The extreme ultraviolet (EUV) emission from few-times ionized tungsten atoms has been experimentally studied at the Livermore electron beam ion trap facility. The ions were produced and confined during low-energy operations of the EBIT-I electron beam ion trap. By varying the electron-beam energy from around 30-300 eV, tungsten ions in charge states expected to be abundant in tokamak divertor plas
Dynamic characterization of elastomers, i.e. laboratory testing and fitting of constitutive models, is quite complicated. The demands on the laboratory equipment and the skill of the personal handling the test equipment are high. Stationary harmonic testing is an established method for evaluating dynamic properties of elastomers. However, it is demanding experimentally when it comes to high freque
Popular Abstract in Swedish Produkter bestående av polymera material produceras i allt större omfattning. Materialen används därför i fler tillämpningar där deras specifika egenskaper kommer till användning. Materialens förmåga att modifieras för att passa en specifik tillämpning motiverar materialgruppens ökade betydelse. Idag används polymera material mer eller mindre i alla branscher t.ex. tran
It is known that pentoxifylline inhibits platelet aggregation in vitro, but the effects from pentoxifylline and its main metabolites: 3,7-dimetyl-1(5 hydroxyhexyl)xanthine (R-M1 and S-M1), 3,7-dimetyl -1(4-carboxybutyl)xanthine (M4), 3,7-dimetyl -1(3-carboxypropyl)xanthine (M5), on platelet aggregation in whole blood in vitro and in vivo have not been studied. We found that pentoxifylline, rac-M1,
Risk-taking can be either adaptive or maladaptive depending on the context, but maladaptive risk-taking sometimes has serious consequences. Understanding how self-control and other aspects of personality are related to risk-taking is important, as self-control can be improved through training. We examined how the regulative temperamental trait Activation control interacts with the reactive traits
This work presents a review of studies on the process economics of ethanol production from lignocellulosic materials published since 1996. Our objective was to identify the most costly process steps and the impact of various parameters on the fi- nal production cost, e.g. plant capacity, raw material cost, and overall product yield, as well as process configuration. The variation in estimated etha
A detailed reaction mechanism for n-heptane oxidation has been compiled and subsequently simplified. The model is based on a kinetic model for C1-C4 fuel oxidation of Hoyermann et al. [Phys. Chem. Chem. Phys., 2004, 6, 3824] and a detailed mechanism for n-heptane oxidation developed by Curran et al. [Combust. Flame, 1998, 114, 149]. The generated mechanism is kept compact by limiting the applicati
In this paper a dialectic complexity framework is presented and reflected upon. The purpose of the framework is to guide researchers and practitioners in rethinking and reframing underlying assumptions, and address how these have a possible influence and impact on researchers’ and practitioners’ processes of making sense, understanding, explaining, improving etc. aspects of different types of issu
Urban water systems are vital infrastructures in the society. The systems are widely distributed and often they are operated by different organizations. Despite a large variety of demand the system has to operate around the clock, providing a drinking water quality that is consistently good and a wastewater treatment effluent that all the time satisfies the required standard, so that the environme
The purpose of the Gramte program is to meet the needs of university students who feel that they are not mastering the grammatical terminology needed for studying linguistics or foreign languages. In all learning contexts it is important to have the adequate background knowledge. This is even more crucial when it concerns the basic concepts and terminology which will be used by the teachers during
This study examined human listeners’ ability to classify domestic cat vocalisations (meows) recorded in two different contexts; during feeding time (food related meows) and while waiting to visit a veterinarian (vet related meows). A pitch analysis showed a tendency for food related meows to have rising F0 contours, while vet related meows tended to have more falling F0 contours. 30 listeners judg
In behavioral experiments, the hawkmoth Deilephila elpenor can learn both the color and the position of artificial flowers. When very similar colors are used, moths select the correct color during the first test on a given day, thus using a stimulus strategy, but after repeated rewards, they switch to a place strategy and choose the flower in the position where they received the reward. When dissi
Scand J Caring Sci; 2009 Being in charge of life: perceptions of lifestyle among women of retirement ageAim: The aim of this study was to describe the perceptions of lifestyle among women of retirement age. Background: Women go through many transitions during their lives, which impact on their lifestyle and possibly their outlook on life. Family circumstances such as motherhood and marital status
I EU-rätten finns många versioner av ne bis in idem. De återfinns inte minst i huvudkällorna till mänskliga rättigheter i unionen: EU:s allmänna principer, stadgan om de mänskliga rättigheterna och Europakonventionen, men också i konventionen om tillämpning av Schengenavtalet och många andra regelverk. Denna uppsats berör frågan huruvida det ändå finns en enda, sammanhållen ”kärn”-förståelse av neThere are many versions of ne bis in idem in EU law. They can be found not least in the main sources of human rights of the EU legal order: the general principles of EU law, the Charter of Fundamental Rights, the European Convention on the Protection of Human Rights and Fundamental Freedoms, but also in the Convention Implementing the Schengen Agreement and many other bodies of law. This essay add
In late 18th and early 19th century Britain, a new literary genre called The Gothic was created. It heavily featured architecture and its space in order to create atmosphere and emotional impact. The rise of the Gothic novel coincided with a growing interest in Gothic architecture. In order to gain knowledge about the conception of Gothic architecture during the romantic era, this bachelorʼs thesi
The end of the Decade of Education for Sustainable Development in the present year marked a scenario to evaluate the achievement made among nations. However the success of implementation of Education for Sustainable Development (ESD) is not equal as well the information available on the subject depens on the country. The aim of the thesis is to deliver a current status and recommendations for impr
Optical aberrations are the main cause for reduced focusability and low peak intensity in laser beams. All the applications that rely on high peak power and/or small focus spot size, loose efficiency when optical aberrations are present. They can be reduced by using specially shaped optical elements, but all aberrations cannot be avoided completely. In this thesis we used a new approach for reduc
Barn som berörs av avhysning ställs i likhet med barn som drabbas av utmätning av bostad inför risken att förlora sitt hem. En trygg hemmiljö anses vara av stor vikt för barnets utveckling och främja behovet av stabilitet. Barn som befinner sig i osäkra beroendesituationer riskerar att påverkas negativt på flera plan, och upplever inte sällan stark oro och försämrat psykiskt mående. I denna uppsChildren who are affected by an eviction are, like children affected by attachment and sale of a house due to enforceable debt, faced with the risk of losing their home. A safe home environment is considered to be of great importance for the child's development and promotes the need for stability. Studies show that children subject to unsettled housing situations tend to experience grave anxie
