Detektion av utsläppsplymer med avancerat ekolod – Undersökning av utsläpp av avloppsvatten från pappersbruk i havet med EK80, CTD & filmmaterial

Nymölla är en liten kustnära tätort belägen i nordöstra Skåne. Kusten utanför Nymölla, en del av västra Hanöbukten, är uppsatsens geografiska fokusområde. Under 1960- och 1970-talen anlades både massa- och pappersindustri i Nymölla, två betydelsefulla industrier för Sverige, både gällande export och ekonomi. Ett exempel av Sveriges femtiotal massa- och pappersbruk är Nymölla Bruk, en produktionsan

Flow regime impact on brazed plate heat exchanger in chiller application

Optimering av flödet till en förångare i ett kylsystem ökar effektiviteten. Experiment visar hur prestandan kan förbättras med geometriska förändringar i inloppsröret till en förångare med ett homogent flöde. Detta leder till en förbättrad fördelning av köldmedia i förångaren följt av förbättrad effektivitet. Snedfördelning av köldmedia i ett kylsystem påverkar systemets kylförmåga, men med geometRefrigerant systems such as chillers and are widely used to create a comfortable indoor climate, often incorporated in large buildings or offices. It relies on a refrigerant circuit that lowers temperature of a coolant via a heat exchanger, called an evaporator. The coolant enters a fan coil which lowers the surrounding air temperature in a desired space and recirculates back to the evaporator at

Remote Control Of A Hose For Concrete Pouring

The process of pouring concrete is very common in the construction industry. Typically, a person stands on top of reinforcements around the mold of the slab while manually pushing the hose, guiding it in a smooth side-to-side movement until an even pour has filled up the mold. Another person is positioned at a distance from the pouring end controlling the pump and thus the flow of concrete through

The data gathered in the following study aims to answer the research questions, and thus making sure the purpose of the study is distinctly reac

Monitoring self-assembly of Aβ40 using Differential Scanning Calorimetry

Alzheimers sjukdom är den vanligaste typen av demenssjukdom. Den har drabbat miljontals människor, men ännu finns det inget sätt att bota sjukdomen. Huvudorsaken till Alzheimers sjukdom tros vara ansamlingar i hjärnan av peptiden amyloid β som självmant kan interagera med andra peptider av sin sort och bilda mycket stabila och organiserade amyloida fibriller. En mängd monomera amyloida β peptider The aggregation of amyloid β in the brain is considered to be the main cause of the currently incurable Alzheimer’s disease. Research investigating fibrils is being conducted continuously. Despite this, there is an incredibly large knowledge gap in what we know about the aggregation process. This study aims to investigate the temperature influence on the Aβ40 aggregation process using differential

Vision transformers for segmenting organs and tissues in CT scans of arbitrary imaging ranges

Automatic segmentation of organs and tissues in computed tomography (CT) images can aid clinicians in anatomical contextualization for planning surgery or dosimetry. CT scans can cover varying axial ranges of the body. This thesis aims to develop a neural network based on vision transformers for segmenting organs and tissues in CT images of arbitrary axial ranges. Two models are presented, one bas

Investigation of Methods for Automating the Localization of Healthy or Unhealthy Lymph Node Tissue for Magnetomotive Imaging

Rectal cancer is a frequently diagnosed cancer type worldwide, approximately 700,000 people are diagnosed every year. The mortality is high due to the high risk of metastasis where it mainly spreads through the lymphatic drainage pathways. Unfortunately, there are no accurate methods used in the clinic for determining the spread, resulting in that extensive colorectal resection is the primary trea

Business Intelligence for Environmental Sustainability

This master’s thesis explores the importance of CSFs for business intelligence implementation for environmental sustainability initiatives from municipal employees’ perspectives, aiming to increase the understanding of the selected field. The qualitative study is based on semi-structured interviews with six employees. The collected data was analysed and discussed with a template analysis based on

Rearranging collective memory about nature: the case of Oatly

This thesis explores the practice of sustainability communication among emerging corporate entities in the food industry, contending that these actors utilise collective memory to advance their objectives. Employing Foucault’s archaeology and genealogy, the study scrutinises power dynamics within Oatly’s campaigns, aiming to comprehend how the discourse surrounding nature is shaped and how collect

Beyond the Hype: The Perceived Usefulness of Virtual Influencers in the Communication Industry

Virtual influencers (VIs) are computer-generated characters gaining traction in influencer marketing, particularly in the US and Asia.

Köldbryggor : Hur har kunskapen utvecklats i Sverige

Byggnaders energibehov behöver minska i kombination med att energiförsörjningen (el, värme, gas, med mera) behöver fasa ut an­vändandet av fossila bränslen för att motverka den pågående kli­matförändringen. Olika strategier kan tillämpas för att utforma och bygga/renovera energieffektiva byggnader. En viktig åtgärd, oavsett strategi, är att minska energibehovet, vilket i Sverige vanligtvis inne­fa
