Doce notas introductoras al concepto de ideología
Bonetti,José Andrés;
Revista de Filosofía , 2004,
Abstract: this article studies the semantic history of the concept of ideology, from its initial meaning as science of ideas, according to destutt de tracy, to that of mystification of reality, according to marx, who searched for, as those of the vienna circle after him, a criteria of demarcation to differentiate between science and that which is a falsification of reality (discourse without empirical content or metaphysics, according to neo-positivists). marx thought he had found it in the study of the figures of ideology (philosophy, religion, and classical political economy) which do not have a history and which need to be purified to build true science: history itself, as rerum gestarum.

Abstract: For effect of CE 853/04 Regulation slaughterhouses authorized as low-capacity establishments under 91/497/CEE directive and 286/94 Decree, had to obtain the approval by 31/12/2009 to continue operating. This work illustrates the experience of the Veterinay Department of Bergamo Local Sanitary Authority about adjustment of low-capacity slaughterhouses to the requirements for by 852/04 and 853/04 Regulation. Here it’s illustrated the activity of the Veterinary Department and the evolution of slaughterhouses reality form 2006 to 2009. From a starting number of 154 low-capacity slaughterhouses operating in 2006, among which none conforming to the European Regulation, at the end of the adjustment activities we’ve reached the number of 85 approved slaughterhouses. To the significant reduction of the number of the establishments we associate the clear improvement of the hygiene standards, thanks to the punctual respect of the structural and functional requirements provided for by Regulations
Zero Field precession and hysteretic threshold currents in spin torque oscillators with tilted polarizer
Yan Zhou,S. Bonetti,C. L. Zha,Johan Akerman
Physics , 2008, DOI: 10.1088/1367-2630/11/10/103028
Abstract: Using non-linear system theory and numerical simulations we map out the static and dynamic phase diagram in zero applied field of a spin torque oscillator with a tilted polarizer (TP-STO).We find that for sufficiently large currents, even very small tilt angles (beta>1 degree) will lead to steady free layer precession in zero field. Within a rather large range of tilt angles, 1 degree< beta <19 degree, we find coexisting static states and hysteretic switching between these using only current. In a more narrow window (1 degree
Huge Seebeck coefficients in non-aqueous electrolytes
M. Bonetti,S. Nakamae,M. Roger,P. Guenoun
Physics , 2011, DOI: 10.1063/1.3561735
Abstract: The Seeebeck coefficients of the non-aqueous electrolytes tetrabutylammonium nitrate, tetraoctylphosphonium bromide and tetradodecylammonium nitrate in 1-octanol, 1-dodecanol and ethylene-glycol are measured in a temperature range from T=30 to T=45 C. The Seebeck coefficient is generally of the order of a few hundreds of microvolts per Kelvin for aqueous solution of inorganic ions. Here we report huge values of 7 mV/K at 0.1M concentration for tetrabutylammonium nitrate in 1-dodecanol. These striking results open the question of unexpectedly large kosmotrope or "structure making" effects of tetraalkylammonium ions on the structure of alcohols.

Considerations about the Polyssemy of Meanings in a Daily Newspaper: a essay about the press
Bonetti, Alexandre
Athenea Digital , 2008,
Abstract: Are the mass media ideologically dominant, or is their unfettered polysemy a constructive force in modern society? From the perspective of Constructivist Social Psychology we argue that the daily newspaper is a mosaic in which promotes multiple dialogues about, and representations of, the news. A newspaper is dialogic in three senses: it is a sounding-board for multiple voices, from various sources and with correspondingly various positions on the news; it is a social actor, with its own voice and position about what it reports; and it is a forum for dialogue with readers, who are active co-authors of the stories that they read. In other words, the newspaper is a channel for the expression of the hegemonic struggles of a given place and time.
Effectiveness of a 'Global Postural Reeducation' program for persistent Low Back Pain: a non-randomized controlled trial

