The aim of the Master’s thesis was to evaluate the performance of two existing extraction nozzles at Nederman, and to use the findings to create a concept for a new nozzle. The purpose of the new nozzle was to be attached to a welding cobot, resulting in a change in requirements and design possibilities. The project followed the product design process as described by Ulrich and Ep- pinger, consist
Samhällsreformer och utvecklingen inom den svenska offentliga sektorn har omformat förutsättningarna för socionomyrket och andra professioner samt förändrat socionomernas arbetsområde. Jag har använt begreppet karriär för att undersöka förändringar inom socionomprofessionen, eftersom det ger ett perspektiv för att belysa stabilitet och förändring samt kan fånga både externa och interna krafter i p
A novel technique for CO2 removal using a precipitating amine absorption system is being studied for potential use in biogas upgrading and carbon capture and storage (CCS). The system uses the sterically hindered amine 2-amino-2-methyl-1-propanol (AMP) mixed in different concentrations with the organic solvent N-methyl-2-pyrrolidone (NMP). In the current work, the physical solubility of CO2 in sol
Background: The objective of this study was to investigate the relationships between atopic dermatitis (AD) and other common chronic health conditions in adults. Methods: A cross-sectional survey was sent to a randomly selected population sample of 78,004 adults in Sweden. The questionnaires included measures of self-reported physical and mental health. Binary and multinomial logistic regression w
Vitrified bonded aluminum oxide grinding wheels are widespread in use for many applications in grinding, such as internal plunge grinding. However, there are challenges when it comes to the measurement, analysis and (geometric) modeling of their topography, which is crucial to understand and model the influence of the topography on the process behavior. Methodological advances allow for the detail
This study contributes to the growing literature on mobile work by examining the coordination of safety practices in public transport in Stockholm. We explore how safety, a critical and evolving theme in mobility studies, intersects with mobile work and its associated coordination challenges. Since the introduction of safety policies, security guards have focused on ‘circulatory maintenance’, a pr
The accuracy of pore size distributions (PSD) obtained from gas adsorption and cryoporometry is compromised by the presence of advanced adsorption and advanced melting effects, respectively. In order to improve PSD accuracy, it is necessary to know the extent of such effects. In this work cryoporometry and adsorption have been combined to study the onset of advanced melting effects in a sample par
Buffer management for biopharmaceutical purification processes include buffer preparation, storage of buffers and restocking the buffers when needed. This is usually performed manually by the operators for small scale operations. However, buffer management can become a bottleneck when running integrated continuous purification processes for prolonged times, even at small scale. To address this iss
Excessive use of water resources in combination with climate change threaten to significantly reduce groundwater in arid and semiarid regions. We studied the effects of climate change on the groundwater level for the important Dehgolan Aquifer in northwestern Iran. The water level in this aquifer has dropped by about 35 m during the last 30 years. Soft computing techniques were used together with
Real-time monitoring of patient’s blood metabolites, such as glucose and lactate, could potentially improve surgery and recovery outcomes for patients in surgical and intensive care units. Our enzyme thermometric biosensor which is based on flow injected calorimetric determination of immobilized enzyme reaction is capable of performing continuous, fast, and quantitative analysis of metabolites usi
Many conservative public figures have claimed that Google Search exhibits a liberal bias in the links presented. Surprisingly, perhaps, the few scientific studies conducted so far have tended to support this claim. In the study reported here, we compared Google search engine result pages (SERPs) for 8 terms related to immigration across 8 geographically distinct locations (municipalities). For eac
BACKGROUND: In 2013, it was discovered that a subset of the population in Ronneby, Sweden was exposed to high levels of perfluorinated compounds (PFAS) from drinking water that had been provided by the local Brantafors waterworks and was contaminated by fire-fighting foam from a nearby airport. The start and time-course of population exposures are not known.OBJECTIVE: To investigate the start of P
Background: Butaro Cancer Center of Excellence (BCCOE) was founded to serve Rwanda’s rural low-income population, providing subsidized cancer diagnosis and treatment with transport stipends for the lowest-income patients. We examined whether travel distance to BCCOE was associated with advanced-stage diagnoses and treatment completion. Methods: We conducted a retrospective cohort study using medic
New mapping and laboratory studies of the impactites at the Gardnos impact structure (Norway) show a variety of impact-deformed rocks. Our mapping and petrographic analyses have subdivided these breccias into three distinct categories: (a) melt-bearing sueivitic breccias, melt-bearing polymict breccias; (b) melt-free, polymict lithic impact breccias; and (c) monomict lithic impact breccias. This i
Hardwood spent sulphite liquors (HSSLs) are by-products from the pulping industry rich in pentoses, which are not yet fully exploited for bioprocessing, namely for the production of bioethanol. The sustainable fermentation of pentoses into bioethanol is a challenge to overcome. Besides sugars, HSSLs contains inhibitors that decrease the possibility of bioprocessing of these by-products. Neverthele
Introduction Asthma may increase the risk of comorbidities and systemic inflammation, but population data are scarce. This study aimed to compare comorbidities and systemic inflammation between those with and without current asthma and to identify characteristics linked to comorbidities and biomarkers. Methods In a cross-sectional analysis of 28 828 people aged 50–64 in the Swedish CArdioPulmonary
Infections caused by anaerobes are common in children. However, limited data are available on bloodstream infections caused by these bacteria in Europe. A multicentre retrospective observational study was conducted over a 4-year period (2020–2023) across 44 European hospitals to analyze all anaerobes isolated from blood cultures. The study examined the epidemiology and antimicrobial resistance pro
The importance of providing mechanisms and tools that effectively support the transition from implicit to explicit representations of Learning Design has been emphasised by previous research in the field of Technology-Enhanced Learning (TEL). In addition, the benefits of Game-based learning approaches have been long documented in the educational research literature. The paper presents the design,
This paper examines how the returns and volatility of Chinese ADRs listed at NYSE are affected by their host market (US), underlying market (Hong Kong) and local market (Shanghai). Using a GARCH spillover model and data from 1 January 2002 to 30 September 2007, we find that the volatility spillover from US (host market), Hong Kong (underlying market) and Shanghai (local market) to Chinese ADRs, fo
The following essays checks whether the Swedish stock market (represented by OMXS30) supports the weak efficiency of the EMH by observing whether the stocks contain a unit root and whether one can use trading strategies to create abnormal profits. The AR(1) model of the stock prices have a unit root coefficient very close to 1, thus they are trend stationary but have a very long memory. This model
