la lutte contre le blanchiment de capitaux : le banquier entre le principe de non-ingérence et le devoir de vigilance

Les établissements de crédit ont des responsabilités particulières : d’une part, en tant que professionnel averti ; ils ont des obligations vis-à-vis de leur clientèle qui visent spécifiquement à protéger le consommateur partie profane contre d’éventuels abus du professionnel partie initiée. D’autre part, en tant que des acteurs financiers inédits, ces établissements sont dans l’obligation de respecter les normes internationales et les exigences nationales qui régissent ce secteur ; notamment, ils sont astreints au devoir de vigilance qui leur impose d’être diligent et de s’activer efficacement dans la lutte contre le blanchiment de capitaux (LBC) et le financement du terrorisme (FT), afin de s’aligner aux normes internationales et de contourner les sanctions, on peut dire que le banquier est entre l’enclume du principe de non-immixtion dans les affaires de ses clients et la matraque de devoir de vigilance et de diligence en matière de LBC/FT. Toutefois, force est de reconnaitre que le second prime sur le premier

Eucalyptus oleosa Essential Oils: Chemical Composition and Antimicrobial and Antioxidant Activities of the Oils from Different Plant Parts (Stems, Leaves, Flowers and Fruits)

Essential oils obtained by hydrodistillation from the different parts (stems, adult leaves, immature flowers and fruits) of Eucalyptus oleosa were screened for their antioxidant and antimicrobial properties and their chemical composition. According to GC-FID and GC-MS, the principal compound of the stem, immature flowers and the fruit oils was 1,8-cineole, representing 31.5%, 47.0% and 29.1%, respectively. Spathulenol (16.1%) and γ-eudesmol (15.0%) were the two principal compounds of adult leaves oil. In the DPPH (1,1-diphenyl-2-picrylhydrazyl) assay, the oils of the four parts showed moderate antioxidant activity. In the ABTS (2,2’-azinobis-3-ethylbenzothiazoline-6-sulphonate) assay, the most active part was the adult leaves, with a IC50 value 13.0 ± 0.6 mg/L, followed by stems (IC50 = 43.5 ± 1.4 mg/L). The essential oils showed a better antibacterial activity against Gram-positive and Gram-negative bacteria, and a significant antifungal activity also was observed against yeast-like fungi. A strong correlations between oxygenated monoterpenes and antimicrobial activity (especially 1,8-cineole) were noted (R2 = 0.99, 0.97 and 0.79 for B. subtilis, P. aeruginosa and C. albicans, respectively)

Towards the integration of Information and Communication Technologies (ICT) in the Civil Suit

L'institution judiciaire en général et le procès civil en particulier ne sont pas épargnés par le mouvement de la dématérialisation qui touche de nombreux secteurs du service public. En effet, l'introduction des TIC dans le procès civil a été motivée principalement par la quête de la célérité et de l'efficacité de ce dernier. Toutefois, il faudrait contrebalancer ces deux objectifs recherchés avec l'exigence du respect des garanties procédurales et institutionnelles des justiciables. Car, la recherche d'accélération du temps judiciaire et la réalisation d'économie de moyens alloués à ce service ne doivent pas l'emporter sur la qualité des jugements civils. La conciliation de ces trois exigences se révèle comme l'obstacle majeur qui freine le processus d'intégration des TIC dans le procès civil. Néanmoins, tout est question d'équilibre : la technique informatique ne doit pas l'emporter sur la technique juridique et sur l'esprit même de la justice. L'essentiel, c'est que authenticité et modernité riment ensemble.The justice system in general and the civil suit in particular not been spared by the movement of dematerialisation wich has affected many areas of public service. In fact, the introduction of ICT in the civil suit was fueled primarily by the quest for speed and efficiency. However, the need arose to balance these two objectives with the requirement of compliance with procedural and institutional guarantees for a fair trial. This is because the quest to accelerate judicial time and save resources allocated to this service sould not undermine the quality of civil judgments. Reconciling these three requirements is revealed as the major obstacle hindering the process of ICT integration in civil suits. Nevertheless, it is all about balance: computer technology should not prevail over the legal system and the spirit of justice. It is essential the authenticity and modernity go hand in hand

Dempster-Shafer Theory for the Prediction of Auxin-Response Elements (AuxREs) in Plant Genomes

