We employ a non-parametrical approach to growth accounting (Data Envelopment Analysis, DEA) to disentangle the proximate sources of labour productivity growth in 41 nations between 1929 and 1950 by decomposing productivity growth into four components: technological change; efficiency catch-up (movements towards the production frontier), capital accumulation and human capital accumulation. We show

Popular Abstract in English Popular science Microbial cells are small and difficult to handle in industrial processes, especially if they are to be reused subsequent batches. In order to make them easier to handle, these cells can be attached to a solid support, by so-called immobilization. This provides particles of sizes that are easy to filter and reuse. However, immobilization is associated wiAbstract Due to the finite nature of fossil resources and their environmental impact, such as greenhouse gases and climate change, the bio-based production of chemicals, materials and fuels is the subject of extensive research in industrial biotechnology. Biotransformation and fermentation are considered to be mild, “green” processes that make use of effective and reliable biocatalysts to provide

The Forward Wall Detector (FWD) is designed to identify projectile-like fragments from heavy-ion reactions at the CELSIUS storage ring in Uppsala, Sweden. FWD covers the polar angle from 3.9° to 11.7° with geometrical efficiency of 81%. The single-detection module can be either of phoswich type (10 mm fast plastic+80 mm CsI(Tl)) or ΔE−E telescope (750 μm Si+80 mm CsI(Tl)). It is expected to have c

The paper treats encounters between Swedes and Germans within the framework of lodges and secret societies in Swedish-Pomerania during the 1760-ies.

This paper addresses the control problem of a specially designed nonlinear actuator intended for use in legged robots and other related mechatronic devices. Use of this drive could considerably increase energy efficiency and the time of autonomous robot operation. Nevertheless, the highly nonlinear model of the actuator and the unavailability of part of the state for measurement pose considerable

This work presents the design, fabrication and mechanical characterisation of an integrated optical read-out scheme for cantilever-based biosensors. A cantilever can be used as a biosensor by monitoring its bending caused by the surface stress generated due to chemical reactions occurring on its surface. Here, we present a novel integrated optical read-out scheme based on single-mode waveguides th

In this paper, a new distributed space-frequency coding (DSFC) scheme, for broadband fading relay channels is presented. This scheme exhibits a spatial and a multipath diversity in a distributed fashion. An upper-bound on the pairwise error probability (PEP) is derived. From this PEP bound, it is shown that the proposed coding scheme achieves a diversity of order NL , where N is the number of rela
