Korpusa datu izmantošana mūsdienu mācību vārdnīcās angļu valodā
2018
Mūsdienu leksikogrāfijā liela nozīme tiek piešķirta dažādiem korpusa izmantošanas paņēmieniem. Korpuss atklāj raksturīgākās valodas iezīmes un sniedz informāciju par noteiktu vārdu un frāžu leksiskajām pazīmēm. Bakalaura darbā pētīta korpusa datu izmantošana Longman, Oxford un Macmillan mācību vārdnīcās angļu valodā. Salīdzinošā analīze tika pielietota, lai salīdzinātu korpusa datu izmantošanu izvēlētajās vārdnīcās. Pētījuma rezultāti norādīja, ka korpusa datu izmantošana izvēlētajās vārdnīcās atšķiras diezgan pamanāmi, papildus tam rezultāti pierādīja, ka korpuss ir neaizstājama mūsdienu leksikogrāfijas sastāvdaļa. Tā kā pētījumam tika izvēlētas tikai trīs mācību vārdnīcas, ir ieteicams ve…
Sintesi, caratterizzazione e studio dell'attività biologica di nuovi complessi mononucleari di PT(II) con leganti eterociclici
2008
Sono stati precedentemente sintetizzati complessi mono- e polinucleari di Pt(II) [1, 2] che hanno mostrato attività citotossica maggiore del cisplatino. Tre nuovi complessi mononucleari di Pt(II) analoghi del cisplatino sono stati quindi in seguito preparati usando leganti eterociclici quali: 5,6-difenil-3-(2-piridil)-1,2,4-triazina-4’,4’’-disulfonato sodico (dptdn), 5,6-difenil-3-(2-piridil)-1,2,4-triazina (dpt) e 2,6-bis(2-benzimidazolil)piridina (bbp). I risultanti tre complessi [PtCl(bbp)]Cl (1), [PtCl2(dptdn)](H2O) (2) e [(dptdn)(dpt)Pt]Cl2(H2O) (3), ionici (1) e (3) e neutro (2), sono stati sintetizzati e strutturalmente caratterizzati tramite spettroscopia IR e NMR 1D e 2D 1H e 13C. …
Application d’un modèle conceptuel à l’analyse de la dynamique hydrométéorologique des crues dans un bassin-versant en milieu tropical humide : cas d…
2015
7 pages; International audience; Application of a conceptual model to analysis of dynamic hydrometeorological flood in a pool - side in tropicalmoist environment : the case of Mono river. The objective of this study is to analyze the dynamics of the basinhydrometeorological and distribution of incoming flood dam Nangbéto to assess the risk of flooding in the lower valley of theriver. The data used are: daily flows of Mono (m3.s-1) and Nangbéto Athiémé, evapotranspiration (mm / day, calculatedaccording to the method Oudin et al., 2005) and the average precipitation over the basin (mm / day) covering the period1988- 2010. The method of spatial interpolation of rainfall tested is that of ordin…
Concordant Intestinal Atresia in Two Pairs of Monozygotic Twins
2011
Intestinal atresia in both twins from the same pregnancy is very rare. Only seven pairs of twins have been described. The authors report on two cases of monozygotic twins with different types of intestinal atresia and clinical evolution. Both pairs of observed twins turned out to be concordant for the presence of intestinal malformations and for the absence of other linked malformations; nevertheless, the atresic lesions were anatomically discordant in each pair of monozygotic twins. Therefore, the diagnostic and therapeutic procedures have shown some differences in phenotypic expression between the twins of both pairs. Possible etiologic factors and pathogenetic pathways are discussed, and…
Probabilistic Logic under Coherence: Complexity and Algorithms
2005
In previous work [V. Biazzo, A. Gilio, T. Lukasiewicz and G. Sanfilippo, Probabilistic logic under coherence, model-theoretic probabilistic logic, and default reasoning in System P, Journal of Applied Non-Classical Logics 12(2) (2002) 189---213.], we have explored the relationship between probabilistic reasoning under coherence and model-theoretic probabilistic reasoning. In particular, we have shown that the notions of g-coherence and of g-coherent entailment in probabilistic reasoning under coherence can be expressed by combining notions in model-theoretic probabilistic reasoning with concepts from default reasoning. In this paper, we continue this line of research. Based on the above sem…
Conformational investigation of α,β‐dehydropeptides Part VI. Molecular and crystal structure of benzyloxycarbonylglycyl‐(Z )‐dehydrophenylalanine
1994
The structure of a peptide containing C-terminal dehydrophenylalanine, Z-Gly-(Z)-delta Phe (C19H18N2O5, MW = 354) was determined from single-crystal X-ray diffraction data. Needle-shaped crystals were grown from a 1:1 mixture of methanol-acetone in the monoclinic space group P2(1) with a = 14.717(4), b = 4.941(2), c = 12.073(4) A, beta = 103.72(4) degrees; V = 852.86(8) A3, Z = 2 and Dc = 1.32 g cm-3. The structure was solved by direct methods using SHELXS-86 and refined to a final R-index of 0.032 for 1714 observed reflections. The peptide adopts a conformation folded at the glycine residue, and principal torsion angles are omega 0 = -167.6(2) degrees, phi 1 = -71.8(3) degrees, psi 1 = -31…
A Uniform Conspiracy Mindset or Differentiated Reactions to Specific Conspiracy Beliefs? Evidence From Latent Profile Analyses
2021
Conspiracy theories arise for virtually any public event (e.g., pandemics, assassinations, disasters). In light of positively correlated endorsements of such beliefs, many have pointed to a more general mindset behind this. Others have argued against this notion of a consistent mindset. Applying Latent Profile Analyses, we examine the evidence for either uniform or differentiated response patterns to various items in five studies (reanalyzed datasets, total N = 7877). Overall, the results speak strongly to uniform reactions that could be summarized as a general mindset, but also revealed important qualifications. First, small parts of the samples show more differentiated patterns in relatio…
L’evoluzione del formalismo negoziale nei contratti bancari e finanziari
2022
Il lavoro traccia le principali linee evolutive in tema di forma dei contratti bancari e finanziari, concentrandosi sui più recenti orientamenti della Corte di cassazione italiana. Si evidenzia, quindi, un progressivo cambio di atteggiamento della giurisprudenza volto a mitigare la rigidità dei vincoli formali interpretandoli in chiave funzionale.
Application of Silsesquioxanes in the Preparation of Polyolefin-Based Materials
2023
This paper is a review of studies on the use of the polyhedral oligomeric silsesquioxanes (POSS) of various structures in the synthesis of polyolefins and the modification of their properties, namely: (1) components of organometallic catalytic systems for the polymerization of olefins, (2) comonomers in the copolymerization with ethylene, and (3) fillers in composites based on polyolefins. In addition, studies on the use of new silicon compounds, i.e., siloxane–silsesquioxane resins, as fillers for composites based on polyolefins are presented. The authors dedicate this paper to Professor Bogdan Marciniec on the occasion of his jubilee.
Copolymerization of Ethylene with Selected Vinyl Monomers Catalyzed by Group 4 Metal and Vanadium Complexes with Multidentate Ligands: A Short Review
2021
This paper gives a short overview of homogeneous post-metallocene catalysts based on group 4 metal and vanadium complexes bearing multidentate ligands. It summarizes the catalytic behavior of those catalysts in copolymerization of ethylene with 1-olefins, with styrenic monomers and with α,ω-alkenols. The review is focused on finding correlations between the structure of a complex, its catalyst activity and comonomer incorporation ability, as well as the microstructure of the copolymer chains.
