Solid state klystron modulators are typically based on oil-immersed pulse transformers due to their high performance, robustness, simplicity and straightforward design. However, the size of such transformers are highly impacted by pulse power, output voltage, pulse length, and required rise time; key parameters which are difficult to combine in long pulse high power linac applications. In this pap

Previous studies report that dental caries is partially heritable, but there is uncertainty in the magnitude of genetic effects and little understanding of how genetic factors might influence caries progression or caries subtypes. This study aimed to estimate the relative importance of genetic and environmental factors in the etiology of different caries outcomes using a twin-based design. Analysi

Modal choice is a prominent concept within transport studies. However, the term is often used quite loosely, with little known about the factors lying behind the choice, the alternatives available to a person, and whether the person had a ‘choice’ to begin with. This study draws on a travel survey among older people living in Sweden’s large metropolitan regions. The questions posed as part of this

This Article focuses on the accountability challenges raised by the increased involvement of Private Military and Security Companies (PMSC) in migration control. I argue that migration control activities outsourced to PMSC can be classified as high-risk operations for the purposes of the application of relevant business and human rights standards. This reclassification of migration control activit

This article focuses on the proportionality analysis carried out by international investment tribunals when the protection of foreign investment adversely impacts the protection of human rights. International investment arbitrators are increasingly called to adjudicate awards which require a 'balancing' between the so-called rights of investors, protected as they are by relevant international inve

In this chapter I try to discern the shape of a phantom. The phantom is the people in a democracy. The first argument which will be put forward is that democracy cannot exist without such a phantom. But this phantasmagorical presence of the people in society can threaten the very democracy which it makes possible, in two ways. First, the phantom can prove to be no more than that – a mere figment o

Mi Lennhag reviews Vory: den ryska supermaffian (The Vory: Russia’s Super Mafia) by Mark Galeotti (translated by Manne Svensson). The book examines organized crime in the Soviet Union and in post-Soviet Russia. Historical, political and cultural contexts help explaining the Russian mafia and the phenomenon vory. Galeotti pictures a Russian society where politics and organized crime remain closely

The number of patients with Alzheimer's disease (AD) is likely to triple in a few decades as the world's population ages. Given the high personal and societal burden of this disease, it is imperative to identify its risk factors. The etiology of AD is still not fully understood, but environmental factors have emerged as plausible important risk factors on the population-level. In this short review

Augmentation of heat transfer must always be judged against an additional pressure loss. To this context, this paper explores slitted ribs on the turbulent flow and heat transfer characteristics in rectangular cooling channels with an aspect ratio of 4:1. A verified v2f turbulence model is applied in the present numerical simulations in the Reynolds number range from 20,000 to 80,000. The flow and

Usages of the Past in Roman Historiography contains 11 articles on how the Ancient Roman historians used, and manipulated, the past. What did they seek to accomplish by participating in its re-creation, what tools did they have at their disposal to do so, and which underlying conceptualisations of history can we glimpse behind their efforts? Key themes include the impact of the transformation from

Possibilities to perform pre- and post-seismic groundwater chemical comparisons on regional groundwater flow systems are rare due to lack of data and observations. The Kumamoto earthquake provides an unusual opportunity to improve the knowledge on earthquake hydrology and earthquake effects on hydrochemistry of groundwater due to a wealth of pre- and post-quake observations. We analyzed 12 physioc

Objectives: Using a reversible multistate model, we prospectively examined neuropsychiatric (NP) events for attribution, outcome and association with health-related quality of life (HRQoL), in an international, inception cohort of systemic lupus erythematosus (SLE) patients. Methods: Annual assessments for 19 NP events attributed to SLE and non-SLE causes, physician determination of outcome and pa

Aims: The aim of this study was to test a Child-Centred Health Dialogue model for primary prevention of obesity for 4-year-old children in Child Health Services, for its feasibility and the responsiveness of its outcomes. Methods: A feasibility study was set up with a non-randomised quasi-experimental cluster design comparing usual care with a structured multicomponent Child-Centred Health Dialogu

BACKGROUND: The Child Health Services in Sweden is a well-attended health promoting setting, and thereby has an important role in promoting healthy living habits in families with young children. Due to lack of national recommendations for health dialogues, a Child Centred Health Dialogue (CCHD) model was developed and tested in two Swedish municipalities. The aim of this study was to explore paren
