Small-diameter titanium Grade IV and titanium-zirconium implants in edentulous mandibles: three-year results from a double-blind, randomized controll…
2015
OBJECTIVE: The aim of this study was to compare crestal bone-level changes, soft tissue parameters and implant success and survival between small-diameter implants made of titanium/zirconium (TiZr) alloy or of Grade IV titanium (Ti) in edentulous mandibles restored with removable overdentures. MATERIALS AND METHODS: This was a randomized, controlled, double-blind, split-mouth multicenter clinical trial. Patients with edentulous mandibles received two Straumann bone-level implants (diameter 3.3 mm), one of Ti Grade IV (control) and one of TiZr (test), in the interforaminal region. Implants were loaded after 6-8 weeks and removable Locator-retained overdentures were placed within 2 weeks of l…
Nomenclature et régulation médicalisée en médecine ambulatoire
1993
La récente négociation d'une nouvelle convention médicale pour la médecine libérale ne s'est pas effectuée sans difficulté. Le compromis qui a permis la signature de cette convention a retenu le principe d'une responsabilisation des médecins à travers un projet de maîtrise médicalisée. Ce projet conduit à réformer la nomenclature des actes en vigueur depuis 1972 et à définir de nouveaux référentiels de l'activité médicale qui serviraient de base à l'évaluation et à la maîtrise de cette activité. Toutefois; les objectifs d'un nouveau codage des actes ne sont pas clairement définis et l'efficacité d'une telle politique pour réduire les dépenses est loin d'être garantie.En effet, la réforme de…
Comparative in vitro study of the accuracy of impression techniques for dental implants: Direct technique with an elastomeric impression material ver…
2019
Background The aim of this study was to compare a conventional technique (elastomeric impression material - EIM) and a digital technique (scanner digital model – SDM) on a six-analog master model (MM) to determine which was the most exact. Material and Methods Twenty impressions were taken of a master model (EIM) and twenty scanned impressions (SDM) (True Definition). A coordinate measuring machine (CMM) was used to measure the distances between adjacent analogues (1-2, 2-3, 3-4, 4-5, 5-6), intermittently positioned analogues (1-4, 3-6) and the most distal (1-6). Reference values were established from the master model, which were compared with the two impression techniques. The significance…
Eiropas Savienības ārējās robežas Latvijā tiesiskā reglamentācija
2014
ANOTĀCIJA Pētījums veltīts Eiropas Savienības ārējo robežu Latvijā normatīvā regulējuma problemātikai starptautisko, Eiropas Savienības un nacionālo tiesību jomā Latvijas kā starptautisko tiesību subjekta suverenitātes, teritoriālās jurisdikcijas un valsts robežas kontekstā saistībā ar personu brīvas pārvietošanās īstenošanu Šengenas acquis (Šengenas tiesību kopuma) darbības telpā. Valsts robeža ir jebkuras valsts suverenitātes un drošības komponente. Tās pamatu veido valsts robežas režīma normatīvais regulējums, kas Eiropas Savienības tiesībās ir jāattīsta kopsakarā ar starptautiskajām tiesībām un Latvijas, tāpat kā citu Šengenas konvencijas dalībvalstu, starptautiskajām tiesiskajām saistī…
Estudio de la eficacia escolar en centros educativos de primaria mediante el uso de Modelos Jerárquicos Lineales
2021
espanolINTRODUCCION. Se presenta un estudio censal sobre la eficacia escolar en los centros educativos de primaria de la comunidad autonoma de La Rioja, un analisis secundario de una evaluacion diagnostica (ED) previa en esa comunidad. Se valoro el impacto de variables contextuales en los rendimientos de las asignaturas evaluadas no usando las puntuaciones medias brutas obtenidas en la ED, sino las puntuaciones medias ajustadas una vez controlado el efecto de variables contextuales. METODO. El control se realizo por modelizacion estadistica multinivel con modelos jerarquicos lineales en dos niveles: estudiantes y centros. Los residuos de los modelos se usaron como criterio de eficacia escol…
The Effect of Nonlinear Response of the Primary System in Nonconventional TMDs
2023
Tuned Mass Dampers (TMD) have been widely used in the passive vibration control of engineering structures, both under wind and seismic loads. Under wind loads, a proper frequency tuning ensures a significant response reduction of the primary structure. While under wind loads the structure is likely to remain in the elastic range of behaviour, when large earthquakes occur it can experience inelastic deformations and damage, with a consequent de-tuning effect. In this paper, nonconventional TMDs with large mass ratios, realized through Interstory Isolation Systems (IIS), are considered and the influence of the inelastic behaviour of the primary system on the overall structure response is anal…
Effectiveness of isolated vertical extension of masonry buildings as nonconventional TMD
2023
In this paper, the strategy of Intermediate Isolation System (IIS) is proposed for the vertical extension of an aggregate of masonry buildings located in Pozzuoli, south Italy. The effectiveness of IIS working as a nonconventional Tuned Mass Damper (TMD) for the existing construction is assessed in terms of reduction of seismic demand and damage in the masonry structure undergoing inelastic deformation under seismic input. For this aim, a general step-by-step procedure is first defined and then applied to the case study building. In particular, the characterization of dynamic behaviour and seismic capacity of the building aggregate is first addressed through modal and push over analyses. El…
Good, safe and fair: Quality perception and consumer demand of Locally produced beef in Southern Italy
2017
The increasing concern amongst consumers regarding the safety and quality of the beef that they buy is the result of food scares that have characterized the beef market in the last two decades. These scares, together with environmental and ethical concerns, caused consumers to reflect upon the quality of the beef they eat. The aim of this paper is to identify which quality characteristics influence the incidence of local beef consumption on the total consumption of beef. It is assumed in this study that such choice is a response to a process of quality evaluation, which occurs combining specific quality attributes and socially constructed food quality criteria strictly linked to a socially …
CITES and Cacti a user's guide
2012
This user’s guide covers the widely traded cactus family and how it is regulated by the Convention on International Trade in Endangered Species (CITES). The guide explores the major groups of cacti in trade, their distribution, conservation status, use and levels of trade as well as the likelihood of illegal trade. All CITES Appendix I taxa and a wide selection of Appendix II taxa are covered in detail. Major exemptions from CITES regulations are also outlined, including cacti not covered by CITES. The guide includes a fully illustrated PowerPoint training presentation with comprehensive speaker notes on CD-ROM.

The conservation of biodiversity is a worldwide recognised priority, now fully included in the inter-national agenda of the United Nations. Several international conventions call states to work towards the halt of the depletion of biodiversity and the promotion of a better environment. The Convention on International Trade in Endangered Species (CITES) and the Convention on Biological Diversity (CBD) are widely recognised as today’s leading environmental conventions. CITES monitors and regulates the international trade of plants and animals and it is in force since 1975. During 36 years of action it saved from extinction several species and it is enforced in almost all states. The CBD goes …
