Idag har det blivit otroligt viktigt med ett miljömässigt ansvarstagande, speciellt vad gäller elproduktion. Här presenteras ett arbete där prestandabedömningen av dagens mest termodynamiskt effektiva fossila kraftverk, kombikraftverk, revolutioneras.Power production has a vital role in the functioning of society and will have a major part in the future of environmental and economical sustainability. Therefore, efficiencies of power plants are always a subject to improvements in order to utilise resources as efficient as possible. A Combined Cycle, combining a gas turbine topping cycle and a steam turbine bottoming cycle, is a widely used conf

This thesis addresses the lived experiencesof immigrant detention in Sweden, in the light of Sweden’s ongoing expansion of its detention capacity, and increasingly deportation focused migration policy.

Påverkar det vort transportval när vi bekymrar oss om klimatet? När vanliga människor oroar sig om klimatförändringen har det betydning för hur dom uppfattar sin transport i vardagen. Klimatbekymringen spelar i denna studie ingen avgörande roll för om folk väljer bil, bus eller cykel. Men ändå påverkas t. ex. synen på olika transportformer och känslan för vad som är ett individuellt ansvar. KlimaCitizens concerned about climate change could represent a potential for changes in everyday travel behaviour in a less carbon intensive way, or even put public pressure on governmental decisions to mitigate climate change emissions from the transport sector. Situated in the context of rural residents’ everyday life in Denmark, this study explores how the role of climate change concerns within resi

The unfavourable social and economic situation of Roma in the EU has been on debate for decades. There are several efforts at the national and international level to improve the social and economic situation of Roma as many of them still face deep poverty and discrimination. There are more than 10 million Roma across the EU and they are recognised as one of the largest ethnic groups in the region.

Mänsklighetens intresse för rymden och allt bortom vår värld har alltid varit ett faktum. Raketer har skjutits upp i det svarta sedan 1940-talet och utvecklingen av rymdutrustning går ständigt framåt med ny teknik som konstant tänjer på gränserna för vad vi trodde var möjligt. Dock leder nya tankar och idéer till ökad resursefterfrågan, särskilt i de tidigare designstadien. Därför behövs metoder fEarly designs are often based on rough estimations and assumptions. Such is also the case when designing space turbines that power rocket engine fuel pumps which generally have obscure performance and size requirements. Often times, this leads to unique, single-use designs. This complicates and restricts the amount of possible testing. To aid in this early design process and to help predict turbin

This master thesis in social anthropology, is based on fieldwork, conducted in the peruvian village Andamarca, in the region of Ayacucho, from February to April 2018. I have studied the special kind of folk music, called huayno, in order to establish its role in the local community. The inhabitants find themselves living in a vulnerable state, based on a violent history and political oppression. T

In recent years sustainable investment has increased enormously, and firms that are considered to have high social responsibility has gained interest from investors. However, if these firms have higher financial performance or not is still unclear, and researchers still have split opinions on the relationship. The purpose of this research is to analyze this relationship, with data collected from t

I den här uppsatsen undersöks generella effektiviseringar i svenska kommuner. Med generella effektiviseringar avses när förvaltningar eller verksamheter åläggs generella sparkrav utan att kraven på verksamhetens kvalitet eller vad den ska utföra sänks. Frågeställningarna har varit: • Med vilka argument har generella effektiviseringar genomförts av kommuner? • Hur är de kommunalt genomförda genere

Påverkar probiotika tarmfloran hos barn med celiaki? Celiaki är en autoimmun sjukdom som beror av både arv och miljö. En faktor som kan påverka är tarmfloran. I det här arbetet undersöktes hur tarmfloran påverkades när barn med risk för celiaki behandlades med antingen probiotika eller placebo. För att bättre förstå varför en del barn drabbas av autoimmuna sjukdomar som diabetes och celiaki haCeliac disease is an autoimmune disease triggered by gluten intake. The disease has both a genetic component and an environmental component. Celiac disease is often associated with dysbiosis and lower diversity of the gut microbiota. In this study a group of 3-year-olds susceptible to celiac disease were enrolled in a double-blind placebo-controlled randomized trial using a combination of two prob

This paper exploits the adoption of Single Spine Pay Policy (SSPP) as a natural experiment to investigate the potency of wage policies in addressing the pay differentials between the public and private sector in Africa. The Government of Ghana in 2010, implemented the SSPP to tackle the long-standing wage gap between the public and private sector and consequently improve productivity in the public

Sökmotoroptimering (SEO) är ett sätt att arbeta på som förbättrar ens hemsidas ranking hos sökmotorer. Teorier om hur man ska jobba med det och varför man ska göra det har beskrivits i tidigare litteratur. Trots detta är det ett stort antal företag som väljer att inte arbeta med det. Denna uppsats syftar till att undersöka varför små och medelstora företag inte arbetar med SEO. Detta görs i en kom

Upplevelsen av en värmebölja och förberedelser inför en varmare framtid Det allt varmare klimatet innebär att värmeböljor kommer att bli vanligare i Sverige. Väldigt varmt väder utgör ett direkt hot mot människors hälsa, men tas detta hot på tillräckligt stort allvar i samhället? Den globala uppvärmningen påverkar människors hälsa negativt. Värmeexponering under extremt varma perioder utgör en cAs global temperatures rise, adverse health effects due to heat exposure are an increasingly pressing issue, particularly threatening to the health of elderly people. Mitigating these threats requires a dynamic climate adaptation system embedding a variety of measures. Ideally, such a system incorporates the coping strategies and experiences of the vulnerable themselves in a well-developed strateg

The automation of work tasks has been of high interest for over a century, where different technologies have been developed to serve this purpose. Robotic Process Automation (RPA) is one of these technologies, which automates the execution of monotonous and repetitive work tasks previously performed by humans. As a consequence, the employee whose job consists of these work tasks might perceive eff

The ability to navigate from breeding sites and wintering grounds has fascinated numerous avian studies examining the bird orientation performances. The migratory avian navigational toolbox consist of route- and map-based orientation, non-compass, vector and compass orientation. The compass orientation consist of celestial and geomagnetic cues, which are divided into the three main compasses known

Traditional mean-variance optimization of portfolios has received much criticism due to its inability to account for higher order moments and non-quadratic utility. In this thesis, the topic of portfolio optimization is studied using the Atkinson index with CRRA utility. We construct Atkinson-efficient portfolios using computer-generated data in Monte Carlo simulations, as well as using financial
