The field of radial turbines is wide and radial turbines of today find applications inareas as diverse as small gas turbines; turbochargers for cars, buses, and trucks, railwaylocomotives, and diesel power generators; cryogenic and process expanders; rocket engineturbopumps; and specialty steam turbines, [12]. The three-dimensional flow inside aradial turbine is complex an
This thesis investigates labor exploitation within China's food delivery industry, focusing on dominant platforms such as Meituan and Eleme amid the rapid growth of the digital economy. The study is motivated by concerns about the working conditions of delivery workers, who often lack formal contracts and protections, leaving them vulnerable to exploitation, especially through the use of algor
The unattended collection and delivery point (UCDP) is one of several solutions to address the delivery issues arisen by increasing online retail sales. There are four solutions of the UCDP concept: the traditional parcel locker, the automated box design, the automated pillar design and the cart design. Moreover, the physical dimensioning of a UCDP mainly needs to consider the number of orders, or
Background Intracellular delivery of antimicrobial agents by nanoparticles, such as mesoporous silica particles (MSPs), offers an interesting strategy to treat intracellular infections. In tuberculosis (TB), Mycobacterium tuberculosis avoids components of the immune system by residing primarily inside alveolar macrophages, which are the desired target for TB therapy. Methods and findings We have p
Lipid nanoparticles (LNPs) have emerged as an efficient platform for mRNA delivery, in which ionisable lipids play a central role in intracellular uptake and endosomal escape. In this study, the influence of different ionisable lipids on cellular uptake, endosomal damages and mRNA release kinetics was investigated to identify promising LNP compositions for effective mRNA delivery. Dose-dependent L
Abstract The right-wing populist party The Sweden Democrats became the second largest party in the Swedish election of 2022. Their electoral success can be traced to populistic discursive methods. There are several political strategies commonly used by right-wing populist parties. This paper aims to analyze such strategies in the Sweden Democrats rethorics but also in other right-wing parties not
The double compression-expansion engine concepts (DCEE) are split-cycle concepts where the compression, combustion, expansion and gas exchange strokes occur in two or more different cylinders. Previous simulation studies reveal there is a potential to improve brake efficiency with these engine concepts due to improved thermodynamic and mechanical efficiencies. As a continuation of this project thi
1. Thousands of lakes in the Northern Hemisphere are experiencing a continuous increase in water temperature and colour. While increasing temperature is an effect of climate change, several factors are suggested to drive the increasing water colour, including climate change, altered land use and reversed acidification. 2. In this mesocosm study, we study the effects on pelagic production and sedim
We jointly optimize Discontinuous Reception (DRX) cycle length and LTE scheduling to minimize mobile devices' energy usage for video delivery, utilising the now well-established potential to predict future channel conditions in cellular networks. Employing in-network caching, we set a strict buffer constraint which provides zero buffer underflow to improve Quality of Experience. Our study provides
Pancreatic cancer is the fourth leading cause of cancer-related death with a 5-year survival of less than 6%. The only potential cure for pancreatic cancer is by surgical removal of the tumor. However, most patients present with an advanced and metastasized disease at the time of diagnosis, leaving only around 15% of patients eligible for surgery. For the majority of patients, palliative chemother
BACKGROUND: In this study, electrochemotherapy (ECT), i.e. tumour treatment based on local augmentation of intracellular drug delivery from short, intense electric pulses, was evaluated in rats with an adenocarcinoma implanted into the liver. Tumour response and concentrations of macrophages and T-lymphocytes (CD4 and CD8) in and around the tumour were measured.MATERIALS AND METHODS: Rats were tre
Although many therapeutically active peptides and proteins have been developed there is a lack of topical pharmaceutical products on the market containing these sensitive molecules. The main reasons may be lack of stability and a limitation of larger molecules to penetrate into the skin. In this study we investigated the possibility to develop a peptide formulation which enables follicular permeat
Thesis purpose: This thesis studies the subject of exclusivity by examining the narratives of consumers in the subculture of equestrian sports in Sweden. Through socio-cultural analysis of the value of cultural capital, we seek to build an understanding of how myths and stories create an image of exclusivity and influence taste and consumption in the equestrian field. Methodology: In-depth intervi
