment of the effect of ionization below the level of reflection. The theory allows for the influence of the Earth's magnetic field, for reflection from the gradient on the under side of the D-region (or, at night, of a ledge below the E-region), for reflection from the gradient on the underside of the E-region and for reflection from the gradient on the topside of the E-region. The procedure is to compare local vertical gradient with local wavelength, thereby classifying altitude into intervals where the gradient is high and ones where it is low. Where the gradient is low, the phase-integral treatment is adequate. An interval where the gradient is high may, to a first approximation, be replaced by a discontinuity. The amount of the discontinuity is the difference between the refractive indices at the top and bottom of the interval of high gradient, judged in relation to local wavelength. It is then a matter of combining reflections from the several discontinuities. This requires calculation of the complex phase-changes between the discontinuities. But there are the intervals where the phase-integral treatment is available. To a better approximation, there is a non-zero phase change associated with an interval of high gradient. The method for incorporating this is described. (author)

    Baroncelli, P; Battisti, S; Checcucci, A; Comba, P; Grandolfo, M; Serio, A; Vecchia, P

    1986-01-01

    This is a cross-sectional survey on the health conditions of railways workers active in 258 interconnection and conversion substations all over Italy. Measurements performed in both kinds of substations operating at 220 kV have shown that maximum levels of the electric field strength and of the magnetic flux density at 50 Hz are of the order of 5 kV/m and 15 microT, respectively. Three subject groups, differently exposed (1, 10, 20 h/week), and an unexposed control group, for a total number of 627 workers, constitute the population at study. All subjects underwent a general medical examination, laboratory investigations, and a series of selected examinations relative to three systems (nervous, cardiovascular, and haematopoietic) considered at higher risk. No differences have been found between the exposed and the control groups. It is concluded that workers exposed to ELF electromagnetic fields of moderate strength do not show the presence of clear effects on their state of health.

    Buettner, H. M.; Burker, G. J.; Didwall, E. M.; Holladay, G.; Lytle, R. J.

    1985-08-01

    We use computer models and experiments to explore the feasibility of communication between points underground and on the Earth's surface. Emphasis is placed on ELF-VLF electromagnetic propagation through the Earth; nominally, we investigated propagation in the 200 Hz-30 kHz frequency range. The computer modeling included calculations of the fields of a point electric or magnetic source in a homogeneous half space or a stratified earth. Initial results for an insulated antenna of finite length are also considered. The experiments involved through-the-Earth transmissions at two locations in Pennsylvania, both of which had large formations of limestone. Initial results indicate that information rates as high as kbits/s may be possible for subsurface depths of 300 m or less. Accuracy of these estimates depends on the electromagnetic propagation constant of the rock, the noise characteristics, and the modulation scheme. Although a nuisance for evaluating through-the-Earth propagation, the existence of subsurface metal conductors can improve the transmission character of the site.

    Full Text Available Abstract Backgound The effects of extremely low-frequency electromagnetic fields (ELF-EMF on the blood serum and liver lipid concentrations of male Wistar rats were assessed. Methods Animals were exposed to a single stimulation (2 h of ELF-EMF (60 Hz, 2.4 mT or sham-stimulated and thereafter sacrificed at different times (24, 48 or 96 h after beginning the exposure. Results Blood lipids showed, at 48 h stimulated animals, a significant increase of cholesterol associated to high density lipoproteins (HDL-C than those observed at any other studied time. Free fatty acid serum presented at 24 h significant increases in comparison with control group. The other serum lipids, triacylglycerols and total cholesterol did not show differences between groups, at any time evaluated. No statistical differences were shown on total lipids of the liver but total cholesterol was elevated at 24 h with a significant decrease at 96 h (p = 0.026. The ELF-EMF stimulation increased the liver content of lipoperoxides at 24 h. Conclusion Single exposures to ELF-EMF increases the serum values of HDL-C, the liver content of lipoperoxides and decreases total cholesterol of the liver. The mechanisms for the effects of ELF-EMF on lipid metabolism are not well understand yet, but could be associated to the nitric oxide synthase EMF-stimulation.

  12. Properties of ELF electromagnetic waves in and above the earth's ionosphere deduced from plasma wave experiments on the OV1-17 and Ogo 6 satellites

    Kelley, M.C.; Tsurutani, B.T.; Mozer, F.S.

    1975-01-01

    An analysis of ac electric field data obtained on board the OV1-17 satellite and ac magnetic field data obtained on board the Ogo 6 satellite has been made during the northern hemisphere spring and summer of 1969 with the purpose of studying extreme low frequency (ELF) electromagnetic waves above the earth's ionosphere. The results are in basic agreement with a number of previous ground-based and low-altitude satellite experiments in that the peak signal was observed at high latitudes outside the statistical location of the plasmapause on the day side of the earth, that ELF chorus was very often observed in conjunction with the steady ELF hiss emissions, that the winter hemisphere signal was considerably smaller than that observed in summer or in equinoctial months, and that the emission strength and region of occurrence are asymmetric about magnetic noon. Observations of such strong hiss signals outside the plasmasphere are somewhat surprising in light of Ogo 3 and Ogo 5 measurements which show steady ELF hiss to be closely confined to the plasmasphere at high altitudes during normal circumstances. The present study supports the hypothesis that hiss leaks out of the plasmasphere and refracts downward into the lower ionosphere; such a model predicts the observed summer-winter asymmetry and the poleward skewing of the ELF peak signal strength with decreasing altitude

    The objective of this research work was to evaluate Klucel™ hydroxypropylcellulose (HPC) EF and ELF polymers, for solubility enhancement as well as to address some of the disadvantages associated with solid dispersions. Ketoprofen (KPR), a Biopharmaceutics Classification System class II drug with poor solubility, was utilized as a model compound. Preliminary thermal studies were performed to confirm formation of a solid solution/dispersion of KPR in HPC matrix and also to establish processing conditions for hot-melt extrusion. Extrudates pelletized and filled into capsules exhibited a carrier-dependent release with ELF polymer exhibiting a faster release. Tablets compressed from milled extrudates exhibited rapid release owing to the increased surface area of the milled extrudate. Addition of mannitol (MNT) further enhanced the release by forming micro-pores and increasing the porosity of the extrudates. An optimized tablet formulation constituting KPR, MNT, and ELF in a 1:1:1 ratio exhibited 90% release in 15 min similar to a commercial capsule formulation. HPC polymers are non-ionic hydrophilic polymers that undergo polymer-chain-length-dependent solubilization and can be used to enhance solubility or dissolution rate of poorly soluble drugs. Dissolution/release rate could be tailored for rapid-release applications by selecting a suitable HPC polymer and altering the final dosage form. The release obtained from pellets was carrier-dependent and not drug-dependent, and hence, such a system can be effectively utilized to address solubility or precipitation issues with poorly soluble drugs in the gastrointestinal environment.

  18. Inhibition of Salmonella typhi growth using extremely low frequency electromagnetic (ELF-EM) waves at resonance frequency.

    2014-08-01

    Typhoid is a serious disease difficult to be treated with conventional drugs. The aim of this study was to demonstrate a new method for the control of Salmonella typhi growth, through the interference with the bioelectric signals generated from the microbe during cell division by extremely low frequency electromagnetic waves (ELF-EMW-ELF-EM) at resonance frequency. Isolated Salmonella typhi was subjected to square amplitude modulated waves (QAMW) with different modulation frequencies from two generators with constant carrier frequency of 10 MHz, amplitude of 10 Vpp, modulating depth ± 2 Vpp and constant field strength of 200 V m(-1) at 37°C. Both the control and exposed samples were incubated at the same conditions during the experiment. The results showed that there was highly significant inhibition effect for Salm. typhi exposed to 0·8 Hz QAMW for a single exposure for 75 min. Dielectric relaxation, TEM and DNA results indicated highly significant changes in the molecular structure of the DNA and cellular membrane resulting from the exposure to the inhibiting EM waves. It was concluded that finding out the inhibiting resonance frequency of ELF-EM waves that deteriorates Salm. typhi growth will be promising method for the treatment of Salm. typhi infection either in vivo or in vitro. This new non-invasive technique for treatment of bacterial infections is of considerable interest for the use in medical and biotechnological applications. © 2014 The Society for Applied Microbiology.

Da questo punto di vista appare urgente una riflessione approfondita che vada a toccare i valori espressi dalla multiculturalità, se non altro per com-prendere meglio il contesto locale nel quale viviamo. Allo scopo vogliamo partire proprio da lontano nel tempo e partiamo dal concetto di mito e dalle narrazioni in esso contenute.A nostro avviso i concetti espressi dal mito si prestano molto bene per la costruzione di un percorso che questo lavoro vuole sviluppare e che toccherà da vicino alcune riflessioni sulla lingua italiana, sulla storia e sulla geografia.

From this point of view, an in-depth reflection seems urgent which hits the values expressed by many cultures, even if only to better understand the local context we live in, and the necessary changes for a new structure intercultural learning. With this intent, we want to start from far away in time and we start from the concept of myth and the narratives contained in it.

  3. Assessing occupational and domestic ELF magnetic field exposure in the UK Adult Brain Tumour Study: Results of a feasibility study

    Van Tongeren, M.; Mee, T.; Whatmough, P.; Broad, L.; Mashlanyj, M.; Allen, S.; Muir, K.; McKinney, P.

    2004-01-01

    The feasibility of measuring exposure to extremely low frequency magnetic fields (ELF MF) in the UK Adult Brain Tumour Study (UKABTS) was examined. During the study, 81 individuals and 30 companies were approached with 79 individuals and 25 companies agreeing to participate. Exposure data were collected using EMDEX II dosemeters worn by the participants for 3-4 consecutive days. Data were collected over a total of 321 d, including non-occupational periods. The results showed occupational exposure to be the main determinant of overall exposure. Moderate to strong correlations were found between arithmetic mean exposure and all other metrics with the possible exception of maximum exposure. Significant differences in exposure were found between job categories with large variability in certain categories. Highest average exposures were found for security officers (arithmetic mean, AM: 0.78 μT), secretaries (AM: 0.48 μT) and dentists (AM: 0.42 μT). Welding and working near high-voltage power lines were associated with elevated exposure. In summary, acceptably precise measures of ELF MF exposure are feasible at relatively moderate cost. The results were used to develop a protocol for data collection from subjects in the UKABTS. (authors)

  4. Indoor transformer stations and ELF magnetic field exposure: use of transformer structural characteristics to improve exposure assessment.

    Okokon, Enembe Oku; Roivainen, Päivi; Kheifets, Leeka; Mezei, Gabor; Juutilainen, Jukka

    2014-01-01

    Previous studies have shown that populations of multiapartment buildings with indoor transformer stations may serve as a basis for improved epidemiological studies on the relationship between childhood leukaemia and extremely-low-frequency (ELF) magnetic fields (MFs). This study investigated whether classification based on structural characteristics of the transformer stations would improve ELF MF exposure assessment. The data included MF measurements in apartments directly above transformer stations ("exposed" apartments) in 30 buildings in Finland, and reference apartments in the same buildings. Transformer structural characteristics (type and location of low-voltage conductors) were used to classify exposed apartments into high-exposure (HE) and intermediate-exposure (IE) categories. An exposure gradient was observed: both the time-average MF and time above a threshold (0.4 μT) were highest in the HE apartments and lowest in the reference apartments, showing a statistically significant trend. The differences between HE and IE apartments, however, were not statistically significant. A simulation exercise showed that the three-category classification did not perform better than a two-category classification (exposed and reference apartments) in detecting the existence of an increased risk. However, data on the structural characteristics of transformers is potentially useful for evaluating exposure-response relationship.

  6. Exposure of ELF-EMF and RF-EMF Increase the Rate of Glucose Transport and TCA Cycle in Budding Yeast.

    Lin, Kang-Wei; Yang, Chuan-Jun; Lian, Hui-Yong; Cai, Peng

    2016-01-01

    In this study, we investigated the transcriptional response to 50 Hz extremely low frequency electromagnetic field (ELF-EMF) and 2.0 GHz radio frequency electromagnetic field (RF-EMF) exposure by Illumina sequencing technology using budding yeast as the model organism. The transcription levels of 28 genes were upregulated and those of four genes were downregulated under ELF-EMF exposure, while the transcription levels of 29 genes were upregulated and those of 24 genes were downregulated under RF-EMF exposure. After validation by reverse transcription quantitative polymerase chain reaction (RT-qPCR), a concordant direction of change both in differential gene expression (DGE) and RT-qPCR was demonstrated for nine genes under ELF-EMF exposure and for 10 genes under RF-EMF exposure. The RT-qPCR results revealed that ELF-EMF and RF-EMF exposure can upregulate the expression of genes involved in glucose transportation and the tricarboxylic acid (TCA) cycle, but not the glycolysis pathway. Energy metabolism is closely related with the cell response to environmental stress including EMF exposure. Our findings may throw light on the mechanism underlying the biological effects of EMF.

