André Gide & Edmond Jaloux
Authors: Gide André , Jaloux Edmond 
Published: August 2022

Le jeudi 23 avril 1896, dans sa chambre de la rue des Tonneliers à Marseille, un jeune poète de 18 ans, qui vient de faire paraître à compte d’auteur un recueil de vers symbolistes, reçoit la visite inattendue d’André Gide, de huit ans son aîné. Entre Edmond Jaloux et l’auteur de Paludes et du Voyage d’Urien dont il lit les œuvres à la manière d’un bréviaire où pulser un sens à sa vie et à son engagement littéraire, c’est le début d’une longue amitié qui, sans être ni pour l’un ni pour l’autre de premier plan, durera avec ses cimes et ses creux jusqu’à la fin de leurs jours. La correspondance, inaugurée par cette première rencontre, constitue d’abord pour le plus jeune une véritable initiation morale et intellectuelle, jalonnée par ses lectures renouvelées des œuvres de l’aîné – le « Récit de Ménalque », Les Nourritures terrestres et L’Immoraliste qu’il est l’un des premiers à comprendre - puis par l’écriture de ses premiers textes en prose qu’il soumet tremblant à son maître, enfin par l’attente fiévreuse de ses visites qu’il souhaiterait toujours plus fréquentes.Cette amitié passionnée de l’apprenti poète pour l’écrivain déjà reconnu par une élite pourrait sembler disproportionnée, mais Gide, qui ressent une vive sympathie pour l’enthousiasme de ce néophyte, éprouve auprès de lui la force de l’influence en littérature en l’aidant à se découvrir romancier. Ces lettres, inédites pour l’essentiel, découvrent ainsi les débuts d’une aventure intellectuelle et montrent que l’éducation d’un esprit ne consiste pas à le faire pareil à soi, mais à développer sa profonde singularité, son « idiosyncrasie » aurait dit Gide. Elles redonnent aussi vie à Edmond Jaloux, que son œuvre abondante, injustement oubliée, porta à l’Académie et dont le magistère, exercé notamment aux Nouvelles littéraires, fit de lui le critique le plus redouté de son temps.
André Gide & Eugène Rouart 1

Published: August 2022

On ne peut tout à fait comprendre l’œuvre et la vie d’André Gide sans y marquer la place essentielle tenue par son amitié avec Eugène Rouart. De 1893 à 1936, les liens entre les deux hommes, souvent tendus, parfois distants, restèrent affectueux, malgré les événements et les idées qui ont pu les troubler. Leur Correspondance, une des plus importantes et des plus révélatrices parmi celles que Gide entretint avec les plus notables de ses contemporains, aborde des domaines très divers : la littérature, bien sûr, mais également les beaux-arts, la sexualité, la politique, l’industrie et le commerce, les affaires, l’agriculture...Élevé dans un milieu de peintres, de musiciens, d’hommes politiques, d’industriels, Rouart offrait à Gide de nombreuses ouvertures dans le monde culturel de son époque. L’homosexualité rapprocha les deux amis. C’est dans ses lettres à Rouart que Gide conçut le projet d’écrire Corydon. Dédicataire de Paludes, Rouart écrivit un roman, La Villa sans maître, qui inspira L’Immoraliste où les chapitres sur l’activité agricole en particulier portent l’empreinte de cet homme dont Gide dira que sa vie était « la plus compliquée, la plus foisonnante et la plus dramatique » qu’il ait pu voir.Antidreyfusard fougueux en 1898, Rouart devint quelques années plus tard un pilier de la IIIe République - maire, conseiller général, chef de cabinet d’un ministre important, enfin sénateur. Captivé par le caractère hors norme de son ami, Gide se laissa entraîner par lui dans diverses entreprises commerciales que la publication de ces lettres éclaire pour la première fois. Elles fournissent aussi des précisions inédites sur la crise que le ménage Gide traversa en 1916-1918 et d’où naquit La Symphonie pastorale. L’intensité avec laquelle Rouart poursuivait ses ambitions, écartelé entre sa vie publique et ses désirs intimes, trouvait en Gide, constamment à l’affût d’expériences psychologiques hors du commun, un observateur attentif, toujours prompt à mettre à profit les aventures d’autrui : c’est ainsi que Rouart, au sommet de sa carrière, membre de l’Académie d’Agriculture et sénateur de la Haute-Garonne, sera le modèle du Robert de L’École des femmes.

