Long-term volume-targeted pressure-controlled ventilation: sense or nonsense?
2017
The technology underlying the development of novel ventilatory modes for long-term noninvasive ventilation of patients with chronic hypercapnia is continuously evolving. Volume-targeted pressure-controlled ventilation is a hybrid ventilation mode designed to combine the advantages of conventional ventilation modes, while avoiding their drawbacks. However, manufacturers have created different names and have patented algorithms and set-up variables, which can result in confusion for physicians and respiratory therapists. In addition, clear evidence for the superiority of this novel mode has not yet been established. These factors have most likely hindered more widespread use of this mode in c…
Laser Welding - Suitable for Vascular Anastomosis?
1994
Carotid arteries of 21 piglets were transsected and reanastomosed either by laser welding (Neodym:YAG laser) or by conventional suture anastomosis. Histological specimens of the anastomoses obtained 2 to 32 days after the operation showed less foreign body reaction and intimal hyperplasia after laser welding than after suturing. There was, however, no significant difference when comparing occurrence of thrombosis, patency rate, or growth of the anastomosis in growing animals. Neither our study nor a review of the literature of laser-assisted vascular anastomosis in microvessels and large arteries up to 5 mm diameter could establish a definite clinical application for laser welding in vascul…

On the blockwise modular isomorphism problem
2017
As a generalization of the modular isomorphism problem we study the behavior of defect groups under Morita equivalence of blocks of finite groups over algebraically closed fields of positive characteristic. We prove that the Morita equivalence class of a block B of defect at most 3 determines the defect groups of B up to isomorphism. In characteristic 0 we prove similar results for metacyclic defect groups and 2-blocks of defect 4. In the second part of the paper we investigate the situation for p-solvable groups G. Among other results we show that the group algebra of G itself determines if G has abelian Sylow p-subgroups.
Synthesis and preliminary biological evaluation of a new pyridocarbazole derivative covalently linked to a thymidine nucleoside as a potential target…
2003
The therapy of human cancer is one of the more pursued goals by medicinal chemistry research. Most of the compounds clinically used as a treatment owe their efficacy to their cytotoxic interaction (direct or indirect) with nuclear DNA. This interaction results in the inhibition of DNA synthesis and the degradation of nucleic strands. Ellipticine is a naturally occurring 6H-pyrido[4,3-b]carbazole alkaloid endowed with antitumor activity, and several ellipticine derivatives have been used in clinical trials. We previously reported some 1,4-dimethyl-9H-carbazole derivatives structurally related to ellipticine. The purpose of our research was to transform the pyridocarbazole in a prodrug so tha…
Peut-on parler de recherche en pédagogie universitaire, aujourd'hui, en France ?
2008
08102; Définir la pédagogie universitaire et savoir ce qu'elle recouvre en France en termes de recherche constitue un enjeu. En effet, le manque de visibilité et de lisibilité de ce champ en limitent probablement la portée à l'heure où la notion de qualité semble se faire plus pressante dans le contexte universitaire français. En partant d'une définition opérationnelle de ce que l'on peut entendre par pédagogie universitaire en France et en s'appuyant sur une recherche documentaire effectuée à partir de la base de données Francis ainsi que de la consultation de programmes complets de différents colloques, cet article vise à mettre en perspective et à illustrer les principaux axes de recherc…
Le caractère formatif d'un dispositif d'évaluation des enseignements par les étudiants (EEE)
2014
International audience; Cet article examine un dispositif d'évaluation des enseignements par les étudiants (EEE) en analysant les choix des équipes pédagogiques concernant les questionnaires qu'elles conçoivent. Cette étude est menée afin d'étudier la place possible de l'EEE dans le cadre de l'évaluation-conseil. En effet, pour que l'EEE soit utile aux enseignants, il convient que les questions posées aux étudiants permettent aux enseignants comme aux professionnels de l'accompagnement de s'inscrire dans une logique d'évaluation-conseil. Les résultats montrent leur intérêt dans ce cadre en fournissant aux enseignants des données qui leur permettent de conforter ou de modifier leurs enseigne…

A methodology for the sustainability assessment of agri-food systems: an application to the Slow Food Presidia project
2014
New and alternative models for agri-food production and consumption have brought up questions regarding the effects they have on local development processes in terms of the economic exploitation of rural areas as well as environmental, cultural, and social factors. The agri-food system proposed by the Slow Food (SF) Presidia Project, which focuses on farm-to-market systems for local, high-quality, sustainable products, can respond to the new and emerging needs of both rural and urban populaces via several approaches in addition to food production itself. However, evaluating these parameters is challenging. The aim of this study was to develop an indicator-based tool to monitor the sustainab…
La medida de la calidad educativa : acerca de los rankings universitarios
2017
En el presente texto se revisa desde una perspectiva critica la construccion de sistemas transnacionales de evaluacion de la calidad a traves de los rankings internacionales. En la primera parte, reflexionamos sobre el concepto de calidad y presentamos diferentes tipos de rankings: los denominados League Tables (ARWU, THE, QS) y los centrados en resultados de investigacion (SCImago Institutions Ranking). Una vez conocidas las caracteristicas y posibles utilidades de los mismos, analizamos dialogicamente una serie de riesgos a tener en cuenta para acabar incidiendo de nuevo en el modelo de calidad que proponen y sus posibles efectos.