    Full Text Available La modalità plurilingue della comunicazione in classi di lingua straniera può rientrare tra le strategie pedagogiche a disposizione dell’insegnante per il raggiungimento di precisi scopi didattici e formativi. Partendo da una breve analisi sul significato di parlante plurilingue e plurilinguismo stesso, in questo articolo si è voluto esaminare come si attua una educazione al plurilinguismo in contesti formativi e, in particolare, se e come l’utilizzo della L1 può costituire uno strumento di supporto all’insegnamento e all’apprendimento di una lingua straniera. A questo scopo sono stati analizzati i dati raccolti presso l’Università di Coventry durante corsi di italiano L2 per studenti anglofoni. I fenomeni di contatto linguistico L1/L2 più frequenti e significativi sono stati suddivisi in base al parlante e alle loro funzioni.   The phenomena of l1/l2 alternation in the teaching of italian as a foreign language. analysis of a corpus of didactic interactions Multilingual communication in foreign language classrooms can be considered as one of the teacher’s pedagogical  strategies to achieve specific educational aims. Through a brief analysis of the meaning of multilingual speakers and multilingualism, this article examines how an education to multilingualism in teaching contexts is carried out and, in particular, if and how the use of the L1 can be a helpful tool for the foreign language teaching and learning. For this purpose the data collected at Coventry University during Italian (L2 classrooms for English students were examined. The more common and meaningful phenomena of linguistic contact between L1 and L2 were grouped according to the speaker and to their functions.

    Full Text Available Il titolo del presente contributo condensa da una parte le coordinate operative della legislazione scolastica elementare post-unitaria, in particolare riguardo all’ortoepia, e d’altra parte la ricezione di quelle coordinate nella pubblicistica scolastica elementare coeva. Il saggio considera entrambi i cardini della questione: dopo aver esposto brevemente le linee guida della legislazione circa il rapporto tra lingua e dialetti e sulla corretta pronuncia, si analizzano due strumenti didattici, concepiti per la duplice utenza dei maestri e degli alunni, nei quali si concretano due atteggiamenti sensibilmente diversi sulla questione ortoepica. Infine, dall’analisi di questi due sussidi si dedurrà il rapporto, raccomandato più o meno esplicitamente, che doveva intercorrere tra dialetto e lingua nelle aule scolastiche. «In help to the unit of language and against the mistakes coming from dialects». Spelling book and little vocabulary by Antonino TrainaThe title of this contribution epitomizes the praxis of the post-unification legislation concerning primary school, particularly about orthoepy, and the reception of that legislation by the authors of textbooksfor primary school. After having exposed the guidelines of the legislation about the relation between Italian and dialects and about correct pronunciation, this article analyzes two teaching tools (a spelling book and a vocabulary, that can be used by both teachers and students. It’s notable that the spelling book and the vocabulary have a different perspective on orthoepy. Finally, from their analysis it is deduced the model proposed for the relation between Italian and dialects in classrooms.

    Full Text Available Twenty asses of Martina Franca breed, machine milked twice a day, were used to assess the influence of milking interval (3-h, 5-h, and 8-h; N=5 and time (700, 1200 and 1900 on milk yield and udder health. Individual milk samples were taken to determine fat, protein and lactose con- tent. Sensory analysis profile was also assessed. Milk’s total bacterial count (TBC, somatic cell con- tent (SCC and udder’s skin temperature were considered to assess udder health. Milk yield increases by 28.4% (P<0.01 with a milking interval from 3-h to 8-h and is higher (P<0.01 at morning milking. The maximum milk yield per milking corresponds to 700 milking (1416.9 mL thus indicating a circa- dian rhythm in milk secretion processes. Milking intervals of 5 and 8 hours cause a decrease (P<0.01 in milk fat and lactose content. The 8-h interval leads to an increase (P<0.01 in SCC but without any significance for the health udder. No alterations about CBT, clinical evaluation and temperature of ud- der were observed. Milk organoleptic characteristics were better in the 3-h interval milking.

    Full Text Available Il metodo, che si rifà alle teorie pedagogiche di Maria Montessori (1870-1952, è un esempio di lezione “aperta” fondato su pratiche che attivano la sfera emozionale, sensoriale e relazionale oltre a quella logico-razionale della mente. Nel processo di apprendimento di conoscenze acquisite non solo attraverso l’ascolto delle parole dell’insegnante, ma anche attraverso esperienze scelte autonomamente e consapevolmente da soli e in gruppo, l’ambiente delle stazioni didattiche offre tutto il materiale di sviluppo cognitivo in maniera che sia liberamente fruibile dal discente per favorirne la socializzazione e l’autonomia (secondo il motto di Maria Montessori ‘Aiutami a fare da solo’. A lezione esse non solo offrono varietà, comunicazione e divertimento ma, e in ciò è il loro massimo pregio, differenziazione interna al gruppo degli studenti, che possono, senza alcuna pressione da parte dei compagni, lavorare al proprio ritmo e livello scegliendogli esercizi secondo le preferenze individuali lungo un percorso aperto a canali diversi di apprendimento e orientato ad un vivace interscambio con gli altri.Il nostro contributo fa riferimento a tre esempi di stazioni didattiche legate alle feste che più richiamano l’attenzione degli studenti stranieri sul nostro paese: il Natale e il Carnevale. Tali tematiche mostrano come il modello della stazioni didattiche riesca a rapportarsi al vissuto degli studenti motivandoli al raffronto interculturale.

    Salles, E.

    2003-01-01

    T. Desmarest, head of TotalFinaElf oil and gas company, has presented the 2002 results of his company in the particular context of a moving international oil situation (the Iraq crisis and the situation in Venezuela) with important consequences on markets. At the same time, the company decided to change its name into 'Total' and to adopt a new logo. The results show a 17% drop with respect to 2001 but a 10% increase of the production. The high rate of exploration successes has led to the discovery of about 1 billion of bpe with a 0.8 US$ cost per bpe, which represents the best performance of the 5 world oil majors. The rate of reserves renewal reached 151% (11.2 billions of bpe at the end of 2002). The downstream activities (refining/distribution and basic chemistry) encountered much more problems for various reasons: low economic growth, climate warmth, international instability etc.. (J.S.)

  12. Higher Order Analysis of Turbulent Changes Found in the ELF Range Electric Field Plasma Before Major Earthquakes

    Kosciesza, M.; Blecki, J. S.; Parrot, M.

    2014-12-01

    We report the structure function analysis of changes found in electric field in the ELF range plasma turbulence registered in the ionosphere over epicenter region of major earthquakes with depth less than 40 km that took place during 6.5 years of the scientific mission of the DEMETER satellite. We compare the data for the earthquakes for which we found turbulence with events without any turbulent changes. The structure functions were calculated also for the Polar CUSP region and equatorial spread F region. Basic studies of the turbulent processes were conducted with use of higher order spectra and higher order statistics. The structure function analysis was performed to locate and check if there are intermittent behaviors in the ionospheres plasma over epicenter region of the earthquakes. These registrations are correlated with the plasma parameters measured onboard DEMETER satellite and with geomagnetic indices.

    Christopoulou, Maria; Govari, Chrysa; Tsaprouni, Panagiota; Karabetsos, Efthymios

    2015-01-01

    The scope of this paper is to comparatively present the extremely low-frequency (ELF) measurements performed at four power plants in Greece, focusing on: (a) the worst-case exposure conditions, (b) the existence of magnetic field harmonic components, (c) the technical similarities among the power plants and (d) comparison of the measured percentages of reference levels at typical working areas in the power plants. A detailed measurement methodology is proposed, including broadband on-site inspection of the working areas, weighted averaged root-mean-square and peak values of magnetic flux density, percentage of reference levels, according to 1998 ICNIRP guidelines and harmonic analysis of the multi-frequency magnetic fields. During the analysis of the occupational exposure in all power plants, the new Directive 2013/35/EU has been taken into account. The study concludes by proposing a mapping procedure of working areas into certain zones, in order to take measures for workers safety. (authors)

    Full Text Available Background: An outbreak of Legionella pneumophila serogroup 1, with 403 cases was identified on the 7th November 2014 in Vila Franca de Xira, Portugal. Outbreak source was the wet cooling system of a local factory. Hospital Pulido Valente was one of the hospitals receiving patients with Legionnaires’ disease (LD. Methods: We describe the clinical findings and diagnostic methods used among the 43 confirmed or probable cases admitted to our department. Results: 60.5% were male, mean age was 56.1 ± 13.5 years and tobacco smoking was the most frequent risk factor (76.7%. All patients had fever, 62.8% ≥39.5 °C, 72.1% had chills and myalgia/arthralgia and 62.8% had dry cough. Extra pulmonary symptoms were frequent: confusion and headache occurred in 34.9% and gastrointestinal symptoms in 20.9%.High C-Reactive Protein (55.8% ≥30 mg/dL and hyponatremia (62.8% were the laboratorial abnormalities most commonly found. Hypoxemia occurred in 55.8% and hypocapnia in 93%. Urinary Antigen Test (UAT was positive in 83.7% of the cases. Conclusions: Although not specific, a combination of risk factors, symptoms and laboratory findings can be highly suggestive of LD, even in an outbreak. This should prompt diagnosis confirmation. Routine use of UAT in less severe cases of community acquired pneumonia might contribute to earlier diagnosis. Keywords: Legionnaires’ disease, Outbreak, Clinical presentation

  17. Measurement of electromagnetic waves in ELF and VLF bands to monitor lightning activity in the Maritime Continent

    Yamashita, Kozo; Takahashi, Yukihiro; Ohya, Hiroyo; Tsuchiya, Fuminori; Sato, Mitsuteru; Matsumoto, Jun

    2013-04-01

    Data of lightning discharge has been focused on as an effective way for monitoring and nowcasting of thunderstorm activity which causes extreme weather. Spatial distribution of lightning discharge has been used as a proxy of the presence or absence of deep convection. Latest observation shows that there is extremely huge lightning whose scale is more than hundreds times bigger than that of averaged event. This result indicates that lightning observation should be carried out to estimate not only existence but also scale for quantitative evaluation of atmospheric convection. In this study, lightning observation network in the Maritime Continent is introduced. This network is consisted of the sensors which make possible to measure electromagnetic wave radiated from lightning discharges. Observation frequency is 0.1 - 40 kHz for the measurement of magnetic field and 1 - 40 kHz for that of electric field. Sampling frequency is 100 kHz. Waveform of electromagnetic wave is recorded by personal computer. We have already constructed observation stations at Tainan in Taiwan (23.1N, 121.1E), Saraburi in Thailand (14.5N, 101.0E), and Pontianak in Indonesia (0.0N, 109.4E). Furthermore, we plan to install the monitoring system at Los Banos in Philippines (14.18, 121.25E) and Hanoi in Viet Nam. Data obtained by multipoint observation is synchronized by GPS receiver installed at each station. By using data obtained by this network, location and scale of lightning discharge can be estimated. Location of lightning is determined based on time of arrival method. Accuracy of geolocation could be less than 10km. Furthermore, charge moment is evaluated as a scale of each lightning discharge. It is calculated from electromagnetic waveform in ELF range (3-30 kHz). At the presentation, we will show the initial result about geolocation for source of electromagnetic wave and derivation of charge moment value based on the measurement of ELF and VLF sferics.

    2016-01-01

    The paper highlights the study on the Extremely Low Frequency (ELF) Electromagnetic Field (EMF) emission performed at an overhead 275-kV High-Voltage Transmission Lines. The study comprised of assessment at the transmission lines on 3 different cases and locations in Klang Valley, specifically on a vacant land near the transmission line, inside and around the house at the vicinity of the transmission line and the area directly under the transmission line. The instrument setup and measurement protocols during the assessment were adopted from standard measurement method and procedures stipulated under the Institute of Electrical and Electronics Engineers (IEEE) Standard. The results were compared with the standards recommended in the International Commission on Non-Ionizing Radiation Protection (ICNIRP) guidelines. The results showed that the measured field strengths are within the safety limit with the highest measured exposure was 10.8 % and 1.8 % of the permissible exposure limit for the electric and magnetic field respectively. Both the field strengths were found to drop significantly against distance from the transmission lines where closer distances showed higher field strengths. Furthermore, the study revealed that buildings and other object such as trees and shrubs screen out the electric field, resulting in a lower value at indoor measurements and near the stated objects. In addition, higher value of electric and magnetic field strengths were recorded when assessment was being done directly under the transmission line compared to the lateral measurement. (author)

  19. An entropy regularization method applied to the identification of wave distribution function for an ELF hiss event

    Prot, Olivier; SantolíK, OndřEj; Trotignon, Jean-Gabriel; Deferaudy, Hervé

    2006-06-01

    An entropy regularization algorithm (ERA) has been developed to compute the wave-energy density from electromagnetic field measurements. It is based on the wave distribution function (WDF) concept. To assess its suitability and efficiency, the algorithm is applied to experimental data that has already been analyzed using other inversion techniques. The FREJA satellite data that is used consists of six spectral matrices corresponding to six time-frequency points of an ELF hiss-event spectrogram. The WDF analysis is performed on these six points and the results are compared with those obtained previously. A statistical stability analysis confirms the stability of the solutions. The WDF computation is fast and without any prespecified parameters. The regularization parameter has been chosen in accordance with the Morozov's discrepancy principle. The Generalized Cross Validation and L-curve criterions are then tentatively used to provide a fully data-driven method. However, these criterions fail to determine a suitable value of the regularization parameter. Although the entropy regularization leads to solutions that agree fairly well with those already published, some differences are observed, and these are discussed in detail. The main advantage of the ERA is to return the WDF that exhibits the largest entropy and to avoid the use of a priori models, which sometimes seem to be more accurate but without any justification.

  20. Amplitude variations of ELF radio waves in the Earth-ionosphere cavity with the day-night non-uniformity

    2018-04-01

    The real structure of lower ionosphere should be taken into account when modeling the sub-ionospheric radio propagation in the extremely low frequency (ELF) band and studying the global electromagnetic (Schumann) resonance of the Earth-ionosphere cavity. In the present work we use the 2D (two dimensional) telegraph equations (2DTE) for evaluating the effect of the ionosphere day-night non-uniformity on the electromagnetic field amplitude at the Schumann resonance and higher frequencies. Properties of the cavity upper boundary were taken into account by the full wave solution technique for realistic vertical profiles of atmosphere conductivity in the ambient day and ambient night conditions. We solved the electromagnetic problem in a cavity with the day-night non-uniformity by using the 2DTE technique. Initially, the testing of the 2DTE solution was performed in the model of the sharp day-night interface. The further computations were carried out in the model of the smooth day-night transition. The major attention was directed to the effects at propagation paths "perpendicular" or "parallel" to the solar terminator line. Data were computed for a series of frequencies, the comparison of the results was made and interpretation was given to the observed effects.

