La presse d'extreme droite face au revisionnisme en France 1978-1990

Between 1978 and 1990 five newspapers close to Jean-Marie Le Pen's Front National had the choice of defining their stand on so-called révisionnisme which in its extreme form denied the existence of the Shoah, considering it to be the fabrication of a Jewish conspiracy. Within révisionnisme, a négationniste discourse affirmed that the gas chambers never existed, while a relativiste discourse denied that the Shoah was an act of genocide. However, most of the extreme-right newspapers did not adopt the cause of révisionnisme, even if they sometimes evinced an indulgence towards it. Only the weekly Rivarol and the militant François Brigneau who worked for Minute, Présent and National Hebdo and wrote the most on the subject openly espoused révisionnisme. The reasons for their stance included neo-fascist views, belief in a Jewish conspiracy. Their stance was in keeping with ideas commonly expressed in French neo-fascist circles that made for a révisionnisme of exculpation. On the other hand, the French Catholic intégriste milieu close to the Front National, which is represented by the newspapers Présent and Aspects de la France, was not generally révisionniste, notwithstanding the occasionnal expressions of relativisme by persons in the schismatic lefebvriste movement or close to Présent. This rejection of révisionnisme by Catholics on the extreme right was conditioned by various factors: the nature of Maurras's nationalisme intégral and anti-Semitism transmitted by I' Action française; the Catholic Church's modified position on the Jews; and the (offensive) atheism of the upholders of révisionnisme. This same révisionnisme extended beyond latter-day Nazi sympathisers. In its French version, it served to unite elements of the extreme right and the extreme left, as witness the role played by La Vieille Taupe, the extreme left group which was (and is) the leading publisher in France of tracts favouring révisionnisme.

High resolution demodulation platform for large capacity hybrid WDM/FDM microstructures sensing system assisted by tunable FP filter

In this paper we proposed a demodulation scheme based on tunable FP filter for the WDM/FDM sensing system of the microstructure mentioned in the previous work. Simulation is done to prove the feasibility of demodulating the microstructure with the tunable FP filter. The experiments result showed high consistence with the simulation. And with the help of the high speed FPGA module and a high resolution AD/DA card, the system has achieved a very high resolution, up to 2.5 pm, and wavelength ranges 1520nm to 1590 nm.

Influence of ferrule preparation with or without glass fiber post on fracture resistance of endodontically treated teeth

OBJECTIVE: This study evaluated the effect of ferrule preparation (Fp) on the fracture resistance of endodontically treated teeth, restored with composite resin cores with or without glass fiber posts. MATERIAL AND METHODS: Forty-four bovine teeth were sectioned 19 or 17 mm (2 mm ferrule) from the apex, endodontically treated and assigned to four groups (n = 11): Group 1: Fp and post; Group 2: Fp and without post; Group 3: without Fp and with post; Group 4: without Fp and without post. All specimens were restored with composite resin core and metal crown. Specimens were subjected to fracture resistance testing in a universal testing machine at a crosshead speed of 0.5 mm/min. The data were analyzed by two-way ANOVA and Tukey's tests (α=0.05). RESULTS: The mean fracture resistance values were as follows: Group 1: 573.3 N; Group 2: 552.5 N; Group 3: 275.3 N; Group 4: 258.6 N. Significantly higher fracture resistance was found for the groups with Fp (p<0.001). CONCLUSION: There was no statistically significant interaction between the "Fp" and "post" factors (p = 0.954). The ferrule preparation increased the fracture resistance of endodontically treated teeth. However, the use of glass fiber post showed no significant influence on the fracture resistance.

Ultraestrutura do nervo facial intratemporal em pacientes com paralisia facial idiopática: estudo de evidências de infecção viral

