The Construction of the Self in the Memoirs of Exile : Anzia Yezierska and Lucette Lagnado
No full textBased upon a vision of exile as a traumatic experience, this thesis offers an in-depth analysis of the memoirs of the Jewish Egyptian author Lucette Lagnado and the Jewish Polish writer Anzia Yezierska. Theories of psychological trauma are used in order to demonstrate how these memoirists’ experiences have been embodied in historical and contemporary discourse. In the first chapter we study the reasons behind the exilic experience of each writer. Relying on exile theory conceptualized by Sophia McClellan, this first chapter deals with the spatial, temporal, and linguistic crises caused by the trauma of exile. The second chapter focuses on ethnic identity construction and how women writers conceptualize ethnic identity through their writings. The last chapter deals with the healing methods that the memoirists used in order to overcome the trauma of exile, be it on the personal or communal levelÀ partir d'une vision de l'exil comme expérience traumatisante, cette thèse propose une analyse approfondie des mémoires de l'auteure juive égyptienne, Lucette Lagnado et de l’écrivaine juive polonaise, Anzia Yezierska. Les théories du trauma sont utilisées afin de démontrer comment les expériences de ces mémorialistes sont inscrites dans un contexte discursif propre à chacune de ces auteures. Dans le premier chapitre, nous étudions les raisons de l’exil de chaque écrivaine. S’appuyant sur la théorie de l'exil conceptualisée par Sophia McClellan, ce premier chapitre traite des crises spatiales, temporelles et linguistiques engendrées par le traumatisme de l’exil. Le deuxième chapitre est axé sur la construction de l’identité ethnique et sur la façon dont les femmes écrivaines conceptualisent l’identité ethnique à travers leurs écrits. Le dernier chapitre examine les méthodes de guérison que les mémorialistes ont utilisées pour surmonter le traumatisme de l'exil, que ce soit au niveau personnel ou communautair

Synthesis, molecular modeling, quantum chemical calculations and <i>in silico</i> drug profiling of the novel (4-phenylpiperazin-1-ium) hydrogenfumarate as a tyrosinase inhibitor
No full textInternational audienceThe complexation between fumaric acid (FA) and 1-phenylpiperazine (1 PP) is a fruitful cooperation that allowed the preparation of a new organic crystal entitled (4-phenylpiperazin-1-ium) hydrogenfumarate denoted by 4PPHFUM, which is reported in the present manuscript. This new substance is created by the slow evaporation that occurs when 1-phenylpiperazine and fumaric acid are combined in a stoichiometric 1:1 ratio. The stacking of the crystal is provided by O–H⋯O, N–H⋯O and C–H⋯O hydrogen bonds, also supported by C–H⋯π interactions between the organic cations. The importance of these interactions in the formation of this new crystal is confirmed by the Hirshfeld surface analysis which showed that H-bonds and supramolecular C–H⋯π interactions account for about half of the non-covalent interactions existing in this compound. These non-covalent bonds that encompass the synthesis and design of this supramolecule have also been analyzed in detail using a quantum chemical computational study. Using the docking – based drug design strategy, we investigated the therapeutic effect of this cooperative outcome between fumaric acid and 1-phenylpiperazine to demonstrate the improved therapeutic property of this novel non-covalent compound as a tyrosinase inhibitor. 4PPHFUM was found to be a potent tyrosinase inhibitor with high interaction energy with its protein, higher than that of the most potent tyrosinase inhibitors (thiamidol, hydroquinone, resorcinol, hexylresorcinol and kojic acid)
Effects of Acute Long- versus Short-Interval High-Intensity Interval Training on Attention and Psychological States in a Sample of Male and Female Adolescents: A Pilot Study
