Plastkonsumtionen har ökat markant över tid och har utvecklats till ett viktigt material i dagens samhälle, men med utmaningen att råvaran främst kommer från fossila källor. Användningen av plast är i linje med den linjära ekonomin och den så kallade slit-och-släng-kulturen, vilket bidrar till felaktig hantering av plastavfall och en ineffektiv användning av resurser. Detta kräver en övergång till​​The consumption of plastic has significantly increased over time and has emerged as a vital material in contemporary society, primarily derived from fossil fuels. Use of plastic aligns with the linear economy of “take, make, dispose”, which contributes to mishandling of plastic waste and an ineffective use of resources. This calls for a shift towards a circular economy, advocating for the princi

Intrafractional prostate motion during external beam radiotherapy of prostate tumors has been reported as a limiting factor in accurate treatment delivery. Technology for real-time image-guided radiotherapy has been introduced for tracking and for compensating prostate motion during treatment and could allow for reduced target margins. This project investigated the geometrical accuracy of Radixact

The knee menisci distribute and dampen mechanical loads. Vulnerability to injury and disease of the meniscus is a global issue, particularly concerning osteoarthritis. The connection between the breakdown of meniscal tissue and its mechanical response is not entirely understood. This thesis seeks to contribute to filling this knowledge gap by developing and implementing a digital volume correlatio

Title Physiotherapeutic interventions for the treatment of shoulder dysfunction after neck dissection – a literature review Background Neck dissection is a surgical procedure used in treatment of head and neck cancer. Shoulder dysfunction and pain are common consequences due to this procedure. The physiotherapeutic treatment of the shoulder is both important to prevent adhesive capsulitis and res

With 10,5% women in parliament, Myanmar ranks number 157 out of 193 countries on the rate of women in parliament. This thesis aims at investigating the gendered institutions that influence women’s descriptive representation in politics through a case study on political recruitment within the Democratic Party for a New Society, DPNS, and their youth wing Youth for a New Society. The main research q

As of today, there are no binding obligations under international human rights law for companies. Therefore, the UNGPs and the OECD Guidelines has emerged as soft law instruments which explains social and legal expectations on states and business in regards of human rights. According to the principles, states has the primary role in protecting human rights while business should respect human right

This thesis aims to investigate Sida’s view on gender integration and gender (in)equality as well as how this understanding may affect the way Sida works to promote gender equality globally. Since gender integration is the main method for increasing gender equality at Sida The plan for gender integration at Sida 2015-2018, as well as the partial report on this plan, is analysed in to reach this ai

Oats have been gaining huge popularity in the past three decades, due to its well-known positive effects in serum cholesterol levels, glucose homeostasis and insulinemia. A growing body of evidence shows a link between obesity, metabolic dysfunctions and gut microbiota composition. The main objective of the project is to develop an oat bran and milk based fiber-rich beverage and an oat based yogur

White-light spectra of different crystals, based on 1030-nm intense pump pulses have been investigated in order to derive a near-infrared seed for mid-infrared generation. Among ten crystals, YAG (yttrium aluminium garnet), KGW (potassium gadolinium tungstate) and YVO4 (yttrium orthovanadate) exhibit the most suitable properties for supercontinuum generation with high efficiency for spectral broad

The European Spallation Source is currently under construction in Lund, Sweden. Consisting of a linear accelerator delivering an unprecedented 5 MW proton beam to the spallation source, i.e. a rotating Tungsten disk, it will deliver high-flux neutron beams to multiple beamlines at which scientific experiments will be conducted in many scientific disciplines. To simulate the proton beam and for cr

The concept of industrial symbiosis (IS) provides practical solutions for resource efficiency and low-carbon development. The IS represents a collective, multi-industrial approach for companies to improve their economic and environmental performance through the sharing of heat, electricity, water, by-products, information, and reuse of waste. The main challenges to IS emergence include a long dura

The issue of pharmaceutical pollution has recently gained attention on the international political agenda as several actors have raised concern for its negative impact on ecosystems, human health, and livelihoods in emerging economies where an increasing share of the pharmaceutical production is located due to the cheaper labor and less stringent environmental regulations. In 2019, the OECD publis

Forced air convection systems are the most preferred design of choice in many of the industrial-scale convection ovens. In this study, experimental investigation on convective heat transfer and mass transfer within a forced air convection oven was performed at different oven temperatures (100℃, 110℃ and 120℃) and at flow velocity (2 m/s, 3 m/s and 4 m/s) using potato slices (10*10*60 mm) as model

In this thesis, a study is made into relative positioning and control systems for flying wing Micro Aerial Vehicles (MAVs) intended to be used by the Swedish Sea Rescue Society (SSRS) for the purpose of providing assistance during sea rescue missions. The particular scenario of interest is robust relative positioning to be used for autonomous landing of a MAV on a boat at the end of a rescue missi

Inventory control is a subject that impacts more or less every section of most businesses, hence companies today view it as a crucial problem of strategic importance (Axsäter, 2015). Managing inventory is a complex task which can be made even more complex by considering multiple items interacting with each other throughout the supply network. This master thesis attempts to show, through a case stu

In an era of globalization, international legal frameworks and vigorous international politics, we cannot refrain from hearing about the extensive health crisis of the developing world. HIV/AIDS, Malaria and drug resistant tuberculosis are only a few of the widespread disease which appear almost surreal to the citizens of the industrial world. The debates and discussions regarding the importance o

Idag behandlas de flesta patienter som diagnostiserats med gliom, en otäck hjärntumör, med fotoner producerade i en linjäraccelerator på någon av landets strålbehandlingskliniker. Tumören växer inuti hjärnan på ett mycket aggressivt sätt, vilket gör den nästan omöjlig att bota. Det normala är att strålningen kombineras med cellgifter och kirurgi för att ge patienten så lång tid som är möjligt, tilIncreased accuracy in patient dosimetry in BNCT is needed. This need for more accurate individual patient dose estimations initiated this project at the Swedish BNCT facility at Studsvik. One possible way to achieve this is to use an HPGe detector. This project involves the complete construction and testing of such a system in a treatment representative environment.The system builds on an ORTEC GM
