A search for heavy resonances decaying into a pair of Z bosons leading to ℓ+ℓ-ℓ+ℓ- and ℓ+ℓ- final states, where ℓ stands for either an electron or a muon, is presented. The search uses proton–proton collision data at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 36.1 fb - 1 collected with the ATLAS detector during 2015 and 2016 at the Large Hadron Collider. Differe
MAX IV-laboratoriet är en anläggning med syfte att producerasynkrotronljus till forskning. När laddade partiklar accelereras skickar de ut energi i form av strålning kallad synkrotronljus. Synkrotronljus är intensivt ljus med många olika våglängder och är därför väldigt användbart för att studera strukturer och processer inom många olika fält såsom materialforskning, medicin, geologi och arkeologiThe MAX IV facility includes two storage rings, operated at 1.5 and 3 GeV energy, for the purpose of producing high-brilliance synchrotron radiation for users. The 1.5 GeV ring replaces the previous MAX II and MAX III storage rings as a source of UV and soft X-rays, whereas the 3 GeV ring is optimized for hard X-rays. The 3 GeV ring is the first of a new generation of synchrotron light storagering
We present a new model for building up complete exclusive hadronic final states in high energy nucleus collisions. It is a direct extrapolation of high energy pp collisions (as described by Pythia), and thus bridges a large part of the existing gap between heavy ion and high energy physics phenomenology. The model is inspired by the old Fritiof model and the notion of wounded nucleons. Two essenti
This paper examines the impact of climate variability on inter-municipal household migration in the Guatemalan Dry Corridor (GDC) between 2013 and 2018. Monthly georeferenced precipitation and temperature data are used to build a climate shock variable that captures prolonged exposure to droughts and heatwaves at the municipality level. The data is used to understand if the occurrence of a shock a
The accurate diagnosis of malaria is crucial for ensuring an effective treatment and combating the developing drug resistance of the parasite. The standard diagnostic method, consisting of light microscopy in combination with Giemsa-staining, requires manual examination through a trained clinician. This is time-consuming and prone to human error. While emerging diagnostic innovations can overcome
Oligonucleotides are short fragments of RNA or DNA that can act as active pharmaceutical ingredients (API) in medicines used to target a wide range of diseases, with further applications continuously emerging. Solid Phase Oligonucleotide Synthesis (SPOS) remains the dominant platform for oligonucleotide production. However, SPOS is characterized by high reagent consumption and a poor sustainabilit
This thesis explores arguments and styles of argumentation in favour of Scotland gaining independence and rejoining the European Union in the aftermath of the United Kingdom leaving the EU in 2020. Since a majority of Scots did not support Brexit, it has provided Scottish independence supporters with a unique opportunity to bolster their arguments in the political debate. The thesis is built on a
Cow horn has been a craftig material in Europe for 1000s of years. Yet, in the last 100 years the material has disappeard from our pool of commonly used materials. Today it is mostly used for dogfood and gelatine. I believe that horn could again become a commonly used crafting material, especially for modern and sustainable products. Among my many visions for horn, I see it as a beautiful, natu
Italy is using drones to monitor migrants crossing the Mediterranean Sea. This is partially done through a contract with Leonardo S.p.A – one of the largest arms traders in the world – under which the company undertakes to operate drones in the area on behalf of the state. Meanwhile, Italy has withdrawn its naval assets and is hindering non-governmental organisations from carrying out search-and-r
Correct operation of real-time systems (RTS) is defined as producing correct results within given time constraints (deadlines). As RTS are becoming more susceptible to soft errors, employing fault-tolerant techniques is crucial. Rollback Recovery with Checkpointing (RRC) is an efficient fault-tolerant technique. However, RRC introduces a time overhead which depends on the number of checkpoints. Th
The complexity status of the minimum r-star cover problem for orthogonal polygons had been open for many years, until 2004 when Ch. Worman and J. M. Keil proved it to be polynomially tractable (Polygon decomposition and the orthogonal art gallery problem, IJCGA 17(2) (2007), 105-138). However, since their algorithm has (O) over tilde (n(17))-time complexity, where (O) over tilde (.) hides a polylo
In the search for the fully aligned 27(-) state in Nd-140 predicted by cranked Nilsson-Strutinsky calculations, new close-to-spherical high-spin states have been discovered. Both the close-to-spherical and the triaxial calculated states are in good agreement with the experimental results, supporting the existence of shape coexistence up to very high spins. Shell-model calculations using a newly de
The last decades the modern sporthorse have changed a lot, both physically and in temperament. Horses have gotten more athletic, sensitive and faster. Selective breeding, new science findings and more competition, in combination with a role change from workhorse to sporthorse have made this change possible. The idea to investigate and develop horse equipment was initialised during meetings with th

Den offentliga sektorn står inför utmaningar när det kommer till digitalisering och medborgare har höga förväntningar på att den offentliga sektorn ska vara effektiv och erbjuda högkvalitativ service. År 2018 tilldelades den portugisiska kommunen Cascais ett pris från organisationen World Summit Awards för sin digitala plattform City Points Cascais inom kategorin, Digital Innovation in Government The public sector is facing challenges related to digitalization. Modern citizens have expectations that the public sector should be more efficient and provide quality services. In the year of 2018, the municipality of Cascais, Portugal, was awarded the best platform in the category Digital Innovation in Government and Citizen Engagement by the World Summit Awards. The platform is called City Poin
For most people getting a stroller is an obvious thing to do when having a baby. It’s mainly used for transportation of the baby but has other functions as well. For example, it is used as a storage, serves as a shopping bag for groceries and makes a perfect bed for a baby nap. Using a stroller should be easy and safe, but when it’s getting dark outside it can be hard to see the road ahead and fin
To control an accelerating proton beam that travels close to the speed of light, a large number of beam diagnostic instruments are needed. One of the instruments that will be used at the accelerator of the European Spallation Source is a Non-invasive Profile Monitor (NPM). Once installed, this system will measure the transverse beam profile by imaging the fluorescent gas induced by the accelerated
This report uses a relational theory of risk within which risk is understood as a relationship between a risk object and an object at risk where the risk object threatens the value embedded in the object at risk. A case study of risk management in railway planning examined through a relational understanding of risk demonstrates how riskwork is conditioned by what is valued, how, and by whom. The r
Background: Vietnam introduced the Health Care Fund for the Poor in 2002 to increase access to health care and reduce the financial burden of health expenditure faced by the poor and ethnic minorities. It is often argued that effects of financing reforms take a long time to materialize. This study evaluates the short-term impact of the program to determine if pro-poor financing programs can achiev