  1. Assessment of every day extremely low frequency (Elf) electromagnetic fields (50-60 Hz) exposure: which metrics?

    Verrier, A.; Magne, I.; Souqes, M.; Lambrozo, J.

    2006-01-01

    Because electricity is encountered at every moment of the day, at home with household appliances, or in every type of transportation, people are most of the time exposed to extremely low frequency (E.L.F.) electromagnetic fields (50-60 Hz) in a various way. Due to a lack of knowledge about the biological mechanisms of 50 Hz magnetic fields, studies seeking to identify health effects of exposure use central tendency metrics. The objective of our study is to provide better information about these exposure measurements from three categories of metrics. We calculated metrics of exposure measurements from data series (79 very day exposed subjects), made up approximately 20,000 recordings of magnetic fields, measured every 30 seconds for 7 days with an E.M.D.E.X. II dosimeter. These indicators were divided into three categories : central tendency metrics, dispersion metrics and variability metrics.We use Principal Component Analysis, a multidimensional technique to examine the relations between different exposure metrics for a group of subjects. Principal component Analysis (P.C.A.) enabled us to identify from the foreground 71.7% of the variance. The first component (42.7%) was characterized by central tendency; the second (29.0%) was composed of dispersion characteristics. The third component (17.2%) was composed of variability characteristics. This study confirm the need to improve exposure measurements by using at least two dimensions intensity and dispersion.

    Electromagnetic fields are suspected of many health effects, including cancers, immunity and fertility disorders, congenital malformations, suicides and depression.... Although the results of all studies are contradictory and no biological mechanism has been found, populations are concerned about this matter. This study analyzes the absence from work of some EDF employees who are a priori the most professionally exposed to ELF EMF. Absence from work is taken as an health indicator. Although it is not specific, it can be predictive of serious health problems. The specific context of EDF has made it possible to collect and analyze the medical aspect of absence from work, that is rare in France. We were interested with employees working with high voltage (over 90 kV). Three job categories have been selected: live line workers, substation maintenance workers and substation exploitation workers (called in the company the ATEX). The first group concerned the live linemen and the results were exposed previously. It appeared they had more accidents at work, but this was more related to the job of lineman rather than to the EMF exposure. Nevertheless, substation workers have an exposure less intensive but longer than live linemen. We present here the result about the absenteeism of the substation workers, maintenance and exploitation. (author)

    Full Text Available A Zona Franca de Manaus (ZFM foi criada em 1967 pelo governo da ditadura militar brasileira, de acordo com um discurso nacionalista que apresentava a região amazônica como um território estratégico que era preciso ocupar e desenvolver. Apesar de a visão do grande vazio não ter sido apagada do imaginário popular, desde os anos de 1970 tem ganhado força a percepção da floresta como herança cultural e biológica a ser preservada. Estas mudanças nos discursos mais gerais sobre a Amazônia foram acompanhadas por um deslocamento do discurso de legitimação dos incentivos fiscais gozados pelas indústrias de Manaus, em um movimento relacionado ao processo de construção de hegemonia no campo ambiental, marcado pela emergência da chamada modernização ecológica. Utilizando a análise crítica do discurso, este artigo mostra como se constituiu o argumento de que as empresas em Manaus protegem a floresta, assentado em um roteiro de dupla ameaça: de desemprego e de desmatamento. As informações e dados foram levantados por meio de pesquisa bibliográfica, entrevistas semiestruturadas e observações diretas em reuniões e eventos corporativos. Fizeram parte do corpus, ainda, as transcrições oficiais de 64 pronunciamentos em plenário dos três senadores e oito deputados federais do Amazonas em 2007; 125 matérias publicadas no caderno de Economia do jornal A Crítica entre 1º de janeiro e 30 de junho, e quatro edições da revista institucional Suframa Hoje, no mesmo ano.La Zona Franca de Manaus (ZFM fue creada en 1967 por el gobierno de la dictadura militar brasileña, a partir de un discurso nacionalista que presentaba la región amazónica como un territorio estratégico que tenia que ser ocupado y desarrollado.

    Full Text Available O processo de globalização e a revolução digital têm trazido novos desafios de competitividade às empresas. Uma dessas novas necessidades é a mudança do foco do escopo gerencial para toda a cadeia de suprimentos. Gerenciar uma cadeia de suprimentos requer, entre outros aspectos, a integração dos "processos-chave" de negócios ao longo dessa cadeia. Nesse sentido, este trabalho teve como objetivo identificar como é a relação entre a integração de processos ao longo da cadeia de suprimentos e o desempenho no serviço prestado ao cliente (customer service. Para tanto, a abordagem exploratória foi utilizada, tendo como objeto de estudo uma cadeia de suprimentos calçadista localizada na cidade de Franca, a qual se constitui em um bom exemplo de cadeia consolidada e já inserida no mercado internacional. Os resultados obtidos permitem concluir que o desempenho do serviço ao cliente na cadeia estudada está relacionado diretamente com a integração dos processos de atendimento de pedidos, gestão da demanda e desenvolvimento de produtos ao longo da cadeia, envolvendo não apenas a integração com clientes, mas também com os fornecedores-chave. Pode-se constatar ainda que esse desempenho está relacionado também com a existência de competências internas nos processos considerados, nas empresas estudadas.The globalization process and the digital revolution have brought new challenges for the companies' competitiveness. One of these new requirements is the change of the managerial scope of the entire supply chain.

  9. ETS transcription factor ELF5 induces lumen formation in a 3D model of mammary morphogenesis and its expression is inhibited by Jak2 inhibitor TG101348.

    Chean, Jennifer; Chen, Charng-Jui; Shively, John E

    2017-10-01

    The loss of expression of a single gene can revert normal tissue to a malignant phenotype. For example, while normal breast has high lumenal expression of CEACAM1, the majority of breast cancers exhibit the early loss of this gene with the concurrent loss of their lumenal phenotype. MCF7 cells that lack CEACAM1 expression and fail to form lumena in 3D culture, regain the normal phenotype when transfected with CEACAM1. In order to probe the mechanism of this gain of function, we treated these cells with the clinically relevant Jak2 inhibitor TG101348 (TG), expecting that disruption of the prolactin receptor signaling pathway would interfere with the positive effects of transfection of MCF7 cells with CEACAM1. Indeed, lumen formation was inhibited, resulting in the down regulation of a set of genes, likely involved in the complex process of lumen formation. As expected, inhibition of the expression of many of these genes also inhibited lumen formation, confirming their involvement in a single pathway. Among the genes identified by the inhibition assay, ETS transcription factor ELF5 stood out, since it has been identified as a master regulator of mammary morphogenesis, and is associated with prolactin receptor signaling. When ELF5 was transfected into the parental MCF7 cells that lack CEACAM1, lumen formation was restored, indicating that ELF5 can replace CEACAM1 in this model system of lumenogenesis. We conclude that the event(s) that led to the loss of expression of CEACAM1 is epistatic in that multiple genes associated with a critical pathway were affected, but that restoration of the normal phenotype can be achieved with reactivation of certain genes at various nodal points in tissue morphogenesis.

  12. ULF-ELF Electromagnetic Emissions Over the Fault in Kangra Valley of India and their Relation With Radon Emanation (Intercosmos 24 Satellite Data)

    Mikhailov, Yu.M.; Mikhailova, G.A.; Kapustina, O.V.

    1999-01-01

    Experimental investigations of space and spectral characteristics of the electric component of the electromagnetic waves in the outer ionosphere in the ULF (f < 30 Hz) and ELF (f < 1 kHz) ranges were carried out over north fault of the India - Australian plate. Records of the 10 narrow band filters in the frequency range from 8 to 970 Hz with NVK-receiver mounting on Intercosmos 24 satellite were used. In the day-time at sensitivity level near 2 μV/m emissions couldn't observe. In the night-time emissions, localized exactly in space above the fault, was observed in mentioned full frequency range. In spectral distribution of emission maximum in frequency range from 150 to 623 Hz allocated. In those days, when anomalous bursts of radon concentration in underground waters in Kangra Valley was observed the simultaneous amplification of electric component of field at frequency 8 Hz more on the factor more than ten and in frequency range from 150 to 623 Hz, where usually was maximum, on the factor two or three also was observed. This fact ensures statement, that the noises are generated by the lightning discharges, but amplification of their intensity on satellite heights was related with decreasing of ELF waves attenuation in the time of their penetration through lower ionosphere, modified by electric field in preparing phase of the earthquakes.

    Chen, Y C; Chen, C C; Cheng, Y T; Tu, W; Tseng, F G

    2010-01-01

    This paper presents a platform technology with experimental results that show the scientists and biologists a way to rapidly investigate and analyze the biological effects of localized extremely low frequency (ELF) electromagnetic field (EMF) on living cells. The proximity effect of the localized ELF-EMF on living cells is revealed using the bio-compatible microplatform on which an on-glass inductive coil array, the source of the localized ELF-EMF in micro scale, is designed, fabricated and operated with a field strength of 1.2 ± 0.1 mT at 60 Hz for cell culturing study. After a 72 h ELF-EMF exposure, HeLa (human cervical cancer) and PC-12 (rat pheochromocytoma) cells exhibit about 18.4% and 12.9% cell proliferation rate reduction, respectively. Furthermore, according to the presented dynamic model, the reduction of the proliferation can be attributed to the interference of signal transduction processes due to the tangential currents induced around the cells

  18. Anomalous ELF phenomena in the Schumann resonance band as observed at Moshiri (Japan in possible association with an earthquake in Taiwan

    M. Hayakawa

    2008-12-01

    Full Text Available The ELF observation at Moshiri (geographic coordinates: 44.29° N, 142.21° E in Hokkaido, Japan, was used to find anomalous phenomena in the Schumann resonance band, possibly associated with a large earthquake (magnitude of 7.8 in Taiwan on 26 December 2006. The Schumann resonance signal (fundamental (n=1, 8 Hz; 2nd harmonic, 14 Hz, 3rd harmonic, 20 Hz, 4th, 26 Hz etc. is known to be supported by electromagnetic radiation from the global thunderstorms, and the anomaly in this paper is characterized by an increase in intensity at frequencies from the third to fourth Schumann resonance modes mainly in the BEW component with a minor corresponding increase in the BNS component also. Spectral modification takes place only in the interval of 21:00 UT±1 h, which corresponds to the global lightning activity concentrated in America. While distortions were absent in other lightning-active UT intervals, in particular, around 08:00 UT±1 h (Asian thunderstorms and around 15±1 h (African lightning activity. The anomaly occurred on 23 December three days prior to the main shock. The results observed were explained in terms of ELF radio wave perturbation caused by the lower ionospheric depression around the earthquake epicenter. The difference in the path lengths between the direct radio wave from an active global thunderstorm center and the wave scattered from the non-uniformity above Taiwan causes interference at higher resonance modes, which is successful in explaining the observational data.

  19. Theoretical analysis of the binding of iron(III) protoporphyrin IX to 4-methoxyacetophenone thiosemicarbazone via DFT-D3, MEP, QTAIM, NCI, ELF, and LOL studies.

    Nkungli, Nyiang Kennet; Ghogomu, Julius Numbonui

    2017-07-01

    Thiosemicarbazones display diverse pharmacological properties, including antimalarial activities. Their pharmacological activities have been studied in depth, but little of this research has focused on their antimalarial mode of action. To elucidate this antimalarial mechanism, we investigated the nature of the interactions between iron(III) protoporphyrin IX (Fe(III)PPIX) and the thione-thiol tautomers of 4-methoxyacetophenone thiosemicarbazone (MAPTSC). Dispersion-corrected density functional theory (DFT-D3), the quantum theory of atoms in molecules (QTAIM), the noncovalent interaction (NCI) index, the electron localization function (ELF), the localized orbital locator (LOL), and thermodynamic calculations were employed in this work. Fe(III)PPIX-MAPTSC binding is expected to inhibit hemozoin formation, thereby preventing Fe(III)PPIX detoxification in plasmodia. Preliminary studies geared toward the identification of atomic binding sites in the thione-thiol tautomers of MAPTSC were carried out using molecular electrostatic potential (MEP) maps and conceptual DFT-based local reactivity indices. The thionic sulfur and the 2 N-azomethine nitrogen/thiol sulfur of, respectively, the thione and thiol tautomers of MAPTSC were identified as the most favorable nucleophilic sites for electrophilic attack. The negative values of the computed Fe(III)PPIX-MAPTSC binding energies, enthalpies, and Gibbs free energies are indicative of the existence and stability of Fe(III)PPIX-MAPTSC complexes. MAPTSC-Fe(III) coordinate bonds and strong hydrogen bonds (N-H···O) between the NH 2 group in MAPTSC and the C=O group in one propionate side chain of Fe(III)PPIX are crucial to Fe(III)PPIX-MAPTSC binding. QTAIM, NCI, ELF, and LOL analyses revealed a subtle interplay of weak noncovalent interactions dominated by dispersive-like van der Waals interactions between Fe(III)PPIX and MAPTSC that stabilize the Fe(III)PPIX-MAPTSC complexes.

