L’ouverture d’un espace dialogique dans les interventions intellectuelles de Jeanne Lapointe
Authors: Noël Alex 
Published: August 2019

Le débat qui a opposé Jeanne Lapointe à Mgr Félix-Antoine Savard et à Pierre Gélinas dans les pages de Cité libre en 1954 et en 1955 est considéré comme un moment phare dans l’émergence de la littérature comme discipline du savoir universitaire. Or, nous croyons qu’il permet aussi de saisir comment et contre quoi s’est érigée la figure de l’intellectuelle chez Lapointe. L’hypothèse au coeur de notre article est donc que se dessinent déjà, dans ce premier débat médiatisé par Cité libre, les contours d’une posture intellectuelle singulière que Lapointe continuera de développer par la suite. Plus précisément, nous souhaitons proposer une définition de cette posture, que nous résumons par les termes de retournement dialogique. Nous entendons par là une stratégie qui vise moins à convaincre l’adversaire qu’à retourner contre le discours monologique de celui-ci ses propres arguments, à renverser contre lui la lecture du monde qu’il impose (et les valeurs qu’elle transporte) dans le but d’ébranler l’hégémonie de son discours (et de sa pensée).
La sensibilité intégraliste sous la Révolution tranquille : l’exemple des chrétiens de gauche de la revue Maintenant (1962-1974)
Authors: Roy Martin 
Published: August 2019

Dans le contexte agité de la Révolution tranquille et du renouveau conciliaire, les chrétiens de gauche de la revue Maintenant ont conçu une forme particulière de sensibilité religieuse intégraliste. Ils confèrent, en effet, à la foi chrétienne des incidences élargies, voire totalisantes qui excèdent les seules questions privées et ultimes, mais sans l’assortir de bases institutionnelles typiques d’une chrétienté. Ainsi, partisans d’un intégralisme minimal, ils se dissocient à la fois de la variante maximale de l’intégralisme et de la conception marginaliste du religieux. De la première, ils rejettent principalement l’idéal de chrétienté ; et de la seconde, ils refusent la réduction de la foi chrétienne aux seules questions intimes et ultimes, car, selon eux, elle ne saurait être sans incidences en matière sociopolitique.
« Nous sommes l’un des deux peuples fondateurs et nous voulons être traités comme tel » : la référence canadienne-française dans la presse franco-ontarienne (1969-1982)
Authors: Miville Serge 
Published: August 2019

Cette étude de la presse franco-ontarienne entre 1969 et 1982 s’intéresse à la persistance de la référence canadienne-française dans les journaux en Ontario français. L’auteur, qui propose une analyse des principaux hebdomadaires francophones de la province et de l’édition du samedi du Droit, tente de faire ressortir les liens de continuité existant entre l’identité franco-ontarienne et l’identité canadienne-française au lendemain des États généraux du Canada français. Le projet de société en Ontario français, loin d’être « normaliste », s’est largement inspiré d’une certaine interprétation du projet canadien-français. Les journaux citent, notamment, la thèse des deux peuples fondateurs et le droit d’aînesse des Franco-Ontariens dans la province pour justifier l’attribution de nouveaux droits et de nouvelles institutions à la minorité française en Ontario.
Postural control in girls with adolescent idiopathic scoliosis while wearing a Chêneau brace or performing active self-correction: a pilot study
Authors: Piątek Elżbieta , Kuczyński Michał , Ostrowska Bożena 
Published: August 2019

