The Rosenzweig-MacArthur (1963) criterion is a graphical criterion that has been widely used for elucidating the local stability properties of the Gause (1934) type predator-prey systems. It has not been stated whether a similar criterion holds for models with explicit resource dynamics (Kooi et al. (1998)), like the chemostat model. In this paper we use the implicit function theorem and implic...

Purpose Research based on Bangladesh–US trade data examines the Heckscher–Ohlin model and Rybczynski hypothesis in this study. Design/methodology/approach Ordinary least square (OLS) techniques are used study, which relies from NBER International Trade Geography Data UN Comtrade Database for years 2018 2008. Findings The research shows that between United States Bangladesh follows Rybcyzinski's...

The study of differential equations is useful in to analyze the possible past or future with help of present information. In this paper, the behavior of solutions has been analyzed around the equilibrium points for Gause model. Finally, some results are worked out to exist the stable periodic orbit for mentioned predator-prey system.

Rethinking the foundations of Heckscher–Ohlin theory when countries have different technologies, this paper shows how to make the proper adjustments for international productivity differences. The central tool is a factor conversion matrix that computes the local factor content of foreign Rybczynski effects. Factor-specific productivities are a special case of these more general linear relation...

the architectural education along the way of creativity has often involved with the formal and physical aspects of design as an effort to read architectural artifacts through its mere external appearances. this article, however, aims to step beyond the manifestation of conventional perspectives on visual aspects of built environment. that is, an act of interpreting the architectural spaces thro...