No full textThe aim of this study was to assess the effect of acute short- versus long-interval high-intensity interval training (HIIT) on cognitive performance and psychological states in secondary school students. Fifteen secondary school students (nine males and six females: mean age = 16.2 ± 0.4 years, mean Body Mass Index = 21.2 ± 1.5 kg/m2, and maximum oxygen uptake = 42.2 ± 5.9 mL/kg/min) participated in the current study. They performed one of the following three sessions in a randomized order: (i) a long-interval HIIT (LIHIIT), (ii) a short-interval HIIT (SIHIIT), and (iii) a control condition (CC). Cognitive performance and perceived exertion were assessed pre and immediately post each condition using the d2 test and the Rating of Perceived Exertion (RPE) tool, respectively. Mood state was quantified using the Brunel Mood Scale (BRUMS) questionnaire immediately post each condition. The findings reported higher concentration performance in the SIHIIT compared to the LIHIIT condition (p = 0.043) and the CC (p < 0.001) and in the LIHIIT compared to the CC (p = 0.023). Moreover, the total count of errors was higher in the CC than in the LIHIIT (p = 0.01) and in the SIHIIT conditions (p < 0.001) and in the LIHIIT than in the SIHIIT condition (p = 0.03). RPE value was higher in the LIHIIT and SIHIIT conditions than in the CC (both p < 0.001), whereas no statistically significant difference between LIHIIT and SIHIIT conditions (p = 0.24) was found. Regarding the BRUMS, a significant difference between conditions in the fatigue subscale was found, being higher in LIHIIT with respect to SIHIIT (p = 0.03) and CC (p < 0.05). Vigor differed between conditions, with a higher value than in the LIHIIT (p = 0.04) and CC (p < 0.001). All the remaining subscales did not significantly differ between conditions (p > 0.05). Practitioners may implement short-interval HIIT prior to any tasks that require high levels of visual attention

Synthesis, Empirical and Theoretical Investigations on New Histaminium Bis(Trioxonitrate) Compound
No full textIn this paper, a novel hybrid material, entitled histaminium bis(trioxonitrate), with the general chemical formula (C5H11N3)(NO3)2, denoted by HTN was presented. Single-crystal X-ray diffraction was used to determine the structural characteristics of this compound after it was made using a slow evaporation method at room temperature. This compound was elaborated and crystallized to the monoclinic system with space group P21/c, and the lattice parameters obtained were: a = 10.4807 (16)Å, b = 11.8747 (15)Å, c = 16.194 (2)Å, β = 95.095 (6)°, V = 2007.4 (5)Å3 and Z = 8. The title compound’s atomic structure couldbe modeled as a three-dimensional network. Organic cations and nitrate anions were connected via N–H...O and C–H...O hydrogen bonds in the HTN structure. The intermolecular interactions responsible for the formation of crystal packing were evaluated using Hirshfeld surfaces and two-dimensional fingerprint plots. The compound’s infrared spectrum, which ranged from 4000 to 400 cm−1, confirmed the presence of the principal bands attributed to the internal modes of the organic cation and nitrate anions. Additionally, spectrofluorimetry and the ultraviolet–visible spectrum was used to investigate this compound. DFT calculations were used to evaluate the composition and properties of HTN. The energy gap, chemical reactivity and crystal stability of HTN were quantified by performing HOMO-LUMO frontier orbitals analysis. Topological analysis (AIM), Reduced Density Gradient (RDG), molecular electrostatic potential surface (MEPS) and Mulliken population were processed to determine the types of non-covalent interactions, atomic charges and molecular polarity in detail
Design by Radical Indigenism: Equitable Underwater & Intertidal Technologies of the Global South
No full textThis article considers the traditional water systems of indigenous cultures and explores their innovations as unique responses to the impacts of climate change in the global south. Local communities have been living with and developing water-responsive infrastructures for generations that engage and support the complex ecosystems they inhabit. Many of these innovations improve coastal resiliency, yet remain undocumented and unexplored in the evolution of contemporary solutions. Rooted in traditional ecological knowledge, or TEK, these technologies work symbiotically with, rather than against nature, and offer examples of a more comprehensive approach to underwater and intertidal design. These innovations are Lo—TEK, a term coined by designer and author Julia Watson, that is defined as resilient infrastructures developed by indigenous people through Traditional Ecological Knowledge (TEK) (Watson 2019). The movement to bring these innovations to the forefront of the design field counters the idea that Lo—TEK indigenous innovation is