  20. Unha lingua de signos galega?

    Cristina González Abelaira

    2016-01-01

    Full Text Available The passage in 2007 of Law 27/2007 of October 23, which recognizes Spanish sign language and regulates the means of communication support for deaf, hearing-impaired or deaf and blind people, marked the beginning of official recognition for Spanish sign lan- guage (LSE and Catalan sign language (LSC, and the right to learn and use them alongside other oral media. Following a historical process of campaigning by the deaf community, the new legislation acknowledges two sign languages in Spain. LSC has also received offi- cial recognition within Catalonia in the Catalan Statute of Autonomy since 2006. In 2010, Law 17/2010 of June 3 was passed; this is also concerned with Catalan sign language. However, a Galician sign language (LSG has received no recognition at either regional or state level. Spain’s recognition of only two distinct sign languages seems to be based not on internal linguistic argu- ments but rather political and social ones. A historical and emic analysis of the language planning process in Galicia through ethnographic methods reveals how linguistic diversity was managed in the community, showing that following Spanish oralization of the deaf community, linguistic uniformity was sought, resulting in a lack of recognition for different variants, including a Galician one.

  4. The preparation of particle beams for experiments of hadron physics: Slow extraction at ELFE rate at DESY and ELSA, as well as beam cooling at HERA

    Gentner, M.

    1999-02-01

    Various complementary experimental approaches are possible to study hadron physics, all of which require dedicated accelerator facilities. One approach, known as the ELFE rate at DESY project, makes use of a continuous electron beam with an energy of 15 to 25 GeV, a current of at least 30 μA and very small emittance, for fixed target experiments. The formation of such a beam by stretching a pulsed LINAC beam with the help of the HERA electron ring has been studied. At lower beam energies and currents this concept is already being used at the ELSA facility of Bonn University. Here the extraction process has been studied intensively and has been compared with measurements. Another approach to study hadron physics is the use of an electron - ion collider. To achieve high integrated luminosities cooling of the ion beam is necessary, especially in the case of heavy ions. For HERA high energy beam cooling with the help of an electron storage ring has been studied. (orig.)

  10. Assessment of Extremely Low Frequency (ELF Electric and Magnetic Fields in Hamedan High Electrical Power Stations and their Effects on Workers

    Farshid Ghorbani Shahna

    2011-09-01

    Full Text Available Introduction: Public and occupational exposure to extremely low frequency (ELF electric and magnetic fields induced by electrical equipment is a significant issue in the environment and at the workplace due to their potential health effects on public health. The purpose of this study was assessment of the electric and magnetic fields intensities and determination of mental and psychological effects of occupational exposure in the high voltage electric power stations in the city of Hamadan, Iran. Material and Methods: The intensities of the magnetic and electric fields were measured at eight high voltage electric power stations at three different intervals of sources using an HI-3604 instrument. A two-part questionnaire was used to assess mental and psychological effects of the exposure to these fields. Two groups of control and case workers including 30 samples were selected to determine the exposure effects. Results: The results of field measurements showed the highest average electric field intensity was related to the CVT unit with 3110 V/m at a 2 m distance from the source and the lowest average was related to the control room with 1.35 V/m next to the source. Also, the highest and lowest magnetic field intensities were close to the transformator 2 and the battery room (50.42 and 1.31 mG, respectively. Discussion and Conclusion: The intensities of electric and magnetic fields in the selected stations are lower than the ACGIH and ICNIRP standard levels for occupational exposures. The results obtained indicate that the distribution of these fields was nonlinear around the sources and the effects observed on exposed workers were non-thermal.

    2015-12-01

    This article is devoted to describing the theory, technique, and first experimental results of a control source electromagnetic (CSEM) study of the Earth's crust and ionosphere with the use of two mutually orthogonal industrial transmission lines 109 and 120 km in length in the frame of FENICS (Fennoscandian Electrical Conductivity from Natural and Induction Control Source Soundings) experiment. The main part of the measurements is executed on the territory of the Fennoscandian shield at distances from the first hundreds kilometers up to 856 km from the source with the purpose of the deep electromagnetic sounding of the Earth's crust and upper mantle. According to the results of these studies clarifying the parameters of "normal" (standard) geoelectric section of the lithosphere to a depth of 60-70 km, the anisotropy parameters are evaluated and a geothermal and rheological interpretation in conjunction with the analysis of the seismic data is executed. Furthermore, to study the propagation of ELF-LLF waves (0.1-200 Hz) in an "Earth-Ionosphere" waveguide, the measurements are carried out apart from Fennoscandian shield at distances up to 5600 km from the source (in Ukraine, Spitsbergen, Poland, Kamchatka, and other areas). According to the results of these studies, the experimental estimates of the influence of the ionosphere and of the displacement currents on the propagation of ELF-ULF waves in the upper half-space at the different azimuths generation of the primary field are obtained.

  12. Curly arrows meet electron density transfers in chemical reaction mechanisms: from electron localization function (ELF) analysis to valence-shell electron-pair repulsion (VSEPR) inspired interpretation.

    Andrés, Juan; Berski, Sławomir; Silvi, Bernard

    2016-07-07

    Probing the electron density transfers during a chemical reaction can provide important insights, making possible to understand and control chemical reactions. This aim has required extensions of the relationships between the traditional chemical concepts and the quantum mechanical ones. The present work examines the detailed chemical insights that have been generated through 100 years of work worldwide on G. N. Lewis's ground breaking paper on The Atom and the Molecule (Lewis, G. N. The Atom and the Molecule, J. Am. Chem. Soc. 1916, 38, 762-785), with a focus on how the determination of reaction mechanisms can be reached applying the bonding evolution theory (BET), emphasizing how curly arrows meet electron density transfers in chemical reaction mechanisms and how the Lewis structure can be recovered. BET that combines the topological analysis of the electron localization function (ELF) and Thom's catastrophe theory (CT) provides a powerful tool providing insight into molecular mechanisms of chemical rearrangements. In agreement with physical laws and quantum theoretical insights, BET can be considered as an appropriate tool to tackle chemical reactivity with a wide range of possible applications. Likewise, the present approach retrieves the classical curly arrows used to describe the rearrangements of chemical bonds for a given reaction mechanism, providing detailed physical grounds for this type of representation. The ideas underlying the valence-shell-electron pair-repulsion (VSEPR) model applied to non-equilibrium geometries provide simple chemical explanations of density transfers. For a given geometry around a central atom, the arrangement of the electronic domain may comply or not with the VSEPR rules according with the valence shell population of the considered atom. A deformation yields arrangements which are either VSEPR defective (at least a domain is missing to match the VSEPR arrangement corresponding to the geometry of the ligands), VSEPR compliant

    Full Text Available La formazione rappresenta uno strumento basilare nella promozione della lingua e della cultura italiana. L’argomento è articolato e complesso perché abbraccia diverse questioni. Da un lato va sostenuto l’utilizzo di mezzi adeguati, come quello telematico, che favoriscono e facilitano la diffusione all’estero. Dall’altro la proposta didattica di università e scuole deve essere riorganizzata alla luce delle nuove esigenze formative. Il ruolo degli atenei italiani potrebbe diventare più incisivo se si adeguassero maggiormente agli standard esteri, in modo da favorire la circolazione di studenti anche verso e non soltanto dall’Italia. Per quanto riguarda, invece, il tipo di formazione da sostenere, va riqualificata quella umanistica e tradizionale, non perché rappresenti la cultura nella sua totalità ma perché costituisce un patrimonio che caratterizza il nostro paese e non deve andare perso.

    Full Text Available Abstract – The huge increase in migration flows through the Afro-Mediterranean routes during recent decades has shaped previously homogeneous populations into linguistically and culturally diverse ethnoscapes. Migration has therefore made a notable contribution to the acquisition and the use of English as a first, second and foreign language and to the burgeoning of new Englishes all over the world (Crystal 1997; Trudgill et al. 2002; Jenkins, 2003 thus questioning our traditional knowledge of language as a social projection of territorial unity held together by shared behavioral norms, beliefs and values. Specifically, by examining the communicative and translation processes which twelve interviewed interpreters, translators and language mediators were involved in during their interaction with newly-arrived migrants in Southern Italy, this paper addresses three main research issues concerning: a the use of English as a Lingua Franca (ELF in the practice of language and cultural mediation and the extent to which this language may be perceived either as a barrier or as a bridge, thus affecting the relationship between the mediator and the migrant and the shaping of the politics of hospitality in the Mediterranean; b the different linguistic and extra-linguistic strategies which mediators can adopt in the field of migration emergencies not only to serve communicative purposes, but also to humanize the migrants’ transfer to, and stay at the different camps across Italy; c the interviewed language mediators’ narratives as a testimony of negotiation, activism and resistance to the strict institutionalized protocols of Italian immigration policies. Finally, in this chapter, we also intend to investigate the extent to which the interviewed mediators form not a mere aggregation of individuals achieving the task of translation as a mere linguistic transfer, but a community of practice held together by a conscious and critical sense of the

  16. Nature of the bonding in the AuNgX (Ng = Ar, Kr, Xe; X = F, Cl, Br, I) molecules. Topological study on electron density and the electron localization function (ELF).

    Makarewicz, Emilia; Gordon, Agnieszka J; Berski, Slawomir

    2015-03-19

    Topological analysis of the electron localization function (ELF) has been carried out for the AuNgX (Ng = Ar, Kr, Xe; X = F, Cl, Br, I) molecules using the wave function approximated by the CCSD, MP2, and DFT(B3LYP, M062X) methods including zero-order regular approximation (ZORA). In the Ng-F bond, the bonding disynaptic attractor V(Ng,F) is missing; therefore, there are no signs of the covalent binding. The nature of the Au-Ng bond depends on the computational method used. Analysis of the ELF carried out for the AuArF and AuXeF molecules, with the wave function approximated by the CCSD and MP2 methods, shows the V(Au,Ng) attractor possibly corresponding to a partially covalent binding between the gold and noble gas atom. However, its very small basin population (<1e) and a very large value of the variance of the basin population suggest that the Au-Ng bond has a very delocalized character. Such bond nature may be related to the charge shift concept with a resonance of the Au(-+)NgX, Au(+-)NgX hybrids. The weakest Au-Ng bond, in terms of the smallest amount of electron density for the V(Au,Ng) basin, is found for the AuKrF molecule with the CCSD method (0.13e). The MP2 method, however, does not yield any V(Au, Ng) population; hence, the covalent Au-Kr bond is not confirmed. Because the V(Au,Ng) attractor is also not observed with the DFT method, the proper characterization of the Au-Ng bond requires proper description of correlation effects. Additional studies on the Au2 and [AuXe](+) molecules, performed at the CCSD and B3LYP levels, exhibit no V(Au,Au) and V(Au,Xe) bonding basins either.

  3. Why Should We Prevent a Global Anglo-American Life-World? A Democratic-Deliberative Answer

    Morales-Gálvez Sergi

    2016-10-01

    Full Text Available Should English be promoted as a worldwide lingua franca for justice-related reasons? Philippe Van Parijs answers affirmatively in order to promote global distributive justice. In contrast, I argue that a rapid expansion of English could lead to one undesirable consequence that ought to be prevented: the globalization of an Anglo-American life-world that impoverishes democratic-deliberative debates. Inspired by John Stuart Mill, I will defend the idea that the more dominant the Anglo-American life-world is, the less diversity of life-worlds and, therefore, the less diversity of substantial voices in the global democratic-deliberative process there will be. It might be that more voices could be heard (because of the lingua franca, but with less substantial diversity of opinions. In that sense, the life-worlds (and language as an access key to them have an instrumental value that enables plurality and better deliberative discussion. For that reason, I contend that there is a pro tanto reason to prevent the expansion of English as a lingua franca.

Several factors affects the variation of the indexes of infestation and reproduction, such as climate, bee breed, development time, hygienic behavior; being that temperature is a environmental variable that acts on the variation of these indexes: the infestation increases in the colder months and decrease in warmer months, so in the months of autumn and winter occurs the biggest infestation by varroa in the beehives. Were evaluated the indexes of infestation by V. destructor on adult worker and brood cells to ascertain how these indexes rates, in months of autumn, in an africanized bees apiary located in region of Cerrado, surrounded by plantations of sugar cane, with a tropical climate and food in nature. The sample was collected in two years, in the months of May and June 2005 and April and June 2007 in the Experimental Apiary of Franca University-UNIFRAN, located in the municipality of Restiga-SP. The medium indexes of infestation in broods were higher in May/2005 (12.44% than June/2005 (7.78%, were also higher in April/2007 (3% than in June/2007 (0%; all the differences weren’t statistically significant.

    Full Text Available Clinically significant portal hypertension (CSPH, defined as hepatic venous pressure gradient (HVPG ≥10 mmHg, causes major complications. HVPG is not always available, so a non-invasive tool to diagnose CSPH would be useful. VWF-Ag can be used to diagnose.

  7. Assessment of inhomogeneous ELF magnetic field exposures

    Leitgeb, N.; Cech, R.; Schroettner, J.