Authors: Naguib Rehab M. , El-Rifaie Abd-El A. , El-Taweel Abd-El A. , Dahab Mohamed M.F.A.A. 
Published: August 2022

Background
Psoriasis is a chronic hyperproliferative inflammatory disease, in which genetic and environmental factors have an important role, but the exact cause is yet unknown. Circular RNAs (circRNAs) are regulatory noncoding RNAs. They play an important role in multiple physiological and pathological processes, such as cancer, cardiovascular diseases, and neuronal diseases. Some circRNAs are involved in regulating immunity, inflammation, and cell proliferation in many types of cells.

Aim
To detect the expression of circRNA (Circ0061012) in psoriatic skin of diseased patients as compared with normal control persons to investigate the possible role of circRNA in psoriasis pathogenesis and its correlation with disease severity.

Patients and methods
The present study included 30 psoriatic patients and 30 healthy controls. A 4-mm punch skin biopsy was taken from patients (psoriatic lesion) and controls, and it was kept in the lysis solution for the stability of the studied parameters and was kept frozen at -80°Celsius till analysis of circRNA by real-time polymerase chain reaction.

Results
The tissue level of circRNA (Circ0061012) was significantly higher among patients with psoriasis as compared with normal control individuals.

Conclusion
circRNA could contribute to psoriasis pathogenesis through its immunomodulatory role, so it might be a therapeutic target in the future.
Assessment of tissue expression of matrix metalloproteinase-9 level in patients with vitiligo and its relation to disease pattern, activity, and severity

Published: August 2022

Background
Vitiligo is a common acquired depigmentary disorder characterized by milky-white cutaneous macules devoid of identifiable functional melanocytes of unknown origin. Several hypotheses have been advanced to explain the link between matrix metalloproteinase-9 (MMP-9) and vitiligo.

Aim
We aimed to compare the tissue expression of MMP-9 in vitiligo lesions with that of healthy controls.

Patients and methods
A case–control study was performed to evaluate MMP-9 levels by punch biopsies using an immunohistochemistry technique in lesional and nonlesional tissues of the same patient with vitiligo and in comparison with healthy controls. The study included 20 patients (10 patients with vitiligo and 10 healthy controls). Patients included were 18 years of age and older of both sexes, any duration, and any subtype.

Results
MMP-9 expression was found to be lower in the lesional skin of patients with vitiligo at the basal cell layer, follicular epithelium, and stromal cell layer when compared with nonlesional skin of the same patient with vitiligo and matched control individuals.

Conclusion
Tissue MMP-9 imbalance has a role in the etiopathogenesis of vitiligo. The low MMP-9 tissue expression may not facilitate the migration of melanoblasts. Tissue MMP-9 is a significant predictor of severity of vitiligo.

Authors: Tawfik Noha Z. , Mahmoud Ghada H. , Omar Hanan H. , Gomaa Amal H.A. 
Published: August 2022

Background
Plantar warts are a common viral infection affecting adults and children. Many studies concerning bleomycin show discrepancies in cure rates. Macrophage migration inhibitory factor (MIF) plays an important role in the skin regarding inflammation and immune response. However, little is known about its relation to cutaneous warts.

Aim
To assess serum MIF levels in patients with common warts before and after treatment by microneedling-assisted topical bleomycin (MATB).

Patients and methods
This quasi experimental study included 33 patients with cutaneous warts treated by MATB. MIF levels were assessed before and after treatment.

Results
The mean serum MIF level was significantly lower before bleomycin treatment and increased after treatment.

Conclusion
The serum MIF has a role in the immunity against human papillomavirus infection and MATB is a promising noninvasive therapeutic modality for cutaneous warts.

ABSTRACT. In this study, treatment of lead containing wastewater using sewage sludge ash obtained from the incineration unit in the domestic wastewater treatment plant in Gaziantep province in Turkey was investigated. The main purpose of the study is to determine the potential of using the treatment sludge ash, which comes out as waste in the treatment plant, in the treatment of wastewater of another industry. As a result of this study, the most suitable adsorption conditions were determined and focused on the kinetics of adsorption. In the experiments, the lead adsorption capacity of sewage sludge ash was determined as 122 mg g-1 at 0.5 g L-1 adsorbent concentration in wastewater containing 100 mg L-1 Pb2+ under optimum conditions. As a result of the research, it was determined that the adsorption reaction proceeds according to the pseudo second degree reaction and is suitable for the Langmuir isotherm. As thermodynamic constants, ΔH° = 7.407 kJ mol-1 and ΔS° = 33.25 J mol-1 were determined. As a result of this, it was determined that the adsorption reaction was endothermic, spontaneous and random, and adsorption was physical adsorption. The results show that sewage sludge ash can be used in the treatment of water containing high concentrations of Pb2+.

