Exposure to Mycotoxin-Mixtures via Breast Milk: An Ultra-Sensitive LC-MS/MS Biomonitoring Approach
Authors: Braun Dominik , Ezekiel Chibundu N. , Marko Doris , Warth Benedikt
Published: January 2020

Exposure to natural food contaminants during infancy may influence health consequences later in life. Hence, breast milk may serve as a vehicle to transport these contaminants, including mycotoxins, from mothers to their infants. Analytical methods mostly focused on single exposures in the past, thus neglecting co-occurrences and mixture effects. Here, we present a highly sensitive multi-biomarker approach by a sophisticated combination of steps during sample preparation including QuEChERS extraction followed by SPE cleanup and utilizing stable isotopes for compensating challenging matrix effects. The assay was validated in-house, reaching limits of detection (LOD) for all 34 analytes in the range of 0.1 to 300 ng/L with satisfying extraction efficiencies (75 - 109%) and stable intermediate precisions (1 - 18%) for most analytes. Compared to our first published multi-mycotoxin method LODs were decreased by a factor of 2-60x enabling the assessment of chronic low-dose exposures. The new method was applied to a small set of Nigerian breast milk samples to compare results with already published data. Concentration levels of samples determined to be contaminated before could be confirmed. The newly investigated alternariol monomethyl ether (AME) was found for the first time in this biological fluid at concentrations up to 25 ng/L. Moreover, in a pooled Austrian sample trace amounts of multiple mycotoxins confirmed co-occurrence and exposure even in countries with high food safety standards. In conclusion, the method facilitates the determination of mycotoxins at ultra-trace levels in breast milk, enabling the generation of occurrence data necessary for comprehensive co-exposure assessment.

Published: January 2020

The use of photodynamic therapy (PDT) against cancer has received increasing attention overthe recent years. However, the application of the currently approved photosensitizers (PSs) is somehow limited by their poor aqueous solubility, aggregation, photobleaching and slow clearance from the body. To overcome these limitations, there is a need for the development of new classes of PSs with ruthenium(II) polypyridine complexes currently gaining momentum. However, these compounds generally lack significant absorption in the biological spectral window, limiting their application to treat deep-seated or large tumors. To overcome this drawback, ruthenium(II) polypyridine complexes designed in silico with (E,E’)-4,4´-bisstyryl 2,2´-bipyridine ligands showed impressive 1- and 2-Photon absorption up to a magnitude higher than the ones published so far. While non-toxic in the dark, these compounds were found phototoxic in various 2D monolayer cells, 3D multicellular tumor spheroids and be able to eradicate a multiresistant tumor inside a mouse model upon clinically relevant 1-Photon and 2 Photon excitation.

Kinetic target-guided synthesis represents an efficient hit-identification strategy, in which the protein assembles its own inhibitors from a pool of building blocks via an irreversible reaction. Herein, we pioneered an in situ Ugi reaction for the identification of novel inhibitors of a model enzyme and binders for an important drug target, namely, the aspartic protease endothiapepsin and the bacterial ß-sliding clamp DnaN, respectively. Highly sensitive mass-spectrometry methods enabled monitoring of the protein-templated reaction of four reaction partners, which occurred in a background-free manner for endothiapepsin or with a clear amplification of two binders in the presence of DnaN. The Ugi products show low micromolar activity on endothiapepsin or moderate affinity for DnaN. We succeeded in expanding the portfolio of chemical reactions and biological targets and demonstrated the efficiency and sensitivity of this approach, which can find application on any drug target.
Cellulose Hydrogels for Rapid Dye Removal from Water
Authors: Harris Justin , McNeil Anne
Published: January 2020

Clean water has become increasingly difficult to access due to the environmental discharge of pollutants. One potential solution is to develop materials that can efficiently remove pollutants from water sources through adsorption. Hydrogels have been explored for water remediation, but they often require long times to reach high levels of adsorption. To overcome this limitation, we developed a quick and locally formed hydrogel that adsorbs a common cationic dye during gel formation. Specifically, we demonstrate that hydrogels derived from cellulose – a renewable, non-toxic, and biodegradable resource – can efficiently remove methylene blue from water within seconds. We found that both sulfated cellulose nanofibers and sulfated wood pulps form localized gels when mixed with solutions containing a soluble, cationic cellulose derivative and the cationic dye. Overall, these localized hydrogels may be promising materials for remediating other water pollutants with further functionalization.

