Resonance frequency analysis after the placement of 133 dental implants
2006
Introducción: La estabilidad primaria del implante dental está relacionada con el hueso que se encuentra en contacto con él y se puede medir mediante el análisis de frecuencia de resonancia. Material y métodos: En 133 implantes (62 en maxilar y 71 en mandíbula) se midió la frecuencia de resonancia y la fuerza de inserción para conocer la estabilidad de los implantes el día de la cirugía, y estudiar su relación con distintas variables. Resultados: El cociente de estabilidad del implante obtenido el día de la cirugía fue de 62’1 y el de la fuerza de inserción fue de 35’7 Nw. La fuerza de inserción fue proporcional al análisis de la frecuencia de resonancia, a mayor fuerza de inserción mayor c…
Effets de la nutrition et du génotype de la plante sur la résistance de Medicago truncatula à Aphanomyces euteiches
2016
SPEIPMUBAGROSUPINRA; Dans la nature, les plantes ont la capacité de mettre en oeuvre des réponses immunitaires pour faire face aux microorganismes pathogènes. Cependant, ces réponses de défense sont coûteuses en énergie et conduisent la plante à détourner une partie de ces ressources destinées à d’autres traits de vie comme la croissance. Ce compromis défense/croissance est largement conditionné par la disponibilité extérieure en nutriments. Afin de mieux décrire et comprendre les liens entre la nutrition et la défense, nous avons analysé l’impact de la nutrition azotée et l’effet de la variabilité génétique végétale sur la capacité de la légumineuse Medicago truncatula à résister à un agen…
Identification of Bioactive Compounds in Polar and Nonpolar Extracts of Araujia sericifera
2017
Abstract Araujia sericifera is a native perennial, climbing laticiferous shrub from South America that is currently naturalized in many other countries. Previous data describe promising properties for A. sericifera, but no systematic study of its bioactive compounds and possible medicinal applications has been conducted to date. In the present study, aerial parts of A. sericifera (leaves, stems, and fruits) were explored by combining GC-MS and NMR spectroscopy analysis for both nonpolar (hexane) and polar (methanol) extracts. The hexanic extracts contained high amounts of pentacyclic triterpenes including two new metabolites, 3-tigloyl germanicol (18) and 3-tigloyl lupeol (19). The methanol…
The onset of the rainy season and farmers’ sowing strategy for pearl millet cultivation in Southwest Niger
2011
A multi-year (2004-2009) field survey of on-farm sowing practices in 10 villages located in south-west Niger close to Niamey, is analysed to investigate the relationships (i) between rainfall and the sowing date of pearl millet and the risk of sowing failure, (ii) between sowing and meteorological/agro-climatic onset dates, (iii) between sowing/onset dates, and simulated and observed yield/biomass at the end of the season. Even if some villages sow without any synchronous or anterior rainfall, most parcels (73% out of the 1551 available cases) are sown during and just after a 2-day wet spell receiving at least 10 mm. In fact, there is a strong correlation (r = 0.82-0.95 depending on onset d…
Behavior of polyether-ether-ketone (PEEK) in prostheses on dental implants. A review.
2020
Background The development of new and innovative materials such as high performance polymers (PEEK) opens a wide therapeutic range in implant prostheses. They are presented as alternative materials to metal and zirconium alloys in the manufacture of structures and attachments for implant prostheses and fixed and removable dental substitutes. The objective of this review is to know the characteristics of this material and thus assess its advantages and disadvantages in its possible applications in prostheses on dental implants. Material and methods A bibliographic search was carried out through the PubMed and Scopus search engines, of articles published from 2007 to 2020, excluding all artic…

Phosphorus recovery by struvite crystallization in WWTPs: Influence of the sludge treatment line operation
2010
Phosphorus recovery by struvite (MgNH(4)PO(4).6H(2)O) crystallization is one of the most widely recommended technologies for treating sludge digester liquors especially in wastewater treatments plants (WWTP) with enhanced biological phosphorus removal (EBPR). In this paper, phosphorus recovery by struvite crystallization is assessed using the rejected liquors resulting from four different operational strategies of the sludge treatment line. Phosphorus precipitation and recovery efficiencies of between 80-90% and 70-85%, respectively, were achieved in the four experiments. The precipitates formed were mainly struvite, followed by amorphous calcium phosphate and, in some experiments, by calci…
