Popular Abstract in Swedish I vår omgivning finns många gasformiga ämnen, vars egenskaper är sådana att de kan mätas med optiska metoder. Härvid kan man utnyttja det unika spektroskopiska fingeravtryck ämnena har. Det vill säga, att varje ämne absorberar ljus av olika färg (våglängd) på ett unikt sätt. Likaså har vissa ämnen sådana egenskaper, att då de belyses med en viss våglängd sänder de ut enMulti-spectral lidar (light detection and ranging) techniques have been developed and employed in various environmental studies, ranging from concentration mapping of volcanic emissions to fluorescence imaging of historical monuments. In both absorption measurements of gaseous species and fluorescence imaging of stones, multiple wavelength excitation and multiple wavelength detection have been app

Birds migrating between distant locations regularly perform long continuous flights lasting several days. What compass mechanism they use is still a mystery. Here, we use a novel approach, applying an individual-based model, taking compass mechanisms based on celestial and geomagnetic information and wind into account simultaneously, to investigate what compass mechanism likely is used during long

For the development of single–ion irradiation system for living cells at the Lund Ion Beam Analysis facility (LIBAF) newly developed pre-cell (PC) detectors have been investigated. Central to the thesis is the fabrication and initial characterization of more than 100 ultra-thin silicon detectors having different thicknesses down to 5 μm with active areas ranging from 0.71 to 0.172 mm2, to be used

Popular Abstract in Swedish Avhandlingen syftar till att utifrån 11-åriga barns berättelser om sina familjer och hur de själva uppfattar sina familjer och sin fostran beskriva, analysera, förstå och tolka villkoren för denna fostrans- och socialisationsprocess samtidigt som den pågår. Forskningsproblemet kan formuleras: hur och vad uppfattar och berättar barn om sina upplevelser av familjeliv och The thesis aims to describe, analyse and interpret the conditions of the upbringing process and the socialization process in a group of eleven-year-olds while the process is still ongoing, and to do this with the help of the eleven-year-olds? narrations about their families and about how the children themselves view their families and their upbringing. The research approach is inspired by phenomen

In this paper, we present geochronological, geochemical and palaeomagnetic results from the Hlagothi Complex and a NW-trending dolerite dyke swarm on the southeastern region of the Kaapvaal Craton in northern KwaZulu-Natal, South Africa. The Hlagothi Complex consists of layered sills of meta-peridotite, pyroxenite and gabbro intruding into the Pongola Supergroup. U-Pb baddeleyite ages on the Hlago

In the beginning of the COVID-19 pandemic, several super spreader events occurred during singing in choirs, which lead to an increased attention to airborne transmission of SARS-CoV-2, the virus causing COVID-19. Since then, aerosol generation from singing has been studied in more detail, however, only from healthy subjects. In this study, we collected aerosol particles in the exhaled breath of 40

In this work, the effects of thermal buoyancy and rotation angle on the hydrodynamics and mixed convection heat transfer characteristics over four heated identical square cylinders placed in a parallel horizontal channel are numerically studied. For the flow field, the Lattice Boltzmann method (LBM) with multiple relaxation time collision operator (MRT) is implemented and the Bhatnagar-Gross-Ktook

After demonstration of a 23% power conversion efficiency, a high operational stability is the next most important scientific and technological challenge in perovskite solar cells (PSCs). A potential failure mechanism is tied to a bias-induced ion migration, which causes current–voltage hysteresis and a decay in the device performance over time. Herein, alkali salts are shown to mitigate hysteresis

Popular Abstract in Swedish I Nationalencyklopedin står det att spektroskopi är en metod för att studera molekyler, atomer och atomkärnor med hjälp av dess spektra. Man använder både elektromagnetisk strålning och partikelstrålning inom spektroskopin. Spektroskopi används inom astronomi, kemi, fysik och medicin. Ordet spektroskopi kommer ifrån latinet och betyder att titta vilket förklaras av att

The rapid progression of the electrification of road transport in many countries urges the need to make informed decisions on the location and size of the required charging infrastructure. This paper’s main contribution is a novel method to position fast-charging stations based on the transportation energy demand and to evaluate the performance of such charging infrastructure. Depending on their r

BACKGROUND: Transmission of coronavirus disease 2019 (COVID-19) can occur through inhalation of fine droplets or aerosols containing infectious virus. The objective of this study was to identify situations, patient characteristics, environmental parameters, and aerosol-generating procedures (AGPs) associated with airborne severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus.METHODS:

The ability of echocardiography to diagnose sources of embolism and the role of the examination in the prediction of thromboembolism are reviewed. In addition, the yield of transthoracic (TTE) and transoesophageal echocardiography (TEE) is analysed in patients with suspected embolism and guidelines are proposed for performing echocardiography in this setting. In general, echocardiography is reliab

Objectives The purpose of the thesis is to investigate how a new logistic set-up can lower the transportation cost of OEM articles. Four objectives are identified to that end: identify the OEM articles, map their flow, create simulation tool and examine what logistics set-up is suitable. Background The increasing rate of globalization has put immense pressure on the world’s infrastructure. As a re