Auxin is a major regulator of plant growth and development; its action involves transcriptional activation. The identification of Auxin-response element (AuxRE) is one of the most important issues to understand the Auxin regulation of gene expression. Over the past few years, a large number of motif identification tools have been developed. Despite these considerable efforts provided by computational biologists, building reliable models to predict regulatory elements has still been a difficult challenge. In this context, we propose in this work a data fusion approach for the prediction of AuxRE. Our method is based on the combined use of Dempster-Shafer evidence theory and fuzzy theory. To evaluate our model, we have scanning the DORNRÖSCHEN promoter by our model. All proven AuxRE present in the promoter has been detected. At the 0.9 threshold we have no false positive. The comparison of the results of our model and some previous motifs finding tools shows that our model can predict AuxRE more successfully than the other tools and produce less false positive. The comparison of the results before and after combination shows the importance of Dempster-Shafer combination in the decrease of false positive and to improve the reliability of prediction. For an overall evaluation we have chosen to present the performance of our approach in comparison with other methods. In fact, the results indicated that the data fusion method has the highest degree of sensitivity (Sn) and Positive Predictive Value (PPV)

Effect of solvent extraction on Tunisian esparto wax composition

The increase of needs for renewable and vegetable based materials will help to drive the market growth of vegetable waxes. Because of their highly variable composition and physicochemical properties, plant waxes have found numerous applications in the: food, cosmetic, candle, coating, polish etc... The aim of this project is to determine the effect of solvent extraction (petroleum ether and ethanol) on Tunisian esparto wax composition. The GC-MS was applied in order to determine the waxes compositions. Then, physicochemical parameters of these two samples of waxes: acid value, saponification value, iodine value and melting point were measured in order to deduct their properties and possible fields of uses. Results showed that esparto wax composition depended on the solvent extraction and that major components of the two samples of waxes were: alkanes, esters of fatty acids and phenols. Furthermore, esparto waxes were characterized by an antioxidant and antibacterial activities but the potential of these activities depended on the solvent of wax extraction

An Evidence Theory and Fuzzy Logic Combined Approach for the Prediction of Potential ARF-Regulated Genes in Quinoa

Quinoa constitutes among the tolerant plants to the challenging and harmful abiotic environmental factors. Quinoa was selected as among the model crops destined for bio-saline agriculture that could contribute to the staple food security for an ever-growing worldwide population under various climate change scenarios. The auxin response factors (ARFs) constitute the main contributors in the plant adaptation to severe environmental conditions. Thus, the determination of the ARF-binding sites represents the major step that could provide promising insights helping in plant breeding programs and improving agronomic traits. Hence, determining the ARF-binding sites is a challenging task, particularly in species with large genome sizes. In this report, we present a data fusion approach based on Dempster–Shafer evidence theory and fuzzy set theory to predict the ARF-binding sites. We then performed an “In-silico” identification of the ARF-binding sites in Chenopodium quinoa. The characterization of some known pathways implicated in the auxin signaling in other higher plants confirms our prediction reliability. Furthermore, several pathways with no or little available information about their functions were identified to play important roles in the adaptation of quinoa to environmental conditions. The predictive auxin response genes associated with the detected ARF-binding sites may certainly help to explore the biological roles of some unknown genes newly identified in quinoa

Charge cluster occurrence in land plants’ mitochondrial proteomes with functional and structural insights

The Charge Clusters (CCs) are involved in key functions and are distributed according to the organism, the protein’s type, and the charge of amino acids. In the present study, we have explored the occurrence, position, and annotation as a first large-scale study of the CCs in land plants mitochondrial proteomes. A new python script was used for data curation. The Finding Clusters Charge in Protein Sequences Program was performed after adjusting the reading window size. A 44316 protein sequences belonging to 52 species of land plants were analysed. The occurrence of Negative Charge Clusters (NCCs) (1.2%) is two times more frequent than the Positive Charge Clusters (PCCs) (0.64%). Moreover, 39 and 30 NCCs were conserved in 88 and 41 proteins in intra and in inter proteomes respectively, while 14 and 21 PCCs were conserved in 53 and 85 protein sequences in intra and inter proteomes consecutively. Sequences carrying mixed CCs are rare (0.12%). Despite this low abundance, CCs play a crucial role in protein function. The CCs tend to be located mainly in the terminal regions of proteins which guarantees specific protein targeting and import into the mitochondria. In addition, the functional annotation of CCs according to Gene Ontology shows that CCs are involved in binding functions of either proteins or macromolecules which are deployed in different metabolic and cellular processes such as RNA editing and transcription. This study may provide valuable information while considering the CCs in understanding the environmental adaptation of plants. Communicated by Ramaswamy H. Sarma</p