Published: January 2020

The work covers the welding of thermoplastic polymethyl methacrylate (PMMA) and concerns the assessment of the impact of the main welding parameters on joint strength. The strength test of welded joints made of thermoplastic material was carried out. The aim of the study was to determine the influence of the main technological parameters of welding, such as: temperature and welding speed, gas stream output, filler rod pressure, diameter and type of hot air gun nozzle on the strength of the obtained joint. The method of sample preparation and testing was performed in accordance with the guidelines of PN-EN 12814-2: 2002 "Tests of welded joints in semi-finished products made of thermoplastics ‒ Part 2: Tensile test". Visual evaluation of welded samples and analysis of results obtained from the tensile test made it possible to draw conclusions about the influence of selected welding parameters on joint strength. The decisive influence on the strength of joints was caused by welding defects, in the form of lack of side wall fusion and porosity.

The issue raised in the text concerns the role that German textbooks for religious instruction play in shaping the identity of a child from the initial classes. The first part defines the key concept: religious identity. Modern contexts of religious socialization and the resulting challenges to the educational process were also recalled. In the second part, based on the results of the analysis of textbooks, the conclusion about the positive meaning of these books was formulated as a means of supporting the development of the individual and social aspect of the child’s religious identity and shaping a reflective and at the same time affirmative attitude towards religion.
Troska o świat i zadanie jego wspólnej przebudowy, czyli o Korczakowskiej uwspólniającej utopii w działaniu
Authors: Starego Karolina
Published: January 2020

The aim of this paper is to reconstruct Korczak’s notion of “utopia in action”. The notion is based on the philosophy of education concerned with creating of what is common. In this analysis I leave aside Korczak’s “paidocentrism” and focus on the communal elements in his thought – such as the care for the world that is also a call for its shared reconstruction, and the ontological force of love for the world and the people that populate it. Such an interpretation of Korczak’s thought allows it to become a topical alternative for the essentialist, antagonistic and exclusive ideas concerning community education.
Novel Approach for Teaching English Language using Emerging Information and Communication Technologies for Visual Impairment Students
Authors: Cardenas Jorge , Inga Esteban
Published: January 2020

Nowadays, Higher Education Institutions (HEI) need to be more inclusive from the methodological vision appropriate used in the classroom. Visual impairment students (VIS) become a challenge for teachers who look for incorporating different learning environments. This challenge increases when teaching and learning process to VIS is related to the English language; due to the absence of educational didactic resources available at the school and the lack of knowledge of appropriate teaching methodologies and strategies to develop the different language skills: listening, speaking, reading and writing that go with the educational process in the acquisition of the English language. In accordance with this problem, this research proposes a novel methodological strategy, based on the usage of meaningful learning with emerging technologies as a main guide for students with visual impairment. Thus, the road map of good practices in the use of this methodology will allow establishing a clear process to achieve students’ active, meaningful and autonomous participation, using the least time in the teaching-learning process of the English language.

Authors: GARCIA TORRES EDWIN MARCELO
Published: January 2020

The intelligent microgrids are an efficient alternative, which allows to supply the demand decreasing the losses of the electrical system and at the same time; the environment and the consumers are the main beneficiaries. This article develops a heuristic based on an energy management model based on the real price of electricity, which will allow end users to encourage the implementation of a policy of response to demand, in order to optimize their consumption, for which a micro smart grid is analyzed, with conventional and non-conventional renewable generation, In addition, a mechanism of "real energy price" will be implemented as a policy of response to demand, with the aim of optimizing the costs of energy that will be transferred to users depending on the stratum to which it belongs, these costs will have a short-term horizon with hourly intervals, achieving a reduction in the purchase of energy from the system

Published: January 2020

In the contemporary research article we have performed a numerical investigation of the non-Newtonian fluid flow through a rectangular channel with a fixed solid screen devoted at the angles 100 to 450 degrees. We have employed the power-law model for shear thickening and shear thinning fluids with the high Reynolds number between 1000 and 10,000. The obstacle has been solved by putting in the Galerkinâ€™s least square strategy of the finite element method and the procedure has been carried out utilizing the commercial software COMSOL Multiphysics. Various flow properties such as 'maximum flow rate' and 'pressure' have been discussed in the terms of the Reynolds number and also using the linear and quadratic regressions in order to establish the relationship between them for the future analysis. Moreover the impact of turning screen in the shape of increment in the maximum flow rate and pressure is checked in terms of Reynolds number andÂ  Satisfactory results are gained in comparison with the results available in the literature.
Some Results on C-retractable Modules
Authors: Diallo Abdoul Djibril , Diop Papa Cheikhou , Barry Mamadou
Published: January 2020

