Self-consistent dynamics of non-homogeneous fluctuations and homogeneous and isotropic condensate of Yang–Mills fields was investigated in zero, linear and quasilinear approximations over the wave modes in the framework of N = 4 supersymmetric model in Hamilton gauge in quasiclassical theory. The models with SU(2), SU(3) and SU(4) gauge groups were considered. Particle production effect and effect

Using the development of intergovernmental environmental cooperation in the Baltic Sea area as a concrete example, the aim of this study is to explore how the ‘environ- ment’ in situations of environmental interdependence is identified and institutional- ised as political-geographical objects. ‘Environmental interdependence’ is to this end conceptualised as a tension between ‘political spaces’ of

A novel Stacked Multi-Level (SML) modulator topology optimized for long pulse and high average power applications has been developed at ESS. It utilizes six identical modules connected in series at the HV output side and fed in parallel from the low voltage side. Each one is formed by one HF inverter, one step-up transformer, one HV rectifier bridge and one HV passive filter. They are supplied, in

A National Synchrotron Radiation Centre SOLARIS has been recently built in Krakow, Poland. The accelera tor is in commissioning phase. The control system is in operation and provides all functionalities required for the commissioning process. The system is based on Tango Controls and has been developed with strong collabora tion with MAX-IV, Lund Sweden and the Tango Commu nity. Protections system

The notion of development blocks (Dahmén, 1950, 1991) suggests the co-evolution of technologies and industries through complementarities and the overcoming of imbalances. This study proposes and applies a methodology to analyse development blocks empirically. To assess the extent and character of innovational interdependencies between industries the study combines analysis of innovation biographie

OBJECTIVE: The objective of this nationwide study was to analyze how functional status and socioeconomic status affect return to work (RTW) among younger patients with first-time stroke in a Sweden.MATERIAL AND METHODS: This register-based cohort study included employed patients aged 25-55 with first-time stroke between 2008 and 2011 and primary outcome was RTW within 1 year after stroke. Data reg

Active synapses can reduce the probability of transmitter release at neighbouring synapses. Depending on whether such heterosynaptic depression is mediated by intersynaptic diffusion of transmitter or by release of gliotransmitters, astrocytes should either hinder or promote the heterosynaptic depression. In the present study we have examined the developmental profile and astrocytic involvement in

Samhällsekonomiska analyser är ett viktigt underlag för beslut i infrastruktur- och transportplaneringen. En av de effekter som värderas i samhällsekonomiska analyser är klimateffekter och för detta krävs att man gör en bedömning av koldioxidvärdet, det vill säga, kostnaden för koldioxidutsläpp, vilket anges i kr/kg CO2. Dock finns det olika sätt att värdera koldioxid och det finns ingen konsensus

Wood components such as cellulose, lignin and hemicelluloses all have potential to be used in biobased value-added products. Once extracted from the wood these components have to be separated and purified from co-extracted compounds. Membrane filtration can be used to achieve this separation and is believed to play an important role in biorefineries.Fouling is the single greatest obstacle to the i
