The ages of the oldest stars in the Galaxy indicate when star formationbegan, and provide a minimum age of the Universe. Radioactive dating ofmeteoritic material and stars relies on comparing the present abundanceratios of radioactive and stable nuclear species to the theoreticallypredicted ratios of their production. The radioisotope 232 Th (half life14 Gyr) has been used to date Galactic stars,
The Euro50 is a proposed 50m extremely large telescope for optical and infrared wavelengths. To study and predict the performance of the complete telescope system, an integrated model combining the structural model of the telescope, optics models, the control systems and the adaptive optics has been established. Wind and atmospheric disturbances are also included in the model. The integrated model
It has often been argued that the Earth is like an island in space and that its brittleness is most clearly reflected on small islands in the oceans. Easter Island, in particular, with its largely depleted resources, has been seen as a microcosmic warning about what could happen to our entire planet. However, the analogy of the Earth and islands with finite natural resources is not self-evident fr
Klimatet förändras, och det är människans aktiviteter som är orsaken. Utsläpp av växthusgaser från fossila bränslen och ohållbar markanvändning på global, regional och lokal nivå driver den pågående uppvärmningen. Hur dessa drivkrafter utvecklas framöver avgör hur stora klimatförändringarna blir på sikt. Därmed återfinns klimatproblematikens orsaker, men även dess lösningar, i hur vi bygger och ut
Thermal manikins have been used to measure thermal properties of clothing. The use of thermal manikins has made a step forward in terms of quantifying thermal properties of clothing in a 3-D manner compared with the use of hotplates for material testing. The effects of clothing properties measured on the thermal manikins under steady state (constant manikin surface temperature and constant environ
Denna uppsats behandlar frågan om när det är berättigat att kriminalisera. Utgångspunkten har varit liberal straffrättsteori och studieobjektet har varit kriminaliseringen av narkotikabruk i Sverige. I uppsatsen undersöker jag huruvida de skäl som anfördes vid kriminaliseringen av narkotikabruk kan berättiga densamma utifrån relevanta principer från den liberala straffrättsteorin. Den liberala stThis thesis concerns the issue of when it is legitimate to criminalize. The study focuses on the criminalization of drug use in Sweden and examines whether the criminalization can be justified using criteria from the liberal criminal theory. The liberal criminal theory advocates a restrictive use of criminal law and it states that criminalization as a method for preventing unwanted behaviors oug
Att bestämma omloppsbanan för en komet kan svara på många frågor omvårt solsystem, och även resten av universum. Idag använder vi oss av olika algoritmer för att preliminärt kunna beräkna omloppsbanor hos bland annat kometer, men vad krävs egentligen för att få ett någorlunda korrekt resultat? Det finns ett antal olika metoder för att bestämma omloppsbanan hos en komet, men alla är grundade i den
Instansordningsprincipen fyller en viktig funktion bland myndigheter och förvaltningsrättsdomstolarna. Detta innebär att omständigheter och material, som inte funnits med i tidigare instanser, inte får prövas i en högre instans. Målet kan i sådana fall återförvisas eller prövas på nytt utifrån nya yrkanden och omständigheter. Huruvida detta bör ske bedöms från fall till fall samt om inte särskildaCourt hierarchy principle fulfills an important function among the administrative courts. Circumstances and materials can ́t be a part of a hearing in a higher court if these things haven’t been heard in a lower court. The case can in these situations get remitted or retried according to the new claims and circumstances. Whether or not this should happen is determined on a case to case basis unles
Our theme for this bachelor’s thesis is to take a closer look at an approach used in social work that has come to create a template of sorts for how to perform daily tasks: Evidence-based practice (EBP). The broad mass of researchers and professionals in social work agree that EBP serves the common good and that the proven methods included in EBP make social work more individualized. According to
The purpose of this thesis is to put forward a method for collaboration between the fire and rescue service and the societal functions, with the aim to implement measures so that fewer people in risk groups are injured or killed in fire. Following research questions are answered in this thesis: What does the work with individualized fire safety at the rescue service and the social functions look l
Populärvetenskaplig sammanfattning: Den sedimentära enheten Brennevinsfjorden Group på Botniahalvøya, nordvästra Nordaustlandet, underlagrar diskordant en vulkanisk enhet av Grenvillisk ålder (Kapp Hansteen Group). De studier av Brennevinsfjorden Group som presenteras i detta arbete påvisar en ny stratigrafi och en bättre geografisk placering och tolkning av strukturen under basalkonglomeratet somThe Brennvinsfjorden Group of the Botniahalvøya peninsula of western Nordaustlandet unconformably underlies a Grenvillian age volcanic and volcanoclastic succession (the Kapp Hansteen Group). The studies of the Brennvinsfjorden Group presented here has provided a new stratigraphy and a more precise location and interpretation of the structures occurring below the Kapp Hansteen basal conglomerate.
Denna uppsats syftar till att tillhandahålla förståelse kring de bestämmande faktorer som påverkar användandet av factoring och de upplevda attityderna gentemot factoring. Uppsatsen kommer även tillhandahålla en samtida syn på factoring som finansieringsmetod och försöka förklara användandet med hjälp av finansiella teorier. Uppsatsen använder en kvantitativ forskningsstrategi med en kombination aThis thesis aims to provide an understanding regarding the determinants of the usage of factoring and the perceived attitudes towards factoring. It will also provide a contemporary view of factoring as a financing solution and try to explain the usage in the context of financial theories. The thesis uses a quantitative research strategy combined with a mixture of a deductive and inductive approach
INTRODUCTION: Ageing right care(fully) is a transnational research study which explores and maps an understanding of the care pathways between ageing in place and hospital at home policy and practices for older adults in Israel, the Netherlands and Sweden. The countries are suited to be compared where they have growing, ageing populations, a focus on healthcare reform and several policies to reduc
Jordan population have increased 3 million in the last five years. 1.5Million are refugees from Syria. 800 thousand are inside refugeecamps in the northern part of Jordan. 100 thousand are situated inZaatari camp which is located 10 kilometres east of Mafraq city. Thisenormous influx increased solid waste volume generated by 480 tonsdaily. The additional waste generation has exacerbated pre-existi
This chapter discusses the current problems and future prospects of the euro area. The author argues that the problem for the euro area is not the return of the nation-state, but that the nation-states never disappeared. A common currency requires common economic policies, which is largely lacking in the euro area. As a result, large economic and social imbalances have emerged. The chapter examine
The interaction of two confined coaxial jets has been studied using Computational Fluid Dynamics. Annular jet flows over 8 flat blade swirl generator. Numerical simulation uses RNG k- ϵ turbulence model. These models are suitable for turbulent swirl dominated flows. Intermediate swirl injector has been simulated and the flow patterns for non-reactive and reactive cases are contrasted. Low swirling