An R-module M is called c-retractable if there exists a nonzero homomorphism from M to any of its nonzero complement submodules. In this paper, we provide some new results of c- retractable modules. It is shown that every projective module over a right SI-ring is c-retractable. A dual Baer c-retractable module is a direct sum of a Z2-torsion module and a module which is a direct sum of nonsingular uniform quasi-Baer modules whose endomorphism rings are semi- local quasi-Baer. Conditions are found under which, a c-retractable module is extending, quasi-continuous, quasi-injective and retractable. Also, it is shown that a locally noetherian c-retractable module is homo-related to a direct sum of uniform modules. Finally, rings over which every c-retractable is a C4-module are determined.

Using Fractal Calculus to Express Electric Potential and Electric Field in Terms of Staircase and Characteristic Functions
Authors: Delfan Nasibeh , Pishkoo Amir , Azhini Mahdi , Darus Maslina
Published: January 2020

The Dirac Delta function is usually used to express the discrete distribution of electric charges in electrostatic problems. The integration of the product of the Dirac Delta function and the Green functions can calculate the electric potential and the electric field. Using fractal calculus, characteristic function, $\chi_{C_{n}}(x)$, as an alternative for dirac delta function is used to describe Cantor set charge distribution which is typical example of a discrete set. In these cases we deal with $F^{\alpha}$-integration and $F^{\alpha}$-derivative of the product of characteristic function and function of staircase function, namely $f(S^{\alpha}_{C_{n}}(x))$, which lead to calculation of electric potential and electric field. Recently, a calculus based fractals, called F$^{\alpha}$-calculus, has been developed which involve F$^{\alpha}$-integral and F$^{\alpha}$-derivative, of orders $\alpha$, $0<\alpha<1$, where $\alpha$ is dimension of $F$. In F$^{\alpha}$-calculus the staircase function and characteristic function have special roles. Finally, using COMSOL Multiphysics software we solve ordinary Laplace's equation (not fractional) in the fractal region with Koch snowflake boundary which is non-differentiable fractal, and give their graphs for the three first iterations.
On Strong Resolving Domination in the Join and Corona of Graphs
Authors: Monsanto Gerald Bacon , Acal Penelyn L. , Rara Helen M.
Published: January 2020

Let G be a connected graph. A subset S \subseteq V(G) is a strong resolving dominating set of G if S is a dominating set and for every pair of vertices u,v \in V(G), there exists a vertex w \in S such that u \in I_G[v,w] or v \in I_G[u,w]. The smallest cardinality of a strong resolving dominating set of G is called the strong resolving domination number of G. In this paper, we characterize the strong resolving dominating sets in the join and corona of graphs and determine the bounds or exact values of the strong resolving domination number of these graphs.

Published: January 2020

This work is part of a megaproject that seeks to isolate microalgae of the Chlorophyta division native to Norte de Santander and identify their potential applications such as lipid production to be used as biofuel. Here we present the isolation of 11 microalgae strains from the Chlorophyta division found in two different wastewater environments. The collected strains were cultivated in selective media and purified through serial dilutions, depletion culture, and application of penicillin and gentamicin. Biomass production was evaluated and two strains were selected: CHL1 (Chlorella sp.) and DES1 (Desmodesmus sp.). The strains were cultivated on wastewater and PCG media (control), and their biomass concentration and lipid content were measured. Both strains reached similar biomass concentrations compared to their respective controls (CHL1 PCG 1.5 mg/L ± 0.035 mg/L, CHL1 AR 1.68 mg/L ± 0.036, DES1 PCG 1.66 mg/L ± 0.007, DES1 AR 2 mg/L ± 0.03) and their lipid content was slightly higher compared to their controls. The results show that the isolated and evaluated strains may have potential to be lipid producers, since their environmental and nutritional conditions have not been modified yet and adaptation may improve the production yield of lipids.
Determination of well-drainage area for power-law fluids by transient pressure analysis
Authors: Escobar Freddy-Humberto , Vega Laura-Jimena , Bonilla Luis-Fernando
Published: January 2020

