Bioethanol 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

Följderna av narkotikamissbruk kostar samhället stora summor pengar varje år. Att beräkna den exakta storleken på dessa summor är omöjligt, eftersom stora delar av den narkotikarelaterade verksamheten är olaglig. De kostnadsberäkningar man kan göra blir ungefärliga uppskattningar. Ändå är det viktigt att försöka, eftersom den kunskap man har om kostnaderna för narkotikamissbrukets konsekvenser utg

BackgroundChronic pain is a highly prevalent disease, leading to high health care costs, impaired productivity, and decreased quality of life. An artificial intelligence (AI)-powered, digital tool for self-management (PaindrainerTM) has been shown to be an effective treatment in chronic pain and may have potential to reduce the burden on costs and quality of life.ObjectiveThe objective of this stu

Throughout history, people have always been faced by difficulties regarding their physical conditions. Vision of sight is no different and poor eyesight has certainly hindered a lot of people from achieving their goals in life. To this day, this still holds true and many people around the globe are affected by some sort of visual impairment. The purpose of this study is to describe and to determ

The aim of this study is to estimate the net economic cost of all suicides that occurred in Sweden in 2015. The purpose is to provide a more thorough assessment of this cost compared to previous research. Based on the theoretical and methodological framework of so called Cost of Illness (COI) studies, previous research, as well as original solutions, this study estimates direct costs, indirect cos

This dissertation utilizes a new dataset on the belongings of early modern households, gathered from southern Sweden, to map the development of wealth and material living standards over the course of the early modern period. Together, the four papers making up the main part of the dissertation depicts a significantly more economically dynamic early modern period – especially eighteenth century – tThis dissertation utilizes a new dataset on the belongings of early modern households, gathered from southern Sweden, to map the development of wealth and material living standards over the course of the early modern period.

Question: Considering ecological factors and life history, how easy is it for sexual reproduction (as a strategy) to invade and persist in a population where all individuals are reproducing asexually? Mathematical method: We use a population growth equation that despite its simplicity captures several relevant ecological parameters: age-specific survival, differential birth rates, as well as both

We consider general prepare-and-measure scenarios in which Alice can transmit qubit states to Bob, who can perform general measurements in the form of positive operator-valued measures (POVMs). We show that the statistics obtained in any such quantum protocol can be simulated by the purely classical means of shared randomness and two bits of communication. Furthermore, we prove that two bits of co

The epidemic of type 2 diabetes mellitus (T2DM) on a global scale is a matter of concern, not only from a public health perspective, but also with consideration of societal costs. The increased call on health care resources to treat and monitor T2DM and its complications could put a heavy burden on national health care systems and financing. An important contributing factor for development of T2DM

This paper explores a new method for evaluating the cost of verifying a contract. We relate these costs to the number of computations an algorithm needs to check that a contract satisfies certain criteria. Two different criteria that facilitate enforcement of the contract are studied. Our findings indicate bounds on the computational costs as the size of the contract grows. If each computation cos

This case explores the rise and challenges of Vässla, a Swedish electric micromobility startup that positioned itself as a premium, sustainable alternative to gas-powered scooters. Despite strong brand differentiation, consumer demand, and initial success, Vässla faced operational difficulties and financial instability. Set in 2019, this case challenges students to assess whether Vässla’s brand st

This thesis investigates how students navigate interpersonal and professional relationships in the context of neoliberal rationality and Web 2.0 digital infrastructures. Focusing on self-marketization practices and the conflict between online personas and real identities, the study draws on qualitative data from interviews and focus groups with university students aged 20–35. Using a dual theoreti
