Hydrodynamic cavitation occurs in high-pressure homogenizer (HPH) valves, causes wear and influences emulsification. Substantial advances have previously been made studying HPH cavitation in experimental systems. However, there is a lack of understanding on how cavitation develops in industrially relevant valves. The series applies CFD to address this knowledge gap. This part combines a previously

Introduction: Propolis is a sticky substance produced by honeybees from plant resins collected from locally growing vegetation. Its chemical composition varies depending on the plant species visited by the bees. Contact dermatitis is commonly reported following exposure to cosmetics containing propolis or following the intake of food supplements. Objectives: To investigate the prevalence of contac

Thermal modification is a widely used technology for enhancing the dimensional stability and durability of wood. However, thermal degradation reactions in wood are complex and depend on the process conditions applied. Degradation products from thermal wood modification are expected to affect the wood chemistry and the wood–water interactions of the thermally modified wood. In this paper, we invest

In food engineering in general and in liquid food processing specifically, accurate measurement of particle size is important, both for product development and daily quality control. Laser diffraction is the dominating method for particle size measurement of e.g., plant cell structures in food and beverage processing. However, the accuracy of the method can be questioned since these particles diff

This study examines the adsorption and desorption behaviors of phosphorus (P), arsenic (As), fluoride (F), and chromium (Cr) in aqueous solutions on green materials such as cork bark (CB) and pine bark (PB). These materials are characterized by active functional groups and net negative charges on their surfaces and porous structures. The evaluation considers variations in contaminant concentration

As the field of neural organoids and assembloids expands, there is an emergent need for guidance and advice on designing, conducting and reporting experiments to increase the reproducibility and utility of these models. In this Perspective, we present a framework for the experimental process that encompasses ensuring the quality and integrity of human pluripotent stem cells, characterizing and man

A crystallogenesis study of human transthyretin using the counter-diffusion method is described as an alternative to conventional convective vapour diffusion and batch approaches for protein crystallization. The X-ray diffraction results show systematic trends that exhibit unique patterns of crystallization and high crystal quality as well as a remarkable degree of coherence within extended crysta

During the last decades, MgMg and alloys gained interest as degradable implant materials: its mechanical propertiesMechanical properties are close to bone and a second surgery for removing them can be avoided. Properties are gained from chemical composition and processing as they are responsible for microstructureMicrostructure development. However, this is not good enough in many cases. When the

Cavum septum pellucidum (CSP) is commonly observed upon neuroimaging examination in individuals exposed to repetitive head impacts (RHI) and post-mortem in cases with chronic traumatic encephalopathy. Consequently, CSP has been proposed as a potential biomarker for RHI-related neurodegeneration, yet prevalence estimates of CSP across other neurodegenerative diseases and its clinical implications a

Simethicone, a widely used anti-foaming agent in pharmaceuticals, consists mainly of polydimethylsiloxane (PDMS) combined with silica gel. While it is safe in pharmaceutical use, concerns have been raised about its degradation into cyclic siloxanes—specifically D4, D5, and D6—which can cause environmental and health hazards. This study investigated the degradation behavior of simethicone under var

Depression är ett stort problem i samhället idag, det vanligaste läkemedlet som används för behandling av det är någon typ av Selektiva serotoninåterupptagshämmare (SSRI). Dessa läkemedel är effektiva men kräver regelbundna doser och har otrevliga sidoeffekter såsom viktuppgång, emotionell avtrubbning och sexuell dysfunktion. Psilocybin har nyligen fått uppmärksamhet som ett alternativ till dessThe scientific interest in psilocybin has recently been reignited, the research community has once again begun to investigate the promising potential that psilocybin offers in the area off treatment of depression and PTSD. An obstacle to the research of psilocybin is that today pharmaceutical grade psilocybin is produced using an inefficient and thus costly synthetic process. This hampers the rese

This research explores how elderly residents in Gothenburg, Sweden, interact with and access-urban blue and green spaces, how this may vary in warmer temperatures, and the applications this-can have in current climate adaptation planning in the city. This study considers a localized focus-area situated in Gothenburg Municipality’s Climate Adaptation Plan. Using a mixed methods-approach, this resea

This disquisition explores the possibilities to install a battery storage situated in a gasturbineplant to enable a start up of the gasturbine in the case of a powerfailure. Since powerfailures are rare, the battery will mostly and to a large extent be unused, this creates an economic dilemma. Uniper has taken in and recieved a tender which includes and discribes a battery with a larger storage sy

The resistivity of the semi-conducting material in high voltage direct current cables were studied under a variety of conditions. A wide theoretical background was also created, summarizing previous works within the field and providing useful explanations for the characteristics seen in the results. The semi-conducting material works as a protective shield for the insulation of the cable, protecti

Sveriges skogar är viktiga för klimatet! I Sverige är kalhuggning med efterföljande återplantering den vanligaste metoden för att bruka skog (så kallat rotationsskogsbruk). Med en hög andel skog som är brukad är det viktigt att förstå vilken påverkan på klimatet det har. I denna studie visas tydligt att utsläppen av koldioxid ökar när skogen huggs ner, vilket bidrar till den globala uppvärmningen.Levels of carbon dioxide (CO2) and other greenhouse gases (GHG) are rising, thereby acceler-ating global warming and related effects on the environment. Forests are an important ecosystem and can act as carbon sinks, providing a buffer against these effects. However, disturbances such as clearcutting can turn the forests into carbon sources. In this project, the effects of clearcutting on the carb

In the last ten years, Sweden has seen a noticeable increase in shootings involving young people, which has led to growing media attention and public concern. This thesis explores how Swedish newspapers frame these shootings and how those frames align with public discourse in an online forum in Sweden. The study examines the connection between media framing of youth-involved shootings and public d

This study employs large-scale Chinese pre-trained language models (BERT series) and the Fill-Mask Association Test (FMAT) to systematically measure gender- and age-based, as well as class-based, heterogeneity in marital status stereotypes embedded in natural language. Four sub-studies were designed to examine the effects of age (22–40 years), residence (urban vs. rural), and education (high vs. l

Misleading health information remains a central concern in medical sociology and public health due to its harmful effects on individuals and society. As health information-seeking increasingly shifts to digital platforms, Large Language Models (LLMs)—now commonly used as search engines—have intensified concerns about the spread of health misinformation. This study examines the potential for LLMs t

Så kan skogsägare bromsa klimatförändringarna – och samtidigt få betalt för det. Privata skogsägare kan spela en nyckelroll i Sveriges klimatarbete – men då krävs ersättning och tydligare regler. Klimatförändringarna har ökat behovet av lösningar som både minskar utsläpp och binder koldioxid. Skogen är en naturlig kolsänka – alltså ett ekosystem som lagrar koldioxid – och därför är skogsbruket i Since pre-industrial times, increased greenhouse gases in the atmosphere has contributed to climate change affecting all ecosystems. As a result, global and national commitments have been made to reduce emissions by enhancing the number and effectiveness of carbon sinks. To meet the national climate targets, Sweden has proposed financial compensation for forest owners who postpone harvesting. This