A etiologia da paralisia facial periférica idiopática (PFPI) ainda é uma incógnita, no entanto, alguns autores aventam a possibilidade de ser uma infecção viral. OBJETIVO: Analisar a ultraestrutura do nervo facial procurando evidências virais que possam nos fornecer dados etiológicos. MATERIAL E MÉTODO: Foram estudados 20 pacientes com PFP, com graus de moderado a severo, de ambos os sexos, entre 18-60 anos, provenientes de Ambulatório de Distúrbios do Nervo Facial. Os pacientes foram divididos em dois grupos: Estudo, onze pacientes com PFPI e Controle, nove pacientes com Paralisia Facial Periférica Traumática ou Tumoral. Foram estudados fragmentos de bainha do nervo facial ou fragmentos de seus cotos, que durante a cirurgia de reparação do nervo facial, seriam desprezados ou encaminhados para estudo anatomopatológico. O tecido foi fixado em glutaraldeído 2% e analisado em Microscopia Eletrônica de Transmissão. RESULTADO: Observamos no grupo estudo atividade celular intensa de reparação com aumento de fibras colágenas, fibroblastos com organelas desenvolvidas, isentos de partículas virais. No grupo controle esta atividade de reparação não foi evidente, mas também não foram observadas partículas virais. CONCLUSÃO: Não foram encontradas partículas virais, no entanto, houve evidências de intensa atividade de reparação ou infecção viral.

O rap, o hip-hop e o funk: a "eróptica" da arte juvenil invade a cena das escolas públicas nas metrópoles brasileiras

A irreverência e a criticidade de alguns rappers e o gingar alegre do corpo erótico proposto pelo funk sugerem um novo cenário para as metrópoles do país, em que a pluralidade da arte juvenil surge como forma de enfrentamento das marcas deixadas por fraturas sociais profundas. Os conceitos de "visão dionisíaca de mundo", "estética extrema" e "transvaloração dos valores", de Nietzsche, e o "erotismo", segundo Bataille, nortearam o método de ruptura de campo, concebido por Herrmann. Este, essencial para se repensar as noções de autoridade e tradição na sociedade contemporânea a partir das ideias veiculadas pelo rap e pelo funk. Consideramos que somente uma etnografia do olhar que apanhe a dimensão erótica e irreverente - a "eróptica", segundo Canevacci - destas manifestações poderia nelas identificar uma estética afirmativa e crítica, como diria Nietzsche, capaz de produzir uma verdadeira reversão dos valores em nossa sociedade e, no caso, no interior da própria escola.

Uso de hidrolizado proteico en los pacientes de una unida de terapia intensiva neonatal

Introducción. La leche humana es el primer alimento escogido para alimentar a los recién nacidos (RN), especialmente a los prematuros (RNPT y a los de peso muy bajo (RNMBP). Cuando esta leche no está disponible, deben ser recetadas fórmulas especializadas, que promuevan un crecimiento y desarrollo adecuados. El uso de los hidrolizados proteicos (HP) en la UTI neonatal ha sido promovido, debido al riesgo potencial que los RNPT/MBP presentan, por la inmadurez gastrointestinal, problemas de absorción e intolerancia alimentaria. Sin embargo, tales formulaciones no fueran elaboradas para atender las necessidades específicas de estos niños, y pueden, cuando son utilizadas, ocasionar un déficit nutricional. Objetivo. Comparar la progresión de la nutrición enteral (NE) (a través de la oferta de volumen, calorías y proteínas), la evolución ponderal, y las complicaciones clínicas entre recién nacidos de peso muy bajo (RNPMB) alimentados con fórmula para prematuros (FP) e hidrolizado proteico (HP) en la UTI neonatal. Casuística y métodos. Fueran estudiados dos grupos de RNPMB: grupo 1:13RNPMB con edad gestacional media de nacimiento de 30 semanas, peso medio de nacimiento de 1 167 gramos, que recibieron FP. Grupo 2:8 RN con edad gestacional media de nacimiento de 29 semanas, peso medio de nacimiento de 1 141 gramos, alimentados con HP. Las ofertas de volumen, la de calorías y la de proteínas fueran diariamente calculadas para todos los niños en ambos grupos. La nutrición parenteral (NP) que complementaría a la terapia nutricional en las primeras semanas, también fue calculada. Los RNMBP fueron pesados diariamente, por la mañana, en balanza digital (escala de 10 g) debidamente calibrada. El peso medio diario fue calculado hasta el dia 15 de vida. Fueron construidas curvas de crescimento, a través del polinomio de segundo grado para ambos grupos. Para el análisis estadístico se utilizó el test de medias. Resultados. ) La oferta media de volumen, calorías y proteínas fue mayos en la primera semana en el grupo 2, pero de una forma no significativa (p=0.38; 0.34 y 0.05, respectivamente). En las semanas subsequentes, no hubo diferencias significativas en la progresión de NE entre los grupos. No fueron observadas complicaciones clínicas, sólo ocurrieron dos casos de distensión abdominal en el grupo 1, pero no fueron caracterizados como enterocolitis necrosante (ECN). No hubo diferencias estadísticas relacionadas con el aumento de peso entre los dos grupos durante el periodo de estudio; sin embargo, el grupo 1 presentó una tendencia de mejor evolución. conclusión. La prograsión de la NE fue semejante con la utilización de los dos tipos de fórmulas, no feron encontradas diferencias en el aumento de peso de los grupos, y no hubo complicaciones clínicas en ninguno de ellos. No hubo ventajas en el uso del HP en la UTI neonatal; por tanto, no está indicado para RNPMB, sin disfunción intestinal, debido a que su composición nutricional no prevé las necesidades de este grupo de niños

