MOMBERT (Monique). â Jeunesse et livre en Zone française dâoccupation 1945-1949. Sous le signe de la rĂ©Ă©ducation
En plaçant son ouvrage « sous le signe de la rĂ©Ă©ducation », lâauteur montre bien que la politique de jeunesse et du livre pratiquĂ©e de 1945 Ă 1949 en Zone française dâoccupation (ZFO) en Allemagne visait en premier lieu Ă rĂ©Ă©duquer la jeunesse allemande, cette politique de rĂ©Ă©ducation nâĂ©tant elle-mĂȘme quâun aspect dâune politique plus vaste de dĂ©nazification, de dĂ©militarisation et finalement de dĂ©mocratisation, conformĂ©ment Ă trois des quatre grands « D » dĂ©finis Ă Potsdam par les vainqueur..
A complete SPICE subcircuit-based model library for organic photodiodes
A precise model library based on an equivalent circuit is presented and
discussed. The model fully describes the light and bias behaviours of organic
photodiodes realized on plastic substrates. The sub circuit modelling consists
of a single SPICE LEVEL1 diode, a light power dependent series resistance, a
shunt resistance. A combined light-power and voltage-controlled current source
is also used to emulate the sensitivity behaviour of the photodiode. Moreover
the model also permits designers to follow the technology deviations through
the inclusion of worst-case corners. Finally a statistical model is included in
order to allow designers run Monte Carlo simulations
Approche expérimentale de l'amorçage de la CSC des aciers inoxydables austénitiques pré-déformés en milieu primaire de REP
National audienceLes aciers inoxydables de type 304L et 316L sont trÚs employés dans le circuit primaire des centrales nucléaires REP du fait de leur bonne résistance à la corrosion généralisée à haute température. Quelques cas de corrosion sous contrainte (CSC) de type intergranulaire ont toutefois été rapportés en milieu primaire nominal. La présente étude vise à développer un modÚle semi-empirique de l'amorçage de la CSC intergranulaire des aciers inoxydables 304L et 316L pré-déformés par traction et à améliorer la compréhension du rÎle de la pré-déformation sur les mécanismes de la CSC. Des résultats obtenus en parallÚle par le CEA sur un autre acier 316L, de composition chimique différente, et pour une autre voie de pré-déformation (laminage) seront également discutés
Detection of Extensive Cross-Neutralization between Pandemic and Seasonal A/H1N1 Influenza Viruses Using a Pseudotype Neutralization Assay
BACKGROUND: Cross-immunity between seasonal and pandemic A/H1N1 influenza viruses remains uncertain. In particular, the extent that previous infection or vaccination by seasonal A/H1N1 viruses can elicit protective immunity against pandemic A/H1N1 is unclear. METHODOLOGY/PRINCIPAL FINDINGS: Neutralizing titers against seasonal A/H1N1 (A/Brisbane/59/2007) and against pandemic A/H1N1 (A/California/04/2009) were measured using an HIV-1-based pseudovirus neutralization assay. Using this highly sensitive assay, we found that a large fraction of subjects who had never been exposed to pandemic A/H1N1 express high levels of pandemic A/H1N1 neutralizing titers. A significant correlation was seen between neutralization of pandemic A/H1N1 and neutralization of a standard seasonal A/H1N1 strain. Significantly higher pandemic A/H1N1 neutralizing titers were measured in subjects who had received vaccination against seasonal influenza in 2008-2009. Higher pandemic neutralizing titers were also measured in subjects over 60 years of age. CONCLUSIONS/SIGNIFICANCE: Our findings reveal that the extent of protective cross-immunity between seasonal and pandemic A/H1N1 influenza viruses may be more important than previously estimated. This cross-immunity could provide a possible explanation of the relatively mild profile of the recent influenza pandemic
The ANTENATAL multicentre study to predict postnatal renal outcome in fetuses with posterior urethral valves: objectives and design
Abstract
Background
Posterior urethral valves (PUV) account for 17% of paediatric end-stage renal disease. A major issue in the management of PUV is prenatal prediction of postnatal renal function. Fetal ultrasound and fetal urine biochemistry are currently employed for this prediction, but clearly lack precision. We previously developed a fetal urine peptide signature that predicted in utero with high precision postnatal renal function in fetuses with PUV. We describe here the objectives and design of the prospective international multicentre ANTENATAL (multicentre validation of a fetal urine peptidome-based classifier to predict postnatal renal function in posterior urethral valves) study, set up to validate this fetal urine peptide signature.
