The aim of this paper is to investigate the flow of MHD mixed convection nanofluid flow under nonlinear heated due to an extending surface. The transfer of heat in nanofluid subject to a magnetic field and boundary conditions of convective is studied to obtain the physical meaning of the convection phenomenon. The governing partial differential equations of the boundary layer are reduced to ordinary differential equations considering a technique of the transformation of similarity. The transformed equations are solved numerically considering (...) the technique of an efficient numerical shooting applying the Runge–Kutta technique scheme from the fourth-fifth order. The results corresponding to the dimensionless speed, temperature, concentration profiles, and the Nusselt number reduced, and the Sherwood numbers are presented by figures to display the physical meaning of the phenomena. A comparison has been made between the obtained results with the previous results obtained by others and agrees with them if the new parameters vanish. The results obtained indicate the impacts of the nondimensional governing parameters, namely, magnetic field parameter M, Soret number Sr, heat source λ, thermal buoyancy parameter λ T, and solutal buoyancy parameter λ C on the flow, temperature, and concentration profiles being discussed and presented graphically.

Irregularity may occur on the earth’s surface in the form of mountains due to the imperfection of the earth’s crust. To explore the influence of horizontally polarized shear waves on mountains, we considered the fluid-saturated porous medium over an orthotropic semi-infinite medium with rigid and soft mountain surfaces for wave propagation. The mountain surface is defined mathematically as a periodic function of the time domain. The physical interpretation of materials’ structure has been explained in rectangular Cartesian coordinate system originated at (...) the contact interface of layer and half-space. The displacement of the mountains has been derived by solving energy equations analytically. The influence of rigid and soft mountain surfaces on the phase velocity of shear waves has been demonstrated graphically. (shrink)

Malek Bennabi naît en 1905 dans une Algérie occupée par la France. Aux côtés de savants algériens dont la devise est "L'islam est notre religion, l'Algérie est notre patrie, l'Arabe notre langue", il forme sa pensée, qui demeure encore trop injustement méconnue jusque dans son pays natal. Les axes centraux de l'idéologie bennabienne (religion, spiritualité, réforme, colonisabilité...) trouvent pourtant leurs échos dans la France d'aujourd'hui. Son constat situant la décadence de la civilisation islamique à la fin de la dynastie Almohade (...) (XIIIe siècle) est percutant. Il engendre un ensemble de conséquences dont les savants contemporains n'ont peut-être pas encore pris la mesure. Cet ouvrage trace les parallèles entre l'analyse visionnaire de Bennabi et les caractéristiques de l'époque actuelle. Si les modalités des maux peuvent être différenciées, l'analogie entre les événements des deux époques permet de tirer de son oeuvre des solutions actuelles et efficaces. (shrink)

Jamel Khermimoun considers that Muslims born in France and in the West now build their identity not from an imported model but from a strong sense of belonging to the nation, which they claim at the same time as their Islam. He wants to shed light on his reading of texts guided by the spirit of flexibility and openness advocated by Islam. We must listen carefully to what he has to say to us; one must know how to confront (...) ones own point of view with ones own, and thus enter into a process of dialogue which, as he writes himself, creates real issues and is capable of appeasing the spirits (Jean Baubrot, professor emeritus of the Chair History and Sociology of Secularism [Ecole Pratique des Hautes Etudes in Paris] and author of several books). Through this book, the author has the merit of advocating the creation of a field of mutual acquaintance [...], a base of common values that can help Westerners and Muslims to get out of the tunnel of reciprocal prejudices, to protect together the true notion of secularism that calls for respect for individual choices and the defense of the right of expression (Claudia Mansueto, doctor of literature, professor at the University of Trieste). Jamel Khermimoun provides answers to the questions raised by the place of the Muslim religion in modern societies. For the author, Islam is not incompatible with secularism because it shares with it the most important values which make possible cohabitation, or even mutual enrichment. Instead of opposing them, it encourages us to reinvest the republican principles that make up our societies. [...] It is for those of us who want to understand the world in which they live. The links of Islam to modernity, to knowledge, to the idea of freedom, to the equality of the sexes, to violence, to fanaticism, to racism, are here dealt with frankness and clarity (Victor Loupan, journalist, author, former international reporter at Figaro Magazine).

Diabetes is one of the most common metabolic diseases that cause high blood sugar. Early diagnosis of such a condition is challenging due to its complex interdependence on various factors. There is a need to develop critical decision support systems to assist medical practitioners in the diagnosis process. This research proposes developing a predictive model that can achieve a high classification accuracy of type 2 diabetes. The study consisted of two fundamental parts. Firstly, the study investigated handling missing data adopting (...) data imputation, namely, median value imputation, K-nearest neighbor imputation, and iterative imputation. Consequently, the study validated the implications of these imputations using various classification algorithms, i.e., linear, tree-based, and ensemble algorithms, to see how each method affected classification accuracy. Secondly, Artificial Neural Network was employed to model the best performing imputed data, balanced with SMOTETomek ensuring each class is represented fairly. This approach provided the best accuracy of 98% on the test data, outperforming accuracies achieved in prior studies using the same dataset. The dataset used in this study is concerned with gender and population. As a prospect, the study recommends adopting a larger population sample without geographic boundaries. Additionally, as the developed Artificial Neural Network model did not undergo any specific hyperparameter tuning, it would be interesting to explore tuning on top of normalized data to optimize accuracy further.

In this paper, wavelet coherences and quantile autoregressive distributed lag approaches are used to study the effect of economic policy uncertainty, infectious disease EMV tracker, and implied volatility on illiquidity during the tranquil and COVID-19 epidemic periods in the US financial market. Our results show that lagged EPU, current VIX, and lagged VIX positively affect illiquidity during the calm period, while the lagged EPU and current VIX decrease illiquidity during the pandemic period. Furthermore, infectious diseases in the financial market during (...) the pandemic crisis play a significant role in instantaneously improving liquidity, while it was not significant during the tranquil period. Similarly, we suggest that with the combined effect of the EPU and the VIX, the uncertainty caused by implied volatility decreases liquidity in a lagged and contemporaneous manner, while an improvement in liquidity is revealed in the case of the EPU.