Abstract: According to inclusion and exclusion criteria, 100 patients with a primary complaint of persistent LBP were enrolled in the study: 50 were allocated to the GPR group and 50 to the SE group. Primary outcome measures were Roland and Morris Disability Questionnaire (RMDQ) and Oswestry Disability Index (ODI). Secondary outcome measures were lumbar Visual Analogue Scale (VAS) and Fingertip-to-floor test (FFT). Data were collected at baseline and at 3/6 months by health care professionals unaware of the study. An intention to treat approach was used to analyze participants according to the group to which they were originally assigned.Of the 100 patients initially included in the study, 78 patients completed the study: 42 in the GPR group and 36 in the SE group. At baseline, the two groups did not differ significantly with respect to gender, age, BMI and outcome measures. Comparing the differences between groups at short- and mid-term follow-up, the GPR group revealed a significant reduction (from baseline) in all outcome measures with respect to the SE group.The ordered logistic regression model showed an increased likelihood of definitive improvement (reduction from baseline of at least 30% in RMDQ and VAS scores) for the GPR group compared to the SE group (OR 3.9, 95% CI 2.7 to 5.7).Our findings suggest that a GPR intervention in subjects with persistent LBP induces a greater improvement on pain and disability as compared to a SE program. These results must be confirmed by further studies with higher methodological standards, including randomization, larger sample size, longer follow-up and subgrouping of the LBP subjects.NCT00789204Approximately 70-85% of individuals will experience low back pain (LBP) during their lifetime, and over 80% of them will report recurrent episodes [1]. It is estimated that 80-90% of subjects will recover within 6 weeks, regardless of the type of treatment [1]; however, 5-15% will develop chronic LBP [1]. LBP is defined as pain and discomfor

Abstract: purpose: report the characteristics of cryopreserved semen from a cohort of male cancer patients, attitudes towards cryopreservation and outcomes of semen samples based on a 12-year cryopreservation program. material and methods: data from 98 male cancer patients whose sperm samples were banked were evaluated. demographic parameters, semen characteristics, destination of sperm banked samples and questionnaires answered by the patients regarding cryopreservation time were evaluated. results: the cancer diagnoses were testicle (56.1%), prostate (15.3%), hodgkin’s lymphomas (9.2%), non-hodgkin’s lymphomas (7.1%), leukemia (3.1%) and other malignancies (9.2%). the patients with testicular cancer presented lower sperm concentration (p < 0.001); however, there were no differences with the percentage of normozoospermic patients among cancer type groups (p = 0.185). a shorter time between cancer diagnosis and sperm banking was observed for testicular and prostate cancer patients (p < 0.001). most of the patients (89.5%) favored sperm banking as a fertility preservation method. conclusions: although less than 20% of banked sperm samples were disposed of, the majority of patients related sperm banking with safe for fertility preservation. our results show that all male cancer patients of reproductive age facing cancer treatment could be offered sperm banking.
Spin-torque oscillator based on tilted magnetization of the fixed layer
Yan Zhou,C. L. Zha,S. Bonetti,J. Persson,Johan Akerman
Physics , 2008,
Abstract: The spin torque oscillator (STO), where the magnetization of the fixed layer is tilted out of the film plane, is capable of strong microwave signal generation in zero magnetic field. Through numerical simulations of the Landau-Lifshitz-Gilbert-Slonczewski equations, within a macro-spin approximation, we study the microwave signal generation as a function of drive current for two realistic tilt angles. The tilt magnetization of the fixed layer can be achieved by using a material with high out-of-plane magnetocrystalline anisotropy, such as L10 FePt.
Electronic Transport in Underdoped YBCO Nanowires: Possible Observation of Stripe Domains
J. A. Bonetti,D. S. Caplan,D. J. Van Harlingen,M. B. Weissman
Physics , 2004,
Abstract: We have measured the transport properties of a series of underdoped YBa2Cu3O7 nanowires fabricated with widths of 100-250 nm. We observe large telegraph-like fluctuations in the resistance between the pseudogap temperature T* and the superconducting transition temperature Tc, consistent with the formation and dynamics of a domain structure such as that created by charge stripes. We also find anomalous hysteretic steps in the current-voltage characteristics well below Tc.