Methods
Participants will be PUV pregnancies enrolled from 2017 to 2021 and followed up until 2023 in >30 European centres endorsed and supported by European reference networks for rare urological disorders (ERN eUROGEN) and rare kidney diseases (ERN ERKNet). The endpoint will be renal/patient survival at 2 years postnatally. Assuming αâ=â0.05, 1âÎČâ=â0.8 and a mean prevalence of severe renal outcome in PUV individuals of 0.35, 400 patients need to be enrolled to validate the previously reported sensitivity and specificity of the peptide signature.
Results
In this largest multicentre study of antenatally detected PUV, we anticipate bringing a novel tool to the clinic. Based on urinary peptides and potentially amended in the future with additional omics traits, this tool will be able to precisely quantify postnatal renal survival in PUV pregnancies. The main limitation of the employed approach is the need for specialized equipment.
Conclusions
Accurate risk assessment in the prenatal period should strongly improve the management of fetuses with PUV
Age at onset as stratifier in idiopathic Parkinsonâs disease â effect of ageing and polygenic risk score on clinical phenotypes
Several phenotypic differences observed in Parkinsonâs disease (PD) patients have been linked to age at onset (AAO). We endeavoured to find out whether these differences are due to the ageing process itself by using a combined dataset of idiopathic PD (nâ=â430) and healthy controls (HC; nâ=â556) excluding carriers of known PD-linked genetic mutations in both groups. We found several significant effects of AAO on motor and non-motor symptoms in PD, but when comparing the effects of age on these symptoms with HC (using age at assessment, AAA), only positive associations of AAA with burden of motor symptoms and cognitive impairment were significantly different between PD vs HC. Furthermore, we explored a potential effect of polygenic risk score (PRS) on clinical phenotype and identified a significant inverse correlation of AAO and PRS in PD. No significant association between PRS and severity of clinical symptoms was found. We conclude that the observed non-motor phenotypic differences in PD based on AAO are largely driven by the ageing process itself and not by a specific profile of neurodegeneration linked to AAO in the idiopathic PD patients
Lâeffondrement de la RDA (mai 1989 â mars 1990)
En mai/juin 1989, deux Ă©vĂ©nements font apparaĂźtre Ă quel point la situation intĂ©rieure et extĂ©rieure de la RDA a Ă©voluĂ© dans le courant des annĂ©es 1980 : les Ă©lections communales, Ă©vĂ©nement en soi sans importance majeure, dĂ©notent une Ă©volution des mentalitĂ©s tandis que le dĂ©but du dĂ©mantĂšlement du rideau de fer Ă la frontiĂšre austro-hongroise montre que, depuis lâarrivĂ©e au pouvoir de MikhaĂŻl Gorbatchev, lâenvironnement international de la RDA sâest, lui aussi, profondĂ©ment modifiĂ©.

Un fédéralisme réformé
En juillet 2005, le prĂ©sident fĂ©dĂ©ral en personne, Horst Köhler, dĂ©clarait que « lâordre fĂ©dĂ©ratif allemand Ă©tait dĂ©passé ». Cette prise de position avait surpris ; elle synthĂ©tisait pourtant, dans une formule sans doute quelque peu abrupte, une sĂ©rie de critiques qui sâĂ©taient amplifiĂ©es avec le temps Ă lâencontre du fĂ©dĂ©ralisme allemand. Ce qui, des dĂ©cennies durant, avait passĂ© pour ĂȘtre un atout majeur permettant de concilier « unitĂ© et diversité » se serait dĂ©sormais retournĂ© contre lui...
