THE INTERPLAY OF PROPOSITIONAL AND COMMUNICATIVE INFORMATION IN SENTENCE SYNTHESIS

The paper explores the interplay of the propositional (situational, “objective”) and communicative (information packaging) aspects of sentence meaning by looking into ways in which the values of semantic-communicative oppositions such as Thematicity, Focalization, Assertivity, etc., influence the expression of propositional content

Un dictionnaire de reformulation pour les apprenants du français langue seconde

Nous présentons une recherche en lexicologie appliquée à l’enseignement du français langue seconde qui vise le développement d’un dictionnaire électronique de type particulier, appelé dictionnaire de reformulation. Ce dictionnaire devrait permettre aux étudiants de niveau intermédiaire à ceux de niveau avancé de surmonter des difficultés que présente une utilisation souple et idiomatique du lexique du français dans la production langagière. Les questions abordées sont les suivantes : les fondements théoriques et la méthodologie pour l’élaboration d’un tel dictionnaire, le concept d’erreur lexicale et la description des erreurs lexicales à l’aide d’outils formels que nous proposons, l’architecture du dictionnaire de reformulation et l’implémentation de ce dernier. Le cadre théorique dans lequel se situe notre recherche est celui de la théorie linguistique Sens-Texte.This paper describes a research project in lexicology applied to the teaching of French as a second language, which aims at developing an electronic dictionary of a particular type called a reformulation dictionary. This dictionary should enable intermediate-to-advanced level students to overcome difficulties in using the French lexicon in a flexible and idiomatic way when performing language production tasks. The following questions are addressed : the theoretical bases and the methodology for the development of a reformulation dictionary, the concept of lexical error and the description of lexical errors with the aid of formal tools that we suggest, and the overall design and the implementation of our reformulation dictionary. The theoretical framework for this research is Meaning-Text linguistic theory

Combien d’acceptions le mot keuz ‘regret’ a-t-il ?

Nous présentons dans cet article les critères permettant de distinguer les différentes acceptions d’un mot polysémique. Ce travail préalable de distinction – nous parlons de lexémisation – est indispensable à la description du mot dans le dictionnaire. Nous prenons comme exemple le mot polysémique breton vannetais keuz ‘regret’ parce que d’une part, les acceptions de keuz présentent de notables différences avec leurs équivalents français et que, d’autre part, le vannetais connaît tout un groupe d’acceptions qui sont inconnues, semble-t-il, en breton KLT et n’ont pas d’équivalents en français. Notre cadre théorique est la théorie Sens-Texte.In this article, we present the criteria for distinguishing the different meanings of a polysemous word. This preliminary differentiation process – or lexemisation – is essential for compiling a description of a word in a dictionary. We use as an example the polysemous Vannetais word keuz ‘regret’, because, on the one hand, its meanings differ significantly from their French equivalents and, on the other, Vannetais has a whole group of meanings that have no French equivalents and that seem to be unknown in KLT Breton. Our theoretical framework is the Meaning-Text theory

The ability of fungus mucor racemosus fresenius to degrade high concentration of detergent

©2014 CI and CEQ. All rights reserved. The ability of fungus Mucor racemosus Fresenius to decompose high concentration of commercial detergent (Merix, Henkel, Serbia) was investigated in this study. Fungus was cultivated in liquid growth medium by Czapek with addition of detergent at concentration 0.5% during 16 days. The biochemical changes of pH, redox potential, amount of free and total organic acids, and activity of alkaline phosphatase were evaluated by analysis of fermentation broth. Simultaneously, biodegradation percentage of anionic surfactant of tested detergent was confirmed by MBAS assay. At the same time, the influence of detergent on fungal growth and total dry weight biomass was determined. Detergent addition at concentration 0.5% resulted in a decrease in pH value and increase in redox potential as well as increase of free and total organic acids. Enzyme activity of alkaline phosphatase was reduced by detergent at concentration 0.5%. The fungus was decomposed about 62% of anionic surfactant during 16 day. Due to the fungus, higher dry weight biomass (53%) was produced compared to the control

