Cette recherche porte sur la description et l'analyse des scènes romantiques représentées et élaborées sur les carreaux de revêtement utilisés dans la décoration architecturelle durant les époques safavide et qajar en Iran. Cet essai traite les différentes techniques qui étaient en usage dans la fabrication et la décoration de ces carreaux en céramique. nCes carreaux, nommés 'Kāšānī' ou 'kāšī', consiste un répertoire iconographique et littéraire de ces deux époques, dont la production artistique est assez riche qui le fruit d'un mélange d'influences iraniennes et européennes. n La plupart des scènes romantiques, choisies et analysées dans la présente recherche, sont inspirées des oeuvres littéraires persans, des épopées de Šāhnāmeh d'al-Firdawsī et de Nizāmī, comme Khusrū et Širīn et Layla waʾl Majnūn. n Cet essai entend analyser et comparer, d'un point de vue artistique, les différents aspects du traitement de ces scènes romantiques sous les safavides et les qajars, les techniques utilisées, les styles, les postures, les cadres, les couleurs et les vêtements.

L'Iran était un des pays islamiques les plus célèbres pour la fabrication et la décoration des armes. Voulant restaurer la gloire de ses ancêtres, elle a fondé une industrie basée sur les traditions artistiques sassanides, qui ont marqué l\"époque de luxe et de grandeur de la Perse. nCette recherche traite un des armes métallurgique les plus en usage durant l\"époque Qajar, les poignards, qui jouissent d'un attrait particulier pour les guerriers, ils étaient, non seulement utilisés à des fins de défenses et de combats, mais aussi durant les cérémonies et les réceptions officielles devant les dirigeants militaires. D'autre part, les garnitures exubérantes des poignards Qajars, dorés et incrustés de pierres précieuses étaient carrément utilisés pour désigner les rangs militaires. nAu début de l\"époque qajar, les artistes désiraient revenir aux traditions artistiques classiques de l\"ère sassanide, néanmoins, bientôt touchés par les influences européennes, les oeuvres qajars ont commencé à avoir un nouveau goût. nDivers sortes de poignards ont été exécutées sous les Qajars, avec une lame droite, courbée, à seul ou à double tranchant, desservis de fourreaux en bois ou en argent, et décorés d\"un amalgame de garnitures. Cette recherche met en relief les différents représentations picturales sur les poignards Qajars, à partir de nombreux spécimens exposés dans des musées en Iran et à l\"étranger; ces représentations s\"étale sur une vaste gamme de thèmes artistiques, qui comprend des portraits de Šāhs, des femmes, et d\"autres représentations figuratives comme certains animaux, symboliquement liés à la mythologie iranienne.

Les blasons chez les musulmans, leurs formes, leur origine et leur fonction, est un sujet qui a fait couler beaucoup d'encre. Il existait diverses sortes de blasons, personnel ou fonctionnel, simples ou composés, temporels ou permanents.nCette recherche traite un blason fonctionnel d'une importance primordiale, et qui est figuré sur divers monuments et pièces d'arts appliqués, c'est le blason du calice, attribué aux échansons; une charge assez sensible dans la cour du sultan et dont le responsable devait, à l'époque, jouir d'une confiance ultime de la part du sultan pour la remplir.nParmi les divers arts appliqués, cette recherche met l'accent sur le blason du calice, exécuté sur les tapis mamelouks, sans doute, considérés comme des pièces artistiques distinctes dont les techniques de la fabrication ainsi que les couleurs lui offrent une identité unique.nLes musées d'arts à l'étranger comportent des chefs- d'œuvres des tapis fabriqués en Egypte sous les mamelouks, la présente contribution en analyse quelques pièces, comportant le blason d'échanson sous différentes formes et couleurs.

The arrival of the Fatimid conquerors to Egypt was a turning point which brought forth a radical impact on both political and religious sides of life. Coming from quite a different doctrinal background, the Fatimids had a predominating aim to spread their beliefs between the Egyptian populace. Perhaps one of their workable tactics to diffuse the shi'i doctrine was the introduction of mausoleums (mashads), devoted to the burial of their Fatimid imams- who claimed the ultimate descent from \"al- Husayn Ibn 'AIi Ibn Abi Talib\". Although Islam has strict traditions against funerary architecture, the Fatimid mashads did the trick; they were, and still are, highly venerated by the Sunni populace of Egypt. This research is an attempt to reach a better understanding of the influence of the Shiite doctrine on the function of funerary architecture in Fatimid Egypt, while shedding light on women's vital role in achieving this objective.

