Two Years Later: Journals Are Not Yet Enforcing the ARRIVE Guidelines on Reporting Standards for Pre-Clinical Animal Studies
David Baker,Katie Lidster ,Ana Sottomayor,Sandra Amor
PLOS Biology , 2014, DOI: 10.1371/journal.pbio.1001756
Abstract: There is growing concern that poor experimental design and lack of transparent reporting contribute to the frequent failure of pre-clinical animal studies to translate into treatments for human disease. In 2010, the Animal Research: Reporting of In Vivo Experiments (ARRIVE) guidelines were introduced to help improve reporting standards. They were published in PLOS Biology and endorsed by funding agencies and publishers and their journals, including PLOS, Nature research journals, and other top-tier journals. Yet our analysis of papers published in PLOS and Nature journals indicates that there has been very little improvement in reporting standards since then. This suggests that authors, referees, and editors generally are ignoring guidelines, and the editorial endorsement is yet to be effectively implemented.
Crystal structure, thermal analysis and IR spectroscopic investigation of bis (N-methyl anilinium) sulfate  [PDF]
Taha Guerfel, Amor Jouini
Open Journal of Inorganic Chemistry (OJIC) , 2011, DOI: 10.4236/ojic.2011.13007
Abstract: Chemical preparation, X-ray single crystal, thermal analysis and IR spectroscopic investigation of (C7H10N)2 SO4 denoted NMAS are described. The NMAS crystallizes in the triclinic system with P-1 space group. Its unit cell dimensions are a = 9.6150(5) Å, b = 9.9744(3) Å, c = 10.2767(6) Å, α = 68.069(3)°, β = 62.929(2)°, γ = 67.285(3)° with V = 785.72(7) Å3 and Z = 2. The structure has been solved using direct method and refined to a reliability R factor of 3.62%. The NMAS structure is built up from chains containing all the components of the structure and parallel to the b axis, linked via N—H­­­­­···O hydrogen bonds. Stability between successive chains is performed by weak interactions originating from the organic cations.
The Learning by Discovery Guided: Implementation in a Framework for the Training of Future Trainers in Civil Engineering  [PDF]
Hajer Ben Amor, Alia Maaloul
Creative Education (CE) , 2016, DOI: 10.4236/ce.2016.73046
Abstract: The main objective of a training program for future trainers Guineans, specialized and competent in Civil Engineering in training centers in their countries, is to use a new method of teaching by guided discovery in the framework of the course of Civil Engineering structures. In this context, a learning study was considered and put in application for the Higher Institute of Technological studies of Rades since November 2015 for a number of hours equal to 90. This innovative project brings together several aspects in Civil Engineering which are addressed through an analysis of a real case. The adopted approach is to apprehend a visit upstream of the teacher of the course in order to master the components of the job site to visit. Consequently, a guided tour of the students is programmed and provided by their teacher. The obtained results are satisfactory on the side of the learners in the field of learning, pedagogical innovation, motivation and profitability. However, these results remain still perfectible.
La supremacía de la mujer en la difusión romancística de la Leyenda de los Infantes de Lara
Amor,Lidia;
Temas medievales , 2008,
Abstract: this article analyses the legend of the infantes de lara where the female characters play a preeminent role which is especially apparent in the spanish romances. in fact, the romances dealing on this subject evince in their formal construction a specific interpretation according to which lambra and sancha occupy central positions in the family crisis and in the preservation of the family lineage.
La tierra y su relación con el botín en el Cantar de Mio Cid
Amor,Lidia;
Olivar , 2007,
Abstract: this article analyzes the importance of land as part of the booty obtained by the campeador during his campaigns in moorish territories. furthermore, land, and nourishment as its counterpart, not only differentiate rodrigo's initial situation from its final success as "se?or de frontera," but they also represent thematic components within the booty, in order to understand the opposition between estate ("heredad") and the place where the army can rest
Pour une syntaxe des titres des Faits Divers. Réflexion sur un corpus de titres de presse algérienne d’expression fran aise
Amor Tahar
Synergies Algerie , 2012,
Abstract: L’étude de l’intitulation que nous esquissons ici vise à explorer un modèle général des titres de presse, en s’appuyant sur la description d’un corpus de titres extrait d’un journal national. Partant de l’idée que la forme des titres des faits divers est régie par un ensemble restreint de règles de formation, nous essayons de déterminer l’ontologie de cette grammaire, pour pouvoir cerner, dans un second temps, quelques aspects de la fonction de la phrase-titre en lien avec la structuration du discours journalistique.