The effects of detergent, sodium tripoly-phosphate and ethoxyled oleyl-cetyl alcohol on metabolic parameters of the fungus trichothecium roseum link

The degradation of detergents that are dispersed in water and soil partially depends on the metabolic activities of fungi. Among the fungi that have this ability, Deuteromycetes are particularly noted for their biochemical characteristics. Taking this into account, it was of interest to analyze the influence of detergent and its main compounds, ethoxyled oleylcetyl alcohol (AOC) and sodium tripoly-phosphate (TTP), on the metabolism of the fungus Trichothecium roseum. Our results revealed that both detergent and AOC had an inhibitory effect on the bioproduction of free organic acids, while TTP stimulated their production. Also, detergent inhibited the bioproduction of basic amino acids, with the exception of alanine. In addition, detergent applied at 1% concentration inhibited the bioproduction of proteins and the total biomass of the fungus, while AOC and TTP inhibited the production of proteins, but stimulatedl the production of Trichothecium

A LIVEBORN INFANT WITH TRIPLOIDY 69,XXX: CASE REPORT

Since liveborn babies with triploidy are quite rare, we report here a new case of a liveborn female baby, with a karyotype 69,XXX. Ultrasound examination of the fetus, in the 37th week (9th month) of uncontrolled pregnancy, discovered severe intrauterine growth restriction and olygoamnion. A sample of fetal blood was taken by cordocentesis, in order to analyze fetal chromosomes. Two days later, the liveborn child was delivered by Cesarean section and died the same day, 7 hours and 55 minutes later, due to respiratory insufficiency. Autopsy revealed deformity of the joints, ectrodactyly of feet, deformity of the face (large, low positioned ears, hypotelorism and hypoplastic mandibula), with irregular position of both hands, hypoplastic lungs, kidneys, suprarenal glands, gallbladder and thymus agenesis. Chromosome analysis performed from fetal blood lymphocytes taken by cordocentesis showed karyotype 69,XXX. We would like to emphasize the significance of a health education of pregnant women, in order to establish regular examinations, and thus improve diagnostic and disease management possibilities.Key words: Triploidy, multiple anomalies, cordocentesi

Uticaj masti u obroku na masne kiseline u serumskim fosfolipidima i gojaznost životinja