    2008-01-01

    In daily life as well as at workplaces, exposures to inhomogeneous magnetic fields become very frequent. This makes easily applicable compliance assessment methods increasingly important. Reference levels have been defined linking basic restrictions to levels of homogeneous fields at worst-case exposure conditions. If reference levels are met, compliance with basic restrictions can be assumed. If not, further investigations could still prove compliance. Because of the lower induction efficiency, inhomogeneous magnetic fields such as from electric appliances could be allowed exceeding reference levels. To easily assess inhomogeneous magnetic fields, a quick and flexible multi-step assessment procedure is proposed. On the basis of simulations with numerical, anatomical human models reference factors were calculated elevating reference levels to link hot-spot values measured at source surfaces to basic limits and allowing accounting for different source distance, size, orientation and position. Compliance rules are proposed minimising assessment efforts. (authors)

  10. Preschool Children Differentiation According to the Lingua- Grammatical Categories Development

    Z. V. Polivara

    2012-01-01

    Full Text Available The parallel existence of languages and cultures brings forward the necessity of studying this linguistic phenomenon and designing special methods of speech development for the bilingual children. The particular attention should be given to the preschool age, for according to A. A. Leontyev’s study, the parallel acquiring of two languages often results in insufficient development of socio-linguistic speech standards. The research is devoted to the phenomenon of the two language systems coexistence in a bilingual person’s consciousness, both of them functioning and encoding the same subjects and phenomena. The peculiarities of language interference are described with the reference to the Russian-Tatar bilingual environment. The author believes that the bilingual interference problems are not caused by the phonetic and grammar system differences of the two languages. To find out the potential source of inter-language transition and interrelations between the native and non-native languages, it is necessary to identify the cognitive, neurolinguistic and psycho-linguistic aspects. Therefore, the regional phenomenon of mass bilingualism among the Tatar population is examined by the author in the framework of the psycho-linguistic and cognitive approaches. The paper presents the model of the lexical and grammar categories formation based on differentiated preschool teaching of the bilingual children. The proposed model makes it possible to overcome the limited viewpoint on the general speech dysfunctions, as well as the specifics of lexical and grammar categories development. It can be used for the further development of educational programs in psycho-linguistics, ethno-linguistics, onto-linguistics, cognitive linguistics, social-linguistics, contrastive linguistics and the language theory by means of extending the teaching course content.

    Full Text Available Abstract – In this paper I focus on the polylinguistic and polycultural landscape of Milan on the theoretical basis of daily life studies, the sociolinguistics of globalization, and intercultural pragmatics. The relevance of this field is determined by the need for urban anthropology to semiotize the urban spaces as an interpretative bridge between the microsystem (the individual level and the macrosystem (the social level. More concretely, I investigate the presence of the Spanish language in the superdiversity of Milan and, methodologically, I collect ethnographically and interpret qualitatively a corpus of 700 daily life texts of various types of street writing. The results show the significant presence of Spanish in the urban landscape and a high level of hybridism which is, nevertheless, totally functional in communication. I also detect the emergence of linguistic, pragmatic and intercultural awareness in the writers. Finally, with some precautions, I confirm the scientific potential of the daily life documents to investigate complex urban dynamics.Resumen – El tema de este estudio es el panorama polilingüe y policultural de Milán y se plantea a partir de las bases teóricas de los everyday life studies, de la sociolingüistica de la globalización y de la pragmática intercultural.

Concretamente, el objetivo es investigar el papel del idioma español en la supediversidad milanesa; la metodología es de etnografía urbana con la formación e interpretación cualitativa de un corpus fotográfico de setecientos textos cotidianos de escritura callejera (pintadas, avisos, grafiti, ecc.. Los datos relevan una presencia significativa del español en el landscape milanés, con un alto nivel de hibridismo que, de todas formas, es funcionalmente adecuado y denota el emerger de la conciencia  lingüística, pragmática e intercultural de los hablantes-escritores.

  17. Il teatro di lingua tedesca tra Restaurazione e Naturalismo

    Rita Svandrlik

    2014-12-01

    Full Text Available This article outlines the development of nineteenth-century theatre from a sociological viewpoint, in particular, focusing on the coming of age of the Wiener Volkstheater under the direction of Raimund and Nestroy, as well as with the staging of works by playwrights as different from each other as Grabbe, Grillparzer and Büchner. All three of them, from different angles, tackled the historical genre as well as the problem of theatre seen in a new light. However, it was not their plays that were successful during the period of the Restoration but rather grand scale historical dramas on familiar themes by mostly forgotten playwrights, often translations and adaptations of French and Classical works. In the decades that followed the Revolution of 1848, in which fiction was the dominant literary genre, Hebbel renovated tragedy as form, whereas Wagner went on to reform theatre at all levels.

  18. La lingua letteraria in Ucraina: ieri e oggi

    Giovanna Brogi Bercoff

    2005-12-01

    Full Text Available The Question of Literary Language in Ukraine in Past and Present In the last few years the “language question” has gained momentum in the scholarly debate and social life in Ukraine. The Author suggests that multilingualism, as an expression of multiculturalism, is a distinctive feature of Ukraine through all its historical developement. On the basis of evidence drawn from texts of the 17th-18th centuries (epistolography, panegyric literature the Author aims at showing that multilingualism was one of the main characters distiguishing Ukraine from the Russian tradition; multilingualism testified to the close ties between Ukrainian culture and western Renaissance and Baroque, at the same time contributing to the creation of original literary forms with peculiar features. For the 19th century it is impossible to consider Kyiv’s culture without taking into account the contribution given by writers and intellectuals who used Russian language. While Kyiv was certainly a Ukrainian city, its culture exhibited different linguistic and cultural layers (Ukrainian, Russian, Jewish, Polish, German that coexisted both in parallel streams and in reciprocal contacts. To reconstruct the peculiar and very complicated “Kyivan text” of culture in the 19th-beginning 20th century is one of the main desiderata for future research. The multilingual tradition – with its positive and negative characteristics – cannot be ignored in contemporary civil and scientific work. However, in our days Ukrainian language has reached such a high level of developement and perfect modern functionality that its use and universal diffusion in public and private life is a priority for the future developement of Ukraine and its culture. The existence of an extremely interesting literature and a lively cultural life makes Ukrainian a prestigious literary language, a perfect means of communication for private and state life. The Ukrainian government should give its strongest support for the consolidation of Ukrainian language, for the developement of Ukrainian-language literature, press and mass-media, and for the diffusion of knowledge about Ukrainian language and culture in European countries. The prestige of a nation is increased also by the image a country succeeds in transmitting to other countries, a fact which – in its turn – contributes to the strengthening of internal stability and self-consciousness.

    2017-10-01

    Preliminary results from the study show a difference in the language habits between older and younger generations on New Caledonians of Melanesian descent. Although French is perceived as the lingua franca by all, English is more valued than ancestral Melanesian languages by the younger generations. In terms of cultural representations and links with family history, there seems to be a discrepancy between the younger and the older generations. Whilst the older generations perceive the Centre Culturel Tjibaou as a traditional space for Melanesian art and culture their younger counterparts on the contrary view it as a place associated with contemporary art and music performances.

    2016-04-15

    Since Paris's historical climate agreement, it has become clear that from now on energy supply will be discussed worldwide on the premise of decarbonisation. Germany as a traditional coal country and as a land of energy transition can no longer avoid this debate. After all, the climate targets that have been adopted several times for 2030, 2040 and 2050 will ultimately mean the end of coal-fired power generation. In January 2016, Agora Energiewende presented a proposal with the eleven cornerstones for a coal consensus on how such an exit from coal-fired power generation could look like. We are concerned with a cross-party consensus that is broadly anchored in society, which gives all parties involved planning security and reliability and at the same time paves the way for a socially balanced and fairly structured transition to the new energy system. The impacts are particularly relevant for the brown coal regions concerned. In order to make the gradual phasing out of coal-fired power generation socially and economically compatible, special attention must be paid to open-cast brown coal mines and power plants as well as to regional structural change. This publication therefore takes a closer look at precisely these aspects. [German] Seit dem historischen Klimaabkommen von Paris ist klar: Die Energieversorgung wird von nun an weltweit unter der Praemisse der Dekarbonisierung diskutiert. Deutschland als traditionelles Kohleland und als Land der Energiewende kann dieser Debatte nicht laenger ausweichen.

  16. Saving turtles: Talisman, Elf and BHP make room for reptiles

    Lorenz, A.

    1999-05-03

    Cooperation between Australia`s BHP Petroleum, Canada`s Talisman Energy and France`s El Aquitaine to help the Trinidadian government and conservation groups to save the nesting grounds of the Carribean sea turtle is described. The nesting ground is located near one of the projects the three companies are working on. The giant turtle, also called the leatherback, can weigh as much as a tonne and have a 2.4 metre flipper span, have their nesting places on Trinidad`s northeastern shore. The three companies are working in 36 metres of water opposite two of the turtles` last nesting places. Had the companies proceeded as planned, the project could have destroyed their nesting place. Instead, the companies put up $90,000 for a three-month research project to monitor the movement of the turtles with satellite telemetry. In order to assess the turtles` hearing, tiny wires were inserted in the the turtles` brain to measure brain wave patterns - a method similar to that used on human neo-natals. When it was discovered that the turtles did not adapt well to captivity, they were fitted with earphones and transmitter during 10-minute period when they were in the quiescent state of egg-laying. The companies proceeded with a seismic program that used cables on the sea floor. Rather than use a large and noisy survey vessel to lay long streamers on a wide area, they laid shorter strips on a grid with smaller, quieter boats. That was sufficient for the turtles to continue normal activity as females arrived on the beach in the usual numbers to nest and to lay eggs. The documentation provided to the Trinidadian government was well received and plans are afoot to use it as a benchmark in assessing future exploratory applications within Trinidadian jurisdiction.

    Kavet, R

    1999-07-01

    Residential measurements of ambient power frequency magnetic fields may serve as surrogates for personal exposures. There are few data available, however, to determine how far back in time this surrogacy holds. A limited amount of research on residential transients suggests that, all other factors being equivalent, larger transients may propagate within VHCC neighbourhoods than within LCC neighbourhoods. However, the presence of a conductive residential ground pathway also appears to be a potentially important factor associated with residential transient activity. The use of the TWA metric was prompted by the need for an exposure score simple enough to summarise an individual's exposure over a prior interval, yet specific to the agent of concern, namely the power frequency magnetic field. To the extent that the TWA exposure is associated with health outcomes in the absence of bias, including confounding, the TWA metric is important. (author)

    According to Quantum Electro-Dynamical Theory by G. Preparata, liquid water can be viewed as an equilibrium between of two components: coherent and incoherent ones. The coherent component is contained within spherical so called "coherence domains" (CDs) where all molecules synchronously oscillate with the same phase. CDs are surrounded by the incoherent component where molecules oscillate with casual phases regarding each other. The existence of coherent domain in water has been demonstrated in a set of experiments on pure water exposed to high voltage, under this condition the electric field concentrates inside the water, arranging the water molecules to form high ordered structure. Recently has been studied the influence of combined static and alternating parallel magnetic fields on the current through the aqueous solution of glutamic acid; outlining the relevance of low frequency electro-magnetic field in interacting with biological target. Additional results demonstrate that at combined static and alternating parallel, magnetic fields matching the ion cyclotron energy resonance of a particular charged molecule into biological tissue an intrinsic weak magnetic field is generated by ion currents in the cell. These results should increase the reliability and the clinical feasibility of the use of electromagnetic field, tuned at ion cyclotron resonance of charged molecules, as a biophysical approach to interfere with biological mechanisms. We demonstrate that Exposure of human epithelial cell to ion cyclotron energy resonance generated by a commercial electromedical device (Vega select 719) tuned to calcium ion at 7 Hz act as a differentiation factor, thus opening up the possibility to use particular extremely low frequency electro magnetic field protocols, in informative medicine.

    We conducted a pilot study to assess magnetic field levels in electric compared to gasoline-powered vehicles, and established a methodology that would provide valid data for further assessments. The sample consisted of 14 vehicles, all manufactured between January 2000 and April 2009; 6 were gasoline-powered vehicles and 8 were electric vehicles of various types. Of the eight models available, three were represented by a gasoline-powered vehicle and at least one electric vehicle, enabling intra-model comparisons. Vehicles were driven over a 16.3 km test route. Each vehicle was equipped with six EMDEX Lite broadband meters with a 40-1,000 Hz bandwidth programmed to sample every 4 s. Standard statistical testing was based on the fact that the autocorrelation statistic damped quickly with time. For seven electric cars, the geometric mean (GM) of all measurements (N = 18,318) was 0.095 µT with a geometric standard deviation (GSD) of 2.66, compared to 0.051 µT (N = 9,301; GSD = 2.11) for four gasoline-powered cars (P electric vehicles covered the same range as personal exposure levels recorded in that study. All fields measured in all vehicles were much less than the exposure limits published by the International Commission on Non-Ionizing Radiation Protection (ICNIRP) and the Institute of Electrical and Electronics Engineers (IEEE). Future studies should include larger sample sizes representative of a greater cross-section of electric-type vehicles. Copyright © 2012 Wiley Periodicals, Inc.

    1978-01-01

    Two systems for exposure and sham-exposure of large numbers of rats and mice to uniform, vertical, 60-Hz electric fields have been constructed. The rat system contains four racks of four rectangular 1.0m x 2.2m exposure-electrodes that are stacked vertically with a separation between adjacent electrodes of 0.41 m. Any two of the four exposure racks may be energized to a maximum field strength of 150 kV/m. Each exposure electrode is equipped with 24 Lexan cages, each of which holds a single rat. The cage floor is a stainless steel screen that serves as one electrode. The system for watering animals is contained entirely within the electrode and does not protrude above the cage's floor, thereby preventing distortion of the exposure field and electrical shock or discharge as the animal drinks. The total capacity of the system is 288 rats. A similar system of two racks of five electrodes each is used to expose as many as 450 mice to fields at a maximum strength of 150 kV/m while sham exposing an equal number. Measurements of the electric field reveal an overall uniformity within 4% over the area to be occupied by experimental animals. The field inside a Lexan cage is reduced by about 3%. No corona-discharge has been detected. Measurements of ozone concentration in the rat and mouse exposure systems show no difference from background levels. Harmonic distortion has been eliminated by damping and filtering the high-voltage supply. Animals housed in close proximity are partially shielded from the electric field; the total body current in a rat model is reduced by 35 ± 5% when rats are placed in adjacent cages. (author)

  7. Two types of magnetospheric ELF chorus and their substorm dependences

    Tsurutani, B.T.; Smith, E.J.

