Contrary to the general trend in European countries since the 2000s, Sweden has neither restricted its migration policy nor limited the rights of migrants. This changed with the ‘refugee crisis’ of 2015 when the government introduced policy changes to curb the number of arrivals and impede the granting of residence permits. Civil society organizations are significantly involved in the reception of

IntroductionSports‐related injuries and illnesses in Paralympic sport (SRIIPS) is a concern, but knowledge about the aetiology and risk factors is limited. The aim of this study was to describe the annual incidence, type and severity of injuries and illnesses among Swedish Paralympic athletes and to assess risk factors.MethodsSwedish Paralympic athletes (n=107) self‐reported SRIIPS every week duri

We present a detailed study of the effect of gate-oxide-related defects (traps) on the small-signal radio frequency (RF) response of III-V nanowire MOSFETs and find that the effects are clearly identifiable in the measured admittance parameters and in important design parameters such as h21 (forward current gain) and MSG (maximum stable gain). We include the identified effects in a small-signal mo

High-frequency performance of vertical InAs/InGaAs heterostructure nanowire MOSFETs on Si is demonstrated for the first time for a gate-last configuration. The device architecture allows highly asymmetric capacitances, which increases the power gain. A device with Lg = 120 nm demonstrates fT = 120 GHz, fmax = 130 GHz and maximum stable gain (MSG) = 14.4 dB at 20 GHz. These metrics demonstrate the

The ever increasing demand for faster and more energy-efficient electricalcomputation and communication presents severe challenges for the semiconductor industry and particularly for the metal-oxidesemiconductorfield-effect transistor (MOSFET), which is the workhorse of modern electronics. III-V materials exhibit higher carrier mobilities than the most commonly used MOSFET material Si so that the

Rice straw is regarded as one of the main cereal straws that are produced every year in substantial amounts. Typically, rice straw is burned by farmers as they could not find a more promising technique to dispose it. This burning produces particulates and carbon monoxide causing many adverse effects on the environment and the public health, and finding a way to efficiently utilise this biowaste re

Co-feeding of renewable feedstocks in general, and lignin streams in particular, in petroleum refineries is an attractive means of increasing the proportion of renewable fuel. Four separate units in an integrated refinery can be envisioned using lignin as a feedstock: the hydrotreater, the fluidised catalytic cracker, the hydrocracker and the slurry hydrotreater. A conceptual process design study,

State reforms adopted in the 1680s prevented the largest copperworks in the Oldenburg Monarchy, Røros, from shutdown. They appear to be a forerunner in Europe. The changes ensured supply deliveries and regular wage payments through spread of ownership, delegating more responsibilities to the Director and managers and introducing complex control mechanisms and state monitoring of the accounts and d

The cost-effectiveness of smoking cessation interventions is well documented. However, most studies are based on randomized controlled trials (RCTs) and provide little information on the differences between subgroups. This study assessed the relative cost-effectiveness of smoking cessation interventions offered to various subgroups of smokers, based on real-life data. Regression analyses provided

Thanks to simple and straightforward calculation methods it is rather easy to estimate gas temperatures in small- or medium sized enclosures; however, the problem becomes more complex if fire safety analyses are to be performed in large spaces where the hot gas layer cannot be regarded as uniform. Using a multi-zone modelling concept could be a good alternative for such situations.

Hushållen står för cirka 26 % av den årliga energianvändningen i EU. Som följd av EU:s direktiv om energiprestanda i byggnader har det genomförts internationella initiativ i Europa för att hjälpa länder att definiera och inkludera riktlinjer i sina egna byggregler, till exempel för att etablera konceptet nollenergibyggnader. Detta koncept inkluderar passiv-teknik for energibesparande byggande, eneHouseholds are responsible for approximately 26 % of the annual energy use in the EU. Following the EU-directives regarding energy performance in buildings, international initiatives have been taken in Europe to help countries to define and include guidelines in their own building codes, for example, to establish the concept of zero energy buildings, ZEBs. This concept includes passive building en

Food security is one of the world’s greatest challenges. The current food system shows an entanglement across the globe which means that local farmers reliant on subsistence agriculture no longer operate in isolation of larger-scale processes within the global economy or the changing biophysical system of the planet. The persistently high number of undernourished people, volatile food prices, incr

A short opinion piece on the social and political ramifications of our increased dependency on online products such as Netflix, YouTube and Facebook during the corona crisis.

Genom planmonopolet har kommunerna ensamrätt om att kunna skapa byggklara tomter. Men empirin visar att kommunerna underproducerar dessa byggrätter. Det skapar en rad problem på bostadsmarknaden. Ingemar Bengtsson, lektor i fastighetsvetenskap vid Lunds universitet redogör för konsekvenserna.