BackgroundIt is known that adolescent idiopathic scoliosis (AIS) is often accompanied by balance deficits. This reciprocal relationship must be taken into account when prescribing new therapeutic modalities because these may differently affect postural control, interacting with therapy and influencing its results.ObjectiveThe purpose was to compare postural control in girls with AIS while wearing the Chêneau brace (BRA) or performing active self-correction (ASC) with their postural control in a quiet comfortable stance.MethodsNine subjects were evaluated on a force plate in three series of two 20-s quiet standing trials with eyes open or closed; three blocks were randomly arranged: normal quiet stance (QST), quiet stance with BRA, and quiet stance with ASC. On the basis of centre-of-pressure (COP) recordings, the spatial and temporal COP parameters were computed.Results and DiscussionPerforming ASC was associated with a significant backward excursion of the COP mean position with eyes open and closed (ES = 0.56 and 0.65, respectively;p < 0.05). This excursion was accompanied by an increase in the COP fractal dimension (ES = 1.05 and 0.98;p < 0.05) and frequency (ES = 0.78;p = 0.10 and ES = 1.14;p < 0.05) in the mediolateral (ML) plane. Finally, both therapeutic modalities decreased COP sample entropy with eyes closed in the anteroposterior (AP) plane. Wearing BRA resulted in ES = 1.45 (p < 0.05) while performing ASC in ES = 0.76 (p = 0.13).ConclusionThe observed changes in the fractal dimension (complexity) and frequency caused by ASC account for better adaptability of patients to environmental demands and for their adequate resources of available postural strategies in the ML plane. These changes in sway structure were accompanied by a significant (around 25 mm) backward excursion of the mean COP position. However, this improvement was achieved at the cost of lower automaticity, i.e. higher attentional involvement in postural control in the AP plane. Wearing BRA may have an undesirable effect on some aspects of body balance.

Published: August 2019

Aims: Potato (Solanum tuberosum L.) is the most important staple food in the world and plays an important role in food and nutritional security. Induced mutation generates variation within potato germplasm to widen the genetic base for breeding purposes. Polyploidy modifies both the genotype and phenotype of an organism, generating diverse changes that consequently transform the potato production. Potato has chromosomes with different ploidy levels which can be determined by counting chloroplasts in stomatal guard cells.
Study Design: The study was carried out in completely randomized block design.
Place and Duration of Study: Department of Biotechnology, University of Eldoret, between February 2015 and July 2016.
Methodology: The study involved 163 potato mutants developed from three commercially grown Kenyan potato varieties; Asante, Mpya, and Sherekea irradiated using gamma rays from 60Co source under different dose rates. Three middle leaves of greenhouse-grown plants were randomly selected for chloroplast counts in ten pairs of stomata guard cells on the lower surface of the leaf. Data on the number of chloroplast counts per mutant was calculated as a percentage of the parents or control and descriptive analysis.
Results: The results indicate that the number of ploidy level distribution was decreasing in diploids and triploids and were increasing in tetraploids from M1V1, M1V2 to M1V3 in all the potato mutant populations.
Conclusion: This shows that mutation induction generates genetic variations from which desired mutants may be selected based on the appropriate breeding strategies.

Authors: Khalooei Ali , Benrazavy Lila 
Published: August 2019

Aims: Diabetes self-management (DSM) plays a crucial role in diabetes control. The present study was conducted to evaluate DSM and its related factors among type 2 diabetes mellitus (T2DM) patients.
Methods: A cross-sectional study was carried out among T2DM patients from January to March 2017 in urban healthcare centers of Kerman city, southeast Iran. A total of 600 T2DM patients were enrolled in the study using a multistage sampling method. Valid and reliable diabetes self-management questionnaire (DSMQ) was employed for data collection.
Results: The mean (±SD) score of DSM was 6.92 (±1.17) out of 10 with inter quartile range 6.25-7.70. DSM mean score was higher in patients with higher educational level and household income significantly. Employed subjects (mean=7.18) had a higher DSM mean score than unemployed ones (mean=6.84). Moreover, DSM was better in patients who receive insulin and those with diabetes-related complications. DSM had a direct correlation with the number of visits by specialist physicians (r = 0.257, P < 0.001) and treatment duration (r = 0.103, P = 0.013). University education (Beta = 0.243, P < 0.001) was the strongest predictor of DMS, followed by high school education (Beta = 0.226, P < 0.001) and number of annual visits in primary healthcare centers (Beta = 0.205, P < 0.001).
Conclusion: Self-Management behaviors were suboptimal among the diabetes patients. There-fore, designing and implementing effective interventions to improve self-care behaviors of diabetic patients is necessary in the first level of health delivery system in Iran.
Expression patterns of kiss2 and gpr54‐2 in Monopterus albus suggest these genes may play a role in sex reversal in fish
Authors: Yi Ti‐Lin , Pei Meng‐Ting , Yang Dai‐Qin 
Published: August 2019