Gravitational signature of Schwarzschild black holes in dynamical Chern-Simons gravity

Dynamical Chern-Simons gravity is an extension of general relativity in which the gravitational field is coupled to a scalar field through a parity-violating Chern-Simons term. In this framework, we study perturbations of spherically symmetric black hole spacetimes, assuming that the background scalar field vanishes. Our results suggest that these spacetimes are stable, and small perturbations die away as a ringdown. However, in contrast to standard general relativity, the gravitational waveforms are also driven by the scalar field. Thus, the gravitational oscillation modes of black holes carry imprints of the coupling to the scalar field. This is a smoking gun for Chern-Simons theory and could be tested with gravitational-wave detectors, such as LIGO or LISA. For negative values of the coupling constant, ghosts are known to arise, and we explicitly verify their appearance numerically. Our results are validated using both time evolution and frequency domain methods.

Anomalous thermodynamic properties in ferropericlase throughout its spin crossover transition

The thermodynamics properties of ferropericlase (Mg(1-x)Fe(x)O where x=0.1875) (Fp) throughout its spin crossover were investigated by first principles. Fp was treated as an ideal solid solution of pure high-spin and low-spin states. The Gibbs free energies of the pure states were addressed using the LDA+U method. A vibrational virtual-crystal model was developed to address the vibrational properties of the pure spin cases and used in conjunction with quasiharmonic theory to compute their vibrational free energies. The thermodynamics properties of Fp display significant anomalies that should be typical of spin crossover systems in general. In Fp, in particular, they are fundamental for understanding the state of earth's interior, where the pressure and temperature conditions of the crossover are realized.

The gross theory model for neutrino-nucleus cross-section

The nuclear gross theory, originally formulated by Takahashi and Yamada (1969 Prog. Theor. Phys. 41 1470) for the beta-decay, is applied to the electronic-neutrino nucleus reactions, employing a more realistic description of the energetics of the Gamow-Teller resonances. The model parameters are gauged from the most recent experimental data, both for beta(-)-decay and electron capture, separately for even-even, even-odd, odd-odd and odd-even nuclei. The numerical estimates for neutrino-nucleus cross-sections agree fairly well with previous evaluations done within the framework of microscopic models. The formalism presented here can be extended to the heavy nuclei mass region, where weak processes are quite relevant, which is of astrophysical interest because of its applications in supernova explosive nucleosynthesis.

Electron theoretical investigation of the stability of the B2-TiFe compound

The metastable phase diagram of the BCC-based ordering equilibria in the Ti-Fe system has been calculated using a truncated cluster expansion, through the combination of FP-LAPW and cluster variation method (CVM) in the irregular tetrahedron cluster approximation. The results are compared with phenomenological CVM assessments of the system and suggest that the value for the experimental formation enthalpy of the B2-TiFe compound should be significantly more negative than the currently assessed value.

Hemoglobin Regeneration Efficiency in Anemic Rats: Effects on Bone Mineral Composition and Biomechanical Properties

This study reports the effects of dietary iron (Fe) deficiency and recovery on bone mineral composition and strength in anemic rats submitted to a hemoglobin (Hb) repletion assay. Weanling male Wistar rats were fed a low-Fe diet (12 mg/kg) for 15 days followed by 2 weeks of Fe repletion with diets providing 35 mg Fe/kg as either ferrous sulfate (n = 8) or ferric pyrophosphate (FP; n = 12). At final day of each period (depletion and repletion), Fe-adequate animals were also euthanized. Iron status (blood Hb, Hb Fe pool, Hb regeneration efficiency), tibia mineral concentrations (Ca, Mg, Fe, Cu, and Zn) and biomechanical properties were evaluated. Iron-deficient rats had lower tibia Fe and Mg levels and bone strength when compared to controls. Yield load and resilience were positively related to tibia Mg levels (r = 0.47, P = 0.02 and r = 0.56, P = 0.004, respectively). Iron repletion did not recover tibia Mg concentrations impaired by Fe deficiency. Moreover, bone elastic properties were negatively affected by FP consumption. In conclusion, bone mineral composition and strength were affected by Fe deficiency, whereas dietary Fe source influenced tibia Mg and resistance in the period during which rats were recovering from anemia.