Since conventional oil is almost depleted, oil companies are focusing their efforts on exploiting heavy oil reserves. A modern and practical technique using the pressure and pressure derivative, log-log plot for estimating the well-drainage area in closed and constant-pressure reservoirs, drained by a vertical well is presented by considering a non-Newtonian flow model for describing the fluid behavior. Several synthetic examples were presented for demonstration and verification purposes.Such fluids as heavy oil, fracturing fluids, some fluids used for Enhanced Oil Recovery (EOR) and drilling muds can behave as either Power-law or Bingham, usually referred to as the non-Newtonian fluids. Currently, there is no way to estimate the well-drainage area from conventional well test analysis when a non-Newtonian fluid is dealt with; therefore, none of the commercial well test interpretation package can estimate this parameter (drainage area).
Deconvolution-type imaging condition effects on shot-profile migration amplitudes
Authors: Vivas-Mejía Flor-A. , González-Alvarez Herling , Jaimes-Osorio Ligia-E. , Espindola-López Nancy
Published: January 2020

Amplitude preservation in Pre-Stack Depth Migration (PSDM) processes that use wavefield extrapolation must be ensured – first, in the operators used to continue the wavefield in time or depth, and second, in the imaging condition used to estimate the reflectivity function. In the later point, the conventional correlation-type imaging condition must be replaced by a deconvolution-type imaging condition. Migration performed in common-shot profile domain obtains the final migrated image as the superposition of images resulting of migrate each shot separately. The amplitude obtained in a point of the migrated image corresponds to the sum of the reflectivities for each shot which has illuminated such point, along the angles determined by the velocity model and the positions of the source and the receiver. The deeper the reflector, the lower the amplitude of the illumination field will be. As result, the correlation-type imaging condition produces images with an unbalanced amplitude decrease with depth. A deconvolution-type imaging condition scales the amplitudes through a correlation, using the weighting function dependent on the spectral density or the illumination of the downgoing wave field. In this article, two possible scaling functions have been used in the case of a single shot. In the case of data with multiple shots, five scaling possibilities are presented with the spectral density or the illumination function. The results of applying these imaging conditions to synthetic data with multiple shots show that the values of the amplitude in the migrated images are influenced by the coverage of the common midpoint, compensating this effect only in one of the imaging conditions described. Numerical experiments with synthetic data generated using Seismic Unix and the Sigsbee2a data are presented, highlighting that in velocity fields with strong vertical and lateral velocity variations, the balance of the amplitudes of the deep reflectors relative to the shallow reflectors is strongly influenced by the imaging condition applied.
Determination of molecular masses for petroleum distillates by simualted distillation
Authors: Carbognani Lante
Published: January 2020

Determination of Molecular Mass (MM) for petroleum distillates is explored for selected samples viaHigh Temperature Simulated Distillation (HTSD). MM is determined as a by-product from routineHTSD carried out using open wall capillary columns coated with apolar stationary phases. No samplepre-separation into hydrocarbon group-types is required. Determined MM values were validated with resultsachieved via correlations based on specific gravity and refractive index. Furthermore, determined MM withthe former methodologies were found to match mass spectrometric determinations carried out for the basicpolar components present within the studied samples. Moreover, HTSD analyzed petroleum distillates areproposed as more representative calibration standards for size exclusion chromatographic separations, thusopening the feasibility of extrapolating MM determination for non volatile petroleum residua.
Comparison of potential environmental impacts on the production and use of high and low sulfur regular diesel by life cycle assessment
Authors: Martinez-Gonzalez Aldemar , Casas-Leuro Oscar-Mauricio , Acero-Reyes Julia-Raquel , Castillo-Monroy Edgar-Fernando
Published: January 2020

