När vi tittar ut i universum ser vi bara materia, även fast vi vet att antimateria finns. Enligt teorin borde antimateria, som är precis som vanlig materia fast med motsatt laddning, producerats i lika stora mängder vid Big Bang. Partikelacceleratorn LHC i Schweiz genererar lika mycket materia och antimateria i partikelkollisioner som påminner om de som skedde i samband med Big Bang. Så det skulleThis thesis investigates the properties of a general scale-invariant Two-Higgs-Doublet Model and its phenomenological consequences with focus on the scalar sector. The concept suggests that introducing more CP-violation, both spontaneous and explicit, may make it possible to meet the Sakharov conditions and account for the Universe's baryon asymmetry. We define a modified renormalization schem

Stress coping mechanisms are a well renowned tool to reduce a stressor. Furthermore, life partners play a tremendous role in the life of an entrepreneur, either being supportive or straining. Yet, their influence is underexp

This thesis explores the UTVs (Utility Terrain Vehicle) transition from internal combustion engines to electric drive and how the shift will impact Atlas Copco as an assembly tool manufacturer. Research is conducted based on a mixed-method approach, using both semi-structured interviews with key manufacturers and Atlas Copco sales engineers, as well as a multiple case study at manufacturing plants

With an ever-increasing human ecological footprint, the United Nations Sustainable Development Goals require global collaboration in terms of sustainable business practices to combat global ecological issues. Our study examines the complex relationship between eco-innovation, CO2 emissions, and financial performance using fixed effects panel data regression. While R&D is positively correlated

The bachelor’s thesis research focuses on Robotic Process Automation (RPA). The purpose was to explore the opportunities and challenges of the applications of RPA software in conglomerate organizations from the perspective of RPA practitioners. A qualitative study was conducted where the empirical data were collected through semi-structured interviews with five purposively selected RPA practitione

Syfte Uppsatsens syfte var att undersöka om och i så fall hur sångintervention i klassrummet ger effekter på den språkliga förmågan, närmare bestämt på förståelse och produktion av berättelser, hos elever i årskurs 2. Metod Deltagare i studien var 66 elever i årskurs 2 från två olika skolor, fördelade på två grupper A och B. Sångintervention gavs fyra gånger i veckan i 5 veckor och data samlades iPurpose The aim of this paper was to investigate if and how song intervention in the classroom has an effect on narrative comprehension and production in Primary school students (2nd grade). Method Sixty-six 2nd grade students from two different schools, divided into two groups, A and B, participated. Song intervention was carried out four times a week for five weeks. Data was collected at three t

Begreppet visselblåsare benämner en person som avslöjar missförhållanden i myndigheter, företag eller samhället i övrigt. I arbetslivet är visselblåsning särskilt viktigt eftersom visselblåsaren ofta avslöjar viktig information som allmänheten inte har tillgång till. Trots det har studier visat att arbetstagare som får kännedom om missförhållanden ofta avstår från att slå larm. Regeringen antog EUThe term "whistleblower" refers to an individual who discloses wrongdoing in authorities, companies, or society in general. Whistleblowing holds significant importance in the workplace as it frequently unveils vital information inaccessible to the general public. However, studies have shown that employees who become aware of misconduct frequently choose not to report it. The EU-directive

In recent years, an upsurge of political representatives have embraced a requirement-based approach to naturalization as a means to promote integration. By drawing upon theories from Critical Language Testing, Standard Language Ideology, Critical Discourse Analysis, together with the methodological framework of Norman

Artificial intelligence (AI) within healthcare creates opportunities to save more human lives regarding the prevention and prediction of diseases. This thesis has its main focus on the proposed AI Act and in what way the proposed AI Act promotes innovation and ensures privacy concerning the collection of patient data for the prevention and prediction of diseases. Furthermore, is there a balance be

This thesis examines the loss of social media during incarceration and how incarcerated individuals reflect on the abrupt absence of social media in their lives. Based upon eight interviews with previously incarcerated individuals, this thesis studies the emotional process incarcerated people go through when doing identity work. Building upon Erving Goffman’s framework of identity and self-present

The aim of this study is to examine professionals´ attitudes toward intellectually disabled people wanting to become parents in housing with special services for adults. The study also highlights how the professional´s response to such situations and what difficulties it may lead to. Nine individual interviews have been carried out with residential staff, which means that the study was based on a

Dark matter accounts for about 85% of all matter in the Universe, yet its particle nature remains unknown. The Light Dark Matter eXperiment (LDMX) is a proposed fixed-target missing-momentum experiment that intends to probe the predominantly experimentally uncharted MeV-GeV mass range for "light dark matter". A significant challenge for LDMX is to efficiently veto rare photo-nuclear back

The corona pandemic has mainly affected health conditions and mortality, but has also contributed to economic costs. In this paper, I analyzed the consequences of restrictions on excess mortality and macroeconomics as well as the impact of economic policy measures on the economy. Based on data from European OECD countries in 2010-2022, I found evidence that restrictions do not reduce excess mortal

The study is compiled into a composite index for assessing the climate vulnerability of African nations. By employing a multidimensional approach, the index comprises nine distinctive hazards to examine a country’s sensitivity to climate change. These hazards are divided into three categories; acute physical hazards, chronic physical hazards and systemic hazards. This index structure is based on t
