investigation into total phenolics and their spectrum in the buds and corms of saffron crocus and a study of polyphenol oxidase changes in the apical bud during different stages of growth and development showed that changes in the growth and development of the apical bud may be related to changes in the composition of phenolics in the corm. a sudden intense change in content and kind of phenoli...

We evaluate the economic consequences of endogenous immigration in a two-country, two-skill, endogenous-growth model, where human and physical capital are productive assets. Adding to model yields new insights about induced-immigration effects exogenous pull push triggers, on evolution “immigration surplus” short versus long run, destination source countries, global economy. The policy we analy...

purpose: to report a case of endogenous klebsiella endophthalmitis associated with liver abscess in iran. case report: a 79 year old man was referred with chief complaint of left eye pain and visual loss. the patient had conjunctival hyperemia, corneal edema, hypopyon and severe vitreous cellular reaction in the left eye and yellowish conjunctival discoloration which was apparent in the right e...

In this paper, we study the equilibrium dynamics of an endogenous growth model with endogenous fertility choice. We show that the model may have a unique equilibrium which is globally determinate. Mathematics Subject Classification: 49Q99, 91B62

FDI has received surprisingly little attention in theoretical and empirical work on openness and growth. This paper presents a theoretical growth model where MNCs directly affect the endogenous growth rate via technological spillovers. This is novel since other endogenous growth models with MNCs, e.g. the Grossman-Helpman model, assume away the knowledge-spillovers aspect of FDI. We also presen...

This paper analyzes the equilibrium dynamics of an AK-type endogenous growth model with vintage capital. The inclusion of vintage capital leads to oscillatory dynamics governed by replacement echoes, which additionally influence the intercept of the balanced growth path. These features, which are in sharp contrast to those from the standard AK model, can contribute to explaining the short-run d...

We derive an R&D-based semi-endogenous growth model where technological progress depends on the available amount of technological opportunity. Incremental innovations provide direct increases in the knowledge stock but they reduce technological opportunity and thus the potential for further improvements. Technological opportunity can be renewed only by radical innovations (which have no direct ...
