The aim of this study was to investigate the correlations between epidemiological indices (objective) and self-perceived oral health (subjective) in adolescents at school level, and to study gender differences in epidemiological indices and in self-perceived oral health. The study comprised two sets of data from Skaraborg County, Sweden: 1. Self-reported questionnaires answered by adolescents at a
This thesis combines corpus-based, experimental and instrumental methods to investigate how professional speakers of English use prosody to signal important textual boundaries above the sentence level. In an initial study, prosodic features included in the transcriptions of the Spoken English Corpus, or readily derivable from these, are investigated. These include minor and major tone-unit length
Nucleic acids have many unique structural features that offer reliable means of recognizing and monitoring many compounds of medical or environmental importance. In recent years, there has been an enormous increase in the use of nucleic acids as a tool to determine the chemical compounds of environmental and clinical interest and the major research activities in these areas have been directed towa
Good decision-making relies on accurate, timely and reliable information. This can be supported by having intelligent packaging which allows data on the whereabouts and condition of goods to be automatically captured along a supply chain. This research reveals that, although interest in intelligent packaging in Swedish manufacturing industries is high, actual use is limited. Nevertheless, this res
Denna uppsats problematiserar och undersöker målbolagsstyrelsens ställning vid offentliga uppköpserbjudanden genom att belysa oklarheter som råder kring målbolagsstyrelsens agerande, framförallt till följd av att ABL inte har anpassats till takeover-reglerna och vice versa. Målbolagsstyrelsens komplexa ställning exemplifieras i denna uppsats av en utredning av vilka överväganden och vilket aktieboThis thesis problematizes and investigates the role of the board in a public company facing a friendly takeover bid. It does this by illuminating ambiguities which concern actions of the target company board, due to the fact that the Swedish Companies Act and the Swedish Takeover Rules have not been brought into conformity with one another. The complicated role of the board is exemplified by the i
Popular Abstract in Swedish Avhandlingens huvudfråga är hur språket används i skolämnet naturkunskap i två mångkulturella gymnasieklassrum. Språket ses som vår viktigaste resurs för utveckling och lärande i olika skolämnen. Att elever får rikliga tillfällen att lära sig hantera ämnesrelevant språk blir enligt ett sådant synsätt avgörande för vilket språk de utvecklar och vad de lär sig. SpråkutvecThe purpose of the thesis is to investigate how language is used in the school subject Natural Science in two multi-cultural upper seconday classrooms. Previous research points to the fact that second language students are not successful in their school work. The reason usually given is the students' inadequate knowledge of their second language. Today's curricular directives of the Swedish school
A humus soil with a pH(H2O) of 4.9 was limed to a pH of 7.5 and was incubated together with samples from unlimed and field limed (pH 6.1) soils at 5, 20 and 30degreesC for up to 80 days. The changes in the phospholipid fatty acid (PLFA) pattern were most rapid for the bacterial community of the soil incubated at 30degreesC, while no changes were found in the soil incubated at 5degreesC. The respon
Concerns over the threats of terrorism, piracy, and armed robbery against ships resulted in a number of International Maritime Organization (IMO) initiatives in the 1980s and 1990s including, inter alia, the establishment of an anti-piracy program, the development of guidelines for ship security, and the adoption of the Convention for the Suppression of Unlawful Acts Against the Safety of Maritime
A plant bioreactor has enormous capability as a system that supports many biological activities, that is, production of plant bodies, virus-like particles (VLPs), and vaccines. Foreign gene expression is an efficient mechanism for getting protein vaccines against different human viral and nonviral diseases. Plants make it easy to deal with safe, inexpensive, and provide trouble-free storage. The b
ECG markers derived from the P-wave are used frequently to assess atrial function and anatomy, e.g. left atrial enlargement. While having the advantage of being routinely acquired, the processes underlying the genesis of the P-wave are not understood in their entirety. Particularly the distinct contributions of the two atria have not been analyzed mechanistically. We used an in silico approach to
Bentonite is to be used as a sealing material for long-term storage of radioactive waste. During permafrost periods the buffer may freeze, causing the following: montmorillonite dehydration, ice formation, and pressure build-up that may fracture the surrounding rock. No previous study has been done on freezing of bentonite in saline water. Using small and wide angle X-ray scattering, the present s
Popular Abstract in Swedish Hur löser den intellektuelle politikern problem och hur skapas kontakten med den politiska omgivningen? Svaren på frågorna skall kortfattat presenteras och är intressanta för politiker, partier, väljare och forskare. Svaren visar nämligen hur intellektuella politiker under kristider producerar och presenterar innovativa lösningar som kan få stor betydelse för samhällsutA new theory on the intellectual politician, which has the ability to produce a designed type of problem-solving, has been developed from political science theory, cognitive theory as well as art theory. A cognitive concept, modified integrative complexity, consisting of four sub-concepts, frame reflection, differentiation, reframing and integration has been developed. The relation between politic
To keep balance when standing or walking on a surface inclined in the roll plane, the cat modifies its body configuration so that the functional length of its right and left limbs becomes different. The aim of the present study was to assess the motor cortex participation in the generation of this left/right asymmetry. We recorded the activity of fore- and hindlimb-related pyramidal tract neurons
The results of a treatment method on adenocarcinoma corpus uteri stage I-II based upon cytometrically measured DNA ploidy are presented. All patients had a simple hysterectomy. Adjuvant treatment (postoperative vaginal brachytherapy) were given only to those patients with non-diploid tumours regardless of stage and grade. A total of 1,634 women with endometroid adenocarcinoma corpus uteri stage I-
The increased demand for high purity nanoparticles (NPs) of defined geometry necessitates the continuous development of generation routes. One of the most promising physical techniques for producing metal, semiconductor or alloy NPs in the gas phase is spark discharge NP generation. The technique has a great potential for up-scaling without altering the particles. Despite the simplicity of the set
In the European Union (EU), mandatory durability ecodesign requirements have recently been set for vacuum cleaners and lighting products. Durability standards for additional product groups are expected in the future and it is also envisioned that durability issues will be integrated in the EU energy labelling scheme. Durability standards can bring environmental benefits, but there are several meth
