  1. 1. Type Ia Supernovae : Homogeneity and Diversity

    Author : Gabriele Garavini; Ariel Goobar; David Branch; Stockholms universitet; []
    Keywords : Physics;

    Abstract : The use of type Ia supernovae as distance estimators has shown that about 75% of the energy content of the universe has a negative equation of state parameter and thus, drives the acceleration of the universe. Constraining the exact nature of this energy is one of the main goals in cosmology. READ MORE

  2. 2. Testing Homogeneity and Unit Root Restrictions in Panels

    Author : Johan Blomquist; Nationalekonomiska institutionen; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Non-stationary panels; Panel unit root tests; Cross-sectional dependence; Homogeneity testing;

    Abstract : This thesis is divided into two distinct parts. The first part contains three chapters, co-authored with Joakim Westerlund, that deal with the analysis of unit root testing, and the second part consists of two chapters on slope homogeneity testing. READ MORE

  3. 3. ”I don’t believe the meaning of life is all that profound” : A study of Icelandic teenagers’ life interpretation and values

    Author : Gunnar J. Gunnarsson; Sven Hartman; Geir Skeie; Stockholms universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; life interpretation; life philosophy; existential questions; values; teenagers; homogeneity; plurality; security; insecurity; religious education.; Education; Pedagogik; pedagogik; Education;

    Abstract : What do teenagers recount about themselves and their interpretation of life and values, and what characterises individual teenagers’ perceptions and statements? What is the relation between teenagers’ life interpretation and values and social circumstances? What challenges to school religious education do the teenagers’ perceptions and statements represent? These questions are central to the study Icelandic Teenagers’ Life Interpretation and Values.The purpose of the study was to investigate some central elements in teenagers’ life interpretation so as to discuss the results in terms of social circumstances in Iceland and of school religious education.

  4. 4. An Experimental Study of Liquid Steel Sampling

    Author : Ola Ericsson; Pär Jönsson; Andrey Karasev; Malin Hallberg; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid steel sampling; slag protection; filling velocity; solidification rate; sample homogeneity; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : Sampling of liquid steel to control the steel making process is very important in the steel industry. However, there are numerous types of disposable samplers and no united standard for sampling. The goal in this study is to investigate the effect of slag protection type and sample geometry on sampling parameters and sample homogeneity. READ MORE

  5. 5. New Concepts in Administration of Drugs in Tablet Form : Formulation and Evaluation of a Sublingual Tablet for Rapid Absorption, and Presentation of an Individualised Dose Administration System

    Author : Susanne Bredenberg; Christer Nyström; Carla Caramella; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Pharmaceutics; Interactive mixture; Dose homogeneity; Disintegration; Bioadhesion; Oromucosal delivery; Sublingual tablet; Rapid absorption; Individual dosage; Drug dispensing device; Galenisk farmaci; Pharmaceutics; Galenisk farmaci; galenisk farmaci; Pharmaceutics;

    Abstract : This thesis presents two new concepts in oral drug administration and the results of evaluation of some relevant formulation factors.Investigation into improving the homogeneity of mixtures for tableting indicated that it may be possible to obtain interactive dry mixtures of micronised drugs containing drug proportions as low as 0.015% w/w.