Due to its exceptionally small genome size and protogynous hermaphroditism, Monopterus albus has been proposed as a model for vertebrate sexual development. The Kiss/GPR54 system is a central regulator of sexual development in most vertebrates, but its role in sex reversal remains hypothetical. In contrast to mammals, fishes often possess more than one copy of the kiss and gpr54 genes. Our objectives were to identify all kiss/gpr54 genes in the genome of M. albus and to assess their involvement in sex reversal via their expression patterns (qPCR) in females, males, and intersex specimens. We identified only two genes: kiss2 and gpr54‐2. kiss2 expression was extremely high in the gonads of males, intermediate in females, and low in intersex; and reduced in all tissues of intersex. gpr54 expression was also extremely high in the gonads of males, high in intersex, but low in females. gpr54 expression in brain was high in all three sexes. In conclusion, (a) kiss1 has been functionally replaced in M. albus; (b) the functions of gpr54‐2 in brain are not sex‐specific; (c) kiss2 appears to undergo a ‘reset’ in the expression during the sex change; and (d) sex‐specific expression patterns in the gonads indicate that these two genes may play a role in sex reversal in fish.

Published: August 2019

AbstractFor cancer diagnosis, 1H magnetic resonance imaging (MRI) is advantageous in sensitivity but lacks selectivity. Endogenous 19F MRI signal in humans is barely detectable and thus 19F MRI has very high selectivity. A combination of 1H and 19F MRI is ideal for precise tumor imaging but a protease‐controlled strategy of simultaneous T2 1H MRI enhancement and 19F MRI “Turn‐On” has not been reported. Here, used is a click condensation reaction to rationally project a dual‐functional fluorine probe 4‐(trifluoromethyl)benzoic acid (TFMB)‐Arg‐Val‐Arg‐Arg‐Cys(StBu)‐Lys‐CBT (1), which is further utilized to functionalize Fe3O4 nanoparticle (IONP) to achieve IONP@1. As such, the IONP aggregation can be activated by furin addition, thereby enhancing the T2 1H MRI signal and switching the 19F NMR/MRI signal “On”. Using this strategy, IONP@1 is successfully applied to detect the activity of the furin enzyme with “Turn‐On” 19F NMR/MRI and T2 1H MRI signals are enhanced. Moreover, IONP@1 is also applied for precise dual‐mode (1H and 19F) MR imaging of tumors in zebrafish under 14.1 T. The current approach, therefore, provides a feasible and robust means to reconcile the dilemma between selectivity and sensitivity of conventional MRI probes. More importantly, it is envisioned that, by substituting the TFMB moiety in 1 with a perfluorinated compound, this “smart” method could be of potential use for precise 1H MR and 19F MR imaging of tumor in mouse or in bigger rodents in near future.

Published: August 2019

AbstractThe hybrid organic–inorganic perovskites (HOIPs) form a new class of semiconductors which show promising optoelectronic device applications. Remarkably, the optoelectronic properties of HOIP are tunable by changing the chemical components of their building blocks. Recently, the HOIP spintronic properties and their applications in spintronic devices have attracted substantial interest. Here the impact of the chemical component diversity in HOIPs on their spintronic properties is studied. Spin valve devices based on HOIPs with different organic cations and halogen atoms are fabricated. The spin diffusion length is obtained in the various HOIPs by measuring the giant magnetoresistance (GMR) response in spin valve devices with different perovskite interlayer thicknesses. In addition spin lifetime is also measured from the Hanle response. It is found that the spintronic properties of HOIPs are mainly determined by the halogen atoms, rather than the organic cations. The study provides a clear avenue for engineering spintronic devices based on HOIPs.

