One of the first results in classical computability theory was establishing the undecidability of the halting problem. In this thesis we will prove an even stronger version in the internal logic of the effective topos; more precisely in its full subcategory \(Mod(\mathcal{K}_1)\) of modest sets internal to assemblies \(Ass(\mathcal{K}_1)\). We will do this by proving that the diagonal halting set
Syftet med uppsatsen är att undersöka vilka likheter och skillnader det finns i de styrdokument som reglerar utbildningen för nyanlända elever i Sverige och i den autonoma regionen Andalusien i Spanien. Det svenska styrdokumentet utgörs av de allmänna råd som Skolverket publicerade 2016 och det spanska dokumentet är en lagtext som reglerar undervisningen för nyanlända från 2007. Studien är en komp
Adipic acid (AA) has been a valuable industry chemical over the last century, whose production process carbon footprint resides far away from today’s environment-friendly ideals. Therefore, a biological approach for adipic acid production under mild conditions has been studied in this thesis. Wild-type strains of Gluconobacter oxydans have been cultivated to obtain resting cells that were used for
With the rise in urbanization and cities fulfilling sustainability challenges, companies across the globe are moving towards circularity. One approach adopted towards circularity is of reverse logistics where companies take back EOL/EOU products. In the furniture industry, this approach towards circularity is coupled with consumers being asked to transport the EOL/EOU furniture to second-hand/ret
Om en part har tillräckligt starka misstankar om att motparten inte kommer att fullfölja sina avtalsförpliktelser och begå ett avtalsbrott vill den drabbade parten naturligtvis skydda sig från att drabbas av brottet. Den drabbade parten kan skydda sig mot ett s.k. befarat avtalsbrott genom att utöva stoppningsrätten eller hävningsrätten. Stoppningsrätten regleras i 61 § KöpL och innebär att den drIf a party suspects the other party will not fulfill a substantial part of his obligations according to the contract this would mean that they are breaching the terms of their contract. This means that the affected party can protect itself against a breach of contract, “anticipatory breach”, under contractual law by exercising the rights of suspension or cancellation (stoppningsrätten or hävningsr
Although most individuals consider gambling to be an innocent and fun activity, when it develops into problem gambling (PG), it can have detrimental outcomes to one’s life, such as over-indebtedness. This study explores the role of maladaptive personality traits and gender in both PG and over-indebtedness, in an online sample of 1479 adult gamblers in Sweden. Participants were administered the Pro
Respiratory tract infections (RTIs) pose severe threats to global health. The microbial profile of the respiratory tract largely impacts their ecological niche. Epidemiological studies indicate that nasopharyngeal colonization of commensals like Corynebacterium spp is associated with reduced rates of RTIs, but the underlying mechanisms are undefined. Besides, most pathogens like Streptococcus pneu
The goal of this thesis was to, from several randomly selected patients with diagnosed malignant and benign tumors, record optimal lambdas and respective Renyi entropies for each lambda, run a basic statistical analysis of the results and see if there is any significant difference between lambdas/Renyi entropies of malignant and benign lesions.\\ The results showed no significant difference.\\ The
This paper legally tests federated learning as a machine learning technique, which guarantees a high level of privacy. This paper provides answers to all legal aspects of this technical development as the first legal paper in this area, while challenging vague GDPR requirements. This method showed its supremacy over conventional anonymization techniques and other machine learning techniques. It mi
Privata sjukvårdsförsäkringar har ökat de senaste åren i Sverige. Detta trots att Sverige har en offentlig vård som ska ge en vård på lika villkor för hela befolkningen. Vilka faktorer kan påverkar en sådan ökningen av privata sjukvårdsförsäkringar och eventuella underliggande anledningen finns det till att anskaffa en sådan försäkring. Studien syftar till att diskutera motiven till detta köp med
Differentiated instruction is a widely known approach used in different educational settings, especially in diverse classrooms. Teachers are expected to be able to meet the need of all learners and differentiate instructional parameters such as content, process and product accordingly. While previous research has shown that a successful implementation of the concept is beneficial for the students,
Buildings are a are a major consumer of energy in urban areas. The use of solar energy in buildings can help reduce CO2 emitting energy consumption in these urban areas. One way to use solar energy is through passive solar energy systems. Passive solar energy systems allow a building to use daylight as an energy source. The use of daylight as passive solar energy in Sweden could reduce the energy
Due to the serious problem of greenhouse gas emissions in our atmosphere driving global warming, the need for sustainable initiatives has become an imperative for companies which leads to the necessity of operating sustainably. However, to avoid taking a weak approach to sustainability, it is imperative for companies to carry out a transition involving all three dimensions (environmental, economic
Denna avhandling är resultatet av en kvalitativ studie som undersöker identitetsskapande och upprätthållande av sociala normer på sociala medieplattformen LinkedIn. Metodvalet för att genomföra detta var den kvalitativa och etnografiska undersökningsmetoden nätnografi. En digital frågelista konstruerades på enkätplattformen Survio, med öppna frågor och besvarades av respondenter som i någon mån är
Idag präglas världen av teknikutvecklingen som både anses vara en fördel och en nackdel. För den kriminella världen och organiserade ekonomiska brottsligheten är digitaliseringen en fördel. Moderna tekniska lösningar gör det enklare för gärningsmännen att begå brott, såsom penningtvätt vilket regleras i penningtvättslagen (2017:630). Penningtvättsbrott förekommer både nationellt som internationellToday, the world is characterized by technological development that could be considered both as an advantage and a disadvantage. For the criminal world and organized economic crime, digitalization is seen as an advantage. The modern technical solutions make it easier for the perpetrators to commit crimes, such as money laundering which is regulated in the Money Laundering Act (2017:630). Money lau
Denna kvalitativa intervjustudies syfte är att undersöka hur och om organisationer/företag motverkar diskriminering under rekryteringsprocessen. Detta gjordes genom att intervjua nio enskilda rekryterare inom, främst, konsult- och bemanningsbranschen. Genom intervjuerna fick jag ta del av deras rekryteringsprocesser och hur de arbetar med diskriminering Intervjuerna har analyserat genom en tolknin
Begreppet lojalitetsplikt har sitt ursprung i den romerska rätten och har sedan dess spridits till stora delar av västvärlden. Lojalitetsplikten brukar definieras som en plikt att iaktta, eller att tillvarata, motpartens intressen. Lojalitetsplikten gäller som en allmän rättsprincip även om dess betydelse i avtalsförhållanden länge var ifrågasatt. Under senare tid har debatten om vad den innebär fThe contractual principle of loyalty origins from Roman law and has since then spread to most parts of the western world. The general definition of the principle is that a party has a duty to consider the interests of the counterpart. Nowadays the principle of loyalty has become a general principle of law, even if its status in contractual relations was questioned for a long period of time. It ha