Suffosion et érosion hydrique en milieux semi-arides, le cas des Hautes Steppes tunisiennes (Tunisie centrale)
Amor Bkhairi
Physio-Géo , 2012, DOI: 10.4000/physio-geo.2246
Abstract: L'érosion hydrique est très active dans la région des Hautes Steppes tunisiennes, particulièrement dans les plaines alluviales où elle est très largement commandée par la suffosion. Cette dynamique érosive représente une menace sérieuse pour les terres agricoles. Les phénomènes érosifs liés à la suffosion provoquent des ravinements, des sapements de berge et l'élargissement de la section des oueds. Une cartographie morphodynamique détaillée, appuyée sur une prospection fine du terrain, l'exploitation de données spatiales multi-dates et l'étude de quelques cas, montre du reste la forte sensibilité de la région à l'érosion hydrique liée à la suffosion. Les formes de ravinement et le rythme des incisions linéaires mis en lumière par une étude diachronique de photographies aériennes orthorectifiées, pose le problème des facteurs de cette évolution accélérée : agressivité des pluies, érodibilité des sols et des formations à l'affleurement, inclinaison des pentes, modestie du couvert végétal et action anthropique inadaptée. Hydric erosion is very active in the Upper Steppes area of Tunisia chiefly on the alluvial floodplains where it is largely controlled by suffusion. This erosive dynamic represents a threat for the agricultural lands. The erosive phenomena related to suffusion, causes gullying, banks undermining and enlargement of the section of wadis. A morphodynamic mapping based on field-observations, the exploitation of aerial photos multi-date data, and the study of some examples put moreover in evidence the sensibility of the area to erosion phenomena in relation with suffusion. The forms of gullying and a comparative study of orthorectified air photographs pose the problem of the factors of this accelerated evolution: rainfall aggressivity, soil erodibility, inclination of the slopes, weakness of the vegetal cover and inappropriate human activities.
Reconstruction of Brooksville Ridge Cave Temperatures from Speleothem Samples
Amor Elder
Undergraduate Journal of Mathematical Modeling : One + Two , 2009, DOI: 10.5038/2326-3652.2.1.1
Abstract: A problem was proposed to use an adjusted version of Dorale's speleothem delta function to model the temperature fluctuations in the Brooksville Ridge Cave from the Medieval Warm Period to the present. The temperature values reconstructed by the model can be compared to the known temperature trend during the same selected time period. If the results matched the trend, it indicates that the cave's temperature was the dominant influence. If not, a different variable was the main influence of the cave. Using δ18O values gathered from a speleothem, past temperatures of the cave were modeled. Results show that the model's temperature trend did not match the known temperature trend, indicating the main variable affecting the δ18O values is more likely rainfall than temperature. This conclusion corresponds with the cave's location in Florida. Reconstructions of past climates can be used in modeling future climate changes as well as helping to support or disprove current evidence of hazardous climate changes.
Les charniers en Bosnie-Herzégovine. Les crimes contre les survivants
Amor Masovic
Astérion , 2005,
Abstract: Amor Masovic, responsable de la commission de recherche des disparus en Bosnie-Herzégovine et ancien responsable de la commission pour l’échange des prisonniers pendant la guerre de 1992-1995, nous présente ensuite un tableau accablant des disparitions dans les guerres récentes en ex-Yougoslavie, et des pratiques pour faire en sorte que ceux-ci ne soient ni retrouvés ni, encore moins, identifiés (d’où des fosses communes de deux types : primaires – où les corps furent enterrés initialement – et secondaires – où ces mêmes corps furent ré-enterrés, souvent démembrés, après avoir été déterrés pour être dispersés et moins aisés à repérer). 28 000 des 40 000 disparus ex-Yougoslaves relèvent du conflit en Bosnie et sont à 95 % des civils protégés par les conventions de Genève. Sur les 280 charniers identifiés la plupart se trouvaient à l’arrière et non sur le front et les disparitions sont datables à des périodes de non-combat. Le but de la commission est donc d’abord de retrouver et identifier les morts pour faire savoir et permettre le deuil (puisque la barbarisation qui a été exercée est double : contre les victimes et contre leurs familles qui ne peuvent vivre tant qu’elles n’ont pas de certitude). En outre, faute de disposition légale et d’une absence de droit spécifique des disparus personne ne peut être incriminé pour une disparition devant le TPIY où les disparus ne sont donc pas représentés. Amor Masovic tire quatre conclusions de son exposé : 1) la barbarie exprimée aujourd’hui est pour partie un résultat des manques de la justice à l’égard des crimes de guerre de la seconde guerre mondiale ; 2) la guerre contre les civils augmente en même temps qu’augmentent les dispositions internationales contre ces exactions qui restent donc purement formelles ; 3) en Bosnie, la barbarisation s’est exercée sur les corps des victimes de fa on redoublée puisque l’anéantissement des preuves du crime fait que la mort n’est pas une vraie fin. D’où une forme particulière de barbarisation d’après-guerre ; 4) seul élément plus positif : en Bosnie des échanges de prisonniers eurent lieu pendant la guerre sans attendre la fin du conflit ce qui est rarissime et va au-delà des exigences posées par les conventions de Genève en matière de libération des prisonniers.
VoIP Technology: Security Issues Analysis
Amor Lazzez
Computer Science , 2013,
Abstract: Voice over IP (VoIP) is the technology allowing voice and multimedia transmissions as data packets over a private or a public IP network. Thanks to the benefits that it may provide, the VoIP technology is increasingly attracting attention and interest in the industry. Actually, VoIP allows significant benefits for customers and communication services providers such as cost savings, rich media service, phone and service portability, mobility, and the integration with other applications. Nevertheless, the deployment of the VoIP technology encounters many challenges such as architecture complexity, interoperability issues, QoS issues, and security concerns. Among these disadvantages, VoIP security issues are becoming more serious because traditional security devices, protocols, and architectures cannot adequately protect VoIP systems from recent intelligent attacks. The aim of this paper is carry out a deep analysis of the security concerns of the VoIP technology. Firstly, we present a brief overview about the VoIP technology. Then, we discuss security attacks and vulnerabilities related to VoIP protocols and devices. After that, we talk about the security profiles of the VoIP protocols, and we present the main security components designed to help the deployment of a reliable and secured VoIP systems.
