The part-load behaviour of combined cycle power plants (CCPP) equipped with post-combustion CO2 capture is analyzed. Different CCPP configurations are compared, including single-, dual- or triple-pressure level steam generators. The gas turbine is a single shaft unit using the variable guide vanes and fuel flow to control the load. The 90% CO2 capture is achieved using monoethanolamine (MEA 30%wt)
Background Abiraterone acetate (AA) prolongs survival in metastatic castration-resistant prostate cancer (mCRPC) patients. To measure treatment response accurately in bone, quantitative methods are needed. The Bone Scan Index (BSI), a prognostic imaging biomarker, reflects the tumour burden in bone as a percentage of the total skeletal mass calculated from bone scintigraphy. Objective To evaluate
Denna avhandling studerar faktorer som påverkar rekryterare då de skall välja bland jobbsökande med olika etnisk bakgrund. Generellt förväntades att de sökandes etnicitet skulle påverka rekryterares val och deras uppfattning om vad som är viktigt att ta fasta på hos en arbetssökande person, och att detta kan ske i olika faser av rekryteringsprocessen.Studie 1 visade att företagsnormer påverkar rekThe present thesis aimed to study different factors influencing recruiters when recruiting from an applicant pool with applicants from an ethnic ingroup and outgroup. Ethnicity was predicted to influence recruiters’ perception and behaviour in different phases during recruitment. Study I demonstrated that company norms affect recruiters’ perception of what an employee should be like. Company norms

(2) How does individual traits and the built environment affec
Penningtvätt har länge varit ett uppmärksammat problem, men inte förrän på senare år, särskilt efter den 11 september 2001 och terroristattackerna i USA har stora krafttag gjort att bekämpningen av problemet kommit igång. Bekämpningen och förhindrandet av penningtvätt och finansiering av terrorism är även viktigt utifrån ett större perspektiv. Om man kan strypa finanserna för kriminell verksamhet,Money laundering has for a long time been an acknowledged problem, now more than ever. Especially after 9/11 2001 and the terrorist attacks in the USA, joint efforts have made combating the problem a serious matter. Combating and prevention of money laundering and terrorism financing is also important from a larger perspective. If you can close off finances of criminal activity, you are one step c
2005 släppte Förenta Nationernas folkrättskommission rapporten "Fragmentation of International Law: Difficulties arising from the diversification and expansion of International Law". Även om fragmenteringen av folkrätten hade varit ett diskussionsämne långt före 2005 fick rapporten verkligen debatten ta fart och fragmentering att bli en av de mest omdebatterade frågorna under senare år bIn 2005 the United Nations International Law Commission released the report Fragmentation of International Law: Difficulties arising from the diversification and expansion of International Law. Although fragmentation of international law had been a topic of discussion long before 2005 the report really made the debate take off, becoming one of the most debated issues in recent years among internat
Perovskite research has quickly gone from non-existent to one of the biggest reseach areas in Photo- voltaics. There are still many questions to be solved regarding the stability, environmental impact, reproducible large area devices, efficiency and module fabrication cost of Perovskite Solar Cells, PSCs, before commercial up-scaling. Scientists all over the world are working towards solutions and
Purpose: In this study, we examine the data from Chinese companies to test the relationship between cash flow and investment. While a wide assortment of previous research has examined the relationship between cash flow and investment, they have largely focused on empirical analysis from an US or a Western perspective. But, to date, little attention has been paid to such relationship using empirica
Sweden’s substantial building stock from the million programs is in need of renovations. These residential buildings were built without major attention to energy demand or architectural aesthetics. Until now, property owners have hesitated to carry out energy renovations due to the investment cost. The aim of this master thesis was to propose an energy-efficient renovation procedure whilst takin
Over recent decades, use of insecticides to protect plants from pests and harmful insects have increased manyfold. Neonicotinoid insecticides, such as Imidacloprid (IMI) acts as partial agonists on nicotinic acetylcholine receptors which are widely present in both the central and peripheral nervous system of insects. Pollinators like Eristalis tenax are frequently exposed to these pesticides but h
Preterm birth is a leading cause for birth complications and neonatal mortality in the world. It remains difficult to predict whether a preterm birth will occur, which hinders the possible use of prevention treatments. This thesis investigates the use of machine learning models in the prediction of spontaneous preterm birth. In addition, possible heterogeneous performance of these models among dif
The negative impacts of surface ozone (O(3)) on vegetation are determined by external exposure, leaf gas exchange and plant antioxidant defence capacity, all dependent on climate and CO(2) concentrations. In this study the influence of climate change on simulated stomatal O(3) uptake of a generic crop and a generic deciduous tree at ten European sites was investigated, using the LRTAP Mapping Manu
Phase behavior and structural features were investigated for "complex salts", consisting of the cationic hexadecyltrimethylammonium (CTA) surfactant with polyacrylate (PA(n), n = 30 or 6000) counterions, mixed with water and different n-alcohols (ethanol, butanol, hexanol, octanol, and decanol). The liquid crystalline structures formed were identified by small-angle X-ray scattering measurements,
To identify previously unknown genetic loci associated with fasting glucose concentrations, we examined the leading association signals in ten genome-wide association scans involving a total of 36,610 individuals of European descent. Variants in the gene encoding melatonin receptor 1B (MTNR1B) were consistently associated with fasting glucose across all ten studies. The strongest signal was observ
I tider av instabilitet och snabba förändringar krävs det av organisationer att snabbt kunna ställa om till nya förutsättningar för att kunna säkra sin överlevnad. Kreativitet har föreslagits vara en viktig komponent för att kunna göra detta möjligt. För att kreativitet ska kunna blomstra på arbetsplatser krävs det att vissa förutsättningar är uppfyllda. I denna studie var syftet att ta reda på omIn times of uncertainty and rapid changes it is crucial for organizations to be able to adjust to new circumstances in order to secure their survival. Creativity has been suggested as an important component in making this possible. In order for creativity to flourish in the workplace certain conditions need to be met. In this study the aim was to find out whether group personality, aggregated indi
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

Purpose: In an era of personalized oncology where the aim is to give every patient the right treatment at the right time an area of promising research is emerging called radiomics, or quantitative image analysis. The main underlying hypothesis is that pathophysiological information can be found in image texture not visible to the bare eye that can improve diagnosis, treatment adaption or be linked
Molten salt applications are challenging from a material perspective. This degree project was carried out at Alfa Laval to give them a better understanding of the corrosion of solar salt on the standard heat exchanger material stainless steel 321. Similar tests have previously been performed externally. By developing test methods for in-house corrosion testing time and money can be saved. In thi
Loss of soil organic carbon (SOC) from farmland is a key threat to the capacity of soils to provide ecosystem services and exacerbates climate change. In alignment with a published protocol, we conducted a review and meta-analysis of time series of SOC measurements in long-term agricultural experiments to study absolute SOC changes under different agricultural management regimes. Our results show
