Ce troisième rapport de l'Observatoire national de la démographie des professions de santé comporte une synthèse générale assortie de préconisations et de quatre tomes thématiques : la médecine générale (tome 1), les internes en médecine (tome 2), la profession de chirurgien dentiste et les métiers de la périnatalité (tome 3), les métiers de la cancérologie (tome 4).
Antibacterial Activity of Desert Truffles from Saudi Arabia Against Staphylococcus aureus and Pseudomonas aeruginosa
2017
Abstract Medicinal mushrooms represent an unlimited source of polysaccharides with nutritional, antitumoral, antibacterial, and immune-stimulating properties. Traditional studies of epigeous higher Basidiomycetes have recently been joined by studies of hypogeous fungi and, in particular, of so-called desert truffles. With the aim to obtain novel agents against bacteria of clinical importance, we focused on the edible desert truffle mushrooms Tirmania pinoyi, Terfezia claveryi, and Picoa juniperi as sources of new antimicrobial agents. In particular, we investigated the in vitro antibacterial activity of acid-soluble protein extracts (aqueous extracts) of these 3 species against the Gram-pos…
Inversion of matrix pencils for generalized systems
1993
Abstract This paper clarifies the nature of the Leverrier-Faddeev algorithm for generalized and state-space systems. It presents useful diagrams for recursive computation of the coefficients of the characteristic polynomial and the coefficient matrices of the adjoint matrix for various matrix pencils. A simplified case covers recursive equations and diagrams for inversion of the second-order matrix pencil (Es2 + A1s + A0) where E may be singular. The appendix provides two examples of mechanical and heat exchange systems which can be described by the generalized models.

A more efficient second order blind identification method for separation of uncorrelated stationary time series
2016
The classical second order source separation methods use approximate joint diagonalization of autocovariance matrices with several lags to estimate the unmixing matrix. Based on recent asymptotic results, we propose a novel unmixing matrix estimator which selects the best lag set from a finite set of candidate sets specified by the user. The theory is illustrated by a simulation study.
Higher order matrix differential equations with singular coefficient matrices
2015
In this article, the class of higher order linear matrix differential equations with constant coefficient matrices and stochastic process terms is studied. The coefficient of the highest order is considered to be singular; thus, rendering the response determination of such systems in a straightforward manner a difficult task. In this regard, the notion of the generalized inverse of a singular matrix is used for determining response statistics. Further, an application relevant to engineering dynamics problems is included.
Low-cost solutions for manipulation tasks in manufacturing systems: balancing costs and performances
2010
Abstract Industrial robots are distinguished from other types of machinery mainly on the basis of their programmability and adaptability to different tasks. However, the cost s of the state of the art solutions for every system within their structure became very high compared with some applications. This work presents two proposed solutions of so called robotic manipulators, which may fulfil some of the manipulating tasks specific to industrial robots while using low-cost solutions of transmission, actuation and automation systems.
LA TECNICA Y LA CRISIS FILOSOFICA DEL HUMANISMO
2008
Los acontecimientos civilizatorios que emblemáticamente representamos con nombres como Auschwitz o Hiroshima han hecho visible que la comprensión de la realidad como técnicamente abordable obliga a replantear problemas centrales para la filosofía: la omnipresencia de la técnica transforma el modo de vida de los individuos y las sociedades contemporáneas, el vínculo del hombre con la naturaleza y el vinculo social, no menos que los modos de construcción de la subjetividad humana. El presente escrito intenta oponer a la destrucción heideggeriana del sujeto la idea de que, en la presente crisis abierta por las posibilidades inéditas de las tecnologías, es imprescindible una reconstrucción del …
Painful procedures in the NICU
2012
The authors after a brief introduction on the development of the perception of pain in the fetus and newborn, focus attention on the problem of painful procedures that are performed in the neonatal intensive care units reported in the scientific literature. Then report the design of the double-blind study that is taking place from February 2012 at the NICU ARNAS Civic - Palermo using three different concentrations of sucrose as analgesia during venipuncture and heel puncture in term neonates.
Environment, information, fake news. Information Disorder. Learning to Recognize Fake News. Fake News
2022
Although more than 25 years have passed since the publication of a report that clearly shows the scientific evidence on global warming and the influence of human activity, today there are still thousands of fake news stories circulating on the web. Lobbies have always used the media to discredit science, and with the boom in social media this strategy has shifted online. Deniers single out items of scientific truth and use them instrumentally to render fake news credible. After years of a widespread lack of control, something is changing: since 2020, Facebook has created the "Climate Science Information Center", a platform that signals fake climate news and encourages people to consult offi…
