Abstract In the present study, ion-acoustic solitary wave solutions for Kadomtsev–Petviashvili (KP) equation, potential KP and Gardner equation are constructed. The nonlinear equations studying process of waves without collisions plasma having non-isothermal electrons cold ions. Two-dimensional (IASWs) in magnetized consisting We obtained same as dark bright, kink anti-kink solitons. physical p...

We study the problem of gravity surface waves for an ideal fluid model in (2+1)-dimensional case. apply a systematic procedure to derive Boussinesq equations given relation between orders four expansion parameters, amplitude parameter $\alpha$, long-wavelength $\beta$, transverse wavelength $\gamma$, and bottom variation $\delta$. derived only possible extensions Korteweg-de Vries equation, fif...

HE tumorous head (tu-h) abnormality and genetic mechanism were disTcussed by GARDNER (1948), GARDNER and WOOLF (1949) and NEWBY ( 1949). Penetrance, expressivity and relative viability were investigated by GARDNER and RATTY (1952). The influence of high and low temperatures on the expression was described by GARDNER and WOOLF (1950). Modifiers and alleles of tumorous head genes were found in la...

In this letter, we established a traveling wave solution by using cosine function algorithm for Gardnerequation and (2+1)-dimensional breaking soliton system. The cosine method is used to obtain theexact solution.

Gardner-Diamond syndrome, which also is knownas autoerythrocyte sensitization disorder, is a raresyndrome of inflammatory, edematous papulesthat evolve into painful ecchymoses on the trunkand lower legs after a period of stress with no priorhistory of trauma. This syndrome usually occurs inwomen with a history of psychiatric disorders, themost common one being depression. Although theexact mech...

Dear Mr. York: As reader services correspondent at Fellowship headquarters, I would like to thank you for sending us your review article of Martin Gardner's Urantia. Of the half-dozen reviews we've read, yours is certainly the most serious, insightful and heartening. It was also gratifying to learn that you met your first Urantia Book believers during your visit to our information center at the...

T he cell has a number of quality control mechanisms to ensure defective proteins get trashed. Most defects are detected and dealt with at the point of production to ensure that only quality proteins are released for use. But proteins can also become defective once they're at the job site. They can even be made to look bad by cowork-ers that want them destroyed, as Gard-ner discovered when stud...
