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

According to the Intergovernmental Panel on Climate Change (IPCC), atmospheric methane (CH4) concentrations are considered a crucial factor in global warming, particularly in the near term, due to its high warming potential (~ 80 times more potent than carbon dioxide, or CO2) and shorter atmospheric lifetime compared to CO2. CH4 emissions have more than doubled since the industrial revolution and

The average Swede uses 140 liters of water everyday. This combined with the usage in industry means that Swedish municipal water treatment plants produce approximately 900 billion liters of clean and safe drinking water every year. This does not include the fact that all water flowing to a treatment plant needs to be treated before being sent back out into the environment. These facts hint at what

Uppsatsen har som syfte att kritiskt granska försvarlighetsbedömningen och excessbedömningen som görs i nödvärnssituationer. Ett psykologiskt perspektiv används för att analysera huruvida Högsta domstolen har skapat en för långtgående skyldighet att fly istället för att försvara sig med våld. Det är endast nödvärn vid brottsligt angrepp på person som behandlas. Jag använder mig av den rättsdogmatiThe purpose of this essay is to critically examine the Supreme Court’s judgments regarding the justifiability of self-defense and excessive self-defense. A psychological perspective is applied to analyze if the Supreme Court has created a too extensive obligation to escape instead of using violence to defend oneself. This essay only covers self-defense from criminal attacks on a person. I use a le

Det sen-Triassiska massutdöendet (STM) var ett av de fem stora massutdöenden i Fanerozoikum och inträffade för omkring 201 miljoner år sedan. Forskningen är enig om att utdöendet orsakades av vulkanutbrotten associerade med bildandet av den Centralatlantiska magmatiska provinsen (CAMP), som är kopplade till uppbrottet av superkontinenten Pangea. De omfattande vulkaniska utsläppen av CO2 och SO2 leThe end-Triassic mass extinction (ETE) was one of the five big mass extinctions of the Phanerozoic and occurred ~201 Ma ago. Research agrees that the main triggering factor for the ETE was the eruptions of the Central Atlantic Magmatic Volcanic Province (CAMP), linked to the break-up of the supercontinent Pangaea. The large amounts of CO2 and SO2 released from the volcanic eruptions had a series o

Detta examensarbete ämnar att undersöka integration av tre olika teknologier till en havsbaserad vindkraftspark, om det är ekonomiskt gynnsamt samt hur kraftfluktuationerna till elnätet påverkas. Genom att kombinera olika förnybara kraftsystem kan man minska variabiliteten och kostnaderna kopplade till installation och drift av systemen. Även fast investeringar i annan förnybar energi utöver vindkThe high penetration of wind power is increasing the intermittency and power variability into the existing power grid. This is forcing industries to look for optimal configurations in order to improve their systems performance and minimize these effects from the power production method. Studies show that there are different ways of reducing the power variability and therefore stabilize the energy

Since the 1950's, mass tourism has become a considerable part of modern western culture. Examining where, why and how people have traveled can tell us a lot about people's habits and cultural frames of reference. Yet, the area of tourism history is fairly uncharted, with travelogs being one of the more prevalent objects of interest for academic research. Research focused on travel guides a

Det boreala skogslandskapet har allvarligt fragmenterats på grund av mänsklig exploatering, vilket har lett till en nedsättning av deras omfattande värde i, bland annat, ekosystemtjänster, biologisk mångfald, och kultur. För att bevara det boreala skogslandskapet är det avgörande att skydda de kvarvarande fragmenten av landskapet samtidigt som att återställa den strukturella och funktionella ansluBoreal forest landscapes have undergone severe anthropogenic fragmentation and their enormous values concerning, e.g., ecosystem service, biodiversity and culture are hazarded. Maintenance of the remaining intact boreal forest landscapes and restoring the structural and functional connectivity among these remnants are essential for boreal forest conservation. In Sweden, such conservation tasks are