low-tech, a term often incorrectly applied to indigenous innovation that means unsophisticated, uncomplicated, and primitive. In actuality, Lo—TEK aligns to today’s sustainable values of low-energy, low-impact and low-cost, while producing complex nature-based innovations that are inherently sustainable. Lo-TEK expands the definition of contemporary technology by rebuilding our understanding of climate resilient design using indigenous knowledge and practices that are sustainable, adaptable, and borne out of necessity. Indigenous people have learned to live symbiotically with their environments, especially water. This essay will explore the Kuttanad Kayalnilam Farming System by the Malayalis in India, the Sangjiyutang Mulberry Dyke and Fish Ponds in China, and the Ramli Lagoon farms in Ghar El Melh, Tunisia. These innovations are inherently resilient to the stresses of the climate and are multi-functional, symbiotic structures themselves. While not directly intended for protection from the new challenge of sea level rise, they can inform how we can build circular water systems that work with the environment, rather than disrupting it
Effect of Ramadan fasting: Association with time of day on time-motion, technical aspect and psychophysiological response to simulated karate competition in young amateur competitors
No full textInternational audienceRamadan is characterized by daily abstinence from food and fluid intake from dawn to sunset. The understanding of the Ramadan effects on the diurnal variations of athletic performance is crucial for practitioners, coach and researchers to prepare sport events and optimize performance. The aim of the present study was to reveal the effect of Ramadan on the performance aspect, heart rate and rating of perceived exertion during a karate match. In a randomized counterbalanced, 2 x 2 cross-over order, 22 male and female amateur karate athletes (age = 16.8 years, body mass = 59.1 kg, height = 168.3 cm) participated in simulated karate match at 8-10 a.m. and 5-7 p.m. on three different occasions 1 week before Ramadan, the second week of Ramadan (during Ramadan), and 2 weeks after Ramadan. Performance aspects were analyzed, and heart rate and rating of perceived exertion were assessed before and immediately after the match at each visit. Our results demonstrated that Ramadan adversely affected time-motion variables (fighting time and preparatory time) and heart rate during simulated karate match (p < 0.05, all). However, heart rate pic response to karate match was higher during Ramadan when compared with before Ramadan and after Ramadan. However, rating of perceived exertion results did not show any variation during Ramadan phases. Concerning the interaction of Ramadan and time of day, fighting time and stoppage time were higher in the evening and in the morning before Ramadan and the inverse during Ramadan, respectively (p < 0.05). In conclusion, Ramadan altered the diurnal variation of performance aspect, in terms of fighting time and stoppage time, during simulated karate match

The title compound’s asymmetric unit and three-dimensional network have been determined by single crystal X-ray diffraction. Intermolecular O-H…O, N-H…O and C-H…O hydrogen bonding assist in maintaining and stabilization of the crystal structure of this new compound. Hirshfeld surface analysis and two-dimensional fingerprints have been performed to quantify the non-covalent interactions in the PPOXH structure. The vibrational modes of the different characteristic groups of the title chemical were identified using infrared spectrum analysis. The thermal characterization of this product was studied by a coupled TG/DTA analysis. The ultraviolet-visible absorption spectrum has been used to study the optical properties and the energy gap of this compound. DFT calculations were employed to evaluate the composition and properties of PPOXH. The analysis of HOMO-LUMO frontier orbitals analysis allows us to understand the chemical reactivity of this supramolecular compound and to determine the electrophilic and nucleophilic sites responsible for electron transfer. Topological analysis (AIM), reduced density gradient (RDG), molecular electrostatic potential surface (MEPS) and Mulliken population were analyzed to evaluate the types of non-covalent interactions, localization of electrons in space, atomic charges and molecular polarity in depth
