Münch, Morphology, Microfluidics – Our Structural Problem With The Phloem [Review Article], Michael Knoblauch, Winfried S. Peters

Winfried S. Peters

The sieve tubes of the phloem are enigmatic structures. Their role as channels for the distribution of assimilates was established in the 19th century, but their sensitivity to disturbations has hampered the elucidation of their transport mechanisms and its regulation ever since. Ernst Münch's classical monograph of 1930 is generally regarded as the first coherent theory of phloem transport, but the ‘Münchian’ pressure flow mechanism had been discussed already before the turn of the century. Münch's impact rather rested on his simple physical models of the phloem that visualized pressure flow in an intuitive way, and we argue that the …

Knowledge, Capabilities And Manufacturing Innovation: A Us-Europe Comparison, Stephen Roper, Jan Youtie, Philip Shapira, Andrea Fernandez-Ribas Mar 2010

Knowledge, Capabilities And Manufacturing Innovation: A Us-Europe Comparison, Stephen Roper, Jan Youtie, Philip Shapira, Andrea Fernandez-Ribas

This paper presents a comparative analysis of factors contributing to the innovation performance of manufacturing firms in Georgia (USA), Wales (UK), the West Midlands (UK), and Catalonia (Spain). Enabled by comparable survey data, multivariate probit models are developed to estimate how various types of firms’ innovative activities are influenced by links to external knowledge sources, internal resources, absorptive capacity, and public innovation support. The results suggest the potential for mutual learning. For the European study regions there are insights about how universities in Georgia support innovation. For Georgia and Catalonia there are lessons from UK firms about better capturing potential …