This paper provides a comparative analysis using the concept of life cycle assessment (LCA), between high-sulfur (3000 ppm) and low-sulfur diesel (500 ppm) diesel. The comparative LCA considers the stages of production, transport and oil refining , as well as the transport of refined products and their respective end use. This last stage of the life cycle is important for the analysis of potential environmental impacts, due to sulfur oxide (SOx) emissions, which contribute to the formation of acid rain, damage air quality and the ecosystem (land and water acidification), causing gradual damage to human health and the environment. Therefore, comparative LCA identifies critical points from the environmental perspective, weighing the contributions of pollutants (NO2, CH4 and CO2) known as greenhouse gases (GHG) and criteria pollutants (CO, SOX, NOX, VOC's and PM). Simapro 7.2® was used to simulate and evaluate potential environmental impacts generated during the production and use by end consumers of the two fossil fuels. In order to evaluate the impact categories, two methods available in said calculation tool were selected: the first is the IPCC-2007 (GWP-100years), which estimates the carbon footprint and the contributions of each stage of the production chain to the "Global Warming" effect. The second method of evaluation is the Impact 2002+, which assesses the various contributions to the categories of toxicity to "Human Health", "Ecosystem Quality", "Climate Change" and "Depletion of Natural Resources". Thus, the preliminary results of comparative LCA show a slight increase in the carbon footprint (total emissions of CO2 equivalent in the productive chain) of low-sulfur diesel, approximately 3.8% compared to high-sulfur diesel, as a result of the increased emissions generated by the operation of the hydrogenation plant. However, low-sulfur diesel achieves a significant reduction of about 80% in comparison with high-sulfur diesel, in terms of damage to "Human Health" and "Ecosystem Quality". On the contrary, there was an increase of 2% and 6% in the categories of "Climate Change" and "Depletion of Natural Resources", respectively. Finally, despite the minor increase in the carbon footprint, although with remarkable reductions in "Ecosystem Quality" and "Human Health", the production and use of low-sulfur diesel has a single score of environmental impact equivalent to 0.23 milli points (mPt) compared to the single score obtained by high-sulfur diesel of 1.23 (mPt).
Caractéristiques organisationnelles qui influencent le renforcement des capacités en évaluation chez les organismes communautaires du Québec : une recension des écrits
Authors: Buetti David , Bourgeois Isabelle , Savard Sébastien
Published: January 2020

Few studies have conceptualized evaluation capacity for community organizations (COs), and even fewer in the specific context of COs in Québec. The objective of this article, therefore, is twofold: 1) to identify barriers to, and opportunities for, building evaluation capacity among OCs and 2) to verify the extent to which an existing conceptual framework of organizational evaluation capacity established by Isabelle Bourgeois and J. Bradley Cousins could be useful in its current form for understanding the evaluation capacity needs of COs in Québec. We first conducted a review of the scientific literature to identify the barriers and opportunities for evaluation capacity building in OCs, and analyzed the results of the literature review against the conceptual framework. Our results point to the fact that Bourgeois and Cousins’ framework is appropriate for understanding the key factors influencing the capacity to do and to use evaluations among OCs. Additional efforts would, however, be necessary to improve the framework’s compatibility with the practices and values of COs in Québec.Les capacités en évaluation sont peu étudiées et encore moins conceptualisées en fonction du contexte particulier des organismes communautaires (OC) du Québec. Ainsi, l’objectif de cet article est double : 1) identifier chez les OC les barrières et les éléments qui facilitent le renforcement des capacités en évaluation et 2) vérifier dans quelle mesure un cadre conceptuel établi par Isabelle Bourgeois et J. Bradley Cousins pourrait s’avérer propice dans sa forme actuelle pour l’analyse des capacités en évaluation du milieu communautaire québécois. Nous avons d’abord identifié les barrières et les éléments qui facilitent le renforcement des capacités en évaluation des OC à partir d’une recherche documentaire d’articles scientifiques pertinents pour ensuite effectuer une analyse à partir du cadre conceptuel choisi. Nos résultats démontrent que le cadre conceptuel de Bourgeois et Cousins est pertinent pour répertorier les facteurs clés influençant la capacité à effectuer et à utiliser l’évaluation chez les OC. Des efforts supplémentaires seraient toutefois nécessaires pour améliorer la compatibilité du cadre conceptuel avec les pratiques et valeurs du milieu communautaire québécois.
Effect off host plant species on immature development and adult size of Neoleucinodes elegantalis (Guenée 1854) (Lepidoptera: Crambidae)

