Enclosure

2022
Abstract Enclosure has long been linked to industrialization as part of a series of material and technical changes in farming which increased supply, enabling industrial development. This chapter argues that we need to move beyond a consideration of supply-and-demand and to see enclosure as a more-than-material process. Through enclosure,

Effect of two isothermal obstacles on the natural convection of nanofluid in the presence of magnetic field inside an enclosure with sinusoidal wall temperature distribution

International Journal of Heat and Mass Transfer, 2018
In this study, the effect of magnetic field on the natural convection of Al2O3-water nanofluid inside a square enclosure with isothermal obstacles and sinusoidal wall temperature distribution has been numerically studied.

Two-phase modeling of the free convection of nanofluid inside the inclined porous semi-annulus enclosure

, 2019
In the present paper, the modeling of the free convection of two-phase nanofluid inside the inclined porous semi-annulus enclosure is considered. The cavity is filled with Fe3O4-water magnetic nanofluid.

On Optimal Enclosure and Optimal Timing of Enclosure*

Economic Record, 1994
This paper demonstrates that the enforcement of property rights by enclosing properties under common access is, in general, socially suboptimal: the timing of enclosure may be inappropriate, causing inefficiency. It is argued that the first fundamental theorem of welfare economics applies for a given collection of production sets, while enclosure ...
