Pour une typologie moderne des dictionnaires
Sündüzztürk Kasar
Synergies Turquie , 2008,
Abstract: Le présent article se propose de faire une typologie moderne des dictionnaires, car la pratique lexicographique ne cesse de se renouveler avec les progrès récents dans les domaines de l’informatique et de la lexicologie. Une classification moderne de dictionnaires pourrait être fondée sur six critères : le mode de présentation ; le matériau de la microstructure ; le nombre et le statut des langue(s) étudiée(s) ; les propriétés des informations fournies ; l’extension de la nomenclature et l’organisation de la macrostructure. Suivant ces six critères, nous distinguons, respectivement, les dictionnaires de divers types : dictionnaires sur papier/dictionnaires électroniques/dictionnaires numériques ; dictionnaires (proprement dits)/dictionnaires illustrés/dictionnaires en images ; dictionnaires monolingues/dictionnaires plurilingues ; dictionnaires de mots ou dictionnaires de langue/dictionnaires de choses ou dictionnaires encyclopédiques ; dictionnaires extensifs/dictionnaires restrictifs et, dernièrement, dictionnaires alphabétiques/dictionnaires thématiques. Nous essayons d’illustrer cette typologie par un tableau qui contient des exemples pour chaque type de dictionnaire.

Abstract: Although rare, heparin-induced thrombocytopenia (HIT) is one of the most feared complications of heparin therapy. It is an antibody-mediated, acquired and transient thrombotic disorder following exposure to heparin. Unfractionated heparin is the standard anticoagulation used in hemodialysis sessions and hemodialysis patients who are continually exposed to heparin are at increased risk for HIT. We report a 75-year-old male patient with acute-on-chronic renal failure who subsequently developed HIT while on hemodialysis. The patient was presented with deep vein thrombosis and successfully treated with fondaparinux. In this report we also review the off-label use of fondaparinux for the treatment and prophylaxis of thrombosis in patients with HIT. As fondaparinux is too small to be recognized by the majority of heparin-reactive antibodies it could be a reasonable alternative anticoagulant for symptomatic HIT patients where licensed drugs like lepirudin and danaparoid are not available

Abstract: The prognosis for the majority of acute myeloid leukemia (AML) patients without a donor is dismal whether conventional salvage chemotherapy regimens or investigational strategies are used, and most of these patients will eventually die of their disease. There is no standard chemotherapy regimen that provides durable complete remission in patients with refractory AML. Beneficial effects of amifostine, either alone or in combination with conventional chemotherapy, was demonstrated in patients with myelodysplastic syndrome and poor prognosis AML. Here we report our second experience with AML patients who were successfully treated with an amifostine containing noncytotoxic drug combination. The beneficial effects of amifostine are not limited to cytoprotectivity which enables doseescalation for many chemotherapeutic agents, at least in some refractory AML it can also be used as a bridge to hematopoietic stem cell transplantation.

Abstract: In the title molecule, C24H28N2O3, the cyclohexene ring is in a sofa conformation and the 1,4-dihydropyridine ring is in a slight boat conformation. In the indole ring system, the pyrrole and benzene rings form a dihedral angle of 2.63 (7)°. In the crystal, N—H...O hydrogen bonds connect the molecules into C(6) chains parallel to the b axis and pairs of weak C—H...O hydrogen bonds link inversion-related chains into a ladder motif through R22(18) rings. A weak intramolecular C—H...O hydrogen bond is also observed.

Abstract: The title compound, C23H25BrN2O3, crystallizes with two independent molecules in the asymmetric unit (Z′ = 2) which differ in the twist of the 5-bromo-1H-indole ring with respect to the plane of the 4-methyl-1,4,5,6,7,8-hexahydroquinoline ring [dihedral angles of 78.55 (9) and 89.70 (8)° in molecules A and B, respectively]. The indole ring is planar in both molecules [maximum deviations = 0.021 (3) and 0.020 (3) for the N atom] while the cyclohexene ring has adopts a sofa conformation. In the crystal, molecules are linked by pairs of N—H...O hydrogen bonds, forming dimers with R12(6) ring motifs. These dimers are connected by N—H...O hydrogen bonds, generating chains along [110]. A C—H...O contact occurs between the independent molecules.

Abstract: a qualified in0.15ga0.85as/gaas superlattice was grown on an n-type gaas(100) substrate by molecular beam epitaxy(mbe). analysis of this structure was first carried out by x-ray diffraction (xrd) and this structure's the interface thicknesses, roughness and x concentration determined at nanoscale. secondly, the electrical characteristics of this sample such as the current-voltage-temperature (i-v-t), capacitance-voltage-temperature (c-v-t) and conductance-voltage temperature (g-v-t) were studied over a wide temperature range. the energy distribution of interface states was determined from the forward bias i-v characteristics by taking into account the bias dependence of the effective barrier height. experimental results show that the forward and reverse i-v characteristics are similar to schottky-junction behavior. the ideality factor n, series resistance rs, barrier height φb and density of interface states nss were found to be strong functions of temperature. according to thermionic emission (te) theory, the zero-bias barrier height (bo) calculated from forward bias i-v characteristics was found to increases with increasing temperature. in addition, the value of rs as a function of both voltage and temperature was obtained from c-v and g-v characteristics. the temperature dependent of i-v, c-v and g-v characteristics confirmed that the distribution the rs and nss are important parameters that influence the electrical characteristics of these devices.

Abstract: the aim of the present study was to evaluate the relationship between salivary oxidative stress and dental-oral health. healthy young adults, matched for gender and age, with (n = 21, 10 men, mean age: 20.3 ± 1 years) and without (n = 16, 8 men, mean age: 21.2 ± 1.8 years) caries were included in this study. the world health organization (who) caries diagnostic criteria were used for determining the decayed, missing, filled teeth (dmft) index. the oral hygiene and gingival status were assessed using the simplified oral hygiene index and gingival index, respectively. unstimulated salivary total protein, glutathione (gsh), lipid peroxidation and total sialic acid levels, carbonic anhydrase activity, and salivary buffering capacity were determined by standard methods. furthermore, salivary ph was measured with ph paper and salivary flow rate was calculated. simplified oral hygiene index and gingival index were not significantly different between groups but dmft scores were significant (p < 0.01). only, gsh values were significantly different (p < 0.05) between groups (2.2 and 1.6 mg/g protein in young adults without caries and with caries, respectively). there was a significant negative correlation between dmft and gsh (r = -0.391; p < 0.05; pearson's correlation coefficient). our results suggest that there is an association between caries history and salivary gsh levels.

In this study, it was to investigate the swelling performance of novel biohybrid composite hydrogel sorbents containing acrylamide/potassium 3-sulfopropyl methacrylate/sodium alginate/bentonite in water and binary mixtures of water-solvent. Novel hydrogels were synthesized with free radical solution polymerization by using ammonium persulfate/N,N,N’,N’-tetramethylethylenediamine as redox initiating pair in presence of poly(ethylene glycol) diacrylate as crosslinker. Swelling experiments were performed in water and binary mixtures of water-solvent (acetone, methanol and tetrahydrofuran) at 25°C, gravimetrically. Some swelling and diffusion properties of the hydrogels were calculated and they were discussed for the biohybrid/hybrid hydrogel systems prepared under various formulations. It has been seen the lower equilibrium percentage swelling ratio values (62% - 124%) in all solvent compositions in comparison with the equilibrium percentage swelling ratio values in water (718% - 2055%). Consequently, the hydrogel systems developed in this study could serve as a potential device for water and water-solvent binary mixtures.