    1977-01-01

    Extremely low frequency (10--1500 Hz) magnetospheric chorus has been analyzed to investigate a possible dependence on substorms. Care was taken to separate effects from temporal effects by analyzing an entire year of data acquired by the Ogo 5 search coil magnetometer. A major finding of the study of spatial dependences is that chorus occurs principally in two magnetic latitude regions. Equatorial chorus is detected near the equator, and high-latitude chorus is found at magnetic latitudes above 15 0 . When chorus in these two regions is analyzed separately, substorm dependences become apparent. Comparisons with AE indicate that equatorial chorus occurs primarily during substorms. High-latitude chorus is not strongly dependent on AE and often occurs during intervals of prolonged quiet with AE 0 , a region where cyclotron resonance is most efficient. The L value of maximum chorus occurrence increases from 5--8 postmidnight to 7--11 postdawn, a dependence which is consistent with generation by electrons which have undergone drift shell splitting. Delay times between substorms and the onset of equatorial chorus are consistent with a gradient drift of approx.25-keV electrons. Equatorial postmidnight chorus and postdawn chorus have similar occurrence rates and wave intensities. The maximum chorus ocurrence rates are 54% postmidnight and 56% postdawn

  8. African literacies: Which of them matter, and why?

    Kate Parry

    2010-05-01

    Full Text Available This paper draws on data collected at the Kitengesa Community Library in Masaka District of Uganda to discuss some of the different literacies that are important in African environments. First, the literacies associated with different languages are analysed, these being classified assupralanguages (English in Uganda, lingua francas (such as Kiswahili, and local languages (Luganda in Kitengesa. Literacies also vary with social context, and the paper considers the cases of school, family, peer group, and private literacies. Work at Kitengesa has shown that although literacy is generally thought of as part of school life, other literacies are developing in response to the opportunities provided by the library. Supralanguage and school literacies remain dominant, but it is argued that they will become much more productive if supported by other literacies and that it is a major function of a community library to help such other literacies to develop

    Full Text Available This article explores the Beat music scene in Hamburg, West Germany, in the early 1960s. This scene became famous for its role in incubating the Beatles, who played over 250 nights there in 1960–62, but this article focuses on the prominent role of fans in this scene. Here fans were welcomed by bands and club owners as cocreators of a scene that offered respite from the prevailing conformism of West Germany during the Economic Miracle. This scene, born at the confluence of commercial and subcultural impulses, was also instrumental in transforming rock and roll from a working-class niche product to a cross-class lingua franca for youth. It was also a key element in West Germany's broader processes of democratization during the 1960s, opening up social space in which the meanings of authority, respectability, and democracy itself could be questioned and reworked.

  18. The decline and fall of Esperanto: lessons for standards committees.

    Patterson, R; Huff, S M

    1999-01-01

    In 1887, Polish physician Ludovic Zamenhof introduced Esperanto, a simple, easy-to-learn planned language. His goal was to erase communication barriers between ethnic groups by providing them with a politically neutral, culturally free standard language. His ideas received both praise and condemnation from the leaders of his time. Interest in Esperanto peaked in the 1970s but has since faded somewhat. Despite the logical concept and intellectual appeal of a standard language, Esperanto has not evolved into a dominant worldwide language. Instead, English, with all its idiosyncrasies, is closest to an international lingua franca. Like Zamenhof, standards committees in medical informatics have recognized communication chaos and have tried to establish working models, with mixed results. In some cases, previously shunned proprietary systems have become the standard. A proposed standard, no matter how simple, logical, and well designed, may have difficulty displacing an imperfect but functional "real life" system.

  1. The current challenges of teaching ESP

    Fălăuş, A.

    2017-05-01

    Although the status of lingua franca can easily be claimed by English nowadays, there are always plenty of challenges involved in the process of teaching a foreign language. The simple mastering of the four skills (reading, writing, listening and speaking) and the acquisition of general grammar and vocabulary may not be enough in some circumstances. ESP focuses on the specific needs of the learners, concentrating more on language in context and on the students’ need to acquire a set of professional skills and particular job-related functions. This paper, consequently, focuses on identifying the current challenges that teachers and students may encounter in the process of teaching and learning English for Specific Purposes.

  2. The Moral Reasoning of U.S. Evangelical and Mainline Protestant Children, Adolescents, and Adults: A Cultural-Developmental Study.

    Jensen, Lene Arnett; McKenzie, Jessica

    2016-01-01

    This cultural-developmental interview study examined moral reasoning in relation to religious culture (evangelical, mainline Protestants), age (children, adolescents, adults), and moral issue (public, private; N = 120). Compared to adolescents and adults, children used more Ethic of Autonomy and less Ethic of Community reasoning. With age, differences between religious cultures became pronounced. Mainline adults invoked an Ethic of Divinity for private issues. Evangelical adolescents and adults used this ethic frequently, but more for public than private issues. These and other findings indicate that evangelical and mainline Protestants diverge on what should be society's moral lingua franca, and cast new and nuanced light on America's "culture wars." Results furthermore highlight comodulation of development and culture that requires life course research on moral reasoning. © 2015 The Authors.

  7. Going on exchange to Scandinavia to improve language skills

    Caudery, Tim; Petersen, Margrethe; Shaw, Philip

    Most exchange students now come to Scandinavian countries not because they are students of the languages of the countries concerned, but because they wish to experience study abroad and can do so in Scandinavia through the medium of English used as a lingua franca. This paper reports on a three......-year study (2005-2007) of the language experiences and language-related attitudes of exchange students in Sweden and Denmark. The study includes some 240 subjects who were interviewed individually three times each during their stay in Scandinavia and who all, at the end of each interview, completed a simple...... vocabulary test and a picture description test.

  8. Korbinian Brodmann (1868-1918) and his contributions to mapping the cerebral cortex.

    Loukas, Marios; Pennell, Christopher; Groat, Christopher; Tubbs, R Shane; Cohen-Gadol, Aaron A

    2011-01-01

    Korbinian Brodmann is best remembered for his classification of cortical areas based on cytoarchitecture. He was influenced by such greats as Alzheimer, Vogt, Edinger, Nissl, and Weigert. Although first presented in 1903, Brodmann's "mapping" continues to be the lingua franca of cortical localization and his writings on this topic have become neurological classics. Many of his areas have gone on to be associated with various nervous functions such as hearing (areas 41 and 42) and vision (areas 17 and 18). Few textbooks of neurology, neuroanatomy, or neurosurgery fail to mention the important maps produced by Brodmann that are still used today. The present article discusses the life and influence of Korbinian Brodmann on our understanding of the human brain.

  9. Standing in the gap: ref lections on translating the Jung-Neumann correspondence.

    McCartney, Heather

    2016-04-01

    This paper considers the experience of translating the correspondence between C.G. Jung and Erich Neumann as part of the Philemon series. The translator explores the similarities between analytical work and the task of translation by means of the concepts of the dialectical third and the interactional field. The history and politics of the translation of analytic writing and their consequences for the lingua franca of analysis are discussed. Key themes within the correspondence are outlined, including Jung and Neumann's pre-war exploration of Judaism and the unconscious, the post-war difficulties around the publication of Neumann's Depth Psychology and a New Ethic set against the early years of the C.G. Jung Institute in Zurich, and the development of the correspondents' relationship over time. © 2016, The Society of Analytical Psychology.

  10. Formalizing Darwinism and inclusive fitness theory.

    Grafen, Alan

    2009-11-12

    Inclusive fitness maximization is a basic building block for biological contributions to any theory of the evolution of society. There is a view in mathematical population genetics that nothing is caused to be maximized in the process of natural selection, but this is explained as arising from a misunderstanding about the meaning of fitness maximization. Current theoretical work on inclusive fitness is discussed, with emphasis on the author's 'formal Darwinism project'. Generally, favourable conclusions are drawn about the validity of assuming fitness maximization, but the need for continuing work is emphasized, along with the possibility that substantive exceptions may be uncovered. The formal Darwinism project aims more ambitiously to represent in a formal mathematical framework the central point of Darwin's Origin of Species, that the mechanical processes of inheritance and reproduction can give rise to the appearance of design, and it is a fitting ambition in Darwin's bicentenary year to capture his most profound discovery in the lingua franca of science.

  12. Massive Predictive Modeling using Oracle R Enterprise

    CERN. Geneva

    2014-01-01

    R is fast becoming the lingua franca for analyzing data via statistics, visualization, and predictive analytics. For enterprise-scale data, R users have three main concerns: scalability, performance, and production deployment. Oracle's R-based technologies - Oracle R Distribution, Oracle R Enterprise, Oracle R Connector for Hadoop, and the R package ROracle - address these concerns. In this talk, we introduce Oracle's R technologies, highlighting how each enables R users to achieve scalability and performance while making production deployment of R results a natural outcome of the data analyst/scientist efforts. The focus then turns to Oracle R Enterprise with code examples using the transparency layer and embedded R execution, targeting massive predictive modeling.

  13. Pronunciation Assessment in the Context of World Englishes

    Dimova, Slobodanka

    2017-01-01

    The globalization of English has initiated a debate of acceptability of competing norms, be they endonormative or exonormative (Davies, 1999; Gill, 1999). In WE’s view, exonormative orientations towards the native-speaker may be discriminatory against non-native speakers (NNS) of English, so...... it recommends a pluralized and pluricentric notion of world Englishes (Kachru, 1992). ELF’s standpoint, conversely, rejects native speaker norms in favor of endonormative realizations of lingua franca varieties. These normative issues are exacerbated, both theoretically and practically, in the context...... the Expanding Circle users, for which “phonological intelligibility” is the most important criterion (Jenkins, 2006a). The chapter will continue with a discussion of criticism of the current practices in language testing and assessment that claim that the field has failed to adopt the WE perspective...

  14. “When I speak English, I feel international”. Exchange students’ construction of social identity in Denmark

    Cancino, Rita

    “When I speak English, I feel international”. Exchange students’ construction of social identity in Denmark. Students from various countries participate in the English courses for Ph.D. and Master students at Aalborg University, Denmark. Here they try to achieve a fluency in English that permits...... them to participate in classes and to pass their exams in English, write their thesis in English, etc. The students have different nationalities and identities. While learning English, they try to adapt to Denmark and the Danish culture and language. English plays the role as the lingua franca per se...... in the globalized world and in Denmark aswell. Studies show that language influence a person’s social identity. In this paper I will present the case of a group of foreign students and the construction of identity while participating in English courses.

  15. Visual analysis of geocoded twin data puts nature and nurture on the map.

    Davis, O S P; Haworth, C M A; Lewis, C M; Plomin, R

    2012-09-01

    Twin studies allow us to estimate the relative contributions of nature and nurture to human phenotypes by comparing the resemblance of identical and fraternal twins. Variation in complex traits is a balance of genetic and environmental influences; these influences are typically estimated at a population level. However, what if the balance of nature and nurture varies depending on where we grow up? Here we use statistical and visual analysis of geocoded data from over 6700 families to show that genetic and environmental contributions to 45 childhood cognitive and behavioral phenotypes vary geographically in the United Kingdom. This has implications for detecting environmental exposures that may interact with the genetic influences on complex traits, and for the statistical power of samples recruited for genetic association studies. More broadly, our experience demonstrates the potential for collaborative exploratory visualization to act as a lingua franca for large-scale interdisciplinary research.

  16. Universitäten zwischen Mehrsprachigkeit und „international English“ – Sprachideologien und Einstellungen des Personals finnischer Universitäten zu Mehrsprachigkeit und Deutsch

    Sabine Ylönen

    2017-10-01

    Traditionally, multilingualism is valued in Finland. However, in an age of globalisation and internationalisation, with English as a lingua franca, it is worth asking what value languages other than English have. The aim of this study was to gauge the attitudes of Finnish university personnel towards the use of languages other than English, particularly German, thus revealing widespread language ideologies. The data for this study was comprised of approximately 2000 open-ended responses to a survey on the role of languages amongst Finnish university personnel in 2009. Content analysis was used to analyse the responses. The findings of this analysis showed that an ideology of multilingualism was clearly more widespread than an English-only ideology, and that the image of German has not as rapidly declined as the knowledge and use of the language. Despite this, the ideology of language use being connected to disciplines strongly persists.

  17. Intercomprehension - When Everyone Speaks Their Own Language and Understands Others

    Nataša Pirih Svetina

    2016-12-01

    Full Text Available Intercomprehension is a communication practice where two persons speak their mother tongue and are able to understand each other without being taught the language of their adressee. It is a usual practice between languages that belong to the same linguistic family, for example Slavic, Romance or Germanic languages. In the article, the authors present the notion of intercomprehension as an alternative to communication in English as a lingua franca. That kind of communication was known among Scandinavians, whereas the first teaching method was developped for Romance languages (EuRomCom at the beginning of the 21st century. Today, more methods exist including German and Slavic languages. In the article, the authors are enumerating some of them and also give a short outline of existing practices.

  18. Language attitudes and the ideology of the Nordic

    Thøgersen, Jacob Martin; Östman, Jan Ola

    2010-01-01

    This article discusses the rise and the current standing of “Norden” (the Nordic societies) as an imagined community (Anderson, Imagined communities, Verso, 1991). The ideology of Norden as a coherent community rests on the one hand on the perceived mutual intelligibility of the Scandinavian...... languages, used as mother tongue or as lingua franca. On the other hand the ideology of Norden rests on a sense of historical unity. Historically, the ideology of the Nordic grew out of the era of national romanticism. The present study therefore addresses the pertinent question of how the ideology...... of the Nordic fares in late modernity where ideology is under threat from more “rational”, e.g., financial lines of thinking....

