During the past few years the focus on bioprocess monitoring and control has increased. An area still under intensive development is the sampling methods for efficient and rapid analysis during fermentations. In this thesis, an online-sampling and monitoring scheme was developed using the versatile automated continuous flow system (VersAFlo) for recombinant protein production. From the implementat
With modern day interest to continue the reduction of harmful emissions and improve the efficiency of combustion devices, the need to further improve upon accuracy and ability to describe combustive processes is of high value. Nowadays, multiple capable point (0D) and two-dimensional measurement (2D) techniques exist for flame investigation, however as combustion nearly always is a three-dimension
The accuracy and portability of depth cameras have increased by a lot in recent years, which allows for advanced 3D scanning of the environment for robotic applications. In this thesis we have developed a system that uses a depth camera mounted on a robot arm to identify and localize arbitrary objects, and give hints on how to move the camera to get better localization results. The system works by
CellaVision develops automated microscopy for blood analysis. Their products can pre-classify 19 different types of white blood cells and support the medical technologist performing the final classification. CellaVision provides reference cells. The reference cells are a fixed set of cells handpicked by a technologist, chosen to be typical for that specific class. The reference cells are static, i
The advantages with infrared heating and the fact that the technology has become significantly more inexpensive opens up a bigger interest to develop products using infrared heaters further. What will the future kitchen look like? How can infrared technology develop and create more conventional and intellectual products processing our food? By pushing the limits of the technology today the main
Utveckling och testning av reaktorer för katalysmätningar Katalysatorer är oumbärliga i såväl livsprocesser som industriella tillämpningar. Bilismen är ett exempel där katalysatorer används vid såväl bränsletillverkning som avgasrening. Men detta är långt ifrån det enda användningsområdet. Katalysatorer är också delaktiga i tillverkningen av uppemot 90% av alla kemikalier. Industriella katalysaIn this project four reactors for studies of heterogeneous catalysis have been developed. They were tested using case studies, especially concerning methane oxidation over palladium. The test measurements showed that the reactors work or would work very well after slight modifications. The first reactor allowed for activity measurement using mass spectrometry for temperatures up to at least 1000°C
Popular science Carbon cycle has great importance in all time scales for its inter-connected relation and response with climate system. Increased anthropogenic emission of CO2 is alleged to impact the climate system in the future, which will affect the feedback between carbon cycle and climate change. In this project, a climate-carbon cycle feedback analysis has been conducted by using long simula
Antalet personer som lever med en kronisk sjukdom ökar, detta som en konsekvens av bland annat en snabbt ökande äldre befolkning. Kroniska sjukdomar orsakar inte bara mänskligt lidande, utan är också en ekonomisk börda för samhället. För att lindra lidandet och minska kostnaderna kopplade till kroniska sjukdomar kan användandet av digitala hälsotjänster vara en möjlighet. För närvarande är förväntThe amount of people living with chronic diseases is increasing. Chronic diseases do not only induce human suffering, it is also an economic burden on society. To ease the suffering and reduce the costs connected to chronic diseases, the usage of digital health services might be a possibility. Currently, the expectations on such services are high, but not met. To better meet the expectations, this
Fysiska och juridiska personer är i någon form av förhållande med varandra baserat på olika omständigheter. När två parter är oense om en fråga vill de givetvis lösa situationen på något sätt. Denna lösning ligger för många hos statliga domstolar där den ena parten stämmer den andra parten vid tingsrätten som första instans. I vissa tänkta utfall är förhållandet baserat på ett avtal som parterna Natural and legal persons are in some form of relationship with each other based on different circumstances. When two parties disagree about an issue, they naturally want to resolve the situation in some way. For many, this solution lies with state courts where one party sues the other party at the district court as first instance. In some scenarios, the relationship is based on a contract that t
This degree project aims to develop standard methods for determination of the size distribution in different samples using laser diffraction, as well as to create methodologies for development of new methods for unknown samples. The size distribution is crucial to understand for pharmaceutical products since it affects properties such as the stability and bioavailability of the product. A way to
The beverage packaging industry is growing rapidly, driven by urbanization and changing lifestyles. Demand for packaged beverages with extended shelf life is driving sales of products with superior barrier properties, due to the high environmental impact of food waste compared to packaging waste. Despite progress, packaging waste represents more than a third of total waste. Thus, milk and plant-ba
The thesis explores the decision-making process of sustainable entrepreneurs for securing external funds by adopting the “triple bottom line” research perspective (Hall et al., 2010; Sarango-Lalangui, 2018). It delves into how sustainable entrepreneurs assess and exploit funding opportunities while balancing their economic and non-economic goals. The research addresses two primary questions: what
The aim of this study was to deepen the understanding of how community-based water management approaches facilitate sustainable and collective action (SCA) in the context of increasing water insecurity in Costa Rica. Applying a qualitative approach, based on fieldwork in Guanacaste, Costa Rica, including semi-structured interviews and a digital community survey, the study uncovers facilitating fac