Nowadays, integrating corporate social responsibility (CSR) initiatives into business is an important challenge facing organizations development. Corporations that embrace this concept reap many benefits including customer loyalty, positive attitudes toward brands, customer trust, positive publicity and better financial performance. Increased spending on CSR initiatives is expected to increase customer satisfaction and build competitive advantage. In today's competitive airline business environment, companies are striking to retain their existing customers and gain the repurchase intention of customers. As a result, an increasing number of airlines have implemented CSR initiatives. CSR programs become active channels for building customer loyalty as customers appear to provide greater support for companies that are socially and environmentally responsible. Accordingly, Customer loyalty becomes one of the most essential consumers behaviors that airlines endeavor to influence through the use of corporate social responsibility as a marketing tool in their strategies. Therefore, this paper aims at exploring the relationship between corporate social responsibility and customer loyalty in the airline industry. It also tries to discover the main critical factors that have more effect on social responsibility in the airline industry. To achieve the purposes of this paper, a model was developed to measure the influence of airlines corporate social responsibility activities in customer loyalty and airline image. This model includes 16 attributes, which have been selected to cover airlines CRS activities, and 21 initial items for measuring customer loyalty. The proposed model was presented as a self administrated questionnaire. The sample chosen in this study includes mainly international airlines passengers (727 passengers). Furthermore, the analysis of simple linear regression and spearman correlation are applied. The results of this study confirm that there is a significance statistical relationship between airlines CRS activities and customer loyalty. The results also determine that social responsibility activities related to customers and community are the most important factors affecting customer perception of the airline image.

A compact dual-frequency ( 38 / 60   GHz ) microstrip patch antenna with novel design is proposed for 5G mobile handsets to combine complicated radiation mechanisms for dual-band operation. The proposed antenna is composed of two electromagnetically coupled patches. The first patch is directly fed by a microstrip line and is mainly responsible for radiation in the lower band ( 38   GHz ). The second patch is fed through both capacitive and inductive coupling to the first patch and is mainly responsible for radiation in the upper frequency band ( 60   GHz ). Numerical and experimental results show good performance regarding return loss, bandwidth, radiation patterns, radiation efficiency, and gain. The impedance matching bandwidths achieved in the 38   GHz and 60   GHz bands are about 2   GHz and 3.2   GHz , respectively. The minimum value of the return loss is − 42 dB for the 38   GHz band and − 47 for the 60   GHz band. Radiation patterns are omnidirectional with a balloon-like shape for both bands, which makes the proposed single antenna an excellent candidate for a multiple-input multiple-output (MIMO) system constructed from a number of properly allocated elements for 5G mobile communications with excellent diversity schemes. Numerical comparisons show that the proposed antenna is superior to other published designs.

After its emergence in China, the coronavirus SARS-CoV-2 has swept the world, leading to global health crises with millions of deaths. COVID-19 clinical manifestations differ in severity, ranging from mild symptoms to severe disease. Although perturbation of metabolism has been reported as a part of the host response to COVID-19 infection, scarce data exist that describe stage-specific changes in host metabolites during the infection and how this could stratify patients based on severity. Given this knowledge gap, we performed targeted metabolomics profiling and then used machine learning models and biostatistics to characterize the alteration patterns of 50 metabolites and 17 blood parameters measured in a cohort of 295 human subjects. They were categorized into healthy controls, non-severe, severe and critical groups with their outcomes. Subject's demographic and clinical data were also used in the analyses to provide more robust predictive models. The non-severe and severe COVID-19 patients experienced the strongest changes in metabolite repertoire, whereas less intense changes occur during the critical phase. Panels of 15, 14, 2 and 2 key metabolites were identified as predictors for non-severe, severe, critical and dead patients, respectively. Specifically, arginine and malonyl methylmalonyl succinylcarnitine were significant biomarkers for the onset of COVID-19 infection and tauroursodeoxycholic acid were potential biomarkers for disease progression. Measuring blood parameters enhanced the predictive power of metabolic signatures during critical illness. Metabolomic signatures are distinctive for each stage of COVID-19 infection. This has great translation potential as it opens new therapeutic and diagnostic prospective based on key metabolites.

