Abstract:  This scientific report investigates the heat transfer analysis in mixed convection flow of Maxwell fluid over an oscillating vertical plate with constant wall temperature. The problem is modelled in terms of coupled partial differential equations with initial and boundary conditions. Some suitable non-dimensional variables are introduced in order to transform the governing problem into dimensionless form. The resulting problem is solved via Laplace transform method and exact solutions for velocity, shear stress and temperature are obtained. These solutions are greatly influenced with the variation of embedded parameters which include the Prandtl number and Grashof number for various times. In the absence of free convection, the corresponding solutions representing the mechanical part of velocity reduced to the well known solutions in the literature. The total velocity is presented as a sum of both cosine and sine velocities. The unsteady velocity in each case is arranged in the form of transient and post transient parts. It is found that the post transient parts are independent of time. The solutions corresponding to Newtonian fluids are recovered as a special case and comparison between Newtonian fluid and Maxwell fluid is shown graphically.

 Copy pasted from a comment at https: retractionwatch.com 2021 02 01 journal-pulls-two-studies-that-listed-an-author-without-his-permission #comments (posted on 1 February 2021):  For example, in 2017, I contacted the deputy editor of the journal Scientific Reports. I pointed out to him the following (quoted below) regarding http: dx.doi.org 10.1038 srep40147 : u201cFirst, I noted that it has 3 authors Ilyas Khan, Nehad Ali Shah L. C. C. Dennis. Second, I noted that the author contributions state that u201cI.K. formulated the problem N.A.S. solved the problem and prepared the figures. I.K. and N.A.S. wrote the main manuscript text. Both authors reviewed the manuscript.u201d Specifically, no contributions from L.C.C.D. are stated. Third, the appendix (supplementary information) lists only 2 authors: Ilyas Khan, Nehad Ali Shah. This appears to be a clearcut case of guest authorship in which, I presume, L.C.C.D. was added at a later stage after the paper was accepted. This is unethical. It breaches the guarantees made by the authors to Springer Nature in the author agreement. It is against COPE guidelines.u201d After getting the run-around for a bit, they issued an erratum (you can see it at the link above to the paper). (.....), at the bottom of the paper (link to section: https: www.nature.com articles srep40147#Sec13 ) where it tells the reader u201chow to citeu201d, it still doesnu2019t list the third (guest) author. This is right now still the case. ,