Published: August 2019

AbstractPtCo alloy@cobalt benzoate/graphene (PtCo@Co‐BA/Gr) composite catalyst with 0D/1D/2D multidimensional structure is presented with simple solvothermal approach. As the introduced critical carrier, benzoic acid cobalt (II) (Co‐BA) has porous channels matching the size of platinum (Pt) nanoparticles and can enable PtCo alloy particles to be formed in its 1D mesopores through in situ reduction. Experiments indicate that the hydroxyl (OH) groups on the outer surface of Co‐BA are beneficial to form a strong interaction between Co‐BA and graphene. Compared with commercial Pt/C catalyst, the prepared PtCo@Co‐BA/Gr composite catalysts display an enlarged electrochemically active surface area, enhanced catalytic activity, and prolonged durability in acidic media toward the oxidation of various alcohols, such as methanol, ethanol, and ethylene glycol, which is mainly due to the increased surface area of PtCo by the confinement of mesoporous Co‐BA fiber, the promotion of water molecule dissociation of Co‐BA skeleton, and the improvement of conductivity by the introduction of graphene.

Published: August 2019

AbstractFiber‐sensor‐based real‐time monitoring of the degree of exposure of the human body to ultraviolet (UV) rays is one of the technologies in the field of smart healthcare‐based wearable devices. With the development of wearable UV sensors, it is essential to build technologies with stable durability and excellent sensing capabilities for continuous movement and with water, sweat, and external contaminants. In this study, a fiber sensor is investigated that can stably detect UV intensity even when exposed to liquids such as water. The device consists of SnO2 nanowires, which are sensitive to UV intensity, arranged on a polyurethane (PU) fiber in a random network pattern, with the aim to minimize the amount of current change caused by various tensile and compressive stresses encountered by the wearable sensor. To prevent the distortion of the measured current that may occur in the semiconductor sensing channel as a result of external water exposure, a (1H,1H,2H,2H‐heptadecafluorodec‐1‐yl) phosphonic acid (HDF‐PA)‐coated Al2O3 nanoparticles (NPs) with a UV transmittance of 77% are coated on the networked SnO2 nanowire channel. The SnO2 nanowire‐networked PU fiber covered with the HDF‐PA coated Al2O3 NPs is confirmed to be sensitive only to UV, without reacting to external water under various bending conditions.

Published: August 2019

AbstractTernary blend approaches are demonstrated as a universal means to improve overall performance of organic photovoltaics (OPVs) in both indoor and outdoor conditions. A comparative study on two donors:one acceptor (2D:1A) and one donor:two acceptors (1D:2A) ternary blends shows that both approaches are universally effective for indoor and outdoor operation; the 1D:2A devices incorporating a nonfullerene acceptor (NFA) benefit from less charge recombination and higher power conversion efficiencies (PCEs) for various irradiation conditions, while the performance of the 2D:1A blends depends on the emission spectrum of the incident light source. The synergistic merits of NFAs and ternary structure in the 1D:2A ternary OPVs secure better performance and generality regardless of the incident lighting. A combination of experimental and theoretical analyses unveils that NFAs optimize packing and arrangement of molecules to build efficient cascade ternary junctions in the 1D:2A blends, which can be important design guidelines for the third component in ternary OPVs. The optimized 1D:2A ternary OPV exhibits a new record PCE of 25.6% under a 200 lux light‐emitting diode (LED) and 26.4% under a 1000 lux LED, and superior durability under industrial relevant thermal stress, suggesting new opportunities in diverse practical applications challenging the currently dominant PV technologies.
A simple kinetic model for complex rheological fluids based on irreversible thermodynamics

Published: August 2019

AbstractIn this work, we analyze the kinetics of the entanglement–disentanglement process of complex fluids coupled to a rheological constitutive equation of state within an irreversible thermodynamics framework. In the context of the coupling between the kinetics and the mechanical phenomena, we assume that the rate constants are functions of the affinities that contain the chemical potentials, which are themselves functions of the extended Gibbs free energy containing the irreversible dissipation terms. Although the derived model has a simple mathematical structure, it is able to predict complex flow behaviors, including shear‐thickening, shear‐thinning, and more complex flow histories such as shear‐banding. As special case, we derive the constitutive equations of the Bautista–Manero–Puig (BMP) model in which the material constants have a thermodynamic basis and have been successfully used for the last two decades to predict the behavior of complex fluids such as the ones examined here.
The effect of carrier surface roughness on wall collision‐induced detachment of micronized pharmaceutical particles
Authors: Tamadondar Mohammad R. , Rasmuson Anders 
Published: August 2019