Iron bioavailability from ferric pyrophosphate in rats fed with fructan-containing yacon (Smallanthus sonchifolius) flour

The effects of inulin-type fructans (ITF)-containing yacon flour (YF) on Fe bioavailability from ferric pyrophosphate (FP) were evaluated in Fe-deficient rats using the Hb repletion efficiency (HRE) assay. Weanling male Wistar rats were fed a low-Fe diet (12 mg/kg) for 15 days followed by 2 weeks of Fe repletion with diets providing 35 mg Fe/kg as either ferrous sulphate (FS) or FP, supplemented with 7.5% ITF as either YF or Raftilose (RAF), a purified ITF. ITF increased caecal fermentation, whereas YF was more butyrogenic than RAF. ITF improved FIRE in FP-fed rats, and those fed YF had a higher relative biological value compared with those fed FP and RAF. Liver Fe was increased by ITF, but only YF led to values similar to those in the FS group. It is observed that ITF increased caecal fermentation and Fe bioavailability. These effects were more pronounced when YF was the ITF source. (C) 2010 Elsevier Ltd. All rights reserved.

Advice on exercise from a family physician can help sedentary patients to become active

Objectives: To test the effectiveness, in the setting of primary health care, of verbal advice on exercise from a family physician (FP) combined with supporting written information. Design: A controlled trial with subjects allocated to a control group or one of two intervention groups using a balanced design based on day of the week. Setting: Ten general practices in Perth, Western Australia. Subjects: All sedentary patients consulting an FP. Intervention: Verbal advice on exercise from the FP and a pamphlet on exercise mailed to the patient's home address within 2 days of his/her visit to the doctor. Main outcome measure: Level of physical activity at followup. Results: 6,351 adult patients attending an FP practice completed a screening questionnaire, and 763 sedentary adults were recruited to the project. The response to follow-up, via a postal survey at 1, 6, and 12 months after the index consultation was 70%, 60%, and 57%, respectively. At 1 month a subsample of the control and intervention subjects were contacted for a telephone interview to verify self-reported levels of activity (n = 136). Treating all nonresponders as sedentary, at 1 month significantly more subjects in the combined intervention groups reported doing some physical activity (40%) compared with the control group (31%). Similarly, at 6 months, 30% of the control group and 38% of the combined intervention groups were now active. There was very little change at followup at 12 months (31% control and 36% intervention groups, respectively). Conclusion: A simple intervention aimed at the promotion of physical activity to sedentary patients in general practice can help reduce inactivity.

Tailored advice on exercise - Does it make a difference?

Objectives: A controlled trial to compare the effectiveness of verbal advice from a family physician (FP) combined with either standard or tailored written information on physical activity in increasing the levels of physical activity in sedentary patients. Design: Sedentary patients (n = 763) were recruited through ten family practices and allocated to a control group or one of two intervention groups, Brief advice on physical activity was given by the FP during the consultation and either a standard or tailored pamphlet was mailed to the home address of patients assigned to the intervention groups within two days of their visit to the FP. Results: The response to follow-up, via a postal survey at one, six, and twelve months after the index consultation was 70%, 60%, and 57%, respectively. Treating all nonresponders as sedentary, the results revealed that although more tailored subjects reported some physical activity at each follow-up compared with the standard group, these differences were not significant, Furthermore, there was no significant difference in movement across the stages of readiness to exercise at follow-up between subjects in the tailored group who received material targeting their current stage (precontemplation or contemplation) and the standard group who received generic material that addressed both stages. Conclusion: These findings do not concur with the results from previous research in the areas of nutrition and smoking cessation where additional benefits were seen with a tailored intervention. Future research on the application of the principles of tailoring to the promotion of physical activity should focus on identifying which, if any, physical, social, psychological or environmental variables should be addressed to produce improved outcomes over and above the effects of well designed generic materials.
