Background: The commercialization of second-generation bioethanol has not been realized due to several factors, including poor biomass utilization and high production cost. It is generally accepted that the most important parameters in reducing the production cost are the ethanol yield and the ethanol concentration in the fermentation broth. Agricultural residues contain large amounts of hemicellu
Crohn's disease (CD) and ulcerative colitis (UC) are chronic inflammatory bowel diseases that have a remitting, relapsing nature. During relapse, they are treated with drugs and surgery. The present study was based on individual data from patients diagnosed with CD or UC at Herlev University Hospital, Copenhagen, Denmark, during 1991 to 1993. The data were aggregated over calendar years; for each
Spectroscopic Photoemission and Low Energy Electron Microscopy (SPELEEM) is a very powerful and diverse microscopy technique for the investigation of surfaces, interfaces, buried layers and nanoscale objects like nanoparticles and nanowires. The many significant results from photoemission Electron microscopy (PEEM) in recent years are linked with the exploitation of advanced light sources such as
BACKGROUND-Multiple laboratory tests are used in the diagnosis and management of patients with diabetes mellitus. The quality of the scientific evidence supporting the use of these assays varies substantially. APPROACH-An expert committee compiled evidence-based recommendations for the use of laboratory analysis in patients with diabetes. A new system was developed to grade the overall quality of
Popular Abstract in Swedish Ekonomin och välfärden är starkt beroende av tillförlitlig transport och energiförsörjningsteknologi. En stor del av denna teknik bygger på användandet av förbränningsmotorer. Då dessa till antalet är så stort utgör de tillsammans en stor miljöbelastning. Därför måste det läggas stora resurser på förbättrad motorstyrning och avgasrening. En av restprodukterna från förBoth the global economy and the society in general are dependent on the availability of reliable transportation. Most transportation technology involves the use of internal combustion engines in one way or another. Because of the large numbers of internal combustion engines in use around the world, their emissions have a significant environmental impact. Therefore, considerable efforts have been i
Background: There is currently a steady increase in the use of wood-based fuels for heat and power production in Sweden. A major proportion of these fuels could serve as feedstock for ethanol production. In this study various options for the utilization of the solid residue formed during ethanol production from spruce, such as the production of pellets, electricity and heat for district heating, w
Exposure to some pesticides and persistent organic pollutants (POPs) has been indicated to be a risk factor for non-Hodgkin's lymphoma (NHL). Epstein-Barr virus (EBV) has been associated with some subgroups of NHL. In a previous study we found an interaction between high concentrations of some POPs and titres of antibodies to EBV early antigen (EA IgG) in relation to NHL. In the present study we m
The introduction of L-DOPA pharmacotherapy revolutionized the treatment of Parkinson’s disease close to fifty years ago. Before the discovery of dopamine as a neurotransmitter and its involvement in the disease, these patients had very little aid from medication and were bound to a life without movement. The dopamine neurons in the midbrain are a key player in the circuitry that is responsible for
In the present study, a simple and reliable antioxidant screening technique based on lactate dehydrogenase (LDH) oxidation by Cu2+-mediated Fenton's reaction has successfully been developed. Oxidation of LDH by hydroxyl radical consequently leads to enzymatic inactivation, while addition of antioxidants can protect and regain enzyme activity. This method demonstrated a high feasibility on detectin
This thesis covers the design of a wideband, flexible front end for LTE and LTE-A in a 65 nm CMOS process. A topology with global frequency translational feedback is investigated and a harmonic rejection mixer is implemented. To compensate for parasitics at the RF input, a variable phase shift is used in the global feedback to improve input matching and prevent loss of noise performance. Combinati
This thesis investigates the intertwining of corporate social responsibility (CSR) discourse and the European Union's strategy for sustainable and circular textiles through a single case study and critical frame analysis (CFA). By doing this, concurring discourse between corporations and the institutions aimed at governing them can be problematised. Derived from conventional and contemporary C
In crisis-hit Greece, there have been an unprecedented rise of grassroots self-help initiatives for the last three to four years, and the whole phenomenon has come to be known as the quest for social and solidarity economy. With the consolidation of political and economic power in today’s capitalist market economy, the social and solidarity movement in Greece has been seeking for a way forward to
The purpose of this study is to conduct the Life Cycle Assessment of IKEA’s two Sofa products and provide recommendations for reducing the overall carbon footprints. Different phases of supply chains are included in the scope of this study, i.e., selection of raw materials, their acquisition, production phase, and transportation of final product to market regions. The benefit of the study is that
På grund av den snabba förändringen i det audiovisuella medielandskapet får konsumenterna och särskilt minderåriga alltmer tillgång till medieinnehåll via andra digitala plattformar än traditionella TV och video on demand tjänster. Av den anledningen är det idag mer lönsamt för företag att annonsera genom produktplacering och sponsring på plattformar för videodelning som inte regleras inom ramen fDue to the rapidly changing pace of the audiovisual media landscape, consumers and especially minors are increasingly accessing media content via other digital platforms than traditional television and on-demand services. For that reason, is it today more profitable for companies to advertise through product placement and sponsorship on video-sharing platforms which are not regulated within the sc
The master thesis seeks to develop a control system for the Crazyflie 2.0 unmanned aerial vehicle to enable aggressive and autonomous flight. For this purpose, different rigid-body models are considered, differing primarily in their parametrisation of rotation. The property of differential flatness is explored and several means of parametrising trajectories in at output space are implemented. A ne
Development of valuable products from downstream process residual biomasses and profound reduction of waste are two key components for developing a more sustainable process industry. The importance of bio-renewable feedstocks and bio-based processing techniques are also crucial in the transformation to a more sustainable and green society. Therefore focus is directed on full exploitation of seawee
PURPOSE: Our purpose for this study is to describe and analyze the problems and challenges linked to measuring performance in activities directly and indirectly related to organizational purpose. METHODOLOGY: To map the issues and challenges connected to measuring performance based on organizational purpose we have used 8 case studies divided in following categories; 2 sectors (for-profit and nonp
Utmaningar kring samarbete och effektivt utnyttjande av den tvärprofessionella kompetensen har observerats i svenska elevhälsoteam. En kommun har adresserat dessa svårigheter genom att implementera ett gemensamt ramverk, Systematiskt Tillsammans för Lärande (STfL). Syftet med föreliggande studie var att utforska hur ett sådant gemensamt ramverk upplevs av elevhälsoteamens olika professioner vad gäCollaboration and efficient use of multidisciplinary competence has been observed to be difficult in student health teams (SHT) in Sweden. One municipality has addressed these issues by implementing a common framework, Systematically Together for Learning (STfL). The aim of this study was to explore how this framework was experienced by the student health service professionals in relation to imple
Practitioners primarily utilise nonparametric methods when estimating Value-at- Risk (VaR) and Expected Shortfall (ES) for computing capital requirements. However, various researchers assert that there are issues with those estimates, particularly amidst periods of market turmoil. Academia produces novel parametric methods to estimate extreme risk measures to address these deficiencies. Neverthele
