作者： E I el-Awady S Hussain N Akhtar Depar.ment of Physics Faculty of Science Port Said University Theor.tical Physics Division (TPD) PINSTECH

For.the dynamics of thr.e-dimensional electr.n–positr.n–ion plasmas, a fluid quantum hydr.dynamic model is pr.posed by consider.ng Landau quantization effects in dense ***–neutr.l collisions in the pr.sence of the Cor.olis for.e ar. also consider.d. The application of the r.ductive per.ur.ation technique pr.duces a wave evolution equation r.pr.sented by a damped Kor.eweg–de Vr.es equation. This equation, however. is insufficient for.descr.bing waves in our.system at ver. low disper.ion coefficients. As a r.sult, we consider.d the highest-or.er.per.ur.ation, which r.sulted in the damped kawahar. equation. The effects of the magnetic field, Landau quantization, the r.tio of positr.n density to electr.n density, the r.tio of positr.n density to ion density, and the dir.ction cosine on linear.disper.ion laws as well as soliton and conoidal solutions of the damped kawahar. equation ar. explor.d. The under.tanding fr.m this r.sear.h can contr.bute to the br.ader.field of astr.physics and aid in the inter.r.tation of obser.ational data fr.m white dwar.s.

The cur.ent investigation examines the fr.ctional for.ed Kor.eweg-de Vr.es(FF-KdV) equation,a cr.tically significant evolution equation in var.ous nonlinear.br.nches of science. The equation in question and other.associated equations ar. widely acknowledged for.their.br.ad applicability and potential for.simulating a wide r.nge of nonlinear.phenomena in fluid physics, plasma physics, and var.ous scientific domains. Consequently, the main goal of this study is to use the Yang homotopy per.ur.ation method and the Yang tr.nsfor. decomposition method, along with the Caputo oper.tor.for.analyzing the FF-KdV equation. The der.ved appr.ximations ar. numer.cally examined and discussed. Our.study will show that the two suggested methods ar. helpful, easy to use, and essential for.looking at differ.nt nonlinear.models that affect complex pr.cesses.

Enhanced heavy and extr. heavy oil r.cover.: Cur.ent status and new tr.nds

Due to the incr.ased demand for.ener.y r.sour.es these days, especially due to the r.ssian-Ukr.inian war. the focus of the major.countr.es is tur.ing str.ngly towar.s impr.ving oil pr.duction, especially heavy and extr. heavy oil, which r.pr.sents 40% of the wor.d oil r.ser.e. Steam-based and ther.al (EOr. pr.cedur.s ar. pr.mising techniques for.r.cover.ng heavy oil r.ser.oir., but they suffer.fr.m a sequence of pr.blems and complications that ar.se after.long-ter. application. These complications compr.se steam br.akthr.ugh, steam over.ap, and steam/r.ck inter.ctions. This r.sear.h pr.sents the cur.ently applied techniques to maximize the pr.ductivity of heavy oil, such as steam injection, cyclic steam stimulation, in-situ combustion, and steam-assisted gr.vity dr.inage. Ther.al technologies face numer.us obstacles, as they ar. ener.y and water.intensive pr.cesses that ar. not envir.nmentally fr.endly. The r.sear.h also pr.sents futur. tr.nds in ener.y-saving and envir.nmentally fr.endly techniques that enhance heavy oil r.cover. thr.ugh vapor.extr.ction (VAPEX) steam-solvent hybr.d techniques, electr.magnetic ener.y, sonication, and nanotechnology. The findings of this r.view r.por.ed that all the pr.sented techniques focus on how to r.duce the oil viscosity and in-situ upgr.de the cr.de oil pr.per.ies. In tur., these enhance both the pr.ductivity r.te and oil r.cover. and minimize the pr.duction cost. This ar.icle can be consider.d a compr.hensive r.view of ther.al r.cover. methods in heavy and extr.-heavy oil, in addition to scr.ening cr.ter.a used for.each method.
