Molecular characterisation of native and processed waxy maize starch in relation to the recrystallisation behaviour of model systems and starch microspheres
Volvo for life? : An Investigation into Identity Work at Volvo Cars Torslanda
Our paper aims at making two contributions surrounding the broad discussion of subjectivity in Labour Process Theory (LPT). The first contribution is the proposition of a theoretical model to facilitate the understanding of the processes underpinning the construction of shop floor workers´ self-identities based on discursive managerial regulation. Additionally, the findings of the study are used t
Intending Engineering Work : A Conceptualisation of Engineers´ Understanding of Innovation through the Encounter with their Own Practice
Innovation is arguably one of the present-day buzzwords pervading economic, social as well as cultural life. The innovation concept however is highly ambiguous. Nevertheless most (positivistic) innovation studies employ seemingly “clear-cut” notions of innovation circumventing its highly elusive nature. These “clear-cut” innovation concepts are built on pre-conceived ontological assumptions. Inter
Funding Matters: A Study of Internationalization Programs in Science, Technology and Innovation
Research funding is essential for promoting internationalization of science, technology and innovation. It is a key mechanism to advance international science, technology and innovation (STI) cooperation. This thesis argues that funding is a dominant driver of internationalization of science, technology and innovation but it is viewed as less than an optimal mechanism because of the trade-offs and
The large influence of climate model bias on terrestrial carbon cycle simulations
Global vegetation models and terrestrial carbon cycle models are widely used for projecting the carbon balance of terrestrial ecosystems. Ensembles of such models show a large spread in carbon balance predictions, ranging from a large uptake to a release of carbon by the terrestrial biosphere, constituting a large uncertainty in the associated feedback to atmospheric CO 2 concentrations under glob

On Modeling of Thermo-Viscoplasticity of Case-Hardening Steels Over a Wide Temperature Range
The aim of this work is the development of a thermodynamically consistent fully coupled thermo-viscoplastic material model for metals.The model is based on a split ofthe free energy into a thermo-elastic, a thermo-plastic and a purely thermal part and covers nonlinear cold-work hardening and thermal softening. Nonlinear temperature dependent effects are accounted for the elastic moduli, the plasti
Status of insertion device measurement systems at MAX IV Laboratory
An insertion device lab was setup at MAX IV Laboratory and the production of insertion devices, mainly outof-vacuum is ongoing and aided by new magnetic measurement systems. A new 5.5 m long Hall probe bench is used for field map measurements and a new hybrid flip coil and stretch wire system will be used for field integrals of full devices as well as individual magnet blocks characterisation. Thi
MAX IV 3 GeV storage ring magnet block production series measurement results
The MAX IV 3 GeV storage ring magnets are integrated "magnet block" units consisting of several consecutive magnet elements precision-machined out of a common solid iron block. In the 3 GeV ring, there are 140 magnet blocks containing a total of 1320 magnet elements. During the manufacturing phase of the project, a field measurement was performed for each magnet element, by Hall probe and/or by ro
ESS progressing into construction
The construction of the European Spallation Source, ESS, started in summer 2014. At the site in Lund, the accelerator tunnel will be completed at the time of IPAC16, while prototyping and manufacturing or preparations for manpower contributions are going on in more 23 laboratories distributed over the 12 European countries collaborating on the accelerator project. Major technical milestones have b
Fast tracking of nonlinear dynamics in the ESS linac simulator via particle-count invariance
Real-time beam modeling has been used in accelerator diagnostics for several decades. Along the way, the theory for matrix calculations of linear forces has matured, allowing for fast calculations of a beam's momentum and position distributions. This formalism becomes complicated and ultimately breaks down with high-order beam elements like sextupoles. Such elements can be accurately modeled with

Commissioning of the harmonic cavities in the MAX IV 3 GeV ring
The MAX IV 3 GeV storage ring operates with beam of high current and ultralow emittance. These beam parameters in combination with the small effective aperture enhance possible collective beam instabilities. Three passive harmonic cavities are installed to introduce bunch lengthening and tune spread, leading to decoupling of the bunch spectrum from the machine effective impedance and mitigating in
Status of the Front Ends project at MAXIV
The MAX IV laboratory is a Swedish national laboratory for synchrotron radiation hosted by the Lund University. It will operate two storage rings to produce synchrotron light of very high intensity and quality over a broad wavelength range. A linear accelerator will feed these storage rings in topping up mode as well as serve as an electron source for a short pulse facility built on its extension.

Tango based control system at SOLARIS Synchrotron
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

Transverse coherent instabilities in storage rings with harmonic cavities
Many current and future synchrotron light sources employ harmonic cavities to lengthen the electron bunches in order to reduce the emittance dilution caused by intrabeam scattering. In some cases, the harmonic cavities may be tuned to fulfill the flat potential condition. For this condition, a large increase in the threshold currents of transverse coupled-bunch instabilities has been predicted and
