Bilingualism has become increasingly prevalent globally, with about half of the world's population being bilingual by 2012. This growing trend has prompted cognitive research to explore the effects of bilingualism on executive functions. The Bilingual Advantage (BA) theory posits that bilingual individuals experience enhanced cognitive abilities due to their practice in managing multiple langu

Stereotypa föreställningar och negativ behandling av äldre finns dokumenterade sedan antik tid. Numera används begreppet ålderism, vilket avser fördomar och diskriminering mot äldre. Ibland har begreppet också definierats som något som handlar om ålder över hela livsloppet. Den här antologin består av 15 kapitel där forskare belyser ålderismens varierade uttrycksformer och komplexitet. I antologin

Extensive COVID-19 information can generate information overload and confusion. Denmark and Sweden adopted different COVID-19 management strategies. Aim This study aimed to compare search strategies, perceptions and effects of COVID-19 information, in general and specifically in social media, in residents in Denmark and Sweden.

Mid-infrared polarization spectroscopy was applied to detect HCl at trace level in an atmospheric pressure premixed H2/O2/Ar flame with chloroform seeding. Detection sensitivity and potential interference from water lines was investigated.

Mid-IR polarization spectroscopy (IRPS) and laser-induced fluorescence were applied for detection of CH4 and ethane in 1 atm cold flows and flames. The dependence of IRPS and IRLIF signal of CH4 on different buffer gases, including He, Ar, N2, and CO2 were studied. Simultaneous measurements of IRPS and IRLIF signals allowed a direct comparison of the two techniques. IRPS was superior in detection

Technical developments for the detection of formaldehyde using laser-induced fluorescence were presented. A technique for simultaneous detection of formaldehyde and OH using one laser system was presented. The combined formaldehyde and OH technique was applied in laboratory flames and a small spark-ignition engine. The iodine measurement was performed in a cell using the second harmonic of the sin

This paper presents technical developments for the detection of formaldehyde (CH2O) using laser-induced fluorescence. The easily accessible third harmonic of the Nd:YAG laser at 355 nm was used for excitation of formaldehyde. In order to investigate potential background fluorescence, e.g., from large molecules such as polyaromatic hydrocarbons, special attention was paid to investigating the possi

Mobility is essential to our modern world to move people and goods. However, mobility has also its downside as transport sectors are substantial emitters of greenhouse gases and air pollutants. Increasingly energy efficient combustion engines and turbines, as well as electrification and carbon-neutral fuels, will reduce the climate impacts of transportation. When such technologies are combined wit

Efficient and clean production of electrical and mechanical energy for use in industry, transportation and propulsion is currently a concern. The transition from fossil fuels to biofuels involves challenges related to the fuel composition and combustion, as well as methods to increase engine fuel flexibility. One potentially useful tool under development is Plasma Assisted Combustion (PAC), where

First Published in 1991. This is Volume 13 in a series of Transportation Studies. It contains 2 parts of the proceedings of a Conference held at Stockholmsmassan, Alvsjo, Sweden, 21-24 May 1989, organized by the Swedish Board of Transport in co-operation with the Department of Traffic Planning and Engineering, Lund Institute of Technology.

How does violent conflict affect the spread of Covid-19? In this paper we analyze how violent conflict influences the adoption of preventative measures and infection rate in a very poor, conflict-affected country, Burkina Faso. We use a unique panel of 1,919 households surveyed during the first six months of the Covid-19 pandemic in 2020 and merge these data with indicators of violence at the muniHow does violent conflict affect the spread of Covid-19?

BackgroundThe risk of developing Alzheimer’s disease (AD) is modulated by genetic and environmental factors. Early-life stress (ELS) exposure during critical periods of brain development can impact later brain function and health, including increasing the risk of developing AD. Microglial dysfunction and neuroinflammation have been implicated as playing a role in AD pathology and may be modulated

In this work we present a setup for laser-induced breakdown spectroscopy (LIBS) employing a polarization filtering approach and use it for gas diagnostics. A one parts-per-million (ppm) detection sensitivity is achieved for hydrogen atoms.

Disasters and climate change impacts, as well as increased water demand, pose serious risks to the provision of sustainable urban water services, e.g., drinking water, sanitation, and safe drainage, especially in cities. These challenges call for a transition toward improved water management, including considerations of “resilience.” However, because the resilience concept has multidisciplinary or

Reformer som fokuserar på ökad privatisering och konkurrens bland utförare och ökad valfrihet för individer(patienter, elever, brukare)har införts i svensk hälso-och sjukvård, skola och omsorg. Individer ska kunnavälja bland offentliga och privata utförare som finansieras med offentliga medel och som förväntas konkurrera om elever, patienter och brukare på en reglerad marknad–en välfärdsmarknad.I
