Bone requires a mechanical stimulus for growth; hence, in a bone-implant coupling, it is essential to use materials with stiffness properties similar to bone for improving the load-transfer and favoring bone healing and remodeling. One alternative method of lowering the elastic is developing porous materials (metallic foams) that have demonstrated their potential to allow rapid bone ingrowth. Another important aspect of the use of biomaterials is linked with medical device-related infections. These infections may cause an implant failure, with the corresponding implant revision or removal process and the associatedpatient’s pain and costs. Recently, it has been shown that functional metal ions such as Ca, Sr, Mg and Ag can be incorporated into the Ti surface by modifying the conditions or the thermochemical treatment [35]. In this regard, ...

Pour répondre à cette problématique, nous devons répondre a deux questions ; Quels sont les biens culturels qu’on va cibler dans notre étude ? Quels sont les risques de dégradation de ses biens ?

One benefit of using wireline log data to estimate permeability is that it can provide a continuous permeability profile throughout a particular interval. This study will focus on the evaluation of formation permeability for a sandstone reservoir in the reservoir formations of Hassi R'Mel Field Southern from well log data using the multivariate methods. In order to improve the permeability estimation in these reservoirs, several statistical regression techniques have already been tested in previous work to correlate permeability with different well logs. It has been shown that statistical regression for data correlation is quite promising. We propose a two-step approach to permeability prediction that utilizes non-parametric regression in conjunction with multivariate statistical analysis. First we classify the well log data into electrofacies types. A combination of principal component analysis, model-based cluster analysis and discriminant analysis is used to characterize and identify electrofacies types. Second, we apply nonparametric regression techniques to predict permeability using well logs within each electrofacies. Three non-parametric approaches are examined via alternating conditional expectations (ACE), generalized additive model (GAM) and neural networks (NNET) and the relative advantages and disadvantages are explored. The results are compared with three other approaches to permeability predictions that utilize data partitioning based on reservoir layering, lithofacies information and hydraulic flow units. An examination of the error rates associated with discriminant analysis for uncored wells indicates that data classification based on electrofacies characterization is more robust compared to other approaches.

A travers notre observation, nous soulignons l’interet et les donnees de la radiologie dans le diagnostic de ces atteintes qui restent rares. Materiels et methodes Nous rapportons le cas d’un patient de 41 ans, initialement admis en psychiatrie pour troubles du comportement avec heteroaggressivite et fugues. L’examen neurologique avait trouve un syndrome confusionnel, un syndrome cerebelleux et une irritation tetrapyramidale. Resultats La TDM cerebrale avait montre une forte prise de contraste de la base, avec un nodule temporal gauche rehausse par l’injection iodee. L’IRM avait montre une prise de contraste des meninges et de la toile choroidienne avec multiples nodules sus et sous-tentoriels, ainsi qu’au niveau du cone medullaire, rehausses par le Gadolinium. Nous avons retenu le diagnostic de sarcoidose sur l’association d’arguments radiologiques et biologiques. Conclusion La neurosarcoidose reste rare. La mise en evidence de signes radiologiques (neurologiques et extra-neurologiques) evocateurs est d’un grand secours au diagnostic qui est souvent pose sur un faisceau d’arguments. Le scanner et l’IRM ont egalement un grand interet dans la surveillance et le suivi sous traitement.

While computing the number of frequency of an item we need to scan the given database many times. So we used counting inference approach for finding frequent itemsets at each concept levels which reduce the number of scan. In this paper, we purpose a new algorithm LWFT which follow the top-down progressive deepening method and it is based on existing algorithms for finding multiple level association rules. This algorithm is efficient for finding frequent itemsets from large databases.

Summary Background Data: Previous reports have been centerspecific or from large databases lacking detailed variables. The Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL) represents the first detailed North American multicenter report of recipient risk and outcome aiming to characterize variables predictive of graft failure. Methods: Three hundred eighty-five ALDLT recipients transplanted at 9 centers were studied with analysis of over 35 donor, recipient, intraoperative, and postoperative variables. Cox regression models were used to examine the relationship of variables to the risk of graft failure. Results: Ninety-day and 1-year graft survival were 87% and 81%, respectively. Fifty-one (13.2%) grafts failed in the first 90 days. The most common causes of graft failure were vascular thrombosis, primary nonfunction, and sepsis. Biliary complications were common (30% early, 11% late). Older recipient age and length of cold ischemia were significant predictors of graft failure. Center experience greater than 20 ALDLT was associated with a significantly lower risk of graft failure. Recipient Model for End-stage Liver Disease score and graft size were not significant predictors. Conclusions: This multicenter A2ALL experience provides evidence that ALDLT is a viable option for liver replacement. Older recipient age and prolonged cold ischemia time increase the risk of graft failure. Outcomes improve with increasing center experience.

In the model of ischemia/isolated perfusion, treatment of genetically obese Zucker rats with the HO-1 inducer cobalt protoporphyrin (CoPP) or with adenoviral HO-1 (Ad-HO-1) significantly improved portal venous blood flow, increased bile production, and decreased hepatocyte injury. Unlike in untreated rats or those pretreated with the HO