AbstractRepeated particle‐wall collisions are regarded as a contributory mechanism to the detachment of micronized pharmaceutical particles from carrier particles in inhaler devices. A natural and not much studied feature of these carrier particles are their surface roughness. In the present study, we simulate the collision‐induced dispersion behavior of dry‐coated rough particles by means of the discrete element method. Carrier particles with controllable length scales of roughness are generated based on the concept of Fourier shape descriptors. The dispersion efficiency correlates well with the statistical measures of the surface asperities. Moreover, the collision energy is found to contribute to the degree of fine particle detachment. At the rebound, it is observed that the majority of remaining fine particles fall into the particle cavities and establish multiple contacts with the carrier surface. These results corroborate with experimental findings and emphasize the significant effect of surface asperities in the context of inhalable particles.
Advanced age adversely affects chronic rhinosinusitis surgical outcomes

Published: August 2019

BackgroundPatient‐specific and disease‐specific factors shape the course of chronic rhinosinusitis (CRS) and its response to treatment, with optimal management involving interventions tailored to these factors. Recent evidence suggests CRS inflammatory signatures depend on age. The objective of this study was to determine whether age also influences quality‐of‐life (QOL) and postoperative outcomes.MethodsRetrospective analysis of prospectively collected QOL data from 403 adults with medically refractory CRS who underwent functional endoscopic sinus surgery (FESS) at a tertiary care medical center between 2014 and 2018 was undertaken. Total and subdomain scores from the 22‐item Sino‐Nasal Outcome Test (SNOT‐22) and the Short Form 8 Health Survey (SF‐8) measure of general health completed at preoperative and postoperative visits were reviewed.ResultsPatients were divided into young (18 to 39 years, n = 100), middle‐aged (40 to 59 years, n = 172), and elderly (≥60 years, n = 131) groups. Baseline total SNOT‐22 scores differed between groups (p = 0.01), with middle‐aged patients having the highest symptom burden and elderly patients having the lowest. Similar patterns were observed for SNOT‐22 subdomains. Elderly patients reported smaller improvements and were less likely to achieve a minimally important clinical difference. CRS patients had worse SF‐8 scores compared to the general population, and elderly patients were the least likely to match population norms following surgery. Age was an independent predictor of QOL outcomes after FESS.ConclusionAge may play a significant role in CRS pathophysiology, symptom burden, and surgical outcomes. Elderly patients report smaller improvements in disease‐specific and general health QOL after surgery. CRS management in the elderly population should incorporate age‐dependent differences in symptom burden and expectations into treatment algorithms.
Renal‐clearable Molecular Semiconductor for Second Near‐Infrared Fluorescence Imaging of Kidney Dysfunction

Published: August 2019

AbstractReal‐time imaging of kidney function is important to assess the nephrotoxicity of drugs and monitor the progression of renal diseases; however, it remains challenging because of the lack of optical agents with high renal clearance and high signal‐to‐background ratio (SBR). Herein, a second near‐infrared (NIR‐II) fluorescent molecular semiconductor (CDIR2) is synthesized for real‐time imaging of kidney dysfunction in living mice. CDIR2 not only has a high renal clearance efficiency (≈90 % injection dosage at 24 h post‐injection), but also solely undergoes glomerular filtration into urine without being reabsorbed and secreted in renal tubules. Such a unidirectional renal clearance pathway of CDIR2 permits real‐time monitoring of kidney dysfunction in living mice upon nephrotoxic exposure. Thus, this study not only introduces a molecular renal probe but also provides useful molecular guidelines to increase the renal clearance efficiency of NIR‐II fluorescent agents.
