Search for chargino and neutralino production in final states with a Higgs boson and missing transverse momentum at s =13 TeV with the ATLAS detector

A search is conducted for the electroweak pair production of a chargino and a neutralino pp→χ1±χ20, where the chargino decays into the lightest neutralino and a W boson, χ1±→χ10W±, while the neutralino decays into the lightest neutralino and a Standard Model-like 125 GeV Higgs boson, χ20→χ10h. Fully hadronic, semileptonic, diphoton, and multilepton (electrons, muons) final states with missing tran

När klimatkrisen kommer

To the publicly elected politicians of Sweden: Two out of three Swedes are worried about climate change since it poses a significant threat to our safety, freedom and democracy. This pamphlet will help you to better understand how our society will be affected by the climate crisis if we do not urgently take appropriate measures. The pamphlet will also give you strategies for how to counteract this

Search for excited electrons singly produced in proton–proton collisions at √s=13Te with the ATLAS experiment at the LHC

A search is conducted for the electroweak pair production of a chargino and a neutralino pp→χ1±χ20, where the chargino decays into the lightest neutralino and a W boson, χ1±→χ10W±, while the neutralino decays into the lightest neutralino and a Standard Model-like 125 GeV Higgs boson, χ20→χ10h. Fully hadronic, semileptonic, diphoton, and multilepton (electrons, muons) final states with missing tran

Mechanisms and regulations of priming effects in soil

Soil organic matter (SOM) plays a significant role in the global carbon (C) and nutrients cycles, not only since SOM is a major storage reservoir of C and plant nutrients, but also since microbial decomposition of SOM releases large quantities of CO2 to the atmosphere. The accelerated or reduced turnover rate of SOM after the input of labile C compounds is a phenomenon known as the priming effect

Properties and fungal decomposition of iron oxide-associated organic matter

Soil organic matter (SOM) stores the largest quantity of C in terrestrial ecosystems. Most SOM can be decomposed by microorganisms and released as CO2 into the atmosphere. The remaining fraction of SOM can be resistant against microbial decomposition over centuries to millennia. Changes in the magnitude of this stable SOM pool can have a substantial effect on the atmospheric CO2 concentration and

Precipitation phase determination in cold region conceptual models - analysis and method development

Precipitation phase uncertainty is a known source of error in conceptual models used for many hydrological, climatological, and environmental applications. These conceptual models often use the simple approach of calibrating an air temperature threshold (TRS) over a large area irrespective of physiographic characteristics such as distance to the ocean and topographic relief. Conceptual modeling re

Outcome in Juvenile Idiopathic arthritis : a population-based study from Sweden

Background: As the treatment arsenal for children with juvenile idiopathic arthritis (JIA) has expanded during the last decades, follow-up studies are needed on children diagnosed in the era of biological treatment to evaluate if this has improved the outcome. Our aim was to study the epidemiology and outcome of JIA in southern Sweden using a population-based cohort of children with a validated di

International Studies on Enactment of Children´s Rights in Education : 30 researchers from non-western countries

The UN Convention on the Rights of the Child is a human rights legal document decided and adopted by the UN General Assembly in November 1989. This international convention has had a major impact on children’s rights, policies and legislation in many countries around the world. Another prominent feature of the development, however, is the lack of research in many areas on implementation of childre

Children´s Rights in Schools : From International Initiatives to Local Implementation

The UN Convention on the Rights of the Child is a human rights treaty adopted by the UN General Assembly in 1989, which has had a major impact on children’s rights, policies and legislation in many countries around the world. This paper describes longstanding experiences of running a Sida-funded training programme on children’s rights at Lund University. The authors have participated in the progra

Tourists' place-making performances through music

Traditionally tourists are treated as passive media consumers but this chapter departs from a performance perspective emphasizing tourists’ active role. This chapter deals with how popular music affects tourists’ experiences in destinations by exploring the performance of place-making practices by tourists as they engage with music. The performance perspective is complemented with a ritual perspec

Reciprocal Love as the Foundation for Chiara Lubich’s Theology of Collective Spirituality — Chiara Lubich, one of the most prominent Catholic thinkers of the late 20th century, posits reciprocal love as the foundation for her theology of unity in collective spirituality. Her Spirituality of Unity is followed by a worldwide and cross-denominational Focolare Movement, founded by Lubich in 1943. This

Effects of whole-tree harvesting on soil, soil water and tree growth – A dynamic modelling exercise in four long-term experiments

Whole tree harvesting (WTH) following final felling of productive forests is increasingly promoted as a method to extract biomass for energy purposes. Despite its importance, there is a limited number of experimental studies investigating the impacts of WTH on forest ecosystem sustainability. Modelling studies have previously been carried out to complement and explain empirical observations from f

Predicting vibroacoustic performance of thin-walled lightweight structures during conceptual design

To predict the vibroacoustic performance of complex thin-walled structures, an analysis using a finite element model considering structure–acoustic interaction is often required. The acoustic response of such models can be time-consuming to compute and sensitive to minor design changes. These models can be too computationally intense since fast design optimizations must be performed. Moreover, kno

Quantitative assessment of betainized compounds and associations with dietary and metabolic biomarkers in the randomized study of the healthy Nordic diet (SYSDIET)

Background Recently, a group of betainized compounds have been suggested to play a role in health effects in relation to a whole-grain-rich diet. Objectives The aims of this study were to develop a quantitative mass spectrometric method for selected betainized compounds in human plasma, and to investigate their association with nutrient intake and measures of metabolic health in participants of

Towards a Circular Economy with Environmental Product Policy : Considering dynamics in closing and slowing material loops for lighting products

A Circular Economy (CE) can help to achieve the sustainable development goal of responsible consumption and production. Product policies, in turn, can support CE objectives by promoting reuse of products, recycling of materials, and providing ecodesign incentives for more durable products. This thesis examined the role of product policies in meeting CE objectives in the EU, with specific focus on

Firm survival in complex value chains and global innovation systems : Evidence from solar photovoltaics

Economic globalization and the modularization of value chains increasingly challenge long-held conceptual models explaining the spatial evolution of industries. This paper seeks to re-interpret early industry life cycle dynamics by disintegrating an industry's value chain into upstream, core and downstream parts and characterizing each part according to its underlying global innovation system (GIS

Global inorganic nitrogen dry deposition inferred from ground- and space-based measurements

Atmospheric nitrogen (N) dry deposition is an important component in total N deposition. However, uncertainty exists in the assessment of global dry deposition. Here, we develop empirical models for estimating ground N concentrations using NO 2 satellite measurements from the Ozone Monitoring Instrument (OMI) and ground measurements from 555 monitoring sites. Global patterns and trends in the flux