År 2022 genomfördes en omfattande reform av den svenska arbetsrätten, med fokus på bland annat att modernisera lag (1982:80) om anställningsskydd (LAS). Reformen utgick från januariavtalet 2019 där regeringen åtog sig att lägga fram lagstiftningsförslag som stämde överens med en eventuell partsöverenskommelse framtagen av arbetsmarknadens parter vilket resulterade i ett nytt Huvudavtal som blev grIn 2022, a major reform of Swedish labour law was implemented, with one of its key objectives being the modernisation of the Employment Protection Act (LAS). The reform originated from the 2019 January Agreement and granted certain labour market organisations an active and norm-setting role in the drafting of legislative proposals. The government committed to presenting legislative initiatives in

OBJECTIVES: To describe the prevalence of cardiovascular disease (CVD) at the time of diagnosis of adult-onset type 1 (T1D) and type 2 (T2D) diabetes, in a recent cohort and compare to a previous cohort from the same region. Further, to explore factors influencing the prevalence of pre-existing CVD, including age, sex, body mass index (BMI) and C-peptide; in the later cohort also heart failure, hy

Cellulosa är den vanligaste biopolymeren på jorden och en viktig reservoar av organiskt kol i terrestra ekosystem. I skogar kommer mycket av denna cellulosa från trä och bryts ner av saprotrofa basidiomyceter. Dessa svampar klassificeras traditionellt som vitröta eller brunröta baserat på deras sönderfallsmekanismer i lignocellulosasubstrat. Huruvida dessa funktionella kategorier förblir distinktaCellulose is the most abundant biopolymer on Earth and a major reservoir of organic carbon in terrestrial ecosystems. In forests, much of this cellulose originates from wood and is decomposed by saprotrophic basidiomycetes. These fungi are traditionally classified as white rot or brown rot species based on their decay mechanisms in lignocellulosic substrates. Whether these functional categories re

Despite the average 5-year survival rate exceeding 85%, childhood cancer is still the most common cause of disease-related death among children in Sweden. A cancer diagnosis is profoundly traumatic not only for children themselves, but also for the entire family, particularly the primary caregivers, their parents. This project aimed to investigate the extent to which a childhood cancer diagnosis a

Group C and G streptococci (GCS/GGS) and group A streptococci (GAS) belong to β-haemolytic streptococci (BHS). GCS/GGS can further be species determined to S. dysgalactiae, whereas S. pyogenes are GAS. S. dysgalactiae and S. pyogenes cause similar diseases, (e.g., skin and soft tissue infections, erysipelas, bacteraemia, and infective endocarditis (IE)). Erysipelas often presents as a sharply dema

Background: Policies that promote aging in place are common in Sweden and many other countries. However, the current housing stock cannot sufficiently accommodate a population aging in place considering how functional capacity and housing needs change as people age. To be suitable for all regardless of their functional ability, housing should be designed or adapted to facilitate the performance of

Background: In many settings, health care service provision has been modified to managing COVID-19 cases, and this has been affecting the provision of maternal and child health services. The aim of this study was to assess trends in selected maternal and child health services performance in the context of COVID-19 pandemic. Methods: A cross-sectional data review was conducted in Addis Ababa, Ethio

The burden of cardiometabolic diseases is increasing worldwide. Early detection of high-risk individuals is essential for appropriate diagnosis, better treatment outcomes, quality of life and lower health related costs. Aims: The overall aim of this thesis is to investigate the possible associations between plasma proneurotensin (Pro-NT) and risk of cardiovascular disease (CVD), type 2 diabetes (T

Context. The formation and evolution of the Galactic bulge and the Milky Way is still a debated subject. Observations of the X-shaped bulge, cylindrical stellar motions, and the presumed existence of a fraction of young stars in the bulge have suggested that it formed through secular evolution of the disk and not through gas dissipation and/or mergers, as thought previously. Aims. Our goal was to
