- A numerical model is developed to study the MHD mixed convective boundary layer viscoelastic fluid flow over a stretching sheet embedded in a porous medium in presence of viscous dissipation and non-uniform heat source have been investigated. The variation of porosity is assumed. The governing partial differential equations are converted into ordinary differential equations by applying suitable similarity transformations. Thenumerical solution of the problem is also obtained by the efficient Runge-Kutta-Fehlberg method with shooting technique. Here two types of different heating processes are considered namely, PST and PHF cases. The effect of various physical parameters such as Prandtl number, Eckert number, magnetic parameter, convection parameter and porous parameter which determine the temperature profiles are shown in several plots.Some important findings reported in this work reveals that the effect of viscous dissipation and non-uniform heat source have significant impact in controlling the rate of heat transfer in the boundary layer region.

No man’s brand : brands, institutions, fashion and the economy
- 2006

Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Branding has become so intertwined with consumption that today’s consumers have often deeply personal relationships to brands and brand histories. Branding is an attempt to strategically ‘personify’ products and to encapsulate a balance between different economic values: quality, utility, symbolic and cultural worth. In this paper we argue that the relationship between the contemporary consumer and producer is mediated by and governed by a reflexive construction of brands. As such brands are best understood from an institutional perspective. The paper illustrates the institutional role of brand by using the example of the fashion industry. It is argued that in the fashion industry a focus on consumer-producer brandbuilding and brand loyalty now takes pole-position in determining industrial and innovation dynamics. We conclude by suggesting that economic geography has consistently undervalued brands as an area of study. By taking brands as the core product in industrial production, rather than as an interesting aside for sociologists, historians and cultural theorists, economic geography can better understand the institutions governing the economy. In particular better understanding the institution of brand helps us better appreciate the dynamics systems within which commodities and commodity chains are formed.
