Popular Abstract in English Modern society is still largely based on fossil resources. However, there are growing concerns about the security and cost of these resources, as well as climate change resulting from the combustion of fossil fuels. Biofuels represent renewable fuels with the potential to mitigate the adverse effects of fossil fuels, providing a more sustainable alternative. The transpBioethanol from sugarcane is a sustainable alternative to fossil fuels, and the increasing demand for fuel ethanol has prompted studies on the use of the lignocellulosic residues of sugarcane, namely bagasse and leaves, as new feedstock. This thesis describes various process designs and the economic feasibility of producing second generation (2G) ethanol from bagasse and leaves via the enzymatic r

Objective: The authors sought to clarify the sources of parent-offspring resemblance for drug abuse, alcohol use disorders, and criminal behavior, using a novel genetic-epidemiological design. Method: Using national registries, the authors identified rates of drug abuse, alcohol use disorders, and criminal behavior in 41,360 Swedish individuals born between 1960 and 1990 and raised in triparental

Contemporary advancements in miniaturization of analytical systems have advantageously fostered development, automation, and hyphenation of a variety of sample preparation techniques. Among several downscaled extraction designs, porous synthetic polymeric membranes (such as flat sheet (FS) or hollow fiber (HF)) have been utilized for membrane-based extraction, separating two aqueous phases (as in

The number of electronic devices and household appliances in everyday live has an ongoing exponential growth. The

För att undersöka nanopartiklars toxicitet finns behov av att producera väldefinierade nanopartiklar dispergerade i en kolloid suspension. Men även för andra områden så som nanomedicin finns ett behov av denna typ av lösningar. För att dispergera partiklarna i vätska används ofta ytaktiva ämnen. När dessa ämnen tillsätts adderas de på ytan av partikeln och förändrar partiklarnas yta. Då forskning To examine nanoparticle toxicity there is a need to produce defined nanoparticles dispersed in a colloidal suspension. Such a solution could also be interesting for other fields such as nano-medicine. In order to disperse the particles in the liquid there are often surfactant added to the process that alternates the surface of the particles. As the research shows that the surface of a nanoparticle

Thesis Purpose: The purpose is to explore post-acquisition tensions in a B2B firm's corporate brand identity to better understand why tensions emerge, what effect those tensions have, and lastly, how these tensions may be dealt with, if at all. Methodology: A qualitative multiple case study based on four companies with a constructionist and inductive approach has been executed in this thesis.

Sverige står inför en mycket stor investering inom järnvägen. Nya stambanor kommer att koppla samman Sveriges stora regioner och samtidigt minska restiden mellan dem. Järnvägen ses även som ett klimatsmart resealternativ, vilket bidrar till att fler väljer att ta tåget framfört till exempel flyget. Banorna kommer att utsättas för olika väder beroende på var i landet de befinner sig. Detta gör attSweden is facing big investments in railway infrastructure. The railway is seen as one of the better ways to travel to reduce the individual's carbon imprint. New mainlines will be built to interconnect the biggest cities and reduce travel time. Different parts of the line will have different kinds of weather, this results in different solutions depending on where in the country. New main line

High-order harmonic generation (HHG) is a highly nonlinear optical process in which extreme ultraviolet (XUV) radiation is generated due to the interaction of an intense laser field with atoms. This process enables the production of high harmonics, which would not be achieved with standard nonlinear media. The utilization of two-color laser fields (formed by combining a fundamental field with one

The background for this thesis is that access to sustainable electricity is part of the United Nations’ Sustainable Development Goals for 2030. In Sub- Saharan Africa, approximately 570 million people lacked access to electricity in 2022. To expand access in rural areas, solar home systems and other off-grid solar products offer affordable and accessible solutions. However, as these systems reach

Efforts to reduce energy consumption in buildings have increased with the pending impact of climate change. Heat losses through airing behaviours remain a largely unknown factor due to the variety of reasons for opening a window, making generalization difficult. Currently, an estimation of 4 kWh/m2 heated area for airing heat loss is assumed in Sweden. Additionally, the resulting airflow from open

The rapid advancements of Artificial Intelligence (AI) in recent years have reshaped markets globally, urging companies to keep up with the development to maintain competitiveness and capture first-mover advantages. Although AI adoption is increasing across sectors, it has been found that Swedish companies lag behind other countries, such as the US and China. A key challenge identified is the lack

För att utöka biogasproduktionen i Västra Götalandsregionen (VGR) kan restströmmar från jordbrukssektorn fungera som en storskalig leverantör av biomassa. Produktionen av biogas minskar beroendet av fossila bränslen och rötresten som bildas kan också återföras till jordbrukssektorn, vilket skapar ett slutet kretslopp. I detta examensarbete granskades utökningen genom en kartläggning av biogasproduTo expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. The expansion was assessed in this thesis by the investigation of

The emergence of new media technologies, particularly the Internet, has transformed communicative environments and media landscape, influencing social, cultural and political processes in our everyday life. It is claimed to contribute to the recent transnational large-scale social movements in the last decade such as the anti-globalization protests like well-known ‘Battle of Seattle’ in 1999 or th

This thesis comprises three self-contained chapters that explore how individual behavior, incentives, and institutional frameworks shape the allocation of scarce resources, with particular emphasis on healthcare markets. The first chapter examines the impact of intrinsic truth-telling preferences on consumer welfare within a priority pricing mechanism, in which individuals can gain faster access t
