Abstract
As a high school senior, there was no doubt I wanted to attend college, it was just a matter of where. I applied to only two universities – Oakland University (OU) and MSU. I was not too familiar with MSU, but it had a good reputation; I was much more familiar with Oakland. Although I had obtained an application for the University of Michigan (UM), I decided that the UM application was just too long to complete. And what the heck is a wolverine anyway? I lived in Michigan for most of my life, and I had never spotted this mythical rodent. As a tendency, I always found Michigan students and alumni to be either too arrogant or eccentric for my taste. Also, at that time of my life, I found the atmosphere in Ann Arbor not right in some way, so I applied to only two universities.1

Abstract
Explores the importance of several regimes of new product development activities using multiple statistical techniques on two different data sets collected in the USA and Canada over 12 years apart. The results were consistent across the statistical methods and across the data sets, but contradict much previous new product research. In particular, it was found that undertaking technical activities proficiently is more important than performing marketing activities proficiently and that performing development stage (including subsequent) activities proficiently is more critical than performing “up‐front” or predevelopment activities proficiently in determining the success or failure of new industrial products.

Abstract
Purpose
The purpose of this paper is to study entropy generation in magneto-Jeffrey nanomaterial flow by impermeable moving boundary. Adopted nanomaterial model accounts Brownian and thermophoretic diffusions. Modeling is arranged for thermal radiation, nonlinear convection and viscous dissipation. In addition, the concept of Arrhenius activation energy associated with chemical reaction are introduced for description of mass transportation.
Design/methodology/approach
Homotopy algorithms are used to compute the system of ordinary differential equations.
Findings
The afore-stated analysis clearly notes that simultaneous aspects of activation energy and entropy generation are not yet investigated. Therefore, the intention here is to consider such effects to formulate and investigate the magneto-Jeffrey nanoliquid flow by impermeable moving surface.
Originality/value
As per the authors’ knowledge, no such work has yet been published in the literature.

Abstract
Purpose
The present work explores the influence of Hall and Ohmic heating effects on the convective peristaltic flow of a conducting Jeffrey nanofluid in an inclined porous asymmetric channel with slip. Also, the authors investigated the impact of viscous dissipation, thermal radiation, heat generation/absorption and cross diffusion effects on the flow. Peristaltic flow has many industrial and physiological applications and most of the biofluids show the non-Newtonian fluid behaviour. Further, in a living body, several biofluids flow through different kinds of systems that are not symmetric, horizontal or vertical. The purpose of this paper is to address these issues.
Design/methodology/approach
The authors considered the flow of Jeffrey fluid which is generated by a sinusoidal wave propagating on the walls of an inclined asymmetric channel. The flow model is developed from the fixed frame to the wave frame. Finally, yield the nonlinear governing equations by applying the non-dimensional quantities with the assumptions of lengthy wave and negligible Reynolds number. The exact solution has been computed for the velocity and pressure gradient. The solutions for temperature and concentration are obtained by the regular perturbation technique.
Findings
Graphical analysis is made for the present results for different values of emerging parameters and explained clearly. It is noticed that the magnetic field enriches the temperature where it drops the fluid velocity. This work describes that the temperature field is decreasing due to the radiation but it is a rising function of temperature slip parameter. The temperature profile declines for growing values of the Hall parameter. The flow velocity diminishes for boosting values of the Darcy parameter. Further, the authors perceived that the concentration field reduces for large values of the chemical reaction parameter.
Originality/value
The authors validated and compared the results with the existing literature. This investigation will help to study some physiological systems, and heat transfer in peristaltic transport plays key role in medical treatments, so we ensure that these results are applicable in medical treatments like cancer therapy, drug delivery, etc.

Abstract
Purpose
The purpose of this paper is to predict the effects of magnetic field, heat and mass transfer and rotation on the peristaltic flow of an incompressible Newtonian fluid in a channel with compliant walls. The whole system is in a rotating frame of reference.
Design/methodology/approach
The governing equations of two-dimensional fluid have been simplified under long wavelength and low Reynolds number approximation. The solutions are carried out for the stream function, temperature, concentration field, velocity and heat transfer coefficient.
Findings
The results indicate that the effects of permeability, magnetic field and rotation are very pronounced in the phenomena. Impacts of various involved parameters appearing in the solutions are carefully analyzed.
Originality/value
The effect of the concentration distribution, heat and mass transfer and rotation on the wave frame is analyzed theoretically and computed numerically. Numerical results are given and illustrated graphically in each case considered. A comparison was made with the results obtained in the presence and absence of rotation, magnetic field and heat and mass transfer.