  19. Unscrambling jumbled sentences: An authentic task for English language assessment?

    Betty Lanteigne

    2017-06-01

    Full Text Available Jumbled sentence items in language assessment have been criticized by some authors as inauthentic. However, unscrambling jumbled sentences is a common occurrence in real-world communication in English as a lingua franca. Naturalistic inquiry identified 54 instances of jumbled sentence use in daily life in Dubai/Sharjah, where English is widely used as a lingua franca. Thus it is seen that jumbled sentence test items can reflect real-world language use. To evaluate scrambled sentence test items, eight test item types developed from one jumbled sentence instance (“Want taxi Dubai you?” were analyzed in terms of interactivity and authenticity. Items ranged from being completely decontextualized, non-interactive, and inauthentic to being fully contextualized, interactive, and authentic. To determine appropriate assessment standards for English tests in schools in this region, the English language standards for schools and English language requirements for university admission in the UAE were analyzed. Schools in Dubai/Sharjah use Inner Circle English varieties of English (e.g., British or American English as the standard for evaluation, as well as non-native-English-speaker varieties (e.g., Indian English(es. Also, students applying to English-medium universities in the UAE must meet the required scores on standardized English tests including the IELTS and TOEFL. Standards for evaluation of communication in English involving tasks of jumbled sentences in classroom tests must reflect the language learning goals of the school and community. Thus standards for classroom assessment of English in Dubai/Sharjah are determined by local schools’ and universities’ policies.

    Full Text Available This article explores how the words of foreign origin (loanwords, in Chinese wailaici are integrated in the modern and contemporary Chinese language. The phenomenon of the introduction of the loanwords in Chinese has become more and more productive, specially in the last thirty years. Over the time the Chinese language has devised many strategies to integrate foreign words; most of the words of Japanese origin are introduced as graphic loans, while the words introduced by Western languages (specially English are integrated as phonemic loans, loan-translations, semantic loans, or hybrid words. In recent years, many loanwords and neologisms have been created by using the language of the network, as the acronyms written in Latin letters.

  5. «PALPITANTE, RIDENTE, NOSTALGICA, APPASSIONATA»: LA LINGUA DEI DIARI DI ANTONIA POZZI

    Giuseppe Sergio

    2013-01-01

    Full Text Available L’articolo prende in considerazione i diari della poetessa e fotografa Antonia Pozzi, nata nel 1912 e morta suicida nel 1938. Essi si presentano come particolarmente eterogenei, certo per la tipica “cavità” della forma diaristica, ma anche in ragione delle tre distinte tranches in cui vengono stesi: il Quaderno dal ’25 al ’27; le Note di viaggio nel 1933; il Diario intimo vero e proprio fra il ’35 e l’anno della morte. L’analisi si concentra sulle diverse fisionomie linguistiche dei diari e sulla funzione che Antonia Pozzi affida loro, funzione che è sia esistenziale che poetica. Nel Diario intimo, in particolare, la scrittura infatti si configura da un lato come pharmacon, pur elevandosi volentieri dalle contingenze a questioni filosofiche e letterarie, dall’altro come luogo in cui fissare immagini, riflessioni e impressioni in vista di una futura rielaborazione poetica, come dimostrano precise rispondenze fra gli uni e l’altra.  “Throbbing, laughing, nostalgic, passionate”language in the diaries of Antonia Pozzi The article studies the diaries of the poet and photographer Antonia Pozzi, born in 1912 and who committed suicide in 1938. They seem very heterogeneous due to their typical “cavity” form, but also because of their division into three separate sections: there are her notebooks from ’25 to ’27, travel notes from 1933, the intimate diary written between the '35 and the year of her death. The analysis focuses on the different language of the diaries and the functions that Antonia Pozzi gives them, functions that are both existential and poetic. In the intimate diary, in particular, the writing is on the one hand configured as a pharmacon, rising above contingencies to address philosophical and literary issues, but it is also a place to fix images, reflections and impressions in view of a future poetic revision, as shown by the precise correspondences present between them. 

  6. La città scrive: "détournements" nella cultura contemporanea di lingua francese

    Silvia Riva

    2009-12-01

    Full Text Available The marks of the events on the urban landscape are a city's writing. More than writings on a city - amongst which are the memorable work of Baudelaire, the ";flâneur";, and Apollinaire's Lettre-Océan -  they represent the analysis of the city that writes on its own texture. This phenomenon relies on a procedure of diversion and estrangement which turns famous places into uncommon areas and it finds amongst its founding models the cinematographic production of Francois Truffaut (Fahrenheit 451. A similar approach allows us to capture the significance of the work of Dominique Fourcade, one of the most important contemporary French poets. In MW Chute, a  poem dated 5th October 2001, he describes the horror of the collapse of New York City's twin towers. In this piece, Fourcade describes what happened to him on 9/11 not much from a man's perspective but rather from . a poetic standpoint. Ground Zero allows his writing to jump forward, and turn into a verbal city and labyrynth. His reflections on the urban landscape  which, collapses under the explosion become a map of dispersed images made of innumerabile détournements (detour aheads, of endless variants and deviations. The event becomes the model and shape of his writing.

    Full Text Available Global anglophony, cultural subordination and projects of language dissolution in the Italian education system. This article points out the risks associated with the proliferation of courses taught in English language in the Italian universities and high schools. This policy, argues the author, is not adequate to solve the problem of the lack of knowledge of foreign languages by Italian students and, on the other hand, it threatens to de-qualify the teaching of non-linguistic disciplines. A further deterioration of higher education in Italy seems to be the predictable outcome.

Second generation Italian speakers.   In Italian schools there is an important change which regards foreign children enrolled: every year there are more and more of them who were born in Italy and they enter the school system following the same rhythms as their native classmates while fewer and fewer foreigners arrive from their home countries to reunite with their families.  How do foreign children, born in Italy, speak?  What interlinguistic characteristics does the Italian spoken by these “future citizens” have?  This observational study focused on some foreign 5-year-old children in Italian preschools and attempted to describe the language used by these second-generation speakers, between hesitations, silences, achievements and linguistic creativity.

  11. Lo spazio della ricerca nell'area kushi (Nigeria: lingua, comunità e documentazione

    Gian Claudio Batic

    2017-12-01

    Full Text Available There are two questions that fieldwork researchers committed to the documentation and description of a minority language ask themselves before venturing into the depth of their projects: 'Whom am I dealing with?', immediately followed by 'Where am I?'. As trivial as they might appear, these two questions require a minimum of research to produce an answer able to define - without necessarily framing it - the target community and the role a researcher can play in it. This paper focuses on the case study of the Kushi, a Chadic speaking group of north-eastern Nigeria. 'People' and 'space' are analysed from a sociology-of-language perspective as well as in terms of a more general dynamics of migrations and composite societal formations.

  12. Importanza della diversità diatopica nell’insegnamento della lingua spagnola come L2

    Silvia Lafuente

    2013-03-01

    Full Text Available The syncretic cultural identity, in which the Spanish language and its linguistic hegemony are grounded and have reflected its political hegemony, led Spain to take on a predominant role in standardization over the centuries. However, the present situation of the Spanish language is characterized by pluricentrism covering the vast territory in which the language is spoken. This means that a number of cen- ters have set up prestigious standard models providing norms for a country or region. Therefore, a fair enactment of this polycentrism requires national norms, different ways of codification of the Spanish language, answers to geographical and social forms which have split after a common departure and the idea that the varieties of the Spanish language fulfill speakers’ different expressive requirements and help to enhance national identities, in the face of the domination of the peninsular model. This point of view must guide linguistic research, methodology in lexicography, school grammar, translation of foreign languages and especially the teaching of Spanish as L2.

MÉTODOS: Utilizou-se metodologia proposta pela Organização Mundial da Saúde (WHOQOL-BREF e WHOQOL-DIS para a construção dos instrumentos adaptados para população surda em Língua Brasileira de Sinais (Libras. A pesquisa para execução do instrumento consistiu de 13 etapas: 1 criação do sinal qualidade de vida; 2 desenvolvimento das escalas de respostas em Libras; 3 tradução por um grupo bilíngue; 4 versão reconciliadora; 5 primeira retrotradução; 6 produção da versão em Libras a ser disponibilizada aos grupos focais; 7 realização dos grupos focais; 8 revisão por um grupo monolíngue; 9 revisão pelo grupo bilíngue; 10 análise sintática/semântica e segunda retrotradução; 11 reavaliação da retrotradução pelo grupo bilíngue; 12 filmagem da versão para o software; 13 desenvolvimento do software WHOQOL-BREF e WHOQOL-DIS em Libras. RESULTADOS: Características peculiares da cultura da população surda apontaram a necessidade de adaptações na metodologia de aplicação de grupos focais quando compostos por pessoas surdas. As convenções ortográficas da escrita das línguas sinalizadas não estão consolidadas, o que trouxe dificuldades em registrar graficamente as etapas de tradução. As estruturas linguísticas que causaram maiores problemas de tradução foram as que incluíram expressões idiomáticas do português, muitas sem conceitos equivalentes entre o português e a Libras. Foi possível construir um software do WHOQOL-BREF e WHOQOL-DIS em Libras. CONCLUSÕES: O WHOQOL-BREF e o WHOQOL-DIS em Libras possibilitarão que os surdos se expressem autonomamente quanto a sua qualidade de vida, o que permitirá investigar com maior precisão essas questões.

  16. Asimmetrie L1/L2: una sfida nella didattica di “lingua e traduzione”.

    Laura Salmon

    2004-12-01

    Full Text Available Asymmetries Between L1 and L2: a Challenge in the Teaching of "Language and Translation" Language teaching is deeply connected to the cognitive and brain sciences. The attribution of meaning of linguistic messages depends on the interaction between the communicant’s brain and the external world. The interaction is based on the cognitive and emotional experience shared by a L-community. Competence in L2 is acquired by the development of an internal data base of contextualised .units of living speech. (Lurija 1976. L2 teaching is particularly successful when the L2 units are inscribed in memory by means of the functionally equivalent L1 units. Selection of the L1/L2 correspondent units is due to the principle of markedness: each unit of L1 has a functional equivalent in one and only one unit of the L2. Because of the interlingual asymmetries (a set of Italian/Russian examples is given, functional equivalence differs from morphosyntactic and lexical equivalence. The competency in ascribing a degree of markedness to each linguistic unit needs the regular implicit acquisition of the L2 intonational and prosodic system; the processes of the metalinguistic conscious reflection are instead a .hindrance. to the procedural acting of a “living speaker”.

By leading aforementionedassumptions, in this study, most frequently used fifty verbs in Turkishand German will be classified according to statement-action theory andcompared in terms of lingua-structure and culture. Through thecomparison based on frequency and statement-action theory, this studyaims to make inferences that will probably contribute to both teachingGerman to Turkish speaker as a foreign language and teaching Turkishto German speaker as a foreign language.

Os dados apontam que, mesmo com a colonização marcante europeia e a imposição e continuidade da língua castelhana, atualmente a língua Quéchua é considerada como a língua nativa mais falada na América Espanhola; ela sobreviveu e se preservou até os dias de hoje por meio da promulgação de leis de sua preservação. Ela é reconhecida em mídias impressas e televisivas, e no contexto educacional e político. Esse processo de preservação e conhecimento da língua dos seus ancestrais proporcionou uma integração dos povos de origem inca com suas raízes culturais.

  7. ULF/ELF electromagnetic waves associated with the quasi-perpendicular earth's bow shock crossings

    Nozdrachev, M.N.; Petrukovich, A.A.

    1992-01-01

    The present paper is dedicated to the analysis of electromagnetic turbulence in the frequency range 0.1-75 Hz, associated with crossing of Earth's Bow Shock recorded by the Prognoz-8 and -10 satellites. The quasimonochromatic waves are identified in the shock transition region. Their frequencies, laying in the range from 2 Hz to 6 Hz upstream the shock ramp shift to the values less than 1 Hz in the downstream region. The amplitudes of these narrow emissions are high enough to provide the dissipation in the flow of the solar wind plasma. It is argued that spectra shapes in this frequency range 0.1-75 Hz are strongly affected by the Doppler shift

  10. Current densities in a pregnant woman model induced by simultaneous ELF electric and magnetic field exposure

    Cech, R; Leitgeb, N; Pediaditis, M

    2008-01-01

    The pregnant woman model SILVY was studied to ascertain to what extent the electric current densities induced by 50 Hz homogeneous electric and magnetic fields increase in the case of simultaneous exposure. By vectorial addition of the electric current densities, it could be shown that under worst case conditions the basic restrictions recommended by ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines are exceeded within the central nervous system (CNS) of the mother, whereas in sole field exposure they are not. However, within the foetus the induced current densities do not comply with basic restrictions, either from single reference-level electric fields or from simultaneous exposure to electric and magnetic fields. Basic limits were considerably exceeded

  11. Electromagnetic field measurements in ULF-ELF-VLF [0.001 Hz─100 KHz] bands

    C. Di Lorenzo

    2008-01-01

    Full Text Available We are reporting the technological and scientific objectives of the MEM project. The MEM project has been activated in the INGV Observatory of L'Aquila to create in Central Italy a network of observatories in order to monitoring the electromagnetic signals in the frequency band [0.001 Hz–100 kHz]. Some examples of the instrumentation developed in the frame of the project are reported. An innovative technique, based on the wide band interferometry is proposed to obtain detailed information concerning the several detected electromagnetic sources. Moreover, data from each station will be elaborated to investigate different sectors as the structure of ground electric conductibility, the electromagnetic phenomena connected with seismic activity, the separation of the electromagnetic fields originated in the Earth's interior and the electromagnetic phenomena originated in the magnetosphere, in the ionosphere and in the Earth-ionosphere cavity.

