Particle-stabilized emulsions, called Pickering emulsions, can be produced by using starch particles. In this work we studied how the properties of the starch particles affect the droplet size and creaming of such emulsions. In the study, various sizes of starch particles were generated by two different methods and used to stabilize Pickering emulsions. Sedimentation according to Stokes’ law was u
Starch microspheres were produced by emulsification of a starch dispersion in an aqueous polyethylene glycol (PEG) solution. Crystalline/ordered structure was formed within these starch droplets during incubation at 6 °C for 25 h followed by incubation at 37 °C for 28 h. After incubation at 37 °C the crystalline structure in the samples was of type B. The crystallization process of microspheres wa
Fifty years have passed since the Stockholm School of economic thought was carried to the font by Bertil Ohlin. As was fitting, the anniversary was celebrated with a conference in Stockholm to which prominent economists made pilgrimage from near and far. Even before this, an extra fine commemorative gift had been proffered in Lund, the very city from which such bitter criticism had once upon a tim
In Eli F. Heckscher's conception of the world, what he called “distributary systems” (ledningssystem) played a dangerously crucial role. He used this term to denote the means of transport, communications and power transmission, that is, in substance those activities which are commonly termed natural monopolies. Until the 1920s he believed that these monopolies could be held in check by potential c
Swedish economists have received impulses from historical or institutuionalist sources on many occasions. A couple of these economists, Gunnar Myrdal and Johan Åkerman, received obvious impulses from American institutionalism. This article deals with the case of Åkerman. To attempt a wall-to-wall chart of institutional influences on an economist is hardly possible. But what is possible is to exami
The continual interaction between economic change and economic policies designed to manage or guide this change seldom finds such dramatic expression as when one type of economy replaces another, e. g., when the industrial economy replaces the agrarian or is in turn supplanted by the “post-industrial” economy.Thus, when the American economy was in the thick of its industrial revolution during the
