Optical properties of humic-like substances (HULIS) in biomass-burning aerosols

We present here the optical properties of humic-like substances (HULIS) isolated from the fine fraction of biomass-burning aerosol collected in the Amazon basin during the LBA-SMOCC (Large scale Biosphere atmosphere experiment in Amazonia - SMOke aerosols, Clouds, rainfall and Climate) experiment in September 2002. From the isolated HULIS, aerosol particles were generated and their scattering and

Spectral light absorption by ambient aerosols influenced by biomass burning in the Amazon Basin. I : Comparison and field calibration of absorption measurement techniques

Spectral aerosol light absorption is an important parameter for the assessment of the radiation budget of the atmosphere. Although on-line measurement techniques for aerosol light absorption, such as the Aethalometer and the Particle Soot Absorption Photometer (PSAP), have been available for two decades, they are limited in accuracy and spectral resolution because of the need to deposit the aeroso

Optical and physical properties of aerosols in the boundary layer and free troposphere over the Amazon Basin during the biomass burning season

As part of the Large Scale Biosphere-Atmosphere Experiment in Amazonia - Smoke, Aerosols, Clouds, Rainfall and Climate (LBA-SMOCC) campaign, detailed surface and airborne aerosol measurements were performed over the Amazon Basin during the dry to wet season from 16 September to 14 November 2002. Optical and physical properties of aerosols at the surface, and in the boundary layer (BL) and free tro

"Missing" cloud condensation nuclei in peat smoke

We characterized particulate emissions from vegetation fires by burning Indonesian and German peat and other biomass fuels in a controlled laboratory setting. By measuring cloud condensation nuclei (CCN) both as a function of particle diameter (dp) and supersaturation (S), we discovered particles in peat smoke that were not activated to cloud droplets at high S (1.6%). These hydrophobic particles

DATAEKONOMIER : Om plattformar, tredjepartsaktörer och behovet av transparens på digitala marknader

Mycket av den digitala datainsamlingen av personers information sker utan att konsumenterna är medvetna om det eller ens har någon praktisk möjlighet att påverka. Detta får direkta konsekvenser för konkurrensens förutsättningar, men aktualiserar också frågan om hur dataskydd, konkurrens och det bredare konsumentskyddet förhåller sig till varandra och, i förlängningen hur de olika tillsynsmyndighet

Interpretation of variation in omics data : Applications in proteomics for sustainable agriculture

Biomarkers are used in molecular biology to predict characteristics of interest and are applied in agriculture to accelerate the breeding of target traits. Proteomics has emerged as a promising technology for improved markers by providing a closer view to the phenotype than conventional genome-based approaches. However, a major challenge for biomarker development is that the identified biological

The Orthodox "Unorthodox" : From Populism to Pluralism

During the last decade the link between religion and right-wing populism has been underlined by scholars, viewing the latter as a form of ‘religious backlash’ and encouraging progressives to fight back. However, by setting the religious against the secular, these arguments, paradoxically, have contributed to the development of populism—by enforcing what Ryszard Bobrowicz and Johanna Gustafsson Lun

Tema: Det exceptionella Amerika – dåtid/nutid

Specialnummer av Statsvetenskaplig tidskrift med artiklar och litteraturgranskningar om det exceptionella USA.Special edition of Journal of Political Science on the theme The exceptional America then and now.

Give me history or give me death! : Politik och historiebruk i USA

This article deals with uses of history and the combination of politics and the past from an American point of view. On one hand, the time span is long, with references dating back to Roman history, the war of independence and more recent events as the Vietnam War. On the other hand, it is interpretations of history here and now that are is analyzed. Another point of departure is different histori

VoI-informed decision-making for SHM system arrangement

Structural health monitoring systems have been widely implemented to provide real-time continuous data support and to ensure structural safety in the context of structural integrity management. However, the quantification of the potential benefits of structural health monitoring systems has not yet attracted widespread attention. At the same time, there is an urgent need to develop strategies, suc

Systematic Framework to Assess Social Impacts of Sharing Platforms

(1) BackgroundResearch and user experience suggests both positive and negative social impacts resulting from practices in the sharing economy: social cohesion vs. gentrification; inclusiveness vs. discrimination; flexible employment vs. exploitation. However, as yet, there is no framework for understanding or assessing these social impacts holistically.(2) ObjectiveWe aim to improve understanding

Enhancing prediction and causal inference in metabolic dyshomeostasis

This thesis is focused on two globally prevalent diseases: i) non-alcoholic fatty liver disease (NAFLD) and ii) type 2 diabetes (T2D), with an overall aim of improving prediction and causal inference in the context of these conditions. Our projects were mainly conducted using IMI DIRECT and UK Biobank datasets including multi-omics data, extensive environmental exposures, and biological intermedia

Dissolved organic matter across terrestrial and aquatic systems : sources, chemistry and microbial processing

The movement of DOM from terrestrial to aquatic systems is a globally significant flux affecting both carbon sequestration and CO2 emissions. Here, DOM dynamics were investigated in terrestrial and aquatic systems within the context of this carbon flux. The overall aim was to investigate the source and chemistry of DOM and determine how chemistry is affected by microbial processing of DOM. In the

J/ψ elliptic and triangular flow in Pb-Pb collisions at √sNN = 5.02 TeV

The inclusive J/ψ elliptic (v2) and triangular (v3) flow coefficients measured at forward rapidity (2.5 < y < 4) and the v2 measured at midrapidity (|y| < 0.9) in Pb-Pb collisions at sNN = 5.02 TeV using the ALICE detector at the LHC are reported. The entire Pb-Pb data sample collected during Run 2 is employed, amounting to an integrated luminosity of 750 μb−1 at forward rapidity and 93 μb−1 at mi

Search for pairs of scalar leptoquarks decaying into quarks and electrons or muons in √s = 13 TeV pp collisions with the ATLAS detector

A search for new-physics resonances decaying into a lepton and a jet performed by the ATLAS experiment is presented. Scalar leptoquarks pair-produced in pp collisions at s = 13 TeV at the Large Hadron Collider are considered using an integrated luminosity of 139 fb−1, corresponding to the full Run 2 dataset. They are searched for in events with two electrons or two muons and two or more jets, incl
