Inom partikelfysik, går de teoretiska och experimentella aspekterna hand i hand. För att förstå hur partiklar växelverkar med varandra och kunna förstå experimentella resultat, behövs en teoretisk modell av interaktionerna. Feynmandiagram erbjuder exakt detta, ett verktyg för att simpelt visualisera partikelprocesser. Med Feynmandiagram är det möjligt att förstå vilka processer som är möjliga och This thesis explores the simplifications the chirality-flow formalism brings the calculations of scattering amplitudes in massless QED. We explain Feynman diagrams and chirality- flow diagrams to emphasize how the calculations of scattering amplitudes differ. It is studied how applying the chirality-flow formalism simplifies the calculations. The work focuses on calculations with and without exter

Filmturism och dess påverkan på destinationer är ett komplext fenomen. Användandet av storytelling på destinationer som är influerade av filmturism har visat på tydliga fördelar för att turister ska återvända till platsen. Storytelling är tillsammans med filmturism utgångspunkten för denna kandidatuppsats. Storytelling inom filmturismsammanhang tillämpas ofta i samband med upplevelser för att belyFilm tourism and its impact on destinations is a complex phenomenon. The use of storytelling on destinations that are influenced by film tourism has shown clear benefits for tourists to return to the place. Storytelling, together with film tourism, is the starting point for this bachelor thesis. Storytelling in the context of film tourism is often applied in the context of experiences to highlight

The Convention on the Rights of the Child was incorporated into Swedish law in 2020 to strengthen children's social rights. Since its incorporation, researchers have investigated how the Convention has affected work with children's rights. There are still knowledge gaps on how to interpret these principles. This study aims to understand how the child's best interests, the child's o

The construction industry has shown a significant interest in timber due to its sustainability, leading to widespread use. However, choosing the ideal material can be challenging due to the varying performance of different types of wood, especially considering its combustible nature. Besides, the joints in the timber structure are considered the weakest part of the structure. The physical separati

Intimate partner violence is a serious societal issue with far-reaching consequences for women's health, safety, and overall life conditions. This study explores how women who have experienced violence in heterosexual relationships describe their journey toward leaving their abusive partners. By analyzing five autobiographical narratives written by Swedish women, the study seeks to uncover emo

Agility has emerged as a strategic ideal across many sectors, especially within financial institutions facing heightened pressure to respond swiftly to technological disruption, regulatory shifts, and market volatility. While commonly positioned as a solution to organizational inertia, agility is often promoted through leadership programs and strategic narratives that assume a shared understanding

När maten blir en risk: Om smittskydd och ansvar inom äldreomsor gen Livsmedelsburna sjukdomar förekommer över hela världen och kan orsaka sjukdom hos alla människor. Äldre människor är i riskgrupp på grund av deras nedsatta immunsvar och längre återhämtningstid. Detta gör att våra äldre drabbas hårdare av sjukdomar än andra. Samtidigt är det en del av vår äldre befolkning som bor på äldreboen

Aims: To assess whether cancer incidence and mortality in chronic obstructive lung diseases were increased in the Swedish polyurethane foam industry cohort, updated with 11 more years of follow up. Methods: The mortality and cancer incidence (1959–98) experienced by a cohort of 4175 male and female employees employed for at least one year in the period 1959–87 at one of nine Swedish polyurethane

Comparisons have revealed large discrepancies among the many methods for measuring soil CO2 efflux indicating the need for an absolute calibration of methods. This study presents a calibration system, constructed to imitate an area of soil, and its application to two different chamber systems for the measurement Of Soil CO2 efflux: one open and one closed dynamic. Air rich in CO2 was allowed to di

Knut Hamsun (1859-1952) is generally regarded as one of the first proponents of modern literature in Scandinavia. The present thesis discusses the author’s breakthrough phase which took place around the year 1890. This was an era when societal modernity became established in the Scandinavian countries, and new and revolutionary ideas and norms appeared concerning society, science, and art. Hamsun

Leuprolide is a gonadotropin-releasing hormone (GnRH) analog which has been shown to reduce symptoms in patients with irritable bowel syndrome (IBS) and chronic intestinal pseudo-obstruction (CIPO). The mechanism is not known, but one hypothesis is through down-modulation of luteinizing hormone (LH) secretion, a hormone whith antagonistic effect on gastrointestinal motility. However, presence of L

Abstract in UndeterminedFaster-than-Nyquist (FTN) signaling is a method of improving bandwidth efficiency by transmitting information beyond Nyquist's orthogonality limit for interference free transmission. Previously have theoretically established that FTN can provide improved bandwidth efficiency. However, this comes at the cost of higher decoding complexity at the receiver. Our work has evaluat

In this article we probe the effect of democratization on the state's administrative capacity. Using time-series cross-section data, we find a curvilinear (J-shaped) relationship between the two traits. The effect of democracy on state capacity is negative at low values of democracy, nonexistent at median values, and strongly positive at high democracy levels. This is confirmed under demanding sta

In this research paper, a result of an internship at Art Dubai 2014, I attempt to deconstruct the notion of Arab contemporary art as a monolithic term. The deconstruction occurs through two case studies that pertain to Arab contemporary art. The first case study, I interview artists from the region and conduct visual analysis of their artwork in an attempt to identify aesthetical aspects that pert

The high amount of information circulating on the Internet and the consequent possibility to monitor this information has sparked a discussion regarding privacy on the Internet. In early 2012, the EU responded to this by presenting a major reform of its data protection legislation. It is the possible source of this reform that has been of interest in this study. With a discourse analysis guided by

In this thesis the influence of strong reflections in rooms is investigated. A strong reflection can have a negative influence on speech or music that is transmitted from the source to the receiver. Impulse responses including different strength of a reflection are modelled using a statistical model. From the impulse response, different parameters describing the strength of the reflection can be c
