Recently, medicinal and aromatic plants have received much attention in several fields such agroalimentary, perfumes, pharmaceutical industries and natural cosmetic products. The consumption of herbal medicines is widespread and is continuously increasing worldwide. Although, secondary metabolites in the medicinal and aromatic plants were fundamentally produced by genetic processing but, their biosynthesis is strongly influenced by environmental factors. Salinity is one of the major factors that affect essential oil biosynthesis and secretion (Heuer et al. 2002). In Tunisia, salt-affected soils cover about 10% of the total area of the country. Salinity led to biochemical disorders and can change plant behaviour regarding the biosynthesis of primary and secondary metabolites. Among all the secondary metabolites synthesized by plants, phenolic compounds are some of the most widespread. In this context, this research evaluated the effect of salinity on total and individual polyphenols contents as well as the antioxidant activities of fennel (Foeniculum vulgarae Mill.) seeds of two geographic origins, Tunisia (TFS) and Egypt (EFS). This plant is one of the most common aromatics in the Mediterranean kitchen. Plants were treated with different concentrations of NaCl treatment: 0, 50, and 75 mmoL. Plant growth was significantly reduced with the severity of saline treatment. This also caused important reductions in the seed yield and yield components. Besides, total polyphenol content was higher in treated seeds, and salinity improved the amount of individual phenolic compounds. Moreover, antioxidant activities of the extracts were determined by four different test systems, namely 2,2-diphenyl-1-picrylhydrazyl, β-carotene/linoleic acid chelating, and reducing power assays. The highest antioxidant activities were reveled in severe stressed plants for both TFS and EFS. In this case, fennel seeds produced under saline conditions may function as a potential source of antioxidant compounds, which could support the utilization of this plant in a large field of applications such as food industry.

My article looks at two recent Asian American texts written in the first-person plural – namely Julie Otsuka’s The Buddha in the Attic (2011) and Chang-rae Lee’s On Such a Full Sea (2014). My main goal is to show that the ambiguities and tensions generated by we narration in these two Asian American novels prove particularly apt when it comes to calling into questions essentialist views concerning the anatomy of community-building. But these two we texts are particularly interesting at a theoretical level, in that they help us challenge the orthodoxies of traditional narrative theory– among which Gérard Genette’s all-too-rigid distinction between the homo- and heterodiegetic levels in a text, or the generalized assumption, which has been notably challenged by Mieke Bal, that every act of story-telling is necessarily indebted to ‘a’ narrator, and a narrator of anthropomorphic standards at that.

The Büchi-Bruyère theorem states that a multidimensional set of non-negative integers is b-recognizable if and only if it is b-definable. This result is a powerful tool for showing that many properties of b-automatic sequences are decidable. Going a step further, first-order logic can be used to show that many enumeration problems of b-automatic sequences can be described by b-regular sequences. The latter sequences can be viewed as a generalization of b-automatic sequences to integer-valued sequences. These techniques were extended to two wider frameworks: U-recognizable multidimensional sets of non-negative integers and multidimensional beta-recognizable sets of reals. In the second case, real numbers are represented by infinite words, and hence, the notion of beta-recognizability is defined by means of Büchi automata. Again, logic-based characterizations of $U$-recognizable (resp. beta-recognizable) sets allows us to obtain various decidability results. The aim of this chapter is to present a survey of this very active research domain. [less ▲]

Based on the case study of Jeanne, the objective of this article is to study patterns of anorexic people’s specific subjectivity. We seek to identify, in a first-person perspective, the core vulnerability features of anorexic existence, beyond the dimension of food alone. The identification of a psychopathological structure results in a better understanding of Jeanne’s clinical situation and helps formulate psychotherapeutic and prophylactic recommendations. We suggest that so-called “denial” is a psychological mechanism that should be reconsidered. Denial is not a mechanism pertaining to anorexic subjects alone, but is also a process encountered both in the patient’s family and in the therapeutic environment. Anorexic denial is based on anosognosia and the refusal to see one’s own thinness, while other people’s denial consists in a widespread inability to perceive the altruism and intersubjective problematic on which the existence of an anorexic subject fundamentally depends.

