This Letter describes a model-agnostic search for pairs of jets (dijets) produced by resonant and non-resonant phenomena beyond the Standard Model in 3.6 fb−1 of proton–proton collisions with a centre-of-mass energy of s=13 TeV recorded by the ATLAS detector at the Large Hadron Collider. The distribution of the invariant mass of the two leading jets is examined for local excesses above a data-deri
The alternating between dry and wet seasons and the consecutive microbial responses to soil water content in semiarid ecosystems has significant consequences on nitrogen exchanges with the atmosphere. Three field campaigns were carried out in a semi arid sahelian rangeland in Dahra (Ferlo, Senegal), two at the beginning of the wet season in July 2012 and July 2013, and the third one in November 20
Klimatförändringarna kommer att påverka ekosystem och samhällen över hela världen. Det är ett problem som kräver drastiska och omedelbara förändringar av vårt sätt att leva och av våra samhällsstrukturer, och därmed politiskt engagemang av aldrig tidigare skådat slag. Under de senaste 30 åren, sedan bildandet av Förenta Nationernas ramkonvention om klimatförändringar (Klimatkonventionen; UNFCCC) åThe rise of climate change as an issue of global concern has rested on scientific representation and understanding of the causes and impacts of, and responses to climatic change. The Intergovernmental Panel on Climate Change (IPCC), in particular, has been central to how climate change has become known as a global political problem. This thesis aims to critically examine the production, negotiatio
Purpose – The study aims to investigate the effects of a remote energy management service to the energy consumption of retail buildings. The study focuses on analysing the changes in energy consumption after the implementation of a facility service concept where building processes are optimized with a remote energy management system. The paper seeks to demonstrate that remotely operated building m
The topic dealt with in this thesis is whether, as Wieder and Kaplan (1969) suggest, the personality of drug addicts is related to their particular drug of choice. The subjects were 128 heavy drug addicts, 37 women and 91 men, each of them selected for the fact of there being one basic drug he/she abused. The drug of choice was either heroin (30 women, 52 men), amphetamine (7 women, 32 men) or can
La2MgNi9-related alloys are superior metal hydride battery anodes as compared to the commercial AB5 alloys. Nd-substituted La2-yNdyMgNi9 intermetallics are of particular interest because of increased diffusion rate of hydrogen and thus improved performance at high discharge currents. The present work presents in operando characterization of the LaNdMgNi9 intermetallic as anode for the nickel metal
In rodent models of Parkinson disease in which transplants of dissociated rodent and human embryonic mesencephalic tissue, rich in dopamine neurons, have been studied, only 5-20% of the dopamine neurons survive the implantation procedure. We have investigated the effects of inhibiting free radical generation with two lazaroids, U-74389G and U-83836E, on the survival of embryonic rat dopamine neuro
To obtain a global overview of how mitochondria respond to stress, we aimed to define the plant mitochondrial stress response (MSR). By combining a set of 1196 Arabidopsis thaliana genes that putatively encode mitochondrial proteins with 16 microarray experiments on stress-related conditions, 45 nuclear encoded genes were defined as widely stress-responsive. Using green fluorescent protein (GFP) f
Abstract Hydrogen embrittlement is a degradation process of mechanical/tribological properties (toughness, wear etc.) of mating steel surfaces. This is caused by the presence and interaction of hydrogen with applied stresses. Therefore, it is important to quantify the hydrogen content which could be dissolved under applied stresses in steel. Water contamination of lubricants is often considered as
Background: Drug therapy in primary care is a challenge for general practitioners (GPs) and the prescribing decision is influenced by several factors. GPs obtain drug information in different ways, from evidence-based sources, their own or others? experiences, or interactions with opinion makers, patients or colleagues. The need for objective drug information sources instead of drug industry-provi
Most of the experiments related to quantum information applications, involving rare-earth doped inorganic crystals, are performed on yttrium orthosilicate single crystals. The work presented here is motivated by the search of new compounds which can be used in the field of quantum computing and/or quantum storage. Relaxation times and hyperfine structure of the H-3(4)(0)-> D-1(2)(0) transition in
Popular Abstract in Swedish Ett nytt betygssystem infördes i grundskolan i Sverige 1995. Det tidigare relativa eller normrelaterade systemet ersattes av ett kriterierelaterat, benämnt det mål- och kunskapsrelaterade betygssystemet. Övergången till kriterierelaterade bedömningsprinciper ställer nya och andra krav på lärare. I denna studie undersöks lärares sätt att erfara betygssystemet och dess tiThis thesis reports results from a study that focuses on how teachers experience the criterion-referenced grading system and how they say they use it in their professional work. The empirical study was carried out as semi-structured audiotaped interviews with thirty qualified teachers, in the subjects English, Maths and Swedish. The outcome of the qualitative analysis consists of four parts. In th
Abstract in Uncoded languages Praegune kaitsejalatsite testimise standard (EN 344) kontrollib soojapidavuslikke omadusi vaid jalatsi ühes punktis mõõtes temperatuuri muutust. Meetod, mis kasutab termilist jala mudelit võimaldab mõõta jalatsi soojaisolatsiooni üheaegselt erinevates piirkondades ning ühtlasi ka jalatsi kui terviku soojaisolatsiooni. Selle uurimuse käigus on soojendatava jala meetodiPresent standard on safety footwear (EN 344) checks the insulation only at one point in the shoes by means of measuring the temperature change. A method that uses thermal foot model allows to measure footwear insulation simultaneously at various locations and for whole footwear as total. In the cause of the present research the method of heated foot model has been developed further. Now it is poss
Background: Clearance of tissue granulocytes is central to the resolution of airway inflammation. To date the focus has been on apoptotic mechanisms of cell removal and little attention has been given to alternative processes. The present study explores transepithelial migration as a mechanism of cell clearance. Method: Guinea pig tracheobronchial airways where eosinophils are constitutively pres
In polyandrous insects, postcopulatory sexual selection is a pervasive evolutionary force favouring male and female traits that allow control of offspring paternity. Males may influence paternity through adaptations for sperm competition, and females through adaptations facilitating cryptic female choice. Yet, the mechanisms are often complex, involving behaviour, physiology or morphology, and the
Following the development of large-scale use of biomass energy in the EU, international biofuel trade is a plausible scenario and something that is already taking place in Northern Europe. This paper focuses on Swedish biofuel imports, both direct and indirect imports, the latter which derive from the fact that part of the imported pulpwood and timber end up as fuel. The objective is to describe t
Multifunctional, light-weight, responsive materials show promise in a range of applications including soft robotics, therapeutic delivery, advanced diagnostics and charge storage. This paper presents a novel, scalable, efficient and sustainable approach for the preparation of cellulose nanofibril-based aerogels via a facile ice-templating, solvent exchange and air-drying procedure, which could rep
Measurements of four-lepton differential and integrated fiducial cross-sections in events with two same-flavour, opposite-charge electron or muon pairs are presented. The data correspond to 139 fb−1 of s = 13 TeV proton-proton collisions, collected by the ATLAS detector during Run 2 of the Large Hadron Collider (2015–2018). The final state has contributions from a number of interesting Standard Mo
