District heating is a common means of space and hot water heating in Sweden. However, the demand for heating is not the same at all times. On a yearly basis more heat is required during winter, while next to none is needed in summer. Since the demand for heat load varies throughout the year, when trying to predict it, using a model that changes with the seasons can give a more accurate prediction.
Cooked ham is a particularly popular cured meat product. Nonetheless, meat consumption constitutes a controversial issue, as researchers correlate red and cured meat with the development of colorectal cancer. One of the main compounds of the cured cooked ham is nitrite. Although, its residual amount in products is considered as responsible for the formation of N-nitrosamines and the provocation of
As CO2 builds up in the atmosphere causing global climate change (IPCC, 2022) trees have become an international symbol of combatting this, and for good reason. Trees take up CO2 which as a result combats these changes, and when these trees are cut down fewer individuals remain to take up the CO2 that we humans emit (Chapin et al., 2011). This means that clear-cut areas don’t act as the carbon sin
Syftet med denna studie är att undersöka hur musiker som har drabbats av tinnitus eller ljudöverkänslighet hanterar sitt yrke. Underlaget för studien består av fem stycken intervjuer med aktiva musiker inom klassisk musik, jazz och rock/blues som drabbats av tinnitus och/eller ljudöverkänslighet. Studiens resultat visar på följande åtgärder och är kategoriserade efter dessa: sjukskrivning/längre uTitle: A life in crash and bang - research about how musicians with tinnitus cope with their profession The purpose of this study is to investigate how musicians who have been affected by tinnitus or sound sensitivity deal with their profession. The material of this study consists of five interviews with professional musicians active within the classical music sphere as well as within jazz and roc
Child molesters are possibly the most despised and feared of all criminals. Since children are some of the most vulnerable members of our society, sex crimes against children provoke a great deal of anxiety and are seen as particularly distressing. In recent years, the debate whether Sweden should introduce additional punishment and treatment options that are specifically designed to deal with sex
This paper examines how different variables affect the ticket price, using three different hypotheses. The first is how price is affected by time between ticket purchase and retirement. The second hypothesis tests the price changes in relation to the distance between destinations and the third hypothesis is testing whether competition has any role in the various cities. The various hypotheses are
The main purpose of this essay was to find out what motivates immigrants to start their own business. We decided to study the local immigrant-owned pizzarestaurants in Halmstad, Sweden. We choose to conduct a questionnaire and a couple of interviews, which was a complementary to extend our understanding. We wanted to get their view of motivations behind the choice to run their own business. We als
Shortly after the start of the transition from planned to market economy in Central and Eastern Europe and the former Soviet Union, an overall drastic fertility decrease began in all the countries of this region. This thesis focuses on the theoretical and empirical connection between transition and fertility. With the use of Gary Becker´s New Home Economics as a theoretical framework, fertility d
The focus in this thesis has been active power from small scale solar production and what possible impacts an increased proportion of small scale production can have, in a larger context, during short circuit (SC) faults in the grid. The main research question prompting this work was whether active power from small scale solar pro- duction can help support voltages during SC faults, and meet LVRT-
Drug delivery with lipid nanoparticles, especially sponge phase lipid nanoparticles (LNP), has been well studied because of its ability for drug encapsulation and transferring the drug through the cell membrane. The sponge phase LNP formulation could be affected by the molecular structure of the lipid, the temperature, pH, dilution, the buffer, and the addition of a stabiliser. This project aimed
The European Union implements the Environmental Noise Directive (END), which offers a framework for evaluating and assessing environmental noise. All EU members are required to create strategic noise maps to inform the public about noise pollution and its effects. This study followed these directives and guidelines to collect the required data and employed the NORD2000 model to simulate traffic no
Detailed atomic structures are key to understand and evaluate catalytic activity, ligand binding affinities and many other properties. Neutron crystallography is a popular method for deriving structures of proteins. Unfortunately, the experimental data is typically not enough to settle the exact position of all atoms. Therefore, empirical restraints are employed to ensure that the final structures
The year of 2020 was marked with an unprecedented outbreak of Covid-19 virus and a global pandemic. Not all businesses across various industries have been equally affected. This thesis investigated the difference in return of industries with dissimilar exposure to the Covid-19 pandemic under the lockdown and social distance intervention, and how this difference has evolved during 2020. We found ev
Background: Pharmaco-mechanical thrombolysis (PMT) has emerged as a treatment option in patients with acute lower limb ischemia (ALI), especially Rutherford IIb (motor deficit) for rapid revascularization, but supportive data is scarce. The aim of the present study was to compare the effects of thrombolysis, complications, and outcomes of PMT first versus catheter-directed thrombolysis (CDT) first
Above-ground biomass (AGB) is considered an essential climate variable that underpins our knowledge and information about the role of forests in mitigating climate change. The availability of satellite-based AGB and AGB change (ΔAGB) products has increased in recent years. Here we assessed the past decade net ΔAGB derived from four recent global multi-date AGB maps: ESA-CCI maps, WRI-Flux model, J
Aim: Our aim was to investigate in a large population-based cohort study whether increased arterial stiffness and subclinical atherosclerosis in the coronary arteries differ at different stages of dysglycaemia. Methods: Data were obtained from SCAPIS, a population-based cohort of participants 50–64 years. The study population of 9379 participants was categorised according to glycaemic status: norm
Light cues elicit strong responses from nearly all forms of life, perhaps most notably as circadian rhythms entrained by periods of daylight and darkness. Atypical periods of darkness, like solar eclipses, provide rare opportunities to study biological responses to light cues. By using a continental scale radar network, we investigated responses of flying animals to the total solar eclipse of 21 A
Two MgRE (RE = Ce, Nd) alloys with ultrafine-grain (UFG) microstructures were prepared by high-pressure torsion (HPT) at room temperature. The in-depth distribution of defects was characterized by Doppler broadening –variable energy positron annihilation spectroscopy (DB-VEPAS). The characteristic S parameter increases in bulk after HPT processing relative to an as-received sample and shows a rela
