Otitis media with effusion (OME) is a common inflammatory disease, primarily affecting children. OME is defined as a chronic low-grade inflammation of the middle ear (ME), without any signs of infection and with effusion persisting in the ME for more than three months. The precise pathogenesis is, however, not fully understood. Here, we comprehensively characterized and compared the host immune re

Biofilm formation by Streptococcus pyogenes (GAS) in model systems mimicking the respiratory tract is poorly documented. Most studies have been conducted on abiotic surfaces, which poorly represent human tissues. We have previously shown that GAS forms mature and antibiotic-resistant biofilms on physiologically relevant epithelial cells. However, the role of the substratum, extracellular matrix (E

In this study, the photoelectrochemical behavior of electrodeposited FeNiOOH/Fe2O3/graphene nanohybrid electrodes is investigated, which has precisely controlled structure and composition. The photoelectrode assembly is designed in a bioinspired manner where each component has its own function: Fe2O3 is responsible for the absorption of light, the graphene framework for proper charge carrier trans

How predators select on conspicuous prey traits is not well understood. We used a laboratory setup to investigate the role of learning in predator choice of conspicuous visual traits. We used a generalist predator, the great tit, and coloured wings of males of two species of damselflies as prey. Wing pigmentation differs between the species in colour (green vs. blue) and size (large vs. small). Wi

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
