Inom läkemedelsindustrin är det väldigt viktigt att göra en noggrann kontroll av läkemedel så att de är tillräckligt rena för personen som ska använda dem. En vanlig analysteknik i industrin är HPLC (High Performance Liquid Chromatography), som används för att separera och identifiera olika ämnen i exempelvis krämer eller tabletter. Analysmetoden används för att upptäcka orenheter i produkterna. HPLC is one of the most widely used analytical techniques in the pharmaceutical industry used for separation and identification of compounds in complex formulations. Despite its advantages, HPLC method development remains challenging. This is due to the need to optimize multiple interdependent parameters simultaneously, while gaining high precision, reproducibility, and efficiency. Even minor cha

This thesis explores the possibilities of integrating semantic transport information in the context of 3D-city modelling by implementing transport surfaces according to standards defined by the 3CIM specification, an extension of CityGML. This approach aims to automatically generate transport surfaces in LOD1 and LOD2, based on the Stockholm city basemap in combination with road geometries that re

Carbon sequestration and long-term carbon storage are fundamental characteristics of northern peatland ecosystems. A key process influencing the carbon balance is the decomposition of litter and peat, which not only emits carbon to the atmosphere but also releases dissolved organic carbon (DOC) to recipient waters. However, these processes are susceptible to shifts, as climate change and managemen

In an urbanizing world, challenged by climate change and rising temperatures, street vegetation can help mitigate urban temperatures. However, scaling the understanding of street vegetation’s cooling effects from local observations to the city level introduces challenges. While several studies have assessed the influence of street greenery on land surface temperature (LST) at the city scale using

Skal danskerne til at lære dansk af svenskerne? Forskning og undervisning i dansk nedlægges ved Roskilde Universitets Center i 2028. Det sker, selv om 1/3 del af skoleeleverne på den sydlige del af Sjælland ikke bliver godkendt i dansk til eksamen i 9.klasse. I fremtiden skal danskerne måske til at rejse til Lund, Göteborg, Uppsala, Stockholm og Växjö for at studere deres eget sprog.

Dennis Olsson recenserar "Året hos Hyperboréerna", "Dagar den sommaren", samt "Norgesviten" av Jesper Svenbro, för poesikritksajten Örnen och Kråkans publik.

Cancer is the leading cause of death in the world. Multiple different treatment options are available, target therapy and immunotherapy being two. One potential target is Fibroblast Growth Factor Receptors (FGFRs) and there are both available treatments and new treatments being investigated for this. However, only around 25% of patients benefit from the immunotherapy treatment Immune Checkpoint In

Textile waste presents significant harm to the environment, prompting the development of advanced textile recycling technologies. One such process recycles cellulosic fibers using zinc chloride (ZnCl2) at certain hydration levels to dissolve the cellulose, which is later precipitated by the addition of water and can be re-spun into new fibers. However, this process uses large amounts of zinc chl

I detta examensarbete undersöks det hur modeintresserade unga kvinnor i åldrarna 20-29 år utformar sina köp- och försäljningspraktiker av kläder på digitala secondhand-plattformar under en ekonomisk kris. Uppsatsen syftar till att utveckla befintlig forskning genom att skapa förståelse för unga kvinnors secondhand-praktiker under en ekonomiskt osäker tid. Studien utgår från en kvalitativ metod och

This thesis investigates the implementation of China’s Solar Energy for Poverty Alleviation Programme (SEPAP), a state-led initiative introduced in 2014 to address rural poverty while supporting the expansion of the domestic photovoltaic (PV) industry. Rather than evaluating outcomes, the study explores how SEPAP was translated from central policy into local practice across two counties in Jiangsu

This research explores the socio-economic impacts of flooding on women's livelihoods in Banjul, The Gambia, a city that is increasingly vulnerable to climate change and flooding disasters. With increasing flooding in coastal regions, Banjul is among the cities with significant challenges, particularly for women, who are usually marginalized and disproportionately affected in case of disasters.

Undersökningen syftar till att öka förståelsen för hur yrkesidentitet uttrycks och formas i ett framväxande yrke, samt vilka organisatoriska villkor som påverkar yrkesidentitetens utveckling. Studien bygger på en kvalitativ fallstudie av det framväxande yrket trafikstyrning, ett yrke som präglas av låg synlighet, inom en svensk lagerverksamhet. Genom tolv semistrukturerade intervjuer analyseras hu

During the winter smog season, Punjab experiences some of the world’s most hazardous air quality levels, largely driven by the open-field burning of agricultural residue. In response, the provincial government introduced a 60 percent subsidy for Super Seeders — tractor-mounted implements that mulch crop residue in-field, eliminating the need for burning. This thesis presents a formative, farmer-ce

Introduction: Synthesis of novel aliphatic POCOP pincer complexes with β-blocking alkyl groups. Background: An issue with Aliphatic POCOP pincer complexes is that the sought-after C=M bond is unstable with previous attempts forming aromatic groups or decomposing completely under heating. By introducing β-blocking elements to the aliphatic POCOP pincer ligands could this mitigate the decompositio

Achieving the Agenda 2030 requires the adoption and implementation of the goals at all levels of the government from the national to subnational level. Cambodia, as a member state of the UN, under the Cambodia Sustainable Development Goals (CSDG) Framework has also made a commitment to localise the SDGs to the subnational level. However, after the adoption of the CSDG framework in 2018, the progre

Adaptive reuse of existing buildings as a part of the circular economy principle has become a more common approach to promote sustainable development, due to increasing urban densification and environmental concerns. Ventilation systems, as a major contributor to energy use in buildings, often face complete replacement during building reconstruction, despite their potential for extended service li

The relationship between development and democracy is robust and enjoys strong scholarly support. While research traditionally has favored country-level comparisons based on objective indicators when studying this relationship, this study crafts an individual-level, perceptions-based index of development, and two measures of support for democracy as a regime type, to approach the relationship.