ABSTRACT. Linear, nonlinear optical properties, photon buildup factors, and neutron shielding capability of glasses with chemical composition (65-x)B2O3-10Sb2O3-25Li2O-xBi2O3, where x = 0 (BSLB0) – 20 (BSLB20) mol% with steps of 4 mol% were examined. Molar refractivity (Rmolar) and molar polarizability (αmolar) were increased as Bi2O3 content mol% increase in the examined BSLB-glasses. The values of metallization criterion (Mcriterion) confirmed that the BSLB-glasses were non-metallic materials. The static (εstatic) and optical (εoptical) dielectric constants having the same trend of the refractive index (noptical). Values of optical electronegativity (χ*) were reduced from 0.825 for BSLB0 (Bi2O3 = 0 mol%) glasses to 0.758 for BSLB20 (Bi2O3 = 20 mol%) glasses. The linear electric/dielectric susceptibility (χ(1)) increased from 0.370 to 0.397. The nonlinear optical susceptibility (χ3) and nonlinear refractive index n2optical were enhanced by increasing Bi2O3 content in the BSLB-glasses. The BSLB20 glasses presented the least exposure and energy absorption build-up factors (EBF and EABF) at all considered thickness. BSLB20 sample achieved the best fast neutron removal cross section ( ) shield among all glasses. The total stopping powers (TSP) follows the trend (TSP)BSLB0 < (TSP)BSLB4 < (TSP)BSLB8 < (TSP)BSLB12 < (TSP)BSLB16 < (TSP)BSLB20. The electron absorbing and hence shielding capacity of the BSLB-glasses improves as their Bi2O3 content increase.

ABSTRACT. This study was aimed to determine the total phenolics contents and antioxidant capacity of white and brown teff grain samples. The free total polyphenolic content (TPPC), bound TPPC and total flavonoids content ranged from 62.1–129.9, 84.6–189.6 mg GAE/100 g and 84.4–195.1 mg QE/100 g, respectively, in white teff samples, and, 118.6–196.7, 141.1–195.1 mg GAE/100 g and 97.8–202.5 mg QE/100 g, respectively, in brown teff samples. Besides, the free 2,2-diphenyl-1-picrylhydrazyl (DPPH) and bound DPPH ranged from 74.8–98.3, 77.1–99.9 mg AAE/100 g, respectively, for white teff samples, and, 68.7–93.1 and 71.2–99.4 mg AAE/100 g, respectively, for brown teff samples. This study revealed that total phenolics content was higher in brown teff samples than white teff samples and is in agreement with other reports. However, their DPPH scavenging activities were nearly equal, indicating that both varieties of teff are relevant for human nutrition and health. Furthermore, the dendrogram has shown sharp separation of the samples based on their origin and variety related to the total phenolics parameters. Hence, findings of this study can help consumers appreciate the nutritional value of white and brown teff grains; provide them guidance for teff purchase and production.

An efficient ionic liquid-based cloud point extraction to preconcentrate mercury in environmental samples and hair of occupational workers before spectrophotometric detection
Authors: M. Garoub Mohannad , A. Gouda Ayman 
Published: August 2022

ABSTRACT. Mercury preconcentration in environmental samples and hair of occupational workers prior to spectrophotometric detection was described using a unique, eco-friendly, and quick ionic liquid-based cloud point extraction method. The discovered method used an ionic liquid 1-butyl-3-methylimidazolium hexafluorophosphate with Triton X-114 as an extracting phase in the presence of a new chelating agent 3-(2-hydroxy-5-ethoxycarbonylphen-1-ylazo)-1,2,4-triazole at pH 7.0 to separate mercury and measure the complex spectrophotometrically at wavelength 550 nm. The effects of several analytical factors on extraction performance were investigated. With a correlation coefficient of 0.9997. The calibration graph was linear in the range of 2.0-400 µg/L. The limit of detection and preconcentration factor, respectively, were 0.5 µg/L and 100. The relative standard deviation of 100 and 300 µg/L mercury (n = 10) was 1.5 and 2.2, respectively, indicating the precision and reliability of the new IL-CPE approach. The accuracy of the proposed approach confirmed through the certified reference materials analysis. The applicability of the established technique was demonstrated successfully by the estimation of trace mercury in environmental samples and hair of occupational workers.

