The orbital approximation for stellar streams is the assumption that all stars in a stream can be described as following the same orbit. In this thesis, I evaluate this approximation as a method for constraining the potential of the Milky Way. I wrote a program in MATLAB which integrates the orbits of test particles in a potential model which resembles that of the Milky Way's halo and disc. Th
This study investigates online material published in reaction to a Science magazine report showing the absence of peer-review and editorial processes in a set of fee-charging open access journals in Biology. Quantitative and qualitative textual analyses are combined to map conceptual relations in these reactions; and to explore how understandings of scholarly communication and publishing relate to
Background: It is not known whether the recently described break in the trend in hip fracture incidence in many settings applies in both women and men, depends on changes in bone mineral density (BMD) or changes in other risk factors, or whether it is apparent in both urban and rural settings. Methods: We evaluated changes in annual hip fracture incidence from 1987 to 2002 in Swedish men aged >= 6
Timber structures and wooden element are in general affected by moisture and moisture variation in different ways. Their hygroscopic properties result in adsorption of water when wetted and in desorption when dried. Because the volume of wood is not constant but varies with the moisture content, uneven distribution of moisture will result in induced eigen-stresses because of internal restraint hyg
Reaction of the tricobalt carbyne cluster [Co-3(mu(3)-CH)(CO)(9)] with chiral diphosphines of the Josiphos and Walphos families affords the new clusters [Co-3(mu(3)-CH)(CO)(7)(P-P*)] in good yield (P-P* = J004 (1), J005 (2), J007 (3), W001 (4), W003 (5)). The new alkylidyne tricobalt clusters, and the previously known [Co-3(mu(3)-CH)(CO)(7)(mu-J003)], have been tested as catalysts/catalyst precurs
Background: Despite the fact that HIV-positive women carry an increased risk of developing cervical cancer (CC) in comparison with HIV-negative women, HIV and CC screening programs in many developing countries have remained unintegrated. The objective of this study is to explore perceptions and preferences of community members in Uganda, including women, men, and village health teams, regarding th
The aim of this study was to analyse the relationship between different biometric parameters and sapflow and growth, respectively, in order to assess their potential for use in scaling. The effect of thinning on these relationships was also investigated. The studied stand consisted of Scots pine (ca. 60%), Norway spruce (ca. 35%) and downy birch (ca. 5%). Sapflow was measured by the tissue heat-ba
Corporate cash holdings have an important role in the financial management of corporations. Firms hold cash for various reasons, Keynes (1936) states the reasons to be of transaction, precautionary and speculative nature, respectively, and firms’ cash policies differ both on an industry and firm level. Previous empirical studies mainly deal with the determinants and behavior of corporate cash hold
Samhället genomgick under 1900-talet stora förändringar. Välfärdsstatens socialpolitiska reformer gjorde att familjens roll förändrades – allt fler av de funktioner som tidigare var förbehållna familjen kom nu att övertas av samhället. Kvinnans ekonomiska självständighet och jämställdhet med mannen stärktes. Kvinnor blev också i allt större utsträckning verksamma på arbetsmarknaden. SkilsmässotaleThe society has experienced major changes in the 20th century. The social politics of the Swedish welfare state has impacted the family role. Important functions which were earlier carried out within the family, is now provided by the social welfare system. The economical independency of the spouses and gender equality strengthened during this period. An additional important factor for the reforma
Issue of study: There is no clear framework for IPR negotiation to support the establishment of I-U collaboration by balancing their competing interests. For I-U collaborations within the same country, several sets of guidelines have been produced to emphasize IPR-issues in R&D collaborations. These have helped to increase awareness, but corporations and universities still report problems when
The main purpose of the project has been to find the root cause to the failure of a machine component used to secure some vital parts (later on referred to as the pins) of a packing machine. It was already known that the failure had to do with fatigue, but the actual mechanisms were quite unknown. Measurements on the components did not indicate forces that should lead to failure. The components of
Delivery of goods at the port of discharge is an obligation incurred upon the carrier under a contract of carriage by sea. The extent of the carrier’s obligation is to give the consignee a reasonable time to take proper delivery of the goods against presentation of an original B/L. Delivery of goods is currently not regulated in any international laws on carriage of goods by sea, it is only regula
Syftet med uppsatsen är att utreda om det finns motsättningar mellan den aktiebolagsrättsliga vinstmaximeringsprincipen och de krav som ställs på vårdgivare utifrån lagstiftning som ska skydda patienters och vårdtagares intressen. Vidare är syftet att undersöka vilken utformning av lagstiftningen som är lämplig och diskutera detta ur ett rättsekonomiskt perspektiv. Vinster i välfärden är en kontrThe purpose of this paper is to investigate whether there are conflicts between the principle of profit maximization in company law and the demands placed on caregivers based on legislation that protects patients and care receivers' interests.

In recent years, mobile phones and GPS have become increasingly common tools for people working in elderly care. In the home care service, the mobile phone is now completely central to planning who will do what and when. The aim of the study was to investigate how home care staff shape their view of care work in the light of the mobile phones they use. The method chosen for this study was qualitiv
Abstract Hydrogen as an alternative energy carrier has been up for discussion over decades. Perhaps this time, however, the political momentum and global technical context could be advantageous enough for the hydrogen economy to finally materialize. Despite investments from the EU commission up to €470 billion in renewable hydrogen, there are economical challenges in the way of decarbonisation of
Var och en som har blivit anklagad för ett brott åtnjuter en rätt till tystnad och att betraktas som oskyldig genom det straffprocessuella förfarandet fram till en eventuellt fällande dom. Dessa grundläggande rättigheter tillförsäkras den tilltalade genom artikel 6.1 och 6.2 EKMR. Som en följd av dessa rättigheter ligger bevisbördan i brottmål uteslutande på åklagaren, vilket medför en rätt för deEveryone charged with criminal offense has the right to remain silent and to be presumed innocent until proven guilty in criminal proceedings. The accused is assured these fundamental rights according to article 6.1 and 6.2 ECHR. Due to these rights, the burden of proof must lie on the prosecutor, which means that the accused has the right to remain completely passive during criminal proceedings.
