Work life balance and taxation in the Netherlands

In the Netherlands, the role of the woman in society has changed drastically in the past century. Furthermore, over the past 50 years, marriage between man and woman lost its dominant position to alternative forms of cohabitation. These developments in society and civil law are also reflect-ed in the Dutch Personal Income Tax Act (PITA) and the Dutch Gift and Inheritance Tax Act (GITA) and will be

Non-binary phase gratings for x-ray imaging with a compact Talbot interferometer

X-ray imaging using a Talbot-Lau interferometer, consisting of three binary gratings, is a well-established approach to acquire x-ray phase-contrast and dark-field images with a polychromatic source. However, challenges in the production of high aspect ratio gratings limit the construction of a compact setup for high x-ray energies. In this study we consider the use of phase gratings with triangul

Out-of-hospital cardiac arrest at place of residence is associated with worse outcomes in patients admitted to intensive care : a post-hoc analysis of the Targeted Temperature Management trial

BACKGROUND: The majority of out-of-hospital cardiac arrests (OHCAs) occur at place residence, which is associated with worse outcomes in unselected prehospital populations. Our aim was to investigate whether location of arrest was associated with outcome in a selected group of initial survivors admitted to intensive care.METHODS: This is a post-hoc analysis of the Targeted Temperature Management a

Geochemical composition of Baltic benthic foraminifera collected and cultured over a large salinity gradient.

Some of the most significant challenges in paleoclimate research arise from the need to both understand and reduce the uncertainty associated with proxies for climate reconstructions. These challenges were further highlighted in connection with the IODP Exp.347 Baltic Sea Paleoenvironment. We have investigated temperature and salinity proxies through a combination of field-and culture-based benthi

Skjutvapens- och explosionsvåld

Det skjutvapenrelaterade våldet i Sverige har ökat kraftigt sedan 1990-talet, och trots att hela Sverige är drabbat sticker Region Skåne och då främst Malmö ut. Även om en stor del av skottlossningarna riktas mot byggnader och fordon dör och skadas årligen ett tiotal personer i staden. Även explosionsvåldet har ökat både i landet och i Malmö och det kan vara ett tecken på ett trendbrott inom den gGun-related violence in Sweden has increased dramatically since the 1990s, and while the entire country has been affected, the Skåne region and Malmö in particular stand out. Although many of the shootings are directed at buildings and vehicles, more than ten people are killed and injured in the city every year. Violence caused by explosives has also increased both in Malmö and in the country as a

Two-pion production in photon-photon collisions

We calculate within chiral perturbation theory the cross section for γγ→π0π0 and γγ→π+π- to next-to-leading order. The first process only depends on the one-loop contributions and forms a test of chiral perturbation theory. We also calculate the pion electromagnetic form factor and compare it to recent data.

Chiral perturbation theory and the evaluation of 1 Nc-corrections to nonleptonic decays

We present a discussion of the treatment of 1 Nc-corrections in chiral perturbation theory for nonleptonic weak processes. We compare the approach with an explicit cutoff and dimensional regularization in chiral perturbation theory and present evidence that they are equivalent. The quadratic dependence on the cutoff can be subtracted consistently at each level of 1 Nc. We discuss the identificatio

The chiral anomaly in non-leptonic weak interactions

The interplay between the chiral anomaly and the non-leptonic weak hamiltonian is studied. The structure of the corresponding effective lagrangian of odd intrinsic parity is established. It is shown that the factorizable contributions (leading in 1/Nc) to that lagrangian can be calculated without free parameters. As a first application, the decay K+→π+π0γ is investigated.

Corrections to the Weiss-Zumino term in chiral perturbation theory

All the terms needed to cancel the divergences appearing in one-loop calculations involving the Wess-Zumino term are obtained. We apply this result to the Pγγ and PPPγ vertices, fixing the finite part of the coefficients of the O(p6) terms in the lagrangian with vector meson contributions. In all the cases the corrections improve the agreement between the theoretical predictions and experimental d

On the tensor formulation of effective vector lagrangians and duality transformations

Using two different methods inspired by duality transformations we present the equivalence between effective Lagrangians for massive vector mesons using a vector field and an antisymmetric tensor field. This completes the list of explicit field transformations between the various effective Lagrangian methods to describe massive vector and axial vector mesons. Our method automatically generates the

Open tools for software engineering : Validation of a theory of openness in the automotive industry

Context: Open tools (e.g., Jenkins, Gerrit and Git) offer a lucrative alternative to commercial tools. Many companies and developers from OSS communities make a collaborative effort to improve the tools. Prior to this study, we developed an empirically based theory for companies’ strategic choices on the development of these tools, based on empirical observations in the telecom domain. Aim: The ai

Master equation approach to DNA breathing in heteropolymer DNA

After crossing an initial barrier to break the first base-pair (bp) in double-stranded DNA, the disruption of further bps is characterized by free energies up to a few kBT. Thermal motion within the DNA double strand therefore causes the opening of intermittent single-stranded denaturation zones, the DNA bubbles. The unzipping and zipping dynamics of bps at the two zipper forks of a bubble, where

Blinking statistics of a molecular beacon triggered by end-denaturation of DNA

We use a master equation approach based on the Poland–Scheraga free energy for DNA denaturation to investigate the (un)zipping dynamics of a denaturation wedge in a stretch of DNA that is clamped at one end. In particular, we quantify the blinking dynamics of a fluorophore–quencher pair mounted within the denaturation wedge. We also study the behavioural changes in the presence of proteins that se

Ellipsoidal particles driven by intensity gradients through viscous fluids

We investigate the vdrift velocity vdrift of ellipsoidal polarizable particles (ellipsoids and coated ellipsoids), driven through a viscous fluid by an electric or electromagnetic field intensity gradient. At low Reynolds number and in the dipole approximation vdrift is proportional to the square of the principal axis along the direction of motion multiplied by a form factor, which is weakly depen

QCD aspects of leptoquark production at HERA

If a leptoquark is produced at HERA as a narrow resonance, various effects tend to broaden the measurable mass distribution considerably. These effects are discussed here, with special emphasis on initial- and final-state QCD radiation. A proper understanding is important to assess the significance of data and to devise strategies for better mass reconstruction.