Dietary fat and its relation to obesity has been a controversial issue for many years. Experimental data shows that most, though not all animals, which consume a high fat diet, will become obese. However, the effect of fatty acids on animal obesity has not been studied in detail. In order to evaluate the effects of low versus high fat diet on serum phospholipids fatty acids composition a 4-wk study was conducted on male Wister rats. The rats were fed low-fat (10% energy) and high-fat (46% energy) foods containing constant proportions of fatty acids. Control group C was fed a standard laboratory diet (polyunsaturated/ saturated (P/S) fatty ratio 1.3), group M was fed a standard laboratory diet supplemented with margarine (P/S ratio 0.95), and the diet of the SL group was additionally supplemented with a sunflower oil-lard (1:1) mixture (P/S ratio 1.3). All lipid supplemented hyperenergetic diets caused an increase in the average daily energy intake. Both the final and the daily body weight gain were significantly higher in M and SL groups than in group C. Additionally, serum triglyceride levels, LDL-cholesterol and total cholesterol were also significantly higher in M and SL groups when compared to the control group. Serum phospholipids fatty acids varied in response to total dietary fat. A significant decrease in saturated fatty acids (SFA) content (16:0 and 18:0) and an increase in monounsaturated fatty acid (MUFA) content (18:1, n-9) was found in the M group when compared to both C and SL groups. In the SL group, SFA content (18:0) was higher and MUFA content (18:1, n-9) was lower than in group C. Polyunsaturated fatty acids (PUFA) content showed an increase in both experimental groups. The PUFA/SFA ratio was higher in the M group than in the C and SL groups. Our study suggests that the amount of dietary fat has a greater influence on obesity than the effects of the type of fat consumed. However, depending on the type of fat present in the diet the differences were observed in the composition of serum PL fatty acid suggesting that both total fat and individual fatty acids have to be considered when reaching conclusions about the effect of dietary fat and obesity in animals.Uticaj masnih kiselina u ishrani i njihov efekat na pojavu gojaznosti kod životinja je kontraverzno pitanje već dugi niz godina. Uticaj pojedinačnih masnih kiselina na pojavu gojaznosti kod životinja nije do sada detaljnije proučavan. Sa ciljem da se ispita efekat dijeta sa niskim ili visokim sadržajem masti na pojavu gojaznosti, izvršena su istraživanja na Wister pacovima u trajanju od 4 nedelje. Pacovi su hranjeni eksperimentalnim dijetama koje su sadržale standardan, nizak (10%) ili visok (46%) energetski unos poreklom od masti. Grupa kontrolnih životinja (C) je hranjena standardnom laboratorijskom dijetom (odnos polizasićenih/ zasićenih masnih kiselina/PUFA, P/S 1.3), grupa M sa standardnom dijetom sa dodatkom margarina (P/S 0.95) i grupa SL sa dijetom kojoj je dodata mešavina 1:1 suncokretovog ulja i masti (odnos P/S 1.3). Obe dijete (M i SL) su uzrokovale povećanje u prosečnom dnevnom energetskom unosu. U grupi M i SL, registrovano je značajno povećanje u telesnoj težini kontinuirano tokom eksperimenta. Nivo serumskih triglicerida, LDL kao i ukupnog holesterola su bili značajnije povećani u M i SL grupi u poređenju sa kontrolom. Promene u profilu serumskih masnih kiselina fosfolipida su zavisile od sastava masti u eksperimentalnoj dijeti. Kod eksperimentalnih životinja grupe M primećeno je značajno smanjene serumskih zasićenih masnih kiselina (SFA, 16:0 i 18:0) kao i porast monozasićenih masnih kiselina (MUFA, 18:1, n-9) u poređenju sa SL i C grupom. Odnos PUFA/ SFA je bio veći u M u odnosu na SL i C grupu. Rezultati naših istraživanja ukazuju da količina masti u ishrani životinja ima veći uticaj na porast telesne mase nego vrsta prisutne masnoće. Promene u sastavu serumskih masnih kiselina fosfolipida u odnosu na tip masti u eksperimentalnim dijetama ukazuju na ulogu pojedinačnih masnih kiselina u procesu nastajanja gojaznosti kod životinja i te mehanizme treba dalje istraživati

Plagiarism meets paraphrasing: insights for the next generation in automatic plagiarism detection

[EN] Although paraphrasing is the linguistic mechanism underlying many plagiarism cases, little attention has been paid to its analysis in the framework of automatic plagiarism detection. Therefore, state-of-the-art plagiarism detectors find it difficult to detect cases of paraphrase plagiarism. In this article, we analyze the relationship between paraphrasing and plagiarism, paying special attention to which paraphrase phenomena underlie acts of plagiarism and which of them are detected by plagiarism detection systems. With this aim in mind, we created the P4P corpus, a new resource that uses a paraphrase typology to annotate a subset of the PAN-PC-10 corpus for automatic plagiarism detection. The results of the Second International Competition on Plagiarism Detection were analyzed in the light of this annotation.The presented experiments show that (i) more complex paraphrase phenomena and a high density of paraphrase mechanisms make plagiarism detection more difficult, (ii) lexical substitutions are the paraphrase mechanisms used the most when plagiarizing, and (iii) paraphrase mechanisms tend to shorten the plagiarized text. For the first time, the paraphrase mechanisms behind plagiarism have been analyzed, providing critical insights for the improvement of automatic plagiarism detection systems.We would like to thank the people who participated in the annotation of the P4P corpus, Horacio Rodriguez for his helpful advice as experienced researcher, and the reviewers of this contribution for their valuable comments to improve this article.