Let G be a simple graph of n vertices. We consider the problem ISil of deciding whether there exists an induced subtree with exactly i ≤ n vertices and l leaves in G. We also study the associated optimization problem, that consists in computing the maximal number of leaves, denoted by L_G(i), realized by an induced subtree with i vertices, for 2 ≤ i ≤ n. We compute the values of the map L_G for some classical families of graphs and in particular for the d-dimensional hypercubic graphs Q_d , d ≤ 6. Then we prove that the ISil problem is in general NP-complete. We also describe a nontrivial branch and bound algorithm that computes the function L_G for any simple graph G. In the special case where G is a tree, we provide a O(δn^3) time and O(n^2) space algorithm, where δ is the maximum degree of G. Finally, we exhibit a bijection between the set of discrete derivative of the sequences L_G (i) where G is caterpillar, and the set of prefix normal words. [less ▲]

Over the past decade, in vitro methods have been developed to study intestinal fermentation in pigs and its influence on the digestive physiology and health. In these methods, ingredients are fermented by a bacterial inoculum diluted in a mineral buffer solution. Generally, a reducing agent such as Na2S or cysteine-HCl generates the required anaerobic environment by releasing metabolites similar to those produced when protein is fermented, possibly inducing a dysbiosis. An experiment was conducted to study the impact of two reducing agents on results yielded by such in vitro fermentation models. Protein (soybean proteins, casein) and carbohydrate (potato starch, cellulose) ingredients were fermented in vitro by bacteria isolated from fresh feces obtained from three sows in three carbonate-based incubation media differing in reducing agent: (i) Na2S, (ii) cysteine-HCl and (iii) control with a mere saturation with CO2 and devoid of reducing agent. The gas production during fermentation was recorded over 72 h. Short chain fatty acids (SCFA) production after 24 and 72 h and microbial composition of the fermentation broth after 24 h were compared between ingredients and between reducing agents. The fermentation residues after 24 h were also evaluated in terms of cytotoxicity using Caco-2 cell monolayers. Results showed that the effect of the ingredient induced higher differences than the reducing agent. Among the latter, cysteine-HCl induced the strongest differences compared with the control, whereas Na2S was similar to the control for most parameters. For all ingredients, final gas produced per g of substrate was similar ( P>0.10) for the three reducing agents whereas the maximum rate of gas production ( Rmax) was reduced ( P<0.05) when carbohydrate ingredients were fermented with cysteine-HCl in comparison to Na2S and the control. For all ingredients, total SCFA production was similar ( P>0.10) after 24 h of fermentation with Na2S and in the control without reducing agent. Molar ratios of branched chain-fatty acids were higher ( P<0.05) for protein (36.5% and 9.7% for casein and soybean proteins, respectively) than for carbohydrate (<4%) ingredients. Only fermentation residues of casein showed a possible cytotoxic effect regardless of the reducing agent ( P<0.05). Concerning the microbial composition of the fermentation broth, most significant differences in phyla and in genera ascribable to the reducing agent were found with potato starch and casein. In conclusion, saturating the incubation media with CO2 seems sufficient to generate a suitable anaerobic environment for intestinal microbes and the use of a reducing agent can be omitted. [less ▲]

La confrontation de la version anonyme en vers de Barlaam et Josaphat avec sa mise en prose, produite au XIIIe siècle, offre un point de vue privilégié sur la langue littéraire en prose, à l’aube de son épanouissement. Parallèlement au retranchement d’épisodes entiers, le remanieur s’applique à conserver une étroite proximité avec la lettre de son modèle francien, et semble tendre vers un compromis entre fidélité au texte-source et intelligibilité du texte-cible. Ainsi, à côté de l’importation massive du matériau lexical et des structures syntaxiques du texte versifié, toutes ses interventions sont observables. Notre communication s’est focalisée sur un échantillon de neuf substitutions lexicales dont nous avons mesuré la fréquence et dont il s’agissait d’identifier les implications. En tant que témoins de l’actualisation linguistique du texte-source, ces variations (diachroniques et/ou diaphasiques) permettent d’améliorer la connaissance du vocabulaire de la mise en prose de Barlaam et Josaphat et de cerner avec plus de précision la sensibilité du remanieur à l’égard du lexique de sa source.

The purpose of this paper is to provide a comprehensive state of the art of fatigue and cyclic loading of natural rock materials. Papers published in the literature are classified and listed in order to ease bibliographical review, to gather data (sometimes contradictory) on classical experimental results and to analyse the main interpretation concepts. Their advantages and limitations are discussed, and perspectives for further work are highlighted. The first section summarises and defines the different experimental set-ups (type of loading, type of experiment) already applied to cyclic/fatigue investigation of rock materials. The papers are then listed based on these different definitions. Typical results are highlighted in next section. Fatigue/cyclic loading mainly results in accumulation of plastic deformation and/or damage cycle after cycle. A sample cyclically loaded at constant amplitude finally leads to failure even if the peak load is lower than its monotonic strength. This subcritical crack is due to a diffuse microfracturing and decohesion of the rock structure. The third section reviews and comments the concepts used to interpret the results. The fatigue limit and S–N curves are the most common concepts used to describe fatigue experiments. Results published from all papers are gathered into a single figure to highlight the tendency. Predicting the monotonic peak strength of a sample is found to be critical in order to compute accurate S–N curves. Finally, open questions are listed to provide a state of the art of grey areas in the understanding of fatigue mechanisms and challenges for the future. [less ▲]
