The laser wake-field accelerator (LWFA) traditionally produces high brightness, quasi-monoenergetic electron beams with Gaussian-like spatial and angular distributions. In the present work we investigate the generation of ultra-relativistic beams with ring-like structures in the blowout regime of the LWFA using a dual stage accelerator. A density down-ramp triggers injection after the first stage

The first positive genome-wide association study on gestational length and preterm delivery showed associations with a gene involved in the selenium metabolism. In this study we examine the associations between maternal intake of selenium and selenium status with gestational length and preterm delivery in 72,025 women with singleton live births from the population based, prospective Norwegian Moth

Background: Methylisothiazolinone (MI) has caused an unprecedented epidemic of contact allergy in Europe and elsewhere. Subsequently, regulatory action has been taken, at least in Europe, aiming at reducing risk of MI sensitization. Objective: To follow-up on the prevalence of contact allergy to MI in consecutively patch tested patients and assess the spectrum of products containing MI or methylch

AimsCan drug abuse (DA) be transmitted psychologically between adult siblings consistent with a social contagion model?MethodsWe followed Swedish sibling pairs born in 1932-1990 until one of them, sibling1 (S1), had a first DA registration. We then examined, using Cox regression, the hazard rate for a first registration for DA in sibling2 (S2) within 3 years of a first DA registration in S1 as a f

I decennier var juridiken ett mansdominerat område. Men i slutet av 1800-talet började även kvinnor studera juridik. De måste dock överkomma många hinder innan de fick praktisera den. Artikeln belyser några av de kvinnliga pionjärerna inom juridiken och deras livsöden.

Som följd av den globala finanskrisen befinner sig nu Sverige i en djup ekonomisk kris – troligen den djupaste sedan 1930-talet. Det dystra läget har skapat ett intresse för kriser i vår historia. Lars Jonung diskuterar i denna artikel vad vi kan lära från tidigare finanskriser, vilken vägledning de ger oss beträffande dagens kris och vad de säger om framtiden.

Through an analysis of the FDA’s approval of the controversial anti-influenza drug Relenza (zanamivir), we interrogate distinct social scientific theories of pharmaceutical regulation. We investigate why, despite internal negative opinions and an Advisory Committee’s non-approval recommendation, the FDA approved Relenza in the late 1990s. Based on a close reading of FDA documents, we show how agen

Det finns många ”första” knutna till Karin Kock. Hon var den första kvinnan som gjorde karriär som akademisk nationalekonom, blev docent i nationalekonomi, fick professors namn i nationalekonomi, utnämndes till statsråd och till chef för en större statlig myndighet. Hon var en hårt arbetande och framgångsrik pionjär i den manliga värld som national- ekonomi och ekonomisk politik utgjorde. Hon röjd

Purpose: The purpose of this study is to enhance the thermal performance in the labyrinth channel by different ribs shape. The labyrinth channel is a relatively new cooling structure to decrease the temperature near the trailing region of gas turbine. Design/methodology/approach: Based on the geometric similarity, a simplified geometric model is used. The k − ω turbulence model is used to close th

The study aim was to report survival and morbidity of all patients in Sweden with peritoneal mesothelioma treated with cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) as well as investigate whether the survival has increased on a population level since this treatment was nationalized 2011. Study data were collected from the Swedish HIPEC registry and the Swedish N

This paper models ‘no war, no peace’ situations in a game theoretical framework where two countries are engaged in a standoff over a military sector. The first main objective is to identify rational grounds for such situations and, more precisely, for the explicit equilibria that lead to such situations. It is demonstrated that both countries gain the same payoff from being in this continuous stat

Glucose-dependent insulinotropic polypeptide (GIP) receptor knockout (KO) mice are tools for studying GIP physiology. Previous results have demonstrated that these mice have impaired insulin response to oral glucose. In this study, we examined the insulin response to intravenous glucose by measuring glucose, insulin and C-peptide after intravenous glucose (0.35 g/kg) in 5-h fasted female GIP recep

This article is a revised version of a keynote given at the 18th Nordic Conference on Systematic Theology: Hope in Dark Times, held in Stavanger on 10–13 January 2019. The aim of the article is to ponder how Jewish and Christian discourses on hope can contribute in a critical way to contemporary political and philosophical discussions of hope. Taking its cue from the biblical idea of messianic red