Authors: H. Al-Hazmi Ghaferah , G. El-Desouky Mohamed , A. El-Bindary Ashraf 
Published: August 2022

ABSTRACT. At various calcination temperatures 450, 550 and 650 °C, zinc oxide nanoparticles were produced. Calcinated ZnO has high surface area as the BET was 119.12 m2g–1 and the average particle radius was calculated to be 1.16 nm. The dimension of crystallites and straining in ZnO nanoparticles' diffraction peaks remained measured. The Williamson–Hall (W–H) technique besides the size–strain approach stayed used. For each of XRD reflection peaks, physical characteristics like strain and stress were computed. Towards regulate the magnitude of crystallites, the Williamson–Hall (W–H) approach besides the size–strain technique are used that is good agreement with the size that determine from SEM as it was 22.6, 26.6 and 32.6 nm for ZnO calcinated at 450, 550 and 650 oC, individually. Using the W–H plot to modify the subversion shape, assuming an unvarying distortion model (UDM), unvarying stress deformation model (USDM), unvarying deformation energy density model (UDEDM), and The size–strain plan (SSP) approach was used to determine this. The SEM and Scherrer methods match well with the crystal size of ZnO NPs determined using W–H plots and the SSP technique.

De multiples foyers maraîchers sont dominés par l’emploi des fertilisants organiques de source animale pour relever le niveau de fertilité des sols. L’objectif de cette étude était de comparer l’effet de deux types de composts sur la performance agroéconomique de l’amarante (Amaranthus cruentus L) dans les jardins familiaux au sud du Bénin. Un dispositif en split plot à deux facteurs et quatre répétitions a été utilisé. Le premier facteur était le type de compost à deux variantes (compost à base de fiente de volaille et compost à base de bouse de vache) et le second facteur était la dose (0 ; 20 ; 30 et 40 t.ha-1). Les effets de ces deux facteurs ont été évalués par rapport au nombre de feuilles, la hauteur, le diamètre au collet, le rendement à la première et deuxième coupe ainsi que la biomasse totale de l’amarante. Sous la dose de 30t.ha-1, la fiente de volaille compostée a amélioré significativement (p < 0,001) le rendement de l’amarante (30,8 t.ha-1) avec un gain élevé et un indice d’acceptabilité ≥ 2 comparativement à la bouse de vache compostée (19,2 t.ha-1).Une dose de 30 t.ha-1de fiente de volaille compostée pourrait être recommandée aux maraîchers pour une meilleure productivité de l’amarante au Bénin.
Many market gardens are dominated by the use of organic fertilizers from animal sources in order to raise the level of soil fertility. The objective of this study was to compare the effect of two types of compost on the agronomic and economic performance of amaranth (Amaranthus cruentus L) in home gardens in southern Benin. A two-factor split plot device with four repetitions was used. The first factor was the type of two-variant compost (compost made from poultry manure and compost from cow dung) and the second factor was the dose (0; 20; 30 and 40t.ha-1). The effects of these two factors were tested on the number of leaves, the height, the diameter at the neck, the yield at the first and second cut as well as the total biomass in dry matter of amaranth. Under the dose of 30t.ha-1, composted poultry manure significantly improved the yield of amaranth (30.8 t.ha-1) with a high gain and an index of acceptability ≥ 2 compared to composted cow dung (19.2 t.ha-1). A dose of 30t.ha-1 of composted poultry manure could be recommended to market gardeners for better productivity of amaranth in Benin.

This paper is dedicated to the implementation of a law of mechanical behavior in the finite element software Cast3M using an open source code generator named Mfront. To do so, an elastoplastic behaviour model has been chosen from existing laws in the literature. Following an implicit discretization, a hardware library corresponding to the isotropic and kinematic strain-hardening model is generated using Mfront. The UMAT computer interface is used to build the library in Cast3M. A validation of the approach has been carried out by comparing the numerical results obtained with the generated hardware library and the equivalent pre-existing library in Cast3M. Simulations in the case of a tensile bar and a perforated plate show almost identical results
Ce papier est dédié à l’implantation d’une loi de comportement mécanique dans le logiciel éléments finis Cast3M à l’aide d’un générateur de code open source nommé Mfront. Pour ce faire, un modèle de comportement élasto-plastique a été choisi à partir des lois existantes dans la littérature. Suivant une discrétisation implicite, une bibliothèque matérielle correspondant au modèle de CHABOCHE à écrouissage isotrope et cinématique non linéaire est générée grâce à Mfront. L’interface informatique UMAT est utilisée pour construire la bibliothèque dans Cast3M. Une validation de l’approche a été menée en comparant les résultats numériques obtenus entre la bibliothèque matérielle générée et la bibliothèque équivalente préexistante dans Cast3M. Les simulations dans le cas d’une barre en traction et une plaque trouée montrent des résultats quasi identiques
