No full textL’intérêt porté aux travaux de recherche du Dr. El Mostafa Chadli s’est focalisé surdeux travaux importants, dont l’auteur de l’article a assuré la traduction en langue arabe :• Le premier ouvrage concerne Le Structuralisme dans les sciences du langage qui retrace la genèse et l’histoire du mouvement structuraliste et met en relief l’influence qu’il a exercé sur l’ensemble des sciences humaines et sociales ;• Le second ouvrage porte sur Le Conte merveilleux marocain. Sémiotique du texteethnographique, où le conte est considéré comme un texte ethnographique et soumis au déploiement de l’analyse sémiotique, enrichie par les apports de la linguistique de l’énonciation, la sémantique interprétative et la pragmatique
Modeling equilibrium and non-equilibrium thermophysical properties of liquid lubricants using semi-empirical approaches and neural network
No full textThis study explored the capability of semi-empirical and neural network approaches for correlating and predicting some equilibrium and non-equilibrium thermophysical properties of liquid lubricants. The equilibrium properties, including the densities and several thermodynamic coefficients for 12 liquid lubricants, were correlated and predicted through a perturbed hard-chain equation of state (PHC EoS) by an attractive term of Yukawa tail. The molecular parameters of PHC EoS were obtained by correlating them with 935 data points for the densities and isothermal compressibilities of studied systems in the 278-353 K range and pressure up to 70 MPa with the average absolute relative deviations (AARDs) of 0.36 % and 5.25 %, respectively. Then, that EoS was employed to predict the densities of other literature sources (with an AARD of 0.81 %) along with several thermodynamic coefficients, including isobaric expansivities (with an AARD of 12.92 %), thermal pressure coefficients (with the AARD of 12.93 %), and internal pressure (with the AARD of 13.67 %), for which the reference values were obtained from Tait-type equations and available in literature. Apart from the equilibrium mentioned above properties, the PHC EoS was combined with a rough hard-sphere-chain (RHSC) model to correlate and predict the 548 data points for the viscosities of 7 selected liquefied lubricants in 283-353 K range and pressures up to 100 MPa with the AARD of 11.85 %. The accuracy of the results from the RHSC-based model has also been compared with an empirical P eta T equation of Tammann-Tait type and an artificial neural network (ANN), both of which were developed in this work. The ANN of one hidden layer and 13 neurons was trained using the back-propagation algorithm. The results acquired from this approach were very promising and demonstrated the potential of the ANN approach for predicting the viscosity of lubricants, reaching an AARD of 0.81 % for the entire dataset

Shape Control Method For Nanoparticles For Making Better And New Catalysts
No full textA method for shape controlled synthesis of colloidal metal nanoparticles includes providing a solution of 8x10-5 M K₂ PtCl₄ and water in a reaction vessel and maintaining the vessel at a constant temperature of approximately 25°C. 0.1 M sodium polyacrylate is then added to the solution. Thereafter, argon gas is bubbled through the solution for approximately 20 minutes, and then hydrogen gas is bubbled through the solution for approximately 5 minutes to saturate the solution and so that platinum ions in the solution are reduced. The reaction vessel is sealed and the solution is allowed to stand for approximately 12 hours, whereby platinum colloidal nanoparticles possessing a particular shape distribution and size distribution are formed. The shape and size distributions of produced nanoparticles can be manipulated by changing the ratio of the concentration of sodium polyacrylate to platinum ions in a subsequently formed solution while maintaining all other variables constant.Georgia Tech Reseach Corporatio
Developing Sustainable Streets in Egypt in Relation to Public Needs Case Study; Mostafa El-Nahas Axis
No full textOne of Egypt\u27s most worked-on agendas is developing a new enhanced streets network, which directly impacts street users, city residents, and most certainly the economics of the country as a whole. Additionally, street design has an immense impact on developing livable and sustainable cities, since designing them sufficiently means that one-third of the city design is successful, with a tremendous effect on the remainder of the city, especially on already established cities and their residents. The crucial factor is to apply a comprehensive approach in planning or developing them, where all factors involved must be considered, including pedestrians, vehicles, parking slots, etc. This must be achieved without neglecting the important role of public participation in matters of concern. Thus, this study aimed at analyzing one of the newly developed streets in Nasr City, Cairo, to assess its achievement and if it needs enhancement from the public point of view. It was found that the latest development of the Mostafa El-Nahas Axis was favored by the majority of the study sample. However, some enhancements must be conducted on the detail level. For example, the study sample expressed the need for increasing plantations on the street and making it more pedestrian friendly

Spectroscopic Diagnostics For Bacteria In Biologic Sample
No full textA method to analyze and diagnose specific bacteria in a biologic sample using spectroscopy is disclosed. The method includes obtaining the spectra of a biologic sample of a non-infected patient for use as a reference, subtracting the reference from the spectra of an infected sample, and comparing the fingerprint regions of the resulting differential spectrum with reference spectra of bacteria in saline. Using this diagnostic technique, specific bacteria can be identified sooner and without culturing, bacteria-specific antibiotics can be prescribed sooner, resulting in decreased likelihood of antibiotic resistance and an overall reduction of medical costs.Georgia Tech Research Corp.Boston Medical Center Corp
