We present a novel event-generation framework for the efficient simulation of vector boson plus multijet backgrounds at the high-luminosity LHC and at possible future hadron colliders. Message passing interface parallelization of parton-level and particle-level event generation and storage of parton-level event information using the HDF5 data format allow us to obtain leading-order merged Monte Ca
Ice-marginal moraines are widely used as indicators of palaeoclimate in mountainous regions, yet the genetic processes of their formation remain incompletely understood. Here, we present new data on the geomorphology and sedimentology of annually formed moraine ridges in the foreland of Gornergletscher, Switzerland, with the aim of reconstructing the processes of their formation, assessing their p
This thesis introduces two new incommensurate alloys. AuIn shows variable amounts of modulation, depending on the measurement temperature. At 400°C the diffraction pattern shows diffuse scattering and a thallium iodide type Cmcm space group. The diffuse scattering condenses into first order satellites on cooling to 300°C and the space group transforms to the incommensurate C-1(α, β, γ)0. I.e. the
The stable carbon isotope ratio (δ13C) is a key tool in tracing the source of carbon within and across ecosystems. In isotope mixing models dissolved organic carbon (DOC) from terrestrial sources is often assigned a fixed δ13C of roughly -28‰ to -27‰ in C3 plant-dominated areas. However, the claim of a uniform δ13C distribution for terrestrial DOC sources of different reactivity has seldom been te
Eastern boundary upwelling systems (EBUS) are among the most productive marine ecosystems on Earth. The production of organic material is fueled by upwelling of nutrient-rich deep waters and high incident light at the sea surface. However, biotic and abiotic factors can modify surface production and related biogeochemical processes. Determining these factors is important because EBUS are considere
Background: Apnea of prematurity is a common problem in preterm infants that may have significant consequences on their development. Methylxanthines (aminophylline, theophylline, and caffeine) are effective in the treatment of apnea of prematurity. Doxapram is used as a respiratory stimulant in cases refractory to the methylxanthine treatment. Objectives: To evaluate the benefits and harms of doxa
Lignin is one of the three predominant biopolymers that make up plants together with cellulose and hemicellulose, and it is the only plant component that is based on aromatic units. The industrial kraft pulping process generates large amounts of lignin, which is currently used to generate heat for the process. The subject of this thesis is the valorization of kraft lignin into valuable chemicals.
Fatigue safety verification of existing bridges that uses ''re-calculation'' based on codes, usually results in insufficient fatigue safety, triggering invasive interventions. Instead of “re-calculation”, Structural Health Monitoring (SHM) should be used for the assessment of the existing bridges. Monitoring systems provide data that can reduce uncertainties associated with the fatigue loading pro
Ett av Sveriges klimat- och energipolitiska mål avser effektivare energianvändning. Ett sätt att uppnå målet är genom kravställning på energihushållning vid renovering av byggnader. I de fall då det med hänsyn till byggnadens kultur- och arkitektoniska värde inte går att tillämpa beprövade metoder får andra alternativa metoder sökas. En sådan annan alternativ metod är en dubbelskalfasad och innebäOne of Sweden's political objective is to increase energy efficiency. One way to achieve the objective is by making demands on the use of energy after a building has been renovated. Regarding the building's cultural and architectural values there are cases where it is not possible to apply proven methods to meet the demands, and other alternative methods must be sought. Such an alternative
This thesis report treats my individual project “The Filter”, a result from the Bachelor Studio Contemporary Architecture at the faculty of Engineering at Lund University. The report describes my design and concept process. I Investigated how to design a Filter that demonstrates the natural cleaning process, and how to design the other parts of the naturrum. The report displays how the design deci
Inom dagens arbetsmarknad har det blivit allt svårare för organisationer att attrahera och behålla värdefulla och kompetenta medarbetare. På grund av detta har organisationer börjat fokusera på sin employer branding för att kommunicera vad de erbjuder arbetstagare och anställda. Samtidigt har en ny generation börjat komma in på arbetsmarknaden. Med detta i åtanke är syftet med denna studie att bidWithin today's labor market it has become increasingly difficult for organizations to attract and keep competent and valuable employees. Because of this organizations have started to focus on their employer branding in order to communicate what they offer employees. Simultaneously a new generation has started to enter the labor market. With this in mind the aim of this study is to contribute t
In the last twenty-five years, the influence of climate change over the lives of the world’s citizens has become a central topic of discussion within multilateral organisations such as the United Nations. The topic of policy and decision- making capacity, as well as representation of developing nations such as Small Island Developing States (SIDS) is also constant. This research is conducted as a
Den svenska bostadsmarknaden präglas av en bostadsbristsituation, en situation som enligt Boverket förvärrats av omvärldshändelser som covid-19 och kriget i Ukraina. Det är i denna kontext intressant att undersöka orsaken och implikationerna av observerade skillnader i belåningsgrad och marknadsvärdestillväxt mellan kommunala bostadsbolag och privata fastighetsbolag. Syftet med arbetet är att unIn Sweden it has for many years been the common understanding that there is a shortage of housing on the housing market, a situation that according to Boverket has been further worsened by recent world events such as the Covid-19 pandemic and the Russian war of aggression against Ukraine. In this context it was interesting to study the cause of and implications of observed differences in the grow
Vid alla rättsliga förfaranden som rör barn ska principen om barnets bästa beaktas. Principen är väl omdiskuterad och det finns ingen universell fastslagen definition. Internationella adoptioner är en av processerna som ska utgå från principen. Detta stadgas i såväl nationell lagstiftning som internationella konventioner. Rådande diskurs om internationella adoptioner har under de senaste decennierIn every legal process regarding children, the principle of best interests of the child must be considered. The principle is well discussed and does not have a universal determined definition. Intercountry adoption is one of the proceedings that must consider the principle. This is stipulated in both national and international law. During the last decades, the prevailing view on intercountry adopt
The wood pulp industry has been around for a long time, but new higher quality pulp require more advanced solutions to old processes. One of these processes is the peroxide (PO) bleaching process, which is the last of a whole chain of bleaching processes at the Mörrum pulp processing plant. The aim of this thesis was to develop and study a model for the peroxide pulp bleaching process, and thereaf
Enligt svensk rätt har den misstänkte inte någon möjlighet att bli betraktad som slutligt avförd eller friad från en brottsmisstanke innan åklagaren har väckt åtal. Till dess är brottmålsprocessen i princip helt inkvisitorisk, vilket ställer höga krav på rättssäkerheten. Avsikten med uppsatsen är att genom rättsdogmatisk metod granska de rättsliga medel som åklagaren har till sitt förfogande för aA suspect has no opportunity by Swedish law to be considered as finally crossed out or acquitted from a suspicion of crime before prosecution. Until prosecution the proceedings are in essence totally inquisitorial, which requires high legal security. This thesis aims to, by a legal dogmatic method, examine the prosecutor’s legal instruments of terminating an investigation. Furthermore, these legal
Matsvinn är ett problem med miljömässiga, ekonomiska och sociala konsekvenser. Nära en tredjedel av maten som produceras i världen idag kastas eller förstörs, något som är ohållbart av en mängd anledningar. Ett forskningsprojekt som drivs för att åtgärda detta är DynahMat-projektet på Lunds Universitet. DynahMat föreslår användandet av temperaturindikatorer och andra sensorer för att beräkna en prFood waste is a problem with environmental, economic and societal aspects. Up to a third of global food production is wasted every year, something that is unsustainable in many ways. Much research is currently being done to alleviate the problem. The DynahMat project at Lund University proposes using temperature indicators and sensor technology to improve food supply chains and provide a more accu
