Supramolekulär kemi är ett fält inom kemi där samlingar av molekyler som hålls ihop av olika ickebindande interaktioner mellan molekylerna studeras. Dessa bindingar kan ses som två legobitar som sätts ihop, där legobitarna är molekylerna och det ickebindinade interaktionerna är passformen som håller dem på plats. Legobitarna kan tas isär med mindre kraft än vad det krävs för att dela en bit lego. Hydrogen bonding based self-assembly is prevalent throughout nature dictating the folding of proteins and DNA. Hydrogen bonding has been utilized for self-assembly of small monomers into aggregates of varying size and shape. Potential applications of these aggregates could be creation of ion channels, formation of inclusion complex for delivery of drugs or capture of hazardous material in water su

The existence and staffing of reference desks in academic libraries has been a topic of debate for at least 30 years. As digital library services have grown in significance, some argue that the physical desk no longer serves the needs and wishes of patrons. The use of the academic librarian behind the desk has also been questioned – studies have shown a gain in efficiency when letting student work

Samhället genomgår en konstant digital omvandling och utveckling. Detta gör att arbetstagare och deras arbete är i konstant förändring. Denna process har accelererat senaste åren. Samhällets kapacitet att svara på yttre omständigheter kom att testas under Covid-19 Pandemin. Denna uppsats undersöker hur det digitala skiftet under i början av, samt efter pandemin påverkat och mottagits av arbetstaga

Planning safe paths in the presence of uncertainty is considered a central challenge in enabling robots to successfully navigate in real-world environments. Assumptions about Gaussian uncertainty are rarely justifiable based on real data and can lead to serious miscalculations of risk. Lately, it has become increasingly common to consider distributionally robust uncertainty, where the exact distri

Utvecklingen av AI-teknologier har gått snabbt de senaste åren och intresset för AI har ökat enormt. Trots detta är det få svenska företag som implementerat AI i sin verksamheten och än mindre små och medelstora företag. I den här studien har vi tagit fram ett antal strategiska, organisatoriska och tekniska faktorer som är viktiga för att små och medelstora företag ska kunna skapa värde med hjälp

One of the most harmful social issues throughout the world is crime, making it an important subject to research. This essay investigates the relationship between violent crime and oil prices in Europe and Central Asia. The relationship is less researched than crime and other socioeconomic variables such as unemployment and economic growth. The casual relationship is tested using the PVAR model and

Cancer immunotherapies activate the immune system to overcome tumor resistance and restore the antitumor immune response, however, excessive activation of the immune system may also affect normal tissues and organs and cause immune-related adverse events (irAEs) of varying severity. Current in vitro assays used for testing and predicting of irAEs induced by immunotherapeutics are associated with s

Despite growing interest in movements, mobilisations and communities rising up against extractivism, little research has focused on the radical political potential these mobilisations bear for envisioning just and sustainable futures. Taking the Right to Say NO in South Africa as a case study and point of departure, this thesis examines development alternatives envisioned within anti-extractivist

Trots att informationssäkerhetspolicyer är väsentliga för informationssäkerhetsarbetet visar tidigare forskning att organisationer inte uppdaterar dessa efter behov. Med hjälp av det lånade begreppet responsivitet från organisatorisk agilitetslitteratur, syftar denna studie på att tillhandahålla förståelse för hur organisationer bedriver sitt arbete med att underhålla informationssäkerhetspolicyer

The COVID-19 pandemic has disrupted our lives and created wide-reaching impacts. Societies worldwide have confronted the crisis with grassroots mobilisation and social resilience. Civil society uncovers injustices by actively participating in the local decentralised pandemic response. This micro-level study provides insight into a long-standing social movement organisation’s framing of the crisis.

This qualitative study applies to young men between the ages of 18 and 21 who live in community homes (HVB hem), and have an ongoing substance abuse and addiction problem. The focus will be on the motivation and treatment that from the young men's perspective promotes the process of change to start a life without addiction. This activity, which fulfills an incredibly essential function in soci

Looking at the contemporary practices of multi-story timber buildings reveals to us that they usually follow the tectonic language of concrete constructions. However, with a paradigm shift to sustainability, we need to rethink the way we design and construct. In other words, with a material alteration from concrete as the primary material of the 20th century to mass timber as the sustainable mater

The present study was a replication report where it investigates suppression-induced forgetting (SIF) using the think/no-think experimental paradigm and the thought avoidance strategy when tested using the same cue (same probe) and novel cue (independent probe) during learning of neutral words. Same probe test has been examined to demonstrate high sensitivity in detecting inhibition via the relati

This thesis examines the view of what a crown witness system could mean in terms of the witness’ willingness to testify in a criminal case. The aim was to answer how relations and emotions influence the witness’ tendency to give dictum about crimes. A further aim was to show what people with experience of meeting with witnesses think that a crown witness system applied to Swedish law, could mean f

The purpose of this thesis has been to investigate the liturgical practices of the Paschal candle in five different congregations within the Church of Sweden, and to analyse the underlying reasons for those practices; how and when is the Paschal candle used within the liturgy, and how is its usage interpreted and motivated by the congregations’ ministers and sextons? The thesis bases its findings

Literature shows that it is possible to induce placebo effects through classical conditioning. Literature also offers first evidence of a semantic memory retrieval enhancement effect elicited through a manipulation of expectancy, which may or may not fit the name of semantic memory retrieval placebo. The study here reported sought to discover whether a similar effect could be produced for episodic

Riskhantering inom försörjningskedjor har påvisats vara relevant på grund av dess sårbarhet för risker från flera håll. De senaste åren har världens försörjningskedjor utsatts för mer omfattande risker och kriser än vad som kunnat föreställas, såsom Covid-19 och anfallskrig mellan Ryssland och Ukraina. Därmed identifierades ett kunskapsgap i tidigare forskning kring dess användbarhet vid omfattand