Published: January 2020

Plantas hospedeiras afetam vários traços de insetos. As causas dessas mudanças são relacionadas à adequação das plantas, em relação a seus caracteres físicos e químicos e suas consequências fisiológicas nos insetos. Muitos dos fatores que afetam o desempenho dos insetos são caracteres ecológicos e nutricionais de plantas. Durante o estágio larval, a variação no consumo de alimentos reverbera na morfologia e desempenho geral do adulto, especialmente em insetos holometábolos. Um balanço entre os traços da história de vida frente a diferentes hospedeiros é comum, pois mudanças no tempo de desenvolvimento larval influenciam no tamanho. Para investigar o papel da planta hospedeira no estágio larval e como ela reflete sobre o tamanho adulto, examinamos a história de vida imatura da broca Neoleucinodes elegantalis (Lepidoptera: Crambidae) em quatro plantas hospedeiras. O desenvolvimento larval e a taxa de crescimento são afetados pela planta hospedeira, mas o tamanho da pupa é igual para todos os hospedeiros. A taxa de crescimento das fêmeas é maior que a dos machos em todos os hospedeiros, e nos hospedeiros foi maior em Solanum gilo do que Lycopersicum esculentum, mas igual em insetos crescidos em S. melongena e Capsicum annuum. Fatores que afetam essas diferenças foram discutidos.

Objective Apolipoprotein E (ApoE) is mainly synthesized in the liver. So far, it is unknown the relationship among APOE gene polymorphisms and WML, brain atrophy. Therefore, the aim of the study was to assess the associations of APOE gene polymorphisms in patients with WML and brain atrophy.Methods A total of 58 patients with WML, 128 patients with brain atrophy, 112 patients with co-occurrence of WML and brain atrophy and 95 healthy elderly volunteers were recruited from Renmin Hospital of WuHan University.Results Allele E3 was the most common allele. The alleles E2 had significantly higher levels of ApoB and lower age in WML group. The alleles E2 was associated with the lower level of ApoB, LDL-Ch, TCh, and sdLDL in co-occurrence group. The E3/E3 genotype has higher level of sdLDL, but lower age and female frequency in WML. The E3/E4 genotype had higher level of TG, but lower age in WML. Gender, Age, E2, Hyperhomocysteinemia and UA were also significantly associated with disease progression.Conclusion This study found that clinical data, lipids and metabolic complications were closely related to ApoE genotypes and alleles, and also disease progression and type.
Hétérotopies de l'apersonne. Une lecture de L'Acacia de Claude Simon
Authors: Crivella Giuseppe
Published: January 2020

Dans cet article, nous proposons d'analyser les structures textuelles qui soutiennent le récit "autobiographique" de Claude Simon. Notre analyse vise à montrer que l'écriture développée par Simon dans un roman comme L'Acacia (1989) rompt et renverse chaque élément spécifique à l'autobiographie. Cette technique narrative est donc en lien avec les théories exprimées par Blanchot et Foucault dans des travaux comme L'Ordre du discours ou Une voix venue d'ailleurs.
Transfiguration et critique : Foucault, Baudelaire et l’ontologie du présent
Authors: Cremonesi Laura
Published: January 2020

De manière quelque peu surprenante, la figure de Charles Baudelaire apparaît au cœur de l’écrit de Michel Foucault consacré aux Lumières et à la Réponse de Kant à la question : Was ist Aufklärung? Foucault s’appuie sur Le peintre de la vie moderne de Baudelaire pour caractériser celle qui, à son avis, doit être considérée comme l’attitude de la modernité. Dans sa description du travail du dessinateur Constantin Guys, Baudelaire aurait capturé le trait principal de cette attitude : «À l’heure où le monde entier entre en sommeil, il se met, lui, au travail, et il le transfigure. Transfiguration qui n’est pas annulation du réel, mais jeu difficile entre la vérité du réel et l’exercice de la liberté. […] Pour l’attitude de modernité, la haute valeur du présent est indissociable de l’acharnement à l’imaginer, à l’imaginer autrement qu’il n’est et à le transformer non pas en le détruisant, mais en le captant dans ce qu’il est. La modernité baudelairienne est un exercice où l’extrême attention au réel est confrontée à la pratique d’une liberté qui toute à la fois respecte ce réel et le viole». La communication consistera dans un commentaire de ce texte, afin de montrer que l’idée de « transfiguration », qui joue un rôle central dans ce passage, peut être utilisée pour mieux comprendre l’idée foucaldienne de critique : une description qui capte les déterminations historiques qui ont constitué notre présent (à travers des recherches archéologiques et généalogiques) et, en même temps, montre les possibilités ouvertes de transformation et d’inauguration de nouveauté (à travers l’ontologie historique du présent). Au cœur de la critique comme tâche de la philosophie, on trouve chez Foucault, à coté de Kant, la figure littéraire de Baudelaire.
