The main goal of this project was to investigate how the thermal stability of two different types of polyhydroxyalkanoates; poly(3-hydroxybutyrate) and poly(3-hydroxybutyrate-co-4-hydroxybutyrate) were affected when washing them with acid solution. Initially, four different acids were used: citric acid, hydrochloric acid, formic acid and acetic acid. Citric acid gave the best results for both biop
Critical infrastructure is essential for a functioning society because of the services and goods they provide. Within these infrastructures there are several departments whose functionality is critical to society and when exposed to stress can lead to societal consequences. Therefore, it is important for the department within the critical infrastructure to have a solid crisis and continuity prepar
Abstract Title: Developing an Inventory Control Policy and Forecasting Model for an E- Commerce Company Authors: Patrik Lorentsson & Nilan Nabavieh Supervisor: Johan Marklund, Department of Industrial Management and Logistics Background: Increasingly competitive business environments forces companies to develop better control of the material flows in their supply chain. Inventories are oft
Overheating in buildings is a growing public health hazard becoming more prevalent with climate change. The research aimed to analyse how interactions between jurisdictional scales, urban stakeholders and policies promoting synergies affect adaptation processes in cities using overheating policies in London as an example. Understanding how these interactions affect policy implementation can ensure
This master thesis explores the possibilities of social robot adoption in the hotel industry. Social robots represent a new product group, a radical innovation, that has yet not seen commercialization in the hotel industry in Sweden. Furthermore, previous research has requested studies that determine success factors for social robot adoption in specific markets. This thesis therefore investigates
This research investigates short-term management fixation to meet performance thresholds through real earnings management. Specifically, we examine management decision-making regarding the trade-off between short-term profitability and R&D’s long-term benefits in Nordic firms. Building on established economic and institutional frameworks, along with the most relevant studies in the field, this
Food production is a critical component of global livelihoods and economic revenue. However, storing harvested food presents challenges in minimizing post-harvest losses. Among various methods, food drying has emerged as a popular technique for preserving food during off-seasons. The Solar Food project aims to design an affordable solar-powered food dryer that enhances the drying process and main

Seagrasses are important components of marine ecosystem. They are a primary food source for many organisms and provide shelter and nursery areas for many more. Also they stabilize sediments and act as a natural barrier against coastal erosion. But despite their valuable rule, Seagrasses are facing large threats because of human development. The stresses caused by human activities like trawling and
The PHENIX experiment at the Relativistic Heavy Ion Collider has measured the differential cross section of φ(1020)-meson production at forward rapidity in p+p collisions at s=510 GeV via the dimuon decay channel. The partial cross section in the rapidity and pT ranges 1.2
In this paper we describe field investigations of leachate recirculation at a bioreactor landfill using geoelectrical imagining technique (i.e., electrical resistivity) combined with a tracer test. The use of geoelectrical imagining techniques is an established practice for environmental investigations and monitoring of various landfill processes and in recent years also the bioreactor landfill co
IKEA is currently in the progress of integrating Business Process Management (BPM) into the current functional organization. In order to investigate how to increase the accuracy of the capacity planning, IKEA saw a need of examining the processes connected to Plan & Secure Capacity, a sub process to the main process Supplying. The purpose of this master thesis is to by using Network Planning m
Populärvetenskaplig sammanfattning: Frågan om jordens ålder fick sitt svar först vid 1900-talets början, då upptäckten gjordes att uran sönderfaller till bly med bestämd hastighet. Genom att mäta blyisotoper i uranhaltiga mineral kunde man räkna baklänges och se hur lång tid som krävts för att den uppmätta mängden bly skulle bildas. Samma typ av beräkningar gjorda på mineralet zirkon (ZrSiO2) är i

[utdrag] Allt sedan krigets första dagar har det funnits de som sett det organiserade dödandet som ett sätt att tillförskansa sig personlig rikedom. De har slagits för nationella arméer, de har slagit för gerillagrupper, i uppror, i kriminella uppgörelser och på internationella uppdrag. Deras roll och anseende har skiftat med tiden. Med ett samlingsnamn har vi valt att kalla dem legosoldater. Le
This essay contains an analysis of the Root Causes of the Post Election Violence that broke out in Kenya after the 2007 election. Authors of the action plans for prevention of similar situations need to make assumptions of causal relations in order to take the right measures and make the right changes. The main focus of this paper lies on the assumptions on causal mechanisms of those phenomena tha
INTRODUCTION: Cytotechnologists have long been central to cervical cancer screening, although their education and job responsibilities differ markedly across countries. The adoption of primary HPV testing has substantially reshaped cytotechnology workforce needs and professional roles. In Sweden, however, no comprehensive overview of these changes exists. This study therefore examined cytotechnolo
Objectives Structural valve deterioration is an inherent limitation of bioprosthetic valves; however, the time it takes to develop varies depending on the valve model. The Sorin Soprano aortic bioprosthetic valve (Sorin Group/LivaNova, Milan, Italy) lacks reported long-term results. This study aims to establish the long-term durability of this bioprosthetic valve in a nationwide cohort. Methods Al
The field of general-purpose robotics has recently embraced powerful probabilistic diffusion-based models to learn the complex embodiment behaviours. However, existing models often come with significant trade-offs, namely high computational costs for inference and a fundamental inability to quantify output uncertainty. We introduce Normalizing Flows Policy (NF-P), a conditional normalizing flow-ba
