Abstract Oil rich states all over the world share a common feature. They are less likely than other states, depending on other resources, to be ruled democratically. In this essay Saudi Arabia has been studied with the purpose of trying to find which mechanisms that lie behind why oil rich states do not have institutions or institutional change that promotes democracy. Saudi Arabia has the world
In this paper, we study event-based PID control from an optimal stochastic control perspective. The purpose is to better understand what implementation features are critical for achieving good event-based PID performance. For this end, we formulate an LQG control design problem for a double integrator process with an integral disturbance, where the solution is an ideal PID controller. We then cons
A closely-packed ultrawideband (UWB) multiple- input multiple-output (MIMO)/diversity antenna (of two elements) with a size of 25 mm by 40 mm is proposed for USB dongle applications. Wideband isolation can be achieved through the different patterns and polarizations of the two antenna elements. Moreover, the slot that is formed between the monopole and the ground plane of the half slot antenna is
The aim of this study is to utilize a qualitative content analysis in order to examine the stories of twelve childfree women featured in the anthology "Nobody's Mother" [translated title] (2013). When designing this study we have focused on the reasons to why these women have chosen not to have any children and how they experience social expectations related to motherhood. Swedish we
Synthetic biology, a branch of the life sciences, can be summarized as the deliberate attempt to design living organisms. It is an emerging technoscience and a potential platform technology portrayed as possibly the next industrial revolution. This thesis is an inquiry into synthetic biology; an exploration based on observations in text. An explorative tool is the question: What is synthetic biolo
The purpose of this Essay is to study whether Swedish Army Officers of today are less prepared for an armed conflict than their older colleagues. The study is a text analysis of Meir Finkel’s theory on Cognitive and Command Flexibility, Swedish military Doctrines and other relevant documents. A research report put together by Swedish Defence Research Agency examining the process of career developm
Köp av sexuella tjänster har sedan 1999 varit förbjudet i Sverige. I samband med att förbudet skulle införas föreslogs att både köp och försäljning av sexuella tjänster skulle förbjudas, men efter omfattande kritik var det enbart köp som slutligen kriminaliserades. Kritiken grundades till stor del på att säljaren ofta utnyttjades av köparen och befann sig i en utsatt position vid sexköp. År 2018 Purchase of sexual services has been illegal in Sweden since 1999. Prior to the criminalization, it was suggested that both purchase and sale of sexual services should be criminalized, but after extensive criticism, only purchase was ultimately made illegal. The criticism was largely based on the fact that the seller often was exploited by the buyer and in a vulnerable position during purchase of
This thesis investigates the feasibility of integrating Powdered Activated Carbon (PAC) in to chemical treatment in combination with disc filtration of tertiary wastewater. Jar and tube tests have been performed, where the suspension was filtered through a 10 μm disc filter from Hydrotech Veolia Water Technologies. The effluent has been analyzed for total phosphorus (TP), total suspended solids (T

Although that the textile-industry is considered the world’s second most climate affecting industry, consumption seems to never cease. The Swedish start-up project Streamateria provides new opportunities through a distributed production-line that offers bio-degradable garments through 3D-printing technology, with the ambition to meet consumer demand for "fast fashion" The aim of the stu
Författare: Jacob Johannisson och Marcus Johansson Handledare: Jon Bertilsson Syfte: Syftet med denna uppsats är att öka förståelsen för hur sociala medier påverkar relationsbyggandet mellan företag inom business-to-business och på så sätt bidra till dagens teorier och forskning kring relationsmarknadsföring. Metod: För att samla in empiri och kunna svara på frågeställningen har denna uppsats eAuthors: Jacob Johannisson and Marcus Johansson Advisor: Jon Bertilsson Purpose: The purpose of this paper is to enhance the understanding of how social media affects relationship building between business-to-business companies and thereby contribute to current theories and research within the relationship marketing area. Methodology: To enable us to collect empirical data and give an answer to
We investigated how the legacy of warming and summer-drought affected microbial communities in five different replicated long-term (>10 years) field-experiments across Europe (EU-FP7 INCREASE infrastructure). To focus explicitly on legacy effects (i.e. indirect rather than direct effects of the environmental factors), we measured microbial variables under the same moisture and temperature in a bri
The Research Training Network “Women in European Universities” focuses on career opportunities of women in higher education in seven European countries (Austria, France, Germany, Poland, Spain, Sweden and the United Kingdom). Within the frame of this network different aspects of career perspectives of women – and also men – are investigated. In a first working step a context analysis was conducted
Popular Abstract in Undetermined Denne afhandling præsenterer en ny udlæsnings metode udviklet til cantileverbaserede sensorer. Cantilevere er tynde vipper, der er fastgjorte i den ene ende, og som igennem de seneste ti °ar har vist sig at være en interessant ny type bio/kemisk sensor. Den specifikke genkendelse af et kemikalie viser sig ved at cantileveren bøjer som følge af det skabte overfladesThis thesis presents a novel read-out method developed for cantilever-based sensors. Cantilevers are thin beams clamped at one end and during the last 10 years they have emerged as an interesting new type of bio/chemical sensor. The specific recognition of a chemical manifests itself as a bending of the cantilever from the generated surface stress. Conventionally the read-out used for this type of
In this paper, the transversal diffusion coefficient D of CO2 dissolved molecules through the wall of a hydrated cellulose fiber was approached, from the liquid bulk diffusion coefficient of CO2 dissolved molecules modified by an obstruction factor. The porous network between the cellulose microfibrils of the fiber wall was assumed being saturated with liquid. We retrieved information from previou
Extn. of lignin from kraft black liquor is one method of lowering the large energy surplus in pulp mills. The lignin can be used as a bio-fuel to replace fossil fuels in heat or power generation, and the lignin-depleted black liquor can be reused in the cooking operation. As kraft black liquor lignin has a fairly high mol. wt., ultrafiltration can be used to selectively fractionate lignin from coo
Popular Abstract in English In our current world, the exponential growth in demand for smaller and faster devices leads to the fact that we will eventually face the problem that traditional semiconductor technologies will reach their limitation in terms of size and speed. Humanity's consciousness to tackle the global ecological issues in the next decade, will demand the substitution of all non-reuThe work presented in this thesis addresses the investigation of the electronic, magnetic, and structural properties of late transition metal complexes supported on various surfaces. The research is aimed at studying the interaction between the molecules and the support, together with the intermolecular interaction. This knowledge is essential e.g. for the development of organic molecule-based dev
