This paper analyzes post-socialist industrial development and policy in the Western Balkans through lens of its regional specialization spatial concentration. Against a conceptual framework revolving around place-based policy, using Concentration index (modified Herfindahl-Hirschman index) location coefficients (Balassa index), comparative analysis over three decades (1990–2020) highlights weak...

Simulating grain (Ng) and straw (Ns) nitrogen (N) concentration is of paramount importance in cropping systems simulation models. In this paper we present a simple model to partition N between grain and straw at harvest for barley (Hordeum vulgare L.), wheat (Triticum aestivum L.), maize (Zea mays L.), and sorghum (Sorghum bicolor Moench). The principle of the model is to partition the abovegro...
