To what extent have public policies contributed to the innovation performance of Finland and Sweden in the period 1970-2013? This paper aims to assess the share of innovations stimulated by the public sector, specifically because of receiving public funding or being the result of research collaboration with public institutions. We combine survey and LBIO results on these variables, to overcome rep

Integration of non-dispatchable renewable energy sources such as wind and solar into the grid is challenging due to the stochastic nature of energy sources. Hence, electrical hubs (EH) and virtual power plants that combine non-dispatchable energy sources, energy storage and dispatchable energy sources such as internal combustion generators and micro gas turbines are getting popular. However, desig

BACKGROUND: Enzymatic hydrolysis of lignocellulose is associated with mixing issues, which are likely to affect process performance. The aim of this study was to investigate how viscosity and sugar inhibition influence the mixing-dependence in hydrolysis of steam-pretreated spruce. RESULTS: The effect of agitation on low-viscosity, low-solid hydrolysis (5% water insoluble solid (WIS)) was marginal

A novel electron deficient 4,6-bis(trifluoromethyl)-1,3-phenylene diphosphinite ligand 4 was developed and synthesized. Reaction of Ir precursors with ligand 4 gave chloro(hydride) pincer complex 5, which demonstrated a higher TON in alkane dehydrogenation reactions compared to similar phosphinite based pre-catalysts. The formation of cyclooctene (COE) and tert-butylethylene adducts of the 14e cat

The focus of this paper is on investigating the influence of skewing on the torque production of an Interior Permanent Magnet Synchronous Machine (IPMSM). The machine is designed as a traction machine according to the requirements of a parallel hybrid electric commercial heavy vehicle. In order to meet the requirements, the machine is designed with a speed higher than that of the conventional powe

The topic of this paper is the role of benchmarking in Chinese e-government. Through content analysis of documentary material, this paper addresses the following questions: Which benchmarking schemes have been applied to e-government in China? What are the intentions behind the different benchmarking schemes? and Whose interests are served? Whereas previous research finds that benchmarking address

Combining straightforward molecular imprinting with orthogonal click chemistry and accessible fluorescent dyes, a modular approach has been developed to assemble turn-on optical sensors based on fluorescence resonance energy transfer in molecularly imprinted nanoparticles.

Purpose - The purpose of this paper is to investigate the numerical fluid-structure interaction (FSI) framework for the simulations of mechanical behavior of new vortex generators (VGs) in smooth wavy fin-and-elliptical tube (SWFET) heat exchanger using the ANSYS MFX Multi-field® solver. Design/methodology/approach - A three-dimensional FSI approach is proposed in this paper to provide better unde

This concluding chapter gives an overview of social inclusiveness at universities in the 11 countries covered in this book. Which are the most important obstacles for young people to do higher education studies, why do such obstacles remain, and what, if anything, is being done about it? One interesting aspect of the country studies is the difference when it comes to the role of private universiti

We extend the Tasche (2007) model on the asset correlation bias caused by a currency mismatch between assets and liabilities to the more realistic situation where just some assets and liabilities are denominated in a foreign currency. To test the significance of the remaining bias we rely on a unique database constructed by the Inter-American Development Bank (IADB) containing time-series of the a

Experiments employing extreme ultraviolet sources based on high harmonic generation often suffer from photon flux limitations. We discuss current status and prospects for scaling such sources to higher repetition rate, pulse energy and average power.

The paper presents the data on an Eemian-Late Glacial sedimentary sequence from the Zwierzyniec site, central Poland. A number of boreholes document one or two organic layers that occur beneath one or two horizons of clayey and silty deposits of ice-dammed lakes. This study demonstrates to which extent the Zwierzyniec site can contribute to a better understanding of the palaeoenvironmental changes

Aerosol particles are everywhere in the air around us, regardless of whether you are in a busy city or in the serene Arctic. Airborne particles can be produced naturally or anthropogenically, and their properties changes during the time they spend in the atmosphere. Their sizes range from about 1 nm to 100 μm, and affect us in two ways; firstly, our health by deposition in the respiratory tract, a