Iron deficiency anaemia (IDA) is a major health issues and common type of nutritional deficiency worldwide. For IDA treatment, intravenous (IV) iron is a useful therapy. To determine the efficacy and cost-effectiveness (CE) of intravenous (IV) Ferric Carboxymaltose (FCM) versus IV Iron Sucrose (IS) in treating IDA. Electronic medical record i.e. Cerner.sup.® system. IV Ferric Carboxymaltose versus IV Iron Sucrose. With regard to responses to treatment i.e., efficacy of treatment with FCM & IS in IDA patients, hemoglobin (Hgb), ferritin, and transferrin saturation (TSAT) levels were the primary outcomes. Additionally, the researchers also collected levels of iron, platelet, white blood cell (WBC), red blood cell (RBC), mean corpuscular hemoglobin (MCH), and mean corpuscular volume (MCV). The costs i.e. resources consumed (obtained from NCCCR-HMC) and the CE of FCM versus IS were the secondary outcomes. There was a significant improvement in Hgb, RBC and MCH levels in the IS group than the FCM group. The overall cost of IS therapy was significantly higher than FCM. The medication cost for FCM was approximately 6.5 times higher than IS, nonetheless, it is cheaper in terms of bed cost and nursing cost. The cost effectiveness (CE) ratio illustrated that FCM and IS were significantly different in terms of Hgb, ferritin and MCH levels. Further, Incremental Cost Effectiveness Ratio (ICER) indicated that further justifications and decisions need to be made for FCM when using Hgb, iron, TSAT, MCH and MCV levels as surrogate outcomes. Not applicable. The higher cost of FCM versus IS can be offset by savings in healthcare personnel time and bed space. ICER indicated that further justifications and decisions need to be made for FCM when using Hgb, iron, TSAT, MCH and MCV levels as surrogate outcomes.

The introduction of activated carbon/natural zeolite (AC/NZ) as an efficient and reliable nanoadsorbent for enhancing methylene blue (MB) dye adsorption. By calcining sugarcane waste at various temperatures between 500 and 900 °C, activated carbons (ACs) are formed. Both XRD and SEM were used for the characterization of the prepared adsorbents. Adsorption measurements for the removal of MB dye were made on the impact of pH, beginning MB concentration, and contact time. The maximum AC500/NZ adsorption capacity for MB dye at 25 °C, pH 7, and an AC500/NZ mass of 50 mg was found to be approximately 51 mg/g at an initial concentration of 30 ppm. The pseudo-second-order kinetics model and the Temkin isotherm model describe the adsorption process. The Temkin model shows that the adsorption energy is 1.0 kcal/mol, indicating that the MB-to-AC500/NZ adsorption process occurs physically. Our Monte Carlo (MC) simulation studies supported our findings and showed that the Van der Waals dispersion force was responsible for the MB molecule's physical adsorption. The AC500/NZ adsorbent is thought to be a strong contender for water remediation.

COVID-19 is a recent pandemic that mandated the scientific society to provide effective evidence-based therapeutic approaches for the prevention and treatment for such a global threat, especially to those patients who hold a higher risk of infection and complications, such as patients with autoimmune diseases and cancer. Recent research has examined the role of various fat-soluble vitamins (vitamins A, D, E, and K) in reducing the severity of COVID-19 infection. Studies showed that deficiency in fat-soluble vitamins abrogates the immune system, thus rendering individuals more susceptible to COVID-19 infection. Moreover, another line of evidence showed that supplementation of fat-soluble vitamins during the course of infection enhances the viral clearance episode by promoting an adequate immune response. However, more thorough research is needed to define the adequate use of vitamin supplements in cancer and autoimmune patients infected with COVID-19. Moreover, it is crucial to highlight the vitamin–drug interactions of the COVID-19 therapeutic modalities and fat-soluble vitamins. With an emphasis on cancer and autoimmune patients, the current review aims to clarify the role of fat-soluble vitamins in SARS-CoV-2 infection and to estimate the risk-to-benefit ratio of a fat-soluble supplement administered to patients taking FDA-approved COVID-19 medications such as antivirals, anti-inflammatory, receptor blockers, and monoclonal antibodies.
