The theory for the non-isothermal rheology of polymer fluids proposed in Curtiss and Bird (Adv Polym Sci 125:1–101, 1996) used several approximations including so-called linear gradient temperature field Brownian forces. While it had significant advantage dealing with equations, involved may have led to non-physical predictions. This work is a continuation (1996) that obtains corresponding non-...

sulfur mustard (sm, bis- (2-chloroethyl) sulphide) is a chemical warfare agent that causes dna alkylation, protein modification and membrane damage. sm can trigger several molecular pathways involved in inflammation and oxidative stress, which cause cell necrosis and apoptosis, and loss of cells integrity and function. epigenetic regulation of gene expression is a growing research topic and is ...

We consider a dilute suspension of dumbbells joined by finitely extendible nonlinear elastic connector evolving under the classical Warner potential , . The solvent consideration is modelled compressible Navier–Stokes system defined on torus with d = 2, 3 coupled Fokker–Planck equation (Kolmogorov forward equation) for probability density function dumbbell configuration. prove existence unique ...

We investigate finite amplitude stability of spatially inhomogeneous steady state an incompressible viscoelastic fluid which occupies a mechanically isolated vessel with walls kept at non-uniform temperature. For wide class models including the Oldroyd-B model, Giesekus FENE-P Johnson–Segalman and Phan–Thien–Tanner model we prove that is stable subject to any perturbation.

Bu araştırmada, ortaokul öğrencilerine uygulanan STEM (Science, Technology, Engineering, Mathematic) etkinliklerinin, öğrencilerin alanına yönelik tutumlarına ve fene motivasyonlarına etkisi incelenmiştir. Araştırma deneme öncesi deneysel desenlerden tek grup ön-son test modelinde yürütülmüş örneklemi Ankara ilindeki bir özel ortaokulda eğitim alan 70 öğrenciden oluşturmaktadır. Öğrencilerden e...

In this article we examine four objections to the genetic modification of human beings: the freedom argument, the giftedness argument, the authenticity argument, and the uniqueness argument. We then demonstrate that each of these arguments against genetic modification assumes a strong version of genetic determinism. Since these strong deterministic assumptions are false, the arguments against g...