  12. ELF whistler events with a reduced intensity observed by the DEMETER spacecraft

    Zahlava, J.; Nemec, F.; Santolik, O.; Kolmasova, I.; Parrot, M.

    2017-12-01

    A survey of VLF frequency-time spectrograms obtained by the DEMETER spacecraft (2004-2010, altitude about 700 km) revealed that the intensity of fractional hop whistlers is sometimes significantly reduced at specific frequencies. These frequencies are typically above about 3.4 kHz (second cutoff frequency of the Earth-ionosphere waveguide), and they vary smoothly in time. The events were explained by the wave propagation in the Earth-ionosphere waveguide, and a resulting interference of the first few waveguide modes. We analyze the events whose frequency-time structure is rather similar, but at frequencies below 1 kHz. Altogether, 284 events are identified during the periods with active Burst mode, when high resolution data are measured by DEMETER. The vast majority of events (93%) occurs during the nighttime. All six electromagnetic field components are available, which allows us to perform a detailed wave analysis. An overview of the properties of these events is presented, and their possible origin is discussed.

  13. ELF field in the proximity of complex power line configuration measurement procedures

    Benes, M.; Comelli, M.; Villalta, R.

    2006-01-01

    The issue of how to measure magnetic induction fields generated by various power line configurations, when there are several power lines that run across the same exposure area, has become a matter of interest and study within the Regional Environment Protection Agency of Friuli Venezia Giulia. In classifying the various power line typologies the definition of double circuit line was given: in this instance the magnetic field is determined by knowing the electrical and geometric parameters of the line. In the case of independent lines instead, the field is undetermined. It is therefore pointed out how, in the latter case, extracting projected information from a set of measurements of the magnetic field alone is impossible. Making measurements throughout the territory of service has in several cases offered the opportunity to define standard operational procedures. (authors)

  3. Rojas Zorrilla y otros dramaturgos españoles en la biblioteca de un sefardí de Gibraltar del siglo XVIII

    Díaz-Mas, Paloma

    2007-06-01

    Full Text Available The manuscript Ms 22090 preserved in the National Library in Madrid is the Cancionero de Abraham Israel, a collection of poems and songs in Spanish, English and lingua franca collected by a Sephardic Jew of Gibraltar from 1761 to 1770. The manuscript also included under the title «Notta de las comedias que tengo en libros» (‘list of the plays I have in books’, a small list of 36 titles of 17th Century Spanish plays, one of whose is Rojas Zorrilla’s Progne y Filomena. The aim of this article is to identify the plays cited in that list, paying special attention to the editions along the 18th century, and to analize how Jews of Gibraltar become from early times a link between Spanish modern culture and Sephardic Jews settled in Morocco, and contributed to the re-hispanization of Morrocan Sephardic language and culture that reach its highest point in the 20th century.El manuscrito Ms 22090 de la Biblioteca Nacional de Madrid es el Cancionero de Abraham Israel, una colección de poemas y canciones en español, inglés y lingua franca recogidos por un sefardí de Gibraltar desde 1761 hasta 1770. En el manuscrito se incluye también, bajo el título «Notta de las comedias que tengo en libros» una breve lista de 36 titulos de obras teatrales españolas del siglo XVII, entre ellas Progne y Filomena, de Rojas Zorrilla. En este artículo identificamos las obras mencionadas en esa lista, con especial atención a las ediciones sueltas impresas en el siglo XVIII, y analizamos cómo los judíos de Gibraltar se convirtieron desde época temprana en un puente entre la cultura española peninsular moderna y la de los sefardíes de Marruecos, lo cual contribuyó a la rehispanización de la lengua y la cultura de los sefardíes marroquíes, que culminó en el siglo XX.

  4. Thirty Years After Bill 101: A Contemporary Perspective on Attitudes Towards English and French in Montreal

    Ruth Kircher

    2014-06-01

    Full Text Available Abstract This paper presents a 2007 study that was conducted amongst 147 young anglophone, francophone and allophone Montrealers in order to shed light on their attitudes towards English and French in terms of status and solidarity. The study made use of both a questionnaire and a matched-guise experiment. The findings indicate that while a certain amount of status was attributed to French, most likely as a result of language policy and planning measures such as Bill 101, significantly more status was attributed to English—most likely a result of the utilitarian value that the language holds as the global lingua franca. Regarding the solidarity dimension, it appears that while the respondents recognised the social desirability of having an affective attachment to the French language, at a more private level, they held more positive attitudes towards English. These can tentatively be explained in terms of the respondents’ social identity. Résumé L’article ci-dessous présente une recherche menée en 2007 parmi 147 étudiants montréalais (anglophones, francophones et allophones qui eut pour objectif d’examiner leurs attitudes envers l’anglais comparé au français en terme de statut et de solidarité. Un questionnaire et une étude des faux-couples furent utilisés comme méthodes de recherche. Les résultats indiquent qu’un certain statut est attribué au français, ce qui est probablement une conséquence des lois langagières comme la Loi 101. Néanmoins, un statut plus important est attribué à l’anglais, ce qui est probablement une conséquence de sa valeur utilitaire comme lingua franca globale. En ce qui concerne la dimension de la solidarité, bien que les jeunes montréalais semblent conscients de l’importance sociale de se sentir attachés à la langue française, lorsque l’on considère un aspect plus personnel, ils tendent à manifester des attitudes plus positives envers l’anglais. Ces attitudes plus positives

  5. La globalización de la lengua inglesa y los estudios postcoloniales

    Ana María FRAILE MARCOS

    2009-11-01

    Full Text Available RESUMEN: Este artículo parte de la premisa de que la expansión de la lengua inglesa por el mundo y su aceptación actual como lingua franca se deben, por una parte, al impacto del Imperio Británico en todos los continentes a partir del siglo XVI y hasta comienzos del XX, y, por otra, al dominio económico, cultural y militar de los Estados Unidos a lo largo del siglo XX y hasta nuestros días. Así pues, la lengua inglesa aparece estrechamente unida al fenómeno colonial e imperialista. Este artículo tratará de exponer, desde un punto de vista literario, el debate abierto dentro de los estudios postcoloniales en torno al uso y cualidad de la lengua inglesa como herramienta literaria y política utilizada por los colonizadores para imponer su autoridad sobre el mundo colonizado y, posteriormente, apropiada y/o rechazada por las culturas postcoloniales en su afán por subvertir la autoridad occidental y reafirmarse en su propia identidad nacional.ABSTRACT: This article is based on the assumption that the expansion of the English language across the world, as well as its current acceptance as a lingua franca, can be traced back both to the impact of the British Empire on all continents since the sixteenth century, and to the economic, military and cultural supremacy of the United States during the twentieth century and up to the present. Hence, a link between the English language and the colonial and imperialist processes is firmly established. This article aims at presenting, from a literary vantage point, the debate originated within the discipline of postcolonial studies concerning the use of the English language as a literary and a political tool, firstly used by the colonizers to impose their authority on the colonized world, and eventually either accepted or rejected by the different postcolonial cultures on their way to self-affirmation and in the search for an authentic national identity.

  12. O galego como lingua de contacto co castelán riopratense: unha relación esquecida

    Carsten Sinner

    2016-01-01

    Full Text Available Unlike contact between Spanish and other languages such as Catalan, contact between Galician and Spanish, two closely related Ibero-Romance languages, has hardly been studied at all. Studies of contact between Galician and American Spanish are rarer still. While contact between Spanish and immigrant languages such as Italian, French, German or even Danish in the Rio de la Plata area and Argentina in particular has been the topic of numerous studies, Spanish-Galician contact is generally ignored. The main focus of the present article is the curious fact that the Galician language has never attracted the attention of Argentinian linguists and scholars in Hispanic Linguistics, not even in the area within the latter dedicated specifically to Argentina’s national language. This fact seems to be related to gen- eral cultural prejudice against Galicians in the Rio de la Plata area. Examples are presented of the influence of Galician on Argentinian Spanish. The article is based on a detailed study of the existing linguistic literature and a number of recent empirical studies in the framework of a research project on language contact among Ibero- -Romance Languages in the Department for Applied Linguistics and Translation Studies at Leipzig University.

    2008-11-01

    Full Text Available Bahasa Indonesia lahir dari Bahasa Melayu yang pada zaman dulu menjadi bahasa lingua franca, yakni bagasa perdagangan antarpulau di nusantara. Kemudian dikukuhkan menjadi bahasa persatuan melalui momen Sumpah Pemuda. Bahasa Melayu menjadi dominan di kala itu dikarenakan fleksibelitasnya akan bahasa-bahasa lain. Dengan fakta tersebut, tepatnya 28 Oktober 1928, bahasa Melayu diangkat sebagai bahasa persatuan dan tahun 1945 diresmikan sebagai bahasa negara. Permasalahan yang muncul dalam eksistensi bahasa Indonesia adalah bagaimanakah cara mempertahankan eksistensi bahasa Indonesia? Tidak hanya masalah eksistensi saja, tetapi sanggupkah bahasa-bahasa daerah di negeri ini memperkaya kosa kata dan istilah bahasa Indonesia? Selain itu, bagaimanakah potensi bahasa Indonesia di era globalisasi? Eksistensi bahasa Indonesia, selain dipengaruhi kekonsistenan penggunaanya, juga didukung oleh kemampuan bahasa tersebut dalam mengungkapkan fenomena baru yang berkembang. Oleh karena itu, perkembangan bahasa Indonesia sangat tergantung pada tingkat keberhasilan menciptakan kosa kata dan istilah-istilah baru. Bahasa Indonesia sudah mulai mengglobal karena bahasa Indonesia memiliki sifat terbuka dan demokratis. Perkembangan yang terjadi sekarang dan yang datang tidak hanya menyangkut masalah struktur dan bahasa, tetapi lebih jauh mengungkapkan permasalahan manusia baru yang dialami manusia di dalam sebuah proses perubahan dalam berbagai aspek kehidupan

  15. Linguistic Justice for which Demos? The Democratic Legitimacy of Language Regime Choices

    Garcia Núria

    2016-10-01

    Full Text Available In the European Union language regime debate, theorists of multiculturalism and cosmopolitanism have framed their arguments in reference to different theories of justice and democracy. Philippe Van Parijs advocates the diffusion of a lingua franca, namely English, as means of changing the scale of the justificatory community to the European level and allowing the creation of a transnational demos. Paradoxically, one key dimension of democracy has hardly been addressed in this discussion: the question of the democratic legitimacy of language regime choices and citizens’ preferences on the different language regime scenarios. Addressing the question of the congruence of language policy choices operated by national and European elites and ordinary citizens’ preferences, this paper argues first that the dimension of democratic legitimacy is crucial and needs to be taken into account in discussions around linguistic justice. Criticizing the assumption of a direct correspondence between individuals’ language learning choices and citizens’ language regime preferences made by different authors, the analysis shows the ambivalence of citizens’ preferences measured by survey data. The article secondly raises the question of the boundaries of the political community at which the expression of citizens’ preferences should be measured and demonstrates that the outcome and the fairness of territorial linguistic regimes may vary significantly according to the level at which this democratic legitimacy is taken into account.

The following issues are critically discussed: homophobia regarding sexual minorities, a lack of sensitivity for the negative effects of male domination and the objection to English as the lingua franca for teaching. These aspects are assessed against the background of the Derridean notion of ‘deconstruction’ and the contributions of the first professors employed in the Faculty of Theology since its inception in 2017.

    Full Text Available Professional multilingual environments using English as a lingua franca are prone to imbalances in communication, linguistic insecurity and rising tension. Non-native English speakers develop avoidance strategies in order to lessen their apprehension. To overcome these imbalances, this research aims to understand the relationships formed around languages focusing on the dynamics of integration and the requests for help. Guided by the actantial models of Greimas (1966, this qualitative study employs semiolinguistics and discourse analysis, including 19 narrative interviews with employees of Airbus and UNESCO in Hamburg, Germany in 2013. This methodology draws on actors connected through relationships of power and/or collaboration. The actantial models applied seek linguistic input through designational paradigms, shifters and modal occurrences. The actantial models illustrate how a good language competence provides a better understanding of one’s direct as well as passive environment. The learning process is shown to be a conduit to integration. The actantial model and discourse analysis shed light on the complex situation of multilingual communication settings by highlighting the influence of individuals’ linguistic skills. As a matter of fact, depending on the role of each individual in a given situation, lending a helping hand sometimes equates to upsetting the balance.

    Full Text Available Notwithstanding the substantial transformation of education in South Africa in the last 20 years, specifically to redress the past inequalities, the challenges are ongoing. These challenges include tertiary institutions having to accommodate a culturally and linguistically diverse group of students, often second-language (L2 English speakers, in an English lingua franca classroom. This study investigated the reading attitudes and habits of students in an intermediary programme of a tertiary institution and any perceived changes to these attitudes or habits, as well as their perceptions of the promotion of reading by the programme. On successful completion of the intermediary programme, students register for the compulsory first-year English distance learning course and are required to complete a placement test. Results for students who attended the intermediary programme were compared with those of students who did not attend the intermediary programme but registered directly for mainstream. The teaching of reading appeared invaluable at the tertiary level with the indication that students’ attitudes and behaviour changed and that they inter alia realised the academic value thereof, made decisions to take up reading as a hobby and discovered new genres.
